FIELD: construction.

SUBSTANCE: invention relates to the shelter to protect users against the external medium. Shelter comprises the inner front module, having a flat base and side walls, which extend from the base, and gateway, the outer front module slidably attached to the inner front module; in this case there is a seal hermetical by air between the inner front module and outer front module, besides the external front module has a front attachment portion, inner rear module, and outer rear module slidably attached to the inner rear module; in this case there is a seal hermetical by air between the inner rear module and outer rear module, besides the outer rear module has a rear attachment portion, by means of which the outer rear module is fixed to the front attachment portion of the outer front module, when the outer front module and inner front module are in the extended position, and the rear outer module and inner rear module are in the extended position, and the outer front module and outer rear module are attached, in this case the outer front and rear modules and the inner front and rear modules form the airtight chamber. In this case, each attachment portion is an outer flange, besides there is an outer seal between each attachment portion, when they are attached to each other. Thus, while in the compact state, the inner front flange of the inner front module and the front attachment portion of the outer front module are flat and separated, and spaced from the inner and outer rear modules. Besides the clamp is attached to the inner front module and outer front module when the inner and outer front modules are in compact condition for retaining the inner and outer front modules in compact state.

EFFECT: creation of compact and easily moved shelter.
