Description

[Detailed description of the invention] This invention is an accordion used for vehicles, garages, warehouses, etc., which has inverted U-shaped support rods connected by a parallel link mechanism, and whose hood can be extended and contracted in a bellows shape. Regarding arches.

In conventional accordion arches, when folded, the canopy hangs down between the support rods in a folded manner, which is a drawback as it becomes a hindrance when putting in and taking out stored items.

In order to reduce the sagging of the top when folded, it is possible to reduce the pitch of the support rods when the arch is expanded, but this requires a large number of support rods and has the disadvantage that the arch becomes wider when folded. There is.

This idea was designed to reduce the pitch of the support rods to reduce the sagging of the hood when folded, but to eliminate the sagging of the hood itself.The following is an example of an accordion arch for a vehicle. I will explain based on this.

In FIG. 1, 1 is a torii gate, 2 is a gate, and a rail 3 is attached to the gate 2 along the longitudinal direction.

Reference numeral 4 denotes a support rod that is approximately inverted U-shaped, and the other support rods, excluding the fixed support rod attached to the torii gate 1, are slidably engaged with the rail at both ends of the legs in order to run along the rail 3. are doing.

Reference numeral 5 denotes an intermediate support having the same shape as the above-mentioned support rod 4 and placed in parallel between the support rods, and connected to the support rod 4 by a parallel link 6 (
(See Figure 2), when the support rod 4 runs along the rail 3,
The link bends and stretches while moving the intermediate strut 5 up and down, and as a result, the distance between the support rod and the intermediate strut expands and contracts, opening and closing the arch.

7 is a roll pivotally attached to the foot end of the intermediate support;
When the arch expands, the intermediate strut descends and hits the upper surface of the rail 3, thereby restricting the expansion of the arch beyond a predetermined level.The intermediate strut also functions as a strut that supports the canopy, and its height is It is lined up at the same height as support rod 4.

Therefore, the lifting of the intermediate support 5, which moves up and down due to the bending and stretching of the link mechanism, results in a projecting movement onto the support rod 4.

8 is the hood. FIG. 3 shows another example of the link mechanism, in which a pair of links 9°9, one end of which is overlapping and pivotally attached to the support rod 4, is pivoted at the other end to the intermediate support 5 at a distance from each other vertically. The lower shaft is designed to slide within the vertical groove 10 of the intermediate support, and when the support rod runs along the rail, the diamond-shaped link bends and stretches while moving the intermediate support 5 up and down. It looks like this.

This invention is constructed as described above, and since the rising intermediate struts protrude above the support rods and thereby push up the top, the top does not hang down in folds between the support rods when folded.

In addition, when deployed, the intermediate strut hits the rail, preventing it from descending, restricting it from being deployed beyond a predetermined amount, and in this state, the intermediate strut functions as a strut that supports the canopy. The above-mentioned intermediate support constitutes a link mechanism that expands and contracts the arch, and uses this link mechanism to move it up and down. There is no need to provide a new mechanism to move it up and down (it has the advantage that it can be easily applied to conventional accordion arches).

Claims (1)

[Scope of utility model registration request] A support rod 4 having an inverted U shape is supported by slidably engaging a pair of rails 3 arranged in parallel with each other.
and the support rods 4 are arranged alternately on the rail 3, and the support rods 4
An inverted U-shaped intermediate support 5 having substantially the same shape as the support rod 4 is connected to the intermediate support 5, and the distance between the support rod and the intermediate support is expanded or contracted by bending and stretching as the intermediate support moves up and down. Consisting of a link mechanism 6.9, the intermediate support that descends due to the extension of the link mechanism is prevented from descending by hitting the rail 3, becoming supported by the rail and preventing further extension of the link mechanism. An accordion arch is shaped like this, and its height is the same as the support rod when it hits the rail.
