Primary ExaminerJ. Franklin Foss Attorney, Agent, or Firm-Burmeisten, Palmatier & Hamby [57] ABSTRACT The present invention provides a stand which can be 10 Claims, 8 Drawing Figures PATENTEB W27 [975 SHEET 2 0b 46/ 24 BW 35M REDUCED WIDTH T JIi llll siw l f ADJUSTABLE STAND FOR ELECTRONIC CALCULATORS OR THE LIKE This invention relates to a new and improved adjustable stand for holding an electronic calculator or any other suitable device, such as an adding machine or some other type of office machine.

One object of the present invention is to provide a new and improved stand which will hold an electronic calculator or the like at an inclined angle, so that the calculator can be used more easily, and so that the display of the electronic calculator can be read much more easily than would otherwise be the case.

A furter object is to provide a new and improved stand which comprises a plurality of easily assembled pieces, so that the stand can be knocked down for shipment.

Another object is to provide such a new and improved stand which can be adjusted to the desired size during the process of assembly.

A further object is to provide such a new and improved adjustable stand which can be manufactured very economically, so that the stand can be sold at a low price.

Generally, the illustrated stand of the present invention comprises four easily assembled panels or members so that the stand can be shipped in a disassembled or knocked down condition. Thus, the stand comprises left and right side panels, together with front and rear panels. Disengageable fasteneing elements are provided to connect the front and rear panels to the side panels. The upper edges of the side panels are preferably inclined and may be provided with flanges or ledges for supporting an electronic calculator or the like at an inclined angle. Fastening elements are provided on the front and rear panels for engagement with mating elements on the side panels. For example, the fastening elements on the front and rear panels may take the form of pins adapted to be received in openings formed in flanges on the side panels. The front and rear panels preferably comprise a plurality of modules separated by score marks or the like. Fastening elements are formed on the various modules so that each module is complete in itself. Thus, the front and rear panels can be adjusted to the desired width by cutting off one or more of the modules along the score marks. The pins or other fastening elements on the front and rear panels may then be engaged with the openings or other mating elements on the side panels. Flexible flanges are preferably provided on the side panels to retain the front and rear panels against accidental disconnection from the side panels. The panels are preferably made-of an economical resinous plastic material which can be easily be cut with ordinary scissors.

Further objects, advantages and features of the present invention will appear from the following description, taken with the accompanying drawings, in which:

FIG. 1 is a perspective view showing an adjustable stand to be described as an illustrative embodiment of the present invention. 7

FIGS. 2 and 3 are fragmentary plan views, taken generally as indicated by the lines 2-2 and 3-3 in FIG. 1.

FIG. 4 is a view similar to FIG. 1, but with the stand disassembled.

FIG. 5 is a fragmentary plan view illustrating the manner in which the front and rear panels are assembled with the side panels, the view being taken generally as indicated by the line 5-5 in FIG. 4.

FIG. 6 is a fragmentary elevation showing the manner in which one or more of the modules may be severed from the front and rear panels.

FIG. 7 is a vertical section, taken generally along the line 7--7 in FIG. 1.v

FIG. 8 is a bottom view of the stand, showing the manner in which it can be adjusted to various widths.

As just indicated, the drawings illustrate an adjustable stand 10 which will find many applications, but is particularly well adapted for holding an electronic calculator 12, shown in broken lines in FIG. 7. The stand 10 may also be used with various other machines or devices, such as adding machines or other office equipment.

It will be seen that the stand 10 holds the calculator 12 in a raised, inclined position, in which it may be used much more conveniently than when the calculator is lying flat on a desk top or other supporting surface. Moreover, the readout or display on the calculator 12 is rendered much more visible when the calculator is mounted on the adjustable stand 10. As will be described in detail presently, the stand 10 may be adjusted to accomodate electronic calculators or the like of a wide range of sizes.

It will be seen from FIGS. 1 and 4 that the illustrated stand 10 comprises left and right side panels or members 14a and b, together with front and rear panels or members 16a andb, removably connected between the side panels. The illustrated side panels 14a and b have inclined flanges orledges 18a and b, adapted to support the electronic calculator 12 or some other similar device. The ledges 18a and b project inwardly from vertical side walls 20a and b, which may be generally trapezoidal in shape, as will be evident from FIGS. 1 and 4. Preferably, portions of the side walls 20a and b project upwardly from the ledges 18a and b as upwardly projecting flanges 22a and b, adapted to confine the electronic calculator 12 so that it will be retained on the ledges 18a and b against accidental displacement. Reinforcing flanges 24a and b may be arranged to project inwardly from the side walls 20a and b along their lower edge portions.

It will be understood that each of the side panels 14a and b may be molded in one piece from any suitable resinous plastic material, such as polyethylene, polypropylene, polystyrene or the like.

The illustrated front and rear panels or members 16a and b are in the form of plates or sheet members, each of which may be molded in one piece from any suitable resinous plastic material, such as those just mentioned. Of course, the panels 114a and b and 16a and b may also be made of any other suitable materials. The front panel 16a is preferably lower in height than the rear panel 16b, because of the trapezoidal shape of the side panels 14a and b.

Disengageablefastening elements are preferably provided to connect the front and rear panels 16a and b to the side panels 14a and b. These fastening elements are preferably formed integrally with the various panels. As shown, such fastening elements preferably comprise pins 26a and b projecting from the front and rear panels 16a and b. The pins 26a are arranged in a series of pairs, projecting rearwardly from the front panel 16a. Similarly, the pins 26b preferably are'arran'ged'in a series of pairs, projecting forwardly from the rear panel 16b. The pins 260 and b are spaced at intervals along the front and rear panels 16a and b.

The pins 26a and b on the front and rear panels 160 and b are adapted to mate with fastening elements on the side panels 14a and b. Such fastening elements may take the form of openings 28a and b and 30a and b, formed in front and rear flanges 32a and b and 34a and b, projecting laterally on the side members 14a and b. Two of the openings 28a and b are formed in the vertical front flanges 32a and b. Similarly, two of the openings 30a and b are formed in the rear vertical flanges 34a and b.

It will be evident that the endmost pairs of pins 26a plug into the front openings 28a and b. Similarly, the endmost pairs of pins 26b on the rear panel 16b plug into the openings 30a and b in the rear vertical flanges 34a and b.

Retaining elements are preferably provided to retain the front and rear panels 16a and b on the side panels 14a and b against accidental disconnection. As shown, such retaining elements are provided on the side panels 14a and b, in the form of front retaining flanges 36a and b and rear retaining flanges 38a-and b. As shown to best advantage in FIGS. 1 and 3, the front retaining flanges 36a and b are adapted to overlap the lateral edge portions of the front panel 16a. Similarly, as shown in FIGS. 1 and 2, the rear retaining flanges 38a and b are adapted to overlap the lateral edges of the rear panel 16a and b. In this way, the front and rear panels 16a and b are held captive on the side panels 14a and b against accidental disconnection.

The front and rear panels 16a and b, as well as the front retaining flanges 36a and b and the rear retaining flanges 38a and b, are sufficiently flexible to permit easy assembly of the stand 10, despite the overlapping of the front and rear panels by the retaining flanges. FIG. 5 illustrates the manner in which the front panel 16a and the left-hand front retaining flange 36a can be flexed to permit the insertion of the endmost pins 26a into the openings 28a in the flange 32a, while the end of the front panel 16a is simultaneously inserted behind the retaining flange 36a. It will be seen that vertical channels 40a and b are formed between the vertical flanges 32a and b and the retaining flanges 36a and b. The ends of the front panel 16a are adapted to be inserted into the channels 40a and b. Similarly, the vertical channels 42a and b are formed between the vertical flanges 34a and b and the retaining flanges 38a and b. The ends of the rear panel 16b are adapted to be inserted into the channels 42a and b. The rear panel 16b and the rear retaining flanges 38a and b are sufficiently flexible to permit the insertion of the rear panel 16b, in a manner similar to that illustrated in FIG. 5.

It will be seen that the front vertical flanges 32a and b and the front panel 160 extend substantially above the inclined ledges 18a and b, and thus are effective to act as stops to retain the electronic calculator 12 on the ledges, so that the calculator cannot slide forwardly off the ledges 18a and b. This retaining action is clearly illustrated in FIG. 7.

If desired, the sidepanels or members 14a and b may be fitted with non-skid feet 44, made of natural or syn- As already indicated, the stand 10 is adjustable to accomodate electronic calculators 12 or other devices of various sizes. In the illustrated construction, such adjustability is achieved by constructing the front and rear panels 16a and b so that they comprise a plurality of modules 48a and b. The vertical boundaries between the individual modules are preferably defined by providing vertical score marks or grooves 50a and b between the modules 48a and b. Each module 48a is complete in itself, in that it comprises its own pair of the fastening pins 26a, as will be evident from FIGS. 3, 5 and 6. Similarly, each of the rear modules 48b comprises its own pair of the fastening pins 26b and thus is complete in itself.

To adjust the width of the stand 10, one or more of the front modules 48a may be severed or otherwise removed from the front panel 16a. A corresponding number of the rear modules 48b may be severed or otherwise removed from the rear panel 16b. An ordinary pair of scissors may be employed to cut off the unneeded modules 48a and b. Preferably, the front and rear panels 16a and b are made of a relatively soft resinous plastic material which can easily be cut with ordinary scissors.

It will be seen that the score marks or grooves 50a and b are positioned midway between the adjacent pairs of the fastening pins 26a and b. The provision of the score marks or grooves 50a and b makes it easy to cut off the modules 48a and b along the correct boundary lines. However, the score marks or grooves 50a and b may be omitted, if for any reason they are not desired.

The adjustable stand 10 can be shipped in a disassembled or knocked down condition. In this way, the stand can be packaged compactlyfor shipment.

Before the stand is assembled for use, it can be adjusted to the desired width, to accomodate any particular electronic calculator or other device. FIG. 8 shows the maximum width of the stand in full lines, and reduced width in broken lines. As already indicated, the width of the stand can be reduced by cutting off one or more of the modules 48a and b from the front and rear thetic rubber, or some other suitable material, ce-

panels 16a and b. An ordinary pair of scissors can be used to cut off the unneeded modules along the score lines 50a and b. The length of the front and rear panels 16a and b is made slightly greater than the width of the electronic calculator.

The stand is assembled by mounting the front and rear panels 16a and b between the side panels 14a and b. For example, the rear panel 16b can be connected first between the side panels 14a and b. The rear panel 16b and the rear retaining flanges 38a and b can be flexed sufficiently to permit the insertion of the pins 26b into the openings 30a and b, while the ends of the rear panel 16b are inserted intothe channels 40a and b between the vertical flanges 28a and b and the retaining flanges 36a and b. The front panel 16a is then connected between the side panels 14a and b by flexing the front panel and the retaining flanges 36a and b, in the general manner illustrated in FIG. 5, so that the pins 26a can be inserted into the openings 28a and b, while the ends of the front panel 16a are inserted into the channels 40a.

The electronic calculator 12 is mounted on the stand in the manner shown in FIG. 7, so that the electronic calculator rests upon the inclined ledges or flanges 18a and b. Th e in clin ed position of the calculator makes it mucheasier to operate. Moreover, the visibility of the display on the calculator is greatly increased by mounting the calculator in an inclined position on the stand. The stand can be made at very low cost by molding or otherwise forming the various components of the stand from a suitable resinous plastic material, such as polyethylene, polypropylene, polystyrene or the like. Nevertheless, the stand is sturdy and highly serviceable. Thus, the stand will find widespread acceptance among users of electronic calculators and other similar devices.
