FINISHING'PANEL MOUNTING MEANS Filed Dec. 11, 1941 INVENTOR 36 Ralph )MHafl Patented Dec. 21, 1943 FINISHING PANEL MOUNTING MEANS Ralph W. Hall, Cincinnati, Ohio, assignor to The Randall Company, Cincinnati, Ohio, a corporation of Ohio Application December 11, 1941, Serial No. 422,564

12 Claims.

This invention relates to the mounting of panels upon a supporting body to be covered or paneled.

The present application is a continuation in part, of my copending application filed May 31, 1940, hearing Serial No. 338,188, and entitled Welded ball panel fastener issued on March 10, 1942, as Patent No. 2,275,900 in Class 45/138F.

One of the objects of the invention is to provide a. simple and inexpensive though effective means for the mounting of panels for upholstering or decorative purposes, wherein provision is made for repeated removal and re-application of the panel, with a minimum of effort and time expenditure.

Another object of the invention is to provide panel mounting means of the character stated, which will securely and. snugly hold a panel against a frame or article to which it is applied, leaving no loose or unsightly joints at the contact area.

A further object is the provision of cooperative mounting elements upon a panel and a door, which elements are so constructed that a group of panels, or a group of doors, may be crated and shipped for assembly at a remote destination, without liability of becoming damaged to the extent of rendering them unfit for use. The mounting elements are extraordinarily undamageable.

Another object of the invention is to practicably simplify the manufacture of doors, panels and mounts of the general character herein referred to.

The foregoing and other objects are attained by the means described herein and disclosed in the accompanyingdrawing, in which:

Fig. 1 is a. cross-sectional view of a finishing or upholstery panel, having mounting elements incorporated in accordance with the present invention.

Fig. 2 is an end view of a support, in this case a vehicle door, parts being broken away to show mounting elements cooperative with those of Fig. 1.

Fig. 3 is a, fragmental cross-sectional view of the Fig. 1 panel mounted upon the door of Fig. 2.

Fig. 4 is a fragmental perspective view showing part of the door and its mounting element.

Fig. 5 is a fragmental perspective View of a panel binder strip including a modified form of mounting element.

Fig. 6 is an end view of a panel binder strip including a second modification.

The structure herein illustrated, while um doubtedly capable of other uses, has been found highly effective and desirable in the application of finishing panels to vehicle doors. One of the primary requirements of panel mounts for vehicle doors, is that they be capable of repeated removal and replacement by persons not particularly highly skilled in the refinements of upholstering practices. The panels accordingly are subject to considerable abuse in the attempt to remove and replace them, and for that reason must be constructed to withstand any form of treatment that might beresorted to by persons entertaining widely difierent ideas as to how the panels might best be removed. The most prev:- alent practice in removing panels, is that of prying them oif the door or support, using a screw-driver or. like, implement, whether or not the panel mounts admit of prying or straining in the demounting thereof. Since prying appears to be the prevailing expedient for the demounting of panels, the panel mounts of this invention have been especially designed to respond to pry ing forces, however ill-applied the prying forces might be. Moreover, the structure is designed for reapplication to the support, by the common expedient of hammering the panel into position. The panel upon replacement will be as securely mounted as it was when initially applied, under the teaching herein disclosed.

With reference to the accompanying drawing, the character I2 indicates a metallic vehicle door having an outer or front wall 13, and an inner or rear supporting back [4. The back may extend completely across the door as shown, or it may in some instances be cut away at its center portion so as to-leave a circumferentiating metallic flange boundingthe jamb portions l5 -l5 of the door. In either case, the means of the invention isapplicable, wherefore the nature of th door back is a matter of immateriality to the invention. The door back is to be of metal, or some material possessing the quality of flexibility, in order that tabs orears such as It and I! struck therefrom may be bent into and out of the plane of theback portion upon application of prying or hammering forces thereto. Fig, 2 shows the tabs or ears bent out of the plane of the back l4, whereas Fig. 3 shows them bent into coplanar relationship to the back.

As may best be understood from the Fig. 4 illustration, the back portion 14 of the door, or the panel supporting area thereof, has formed therein two substantially parallel cuts or slits,

bounded by the edges [8 and I9 between which the tabs or cars are located. Each tab or ear has three edges 29, 2! and 22, and a bend indicated at 23 which constitutes a rather stiff hinge. The opposed edges 28--2G of the tabs or cars are at all times spaced apart, that is, they do not meet when the tabs or ears are flattened or bent into the plane of the back M (see Fig. 3). Before application of a panel, the tabs or ears are disposed at an .angle to one another not substantially less than 90 degrees, and may preferably be at a somewhat greater angle to one another, in order to ensure their flexing to a substantially coplanar position when bent toward the back It by force applied against their edges 2 5-26 perpendicularly to the back [4.

The tabs or ears have their edges -40 :so I

spaced apart initially, as to freely receive between them the mounting element 24 carried by the finishing panel. As herein disclosed by way of example, the composite finishing panel may be constituted of a board 25, which may be of pressed paper .or composition material, bounded along its edges by a binder strip 25 which preferably is of metal. To themetallic binder strip is welded, or otherwise fixedly secured, the mounting element 24. In the preferred and most desirable construction, the mounting element 24 is spot-welded to one leg 2'! of the binder strip, this being a rapid and accurate operation as compared with other modes of fastening. The weld is at the point 28.

"The edges of the board or panel piece 25 are preferably embraced between the spaced parallel legs 21 and 29 of the panel binder strip, and may be held in place by frictional contact or other- .wise. A sheet 36 of fabric, leather, or other suitable covering material usually is applied to the panel and has its edges turned under the panel and against the leg 2! of the binder strip, as at 131, where it may contact the mounting element 2!.

In the preferred form of the invention, the mounting element 24 is a ball of steel or other suitable metal, fastened by rapid spot-welding method to the binder strip at 28. The ball at its great circle, or diameter, is slightly smaller than the space between the opposed edges 20-41} of the tabs or ears when the latter are disposed to one another at an angle not substantially less than a right angle. The length of the tabs or ears preferably should be such that when they are 'bent to the substantially coplanar relationship of Fig. 3, their edges 2!! will remain in contact with the ball at points intermediate the weld 2B and that diametral plane which is parallel to the ,panel or to the back H5. These contact points are clearly shown in Fig. '3, and it will be understccd that the connection so established will preclude rattle and vibration, and will main tain the panel tightly against the back M of the deer. The tightness of the joint thus formed holds the edges of the cover sheet 135 securely "in place.

To detach the panel from the door back, it :is necessary only to insert a prying implement into the 'joint at of Fig. 3, for lifting the panel and its attached mounting element24 away from the back M, whereupon the ears or lugs It and 'I'! will be bent outwardly to substantially the Fig. 1 position. To re-apply the panel, the ball 24 is to be inserted between the ears or tabs, and when the edges fifild thereof reach the binder strip,

a sharp blow directed against the outer face of the panel will cause the binder strip leg 2'! to perform as an anvil in bending the ears or tabs substantially to the coplanar position of Fig. 3. Under the impact of the blow, that portion of the fabric cover material 36 which is turned under the binder strip at the joint 32, will obviously be squashed or compressed to a negligible thickness, while the ears or tabs I6l I assume the substantially coplanar relationship, all as indicated by Fig. 3.

Whenever it may be necessary to do so, the ears or tabs may be angularly adjusted preparatory to application of a panel, by bending them slightly with the aid of hammer, pliers, or the prying tool used in detaching the panel.

In the Fig. 5 modification, the character I26 indicates the binder strip, to which is spot-welded or otherwise fixed the mounting element 33, which as shown may be in the form of a truncated cone. The mounting element 33 obviously will perform the function of the ball of Fig. 3 in holding the panel to the support area it.

In the modification of Fig. 6, the mounting element is shown as a rivet or the like having a head 34 and a reduced shank 35 against which the ears or tabs may impinge for holding the panel in place. While the mounting element t l-5 is here represented as being attached to the mounting strip 226 by peening its end at '35, it should be understood that welding or other means of fastening might be employed.

It will of course, be apparent that the several modifications herein disclosed are suggestive of other and equivalent structures that may be used in practicing the teaching of this disclosure, many variations being possible in the shape of the mounting element carried by the panel.

Attention should be directed to the fact that the performance of the mounting means of the invention does not in any manner depend upon resiliency or springiness of any parts. The use of special materials and additional manufacturing operations, is thereby avoided. As will be understood, the ears or tabs may be formed in the same press operation that forms the back and jamb of the door. The attaching of the spherical mounting elements to the binder strips is an automatic continuous spot-welding operation performed by machine.
