It relates to doorstops that are also used for

In a typical prior art, for example, as disclosed in Patent Document 1, each fitting leg connected to a door stop body is inserted into a pair of grooves formed in a vertical frame of a wooden door frame, and the fitting legs are formed. The pressing claws press against the inner wall of the groove to make it difficult to separate from the groove. This doorstop is made entirely of hard synthetic resin and is an elongated material that is extruded.

JP 2007-23584 A JP 2011-115616 A

In the prior art of Patent Document 1, when the door is closed and hits the door stopper, the pressure contact claw strongly pushes the inner wall of the groove, and the frictional force caught on the inner wall prevents the door stopper from coming off the door frame. . In the prior art, the frictional force between the pressing claw and the inner wall is insufficient, and the insertion leg of the door stopper cannot be easily separated from the groove.

SUMMARY OF THE INVENTION An object of the present invention is to provide a door stopper that does not come off from a groove formed in a door frame.

The retaining structure of the present invention is implemented in the technical field of Patent Document 2, for example. In a structure in which legs, which are supporting pieces provided in a product display device for displaying product prices, etc., are inserted and held by being inserted into grooves extending in the lateral direction of shelf boards of product display shelves in supermarkets, It is desirable to prevent the bent leg from slipping out of the groove. The retaining structure is required not only in Patent Document 2 but also in various other technical fields.

Another object of the present invention is to provide a retaining structure that prevents the legs fitted in the grooves from falling off.

A component or the like is sometimes referred to only in one drawing out of a plurality of drawings in which it is shown.

As to the reference numerals, the components of the second leg 130 that fit into the second groove 8 in the embodiment of FIGS. Indicated by added numbers. 1 to 6 and other embodiments of FIGS. 7 to 10 and 11, the reference numerals of FIGS. and may be omitted to avoid redundancy.

The present invention mainly refers to the embodiment shown in FIGS. 1 to 6 and other embodiments shown in FIGS. 7 to 10,
In the door stopper 10 (110) attached to the first and second grooves 7 and 8 respectively formed in pairs on the upstream side and the downstream side of the closing movement direction 6 in the door frame 1 in which the door 5 closes,
(a) A U-shaped door in which a first side portion 21 that moves in the closing movement direction 6 in which the door 5 closes and collides with a second side portion 22 downstream in the closing movement direction 6 is connected at a top portion 23. a hit body 20;
a first connecting portion 15 connected to the first side portion 21 of the doorstop main body 20;
a first leg portion 30 connected to the first connection portion 15 and fitted into the first groove 7;
a second connecting portion 16 (116) connected to the second side portion 22 of the doorstop main body 20;
A second leg portion 50 (130) connected to the second connection portion 16 (116) and fitted into the second groove 8,
(b) the first leg 30 is
(b1) A first base end portion 31 connected to the doorstop main body 20 via the first connection portion 15,
a first outer protrusion 32 extending upstream in the closing movement direction 6 and facing the first inner surface 11 on the upstream side of the first groove 7;
a first support protrusion 33 extending downstream in the closing movement direction 6 and facing the second inner surface 12 on the downstream side of the first groove 7,
Within the first groove 7, the distance W33 (FIG. 3) between the end facing the first inner surface 11 of the first outer projection 32 and the end facing the second inner surface 12 of the first supporting projection 33 is the first a first base end portion 31 that is less than the width W7 of the groove 7 (that is, W33<W7);
(b2) The first distal end portion 41 arranged deeper in the depth direction of the first groove 7 than the first proximal end portion 31,
a first elastic projection 42 extending upstream in the closing movement direction 6 and elastically contacting the first inner surface 11;
a first tip portion 41 extending downstream in the closing movement direction 6 and having a first inner convex portion 43 facing the second inner surface 12;
(b3) A door stopper characterized by having a first connection portion 45 that connects the first base end portion 31 and the first tip portion 41 .

According to the present invention, the first leg 30 and the second leg 50 (130) of the doorstop 10 (110) are fitted into the first and second grooves 7, 8 respectively. The configuration of the second leg portion 50 (130) of the doorstop 10 (110) may be different from that of the first leg portion 30 as in the embodiments of FIGS. It may be the same or similar as in the ten other embodiments.

When the door 5 moves to close the opening and collides with the first side portion 21 of the doorstop body 20, the impact force in the closing movement direction 6 (right in FIG. 1) of the first side portion 21 is applied to the first connection It acts downstream in the closing movement direction 6 (to the right in FIG. 1) at the connection location of the portion 15 with the first side 21 (for example, the end 27 of the first side end 24 in FIG. 3 described below). Therefore, the first support protrusion 33 that continues to the first connection portion 35 of the first proximal end portion 31 is pressed against the second inner surface 12 . Therefore, the frictional force between the first support projection 33 and the second inner surface 12 is generated and increased, and the first leg 30 is prevented from being separated from the first groove 7 upward in FIG.

Furthermore, due to the action of this impact force, the first base end portion 31, and therefore the first connecting portion 45, rotates around the position of contact with the second inner surface 12 of the first supporting protrusion 33 as a fulcrum. (reference numeral 37 in the enlarged view of FIG. 3) occurs. Therefore, the first elastic convex portion 42 of the first distal end portion 41 is pressed and crushed by the first inner surface 11 and deformed, and the contact area with the first inner surface 11 increases. As a result, the frictional force between the first elastic convex portion 42 and the first inner surface 11 increases, preventing the first leg portion 30 from separating upward in FIG. 1 from the first groove 7 . In this way, the moment increases in proportion to the impact force with which the door 5 collides with the first side portion 21. Therefore, when the impact force is large, (p1) corresponds to a large amount of deformation of the first elastic convex portion 42. The contact area with the first inner surface 11 increases further. By increasing the frictional force between the convex portion 42 and the first inner surface 11 , it is possible to reliably prevent the first leg portion 30 from being detached from the first groove 7 .

On the other hand, in the prior art disclosed in Patent Document 1, the hard synthetic resin press-contact claw strongly pushes the inner wall of the groove and prevents the door stopper from leaving the groove only by the frictional force of being caught on the inner wall. Therefore, in the prior art, there is a problem that it is insufficient to make it difficult to detach. The present invention solves this prior art problem.

In the first groove 7, the first base end portion 31 has a distance W33 between the end portion of the first outer convex portion 32 facing the first inner surface 11 and the end portion of the first supporting convex portion 33 facing the second inner surface 12. (FIG. 3) is less than the width W7 of the first groove 7 (that is, W33<W7), the operation of fitting the first base end portion 31 into the first groove 7 is facilitated. . W33=W7 may be satisfied.

The second leg 50 (130) is
It abuts on the third inner surface 13 on the upstream side of the second groove 8 and the fourth inner surface 14 on the downstream side of the second groove 8 .

For example, when the door 5 does not collide with the first side portion 21, the first outer protrusion 32 and the first elastic protrusion 42 are applied to the first inner surface 11, and the first inner protrusion 43 is applied to the second inner surface 12. are in contact with each other,
When the door 5 collides with the first side portion 21 , the first support protrusion 33 contacts the second inner surface 12 .

When the amount of deformation of the first elastic convex portion 42 at the time of collision is small, the first supporting convex portion 33 may not come into contact with the second inner surface 12 .

The first to fourth inner surfaces 11 to 14 are, for example, parallel planes.

In order to generate a moment in the clockwise direction 37 at the time of collision, the first support protrusion 33 should be positioned at the first proximal end 31 more than the first connecting portion 46 of the first connecting portion 45 in the depth direction of the first groove 7 . It has an inwardly disposed configuration.

The first connecting portion 15 and the second connecting portion 16 (116), which are components of the present invention, are connected by the first base end portions 31, 131 and the second base end portion 51 themselves or by a portion thereof. , or a portion of the doorstop main body 20, etc., and the invention disclosed in this specification includes these configurations.

The present invention mainly refers to FIG.
The first connecting portion 45 has a first connecting portion 46 connected to the first base end portion 31 and a second connecting portion 47 connected to the first distal end portion 41,
The first connecting portion 46 of the first connecting portion 45 is closer to the first outer protrusion 32 than the connecting portion 35 connected to the first connecting portion 15,
The first connecting portion 45 is characterized by extending from the first connecting portion 46 to the second connecting portion 47 inward in the depth direction of the first groove 7 so as to approach the second inner surface 12 .

According to the present invention, in the first connecting portion 45 , (p2) the first connecting portion 46 connected to the first proximal end portion 31 is more outwardly convex than the first connecting portion 35 connected to the first connecting portion 15 . 32 (to the left in FIG. 3, closer to the first inner surface 11), and (q2) the second connecting portion 47 is inward in the depth direction of the first groove 7 from the first connecting portion 46 (downward in FIG. 3). , the position is closer to the second inner surface 12 (thus obliquely to the lower right in FIG. 3). With these configurations (p2) and (q2), when the door 5 collides with the first side portion 21, the clockwise direction of FIGS. The moment can be reliably generated.

Therefore, the first elastic convex portion 42 is pressed against the first inner surface 11 to maximize the amount of deformation thereof, thereby increasing the contact area between the first elastic convex portion 42 and the first inner surface 11 . By increasing the frictional force with 11, it becomes more reliable to prevent the first leg 30 from coming off from the first groove 7.

According to the present invention, in the first connecting portion 45, the first connecting portion 46 is arranged as far as possible from the first supporting protrusion 33 by the configuration (p2), and the configuration By (q2), the first connecting portion 45 can be arranged obliquely in the first groove 7 to the lower right in FIG. 3 so as to extend over as long a distance as possible. With these configurations (p2), (q2), when the door 5 collides with the first side 21, the clockwise moment in FIG. , the amount of displacement in which the second connecting portion 47 approaches the first inner surface 11 can be increased as much as possible. Therefore, the first elastic convex portion 42 is pressed against the first inner surface 11 to maximize the amount of deformation thereof, thereby increasing the contact area between the first elastic convex portion 42 and the first inner surface 11 . By increasing the frictional force with 11, it becomes more reliable to prevent the first leg 30 from coming off from the first groove 7.

The present invention mainly refers to FIG.
The first outer protrusion 32 extends outward in the depth direction of the first groove 7 as it approaches the first inner surface 11,
The first support protrusion 33 extends inward in the depth direction of the first groove 7 as it approaches the second inner surface 12,
The first elastic convex portion 42 is located closer to the inside in the depth direction of the first groove 7 than the first inner convex portion 43,
The first inner protrusion 43 is characterized by extending outward in the depth direction of the first groove 7 as it approaches the second inner surface 12 .

According to the invention, the first outer protrusion 32 approaches the first inner surface 11 (to the left in FIG. 3) and the first inner protrusion 43 approaches the second inner surface 12 (to the right in FIG. 3). ), it extends outward in the depth direction of the first groove 7 (upward in FIG. 3). That is, the first outer protrusion 32 extends diagonally to the upper left in FIG. 3, and the first inner protrusion 43 extends diagonally to the upper right in FIG. Therefore, the first outer convex portion 32 and the first inner convex portion 43 prevent the first leg portion 30 from being detached from the first groove 7 by engaging with the first and second inner surfaces 11 and 12 . They act as claws that are as large as possible.

The present invention mainly refers to FIG.
The door stop body 20 has a first side end 24,
The first side end portion 24 continues to the end portion 26 on the side of the first groove 7 in the first side portion 21 of the door stop body 20 , and the depth increases from the first groove 7 as it becomes downstream in the closing movement direction 6 of the door 5 . extending away in the direction of
The first connection portion 15 extends from the downstream end portion 27 of the door 5 in the closing movement direction 6 at the first side end portion 24 toward the first inner surface 11 toward the depth direction inner side of the first groove 7 . It is characterized by

According to the present invention, (p3) the first side end portion 24 of the door stop main body 20 is connected to the end portion 26 of the first side portion 21 on the side of the first groove 7 (lower side in FIG. It extends away from the first groove 7 in the depth direction (upward in FIG. 3 and thus obliquely to the upper right in FIG. 3) as it goes downstream in the direction of movement 6 (to the right in FIG. 1). (q3) The first connecting portion 15 is positioned inwardly in the depth direction of the first groove 7 (downward in FIG. 3) from the downstream end 27 of the first side end 24 in the closing movement direction 6 of the door 5 . , it extends closer to the first inner surface 11 (thus, obliquely to the lower left in FIG. 3).

With these configurations (p3) and (q3), when the door 5 collides with the first side portion 21 and a rightward or upper rightward force in FIG. can reliably generate the clockwise moment in FIG. This moment ensures an increase in the frictional force with the first inner surface 11 due to the pressing deformation of the first elastic convex portion 42 .

When the door 5 does not collide with the first side portion 21 , the elastic force between the first elastic protrusion 42 and the first inner surface 11 causes the first outer protrusion 32 to move toward the first inner surface 11 and the first inner protrusion 32 . The portions 43 are each elastically abutted against the second inner surface 12 . Therefore, the separation of the first leg portion 30 from the first groove 7 is reliably prevented. At this time, there is a slight gap Δ33 (=W33−W7) between the first support protrusion 33 and the second inner surface 12 . The door 5 moves to close and collides with the first side portion 21 of the doorstop main body 20, and as described above, the first support projection 33 of the first base end portion 31 is pushed by the elastic force of the first elastic projection 42. When it abuts against the second inner surface 12, for example, the gap Δ33 exists between the first outer convex portion 32 and the first inner surface 11, and at this time, the first inner convex portion of the first tip portion 41 exists. A gap may be formed between 43 and the second inner surface 12 due to pressure deformation of the first elastic convex portion 42 .

The second leg portion 50 (130) abuts against the third inner surface 13 and the fourth inner surface 14 of the second groove 8 and is prevented from being separated from the second groove 8. As shown in FIG.

The present invention mainly refers to FIG.
In the door stopper 18 attached to the groove 7 formed in the door frame 1,
(i) a doorstop body 20 having a side portion 21 that moves in the closing movement direction 6 in which the door 5 closes and collides;
a connecting portion 15 connected to the side portion 21 of the doorstop main body 20;
A leg portion 30 connected to the connection portion 15 and fitted into the groove 7,
(j) the legs 30 are
(j1) A base end portion 31 connected to the doorstop main body 20 via the connection portion 15,
an outer convex portion 32 extending upstream in the closing movement direction 6 and facing the first inner surface 11 on the upstream side of the groove 7;
a support protrusion 33 extending downstream in the closing movement direction 6 and facing the second inner surface 12 on the downstream side of the groove 7,
Within the groove 7, the distance W33 (FIG. 11) between the end of the outer protrusion 32 facing the first inner surface 11 and the end of the supporting protrusion 33 facing the second inner surface 12 is less than the width W7 of the groove 7 (that is, , W33<W7), and
(j2) the distal end portion 41 arranged deeper in the depth direction of the groove 7 than the proximal end portion 31,
an elastic convex portion 42 extending upstream in the closing movement direction 6 and elastically contacting the first inner surface 11;
a tip portion 41 extending downstream in the closing movement direction 6 and having an inner convex portion 43 facing the second inner surface 12;
(j3) A door stopper characterized by having a connection portion 45 that connects the base end portion 31 and the tip end portion 41 .

The door stop 18 of the present invention includes, for example, a configuration in which a leg 30 is provided in association with a single side 21 as shown in FIG. 11, and components corresponding to FIGS. Put a reference mark. In an embodiment, components such as side 22, leg 50 of FIG. 1, and leg 130 of FIG. 7 are omitted. The effects, actions, etc. of the doorstop 18 of the embodiment are the same as or similar to those described above, and will be briefly described.

According to the invention, the single leg 30 of the door stop 18 is fitted in the groove 7. As shown in FIG.

When the door 5 collides with the side portion 21 of the doorstop main body 20, the support protrusion 33 is pressed against the second inner surface 12 by the impact force in the closing movement direction 6 (right in FIG. 11). and the second inner surface 12 generates and increases frictional force, thereby preventing the leg portion 30 from being detached from the groove 7 upward in FIG. Further, due to the action of this impact force, the proximal end portion 31, and therefore the connecting portion 45, is subjected to a clockwise moment 37 in FIG. occurs, the elastic convex portion 42 of the distal end portion 41 is pressed and crushed by the first inner surface 11 and deformed, the contact area with the first inner surface 11 increases, and the elastic convex portion 42 and the first inner surface 11 11, and the leg portion 30 is prevented from separating from the first groove 7 upward in FIG. In this way, the moment increases in proportion to the impact force with which the door 5 collides with the side portion 21. Therefore, when the impact force is large, (p8) the first elastic convex portion 42 corresponding to the large deformation amount The contact area with the first inner surface 11 further increases, and at this time, (q8) a large pressing force acts on the first inner surface 11 of the elastic convex portion 42. By increasing the frictional force with the inner surface 11 , it is possible to reliably prevent the legs 30 from coming off the grooves 7 .

When the door 5 does not collide with the side portion 21 , the outer protrusion 32 contacts the first inner surface 11 and the inner protrusion 43 contacts the second inner surface 12 due to the resilience of the elastic protrusion 42 with the first inner surface 11 . , elastically abut against each other, and the separation of the leg portion 30 from the groove 7 is reliably prevented. At this time, there is a slight gap Δ33 (=W33−W7) between the supporting protrusion 33 and the second inner surface 12 . Further, when the door 5 moves to close and collides with the side portion 21 of the doorstop main body 20 and the support protrusion 33 contacts the second inner surface 12, for example, a , the gap Δ33 exists, and at this time, a gap may be generated between the inner convex portion 43 of the tip portion 41 and the second inner surface 12 due to the pressing deformation of the elastic convex portion 42 .

When the amount of deformation of the first elastic convex portion 42 at the time of collision is small, the first supporting convex portion 33 may not come into contact with the second inner surface 12 .

The present invention mainly refers to FIGS. 12 to 14,
In the retaining structure 210 attached to the groove 7 formed in the holding body 201 and holding the held body 207,
(L) a held body body 220 having a force acting portion 221 on which a force acts in a predetermined force acting direction 206 of the held body 207;
a connecting portion 15 connected to the main body 220 of the held body;
A leg portion 30 connected to the connection portion 15 and fitted into the groove 7,
(m) the legs 30 are
(m1) The base end portion 31 connected to the main body 220 of the held body through the connecting portion 15,
an outer convex portion 32 extending upstream in the force acting direction 206 and facing the first inner surface 11 on the upstream side of the groove 7;
a support protrusion 33 extending downstream in the force acting direction 206 and facing the second inner surface 12 on the downstream side of the groove 7,
Within the groove 7, the distance W33 between the end of the outer protrusion 32 facing the first inner surface 11 and the end of the supporting protrusion 33 facing the second inner surface 12 is less than the width W7 of the groove 7 (that is, W33<W7 ) and the base end 31,
(m2) The distal end portion 41 disposed deeper in the groove 7 than the proximal end portion 31,
an elastic convex portion 42 extending upstream in the direction of force action 206 and elastically contacting the first inner surface 11;
a tip portion 41 extending downstream in the direction of force application 206 and having an inner convex portion 43 facing the second inner surface 12;
(m3) A connecting portion 45 that connects a first connecting portion 46 closer to the outer convex portion 32 than the connecting portion 35 connecting to the connecting portion 15 in the base end portion 31 and a second connecting portion 47 connecting to the distal end portion 41; The retaining structure 210 is characterized by having

For example, as in the embodiments shown in FIGS. 12 to 14, the present invention is applied to the groove 7 extending in the horizontal direction of the shelf board 213 of the holder 201, which is the product display shelf in a supermarket. It is a retainer structure 210 in which the leg portion 30 provided in the holding body 207 is fitted and inserted to hold. The retainer structure 210 according to the present invention prevents a product or the like displayed on the shelf board 213 from moving undesirably and hitting the force acting portion 221 provided in the held body 220 of the held body 207. This prevents the leg portion 30 from falling out of the groove 7 when an external force such as an impact force acts in a predetermined force acting direction 206.例文帳に追加

For example, when the product moves and collides with the force acting portion 221 provided on the body 220 to be held, the impact force in the force acting direction 206 (left side in FIGS. 205 (for example, the end 27 of the side end 24 in FIG. 13 described later) downstream in the direction of force action 206 (leftward in FIGS. 12 to 14). Therefore, the support protrusion 33 that continues to the connection portion 35 of the base end portion 31 is pressed against the second inner surface 12 . Therefore, the frictional force between the support protrusion 33 and the second inner surface 12 is generated and increased, and the leg 30 is prevented from being separated from the groove 7 upward in FIGS.

Furthermore, due to the action of this impact force, the base end portion 31, and thus the connecting portion 45, rotates counterclockwise in FIG. 13, a moment 237) is generated in the enlarged view of FIG. Therefore, the elastic convex portion 42 of the distal end portion 41 is pressed and crushed by the first inner surface 11 and deformed, thereby increasing the contact area with the first inner surface 11 . As a result, the frictional force between the elastic convex portion 42 and the first inner surface 11 is increased, and the leg portion 30 is prevented from detaching upward from the groove 7 in FIGS. In this way, since the moment increases in proportion to the impact force that collides with the force acting portion 221, when the impact force is large, (p12) the first inner surface 11 corresponding to the large amount of deformation of the elastic convex portion 42 is further increased, and (q12) a large pressing force acts on the first inner surface 11 of the elastic convex portion 42. By increasing the frictional force, it is possible to reliably prevent the legs 30 from coming off the grooves 7 .

On the other hand, in the prior art of Patent Document 2 mentioned above, protrusions made of a soft material are formed on the support pieces to prevent them from slipping out of the grooves by contact with the inner surfaces of the grooves. In addition, in the prior art of Patent Document 1 mentioned above, there is no concept of using a soft material. Therefore, the prior arts of Patent Documents 1 and 2 described above have a problem that it is insufficient to prevent them from coming off easily. The present invention solves this prior art problem.

In the groove 7, the base end portion 31 has a distance W33 (FIGS. 13 and 14) between the end of the outer protrusion 32 facing the first inner surface 11 and the end of the support protrusion 33 facing the second inner surface 12. , less than the width W7 of the groove 7 (that is, W33<W7), the operation of fitting the base end portion 31 into the groove 7 is facilitated. W33=W7 may be satisfied.

For example, when an external force such as a collision does not act on the force acting portion 221, the outer convex portion 32 and the elastic convex portion 42 elastically contact the first inner surface 11, and the inner convex portion 43 elastically contacts the second inner surface 12. contact,
When an external force acts on the force acting portion 221 , the first supporting protrusion 33 contacts the second inner surface 12 .

When the amount of deformation of the elastic convex portion 42 due to the external force is small, the first supporting convex portion 33 may not come into contact with the second inner surface 12 .

The first to fourth inner surfaces 11 to 14 are, for example, parallel planes.

To generate a moment in the counterclockwise direction 237, such as during a collision in the embodiment of FIGS. 7 in the depth direction.

The present invention mainly refers to FIGS. 13 and 14,
The connecting portion 45 has a first connecting portion 46 connected to the base end portion 31 and a second connecting portion 47 connected to the distal end portion 41,
The first connecting portion 46 of the connecting portion 45 is closer to the outer convex portion 32 than the connecting portion 35 connected to the connecting portion 15,
The connecting portion 45 is characterized in that it extends from the first connecting portion 46 to the second connecting portion 47 inward in the depth direction of the groove 7 so as to approach the second inner surface 12 .

According to the present invention, in the connecting portion 45, (p13) the first connecting portion 46 connected to the base end portion 31 is closer to the outer convex portion 32 than the connecting portion 35 connected to the connecting portion 15 (right side in FIGS. 13 and 14). and (q13) the second connecting portion 47 moves inward from the first connecting portion 46 in the depth direction of the groove 7 (downward in FIGS. 13 and 14) to the second inner surface. 12 (and thus diagonally to the lower left in FIGS. 13 and 14). With these configurations (p13) and (q13), when a force acts on the force acting portion 221 due to a collision with a product or the like, the counterclockwise rotation of FIGS. The moment in direction 237 can be reliably generated.

Therefore, the elastic convex portion 42 is pressed against the first inner surface 11 to maximize the amount of deformation thereof, thereby increasing the contact area with the first inner surface 11 and increasing the friction between the elastic convex portion 42 and the first inner surface 11 . With increased force, it becomes even more reliable to prevent the legs 30 from leaving the grooves 7 .

According to the present invention, in the connection portion 45, the configuration (p13) allows the first connection portion 46 to be separated from the supporting protrusion 33 by as long a distance as possible, and the configuration (q13) provides , the connecting portion 45 can be arranged obliquely in the groove 7 to the lower left in FIGS. 13 and 14 so as to extend as long as possible. With these configurations (p13) and (q13), when a force acts on the force acting portion 221 due to a collision with a product or the like, the counterclockwise rotation of FIGS. The moment in direction 237 allows the second connecting portion 47 to move as close to the first inner surface 11 as possible. Therefore, the elastic convex portion 42 is pressed against the first inner surface 11 to maximize the amount of deformation thereof, thereby increasing the contact area with the first inner surface 11 and increasing the friction between the elastic convex portion 42 and the first inner surface 11 . With increased force, it becomes even more reliable to prevent the legs 30 from leaving the grooves 7 .

The present invention mainly refers to FIGS. 13 and 14,
The outer convex portion 32 extends outward in the depth direction of the groove 7 as it approaches the first inner surface 11,
The support protrusion 33 extends inward in the depth direction of the groove 7 as it approaches the second inner surface 12,
The elastic convex portion 42 is located closer to the inside in the depth direction of the groove 7 than the inner convex portion 43,
The inner protrusion 43 is characterized by extending outward in the depth direction of the first groove 7 as it approaches the second inner surface 12 .

According to the invention, the outer protrusion 32 approaches the first inner surface 11 (to the right in FIGS. 13 and 14) and the inner protrusion 43 approaches the second inner surface 12 (to the left in FIGS. 13 and 14). ), it extends outward in the depth direction of the groove 7 (upward in FIGS. 13 and 14). 13 and 14, and the inner convex portion 43 extends diagonally to the upper left in FIGS. 13 and 14, respectively. Therefore, the outer convex portion 32 and the inner convex portion 43 function as claws that exhibit as large a force as possible to engage with the first and second inner surfaces 11 and 12 to prevent the leg portion 30 from coming off the groove 7. fulfill

The present invention mainly refers to FIGS. 13 and 14,
The held body main body 220 has a side end portion 24,
The side end portion 24 continues to the groove 7 side end portion 26 of the force acting portion 221 of the held body 220, and extends away from the groove 7 in the depth direction as it becomes downstream in the force acting direction 206,
The connection portion 15 is characterized by extending from the downstream end portion 27 of the side end portion 24 in the direction of force application 206 toward the first inner surface 11 as it goes inward in the depth direction of the groove 7 .

According to the present invention, (p14) the side end portion 24 of the main body 220 to be held continues to the end portion 26 of the force acting portion 221 on the side of the groove 7 (lower side in FIGS. 13 and 14), 13 and 14, it extends away from the groove 7 in the depth direction (upward in FIGS. 13 and 14, and thus diagonally to the upper left in FIGS. 13 and 14). In addition, (q14) the connection portion 15 extends from the downstream end portion 27 of the side end portion 24 in the force acting direction 206 toward the depth direction inner side of the groove 7 (below the force acting direction 206). (thus obliquely to the lower right in FIGS. 13 and 14).

With these configurations (p14) and (q14), when a product or the like collides with the force applying portion 221 and a left or upper left force in FIGS. can reliably generate the left counterclockwise moment 237 described above. This moment ensures an increase in the frictional force with the first inner surface 11 due to the pressing deformation of the elastic convex portion 42 .

When no external force acts on the force applying portion 221 , the elastic force between the elastic convex portion 42 and the first inner surface 11 pushes the outer convex portion 32 to the first inner surface 11 and the inner convex portion 43 to the second inner surface 12 . , resiliently in contact with each other. Therefore, it is possible to reliably prevent the legs 30 from being separated from the grooves 7 . At this time, there is a slight gap Δ33 (=W33−W7) between the supporting protrusion 33 and the second inner surface 12 . When an external force acts on the force applying portion 221 and, as described above, the supporting convex portion 33 of the proximal end portion 31 comes into contact with the second inner surface 12 against the elastic force of the elastic convex portion 42, the outer convex portion 32 and For example, the gap Δ33 exists between the first inner surface 11 and the inner convex portion 43 of the distal end portion 41 and the second inner surface 12. At this time, a gap is generated due to the pressing deformation of the elastic convex portion 42. good too.

An embodiment will be described with reference to FIGS. 1 to 6. FIG. FIG. 1 is a horizontal sectional view showing a state in which a door stopper 10 is attached to a vertical frame 2 of a door frame 1 according to an embodiment of the present invention, and FIG. 2 is a door stopper in a natural state where no external force acts. It is sectional drawing which shows the tool 10 and shows the mounting|wearing method to the vertical frame 2 collectively. A door frame 1 is provided at an opening of a room in a building. A door frame 1 includes a vertical frame 2, a lower frame 3, an upper frame and another vertical frame, and is made of wood or synthetic resin, for example. A door 5, which is a hinged door, is attached to the door frame 1 so as to be angularly displaceable about a vertical axis perpendicular to the paper surface of FIG. The movement range of 5 is limited, and the gap is closed. The door 5 may be a sliding door or the like that moves horizontally in the closing movement direction 6 for closing the opening.

The vertical frame 2 has a pair of first and second grooves 7 and 8 on the upstream side (left side in FIG. 1) and downstream side (right side in FIG. 1) in the closing movement direction 6 of the door 5. formed respectively. The first and second inner surfaces 11, 12 forming the first groove 7 and the third and fourth inner surfaces 13, 14 forming the second groove 8 are planes perpendicular to and parallel to the paper surface of FIG.

The doorstop device 10 basically includes a doorstop main body 20 , a first leg portion 30 fitted into the first groove 7 , and a second leg portion 50 fitted into the second groove 8 . The doorstop main body 20 has a U-shape in which a first side portion 21 with which the door 5 collides when it moves in the closing movement direction 6 and a second side portion 22 on the downstream side of the closing movement direction 6 are connected at a top portion 23 . formed in The first side 21 is provided with a cushioning piece 76, which may be hollow, for example as shown in FIG. The first leg portion 30 is connected to the first connection portion 15 from the first side end portion 24 that continues to the first side portion 21 of the door stop body 20 . The second leg portion 50 is connected to the second connection portion 16 from the second side end portion 25 that continues to the second side portion 22 of the doorstop main body 20 .

FIG. 3 is an enlarged sectional view showing the first leg portion 30 fitted in the first groove 7 and its vicinity. The first leg portion 30 has a first base end portion 31 connected to the doorstop main body 20 via the first connection portion 15 , a first tip portion 41 , and a first connecting portion 45 . The first base end portion 31 has a first outer convex portion 32 and a first support convex portion 33 . The first outer protrusion 32 extends upstream in the closing movement direction 6 and faces the first inner surface 11 on the upstream side of the first groove 7 . The first support protrusion 33 extends downstream in the closing movement direction 6 and faces the second inner surface 12 on the downstream side of the first groove 7 . At the first base end portion 31 in the first groove 7, the distance W33 ( 3) is less than the width W7 of the first groove 7 (ie W33<W7). This facilitates the operation of fitting the first base end portion 31 into the first groove 7 . As clearly shown in FIG. 3, the end portion of the first support projection 33 facing the second inner surface 12 is rounded in an arc shape, so that it hits the second inner surface 12 with the impact force of the door 5. When they come into contact with each other, it is possible to reliably generate a clockwise moment 37 in FIG. 3 with the contact position as a fulcrum.

The first distal end portion 41 is arranged inside the first groove 7 in the depth direction (lower in FIG. 3) than the first proximal end portion 31 . The first tip portion 41 has a first elastic convex portion 42 and a first inner convex portion 43 . The first elastic projection 42 extends upstream in the closing movement direction 6 and elastically contacts the first inner surface 11 . The first inner convex portion 43 extends downstream in the closing movement direction 6 and faces the second inner surface 12 . The end of the first inner protrusion 43 facing the second inner surface 12 is rounded in an arc shape, as clearly shown in FIG.

The first connecting portion 45 connects a first connecting portion 46 connected to the first base end portion 31 and a second connecting portion 47 connected to the first distal end portion 41 .

When the door 5 does not collide with the first side portion 21, the first outer protrusion 32 and the first elastic protrusion 42 contact the first inner surface 11, and the first inner protrusion 43 elastically contacts the second inner surface 12. abut each other. When the door 5 collides with the first side portion 21 via the cushioning piece 76 , the first support protrusion 33 contacts the second inner surface 12 .

The second leg 50 contacts the third inner surface 13 on the upstream side of the second groove 8 and the fourth inner surface 14 on the downstream side of the second groove 8 .

When the door 5 collides with the first side portion 21 of the door stop body 20 , the impact force in the closing movement direction 6 (right in FIGS. 1 and 3 ) of the first side portion 21 is applied to the first connecting portion 15 . It acts downstream in the closing movement direction 6 (to the right in FIG. 3) on the end 27 of the first side end 24 where it connects with the side 21 . Therefore, the first support protrusion 33 that continues to the first connection portion 35 of the first proximal end portion 31 is pressed against the second inner surface 12 . Therefore, the frictional force between the first support protrusion 33 and the second inner surface 12 is generated and increased, and the first leg 30 is prevented from separating upward in FIG. 3 from the first groove 7 .

Furthermore, due to the action of this impact force, the first base end portion 31, and therefore the first connecting portion 45, rotates around the position of contact with the second inner surface 12 of the first supporting protrusion 33 as a fulcrum. , a clockwise moment in FIG. Therefore, the first elastic convex portion 42 of the first distal end portion 41 is pressed and crushed by the first inner surface 11 and deformed, and the contact area with the first inner surface 11 increases. As a result, the frictional force between the first elastic convex portion 42 and the first inner surface 11 increases, preventing the first leg portion 30 from separating upward in FIG. 3 from the first groove 7 . In this way, the moment increases in proportion to the impact force with which the door 5 collides with the first side portion 21. Therefore, when the impact force is large, (p1) corresponds to a large amount of deformation of the first elastic convex portion 42. The contact area with the first inner surface 11 increases further. By increasing the frictional force between the convex portion 42 and the first inner surface 11 , it is possible to reliably prevent the first leg portion 30 from being detached from the first groove 7 .

The first elastic projection 42 has a shape that is easy to insert into the first groove 7 and requires impact resilience.

When the door 5 does not collide with the first side portion 21 , the elastic force between the first elastic protrusion 42 and the first inner surface 11 causes the first outer protrusion 32 to move toward the first inner surface 11 and the first inner protrusion 32 . The portions 43 are each elastically abutted against the second inner surface 12 . Therefore, the separation of the first leg portion 30 from the first groove 7 is reliably prevented. At this time, there is a slight gap Δ33 (=W33−W7) between the first support protrusion 33 and the second inner surface 12 . The door 5 moves to close and collides with the first side portion 21 of the doorstop main body 20, and as described above, the first support projection 33 of the first base end portion 31 is pushed by the elastic force of the first elastic projection 42. When it abuts against the second inner surface 12, the gap Δ33 exists between the first outer convex portion 32 and the first inner surface 11, and at this time, the first inner convex portion 43 of the first tip portion 41 is formed. and the second inner surface 12 due to pressure deformation of the first elastic convex portion 42 . In another embodiment, the distance W33 between the end facing the first inner surface 11 of the first outer projection 32 and the end facing the second inner surface 12 of the first supporting projection 33 in the groove 7 is It may be equal to the width W7 of the groove 7 (ie W33≦W7).

Residual portions other than the first elastic convex portion 42 and the shock absorbing piece 76 of the doorstop device 10, such as the doorstop main body 20, the first and second connecting portions 15, 16, the first and second base end portions 31, 51 , the first inner convex portion 43, the second leg portion 50, the first and second side end portions 24, 25, etc. can be made of hard synthetic resin, for example. Since this material is an elastic material, the concept of a snap fit is adopted to make the first connecting portion 45 thicker and shorter to make the first connecting portion 45 less likely to bend. can strongly adhere to the first inner surface 11 and withstand a large repulsive force. The hard synthetic resin may be, for example, polyvinyl chloride resin, ABS resin, polyethylene, polypropylene, etc., and has a relatively larger elastic modulus than the material of the first elastic projections 42 .

The first elastic convex portion 42 of the doorstop 10 may be made of elastic, viscoelastic, sticky, soft, or tacky synthetic resin material, such as urethane-based material, rubber, or soft polyvinyl chloride resin. , an elastomer, and the like. The door stopper 10 may be manufactured by extrusion molding together with the first elastic convex portion 42, the shock absorbing piece 76 and the remainder. The cushioning piece 76 may be made of a soft elastic synthetic resin or the like. The buffer piece 76 may be omitted.

In the first connecting portion 45, (p2) the first connecting portion 46 connected to the first base end portion 31 is closer to the first outer convex portion 32 than the first connecting portion 35 connected to the first connecting portion 15 (p2). (left side, first inner surface 11 side), the first connecting portion 46 is arranged as far as possible from the first supporting convex portion 33, and (q2) the second connecting portion 47 It is located closer to the second inner surface 12 as it goes inward (lower in FIG. 3) in the depth direction of the first groove 7 from the connecting portion 46 (thus obliquely to the lower right in FIG. 3), and the first connecting portion 45 can be arranged obliquely in the first groove 7, to the lower right in FIG. 3, extending over as long a distance as possible. As a result, when the door 5 collides with the first side portion 21, it is possible to reliably generate a clockwise moment in FIG. Therefore, the first elastic convex portion 42 is pressed against the first inner surface 11 to maximize the amount of deformation thereof, thereby increasing the contact area between the first elastic convex portion 42 and the first inner surface 11 . By increasing the frictional force with 11, it becomes more reliable to prevent the first leg 30 from coming off from the first groove 7.

The first outer protrusion 32 extends outward in the depth direction of the first groove 7 (upward in FIG. 3) as it approaches the first inner surface 11 (leftward in FIG. 3), that is, upward to the left in FIG. It extends obliquely and its tip is formed at an acute angle. The first inner protrusion 43 extends outward in the depth direction of the first groove 7 (upward in FIG. 3) as it approaches the second inner surface 12, that is, obliquely extends upward and to the right in FIG. Therefore, the first outer convex portion 32 and the first inner convex portion 43 prevent the first leg portion 30 from being detached from the first groove 7 by engaging with the first and second inner surfaces 11 and 12 . They act as claws that are as large as possible. The first elastic convex portion 42 is located closer to the inside (lower side in FIG. 3 ) in the depth direction of the first groove 7 than the first inner convex portion 43 . The first support protrusion 33 extends inward in the depth direction of the first groove 7 (downward in FIG. 3) as it approaches the second inner surface 12 (rightward in FIG. 3).

The configuration of the first side end portion 24 of the doorstop main body 20 will be described. (p3) The first side end portion 24 continues to the end portion 26 of the first side portion 21 of the door stop body 20 on the side of the first groove 7 (lower side in FIG. 3), it extends away from the first groove 7 in the depth direction (upward in FIG. 3, and thus obliquely upward to the upper right in FIG. 3). (q3) The first connecting portion 15 is positioned inward in the depth direction of the first groove 7 (downward in FIG. 3) from the downstream end portion 27 in the closing movement direction 6 of the door 5 at the first side end portion 24. As it goes, it approaches the first inner surface 11 (thus, it extends obliquely to the lower left in FIG. 3). With these configurations (p3) and (q3), when the door 5 collides with the first side portion 21 and a rightward or upper rightward force in FIG. can reliably generate the clockwise moment in FIG. This moment ensures an increase in the frictional force with the first inner surface 11 due to the pressing deformation of the first elastic convex portion 42 .

FIG. 4 is an enlarged cross-sectional view showing the second leg 50 fitted in the second groove 8 and its vicinity. The second leg portion 50 has a second base end portion 51 connected to the doorstop main body 20 via the second connection portion 16 , a second tip portion 61 , and a second connecting portion 65 . The second base end portion 51 has a second outer convex portion 52 . The second outer protrusion 52 extends downstream in the closing movement direction 6 (to the right in FIG. 4) and faces the fourth inner surface 14 on the downstream side of the second groove 8 . The second distal end portion 61 is arranged inside the second groove 8 in the depth direction (lower in FIG. 4 ) than the second proximal end portion 51 . The second tip portion 61 has a second inner convex portion 62 . The second inner protrusion 62 extends upstream in the closing movement direction 6 and faces the third inner surface 13 . The second connecting portion 65 is connected to a third connecting portion 66 closer to the second outer protrusion 52 than the second connecting portion 55 connected to the second connecting portion 16 in the second proximal end portion 51 and the second distal end portion 61. The continuous fourth connecting portion 67 is connected. The second outer protrusion 52 and the second inner protrusion 62 are in contact with the fourth inner surface 14 and the third inner surface 13, respectively.

In the operation of the second leg 50 , the impact force on the first side 21 of the door stop body 20 by the door 5 is transferred from the top 23 through the second side 22 to the second side 22 of the second connecting part 16 . downstream of the closing movement direction 6 (to the right in FIG. 4) on the end 29 of the second side end 25 which is the connection position with the . Therefore, the second outer convex portion 52 connected to the second connection portion 55 of the second proximal end portion 51 of the second leg portion 50 is pressed against the fourth inner surface 14 . Therefore, the frictional force between the second outer convex portion 52 and the fourth inner surface 14 is generated and increased, preventing the second leg portion 50 from separating upward in FIG. 4 from the second groove 8 .

Furthermore, due to the action of this impact force, the second base end portion 51, and thus the second connecting portion 65, is rotated clockwise in FIG. moment occurs. Therefore, the second inner convex portion 62 of the second distal end portion 61 is pressed against the third inner surface 13 to increase the frictional force with the third inner surface 13, and the second leg portion 50 moves from the second groove 8 to the position shown in FIG. It is prevented from detaching upward. In this way, the frictional force between the second outer convex portion 52 and the fourth inner surface 14 and the frictional force between the second inner convex portion 62 and the third inner surface 13 increase in response to the impact force by the door 5, The second leg 50 is prevented from leaving the second groove 8 .

When the door 5 does not hit the first side 21, the second outer projection 52 is on the fourth inner surface 14, the second inner projection 62 is on the third inner surface 13, the door stop body 20 and the second leg 50 Due to the resilience of synthetic resin materials such as these, frictional force is exerted by contact with each other. Therefore, the second leg portion 50 is prevented from being separated from the second groove 8 .

The second connecting portion 65 is formed so as to extend from the third connecting portion 66 to the fourth connecting portion 67 inward in the depth direction of the second groove 8 so as to approach the third inner surface 13 . The second connecting portion 65 extends from the third connecting portion 66 to the fourth connecting portion 67 inward in the depth direction of the second groove 8 (lower side in FIG. 4) and closer to the third inner surface 13 (thus, the second groove 8 obliquely (lower left in FIG. 4). Therefore, when the door 5 collides with the first side 21, the clockwise moment in FIG. 3 By increasing the frictional force between the second inner projection 62 and the third inner surface 13 due to the force pressing against the inner surface 13 , it is possible to reliably prevent the second leg 50 from coming off the second groove 8 .

The second side end portion 25 of the doorstop main body 20 will be described. (p4) The second side end portion 25 of the doorstop main body 20 continues to the end portion 28 of the second side portion 22 on the side of the second groove 8 (lower side in FIG. leftward in FIG. 4), it extends away from the second groove 8 in the depth direction (upward in FIG. 4, and therefore obliquely upward in FIG. 4 as a whole). In addition, (q4) the second connecting portion 16 extends from the upstream end portion 29 of the second side end portion 25 in the closing movement direction 6 of the door 5 toward the depth direction inner side of the second groove 8 (lower side in FIG. 4). , it extends closer to the fourth inner surface 14 (thus, obliquely to the lower right in FIG. 4).

Due to these configurations (p4) and (q4) of the second side end 25, the door 5 collides with the first side 21 and a force acts on the end 28 of the second side 22 in the lower right direction in FIG. At this time, the second outer convex portion 52 of the second base end portion 51 is strongly pressed against the fourth inner surface 14, and the clockwise moment in FIG. can. This moment increases the pressing force of the second inner convex portion 62 against the third inner surface 13, ensuring an increase in frictional force.

A first inclined guide surface 71 and a second inclined guide surface 72 are formed on the first leg portion 30, and a third inclined guide surface 73 and a fourth inclined guide surface 74 are formed on the second leg portion 50. be done. The first inclined guide surface 71 of the first inner convex portion 43 extends outward in the depth direction of the first groove 7 as it approaches the second inner surface 12 (rightward in FIGS. 1 and 3) from the second connecting portion 47. It extends smoothly (upward in FIGS. 1 and 3, and thus obliquely upward and to the right in FIGS. 1 and 3 as a whole). The second inclined guide surface 72 of the first connecting portion 45 is smooth so as to move away from the first inner surface 11 from the first connecting portion 46 to the second connecting portion 47 (diagonally to the lower right in FIGS. 1 and 3). extends to The third inclined guide surface 73 of the second inner convex portion 62 extends outward in the depth direction of the second groove 8 as it approaches the third inner surface 13 (to the left in FIGS. 1 and 4) from the fourth connecting portion 67. It extends smoothly (upward in FIGS. 1 and 4, and thus diagonally to the upper left in FIGS. 1 and 4 as a whole). The fourth inclined guide surface 74 of the second connecting portion 65 is smoothly moved away from the fourth inner surface 14 from the third connecting portion 66 to the fourth connecting portion 67 (diagonally to the lower left in FIGS. 1 and 4). extends to

Therefore, the first leg portion 30 is such that the left-right spacing in FIGS. ), and the second leg portion 50 is such that the left and right spacing between the third inclined guide surface 73 and the fourth inclined guide surface 74 in FIGS. 1, downward in FIG. 4) is V-shaped. Therefore, as shown in FIG. 5, it is easy to fit the first and second legs 30, 50 into the first and second grooves 7, 8, respectively, and the doorstop 10 with good construction workability is realized. be done. When the fitting operation is performed, the first elastic projection 42 can be elastically compressed and deformed by coming into contact with the first inner surface 11 or the like, so there is no hindrance to the construction work.

Referring again to FIG. 2, the first and second grooves 7, 8 are shown in a simplified manner, and the door stopper 10 is shown in its natural state with no external force acting thereon. The distance between the second inner surface 12 and the third inner surface 13 is W1, and the distance between the first inner surface 11 and the fourth inner surface 14 is W3. The distance between the first inner protrusion 43 and the second inner protrusion 62 of the door stopper 10 in the natural state is W2, and the distance between the first outer protrusion 32 and the second outer protrusion 52 is W4. At this time, it is formed so that the following equations (1) and (2) are established.
W2 < W1 (1)
W3 < W4 (2)

FIG. 5 is a cross-sectional view for explaining a method of installing the synthetic resin doorstop 10 in the first and second grooves 7 and 8 and constructing it. By configuring the door stopper 10 so as to satisfy the formulas (1) and (2), the first inclined guide surface 71 and the second inclined guide surface 72 of the first leg portion 30 described above can be 1. As shown in FIG. 3, it is V-shaped, and the third inclined guide surface 73 and the fourth inclined guide surface 74 of the second leg 50 are V-shaped as shown in FIGS. Together, at least one of the first to fourth inclined guide surfaces 71 to 74 is adapted to fit the first and second legs 30, 50 into the first and second grooves 7, 8 respectively. Door stop while contacting open ends 82, 81, 83, 84 of second, first, third, fourth inner surfaces 12, 11, 13, 14 facing first to fourth inclined guide surfaces 71 to 74 of By pushing the main body 20 inward in the depth direction of the first and second grooves 7 and 8 (downward in FIG. 5) as shown in the pushing directions 86 and 87 in FIG. It is easy to put on using its elasticity. Thus, the first and second legs 30, 50 can be fitted into the first and second grooves 7, 8 at the same time and mounted on the vertical frame 2 of the door frame 1. As shown in FIG.

FIG. 6 is a cross-sectional view for explaining another embodiment of the present invention, in which the synthetic resin doorstop 10 is installed in the first and second grooves 7 and 8 for construction. After first fitting the first leg 30 into the first groove 7, the second leg 50 can then be fitted into the second groove 8 in the pressing direction 88 shown in FIG. Construction can also be performed in the reverse order. In this way, construction workability is good. When performing the fitting operation in FIGS. 5 and 6, the first elastic convex portion 42 can contact the first inner surface 11 or the like and be elastically compressed and deformed, so there is no hindrance to the construction work.

The second leg portion 50 shown in FIGS. 1 to 6 does not have the first elastic convex portion 42 of the first leg portion 30, so it is easy to manufacture.

Another embodiment will be described with reference to FIGS. 7 to 10. FIG. FIG. 7 is a horizontal cross-sectional view showing a state in which a door stopper 110 is attached to the vertical frame 2 of the door frame 1 according to another embodiment of the present invention, and FIG. It is sectional drawing which shows the hit tool 110 and shows the mounting|wearing method to the vertical frame 2 collectively. The embodiment of FIGS. 7-10 is similar to the embodiment of FIGS. 1-6 described above, with like components having the same reference numerals, for example the description of first leg 30, etc. omitted. The components of the second leg 130 are indicated by the reference numerals corresponding to the first leg 30 plus 100, as described above, to simplify the description.

The doorstop device 110 basically includes a doorstop main body 20 , a first leg portion 30 fitted into the first groove 7 , and a second leg portion 130 fitted into the second groove 8 . The first leg portion 30 is connected to the first connection portion 15 from the first side end portion 24 that continues to the first side portion 21 of the door stop body 20 . The second leg portion 130 is connected to the second connection portion 116 from the second side end portion 125 that continues to the second side portion 22 of the doorstop main body 20 .

FIG. 9 is an enlarged cross-sectional view showing the second leg 130 fitted in the second groove 8 and its vicinity. The second leg portion 130 has a second base end portion 131 connected to the doorstop main body 20 via the second connection portion 116 , a second tip portion 141 , and a second connection portion 145 . The second base end portion 131 has a second outer convex portion 132 and a second support convex portion 133 . The second outer protrusion 132 extends upstream in the closing movement direction 6 and faces the third inner surface 13 on the upstream side of the second groove 8 . The second support protrusion 133 extends downstream in the closing movement direction 6 and faces the fourth inner surface 14 on the downstream side of the second groove 8 . At the second base end portion 131 in the second groove 8, the distance W133 between the end of the second outer protrusion 132 facing the third inner surface 13 and the end of the second support protrusion 133 facing the fourth inner surface 14 is , less than the width W8 of the second groove 8 (that is, W133<W8). This facilitates the operation of fitting the second base end portion 131 into the second groove 8 . As clearly shown in FIG. 9, the end portion of the second support protrusion 133 facing the fourth inner surface 14 is rounded in an arc shape, so that it hits the fourth inner surface 14 with the impact force of the door 5. When they come into contact with each other, it is possible to reliably generate a clockwise moment 137 in FIG. 9 with the contact position as a fulcrum.

The second distal end portion 141 is arranged inside the second groove 8 in the depth direction (lower in FIG. 9) than the second proximal end portion 131 . The second tip portion 141 has a second elastic convex portion 142 and a second inner convex portion 143 . The second elastic projection 142 extends upstream in the closing movement direction 6 and elastically contacts the third inner surface 13 . The second inner protrusion 143 extends downstream in the closing movement direction 6 and faces the fourth inner surface 14 . The end of the second inner protrusion 143 facing the fourth inner surface 14 is rounded in an arc shape, as clearly shown in FIG.

The second connecting portion 145 connects a third connecting portion 146 connected to the second proximal end portion 131 and a fourth connecting portion 147 connected to the second distal end portion 141 .

When the door 5 does not collide with the first side portion 21, the second outer convex portion 132 and the second elastic convex portion 142 contact the third inner surface 13, and the second inner convex portion 143 elastically contacts the fourth inner surface 14. abut each other. When the door 5 collides with the first side portion 21 via the cushioning piece 76 , the second support protrusion 133 contacts the fourth inner surface 14 .

When the door 5 collides with the first side portion 21 of the doorstop main body 20 , the impact force in the closing movement direction 6 (right in FIGS. 7 and 9 ) of the second side portion 22 is applied to the second connecting portion 116 . It acts downstream in the closing movement direction 6 (to the right in FIG. 9) on the end 129 of the second side end 125 where it connects with the side 22 . Therefore, the second support protrusion 133 connected to the second connection portion 135 of the second proximal end portion 131 is pressed against the fourth inner surface 14 . Therefore, the frictional force between the second support protrusion 133 and the fourth inner surface 14 is generated and increased, and the second leg 130 is prevented from separating upward in FIG. 9 from the second groove 8 .

Furthermore, due to the action of this impact force, the second base end portion 131, and therefore the second connecting portion 145, rotates around the position of contact with the fourth inner surface 14 of the second supporting protrusion 133 as a fulcrum. , a clockwise moment in FIG. Therefore, the second elastic convex portion 142 of the second distal end portion 141 is pressed and crushed by the third inner surface 13 and deformed, and the contact area with the third inner surface 13 increases. As a result, the frictional force between the second elastic convex portion 142 and the third inner surface 13 increases, preventing the second leg portion 130 from separating upward in FIG. 9 from the second groove 8 . In this way, the moment increases in proportion to the impact force with which the door 5 collides with the first side portion 21. Therefore, when the impact force is large, (p9) corresponds to a large amount of deformation of the second elastic convex portion 142. The contact area with the third inner surface 13 increases further, and at this time, (q9) a large pressing force acts on the third inner surface 13 of the second elastic convex portion 142. By increasing the frictional force between the protrusion 142 and the third inner surface 13 , it is possible to reliably prevent the second leg 130 from coming off the second groove 8 .

The second elastic protrusion 142 has a shape that is easy to insert into the second groove 8 and requires impact resilience.

When the door 5 does not collide with the first side portion 21, the elastic force of the second elastic protrusion 142 with the third inner surface 13 causes the second outer protrusion 132 to move toward the third inner surface 13 and the second inner protrusion. The portions 143 are resiliently in contact with the fourth inner surface 14 respectively. Therefore, the separation of the second leg portion 130 from the second groove 8 is reliably prevented. At this time, a slight gap Δ133 (=W133−W8) exists between the second support protrusion 133 and the fourth inner surface 14 . The door 5 moves to close and collides with the first side portion 21 of the doorstop main body 20, and as described above, the second support projection 133 of the second base end portion 131 is pushed by the elastic force of the second elastic projection 142. When it comes into contact with the fourth inner surface 14 against resistance, the gap Δ133 exists between the second outer convex portion 132 and the third inner surface 13, and at this time, the second inner convex portion 143 of the second tip portion 141 also exists. and the fourth inner surface 14 due to the pressing deformation of the second elastic convex portion 142 . In another embodiment, the distance W133 between the end of the second outer projection 132 facing the third inner surface 13 and the end of the second support projection 133 facing the fourth inner surface 14 in the groove 8 is It may be equal to the width W8 of the groove 8 (ie W133≦W8).

The rest of the doorstop 110 other than the first and second elastic projections 42, 142 and the cushioning piece 76 is made of the same or similar material as the doorstop 10, such as hard synthetic resin. be able to. The first and second elastic projections 42, 142 of the doorstop 110 may be made of the same or similar material as the doorstop 10 described above. The doorstop 110 may be manufactured by extrusion.

In the second connecting portion 145, (p10) the third connecting portion 146 connected to the second base end portion 131 is closer to the second outer convex portion 132 than the second connecting portion 135 connected to the second connecting portion 116 (see FIG. 9). The third connecting portion 146 is positioned as far as possible from the second supporting projection 133, and (q10) the fourth connecting portion 147 is located near the third inner surface 13). It is located closer to the fourth inner surface 14 as it goes inward (lower in FIG. 9) in the depth direction of the second groove 8 from the connecting portion 146 (thus, as a whole oblique to the lower right in FIG. 9). The connecting part 145 can be arranged obliquely in the second groove 8 to the lower right in FIG. 9 so as to extend over as long a distance as possible. As a result, when the door 5 collides with the first side portion 21, a clockwise moment in FIG. . Therefore, the second elastic convex portion 142 can be pressed against the third inner surface 13 to maximize the amount of deformation thereof, thereby increasing the contact area with the third inner surface 13 . By increasing the frictional force with the second leg 130, it becomes more reliable to prevent the second leg 130 from coming off the second groove 8.

The second outer protrusion 132 extends outward in the depth direction of the second groove 8 (upward in FIG. 9) as it approaches the third inner surface 13 (leftward in FIG. 9), that is, upward to the left in FIG. It extends obliquely and its tip is formed at an acute angle. The second inner protrusion 143 extends outward in the depth direction of the second groove 8 (upward in FIG. 9) as it approaches the fourth inner surface 14, that is, extends diagonally to the upper right in FIG. Therefore, the second outer convex portion 132 and the second inner convex portion 143 exert a force of engagement with the third and fourth inner surfaces 13 and 14 to prevent the second leg portion 130 from being detached from the second groove 8. They act as claws that are as large as possible. The second elastic convex portion 142 is positioned closer to the inside (lower side in FIG. 9) in the depth direction of the second groove 8 than the second inner convex portion 143 is. The second support protrusion 133 extends inward in the depth direction of the second groove 8 (downward in FIG. 9) as it approaches the fourth inner surface 14 (rightward in FIG. 9).

The configuration of the second side end portion 125 of the doorstop main body 20 of the doorstop device 110 will be described. (p11) The second side end portion 125 continues to the end portion 128 of the second side portion 22 of the door stop body 20 on the side of the second groove 8 (lower side in FIG. leftward in FIG. 9), it extends away from the second groove 8 in the depth direction (upward in FIG. 9, therefore obliquely to the upper left in FIG. 9). (q11) The second connection portion 116 is located inward in the depth direction of the second groove 8 (downward in FIG. 9) from the upstream end portion 129 of the second side end portion 125 in the closing movement direction 6 of the door 5. As it goes, it approaches the fourth inner surface 14 (and thus extends obliquely to the lower right in FIG. 9). With these configurations (p11) and (q11), when the door 5 collides with the first side portion 21 and a rightward or upper rightward force in FIG. A moment in the clockwise direction in FIG. This moment ensures an increase in the frictional force with the third inner surface 13 due to the pressing deformation of the second elastic convex portion 142 .

As described above, the first leg portion 30 is formed with the first inclined guide surface 71 of the first inner convex portion 43 and the second inclined guide surface 72 of the first connecting portion 45 . A third inclined guide surface 171 of the second inner convex portion 143 and a fourth inclined guide surface 172 of the second connecting portion 145 are formed on the second leg portion 130 . The third inclined guide surface 171 extends outward in the depth direction of the second groove 8 (in FIGS. 7 and 9) as it approaches the fourth inner surface 14 (to the right in FIGS. 7 and 9) from the fourth connecting portion 147. 7 and 9) smoothly. The fourth inclined guide surface 172 smoothly extends from the third connecting portion 146 to the fourth connecting portion 147 away from the third inner surface 13 (diagonally to the lower right in FIGS. 7 and 9).

Therefore, as described above, the first leg portion 30 is such that the left-right spacing between the first inclined guide surface 71 and the second inclined guide surface 72 in FIGS. 1, FIG. 3, FIG. 7) is V-shaped. 7 and 9 between the third inclined guide surface 171 and the fourth inclined guide surface 172 becomes smaller toward the second groove 8 (downward in FIGS. 7 and 9). It is V-shaped. Therefore, as shown in the following FIG. 10, the operation of fitting the first and second legs 30, 130 into the first and second grooves 7, 8 is easy, and the doorstop has good construction workability. 10 is realized.

Referring again to FIG. 8, the first and second grooves 7 and 8 are shown in a simplified manner, and the door stopper 110 is shown in its natural state with no external force acting thereon. W24 is the distance between the second inner surface 12 and the fourth inner surface 14, W13 is the distance between the first inner surface 11 and the third inner surface 13, and W13 is the distance between the first inner convex portion 43 and the second inner surface 110 of the doorstop 110 in the natural state. The distance from the projection 143 is W43, and the distance between the first outer projection 32 and the second outer projection 132 is W32. At this time, it is formed so that the following equations (3) and (4) are established.
W13 < W32 (3)
W24 < W43 (4)

FIG. 10 is a cross-sectional view for explaining a method of installing the synthetic resin doorstop 110 in the first and second grooves 7 and 8 and constructing it. By configuring the door stopper 110 so as to satisfy the formulas (3) and (4), the first inclined guide surface 71 and the second inclined guide surface 72 of the first leg portion 30 described above can be 1, 3 and 7, it is V-shaped, and the third inclined guide surface 171 and the fourth inclined guide surface 172 of the second leg 130 are V-shaped as shown in FIGS. Together with a configuration, the first to fourth inclined guide surfaces 71, 72, 171, 172 are provided for fitting the first and second legs 30, 130 into the first and second grooves 7, 8 respectively. open ends 82 of the second, first, fourth and third inner surfaces 12, 11, 14 and 13 facing the first to fourth inclined guide surfaces 71, 72, 171 and 172; By pushing the door stop main body 20 in the depth direction inner pushing directions 88, 89 (downward in FIG. 10) of the first and second grooves 7, 8 while contacting the synthetic resin door 81, 84, 83. It is easy to mount the hit tool 110 by utilizing its elasticity. Thus, the first and second legs 30, 130 can be fitted into the first and second grooves 7, 8 at the same time and mounted on the vertical frame 2 of the door frame 1. Moreover, it can be constructed in other orders. For example, after first fitting the first leg 30 into the first groove 7 , the second leg 130 can then be pressed to fit into the second groove 8 . In this way, construction workability is good. When performing the fitting operation, the first and second elastic protrusions 42, 142 can contact the first and third inner surfaces 11, 13, respectively, and can be elastically compressed and deformed, which interferes with the installation work. no.

In other embodiments of the present invention, the second legs 50, 130 may be replaced with other configurations.

FIG. 11 is a horizontal cross-sectional view showing a state in which a door stopper 18 is attached to the vertical frame 2 of the door frame 1 according to still another embodiment of the present invention. The door stopper 18 is mounted in the groove 7 formed in the door frame 1 and has a configuration in which a single side portion 21 is provided with a leg portion 30 associated therewith, and the side portion 22 and the leg portion of FIG. Components such as portion 50 and legs 130 of FIG. 7 are omitted. Components corresponding to those in FIGS. 1 to 10 are given the same reference numerals. Since the effects and actions of the doorstop 18 are the same as or similar to those described above, they will be briefly described.

The doorstop device 18 includes a doorstop main body 20 having a side portion 21 that moves in the closing movement direction 6 in which the door 5 closes and collides with the doorstop main body 20, a connecting portion 15 that continues to the side portion 21 of the doorstop main body 20, and the connecting portion 15. and legs 30 connected and fitted into the grooves 7 . The leg portion 30 includes a base end portion 31 connected to the doorstop main body 20 via the connection portion 15, a tip end portion 41 arranged inside the groove 7 from the base end portion 31 in the depth direction, and a base end portion 41 disposed inside the groove 7 from the base end portion 31. It has a connecting portion 45 that connects the portion 31 and the tip portion 41 . The base end portion 31 extends upstream in the closing movement direction 6 and has an outer convex portion 32 facing the first inner surface 11 on the upstream side of the groove 7 , and an outer convex portion 32 extending downstream in the closing movement direction 6 and facing the downstream side of the groove 7 . and a support protrusion 33 facing the second inner surface 12 . In the base end portion 31 , the distance W 33 ( FIG. 11 ) between the end facing the first inner surface 11 of the outer convex portion 32 and the end facing the second inner surface 12 of the supporting convex portion 33 within the groove 7 is less than the width W7 (that is, W33<W7). The distal end portion 41 has an elastic convex portion 42 that extends upstream in the closing movement direction 6 and elastically contacts the first inner surface 11 , and an inner convex portion that extends downstream in the closing movement direction 6 and faces the second inner surface 12 . a portion 43; The connecting portion 45 connects a first connecting portion 46 connected to the proximal end portion 31 and a second connecting portion 47 connected to the distal end portion 41 .

When the door 5 collides with the side portion 21 of the doorstop main body 20, the support protrusion 33 is pressed against the second inner surface 12 by the impact force in the closing movement direction 6 (right in FIG. 11). and the second inner surface 12 is generated and increased. Furthermore, due to the action of this impact force, a clockwise moment in FIG. The elastic convex portion 42 of 41 is pressed and crushed by the first inner surface 11 and deformed, the contact area with the first inner surface 11 increases, and the frictional force between the elastic convex portion 42 and the first inner surface 11 increases. As a result, the leg 30 is prevented from detaching upward in FIG. 11 from the first groove 7 . In this way, when the door 5 collides with the side portion 21 , the support protrusion 33 contacts the second inner surface 12 .

When the door 5 does not collide with the side portion 21 , the outer protrusion 32 contacts the first inner surface 11 and the inner protrusion 43 contacts the second inner surface 12 due to the resilience of the elastic protrusion 42 with the first inner surface 11 . , elastically abut against each other, and the separation of the leg portion 30 from the groove 7 is reliably prevented. At this time, there is a slight gap Δ33 (=W33−W7) between the supporting protrusion 33 and the second inner surface 12 . Further, when the door 5 is moved to close and collides with the side portion 21 of the doorstop body 20 and the support protrusion 33 contacts the second inner surface 12 , the gap between the outer protrusion 32 and the first inner surface 11 is reached. Δ33 exists, and at this time, a gap may be generated between the inner convex portion 43 of the distal end portion 41 and the second inner surface 12 due to the pressing deformation of the elastic convex portion 42 .

The first connecting portion 46 of the connecting portion 45 is located closer to the outer protrusion 32 than the connecting portion 35 connected to the connecting portion 15 , and the connecting portion 45 is positioned inwardly of the groove 7 in the depth direction from the first connecting portion 46 . The second connecting portion 47 is formed to extend closer to the second inner surface 12 .

Therefore, when the door 5 collides with the side portion 21, a clockwise moment in FIG.

The connecting part 45 of the door stopper 18 is formed thick and short to make the connecting part 45 difficult to bend, thereby making the elastic convex part 42 strongly adhere to the first inner surface 11 and capable of withstanding a large repulsive force. In this way, the elastic convex portion 42 may be pressed against the first inner surface 11 to maximize the amount of deformation. When the door 5 collides with the first side 21 , the amount of displacement of the second connecting portion 47 approaching the first inner surface 11 due to the clockwise moment in FIG. is increased as much as possible to increase the frictional force between the elastic convex portion 42 and the first inner surface 11 to further ensure that the leg portion 30 is prevented from coming off the groove 7 .

The outer convex portion 32 extends outward in the depth direction of the groove 7 as it approaches the first inner surface 11 , and the inner convex portion 43 extends inward in the depth direction of the groove 7 as it approaches the second inner surface 12 . The portion 42 is positioned closer to the inside in the depth direction of the groove 7 than the inner convex portion 43 , and the inner convex portion 43 extends outward in the depth direction of the groove as it approaches the second inner surface 12 . With this configuration, the outer convex portion 32 and the inner convex portion 43 function as claws that exhibit as large a force as possible to engage with the first and second inner surfaces 11 and 12 to prevent the leg portion 30 from being detached from the first groove 7. perform the function of

The doorstop main body 20 of the doorstop device 18 has a side end portion 24, and the side end portion 24 continues to the groove 7 side end portion 26 of the side portion 21 of the doorstop main body 20 and extends in the closing movement direction 6 of the door 5. and the connecting portion 15 extends inward in the depth direction of the groove 7 from the downstream end 27 in the closing direction 6 of the door 5 at the side edge 24. It extends closer to the first inner surface 11 as it grows. According to this configuration, when the door 5 collides with the first side portion 21 and a rightward or rightward force in FIG. can be reliably generated. This moment ensures an increase in the frictional force with the first inner surface 11 due to the pressing deformation of the elastic convex portion 42 .

The inner convex portion 43 has a smooth first inclined guide surface 71 extending outward in the depth direction of the groove 7 as it approaches the second inner surface 12 from the second connecting portion 47, and the connecting portion 45 It has a smooth second inclined guide surface 72 extending away from the first inner surface 11 from 46 to the connecting portion 47 .

According to this configuration, the first inclined guide surface 71 of the inner convex portion 43 moves outward in the depth direction of the groove 7 as it approaches the second inner surface 12 (rightward in FIG. 11) from the second connecting portion 47 ( 11 (and thus diagonally to the upper right of FIG. 11 as a whole). The second inclined guide surface 72 of the first connecting portion 45 smoothly extends from the first connecting portion 46 to the second connecting portion 47 away from the first inner surface 11 (diagonally to the lower right in FIG. 11). Therefore, the leg portion 30 has a V shape in which the left-right spacing in FIG. 11 between the first inclined guide surface 71 and the second inclined guide surface 72 decreases toward the groove 7 (downward in FIG. 11). Therefore, the operation of fitting the leg portion 30 into the groove 7 is easy, and the door stopper 10 with good construction workability is realized. When the fitting operation is performed, the elastic projection 42 can be elastically compressed and deformed by coming into contact with the first inner surface 11 or the like, so there is no hindrance to the installation work.

In order to fit the leg portion 30 into the groove 7 when mounting the door stopper 18, the first inclined guide surface 71 is brought into contact with the open end 82 of the second inner surface 12 facing the first inclined guide surface 71. , and the second inclined guide surface 72, while contacting the open end 81 of the first inner surface 11 facing the second inclined guide surface 72, pushing the door stop body 20 inward in the depth direction of the groove 7. , the leg portion 30 can be fitted into the groove 7 and mounted on the vertical frame 2 of the door frame 1. - 特許庁Moreover, it can be constructed in other orders. In this way, construction workability is good. When the fitting operation is performed, the elastic projection 42 can be elastically compressed and deformed by coming into contact with the first inner surface 11 or the like, so there is no hindrance to the installation work.

It has a projecting portion 217 and an opposing wall portion 218 rising from the projecting portion 217 .

For example, when the product on the shelf board 213 is handled by a worker, a purchaser, or the like, it moves on the shelf board 213 in the force acting direction 206 (leftward in FIG. 12) and collides with the force acting portion 221. , an external force such as an impact force acts on the force acting portion 221, and a moment in the counterclockwise direction 237 in FIG. 12 is sometimes generated. When these external forces act on the force acting portion 221 , the retaining structure 210 prevents the leg portion 30 from slipping out of the groove 7 .

FIG. 13 is an enlarged cross-sectional view showing the leg 30 fitted in the groove 7 in the circular portion XIII of FIG. 12 and its vicinity.

The retainer structure 210 basically includes a connecting portion 15 connected to the force acting portion 221 of the display body 220 and a leg portion 30 connected to the connecting portion 15 and fitted into the groove 7 . The leg portion 30 is connected to the connection portion 15 from the side end portion 24 connected to the force acting portion 221 of the display main body 220 .

The leg portion 30 shown in FIG. 13 has a base end portion 31 connected to the display device main body 220 via the connection portion 15, a tip end portion 41, and a connecting portion 45. As shown in FIG. The base end portion 31 has an outer convex portion 32 and a support convex portion 33 . The outer convex portion 32 extends upstream in the force acting direction 206 and faces the first inner surface 11 on the upstream side of the groove 7 . The support protrusion 33 extends downstream in the force acting direction 206 and faces the second inner surface 12 on the downstream side of the groove 7 . At the base end portion 31 in the groove 7, the distance W33 (FIG. 13) between the end of the outer projection 32 facing the first inner surface 11 and the end of the support projection 33 facing the second inner surface 12 is The width is less than W7 (that is, W33<W7). This facilitates the operation of fitting the base end portion 31 into the groove 7 . As clearly shown in FIG. 13, the end portion of the support protrusion 33 facing the second inner surface 12 is rounded in an arc shape, so that the impact force of the force acting portion 221 hits the second inner surface 12. When they come into contact with each other, a moment in the counterclockwise direction 237 in FIG. 13 can be reliably generated with the contact position as a fulcrum.

The distal end portion 41 is arranged deeper in the groove 7 than the proximal end portion 31 (lower in FIG. 13). The distal end portion 41 has an elastic convex portion 42 and an inner convex portion 43 . The elastic convex portion 42 extends upstream in the force acting direction 206 and elastically contacts the first inner surface 11 . The inner convex portion 43 extends downstream in the force acting direction 206 and faces the second inner surface 12 . The end of the inner protrusion 43 facing the second inner surface 12 is rounded in an arc shape, as clearly shown in FIG.

The connecting portion 45 connects a first connecting portion 46 connected to the proximal end portion 31 and a second connecting portion 47 connected to the distal end portion 41 .

When the product or the like does not collide with the force acting portion 221, the outer convex portion 32 and the elastic convex portion 42 elastically contact the first inner surface 11, and the inner convex portion 43 elastically contacts the second inner surface 12, respectively. When a product or the like collides with the force acting portion 221 , the supporting convex portion 33 contacts the second inner surface 12 .

When a product or the like collides with the force acting portion 221 , the impact force in the force acting direction 206 (left side in FIGS. 12 and 13 ) is applied to the end of the side end portion 24 that is the connection position with the force acting portion 221 of the connecting portion 15 . It acts on the portion 27 downstream in the force acting direction 206 (leftward in FIG. 13). Therefore, the support protrusion 33 that continues to the connection portion 35 of the base end portion 31 is pressed against the second inner surface 12 . Therefore, the frictional force between the support protrusion 33 and the second inner surface 12 is generated and increased, and the leg 30 is prevented from detaching upward in FIG. 13 from the groove 7 .

Furthermore, due to the action of this impact force, the proximal end portion 31, and therefore the connecting portion 45, rotates counterclockwise in FIGS. A directional moment is generated. Therefore, the elastic convex portion 42 of the distal end portion 41 is pressed and crushed by the first inner surface 11 and deformed, thereby increasing the contact area with the first inner surface 11 . As a result, the frictional force between the elastic convex portion 42 and the first inner surface 11 is increased, and the leg portion 30 is prevented from leaving the groove 7 upward in FIG. In this way, since the moment increases in proportion to the impact force with which the product or the like collides with the force acting portion 221, when the impact force is large, (p15) the first moment corresponding to the large amount of deformation of the elastic convex portion 42 The contact area with the inner surface 11 further increases, and at this time (q15) a large pressing force acts on the first inner surface 11 of the elastic convex portion 42. By increasing the frictional force with the leg portion 30, it is possible to reliably prevent the leg portion 30 from being detached from the groove 7.例文帳に追加

The elastic convex portion 42 has a shape that is easy to insert into the groove 7 and requires impact resilience.

When the product or the like does not collide with the force acting portion 221 , the elastic force between the elastic convex portion 42 and the first inner surface 11 causes the outer convex portion 32 to contact the first inner surface 11 and the inner convex portion 43 to contact the second inner surface 12 . , resiliently contact each other. Therefore, it is possible to reliably prevent the legs 30 from being separated from the grooves 7 . At this time, there is a slight gap Δ33 (=W33−W7) between the supporting protrusion 33 and the second inner surface 12 . When a product or the like collides with the force acting portion 221 and, as described above, the supporting convex portion 33 of the base end portion 31 contacts the second inner surface 12 against the elastic force of the elastic convex portion 42, the outer convex portion 32 and the first inner surface 11, and at this time, a gap is generated between the inner convex portion 43 of the distal end portion 41 and the second inner surface 12 due to the pressing deformation of the elastic convex portion 42. good too. In another embodiment, the distance W33 between the end of the outer projection 32 facing the first inner surface 11 and the end of the supporting projection 33 facing the second inner surface 12 in the groove 7 is equal to the width of the groove 7. It may be equal to W7 (ie W33 ≤ W7).

The rest of the retaining structure 210 in the indicator main body 220 other than the elastic convex portion 42, for example, the force acting portion 221, the connection portion 15, the proximal end portions 31 and 51, the inner convex portion 43, the side end portion 24, etc. For example, it can be manufactured from hard synthetic resin. Since this material is an elastic material, the idea of a snap fit is adopted to make the connecting portion 45 thicker and shorter to make the connecting portion 45 less likely to bend. It adheres strongly and can withstand a large repulsive force. A hard synthetic resin has a relatively larger elastic modulus than the material of the elastic protrusions 42 .

The elastic convex portion 42 of the retaining structure 210 may be made of an elastic, viscoelastic, sticky, soft, tacky synthetic resin material, or the like. The indicator main body 220 including the retainer structure 210 may be manufactured by extrusion molding together with the elastic projections 42 and other remaining portions.

In the connecting portion 45, (p16) the first connecting portion 46 connected to the base end portion 31 is closer to the outer convex portion 32 (to the right in FIG. 13, closer to the first inner surface 11) than the connecting portion 35 connected to the connecting portion 15. and (q16) the second connecting portion 47 is positioned inward of the groove 7 from the first connecting portion 46 in the depth direction. (lower part of FIG. 13), the position approaches the second inner surface 12 (thus, diagonally to the lower left part of FIG. 13), and the connecting part 45 is moved diagonally in the groove 7 to the lower left part of FIG. , can be arranged to extend over as long a distance as possible. As a result, when a product or the like collides with the force applying portion 221, a clockwise moment in FIG. Therefore, the elastic convex portion 42 is pressed against the first inner surface 11 to maximize the amount of deformation thereof, thereby increasing the contact area with the first inner surface 11 and increasing the friction between the elastic convex portion 42 and the first inner surface 11 . With increased force, it becomes even more reliable to prevent the legs 30 from leaving the grooves 7 .

The outer convex portion 32 extends outward in the depth direction of the groove 7 (upward in FIG. 13) as it approaches the first inner surface 11 (rightward in FIG. 13), that is, extends obliquely upward to the right in FIG. Its tip is formed at an acute angle. The inner convex portion 43 extends outward in the depth direction of the groove 7 (upward in FIG. 13) as it approaches the second inner surface 12, that is, extends diagonally to the upper left in FIG. Therefore, the outer convex portion 32 and the inner convex portion 43 function as claws that exhibit as large a force as possible to engage with the first and second inner surfaces 11 and 12 to prevent the leg portion 30 from coming off the groove 7. fulfill The elastic convex portion 42 is positioned closer to the inside (lower side in FIG. 13) in the depth direction of the groove 7 than the inner convex portion 43 is. The support protrusion 33 extends inward in the depth direction of the groove 7 (downward in FIG. 13) as it approaches the second inner surface 12 (leftward in FIG. 13).

The configuration of the side end portion 24 of the display device main body 220 will be described. The (p17) side end portion 24 continues to the end portion 26 on the groove 7 side (lower side in FIG. 13) of the support plate 205 of the force acting portion 221 of the display device main body 220, and is downstream of the force acting direction 206 (left side in FIG. 13). direction), it extends away from the groove 7 in the depth direction (upward in FIG. 13, and thus obliquely to the upper left in FIG. 13). (q17) The connection portion 15 approaches the first inner surface 11 from the downstream end portion 27 in the force acting direction 206 of the side end portion 24 toward the depth direction inner side of the groove 7 (lower side in FIG. 13) ( Therefore, it extends obliquely to the lower right in FIG. With these configurations (p17) and (q17), when a product or the like collides with the force acting portion 221 and a force acts on the end portion 26 to the left or upper left in FIG. A counterclockwise moment in FIG. 13 can be reliably generated. This moment ensures an increase in the frictional force with the first inner surface 11 due to the pressing deformation of the elastic convex portion 42 .

A first inclined guide surface 71 and a second inclined guide surface 72 are formed on the leg portion 30 . The first inclined guide surface 71 of the inner convex portion 43 extends outward in the depth direction of the groove 7 (upward in FIG. 13) as it approaches the second inner surface 12 (leftward in FIG. 13) from the connecting portion 47. As a whole, it extends smoothly (diagonally to the upper left in FIG. 13). The second inclined guide surface 72 of the connecting portion 45 smoothly extends from the first connecting portion 46 to the second connecting portion 47 away from the first inner surface 11 (diagonally to the lower left in FIG. 13).

Therefore, the leg portion 30 has a V shape in which the left-right spacing in FIG. 13 between the first inclined guide surface 71 and the second inclined guide surface 72 decreases toward the groove 7 (downward in FIG. 13). Therefore, as shown in FIG. 5 described above, the first inclined guide surface 71 and the second inclined guide surface 72 are brought into contact with the open ends 82 and 81 of the groove 7 to guide the leg portion 30 into the groove 7. The retaining structure 210 which is easy to insert and has good construction workability is realized. When the fitting operation is performed, the elastic projection 42 can be elastically compressed and deformed by coming into contact with the first inner surface 11 or the like, so there is no hindrance to the installation work.

The embodiment of FIG. 14 is similar to FIGS. 12 and 13 described above, but it should be noted that the side ends 24 and support pieces 204 of FIGS. 205 acts as a force acting portion that receives impact force from a product or the like, and the support plate 205 of FIG. Connected. Other configurations and actions are the same as those of the embodiment shown in FIGS. 12 and 13 described above.

The retainer structure of the present invention can be applied not only to product display shelves, but also to a wide range of other technical fields, such as a structure in which legs are fitted into grooves and hung.

FIG. 15 is a horizontal sectional view showing part of a door stop 19 in another embodiment of the invention. It should be noted that the cushioning piece 77 provided on the first side portion 21 of the doorstop body 20 is located at a position away from the vertical frame 2 (upper in FIG. 12) instead of the hollow cushioning piece 76 described above. It may be formed in the shape of a fin or a fin that is fixed to one side portion 21 and extends toward the vertical frame 2 (downward in FIG. 12), or may be of any other shape.

Therefore, when the door 5 impacts the first side 21, the moment clockwise 38 in FIG. By increasing the frictional force between the second inner protrusion 62 and the third inner surface 13 due to the force that presses the third inner surface 13 , it is possible to reliably prevent the second leg 50 from coming off the second groove 8 .

(3) The embodiment is

Extend. In addition, (q4) the second connecting portion 16 extends from the upstream end portion 29 of the second side end portion 25 in the closing movement direction 6 of the door 5 toward the depth direction inner side of the second groove 8 (lower side in FIG. 4). , it extends closer to the fourth inner surface 14 (thus, obliquely to the lower right in FIG. 4).

With these configurations (p4) and (q4), when the door 5 collides with the first side portion 21 and a force acts on the end portion 28 of the second side portion 22 in the lower right direction in FIG. The second outer convex portion 52 of the portion 51 is strongly pressed against the fourth inner surface 14, and the moment in the clockwise direction 38 in FIG. This moment increases the pressing force of the second inner convex portion 62 against the third inner surface 13, ensuring an increase in frictional force.

When the distance between the first inner convex portion 43 and the second inner convex portion 62 of the door stopper 10 in the natural state is W2, and the distance between the first outer convex portion 32 and the second outer convex portion 52 is W4, the following formula
W2 < W1 (1)
W3 < W4 (2)
is formed so that
In order to fit the first and second legs 30, 50 into the first and second grooves 7, 8 respectively, at least one of the first to fourth inclined guide surfaces 71 to 74 is 4 The door stop body 20 is moved to the first position while being in contact with the open ends 82, 81, 83, 84 of the second, first, third, and fourth inner surfaces 12, 11, 13, 14 facing the inclined guide surfaces 71-74. and the second grooves 7 and 8 are pushed inward in the depth direction.

(6) The embodiments shown in FIGS.
(g) the second leg 130
(g1) A second base end portion 131 connected to the doorstop main body 20 via a second connection portion 116,
a second outer protrusion 132 extending upstream in the closing movement direction 6 and facing the third inner surface 13;
a second support protrusion 133 extending downstream in the closing movement direction 6 and facing the fourth inner surface 14 on the downstream side of the second groove 8,
Within the second groove 8, the distance W133 (FIG. 9) between the end of the second outer protrusion 132 facing the third inner surface 13 and the end of the second support protrusion 133 facing the fourth inner surface 14 is the second a second base end portion 131 that is less than the width W8 of the groove 8 (that is, W133<W8);
(g2) The second distal end portion 141 arranged deeper in the depth direction of the second groove 8 than the second proximal end portion 131,
a second elastic projection 142 extending upstream in the closing movement direction 6 and elastically contacting the third inner surface 13;
a second tip portion 141 extending downstream in the closing movement direction 6 and having a second inner convex portion 143 facing the fourth inner surface 14;
(g3) having a second connecting portion 145 connecting the second proximal end portion 131 and the second distal end portion 141;
(h) When the door 5 does not collide with the first side portion 21, the second outer convex portion 132 and the second elastic convex portion 142 contact the third inner surface 13, and the second inner convex portion 143 contacts the fourth inner surface 14. spontaneously abut each other,
When the door 5 collides with the first side portion 21 , the second support projection 133 is characterized by coming into contact with the fourth inner surface 14 .

The configuration and operation of the second leg 130 are the same as or similar to those of the first leg 30 described above.

According to the sixth embodiment, referring to FIGS. 7 to 10 described later, the impact force of the door 5 on the first side portion 21 of the doorstop main body 20 is applied from the top portion 23 through the second side portion 22. , further downstream in the closing direction of movement 6 (FIGS. 7, 9 to the right). Therefore, the second support protrusion 133 connected to the second connection portion 135 of the second proximal end portion 131 is pressed against the fourth inner surface 14 . Therefore, the frictional force between the second support protrusion 133 and the fourth inner surface 14 is generated and increased, and the second leg 130 is prevented from separating upward in FIG. 9 from the second groove 8 .

Furthermore, due to the action of this impact force, the second base end portion 131, and therefore the second connecting portion 145, rotates around the position of contact with the fourth inner surface 14 of the second supporting protrusion 133 as a fulcrum. (reference numeral 137 in the enlarged view of FIG. 9) occurs. Therefore, the second elastic convex portion 142 of the second distal end portion 141 is pressed and crushed by the third inner surface 13 and deformed, and the contact area with the third inner surface 13 increases. As a result, the frictional force between the second elastic convex portion 142 and the third inner surface 13 increases, preventing the second leg portion 130 from separating upward in FIG. 9 from the second groove 8 . In this way, the moment in the second leg 130 increases in response to the impact force with which the door 5 collides with the first side portion 21. Therefore, when the impact force is large, (p5) the second elastic convex portion 142 The contact area with the third inner surface 13 corresponding to the large amount of deformation of is further increased. Therefore, the frictional force between the second elastic convex portion 142 and the third inner surface 13 is increased, and the separation of the second leg portion 130 from the second groove 8 can be reliably prevented.

As a result, in Embodiment (6), the hard synthetic resin press-contact claw strongly pushes the inner wall of the groove and makes it difficult to separate from the groove of the door stopper only by the frictional force of being caught on the inner wall. Solve the problem of what is enough.

In the second groove 8, the second base end portion 131 has a distance W133 between the end of the second outer protrusion 132 facing the third inner surface 13 and the end of the second support protrusion 133 facing the fourth inner surface 14. is less than the width W8 of the second groove 8 (that is, W133<W8), the operation of fitting the second base end portion 131 into the second groove 8 is facilitated.

When the door 5 does not collide with the first side portion 21, the elastic force of the second elastic protrusion 142 with the third inner surface 13 causes the second outer protrusion 132 to move toward the third inner surface 13 and the second inner protrusion. The portions 143 resiliently contact the fourth inner surface 14 respectively. Therefore, the separation of the second leg portion 130 from the second groove 8 is reliably prevented. At this time, a slight gap Δ133 (=W133−W8) exists between the second support protrusion 133 and the fourth inner surface 14 . The door 5 moves to close and collides with the first side portion 21 of the door stop main body 20 , and the second support projection 133 of the second base end portion 131 resists the elastic force of the second elastic projection 142 and moves to the second position.
