CLOSURE s'r IP Application fi led March 16,

My invention relates to a closure strip, and while primarily intended for-use in connection with-doors, windows, shutters, and the like, for rendering such closure elements .25 noiseless in operation, weather and dust proof,

itwill be obvious that the device may be employed with-other types ofstructures, and for any other purposes wherein it is found to be applicable. I V Important objects of the invention are to provide a closure strip-of the charactendescribed, which may be readily installed to any type of closure element already erected as well as form a component part of a new structure, which embodies a replaceable and resilient cushioning member, which is simple in its construction and arrangement, durable and eflicient inits use, compact, attractive in appearance, and comparatively inexpensive to manufacture, install and maintain.

With the foregoing and other objects in view which will appear as the description pro ceeds, the invention-consists of the combination and arrangement of parts and in the 7 details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereindisclosed can be made within the scope of the claims hereunto appended without de-' parting from the spiritof the invention.

In thedrawing wherein like numerals of reference 1 designate corresponding parts throughout theseveral views:

Figure 1 is a transverse cross sectional view of my improved closure strip and of associated'closure elements, the latter being broken away.

Figures 2 and 3 are, respectively, front and perspective views of the device.

F igurest and 5 are, respectively, inner edge and end views of a corner member embodying the present invention.

Figure 6 is a transverse cross sectional view of the device embodying a modified form of cushioning member, and illustrating its adaptation with metallic closure elements.

Referring in detail to Figure 1 of the drawing, the invention is therein illustrated as embodied in a wooden door structure of the usual construction. Thedoor structure in- 1931. Serial no. 522,855.

cludes a door l'and one of the upright mem} bers 2 of the associated door frame.

My improved closurestrip comprises an elongatedbody portion 3, and while prefer ably constructed from metal, it willbeapparentthat'the same'may be formed'from any other suitable material. The body-portion 3* is formedwith achannel extending longi tudinally along theinner edge and throughout the entire length of the formerwkjT-he channel 4; isopenatits inner side,as -at-5, is. mainly disposed'at thefront sideof the body portion 3, and is somewhatmore than semi cylindrical in transverse cross section,

Thefront sideof the'body portion 3- is providedwith a pair of reenforcing ribs, 'respec' tively indicatedat 6 and 7 The rib 6 is com-' paratively narrow and-disposed on theoute-r edge margin of the bodyportionfi. The-rib T-is relatively=wide and disposedcontiguous to the channel-4. The ribs6 and 7 are-preferably of uniform thicknesses, and in conj unction with the channel 4, establish the required rigidity of the body portion 3.

The bodyportion 3, when employed-in a door-structure, as illustratedin thedrawing, extends vertically against eachof the upright. members 2 and horizontally against the head member of the door frame, and replaces the ordinary wood j oint strip now commonly.

used inwood door structures for-limitingthe closing movement of'theassociateddoor, and for closing the oint aroundthelatter in the doorframe. I f '7 a The body portion3 issecured in positionlto the doorwframe by a plurality of screws 8, i

which are engaged in spaced countersunk apertures 9 providedtherefor in thewide'; rib Tofthe body portion.

"The back side lO"of'the1body portion 3, is flat andeXtends-Ion an even plane-throughoijit its; area, with theexceptionofl a sharpiseate .ing ridge 1"l,which is disposed adjacent to the channel '4 and extends longitudinally throughout the length of theibody portion 3.

door fnamei members, thereby providing a j-uncturebetweenthe latter and the body-por tion 3 that is impervious to the passage of air or any extraneous matter.

Corner members 12,, having a transverse cross sectional contour identical to the body portion 3 and likewise secured to the upper corners of the door frame by screws, are provided for establishing ,continuitybetween the upper ends of thebody portions 3 secured to the upright members of the door frame and respective ends of the body portion 3 secured to the head'nie'niber of the-door frame.

' A tubular, cylindrical cushioning member 13, preferably constructed from soft rubber,

is mountedin the channel 4:,andextends throughout the lengths "of the body portion units and corner members 12employed 1n the door structure.' The cushioning member 13,

being tubular and constructed from soft rub- I her, is susceptible of sufficient distortion to allow the same to be forced into and from the channel 1 through the opening 5 at the inner side. of the latter. I

The inner side of the cushioning member 13 projects through the opening 5 in the 1 channel 4, as clearly shown in Figure 1. This projecting portion of the cushioning member 13 provides the abutment engaging the side and top edgemargins of the door 1 when the latter is in the closed position.

' As the cushioningmember 13 is inherently resilient, and; the channel 4t hassomewhat more than a semi-cylindrical configuration,

7 the former, when forced into the channel 4,

fwill securely grip the latter 'and maintain.

itself in position until forcibly removed for replacement or forIany other'purpose required.

An important advantage in the use of my improved closure strip, is that it will render;

the closing of doors absolutely noiseless, whereby its installation, to all doors of homes, public buildings, hospitals or votherinstitutions, is invaluable in obviating the incessant V V slammingof door so'annoying to the occu- V pants ofzthe buildings. Further, owing to v the flexibility of the tubular cushioning member l3,the associated door will closely engage same, and thereby provide a closure joint that is dust, weather, and almost sound proof.

' Figure 6 illustrates the adaptation of the present invention to a metal door structure,

which includes the door.14= and the frame member15. In securing the body portion 3 to the metalframemember15, a filling strip 16, constructed from rubber or any other suitable-material, is interposed between the back of'the body portion 3 iand'the frame member 15 to compensate for the seating ridge 11,

whichjof course, cannot be forcedinto the metal frame member 15; The filling strip 16,

however, providesran effective weather proof joint between theilbodyportion 3 and the metalframemember15. v r Aymodified'form of thecushioning member isshowninthe embodimentof the 1111 6111; -:2
