while driving.

Patented in the German Empire on July 18, 1897.

According to the present invention, the saddle of a two-wheeler or other bicycle is so arranged to move it from its normal height to one for mounting the bike can be brought down in a comfortable position and held in this position until the Cyclist has climbed up and achieved balance. The seat can then be locked again in its position suitable for driving.

For this purpose the saddle or the seat post or any other one becomes more suitable Part of the machine which carries the saddle, so arranged that it is in a suitable manner against the effect of a resilient body, which is used to restore the saddle afterwards can be lifted, pushed down, and is a suitable and easy-to-use locking device provided to; to release the saddle and push it down slightly can, whereupon it is later automatically determined in the high position.

In the accompanying drawings shows:

Fig. Ι partly in cross-section and partly in side view the design of a bicycle saddle carrier according to the present invention.

FIG. 2 is a longitudinal section along line xx in FIG. 1.

In Figs. 1 and 2, 1 is a saddle carrier or a seat post which can have any suitable shape at its upper end, such as, for. B. approximately T-, L- or similar shape, and on which a bicycle saddle 2 (drawn in dotted lines) is easy to attach. The support is attached in such a way that it slides in a tube 3 with its end resting on a spring 4. The same is prevented from rotating in the tube by a pin 5, which is firmly attached to the tube and ^{is guided in longitudinal recesses 5 a of} the support. Tube 3 has such a shape that it adapts to the seat post frame tube (drawn in dash-dotted lines) of a two-wheeler or other bicycle, can be inserted with its end into it and fixed in its position by a set screw, as is the case with the usual seat posts Case was. At its upper end, tube 3 has a pair of lugs 7, between which an eccentric locking device is rotatably mounted at 8; this allows the saddle stand to go up under the action of the spring 4, but prevents it from going down, except around the small piece which is necessary in order to automatically bring the device into operation. In the example shown in the figure, this device consists of a plate 9, the surface of which is shaped at 9 / eccentric to the center of movement 8, provided with teeth, made rough or notched and literally against a toothed, roughed or notched one

notched surface i ^a on the opposite side of the saddle stand ι is pressed by one or more matching springs io. The plate 9 also has a tooth or projection 9 ^b, which is arranged so, that the same in a sufficiently pressed down position of the seat frame 1 in engagement with a suitably shaped projection or a ^b i of a series of projections of the seat post is placed, and thereby the support holds down. The device is such that after pressing the outer end 9 ° • of the eccentric adjusting device 9 against the action of the spring 10, the saddle is depressed from its normal position against the action of the spring 4 into a position suitable for climbing the bike, in which the tooth or projection 9 ^{b of} the locking device can engage with one of the projections i ^{b of} the seat post 1 and automatically holds this post and thus also the saddle in the depressed position until the bicycle is mounted. If this is done, the weight of the cyclist will depress the seat post by a small amount, whereby the spring 10 automatically ^{withdraws the tooth or projection 9 b} from the seat post and ^{praises the eccentric surface 9 a} against the same. When the cyclist then picks up his weight on the saddle to a certain extent, the spring 4 pushes the seat post upward beyond the locking device, the eccentric surface 9 ^{a of} which allows the seat post to move upward. However, the surface 9 ^a comes into effect automatically after a slight downward movement of the seat post and keeps the saddle and the post in the raised position.

If the weight on the saddle is lifted only a little and instantly, so will the saddles go up in intervals or jerkily and come to a certain extent Increase time just a little. But if you put all the weight on the saddle cancels by z. B. on the cranks, the seat will move in one movement up to its full height.

Appropriate tools can be provided to help determine the height, up to which the saddle can rise to serve various needs. In which The example shown in the figure is the seat post ι. for this purpose with a with Screw-threaded rod 11 which passes through the bottom of the tube 3 goes through and is provided with a matching nut 12, which against the bottoms of the Tube and limits the degree of upward movement of the seat post without doing so to prevent their downward movement.

Claims (2)

Patent Claims: ι. A device for locking the bicycle saddle in a low position and lifting it the same during the journey, characterized in that the seat post is in The locking device holding the deep position by slightly further depressing it of the saddle is released for the purpose of lifting the saddle automatically after getting on by a spring acting in a known manner on the support. 2. An embodiment of the device identified under 1., in which the saddle is fixed in the lowest position by a ^{tooth (9 b ) acting against ratchet teeth (i b} ) of the seat post of a rotatable disk (9) under spring action, which tooth when pressure is applied to the saddle, it is lifted freely and by the rotation of the disc under the action of a spring, whereupon other teeth (9 ^a ) of the disc, which allow the saddle to rise but prevent it from falling, engage in ratchet teeth (i ^a ) of the seat post.
