Description

[Detailed Description of the Invention] The present invention has a handle for opening/closing the door, which is attached to the door so that it can be freely moved in and out of an operating position that projects toward the front of the door and a storage position that is retracted toward the inside of the door. A door fixing locking member that locks the stationary side locked member when the door is closed is linked to the handle so that the locking member acts only when the handle is in the retracted position; The present invention relates to a door closing/fixing device that is provided to be switched as the handle moves in and out.

This device for closing and fixing a door makes effective use of a handle that can be moved in and out in order to create a beautiful appearance in the closed state, and supports the handle by switching the locking member to open the door. When performing opening/closing operations, the locking member can be reliably switched to the unlocked state. However, some users open and close the door by directly supporting the door itself, and therefore operate the door to close without realizing that the locking member is in the locking state. This may cause the locking member and the locked member to collide with each other, leading to problems such as deformation and damage to the locking member and the linking mechanism between the locking member and the handle.

Incidentally, the above-mentioned trouble becomes more noticeable when the door is heavy, such as a sliding door that opens and closes the entrance to a storage room.

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to suppress deformation and damage to the locking member and the linking mechanism between the locking member and the handle through simple modification.

The characteristic configuration of the door closing/fixing device according to the present invention is as follows:
The engaged member is elastically supported so as to be freely retractable so that it can be pressed and displaced by the locking member in the locking state when the door is closed.

Next, the effects of the feature configuration of the present invention will be described.

In other words, even if the locking member is in the locking state during the door closing operation, the locking member is pressed and displaced backward by the locking member, thereby preventing the locking member and the linking mechanism between it and the handle. This prevents excessive load from being applied to the

Therefore, even if the door is closed with the locking member in the locking state, deformation and damage to the locking member and the linking mechanism between the locking member and the handle can be reliably suppressed. For example, the above-mentioned advantage is obtained by elastically supporting the locked member so that it can freely move backward. If the above advantages are obtained by modifying the locking member side, such as by providing an elastic flexible part in the linkage mechanism, the structure of the linkage mechanism will become complicated, making it difficult to manufacture and assemble. However, in this proposal, the desired objective can be achieved with an advantageous configuration in both the manufacturing and assembly aspects, in which the locked member, which is conventionally fixedly supported, is supported so as to be able to move backward freely. As a result, we have achieved a door closing and fixing device that has an advantageous configuration in terms of implementation, suppresses deformation and damage to the locking member and linkage mechanism, and can be used satisfactorily over a long period of time.

Next, embodiments of the present invention will be described based on the drawings.

Next, a device for closing and fixing the sliding door 1B will be described.

The sliding door 1B has a vertically long square shaft-like handle 37 for opening and closing the sliding door 1B, and a swinging type that locks a locked member 38 attached to the vertical frame 4 to fix the sliding door 1B in the fully closed position. A locking member 39 is attached to the handle 37 and the locking member 39, and the mounting structure of the handle 37 and the locking member 39 will be described below based on FIGS. 7 to 10.

Support case 40 for handle 37 and locking member 39
Mounting washer 41 that is fixed to the back of the sliding door 1B with a pin.
The support shaft 37A of the handle 37, and
Support shaft 42 for push operation member 42 for handle operation
Each of A is fitted and supported by guide members 43 and 44 so as to be slidable in a direction perpendicular to the door surface, and
Helical springs 45 and 46 are provided to urge the support shafts 37A and 42A to project toward the front side of the sliding door, respectively. A swinging arm 47 is locked by a spring 48, and is provided with a small protrusion 47A that locks the tips of the pins 37a and 42a attached to the support shafts 37A and 42A, respectively, so as to restrict the range of movement toward the front of the sliding door. A contact piece 47B is provided so as to be biased back to the operating side and is used to press and swing the swinging arm 47 toward the unlocking side by the pin 42a on the pushing operation member side.
The handle 37 is integrally formed with the swing arm 47 so that the handle 37 can be locked and held in a storage position where the entire handle is retracted to the inside of the sliding door, and
The swing arm 47 is activated by pushing the push operation member 42.
When the handle 37 is switched to the unlocked state, the handle 37 can be switched to an operating position in which the handle 37 protrudes toward the front side of the sliding door.

More specifically, the handle 37 is moved to the retracted position by pushing the handle 37 toward the sliding door and switching it to the operating position by pushing the push-operation member 42 in a small range. It is possible to move in and out of and to the operation position. however,
The handle side pin 37 constitutes the small protrusion 47A.
The amount of protrusion of the locking action portion _S1 of a is made smaller than the amount of protrusion of the locking action member _S2 of the push operation member side pin 42a, so that the handle side pin 37a can be smoothly engaged and disengaged. It is designed to reliably prevent the push operation member side pin 42a from coming off unexpectedly.

Further, in order to prevent the handle 37 from falling, a cylindrical guide member 49 that receives the side surface of the handle is fitted and attached to the sliding door 1A, so that even if a large force is applied to the handle 37 during opening and closing operations of the sliding door, the handle 37 The structure is such that the posture of the sliding door 1A relative to the sliding door 1A can be reliably maintained at a predetermined posture.

The locking member 39 is integrally provided with a forked portion 39A that engages with the handle side pin 37a.
The locking member 39 is configured to be switched into a locking state when the handle 37 is in the retracted position, and into a unlocked state when the handle 37 is in the operating position, as the handle 37 moves in and out. It has been done.

In short, the locking member 39 prevents the sliding door 1A from moving in a direction perpendicular to the door surface, so that the sliding door 1A can be reliably fixed in the fully closed position. No special operation is required for 39.

When the sliding door 1B is open, there is a risk that the support case 40 will collide with the left sliding door 1A, but the stopper 35 prevents the opening of the sliding door 1B from occurring. The range of movement to the side will be restricted.

Next, the locked member 38 will be explained with reference to FIGS. 7 and 11.

That is, a support plate piece 51 made of synthetic resin for the locked member 38 includes a first protrusion 51a that engages with the vertical frame 4 so as not to be able to move back and forth, a second protrusion 51b for guiding the locked member, and a flexible hole 53 which is provided with spring receiving portions 51c, and which engages the locking member 38 with the locking/disengaging hole 52 of the locking member 39 and the second protrusion 51b so as to be movable back and forth; A synthetic resin presser frame 55 having a U-shape in front and rear view, which is provided with spring insertion notches 54 and which presses the locked member 38 to prevent it from separating from the plate piece 51, is First and second protrusions 5
1a and 51b and screwed into the vertical frame 4, and the locked member 38
A pressing spring 57 is provided with one end received in the spring receiving portion 51c and inserted into the notch 54, which urges the member to return to the position where the member is to be locked. 38, sliding door 1
It is elastically supported so that it can be freely moved backward so that it can be pressed and displaced by a locking member 39 that is in a locking state during the closing operation of B.

In short, when the sliding door 1B is closed, even if the locking member 39 is in the locking state, the forked portion 39A of the locking member 39 is deformed and damaged due to the backward displacement of the locked member 38. I made sure there was nothing to do.

However, 58 in the figure indicates the first and second protrusions 51a,
51b, and whose tip is in contact with the vertical frame 4. It is an adjustment screw that is screwed into the vertical frame 4 and rotates the plate-like piece 51 away from the vertical frame 4 as it is rotated toward the vertical frame 4. By displacing the locked member 38 to the locking member 39
It is designed so that it can be moved to the side. That is, during assembly, etc., the position of the locked member 38 relative to the vertical frame 4 can be changed and adjusted so that the amount of protrusion of the locking member 39 into the locked member 38 is set to an appropriate amount.

In addition to the sliding door 1B that opens and closes the entrance to a storage room, the present invention can be applied to sliding doors and swinging doors that are used to open and close building entrances and furniture entrances. Suitable for doors that are flush with the wall.

Furthermore, in carrying out the present invention, in addition to allowing the handle 37 to be operated in and out using the push operation member 42,
For example, the specific configuration in which the handle 37 is provided so that it can be freely moved in and out can be modified in various ways, such as by releasing the lock as the handle 37 is pushed in a small range from the storage position and switching to the operating position.

Further, the locking member 39 can be provided in various ways depending on the structure of the door, such as being provided in a form that prevents the sliding door from moving in the direction along the door surface. The specific shape of the locked member 38 can be changed in various ways depending on the configuration of the locking member 39, and further,
The structure that supports the locking member 39 so as to be able to move backward is also
Various configuration changes can be made, such as elastic support using leaf springs.
