Slider for slide fastener
There is provided a slider for a slide fastener. A lock member is swingably supported by a pillar portion which is erected on an upper surface of a body. A cover member covers the pillar portion and the lock member from above. The lock member includes a body portion which is disposed on the upper surface of the body and a claw portion which protrudes from the body portion and enters an element guide path of the body. One side surface of the claw portion is formed with an inclined surface which causes the claw portion to be gradually tapered toward a front end of the claw portion. The other side surface of the claw portion is formed with a stepped portion which causes a plate thickness of the claw portion to be smaller than a plate thickness of the body portion.
1. A slide fastener comprising:
a pair of fastener tapes;
a pair of fastener element rows respectively provided on opposing tape side edge portions of the pair of fastener tapes, the pair of fastener element rows each having a plurality of fastener elements;
a slider configured to engage and disengage the pair of fastener element rows with and from each other; and
a separable end stop including;
a box pin formed at one end portion of one of the tape side edge portions of one of the fastener tapes; and
an insert pin formed at one end portion of another of the tape side edge portions of another of the fastener tapes and which is configured to be inserted into an element guide path of the slider,
wherein the slider includes:
a body forming the element guide path;
a lock member which is swingably supported by a pillar portion which is erected on an upper surface of the body; and
a cover member which covers the pillar portion and the lock member from above,
wherein the lock member comprises a body portion which is disposed on the upper surface of the body and a claw portion which protrudes from the body portion and is configured to enter the element guide path of the body,
wherein the lock member has a plate shape comprising a first main surface and a second main surface opposite the first main surface and a thickness direction of the plate shape of the lock member is defined as a direction perpendicular to the first main surface and the second main surface,
wherein the lock member is attached to the body such that the thickness direction is oriented to a width direction of the slider,
wherein one side surface of the claw portion in the thickness direction is formed with an inclined surface which causes a plate thickness of the claw portion to be gradually tapered toward a tip end of the claw portion, and the insert pin of the separable end stop is configured to come into contact with the inclined surface of the claw portion and push up the claw portion when the insert pin is inserted into the element guide path, and
wherein another side surface of the claw portion in the thickness direction is formed with a stepped portion which causes the plate thickness of the claw portion to be smaller than the plate thickness of the body portion.
2. The slide fastener according to claim 1 , wherein a formation area of the stepped portion is greater than a formation area of the inclined surface in a protruding direction of the claw portion.
3. A slide fastener comprising:
a pair of fastener tapes;
a pair of fastener element rows respectively provided on opposing tape side edge portions of the pair of fastener tapes, the pair of fastener element rows each having a plurality of fastener elements;
a slider configured to engage and disengage the pair of fastener element rows with and from each other; and
a separable end stop including;
a box pin formed at one end portion of one of the tape side edge portions of one of the fastener tapes; and
an insert pin formed at one end portion of another of the tape side edge portions of another of the fastener tapes and which is configured to be inserted into an element guide path of the slider,
wherein the slider includes:
a body forming the element guide path;
a lock member which is swingably supported by a pillar portion which is erected on an upper surface of the body; and
a cover member which covers the pillar portion and the lock member from above,
wherein the lock member comprises a claw portion which is configured to enter the element guide path of the body,
wherein the lock member has a plate shape comprising a first main surface and a second main surface opposite the first main surface and a thickness direction of the plate shape of the lock member is defined as a direction perpendicular to the first main surface and the second main surface,
wherein the lock member is attached to the body such that the thickness direction is oriented to a width direction of the slider, and
wherein one side surface of the claw portion in the thickness direction is formed with an inclined surface, and the insert pin of the separable end stop is configured to come into contact with the inclined surface of the claw portion and push up the claw portion when the insert pin is inserted into the element guide path.
4. The slide fastener according to claim 1 , wherein the plate thickness is substantially uniform in the body portion of the lock member.
