Snap fit lock with release feature

Claim 2

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.

Claim 3

The apparatus of claim 1 wherein said step portion of said locking arm engages said locking frame to secure said first component to said second component.

Claim 4

The apparatus of claim 1 wherein said locking frame aperture is larger than said locking arm projection permitting said locking arm projection to pass therethrough without deforming said locking frame.

Claim 5

The apparatus of claim 1 wherein said locking frame includes 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.

Claim 6

The apparatus of claim 4 wherein said resilient tab is positioned between said pair of side supports.

Claim 7

The apparatus of claim 4 wherein said cam surface operatively interacts with said crossmember to deflect said locking arm toward said second component.

Claim 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 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.

Claim 9

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.

Claim 10

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.

Claim 11

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.
