Abstract
This invention includes a latch member for a latch assembly, suitable for a removable battery package. The latch member accommodates attachment to a latch coupler of an electronic device. A resilient, springy-metal, deflectable latch member is provided. The latch member includes arms for coupling with a latch coupler, a locking arm for adhering to a plastic housing, and spring arms that cause a torsion element to twist when force is applied to the arms. The torsion element is at least twice as long as it is wide, and provides reliable return force despite a short travel length of the arms. The latch member is suitable for battery packages in which space is a premium.
Claims9
A latch member, comprising:
- a. a bridge member;
- b. at least one arm, the arm having at least one aperture therethrough;
- c. at least one locking tab;
- d. at least one spring arm;
- and
- e. at least one torsion member, the at least one torsion member having a length and a width;
- wherein the length of the at least one torsion member is at least twice the width.
In a latch assembly for a removable battery package having a latch coupler, wherein the removable battery package includes a battery housing having a socket that mates with the latch coupler, a latch member secured within the socket, the latch member being resilient and deflectable, and being biased in a first position, the latch member having a latch portion for engaging the latch coupler, and a button mounted on the latch member, the button being depressible to deflect the latch member to a second position, the improvement comprising:
- at least one torsion member disposed within the latch member, the torsion member having a length and a width;
- wherein the length of the at least one torsion member is at least twice the width.
In a removable battery package having a latch assembly for attaching to an electronic device, the electronic device having a latch coupler, the removable battery package having a battery housing having a socket that mates with the latch coupler, a latch member secured within the socket, the latch member having preloaded cantilever arms connected by a bridge member, the cantilever arms each having a catch for engaging the latch coupler, and a button mounted on the latch member, the button being depressible to deflect the latch member, wherein the preloading of said cantilever arms is achieved by providing cantilever arms bent upwards and away from the plane of the bridge member, the cantilever arms deflectable toward the plane of the bridge member by depressing said button, the improvement comprising:
- at least one torsion member disposed within the latch member, the torsion member having a length and a width;
- wherein the length of the at least one torsion member is at least twice the width
