Abstract

Locking devices for a variety of security purposes utilize a commercially available padlock of rectangular configuration having a sliding bolt (73) which bridges a recess in one side face of the padlock. A housing for this type of padlock is formed on or secured to a hasp (61) or other component which is to be locked to a staple (62). The housing has two wall portions (3, 64) and a foot portion (4) corresponding to the two main flat faces and the recessed side face of the padlock, and the padlock is a sliding fit in the housing. There is a slot (72) for entry of the staple (62) into the recess in the padlock. A guard plate (6) partly closes one end of the housing, in line with the bolt (73).

Locking devices are described for locking shutters and doors, particularly on commercial vehicles, and for locking security posts for blocking driveways or roadways.

In a twisting-rod housing mechanism for commercial vehicle doors, the padlock housing (1) is secured vertically to a twistable rod and the staple (226) is mounted so that it is horizontally slidable into and out of the slot in the housing.

Claims

1. A locking device comprising a staple and another component to be locked to the staple, wherein a metal padlock housing is formed on or secured to said other component, the housing being dimensioned to receive and shield a sliding-bolt padlock of rectangular configuration having two main flat faces and a side face which has a recess across which the bolt slides, said housing having two wall portions and a foot portion corresponding respectively to said two main faces and said side face of the padlock, the two wall portions being separated by a distance which is marginally greater than the depth of the padlock separating the two main flat faces, so that the padlock is a sliding fit between the said wall portions, said housing also having a slot for entry of the staple into the recess in the padlock to engage the bolt.

2. A locking device according to claim 1, wherein a guard plate is provided at one end of the housing to bridge said wall portions adjacent to said foot portion.

3. A locking device according to claim 1 wherein the housing has a bridge portion between the wall portions at the edges thereof remote from the foot portion.

4. A locking device according to claim 1 wherein the staple has a slide-mounting which permits the staple to slide into and out of the slot in the housing.

5. A locking device according to claim 1 wherein the component to be locked to the staple is a hasp.

6. A locking device according to claim 5 wherein at least part of the hasp forms one of the portions of the housing.

7. A locking device according to claim 1 wherein the component to be locked to the staple is a twistable rod in a twisting-rod locking mechanism.

8. A locking device according to claim 7 wherein the padlock housing is secured to a vertical rod with the two wall portions of the housing arranged vertically, the slot being on the side of the housing remote from the rod.

9. A locking device according to claim 1 wherein the housing is secured to a security post and the staple is formed by an arm hinged to a base tube adjacent to the mouth thereof into which the post fits, a plate fixed to the arm being adapted to be swivelled with the arm between a covering position in which it covers the mouth of the base tube and an upright position in which it stands beside the housing so that part of the arm enters the slot in the housing, an aperture being provided in said part of the arm to engage the bolt of the padlock.

10. A locking device according to claim 1 for locking an assembly of two overlapping elements, wherein the staple is secured to one of the said elements and the padlock housing is secured to a rigid rod or bar which can be passed through the two elements in the overlapping region to prevent relative movement between the two elements.

11. A locking device comprising:

(a) a sliding-bolt padlock of rectangular configuration having two main flat faces and a side face which has a recess across which the bolt slides;

(b) a staple adapted to be secured to a first object; and

(c) a metal padlock housing adapted to be secured to a second object which is to be padlocked to the first object, said metal padlock housing having two wall portions and a foot portion, said two wall portions being separated by a distance which is marginally greater than the depth of said sliding-bolt padlock separating the two main faces of said sliding-bolt padlock, whereby said sliding-bolt padlock fits slidingly between said two wall portions, said metal padlock housing having a slot sized, shaped, and positioned so that said staple can pass through said slot and engage said bolt.
