Description

The present invention relates to a slide latch for locking a hinged door of a storage such as a trunk room, a hinged door device, and a trunk room using them.

In recent years, with the diversification of lifestyles, there is an increasing need for trunk rooms (also called rental spaces, rental boxes, etc.) that rent storage spaces for storing user's luggage and clothes. This trunk room rents out storage space to users according to the contract period, and rents out to other users once the contract is completed, and it is characteristic that users change in a relatively short period of time.

The hinged door that opens and closes the entrance to this trunk room needs to be locked to prevent theft. For this locking, a locking device used for a general home entrance door can be used, but it is expensive. In particular, it is very costly to exchange a new key every time the user changes. Therefore, for example, as disclosed in Patent Document 1, it is common to lock the hinged door by sliding the latch body (also referred to as a bar) and lock the latch body with a padlock. By doing so, the key can be exchanged easily and at low cost.

The base plate 30 is formed in a size that covers the square hole 4 of the hinged door 3 from the outside, and four insertion square holes 31 are formed at positions corresponding to the fixing holes 6. The base plate 30 is inserted by inserting the fixing screw 20 from the outside of the insertion angle hole 31 and penetrating the fixing hole 6 of the hinged door 3 and the insertion angle hole 31 of the inner base plate 30, and then screwing the nut 21 from the inside. It can be attached by doing.

As shown in FIG. 6, the fixing screw 20 is provided with a rectangular portion 24 between the screw portion 22 and the head portion 23. The rectangular portion 24 is formed to be substantially equal in size to the square shape of the insertion square hole 31, and the rectangular portion 24 is fitted into the insertion square hole 31 so that the fixing screw 20 rotates when the nut 21 is attached or detached. It is designed not to be done.

Further, as shown in FIGS. 3 to 5, the head 23 of the fixing screw 20 is not provided with a cross groove or a hexagonal hole into which a tool such as a screwdriver or a hexagon wrench is inserted, unlike a general screw. Therefore, the fixing screw 20 cannot be removed from the outside, and cannot be removed unless the nut 21 is turned from the inside.

Further, as shown in FIGS. 3 and 4, the base plate 30 is formed with a slide insertion hole 35 extending in the left-right direction. A slide handle 40, which will be described in detail later, is inserted into the slide insertion hole 35, and functions to guide the slide handle 40 to move in the left-right direction.

Further, the base plate 30 is provided with an L-shaped plate 32 as shown in FIGS. 3 to 5 and 7. The L-shaped plate 32 is composed of a horizontal plane portion 32a having a horizontal plane and a mounting surface portion 32b extending substantially vertically downward from the horizontal plane portion 32a. The mounting surface portion 32b is addressed to the inside of the base plate 30 (the hinged door 3 side) and is fixed by the knock pin 36. The horizontal surface portion 32a projects outward through the slide insertion hole 35, and as shown in FIG. 4, two locking holes 33 penetrating in the vertical direction are provided.

As shown in FIGS. 3 to 5, the slide handle 40a includes a locking plate portion 41a and a grip portion 41b located on the outside of the base plate 30, a mounting surface portion 41c located on the inside of the base plate 30, and a latch body mounting portion 41d. It is composed of.

The locking plate portion 41a is placed on the upper side of the horizontal surface portion 32a of the L-shaped plate 32 and is attached so as to be movable in the left-right direction. Further, the locking plate portion 41a is provided with two locking holes 42 penetrating in the vertical direction. The locking hole 42 coincides with the locking hole 33 of the horizontal surface portion 32a in the vertical direction in the state after the locking operation of the slide latch 10 (the state shown in FIG. , 42 can be passed to lock.

The grip portion 41b is formed by bending the right end portion of the locking plate portion 41a upward.
The user can move the slide handle 40a in the left-right direction by using the grip portion 41b.

As shown in FIGS. 5, 7, and 8, the mounting surface portion 41c is formed so that the inner end portion of the locking plate portion 41a is bent upward. As shown in FIGS. 3 and 4, the mounting surface portion 41c is arranged inside through the slide insertion hole 35 of the base plate 30.

Further, a slide elongated hole 43 extending in the left-right direction is formed in the mounting surface portion 41c1, and a slide shaft 34 provided on the base plate 30 is inserted into the slide elongated hole 43. The mounting surface portion 41c1 is guided by the slide shaft 34 so that it can freely move in the left-right direction.

The latch body mounting portion 41d1 is formed by bending the upper end portion of the mounting surface portion 41c1 inward. Further, the latch body mounting portion 41d1 is formed with two engaging claws 45 having an inner end portion further extended inward.

On the other hand, unlike the outer slide handle 40a, the inner slide handle 40b is formed so that the height dimension of the mounting surface portion 41c2 in the vertical direction is shorter. Further, the engaging claw 46 having the inner end portion of the latch body mounting portion 41d2 extended is also long on the left and right, and is composed of one.

As shown in FIGS. 5, 7, and 8, the latch body 50 is configured separately from the slide handle 40. The latch body 50 is formed in a plate shape that is long in the left-right direction, and is arranged so that the plate-shaped plane faces the outside and the inside. As shown in FIG. 5, the latch body 50 is formed with one inner handle mounting hole 51 on the lower side in the vertical direction and two outer handle mounting holes 52 on the upper side penetrating in the plate thickness direction. The above-mentioned engaging claw 46 is inserted into the inner handle mounting hole 51 in the plate thickness direction of the hinged door 3, and two engaging claws 45 are inserted into the two outer handle mounting holes 52 in the plate thickness direction.

The height dimension of the inner handle mounting hole 51 and the outer handle mounting hole 52 is equal to the height difference between the mounting surface portions 41c1 and 41c2 described above. That is, with the engaging claws 45 and 46 inserted into the latch body 50, the height positions of the locking plate portions 41a of the slide handles 40a and 40b are set to be the same.

Further, the outer handle mounting hole 52 and the engaging claw 45 are inserted (play-fitted) with a certain amount of play (play) with a gap in the left-right direction and the up-down direction. Similarly, play is provided in the inner handle mounting hole 51 and the engaging claw 46. That is, the latch body 50 is adapted to move freely outward and inward within a range that does not disengage from the engaging claws 45 and 46.

As shown in FIGS. 3 and 7, the length of the latch body 50 in the left-right direction does not protrude to the left of the door tip 3a of the hinged door 3 in the state before the lock operation of the slide latch 10, and is in the state after the operation. Therefore, as shown in FIGS. 4 and 8, the door tip 3a is projected from the door end 3a.

As shown in FIGS. 3, 4 and 9, the door tip side plate 60 is fitted into the recess 7 of the door tip 3a and attached so as to be substantially flush with the door tip 3a. A protruding square hole 61 is formed in the door end side plate 60 at a position corresponding to the protruding hole 5, and the latch body 50 projects from the protruding square hole 61. Further, the door end side plate 60 is formed with two mounting holes 62 at the top and bottom, and a screw 63 is inserted into the mounting holes 62 to be fixed to the hinged door 3.

In this way, the latch body 50 is arranged inside the width of the plate thickness of the hinged door 2, and the latch body 50 is slid toward the door tip 3a to protrude inside the width of the plate thickness, so that the hinged door is projected. It is not necessary to provide a space for arranging and sliding the latch body 50 on the outside or the inside of the 3. As a result, only the slide handles 40a and 40b need to be provided on the outside and the inside of the hinged door 3, and the slide latch is compared with the case where the latch body is arranged on the outside of the hinged door as in the conventional patent document 1. The appearance of 10 is simple and neat.

Further, as shown in FIG. 9, the runout suppressing member 64 is fitted inside the protruding hole 5 of the hinged door 3. The runout suppressing member 64 is made of an elastic material such as stainless steel, and when the latch body 50 protrudes, it enters the inside of the U-shape in a plan view, the opening portion on the left side is expanded, and the latch body 50 is elastic. Is sandwiched between them to suppress rattling in the front-rear direction (the thickness direction of the hinged door 3).

Next, the slide latch, the hinged door device, and the operation / operation of the trunk room using them according to the embodiment of the present invention will be described with reference to FIGS. 3, 4, 7, and 8.
When the user on the outside operates the slide latch 10 from the pre-operation state (pre-locking state; see FIGS. 3 and 7) to the post-operation state (post-locking state; see FIGS. 4 and 8). The user grabs the grip portion 41b and moves the slide handle 40a to the left side (in the direction of arrow B in FIG. 3).

In this case, the slide handle 40a moves to the left along the slide insertion hole 35. Further, the slide handle 40a is guided by the slide slot 43 into which the slide shaft 34 is inserted, and is linearly moved to the left.

Then, the latch body 50 loosely fitted with the slide handle 40a is also pushed out to the left side, and the latch body 50 protrudes from the protruding square hole 61. The building frame 2 is formed with a recess that is not shown at a position corresponding to the latch body 50, and the protruding latch body 50 enters the recess and is locked (latched). At this time, since the latch body 50 has play in the plate thickness direction (front-rear direction) of the hinged door 3, even if there is a mounting adjustment error of the hinged door 3, it surely enters the recess.

Further, by performing these reverse operations, the user on the outside can operate from the state after the operation to the state before the operation.

On the other hand, the user inside also moves the slide handle 40b on the inside to move the slide handle 40b on the inside from the state before the operation to the state after the operation, or from the state after the operation to the state before the operation, as in the case of moving the slide handle 40b on the outside. Can be operated up to. That is, since the latch body 50 is assembled to both the slide handles 40a and 40b, the latch body 50 can be slid in conjunction with the operation of either the outer or inner slide handles 40a or 40b. Therefore, even if the user is locked from the outside while inside the trunk room, the lock can be released from the inside, so that the user is not trapped inside.

Further, in the state after the operation, as shown in FIGS. 4 and 8, the locking hole 33 of the L-shaped plate 32 and the locking hole 42 of the slide plate 40a (40b) coincide with each other in the vertical direction, and are viewed in the drawing. It can be locked with a padlock. Two pairs of locking holes 33, 42 are provided in the left-right direction, one for the user (borrowing side of the trunk room) to lock, and the other for the administrator (the manager (rental side of the trunk room)). This is because the lender) locks it as needed.

In addition, even if the user is locked and trapped from the outside while inside the storage space of the trunk room, he / she can go out by the following procedure.

The user on the inside turns and removes the four nuts 21 from the inside. At this time, since the rectangular portions 24 of the four fixing screws 20 are fitted in the insertion angle holes 31 of the outer base plate 30, the fixing screws 20 can be easily removed without rotating even if the nut 21 is turned. Can be done.

Then, the inner base plate 30 is pulled inward to remove it. At this time, since the latch body 50 is only loosely fitted in the plate thickness direction by the engaging claws 36, the slide handle 40b can be removed together with the base plate 30. Then, the outer base plate 30 is similarly pushed outward to remove the engaging claw 45, and the latch body 50 is pulled out from the square hole 4, so that the hinged door 3 can be opened from the outside while being locked with the padlock. it can.

Further, even if the fixing screw 20 is to be removed from the outside, it cannot be removed because the head of the fixing screw 20 does not have a hexagonal hole for inserting a tool. That is, a third party cannot disassemble the slide latch 10 for the purpose of theft.

According to the slide latch, the hinged door device, and the trunk room using them according to the embodiment of the present invention, the slide handles 40a and 40b operably provided on the outer and inner sides of the hinged door 3 and the outer and inner slide handles 40a and 40b, respectively. Since it is equipped with a latch body 50 that is assembled to both the slide handles 40a and 40b and slides in conjunction with the operation of either of the slide handles 40a and 40b, the slide latch is provided from either the inside or the outside of the hinged door 3. 10 can be operated. Therefore, even if the user is locked from the outside while inside the hinged door 3, the lock can be released from the inside, so that the user is not trapped inside.

Further, the slide handles 40a and 40b are symmetrically configured with the hinged door on the outside and inside of the hinged door 3, and the latch body 50 is arranged inside the width of the plate thickness of the hinged door 3, and the door tip 3a is inside this width. Since it is slid to the side, the latch body 50 can be configured without being arranged outside the hinged door 3. Therefore, it is only necessary to provide the slide handles 40a and 40b outside the hinged door 3, and the appearance of the slide latch 10 can be made simple and neat.

Further, base plates 30 for attaching the slide handles 40a and 40b are provided on the outer and inner sides of the hinged door 3, and the outer and inner base plates 30 are integrally fixed by fixing screws 20 penetrating in the plate thickness direction of the hinged door 3. Since the fixing screw 20 is configured to be removable only from either the inside or the outside of the hinged door 3, for example, the fixing screw 20 is locked and confined in the storage space of the trunk room inside the hinged door 3. Even if this is the case, the fixing screw 20 can be removed from the inside. Therefore, the hinged door 3 can be opened by disassembling the slide latch 10 while being locked from the inside. On the other hand, since the fixing screw 20 cannot be attached or detached from the outside, the risk of being stolen by removing the slide latch 10 can be eliminated.

Further, since the latch body 50 is formed separately from the outer and inner slide handles 40a and 40b, the latch body 50 can be easily attached and detached.

Since the latch body 50 is loosely fitted and assembled to the outer and inner slide handles 40a and 40b in the plate thickness direction, the hinged door 3 is displaced in the plate thickness direction due to an error in the mounting dimensions of the hinged door 3. Even so, since the latch body 50 can move by the amount of the loose fitting gap in the plate thickness direction, the latch body 50 can be more reliably latched with the building frame 2 side.

The slide latch, the hinged door device, and the trunk room using the slide latch and the hinged door device according to the embodiment of the present invention have been described above, but the present invention is not limited to the above-described embodiment and is based on the technical idea of the present invention. Various modifications and changes are possible.

For example, in the present embodiment, the left side portion of the hinged door 3 opens and closes (opens to the left), but there is also a hinged door device in which a hinge is provided on the left side portion and the right side portion opens and closes (opens to the right). Even in such a case, by exchanging the fixing screw 20 and the nut 21 of the present embodiment and attaching them with the outside and the inside reversed, it is possible to assemble the hinged door that opens to the right. As a result, even if there are a plurality of hinged door devices in the trunk room and the right-opening or left-opening hinged doors are arranged next to each other, the slide latch 10 is formed symmetrically in the front-rear direction, so that the height of the slide handle 40 is high. It can be installed with the same height. Therefore, the appearance of the entire trunk room can be improved.

Further, the slide latch 10 of the present embodiment can be used in addition to the hinged door 3 of the trunk room. For example, it can be attached to a hinged door type storage or a closet, which is installed in a general household, and the same effect as that of the present embodiment can be obtained. ]

Further, in the present embodiment, the nut 21 is attached to the inside of the hinged door 3 so that the nut 21 faces, so that the slide latch 10 can be disassembled from the inside. However, by exchanging the directions of the fixing screw 20 and the nut 21, the outside It can also be made so that it can only be disassembled from. The orientations of the fixing screw 20 and the nut 21 can be freely changed depending on the usage pattern and usage of the storage.
