Definitions
- ABSTRACT A pressure-sealing type of slide fastener is provided for use on closures such as diving suits, tents and the like wherein complete fluid-tightness is required.
- the fastener has a pair of opposed stringer tapes whose adjacent longitudinal marginal edge portions are tilted upwardly toward each other and held in abutting relation substantially in the fashion of a rafter when the fastener is closed by manipulating a slider. In normal closed condition of the fastener, a free space is maintained between the marginal edge portions of the respective tapes and the fastener elements attached thereto, whereby the tapes are allowed to flex in response to changing external pressure.
- This invention relates to sliding clasp fasteners and has particular reference to a fastener of the pressure sealing type in which adjacent longitudinal marginal edges of a pair of opposed stringer tapes are hermetically sealable when the fastener is closed.
- a pressure-sealing slide fastener comprises flat stringer tapes each including an integral web portion and a marginal edge portion which extends at an angle therefrom beyond the center axis, the marginal edge portion resting on a sloping portion on each of the interlocking fastener elements in its free state and being raised slightly therefrom when the elements are interlocked.
- FIG. I is a perspective view of a pressure sealing slide fastener constructed in accordance with the invention and shown in closed disposition;
- FIG. 2 is a transverse cross-sectional view ofthe same with a slider mounted thereon:
- FIG. 3 is a transverse cross-sectional view showing one of the two fastener stringers.
- Each individual fastener element 13 has an engaging portion 13a adapted to engage in interlocking relation with that of theopposed, mating element and a mounting portion 13b adapted to be united to one face of the stringer tape ll,( 12) at a region immediately adjacent a longitudinal marginal edge portion hereafter described.
- the element 13 is further provided with a slope portion 13c extending from the flat mounting portion 131) upwardly toward and terminating short of the longitudinal center axis of the fastener 10 which is indicated in chain-dotted line AA in FIG. 2 and which is in registry with the center axis of the engaging portions 13a of the elements 13.
- Each stringer tape 11,( 12) comprises a flat web portion 11u,(12a) and a longitudinal marginal edge portion llb,(l2b) which is directed upwardly along the slope portions 136 of the fastener elements 13 but is disposed for free movement relative thereto may be seen from FIG. 2.
- the marginal edge portions l1b,(12b are thus tilted upwardly toward each other and each extend slightly beyond the center axis AA shown in FIG. 3, so that they can abut intimately against each other substantially in the form of a rafter when the fastener elements 13 are interlocked by a slider 14 to close the fastener 10 in a manner as illustrated in FIG. 2.
- the marginal edge portions 1111.121 may be preferably reduced in thickness as compared to the web portions 11u,l2u shown.
- the sealing structure herein-above described is advantageous in that the adjacent marginal edge portions 1112.12! at their free edges are allowed to increase the area of their contact surfaces 17, hence in bondage substantially in proportion with increasing external pressure.
- it is rendered possible to maintain sealing ofthe fastener 10 against changing external pressure and further to facilitate the sliding movement of the slider.
- a pressure-sealing slide fastener comprising:
- a. a pair of opposed stringer tapes each including 1. a web portion and 3 2. a marginal edge portion connected thereto and extending at an angle therefrom beyond the center axis of the fastener in its free state: b. a series of interlocking fastener elements each ineluding l. an engaging portion; 2. a flat mounting portion bonded to said web portion. and 3. a sloping portion contiguous to said flat mounting portion and supporting said marginal edge portion in its free state; and c. said marginal edge portions being engageable edgewise with each other and tiltable away from the sloping portion of said elements to increase the angle away from the plane of said tapes as said elements are interlocked.
- a slide fastener according to claim 1 in which said web portion and said marginal edge portion are each of uniform thickness throughout a substantial portion of their extent.
- a slide fastener according to claim 3 in which said marginal edge portion is at all points of lesser thickness than said web portion.
