Abstract

Retractable telescopic slides extend from a tower unit and are provided with master tongues on the inboard portions of the slides. The slides are roughly positioned and a heavy chassis is lowered onto them. Slots in the chassis first engage the master tongues to force the slides into alignment with the sides of the chassis in the event that they were splayed initially. Further lowering causes additional chassis slots to engage secondary tongues to mount the chassis safely on the slides before pushing it into the frame. Fig. 1 illustrates the initial position of a tower unit frame 1 and slides 2 in an uncontrolled state. Engagement of slots in the chassis (not shown) with master tongues 3 aligns slides 2 against the chassis as shown at 4. Subsequent lowering engages secondary tongues 5 on each slide 2.

Self-Aligning Slides for Heavy Chassis

Retractable telescopic slides extend from a tower unit and are provided with master tongues on the inboard portions of the slides. The slides are roughly positioned and a heavy chassis is lowered onto them. Slots in the chassis first engage the master tongues to force the slides into alignment with the sides of the chassis in the event that they were splayed initially. Further lowering causes additional chassis slots to engage secondary tongues to mount the chassis safely on the slides before pushing it into the frame. Fig. 1 illustrates the initial position of a tower unit frame 1 and slides 2 in an uncontrolled state. Engagement of slots in the chassis (not shown) with master tongues 3 aligns slides 2 against the chassis as shown at 4. Subsequent lowering engages secondary tongues 5 on each slide 2. The sequential operation is obtained by making master tongues 3 higher than secondary tongues 5, as illustrated in Fig.
2.

(Image Omitted)

Fig. 2 shows the slides 2 and chassis 6 in side view and section. Note that master tongue 3 is higher than secondary tongue 5. Master tongue 3 is reinforced at 7 to provide additional strength. An additional fixing arrangement is shown in which a pin 9 on chassis 6 engages a slot in slide 2 for horizontal docking.
