Description

The invention relates to a padlock, consisting from a lock case body as well a lock bracket, which with its temple ends of recesses in the lock case body being a first temple end a return to block a bow movement in the closed state and a second temple end has a groove for limiting the movement of the bracket in the open state, according to the preamble of claim 1.

Padlocks in different designs with different locking systems are state of the art.

Known padlocks are special adapted Profile cylinder used. For transmission the rotation of the key are a large number of specially manufactured locking elements necessary. From this fact the necessity arises separate production as well as cost-intensive storage of the required variety of parts.

There are basically manufacturer-specific ones Solutions, so that a defective lock cylinder one Manufacturer by a locking cylinder from another manufacturer can be replaced. This means that there is no compatibility is what is ultimately a disadvantage for the end customer or customer represents.

As is known, the dimensions of locking cylinders correspond or half-lock cylinders for mortise locks or similar locking the German industry standard DIN 18252. This standard concerns under other external dimensions of such locking cylinders, which, in principle, are interchangeable with correspondingly standardized production are. When changing ownership, e.g. an apartment can therefore in simple way against a lock cylinder a new cylinder can be replaced without replacing the entire lock or to disassemble.

It is from the foregoing, therefore Object of the invention, a further developed padlock, consisting from a lock case body as well to specify a lock bracket being the actual locking mechanism realized in a particularly simple manner using standard components should be so that the cost of both manufacturing and warehousing of padlocks or Lock case bodies reduced and above also the possibility consists of integrating padlocks into locking system systems without special components.

The solution to the problem of the invention done with a padlock, consisting of a lock case body, according to the characteristics according to claim 1, wherein the subclaims at least useful embodiments and represent further training.

Basically, a padlock consists of one Lock case body as well a lock bracket, which with its temple ends of recesses in the lock case body and with a first temple end a return or a franking to block a bow movement in the closed state having. A second temple end of the lock bracket a groove to limit the movement of the bracket in the open state, i.e. in vertical Direction.

According to the invention is now on the opposite side of the lock bracket Floor area of the lock case body one parallel to the ends of the bow oriented, inward-extending recess for complete reception a standard half-lock cylinder intended. The lock beard a standard half-lock cylinder then inserted engages in the closed position in the return or the franking at the first temple end, being the width of the recess the lock bit width essentially corresponds.

Through this defined recess to accommodate the standard half-lock cylinder, it is possible to use a such usual Standard component in the lock case body without further locking elements use and to achieve a safe guard locking.

In other words, serves as a closure element the lock beard of the standard half-lock cylinder used and it will be in In contrast to known padlocks, no additional ones closure elements necessary.

The lock bracket is with the associated hole in the lock case body like this voted that at push in of the lock bracket the Postage exactly at the height of the lock bit stands. When closing of the standard half-lock cylinder becomes the lock beard in the clearing of the temple swung in and remains in this position after key removal. So that's the bracket veriegelt.

Becomes the standard half-lock cylinder unlocked, the locking bar swivels out the release of the temple and the temple is released in this way, which then through one in the housing located compression spring, in particular helical compression spring, is pressed out of the lock case body.

One in the inner end of the recess for the Standard half-locking cylinder bracket locking pin located in a groove prevents it from stepping out completely of the lock bracket, respectively the second temple end, which has a groove for limiting the movement of the bracket in the open state.

The recess in the lock case body is preferably so realized that the Transverse axis of the standard half-lock cylinder essentially diagonally with respect to the cross-sectional area of the Lock case body runs.

As mentioned above, the length of the temples is designed with locking recess so that when the bracket is pressed in, the locking recess or the clearance is located at the height of the locking bar.

The recess for the temple ends, especially for the second Ironing end is realized as a hole in the bottom area of which the helical compression spring is located.

There is also a hole in the lock case body for a common fastening screw, especially stud, for the standard half-lock cylinder available.

The side edges of the lock case body point a chamfer, the top of the box body being designed as an inclined surface is so that at an attempted use of force is not a tool or only with big ones Disadvantages can be applied and thereby improved Properties of such a padlock result.

The bow pin is a straight pin preferably formed, which with its second bracket end pointing side into a circumferential side provided there Engages groove, which allows the bracket to be freely rotated or pivoted, however, a complete one Step out of the bracket is prevented from the lock case body.

With the standard half-lock cylinder removed Solving the Fastening screw or the stud screw and swiveling out the mustache from clearing the temple by means of a closing movement of the key is the preferably cylindrical bow pin removable so that on this way complete assembly by removing the lock bracket and the helical compression spring can be effected. In the opposite sense can the padlock in can be easily assembled.

The fact that that this padlock according to the invention only from a few, essentially two parts, namely the lock case with profile cylinder opening and the actual padlock bracket. As an accessory is the View helical compression spring, which the lock bracket when unlocking the half-lock cylinder to be used pushes.

As usual, both the special lock case body and also a preassembled variant consisting of the lock case body, lock bracket, helical compression spring and Ironing safety pin his.

The invention is based on the following of an embodiment as well as explained with the help of figures.

Here show:

1 a schematic diagram of the padlock according to the invention in the closed state and

2 two perspective representations of the padlock with recognizable inclined surfaces on the lock case body.

The padlock according to the embodiment consists of a lock case body 1 or a metallic housing body.

Furthermore is a lock bracket 2 provided which with its temple ends from the lock case body 1 is recorded. A first temple end 3 has a return or franking 4 to block a shackle movement in the closed state and a second shackle end 5 a groove 6 to limit the movement of the bracket 2 in the open state.

Im on the lock bracket 2 opposite bottom area of the lock case body 1 is one parallel to the temple ends 3 . 4 Oriented, inwardly extending recess for the complete reception of a standard half-lock cylinder 7 brought in, the lock bit 8th in the return 4 engages in the closed position.

The width of the return 4 or the formation of this corresponds essentially to the dimensions of the lock bit 8th ,

As shown in the illustration below 2 removable, the transverse axis of the standard half-lock cylinder runs 7 essentially diagonally with respect to the cross-sectional area of the lock case body 1 ,

The length of the temple ends 3 and 5 is designed so that when the bracket is pressed in 2 the blocking return 4 or the franking in the amount of the lock bit 8th of the standard half-lock cylinder 7 is located.

The recess for the second temple end 5 is a hole in the bottom area 9 a helical compression spring 10 is located.

In the inner end of the recess for the standard half-lock cylinder 7 is a groove for a locking pin 11 formed, the groove being substantially perpendicular to the second bracket end 5 extends.

Furthermore is in the lock case body 1 a hole for a fastening screw 12 of the standard half-lock cylinder 7 intended.

The side edges 13 of the lock case body 1 have a chamfer, whereby according to 2 the top 14 and two side faces 15 of the lock case body 1 are designed as an inclined surface, so that a tool that may be attached during the attempted break-in slides off, thereby increasing security when using the padlock.

The quasi diagonal position of the standard half-lock cylinder 7 in the lock case body 1 enables optimal space utilization with minimized overall dimensions of the box body itself. By loosening the fastening screw 12 and the pivoting of the lock bit from the clearing of the bracket by means of the closing movement of the key can the standard half-lock cylinder 7 easily replaced and replaced.

The lock case body with lock bracket is easy to keep in stock and can then be combined with a standard half-lock cylinder to form a finished product, depending on customer requirements.
