Definitions

  • the present invention relates to an elastic strap that is used to train a user's strength by manipulating it with their hands and/or feet; wherein the elastic strap comprises a single piece that is obtained by weaving threads and rubber bands in a longitudinal succession of corrugated sections and smooth sections; and wherein the elastic strap includes at its ends handles created from two corrugated sections with a closed loop configuration. If there is a break in a corrugated section, this structure of the strap of the invention allows, on the one hand, for the possible continued use of the strap and, on the other hand, prevents it from causing injury to the user.
  • the technical field that encompasses the present invention is that belonging to apparatuses for practising sports and gymnastics, and more specifically individual apparatuses for exercising a user's strength.
  • These elastic straps comprise a non-woven construction made up of several pieces, such as a rubber core and a wrap-around structure with metallic elements that have a wrap-around configuration running parallel around and along the entire length of the rubber core and that have handles with metallic or plastic assembly elements at the ends.
  • This described elastic strap is a construction (without alternating corrugated and smooth sections) with an outer fabric (wrap-around structure) lacking elasticity, or in the best-case scenario with less elasticity than the rubber core, such that the breakage of said rubber core or disassembly of the assembly renders the elastic strap useless.
  • the strap is made up of an elastic rubber band with handles or without handles (closed loop), which may cause harm to the user in the event of breakage.
  • corrugated straps are known but they do not have the same function as the elastic strap of the invention.
  • the function of the corrugation is to have more centimetres of strap to facilitate its handling without the strap hanging.
  • the invention proposes an elastic strap that comprises along its entire length a woven tubular structure, made up of a ligature, a main resistant elastic and an additional elastic.
  • the ligature, the main elastic and the additional elastic are three internal elements, each made up of several branches running substantially along the entire length of an inner space delimited by the tubular structure, with the particularity that these three internal elements are linked and joined to said tubular structure.
  • the elastic strap comprises a succession of corrugated sections and smooth sections, both sections affecting all the elements of the elastic strap; and wherein 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 fastened and guided in the smooth sections; while in the corrugated sections, the branches of the main elastic are guided but not fastened with freedom of linear mobility along the corrugated sections; wherein the branches of the main elastic in said corrugated sections have a greater lengthening or range of elongation and less resistance than in the smooth sections due to the construction.
  • the main elastic (rubber) is always protected from reaching the limit or maximum point of stress.
  • the branches of the ligature which are guided but not fastened, run along the inner space in the corrugated sections, while in the smooth sections, the branches of said ligature are intertwined and fastened on the tubular structure; wherein said intertwining and fastening branches 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 fastened and guided along the inner space of the tubular structure.
  • the tubular structure in its corrugated section comprises a wave-shaped configuration made up of two opposite areas that have external vertices and internal vertices; wherein the branches of the additional elastic are linked to the internal vertices of the two opposite areas of the wave-shaped configuration.
  • the several branches of the main elastic element run in parallel along longitudinal channels of the inner space that are delimited between portions of the tubular structure, the branches of the ligature and the branches of the additional elastic.
  • the several longitudinal channels are delimited in the corrugated sections between portions of the tubular structure, the branches of the additional elastic joining opposite areas of the tubular structure and the branches of the ligature running 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 joining opposite areas of the tubular structure and the branches of the additional elastic running parallel to the branches of the main elastic.
  • the strap of the invention comprises a woven construction made of a single piece, which makes it more durable, it cannot be disassembled, and at the same time its breakage does not occur suddenly (as occurs with other elastic straps in the state of the art), which prevents injury to the user and maintains its usability.
  • conventional elastic straps comprise a single main elastic (rubber) made up of a single branch that ends up breaking or disassembling over time with the use of the strap, making the strap unusable, since the rubber is split into two parts.
  • the main elastic comprised of several branches can break into one or more of these branches, such that due to the fact that the strap is woven in alternating smooth and corrugated sections that make up a single piece, said section of the elastic strap will only be partially affected (depending on the number of branches that break).
  • This construction of the elastic strap allows that same branch to continue functioning in the other sections of the elastic strap, exerting the same tensile strength. As a result, the effect of breaking a branch of the main elastic is limited to that single section.
  • the elastic strap comprises an alternating succession of corrugated sections 1 and smooth sections 2, which, if there is a break in a corrugated section 1, it allows, on the one hand, for the possible continued use of the strap and, on the other hand, prevents it from causing injury to the user.
  • the elastic strap of the invention shown in figures 1 to 6 , includes at its opposite ends closed-loop handles 3 that are made up of the material of the strap itself 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 that 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 strap comprises a tubular structure 4 that is flexible, elastic and integrates a ligature 5, a main resistant elastic 6 and an additional elastic 7 that has the function of configuring the corrugated sections 1 due to the tension of said additional elastic 7; wherein all these elements run along the entire length of the strap.
  • the tubular structure 4 is made up of the combination of a warp 4a and 4b, a weft 4c with the integration of the ligature 5, the main resistant elastic 6 and the additional elastic 7.
  • the ligature 5, the main elastic 6 and the additional elastic 7 are three internal elements running substantially along the entire length of an inner space 8 delimited by the tubular structure 4, with the particularity that these internal elements are joined and linked in different ways to said tubular structure 4, as will be described later. Furthermore, these three internal elements 5, 6 and 7 each comprise several branches.
  • the main elastic (rubber) 6 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 undergoes any degradation, it occurs by sections in some of its several branches and not in all of them.
  • the main elastic 6 in said corrugated sections 1 has a greater lengthening or range of elongation than in the smooth sections 2.
  • the several branches of the elastic element 6 run in parallel along longitudinal channels of the inner space 8 that are delimited between portions of the tubular structure 4 (made up of the warp 4a and 4b and the weft 4c), the branches of the ligature 5 and the branches of the additional elastic 7.
  • the ligature 5 comprises several branches running freely without fastening along the inner 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.
  • 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 band 7 runs guided and fastened, but not intertwined, along the inner space 8 of the tubular structure 4.
  • the several longitudinal channels in which the several branches of the main elastic 6 are located along the entire length of the strap are first delimited in the corrugated sections 1 ( figure 5 ) between portions of the tubular structure 4, the branches of the additional elastic 7 joining opposite areas of the tubular structure 4 and the branches of the ligature 5 running parallel to the branches of the main elastic 6.
  • the longitudinal channels are delimited between portions of the tubular structure 4, the branches of the ligature 5 joining opposite areas of the tubular structure 4 and the branches of the additional elastic 7 running parallel to the branches of the main elastic 6.
  • the additional elastic 7 also made up of 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; wherein said additional elastic 7 is intertwined in the internal vertices 1b that, like the external vertices, make up the tubular structure 4.
  • the branches of the main elastic 6, additional elastic 7 and ligature 5 run along the inner space 8 of the tubular structure 4 in repeated cross-sectional sets; 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 link the opposite areas of the tubular structure 4 through the internal vertices 1b of the wave formation.
  • each smooth section 2 ( figure 6 )
  • the branches of the main elastic 6 and the branches of the additional elastic 7 have a longitudinal path along the strap, 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 strap shown in figure 7 shows a closed-loop annular configuration, which is obtained from a linear strap, the smooth end sections 2 of which have been integrally joined together by means of a second zigzag seam 9.
  • the degree of lengthening or elongation of the components of the strap 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 lengthening or elongation of the strap.
  • tubular structure 4 is the safety element against possible breakage, so that what breaks or can break due to wear are the branches of the main elastic 6.
