DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to storage furniture suitably used for display cases, display stands and the like.

[0002]

2. Description of the Related Art As furniture used for such a display case or the like, there is known a furniture having an opening for taking in and out an article such as an exhibit and an openable / closable cover body for closing the opening. Have been. However, if such a cover body is simply supported by the display case body with a hinge or the like and opened and closed, the hinge must be provided on the outer edge of the cover body due to its structure, and the hinge can be seen from the outside and the appearance can be seen. It may be damaged. The appearance of such display cases and the like is particularly important for the purpose, and thus such a configuration must be avoided as much as possible.

In view of the above, there has been proposed a configuration in which a cover body is slidably supported between a draw-out position and a storage position on a display case body so that the cover body can be opened and closed. With such a configuration, the cover body can be opened and closed at the pulled-out position where the cover body is slid out, so that a hinge or the like can be attached inward of the outer edge of the cover body, and in the closed state, the hinge or the like can be mounted. Can be arranged in a part that cannot be seen at all.

[0004]

However, with such a configuration, the cover body is slidable back and forth, so that it is difficult to bring the cover body into close contact with the opening edge.
There may be cases where a gap is formed between them and the appearance is impaired, or the sealing property cannot be ensured. In addition, a method of tightening the cover body with a screw, a snatch lock mechanism, and the like have been considered, but they have problems that it takes time to open and close, that there is vibration at the time of opening and closing, and that it is not possible to ensure airtightness. .

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention relates to a storage furniture designed to ensure the appearance, sealing, and simplicity of opening and closing operations. In addition to the basic structure in which the cover body is attached to the support body which can be moved forward and backward between the support body and the cover body so that the cover body can be opened and closed, a toggle action such that the force acting on this support body is switched at an intermediate portion of the advance / retreat area. It is provided with a biasing mechanism that operates.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A storage furniture according to the present invention has a furniture main body having an opening, a support supported by the furniture main body so as to be able to advance and retreat between a drawn-out position and a storage position, and this support. A cover body supported so as to be able to open and close between a closed posture and an open posture, and in a state where the support body is in the storage position and the cover body is in the closed posture, the cover body closes the opening. It is configured so that
When the support is closer to the extraction position than the intermediate position set between the extraction position and the storage position, the support is urged toward the extraction position, and the support is closer to the storage position than the intermediate position. Sometimes, a biasing mechanism for biasing the support in the direction of the storage position is provided.

In this case, as in the conventional case, the cover has a basic structure in which the cover body is openably and closably mounted on a support which is supported on the furniture main body so as to be able to move back and forth between a draw-out position and a storage position. Therefore, when the opening is closed by the cover body, it is possible to obtain a basic effect that it is possible to dispose a hinge or the like at a position that is not visible at all from the outside. As a result, no gap is formed between the opening edge and the cover body, and the appearance and the tightness of the storage space can be improved. On the other hand, since the direction of the biasing force of the biasing mechanism is reversed at the intermediate position, for example, if the cover body is moved from the retracted position to the intermediate position in order to pull out the cover body, the cover body can be moved without applying any operating force thereafter. It is automatically biased to the withdrawn position and held at that withdrawn position. As described above, the operation for opening and closing the cover body is extremely simple.

In order to realize such an urging mechanism with a simple mechanical structure, the urging mechanism moves in conjunction with a first fulcrum set on the furniture main body and a support, and moves at the intermediate position to the first fulcrum. It is preferable to exert an urging force in a direction to increase the separation distance from the second fulcrum set to be closest to the one fulcrum. As a specific embodiment in which the degree of freedom in setting the position of the urging mechanism, the magnitude of the urging force, and the like is large, and which can be easily realized with a simple configuration, the urging mechanism is provided in the third furniture set on the furniture body. An elastic restoring force acts in the extension direction between the rotating arm that can rotate forward and backward around the fulcrum following forward and backward movements of the support member and a second fulcrum set at the end of the first fulcrum and the end of the rotating arm. An elastic body, wherein the second fulcrum is located on an imaginary straight line connecting the first fulcrum and the third fulcrum at an intermediate position.

In order to move the cover body back and forth without impact,
It is desirable that the elastic body has a damper function such as a gas spring. As a specific mode in which the cover is supported by the support, the cover may be supported by the support so as to be horizontally rotatable or slidable between the closed position and the open position.

In an embodiment in which the effects of the present invention are remarkably exhibited, a furniture main body is provided on a base portion provided on a floor surface, and an article or the like can be accommodated inside the base portion provided on the base portion. And a transparent part, in which a support is supported by a base.

Is provided. Then, a portion of the inner surface of the waist panel portion 32 which is located inward from the one side edge 3a by a predetermined distance and the slide bodies 22 (b) and 22 (c) located on one side are connected by a hinge TB. The cover 3 is configured to rotate horizontally with respect to the support 2 to open and close between a closed posture S, which is parallel to the opening 11, and an open posture T, which is substantially orthogonal to the support 11. In addition, a portion of the inner surface of the waist panel portion 32 located inward from the other side edge 3b by a predetermined distance and the upright portion 211 located on the other side of the frame 21 are engaged with each other to close the posture. Lock means RC for holding S is provided. A handle, not shown, is provided on the outer surface of the waist panel 32 to release the locked state by the locking means RC.

In this embodiment, as shown in FIGS. 1 to 5, when the support 2 is located closer to the pull-out position P than the intermediate position R set between the pull-out position P and the storage position Q, this support An urging mechanism 4 urges the body 2 in the projecting direction and urges the support 2 in the immersion direction when the body 2 is closer to the storage position Q than the intermediate position R. The urging mechanism 4 includes a rotating arm 41 that can rotate around a third fulcrum X3 set on the display case main body 1, and a second fulcrum X2 and the third fulcrum X3 set at an end of the rotating arm 41. A coil spring 42 serving as an elastic body, each end of which is rotatably supported by a different portion and a first fulcrum X1 set on the display case main body 1.
In this embodiment, the urging mechanism 4 is provided.
A pair of slide bodies 22 (a), 22
(B) It is provided for each.

Each part of the biasing mechanism 4 will be described in detail. Specifically, as shown in FIG. 5, the rotary arm 41 has a long plate shape, and an intermediate portion thereof is connected to the bottom plate 121 of the base 12.
Is supported so as to be horizontally rotatable around a third fulcrum X3 set in the above. Then, one end of the rotating arm 41 is engaged with the lower support 22 (a) (or 22 (b)) via the engaging portion 43, and the rotating arm 41 follows the sliding movement of the support 2. Are configured to rotate forward and backward around the third fulcrum X3. This engaging portion 43 is rotated and slid into a long hole 43b provided, for example, by penetrating a pin 43a protruding downward from the bottom surface of the support 2 at one end thereof so as to extend along the longitudinal direction of the rotating arm 41. It is inserted as much as possible.

The coil spring 42 can be extended and contracted only in its longitudinal direction, and one end thereof is connected to a second fulcrum X2 set at the other end of the rotary arm 41 so as to be horizontally rotatable, and the other end is a base. First fulcrum X set on bottom plate 121 of section 12
It is supported so that it can rotate horizontally around one. In the present embodiment, the elastic return force of the coil spring 42 always acts in the direction in which the coil spring 42 extends, that is, the coil spring 42 acts as a pressing spring.

The positions of the fulcrums X1 to X3 are set such that the second fulcrum X2 is located on an imaginary straight line M connecting the first fulcrum X1 and the third fulcrum X3 at the intermediate position R. I have. In the present embodiment, the rotating arm 4
The third fulcrum X3 supports a portion deviated toward the support 2 side from the center position of 1, and an urging force greater than the elastic return force of the coil spring 42 is applied to the support 2 using the leverage principle. It is configured to work. The urging force is set to such a magnitude that a person can move the support 2 back and forth with normal force against the urging force. Needless to say, other changes such as setting the third fulcrum X3 closer to the second fulcrum X2 are possible in order to lengthen the slide stroke of the support 2.

According to the urging mechanism 4 configured as described above,
When the support 2 and the cover 3 are located at the intermediate position R, the first fulcrum X1, the second fulcrum X2, and the third fulcrum X3 are aligned on the virtual straight line M, so that the coil spring 42 acting on the second fulcrum X2 No component force for rotating the rotary arm 41 is generated in the extension force. When the support 2 and the cover 3 are moved from the intermediate position R to the pull-out position P, the rotary arm 41 rotates to move the second fulcrum X2 toward the storage position Q from the virtual straight line M. I do. As a result, a component force for further moving the second fulcrum X2 toward the storage position Q is generated by the extension force of the coil spring 42, and this component force rotates the rotary arm 41 to automatically move the support 2 to the extraction position P. It is elastically biased.

On the other hand, when the support 2 and the cover 3 are moved to the storage position Q side from the intermediate position R, the rotary arm 41 rotates, and the second fulcrum X2 is moved to the position P at the pull-out position P from the virtual straight line M. Move to the side. As a result, the coil spring 42
Due to the stretching force, a component force is generated to move the second fulcrum X2 toward the pull-out position P, and this component force rotates the rotary arm 41 to automatically elastically bias the support 2 to the storage position Q. .

Therefore, according to the present embodiment, when the cover 3 is pushed in the closed position S in order to close the opening 11 with the cover 3, the cover 3 is moved to the storage position Q side beyond the intermediate position R. From the point in time, the cover body 3 is automatically elastically urged to the storage position Q by the urging mechanism 4, and comes into close contact with the opening edge 11c at this storage position Q. On the other hand, when the cover body 3 is slid in the pull-out position P to open the opening 11 from this state,
The cover 3 is automatically moved by the urging mechanism 4 from the pull-out position P when the cover body 3 is moved to the pull-out position P beyond the intermediate position R.
To be elastically biased.

That is, the urging mechanism 4 ensures that the cover body 3 is in close contact with the opening edge 11c, and no gap is formed between them. Therefore, it is possible to maintain a good appearance and to secure the airtightness in the display case. Can be. Moreover, the cover body 3 is automatically urged in the desired direction by the urging mechanism 4 by sliding the cover body 3 from the pulled-out position P or the storage position Q to at least the intermediate position R.
Since the cover body 3 is held at the pull-out position P or the storage position Q, the opening / closing operation becomes extremely simple.

The present invention is not limited to the above embodiment. For example, by using a gas spring or the like having both an elastic deformation function and a damper function instead of the coil spring, the cover body can be brought into close contact with the opening edge gently without vibration. Further, the biasing mechanism may not be provided on the bottom plate as in the above embodiment, but may be provided on the side plate (waist panel) or the lower surface of the pedestal plate, or may be variously deformed such as by bending the shape of the rotating arm depending on the mounting position or torque. It is possible to do. FIG. 6 shows an example. In this modified example, the shape of the rotary arm 41 is formed in a V shape that is bent in the middle. As a result, it is possible to set the mounting position of the coil spring 42 to a different part from the above embodiment. In FIG. 6, parts corresponding to the above-described embodiment are denoted by the same reference numerals.

More specifically, each end of the elastic body is connected to a first fulcrum provided on the display case main body without using a rotating arm,
It may be directly rotatably connected to the second fulcrum set on the support. In this case, at the intermediate position, the first
The virtual straight line connecting the fulcrum and the second fulcrum may be set so as to be perpendicular to the direction in which the support moves forward and backward so that the elastic return force of the elastic body does not include the component in the direction of movement of the support.

In addition, the present invention is not limited to the display case, but can be applied to a storage furniture having an opening that can be opened and closed by a cover, and has the same effect. Others
It goes without saying that various modifications other than the illustrated examples are possible in other members and configurations such as the support body without departing from the spirit of the present invention.

[0026]

According to the present invention described in detail above, similarly to the prior art, the cover body is attached to the furniture body so as to be capable of opening and closing between the drawer position and the storage position so as to be able to open and close. With this basic configuration, it is possible to obtain a basic effect that it is possible to arrange a hinge or the like at a position that is not visible from the outside when the opening is closed by the cover body. In addition, since the urging mechanism urges the cover body to be in close contact with the opening edge, there is no gap between the opening edge and the cover body, and the appearance and the tightness of the storage space are improved. Can be obtained, which is not achieved by the conventional basic configuration. Further, the biasing mechanism performs a toggle action in which the biasing force reverses its direction at the intermediate position.For example, if the biasing mechanism is moved from the retracted position to the intermediate position in order to pull out the cover body, no operating force is applied thereafter. Even without this, the cover body is automatically biased to the pulled-out position and is held at the drawn-out position. As described above, the operation for opening and closing the cover body is extremely simple.

This urging mechanism is a separation distance between a first fulcrum set on the furniture main body and a second fulcrum set to move closest to the first fulcrum at an intermediate position by interlocking with the support. The urging mechanism can be realized with a simple configuration as long as the urging force is exerted in the direction in which is expanded. As a specific mode of such an urging mechanism, a rotating arm capable of rotating forward and backward following a reciprocating movement of a support around a third fulcrum set on the furniture body, and an end of the rotating arm are provided. An elastic body interposed between the second fulcrum and the first fulcrum and acting on an elastic return force in an extension direction, wherein the second fulcrum is located on an imaginary straight line connecting the first fulcrum and the third fulcrum at an intermediate position. And those configured to be located. In such a case, by changing the shape of the rotating arm and the connecting portion with the elastic body in various ways, the structure is simple, and the position of the urging mechanism, the magnitude of the urging force, etc. Can be set more freely.

If the elastic body has a damper function such as a gas spring, the cover body can be moved forward and backward without impact at the time of opening and closing. As a specific mode in which the cover is supported by the support, the cover may be supported by the support so as to be horizontally rotatable or slidable between the closed position and the open position.

A base part on which the furniture body is placed on the floor;
The effect of the present invention is particularly remarkable as long as it is provided with a transparent portion provided on the base portion and capable of accommodating an exhibit or the like therein, and the support is supported by the base. Will be played.
