Abstract

A detachable mounting clip arrangement according to the present invention includes a mounting clip supported by a support structure. The mounting clip is coupled to the support structure in a manner which allows rotation of the mounting clip between a first or normal position and a second position. A latching mechanism is coupled to the support structure so that when the mounting clip is in the first or normal position the latch is closed and the mounting clip is rotated to the second position, the latch opens. This is accomplished by a CAM pin coupled to the mounting clip which engages a CAM follower slot in a sliding latch member. When the mounting clip is rotated the sliding latch member slides with respect to a fixed latch member thereby opening the latch.

Claims

1. A detachable mounting clip assembly for use with a portable, hand-held device having a housing with clip receiving means on the top and bottom surfaces thereof, said clip assembly comprising:

a base having first and second base members slidable with respect to one another along a longitudinal axis thereof, each of said base members including latch means which, when said base members are in a set position with respect to each other, mate with said top and bottom receiving means respectively to releasable latch said base to the housing;

a mounting clip operatively affixed to said base member; and

a rotatable bracket member, operatively connected to the base, said bracket further including means engaging one of said base members for moving apart said slidable base members along said longitudinal axis when said bracket member is rotated to a predetermined position;

whereby, said latching means detaches from said receiving means when said bracket is rotated to said predetermined position.

2. The detachable mounting clip of claim 1, further including locking means for releasably locking said bracket member in a first position to avoid inadvertent rotation and unlatching of said base members.

3. The detachable mounting clip assembly of claim 2, further including releasing means for selectively unlocking said locking means.

4. The detachable mounting clip assembly of claim 2, further including pivot means for attaching the mounting clip to the bracket member and permitting pivotal movement of said mounting clip between a normal closed position and a normal open position.

5. The detachable mounting clip assembly of claim 4, wherein said locking means further includes releasing means for unlocking said locking means in response to pivoting said mounting clip beyond said normal open position.

6. The detachable mounting clip assembly of claim 5, wherein said locking means further includes a projection carried by one of said base members, the other of said base members including an aperture for receiving the projection in locking engagement, said mounting clip operatively engaging said projection to release the projection from the aperture when the mounting clip is pivoted beyond said normal open position.

7. The detachable mounting clip assembly of claim 2 wherein said locking means further includes releasing means for unlocking said locking means in response to exertion of a predetermined force in a direction which urges said mounting clip toward said base.

8. The detachable mounting clip assembly of claim 7, wherein said locking means further includes a shoulder rivet having a head carried by said bracket means, and

one of said base members includes an arcuate slot having a center aperture, the rivet head being received in said center aperture for locking said bracket member and being releasable from said center aperture when the mounting clip is urged toward said base for allowing rotation of said bracket with said rivet in said arcuate slot.

9. The detachable mounting clip assembly of claim 2, wherein:

said first base member latching means includes a first engagement means, adapted for engaging a first portion of said housing;

said second base member latching means includes a second engagement means, adapted for engaging a second portion of said housing;

said first base member is slidable relative to said second base member so that said first and second engagement means are a first distance apart in a first position and a second distance apart in a second position; and

wherein said first distance is shorter than said second distance.

10. The detachable mounting clip assembly for use with a portable, hand-held device having a housing with clip receiving means on the top and bottom surfaces thereof, said clip assembly comprising:

a base having first and second base members slidable with respect to one another along a longitudinal axis thereof, each of said base members including a latch means which, when said base members are in a set position with respect to each other, mate with said top and bottom receiving means respectively to releasable latch said base to the housing;

a mounting clip operatively affixed to said base member; and

a rotatable bracket member, operatively connected to the base, said bracket further including camming means for moving apart said slidable base members along said longitudinal axis when said bracket member is rotated to a predetermined position, whereby, said latching means detaches from said receiving means when said bracket is rotated to said predetermined positioned;

said bracket member further including pivot means for permitting pivotal movement about a pivoting axis of said mounting clip between a normal open position and a normal closed position;

said bracket member further including rotation means for permitting rotation of said bracket member and mounting clip to said predetermined open position, and said rotation occurs about an axis of rotation substantially normal to said pivoting axis,

said first base member latching means including a first engagement means, adapted for engaging a first portion of said housing;

said second base member latching means including a second engagement means, situated adjacent said second end, adapted for engaging a second portion of said housing;

said first base member being slidable relative to said second base member so that said first and second engagement means are a first distance apart in a first position and a second distance apart in a second position;

wherein said first distance is shorter than said second distance; and

said bracket member further including a cam pin coupled to said mounting clip so that said cam pin rotates about said axis of rotation when said mounting clip is rotated; and

wherein said second base member includes a slotted cam follower engaging said cam pins, so that rotation of said mounting clip is converted to a linear sliding motion of said second coupling member to effect change in the distance between said first and second engagement means.
