EXTENSIBLE LEGGED FILM FILE CASE AND PROJECTOR TABLE Filed Aug. 28. 1958 FIG. 3 F76. 4

INVENTOR Ross A. Noa/z Sgm ',ZM BY 3m i mi ATTORNEYG My invention relates to a novel carrying case for transporting movie film and other articles and which is also adapted to serve as a projector supporting stand or table, the latter having novel extensible legs which can be housed within the case to facilitate transportation and storage of same.

Briefly and generally stated, the invention contemplates a device for the purpose specified and for other purposes, which is simple in construction, strong and durable, and which provides meanswhereby extensible sections of the legs can be securely locked in either extended or retracted relationship with respect to the case.

Also contemplated, is a device of this character which is neat and attractive in appearance and will contribute materially tothe appearance of a home.

Gther objects and advantages of the invention will be readily understood and appreciated by those versed in the art upon reference to the accompanying drawing which illustrates a now preferred example of my invention. It is to be understood, however, that the drawing disclosure is to be taken as illustrative, rather than limitative, and that my inventive concept is susceptible of other mechanical expressions within the spirit and scope of the subject matter claimed hereinafter.

In the drawing, wherein the same reference characters have been used to designate the same parts throughout the several views- FIG. 1 is a perspective view of a device embodying my invention;

FIG 2 is a side elevational view partly broken and partly in section, and illustrating the device in use as a projector stand for a motion picture projector;

FIG 3 is a view partly broken and partly in longitudinal section illustrating the novel leg construction; and

FIG. 4 is a longitudinal sectional view of one of the legs taken approximately at right angles to FIG. 3.

Referring to the drawing by reference characters, numeral 8 indicates a case or cabinet for the tiling of reels of movie film, etc., the same having a hinged carrying handle secured to its top and located in a recess 10 thereof so that the handle can be folded down out of the -way when, for instance, the unit is used to support a moving picture projector 7, as indicated in FIG. 2. j

FIGS. 1 and 2 of the drawing also show the cabinet or case 8 as having one side providing a door 11 which is hinged adjacent the casing base as indicated at 12, there being provided a finger piece or lock element 13 to maintain the door closed and to facilitate manipulation of the same.

The extensible legs 14 which project from the bottom of the cabinet are generally indicated by reference character 14 and as will be more clearly understood later on, these legs are adapted to be completely received in the cabinet or case 8 as suggested in FIG. 2.

Since the structure and mounting of each of the legs 14 is the same, a description of one will suiiice for all. Thus, referring to FIGS. 3 and 4, it will be noted that each leg 14 comprises an upper tubular section 15 which is secured by interior case wall-carried bands 19, each leg section 15 being open through the bottom of the case as indicated in FIG. 2. The shiftable telescoping sections of the legs 14 comprise the intermediate tubular section 16, which telescopes into section 15, and the outer or lower section y17 which telescopes into section ited States Patent 16 and carries the rubber or other anti-friction tip 18 at its outer end, as indicated in the drawings.

In carrying out the invention, I provide each upper case or cabinet-carried leg section 15 with an upper interior collar 15a and a lower interior collar 15b which are suitably secured in place by set screws 20, or otherwise. The intermediate leg section v16 which slides in section 15 in spaced relationship to the interior surface of the latter, is in part guided by the lower collar 15b of the leg section 15, and in part by an exterior stop collar 16a which is secured to section 16 inwardly of its upper end by set screw 21 as shown.

The lowermost leg section |17 is spacedly centered for sliding movement in the intermediate leg section 16 by means of an upper exterior stop collar 17a, secured to section y17 by a pin 17b, and in conjunction the lower collar 16b which is interiorly secured, as at 16a, to the intermediate leg section 16.

It is to be noted from an inspection of FIG. 3 that the upper collar of leg section 15 hasits lower edge cut with a bayonet slot 30 providing a lateral pin seating extension 30a; and that its lower collar has a similar slot 23, but located in its upper edge and providing a pin-seating extension 23a. The function of these bayonet slots 30, 23 will be explained later on along with the function of the similar bayonet slots 27, 25 (see FIG. 3) which are provided in the lower and upper edges, respectively, of the

internal collars

28, 16b of the intermediate leg section 16.

When the leg sections 1'6, 17 are fully extended, the upper exterior collar 17a of the lower section 17 will rest on the upper end of the interior collar 16b. With the parts in this position, the fixed and outwardly extending pin 24 of section 17 will have come to rest on the lower edge of the bayonet slot 25 of collar 16b and by a twist action can be finally located in the lateral extension 25a of said slot, so as to maintain 16, 17 against relative longitudinal movement.

Similarly, when the intermediate section 16 has been pulled out until its upper exterior collar 16a rests on the upper end of the lower interior collar 15b of upper section 15, the fixed and exteriorly projecting pin 22 of section 16 will rest on the lower edge of the bayonet slot 23 of collar 15b. Thus, a twistof section 16 in the direction of the lateral extension 23a of slot 23 will lock section 16 against longitudinal movement. Thus, it will be understood, the legs 14 are firmly retained in extended position by reason of the pin and collar slot provided connections noted.

When the

extensible leg sections

16, 17 are to be housedv in the casing-carried uppersection 15, the leg section 17 is given a twist to free its pin 24 from the

slot

25, 25a

of the collar 16b whereupon the outer leg section 17 is slid upwardly until its collar 17a engages the lower end of the interior collar 28 of the intermediate leg section 16. When this happens, the fixed outwardly projecting pin 26 of section 17 above its collar 17a will be at the inner edge of the bayonet slot 27 of the upper collar 28 of section 16, and can be readily located in the lateral slot extension 27a by a twist of section 17 in that direction. Upon accomplishment of this, the rubber tip 18 will be outwardly of but adjacent the lower end of intermediate section 16.

Next the intermediate section 16, with the lower section 17 completely housed therein except for tip 18, s actuated inwardly until its exterior collar 16a engages the lower edge of the upper interior collar 15a of leg section 15. Now the fixed outwardly extending pin 29 of intermediate section 16, which is located above its collar 16a, will engage the upper edge of the bayonet slot 30 of the outer section collar 15a. A twist of section 16 in the direction of the lateral extension 30a Patented June 20, 1961 Y 3 of slot 30 serves to lock section 16 against outward movement.

It is to be understood that when the leg sections are fully telescoped into one another, the tips 18 will project from the bottom of the case 8 slightly so as to provide supports for same, such as are frequently employed with luggage and other items to protect the bottom thereof from wear.

Having thus described my invention, what I claim is:
