DESCRIPTION

ELASTIC TAPE

Object of the invention

The present invention refers to an elastic band that is used to train a user's strength by manipulating it with their hands and/or feet; where the elastic band comprises a single piece that is obtained by weaving threads and rubbers in a longitudinal achievement of corrugated sections and smooth sections; and where the elastic band includes handles at its ends created from two corrugated sections with a closed loop configuration. This structure of the tape of the invention allows that if there is a break within a corrugated section, on the one hand it is possible to continue using the tape and on the other hand it prevents it from causing injury to the user.

Technical sector

The field of technique in which the present invention is framed is that belonging to apparatus for sports and gymnastics, and more specifically to individual apparatus for exercising a user's strength.

Technical problem to be solved and background of the invention

At present, various devices and apparatus for gymnastics and sports are known, among which it is worth highlighting those devices for individual use, such as elastic bands; where a user can train the strength of their extremities and other parts of the body by manipulating said elastic band with their hands and/or feet.

These elastic bands comprise a non-woven construction made up of several pieces, such as a rubber core and an enveloping structure with metallic elements that have an enveloping configuration that runs in parallel around and along the entire length of the rubber core and at the ends have handles. with metallic or plastic assembly elements.

This described elastic tape is a construction (without alternating corrugated and smooth sections) with an outer fabric (enveloping structure) lacking in elasticity, or at best with less elasticity than the rubber core, so that the breakage of said rubber core or disassembly of the assembly renders the elastic band useless.

These conventional straps have a greater wear than the strap of the invention and this causes sudden breakage or disassembly that could cause injury to the user.

There are also tapes on the market that do not have an enveloping structure. In this case, the strap is made up of an elastic band with or without handles (closed loop), which in the event of breakage can cause harm to the user.

In addition, in the sports sector there are tapes called elastic bands that have several rubber strands, but always in the smooth format, never in the corrugated format or a combination of both.

Corrugated tapes are known in the security sector, but not with the same function as the elastic tape of the invention. In this case, the function of the corrugation is to have more centimeters of tape to facilitate its handling without the tape hanging.

Description of the invention

In order to achieve the objectives and avoid the drawbacks in the previous sections, the invention proposes an elastic band that comprises, along its entire length, a woven tubular structure, formed by a ligature, a resistant main elastic and an additional elastic. .

The ligature, the main elastic and the additional elastic are three internal elements each formed by several branches that run substantially the entire length of an interior space delimited by the tubular structure, with the particularity that these three internal elements are linked and attached to said tubular structure.

On the other hand, the elastic band comprises a succession of corrugated sections and smooth sections that affect all the elements of the elastic band; where the additional elastic has the function of configuring the corrugated sections due to its permanent elastic tension in said sections.

The branches of the main elastic are supported and guided in the smooth sections; while in the corrugated sections, the branches of the main elastic are guided but not subjects with freedom of linear mobility along the corrugated sections; where the branches of the main elastic in said corrugated sections have a greater elongation or elongation range and with less resistance than in the smooth sections due to the construction.

It should be noted that thanks to the woven construction of the tape of the invention, the main elastic (rubber) is always protected from reaching the limit or maximum point of stress.

The branches of the ligature run through the interior space in the corrugated sections, guided but not attached, while in the smooth sections, the branches of said ligature are intertwined and attached to the tubular structure; where said interlocking and fastening anchor opposite areas of the tubular structure.

The branches of the additional elastic are intertwined in opposite areas of the tubular structure in the corrugated sections, while in the smooth sections, said additional elastic runs supported and guided by the interior space of the tubular structure.

The tubular structure in its corrugated section comprises a wave-shaped configuration formed by two opposite zones that have external vertices and internal vertices; where the branches of the additional elastic are linked to the internal vertices of the two opposite zones of the wave-shaped configuration.

The various branches of the main elastic element run in parallel along longitudinal channels of the interior space that are delimited between parts of the tubular structure, the branches of the ligature and the branches of the additional elastic.

The various longitudinal channels are delimited by the corrugated sections between portions of the tubular structure, the branches of the additional elastic that join opposite areas of the tubular structure, and the branches of the ligature that run parallel to the branches of the main elastic; while in the smooth sections the longitudinal channels are delimited between portions of the tubular structure, the branches of the ligature that join opposite areas of the tubular structure and the branches of the additional elastic that run parallel to the branches of the main elastic.

Thus, the tape of the invention comprises a one-piece woven construction, which which makes it more durable, it cannot be disassembled, and at the same time it does not break suddenly (as occurs with other elastic bands of the state of the art), which prevents injuries to the user and maintains its usability.

It should be noted that in conventional elastic bands they comprise a single main elastic band (rubber) made up of a single branch that over time, with the use of the band, ends up breaking or disassembling, making the band unusable, since the broken rubber remains. in two parts.

On the other hand, in the elastic band of the invention, the main elastic made up of several branches can break in one or more of these, so that because the band is woven in alternating smooth and corrugated sections, forming a single piece, that section of the elastic band will only be partially affected (depending on the number of branches that break).

This construction of the elastic band allows that same branch to continue working in the other stretches of the elastic band, exerting the same resistance to traction. Consequently, the effect of breaking a branch of the main elastic is limited to that single section.

Below, to facilitate a better understanding of this specification and forming an integral part of it, a series of figures are attached in which, with an illustrative and non-limiting nature, the object of the invention has been represented.

Description of an exemplary embodiment of the invention

Considering the numbering adopted in the figures, the elastic tape comprises an alternating succession of corrugated sections 1 and smooth sections 2, which allows that if there is a break within a corrugated section 1, on the one hand it is possible to continue using the tape and on the other hand, it prevents the possibility of causing injury to the user.

The elastic band of the invention, shown in figures 1 to 6, includes at its opposite ends closed-loop handles 3 that are formed by the material of the band that is sewn by means of a first zigzag seam 9' that joins two smooth sections 2; Specifically, for each handle 3, two smooth sections 2 are sewn, separated by a corrugated section 1, which finally performs the function of the handle 3 itself.

The corrugated sections 1 have a higher degree of elasticity and flexibility than the smooth sections 2.

The elastic band comprises a tubular structure 4, flexible, elastic and that integrates a ligature 5, a resistant main elastic 6 and an additional elastic 7 that has the function of configuring the corrugated sections 1 thanks to the tension of said additional elastic 7; where all these elements run along the entire length of the tape.

The tubular structure 4 is formed by the combination of a warp 4a and 4b, a weft 4c with the integration of the ligature 5, the main elastic 6 resistant and the additional elastic 7.

The ligature 5, the main elastic 6 and the additional elastic 7 are three internal elements that run substantially the entire length of an interior space 8 delimited by the tubular structure 4, with the particularity that these internal elements are joined and linked in different ways. shapes said tubular structure 4, as will be described later. In addition, these three internal elements 5, 6 and 7 each comprise several branches.

The main elastic 6 (rubber) comprises several branches that are fastened and guided in the smooth sections 2 (figure 6) preventing the complete breakage of said main elastic 6, with the advantage that when it suffers any degradation, it is produced by sections in some of its several branches and not in all of them.

On the other hand, in the corrugated sections 1 (figure 5), the various branches of the main elastic 6 are guided but not subject, having freedom of linear mobility along the corrugated sections 1, these suffering wear with the use of the tape. gradual. Therefore, the main elastic 6 in said corrugated sections 1 has a greater elongation or range of elongation than in the smooth sections 2.

Thus, as shown more clearly in figures 5 and 6, the various branches of the elastic element 6 run in parallel along some longitudinal channels of the interior space 8 that are delimited between parts of the tubular structure 4 (formed by the warp 4a and 4b, and weft 4c), the strands of the slur 5 and the strands of the additional elastic 7.

As shown more clearly in figures 4, 5 and 6, the ligature 5 comprises several branches that run freely without restraint through the interior space 8 of the corrugated sections 1 (figure 5), while in the smooth sections 2 (figure 6 ), said ligature 5 is intertwined and fastened in the tubular structure 4 and more specifically in opposite areas of the tubular structure 4. In this way, said opposite areas are joined together by said ligature 5

In turn, the additional elastic 7 is intertwined and fastened in opposite areas of the tubular structure 4 in the corrugated sections 1 (figure 5), while in the smooth sections (figure 6), said additional elastic 7 runs guided and fastened, but not interlocked, by the interior space 8 of the tubular structure 4.

The several longitudinal channels in which the various branches of the main elastic 6 are located along the entire length of the belt, are first delimited in the corrugated sections 1 (figure 5) between portions of the tubular structure 4, the branches of the additional elastic 7 that join opposite areas of the tubular structure 4 and the branches of the ligature 5 that run parallel to the branches of the main elastic 6.

Secondly, in the smooth sections 2 (figure 6) the longitudinal channels are delimited between portions of the tubular structure 4, the branches of the ligature 5 that join opposite areas of the tubular structure 4 and the branches of the additional elastic 7 that run parallel to the branches of the main elastic 6.

The additional elastic 7, also formed by several branches, is responsible for maintaining the discontinuity of the tubular structure 4 in the corrugated sections 1, configuring a wave formation (figure 4) that has external vertices 1a and internal vertices 1b; where said additional elastic 7 is interlaced in the internal vertices 1b that are part, like the external vertices, of the tubular structure 4.

As shown in figures 5 and 6, the branches of the main elastic 6, additional elastic 7 and ligature 5, run through the interior space 8 of the tubular structure 4 in repeated transversal series; so that considering the cross section of each corrugated section 1 (figure 5) the branches of the main elastic 6 and the branches of the ligature 5 have a longitudinal path following the wave formation in parallel, while the branches of the additional elastic 7 intertwine and they link the opposite zones of the tubular structure 4 through the internal vertices 1b of the wave formation.

In line with what was said in the preceding paragraph, in the cross section of each smooth section 2 (figure 6) the branches of the main elastic 6 and the branches of the additional elastic 7 have a longitudinal route along the strip, while the branches of the ligature 5 intertwine and link the opposite areas of the tubular structure 4 in each smooth section 2.

The elastic band shown in Figure 7 shows a closed-loop annular configuration, which is obtained from a linear band, whose smooth end sections 2 have been integrally joined together by means of a second zigzag seam 9.

The degree of elongation or elongation of the components of the tape of the invention is defined as follows: the main elastic 6 is the element that has the most elongation, then the additional elastic 7 and finally the tubular structure 4. The tubular structure 4 marks the maximum degree of elongation or elongation of the tape.

It should be noted that the tubular structure 4 is the security element against a possible rupture, so that what breaks or can break due to wear are the branches of the main elastic 6.

On the other hand, the comparison of some conventional elastic tapes with the tape of the invention in rupture tests is described below.

- A first conventional tape. In case of breakage, the rubber (main elastic element) would be covered, although the product would be disassembled.

- A second conventional strap, with a breaking limit of 53.2 kg, is released at least one of the two metal rings that is included at the ends of the strap.

- A third conventional long belt has a breaking limit of 262.9 kg.; where in this case the break would affect the cover.

- A first model of the tape of the invention with a breaking limit of 748.1 kg.; where the break occurs in the seam area of the handle or handle.

- A fourth tape model of the invention. The breaking limit is 1061.1 kg.; where the stitching is partially broken and the tape completely broken by the seam area of the handle or handle.

The following describes the comparison of some conventional elastic tapes with the tape of the invention in fatigue tests.
