Description

Description: [Industrial application] The present invention relates to a furniture with a ceiling plate in which a ceiling plate is supported by a wall body such as a low partition through a bracket.

[Prior Art] As a furniture with a ceiling plate of this kind, a wall body such as a low partition having a hook hole in a joint portion, a bracket in which a hook provided at a base end is hooked in the hook hole, and a bracket A top plate attached to the above has been developed.

[Problems to be Solved by the Invention] By the way, in the conventional one, a plurality of downward claws bent downward are provided at the base end of the bracket.
The downward claws are hooked on the hook holes.

However, with such a structure, if a temporary lifting force acts on the top plate due to some kind of momentum, the downward claws of the bracket will come off the hook holes, and the top plate and the bracket will fall downward. Will be done. In recent offices and the like, it is often the case that various devices such as printers and displays are placed on the top plate for use, and if the top plate falls, not only will serious damage be caused, but also office workers. May cause an accident or injury.

As a measure to deal with such a problem, for example, an upward claw that can be engaged with the hook hole by rotating the bracket downward is provided at the upper end of the base end of the bracket, and the upward claw is provided below the upward claw. It is conceivable that a downward claw that engages with another hook hole is provided by the pressing operation of the bracket after engaging with the hook hole. However,
Since the bracket supports the lower surface of the top plate, the upper edge of the neck portion of the upward claw, which serves as a rotation fulcrum when the upward claw is rotationally engaged with the hook hole, is the top plate of the top plate. It is usually located lower than the upper surface. Therefore, when the bracket is hooked on the hook hole and the top plate is mounted on the bracket, a required gap must be formed between the rear edge of the top plate and the surface of the wall body. Due to the interference between the top plate and the wall body, it becomes impossible to rotate the bracket upward and remove the upward claw from the hook hole.

Therefore, in such a thing, the top plate can be used in a state in which the top plate looks good and is brought into contact with or close to the wall body,
Moreover, it is not possible to meet the demand for easily changing the hooking position of the bracket without removing the top plate from the bracket.

The present invention was made in view of such circumstances,
It is an object of the present invention to provide a furniture with a ceiling plate that can effectively prevent a problem that the ceiling plate comes off during use due to an unexpected external force, and can also meet the above-mentioned demand.

[Means for Solving the Problems] The present invention takes the following means in order to achieve the above object.

That is, the furniture with a ceiling plate according to the present invention is a wall body having a hook hole in a joint portion, and a bracket provided with a horizontal plate portion on an upper edge of a vertical plate portion having a base end hooked in the hook hole. ,
A top plate attached to a horizontal plate portion of the bracket, the upward claw capable of engaging with a hook hole by rotating the bracket downward at an upper end of a base end of the bracket. And a downward claw that engages with another hook hole when the bracket is pushed down after the upward claw is engaged with the hook hole. The upper edge of the neck portion is set to be higher than the upper surface of the top plate attached to the horizontal plate portion.

[Operation] In this type of furniture, during use, the bracket is subjected to a moment to rotate in the direction in which the front end is lowered due to its own weight, the weight of the top plate, the weight of the placed object on the top plate, and the like. There is.

If the lifting force temporarily acts on the top plate or the bracket in this state, the downward claw may move up to a position where it can be disengaged from the hook hole, but the upward claw is deeply engaged with the upper edge of the hook hole. Will meet. Then, at the moment when the lifting force disappears, a force in the direction of pushing the downward claw into the hook hole is applied by the moment, and the original hooked state is restored. Therefore, it is impossible for the bracket to come off the wall body due to an unexpected external force.

On the other hand, if you want to change the height of the tabletop, remove the object placed on the tabletop, lift the tabletop and bracket upward, and then move the tabletop in the direction in which the top edge becomes higher. And rotate the bracket. In this case, since the upper edge of the neck of the upward claw, which is the pivot point of the invention, is located above the upper surface of the top plate, the top of the top plate is not rotated when the bracket is rotated upward. The entire plate will once move away from the wall. Therefore, even when the top plate is set to be in contact with or very close to the wall in the use state, the bracket can be attached to and detached from the hook hole while the top plate is attached to the bracket. .

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

As shown in FIGS. 1 and 2, the furniture with the top plate is
A top plate 3 is supported by a low partition 1 as a wall via a bracket 2.

As shown in FIGS. 2 and 3, the low partition 1 is formed by connecting adjacent panels 11 with each other through prismatic pipe-shaped columns 12. A plurality of hook holes 13 are formed vertically at a predetermined pitch in the front and rear central portions of the pillar 12, and these hook holes 13 face a joint portion 14 formed between adjacent panels 11. There is.

As shown in FIGS. 1 and 3, the bracket 2 is provided on the vertical plate portion 21 having an inverted L-shape in a side view, in which the vertical dimension of the base end side is set large, and on the upper edge of the vertical plate portion 21. It is provided with a horizontal plate portion 22 and is integrally formed by pressing a sheet metal material. An upward claw 23 is provided on the upper end of the base end of the vertical plate portion 21, and a plurality of downward claws 24, 25, 26 are provided below the upward claw 23. The upward claw 23 has the hook hole 13 with the upper edge 23a ₁ of the neck portion 23a as a fulcrum.
When a circular arc A having a radius corresponding to the vertical dimension of is drawn, the geometrical dimension is set so that the tip portion 23b fits within the circular arc A. Then, with the bracket 2 tilted upward, the upward claw 23 is inserted into the desired hook hole 13, and the upper edge 2 of the neck portion 23a of the upward claw 23 is inserted.
3a ₁ is brought into contact with the upper edge 13a of the hook hole 13 and the bracket 2 is rotated to a horizontal posture, whereby all the claws 23, 24, 25, 26 are inserted into the corresponding hook holes 13. I am trying to get it. After inserting the claws, the bracket 2 is pushed downward so that all of the downward claws 24, 25, 26 are hooked on the lower edge 13b of the corresponding hook hole 13. Even when the downward claws 24, 25, 26 are hooked in the hook hole 13, the tip portion 2 of the upward claw 23 is also held.
The upper edge 13b of the hook hole 13 to which the upper edge 23b _{1 of} 3b corresponds
It is set to be located above a.

The top plate 3 has a width dimension corresponding to the joint spacing of the low partition 1, and the lower surfaces 32 of both end portions 31 thereof are supported by the horizontal plate portion 22 of the bracket 2 attached to each joint portion 14. To fix the top plate 3, a bolt (not shown) inserted from below into the bolt insertion hole 22b of the horizontal plate portion 22 is screwed into an insert nut (not shown) embedded in the top plate 3. It is done by. Two symmetrical brackets 2 are hooked on each joint portion 14 of the low partition 1, and two end portions 31 of each top plate 3 are fixed to each bracket 2.

Then, this is the vertical plate portion 21 of the bracket 2.
By extending the base end upper edge portion 21a of the above, the upper edge 23a ₁ of the neck portion 23a of the upward claw 23 becomes higher than the upper surface 33 of the top plate 3 attached to the horizontal plate portion 22. Is set.

With such a structure, when the lifting force is temporarily applied to the top plate 3 and the bracket 2 in the use state as shown in FIGS. 1, 2, and 4, the downward claw 24 Two
Although the upward movement of the hooks 5 and 26 may rise to a position where they can be disengaged from the hook holes 13, the upward claws 23 serve as the upper edge 1 of the hook holes 13.
3a will be engaged more deeply. Then, at the moment when the lifting force disappears, a force in the direction of pushing the downward claw 24 into the hook hole 13 acts due to the moment caused by gravity or the like, and the original hooked state is restored. Therefore, the bracket 2
It is unlikely that the will fall off the pillar 12 of the low partition 1. That is, to remove the bracket 2,
Once the bracket 2 is lifted upward, its front end 2
Although it is necessary to pull out the upward claw 23 from the hook hole 13 while rotating in the direction in which the side a becomes higher, the possibility that such an operation is performed by an unexpected external force is extremely low. Even more, it is almost impossible to perform such an operation even if it is intentional in a state where various devices are placed on the top plate 3.

On the other hand, if you want to change the height position of the top plate 3,
After removing the upper placed object, the top plate 3 and the bracket 2 are lifted upward, and thereafter, the bracket 2 and the top plate 3 are rotated in a direction in which the front ends 2a, 3a become higher. At this time, this is the upward claw 2 that serves as the fulcrum of rotation.
Since the upper edge 23a ₁ of the neck portion 23a of 3 is positioned above the upper surface 33 of the top plate 3, when the bracket 2 is rotated upward, as shown by the solid line in FIG. The whole 3 will move away from the surface 11a of the panel 11 of the low partition 1. Then, as shown by an imaginary line in FIG. 5 from this state, the bracket 2 and the top plate 3 are further rotated by extracting the upward claw 23 from the hook hole 13 and further rotating the bracket 2 and the top plate 3. Can be released from the low partition 1. Then, by performing the above operation in reverse, the bracket 2 and the top plate 3 can be reattached at a desired height position.

If this is the case, the top plate 3 in use
Even when the rear end 3b is set to come into contact with or be in close proximity to the surface 11a of the panel 11, the top plate 3 is still attached to the bracket 2 and the bracket 2 is attached to the hook hole 13.
It is possible to attach and detach with respect to.

The shape of the upward claw is not limited to that of the above embodiment, and may be, for example, as shown in FIG. That is, the upward claw 123 shown in FIG. 6 has an auxiliary claw portion 123c that engages with the lower edge 13b of the hook hole 13 at the lower part thereof.

The shape and number of the downward claws are not limited to those in the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention.

Further, it goes without saying that the wall body is not limited to the low partition.

[Advantages of the Invention] Since the present invention has the above-described configuration, it is possible to reliably prevent the problem that the bracket comes off and the top plate falls due to an unexpected external force with a simple configuration. It is possible to ensure safety.

Moreover, even when the rear end of the top plate is in contact with or very close to the wall body, the bracket can be attached / detached to / from the hook hole while the top plate is attached by performing the required operation. Therefore, there is a desire to eliminate the gap between the top plate and the wall to improve the appearance, and the mounting position of the top plate can be set appropriately without the troublesome work of removing the top plate from the bracket. The excellent effect that the desire to be able to change can be satisfied together is obtained.
