6 Claims. (Cl. 20-56.4)

This invention relates to mounting strips and is particularly directed to inexpensive mountin strips for forming weather-proof joints and the like between two plane surfaces, for example, a door panel and a door frame.

Itis,-therefore, the primary object of this invention to provide a mounting strip useful in joining two plane surfaces, which mounting strip firmly holds the two surfaces within grooves therein and which includes a longitudinally extending flap made from resilient material which, when placed in a locking groove within the strip, causes the strip to wedge against the vfiat surfaces and simultaneously forms a cushion substantially along the joint thereof. In some cases it may be desirable to form such a strip with dual cushion ing and wedging flaps on both sides thereof, but in all cases, the flap or flaps has the dual function of spreading the strip so as to wedge the panel or other articles clamped thereby firmly within the strip and simultaneously acting to form a cushion therealong.

In the manufacture of automobiles, refrigerators and the like, it is often desirable to mount instrument panels or glass by means of a resilient strip so that the piece being mounted is resiliently held within the mounting member and wherein the mounting piece may be removed from its mounting in a facile manner. For example, window glass can be the use of such strips. Instrument panels of automobiles may likewise be held in place through the resilient mounting means, to be described in detail hereinafter.

Another application of strip is directed to refrigerator doors wherein a metal door is fabricated which has an inturned edge therearound and wherein an inner door panel made of metal or plastic is to be mounted therein. In this connection, the edges of the inner door panel are dimensioned so that they are closely spaced to the inner edges of the door. mounting strip as described hereinafter, may e used to hold the panel to the door and a resilient flap used as a wedging means for locking the panel and door in place has the dual function of acting as a sealing strip around the door when the door is mounted on a cabinet. Obviously, a sealing strip of the class described has many other utilities and in all cases, presents a means for easily mounting one part upon another wherein the parts may be detached with great ease and wherein if desired, a sealing strip and cushion is provid Further objects and advantages of the present held within a door frame through m improved mounting invention will be apparent from the following dewise forms a cushion scription, reference being had to the accompanying drawings wherein preferred embodiments of the present invention are clearly shown.

In the drawings:

Fig. 1 shows a fragmentary view in perspective of a section of my improved mounting strip show: ing the flap and mounting strip. Fig. 2 is a fragmentary view in perspective of a portion of a strip gripping plate-like members wherein the flap is in looking position and like- .along one side of the strip.

Fig. 3 is a view in perspective of another type of strip wherein another type of locking flap is provided.

Fig. 4 is a view in perspective of a portion of a strip as shown in Fig. 3, wherein two plate-like members are joined therebetween and wherein a locking flap is in wedged position, and

Fig. 5 is a sectional view of another embodiment of a strip similar to that shown in Figs. 1 and 2 wherein a double cushion is provided on either side of the strip.

In Patents Numbers 2,189,137 and 2,189,138 entitled Connector strip" and issued to F. R. Eichner, there are described several typeset sealing or mounting strips. In the Eichner patents the connector strips are made of resilient material having mounting grooves therein which are normally in either open or closed position and wherein additional longitudinal grooves are utilized which are filled by means of a separate wedge of resilient material for turning the flaps or the edges of the mounting grooves inwardly and thereby seal the connector strip firmly to the glass or other material being mounted. These strips have great utility in the assembly of many automotive devices. The present invention is directed to the improvement in these strips wherein the wedge used for closing the flaps of the Eichner strip is formed integral with the connector strip and wherein in some cases, this wedge forms a cushion or sealing means on one or both sides of the strip.

Referring specifically to the drawings, Fig. 1 shows a connector strip 20 in persepective which includes a longitudinally extending groove 22 therein and an opposed longitudinally extending groove 24. The grooves 22 and 24 are adapted to receive the parts to be connected as designated at 26 and 28 respectively in Fig. 2. When parts 26 and 28 are in position, it is apparent that the groove 24 due to its configuration in section, definitely grips the part 28 but that the groove 22 is a loose fit on the member 28. In order to lock amazes a the member 2! within the groove 22, a third longitudinally extending groove II is provided which is disposed intermediate the grooves 22 and 2|. The groove 3| includes three longitudinally extending semi-circular depressions so that a section of the groove has a shape somewhat similar to a three-leaf clover. A illler strip 8: is provided which has a configuration insection approximating tint of the groove 3| and said filler strip is connected by means of a flap 34 at the upper lip 38 of the"groove 24. In assembly. the strip 82 is then pressed into the groove II by means of a tool somewhat similar to a button hook or the like which spreads the groove to permit ingress of the strip 32 whereupon the upwardly extendlng flap II of groove 2! is forced downwardly to firmly grip the member 20. In this position, the strip I2 causes the flap It to take the shape of a longitudinally exte tube, whichtube forms a resilient sealing strip 38 along the connecting strip 2|.

The integral connection between the flller strip 32 and the connecting strip II has great utility. To begin with, the construction provides an integral sealing means 34 when strip 32 is in looking pwltion and in this structure it is also possible to conceal screws or the like which pass through the flap 36 of the strip 20. Similarly, the entire device is of a better appearance and reduces the number of parts required since the filler strip is integral with the connecting strip and no additional filler strips are necessary. Furthermore, in production when the connecting strip is cut to length the filler strip is cut to the exact length required since it is integral with the connector strip thereby eliminating considerable inaccuracies heretofore found in use of separate tiller strips.

It is apparent that if a double sealing strip is desired that a second filler strip 40 and flap may be provided at the opposite side of the connector strip 20 as shown in section in Fig. 5.

When a cushion sealing is not desired, the length of the flap 34 is reduced as shown in Figs. 3 and 4 wherein a flap .2 is utilized together with the filler strip 32. In this connection when the filler strip 32 is in position within the groove 30 no appreciable resilient seal is present but the concealing ability of the flap is still apparent. Similarly, an integral filler strip and the connector strip is provided.

From the foregoing it is apparent that I have provided a new type of connector strip wherein a filler strip is made integral with the connector strip and in some cases, is connected thereto by means of suflicient material in the flap so that when the filler strip is in position, that the flap forms a resilient bumper or sealing strip at one or both sides of the connecting strip.

' While the embodiments of the present invention as herein disclosed, constitute preferred forms, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
