s claims. (ci. 40-16) acter is furnished, which may function as a departmental guide -.and be employed for the display of 'various information, such as prices, classitications oftmerchandise in a given area, specials, etc. The `apjgnaratus will provide for "two-way viewing, may be adjusted to display inlformation to maximum advantage, and will readily permit of ythe changing of the `display from day to-day or other* wise.
Still another object is that of providing for a display device which may be ampli'ed for diminished, and in which the several components will, in effect, be rigid with each other, so that undesired relative movement of the parts is avoided.
Still 'another object of the invention is that of designing an assembly Aof this type which will include relatively few parts, each simple and rugged in construction and capable Aof pnoduction by quantity-manufacturing methods; such parts cooperating over long periods of time with freedom from all diiiiculties and being capable of ready manipulation by unskilled help.
With these and other objects in mind, reference is had to the attached sheet of drawings illustrating one practical embodiment of the invention, and in which:
Fig. l is ya fragmentary partly sectional face view of a display device;
Fig. 2 is a fragmentary enlarged sectional side view of certain of the components of that device;
Fig. 3 is a transverse sectional View taken along the line 3-3 in the direction of the arrows as indicated in Fig. 2;
Fig. 4 is a sectional plan view taken along the line 4-4 in the direction of the arrows as also indicated in Fig. 2; and
Fig. 5 is .a fragmentary perspective View of a pair of the separated elements ofthe device.
Referring primarily to Fig. l, the numeral indicates a post or supporting member which will preferably be hollow to receive in telescopic relationship a rod. The latter, by means of a suitable clamp 11, may be retained at any desired elevation. Secured to the lower end of post 10 is a suitable base (not shown), by means of which the device may be supported in a stable manner. To the upper end of the rod a frame 12 is attached. That frame, in a manner similar Vto frames hereinafter described, will preferably include a channel and conveniently be of rectangular conguration. One end of the channel is interrupted by a slot 13. Through the latter a card 14 may be introduced into or removed from the frame.
The card may indicate, for example, a given price range of merchandise, the number of a section under which that merchandise is displayed, the type of merchandise so displayed, etc. The space within the frame 12 will be ICC such that preferably two cards may be `accommodated therein. This will permit of a single assembly, embracing certain main indicia within frame 12 when approached `from one direction and a `different indicia or designation when `approached from an opposite direction. Of course, the `same notice or information may appear on both card-s, but by this construction it will not be necessary to furnish double-faced cards with unnecessary duplication and eX- pense being involved.
Fra-me 12 will serve -as a support or additional frames which may be subsidiary thereto. According vto thefheight to which frame 12 is adjusted, a. larger or snrallernumber of these subsidiary frames may be employed. In co'mmon with frame 12, these frames 15 will involve channel `members as especially shown in Figs. 2,73 and 4. These members will present, between their arms 1'6, suicient space that a pair of card-s 17 may be supported therein to have their faces exposed through the sides of the frames. in accordance with `the present teachings, it is intended that these subsidiary frames be substantially rigid with frame 12. ln other words, they will not have free movement with respect thereto.
To achieve this result, and iat the same 'time permit of a series of subsidiary frames being coupled to each other and to the main frame 12, a connecting structure, such as is herein illustrated, is preferably employed. That structure wiil include rivets `embracing a body 18, a reduced Vshank or stem 19 Eand an enlarged head 20. A pair of these rivets are aiiixed preferably to the upper edges of frames 15 by having their Vlower portions pass through openings in the `base of the upper channel and thereupon being headed, as indicated at 21. lt is to be noted that these fastening elements are secured to the frame in a zone adjacent one of its ends, which will be its inner end. `By this, there is meant that end which lies most closely adjacent post 10. Asillustra'ted in Fig. l, the rivets of the several frames '.15 will. all be within a zone short of the adjacent side edge of frame 12.
The base portions of the channel members at zones opposite those in which the rivets 21 are disposed are formed with openings. These openings, as especially illustrated in Figs. 2, 4 and 5, have keyhole conligurations, as indicated at 22. The enlarged parts of these openings have areas such that the heads 20 of the rivets may readily pass therethrough. The reduced shank portions 19 of these rivets will be accommodated wit-hin the lmore restricted portions of the openings. The spacing of head 20 from body 1S should be barely in excess of the base thickness of the frames. In addition to having openings of this character formed in frames 15 in line with the rivets of those frames, similar openings are formed in the face of frame 12 to one sid-e of post 10.
Thus, in use, it will be appreciated that by simply passing the rivets of one frame through the openings 22 formed in frame 12 land then moving the frames with respect to each other in the same plane, the heads 2i) of the rivets will overlie the more reduced portions of the slots or openings 22. This will prevent separation of an upper frame 15 from frame 12. Due to the coupling of the parts this connection will, in eiiect, make that frame 15 a unit fixed with respect to frame 12. In other words, no accidental swinging movements will occur.
Under usual practice, a second frame will be coupled to frame 12 to the opposite side of post 10, from which the initial frame 15 has been disposed. Further subsidiary frames-.according to the desire of the user-arq in turn, coupled below the iirst pair of frames and this coupling may be continued until, for example, twenty subsidiary fram-es are grouped below frame 12. Under these circumstances, the height of the latter will, of course, have been properly adjusted. All of these subsidiary frames will be, in eiect, rigid with the main frame. Cards such .as 17 or 14 associated with the frames will ride in contact with portions of rivets associated with `an adjacent frame. In this manner, minimum friction will be encountered in inserting orremoving a card, especially if the latter be formed of a smooth plastic. l
From the foregoing, it will be understood that among others, the sevenal objects of the invention as specically aforenoted are achieved. Obviously7 numerous changes in construction may be resorted to `and the steps of the method may also be varied without departing'from the -spiri't of the invention as dened by the claims.
l. In a display device a frame consisting of a channel member the base portion of which forms the periphery vof said frame; a post attached to said base portion and extending outwardly from said frame, an enlarged head portion at the outer end of said post, the latter having a length which is barely in excess of the thickness of the base portion of said channel member; said base having `formed therein a keyhole slot with its enlarged opening of such diameter that the head portion of a headed post attached to a like frame can be inserted therein, and the diameter of its restricted portion is such that the stem of a post attached to a like frame can be snugly positioned therein.
2. In a display device a frame consisting of a channel member the base portion of which forms the periphery of said frame; a post attached to said base portion and extending outwardly from said frame, a second post attached to said base portion in spaced relation with said first post and also extending outwardly from said frame, enlarged head portions attached .to said first and second posts at a distance from said frame which allows the lengths of the posts to be barely in excess of the thickness of the base portion of said channel member; said base having formed therein a keyhole slot with its enlarged opening of such diameter that the enlarged head portion of a post attached to a like frame can be inserted therein, and the diameter of its restricted portion is such that a post attached to a like frame can be snugly positioned therein and a second keyhole slot formed in the base portion of said channel member in spaced relation with said rst keyhole slot whereby a second post of a like frame can be positioned therein.
