CLASS 63: Saddlery, wagon construction and bicycles.

Addendum to patent JU 90836 from September 1, 1896.

Patented in the German Empire on April 22, 1897. Longest duration: August 31, 1911.

The present invention is an improvement on the bicycle lock protected by Patent No. 90836. The new lock is set up in such a way that, in contrast to the main patent, the bolt reaching between the wheel spokes is brought into the locked position without depressing the handle d and, to secure the locked position, the lock activated by a key is no longer against the bearings of the lock rod c moves, but for this purpose a manually depressed bolt is arranged, which only requires the use of a key to trigger it.

Another advantage over the main patent No. 90836 is that the bolt, which is pressed down by the handle d and engages between the spokes, is automatically moved by the specially mounted spring from the closed position into the position permitting the movement of the wheel.

On the accompanying drawing, this innovation is shown in Figs. 1 and 2 in side and front view. Fig. 3 is also a side view and Fig. 4 is a plan view.

The eye a ¹ formed on the clamp α for receiving the rod c carrying the handle d has the recess k directed towards the front and the recess k ¹ on the side in the extension a ³ . The recess k is provided on one side with a wedge surface, which corresponds to that at the extension i of the bolt /, so that when the rod c is rotated by the handle d by virtue of the two wedge surfaces sliding on each other, the bolt / is automatically pressed down leave the recess k and snap into the recess k ¹ according to the closed position by the pressure of the spiral spring 0.

Since the recess k ^{1 has} no wedge surface, the bolt Z is released from this recess by depressing the handle d.

The coil spring ο engages with its upper end in the part of the bolt Z fastened to the rod c , while the lower end of the same is fastened in the bearing a ² connected to the clamp α.

When the bolt Z is turned into the closed position, the spring ο is tensioned in such a way that when the bolt is released from the recess k ^l, the spring ο moves back into its rest position and thereby takes the bolt / with it, so that it goes back into the recess k snaps into place.

To secure the locked position of the bolt Z, a lock / is attached to the rod c , the bolt e ^{1 of} which is provided with the handle e and is pressed against the eye a ^{1 by} means of the hand. The remains in this position

Bolt e ¹ are fixed by the mechanism of any construction located in the Schlofs_ /, which can only be triggered by a suitable key, so that it is impossible to depress the handle d and consequently to release the bicycle by turning the bolt Z.

Claims (1)

Patent Claims: i. An embodiment of the bicycle lock protected under No. 90836, in which the bolt by turning the handle (d) by 90 ° by virtue of the wedge surfaces of a bolt attachment (i) and a recess (k) sliding on each other leaves the latter and in the position of use, engaging in a recess (k ¹ ) , which with its upper end in the bolt (I) and with its lower end in the bearing (a?) tensions the spiral spring (o) in such a way that after the bolt has been pushed out of the recess (k ^l ) by means of the handle (d) the spring (o) moves the bolt (I) back into its position releasing the wheel. An embodiment of the under 1. ge. marked bicycle lock, in which a lock (f ) preventing the release of the locking bolt (I) is arranged in such a way that a bolt (e ¹ ) located in the same prevents the depression of the rod (c) and is depressed by means of the handle (e) is held in place by a mechanism which only allows the bolt (e ¹ ) to return after using a key. 1 sheet of drawings.
