US 7,677,679 B2 · Slide assembly

Abstract

A slide assembly includes a first slide (10), a second slide (20) slidably attached to the first slide, and a third slide (30) incorporated with a releasing member (50) slidably attached to the second slide. The first slide includes a stop (14) and a block (16). The second slide has a stop piece (28) and a slot (26) for movably receiving a retention pin (40). When the first, second, and third slides are in a fully extended state, the retention pin and the stop piece are resisted by the stop and the block of the first slide respectively, thereby restraining sliding movement between the second slide and the first slide; when the third slide is retracted from the fully extended state to a semi-extended state, the retention pin is lifted by the releasing member and disengaged from the stop, thereby allowing the second slide to retract into the first slide.

Dependent claims

A slide assembly, comprising:

a first slide comprising a stop protruding therefrom, the stop comprising an inclined edge;
a second slide slidably coupled to the first slide, comprising a slot defined therein;
a retention pin movably received in the slot of the second slide, the retention pin having two ends protruding from opposite sides of the second slide respectively;
and
a third slide slidably coupled to the second slide, the third slide including a releasing member, the releasing member comprising an inclined flange;
wherein the second slide is slidable along the first slide from a retracted position to a predetermined extended position where the retention pin is blocked by the stop after one end of the retention pin climbing over the inclined edge of the stop and falling to a bottom of the slot for preventing retraction movement of the second slide at the predetermined extended position;
and
wherein the third slide is slidable along the second slide from an extended position to a semi-extended position where another end of the retention pin is lifted by the inclined flange of the releasing member to disengage the retention pin from the stop of the first slide for allowing retraction movement of the second slide from the predetermined extended position;
wherein the releasing member comprises a body attached to the third slide, the inclined flange of the releasing member is extended perpendicularly from an inclined edge of the body.

A slide assembly comprising:

a first slide comprising a stop and a block protruding from an inner side thereof;
a second slide slidably attached to the inner side of the first slide, the second slide having a slot defined therein, and a stop piece corresponding to the block of the first slide extending therefrom, a retention pin being movable received in the slot with its two ends protruding from two opposite sides of the second slide respectively;
and
a third slide slidably attached to the second slide, the third slide including a releasing member;
wherein the second slide is slidable along the first slide from a retracted position to a predetermined extended position where the retention pin and the stop piece of the second slide are resisted by the stop and the block of the first slide respectively for restraining either retraction or extension movement of the second slide along the first slide;
and
wherein the third slide is slidable along the second slide from an extended position to a semi-extended position where the retention pin is lifted by the releasing member and disengaged from the stop of the first slide for allowing the second slide together with the third slide to retract into the first slide to reach a fully retracted state.

Detailed description992 words

#Referring to FIG. 1, a slide assembly of the preferred embodiment of the present invention includes an outer slide 10, an intermediate slide 20, and an inner slide 30, a retention pin 40, and a releasing member 50.

#Referring also to FIG. 2, the outer slide 10 includes a pair of guideways 12 for allowing longitudinal sliding movement of the intermediate slide 20 in the outer slide 10 and restraining lateral movement of the intermediate slide 20. The outer slide 10 further includes a pair of stops 14 each having an inclined edge 141. The stops 14 are generally triangle-shaped and extended obliquely from the inner side of the outer slide 10. A first block 16 protrudes from the inner side of the outer slide 10.

#The intermediate slide 20 includes a pair of guideways 22 for allowing longitudinal sliding movement of the inner slide 30 in the intermediate slide 20 and restraining lateral movement of the inner slide 30. A second block 24 protrudes from a front portion of the inner side of the intermediate slide 20. A lateral slot 26 is defined in the intermediate slide 20, transverse to a longwise direction of the intermediate slide 20. A stop piece 28 is extended perpendicularly towards the outer slide 10 from the intermediate slide 20 near the slot 26. The retention pin 40 is mounted in the slot 26 of the intermediate slide 20 and capable of moving upwards and downwards along the slot 26. A central portion of the retention pin 40 is received in the slot 26, leaving the two ends of the retention pin 40 protruding from opposite sides of the intermediate slide 20. A width of the slot 26 is approximately equal to a diameter of the central portion of the retention pin 40. A height of the stop piece 28 is about equal to a half of the length of the slot 26.
