Abstract
In sliding clasp fastening means comprising longitudinally extending mating strips and a U-shaped sliding clasp providing a channel fitting over the strips, the channel width tapering in the longitudinal direction of the strips and having adjacent the end thereof of greater width a pillar which fits between and holds the strips apart so that reciprocal movements of the clasp cause engagement or disengagement of the strips, the provision on one or both sides of the channel of means adapted to receive a tool operable to effect resilient separation of the sides of the channel to facilitate fitting of the clasp over the strips.

Sliding clasp fastening means comprising longitudinally extending mating strips having complementary male and female cross-sections and a sliding clasp of a generally U-shaped cross-section providing a channel fitting over the strips, the channel width tapering in the longitudinal direction of the strips and having, adjacent the end thereof of greater width, a pillar which fits between and holds apart the strips whereby, upon movement of the clasp along the strips with the pillar leading in the direction of movement the strips are forced into interlocking engagement by the sides of the channel whilst movement of the clasp in the reverse direction causes the pillar to effect separation of the strips, characterised in that the clasp is formed at least at one side of a central longitudinal plane thereof extending between and generally parallel with the sides of the channel with means adapted to receive a tool operable to effect resilient separation of the sides of the channel to facilitate fitting of the clasp over the strips.
A sliding clasp for use in sliding clasp fastening means of the kind comprising longitudinally extending mating strips having complementary male and female cross-sections and a sliding clasp of generally U-shaped cross-section providing a channel fitting over the strips, the channel width tapering in the longitudinal direction of the strips and having, adjacent the end thereof of greater width, a pillar which fits between and holds apart the strips whereby, upon movement of the clasp along the strips with the pillar leading in the direction of movement the strips are forced into interlocking engagement by the sides of the channel whilst movement of the clasp in the reverse direction causes the pillar to effect separation of the strips, characterised in that the clasp is formed at least at one side of a central longitudinal plane thereof extending between and generally parallel with the sides of the channel with means adapted to receive a tool operable to effect resilient separation of the sides of the channel to facilitate fitting of the clasp over the strips.
In sliding clasp fastening means comprising longitudinally extending mating strips having complementary male and female cross-sections and a sliding clasp of generally U-shaped cross-section providing a channel fitting over the strips, the channel width tapering in the longitudinal direction of the strips and having, adjacent the end thereof of greater width, a pillar which fits between and holds apart the strips whereby, upon movement of the clasp along the strips with the pillar leading in the direction of movement the strips are forced into interlocking engagement by the sides of the channel whilst movement of the clasp in the reverse direction causes the pillar to effect separation of the strips, the method of mounting the clasp on the mating strips comprising gripping the clasp in a tool, operating the tool to increase the force exerted thereby on the clasp so as to effect resilient separation of the sides of the clasp, clamping the mating strips in disengaged facing relationship, advancing the clasp to the strips so as to engage the pillar thereof between the strips and the sides of the clasp respectively with the exterior of the strips, and relasing the force exerted by the tool on the clasp thereby to secure the clasp to the strips.
