Description

  The present invention relates to a door stop for an upward-sliding sliding door and an upward-sliding sliding door device provided with the door stop.

  In an upholstered sliding door that does not guide the lower part with a rail or the like, various devices have been made to prevent the swinging of the sliding door in the thickness direction that is perpendicular to the opening / closing direction of the sliding door. For example, in Patent Document 1, a guide groove is provided in the lower end surface of the sliding door along the opening / closing direction of the sliding door, and the leading end portion of the guide piece screwed to the side surface of the lower portion of the adjacent sliding door in this guide groove. A technique for preventing a plurality of top-sliding type sliding doors from swinging in the thickness direction by inserting a sliding door and connecting adjacent sliding doors is disclosed.

  Patent Document 2 discloses a technique for preventing the swinging of the sliding door when the sliding door is closed by disposing a magnet and a suction plate on the upper suspension sliding door and the frame, respectively. In this disclosed technology, when the upper suspension type sliding door is closed and the sliding door approaches the frame body, the magnet is attracted to the adsorption plate and protrudes, and the adsorption force causes the sliding door and the frame body to be fixed, thereby preventing the sliding door from swinging. ing.

Japanese Patent No. 4105715 JP 2003-278438 A

  However, in the technique disclosed in Patent Document 1, although a plurality of adjacent sliding doors are connected to each other, it is impossible to prevent a swing of the connected plurality of sliding doors as a whole. In addition, since the disclosed technology disclosed in Patent Document 1 has a complicated structure, the cost of the anti-sway mechanism becomes expensive, and the anti-sway of a single upper suspension type sliding door cannot be performed.

  The technique disclosed in Patent Document 2 is also complicated in structure and has a large number of parts, which not only increases the cost of the steady rest mechanism, but also closes the sliding door when the sliding door is closed. When a wall surface or a frame is not arranged at the position, it is not applicable and the installation target is limited. That is, when the sliding door is closed, it is not possible to prevent the swinging of a single upper suspension type sliding door that has nothing around. Further, according to the disclosed technique of Patent Document 2, when the sliding door is closed and the suction plate and the magnet are attracted, there is a possibility that a large impact sound is generated.

  Therefore, an object of the present invention is to provide a top and bottom door that can be fixed at the open / closed position while preventing the swinging of the suspension type sliding door, whether it is a place without a wall surface or a single sliding door. The object is to provide a suspension type sliding door device.

  According to the present invention, there is provided a door stop for an upholstered sliding door which has a guide groove for shaking at the lower end, and one end of the guide groove for shaking is opened in the end face. The door stop includes a base member for fixing the door stop to the floor surface, and a cover member fitted to the base member so as to cover the base member. The cover member has a flat contact surface on which the top end of the sliding sliding door comes into contact, and a convex formed integrally from the bottom of the cover member toward the top so as to protrude from the contact surface. It has a section. This ridge has a trapezoidal cross-sectional shape with a side surface inclined so as to become narrower as it moves away from the contact surface, and the ridge is in the opening of the guide groove for swinging of the upper suspension type sliding door. When invading, the inclined side surface is configured to come into contact with the inner wall of the guide groove for vibration prevention.

  When fixing the suspended sliding door to the door, the protruding portion of the cover member of the door is engaged in the guide groove for shaking that is open on the end of the door. Since this convex part becomes narrow as it leaves | separates from a contact surface, the protrusion front-end | tip becomes narrow, the sliding door shakes and the center of an opening part has shifted | deviated to the center of the convex part to some extent. Even if fitting is started. When the fitting is started, the ridge portion is guided in the guide groove for vibration while the inclined side surface is in contact with the inner wall of the guide groove for vibration prevention, and the chamfer surface of the sliding door contacts the contact surface. Guidance stops at that point. At that time, since the protruding base portion of the ridge portion is wide, the ridge portion and the opening of the sliding door fit firmly, and the sliding door is securely fixed at the open / closed position without swinging in the thickness direction. . By using the door stopper having such a configuration, it is possible to reliably fix the upper suspension type sliding door at the open / close position without swinging despite the simple structure. Moreover, it can be used even in places where there are no wall surfaces or even a single sliding door.

  The protruding tip of the ridge has a width smaller than the width of the opening of the guide groove for vibration prevention, and the protruding base on the contact surface side of the ridge has a width substantially equal to the width of the opening. Preferably it is. Since the protruding strip portion of the cover member per door has a trapezoidal cross-sectional shape having such a width, the protruding strip portion of the door stop easily enters the opening of the guide groove for swinging of the suspension type sliding door. When intruding, the protruding base portion of the ridge portion comes into contact with the inner wall of the guide groove for steadying and fits securely, so that steady steadying is performed. In addition, when the sliding door collides with the door stop, the edge of the opening slides on the inclined side surface of the ridge, so that the impact is absorbed and weakened.

  It is also preferable that the cover member has a non-through hole opened in the bottom surface, and the base member is fitted into the non-through hole and fixed to the cover member. Thereby, since a cover member and a base member are fixed only by fitting, attachment of a door stop becomes very easy.

  It is also preferable that the top end of the convex portion of the cover member is located below the top end of the contact surface. As a result, the end face of the upper suspension type sliding door also comes into contact with the portion of the contact surface located on the upper side of the ridge portion, so that the door contact area is increased.

  It is also preferable that the surface opposite to the contact surface of the cover member has a semi-elliptical sphere shape. Thus, by making the surface on the opposite side of the cover member a smooth shape, the safety when a foot or the like collides is increased, and the aesthetic appearance is also improved.

  It is also preferable that the cover member is made of a shock absorbing material. In this case, it is more preferable that the impact absorbing material of the cover member has a hardness of 15 to 90. By comprising with such an impact-absorbing material, the impact when a sliding door collides with a door stop is relieved.

  It is also preferable that the ratio of the width of the protruding base portion on the contact surface side in the convex portion to the width of the contact surface is in the range of 1/6 to 1. If the width of the contact surface is large, the impact between the sliding door's front end and the door stop is alleviated, and if the width of the ridge is large, the steady rest is effectively performed.

  It is also preferable that the end of the protruding portion on the top side is chamfered.

  According to the present invention, the upper suspension type sliding door device further includes an upper suspension type sliding door having an anti-vibration guide groove at a lower end, and one end of the anti-vibration guide groove being opened at the end of the mouth. And a sliding door. The door stop includes a base member for fixing the door stop to the floor surface and a cover member fitted to the base member so as to cover the base member. The cover member has a flat contact surface on which the top end of the sliding sliding door comes into contact, and a convex formed integrally from the bottom of the cover member toward the top so as to protrude from the contact surface. It has a section. This ridge has a trapezoidal cross-sectional shape with a side surface inclined so as to become narrower as it moves away from the contact surface, and the ridge is in the opening of the guide groove for swinging of the upper suspension type sliding door. The inclined side surface when invading is configured to abut against the inner wall of the guide groove for vibration prevention.

  When fixing the suspended sliding door to the door, the protruding portion of the cover member of the door is engaged in the guide groove for shaking that is open on the end of the door. Since this convex part becomes narrow as it leaves | separates from a contact surface, the protrusion front-end | tip becomes narrow, the sliding door shakes and the center of an opening part has shifted | deviated to the center of the convex part to some extent. Even if fitting is started. When the fitting is started, the ridge portion is guided in the guide groove for vibration while the inclined side surface is in contact with the inner wall of the guide groove for vibration prevention, and the chamfer surface of the sliding door contacts the contact surface. Guidance stops at that point. At that time, since the protruding base portion of the ridge portion is wide, the ridge portion and the opening of the sliding door fit firmly, and the sliding door is securely fixed at the open / closed position without swinging in the thickness direction. . According to the upper suspension type sliding door device having such a configuration, the upper suspension type sliding door can be reliably fixed at the open / closed position without swinging despite the simple structure. Moreover, it can be used even in places where there are no wall surfaces or even a single sliding door.

  The protruding tip of the ridge in the door stop has a width smaller than the width of the opening of the guide groove for vibration prevention, and the protruding base on the contact surface side of the ridge has a width substantially equal to the width of the opening. It is preferable to have. Since the protruding strip portion of the cover member per door has a trapezoidal cross-sectional shape having such a width, the protruding strip portion of the door stop easily enters the opening of the guide groove for swinging of the suspension type sliding door. When intruding, the protruding base portion of the ridge portion comes into contact with the inner wall of the guide groove for steadying and fits securely, so that steady steadying is performed. In addition, when the sliding door collides with the door stop, the edge of the opening slides on the inclined side surface of the ridge, so that the impact is absorbed and weakened.

  It is also preferable that the cover member at the door end has a non-through hole opened on the bottom surface, and the base member is fitted into the non-through hole and fixed to the cover member. Thereby, since a cover member and a base member are fixed only by fitting, attachment of a door stop becomes very easy.

  It is also preferable that the top end of the convex portion of the cover member in the door contact is located below the top end of the contact surface. As a result, the end face of the upper suspension type sliding door also comes into contact with the portion of the contact surface located on the upper side of the ridge portion, so that the door contact area is increased.

  It is also preferable that the surface opposite to the contact surface of the cover member in the door contact has a semi-elliptical sphere shape. Thus, by making the surface on the opposite side of the cover member a smooth shape, the safety when a foot or the like collides is increased, and the aesthetic appearance is also improved.

  It is also preferable that the cover member in the door contact is made of a shock absorbing material. By comprising with such an impact-absorbing material, the impact when a sliding door collides with a door stop is relieved.

  It is also preferable that the end portion on the top side of the protruding portion of the cover member in the door contact is chamfered.

  ADVANTAGE OF THE INVENTION According to this invention, although it is the door stop of a simple structure, an upper suspension type sliding door can be reliably fixed to an opening-and-closing position without swinging. Moreover, it can be used even in places where there are no wall surfaces or even a single sliding door.

  Hereinafter, the embodiment of FIG. 1 will be described in detail with reference to these drawings.

  The upper suspension type sliding door device according to the present embodiment basically includes a plurality of upper suspension type sliding doors 10 and at least one door stop 11. Each upper suspension type sliding door 10 is suspended from an upper rail 12 via a runner (not shown), and is configured to travel along the upper rail 12. The lower end of the sliding door 10 is not fixed to the floor surface 13 and is a free end.

  On the other hand, the bottom of the door stop 11 is fixed to the floor surface 13, and when the sliding door 10 is closed, the opening on the side of the mouth end 10 b of the guide groove 10 a for anti-vibration provided at the lower end of the sliding door 10. It is comprised so that it can fit in 10c.

  As can be seen from FIG. 2, the door stop 11 includes a cover member 14 integrally formed of a shock-absorbing material, and a base member 15 for fixing the door stop 11 to the floor surface 13.

  The cover member 14 is formed by integrally molding with a shock absorbing material. The shock-absorbing material may be any material that has elasticity and flexibility and has a property of absorbing an applied force. For example, soft plastic or rubber is used. The hardness is preferably about 15 to 90. In the present embodiment, a synthetic rubber having a hardness of 40 is used as the cover member 14. By configuring the cover member 14 with such a shock-absorbing material, the impact when the sliding door 10 collides with the door stop 11 is reduced.

  When the sliding door 10 is closed, the cover member 14 has a flat contact surface 14a for contacting the lower part of the wood end surface 10b of the sliding door 10 and the horizontal direction of the contact surface 14a (y in FIG. 2). And a protruding strip portion 14b protruding from the central portion in the axial direction and the thickness direction of the sliding door 10). The surface 14c opposite to the contact surface 14a of the cover member 14 has a semi-elliptical sphere shape. Thus, by making the surface 14c on the opposite side of the cover member 14 into a smooth shape, safety when a foot or the like collides is increased, and aesthetics are also improved.

When the sliding door 10 is closed, the protruding strip portion 14b is a portion that fits into the opening 10c on the wooden face 10b side of the guide groove 10a for vibration prevention provided at the lower end of the sliding door 10, and this cover member 14 extends from the bottom to the top (in the z-axis direction in FIG. 2, the height direction of the sliding door 10). However, the top end 14b ₁ of the convex portion 14b is positioned below the top end 14a ₁ of the contact surface 14a. Thereby, the area of the contact surface 14a which the wooden door surface 10b of the sliding door 10 contacts increases, and the impact absorbability when the sliding door 10 collides can be further improved.

Ridge 14b includes has a trapezoidal cross-sectional shape, the side surface 14b ₂ which is inclined in a tapered shape so as to be narrow with increasing distance from the contact surface 14a on both sides thereof. Therefore, as shown in FIG. 2, the width W _T (the length in the y-axis direction in FIG. 2) of the protruding tip 14b ₃ of the ridge 14b is the width W _B of the protruding base 14b ₄ on the contact surface 14a side. It is narrower than (the length in the y-axis direction in FIG. 2). In the present embodiment, the ratio W _T / W _B between the two is substantially W _T / W _B = 1/2. _However, W T / _{W B} may be 1 / 3-2 / 3.

Here, the width _{W T} of the protruding end 14b ₃ of ridges 14b can have a width less than the width of the opening 10c of Futome guiding groove 10a of the sliding door 10, the abutment surface of the convex portion 14b it is desirable that the width _{W B} of 14a of side projecting base portion 14b ₄ has a width approximately equal to the width of the opening 10c. Since the protruding strip portion 14b of the cover member 14 has a trapezoidal cross-sectional shape with such a width, the protruding strip portion 14b can easily enter the opening portion 10c of the guide groove 10a for swinging of the sliding door 10, and the intrusion when the protruding base portion 14b ₄ of the convex portion 14b abuts against the inner wall of Futome guiding groove 10a, so tightly fits, slide stop is ensured. Moreover, when the collision sliding door 10, since the end edge of the opening 10c slides inclined side surface 14b ₂ on the convex portion 14b, weakened impact is absorbed by that portion.

Further, the width W _B of the protruding base portion 14b ₄ of the ridge portion 14b is set to be equal to or less than the width W _S of the contact surface 14a (the length in the y-axis direction in FIG. 2). For _example, it is desirable W B / _{W S} is 1 / 6-1, 1 / 3-1 / 2 is more preferable. In this embodiment, W _B / W _S = 1 / 2.4. Impact of the width W _S is as large as the sliding door 10 and the doorstop 11 of the abutment surface 14a can be more effectively absorbed. If the width W _B of the projection base portion 14b ₄ of the convex portion 14b is large, the inclination angle can be corrected be inclined during the fitting increases, vibration is stopped is effectively carried out, is too large the fitting itself is difficult Thus, since the area of the contact surface 14a is reduced, the impact at the time of collision between the end face 10b and the door stop 11 is hardly absorbed.

On the other hand, the base member 15 of the door stop 11 is made of a hard metal material such as steel in order to obtain sufficient mounting strength. In this embodiment, the base member 15 is formed by press-molding a steel plate. As shown in FIG. 2, the base member 15 is bent vertically from a bottom plate portion 15a, a vertical plate portion 15b bent vertically from the bottom plate portion 15a, and a side end of the vertical plate portion 15b. and a side plate portion 15c and 15d, 3 single screw hole 15b ₁ for wood screws 16 are drilled in the vertical plate portion 15b. In order to fix the base member 15 to the floor surface 13, the wood screw 16 may be screwed to the floor surface 13 through these screwing holes 15 b ₁ .

  As shown in FIG. 3, a non-through hole 14e is opened on the bottom surface 14d of the cover member 14, and the cover member 14 is fixed to the base member 15 by fitting the base member 15 into the non-through hole 14e. Is configured to do. Thus, since the cover member 14 and the base member 15 are fixed only by fitting, it is very easy to attach the door stop 11 to the floor surface.

More specifically, in the non-through hole 14e of the cover member 14, when the base member 15 is fitted, a shallow recess 14f that receives the bottom plate portion 15a and a standing plate that tightly receives the standing plate portion 15b. A groove portion 14g and side plate groove portions 14h and 14i for receiving the side plate portions 15c and 15d, respectively, are formed. The standing plate groove portion 14g and the side plate groove portions 14h and 14i constitute a receiving groove that is substantially U-shaped when the cover member 14 is viewed from the bottom surface side. The standing plate groove portion 14g is formed in parallel with the contact surface 14a, and has substantially the same depth as the height (the length in the z-axis direction) of the standing plate portion 15b of the base member 15. Deepest 14 g ₁ of the width of the upright plate grooves 14 g, or gap (length in the x-axis direction), to the extent that can be fixed by gripping its tip when standing portion 15b is pushed, upright groove It is slightly shorter than other parts of 14g. The depth (length in the z-axis direction) of the side plate groove portions 14h and 14i is shallower than the depth (length in the z-axis direction) of the standing plate groove portion 14g. Further, the length (length in the x-axis direction) of the side plate groove portions 14h and 14i is substantially equal to the width (length in the x-axis direction) of the side plate portions 15c and 15d. The shallow concave portion 14 f has a space for accommodating the bottom plate portion 15 a and the wood screw 16 when the base member 15 is fitted.

In order to fix the cover member 14 to the base member 15, the standing plate portion 15b of the base member 15 is inserted into the standing plate groove portion 14g, and the side plate portions 15c and 15d of the base member 15 are inserted and pushed into the side plate groove portions 14h and 14i, respectively. Thus, the fitting is finally performed. As shown in FIG. 4, for clearance deepest 15 g ₁ of the upright plate groove 14g is shorter than the thickness of the upright plate portion 15b, the elasticity of the upper portion of the upright plate portion 15b is of synthetic rubber which is the material of the cover member 14 It is sandwiched and held and fixed. In addition, since the lengths of the side plate groove portions 14h and 14i (length in the x-axis direction) are substantially equal to the widths of the side plate portions 15c and 15d (length in the x-axis direction), the side plate portions 15c and 15d constitute the cover member 14. It is gripped and fixed by the elasticity of the synthetic rubber material.

  In order to attach the door stop 11 of the present embodiment to the floor surface 13, first, the base member 15 is screwed to the floor surface 13 with the wood screw 16, and the non-through hole 14 e of the cover member 14 is formed on the base member 15. By inserting and pushing, it is fitted and fixed as shown in FIG.

  As shown in FIG. 5, a swing guide groove 10 a is formed at the lower end of the upper suspension type sliding door 10 over the entire length along the opening / closing direction of the sliding door 10 (the x-axis direction in FIG. 5). One end of the guide groove for abutment 10a opens to the wooden face 10b of the sliding door 10 to form an opening 10c. The height (the length in the z-axis direction) of the ridge 14b in the cover member 14 of the door stop 11 is set to be substantially equal to the depth of the guide groove 10a for stabilization. Although not shown in the drawings, it is desirable to provide an anti-vibration mechanism for suppressing the shake of the sliding door 10 in the thickness direction (y-axis direction) between the anti-vibration guide grooves 10 a of the adjacent sliding doors 10.

  Next, the operation | movement which the upper suspension type sliding door 10 of this embodiment is fixed to the door stop 11 is demonstrated.

When the sliding door 10 is closed, the protruding strip portion 14b of the cover member 14 of the door stopper 11 fixed to the floor surface is engaged in the guide groove 10a for shaking that is open on the wooden face 10b of the sliding door 10. Since the convex portion 14b is configured such that the width direction away from the contact surface 14a is narrowed, the protruding end 14b ₃ is a narrow width, thus, as shown by the solid line in FIG. 6, the sliding door 10 even if the thickness direction center 10c ₁ of the shake the opening 10c (y-axis direction in FIG. 5) is somewhat deviated from the center 14b ₅ ridge portions 14b of the doorstop 11, fitting start Is done. When fitting is started, ridges 14b, the inclined side surfaces 14b ₂ is guided in contact with the Futome guiding groove 10a in the edge of the opening 10c, while being displaced by the vibration is corrected, When the wooden face 10b of the sliding door 10 contacts the contact surface 14a of the door stop 11, the guidance stops. At this time, the relative position of the door stopper 11 to the sliding door 10 is a position indicated by a two-dot chain line in FIG. When the sliding door 10 swings, actually, as shown in FIG. 7, the sliding door 10 is inclined by an angle α _{1 with} respect to an axis perpendicular to the floor surface (z axis in FIG. 5). Again, the corners of the inclined with side 14b ₂ and the protruding tip 14b ₃ and apical 14a ₁ of the convex portion 14b is guided in contact with Futome guiding groove 10a in the edge of the opening 10c.

Since the projecting base portion 14b ₃ of the convex portion 14b of the doorstop 11 has a larger width, the opening 10c and is firmly fitted in the convex portion 14b and the sliding door 10, sliding door 10 swings in the thickness direction thereof It is securely fixed in the open / close position without any problems. In other words, a state where the center 14b ₅ ridge portions 14b of the center 10c ₁ and doorstop 11 of the opening 10c of the sliding door 10 is fitted to match. This state is shown in FIGS.

  As shown in FIG. 9, the vertical depth of the guide groove 10 a for locking the sliding door 10 is substantially equal to the height of the protruding strip portion 14 b of the door stopper 11, but between the sliding door 10 and the floor surface 13. Since the gap d exists, the ridge 14b is fitted into the guide groove 10a for vibration prevention with a margin of the gap d in the vertical direction.

  When closing the sliding door 10, in most cases, the wooden face 10 b of the sliding door 10 collides with the contact surface 14 a of the cover member 14 in the door stop 11. At the time of this collision, the sliding surface 10 b and the abutment surface 14 a of the door stop 11 come into contact with each other, which makes it impossible for the swing guide groove 10 a of the sliding door 10 and the protruding strip 14 b of the door stop 11. The force is not damaged by being applied, and the force is dispersed and relaxed by the wide area of the contact surface 14a. Further, since the entire cover member 14 is formed of a shock-absorbing material, it is possible to absorb the impact of the collision and reduce the impact sound, and also prevent both the sliding door 10 and the door stop 11 from being damaged.

  Further, since the upright plate portion 15b of the base member 15 is arranged behind the abutment surface 14a of the cover member 14 and in parallel with the abutment surface 14a, the impact is evenly transmitted to the entire surface of the upright plate portion 15b. Since the bias is not applied to a part of the member 15, damage is hardly caused to the fixing portion of the base member 15 to the floor surface.

  Further, since the cover member 14 has a semi-elliptical spherical shape on the back surface 14c opposite to the contact surface 14a, the shock is absorbed by the impact on the contact surface 14a being transferred to the curved surface and evenly released. More effective. Furthermore, since the cover member 14 is formed of a shock-absorbing material and the back surface 14c has a smooth shape, safety when there is a collision with an object other than a sliding door or a person is increased. , Aesthetics will also improve.

As described above, according to the present embodiment, when the upper suspension type sliding door 10 is fixed to the door stop 11, the cover member 14 of the door stop 11 is placed in the guide groove 10a for swinging that is open on the end face 10b. While engaged causes the convex portions 14b of, since the convex portion 14b is a narrow with increasing distance from the contact surface 14a, the projecting tip 14b ₃ is a narrow, swings sliding door 10 The fitting is started even if the center of the opening 10c is shifted to some extent from the center of the ridge 14b. When the fitting is started, the ridge portion 14b is guided into the anti-vibration guide groove 10a while the inclined side surface 14b ₂ abuts against the inner wall of the anti-vibration guide groove 10a, and the sliding end 10's wooden face 10b. Guidance stops when the abutment abuts against the abutment surface 14a. The projecting base portion 14b ₄ of the convex portion 14b is in the wide, and the opening 10c of the convex portion 14b and the sliding door 10 is securely fitted, the sliding door 10 is reliably opened and closed position without swinging in the thickness direction Fixed to. By using the door stopper 11 having such a configuration, it is possible to reliably fix the upper suspension type sliding door 10 at the open / close position without swinging despite the simple structure. Moreover, it can be used even in places where there are no wall surfaces or even a single sliding door.

  FIG. 10 is a perspective view showing in detail the structure of a door stop according to another embodiment of the present invention, and FIG. 11 is a side view showing the relationship between the door stop and the sliding door of this embodiment when the sliding door swings. . In the present embodiment, the shape of the cover member 114 of the door stop 111 is different from that of the embodiment of FIG. 1, but other configurations are the same as those of the embodiment of FIG. Therefore, in the present embodiment, the same components as those in the embodiment of FIG. 1 will be described using the same reference numerals.

  In the present embodiment, the door stop 111 includes a cover member 114 integrally formed of a shock-absorbing material, and a base member (not shown) for fixing the door stop 111 to the floor surface. The structure of this base member is the same as that of the embodiment of FIG.

  The cover member 114 is integrally formed of a shock absorbing material. The shock-absorbing material may be any material that has elasticity and flexibility and has a property of absorbing an applied force. For example, soft plastic or rubber is used. The hardness is preferably about 15 to 90. In this embodiment, a synthetic rubber having a hardness of 40 is used. By configuring the cover member 114 with such an impact-absorbing material, the impact when the sliding door 10 collides with the door stop 111 is reduced.

  When the sliding door 10 is closed, the cover member 114 has a flat contact surface 114a for contacting the lower part of the wood end surface 10b of the sliding door 10 and the left and right direction of the contact surface 114a (y in FIG. 10). And a protruding strip portion 114b protruding from the central portion in the axial direction and the thickness direction of the sliding door 10). A surface 114c of the cover member 114 opposite to the contact surface 114a has a semi-elliptical sphere shape. Thus, by making the surface 114c on the opposite side of the cover member 114 into a smooth shape, safety when a foot or the like collides is increased, and aesthetics are also improved.

When the sliding door 10 is closed, the ridge 114b is a portion that fits into the opening 10c on the wooden face 10b side of the guide groove 10a for vibration prevention provided at the lower end of the sliding door 10, and this cover member It extends from the bottom of 114 toward the top (the z-axis direction in FIG. 10, the height direction of the sliding door 10). However, the top end 114b ₁ of the convex portion 114b is located lower than the top end 114a ₁ of the abutting surface 114a. Thereby, the area of the contact surface 114a which the wooden door surface 10b of the sliding door 10 contacts increases, and the impact property at the time of the sliding door 10 colliding can be improved more.

Ridges 114b are provided has a trapezoidal cross-sectional shape, the side surface 114b ₂ which is inclined in a tapered shape so as to be narrow with increasing distance from the contact surface 114a on both sides. Therefore, as shown in FIG. 10, the width W _T ′ (the length in the y-axis direction in FIG. 10) of the protruding tip 114b ₃ of the ridge 114b is the width W of the protruding base 114b ₄ on the contact surface 114a side. It is narrower than _B ′ (the length in the y-axis direction in FIG. 10). In the present embodiment, the ratio of the widths W _T ′ / W _B ′ is W _T ′ / W _B ′ = 1/2. However, W _T '/ W _B ' may be 1/3 to 2/3.

Here, the width W _T ′ of the projecting tip 114b ₃ at the lower part of the ridge 114b (in the negative z-axis direction in FIG. 10) has a width smaller than the width of the opening 10c of the guide groove 10a for swinging of the sliding door 10. It is desirable that the width W _B ′ of the protruding base 114b ₄ on the abutment surface 114a side of the protrusion 114b is substantially equal to the width of the opening 10c. Since the protruding strip portion 114b of the cover member 114 has a trapezoidal cross-sectional shape having such a width, the protruding strip portion 114b can easily enter the opening portion 10c of the guide groove 10a for swinging of the sliding door 10. When this occurs, the protruding base 114b ₄ of the ridge 114b comes into contact with the inner wall of the guide groove 10a for steadying and is firmly fitted, so that steady steadying is performed. Moreover, when the collision sliding door 10, since the end edge of the opening 10c slides inclined side surface 114b ₂ above the convex portion 114b, weakened impact is absorbed by that portion.

Further, the width W _B ′ of the protruding base 114b ₄ of the ridge 114b is set to be equal to or smaller than the width W _S ′ (the length in the y-axis direction in FIG. 10) of the contact surface 114a. For _example, it is desirable _W B '/ W _S' is 1 / 6-1, 1 / 3-1 / 2 is more preferable. In the present embodiment, W _B '/ W _S ' = 1 / 2.4. When the width W _S ′ of the contact surface 114a is large, the impact between the sliding door 10 and the door stop 111 is more effectively absorbed. If the width W _B ′ of the protruding base 114b ₄ of the ridge 114b is large, the inclination angle that can be corrected even if it is inclined at the time of fitting is increased, and the steadying is effectively performed. It becomes difficult and the area of the contact surface 114a becomes small, so that it is difficult to absorb the impact at the time of collision between the end face 10b and the door stop 111.

In the present embodiment, in particular, the corners of the side surface 114b ₂ , the projecting tip 114b _3, and the top end 114b ₁ in the upper portion (the z-axis positive direction in FIG. 10) of the protruding portion 114b of the cover member 114 are chamfered and the chamfered inclined portion. 114b ₅ is formed. For this reason, with respect to the width W _T ′ of the protruding tip 114b ₃ at the lower part (the z-axis negative direction in FIG. 10) of the protruding part 114b, the protruding tip at the upper part (the z-axis positive direction in FIG. 10) of the protruding part 114b. The width W _TS ′ of 114b ₃ is narrowed. For example, in this embodiment, W _TS ′ / W _T ′ = 1/2.

As described above, the chamfered inclined portion 114b ₅ is provided on the upper portion of the protruding portion 114b of the door stop 111, and the width thereof is narrow, so that the sliding door 10 is an axis perpendicular to the floor surface 13 (z axis in FIG. 10). respect, even when the greatly inclined angle alpha _2, chamfered inclined portion 114b ₅ ridge portions 114b are guided to Futome guiding groove 10a while in contact with the edge of the opening 10c, the fitting You can start. Even when the swing of the sliding door 10 is smaller, the upper portion of the protruding portion 114b does not collide with the end face 10b, so that the protruding portion 114b is likely to smoothly enter the steadying guide groove 10a. Of course, to increase the area of the chamfered inclined portion 114b _5, if thinner the top of the convex portion 114b, the ridges 114b are easily penetrated by Futome guiding groove 10a. When the width W _TS ′ of the upper portion of the ridge 114b becomes extremely narrow, so that the ridge 114b may bite into the end face 10b, or when this portion collides with a person or an object other than the sliding door, The upper width W _TS ′ is preferably 1/2 ≦ W _TS ′ / W _T ′ <1 with respect to the lower width W _T ′. In addition, if the area of the chamfered inclined portion 114b ₅ is too large, the protruding portion 114b is fitted into the guide groove 10a for vibration prevention, and the vibration preventing action is weakened. Therefore, the vertical direction of the chamfered inclined portion 114b ₅ (z in FIG. 10). The length in the axial direction) is preferably less than 1/3 of the entire length of the ridge 114b. Even if the area of the chamfered inclined portion 114b ₅ is small, the above-described effect can be obtained even if the inclined portion is not a flat surface, and the chamfered inclined portion 114b5 may be rounded and chamfered.

As described above, according to the present embodiment, when the upper suspension type sliding door 10 is fixed to the door stop 111, the cover member 114 of the door stop 111 is placed in the guide groove 10a for swinging that is open on the end face 10b. While engaged causes the convex portion 114b of, since the convex portion 114b is in the narrow direction away from the contact surface 114a, the protruding end 114b ₃ is a narrow, swings sliding door 10 The fitting is started even if the center of the opening 10c is shifted to some extent from the center of the ridge 114b. In particular, in this embodiment, since the chamfered inclined portion 114b ₅ is provided on the upper portion of the protruding portion 114b and the width of the portion is narrower, even when the sliding door 10 is greatly inclined, the protruding portion 114b The chamfered inclined portion 114b ₅ is guided into the anti-vibration guide groove 10a while being in contact with the edge of the opening 10c, so that fitting can be started. When the fitting is started, the ridge portion 114b is guided into the guide groove 10a for anti-vibration while the inclined side surface 114b ₂ abuts against the inner wall of the guide groove 10a for anti-vibration, and the wooden face 10b of the sliding door 10 is obtained. Guidance stops when the abutment comes into contact with the abutment surface 114a. The projecting base portion 114b ₄ ridge portions 114b has become wider, and the opening 10c of the convex portion 114b and the sliding door 10 is securely fitted, the sliding door 10 is reliably opened and closed position without swinging in the thickness direction Fixed to. By using the door stopper 111 having such a configuration, it is possible to reliably fix the upper suspension type sliding door 10 at the open / close position without swinging despite the simple structure. Moreover, it can be used even in places where there are no wall surfaces or even a single sliding door.

  In the above-described embodiment, an impact absorbing material may be applied on the inner wall of the guide groove 10a for vibration prevention. Thereby, the impact at the time of fitting with the sliding door 10 and the door stop 111 is absorbed. When the shock-absorbing material applied to the inner wall of the guide groove 10a for vibration prevention and the shock-absorbing material of the cover member 114 of the door stop 111 are made of a shock-absorbing material having a high friction coefficient, for example, rubber, contact The frictional force between the surfaces of the cover member 114 and the guide groove 10a for vibration prevention is increased, and the impact absorption effect and the vibration prevention effect can be further improved.
