7 Claims.. (01. 40-102) s This. invention relates to a visible reference desk stand and morev particularly to a stand wherein a, plurality of leaves carrying visible reference data may be supported on a desk or the like in a convenient viewing position.

It is an object of the invention to provide a stand as above outlined which is susceptible of use in either one of" two alternative positions. In. one position the leaves are held at an acute angle to the vertical, and in the other position the leaves. are held at an acute angle to the horizontal. One position is preferable in some instances, while in other instances the other positionis preferred and it is therefore among the objects of the invention to provide a device which can be used without modification in either of the two positions mentioned.

In connection withthe mounting of the leaves which carry the reference data it is another object of the invention to provide a novel pintle mounting bracket whichpermits the removal of leaves and. their replacement; with a minimum ofdifliculty, andwhich atthe same time is simple inconstruction and substantially foolproof.

These and other objects of the. invention which will be. set forth in greater detail hereinafter or whiohwill. be apparent to one skilled in the art upon reading these specifications we accomplish by that certain construction and arrangement of. parts of which we shall now describe an exemplary. embodiment.

Reference is. made to the. drawings forming a part. hereof and in which:

Figure 1 is a plan view of a device according to our invention.

Figure-2' is a front elevational" view of the same.

Figure 3 is a cross sectional View taken on the line 3-3 of Figure 2.

Figure 4 is a cross sectional view of the same taken on the line 4-4 of Figure 2.

Figure 5-is a detailed fragmentary cross sectional view on an enlarged scale taken on the line 55 of Figure 2-, showing the pintle mounting bracket in its normal condition.

Figure 6 is a view similar to Figure Sbut showing the pintle mounting bracket in the course of removal of a leaf.

Figure- 7 is a perspective view ofa piece of sponge rubber and a contact plate used in the device.

Briefly, in the practice of our invention we providea frame having at its opposite ends pintle engaging members so that the leaves may be mounted on the frame between these pintle mountingelements. The frame and a support for the frame are mounted on a base. in the manner" of an easel with the support and frame secured. together at their tops and secured respectively. to the base in spaced relation forming. aeuter angles with the vertical on either side thereof. The base is providedwith footmembers: to.sup=- port. the. device in its vertical position and the support and the rear sideof the base are pro-- vided with other foot members. to support thede vice in a more or less horizontal position.

Referring now more particularly to-the drawings, we have shown a frame member generally at ID, to whichare secured the pintle engaging: members indicated generally at H and I2. These. members will be described in more detail hereinaften.

The frame I0 is provided with the sidemembers I3 and I4 extending forwardly at. an angle: to the plane of the member I ll. The entire structure, including the members l0, I3 and III, is tilted rearwardly slightly as best seen inFigure: 3 and the angular relationship'between the members I0, [3 and I4 is best seen. in Figure 4. Asupport isindicated at I-5- and is in the natureof a prop which may be spot welded or otherwise suit. ably secured to the back of the member Hl ad:- jacent its upper end. The assembly of the members I0, I3 and I4 (which may of course and preferably will be formed from a single sheet: of material) is secured to a base member I16, as by means. of spot welds securing the flanges I30; and Ila. to the base member I6 as best seen in Figured. The support or prop I5 is suitably secured to the base I6 as by spot welding at I511; The base I5 may be provided with lateral u-pwardly extending flanges Ita and with the down-- wardly extending front and rear flanges Hib and I60. The flanges I61) and I are inturned'at their free ends as indicated at Hid and IIie, and rubber foot members or the like are secured" thereto as indicated at IT. When the device is' standing on the foot members IT, as; seen in Fig-- ure 3, the leaves are supporte'd'at an acuteuangle. to the vertical so as to be conveniently positioned. for examination by an operator seated at a desk. upon which the stand is disposed.

- The flange IE0 is providedv with footmembers I8-simil'ar to the footmembers I"! and a foot member I9 is provided at the upper ends of the. support I5. Thus the stand, may be placed upon a surface as indicated in broken lines at 20 resting upon the foot members I8 and. I9. so that the. leaves will be held at an acute. angle. to. the horizontal in a position convenient for examination by a standing person. The effect may be visualized by rotating Figure 3 approximately 90 in a clockwise direction and considering the broken line 20 as the surface of a desk or the like.

The side members or wing members I3 and (4 will preferably be provided with the bumper button indicated at 21 in order to protect the leaves when they are resting against the members 13 and M.

Coming now to a more detailed description of the mounting of the leaves it will be understood that the leaves are of conventional construction and are provided with the pintles 22. These pintles may be identical at the opposite ends of the device and are provided with the collars 23. The pintle mounting bracket H is simply a piece of angle metal suitably spot welded or otherwise secured to the frame It and having in its free limb a series of pintle engaging holes 24. The upper pintle mounting bracket which has been generally indicated at i2 is shown in detail in Figures 5 and 6. As can be seen from these figures it comprises a channel member 25 and a box-like member 25 which has a portion fitting into the channel 25. For the sake f appearance an offset has been provided in the member 26 as at 2501 so that the appearance of the bracket is improved. The bottom surface of the box-like member 26 is open or slotted as indicated at 2'! in substantial alignment of pintle engaging apertures 28 in the trans- I verse web of the channel 25. The slot or opening 21 is closed by a contact plate 29 on top of which is placed a block of sponge rubber or other suitable resilient material iiii. ihe block 3%) is held in place by an additional channel member 3! in reverse position which is disposed between the transverse web 25b of the box-like element 26 and the block 36. The channel 25 is spot welded to the frame or panel 19, and the box-like member 26 is held in place by sheet metal screws or the like at 32. The channel member 3| has its rear flange notched to clear the screws 32 and is simply held in position by the various members.

The position of the parts in Figure 5 is the normal position with the leaves in place. If it is desired to remove a leaf so that reference data may be brought up to date or changed, the entire leaf is lifted upwardly with the pintle 22 bearing against the contact plate 29 and compressing the block 30 as seen in Figure 6. In the position of Figure 6 the lower pintle 22 will have cleared the bracket H and the leaf may be readily removed from the stand. In reinserting the leaf the upper pintle 22 is first inserted in its proper aperture and then upward pressure is exerted to compress the block 30 until the lower pintle can be inserted into its appropriate pintle engaging aperture in the bracket I I.

The compressibility of the material 30 is such that accidental displacement of the leaves is avoided and yet the material is soft enough so that if it is deliberately desired to remove a leaf it can be done without the exertion of great strength. It will be observed that the box-like structure 25 covers the spacing channel 31 and also covers the screw 32 so that the appearance of the device is neat, as best seen in Figures 1 and 2.

It will be understood that numerous modifications may be made without departing from the spirit of our invention. We therefore do not intend to limit ourselves in any way other than as specifically set forth in the claims which follow.

Having now fully described our invention what we claim as new and desire to secure by Letters Patent is:
