Abstract
A sign holder having two identical support members, one in a lower position and one in an upper position. Pockets in the support members hold the edges of a sign, and extendable arms telescoping from each end of the support members have curved ends for engaging the edges of a vehicle door. Each arm is fastened to the inside surface of the door edge with a set screw. Door-abutting faces of each arm are lined with soft material, and door-adjacent faces of the support members have rubber nubs attached thereto so that the door's finish will not be scratched or marred.

Description
Technical Field
The present invention relates generally to sign holders which are removably attached to vehicle doors.
Background Art
Vehicle door-mounted sign holders have long been known in the prior art. But, such prior art devices still suffer several problems.
One major problem is that prior art sign holders may be removed from the vehicle without having to open the door. This is a particular problem for those who have expensive signs displayed on their vehicles, and therefore do not want them easily removed by a passer-by, yet wish to have the signs easily transferable to other vehicles.
Those sign holders which will adjust to various sizes of vehicle doors are burdened with many small parts which must be moved or adjusted, and thereby increase the likelihood of mechanical faults or failure. The cost of maintaining a device with many moving parts would also be inherently greater than one with few total parts and fewer still which move.
Another problem, related to devices which have their adjustment mechanisms located on the outside of a vehicle door, is the effect of weather on those parts which must be adjusted. Dirt and corrosion can quickly make it difficult or impossible to turn adjustment screws or adjust other small moving parts--a problem which increases with a larger number of moving parts.
Disclosure of the Invention
It is therefore a general object of the present invention to provide an improved vehicle door-mounted sign holder.
Another object is to provide a sign holder which is easily removed and adjusted to various sizes of vehicle doors.
A further object of the present invention is to provide a sign holder which may not be removed without first opening the door to which it is mounted.
More generally, it is an object of the instant invention to provide a sign holder having upper and lower support members which border the edges of a sign, and telescoping connector arms having a portion affixed to the ends of each support member, for grasping the edges of a vehicle door. The grasping portion of each arm is fastened to the inside surface of the door edge with a set screw, and the door-abutting portions of the arms are lined with soft material to avoid scratches and marring. The support members are held spaced away from the door's face using small rubber nubs affixed to the members.
These and other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

Best Modes for Carrying Out the Invention
Referring now to the drawings, in which identical or corresponding parts are indicated by the same reference character throughout the several views, and more particularly to FIG. 1, the sign holder device is designated generally at 10, and is fastened to a vehicle door 11.
Referring now to FIGS. 1 through 4, sign holder 10 includes two identical horizontal support members 12, each having a pocket portion 13. One member 12, is located near the bottom of the door, and has its pocket portion 13 directed upwards. The other member 12 is located near the top of the door and has its pocket portion 13 directed downwards.
Each support member 12 has a telescoping connector arm 14 attached at each end. Each telescoping connector arm 14 includes a slidable arm portion 14a and an affixed sleeve portion 14b. In the described embodiments of the invention the affixed portions 14b of telescoping connector arms 14 are connected end to end to form a single elongated sleeve portion 14b equal in length to support member 12. This elongated sleeve 14b is longitudinally slotted and affixed to a side of support member 12.
As seen in FIG. 4, pocket portion 13 has a cross-section in the shape of a "U", and slotted sleeve portion 14b has a cross-section in the shape of a "C", the back of sleeve portion 14b and a wall of pocket portion 13 being a common element between the two. As seen on FIG. 3, a sign 16 inserted in pocket portion 13 cannot slide out of the ends thereof. Thus, in use, a sign 16 will be held between upper and lower support members 12 within their respective pocket portions 13.
Arm portion 14a is slidably inserted within the end of each sleeve portion 14b. Each slidable arm portion 14a has an inwardly curving end 17 bent parallel to the main body of slidable arm 14a so as to grasp the peripheral edge 11a of door 11. A layer of soft material 18 lines the door-abutting portion of arm 14a to prevent the finish at the edge of door 11 from being scratched or marred. Curved end 17 is punched and tapped to receive a threaded set screw 19, which is tightened against the inside surface of door edge 11a to fasten arm 14a to door 11.
A wedge-shaped portion 14c of arm 14a is located abutting the outside face of door edge 11a proximal curved end 17 with the thicker portion thereof distal curved end 17, and serves to hold the main body of arm 14a from door 11.
Rubber nubs 21 are affixed to the door-adjacent face of support members 12, and serve to protect the door's finish from being scratched or marred. By spacing support member 12 away from door 11 the chance of non-uniform fading of the paint behind support members 12 is reduced, since direct sunlight reaches points behind support members 12.
Thus, it may be seen that telescoping connector arms 14 affixed to support members 12, may be adjusted to properly accommodate various sizes of vehicle doors. The width and thickness of arm 14a is such that sleeve portion 14b must expand slightly as arm 14a is inserted therewithin. Thus, sleeve portion 14b will tend to clamp on arm 14a and be held in place.
Each arm 14a is flexed slightly in order that bent portion 17 may grasp an edge of door 11a. This flexing will in turn cause sleeve portion 14b to crimp slightly upon arm 14a, thereby producing an additional "grip" on arm 14a. As set screws 19 are threaded inwardly, curved end 17 of arm 14a will clamp upon door edge 11a and temporarily fasten arm 14a in position.
In order to make device 10 unremovable from door 11 without first opening door 11, the total length of support member 12 (including the affixed portions 14b of telescoping connector arms 14) and either of its slidable arm portions 14a, must be greater than the width of door 11. Thus, the only way to remove a support member 12 from door 11 is to unfasten slidable arm portion 14a from the edge of door 11 and extend it outwards--and this can only be accomplished while door 11 is open.
Once a support member 12 is fastened in place as described above, near the bottom of the door, the lower edge of a sign 16 is inserted in pocket portion 13 thereof. Then the other support member 12 is positioned with its pocket portion 13 directed downwards, on top of sign 16 and secured in place in a similar fashion.
It can be seen that sign 16 cannot be removed from sign holder 10 so long as door 11 is closed. Also, since sign 16 and support members 12 are spaced away from the surface of door 11, no scratching or marring can occur.
Referring now to FIG. 5, another embodiment of the invention utilizes a support member 112 with affixed portions 114b of telescoping connector arms 114 attached thereto adjacent door 11. It should be noted that FIG. 1 also shows the second embodiment of the invention, as it would look the same in that view.
Since the amount that slidable arm 114a is flexed between affixed portion 114b and curved end 117 is less in this second embodiment, an aperture 122 is punched and tapped in each end 112b of support member 112 (this area could also be considered part of the affixed portion 114b) perpendicular to the longitudinal axis thereof. A threaded set screw 123 is inserted within aperture 122 and tightened against slidable arm 114a in affixed portion 114b.
It will be readily understood that the particular disposition or arrangement or nature of the elements of the invention are not of the essence of the invention, and that many variations, substitutions, and modifications may be made, in departure from the particular construction and characterization in the drawings and foregoing description, without departing from the true spirit of the invention. It is therefore to be understood that the invention should be limited only by the breadth and scope of the appended claims.
