4 Claims. (Cl. 20-69) This invention relates to scaling arrangements for joints, and in particular to a sealing strip arrangement parti'cularly adapted for sealing doors and the like.

Conventional sealing arrangements for the joints in a door construction are currently constructed of metal strips. These and similar conventional strips are not entirely satisfactory. The weather seal formed thereby, when the door is closed, frequently includes numerous air gaps along the edges of the door, which, in addition to failing to provide a well sealed joint, may result in such vibration of the sealing strip during severe wind conditions that undesirable high-pitched sounds are emitted. Some attempts have been made to overcome this and other disadvantages of known sealing strips, but for one reason or another, they have not been completely successful.

The present invention, on the other hand, proposes a novel sealing arrangement for doors'capableof providing a satisfactory continuous and effective seal along the edges of the door.

Furthermore, it is proposed that the novel sealing arrangement include a flexible, resilient strip arranged adjacent the frame for the door and adapted not only to provide a tight seal with the respective door edge, but also'to act as a shock absorber 'virtually eliminating the noiseincident to closing the door, and further to compensate for variations in door dimensions thereby permitting a greater tolerance while still assuring a proper fit for the door in the door frame.

Still further objectives are to have the novel sealing arrangement of simplified design, capable of being easily and economically produced and installed, and adapted to function satisfactorily under adverse conditions for long periods of time.

Further objects and advantages of the invention will be in part obvious and in part pointed out hereinaften The novel features of the invention may be best made clear from the following description and accompanying drawings in which; 7 p p H n p p Figure 1 is a fragmentary perspective view of a wall having a typical door frame and door construction to which the present invention is applicable;

Figure 2 is an enlarged and fragmentary sectional view taken generally along line 2-2 of Figure 1 and showing an embodiment of the invention in an exemplary mounting position; and

Figure 3 is a fragmentary perspective view of a sealing strip embodying the invention.

In one aspect, the invention contemplates the provision of sealing strips and means for mounting the strips adjacent the door frame parts, with the sealing strips being constructed of resilient material and including a longitudinal base portion, and a longitudinal tubular portion, and with the mounting means including a bar having a longitudinal groove therein in which the base portion of the strip is secured.

In another aspect, the invention contemplates the provision of an integral and resilient sealing strip including ice a longitudinal anchoring or base portion and a longitudinal tubular portion on the base portion, the tubular portion being of generally semicircular configuration in transverse section, with a longitudinal reinforcing web in the tubular portion joining it to the base portion and with atleast one longitudinal sealing lip on the exterior of the tubular portion for intimate sealing engagement to g the jamb parts 22, as indicated in Figure 2. Since the:

novel sealing arrangement of the invention is particularly adapted to be used in combination with door frames for v sealingly engaging the edges of the doors, it will be shown. and described, for illustrative purposes, as applied to the: typical door and frame construction shown in the drawing. However, it will be appreciated thatthe novel seal ing arrangement may be used in other environments for" similar purposes.

The illustrative embodiment of the sealing arrangement: of the invention shown in Figures 2 and 3 includes a. sealing strip 34 and a mounting means 36 therefor,. adapted to be installed along the door frame. This sealing arrangement may be appropriately fitted into each of the

door frame parts

20, 22, 24, if desired, in a manner to be explained hereinbelow;-or it may be fitted only to the jamb 22 and head 20 parts. In any event, it is contemplated that the sealing strip 34 be positioned paralleli to and substantially coextensive with the adjacent edge: of the door and in the path of movement thereof when the:

door is closed.

plastic is believed to be highly advantageous.

The strip 34 further includes a reinforcing web 4t) within the tubular portion 38 and joining it to the base portion 36, as indicated. A bottom wall 42 preferably extends from adjacent an end 44 of the tubular portion 38 to the base of the reinforcing web, andlongitudinall'y extending lips 46 are formed on the exterior of tubular portion 38, for a purpose to be referred. to in more de V will provide an attractive appearance.

tail hereinbelow.

The mounting means 36 for the sealing strip 34, as

indicated in the illustrative embodirnent thereof, preferably is of angulated construction including the leg portions 48, 50. The leg portion 48 is formed with a longitudinal groove 52 therein, in which the base portion 37 of the sealing strip is adapted to be anchored or secured. In this connection, base portion 37 and groove 52 may be of the configuration shown, whereby they will be dovetailed, with the end 44 of the tubular portion engaging the adjacent corner of the bar 36 so that the outline of the tubular portion 38 in this region will desirably merge or be substantially flush with the fiat surface of leg 50, as shown. Thus the combined structure of the sealing strip 34 and the bar 36, when assembled and installed, Although the bar 36 may be made of any suitable material, it is preferred that it be made of aluminum or similar light weight metal, formed by an extrusion process.

To install the combined strip 34 and bar 36 in position in the door frame, it is preferred that the frame Patented May 10, 1960' part in question include a longitudinal shoulder 54 and a longitudinal groove 56 adjacent thereto, in the manner indicated in Figure 2. Further, a recess 58 is formed at the outer end of the shoulder 54. The bar 36 is installed in position by disposing the free end of leg 48 in priate groove 64 extending inwardly from the recess 58. in substantially flush relation to the adjacent surface of the frame part, and with leg 48 abutting shoulder 54, as shown. Suitable means will be provided for anchoring the bar in this position. For example, as shown, a longitudinally and inwardly extending portion 60 may be provided on the leg 50, as illustrated, and having serrations 62 or the like thereon to be fastened in an appropriate groove 64 extending inwardly from the recess 58. Additional fastening means may also be utilized if desired, such as screws extending through the leg 50 at right angles thereto, and into the underlying frame. I

It will be understood that the sealing strip 34 and bar 36 preferably will extend substantially co-extensively with the frame part on which they are mounted, and the tubular portion 38 will be disposed at least somewhat in the path of the door 28 as it is being closed, as indicated in Figure 2. By virtue of this construction and arrangement, it should be evident that when the door is closed, the edges thereof will engage and deform the tubular portion 38 of the sealing strip. The reinforcing web 40 enables the tubular portion 38 to maintain its shape and will provide a certain desirable amount of stiffness thereto. The main part of the tubular portion, however, which is the part primarily engaged by the door when it is closed, possesses a greater degree of resiliency than that part to which the reinforcing webis joined. Hence, when the door is closed, tubular portion 38 will be readily deflected into firm sealing engagement therewith substantially throughout the entire length thereof. Additionally, the longitudinally extending lips 46 will also be deflected by the edge of the door when it is closed, and thus, these lips will also be resiliently and firmly pressed against the region of the door edge to provide still further assurance that a desirable continuous seal will be efiected along the joint.

It should be reiterated that among the various virtues of the sealing arrangement of the present invention, it will be noted that the seal effected thereby virtually eliminates the possibility of any air leaks and wind noises caused thereby; it absorbs the shock of door closing movements thus minimizing noises incident thereto; and by projecting inwardly into the path of closing movement of the door and being flexible, it will provide for greater tolerance in the dimensions of the door, thus enabling a desired sealing action to be elfected with doors that might he slightly undersize or slightly oversize.

The present invention will thus be seen to completely and effectively accomplish the objects enumerated hereinabove. It will be realized, however, that various changes and substitutions may be made to the specific embodiments disclosed herein for the purpose of illustrating the principles of this invention, without departing from these principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
