Abstract

A structural support mounting means for precision, telescoping, linear slide mechanisms of the type having an outer slide member and an inner slide member, each being held in sliding relationship by ball bearings or the like, the balls being operably disposed in a ball retainer between the inner and outer slide members. The structural support mounting means is defined by an elongated rail having oppositely disposed channels formed longitudinally therein, to structurally support and receive a pair of oppositely arranged slide mechanisms, wherein each adjacent slide member is affixed to a central, load-carrying bracket for longitudinal movement of the load secured to the bracket thereof, and wherein an elongated, structural-reinforcing bar member is adapted to be received and fixedly mounted within the inner slide member. Both the rail and the reinforcing bar members are formed from an extruded aluminum material whereby structural strength, load-carrying capacity, and extended, load-carrying capacity are established with respect to the outer and inner slide members.

Claims

1. A structural support mounting means in combination with precision, telescoping, linear, ball-bearing slide mechanisms having inner and outer slide members and ball bearings disposed therebetween, wherein the improvement comprises:

an elongated rail housing having side and end walls defining a longitudinal barrel therein, wherein at least one end wall thereof is provided with a longitudinal slot communicating with said barrel;

a pair of support cradles disposed in said barrel and formed in each of said side walls, wherein a slide mechanism is fixedly retained in each oppositely disposed cradle;

a pair of inner slide members, each having a longitudinally extending bottom wall and oppositely facing ball raceways along the side edges thereof;

a reinforcing bar member formed to be received and mounted within said inner slide member;

a mounting bracket for attaching a load thereto, said bracket being arranged to move with said slide mechansim; and

means for attaching said rail housing to a substantially fixed structure.

8. A structural support mounting means as recited in claim 1, wherein said side walls are independent of each other, and at least one side wall thereof being arranged to be moved relative to the other side wall thereof;

and wherein said mounting bracket is secured to said movable side wall.

9. A structural support mounting means as recited in claim 8, wherein a second rail housing is positioned in adjacent, parallel relationship to the first rail housing, wherein each rail housing has respective, movable side walls in a juxtaposed arrangement, whereby said mounting bracket is secured to each movable side wall.

2. A structural support mounting means as recited in claim 2, wherein said mounting bracket is secured directly to each adjacent inner slide member, whereby said bracket slidably moves in said slot with the movement of said inner slide members.

3. A structural support mounting means as recited in claim 2, wherein said means for attaching said rail housing comprises a pair of oppositely disposed leg members integrally formed with said rail housing.

4. A structural support mounting means as recited in claim 3, wherein said rail housing includes an upper end wall and a lower end wall, and wherein said elongated slot is disposed in said lower end wall, allowing said mounting bracket to extend downwardly and outwardly therefrom, whereby a load can be supported in a hanging mode below said rail housing.

5. A structural support mounting means as recited in claim 3, wherein said rail housing includes an upper end wall and a lower end wall, and wherein said elongated slot is disposed in said upper end wall, allowing said mounting bracket to extend upwardly and outwardly therefrom, whereby a load can be supported in a carrying mode above said rail housing.

6. A structural support mounting means as recited in claim 2, including a second rail housing secured to said first mentioned rail housing, said second rail housing being located below said first rail housing and being provided with parallel slots disposed in each end wall thereof, said mounting bracket being secured to said inner slide members of both slide mechanisms disposed in each rail housing, extending outwardly from said second rail housing through said slots thereof.

7. A structural support mounting means as recited in claim 2, including:

a second and a third rail housing, each having at least one elongated slot disposed therein, wherein said first mentioned rail housing and said second rail housing are oppositely disposed to each other, having respective slots thereof facing inwardly in parallel alignment; and

a carriage plate slidably supported within said first and second housings, said plate being affixed to each pair of inner slide members for longitudinal movement therewith, wherein said third rail housing is mounted to said carriage plate to move therewith, said mounting bracket being secured to said inner walls of said slide mechanisms disposed in said third rail housing.

10. A structural support mounting means for precision, telescoping or linear, ball-bearing, slide mechanisms comprising:

an outer slide member of generally channel-shaped configuration, and having a longitudinally extending bottom wall and oppositely arranged ball raceways along the side edges of the bottom wall;

an inner channel-shaped slide member having a longitudinally extending bottom wall and oppositely facing ball raceways along the side edges thereof;

ball bearings disposed in adjacent raceways of the respective outer and inner slide members;

an elongated rail housing having side and end walls defining a longitudinal barrel therein, wherein at least one wall thereof is provided with a longitudinal slot communicating with said barrel;

a pair of supporting cradles arranged oppositely to each other and formed in said side walls thereof, whereby the respective outer walls are received in each of said cradles;

a reinforcing bar member formed to be received and mounted within said inner slide member;

a mounting bracket for attaching a load thereto, said bracket being secured to said slide mechanisms for movement therewith, and

means for attaching said rail housing to a substantially fixed structure.
