Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a folding chair storage device that stores a folding chair when not in use and exposes the folding chair when in use so that the folding chair can be used. .

[Conventional technology and its problems]

Various types of folding chair storage devices configured to store a folding chair when not in use and expose the folding chair when in use so that the folding chair can be used have been conventionally proposed. However, there are inconveniences such as a tendency of insufficient strength and an increase in bulk more than necessary.

For example, in a storage device for a folding chair having a structure as shown in FIG. 3, it is assumed that the storage box 1 has the folding chair 2 inside and the upper lid 3 at the upper end thereof. Considering the case where the upper lid 3 is used as a so-called passage portion, there is a disadvantage that sufficient strength cannot be obtained.

That is, the upper lid 3 includes a main lid 30 and a sub lid 31 so that the upper chair 3 can be opened and closed in a so-called double door mode. In particular, the folding chair 2 is connected to the sub lid 31, and The folding chair 2 is formed so as to be turned up and down following the opening and closing operation of the sub-lid 31.

Therefore, considering that the main lid 30 is used as a so-called passage portion when the main lid 30 is closed, the swinging end 30a is locked to the storage box 1 side by an appropriate means when the main lid 30 is closed. It is necessary to be configured to

However, in the above conventional example, the main lid 30
Locking the swinging end 30a of the storage box 1 to the storage box 1 side means that
A stopper or the like 10 is provided on the side of the storage box 1 so as to hinder the raising and lowering and raising and lowering operations of the folding chair 2.

Therefore, when the stoppers 10 are provided on the storage box 1 side, the folding chair 2 is not obstructed in order to prevent the folding chair 2 from falling.
Only the provision of the stopper 10 having a light and vigorous structure is required. As a result, in the conventional example described above, sufficient strength cannot be obtained for closing the main lid 30 and using it as a passage portion. There is concern.

On the other hand, in the folding chair storage device having a structure as shown in FIG. 4, the main lid 30 forming the upper lid 3 is provided in the storage box 1.
Is fixed in advance at the upper end of the slab.

Only the sub lid 31 can be opened and closed, and the folding chair 2 is raised and lowered in a so-called upright state by the expansion and contraction operation of an actuator 4 such as a hydraulic cylinder provided at the lower end thereof.

Therefore, in the folding chair storage device shown in FIG. 4, the main lid 30 can be connected to the storage box 1 firmly, and therefore, the main lid 30 can be connected to the passage portion. There is an advantage that the strength required for use as the storage box can be easily secured, but since the storage box 1 is configured to store the folding chair 2 in a so-called upright state, the storage box 1 itself is extended downward. The disadvantage is that the entire device tends to be formed so large that the entire device becomes unnecessarily bulky.

The present invention has been made in view of the above-described circumstances, and has an object to provide a storage box with a predetermined strength necessary for using an upper lid connected to a storage box as a passage portion, and a device. An object of the present invention is to provide a folding chair storage device in which the whole is not excessively bulky.
