    Shut-off device for bicycles
    The invention relates to a shut-off device for bicycles in the form of a back support.
    Bicycles, especially those for mountain sports, should be as light as possible, so that a person using the bicycle when driving, especially when driving uphill, is physically relieved. As a result, the demands on the total weight of the bicycle are high. Any object that has to be carried along, such as a lock in the form of a bicycle lock, brings additional weight. In addition to the weight problem requires longer Bergauflfahren, due to the curved posture of the person using the bike, the back, and in particular the lumbar region, beyond measure. Common bicycle seats have the disadvantage that they offer the person using the bike no support in the lumbar region.
    US 4 948 020 A discloses a backrest that can be attached to a frame part of a bicycle. The orientation of the backrest is changeable, whereby it can also be used as Kotschützer or as a cover for the bicycle seat.
    It is the object of the present invention to provide an improved backrest.
    The invention solves this problem by a shut-off device in the form of a back support, which is detachably connected in a locked first state at a first end, which is guided through an opening of a wheel, with a seat post or a frame part, wherein a rotation of the wheel is blocked ,
    The shut-off device advantageously has at the first end blocking means, in particular a sleeve with lock function, on which shut-off means in the locked first state with the seat post or the frame part are detachably connected. Preferably, the blocking means are designed as a split, movably mounted sleeve with a device with lock function. As a result, the advantage is obtained that the shut-off fast, convenient and theft-proof attached to the bike, and also just as quickly and easily removed again.
    In a mobile second state, the Absperrvorriehtung when driving the bike, especially when driving uphill, advantageously be used as Rüekenstütze. For this purpose, the shut-off device is releasably connected to the seat post or the frame part at the first end, wherein one revolution of the wheel is released.
    The shut-off device in the form of a back support, in an advantageous embodiment, additionally has a massaging action. In this case, the shut-off device preferably has a back element at a second end, which is designed to deliver the massage function in the form of a massage effect. The back member supports the person operating the bicycle in the lumbar region and thereby facilitates the transmission of power to the pedals. In this case, in a particularly advantageous embodiment, the back element is ergonomically shaped such that it exerts the massaging effect on the lumbar region of the person operating the bicycle when the bicycle is being operated. Preferably, the back element has at least two, preferably padded, beads with a spacing of preferably 7 to 13 cm
    In a further advantageous embodiment, the back element is larger than the opening of the wheel. As a result, prevents the back element, that in an attempted theft of the bicycle in the locked-first state, the first end of the shut-off can be forcibly pulled out through the opening of the wheel.
    In an advantageous embodiment, the back element is arranged on the basis of positioning means, which are arranged between the first end and the second end of the blocking means, in the rear region of a bicycle saddle.
    In a particularly advantageous embodiment, the positioning means are designed as a double telescopic, that is variable in length, telescopic tube. As a result, the advantage is obtained that in the mobile second state, the distance of the back element to the spine of the lumbar region of the person using the bicycle and / or the position of the back element along the spine are adapted to be adapted to the telescope tube.
    Assign the positioning means, or the telescopic tube, advantageously additionally at least one telescopic joint, wherein the positioning means on the telescopic articulation are at least 180 degrees axially rotatable, the shut-off device in a movable third state, are aligned substantially parallel to the road plane, and so fulfill the function of a Kotschützers.
    The invention will now be described by way of non-limiting example with reference to the drawings. In the drawings show
    Figure 1 is a by means of a preferred embodiment of the invention the shut-off device in the form of a back support on a rod locked bike in side view.
    2 shows the shut-off device according to the invention in the form of a back support connected to a seat post in side view;
    Fig. 3 is a perspective view of a back element according to the invention.
    Fig. 1 shows in side view a road surface 11, on which a bicycle 2 stands, which is fixed by means of a shut-off device 1 according to the invention in the form of a back support releasably attached to a rod 12. Detachable here means that it can be solved by the rod 12 by means of a key which allows unlocking or locking a device with lock function 4. The device with lock function 4 is part of a split, preferably movably mounted sleeve 3, which has the shut-off device 1 at its first end la.
    Fig. 2 shows the shut-off device 1 according to the invention in the form of a back support connected to a seat post 8 of a bicycle seat 9 in side view. The shut-off device 1 has between the first end la and a second end Ib positioning means in the form of an angled telescopic tube 5, which is preferably on two telescopic joints 5a and 5b telescopically, that is changeable in its length, is. The telescopic joint 5 a is rotatable about an axis 5 c of the telescopic tube 5 by 180 degrees. At the second end Ib, the shut-off device 1 has a back element 6. The back element 6 is connected to the telescopic tube 5 via a fastening element 6a and is rotatable about the fastening element 6a in a plane which coincides with the plane of the drawing in FIG.
    The shut-off device 1 in the form of a back support can be aligned and locked in three states to be distinguished by means of the telescopic tube 5, wherein the shut-off device 1 fulfills a characteristic function in each of the three states: 1) In a locked first state, which is illustrated in FIG is, the shut-off device 1 is guided with the first end la through an opening, such as a Speichenöffhung, a wheel 7. The telescopic tube 5 is directed to the telescope 5 a and 5 b directed and locked in such a way that the shut-off device 1 at the first end la by means of a split, movably mounted sleeve 3 can be attached to the seat post 8. The telescopic tube 5 can be designed according to the disclosure of EP 0858761 A1.
    The sleeve 3 has a device with lock function 4, whereby the sleeve 3 can be closed against theft. One revolution of the wheel 7 is thus blocked by the fixed locking of the telescopic tube 5, and the shut-off device 1 serves as an immobilizer. In addition, it is advantageous that the back element 6 at the second end Ib of the shut-off device 1 is larger than the opening of the wheel 7, whereby a violent pulling out of the shut-off device 1 is prevented. Furthermore, the shut-off device 1 can be aligned and locked around a rod 12, whereby the bicycle 2 is additionally secured against theft by carrying or the like.
    By unlocking the device with lock function 4, loosening the sleeve 3 of the seat post 8 and pulling the shut-off device 1 from the opening of the wheel 7, the blocking of the rotation of the wheel 7 is released, and the bicycle 2 can be operated. The shut-off device 1 can be stowed, for example, in a backpack, or brought into one of the two other possible states. 2) In a mobile second state, which is shown in Fig. 2, the shut-off device 1 with the first end la is not guided through an opening of the wheel 7. The rotation of the wheel 7 is ff eigegeben. The telescopic tube 5 is connected to the
    Telescopic joints 5a and 5b aligned and locked so that the back member 6 is aligned in the rear region of the bicycle saddle 9 substantially perpendicular to the road surface 11. As a result, the support of a person operating the bicycle 2 in the lumbar region is made possible. The shut-off device 1 is attached to the seat post 8 of the Eahrradsitzes 9 at the first end la by means of the split, movably mounted sleeve 3.
    The back member 6, which is additionally shown in Fig. 3, can be rotated about a fastener 6 a, so as to allow a better adaptation to the seating position of the bicycle 2 serving person. In addition, the distance of the back element 6 to the spine of the lumbar region of the person operating the bicycle 2 can be adjusted by adjusting the length of the telescopic tube 5 on the telescopic joint 5a and / or the position of the back element 6 along the spine by means of a length adjustment of the telescopic tube 5 on the telescopic joint 5b. Hierdureh the back member 6 can be particularly ergonomically matched to the seating position of the person operating the bicycle 2, whereby a particularly good support during cycling, especially when mountain climbing, is given.
    The shut-off device 1 in the form of a back support preferably additionally has a massage function. This is exercised by a massage action of the back member 6 on the lumbar region of the bicycle 2 serving person. For this purpose, the back element 6 is advantageously made upholstered and has two, likewise padded, beads 13. These beads 13 are formed at a distance A as parts of the back member 6. The distance A is selected in such a way that the beads 13 act on both sides, along the spinal column of the lumbar region of the person operating the bicycle 2. Preferably, the distance A is seven to thirteen centimeters. Due to the inventive shape of the beads 13, these attack along the spine in the lumbar region on the basis of four pressure points 14, which improves the massage effect in terms of well-being and positive health effect. 3) In a third wheeled state not shown in the figures, the shut-off device 1 with the first end 1a is not guided through an opening of the wheel 7. The rotation of the wheel 7 is ff eigegeben. The telescopic tube 5 is articulated to the telescope 5 a and 5 b aligned and locked so that the back member 6 is aligned in a plane substantially parallel to the plane 11 plane above the wheel 7. The alignment of the telescopic tube 5 in this case requires a rotation of the telescopic tube 5 on the telescopic joint 5 a by 180 degrees about an axis 5 c. Here, a telescopic tube according to the Offenbamng EP0858761 Al developed accordingly.
    The shut-off device 1 is fastened to the seat post 8 of the bicycle seat 9 at the first end 1a by means of the split, movably mounted sleeve 3. In this orientation, the shut-off device 1 in the form of a back support fulfills the function of a Kotschützers. The person operating the bicycle 2 is thus protected from dirt and moisture thrown from the reversing wheel 7 in the direction of the back. To improve this function, a corresponding Kotschützeraufsatz can be attached to the telescopic tube 5.
    It may further be mentioned that the shut-off device 1 according to the invention in the form of a back support can also be used as a luggage carrier. The shape of the back element 6 can hereby optionally be adapted. The massage effect of the back element 6 can also be caused, for example, by electrical massage means. The execution of the shut-off means may deviate from the sleeve 3, for example, this may be an injection molded part made of plastic or degradable plastic, which is releasably secured, for example by means of a thumbscrew or a quick release. The device with lock function 4 can be switched off and unlocked by means of a key or a combination of numbers. Likewise, the device with lock function 4 can be activated electronically by means of a fingerprint or by mobile telephone by means of wireless communication such as RFID or NFC.
    The shut-off device 1 according to the invention in the form of a back support is advantageously made of lightweight materials such as plastic, degradable plastic, wood, aluminum, magnesium, titanium, sheet steel, foamed steel or other foamed metal, carbon, or composite materials such as GRP or WPC. The back element 6 is weather-resistant coated, for example, with leather, synthetic leather, or a water-repellent textile made of natural or synthetic fibers.
    Furthermore, the shut-off device 1 according to the invention can also be used on mopeds, scooters, motorcycles or such vehicles, or on seating furniture.
