The present invention relates to a cloth assembly for making a protective pad for sports and, more particularly, to a cloth assembly including an air-permeable cloth and a knitted cloth to provide an elastic, air-permeable, stretchable, and easy-to-use cloth.
Conventional protective pads for sports are generally made from a cloth assembly comprised of a substrate of neoprene or ethylene vinyl acetate (EVA) and a knitted cloth bonded to the substrate. Such a cloth assembly is stretchable and can be wrapped around a portion of a wearer such that the protective pad can deform responsive to movement of the portion of the wearer, reducing discomfort resulting from sports. However, the protective pad made of such a cloth assembly is not permeable to air.
A sandwiched type cloth assembly has been proposed to provide air permeability, softness, and stretchability. Specifically, the sandwiched type cloth assembly includes two parallel, spaced knitted cloths and a plurality of supporting fibers extending between the knitted cloths, with the supporting fibers providing elasticity. Although such a sandwiched type cloth assembly provides air permeability and softness and can be used to make protective pads for sports, the cloth assembly does not include a loop tape including loops that allow easy and releasably engagement with hooks of a hook tape. Namely, an additional loop tape is required. Furthermore, if it is intended to directly produce loops on a surface of the cloth assembly, the structure of the sandwiched type cloth assembly will be damaged. Thus, the sandwiched type cloth assembly is not suitable for direct manufacture of protective pads for sports.
In a solution to the above disadvantage, a loop tape is provided on the whole surface of the sandwiched type cloth assembly so that the sandwiched type cloth assembly can be used to make a protective pad for sports and can be wrapped around a portion of a wearer. A hook tape is provided to engage with the loops of the loop tape when the protective pad is wrapped around the user, providing desired positioning effect. However, the cloth assembly including the loop tape is not stretchable such that the cloth assembly can not be intimate contact with the portion of the wearer. Thus, the protective pad can not stretch responsive to movement of the portion of the wearer, causing discomfort to the user during sporting.
Thus, a need exists for a novel cloth assembly that can provide elasticity, air permeability, stretchability, and easy engagement.
The present invention solves this need and other problems in the field of the material for making protective pads for sports by providing a cloth assembly including a first knitted cloth having an outer face and an inner face opposite to the outer face. A second knitted cloth includes an outer surface and an inner surface opposite to the outer surface. A plurality of supporting fibers extends between the inner face of the first knitted cloth and the inner surface of the second knitted cloth. Each of the plurality of supporting fibers includes a first end fixed to the inner face of the first knitted cloth and a second end fixed to the inner surface of the second knitted cloth. The plurality of supporting fibers supports the first and second knitted cloths. The first and second knitted cloths and the plurality of supporting fibers form an air-permeable cloth. A knitted cloth includes a first side and a second side opposite to the first side. The first side includes a plurality of loops formed by a plurality of fibers of the knitted cloth. The second side of the knitted cloth is bonded to the outer face of the first knitted cloth. A hook tape includes a first face and a second face opposite to the first face. The first face of the hook tape includes a plurality of hooks. The hook tape is fixed to the first side of the knitted cloth or the outer surface of the second knitted cloth.
When the hook tape is fixed to the first side of the knitted cloth, the first face of the hook tape faces the first side of the knitted cloth, a portion of the hook tape overlaps and is fixed to an end of the knitted cloth, and a remaining portion of the hook tape extends beyond the end of the knitted cloth.
On the other hand, when the hook tape is fixed to the outer surface of the second knitted face, the second face of the hook tape faces the outer surface of the second knitted face, the plurality of hooks of the hook tape is exposed and faces away from the outer surface of the second knitted cloth.
The air-permeable cloth and the knitted cloth fixed thereto are adapted to be wrapped around a portion of a wearer. When the air-permeable cloth and the knitted cloth are wrapped around the portion of the wearer, the plurality of hooks of the hook tape is releasably engaged with the loops of the knitted cloth.
In a form shown, the remaining portion of the hook tape has a length about ½ to 4/3 of an overall length of the hook tape.
The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.
The illustrative embodiments may best be described by reference to the accompanying drawings where:
All figures are drawn for ease of explanation of the basic teachings only; the extensions of the figures with respect to number, position, relationship, and dimensions of the parts to form the illustrative embodiments will be explained or will be within the skill of the art after the following teachings have been read and understood. Further, the exact dimensions and dimensional proportions to conform to specific force, weight, strength, and similar requirements will likewise be within the skill of the art after the following teachings have been read and understood.
Where used in the various figures of the drawings, the same numerals designate the same or similar parts. Furthermore, when the terms “first”, “second”, “inner”, “outer”, “side”, “end”, “portion”, “section”, “length”, and similar terms are used herein, it should be understood that these terms have reference only to the structure shown in the drawings as it would appear to a person viewing the drawings and are utilized only to facilitate describing the illustrative embodiments.
A cloth assembly according to the present invention is shown in the drawings and generally designated 10. Cloth assembly 10 includes an air-permeable cloth 12. In the form shown, air-permeable cloth 12 includes a first knitted cloth 20 having an outer face 22 and an inner face 24 opposite to the outer face 22. Air-permeable cloth 12 further includes a second knitted cloth 30 having an outer surface 32 and an inner surface 34 opposite to outer surface 32. Air-permeable cloth 12 further includes a plurality of supporting fibers 40 extending between inner face 24 of first knitted cloth 20 and inner surface 34 of second knitted cloth 30. Each supporting fiber 40 includes a first end 42 fixed to inner face 24 and spaced from outer face 22 of first knitted cloth 20. Each supporting fiber 40 further includes a second end 44 fixed to inner surface 34 and spaced from outer surface 32 of second knitted cloth 30. Thus, a sandwich structure having three layers is provide, with supporting fibers 40 supporting first and second knitted cloths 20 and 30 to provide elasticity, and with gaps between supporting fibers 40 providing air-permeable effect.
Cloth assembly 10 further includes a knitted cloth 50 having a first side 52 and a second side 54 opposite to first side 52. First side 52 includes a plurality of loops 56 formed by a plurality of fibers of knitted cloth 50. Specifically, loops 56 can be formed by a napping procedure, such as by using a napping wheel of a napping machine, by using a nap-raising brush of a carder, by using a teasing needle, or by other knitting processing. Thus, loops 56 protrude out of first side 52 of knitted cloth 50 and serve as loops of a loop tape for releasable engagement with a hook tape. Second side 54 of knitted cloth 50 is fixed to the outer face 22 of first knitted cloth 20 by such as using glue 58. Thus, loops 56 are provided on an outer surface of air-permeable cloth 12 for releasable engagement with a hook tape.
Cloth assembly 10 further includes a hook tape 60 fixed to first side 52 of knitted cloth 50 or outer surface 32 of second knitted cloth 30 according to the type of the protective pads to be made. Hook tape 60 includes a first face 62 and a second face 64 opposite to first face 62. First face 62 of hook tape 60 includes a plurality of hooks 66.

Thus, by providing knitted cloth 50 fixed to air-permeable cloth 12 and by providing hook tape 60 fixed to first side 52 of knitted cloth 50 or outer surface 32 of second knitted cloth 30, cloth assembly 10 can be used to make a protective pad for sports. Since loops 56 are provided on first side 52 of knitted cloth 50, a surface of cloth assembly 10 thus formed can serve as a loop tape having loops. The protective pad made of cloth assembly 10 can be wrapped around a portion of a wearer to be protected, with hooks 66 of hook tape 60 engaged with loops 56 of knitted cloth 50. Thus, the protective pad can be in intimate contact with the skin of the portion of the wearer and can deform responsive to movement of the portion of the wearer, providing use comfort.
Now that the basic teachings of the present invention have been explained, many extensions and variations will be obvious to one having ordinary skill in the art. For example, second side 54 of knitted cloth 50 can be bonded to outer surface 32 of second knitted cloth 30 of air-permeable cloth 12, and hook tape 60 can be fixed to outer face 22 of first knitted cloth 20. Furthermore, cloth assembly 10 can be used to make a wrist protector for protecting a wrist of a wearer. The wrist protector can include an opening similar to opening 70 of the example shown in
