Abstract

A handle mechanism used for driving a lock module in operation includes a handle, a linking member and a transmission rod, wherein the linking member is selectively engaged with the handle and the transmission rod. The handle is unable to drive the lock module in operation by the transmission rod driving and prevents the lock module from damage once an excessive force is applied to the handle when the linking member is not engaged with the handle and the transmission rod. Oppositely, the handle is able to drive the lock module in operation by the transmission rod driving when the linking member is engaged with the handle and the transmission rod.

First claim

What is claimed is:

1. A handle mechanism comprising:
a case;
a handle comprising a holding portion and a shaft portion, wherein the shaft portion is pivotally connected to the case and has an accommodating hole;
a transmission rod driving a lock module in operation, wherein a horizontal axis passes through the transmission rod and the accommodating hole and wherein a first end of the transmission rod is inserted into the accommodating hole such that the first end of the transmission rod in the accommodating hole does not interfere with the shaft portion;
a linking member transversely disposed relative to the transmission rod and selectively engaging the shaft portion of the handle with the transmission rod;
a pushing member having a supporting portion provided to push the linking member toward the transmission rod; and
a motor having a rotation shaft, wherein the supporting portion is engaged with the rotation shaft and the motor drives the pushing member to move the linking member, pushed by the supporting portion, to directly contact the transmission rod in the accommodating hole and wherein, when the linking member is moved to contact the transmission rod, the shaft portion of the handle is engaged with the transmission rod by the linking member and is able to rotate the transmission rod to drive the lock module in operation and wherein, when the linking member is not moved to contact the transmission rod, the shaft portion of the handle is not engaged with the transmission rod and is unable to rotate the transmission rod to drive the lock module in operation.

2. The handle mechanism in accordance with claim 1 , wherein the case comprises at least one constraining member, the pushing member comprises at least one constraining rail, and the constraining member is engaged with the constraining rail such that the constraining member and the constraining rail constrain a longitudinal moving distance of the pushing member.

3. The handle mechanism in accordance with claim 1 further comprising at least one switch electrically connected to the motor, and the pushing member is used for touching the switch to make the motor stop operating.

4. The handle mechanism in accordance with claim 1 , wherein the linking member movably penetrates into the accommodating hole to selectively engage with the shaft portion of the handle and the transmission rod.

5. The handle mechanism in accordance with claim 4 , wherein the shaft portion of the handle comprises a constraining slot and an axial wall, the axial wall surrounds the accommodating hole, the constraining slot disposed at the axial wall penetrates through the axial wall and communicates with the accommodating hole and the constraining slot reveals the first end of the transmission rod.

6. The handle mechanism in accordance with claim 5 , wherein the linking member which corresponds to the constraining slot of the shaft portion is able to penetrate through the constraining slot of the shaft portion and move toward the transmission rod to contact against the transmission rod and is able to move backward from the transmission rod to break contact with the transmission rod.

7. The handle mechanism in accordance with claim 1 further comprising a supporting base having a first pivoting hole and a second pivoting hole which communicates with the first pivoting hole, wherein an included angle is defined between a first axial line passing through the first pivoting hole and a second axial line passing through the second pivoting hole, the transmission rod penetrates into the first pivoting hole, and the linking member penetrates into the second pivoting hole.

8. The handle mechanism in accordance with claim 7 further comprising an elastic member, wherein one end of the elastic member contacts against the supporting base, and the other end of the elastic member contacts against the linking member to prevent the linking member from contacting against the transmission rod when the linking member is not pushed by the pushing member.

9. The handle mechanism in accordance with claim 1 , wherein the pushing member comprises an arc-shaped contact surface, and the linking member contacts against the arc-shaped contact surface.
