TW201300146A - Fully flexible device of the chest-expander type made up of at least two gripping elements, preferably 4, 6 or 8 elements - Google Patents

Abstract

Fully flexible device (1) of the chest-expander type comprising at least two gripping elements (2, 3) each made up of a material of the elastic strip type (either a single strip folded back on itself along its length L, or two superimposed strips of length L). The said at least two gripping elements (2, 3) are connected to one another by an element of transverse linkage (4) produced by ''weaving'' the fabric fibres and latex fibres directly together, and may optionally be terminated at their ends by another element of linkage by weaving.

Description

A chest-type fully elastic device consisting of at least two gripping units, preferably four, six or eight units

The present invention relates to technical aspects of devices for gymnastics, physical therapy, and muscle strengthening. More particularly, it relates to the field of chest expanders, that is to say devices that allow muscles to be tightened, in particular devices that include elastic strips.

Conventional devices include a strip of latex or an elastic strip made of a strap, or a tubular member having a handle at the ends.

In particular, the applicant has proposed French Patent No. FR 91/1111174.

This patent relates to an elastic strip type device made of fabric-covered latex fibers and composed of eight units. These latex fibers are naturally used to promote the elasticity of the fabric and thus contribute to the elasticity of the strip.

To produce this device, the elastic strip is built in such a way that it folds into two layers on itself. In the second phase, transverse sutures are applied, all of which are regularly spaced along the strip. In fact, the winner is the breast-throwing device which contains a number, preferably eight gripping spaces.

This has the goal of being able to grasp the device at different points on the strip, and thus the target of varying impedance strength, and making it possible to perform many applications using different parts of the body.

For eight units, it is therefore necessary to have seven transverse sutures.

These sutures are produced by sewing threads in a generally known manner, The sewing thread is stitched transversely over the entire width of the strip.

One of the major drawbacks of this suture is that the stitched fabric (and therefore the elastic latex) damages both the fabric and the latex, thereby attenuating the fact of the device.

The Applicant has actually observed that the wear and degradation of the strip becomes apparent with repetition, intense movement, and the like.

This in particular leads to the fact that the elasticity of the strip (the first and original function) is no longer the same as the original elasticity.

In some cases, it has even been observed that the strip is being subjected to local tearing, rendering the device unusable.

Despite research for the purpose of improving its original device, the applicant has not yet successfully found a solution to these shortcomings.

The technical problem caused: therefore there is a real need to build the chest-type device with a latex-containing fabric that makes it possible to ensure maximum strength while ensuring durability and stable elasticity over time. There are no local tears, even during repetition and intense exercise.

The invention thus relates to a fully elastic device of a thoracotomy consisting of at least two gripping units, preferably four, six or eight units. The only restriction in this number is the number of connections to the human body.

A preferred mode of embodiment of the elastic means is as follows: An elastic strip is formed which is composed of an elastic unit, preferably a strip or a thin line of latex, and is covered with a fabric.

Those skilled in the art are fully aware of the fact that the braid is arranged in the direction of the warp yarns and the fine lines perpendicular to the warp yarns arranged in the direction of the weft yarn are interwoven in the same plane.

It will naturally be possible to use other elastic materials that have been obtained by those skilled in the art. Latex is preferred herein, and in the range of latex, the latex provides such optimum assurance in terms of elasticity and strength.

The two bands are overlapped and their lengths are overlapped (or one band and its length are reversed on itself), and at least one mechanism of the lateral joints is established over the two overlapping strips (and optionally Each end portion, thereby defining at least two gripping mechanisms, the gripping mechanisms forming a "ring" formed between the lateral joints or the joints, preferably in a number of four or six Still more preferably eight.

Here, by means of "mechanism of the transverse joints", it is intended that the strips (or strips that are folded back on themselves, likewise forming two strips) are joined together at least one point in a lateral manner. The fact that the at least two gripping mechanisms are defined on either side of the mechanism of the lateral joint.

The mechanism of the transverse joint according to the invention is a "braiding method" in which the latex fibers and the woven fibers are directly woven together at a point predefined by the user (very general, used in The same point of the "rings".

The dimensions of the "rings" will be designed and positioned such that the user can insert their hands and/or their feet into the loops.

It would be entirely possible to imagine other modes for the specific embodiment of the linking mechanism, which is different from the horizontal mode, such as in the form of a bit pattern, A pattern that is slanted, spanning half of this width, and so on. Only those skilled in the art will judge that one form or another form of association is used according to his wishes.

However, for obvious reasons related to strength and handling, the Applicant strongly advocates the use of the full, lateral type of joining mechanism, that is, the weaving method of the entire width.

The "width" (1) is defined as a direction perpendicular to the direction of the strip that will constitute the length (L).

In a completely surprising way, it has been observed that the weaving process carried out never causes damage to the fibers of the fabric or to the latex fibers, since the inelastic threads are woven together to form the grips. Unit, and in this case does not damage the thin strip of latex.

This guarantees maximum strength and optimum elasticity even after intense and repeated stresses.

The applicant has performed a series of tests on the grip unit (with the aid of a pneumatic jack whose stroke is adjusted to apply a traction of at least 200 kg in the direction of the length). It has been observed that once the first stress is applied (the suture has been "decomposed"), the prior art elastic strip becomes completely unusable, whereas it is subjected to 15 cycles of stress to apply the same stress applied Damage to the unit.

The strength of the device is thus fully demonstrated.

Furthermore, the Applicant has observed that because the joining unit is a woven fabric, and because the latex fibers and woven fibers are not "locked" to the suture by the suture itself, a significant increase in elasticity is Achieved. This first test made it possible to record that the increase was significant and greater than 10 percent.

As can be seen in Figure 1, the elastic strip (1) according to the invention consists of at least two gripping units (2, 3).

As can be seen from Figure 4, each of the gripping units (2 or 3) includes an upper portion (5) and a lower portion (6) forming a "ring".

The two gripping units (2, 3) are connected by means of a unit of transverse joints (4) produced by weaving the strips. It will be observed that the two gripping units can have exactly the same or different lengths (L/2).

As can be seen in Figure 2, when the gripping units (2, 3) are stretched to this maximum, the lateral joints (4) of the unit will tend to suffer a slight increase in width (with 1 for comparison). This is due to the fact that the joining unit is a braid and not a suture (the suture naturally cannot be deformed).

In addition to the unit of the transverse joint (4), it is also possible to weave a grip unit formed over its length (L/2) in order to create a "pocket" type (P) unit, that is to say by being located The two units of the lateral joints on the left and right sides define their extent, and then the upper (5) and lower portions of the grip unit are at their upper edges (7a and 7b) or lower edges (8a and 8b) ( 6) Weave together (T).

In the case of this illustration, it is clear that the gripping unit (2'), (3'), etc. will be found on the strip. It is also possible to provide one or more gripping units between the pockets P2 and P3.

It is also possible to provide a single pocket (P) between the gripping units (2', 3').

It can also be such that the pocket or pockets (P) are located at the end of the elastic strip. unit.

The elastic strip includes two, four, six or eight gripping units, a portion of which can be selectively separated by a pocket (P).

In this way, the user can place a heavy unit in the pocket or pockets (tables, legs, etc.) to hold the elastic strip in place while the user uses one or more Other gripping units make this movement.

According to a preferred mode of the specific embodiment, the elastic strip comprises eight gripping units, each gripping unit having a length of 10 cm and a width of 5 cm.

Naturally, other sizes can be selected.

The present invention also encompasses all of the modes and all such applications of the present invention, which will be readily understood by those skilled in the art upon reading this application and the knowledge of the disclosure.
