COMBINATION DOORCHECK AND DISPLAY Filed July 12, 1954 Patented May 28, 1935 UNI-TED?STATES 5 PATENT "OFFICE COMBINATION; 'DooRonEoK AND DISPLAY James w. Wyatt shaman. Pollard, Dallas, Tex., assignors to Screen Advertising, Incorporated, Dallas,' Tex.', a'corporation of Texas Application at 12,, 1934, Serial No. 734,762

" 'ZlClainis." (01. 40-60) V 7 frame, I mounta door check I2 including the This invention relates to new and useful improvements in combination door checks and dis;-

plays;

One object of the invention is to provide .an imadvertising matter, symbols, orthe" like.

An important object of the-invention is toin-gcorporate in an ordinary door check,-a display device which is positioned in view of persons passing through the door to-which the check is-applied, said display device being arranged to beswung each time the door is opened.-

.Another object of the invention is to incorporate tinan ordinary swinging door check, a display device which is preferably a sign and which is so arranged as to be capable of a limited swing-f ing. movement independently ofthe swing of the door check, whereby the reverse side of the sign after explained.

is exposed when the door isopened;

A further object of the inventionisto -incor'- porate; in an ordinary swinging door check, a display device which is arranged to be swung each time the door check is operated, whereby the attention of an observer is attracted to the indici'ai or advertising matter displayedonthe device.

, Still; another'object of the invention is to. pro'- vide an improved door check and display device, wherein the device is incorporated in the..ch'eck in such a way that it is unnecessary to change the general structure of said check, it being only necessary to add one moving, part on which said device-is mounted.

Aconstruction designed to carry out the inven-,, tion willbe hereinafter described; together with other features of the invention. V The invention will be more readily understood from a reading of the following specification and by reference to the a'ccompanying'drawing,in, which an example of theinvention is shown, and

wherein:

, Figure 1 is an elevation ofa doorhaving the combined door check and sign, constructed. in accordance with the invention, applied thereto, said 'door being in'a closed position, Figure 2 isa similar view, showing the doorin an open position, Figure 3 is a horizontal cross sectional view; takenon line 3--3 of Figure 1, Figure 4 is a view similarto Figure 3 and showingthe check swung to its outer position, and

Figure 5'is a vertical sectional view, taken on line:5-.,-5 of Figure 4.

In the drawing, the numeral I0 designates the frame of adoor and H the door proper. wOn the usual supportingbracket I3 which is fastened to the door frameby suitable wood screws I4. A

swinging member I5 comprising a pair of arcuate bars I6, disposed one above the other and securedtogether by a vertical tie pin I1, is pivotally mounted between the arms of the bracket on rivets I8. As shown in Figure 3, the member is pivoted oif center nearer the inner end of saidlmemher. I

A roller I 9 is mounted between the bars I6 at their extreme inner ends, and a larger roller 20 is secured between said bars at the outer ends thereof. .The rollers may be constructed of any suitable material but,are preferably composed of rubber, rubbercompound, or other shock absorb ing material. When the door II is in a closed position (Figure 3) the-roller?!) isarranged' to engage the stile-oi said door, as-will be herein:

A vertical crank shaft 2| is mounted to swing between the bars H5 at a point between the rivets I8 and the outer-ends or. said bars. I A coiled spring 22 has one iend secured to the offset portion of the crank shaft, and the other end fastened to an ear 23 on the rearof. the bracket I2. This spring is constantly under pressure.

In Figure 3,, the roller 20 on the outer end of the member l 5is engaging the door stile and the spring 22 is exertingits pressure to hold said door closed. It is; pointed out that said spring is off center of the pivot point of the member l5 and therefore its tension is holding the roller 28 against the door. The spring has also swung the crank shaf t 2| to the position shown in Figure 3.

When the door is opened, theroller 2D riding on the-door stile, causes the member I 5 to be swung. As the member swings the outer end of the spring 22 and the crankshaft to which it is fastened are. also swung. As soon as the spring 22 passes the pivot point of the member I5, it immediately exerts its pressure to pull the member I5 to its outer position, as shown in Figure 4. At the same time the crank shaft has been rotated to an off center position on the opposite side of itspivot and the spring also holds the crank shaft in thi off center position. (Figured) V It is pointed out that the distance fr'omthe rivets I 8 to the roller 20 is much greater than the distancebetween said rivets and roller I9. This causes the roller 2!],to travel in a larger arc than the roller I9 when the inemberis swung by the door. This variation in the arcs through which the rollers travel cause the roller 26. to swing out of the path. of the door when the door is opened. (Figure 4.) Since the roller 1 9 describes a smaller'arc, it swings in behind the door as said door opens and is, therefore, in the path of said door when the same is closed. The closing of the door causes the engagement of the back of said door with the roller I9, thereby swinging the member l back to the position shown in Figure 3. The return swing of the members swings the crank shaft 2| and spring 22 to its first position, said spring holding the door closed. Thus, it will be seen that the spring 22 holds the member in its two positions. The door merely swings the member to an off-center position, the spring tension completing the swing of said member. Due to the mounting of the crank shaft, said shaft is swung each time the member is operated.

The parts, thus far described; with the exception of the crank-shaft 2| are of the usual construction and are subject to variation. As has been described, the shaft 2| is arranged to swing and a display device or exhibitor 25'is fastened to the shaft and is arranged to be swung therewith, whereby each time the member I5 is swung the sign is swung to display its reverse side. Thus, with the door closed,'the front side of the device is displayed (Figure 1) and when the door is open, the reverse side is visible.

The sign includes a frame 26 having a display panel 21, carrying suitable indicia, mounted therein. The frame is provided with a pairof horizontally extending arms 28 which have their ends fastened to the upper and lower ends of the crank shaft 2| above and below the offset in said shaft. If desired, the arms 28 may be made integral with the crank shaft but this is not essential.

The arms 28 are secured in a position so that.

when the door check I2 is holding the door closed the sign is substantially parallel with the face of the door and is clearly visible to one entering the door. When the door is opened and the member 5 of the check is swung to the position shown in Figure 4, the sign, being secured to the crank shaft 2| is swung with said crank shaft and the weight of the swinging sign, together with the tension of the spring-22 on the shaft 2!, pulls said sign around so that itsreverse or opposite side is visible. The sign strikes thetie pin ii of i the member [5 to limit the swing in this direction, whereby the sign is'stopped in a position substantially parallel to the face of the door, thereby clearly displaying its reverseside (Figure 2). p

When the door is closedand the member I5 is returned to the position shown in Figure 3, the sign is again swung to its first position (Figure 3) due to the action of the crank shaft 2! and the spring 22. The movement of the sign is limited in this direction by the sign striking the curved edge of the bars 56. It is pointed out that'the weight of the sign as its swings around aids in rotating the crank arm to swing'it to its off center position, whereby a more positive action is assured.

The construction of the sign is immaterial as it may be a solid panel without theframe 26 and having the arms 28 made integral therewith. Also,'it would be possible to make the panel removable from the frame, whereby the sign or display could be readily changed.

' It is pointed out that the sign is at all times in a position substantially parallel to the face of the door, where it is clearly visible to the persons entering the door. Suitable advertising indicia may be displayed on the sign and a valuable advertising space is utilized. Further, both sides of the sign carry indicia, and regardless of whether the door is opened or closed, the sign is always in full view of the observer.

The description which has been given recites more or less detail of a particular embodiment of the invention, which is set forth as new and useful; however, we desire it understood that the invention is not limited to such exact details of 7 construction, because it is manifest that changes means for swinging the display independently of and concurrently with the member when the member is-swung by the opening or closing of the door.

2. A door check and display device for a swinging door comprising, a swinging member arranged tobe'swung by the opening and'closing of the door, a display having a swinging mounting on said member so as to eiipose opposite sides each time said member is swung by the door, means for swinging the display independently of and concurrently with the'member when the 'memher is swung by the opening or closing of the door,and meansfor limiting the movement of the display.
