BICYCLE STAND

Abstract: A bicycle stand comprising a swivelling axis in the transverse direction of the bicycle tyre, around which axis the bicycle tyre (9) pivots when it is placed in the bicycle stand (1). When pivoting around the swivelling axis, the bicycle tyre (9) has an effect on means that are arranged to render the catch (7) into a locking position when the bicycle tyre (9) is in the bicycle stand (1). The catch (7) opens only when the bicycle tyre (9) is pivoted around the swivelling axis. By locking the bicycle tyre (9) with a bicycle lock, the pivoting of the tyre (9) around the swivelling axis is prevented, whereby the catch (7) will stay in the locking position.

Description: Bicycle stand The present invention relates to a bicycle stand comprising a frame and supporting elements on both sides of a bicycle tyre for supporting a bicycle and for retaining it in the vertical direction, whereby the bicycle tyre can be pushed between the supporting elements and pulled therefrom, and that the bicycle stand comprises a swivelling axis in the transverse direction with respect to the bicycle tyre, a catch that is on top of the tyre when the tyre is in the bicycle stand in such a manner that the tyre cannot be lifted off the bicycle stand, closing means for moving the catch and a guide for guiding the catch on the tyre and off the tyre, whereby the closing means are arranged to pivot around the swivelling axis and to move together with the guide the catch into a locking position when the bicycle tyre pivots with respect to the swivelling axis when pushing the bicycle into the bicycle stand and correspondingly, to move the catch into an open position when the bicycle tyre pivots with respect to the swivelling axis when removing the bicycle from the bicycle stand. An ordinary bicycle stand, which comprises supporting arches secured to the frame of the stand in such a manner that the bicycle tyre rests on the supporting arches, does not provide any security against thefts. A bicycle in the stand having a rear tyre locked with a normal bicycle lock can be easily lifted to a waiting van, for instance. It may not necessarily be very useful to lock the front tyre to the stand with a separate lock as the front tyre can be easily disengaged from the bicycle and it can be left in the stand and the remaining parts of the bicycle can be taken along. The only slightly better alternative is to lock the frame or the back tyre of the bicycle to a solid construction with a separate detachable lock. It is difficult to transport the lock and it may be forgotten to be fastened inadvertently or in a hurry. It is also comparatively easy to open this kind of a separate lock, e.g. a spiral lock, with other keys and a safety pin, for example. DE 40 14 158 discloses a bicycle stand to which bicycles can be lifted to suspend. The stand comprises a securing part supported by which bicycles can be lifted to suspend from their frames. The securing part has a lock and the lock a catch by means of which the bicycle frame is locked to the securing part. The stand is heavy, complicated and therefore expensive and difficult to manufacture. Further, the stand is difficult to use as the bicycle has to be lifted upwards. And also, a separate key included in the lock of the stand has to be used for locking. FI 923,455 discloses a bicycle stand in which a bicycle is stored suspended on hook-like suspension parts from the handle-bar in the vertical position. The suspension parts can be moved from the removal position of the bicycle, in which the parts are outside the frame parts, to the locking position in which the parts are protected by the frame parts in a slot or a notch. The parts can be locked to each other by means of a padlock fitted to the tongues. The frame parts of the stand have to be secured either to the wall or to a separate stand, whereby the structure will be difficult, complicated and expensive. The bicycle needs to be locked to the stand with a separate padlock and the movable suspension parts are of a light structure which makes it rather easy to wrench them off, whereby the bicycle will get stolen. The object of this invention is to provide a bicycle stand that does not have the above-mentioned drawbacks. The bicycle stand according to the invention is characterized in that the bicycle stand comprises guide surfaces that are arranged obliquely with respect to the bicycle tyre, whereby the guide surfaces form a guide for guiding the catch, and that the bicycle stand comprises means for locking the catch into a locking position. The essential idea of the invention is that there is a swivelling axis in the stand around which the bicycle tyre is arranged to pivot when placing it in the bicycle stand, that the stand has means for moving the catch device when placing the bicycle in the stand in such a manner that when placing the bicycle in the stand, the catch locks the bicycle tyre to the stand. A further essential idea of the invention is that the catch will open only when the bicycle tyre is pivoted around the swivelling axis. The idea of a further embodiment is that there are elements in the stand for locking the catch into a locking position by means of a separate lock, for instance. An advantage of the invention is that when placing the rear tyre of the bicycle in the bicycle stand and by locking the rear tyre with an ordinary bicycle lock, the pivoting of the tyre around the swivelling axis is prevented, whereby the catch keeps the tyre locked to the stand. A further advantage is that by locking the catch with a separate locking element to the stand into the locking position, the bicycle cannot be disengaged from the stand even by cutting the spokes. The invention will be explained in more detail in the accompanying drawings, in which Figure 1 illustrates an axonometric view of a bicycle stand according to the invention with the catch in an open position, Figure 2 illustrates an axonometric view of the bicycle stand according to Figure 1 with the catch in a closed position, and Figure 3 illustrates a cross section of a detail of the bicycle stand according to Figure 1. Figure 1 illustrates a bicycle stand 1 according to the invention. The bicycle stand 1 includes a frame 2 to which a supporting fork 3 is secured. The supporting fork 3 comprises two supporting iron rods installed so that a bicycle tyre 9 can be placed between them, whereby the supporting fork 3 retains the bicycle in an upright position. Further, the bicycle stand has a scoop 4 secured to a shaft 5, whereby a pivoted element 4 is arranged to rotate around the central axis formed by the swivelling axis of the shaft 5. The pivoted element 4 comprises a metal rod arranged to support the bicycle tyre 9 when placing the bicycle in the bicycle stand 1. The shaft 5 is placed in the bicycle stand 1 transversely with respect to the bicycle tyre 9. The shaft 5 is arranged to a chamber 6 in such a manner that it can rotate with respect to the chamber 6. A catch 7 is further arranged to the shaft 5 so that when the shaft 5 pivots, it also pivots the catch 7. The catch 7 is further arranged to move in a slot 8 of the chamber 6. The slot 8 is arranged to the chamber 6 obliquely so that the end of the slot 8 on the side of the supporting fork 3 is closer to the pivoted element 4 than its other end. In that case, when placing the bicycle in the bicycle stand 1, the bicycle tyre 9 pivots the pivoted element around the shaft 5, whereby the catch 7 also pivots around the shaft 5. At the same time, the slot 8 guides the catch 7 towards the pivoted element 4, that is, the edges of the slot 8 form guide surfaces that guide the catch 7. When the tyre 9 is placed in the bicycle stand so that the pivoted element 4 is in its lowest position, the catch 7 settles on top of the tyre 9 and locks it to the bicycle stand 1 as shown in Figure 2. The pivoted element 4 comprises a first locking link 10a and the frame 2 a second locking link 10b, respectively, which are settled against one another when the pivoted element 4 is in its lowest position. A counter plate 11 is placed in the pivoted element 4 in connection with the shaft 5 on the opposite side of the supporting fork 3. When removing the tyre 9 from the bicycle stand 1, the tyre 9 presses the counter plate 11 so that the shaft 5 also pivots. Figure 2 shows the bicycle stand 1 according to Figure 1 with the catch 7 in a closed position. The numbers in Figure 2 correspond to those in Figure 1. When the pivoted element 4 is in its lowest position as in Figure 2, the catch 7 has to be so low down that the tyre 9 cannot be lifted upwards and pulled over the shaft 5 without pivoting the tyre 9 with respect to the shaft 5. In that case, if the tyre 9 is the rear tyre of the bicycle, it can be locked with an ordinary bicycle lock, whereby it cannot rotate around its central shaft, nor pivot with respect to the shaft 5. On the other hand, the catch 7 should be arranged so that when the tyre 9 is pivoted with respect to the shaft 5 in such a manner that the lowest part of the tyre in the bicycle stand 1 rises, the catch 7 also lifts up, and thus allows the tyre 9 to be pivoted. It is theoretically possible that a locked bicycle tyre can be pivoted by cutting spokes next to the bicycle lock first . A theft of this kind can be prevented in winter storage, for example, by locking the first locking link 10a and the second locking link 10b to each another with a separate padlock 12, whereby the pivoted element 4 cannot be pivoted with respect to the shaft 5 and therefore the catch 7 will maintain in its closed position. The shaft 5 is preferably higher up than the lowest point of the tyre 9 when the tyre 9 is placed in the bicycle stand 1. In that case, the shaft 5 forms a sill that in part supports the tyre 9 and makes the position of the bicycle in the bicycle stand more secure. On the other hand, when the shaft 5 is placed in this way, the elevation of the catch 7 can be defined more freely. Figure 3 shows how the catch 7 is secured to the shaft 5. The numbers in Figure 3 correspond to those in Figures 1 and 2. The catch 7 must be able to pivot in the direction of the shaft 5 when it moves guided by the slot 8 between open and closed positions. This is made possible by securing the catch 7 to the shaft 5 by means of a joint 13 in the transverse direction with respect to the shaft. The drawings and the specification related thereto are only meant to illustrate the idea of the invention. In its details, the invention may vary within the scope of the claims. Therefore, several bicycle stands can be fastened to one another side by side. This construction also makes it more difficult for vandals to remove the bicycle stand. On the other hand, the bicycle stand can be fastened permanently to some solid construction, such as concrete or asphalt, with bolts, whereby it cannot be pivoted to open the catch 7. If the pivoted element 4 is formed suitably to support the tyre 9, the supporting fork 3 is not necessary for the bicycle stand. On the other hand, if the stand has supporting structures for the tyre, such as the supporting fork 3, the pivoted element 4 can be e.g. a similar plate as the counter plate 11, whereby the tyre 9 rests on these plates when placing the bicycle in the stand and when removing it therefrom. The supporting structures for the tyre, such as the supporting fork 3 or the suitably formed iron rods of the pivoted element 4, prevent the tyre 9 from being disengaged from the bicycle stand from the side. A fixed stud can be used instead of the shaft 5, on top of which stud a bushing is arranged, and the pivoted element 4, the counter plate 11 and the catch 7 are fastened to the bushing, whereby the central axis of the stud forms a swivelling axis. The guide surfaces for guiding the catch 7 can also be formed by placing two rods obliquely with respect to the tyre 9 so that the rods guide the movement of the catch 7 between them. The locking links 10a and 10b can be positioned at any place in the bicycle stand; it is essential that by locking them, the catch 7 will be locked into a locking position, whereby the bicycle cannot be disengaged from the stand even by cutting the spokes. The bicycle stand can be fastened to a wall, for example, in such a manner that it can be lifted out of the way for the duration of ploughing or sanitation work. The bicycle stand can also be constructed so that the bicycles can be placed therein obliquely so that the space occupied by them will be smaller.
