United States Patent 3,475,929 PORTABLE LOCKING DEVICE Richard I. N. Weingart, Nassau, Bahama Islandsv Continuation-impart of applications Ser. No. 615,651, Feb. 10, 1967, and Ser. No. 645,778, June 13, 1967. This application Dec. 9, 1968, Ser. No. 782,278

Int. Cl. Ec 19/18 U.S. Cl. 7014 6 Claims ABSTRACT OF THE DISCLOSURE A portable auxiliary locking device for doors in frames, and including a bar provided with a hook at one end which is received in an opening in one of the members, the bar having plurality of spaced holes, a locking device carried on to the hook bar and having anopening to receive the bar in close fitting, free sliding relation, and comprising a flat housing with an internal recess, and a locking plate pivoted within said recess, and provided with a finger which enters one of the holes in the bar to lock the bar to the locking device, the plate and housing having overlaying apertured projections to receive a padlock to secure the plate in locked position.

The present application constitutes a continuation-inpart of my two earlier applications, Ser. Nos. 615,651, filed February 10, 1967, now Pat. No. 3,416,333 and 645,778, filed June 13, 1967.

This invention relates to portable locks, primarily for travel purposes, for closet, desk and dresser drawers in hotel rooms, and for a variety of other purposes, and which usually employs a padlock for the locking element. The lock of the present invention may also be used as a supplemental lock for an apartment house door in place of chain locks which are not too satisfactory. The device of the present invention employs an elongated locking bar with a hook shaped abutment at one end which is inserted in a strike plate opening in a door frame and extends forwardly through the space between the door and frame, the locking bar having spaced abutments or slots extending over a portion of its length. A locking device consisting of superimposed plates which are spaced apart to provide a narrow recess therebetween, has an opening to receive the locking bar, which latter is positioned perpendicular to the flat locking device. A plate with a locking finger is pivoted within the recess, the finger engaging one of the' abutments. Both the locking device and the pivoted plate have angular extensions with holes therein which overlie each other when the pivoted plate is in locked relation. A locking device such as a padlock has a shackle which passes through the holes in the lugs, secures the parts in locked relation.

In said application Ser. No. 645,778, there was provided a locking device with a sliding plate which moved longitudinally in a recess between walls of thelocking device from an unlocked to a locked position. The present device is similar in most respects to said earlier locks except that the plate is pivoted within the locking device so it has arcuate rather than straight line movement from unlocked to locked position.

In the drawings:

FIG. 1 is a broken horizontal section taken through a door frame and door and showing the locking device of the present invention with the parts in locked position;

FIG. 2 is a front elevation of the device;

FIG. 3 is a side elevation of the hook bar and the locking device in locked position thereon; I

vFIG. 4 is a broken front elevation similar to FIG. 2 but showing the pivoted locking plate in elevation and in locked position;


. forward movement of the door, shown at 12. The door frame has a recess 14 to receive the bolt (not shown) from the conventional lock. A strike plate 16 is secured at the outer end of this recess. A bar 18 has a hook-like element 19 at its inner end and is referred to herein as the hook bar. The hook is received in recess 14 and the bar passes outwardly between members 10 and 12. It passes through an opening 20 in a locking device 21 which comprises a plurality of plates, including an inner plate 22 and an outer plate 24 and means for maintaining said. plates in spaced relation to form a slideway. These means are shown as constituting an intermediate or spacer plate 26, which has a partially cut-out section 29 to receive a locking plate 30 pivoted at 31 within the recess. Plates 22, 24 and 26 may be secured together in face-toface relation by any suitable means, such as welding or by means of rivets. The locking plate has a curved finger 32 which, when the plate has been rotated to locked position, engages one of a series of abutments on the hook bar. These abutments may be raised projections but these preferably are a series of spaced through slots or holes 34 forming bars whose opposed edges provide the abutments. The finger 32 passes through one of these through slots 34 in the hook bar and thus restrain movement of the locking device 21 on the hook bar when the parts are in locked position. The opposed walls of each slot 34 form these abutments and a greater safety factor is provided by having the finger of considerable length and thus pass completely through the hook bar. These abutments could be simply raised projections and no piercings. The outer plate 24 has a rectangular extension 36 at one end thereof, which is bent outwardly at right angles to the plate and this extension has an opening 38 therein. The pivoted locking plate also has a similar angular extension 40 with an opening 41 and when the parts are in locked position, these two angular extensions are in face-to-face relation and may be secured against relative movement by any suitable means, such as by the hasp 42 of padlock 43.

When the padlock has been removed from the locking assembly 21, the right angular extension 40 of the pivoted plate serves as a handle to rotate the plate downwardly to the position of FIG. 5 where a stop 45 between plates 22 and 24 engage an edge at the inner end of an arcuate slot 47. Rotation in the other direction is stopped when upper edge 49 contacts edge 50 of cut-out 29.

FIG. 6 shows the use of the lock of the present invention in securing a dresser drawer in locked position. The hook bar 18 is inserted below the usual filler strip 52 secured below the top 54, with the hook 19 extending upwardly. The drawer 56 is closed and the locking device applied to this hook bar as before.

What I claim is:

1. A portable auxiliary locking device for doors, drawers and the like which are mounted in frames, and including an elongated thin hook bar provided at its inner end with a laterally offset portion forming a hook to be received in an opening in one of the members to be locked relative to the other, said bar also being provided with a plurality of spaced abutments disposed longitudinally of the bar, a locking device carried on and perpendicular to the hook bar, said device having an opening shaped to receive the bar in close fitting but free sliding relation, and comprising a generally fiat housing formed from a plurality of superimposed plates including an inner plate of such size as to cover a portion of the door and the frame when the parts are in locked position, and an outer plate, and means for securing the plates in spaced relation to provide a recess between said plates, and a locking plate pivoted within said recess and rotatable between a locked and an unlocked position, and provided with a finger which engages one of said abutments when the plate is in the locked position, securing the locking device to the hook bar and also securing the locking device against said portions of the door and frame, said pivoted plate having a projection position outside the housing, and means for securing the pivoted plate in locked position with its finger engaging one of the abutments on the hook bar.

2. The structure of claim 1 wherein said last securing means includes said projection on the pivoted plate and a projection on the locking device in face-to-face relation with said first projection when the parts are in locked position, both projections having aligned openings to receive locking means.

3. The structure of claim 2 wherein the projections have a right angular relation to the plane of the pivoted plate and the locking device.

4. The structure of claim 3 wherein the locking means is a removable lock passing through said openings to secure the projections against relative movement.

5. The structure of claim 3 wherein said locking means is a padlock.

6. The structure of claim 1 wherein the hook bar has spaced through openings forming bars whose edges form the abutments engaged by the finger positioned within the opening.
