Abstract

Foldable sports chair, essentially characterized by having three columns (2) joined by separate studs (6) with threaded or not (7), secured at one end to each other and the other have the repeated blocker or nut (7) ) that has the particularity of being fixed at the other end, blocking the columns (2), without highlighting on the surface of these (2), achieving the impossibility of leaving or loosening of their alveoli fixed on the support columns (2). These limit its opening by the extension or length of the seat (1) which is flexible to facilitate its folding. (Machine-translation by Google Translate, not legally binding)

Description

Folding sports chair

Object of the invention

The present invention relates to a type of small seat, essentially oriented to sports use in field and beach, consisting of three bars or support tubes attached by its internal face, having two holes through by studs or bolts, one for each tube. These bolts are solidarity by one of its ends. The other end blocks the support tubes by nuts or other locking system. Area upper support tubes serve to fix the seat and the bottom performs the function of legs for support on the floor of the chair or bed, being able to fold and unfold carrying its upper part an equally folding seat and having a belt for transport, which has as innovation the following features:

a) The transport belt can be picked up and set semi-automatically in the desired position to Avoid dragging on the ground.

b) The joining system of the tubes or columns support has a locking system that prevents any highlight outside on its surface of the end of the bolt or of the nut, locking case of having thread, which avoids possible injuries to the user during their bearing, as well as greater attractiveness aesthetic and the inability to loosen the nut when registering with the same shape in the support tubes.

c) Ground support systems, which at settle, its legs occupy the maximum surface, thanks to the shape pointed when folded and maximum surface when deploys, distributing more proportionally the weight of the user in the ground, avoiding its sinking, also being able to have An anti-sinking disc

Description of the invention

The sports chair that is recommended is consisting essentially of three supporting elements or tubes joined by a system of three "studs" equally solidarity by one of its ends which cross each of their tubes. The asparagus free end is blocked by a nut or other locking system, being able to rotate said tubes on the mentioned studs. This nut is inscribed and formed inside the support tubes or columns without showing outward relief, which does not detract from its use with exterior protrusion if interested.

The carrying system of the sports chair, with tape or belt, prevents its drag on the ground once deployed, when using a pin with two or more openings where the carrying strap, with double entry in one of the fixing windows its position thanks to the user's hand semi-automatically, shortening or lengthening it as appropriate.

To prevent the sinking of the device subject to this invention in soft terrain, each support element and for its opposite end of the union with the seat, has a extensive ground contact surface, so that supporting elements will have a biased shape or will have a ring of greater surface than said columns or tubes.

Description of the drawings

To complete the description that is being performing and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive, as an integral part of it, a game of drawings, where illustrative and non-limiting are It represents the following:

Fig. 1 shows a representation in perspective with the sports chair deployed in the position of use.

Fig. 2 shows a representation in sports chair perspective in folded position, ready for transport

Fig. 3 shows in detail a representation in perspective of the joint stud system and the housing in its socket of the lock nut.

Preferred Embodiment of the Invention

As seen in the drawings presented the folding sports chair, object of the present invention, is It consists essentially of three support tubes or columns (2) joined together, when the available hole is crossed in each one of them, by means of two bolts or studs (6) integral with one of its ends, allowing the rotation of the support tubes (2) whose opening is limited by the seat (1), which is folding. To prevent the exit of the support tubes (2) from their corresponding studs (6), it has the unblocked end of a nut (7) which does not highlight its relief on the surface external of the support tubes (2) when housed inside the shaped socket containing said tubes (2), which you do not want say that they can also be blocking employees (7) that do not meet this requirement.

The upper part of the support tubes (2) it serves to anchor the seat (1) and the lower one acts as leg (8) to support the whole. The end of the leg wears as Novelty a biased surface, which when they are in deployed position presents the maximum surface to the ground where It settles. It can also carry an anti-sinking system consisting of a disc (9) of diameter greater than the tubes of support (2).

The sports chair carrying system presents as novelty some grooves, flexible or rigid (4) that controls the desired length of the conveyor belt (3), which goes anchored in its lower part to one of the legs (8) and the upper one to the grooves (4), whose central axis can be rigid or mobile, entering  by them and overlapping in such a way that when pulling the bearing tape (3), this is azoque.

In order to avoid unwanted opening of the sports chair, when in the folded position, has a belt or belt (5), which anchored to one of the support columns (2), hug the others (2), closing by means of their corresponding clip.

It is not considered necessary to extend this description, so that any subject matter expert understands the scope of the invention and the advantages thereof drift

The materials, shapes, size and layout of the elements will be susceptible to variation, as long as this does not imply an alteration to the essentiality of the invention.

The terms in this memory have been described, they should always be taken in a broad and non-limiting sense.

Claims (3)

1. Folding sports chair, essentially characterized by having three columns (2) joined by two studs (6) with threaded or non-threaded blocker (7), integral with one end to the other and on the other, they have the repeated blocker or nut (7 ) that has the particularity of being fixed at the other end, blocking the columns (2), without highlighting on the surface of these (2), achieving the impossibility of getting out or loosening of its alveoli fixed in the support columns (2) . These limit its opening by the extension or length of the seat (1) that is flexible to facilitate folding. 2. Folding sports chair, according to claim 1, characterized by having at the bottom of the support columns (2) and in the deployed position, an optimal support of the leg (8) to the ground by means of a biased surface of the end of the support tube (2) that rests on the ground (8). Likewise, this system can be replaced or complemented by an anti-sinking element consisting of a disc (9) with a diameter greater than the support tube (2). 3. Folding sports chair, according to previous claims, characterized by having a system with grooves (4), to shorten or lengthen the conveyor belt (3) and prevent its dragging along the ground. The operation of this system is carried out in a semi-automatic way, that is, when the user is pulling on the conveyor belt (3) and once this action is finished, its position will be fixed. This is achieved by anchoring the conveyor belt (3) at one end of the support tube (2) and the other end (6) is inserted into a body with grooves (4), passing through several of them (4) , crushing when exerting pressure on the conveyor belt (3). Similarly, the axis between the two slots can be mobile or fixed, achieving the same effect. To leave the system in position to shorten or lengthen the conveyor belt (3), just press it (3), sliding it over the grooves
(4). In order to avoid unwanted opening of the sports chair in its folded position, has a ribbon or strap (5) with its corresponding closure to fasten it, which anchored to one of the support columns (2), hug the other (2).
