Telescopic shelter system

Abstract

A telescopic shelter system comprises two pairs of guide rails having a pair of parallel outer rails and a pair of parallel inner rails arranged at an inner side of the outer rails, a plural of shelters comprising two side walls facing each other and a roof connecting at the top of the two side walls, the two side walls and the roof are tapered at one end of the shelter, each shelter arranged on the guide rail in a row, a plural wheels provided at each lower portion of two side walls of each shelter along movement direction of the shelter, having a pair of first wheel running on the outer rail and a pair of second wheel running on the inner rail, and a motor mounted on the shelter for providing a clockwise-counterclockwise movement of the wheel.

Description

1. FIELD OF THE INVENTION [0001] The present invention relates to a shelter system which is used at an outdoor workshop for large structures, such as an airplane shed, or gymnasium. More particularly, the invention relates to a telescopic shelter system in which several shelter sections are arranged in a row, and can be retracted or expanded, if necessary. 2. BACKGROUND OF THE INVENTION [0002] Since large articles are used at a shipyard, or a steel fabrication plant, the manufacturing process is held mainly outdoors depending the working environment and it also adds convenience of transfer and handling. [0003] A large vessel structure has a heavy weight and an extra large size which varies from few to several meters. The transfer and handling of the production is achieved by a large crane, which also includes a welding process, which is better suited for the outdoor environment. [0004] Therefore, in a shipyard, work is sometimes more difficult due to bad weather such as snow, rain a...

AI Technical Summary

Benefits of technology

"The present invention provides a telescopic shelter system that allows several shelter sections to be retracted or expanded as needed, reducing the space required for the shelters and making efficient use of the workshop. The system includes guide rails and shelters with wheels and a motor for easy movement. The shelters are made up of a frame assembly and an enclosure covering the side walls and roof. The system can be used without extra rails for transferring production and can be easily telescoped under clear weather. The invention improves the convenience, safety, and reliability of the shelter system and increases space efficiency in workshops."

Problems solved by technology

Therefore, in a shipyard, work is sometimes more difficult due to bad weather such as snow, rain and wind.

Moreover, work is frequently cancelled.

Since the width of respective shelter sections “S” of the conventional art is the same, each shelter section must be arranged in a row, which brings a problem that the space occupied by the shelter section becomes excessively large.

However, when many shelter sections are used, they must be arranged in a row, and a space the same volume as the shelter section is allotted to the other shelters, which leads excessive space.

Furthermore, in the case that the product “W” to be moved is disposed at the middle of the shelter section array, several shelter sections must be moved successively in order to pick up the product “W”, which brings another problem.

Even though the weather is good, work is performed under poor working condition, which leads other problem.

Furthermore, a problem issued by the shelter section's placement on the rail is shown in FIG. 2.

Due to this heavy weight the walls have a tendency to spread away from each other.

Both side walls “P” can not maintain a vertical configuration due to its own weight.

Therefore, it is very difficult that the shelter section is placed on the guide rail “R” because the wheel installed at the bottom end of the shelter section “S” is out of alignment with the guide rail “R”.
