letter shape is provided in a top end of this engaging post 11 , so that elastic force acting to the right and left is applied . engaging heads 13 protruded outward are formed on an outer peripheral face of the engaging post 11 . nipping portions 14 for nipping the tape 6 from up and down are formed on both sides of the base 10 so as to support the base 10 between the tapes 6 . the gap 9 is formed between the opposing edges 8 of the tapes 6 opposing each other and desired to be at least larger than the size of the engaging head 13 on the engaging post 11 provided on the base 10 . on the other hand , in the female body 3 of the snap 1 to be attached on the tapes 6 which are the supports 5 opposing each other , as shown in fig3 a flat rectangular base 16 is provided across the opposing edges 8 of the tapes 6 and as shown in fig4 a circular engaging hole 17 , with which the engaging head 13 of the male body 12 engages , is formed in the center of the base 16 . a protruded row 19 is provided on the center of a peripheral wall 18 of this engaging hole 17 such that it is protruded inward . when the engaging head 13 of the male body 2 engages with this hole 17 , it fits firmly . further , nipping portions 20 for nipping the tape 6 from up and down are formed on both sides of the base 16 so as to support the female body between the tapes 6 . the gap 9 between the opposing edges 8 of the tapes 6 opposing each other is desired to be at least larger than a diameter of the engaging hole 17 made in the base 16 . the male body 2 of the snap 1 attached on the opposing edges 8 of the tapes 6 which are the opposing supports 5 , and the female body 3 of the snap 1 attached on the opposing edges 8 of the opposing tapes 6 are used as the snap with supports acting as a pair . therefore , the male bodies 2 and the female bodies 3 of the snaps 1 are attached on the tapes 6 at the same pitch . the tape 6 as the support 5 may be formed of unwoven cloth of synthetic fiber , thermoplastic resin film or synthetic leather . as described above , the tape 6 is used for the support 5 and the predetermined gap 9 is provided between the opposing tapes 6 , such that for the male portion 2 of the snap 1 , that gap 9 is larger than the diameter of the engaging head 13 and for the female portion 3 , larger than the diameter of the engaging hole 17 . as compared to the conventional product in which an attaching hole is made in the tape and the snap is formed in this attaching hole , according to the present invention , in order to attach the snap 1 on the tape 6 , two tapes 6 are arranged in parallel with the predetermined gap 9 and the male boy 2 and the female body 3 of the snap 1 are formed integrally at the constant pitch or any other pitch . in the snap with supports according to the second embodiment shown in fig5 the tape 6 is used for the support 5 and the gap 9 is provided at a predetermined interval between two tapes 6 . then , the male bodies 2 and the female bodies 3 of the snaps 1 are attached on the opposing edges 8 of the tapes 6 alternately at a predetermined pitch . as for the configuration of the snap 1 , the male bodies 2 and female bodies 3 of the snap 1 which are the same as those of the first embodiment are attached integrally . this snap with supports is used in a single strap as a product , different from the snap with supports of the first embodiment . upon use , the support 5 may be bent such that the male body 2 and the female body 3 of the snap 1 correspond to each other or the support 5 may be cut out to an appropriate length such that the male body 2 and the female body 3 correspond to each other . in the snap with supports according to a third embodiment shown in fig6 the tape 6 used for the support 5 is modified . a bead - like enlarged edge portion 21 is formed integrally on each of the opposing edges 8 of the tapes 6 such that they oppose each other on the opposing tapes 6 . by provision of the bead - like enlarged edge portions 21 on the opposing edges 8 of the tape 6 , the nipping portions 14 of the male body 2 of the snap 1 and the nipping portions 20 of the female body 3 are fixed firmly , so that the male body 2 and the female body 3 of the snap 1 never slip out of the tape 6 . in the snap with supports according to a fourth embodiment shown in fig7 two tapes 6 as the supports 5 are disposed with a predetermined distance or a gap 9 such that they are arranged in parallel . then , a male body 2 of the snap 1 made of thermoplastic resin is attached on opposing edges 8 of the tapes 6 disposed in parallel by integral molding . two circular through holes 22 are made in the vicinity of each of the opposing edges 8 of the tape 6 and square nipping portions 14 of the male body 2 are disposed on the through holes 22 . front and rear portions of the nipping portions 14 are joined through the through holes 22 so as to attach the male body 2 of the snap 1 on the opposing edges 8 of a pair of the tapes 6 . if this type of the snap is applied for fixing of a large size snap 1 , the snap 1 can be fixed to the tapes 6 firmly . of course , this snap can be applied to a small size snap 1 and this structure may be applied to the female body 3 of the snap 1 . in the snap with supports according to a fifth embodiment shown in fig8 two tapes 6 are disposed with a gap 9 having a predetermined gap such that the tapes 6 are arranged in parallel . then , a male body 2 of the snap 1 made of thermoplastic resin is attached on opposing edges 8 of the tapes 6 by integral molding . an elongated - circle shaped through hole 22 is made in the vicinity of each of the opposing edges 8 of the tape 6 and circular nipping portions 14 of the male body 2 are disposed on the through holes 22 . front and rear portions of the nipping portions 14 are joined through the elongated - circle shaped through holes 22 so as to attach the male body 2 of the snap 1 on the opposing edges 8 of a pair of the tapes 6 . in case of the snaps 1 shown in fig7 and 8 , the large - size snap 1 may be formed while pinning the tape 6 therein at the time of injection molding in order to prevent a generation of the undulation of the edges of the tapes 6 , without providing the edges of the tape 6 with the through holes 22 . in this case , the position of the through holes shown in fig7 is the most suitable . further , the base 10 , 16 of the snap 1 may be not only square , but also circular or polygonal or elliptical . in the snap with supports of a sixth embodiment shown in fig9 and 10 , a pair of strings 7 are used as the support 5 and the gap 9 is provided between the strings 7 . the snap 1 of thermoplastic resin is attached over this gap 9 by integral molding . the string 7 is formed of woven string , knitted string or braided string of synthetic fiber having circular section , elliptical section or the like . two pieces of the strings 7 having such a shape are arranged in parallel with the constant gap 9 and the snaps 1 of thermoplastic resin , that is the female bodies 3 of the snaps 1 as shown in fig9 and 10 are formed on the strings 7 at a constant pitch by injection molding means or extrusion molding means . consequently , the string 7 is covered with and fixed by the nipping portions 20 of the snap 1 . this snap with supports formed of the strings 7 is used in the same manner as the snap with supports formed of the tapes 6 . in the snap with supports of a seventh embodiment shown in fig1 and 12 , the tapes 6 are used for the supports 5 and two tapes 6 are arranged with a predetermined distance so as to provide with the gap 9 . the male bodies 2 of the snaps 1 are attached at a predetermined pitch on the opposing edges 8 of the tapes 6 and several bridge pieces 23 of thermoplastic resin are provided across the opposing edges 8 of the tapes 6 such that they are located between the longitudinally adjacent male bodies 2 . the male bodies 2 and the bridge pieces 23 are formed by integral molding simultaneously . consequently , after the snap with supports is attached on an attaching portion of an opening / closing portion of clothes by sewing , opposing edges between the snap 1 and another snap 1 are prevented from floating from the attaching portion .
this invention intends to provide a snap with supports , the snap being formed of resin across a pair of tapes in a simple manner thereby leading to improvement of productivity and securing a solid structure and practical performance . supports such as tapes are disposed in parallel with a gap . by using this gap , male bodies or female bodies of the snaps of thermoplastic resin are formed across opposing edges of the tapes opposing each other at a predetermined pitch by injection molding means or extrusion molding means . a string may be used as the support . different from a conventional processing in which an attaching hole is made in the center of the tape and resin snap is formed therein , a boring step is not necessary . thus , this snap with tapes is created through such a simple processing .
