Abstract
Abstract of the Disclosure Disclosed herein is a door lock attachable to the edge of a door and selectively deployable to engage the floor adjacent the door to thereby prevent the door from opening More specifically, the door lock comprises a slide adapted to be clamped to the door, the slide engaging a vertical leg of an L-shaped bracket, the horizontal leg thereof being provided with a plurality of V-shaped cuts forming downwardly directed teeth for engaging the floor or the carpet adjacent the door. Included also in the hori-zontal leg are two adjustable screws which may be turned downwardly to provide further engagement with the floor.
Description
:~:
The present invention relates to door locking mechanisms, and more particularly to mechanisms attached to the edges of a door for securiny the motion thereof.
With the present increase in crimes against property, and particularly with the increase in the incidents of burglaries, various securing devices have been developed to protect the modes of ingress and egress from a dwelling.
~ypically such devices have been frequently conformed to engage various holes or other openings in a door or a window ~;~
and therefore entailed modification of the door structure in the use thereof. In many instances such modifications are not permu.tted by the landowner, thus limiting the use thereof and leaving the tenant often unprotected. For this reason selectively attachable devices whic~ Ln their use do not require modification of the door have had recent demand and it is a device of this kind that is presently set out -~
Accordingly, it is the general purpose and object of the present invention to provide a door loc]c assembly which by virtue of its structure may be selectively attached to the eclge of a door.
Other objects of the invention are to provide a securing mechanism adapted to be deployed between the edge of the door and the surrounding structure which, by virtue -~
of its features, will oppose -the normal opening motion of the door.
Yet further objects of the invention are to provide a door securing dev1ce which is easy to produce, convenient in use and requires no maintenance.
In accordance with the invention, a door securing device adapted to oppose the opening of a door comprises:
a U-shaped clamp conformed to engage the edge of sa:id door b~ ~
said clamp including one vertical surface provided with outwardly directed inturned lips along two parallel edges thereof, clamping means for releasably securing said clamp to said door; an L-shaped bracke-t having a vertical leg conformed for insertion between said inturned lips and a horizontal leg provided with a plurality of V-shaped cuts each formlng a tooth-like structure turned out of the plane of said horizontal leg, and adjusting means for selectively ~
securing saicl bracket rela-tive said clamp. ' Again, these and other objects are accomplished ' within the present invention by providing a yenerally U-shaped clamping slide conformed to engage t'he edge of a door and :includirlg a cl.c~npir.g scr~w extendirlg therethrough for attachrnent to the door. Formed along the edges of one leg of the slide are two inwardly-turned slips having received therebe-tween an L-shaped stop bracket provided with a set screw for selective adjustment of the cleployment height thereof, The horizontal leg of the L-shapecl bracket includes a plurality of V-shaped cuts, each forming a tooth-like structure, the tooth-like structures being bent out o the plane to form downwardly directed teeth which rllay 'be pressed into the flooring to secure the door. In addition the horizontal leg is also provided with two thumb screws ~ `-engageable in the flooring which may assist in the securing thereof or in t'he process of withdrawal.
The foregoing structure is uniquely adapted for various temporary uses, and can be carried along by persons '~
traveling for use in hotel rooms and other -temporary '~
lodging.
The invention will now be described with reference to the accompanying drawings which show a preferred -form thereof and wherein~
FIGURE 1 is a perspective illustration of a .
removable door lock constructed accord~
ing to the present invention, -~
FIGURE 2 is a front view of the door lock shown in E'igure 1 illustrating the manipulative -deployment thereof, FIGURE 3 is a side view of the inventive door .-lock as installed onto the edge of a .
door, said door lock being articulated out of latching engagement to permit the ~ :
opening of the door, FIGURE 4 :is a side v.iew of the inventive door lock man.ipulated to a ~ocking engagement, and FIGURE 5 is yet another perspective illustration ~;:
~, of an alternate door lock adapted for ~;
,-transported use.
As shown in Figures 1, 2 and 3, the inventive door --~
lock assembly, generally designated by the numeral 10, com-prises a U-shaped clamp 11 having an opening dimension some-what greater than the thickness of a door D. One vertical .-leg oE the U-shaped clamp 11, and particularly the ley ~ .
deployed on the interior surface of the door, is provided with two opposed edge lips 12 and 13 extending partly along ~-the lateral edges thereof conformed to receive therebetween, ~. -in sliding translation, the vertical element of an L-shaped ~;
bracket 15. This same vertica~ leg of bracket 15 also in~
cludes a centrally located longitudinal slot 16 through which ;, a screw 17 engaged to the adjacent surface of clamp 11 ~`
extends. Screw 17 threadably engages a wing nut 18 and it is by this wing nut that selective adjustment of the ~:
deployment height of the bracket 15 is madeO Extending also through slot 16 and threadedly engaged in clamp 11 is a thumb screw 20 terminating on the interior of the clamp in a clamping foot 21 for providing the clamping force against the door D. The horizontal leg of the L-shaped bracket 15 includes a plurality of V-shaped cuts each forming a tooth~like structure 25, the apex of each tooth being directed downwardly out of the surface of this leg.
As sho~m in Figure 4 it is these tooth-like structures 25 that engage the flooring F adjacent the door thus precluding the inward articulation of the door. In ~ -addition, the horizontal leg of t,he 'bracket 15 may be pro-vided with addit~onal two thumb screw~ 27 and 28 terminating :in sp:i'ked ~nds on the ]ower surface thereof, thurnh sc~ews 27 and 28 providing additional engagement with the flooring F and furthermore by the threaded engagement thereof relative the bracket 15 provids the necessary upward forces in order to withdraw the -teeth from the flooring to thus permit opening. More specifically in the normal unengaged confi-guration the horizontal leg of bracket 15 is carried above t'he surface of the flooriny with the teeth out of engagement.
Should secure closing be desired the user may release the wing nut 18 and force the bracket 15 downwarclly by stepping on the horizontal surface thereof. Once so located the wing nut 18 may then be again secured and the acute angle align- ,' ment of teeth 25 will then propagate into the flooring on the inward forcing of the cloor. Should withdrawal be desired the thumb screws 27 and 28 may be threadably advanced through the horizontal leg of bracket 15 forcing the teeth 25 out of engagement and allowing for manual upward arti-culation of the bracket.
_ 4 _ By virtue of -the foregoing arrangement of parts a substantially simple locking structure is achieved which does not require elaborate machining or modification of the -~
door structure. This same arrangement of parts may cooperate with soft flooring like rugs, the number of teeth and the area of the horizontal leg of bracket 15 being sufficient to provide the necessary resistive forces against unwanted opening of the door.
As a further alternative a portable door stop use-ful with carpeted floors is set out in Figure 5. In thisillustration a single L-shaped bracket 100 is providecl with a plurality of downwardly inc:Lined teeth :L25 formed in the horiæontal surface 101 thereof~ The horizontal surface 101 extends in the ~orrn oE tabs 102 and 103 beyond the croolc Oe the '`L" and it is these tabs that are insertable between the lower edge of the door and the door sill. When so positioned the teeth 125, by virtue of their alignmen-t, are driven into any fibrous floor covering, effecting a door closure.
I~lis last implementation is of particular utility to those in the course of travel, being conveniently trans-portable and easily applie~d. Teeth 125 directed against the the path of opening are maintained in contact with the floor covering by an opposed set of teeth 126, thus presenting a point which is imbedded by the door.
Obviously many modifications and changes may be made to the foregoing description without departing from the spirit of the invention. It is therefore intencLed that the scope of the invention be determined solely on the claims appended hereto. ;
