Abstract

A front-mount type interlocking sliding rail assembly includes a sliding rail assembly formed of an outer rail, an intermediate rail and an inner rail, a bracket affixed to the outer rail, a swivel member pivoted to the bracket and having two opposite protruding blocks and an actuating block, first limiter and second limiter disposed at two opposite sides and movable by the swivel member, a switching block affixed to the inner rail and having two opposing wings respectively suspending in between a base portion and two stop flanges of the bracket, and a push member located on one wing and adapted for pushing the actuating block to bias the swivel member.

Claims

1. A front-mount type interlocking sliding rail assembly, comprising:

a sliding rail assembly, said sliding rail assembly comprising an outer rail, an intermediate rail slidably mounted in said outer rail and movable in and out of said outer rail and an inner rail slidably mounted in said intermediate rail and movable in and out of said intermediate rail;

an interlocking mechanism, said interlocking mechanism comprising a bracket affixed to a front end of said outer rail, said bracket comprising a base portion, two sidewalls respectively spaced from said base portion at two opposite lateral sides in a parallel manner and two stop flanges respectively protruded from said sidewalls and facing said base portion, a swivel member pivotally connected to said base portion of said bracket, said swivel member comprising two protruding blocks symmetrically disposed at two opposite ends thereof and an actuating block extended from one lateral side thereof, and a first limiter and a second limiter disposed at two opposite sides relative to said swivel member and movable by the swivel member when said swivel member is biased relative to said bracket; and

a switching mechanism, said switching mechanism comprising a switching block affixed to a front end of said inner rail and having two wings disposed at two opposite lateral sides thereof and respectively suspending in between said base portion and said stop flanges of said bracket, a push member adapted for pushing said actuating block of said swivel member to bias said swivel member relative to said bracket, said push member having a first push block and a second push block disposed at two opposite sides.

2. The front-mount type interlocking sliding rail assembly as claimed in claim 1, wherein said first push block and said second push block of said push member are respectively connected to a distal end of the associating wing.

3. The front-mount type interlocking sliding rail assembly as claimed in claim 1, wherein said bracket further comprises a pivot pin extended from said base portion;

said swivel member has a pivot hole located on a middle part thereof and pivotally coupled to said pivot pin of said bracket.

4. The front-mount type interlocking sliding rail assembly as claimed in claim 1, wherein said first limiter and said second limiter each have a bearing face;

the protruding blocks of said swivel member each have a push face adapted for pushing the bearing faces of said first limiter and said second limiter to move said first limiter and said second limiter away from said bracket and a bearing face for stopping against bearing faces of said first limiter and said second limiter.

5. The front-mount type interlocking sliding rail assembly as claimed in claim 1, wherein said push member is located on one wing adjacent to said actuating block of said swivel member;

said actuating block of said swivel member comprises a first push face pushable by said first push block of said push member and a second push face pushable by said second push block of said push member.

6. The front-mount type interlocking sliding rail assembly as claimed in claim 1, wherein said switching mechanism further comprises a locating block fixedly mounted in a front end of said intermediate rail, said locating block comprising a mounting space and two protruding portions at two sides of said mounting portion, and a positioning block extended from said switching block, said positioning block comprising two positioning grooves disposed at two opposite lateral sides thereof and respectively engaged with the protruding portions of said locating block.
