When the sliding plate 34 is in a fixed state, the connecting mechanism 40 restricts movement of the lock receiving member 32 in the front-to-rear direction. When the sliding plate 34 is in an unlocked state, the connecting mechanism 40 allows the sliding plate 34 to move vertically in conjunction with a movement of the lock receiving member 32 in the vertical direction, and the sliding plate 34 to move vertically relative to the lock receiving member 32 in conjunction with the movement of the lock receiving member 32 in the front-to-rear direction. As a result, the lock receiving member 32 can be held in place by returning the fixed member 30 and the sliding plate 34 to their fixed states after adjustment.SELECTED DRAWING: Figure 4

Description

[Technical Field]

[0001] The present invention relates to a strike for a sliding door. [Background technology]

[0002] In the sliding door striker described in Patent Document 1 below, when the adjustment screw is turned, the side bracket moves up and down. When the side bracket moves up and down, the cam engagement fitting (lock receiving member) moves back and forth in the sliding door opening and closing direction. This makes it possible to adjust the position of the cam engagement fitting in the sliding door opening and closing direction. [Prior art documents] [Patent documents]

[0009] The sliding door strike 10 according to this embodiment will be described below with reference to the drawings. Note that the arrows UP, FR, and RH shown as appropriate in the drawings indicate the upper side, front side, and right side of the sliding door strike 10. In the following description, when the up / down, front / rear, and left / right directions are used, they refer to the up / down, front / rear, and left / right directions of the sliding door strike 10 unless otherwise specified.

[0010] As shown in FIG. 1 , the sliding door strike 10 is provided in a door frame 50 of a building. The door frame 50 has a pair of front and rear vertical frames 50A extending in the up-down direction, and the sliding door strike 10 is provided in one of the vertical frames 50A. A sliding door 52 is provided within the door frame 50 so as to be movable in the front-to-back direction (opening and closing direction). The sliding door 52 is formed in the shape of a substantially rectangular plate with its thickness direction in the left-to-right direction and its length direction in the up-to-down direction. When the door frame 50 is closed by the sliding door 52, the sliding door 52 is positioned in front of the sliding door strike 10 of the vertical frames 50A, and the sliding door 52 and the sliding door strike 10 are positioned opposite each other in the front-to-back direction.

[0011] As shown in Figures 2 to 4, the sliding door striker 10 is configured to include a locking mechanism 20, a fixing member 30, a lock receiving member 32, slide plates 34 as a pair of left and right inner members, and a connecting mechanism 40. The sliding door striker 10 is configured so that the lock receiving member 32 can be moved up and down and back and forth from an initial position (the position shown in Figure 4) to adjust the up and down and front and back positions of the lock receiving member 32. Each component of the sliding door striker 10 will be described below.

[0012] (About Toroyoke 20) The troyoke 20 forms the outer shell of the sliding door strike 10. The troyoke 20 is formed as a hollow, approximately rectangular box extending in the vertical direction as a whole. The troyoke 20 is built into the vertical frame 50A. The troyoke 20 is composed of a troyoke main body 22 that forms the front part of the troyoke 20, and a back panel 24 that forms the rear part of the troyoke 20.

[0013] The troyoke body 22 is made of a metal plate. The troyoke body 22 extends in the vertical direction and is bent in a generally U-shape that opens to the rear in a plan view from above. Specifically, the troyoke body 22 is composed of a front wall 22A whose thickness direction is the front-to-rear direction, and a pair of left and right side walls 22B that extend rearward from both left and right ends of the front wall 22A. Both up-to-down ends of the front wall 22A serve as mounting portions 22C, which are located outward in the vertical direction from the side walls 22B. Mounting holes 22D are formed through the mounting portion 22C in the front-to-rear direction.

[0014] An opening 22E is formed through the front wall 22A in the vertical middle portion thereof, and is formed in a generally rectangular shape with the vertical direction as its longitudinal direction. The opening 22E is a hole portion that allows the locking piece 52A (see FIG. 4) of the sliding door 52 to enter the troyoke 20. Specifically, with the sliding door 52 in the closed state, operating the locking device of the sliding door 52 causes the locking piece 52A to enter the troyoke 20 through the opening 22E. Furthermore, a screw insertion hole 22F is formed through the front wall 22A above the opening 22E. The screw insertion hole 22F is formed in the shape of an elongated hole with the vertical direction as its longitudinal direction. A set screw 26 is inserted into the screw insertion hole 22F from the front side.

[0015] The back plate 24 is made of a metal plate and is formed as a substantially elongated plate with the front-to-rear direction as the plate thickness direction and the up-to-down direction as the longitudinal direction. Both vertical ends of the back plate 24 are bent in a crank shape toward the front and outward in the vertical direction, and are positioned adjacent to the rear of the mounting portion 22C of the troyoke body 22. Mounting holes 24A are formed through both vertical ends of the back plate 24 at positions corresponding to the mounting holes 22D. The mounting portion 22C of the troyoke body 22 and both vertical ends of the back plate 24 are fastened and fixed to the front surface of the vertical frame 50A with screws (not shown). This secures the troyoke 20 to the door frame 50.

[0016] Furthermore, a pair of upper and lower guide holes 22G are formed in each side wall 22B of the troyoke body 22. The guide holes 22G are formed in a concave shape that extends in the vertical direction and is open to the rear, and the openings of the guide holes 22G are blocked from the rear by the back plate 24.

[0017] A decorative panel 28 is provided on the front side of the troyoke 20, covering the troyoke 20 from the front. The decorative panel 28 is formed as a substantially elongated plate with its thickness extending in the front-to-rear direction and its length extending in the up-down direction. Both vertical ends of the decorative panel 28, together with the troyoke 20, are fastened to the door frame 50. A communication hole 28A is formed in the vertical middle of the decorative panel 28 at a position corresponding to the opening 22E of the troyoke 20. The communication hole 28A is formed in a substantially rectangular shape with its length extending in the up-down direction. When the locking piece 52A of the sliding door 52 enters the troyoke 20, the locking piece 52A passes through the communication hole 28A. An exposure hole 28B is formed through the decorative panel 28 at a position corresponding to the screw insertion hole 22F of the troyoke 20. The exposure hole 28B is formed in a substantially elongated shape with its length extending in the up-down direction. The head of the set screw 26 is disposed within the exposure hole 28B.

[0018] (Regarding the fixing member 30) The fixing member 30 is formed in a generally rectangular box shape that is open to the rear and is disposed within the troyoke 20. A threaded portion 30A is formed in the bottom wall (front wall) of the fixing member 30. The threaded portion 30A is generally cylindrical and protrudes rearward from the bottom wall of the fixing member 30. A female thread is formed on the inner periphery of the threaded portion 30A, and the set screw 26 described above is threadedly engaged with the threaded portion 30A. Furthermore, the rotation of the fixing member 30 around the threaded portion 30A is limited by a lock receiving member 32 described below. As a result, by rotating the set screw 26 in the tightening direction (clockwise as viewed from the front), the fixing member 30 tightens a slide plate 34 described below to the front wall 22A of the troyoke main body 22, and the fixing member 30 is fixed to the troyoke 20 together with the slide plate 34. A connecting groove 30B for connecting a lock receiving member 32 (described later) is formed through the left and right side walls of the fixed member 30, and the connecting groove 30B extends in the front-to-rear direction and is open on the front side.

[0019] (Regarding the lock receiving member 32) The lock receiver member 32 is formed in a generally elongated shape extending in the vertical direction. The lock receiver member 32 has a pair of left and right side plate portions 32A, each of which is formed in a generally elongated plate shape with its thickness in the horizontal direction and its length in the vertical direction. The lock receiver member 32 has a lock receiver portion 32B. The lock receiver portion 32B is formed in a plate shape with its thickness in the front-to-rear direction, and both left and right ends of the lock receiver portion 32B are connected to the front ends of the side plate portions 32A. This connects the middle portions of the side plate portions 32A in the vertical direction via the lock receiver portion 32B. When the sliding door 52 is locked, the locking piece 52A engages with the lock receiver portion 32B in the vertical direction, and when the sliding door 52 is unlocked, the engagement between the locking piece 52A and the lock receiver portion 32B is released.

[0020] The lock receiving member 32 is housed inside the troyoke 20, and the fixing member 30 is disposed between the upper ends of a pair of side plate portions 32A. When the lock receiving member 32 is housed, the lock receiving portion 32B is disposed in a position that is visible to the front from the opening 22E of the troyoke 20 and the communication hole 28A of the decorative panel 28. Specifically, in the initial position of the lock receiving member 32, the lock receiving portion 32B is disposed within the opening 22E. Furthermore, the lock receiving member 32 is housed within the troyoke 20 so that it can move relative to the troyoke 20 in the front-to-back and up-and-down directions.

[0021] A connecting protrusion 32C is provided on the upper end portion of the side plate portion 32A. When viewed from the left and right, the connecting protrusion 32C is formed in a generally rectangular shape and protrudes inward in the left and right direction from the side plate portion 32A. The connecting protrusion 32C is inserted into the connecting groove 30B of the fixed member 30 so as to be movable in the front-rear direction but immovable in the up-down direction. This connects the lock-receiving member 32 to the fixed member 30 so as to be movable relative to the fixed member 30 in the front-rear direction but immovable relative to the fixed member 30 in the up-down direction.

[0022] The side plate portion 32A is provided with three connecting shafts 42 that constitute a connecting mechanism 40 (described later). Each connecting shaft 42 is formed in a generally cylindrical shape with its axial direction extending in the left-right direction, and protrudes outward in the left-right direction from the side plate portion 32A. The connecting shafts 42 are provided at both ends of the side plate portion 32A in the up-down direction and at a middle portion of the side plate portion 32A in the up-down direction.

[0023] (Regarding slide plate 34) The slide plate 34 is formed as a generally elongated plate with its thickness in the left-right direction and its length in the up-down direction. The slide plate 34 is housed within the troyoke 20 and is positioned adjacent to the left-right outer sides of the side plate portion 32A of the lock receiver member 32. Specifically, the slide plate 34 is positioned between the side plate portion 32A and the side wall 22B of the troyoke body 22, and the left-right movement of the slide plate 34 is restricted by the lock receiver member 32 and the troyoke body 22. A pair of upper and lower guide protrusions 34A are formed at the rear end of the slide plate 34. When viewed from the front-rear direction, the guide protrusions 34A are bent into a generally U-shape that opens inward in the left-right direction and protrude outward from the slide plate 34 in the left-right direction. The guide protrusions 34A are inserted into the guide hole 22G of the troyoke 20 so as to be movable in the up-down direction but immovable in the front-rear direction. This connects the slide plate 34 to the troyoke 20 so as to be movable relative to the troyoke 20 in the up-down direction but immovable relative to the troyoke 20 in the front-rear direction.

[0024] Three connecting holes 44 that constitute the connecting mechanism 40 are formed through the slide plate 34. Each connecting hole 44 is formed in an elongated hole shape, and the longitudinal direction of the connecting hole 44 is inclined relative to the up-down direction. Specifically, when viewed from the front-to-rear direction, the connecting hole 44 extends in a direction that inclines rearward as it extends upward. The diameter of the connecting shaft 42 described above is set slightly smaller than the width dimension of the connecting hole 44. The connecting shaft 42 is inserted into the longitudinal middle portion of the connecting hole 44.

[0025] A fixing piece 34B is provided at the upper end of the front end of the slide plate 34, and the fixing piece 34B extends inward in the left-right direction from the slide plate 34. The fixing piece 34B is arranged between the front wall 22A of the troyoke body 22 and the fixing member 30. In addition, the threaded portion of the set screw 26 is arranged between the pair of left and right fixing pieces 34B. As a result, by rotating the set screw 26 in the tightening direction, the pair of left and right fixing pieces 34B are fixed to the troyoke 20 together with the fixing member 30.

[0026] (Regarding the connecting mechanism 40) The connecting mechanism 40 is a mechanism that connects the lock receiving member 32 and the slide plate 34, and is composed of the connecting shaft 42 of the lock receiving member 32 and the connecting hole 44 of the slide plate 34. When the slide plate 34 and the fixed member 30 are fixed to the troyoke 20, the connecting shaft 42 engages with the inner periphery of the connecting hole 44 in the up-down and front-back directions, so that movement of the lock receiving member 32 in the up-down and front-back directions is restricted.

[0027] Furthermore, as will be described in detail later, when the slide plate 34 and the fixing member 30 are released from the locking mechanism 20, the slide plate 34 moves up and down in conjunction with the up and down movement of the lock receiving member 32 by the connecting mechanism 40. In this state, the slide plate 34 moves up and down relative to the lock receiving member 32 in conjunction with the front-to-rear movement of the lock receiving member 32 by the connecting mechanism 40.

[0028] (Action and effect) Next, the operation and effect of this embodiment will be described, along with a description of how to adjust the position of the lock-receiving member 32 in the vertical and front-rear directions.

[0029] In the sliding door strike device 10 configured as described above, for example, when the lock receiver member 32 is in its initial position, by rotating the set screw 26 in the tightening direction, a tightening force is generated from the fixed member 30 to the fixed piece 34B of the slide plate 34 toward the front. This fixes the fixed member 30 and the slide plate 34 to the locking mechanism 20. The lock receiver member 32 is connected to the fixed member 30 so as to be immovable relative to it in the vertical direction but movable relative to it in the front-to-rear direction. Furthermore, when the slide plate 34 is in its fixed state, the connecting shaft 42 engages with the inner periphery of the connecting hole 44 in the vertical and front-to-rear directions, restricting the movement of the lock receiver member 32 in the vertical and front-to-rear directions. Therefore, the movement of the lock receiver member 32 relative to the fixed member 30 in the front-to-rear direction is restricted. As a result, the lock receiver member 32 is held in its initial position. In addition, when the slide plate 34 is in a fixed state, the connecting protrusion 32C may engage with the inner part of the connecting groove 30B before the connecting shaft 42 and the connecting hole 44 engage in the vertical direction, thereby restricting the vertical movement of the lock receiving member 32.

[0030] To adjust the vertical position of the lock receiver member 32, the set screw 26 is rotated in the release direction (counterclockwise when viewed from the front) to release the clamping force of the fixed member 30 on the slide plate 34, thereby releasing the fixed state of the fixed member 30 and slide plate 34 to the troyoke 20. The lock receiver portion 32B of the lock receiver member 32 is then manually moved vertically to adjust the vertical position of the lock receiver member 32. Because the lock receiver member 32 is connected to the fixed member 30 so as not to be able to move relative to it in the vertical direction, when the lock receiver member 32 moves vertically, the fixed member 30 also moves vertically (see Figures 5 and 6). Furthermore, when the lock receiver member 32 moves vertically, the connecting shaft 42 of the lock receiver member 32 presses the inner periphery of the connecting hole 44 of the slide plate 34 upward or downward.

[0031] Here, the connecting hole 44 is inclined rearward as it extends upward when viewed from the left-right direction. The slide plate 34 is connected to the troyoke 20 so as to be movable vertically relative to the troyoke 20 but not movable forward or backward relative to the troyoke 20. Therefore, when the connecting shaft 42 presses the inner periphery of the connecting hole 44 upward or downward, the connecting shaft 42 engages with the connecting hole 44 vertically. As a result, the connecting shaft 42 and the connecting hole 44 move vertically together (see Figures 5 and 6). That is, the connecting mechanism 40 allows the slide plate 34 to move vertically in conjunction with the vertical movement of the lock receiver member 32. After adjusting the vertical position of the lock receiver member 32, the fixed member 30 and the slide plate 34 are fixed to the troyoke 20 with the set screw 26, thereby maintaining the lock receiver member 32 in the adjusted position.

[0032] When adjusting the front-rear position of the lock receiver member 32, the fixed state of the fixed member 30 and the slide plate 34 by the set screw 26 is released, as described above. Then, the lock receiver member 32 is manually moved in the front-rear direction to adjust the front-rear position of the lock receiver member 32. The lock receiver member 32 is connected to the fixed member 30 so as to be movable relative to it in the front-rear direction. Therefore, when the lock receiver member 32 moves in the front-rear direction, the front-rear position of the fixed member 30 does not change, but the lock receiver member 32 moves relative to the fixed member 30 in the front-rear direction (see Figures 7 and 8). Furthermore, when the lock receiver member 32 moves in the front-rear direction, the connecting shaft 42 of the lock receiver member 32 presses the inner periphery of the connecting hole 44 of the slide plate 34 forward or backward.

[0033] Here, the connecting hole 44 is inclined rearward as it extends upward when viewed from the left-right direction. The slide plate 34 is connected to the troyoke 20 so as to be movable up and down relative to the lock receiver 32 but not to be movable forward or backward relative to the lock receiver 32. Therefore, when the connecting shaft 42 presses the inner periphery of the connecting hole 44 forward or backward, the slide plate 34 is prevented from moving forward or backward, and the slide plate 34 moves upward or downward relative to the lock receiver 32 (see FIGS. 7 and 8). Specifically, the connecting hole 44 slides on the outer periphery of the connecting shaft 42, and the connecting shaft 42 moves relative to the connecting hole 44 in the longitudinal direction of the connecting hole 44. In other words, the connecting mechanism 40 allows the pair of slide plates 34 to move up and down relative to the lock receiver 32 in conjunction with the forward and backward movement of the lock receiver 32. After adjusting the front-to-rear position of the lock receiving member 32, the fixing member 30 and the slide plate 34 are fixed to the troyoke 20 with the set screw 26, thereby holding the lock receiving member 32 in the adjusted position.

[0034] As explained above, in the sliding door strike 10, the lock receiving member 32 is connected to the fixed member 30 so as to be immovable relative to the fixed member 30 in the vertical direction but movable relative to the fixed member 30 in the front-rear direction. The sliding plate 34 is fixed to the troyoke 20 together with the fixed member 30 by the set screw 26. The lock receiving member 32 and the sliding plate 34 are further connected by the connecting mechanism 40.

[0035] When the slide plate 34 is in the fixed state, the movement of the lock receiver member 32 in the front-to-rear direction is restricted by the connecting mechanism 40. This allows the lock receiver member 32 to be held by the fixed member 30 and slide plate 34 in the fixed state.

[0036] Furthermore, when the sliding plate 34 is in the unlocked state, the connecting mechanism 40 causes the sliding plate 34 to move up and down in conjunction with the up and down movement of the lock receiver member 32. As a result, when adjusting the up and down position of the lock receiver member 32, the fixed member 30 and the sliding plate 34 are moved up and down together with the lock receiver member 32, and after the adjustment, the fixed member 30 and the sliding plate 34 are returned to the locked state, thereby holding the lock receiver member 32. In other words, when adjusting the up and down position of the lock receiver member 32, the lock receiver member 32, fixed member 30, and sliding plate 34 move up and down together.

[0037] Furthermore, when the sliding plate 34 is in the unlocked state, the connecting mechanism 40 causes the sliding plate 34 to move vertically relative to the lock receiving member 32 in conjunction with the forward / backward movement of the lock receiving member 32. As a result, when adjusting the forward / backward position of the lock receiving member 32, the lock receiving member 32 is moved relative to the fixed member 30 and the sliding plate 34, and after the adjustment, the fixed member 30 and the sliding plate 34 are returned to the locked state, thereby holding the lock receiving member 32. In other words, when adjusting the forward / backward position of the lock receiving member 32, the position of the fixed member 30 does not change, and the sliding plate 34 moves vertically relative to the lock receiving member 32 while maintaining its forward / backward position.

[0038] As described above, according to the striker for sliding door 10 of this embodiment, the position of the lock-receiving member 32 can be adjusted in the up-down direction and the front-rear direction. Therefore, the convenience of the striker for sliding door 10 can be improved.

[0039] The slide plate 34 is connected to the locking mechanism 20 so as to be movable relative to the lock receiver 32 in the vertical direction but not in the front-to-rear direction. The connecting mechanism 40 includes a connecting shaft 42 provided in the lock receiver member 32 and a long connecting hole 44 formed in the slide plate 34. The connecting hole 44 is inclined rearward as it extends upward when viewed from the left and right, and the connecting shaft 42 is movably inserted into the connecting hole 44. This allows the slide plate 34 to move vertically together with the lock receiver member 32 when adjusting the vertical position of the lock receiver member 32, as described above. Furthermore, the slide plate 34 can move vertically relative to the lock receiver member 32 when adjusting the front-to-rear position of the lock receiver member 32. Furthermore, when the slide plate 34 is fixed, the movement of the lock receiver member 32 in the vertical and front-to-rear directions can be restricted by the connecting hole 44 and the connecting shaft 42. Furthermore, as described above, the front-to-rear positions of the fixing member 30 and the sliding plate 34 are maintained when adjusting the vertical position or the front-to-rear position of the lock receiving member 32. This makes it possible to adjust the vertical position and the front-to-rear position of the lock receiving member 32 while preventing the sliding door strike 10 from becoming larger in size in the front-to-rear direction.

[0040] In addition, a pair of slide plates 34 are provided on both the left and right sides of the lock receiver member 32. This allows the lock receiver member 32 to be supported from both the left and right sides by the fixed slide plates 34. This makes it possible to maintain a good holding state of the lock receiver member 32.

[0041] In this embodiment, the connecting shaft 42 is provided on the lock-receiving member 32 and the connecting hole 44 is formed in the slide plate 34, but the connecting shaft 42 may also be provided on the slide plate 34 and the connecting hole 44 may be formed in the lock-receiving member 32.

[0042] Furthermore, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
