The present invention relates to protectors for doors and windows and has for itsmain purpose. the sealing of the bottom of thedoor against 1 weather, wind, ingress of dust, moisture, vermin,"

etc.

This invention involves; a r-improved type of I weather seal for doors and windows which is extremely effective-in operation, which is uncomplicated and easy tomanufacture, fabricate and install and which is of extremely ruggedac'onstruction and designed for unlimited periods of service. The present device moreover hasqthe outstanding characteristic that the top member thereof may be easily removed for purposes of cleaning the sill or threshold. V

One object of the present invention then is to provide a device ofthe character described which will have weather stripping characteristics operable to completely seal any gap that there might otherwise be between the door orwindow and door or window sill.

Another object of the present invention is'to provide a device of the character described which will have flanges which may be bent to any desired position to provide for installation in rooms having, wall to wall carpeting and the like.

Still another object of the present invention, is.

to provide a device of the type described which will have a removable cap member which is normally held in place by a latching mechanism and yet which may be easily and;quickly-removed from the stationary body portion when desired.

Yet another object of the present invention is flat or flush with the stationary body member,

said cap member being further adapted to rise or be elevated above the structure when thedoor or window is being closed.

A still further objectof theinvention is topro vide the door or windowwith an adjustable actuating element by means of which the 'movable cap member is brought from its normal flush position touits elevated position when actuated by the closingdoor or window, so as to provide effective sealing means and slope for drainage of water. 1

.With the above and other objects in View as 10 claims will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, as hereinafter more specifically set forth, claimed and shown in the accompanying drawings which-form a part ofthis applicationfor Letters Patent.

In the accompanying drawings are shown several preferred and practical embodiments of the invention, it being understood, however, thatthe drawings are merely illustrative and that the-in ventive-concept is susceptible of other embodiments and utilizations, and that the illustrated embodiments likewise are susceptible of a wide range of variation and modification without departing from the spirit of the invention or the scope of the appended claims.

Fig. 5-is a detailperspective view showing the:

latching mechanism of Fig. 4 with the movable cap member removed;

Fig. Gw-is'a view of the latching mechanism shown in Fig.5 taken along line 6a6a; and,

Fig. 6b is .a view taken along line Sb-Gb of Fig.5;

Fig. 6c is a view taken along line ticor Fi 5;

Fig. 6d is a view of a detail of Fig. 5;

Fig. 6c is a detail view of the latch member of old 46 by any suitable means, such as, for example, the screw member 18. The door which is to be sealed has been indicated by the reference numeral 20. Reference numeral M has been used. to generally designate the stationary body member, the cross-sectional shape of which is illustrated most clearly in Fig. 1. The stationary body member has leg portions 24 and 26 which contact the sill or. threshold l6. there also. being slanting flange members28 and 30: which also contact the sill or threshold I6 as is shown most clearly in Fig. l. A web member 32 having slant-- ing and horizontal portions runs between the legs 24 and 26 as shown. The slanting flange: members 28 and 30 each haveagroovet extending the length thereof, saifgi'ooveenabling the user to bend the slantingnflangeemembers.28e and 30 up as shown in dotted lines in Fig. 1, ,or. down to provide contact. with uneven sills 'or' thresholds 16 as may be desirable in certain applications such as. for'example', when'wall tozwall" carpeting I02 is used.

The movable cap member oftlie dvioe hasbeerr* generally indicated bythe reference numeral 36 and comprises a. generallyrectangul'arstrip hav ing at one side thereof -a=downwardly extendihg longitudinal rib 381which. withitlieaflanges-thereon, provides two horizontal 'grooves dfl and l zgion'e on each side of the rib', as'is shownmost clearly' in'Fig'. 1. The groove 42 0f 'the 'longitudi nal-rib 38 engages with a flange ll' tdforma pivotalf tongue and groove 'connecti'on around whichthemovable cap member '36' may revolv'ej andsaid tongue and groove connection being of such character that when the cap- =memberis pivotally moved upwardly toward thelower edge or the door, a cramping and binding action is present in the tongue and groove connection-to efiect'an air-tight seal.

Figs. 2 and 3show a-cam l'atch member whichluio has been generally designated'bythe reference numeral 46. The cam latching members 46 are' secured to the underside. otth'e movable cap member 36 by suitable fastening meansysuch' as the bolt member 48'; the cam latch' fli'being fixedly 5 secured to said'boIt'memberAB' by threading'in cap member 3t and bradding' under-member so that turning the bolt 48 will also turn-thecam latch 48. The cam latch member 46" has ith'e shape shown in Fig. 2 and has a fiat 'side 158 i adapted to engage in thegroove -dfiin theg cap; member 36 which haspreviously been*describecLL The cam latch 46 also has a flat edge 52' which' is adapted to fit into thegroove-=54 in :the stationary' body member l4. (see-Fig." 1?) The reference numeral 55 designate rcoilectispringii whichencircles'the bolt '48, one'end ofi'lhespring 56 being attached to thecam latch-46 and th'ec other end engaging the: groove: 40 as :is shown most clearly in Figs. 2 and 3. The latching earns 46 normally hold the movabl capmember-36 down against the stationary body member l4 so". that the movable cap membercwillilie flat against the stationary bodymemberwhemthe door Z-llfis open, and they also provide means whereby :the. movable cap member 36 may beeasi'lyzandnuickly removed from the stationary bodymemberfll for: cleaning and like purposes; This is accomplished; by turning the bolt 48 through A of a turn: thus; alsoturning the cam latch: 46 to:- then-position shown by means of the dottedzlines;:inrFigr;2,1. thus removing the side;52 out-ofjen'gagementwithizithe groove 54 in.thestationary-.'bodyflmember:22:; so that the movable capmember-36 may bepulledt; out :of engagement; withrthe flange a. 44]: whereby 75 the movable cap member 36 may be removed from the device, and th device cleaned of accumulated dust and debris. After the device has been cleaned the movable cap member 36 may be slipped back into position so that the groove 52 of the longitudinal rib 38 again engages the flange 44, after which the movable cap member is pressed down against the stationary body portion:.22 landtheibolt 48 given-. /e-of aturn back, wherebyzthe edge 52 of theqcam latch i465 gain engages the groove 54 in the position shown by the solid lines in Fig. 2, thus latching the movable cap member 36 in place.

The-door 20 carries a hook member 58 which may.be.fixedly.seoured to the door 29 by any suitable means such' as, for example, the screws 60:. Thethookrmemberzfl is adapted by bending the leading. corner downward to sli into a notch under the movable cap member 36 by a scissoring action as the door 20 is closed, thus lifting up the =movable -caprmember=36*asis shown most clearly irr- Fig; 1' andproviding' an' effective weather" seal 2 to prevent the entrance of wind, dust;-debris'-:andverminbetween the bottom of the door 20 and the threshold or sill 16. The notch is notvis'ible-in-Figi 1;- however, this same structural detailwill be described in connection with a later figure. Wherrthe-doorQU-is opened the hook 58 moves out' from undrthemovable cap member '3Bfiand tlie 'spring56 urgesthe movable cap memberdown' against" the stationary body memberZZ -so -that-tIie movablecap member 38 willlie flat. against the stationary body member I4 so that users of thenoor will not accidentally be tripped by the movabl- 'cap'memb'er 36 when crossing the threshold? If" desired, a suitable wiper strip '62 may be carried by the door 20 to whichit is fik'edly secured by'any suitable means, such as; for example-, the screws 64. The wiper strip: 62 provi'ds additional Weatherstrip protection between the bottom of the door Ell-and the threshold 16:

If desiredfsuitable weepholes (not shownymay be provided in the de'vice l4' t0 afford adequate drainage for-water' and-the like which may enter the devices Further; as"a-n-additional protection againstthe entrance of wind and dust and the like; suitable material 66, such as putty, or the li-ke may-be pl'aced around'the legs '26 and 26 'as isshown mcst clearly inFig. 1.

Fig; 4 =shows-'a*modified"form of the improved weatherstrip-of-my invention; This form of the invention*contemplatesthe usoof-the same type of movablecap member-'36 previouslydescribed in connection WithTi'g'si l;z'and' 3; but contemplates asslightlydii frent shape of 'stationary'body portion 2 2; the cross-section' of which is shown most clearlydmFig-r 4;" andforms-a somewhat more compact device than that previously described. The legs 68-; 'lll and -12} as well as the'rear of the stationary body portion 22contact the sill or threshold l6? The rear ofthestationary body portion: 22 terminates'in-"an'upstanding, inwardlycurvedtongue-portion '14 adapted to engage the groove-:42fofthe longitudinal-rib'38 of the movable cap member 36 so that the same type of hinged pivot? aroundwhidhthemovabl'e-=cap member 36 mayrmove-"ls -formed as-"that previously described in connection with Fig. 1.

Asuita'blezhookmember 58 is secured to the doorxZ0rbyany:suitablermeans-"such as, for example; the-ccscrew members "BU-as is shown most clearlyrimFig. 41-. Theiaction of' this weatherstrip is quite similar to that already described in con- 12 nectioniwith ;Fig:'.1-,; thehookizmember 58 scissorwere ing under the movable cap member 36 whenthe door isclosed, thus lifting the movable'cap'member 36 up against the bottom of the door- 28 to form an efiective sealing means against the en-' trance of wind, dust, debris, and vermin. If desired, a suitable wiper strip 62 secured to the door 28'by any suitable means such as, for'example, the screws 64 may be used to provide additional protection against the entrance of wind and dust as is shown most clearly in Fig. 4. When the door 26 is opened the hook member 58 moves out from under the movable cap member 36 so that the movable cap member lies flush against the stationary body portion 22.

Figs- 5 and 6 illustrate another type of latching member from that previously described which is designed to normally hold the movable cap member 36 in place against the stationary, body porbeen illustrated in connection with Fig. 4 al-H though it will be obvious that it could be used with equally good results with the type of weather strip illustrated and described in connection with Fig. l, and also that the cam latching means shown and described in connection with Figs. 1,

in'g member 82 has cut therein a rectangular slot.

84 through which the rivet 80 passes. The latching member 82 also has a suitable tab portion 86 which provides handle means for moving the said latching member from latched to unlatched position. Also, the lower or headed end of rivet 80 has spring 99snapped on it, which causes a downward tension on rivet 60 and cap member 36.

.6 the stationary body port on 22 by pulling the said movable cap member36 forward so that the I tongue portion 14 of the stationary body portion 22 no longer engages the groove 42 of the longitudinal rib 38 of the movable cap member 36 and themovable cap member may be entirely removed from the device for cleaning and other purposes. When it is desired to replace the movable cap member 36 on the device it is only necessary to engage the tongue portion 14 of the stationary body portion 22 in the groove of the longitudinal rib 38 of the movable cap member 36, press the movable cap member 36 down onto the stationary body portion 22 and then move the tab 86 of the latching member 82 to the right, where it assumes the position shown by means of the dotted lines in Fig. 5, where the tab portion 88 again engages the groove 54 in the stationary body portion 22 and the movable cap member 36 is thereby held in place.

One corner of the edge of member 58 (Fig. 1 or Fig. 4) is bent down, so that as the door is closed, this corner will engage in a notch as shown at I! in Fig. 6b which is formed under the edge of member 36 to lift this member upwardly toward the bottom of the door as it is opened and 2 and 3 could equally well be used in conjunction The tab portion 86 lies slightly above the plane of a second tab portion which has been. designated" portion 88 normally engages the groove 54 of the stationary body member 22 (see Fig. 4) so that v the movable cap member 36 with the aid of spring 99 is held down against the stationary body member 22 so that the movable cap member will lie flat against the stationary body member when the door 20 is open. When it is clesired 'to remove the movable cap member 36 from the stationary body member 22 for cleaning and like purposes, it is only necessary to slide the tab 86 to the opposite end of the slot 18 whichhas been cut in the outer wall of the stationary body portion 22, to a position shownmost clearly by the,

solid lines in Fig. 5. This movement causes the latching member 82 to movein the same direction I and disengages the tab portion 88 from the groove 54 in the stationary body portion 22 so that the movable cap member 36 may be removed from cause and air-tight cramping action of the member 36 with the stationary body portion.

Fig. '7 shows yet another modificationof the improved device of my invention. This modification is especially useful in applications on casement type windows, and contemplates the provision of a stationary body member 22 which may be secured to the window sill 92 by any suitable means, such as, for example, the screw member l8. The stationary body member 22 may-have the shape shown in cross-section in Fig. '7 and includes a tongue portion 94 and a longitudinal groove 96. A movable cap member 36 of the type previously described may be used in conjunction with the device, the movable cap member 36 having a longitudinally extending rib 38 having two horizontal grooves and 42 cut therein, as previously described. The groove 48 of the movable cap member 36 engages the tongue portion 94 of the stationary body portion 22 to form a hinge pivot as previously described. The casement window which has been generally designated by the reference numeral 98, carries a hook member 58 which may be fixedly secured to the window by any suitable means, such as, for example, the screws 66. The hook member 58 is adapted to slip under the movable cap member 36 by a scissoring action as the window 98 is closed, as previously described, thus lifting up-the movable cap member 36 as is shown most clearly in Fig. 7 and providing an effective weather seal to prevent the entrance of wind, dust. debris and vermin between the bottom of the window 98 and the sill 92 When the window 98 is opened the hook 'member' 58 moves out from under the movable cap member 36 and the cap member lies flat against the stationary body member 22. If desired, a suitable wiper strip 62 may be carried by the window 98 to which it is fixedly secured by any suitable means, such as, for example, the screw 64. The wiper strip 62 provides additional Weatherstrip protection between the bottom oi the window 98 and the sill 92. I Suitable latching means such as that described previously in connection-with Figs. 2 and 3 or the type described in connection with Figs. 6 and 7 may be usedin conjunction with the device of the type previously described in connection with Figs. 6 and 6 being shown in Fig. 7. The latching mama meanstprovids-sa"metliodlror easily, and quickly" removing? the movable "caplim'emb'er' 3 6. from the 7 device fonple'am'ngf; and other purposes "as has:

been'alrleady fully described.

It will 'b'eunderstoodj thafth'e -forms'of the-in 1 vention' herein shown and described are to be taken as preferred andpracti'cal embodiments of the same, and that variou'sichanges may be made, in shape, {size and arrangement of parts without 7 departingrfrom the spirit I'of f the invention or, the

scope of the appended'claims. By way ofexample, the various stationary body portions 22 may haveiweep holes (notfishownffor drainage. purposes, alsoputtyjorother sealingsubstances may,
