Description
- The present invention relates generally to surface type fasteners known as hook-and-loop fasteners, and more particularly to a fabric fastener tape carrying on its one surface a number of improved hook-shaped material engaging means.
- According to a known method (FR-A-11887145), a hooked fabric fastener tape of the type described has on one of opposite surfaces of a foundation structure a number of hook-shaped material engaging elements and stems which have been produced in pair by cutting loops on the respective one leg sections thereof, the loops being made of synthetic resin monofilaments woven into the foundation structure and raising from said one surface thereof. The prior art hooked fabric fastener tape is disadvantageous in that the stems have their respective free ends disposed adjacent to and substantially confronting relation to the free ends of the corresponding hook-shaped materia! engaging elements. Such stems have no function to hook the cooperating loops on a mating looped fabric fastener tape, or rather hinder the loops from being introduced into hooking engagement with the hook-shaped material engaging elements as the two fasteners tapes are pressed into face-to-face contact together. As a result, the possibility of hooking between hooks and loops, i.e., the firmness of engagement of a hook-and-loop fastener decreases considerably.
- According to the invention, there is provided a hooked fabric fastener tape including a foundation structure and a number of material engaging means projecting from one surface of the foundation structure and each made by cutting one loop of synthetic resin thread woven into the foundation structure, each of the loops including a pair of leg sections and a head section interconnecting the leg sections. Each of material engaging means comprises a pair of hooks, one of said hooks being larger in height than the other hook.
- The present invention seeks to provide a hooked fabric fastener tape for hook-and-loop fasteners which can adhere to or engage with a mating looped fabric fastener tape with an increased degree of firmness.
- The invention also seeks to provide a hooked fabric fastener tape having hook-shaped material engaging means which can hook cooperating loops of a mating looped fabric fastener tape reliably without causing mis- engagement therewith.
- The invention further seeks to provide a hooked fabric fastener tape having improved hooks reliably engageable with any cooperating loops fanned apart on a mating looped fabric fastener tape.
- The above and other objects, advantages and features of the present invention will become apparent from the following purely illustrative and not limitative description of preferred embodiments taken in conjunction with the accompanying drawings, in which:
- Figure 1 is a fragmentary diagrammatic side elevational view of a hooked fabric fastener tape according to the present invention; and
- Figure 2 is a view similar to Figure 1, showing a modified hooked fabric fastener tape of the present invention which is brought into hooking engagement with a mating looped fabric fastener tape.
- Referring now to the drawing, and more particularly to Figure 1, there is shown a hooked fabric fastener tape 10 constructed in accordance with the present invention. The hooked fabric fastener tape 10 includes a foundation structure 11 and a number of material engaging means 12 projecting from one surface of the foundation structure 11. The foundation structure 11 is constituted by weaving together a weft thread and a plurality of warp threads in a well-known manner. Each of the material engaging means 12 comprises a pair of
hooks hooks - One of the
hooks 13 of each material engaging means 12 is larger in height than theother hook 14. The one orlarge hook 13 is formed jointly with one of the leg sections, the head section and a portion of the other leg section which has been cut whereas the other orsmall hook 14 is formed with the remainder of the other or cut leg section, the free end of the remainder leg being curved to formed alocking end portion 15. Thelocking end portion 15 of thesmall hook 14 curved toward thelarge hook 13 and directed to one of the surfaces of the foundation structure 11, thereby providing between thelocking end portion 15 and thefree end 16 of the large hook 13 alarge opening 17 for easy reception of cooperatingloops fabric fastener tape 19 shown by phantom lines in Figure 2. Although suchsmall hooks 14 as illustrated are very advantageous to give the hooked fabric fastener a maximum number of hooks per unit area, they may have their respective locking end portions curved into any directions with respect to the correspondinglarge hooks 13. - Figure 2 shows a modified hooked
fabric fastener tape 20 havingmaterial engaging means 21 each comprising a pair ofhooks foundation structure 24, one of thehooks 22 being larger in height than theother hook 23. Thesmall hooks 23 are the same as thesmall hooks 14 shown in Figure 1, but thelarge hooks 22 are different from the aforesaidlarge hooks 13 in that their respective free ends of lockingportions 25 are curled so as to hold more securely the cooperatingloops fabric fastener tapes locking end portion 25 and alocking end portion 26 ofsmall hook 23 is anopening 27 larger than the opening 17 shown in Figure 1, theopening 27 allowing thecooperating loops fabric fastener tape 19 to enter more smoothly into hooking engagement with thehooks fastener tapes - As best shown in Figure 2, the hooked fabric fastener tape 20 (10) of the invention can adhere to or engage with the mating looped
fabric fastener 19 with an increased degree of firmness through the hooking engagement between, on one hand, the large hooks 13 (22) andrecumbent ones 18a of fanned-apart loops upstanding loops 18b.
