Description

[Detailed Description of the Invention] The present invention relates to an extendable building used as an automobile garage or the like.

In this type of building, when the canopy is folded and reduced, there is a risk that the lower end of the hood that hangs down may get wedged between the rails and rollers, so the undercarriage must be constructed with a mechanism that can prevent this jamming.

Therefore, the rollers installed at the lower ends of the struts are arranged so as to run inside C-shaped rails laid in the running direction, and the rollers are covered by the C-shaped rails to prevent the lower ends of the hood from being bitten. There is.

Conventionally, rollers configured as described above have been used, for example, in
As described in Publication No. 9-45048, on the lower side of the column,
There is one in which a roller is supported via an axle and the roller is positioned inside the C-shaped rail.

However, in this building, the contact area between the roller and the rail,
In other words, the position of the center of gravity of the ground contact portion and the support column are misaligned, resulting in unstable cantilever support, which places a large burden on the axle.

Furthermore, since the C-shaped rail is located on the side of the support column, it becomes unsightly and obstructive whether it is installed inside or outside the building.

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, it is an object of the present invention to provide a telescoping building in which the rollers are located directly below the supports.

That is, in the building according to the present invention, the lower part of the pillar supporting the canopy is composed of two pillars, the lower ends of which are connected,
A pair of rollers is installed via an axle provided from the center of the lower ends of the two pillars downward to the left and right so that the rollers are located directly below each of the pillars, and the rollers are installed in a C-shape with the opening sides facing each other. It is configured to be placed inside the shaped rail.

In buildings constructed in this way, the pair of rollers are located directly below the pillars, so the pillars can be stably supported, and the C-shaped rails do not protrude when the canopy is extended. It also has an excellent aesthetic appearance.

This will be explained below based on the illustrated embodiment.

In the embodiment shown in the drawings, a building is constructed that can be used as a garage for automobiles.

This building has a semicylindrical exterior as shown in the first figure, and supports a canopy 2 with a plurality of inverted U-shaped supports 1, 1, . . . .

Each of the pillars 1, 1, . . . is supported by rails 3, 3 so as to be freely movable, and extendably and retractably supports the hood 2 fixed on the pillars.

The pillars 1, 1, . . . have both legs branched into two in a direction perpendicular to the running direction, and are connected at their lower ends.

Axles 4, 4 are provided on the left and right sides in an L-shape from the center of the branched side legs 1a, 1a at the lower ends of each of the legs of the support columns 1, 1, . It supports rollers 5,5.

The rollers 5, 5 are secured on both sides by collars or the like on each axle 4, 4 to prevent the wheels from falling off due to rolling, and are located directly below the branched supports 1a, 1a, respectively. has been done.

The rails 3 are formed by half-tone C, and are laid in a pair with their opening sides facing each other, and are laid on the foundation in the running direction.

Further, in order to support the inverted U-shaped pillar side legs so that they can run freely, these rails are laid out in parallel at regular intervals.

With respect to the rails 3, 3, the rollers 5, 5 are
It is fitted inside the 0 character.

The fitting arrangement can be performed by inserting from the end of each rail, and the open end can be covered by a stop plate after the roller 5 is inserted.

The axle 4 moves within the opening of the rail 3, and the rollers 5, 5 contact the inner bottom surfaces of the rails 3, 3 and rotate.

In a building configured in this way, the ground plane of the roller is directly under each of the two branched legs of the support, so the center of gravity of the support and the center of the ground contact part perfectly match, and the two Since the rollers work together to distribute the load, the load on the axle is reduced, resulting in a building with excellent stability and durability.

In addition, the C-shaped rail is housed at the bottom of the support leg and is covered by the hood, which is supported on the outside of the car via the support, which prevents the hood from digging in and prevents unsightly rails from being exposed. The result is an excellent aesthetic appearance.

In addition, the rollers inserted into the C-shaped rail can be easily removed from the end of the rail, making it easy to change the installation location, and even when the building is moved, the rollers can be moved without the rail. You can walk on the foundation.

Incidentally, in the diagonal embodiment, a building having a semicylindrical shape was constructed, but even if this structure is constructed as a mechanism for supporting a tent on a cantilever, it is highly stable and highly practical.

As described above, the building according to the present invention is highly stable and durable due to its extremely simple mechanism, and has an excellent aesthetic appearance, resulting in great practical benefits.
