Abstract

An assembly of a first component and a second component joined by a locking lever connector mechanism includes a first component having an elongated guide rib extending outwardly thereof in a second direction. A flexible latch arm also extends outwardly from the second component at a location spaced from the guide rib to define a narrow slot extending in a first direction. The latch arm has a terminal end with a latch element extending therefrom in a direction laterally away from the slot. The first component has a catch element positioned to engage with the latch element when the first component and the second component are in an assembled relationship. The first component further includes a locking lever having a body portion extending from the first component into the slot to prevent movement of the latch arm laterally away from the catch element. A resilient portion is provided for permitting selective manual deflection of the locking lever out of the slot to permit lateral movement of latch arm away from the catch element to allow the first component and the second component to be disassembled.

Claims

1. The combination comprising:

a first component having an elongated guide rib extending outwardly thereof along a first direction, a flexible latch arm extending outwardly from the first component at a location spaced from the guide rib to define a narrow slot extending in said first direction, said latch arm having a latch element extending therefrom in a direction laterally away from the slot, and,

a second component having a catch element extending outwardly therefrom and positioned to engage with the latch element when the first component and the second component are in an assembled relationship, said second component further including a locking lever having a body portion extending from the second component into said slot when the first component and the second component are in said assembled relationship to selectively prevent lateral movement of the latch arm away from the catch element, said locking lever including a resilient portion for permitting selective deflection of said locking lever out of said slot to permit said lateral movement of said latch arm away from the catch element to allow relative movement between the first component and the second component when the first component and the second component are disassembled.

2. The combination as defined in claim 1 including an actuating portion on said locking lever, said actuating portion extending outwardly of said slot when said body portion is located in said slot.

3. The combination as defined in claim 1 wherein said body portion has a width substantially equal to the width of said slot.

4. The combination as defined in claim 1 wherein said second component includes a guide wall extending parallel to said locking lever and, in combination therewith, defining a recess that receives the guide rib when the first and second components are in said assembled relationship.

5. The combination as set forth in claim 4 wherein said first and second components are molded from plastic, and further wherein said latch arm is molded of plastic integrally with said first component and said locking lever is molded of plastic integrally with said second component.

6. The combination as set forth in claim 4 wherein the locking lever is of substantially uniform width throughout its length.

7. The combination of claim 1 wherein said latch arm includes an end surface contoured to engage under the locking lever and deflect the locking lever outwardly during movement of the first and second components toward said assembled relationship.

8. The combination of claim 7 including cooperating surface means on said latch element and said catch element to produce lateral movement of said latch arm during movement of the first and second components toward said assembled relationship.

9. The combination as defined in claim 8 wherein the latch arm is spaced a distance from the guide rib only slightly greater than the width of the locking lever.
