Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a foldable and movable table tennis table.

[Conventional technology]

Typical table tennis tables are often configured with two tables (tops) installed one after the other, but this takes up a certain amount of space and the room cannot be used for other purposes, so the table tennis table can be folded and moved. It is known that it is composed of

The foldable table tennis table has two top plates connected by a hinge, each having legs near the hinges and at both ends that can be folded via links that can move parallel to the top plates. The legs near the hinge are equipped with casters, and the top plate can be folded in half vertically about the hinge.

According to this conventional example, both top plates are folded vertically in parallel, the legs are folded and suspended almost parallel to the top plate, and the whole is supported on the floor by the legs near the hinges. , and can be moved on the floor via casters provided on its legs. On the other hand, when both top plates are expanded, the legs rotate in a direction perpendicular to the top plate via the links and open, and the legs near the hinges are supported on the caster floor.

[Problem that the invention attempts to solve]

According to the above-mentioned conventional folding table tennis table, when the table tennis table is opened and can be used as a table tennis table, the legs near the hinge are supported on the floor by casters, so the legs are easy to move and stable. It's bad. In other words, the legs installed at the ends of the top plate do not have casters, so the contact resistance with the floor is high, but the casters have low contact resistance and roll easily, so if an impact is applied to the plate or its legs, it will immediately Under that influence, it will not be displaced. Therefore, there is a problem in that the top plate is subtly affected by the swinging of the legs due to the slippage of the casters, which may adversely affect the competition.

[Means for solving problems]

In order to solve the above problem, the present invention has two top plates connected by a hinge, each having foldable legs near the hinge and at both ends via links that can move parallel to the top plate. In the table tennis table, the legs in the vicinity of the hinges are provided with casters, and the top plate is foldable in half in a vertical position about the hinges, and the legs in the vicinity of the hinges are provided with casters in the longitudinal direction. To provide a table tennis table provided with a slidable auxiliary leg and an interlocking rod having one end connected to the auxiliary leg and the other end connected to the link.

[Effect]

According to the above structure of the present invention, when the top plate is folded vertically, it can be moved on the floor by the casters, but when the top plate is expanded horizontally, the casters are lowered onto the floor by the action of the links and interlocking rods. The casters can be lifted up, and the top plate can be stably supported and fixed by the legs that touch the floor.

〔Example〕

The present invention will be explained below based on an illustrated embodiment.

FIG. 1 is a side view of the table tennis table in a used state, and FIG. 2 is a side view of the table tennis table in a stored state.
In the figure, a table tennis table 1 with a symmetrical configuration
, two top plates 2, 2 having the same configuration are supported by frames 3, 3, respectively, and a hinge portion 4 is provided at the contact portion of the top plates 2, 2, so that both top plates 2, 2 are supported by frames 3, 3, respectively. , 2 can be folded. The frames 3, 3 also have links 5, 5 interlocking with the hinge portion 4.
Can be folded through. The frame 3 has leg portions 7 rotatably supported below the end of the top plate 2 via a bracket 6, and a leg portion 7 rotatably supported via a bracket 8 at the lower part of the top plate 2 near the hinge portion 4. an interlocking rod 1 which is pivoted on the legs 7 and 9, extends parallel to the top plate 2, and is pivotally supported on a bracket 10 protruding from the top plate 2 near the hinge portion 4.
It consists of 1 and 12. The interlocking rods 11 are rotatably supported on the hinge portion 4 by shafts 13, and have stop surfaces 14 and 15 that abut against each other.

On the other hand, the leg portion 9 is made of a hollow cylinder, and an auxiliary leg 16 is inserted into the hollow cylinder, and a long hole 1 from which a pin 17 protruding from the auxiliary leg 16 is projected.
8 is formed. One end of an interlocking rod 19 is pivotally supported by the pin 17, and the other end of the interlocking rod 19 is pivotally supported by the interlocking rod 12. The leg portion 9 is shorter than the leg portion 7, and a caster 21 is suspended from the lower end of the leg portion 9 via an arm 20 projecting laterally. Reference numeral 22 denotes a shoe that is screwed onto the lower ends of the leg portion 7 and the auxiliary leg 16 to allow fine adjustment of the height.

Next, the operation of the above embodiment will be explained.
As shown in FIG. 1, when in use, the top plates 2, 2 are in a horizontal position, and the legs 7, 9 are connected to the links 5,
5, it is supported on the floor in a vertical position by the top plates 2, 2. At this time, the caster 21 is lifted off the floor surface and has no load. Therefore, the top plates 2, 2 are not adversely affected by the casters 21. As shown in FIG. 2, in the stored state, both the top plates 2, 2 and the legs 7, 9 are parallel to each other due to the action of the links 5, 5, and are in a substantially vertical position. Due to the movement, the interlocking rod 12 pulls up the interlocking rod 19 and the auxiliary leg 16 retracts into the leg part 9. Therefore, when the auxiliary legs 16 are retracted into the legs 9, the casters 21 come into contact with the floor and support the entire load of the table tennis table 1. In other words, in the state shown in FIG. 1, if both ends of the top plates 2, 2 are lifted upward and rotated around the hinge part 4, the legs 7 will fall down due to the action of the links 5, and the interlocking rods will 19 acts to pull up the auxiliary leg 16, while the caster 21 is pushed down, resulting in a relative movement, and at the same time the caster 21 touches the floor, the shoe 22 of the auxiliary leg 16 leaves the floor. In this way, the entire table tennis table 1 is caster 2.
1, it can be folded up so that it can be moved on the floor. In addition, when changing from the state shown in FIG. 2 to the state shown in FIG. 1, an operation opposite to the above-mentioned folding operation is performed.

[Effect of idea]

According to the present invention described above, when the table tennis table is folded and movable via the casters and is opened for use, the interlocking rod that is linked to the link brings the auxiliary legs into contact with the floor surface, and at the same time the casters Since the table is made to float off the floor, the casters do not support the load of the table tennis table when in use. Therefore, the casters do not roll and make the tabletop unstable during a competition, and when folded, the auxiliary legs lift off the floor at the same time as the casters touch the floor, so the table tennis table can be used with casters. can be supported movably on the floor, and indoor spaces such as gymnasiums can be used effectively.
