Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a folding table with an improved storage section for a folding chair.

[Conventional technology]

As a conventional table of this kind, Utility Model Publication No. 52-2647
Publication No. (hereinafter referred to as Conventional Example 1) and Utility Model Application No. 1987-6
There is a technique described in Japanese Patent No. 4941 (hereinafter referred to as conventional example 2).

In Conventional Example t, a shelf is integrally provided on the lower surface of a table board which is pivotably mounted on the upper part of the legs via fasteners, and
A folding chair mounting frame is placed horizontally on the lower part of the legs, and when the table board is in the upright (folded) state, the folding chair is inserted between the table board and the shelf, and the chair is The lower end is supported on the mounting frame.

On the other hand, in Conventional Example 2, the bent pieces at both ends of the hanging rod for hanging the curtain board, which are bent in a U shape at the front upper part of the pillar having a top plate that can be folded and unfolded, are each horizontally pivoted. At the same time, a mounting frame for the folding chair is horizontally suspended at the lower part of the pillar, and the lower end of the folding chair inserted from above into the hanging rod is supported on the mounting frame. .

[Problem that the invention attempts to solve]

However, both of the above conventional examples 1 and 2 have the following problems.

In other words, in the case of Conventional Example 1, the distance between the veneer and the shelf must be set to a distance that allows the folding chair to be fully inserted in the folded state, which results in significant restrictions in table production. It has become.

Moreover, since the shelf usually has a plurality of shelf pipes arranged in parallel at regular intervals, when inserting a folding chair, the legs of the chair may get caught on the shelf pipes, making it difficult to insert the chair. , there is a risk that they may be damaged.

On the other hand, in the case of Conventional Example 2, the suspension rod into which the folding chair is inserted at the upper front surface of the pedestal is always exposed to the outside, so there is a drawback that the structure lacks simplicity.

In addition, especially when the table is used with the curtain plate attached, the hanging rods become a nuisance and pose a danger to inspection.

[Means for solving problems]

This invention was made to solve the above problems, and although it has a holding frame for storing folding chairs, the holding frame is not exposed to the outside when the top plate is in a horizontally unfolded position, and the top plate is not exposed to the outside. To provide a folding table having an ideal structure in which the holding frame can be expanded to the storage position only when storing the folding chair in a folded state.

In order to achieve the above-mentioned purpose, this invention includes a top support frame that is pivoted on the proximal side to the upper end of the pedestal, is expanded and held in a horizontal position, and can be folded to a hanging position along the pedestal, and a top support frame that is The base end is pivotally supported by the attached top plate and the pivot shaft of the top plate support frame, and is housed within the frame of the top plate support frame along the back surface of the top plate, and within the frame when the top plate is folded. A holding frame for storing a folding chair that is rotatably displaceable from a storage position to a horizontally deployed position; a stopper provided on the upper end side of the pillar for supporting the holding frame in a horizontal position; and a stopper for supporting the holding frame in the horizontal position. A folding chair mounting frame for supporting the lower end of a folding chair that is horizontally suspended between the pillars at the bottom and inserted between the top plate in the folded state and the holding frame in the horizontally unfolded position. It is characterized by a configuration including.

A preferred embodiment of this invention will be described below with reference to the drawings.

In the folding type one-sleeved table shown in FIG. 1, the upper end of the pedestal 1, which is planted toward the rear of the pair of left and right pedestals 2 having casters 3, is as shown in FIG. A bracket bearing 4 whose tip end side projects in front of these is integrally formed.

On the distal end side of the trunk bracket bearing 4, the proximal end side of a rectangular top plate support frame (hereinafter abbreviated as frame in the embodiment) 5 is pivoted so as to be vertically movable about a shaft P1.

Therefore, the frame 5 has a mounting configuration that allows it to be freely rotated between an unfolded position in which it is in a horizontal position at the upper end of the shelf column 1 and a folded position in which it is in a substantially vertical position along the front surface of the pedestal column 1. .

A top plate 6 is integrally attached to the floating frame 5 by screws or the like.

Further, at a lower and spaced apart position of the bracket bearing 4 on the shelf post 1, the base end of the shelf 7 is pivotally supported about a shaft P2 so as to be movable up and down.

The shelf 7 is always maintained parallel to the frame 5 by a link member 8 extending between its tip side and the foot 5 and pivotally supporting both ends. A locking pin /9 for locking the frame 5 in the horizontally deployed position is inserted between the shelf 7 and the base end pivot shaft P2.

As shown in more detail in FIGS. 4, 6, and 7, the lock pin 9 is formed as a tapered pin portion 9a that protrudes from the inner surface of the shelf post 1 and has a gradually smaller diameter on the tip side, and is supported by a spring in the direction of protrusion. 10 and is always energized.

On the other hand, lock receiving pieces 11 are integrally connected to both inner wall surfaces of the top support frame 5 and hang down along the inner surface of the pedestal 1 when the frame is in a horizontally deployed position.

The lock receiving piece 11 has a lock hole 12 into which the tapered pin portion 9a of the lock pin 9 is inserted when the frame 5 is in the horizontally deployed position.

The lock receiving piece 11 is bent so that the distal end 11a is gradually separated from the inner surface of the pillar 1 so as to push the lock pin 9 against the spring 10 when the frame 5 is expanded.

In this case, the distance l11 between the bent tip of the lock receiving piece 11 and the pillar 1 is the protrusion length 12 of the lock pin 9 from the pillar wall surface.
is set larger.

Therefore, when the distal end side 11a of the lock receiving piece 11 reaches the lock pin 9 when the frame 5 is expanded, the lock pin 9 is pushed as the distal end abuts against the curved surface of the distal end side 11a of the lock receiving piece 11. It moves backward against the spring 10.

Then, the lock hole 12 of the lock receiving piece 11 is connected to the lock pin 9.
When they match, the lock pin is advanced by the force of the spring 10 and fitted into the lock hole 12, whereby the frame 5, top plate 6, and shelf 7 are each held in a locked state in the horizontally deployed position.

When folding the table from such a state, it is necessary to release the above-mentioned lock.

For this purpose, lock release levers 13 are integrally connected to both ends of the base end pivot shaft P2 of the shelf 7.

The lever 13 extends toward the lock pin 9 along the inner surface of the footnote 1 on both sides, and the pivot shaft P is attached to the extending end side of the lever 13.
An arcuate hole 14 centered at 2 is formed.

A tapered pin portion 9a of the lock pin 9 passes through this arcuate hole 14.

In this state, the lock receiving piece 11 is attached to the taper pin portion 9a.
Unless they abut, the proximal step wall 9b of the taper pin portion 9a
are adapted to press into engagement.

Further, the lever 13 has a handle piece 15 integrally curved on the tip side.

The handle piece 15 extends in a direction to intervene between the frame 5 and the pillar 1 when the table is folded.

Therefore, when the table is folded, the lever 13 is rotated when the handle piece 15 is pushed toward the pillar 1 side by the frame 5.

In such a lever 13, the arcuate hole 14 is connected to the handle piece 1.
The side opposite to 5 is tapered so as to gradually approach the pedestal 1 side.

Therefore, when the front end hole on the side of the handle piece 15 that is farthest from the wall surface of the pedestal 1 is engaged with the lock pin 9, the arcuate hole 14 is formed so that the lock pin protrudes largely from the pedestal 1. When held in the locking position and the rear end hole closest to the pedestal 1 is engaged with the lock pin 9, the lock pin is held in the unlocked position where the lock pin is moved backward against the spring 10. I will do it.

That is, when the table is folded, the lever 13 is
Since the handle piece 15 is pressed, the lever 13 is displaced to a position where the front end hole of the arcuate hole 14 engages with the lock pin 9, and in this state, the lock pin protrudes to the locking position. .

Therefore, when the frame 5 is expanded from this state, the lock receiving piece 11 descends toward the lock pin 9, and the lock receiving piece 11 moves back against the spring 10 against the lock pin 9 on the way down. let

When the frame 5 is expanded to a horizontal position, the lock hole 12 of the lock receiving piece 11 matches the lock pin 9, so the pin 9 moves forward under the force of the spring 10 and fits into the lock hole 12. As a result, the frame 5 and the like are locked in the horizontally deployed position as described above.

From the locked state, when the handle piece 15 of the lever 13 is pulled away from the pillar 1, the engagement position of the lock pin 9 with respect to the arcuate hole 14 becomes closest to the pillar 1.
By changing to the rear end hole side, lever 1 at this time
3, the lock pin 9 is moved back against the spring 10.

As a result, the lock pin 9 is removed from the lock hole 12, so that the frame 5 is unlocked.

By releasing the lock, the frame 5, top plate 6 and shelf 7
etc. become a co-moving body and are folded into a hanging position along the pedestal 1 by their own weight.

In the above description, the levers 13 are respectively connected to both ends of the base end pivot shaft P2 of the shelf 7.
are integrally connected by the pivot shaft P2, so when folding the table as described above, only one of the levers 1
There is an advantage that by simply operating the lever 3, the other lever can be operated in the same manner to simultaneously release the locks on both sides of the frame 5 on both side pillars 1, 1.

Further, the folding table having the above structure has a holding frame 16 for storing a folding chair mounted on the frame 5.

As shown in FIGS. 4, 5, and 7, the retaining ring 16 has leg pieces 17 that are integrally connected to each other at both ends and extend in the same direction, and the tips of the leg pieces are attached to the retaining frame. It has a mounting structure in which the base end is rotatably supported on the pivot shaft P1 of the frame 5.

In this case, the holding frame 16 is attached within the frame 5.

Therefore, the holding frame 16 is rotatable between an unused position where it is stored within the frame of the frame 5 and a used position where it extends in a direction substantially perpendicular to the back surface of the top plate 6 when folded. There is.

On the other hand, the bracket bearings 4 at the upper ends of the pillars 1 on both sides are provided with stoppers 18 for holding the retaining ring 16 in the use position, that is, in the horizontal deployment position.

In addition, between the lower parts of the pillars 1 on both sides, there is a mounting frame 1 for a folding chair.
9 is integrally mounted horizontally.

The mounting frame 19 has the shape of a 1/2-inch groove, and is hung horizontally with its open end facing upward.

When the folding chair 20 is stored and held on the folded table, the holding ring 16 in the frame 5 is expanded horizontally and supported on the stopper 18.

In this state, the folded chair 20 is inserted from above between the back surface of the top plate 6 and the holding frame 16, and the lower end of the chair is held on the mounting frame 19.

As a result, the folding chair 20 and the folding table can be put away in a compact combined state when they are not in use.

In the above embodiment, the lock receiving piece 11 is integrally formed with a mounting piece 11b (see FIG. 5) at the base end, and the piece of this mounting piece is fastened to the frame 5 with a bolt 21. There is.

For this reason, a bolt hole 11c is formed in the mounting piece 11b, and the bolt hole is formed to have a suitably larger diameter than the shaft diameter of the bolt 21.

Therefore, the position at which the mounting piece 11b is fastened by the bolt 21 can be changed as appropriate, and thereby the levelness of the top plate 6 at the unfolded position can be easily adjusted.

Further, as shown in FIGS. 8 to 10, the lock release lever 13 is connected to the pivot shaft P2 of the shelf 7 at the outer surface of the pillar 1.
It may be connected to

In this case, the lever 13 has an arcuate hole 14 fitted into the lock pin 9 so as to be slidable between the head 9b of the lock pin and the pedestal 1.

A handle piece 15/ is provided in the center of the back surface of the lever 13, and a bent piece 13' is provided at the - side edge.
is integrally bent, and when the bent piece is pushed by the top support frame 5 during folding and the lever 13 is rotated, the lock pin 9 is projected in the locking direction by the force of the spring. It has become.

Therefore, the lever 13 in this case also provides the same effects as in the previous embodiment.

As described above, with this invention, when the top plate is folded, the holding frame for storing folding chairs is unfolded horizontally and the folding chair is inserted into the holding frame, and the chair and table can be stored when not in use. Can be combined and stored in a compact state.

In particular, since the base end of the above-mentioned holding frame is pivotally supported by the thinning of the top plate support frame, the holding frame is inevitably housed within the top plate support frame when the top plate is in the horizontally deployed position. In this state, the holding frame is never exposed to the outside.

Therefore, there is no fear that the holding frame will be a problem when the table is used, and the aesthetic appearance of the table is also improved, increasing its commercial value.
