Abstract

The present invention relates to tents that have a collapsible structure that have the advantage of being expandable and stored in a reduced size. Said tents have the ability to retract and expand to create a structural network, which forms a compact assembly.

Description

COLLAPABLE TENT Inventor: Mr. Jorge Videgaray Zapata, of Mexican nationality, residing at: Alencastre 235-701, Col. Lomas Virreyes, 11000 Mexico, D.F.

D E S C R I P C I O N The present invention relates to temporary or movable tents, which have a collapsible structure. Said tents in their collapsible form have the advantage of being able to be stored in a reduced size and at the same time they can be expandable, providing a large space sheltered from their elements and providing privacy to the user.

The structure is composed of moving parts in the form of stringers that in turn form an "X", which provide the ability to retract and expand and create a structural network, which at the time of contracting forms a compact set that reduces to a quarter of the expanded structure.

The stringers are joined to each other by their middle part and the friction is reduced by means of a central sheave, protecting this joint in turn with "U" shaped sheets that reinforce the center of these joints.

The stringers are also joined with telescopic tubes that in turn form the supports of the structure. These supports consist of three pieces which act as a base, the internal part or internal support is joined to a triangular base so that this way you get more contact with the ground and its height is adjustable to be able to adapt to the relief of the ground.

The distribution of the structure seen from above succeeds in adopting a window shape; the structure has the modular growth capacity, in this way different sizes and shapes can be achieved.

In its central part, the collapsible tent has a telescopic pole, which lifts the central part of an awning, thus achieving tension the awning attached to the structure and at the same time avoid forming water pockets. The awning and the structure are held together when the structure collapses, in order to facilitate its transport.

The structure is kept upright by means of insurance, which are found in each support and in the central post.

To be able to collapse the structure you simply need to press the locks, and thus allow the race of the sliders of each support.

Detailed description of the drawings.

As illustrated in fig. 1, the tent is composed of a retractable telescopic structure 10 and an awning 11, which covers the structure 10. The side view of the structure 10 is illustrated in fig. 3. The structure includes at least four main supports 13, and twelve support scissors 18, which together form, seen from above, what looks like a window with a cross in between as shown in fig. 4, and a central support post 23, located in the center of the tent. Each main support 13 has another inner telescopic support 14. Each scissor 18 is formed by two independent tubes joined at the center by a screw 20, a central roller 21, a central nut 22, and a "U" shaped sheet. In this way each main support 13 can expand and contract, and each scissor 18 can be opened and closed, around its central point, thereby facilitating the opening and closing of the tent.

The awning 11 and the structure 10 are fixed by means of screws passing through the union of the central scissors 18 (see Fig. 7) towards the eyes 12 made in the awning 11 and a nut 22, which is only linked to through the upper joints of the scissors 18, in order to achieve the fastening of the awning 11 and the structure 10. In this way the awning 11 can easily be placed and removed from the structure 10. The union of the central scissors 18 is achieved from an angle of 90 degrees 27, which in turn is fastened by means of screws 20 and nuts 22, to the outer and inner scissors 18.

As illustrated in Figure 5, each support 13 has a slider 25, (see Fig. 9), to be able to join the scissors 18 to the supports 13.

Each slider 25 has a perforation 26 so that the slider is secured. A metal lock 28 is provided in each upper part of each support 13, when the slider 25 reaches the top of the support 13, with the scissors 18 fully open, the metal lock 28 is actuated and inserted into the perforation 26 of the slider 25 thus ensuring the open position of the structure 13.

Additionally, as shown in figures 5 and 6, the central support 23, consists of a central bar and a slider 25, which has a bore 26, which acts in the same way as the slider 25. The bar central 23 consists of a metal lock 28 and a mushroom-shaped plate in its upper part 24, this as a whole forms an internal projecting device of the structure 13.

The support 23 is connected to four pairs of the scissors 18, and in four directions by means of a slider 25; in this way when the structure 13 opens the support 23, it will lift the central part of the awning 11, and it will be stretched to make it rigid and avoid the possibility of hanging the awning 11 and forming pockets of water.

In figure 9, the lower part of the supports 13 is illustrated and it can be seen that it is joined to a triangular base 27, and thus greater contact and stability of the assembly is achieved. Likewise, a series of perforations 16 are illustrated, which serve to regulate the height of the internal main support 14, by means of a metal lock 28, which is inserted in each of the perforations 16, when the inner support 14 slides.

In this way the awning 12 is secured to the structure 13 in an easy and safe way, thus achieving the power to assemble and remove the awning 12. All this together, creates a rigid and secure tent.

Claims (1)

1. CLAIMS FIRST.- A collapsible tent composed of moving parts in the form of spars which are retracted and expanded to create a structural framework. SECOND.- The collapsible tent of claim No. 1, which form a compact set creating a structural network. THREE.- The side members according to claim 1 that are joined together by a middle part to reduce friction through a central pulley and by telescopic tubes that in turn form the supports of the structure.
