Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an improvement of a folding table.

[Conventional technology and its issues]

When a large room space such as a hall is used as a conference room, a folding table is sometimes used as a conference table. There is a risk that it may not be suitable for use in a room space.

That is, in general, folding tables tend to be relatively compact so that they do not require a large operating force when setting and folding the table.

Therefore, when a conventional folding table is used to convert a large room space into a conference room, etc.
A very large number of folding tables must be prepared and aligned, and therefore many workers and many working hours are required to set up and clean up the tables, which is disadvantageous.

Therefore, if the conventional folding table is made larger, the number of tables to be prepared will be reduced.
This saves the number of workers and work time required for setting up and cleaning up.

However, if the folding table is large and the top plate forming the table surface is folded in half, each top plate member must be formed to have a relatively large weight. Therefore, during the folding operation, it is necessary to support each top plate member with a large force while performing the operation.

As a result, not only is there a disadvantage that work efficiency is reduced when cleaning up the table, but if the top plate is folded carelessly, a shock may be generated, resulting in noise or damage to the folding table itself. This may also lead to other inconveniences.

This device was devised in view of the above-mentioned circumstances, and its purpose is to be able to form what is called a large type, and not require a large amount of operating force when folding it. Our goal is to provide you with a folding table that allows you to do it safely.

[Means to solve the problem]

In order to achieve the above object, the configuration of the present invention includes a leg member installed on a floor surface, a top plate connected to the upper end of the leg member, and a space between the leg member and the top plate. The top plate is made up of two opposing top plate members, and each top plate member is connected to the upper end of the leg member via a bracket attached to the inner side of the lower surface of each top plate member. The lower end of the damper is fixed to the leg member, while the upper end of the damper is connected to each of the brackets, and the lower end of the damper is fixed to the lower end of the at least one top plate member. The device is characterized in that it is provided with a locking device that prevents or allows.

[Effect]

By lifting upward the lower edge of each top plate in the folded state, that is, in the tilted state, each top board becomes horizontal, and as a result, the top board becomes horizontal. A predetermined table surface is formed by the upper surface.

Once each top plate member is in a horizontal position, this is maintained by a locking device.

When the locking device is released, each top plate member is tilted by its weight, that is, the top plate is folded in half.

At this time, the tilting speed of each of the top plate members is appropriately controlled by the damping action of the damper, and rapid tilting of each of the top plate members is prevented.

[Example] Hereinafter, this invention will be explained in detail based on the illustrated example.

As shown in the drawings, the folding table according to the invention includes a leg member 1 installed on a floor surface F, a top plate 2 connected to the upper end of the leg member 1, and the leg member 1 and the top plate. 2, and the top plate 2 has two top plate members 2 facing each other.
0, 21, and each top plate member 20, 21 has a bracket 2 attached to the inner side of the bottom surface of each top plate member 20, 21.
2 and 23, the damper 3 has its lower end fixed to the leg member 1, while its upper end is connected to each of the brackets. A locking device 4 for preventing or allowing rotation of the bracket 23 is provided on the lower surface of the top plate member 21. This will be explained in more detail below.

The leg member 1 is installed on a floor surface F or the like and is formed to support each of the top plate members 20 and 21 constituting the top plate 2 from below.

That is, in the illustrated example, the leg member 1 includes a base plate 10 and a post 11 whose lower end is connected to the central upper surface of the base plate 10 and whose upper end is connected to the top plate 2. It will be done.

It goes without saying that the base plate 10 is designed so as to allow the posts 11 to be arranged in series and to support the top plate 2 on the upper ends of the posts 11, safely and reliably.

Therefore, the material forming the base plate 10, its form, and other conditions are arbitrary, and generally known materials and means are selected as appropriate.

The above-mentioned post 11 has a so-called bifurcated upper end branched, and each branched portion 12, 13
Each top plate member 20 whose upper end constitutes the above-mentioned top plate 2,
It is said that it will be connected to 21.

Therefore, rotating shafts 14 and 15 are disposed at the upper ends of each of the branch members 12 and 13, respectively, and the rotating shafts 14 and 15
0 and 21, respectively.

On the other hand, as described above, the top plate 2 is composed of the two top plate members 20 and 21, and is formed so that it can be folded in half from the center.

Then, on the lower surface of each of the top plate members 20, 21, as described above, there are brackets 22, 2.
3 is attached, and the bracket 2
1 and 23 are each branch portion 12 of the post 11,
The rotating shafts 14 and 15 are pivotally connected to the upper ends of the rotating shafts 13, respectively.

Therefore, with the above structure, the top plate 2 of this invention is foldable.

The damper 3 is disposed between the leg member 1 and the top plate 2, and its lower end is fixed to the post 11 constituting the leg member 1, while its upper end is fixed to the link member 30, It is connected to each of the brackets 22 and 23 via 31.

That is, the damper 3 has the lower ends of the link members 30, 31 pivotally attached to its upper end, and the upper ends of the link members 30, 31 are connected to the brackets 22, 23. .

The pivot positions of the link members 30 and 31 relative to the brackets 22 and 23 are as follows:
Compared to the pivoting positions of the upper ends of the branch portions 12, 13 of the post 11 to the brackets 22, 23, the pivoting positions of the link members 30, 31 to the brackets 22, 23 are lower. It is said to be the so-called inside.

Therefore, when each of the top plate members 20, 21 is rotated about the pivoted portion to each bracket 22, 23, the damper 3 is extended, and at the time of the extension operation, the damper 3 has a predetermined size. A damping force is generated to appropriately control the rotation, that is, the tilting speed, of each of the top plate members 20 and 21.

Therefore, if the damper 3 is formed so that its damping effect can be made variable, the rotation operation of each of the top plate members 20 and 21 about the rotating shafts 14 and 15, that is, the rotation of the top plate 2 It is also possible to preferentially make one of the setting and folding operations easier.

The lock device 4 includes an operating knob 40 disposed on the lower surface of one of the top plate members 21 and
Although not shown, a stopper activated by the operation of the operation knob 40 pivots the pivoting portion of each top plate member 20, 21 to each bracket 22, 23. It is formed to prevent rotation about the center.

Therefore, in the folding table according to this invention formed as described above, the top plate 2 is in the bifold state, that is, each top plate member 2 is in the tilted state.
By lifting the lower edge portions 0 and 21 upward, each top plate member 20 and 21 becomes horizontal, and as a result, a predetermined table surface is formed by the upper surface of the top plate 2.

After each of the top plate members 20 and 21 is placed in a horizontal state, that is, when the top surface of the top plate 2 is used as a table surface, this state is maintained by the locking device 4.

On the other hand, when the locking device 4 is deactivated, each of the top plate members 20 and 21 is tilted by its weight, that is, the top plate 2 is folded in half from its center.

At this time, the tilting speed of each of the top plate members 20 and 21 is appropriately controlled by the damping action of the damper 3, and a rapid tilting of each of the top plate members 20 and 21 is prevented.

Therefore, the tilting of each top plate member 20, 21 is carried out quietly, and inconveniences such as impacting people and causing noise or damage to the folding table itself are prevented. That will happen.

[Effect of idea]

According to the present invention, there are the following effects.

1. Since the bracket is attached to the inner side of the lower surface of the top plate member, and this bracket is rotatably pivoted to the upper end of the leg member, the top plate member will not move unless the rotation of the bracket is prevented by a locking device. The outer side of the bracket is heavier than the pivot point, and the bracket rotates and folds under its own weight, improving operability during storage.

2. Since a damper is installed between the leg members and the top plate, even if the top plate member rotates under its own weight, its speed is controlled by a damping effect, preventing sudden rotations, shocks, and impact noise. can be prevented from occurring.

3. Since a locking device is provided to prevent or allow rotation of the bracket, the top plate can be held horizontally or can be selectively retracted by operating this locking device.
