Slide arrangement for cable drawer
A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.
1. A method of assembling a slide arrangement, the method comprising the steps of:
a) providing first and second rails each including a primary rail portion and a single interlocking projection that extends from a first end of the primary rail portion to a second end of the primary rail portion;
b) engaging the single interlocking projection of the first rail with a first groove of a center rail; and
c) engaging the single interlocking projection of the second rail with a second groove of the center rail;
d) wherein the first and second grooves are formed on opposite sides of the center rail such that when the single interlocking projections of the first and second rails engage the center rail, the single interlocking projection of the first rail projects from the primary rail portion of the first rail in a first direction and the single interlocking projection of the second rail projects from the primary rail portion of the second rail in a second direction opposite the first direction;
e) wherein each of the first and second rails is slidably secured to the center rail by only the single interlocking projection.
2. The method of claim 1 , wherein the single interlocking projection of each of the first and second rails is attached to the primary rail portion by a neck.
3. The method of claim 2 , wherein each of the first and second grooves of the center rail is at least partly defined by opposing edges that extend toward one another.
4. The method of claim 3 , further including capturing the interlocking projections of the first and second rails within the grooves of the center rail by positioning the neck between the opposing edges, the interlocking projection of each rail having an elongated shape generally transverse to the neck that prevents lateral separation of the rail from the center rail.
5. The method of claim 1 , further including positioning a spool in relation to the first and second rails and the center rail such that the center rail travels at half speed when the first rail travels at full speed relative to the second rail.
6. The method of claim 5 , further including positioning the spool within an aperture formed in the center rail, wherein the spool contacts both the first rail and the second rail.
7. The method of claim 1 , further including securing one of the first and second rails to a drawer and securing the other of the first and second rails to a chassis.
8. The method of claim 7 , further including securing a radius limiter to the center rail.
9. The method of claim 7 , wherein the chassis is constructed to mount to a frame by a mounting arrangement, the mounting arrangement including mounting brackets defining tri-lobed holes and washers having a tri-lobed surface that mates with the tri-lobed holes.
10. A method of assembling a slide arrangement, the method comprising the steps of:
a) providing first and second rails each including a primary rail portion and a single interlocking projection that extends from a first end of the primary rail portion to a second end of the primary rail portion, each single interlocking projection being defined by a neck that attaches to the primary rail portion and an elongated shape that is generally transverse to the neck;
b) engaging the single interlocking projection of the first rail with a first groove of a center rail; and
c) engaging the single interlocking projection of the second rail with a second groove of the center rail;
d) wherein each of the first and second rails is slidably secured to the center rail by only the single interlocking projection, the elongated shape of the interlocking projection of each rail preventing lateral separation of the rail from the center rail.
11. The method of claim 10 , further including positioning a spool in relation to the first and second rails and the center rail such that the center rail travels at half speed when the first rail travels at full speed relative to the second rail.
12. The method of claim 11 , further including positioning the spool within an aperture formed in the center rail, wherein the spool contacts both the first rail and the second rail.
13. The method of claim 10 , further including securing one of the first and second rails to a drawer and securing the other of the first and second rails to a chassis.
14. The method of claim 13 , further including securing a radius limiter to the center rail.
15. The method of claim 13 , wherein the chassis is constructed to mount to a frame by a mounting arrangement, the mounting arrangement including mounting brackets defining tri-lobed holes and washers having a tri-lobed surface that mates with the tri-lobed holes.
16. A method of assembling a slide arrangement, the method comprising the steps of:
providing first and second rails each including a primary rail portion and a single interlocking projection that extends from a first end of the primary rail portion to a second end of the primary rail portion;
engaging the single interlocking projection of the first rail with a first groove of a center rail; and
engaging the single interlocking projection of the second rail with a second groove of the center rail;
positioning a spool in relation to the first and second rails and the center rail such that the center rail travels at half speed when the first rail travels at full speed relative to the second rail
wherein each of the first and second rails is slidably secured to the center rail by only the single interlocking projection.
17. The method of claim 16 , further including positioning the spool within an aperture formed in the center rail, wherein the spool contacts both the first rail and the second rail.
