dLscloses a lock arrangement for a container comprising a ~;'?~ bar. The arrangement is provided with fixing means inserted in~éhe openiDgs of the braces on the edges of the container. ;`
The~arrangement is provided with a lock handle connected 20~:with~on-~of the fixing means and rotatable therein. In its ~ locked position the lock handle is enclosed by a protective Sbi~ shield.~The object of this shield is to reduce the!risk, of ~.
the lock~belng forced open. The protective shield is, how-ever~, uneatisfactory, as a burglar with suitable equipment 25~ is e~asily able to reach the vital parts, especially the shackle of the padlock. Furthermore it is disadvantageous that the entire lock arrangement has to be removed for . , obtaining access to the container. Moreover, the arrangement is very heavy and difficult to handle. It can also be used for different containers, since it is not especially adapted ~
to one container. ~ `
US patent specification no. 4.500.123 discloses a door ; ;~
lock arrangement for e.g. the back door of a truck or a -van. The lock arrangement comprises two tube-shaped parts, each fastened to one half o f a double door. The end of one - .: .:;: :. .
tube-shaped part is provided with a box-shaped part. When lO the lock is to be shut, a long tube is inserted in the two -tube-shaped parts, the length of said tube corresponding to the total lengeh of the two tube-shaped parts. The long ;~
~, tube is provided with a plate fitting in a groove in the ~;~box-shaped part. The plate has a hole through which the 15 shackle of a padlock is insertable. When the lock is to be shut and tha plate is positioned in the groove of the box-shaped part, the padlock is inserted in the box-shaped part and~ locksd. The padlock is now positioned inside the box-sbaped~part and thus protected against cutting-off and other 20~ways~ of being forced open. Furthermore the inside of the long tube is provided with a freely rotatable inner tube.
; ;, The obj,ect of the inner tube is to render it more difficult to cut through the long tube. The disadvantage~of this door lock~ ar~rangement lies in the padlock not being tightly 25 ~enclosed by the box-shaped part, and the long tube having to bs removed en~irely from the lock arrangement before the opening of the door. The remaining parts are, however, ;: " ~. :, =~
1 3 3 2 1 ~ 2 permanently mounted on the door. A further disadvantage is that although they are secured, the heads of the bolts are accessible from outside, e.g. for a crowbar or the like.
The ob;ect of the invention is to provide a lock 5 arrangement of the above type not only reducing the above disadvantages but also ~nsuring a considerably improved protection against burglary.
SummarY of the Invention According to the invention, when the lock arrangement 10 is shut, the lock members are inside a housin~ mounted on the crossbar or the counterpart, said housing being shaped and arranged in such a way that it tightly encloses the padlock and the lock members, when the padlock provided with a straLght shackle is in its locked position, and the 15 housing and the lock members are furthermore provided such that~the padlock is insertable in the housing via an opening th~erein by a rectilinear movement in ae least two directions p;erpendicular to each other, and the crossbar and the coun~terpart~are fastoned to the container by means of safety ;;ZO~f~astening means, such as bolts, the heads of which being on the same level as the crossbar and/or the counterpart. Since the lock members and the shackle of the padlock arq tightly enolosed by the housing when the lock arrangement Ls shut, it is virtually impossible to obtain access to these vital 25iparts~ by e.g. a saw or a crowbar. When the fastening means are secured a burglar is not tempted to try to force the lock : . .
j~ arrangement by removing said fastening means. All part are ~ ~
'' ~-',:
1 3 3 2 1 1 2 ~ ~
fastened to the container, thus avoiding various forms of loose rods. A further advantage of the inventive arrangement is that all parts are permanently connected with the container, and only the lock itself is removable when the 5 lock arrangement is not in use.
According to the invention the housing is box-shaped and completely closed off at four of the six sides, partly closed off on the fifth side and open on the sixth side.
Consequently the lock is accessible only from one side, 10 rendering it difficult for a burglar to obtain access to the vital parts of the lock by means of various tools.
In a preferred embodiment of the inventive lock arrange-ment the lock member in the housing is fastened to two of the sides of the housing and to an edge of the fifth side.
15 This results in a substantial part of the padlock being situated inside the housing and thus completely inaccessible when the padlock is in its locked position.
In a further preferred embodiment of the inventive lock arrangement the lock member mounted in the housing ; 20 forms a chamber therein, said chamber being closed off on five sides, apart from the hole in the lock member, while the sixth side of the chamber is open, thus increasing,the ~; inaccessibility.
According to the invention it is advantageous that 25 the first insertion direction of the padlock is parallel to ~; but not coinciding with the axis of the hole through the lock members.

The inventive lock members are made of thick plate-shaped blanks, and the total thickness of the blanks is slightly less than the largest width the psdlock is able to bridge. This renders it very difficult to twist the lock 5 apart.
In yet another preferred embodiment of the invention the fastening means include bolts retainable during the lock arrangement being mounted on the container, e.g. by means of the bolt having a hexagonal socket at the end 10 opposite the head. As a result it is impossible to get a grip on the heads of the bolts from outside by using various types of tools. ~ ;
In a further embodiment of the invention the fastening - means in form of bolts are secured against cutting of by 15 means of sleeves arranged around the shanks of the bolts, .
and that the sleeves are freely rotatable, although the balts are secured, and that the sleeves are countersunk in the~spac-rs, and the counterpart is an integral part of the spacers. ~hen a person attempts to cut through the shank of 20~the bol;t by -ither cutting down between the parts of the lock arrangement or by cutting said parts off, the sleeve only rotat-s, thus preventing cutting-off of the bdlts.~
In another embodiment of the invention the sleeves are of hardened steel or of sintered hard metal. Thus the 25 bolts are manufactured from inexpensive materials, while .:
the sleeves are extremely hard. Small round articles of ~-even thickness are easily manufactured from extremely hard . ~, ' ', '~
