Abstract
The present disclosure provides an adjustable-length watch strap including a plurality of strap units connected to each other. Each of the plurality of strap units comprising a middle link, a first side link, a second side link, a first connecting member and a lock assembly, the first connecting member comprises a pin and a first elastic member, during transition from the first state to the second state, the first elastic member elastically relaxes thereby moving the pin along the first direction to disengage the first connecting member from the first side link, the middle link of the adjacent strap unit and the second side link, so as to separate two adjacent strap units.
Claims20
An adjustable-length watch strap switchable between a first state in which a length of the adjustable-length watch strap is non-adjustable and a second state in which the length of the adjustable-length watch strap is adjustable, the adjustable-length watch strap comprising:
- a plurality of strap units connected to each other, each of the plurality of strap units comprising:
- a middle link comprising a first side and a second side opposite to the first side;
- a first side link disposed on the first side of the middle link and offset relative to the middle link and comprising a receiving groove defined at a surface of the first side link;
- a second side link disposed on the second side of the middle link, and offset relative to the middle link;
- a first connecting member configured to detachably connect the first side link, a middle link of an adjacent strap unit of the plurality of strap units, and the second side link, and the first connecting member detachably passing through the first side link, the middle link of the adjacent strap unit, and the second side link in sequence;
- and
- a second connecting member arranged parallel to the first connecting member, and connecting the first side link, the middle link, and the second side link, wherein the first side link and the second side link are non-detachably disposed on opposite ends of the second connecting member, respectively;
- and
- an locking assembly arranged in the receiving groove of the first side link and configured to enable or disenable a movement of the first connecting member, so as to control the adjustable-length watch strap to be switched between the first state and the second state,
- wherein the first connecting member comprises a pin and a first elastic member, the pin has a first end and a second end arranged at opposite ends of the pin, the first end is received in the first side link and the second end is received in the second side link when the adjustable-length watch strap is in the first state, the first elastic member is disposed at the second end of the pin and configured to elastically deformed against the pin along a first direction from the second end to the first end of the pin when the adjustable-length watch strap is in the first state,
- wherein during transition from the first state to the second state, the first elastic member elastically relaxes thereby moving the pin along the first direction to disengage the first connecting member from the first side link, the middle link of the adjacent strap unit and the second side link, so as to separate two adjacent strap units.
An adjustable-length watch strap switchable between a first state in which a length of the adjustable-length watch strap is non-adjustable and a second state in which the length of the adjustable-length watch strap is adjustable, and comprising:
- a plurality of strap units connected to each other, each of the plurality of strap units comprising a middle link, a first side link, a second side link, a first connecting member and a lock assembly, wherein the first side link and the second side link are non-detachably disposed on opposite sides of the middle link, respectively, and are offset relative to the middle link,
- wherein the first connecting member detachably connects each two adjacent strap units of the plurality of strap units, and the first connecting member comprises a pin having a first end and a second end opposite to the first end, and a first elastic member connected to the second end of the pin and configured to apply an elastic force to the pin along a width direction of the adjustable-length watch strap, so that the pin is capable of moving along the width direction of the adjustable-length watch strap under the elastic force of the first elastic member,
- when the adjustable-length watch strap is in the first state, a majority portion of the pin is inserted in a middle link of an adjacent strap unit with the first end of the first connecting member being locked in the first side link by the lock assembly;
- when the adjustable-length watch strap is in the second state, the lock assembly is unlocked, and the first end of the pin is at least partially exposed from the first side link, such that two adjacent strap units can be separated by removing the pin,
- wherein the adjustable-length watch strap further comprises a second connecting member arranged parallel to the first connecting member, and connecting the first side link, the middle link, and the second side link.
An adjustable-length watch strap switchable between a first state in which a length of the adjustable-length watch strap is non-adjustable and a second state in which the length of the adjustable-length watch strap is adjustable, and comprising:
- a plurality of strap units connected to each other, each of the plurality of strap units comprising a middle link, a first side link, a second side link, a first rod, an elastic member, a second rod and a lock assembly, wherein the first side link and the second side link are disposed on opposite sides of the middle link, respectively, and are offset relative to the middle link,
- wherein the first rod detachably connects each two adjacent strap units of the plurality of strap units, and the first rod comprises a first end and a second end opposite to the first end, the elastic member is connected to the second end of the first rod and elastically deformable against the first rod in a width direction of the adjustable-length watch strap, the first rod is movable in the width direction of the adjustable-length watch strap in response to the elastic member elastically deformed,
- wherein the second rod is arranged parallel to the first rod, and configured for fixedly connecting the first side link, the middle link, and the second side link,
- in a case that the adjustable-length watch strap is in the first state, a majority portion of the first rod is inserted in a middle link of an adjacent strap unit with the first end of the first rod locked in the first side link by the lock assembly;
- in a case that the adjustable-length watch strap is in the second state, the lock assembly is unlocked, and the first end of the first rod is at least partially exposed from the first side link, such that two adjacent strap units can be separated by removing the first rod.
