Unitecl States Patent() DISPLAY DEVICE Fon AN ADVERTISING CARD, on THE LIKE,
Franklin W.v Alters, Jr., Huntington, W. Va. Application August 20, 1953, SerialVNo. 375,386
2 Claims. (CL 40s-11.7)
This invention relates to a display device and more particularly to a device for displaying an advertising card or the like.
It is the general object of this, invention to produce a new and improved display device of the character described.
It is a more specific object ofthe invention to. produce a display device into which an advertising card or the like may easily be inserted together with means for preventing withdrawal of the. card either Vaccidentally or by unauthorized persons.
A further object of the invention is to produce a display device ofthe character described in the. preceding paragraph which is particularly adaptable to be clamped to a post, such as a post mounted parking meter,- so as to display advertising matter.
Still another object of the invention is to provide a display device which includes a base member having an exposed face portion provided along each side thereof with guideways for receiving and retaining an advertising card, with one of the guideways being spaced from the face portion to provide an entrance slot through which the card may be inserted together with retaining means for retaining the card in position until released by keyoperated means.
A further object of the invention is to produce a display device of the type described in the preceding paragraph in which said retaining means are spring-operated and provided with a cam portion to be contacted by the leading edge of a card inserted through the slot so as to move the retaining means lout of `a position blocking the slot to permit ready and easy insertion of a card into the guideways, with the spring means serving to move the retaining means to blocking position when the card is sufciently inserted.
Other and further objects and advantages of the invention will be readily apparent from the following description 'and drawings, in which:
Fig. l is an isometric view of a display device embodying the invention;
Fig. 2 is an enlarged front elevational View partially broken away of the device shown in Fig. l;
Fig. 3 is a horizontal sectional view along line 3--3 of Fig. 2;
Fig. 4 is a horizontal sectional view along line 4 4 of Fig. 2; and
Fig. 5 is a vertical section along line 5-5 of Fig. 2.
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail one specific ernbodiment, with the understanding that the present disclosure is to be considered as an exemplication of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointedv out in the appended claims.
Referring now to the drawings, there is shown a display device comprising 'a base member, generally indirce cated at 10, includingv two similarly formed base portions 12 and 12a. As the base portions are substantially identical, similar reference numerals will be given to similar parts on each base portion, with those relating to the base portion 12a carrying the designating letter 11.
Each base portion is providedl with a semi-cylindrical groove 13, 13a extending from end to end thereof, and means in the form of bolts 14 are provided for securing the base portions. together so as to clamp the device around a post 154 which may be the post on which a parking meter is mounted. Each base portion is provided with an exposed, substantially rectangular face portion 20 and 20a andk mounted on each side of each face portion are guideways 21, 22, 23 and 2li. Each guideway is provided with a portion 25 overlying but spaced from the face portion and secured thereto by the screws 26. The lower guideway 24 is spaced from the adjacent surface of the face portion 20 so as to provide an entrance slot 27 through which a card 28 may be inserted, with the inserted card being positioned beneath the orverlying` portions 25 of the guideways.
Retaining means, generally designated Sil, are provided for retaining an inserted card in position on the face portion, with the retaining means comprising a generally U-shaped leaf spring 3l having a leg portion 32 located in. a recess 33 formed. in the. base member and the opposite. leg 34 positioned in the slot 27'. The end of the leg 34 isv inturned to. form a lip. 35 normally blocking the slot so. as to. prevent the card from falling out of the guideways.. It will be noted that the leg portion 34 is slanted and thus provides a cam surface `aligned with the slot 27 so that when a card is inserted into the entrance slot, the leading edge of the card contacts the cam-like surface of the leg 34 so 'as to depress the spring and thus y move the lip 35 out of blocking position in the slot.
The card then may easily be inserted so as to lie beneath the guideway portions 25, and when the lower edge of the card passes beyond the lip portion 35, the latter is urged outwardly into blocking position relative to the slot by the spring. From the foregoing it can be seen that the insertion of a card in the display device is eX- tremely simple, it only being necessary to insert the card in the slot and move it upwardly in the guideways to a position where its lower edge passes beyond the lip portions 35 and 35a.
One of the diiculties heretofore encountered in display devices of the general nature herein shown is that unauthorized persons, particularly juveniles, are wont to tamper with the advertising material, particularly to withdraw the card or other advertising matter. Thus, if exposed or easily operated means are provided for retaining the card in position, loss of the advertising material is apt to result soon after it is installed.
For this reason the display device of the present invention incorporates the use of key-operated means for withdrawing the display card.
For this purpose a pair of openings 36 are provided in the lower guiding means 24 aligned with the legs 34 of the springs 31, and there is provided a key 37 having a pair of pins 38 thereon which may be inserted in the openings 36 to contact the leg portions 34 and thus to move the lip portions 35 to unblocking position relative to the slot 27. With the retaining means so moved by the key, the card may be moved downwardly until it has passed the lip portions whereupon the key may be withdrawn and the card slipped out of the slot.
The provision of the pair of openings 36 rather than a single opening makes it more ditlcult for unauthorized persons to remove an advertising card. If only one hole were used anyone with a match, nail or similar object could remove the card, using one hand to hold the nail or other object and the other hand to remove the card.
By using two holes both hands would be occupied in moving the springs to unlocking position, leaving no hands free to withdraw the card.
Obviously the entire housing may be secured to the parking meter post in the position shown or in inverted position if it is preferable to insert the cards from the top.
From the foregoing it can be seen that there has been provided a display device which is particularly adapted to be readily secured to a post and which is provided with means for displaying a card of advertising matter and the like, and that the card, while readily inserted in the device, may not oe withdrawn therefrom except by the use of a key in the manner described. As so constructed the display device is particularly adapted for use in conjunction with parking meters wherein the danger of vandalism is particularly acute as the display device is within the reach of children of almost all ages.
