4 Claims. (Cl. 312-7) This invention relates to a spring fastener adapted to secure a planar object in association with a wall surface. More especially, the invention comprehends a wall surface with which a planar object is adapted to be fixedly associated by a clip of novel construction, the clip being adapted to be anchored to a protruding member on the wall surface by extension around a portion of the member and being adapted to concurrently bias the planar object toward the wall surface adequately for the association.

The fastener of this invention is particularly adapted to secure a built-in antenna in the upper portion of a plastic cabinet.

Previously the antenna bearing plate was attached to the cabinet of a plastic television receiver by support members extending downward from the top of the cabinet. The support members were hook-shaped in vertical section and included lateral end portions, extending toward each other, on which the antenna plate rested, the support members usually being integral parts of the cabinet. This method of support was found to be inadequate for mass production methods. For'one thing, it was difficult to maintain desired dimensions and owing to this,

the antenna plate either too often failed to go between the,

support members or was so loose that it did not stay on its supports and dropped down on the tube. This was hazardous when a metal backed picture tube was in operation below the antenna due to the possibility of shock to the operator of the receiving set when he tried to adjust the antenna. Furthermore, the antenna was often objec tionably loose in its supports.

Due to the present invention, the foregoing disadvantages have been overcome since the clip operates to constantly hold the planar object toward one of the walls of the cabinet and fixedly associate the object therewith. Additionally, the clip is simple, inexpensive, easy to manufacture and readily applied by production line workers.

For a further and better understanding of the invention besides one manner of carrying it out, reference may be had to the accompanying drawing in which:

Fig. l is a fragmentary view, in perspective, of the upper left corner of the cabinet indicated in Fig. 4, the back thereof having been removed to show the novel features;

Fig. 2 is a view corresponding to Fig. 1, the parts being shown in elevation and one of the same in a different positlon;

Fig. 3 is a view corresponding to the Fig. 2 view to show an additional function of the fastener;

' Fig. 4 is a horizontal section of the cabinet shown in Fig. 3, as viewed from below the level of the fasteners and showing the back attached to the cabinet; and

Fig. 5 is a view corresponding to Fig. 3 showing a second embodiment of the invention.

In the drawings, the reference character 6 is used to denote a one-part cabinet in its entirety. It is of some suitable plastic material such as Bakelite. The cabinet includes a top wall 7 and spaced apart side walls 8 integral 'nited States Patent ice . i 2 with the top wall. The back of the cabinet is usually open. The back may be closed by a separate wall 9 which may take the form of a foraminous plate through the corners of whichscrews 11 pass freely but are threaded in the ends of ribs 12, also integral portions of the cabinet 6. Preferably, the ribs 12 are located at the junction of the top and side walls since they are, at these points, least likely to interfere with insertion of the television apparatus into the cabinet. Cross-sectionally, each of the ribs 12 is formed with a head portion 13 which is spaced from the

walls

7 and 8 by a web portion 14. The formation of the head portion 13 is substantially round, in crosssection, and of diameter adequate, of course, to provide anchorage for the screws 11. V

Between the ribs 12 a planar object 16 is fixedly associated with the top wall 7. The object may take the form of the base plate of a television antenna assembly or it may take the form of some other plate-like object such as an instruction book or any other object having opposed parallel edges.

For securing the planar object 16 in association with the top wall 7 a novel clip or fastener 17 is provided for both of the ribs 12. The clip may be formed from a single metallic strip at least a portion of which is capable of at least limited flexing. A suitable clip 17 was made of spring steel about /2 in width and approximately .035 inch in thickness. Intermediate its ends, the clip is provided with a bow or pinch portion or loop 18, the maximum width of which between its two arms is greater than the thickness of the head portion 13. The loop 18 terminates in end portions or grippers 19 which are spaced from each other by less than the thickness of the head portion 13 when the clip 17 is in a state of relaxation. From the grippers 19 the remaining portions of the clip extend awayfrom each other to provide

arms

21 and 22.

In attaching it to the rib 12, the clip 17 is heldtransversely thereto and brought into proximity to the same until the free end of arm 22 engages wall 6' and the free end of arm 21 either engages the wall 7 or the plate 16 held against said wall 7 as indicated in Fig. 2. At this' tends to urge said grippers constantly toward the web 14.

to a limit provided by the

walls

7 and 8. This cooperation between the loop 17 and rib 13 is adequate to anchor the clip to the rib adequately to resist its removal, even" when the arm 21 is bent away from the wall 7 additionally, by the antenna plate 16 between the wall and arm 21. The arm 21 therefore exerts a biasing force on plate 16 in the direction of the top wall which is adequate to retain the antenna plate in association therewith. As shown in Fig. a, pairs of clips 17 may bear against the plate 16 adjacent opposite sides thereof to retain it in association with the top wall of the cabinet.

Although the method of coupling the clips to the ribs, as described, involves springing them over the ribs from points perpendicular thereto, the method of threading the loop portions of the clip over the ribs from their ends at the back of the cabinet is also contemplated. And this is also of advantage when some regions of the clip are less susceptible of flexing than others, such as a construction in which the loop 18 is substantially rigid and the

arms

21 and 22 substantially resilient.

If desired, means may be employed to assist in locating the antenna plate 16 in a predetermined position with respect to the top wall 7. Said means includes stop members or gauge members which extend downward trom the wall 7 and which may appropriately'take the form of spaced apart ribs 23, also integral portions of the' cabinet 6. The ribs 23 may be intimately associated withopposite edges of the plate 16 when it is therebetween andjadjacent the top wall so that there is substantially no edgewise displacement of the antenna plate when it is later urged upward by the clip arm 21. In order that the arm 21 may clear the rib 23 when retaining the Plate 16 in place, said arm is bowed away from the wall 7 from the end of loop 13 until the arm passes over the rib 23 without engagement with the same. Then the arm slants upward toward the plate 16 for engagement therewith. Also if desired, the plate engagingend of arm 21 may be provided with teeth or points 2d (Fig. l) for cooperationwith the antenna plate and better resist its removal from the predetermined position.

Although clips are usually employed in pairs to grip theplate 16 for securing it to the cabinet, the plate may be secured to the cabinet jointly by one of the clips 17 and one of the stops 23.- The manner in which this is possible is illustrated in Fig. 3, where the lower ends of the ribs 23 extend slightly toward each other providing hooks as at 26, so that one of said ribs is adapted to support plate 16 atone of its sides while the force of arm 21 against the opposite side of the plate both supports said other side and prevents displacement of said plate from supporting engagement by the rib 23.

An additional embodiment of the clip is illustrated in Fig. 5, wherein a loop portion 27, resembling the loop 18, may be installed in combination with a rib 28 on a wall which is remote from any other wall. Arms 31 and 32 extend away from each other at an angle adequate for both to be under deflection when the rib 28 is grasped by the loop 27 and a planar object 33 is fixed in association. with the wall '29. 7

Although tworembodimcnts of the invention have been described, other and extensive departures may be made therefrom without departing from the spirit or scope of the invention.
