Claims. Cl. 21146) This invention relates to slides and more specifically horizontal pivot slides.

Broadly, it is an object of the invention to provide a slide which can be attached to a horizontal member to provide a means for hanging and storing articles, such as samples, permitting such articles to be pulled outwardly for display purposes.

More specifically, it is an object of the invention to provide a means for storing and hanging materials, such as rug and fabric samples for display purposes so that a salesman can easily pull out the rug or sample he wishes to display and then swing the rug or sample around to any desired position for examination by the customer.

A further object of the invention is to provide a rotatable and extensible slide for a storage and display cabinet in which articles, samples and inventory of certain types may be stored and easily displayed to advantage when desired.

For a fuller understanding of the nature and objects of the invention, reference is had to the following detailed description, in connection with the accompanying drawings, in which:

Fig. 1 is a perspective view of a storage cabinet partly broken away, showing several slides of a bank of slides holding two rug samples (as one example of use) back to back, with the pivot channel of the slide extended and rotated 90.

Fig. 2 is an enlarged perspective view of the horizontal pivot slide, partly broken away, showing the pivot channel in dotted position parallel to the slide so that the track and channel may be retracted.

Fig. 3 is a side view of the pivot slide in retracted position.

Fig. 4 is a side view of the pivot slide in partially extended position, parts being broken away to show details of construction.

Fig. 5 is an end view of the pivot slide without any goods being held within the pivot channel.

Referring to the drawings, numeral represents a pivot slide comprising a channel 11, which may be fastened by screws through screw holes 37 under a horizontal shelf or top member 12 of a storage cabinet 13 (shown in Fig. 1), a center track 14 and a pivot channel 15. Between the channel 11 and the center track 14 there is a U-shaped ball spacer 16 containing entrapped ball bearings 17 to provide easy rolling of the center track 14. T he pivot channel is attached at its central point to the end of the center track 14 by means of a flat head master screw 18 having a washer 19 and an elastic stop nut 29 at its lower end, permitting the channel 15 to rotate. Pivot channel 15, however, is prevented from rotating by means of the ball 21 and spring 22 recessed in center track 14 which maintains a constant pressure upon the ball 21. A set screw retains the ball 21 and spring 22 within the retaining hole 23. The ball 21 projects out of its retaining hole 23 and into a corresponding hole 24 in the pivot channel 15. The ball 21 prevents the pivot channel 15 from rotating away from a position parallel to the channel 11 until a suflicient rotating force on the pivot channel 15 cams the ball 21 up and allows the pivot channel 15 to rotate.

The pivot channel 15 has two holes 24, 26, each spaced apart from the master screw 18 the same distance as set screw 25 so that the ball 21 will fall into holes 24 or 26, and retain the pivot channel 15 in parallel position with the slide or channel 11 every so that the pivot channel 15 is in position for sliding back into the cabinet 13. It will be seen that the pivot channel 15 can rotate 360 and is retained in parallel relation to the slide 10 by means of the ball 21 and spring 22.

Pivot channel 15 has a series of grip plates 28 which have tapped holes and are operated by Allen head cap screws 29 which act as lead screws for moving the plates 28 transversely of the pivot channel 15. One or two materials, such as rug samples 30, shown back to back, are passed into the pivot channel 15 and are gripped and retained therein by a multiplicity of grip plates 28, three of which are shown herein for illustrative purposes only, since any number may be used depending upon the type and weight of the article to be gripped. The grip plates 28 press the articles 30' against the edge 33 of the inner flange of the pivot channel 15 to retain it against displacement.

After the article or articles, such as the rug samples 30 shown, are thus gripped and retained within the pivot channel 15, the slide may be extended and the pivot channel 15 may be pivoted360 to display both faces of the rug samples 30.

The center track 14 is prevented from leaving the channel 11 since the rear locking pin 34, which passes through a transverse hole adjacent the rear end of the center track 14 abuts the rear end of the U-shaped ball spacer 16. The front end of the ball spacer 16 abuts the extruded stop 31 when the pivot channel 15 and center track 14 are extended thus preventing the channel 15 and center track 14 from leaving the slide 10. In the positions shown in Figs. 3 and 4, the lock pins 34 and 36 strike the ball spacer 16 at approximately the same instant that the ball spacer 16 strikes the extruded stops 31, 35 of the channel 11 in the retracted and extended positions. When the pivot channel 15 and center track 14 are retracted, the rear end of the ball spacer 16 abuts the rear extruded stop 35 and the front locking pin 36 abuts the front edge of the U-shaped .ball spacer 16 preventing the inner end of the center track 14 from striking the rear of the storage cabinet 13. The travel of the ball spacer 16 equals half of the total travel of the track 14 and in the intermediate posi tion, that is when the track 14 has completed one half of the total travel from front to rear and vice versa, the ball spacer 16 is positioned halfway between the stops 31, 35.

In assembling the slide, the stop 31 or stop 35 is extruded only, the slide is then assembled with the ball spacer 16 and then the other stop 31 or 35 is extruded to retain the parts together.

When the pivot channel 15 is slid into the cabinet 13 the end of the pivot channel 15 should be flush with the end of channel 11, as shown in Figs. 1 and 3.

It is obvious that the grip plates 28 and the inner ends of the pivot channel may be formed dilferently than shown, as for example, a series of pointed members for gripping fabric samples, or plates 28 may be extended below the inwardly directed flanges of the pivot channel to permit various attachments to be added, such as bolts, etc. for attaching other articles or samples, such as various kinds of wood, plastic, or compositions primarily used for display samples.

It is also obvious that various changes may be made in the details of construction and arrangement of parts without departing from the general spiritofithe invention.
