Description

[Detailed description of the invention] [Industrial field of application] The present invention securely locks an auxiliary table that is foldably installed on the side of a workbench, counter table, etc. when used horizontally. The present invention relates to a support device that can be held.

[Conventional technology]

Foldable auxiliary tables are convenient because they can be folded up when not in use, make effective use of installation space, and allow the table to be used for multiple purposes.
Widely used.

Conventionally, as a support device for this foldable auxiliary table, one having a structure as shown in FIG. 8 is widely known.

That is, locking members 2 having a U-shaped cross section and having locking grooves 2a facing diagonally outward and upward are fixed in parallel to the front and back of the upper part of the side plate 1a of the table 1. The locking member 2 is pivotally supported at the upper end thereof so as to be rotatable between a horizontal use position and a vertical folding position along the side surface of the side plate 1a.

On the underside of the auxiliary table 3, there are vertical rods 4a on both sides.
A substantially U-shaped support rod 4 in which a horizontal rod 4b and a horizontal rod 4b are continuously formed is swingably provided, and the horizontal rod 4b at its lower end is inserted into both locking grooves 2a as shown by the two-dot chain line in the figure. By fitting, the auxiliary table 3 is held horizontally.

In a support device having such a structure, when the auxiliary table 3 is lifted upward or an object hits it and it springs upward, the support rod 4 falls out of the locking groove 2a and the auxiliary table 3 was folded suddenly, and there was a risk that objects placed on it would fall or fingers or fingers could be caught.

In order to prevent this, the groove width of the locking groove 2a may be made slightly narrower to tightly fit the support rod 4, or the elastic member D may be supported as shown in FIGS. 9A and 9B. Attach to horizontal rod 4b of rod 4, and attach side plate 1
An improved method has been taken in which the supporting rod 4 is brought into pressure contact with the locking groove 2a, and its elastic repulsive force tightly locks the support rod 4 and the locking groove 2a.

[Problem that the invention attempts to solve]

In the above-mentioned improved support means, since both support rods are fitted into the locking grooves while being pressed,
In addition to requiring extra force, in the former case, the locking condition becomes loose due to wear of the locking groove and support rod after long-term use, and in the latter case, the elastic material deteriorates and the locking condition becomes loose. There was a problem in that the force was weakened and there was a lack of certainty in preventing detachment.

This invention was devised to solve the above problems, and allows the support rod to be engaged and disengaged with a simple operation.
Moreover, it is an object of the present invention to provide a support device that can safely and reliably support an auxiliary table when in use.

[Means for solving problems]

Specific measures to solve the above problems are as follows:
A locking groove facing outward and upward is provided on the side of the table body, and an auxiliary table that can pivot between a horizontal use position and a vertical folding position is provided, and the auxiliary table swings on the underside of the table. In a support device that supports an auxiliary table in a horizontal position by fitting a horizontal rod at the lower end of a freely movable support rod into the locking groove, the vertical rod is moved outside the locking groove. A movable locking metal fitting is provided, and when the locking metal fitting moves downward, at least a part of the locking metal fitting is located outside the horizontal rod fitted in the locking groove, and the horizontal rod is prevented from coming off. It is characterized by a stop.

[Effect]

When the horizontal rod of the support rod provided on the lower surface of the auxiliary table fits into the locking groove of the locking member and the auxiliary table is in the horizontal use position, when the locking fitting is slid downward, This lower part is located on or comes into contact with the front and outside of the horizontal rod, thereby preventing the horizontal rod and therefore the support rod from falling out of the locking groove.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 7.

The same members as those in the conventional example shown in FIG. 8 will be described with the same reference numerals, and only one side of the locking members 2 provided in the front and rear will be described.

1 to 3 show a first embodiment of the present device, in which a locking member 2 having a U-shaped cross section fixed to a side plate 1a of the table body has predetermined positions on its left and right right angle portions 2b. , a locking groove 2a facing diagonally outward and upward
is formed in the U-shaped portion near this locking groove 2a,
A bracket 5, which is formed by bending the upper part of the flat plate outward in an inverted U-shape, is fixed with a bolt 6 that passes through the side plate 1a and the locking member 2.

The bent side surface 5a of the bracket 5 has a handle 7a whose upper part is bent outward at right angles, and an elongated hole 8 formed over a predetermined length above and below the center part. A stopper 7 is attached with a screw 9 so as to be slidable up and down.

The height H of the bent portion of the bracket 5 is, as shown in FIG. 3, when the locking fitting 7 slides downward.
It is determined so that it will not come into contact with the support rod 4 that is locked in the locking groove 2a of the locking member 2.

The width dimension of the locking fitting 7 is the right angle part 2 of the locking member 2.
It is slightly smaller than the internal dimension between b, and therefore,
When the locking fitting 7 slides up and down, the locking member 2
acts as a guide member and prevents wobbling.

In order to operate the support device in the above configuration, as shown in FIGS. 2 and 3, the locking fitting 7 is
Holding a and sliding it upwards, fitting the support rod 4 into the locking groove 2a of the locking member 2, and then releasing the handle 7a, the locking fitting 7 will slide downward due to its own weight and become horizontal. It stops at the front and outside of the rod 4b.

This causes the auxiliary table that is in use to
Even if the horizontal rod 4b springs up due to an external force, the horizontal rod 4b comes into contact with the locking fitting 7 and can be completely prevented from falling off from the locking groove 2a.

Moreover, if it is desired to remove the support rod 4 from the locking groove 2a, it is sufficient to hold the handle 7a of the locking fitting 7 and slide it upward to open the front part of the horizontal rod 4b.

Next, another embodiment of the present invention will be described.

4A to 4C show a second embodiment of the present device, and the bracket 5 has almost the same shape as the first embodiment except that the height H of the bent portion is slightly higher. Both sides of the locking metal fitting 7 are bent inward at right angles from the handle 7a portion to the lower end to form a guide portion 7b.

As shown in Figure B, this guide 7b slides up and down in sliding contact with the outside of both right angle portions 2b of the locking member 2, and when it slides downward, its lower vertical edge is in the locking groove. The supporting rod 4 is located in front of the horizontal rod 4b fitted into the locking groove 2a, and similarly to the above, the supporting rod 4 is prevented from falling off from the locking groove 2a.

Next, a third embodiment of the present device will be described with reference to FIGS. 5A and 5B.

In this embodiment, the height dimension H of the bent portion of the bracket 5 is reduced, and a locking portion 7c having a curvature approximately the same as the diameter of the horizontal rod 4b is provided at the lower part of the locking fitting 7 that engages with the bent portion.
It is formed by bending it.

When the locking fitting 7 slides downward, the locking portion 7c comes into contact with the upper front side of the horizontal rod 4b fitted in the locking groove 2a, thereby preventing the support rod 4 from falling off.

Next, a fourth embodiment of the present device will be described with reference to FIGS. 6A and 6B.

The height dimension of the bent portion of the bracket 5 is the same as that of the second
Similar to the embodiment (FIG. 4), slightly wider guides 7d are formed integrally with the locking member 7 on both sides of the locking member 7 and slidingly contacting the outside of the locking member 2.

Below both guides 7d is an inverted U pointing vertically upward.
A letter-shaped groove 7e is formed, and this groove 7e has a depth that allows the horizontal rod 4b to be fully fitted therein, and a size that allows easy engagement and disengagement.

When the locking fitting 7 is slid downward, both grooves 7e are connected to the horizontal rod 4b fitted in the locking groove 2a.
By straddling the support rod 4 from above, the support rod 4 is prevented from falling off.

Next, a fifth embodiment of the present device will be described with reference to FIGS. 7A and 7B.

In this embodiment, the above-mentioned bracket 5 is abolished and the locking metal fitting 7 is directly connected to the locking member 2, and the locking metal fitting 7 is bent outward in a substantially U-shape. A handle 7f is integrally formed on the lower side thereof, and a locking portion 7g whose end portion is bent downward with a curvature approximately equal to the diameter of the horizontal rod 4b is integrally formed on the upper side.

8 is the same elongated hole as in each of the above embodiments, and the locking metal fitting 7
is fixed to the side plate 1a and the locking member 2 by a bolt 10 inserted through the elongated hole 8 so as to be vertically slidable.

Horizontal rod 4 fitted into the locking groove 2a of the locking member 2
When the locking metal fitting 7 slides downward, the bent end of the locking portion 7g comes into contact with the upper front of the horizontal rod 4b, thereby preventing it from falling off.

In each of the above-mentioned embodiments, the pair of locking members can sufficiently perform its function even if only one locking member is used, but it becomes more complete when provided at the front and back.

Further, in addition to being provided on the locking member, it may be provided on the side plate 1a of the table main body at the intermediate portion of both support members.

[Effect of idea]

According to the support device of the present invention, it is possible to provide an inexpensive support device because it is only necessary to add a simple locking fitting without making any major design changes to the conventional support device.

In addition, the support rods can be engaged and disengaged with a simple operation, and even if the auxiliary table in a horizontal state of use springs up, there is no risk of the support rods falling out of the locking grooves. Damage to the placed items can be prevented.

Even if the locking groove or the support rod is worn out over a long period of time and the fitting state becomes slow, the locking fitting and the support rod are in contact with each other, so they are completely prevented from coming off.
