Abstract

A hoop lock includes a lock body, which includes a housing and a locking apparatus accommodated in the housing, and a closing hoop that has at least one end that can be selectively locked to the lock body or released from the lock body by way of the locking apparatus. An armoring is applied to the closing hoop and/or the housing of the lock body by way of buildup welding.

Claims (43)

1 . A hoop lock comprising:

a lock body that comprises a housing and a locking apparatus accommodated in the housing; and

a closing hoop that has at least one end that is selectively locked to the lock body or released from the lock body by way of the locking apparatus,

wherein an armoring is applied to at least one of the closing hoop and the housing of the lock body by way of buildup welding;

wherein the armoring comprises a hard metal.

2 . The hoop lock in accordance with claim 1 ,

wherein the armoring is formed in the form of at least one armor bead.

3 . The hoop lock in accordance with claim 2 ,

wherein the armor bead has a width between 5 mm and 10 mm.

4 . The hoop lock in accordance with claim 2 ,

wherein the armor bead extends over at least approximately the total length of the housing and/or over at least approximately the total length of the closing hoop.

5 . The hoop lock in accordance with claim 2 ,

wherein the armor bead is a continuous armor bead.

6 . The hoop lock in accordance with claim 2 ,

wherein the at least one armor bead has a thickness between 0.5 and 5 mm.

7 . The hoop lock in accordance with claim 2 ,

wherein the armor bead is formed by a plurality of segments spaced apart from one another.

8 . The hoop lock in accordance with claim 1 ,

wherein the armoring is formed at at least one of a side surface and an edge of the housing ( 14 ).

9 . The hoop lock in accordance with claim 7 ,

wherein the armoring is formed at an outer side surface of the housing.

10 . The hoop lock in accordance with claim 8 ,

wherein the armoring is formed at an outer edge of the housing.

11 . The hoop lock in accordance with claim 1 ,

wherein the armoring is formed centrally at at least one side surface of the housing, at at least one side surface of the housing offset from its center, in the region of at least one edge of the housing, and/or partly or completely at at least one edge of the housing.

12 . The hoop lock in accordance with claim 1 ,

wherein at least two side surfaces of the housing and/or at least two side surfaces of the closing hoop are provided with an armoring.

13 . The hoop lock in accordance with claim 12 ,

wherein at least two oppositely disposed side surfaces of the housing are provided with an armoring.

14 . The hoop lock in accordance with claim 1 ,

wherein the armoring is formed in a depression provided at a side surface of the housing.

15 . The hoop lock in accordance with claim 1 ,

wherein the closing hoop is formed by a plurality of jointed bars connected to one another in an articulated manner and the armoring is formed at at least one of the jointed bars.

16 . The hoop lock in accordance with claim 15 ,

wherein the armoring is formed at a narrow side of the jointed bar.

17 . The hoop lock in accordance with claim 15 ,

wherein the armoring is formed in a depression provided at a side surface of the jointed bar.

18 . The hoop lock in accordance with claim 1 ,

wherein the armoring is formed at at least one of a side surface and an edge of the closing hoop.

19 . The hoop lock in accordance with claim 18 ,

wherein the armoring is formed at an outer side surface of the closing hoop.

20 . The hoop lock in accordance with claim 18 ,

wherein the armoring is formed at an outer edge of the closing hoop.
