Description

[Detailed description of the invention] [Industrial application field] This invention can be used, for example, as a temporary product storage area or display stand in a product sales floor, and when not in use, it can be made low-volume and stored in a corner. This is about the table.

[Conventional technology and its problems]

As a table that can be made low in bulk when not in use,
One pair of opposing leg rods are supported on both sides of the bottom surface of the top plate so that they can swing freely only in one direction of the top plate, and the other opposing leg rod is
The pair of leg rods is a telescopic leg rod consisting of an inner and outer double pipe, with a horizontal crosspiece between the outer pipe and the leg rod on one side, and a diagonal support crosspiece between the middle part of the inner pipe and the top plate. There is (Jitko Sho 54-24802).

The above-mentioned conventional table has a top plate that is tilted so that the leg rods on both sides are close to each other, so that the table can be folded vertically and flatly.

However, when a table having this structure is used, that is, when a heavy object is placed on the table with the leg levers on both sides separated from each other, the leg levers may wobble and become unstable.

Therefore, the purpose of this invention is to provide a table that is stable and foldable by having both leg rods supported by leg crosspieces on the lower side.

[Means for solving problems]

In order to solve the above problems, this invention has casters on the underside, a pair of parallel leg bars on the left and right, one end of which is fixed, and the other end is telescopic and can be locked at least in an extended state. The telescopic pillars are installed on the fixed pillar side so that they can be folded down freely, and the upper ends of both pillars are equipped with arms that face in the opposite direction to the direction in which the telescopic pillars lie down. The table is swingably supported on the side of the top support.

[Effect]

When storing a table while in use, by unlocking the telescopic pillars, the pillars will contract under the weight of the top plate, causing the top plate to tilt and the telescopic pillars to be retracted. As it contracts further, it tilts toward the fixed pedestal, and the top plate becomes a hanging position.

〔Example〕

In Fig. 1 (side view) and Fig. 2 (front view), 1 is a pair of parallel leg bars on the left and right that have casters 2 on their lower surfaces, 3 is a fixed pedestal that stands on one end side of the leg bar 1, and 4 is a fixed leg post that stands on one end of the leg bar 1. This is a telescopic pedestal installed on the other end side of the pedestal 1 so as to be freely foldable toward the fixed pedestal 3.

The pedestal 4 consists of an outer pipe 5 on the side of the pedestal 1 and an inner pipe 6 passed through the outer pipe, and a lock pin attached near the upper end of the outer pipe 5 while extending to the same length as the pedestal 3. 7 to lock the inner pipe 6.

FIG. 3 shows the lock pin 7. The lock pin 7 can freely move forward and backward within the cylindrical body 8 attached to the outer pipe 5, and has the resilience to constantly advance toward the inner pipe 6 through the intervention of a coil spring 9. When the hole 10 formed in the lock pin 7 matches the hole 10 formed in the lock pin 7, the tip of the lock pin fits into the hole 10, and by pulling the knob 11 at the rear end of the lock pin and moving the inner pipe 6 in either direction, the lock pin can be removed. remains in a backward position.

12 is a hinge fitting for attaching the pedestal 4 to the pedestal 1.

Arms 13 and 14 are provided at the upper ends of the pillars 3 and 4 in a direction opposite to the direction in which the pillars 4 are laid down.
It is supported by 8.

As an example, the arm 14 of the pedestal 4, which is extendable and retractable, is shown as a link arm that is separate from the inner pipe 6 and connected by a shaft 19.

Reference numeral 20 denotes a horizontal beam extending between the left and right fixed pillars 3, 3.

Reference numeral 21 denotes a horizontal beam extending between the upper ends of the left and right outer pipes 5, 5 of the extensible pillar 4.

As shown in solid lines in Figure 1, this table is ready for use by standing the telescopic column 4 in a straight line and fixing both the inner and outer pipes 5 and 6 with lock pins. By releasing the fixation and contracting the pedestal 4, the top plate 15 tries to hang down as shown by the chain line in the figure, and the pedestal 5 also falls down toward the pedestal 4.
In this state, the storage floor area can be reduced by fitting a plurality of tables along the side of the leg frame 1 of each table.

〔effect〕

By using a table based on this idea, the following effects can be obtained.

(1) One pair of left and right fixed pillars on one side, and one pair of left and right pillars on the other side.
Since the pair of telescopic pedestals are supported by the parallel left and right pedestals, there is no risk of the pedestals wobbling even when a heavy object is placed thereon in use.

(2) When the telescopic pedestal is unlocked, it contracts under the weight of the top plate and falls down to the fixed pedestal side, causing the top plate to hang down as well, making it possible to make multiple tables smaller. Can be stored within the floor.
