Abstract

Apparatus for suspending a tent comprising support poles at each corner thereof, a top wall of the tent being supported by a center frame member supported by the support poles to thereby omitting a main center pole. The support poles are connected together by support beam which acts as rain gutters and the support poles serve as vertical rain conducts.

Claims

1. A support structure for a tent comprising in combination:

a support pole erected at each corner of the tent;

a beam member extended between the upper end of each said support pole for sustaining a hem of the tent;

a bearing member for uplifting the center of the tent;

a stay rib diagonally extending between said bearing member and the upper end of a support pole; and

shaft members extended between the middle part of said stay rib and the lower end of said bearing member with a turnbuckle interposed therebetween.

2. In a structure as defined in claim 1, said support pole consisting of a pipe like material and constituting a vertical conduit, a bulge and a flange being integrally formed on said support pole at the upper end thereof.

3. A structure as defined in claim 2 said flange having a concave groove for receiving a terminal of a beam member and a terminal of a stay rib, said flange also comprising a flat surface for securing the projections thereto provided on said terminals.

4. In a structure as defined in claim 1, said beam member consisting of a pipe like material, a slit being axially provided on said beam member, projections at right angles with said axial slit being provided at the terminal of said beam member.

5. In a structure as defined in claim 1, said stay rib consisting of a pipe like material and being provided at one end thereof with a pair of projections projecting at right angles with the axial direction and secured at the other end thereof to the bearing member at the center of the tent.

6. A structure as defined in claim 1, wherein said bearing member further comprises an outer cylinder, an elevatable inner cylinder that is inserted into said outer cylinder and is provided with a frame member at the top thereof for uplifting the tent and a male screw engaged with the inside of the inner cylinder for elevating said inner cylinder, a mounting piece for securing the other end of the stay rib being provided on tHe outside of the middle part of the outer cylinder, a projection for securing one end of a shaft member being provided at the lower end of the outer cylinder.

7. In a structure as defined in claim 1, said beam member and said hem being engaged to each other by inserting into the slit of the beam member the bulging rib of the tent edge formed by hemming said edge with a string member enclosed thereinside, said bulging rib being adapted to be constricted between the edge of the slit of the beam member and the peripheral walls of the annular members fitted into said slit.

8. In a structure as defined in claim 1, said beam member being engaged with said tent hem by rings spaced on said hem, said rings being engaged with hooks of arcuate plates secured to the inside of the slit of the beam member.
