Snap fit lock with release feature
First Claim
1. First and second components in combination with a lock mechanism which releasably secures said first and second components together, said lock mechanism comprising:
- a resilient locking arm integrally formed on said first component and extending therefrom, said locking arm having a first side and an opposite second side and a projection extending outwardly from the first side and defining a step portion and a cam surface;
a rigid locking frame integrally formed on and extending outwardly from said second component, said locking frame having a generally rectangular shape and defining a generally rectangular aperture adapted to receive said locking arm in a releasable, securing engagement; and
an integral resilient tab extending outwardly from said second component and into said locking frame aperture, said resilient tab contacting said second side of said locking arm and urging said projection toward securing engagement with said locking frame when said locking arm is inserted into said locking frame.

Abstract
A snap fit locking mechanism is provided for releasably joining a pair of components. The locking mechanism contains a resilient locking arm integrally formed on a first component. The locking arm includes an outwardly extending projection which defines a step portion and a cam surface. A rigid rectangular locking frame extends outwardly from a second component and defines a substantially rectangular aperture adapted to receive and secure the locking arm. A resilient tab extends outwardly from the second component and into the locking frame aperture and is deflected upon insertion of the locking arm into the locking frame aperture. The resilient tab maintains the locking arm in a secure engagement with the locking frame.

7. First and second components in combination with a lock mechanism which releasably secures said first and second components together, said lock mechanism comprising:
-
a resilient locking arm integrally formed on said first component and extending therefrom, said locking arm having a first side and an opposite second side and a projection extending outwardly from said first side and defining a step portion and a cam surface; a rigid locking frame extending outwardly from said second component, said locking frame having a pair of parallel, spaced apart side supports extending perpendicularly from said second component and a crossmember attached to the distal end of each side support and extending therebetween, said crossmember operatively interacting with said cam surface to deflect said locking arm toward said second component; and a resilient tab extending outwardly from said second component and into said locking frame to contact said second side of said locking arm and urge said locking arm outwardly toward said crossmember when said locking frame and said locking arm are engaged.

8. First and second components in combination with a lock mechanism which releasably secures said first and second components together, said lock mechanism comprising:
-
a plurality of resilient locking arms integrally formed on said first component and extending therefrom, each locking arm having a first side and an opposite second side and a projection extending outwardly from the first side and defining a step portion and a cam surface; a plurality of rigid locking frames integrally formed on and extending outwardly from said second component, each locking frame having a generally rectangular shape and defining a generally rectangular aperture adapted to receive one of said locking arms in a releasable, securing engagement, said locking frames registrable with said locking arms; and a plurality of integral, resilient tabs extending outwardly from said second component and into said locking frame apertures, each resilient tab contacting said second side of said locking arm and urging said projection toward securing engagement with said locking frame when said locking arm is inserted into said locking frame.
