Locking bars

Abstract

.[.A locking bar adapted to cooperate with a shackle of a padlock, which locking bar comprises a shackle-receiving orifice and an abutment provided on the surface of said bar, the arrangement being such that with the padlock secured to the bar by means of a padlock shackle passing through said orifice, the abutment is adapted to engage with the body and/or shackle of the padlock to restrain substantial rotation of said padlock about the orifice in said bar..]. .Iadd.An improved padlock construction having a body defining an upper surface and a bottom surface. Access to a locking mechanism is provided through the bottom surface, while the top surface is designed so that the body can receive a shackle and portions of locking bars in locking engagement. To achieve this purpose a cruciform-shaped depression is provided in the top surface, which depression extends downwardly into the padlock body. The depression comprises a first area adapted to receive dependent leg portions of the shackle and a second area transverse to and intersecting the first area for receiving the perforated ends of the locking bars. The portion of the body of the padlock defining the recess is designed so that when the shackle and locking bars are in a locking engagement, the shackle is substantially completely accommodated within said depression in an inaccessible position..Iaddend.

We claim: .[. 
     
       1.  An improved lock construction comprising a main body portion, a top wall portion arranged for introduction of a staple therewithin, front and rear wall portions, a bottom wall portion including a locking mechanism extending internally thereof and actuatable from without, and adapted for releasable interengagement with the staple to maintain said staple in a locking position, said top wall also including a cruciform-shaped depression extending downwardly toward the main body portion and terminating in a perforated shelf area, the cruciform-shaped depression comprising a first area adapted to receive dependent leg portions of the staple and a second area intersecting said first area for entry of perforated locking bars including a portion to be secured to said lock by said staple, said top wall portion including a forwardly projecting stepped portion arranged to extend beyond and overhand a limited area of the front wall, said stepped portion further including a terminus..]. .[.2. An improved padlock construction comprising a padlock body including a first body portion having a surface arranged for introduction of a staple therewithin, a second body portion including a locking mechanism extending internally thereof and actuatable from without and adapted for releasable interengagement with the staple to maintain said staple in a locking position, a cruciform depression extending through the surface of said first body portion towards said second body portion, said cruciform depression comprising a first area adapted to receive dependent leg portions of the staple, a second area intersecting said first area for entry of perforated locking bars including a portion to be secured to said padlock by said staple, first shielding portions in outwardly covering relation to opposite ends of said first area, a second shielding portion in covering relation to one end of said second area, said shielding portions forming an uninterrupted protective shield for one end of said second area and for each end of said first area..]. .[.3. A padlock as claimed in claim 2, in which the first body portion is made of laminated plates and the shielding portions are integral parts of said laminated 
     
     
        plates..]. .[.4.  A padlock as claimed in claim 3, in which the first and second body portions are part of a unitary structure which is not separable during ordinary use of the device..]. .[.5. A padlock construction as claimed in claim 2, in which said shielding portions form a unitary part of said first body portion, and the top surface of said body portion with said shielding portions is a single plane located at a point not substantially lower than the top of said staple when assembled with the padlock body, said top surface being continuous except for the cruciform depression..]. .[.6. A padlock construction as claimed in claim 5, in which said first and second body portions form a unitary structure which cannot be separated in ordinary use of the device..]. .[.7. An improved lock construction as claimed in claim 1 wherein the shelf area lies in a plane substantially coextensive with the terminus of said stepped portion..]. .Iadd. 8. An improved padlock construction for securing perforated locking bars, said padlock construction comprising a U-shaped shackle and a padlock body, said padlock body including a first end portion having an end surface thereof arranged for the introduction of the U-shaped shackle therewithin, a second end portion including a locking mechanism, extending internally thereof and actuatable from an end surface of said second end portion, for releasable interengagement with the shackle to maintain said shackle in a locking position, said body further including a cruciform depression extending inwardly from the end surface of said first end portion towards said second end portion, the side walls of said padlock body closing the ends of three arms of said cruciform depression and the fourth arm of said cruciform depression being open on one side of the padlock body, the first and second closed arms of the cruciform depression receiving the legs of the U-shaped shackle and substantially completely accommodating the U-shaped shackle when the shackle is in said locking position, and the third closed arm of the cruciform depression and the fourth open arm of the cruciform depression receiving the perforated locking bars to be secured together by the shackle of the padlock so that, in use, the perforated locking bars project through the side wall of the padlock and extent into the third and fourth arms of the cruciform depression. .Iaddend..Iadd. 9. An improved padlock construction as claimed in claim 8 wherein the sizes of said third and fourth arms of said cruciform depression in relation to the locking bars are such that, in use, the portions of the locking bars received therein substantially fill said third and fourth arms, the padlock body, in use, being disposed relative to the locking bars such that when the locking bars lie in vertical planes the padlock body is positioned beneath the locking bars. .Iaddend.
