Abstract

A slide comprising a pair of telescopically related track members, ball bearings supporting the track members for relative longitudinal movement, a cage or retainer for the ball bearings longitudinally movable relative to the track members, and a device for locking the retainer against movement from a predetermined locking position relative to one of the track members when the other of the track members is moved longitudinally out of engagement with the said one track member. The locking device includes a locking member carried on the retainer and a cooperating locking member carried on the said one track member, the locking members being engageable when the retainer is in its said locking position and the said other track member is disengaged from the said one track member.

Claims

1. A slide comprising a first elongated track member formed to provide a downwardly facing longitudinal raceway and an upwardly facing longitudinal raceway, a second elongated track member formed to provide an upwardly facing longitudinal raceway in mating registry with the first said downwardly facing raceway and a downwardly facing longitudinal raceway in mating registry with the first said upwardly facing raceway, bearings disposed in said mating raceways to support said track members for relative longitudinal movement, bearing retainer means for maintaining the longitudinal spacing between said bearings in said raceways, said retainer means being longitudinaLly movable relative to said track members, and means for locking said retainer means against any appreciable movement from a predetermined locking position relative to one of said track members when the other of said track members is moved longitudinally out of engagement with said one track member, said locking means including a locking member carried on said retainer means and a cooperating locking member carried on said one track member, said locking members being engageable when said retainer means is in its said locking position and said other track member is disengaged from said one track member.

2. The slide of claim 1 in which said other track member is proportioned and designed to disengage said locking members when said other track member is moved into reengagement with said one track member.

3. The slide of claim 1 in which said one track member is provided with opposite end portions, said cooperating locking member being disposed adjacent one end portion of said one track member, said one end portion being provided with stop means preventing movement of said retainer means longitudinally out of engagement with said one end portion.

4. The slide of claim 3 including second stop means for preventing said other track member from moving longitudinally out of engagement with the opposite end portion of said one track member.

5. The slide of claim 4 in which said other track member is proportioned and designed to disengage said locking members when said other track member is moved longitudinally into reengagement with said one end portion.

6. The slide of claim 5 in which the first said locking member is biased toward engagement with said cooperating locking member, the first said locking member including an actuator portion projecting into the path of said other track member as it moves longitudinally into engagement with said one end portion.

7. The slide of claim 1 in which one of said locking members is biased toward locking engagement with the other of said locking members, said one of said locking members including an actuator portion projecting into the path of said other track member as it moves longitudinally relative to said one track member, said other track member being proportioned and designed to engage said actuator portion to prevent locking engagement of said locking members while said track members are engaged.

8. The slide of claim 1 in which said raceways are in vertical registry to provide upper and lower mating raceways, said retainer means including an elongated member having a central body portion and upper and lower flange portions extending respectively into said upper and lower raceways to engage the bearings therein, the first said locking member being biased toward engagement with said cooperating locking member, the first said locking member being carried on said central body portion and including an actuator portion projecting into one of said raceways, said other track member being effective to engage said actuator portion to prevent locking engagement of said locking members while said track members are engaged.

9. The slide of claim 8 in which said one track member includes a longitudinally extending central body portion parallel and adjacent to said central body portion of said retainer means, said cooperating locking member being carried on the central body portion of said one track member.

10. The slide of claim 9 in which said central body portion of said retainer means is formed as a channel section opening toward said one track member and including upper and lower longitudinally extending wall sections, the first said locking member being disposed within said channel section, and said cooperating locking member being disposed to project into said channel section.

11. The slide of claim 10 in which one of said wall sections is provided with an aperture through which said portion extends to project into one of said raceways.

12. A slide comprising a pair of telescopically related track members, balL bearings supporting said track members for relative longitudinal movement, retainer means for said ball bearings, said retainer means being longitudinally movable relative to said track members, and means for locking said retainer means against any appreciable movement from a predetermined locking position relative to one of said track members when the other of said track members is moved longitudinally out of engagement with said one track member, said locking means including a locking member carried on said retainer means and a cooperating locking member carried on said one track member, said locking members being engageable when said retainer means is in its said locking position and said other track member is disengaged from said one track member.

13. The slide of claim 12 in which said other track member is proportioned and designed to disengage said locking members when said other track member is moved into reengagement with said one track member.

14. The slide of claim 12 in which said one track member is provided with opposite end portions, said cooperating locking member being disposed adjacent one end portion of said one track member, said one end portion being provided with stop means preventing movement of said retainer means longitudinally out of engagement with said one end portion.

15. The slide of claim 12 in which one of said locking members is biased toward locking engagement with the other of said locking members, said one of said locking members including an actuator portion projecting into the path of said other track member as it moves longitudinally relative to said one track member, said other track member being proportioned and designed to engage said actuator portion to prevent locking engagement of said locking members while said track members are engaged.
