KAMBORIANJR ATTORNEY United States Patent "ice 3,112,563 METHDD 0F INSERTING A ROD INTQ A PLATE Jacob S. Kambonian, 133 Forest Ave, Newton, Mass., and Jacob S. Kamhorian, In, 49 Fay Lane, Needham Heights 94, Mass.

Filed .lan. 3, 1961, Ser. No. 85,176 12 Claims. (Cl. 29-432) An object of this invention is to provide a new and unique method of inserting a rod in a plate, and more specifically to insert a nail into the margin of a decorative panel similar to that shown in Patent No. 2,576,121 so that the panel may be secured to an automobile door frame by means of the nail.

A further object is to secure a rod in a plate in a simple, effective manner so that the rod will project outwardly of one surface of the plate with the head embedded in the interior of the plate.

Other objects will become apparent upon a perusal of the following description and drawings.

In a preferred embodiment of the invention the plate takes the form'of a backing made of heavy paperboard or the like having a flexible covering material covering one face of the backing folded over the sides of the backing, and having a margin extending inwardly of the sides to cover a portion of the other face of the panel adjacent the sides. The rod takes the form of a headed nail that it is desired to insert through the margin and into the backing with the head embedded in the backing and the nail shank projecting outwardly of the margin. The nail is then used to connect the panel to an automobile door frame.

The nail which has a cutting surface on the periphery of the head, is inserted m the panel by placing its shank in the jaws of a rotatable tool, rotating the nail about its axis and moving the panel in such a path that the cutting surface intersects the margin of the covering material, cuts its way through the margin and is moved into the backing in a curved path so that the nail head and nail shank cut an undercut slot through the margin and into the backing. At the end of the cutting operation, the nail is released from the tool, and the nail head lies embedded in the backing at the end of the slot with the shank projecting outwardly of the margin. At this time, thermoplastic adhesive may be extruded into the undercut slot and allowed to solidify. The solid adhesive acts as a filler and prevents retraction of 'the nail through the slot as well as firmly anchoring the nail in the panel.

Reference is now made to the accompanying drawing wherein:

FIG. 1 is a side elevation of an automobile door on which a decorative panel made in accordance with the invention is mounted;

FIG. 2 is a side elevation of a panel prior to the insertion of the nails therein;

FIG. 3 is a perspective view partially in section of a portion of the panel with the nails inserted therein;

FIG. 4 is a view partly in section taken along the line 44 of PEG. 3;

FIG. 5 is a view partly in section taken along the line 55 of FIG. 3;

FIG. 6 is a view illustrating the way in which the nail is inserted in the panel;

PEG. 7 is a view partly in section showing the connection between the panel and the automobile door; and

FIG. 8 is a perspective view to an enlarged scale of a nail used in practicing the invention.

Referring to FIG. 1, 10 indicates the door of an automobile viewed from the inside. The door is of conventional type having a rigid frame 12, a window open- 3,112,563 Patented Dec. 3, 1963 ing 14 in the upper part of the frame, and an ornamental finish panel 16 secured to the lower part of the frame. As illustrated, the contour of the panel is such as to conform more or less to the contour of that part of the door in which it is installed. The panel comprises a backing 18 of stiff sheet material such as heavy paperboard, and a covering 20. The covering completely covers the face 21 of the backing that is to face the interior of the automobile, is folded around the edges of the panel and has a margin 22 extending from the edges inwardly of the other face 23 of the panel. The margin may be pulled about the panel edges and adhesively bonded to the panel face 23 by mechanism similar to that shown in Patent No. 2,576,121 and pending application Serial No. 31,570 filed May 25, 1960.

The door frame 12 is provided with ofisets 24 (see FIG. 7) having elongate openings that receive bushings 25 usually made of nylon. The bushings have elongate recesses 28 that receive nails 30 secured to the panel to thereby provide a connection between the door frame and the panel. The instant invention provides for a method of inserting the nails in the panel.

Each nail 30 has a shank 32 of relatively small diameter and a head 34 at one end of the shank of relatively large diameter. The peripheral edge of the head may be serrated to provide cutting teeth thereon for the reasons set forth below. The peripheral portions of the head furthermost from the axis of the shank lie on a circle whose center of curvature coincides with the axis of the shank, and the cutting teeth lie on said peripheral portions.

Because of the location of the offsets 24 and bushings 26 in the door frame, it is desirable to have the nail shanks extend through the margins 22 of the covering 29 at the points indicated by the letters x in FIG. 2. To insert a nail in the panel, the shank of the nail is inserted in the rotatable jaws 35 of a gripping tool 36. The tool 36 may take the form of any conventional implement having means for rotating the jaws such as a drill. The jaws are then rotated to cause the nail to rotate about its axis. The panel 'is then manipulated from the solid line position in FIG. 6 to the dotted line position. This causes the rotating nail head to intersect the margin 22, cut its way through the margin and move in a curved path into the backing 18. The relative path of movement of the nail and panel causes the nail head to have a component of movement parallel to the face 23 and the margin 20 through which the shank projects and terminate its movement approximately midway between the faces 21 and 23 of the panel. The portion of the nail shank that intersects the margin 22 and backing 18 cuts or tears its way through the material. The serrated peripheral edge of the nailhead helps it cut its way into the margin and backing.

When the nail has reached the desired position in the panel the manipulation of the panel and the rotation of the nail is terminated and the nail is released from the jaws 35. The nail head and shank will have cut an undercut slot 38 through the margin and into the backing, and there will be a portion of the backing located between the nailhead and the backing faces '21 and 23 (see FIG. 4) which resists outward displacement of the nail through the backing faces and renders the nail invisible from the side of the panel that will face the. interior of the automobile. In order to prevent backtracking of the nail through the slot 38 and, to firmly embed the nail in the backing, a filler material maybe inserted into the slot. This filler material may take the form of thermoplastic adhesive 40 (FIG. 7) that is extruded in liquid form into the slot from a nozzle 42. The adhesive tends to infiltrate about the nail head and shank and fill 3 the groove, and upon solidifying not only prevents retraction of the nail through the slot 38, but also firmly anchors the nail in the backing.

After'the nails have been inserted in the panel by the above described process, the panel and door frame are juxtaposed so that the nails 30 and bushings 26 are in alignment. The offsets 24 or bushings 26 are then pressed toward the panel to anchor the nails in the bushing recesses 28 to thereby secure the panel to the door frame.

While the instant invention has been disclosed as being used to insert 'a nail in a panel that is subsequently to be secured to a door frame, it obviously has utility in other environments. For example, it may be used to insert a spike ,in the sole of a golf shoe or insert nails to wall board panels to enable the panels to be secured to the studding in a house.

While one desirable embodiment of the invention has herein been shown and described by way of example, itis to be understood that the invention is broadly inclusive of any and all modifications falling within the scope of the appended claims.
