  Arrows or the like indicating the directions given to the respective drawings are provided to facilitate understanding of the relationship between the respective drawings. The present invention is not limited to the directions given in the respective drawings. At least one member or part described with at least the reference numeral is provided except in the case where “plurality”, “two or more”, etc. are described.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First Embodiment
The door stopper apparatus 1 which concerns on this embodiment is mounted | worn with the inside plane part of a door, as shown to Fig.1 (a). The inner flat portion of the door means a plate surface or the like facing the traveling direction side of the door when the open door is displaced in the closing direction.

1. Overview of Door Stopper As shown in FIG. 2A, the door stopper 1 includes at least a base 3, a stick arm 5, a handle 7, a transmission mechanism 9, and the like. The base portion 3 is a portion fixed directly or indirectly to the inner flat portion of the door.

  In addition, the base part 3 which concerns on this embodiment is fixed to a door via the guide base 11 shown in FIG.1 (b), and permanent magnet 13A, 13B shown in FIG.2 (b). The guide base 11 is a member of a band plate assembled to the base 3 by a screw, and a double-sided adhesive tape is attached to a portion facing the door.

  The guide base 11 is made of metal and is detachably mounted on a resin base 3 by mechanical fastening means such as screws. Then, the user can select the mounting position of the guide base 11 to the base 3 (hereinafter referred to as the mounting position of the guide base 11) from among a plurality of positions.

  That is, as shown in FIG. 1B, at one end side in the longitudinal direction of the guide base 11, a positioning end face 11A erected in a direction perpendicular to the strip-like plate surface is provided. The user can determine the mounting height of the door stopper device 1 with respect to the door by attaching the door stopper device 1 to the door in a state where the positioning end surface 11A is in contact with the lower end surface of the door.

  The above-mentioned “plurality of positions” is a position where the positioning end face 11A is separated from the base portion 3 (see FIG. 2A) and a position where the positioning end face 11A is close to the base portion 3 (FIG. )) Is set between. Then, the user can attach the door stopper device 1 to the door by selecting a position suitable for the user from the “plurality of positions”.

  The stick arm 5 is a member assembled so as to be displaceable with respect to the base 3. Specifically, the stick arm 5 is displaced between a first position indicated by a solid line in FIG. 1 (b) and a second position indicated by a two-dot chain line in FIG. 1 (b).

  The first position is a position where the tip of the stick arm 5 contacts the floor to hold the door open. A non-slip boot 5A made of a material having a large coefficient of friction, such as rubber, is provided at the tip of the stick arm 5.

  The second position is a position where the tip of the stick arm 5 is separated from the floor. Then, the stick arm 5 according to the present embodiment swings and displaces with respect to the base portion 3 between the first position and the second position.

  The handle portion 7 is a portion operated by the user. The said handle part 7 is a position separated from the base part 3 as shown in FIG.1 (b). When the door stopper device 1 is attached to the door, the handle portion 7 is positioned above the stick arm 5.

  The transmission mechanism 9 transmits the operation of the user input to the handle portion 7 to the stick arm 5. That is, the handle portion 7 is operated by the user to the third position (the position shown by the solid line in FIG. 1B) and the fourth position (see FIG. 1) separated from the base portion 3 from the third position. It is displaceable with respect to the position shown with the dashed-two dotted line of (b).

  Then, the transmission mechanism 9 sets the stick arm 5 to the first position when the handle portion 7 is at the third position, and sets the stick arm 5 to the second position when the handle portion 7 is at the fourth position.

  Specifically, when the handle portion 7 is at a position (fourth position) higher than the third position, the transmission mechanism 9 displaces the stick arm 5 upward to separate the stick arm 5 from the floor.

  Then, when the handle portion 7 is at a lower position (third position) than the fourth position, the transmission mechanism 9 displaces the stick arm 5 downward to move the tip of the stick arm 5, that is, the non-slip boot 5A. Contact the floor.

2. Configuration of Transmission Mechanism and its Operation Etc. As shown in FIG. 1B, the handle portion 7 can be displaced in parallel between the third position and the fourth position. That is, in the state in which the door stopper device 1 is attached to the door, the handle portion 7 can be displaced in parallel in the vertical direction.

  Then, as shown in FIG. 3A, the transmission mechanism 9 transmits the operation input to the handle portion 7 to the stick arm 5 using the reciprocating slider crank mechanism. That is, the reciprocating slider crank mechanism converts the parallel motion of the handle portion 7 into a swing motion and transmits the operation of the handle portion 7 to the stick arm 5.

  As shown in FIG. 3B, the reciprocating slider crank mechanism, that is, the transmission mechanism 9 is configured to have an operation frame 9A, a slide pin 9C, and the like. The actuation frame 9A is a member which is displaceable with respect to the base portion 3 and is displaced in parallel with the handle portion 7 integrally. As shown in FIG. 4A, the actuating frame 9A is provided with an elongated hole 9B extending in a direction perpendicular to the displacement direction of the actuating frame 9A.

  The displacement direction of the actuation frame 9A coincides with the vertical direction when the door stopper device 1 is attached to the door. Hereinafter, the displacement direction of the operation frame 9A, that is, the displacement direction of the handle portion 7 is referred to as the vertical direction, and the direction orthogonal to the vertical direction is referred to as the horizontal direction.

  The handle portion 7 and the actuation frame 9A are connected via a rod 9D as shown in FIG. 3 (a). The rod member 9D is a rod-like rigid body extending in the longitudinal direction. One longitudinal end of the rod member 9D is fixed to the handle 7 by a nut 9E, and the other end is locked to the actuating frame 9A by a snap ring 9F.

  As shown in FIG. 4 (b), the operation frame 9A is provided with a stepped insertion hole 9G into which the other end side in the longitudinal direction of the rod member 9D is inserted. Further, the other end side in the longitudinal direction of the rod material 9D is also a stepped shape similar to the shape of the insertion hole 9G.

  As a result, the actuating frame 9A is sandwiched between the retaining ring 9F and the step portion of the rod 9D, so the rod 9D and the actuating frame 9A are integrated. Therefore, the handle portion 7 and the actuation frame 9A integrally move vertically in the vertical direction.

  As shown in FIG. 4 (c), sliding contact (hereinafter referred to as “following” to the guide groove 3A (see FIG. 5 (a)) provided on the base 3 is made on the portion of the actuating frame 9A facing the base 3. , Sliding or sliding contact) is provided. The guide groove 3A extends in the longitudinal direction as shown in FIG. 5 (b).

  As shown in FIGS. 6A and 6B, the slide pin 9C is a member provided at a position shifted from the swing center O1 of the stick arm 5, and the swing pin 9C swings the stick arm 5. It is formed in a cylindrical or cylindrical shape having an axis parallel to the center line L1.

  Then, as shown in FIGS. 3 (a) and 3 (b), the slide pin 9C displaces the inside of the elongated hole 9B provided in the actuation frame 9A in the major axis direction. That is, the slide pin 9C is laterally displaced in the long hole 9B while performing a circular motion centering on the swing center O1. On the other hand, the actuating frame 9A is displaced in the longitudinal direction in conjunction with the circular movement of the slide pin 9C.

  Therefore, when the actuating frame 9A, that is, the handle portion 7 is displaced in the longitudinal direction, the slide pin 9C circularly moves as the swing center O1 in conjunction with this, so the stick arm 5 is interlocked with the vertical movement of the handle portion 7. Also swing up and down.

  The center position O2 of the slide pin 9C is always shifted in the lateral direction with respect to the imaginary line Lo regardless of the position of the stick arm 5. A virtual line Lo is a virtual line passing through the rocking center O1 of the stick arm 5 and parallel to the longitudinal direction.

  The lateral displacement amount W1 of the slide pin 9C at the first position (see FIG. 3A) is the lateral displacement amount W2 of the slide pin 9C at the second position (see FIG. 3B). It is getting bigger. The lateral displacement of the slide pin 9C refers to the distance from the center of the slide pin 9C to the imaginary line Lo.

  In other words, the lateral shift amount W1 when the center of the slide pin 9C is at a position lower than the swing center O1 of the stick arm 5 has the same height or swing as the center of the slide pin 9C with the swing center O1. It is larger than the lateral displacement amount W2 at a position higher than the movement center O1.

  The base portion 3 is provided with a first guide portion 3B for guiding the displacement of the rod material 9D. The first guide portion 3B has a through hole 3C through which the rod material 9D passes, as shown in FIG. 5 (b). Then, the rod material 9D is in sliding contact with the inner peripheral surface of the through hole 3C, whereby the displacement of the rod material 9D is guided.

  The first guide portion 3B is provided on one end side of the base portion 3 in the extending direction of the guide groove 3A. On the other end side of the base portion 3 in the extending direction of the guide groove 3A, a pair of support portions 3D for swingably supporting the stick arm 5 is provided. The base portion 3 is integrally molded of resin together with the first guide portion 3B and the like.

  As shown to Fig.3 (a), the 2nd guide member 15 which guides the displacement of rod material 9D is provided in the site | part shifted to the handle part 7 side from the 1st guide part 3B. As shown in FIG. 7A, the second guide member 15 has a through hole 15A penetrating in the displacement direction of the rod member 9D.

  The through hole 15A is a hole into which the shaft 7A (see FIG. 8A) of the handle 7 can be inserted. The shaft portion 7A is a substantially cylindrical portion to which the rod member 9D is inserted and fixed as shown in FIG. 8 (b). Then, the inner peripheral surface of the through hole 15A is in sliding contact with the outer peripheral surface of the shaft portion 7A, thereby indirectly guiding the displacement of the rod material 9D.

  At one end side of the handle portion 7 in the axial direction of the shaft portion 7A, a grip portion 7B extending in a direction substantially orthogonal to the axial direction is provided. The user can operate the handle 7 by gripping the grip 7B. The axial direction of the shaft portion 7A is a direction coincident with the longitudinal direction of the rod material 9D.

  The outer peripheral surface of the shaft portion 7A is provided with a projection 7C which protrudes in a direction orthogonal to the axial direction. The protrusion 7C according to the present embodiment is constituted by a ridge extending along the axial direction.

  As shown in FIG. 7B, the second guide member 15 is provided with a groove 15B in which the protrusion 7C is fitted so as to be displaceable. The groove 15B extends in a direction parallel to the axial direction of the shaft 7A, as shown in FIG. 7 (a).

The axial length of the protrusion 7C, the position of the protrusion 7C in the axial direction, and the axial length of the groove 15B are provided to satisfy at least the following two conditions.
The condition is that "the protrusion 7C is fitted into the groove 15B when the stick arm 5 is in the first position", and "the protrusion 7C is a groove when the stick arm 5 is in the second position. It is "having left 15B".

  When "the protrusion 7C is separated from the groove 15B", the handle 7 is in the fourth position. Therefore, when the handle 7 is at the fourth position, the user can rotate the handle 7 about the axis.

  Therefore, when the handle 7 rotates such that the protrusion 7C is displaced from the groove 15B when the handle 7 is in the fourth position, as shown in FIG. 7A, the protrusion 7C is a second guide member. It engages so that it may hook on end face 15C of the extension direction one end side of slot 15B among 15.

  Since the end surface 15C is the upper end surface of the second guide member 15, the handle portion 7 is held at the fourth position when the projection 7C is engaged with the end surface 15C. That is, the end surface 15C of the second guide member 15 functions as an engaged portion for holding the handle portion 7 at the fourth position, and the projection 7C is engaged with the end surface 15C that constitutes the engaged portion. Act as a department.

  The taper part 15D is provided in the site | part which follows the groove part 15B among the end surfaces 15C which are engaging parts. The tapered portion 15D is a surface inclined so as to be lower as it approaches the groove 15B. In addition, said "falling" means "falling down" in the up-down direction in the state in which the door stopper apparatus 1 was attached to the door.

  The other end in the extension direction of the protrusion 7C, that is, a portion 7D in contact with the end surface 15C when engaged with the end surface 15C is a tapered surface inclined along a curved surface or a tapered portion 15D as shown in FIG. Is configured.

  The base 3 and the second guiding member 15 are connected by a connecting member 17 made of a ferromagnetic metal material, as shown in FIG. The connecting member 17 has a band plate portion 17A extending from the base portion 3 toward the second guide member 15, and protruding portions 17B protruding from both ends in the width direction of the band plate portion 17A. It is formed in the shape of a letter.

  Permanent magnets 13A and 13B are fixed to both end sides in the longitudinal direction of the connecting member 17. The fixed portion of the permanent magnet 13A is a portion of the base portion 3 provided with the first guiding portion 3B. The part where the permanent magnet 13B is fixed is a connection part between the second guide member 15 and the connection member 17. Then, the guide base 11 is assembled at a position shifted from the permanent magnet 13A in the longitudinal direction of the connecting member 17.

  As shown in FIG. 1A, the side opposite to the surface on which the connecting member 17 and the guide base 11 are provided is covered by a bowl-shaped cover 19. Therefore, in the state where the door stopper device 1 is attached to the door, the transmission mechanism 9 such as the rod 9D and the operation frame 9A is covered by the cover 19.

3. How to use the door stopper device etc. 3.1 Attaching the door stopper device 1 to the door When the door stopper device 1 is used, the handle 7 is on the upper side of the stick arm 5 as shown in FIG. It is necessary to attach the door stopper device 1 to the door so as to be positioned.

  Specifically, when the door stopper device 1 is attached, the guide base 11 is positioned such that the handle portion 7 can be easily operated with the positioning end face 11A of the guide base 11 placed against the lower end face of the door. Select the mounting position of.

  Next, a screw (not shown) for fixing the guide base 11 to the base portion 3 is tightened to fix the guide base 11 to the base portion 3, and then a double-sided tape attached to the guide base 11 And the door stopper apparatus 1 is attached to a door by permanent magnet 13A, 13B.

3.2 Method of Use and Features of Door Stopper In the state where the projection 7C of the handle portion 7 is engaged with the end face 15C of the second guide member 15, as shown by the two-dot chain line in FIG. Since the handle portion 7 is held in the raised state (fourth position), the stick arm 5 is held in the state (second position) raised from the floor.

  Then, when the handle 7 rotates to a position where the protrusion 7C fits into the groove 15B, the handle 7 and the stick arm 5 etc. are moved by the gravity acting on the handle 7, rod 9D, actuation frame 9A and stick arm 5 It is displaced downward.

  As a result, the stick arm 5 is in the first position (in the lowered state) and the handle portion 7 is in the lowered state (the third position), and the tip of the stick arm 5 is in contact with the floor and the door is opened. It is held.

  When raising the stick arm 5 to the second position, the user pulls up the handle portion 7 to set the handle portion 7 to the fourth position, and then the protrusion 7C engages with the end face 15C of the second guide member 15. The handle portion 7 may be rotated to a matching position.

  As described above, in the door stopper device 1 according to the present embodiment, it is needless to say that there is no need to operate the stick arm 5 with a foot, and it is not necessary to bend the waist and operate the stick arm 5 by hand. Even the elderly with weakened legs can easily operate the door stopper device 1.

  The present embodiment is characterized in that the stick arm 5 is in the first position when the handle portion 7 is in the third position, and the stick arm 5 is in the second position when the handle portion 7 is in the fourth position.

  Thereby, in the present embodiment, the direction of the operation of the handle portion 7 and the direction of the operation of the stick arm 5 coincide with each other. Therefore, when the user operates the handle portion 7, it is possible to prevent in advance the erroneous operation.

  That is, in the present embodiment, the stick arm 5 is in the first position (in the lowered state) when the handle 7 is lowered (third position), and the stick is in the state where the handle 7 is raised (fourth position) The arm 5 is in the second position (in the raised state).

  On the other hand, if the direction of the operation of the handle portion 7 and the direction of the operation of the stick arm 5 are opposite, the stick arm 5 is in the second position (the third position) when the handle portion 7 is lowered. Because it is in the raised state, it is easy to induce an erroneous operation.

  In the transmission mechanism (reciprocating slider crank mechanism) 9 according to the present embodiment, the central position of the slide pin 9C is always shifted in the lateral direction with respect to the imaginary line Lo regardless of the position of the stick arm 5 It is characterized.

Thus, in the present embodiment, the parallel movement of the handle portion 7 can be reliably converted into the rocking movement of the stick arm 5.
That is, if the center position of the slide pin 9C is located on the imaginary line Lo, a moment for swinging the stick arm 5 is not generated, so the stick arm 5 can not be displaced smoothly.

  On the other hand, in the present embodiment, since the center position of the slide pin 9C is always shifted in the lateral direction with respect to the imaginary line Lo regardless of the position of the stick arm 5, the stick arm 5 is swung. The moment to make it always occurs. Therefore, the stick arm 5 can be displaced smoothly.

  The present embodiment is characterized in that the lateral shift amount W1 of the slide pin 9C at the first position is larger than the lateral shift amount W2 of the slide pin 9C at the second position.

  Thereby, in the present embodiment, since the moment generated when pulling up the handle portion 7 can be made larger than the moment generated when lowering the handle portion 7, the operability of the door stopper device 1 can be improved. it can.

  That is, since it is necessary for the user to act on the handle portion 7 against the gravity acting on the handle portion 7 and the stick arm 5 etc. in order to pull up the handle portion 7, when pulling up the handle portion 7, Compared to the case of lowering the handle portion 7, a large operating force is required.

  On the other hand, in the present embodiment, since the moment generated when pulling up the handle portion 7 can be increased, the operating force at the time of pulling up the handle portion 7 can be reduced, and the operability of the door stopper device 1 is improved. It can be done.

  In the present embodiment, a connecting member 17 made of a ferromagnetic metal material, which connects the base portion 3 and the second guide member 15, and permanent magnets 13A and 13B provided on both ends in the longitudinal direction of the connecting member 17 are provided. It is characterized by

  Thereby, in the present embodiment, while using the connecting member 17 as a frame of the door stopper device 1, it can also be used as an iron core for enhancing the magnetic force. Therefore, it is possible to obtain sufficient strength while reducing the number of parts as compared with the case where a frame is separately provided.

  As shown in FIG. 15A, the restricting portion 3E is configured by a slidable contact piece extending from between a pair of support portions 3D to the first guiding portion 3B (in the present embodiment, the upper side in the vertical direction). There is. That is, as shown in FIG. 15B, the restricting portion 3E is separated from the wall portion 3F of the base portion 3 via a predetermined gap, and the sliding contact portion 9J (provided in the operation frame 9A) It is a site | part which slidably contacts with FIG.16 (c)) so that contact is possible.

  In addition, at least one (both in the present embodiment) of the distal end side of the restricting portion 3E and the distal end side of the sliding contact portion 9J, a guide portion 3G which guides the sliding contact portion 9J to the gap between the restricting portion 3E and the wall portion 3F. , 9K are provided.

  As shown in FIG. 14B, the inner peripheral surface of the elongated hole 9B is provided with a recess 9L in which the slide pin 9C is fitted when the stick arm 5 is at the second position. The recess 9L is a recess having a circumferential inner circumferential surface as shown in FIGS. 16 (a) and 16 (b).

  As shown in FIG. 14 (a), an inclined surface 9M is provided on a portion of the inner peripheral surface of the long hole 9B which comes in contact with the slide pin 9C when the stick arm 5 is at the first position. It is done.

  The inclined surface 9M is a surface inclined with respect to the long diameter direction of the long hole 9B as shown in FIG. 16B, and is separated from the long diameter central axis L2 of the long hole 9B toward the one end side in the long diameter direction. It is inclined to

  The long diameter direction one end of the long hole 9B refers to the end in the displacement direction forward side when the stick arm 5 starts to be displaced from the first position toward the second position in the long diameter direction. Specifically, in FIG. 16B, the left end of the long hole 9B is referred to as one long diameter direction end of the long hole 9B.

<Features of this embodiment>
The present embodiment is characterized in that the restricting portion 3E is provided, so that the operating force at the time of displacing the stick arm 5 from the first position to the second position can be reduced.

  That is, the long diameter direction of the long hole 9B is orthogonal to the displacement direction of the handle portion 7. Then, the sliding pin 9C is slidingly displaced in the long hole 9B, whereby the vertical operation force (hereinafter referred to as the handle operation force) of the handle portion 7 is converted into a swing force that causes the stick arm 5 to swing. .

  Therefore, if the actuating frame 9A is displaced in the long diameter direction of the long hole 9B when the actuating frame 9A is displaced, the handle operation force can not be efficiently converted into the swinging force. For this reason, when the operation frame 9A is displaced in the long diameter direction of the long hole 9B, the user needs to exert a large handle operation force.

  On the other hand, in the present embodiment, since the restricting portion 3E is provided, it is possible to efficiently convert the handle operation force into the swing force. Therefore, the user can easily move the stick arm 5 up and down without exerting a large handle operation force.

  The present embodiment is characterized in that a recess 9L in which the slide pin 9C is fitted is provided on the inner peripheral surface of the long hole 9B when the stick arm 5 is at the second position. Thereby, the stick arm 5 at the second position can be held in a stable state.

  In this embodiment, in the inner peripheral surface of the long hole 9B, the inclined surface 9M is provided at a portion in contact with the slide pin 9C when the stick arm 5 is at the first position. It is characterized.

This makes it possible to further reduce the operating force when displacing the stick arm 5 from the first position to the second position.
That is, when the stick arm 5 is displaced from the first position to the second position, the stick arm 5 swings in the direction of the thick arrow D in FIG. When the stick arm 5 is displaced from the first position to the second position, the operation frame 9A is displaced in the direction of the thick arrow E, that is, in the direction orthogonal to the long diameter direction of the long hole 9B.

  The inclined surface 9M is inclined so as to be separated from the major axis L2 of the elongated hole 9B toward the one end in the major direction, so that the slide pin 9C moves toward the one end in the major direction by the displacement of the operation frame 9A. A force F having a component force of direction is generated.

  The force F does not include a component force in a direction that hinders the displacement of the stick arm 5. Therefore, it becomes possible to efficiently convert the handle operation force into the swing force. Therefore, it is possible to further reduce the handle operation force.
