Description

DEVICE FOR RESILIENT SUPPORT OF A LUGGAGE CARRIER OR A CHILD'S SEAT ON A BICYCLE
A number of different devices for fastening a child's seat to a bicycle are known. According to a known embodiment, a retaining device consisting of a generally rectangular plate is placed on the bicycle frame, underneath the seat, at each end of which device is constructed of two tubular bends. This plate is then screwed to the bicycle frame. Correspondingly, two arms project from the child's seat, each end of the arms being bent downwards at approximately right angles. The ends of each of these two arms are then placed in the tubular bends so as to hold the child's seat in place.
Ordinary, known luggage carriers for bicycles are normally fastened to the seat bar of the bicycle and the hub bolt of the rear wheel. This type of luggage carrier is not provided with any form of dampening.
When cycling in rugged terrain and across for instance tramway rails, kerbstones and other uneven ground and carrying luggage or a child in a child's seat, the child or the load on the luggage carrier will be displaced upwards when the rear wheel hits a bump in the road. This may cause the load that is held on the luggage carrier, for instance in the form of panniers, to loosen, or to fall off if the bump is large enough, and may cause a loss of control over the bicycle due to the rear wheel wholly or partly losing contact with the ground, because the load pulls the bicycle frame with it in the upward direction. If a conventional child's seat is fitted on the luggage carrier, the child will be subjected to all the bumps hit by the rear wheel. This problem has been made more relevant as a result of the change in people's cycling habits, due among other things to the development of so-called off-road bicycles, which allow cycling to take place on gravel roads and paths with more unevenness than what has normally been the case. These jolts are particularly uncomfortable for a child who sits in a child's bicycle seat and is unprepared for the bumps, passively absorbing the jolts.
Thus, an object of the present invention is to provide a device for securing a luggage carrier or a child's seat to a bicycle, where the device to an essential degree prevents the jolts to which the bicycle is subjected being transmitted to the child in the seat or the luggage on the carrier.
Another object is to provide a device of the type described at the beginning, which device ensures that the centre of gravity of the loaded bicycle is positioned as low as possible.
These objects are achieved by means of a device for resilient support of a luggage carrier or a child's seat on a bicycle, characterised by the device comprising a retaining device attached to the frame of the bicycle, one or two arm elements rotatably attached to the retaining device near their ends, and one or two dampening devices, one end of which is attached to the arm element and the other end of which is attached to the retaining device or a part of the bicycle, which dampening device comprises springs or elastomers with adjustable stiffness.
Preferably, the arm element is at one end attached to the dampening device at an attachment point, and at a distance from its extreme end attached to the retaining device at an attachment point, the dampening device at one end being rotatably attached to the arm element at an attachment point and at the other end being rotatably attached to the retaining device at an attachment point.
According to a preferred embodiment of the invention, the arm element is provided with a sleeve, and a stay extends slideably through the sleeve from the hub of the rear wheel, which stay may be connected to the hub of the rear wheel by means of an intermediate member and a rotatable joint.
According to another preferred embodiment of the device according to the invention, the arm element is rotatably connected to the retaining device at its extreme end, and at a distance from its extreme end rotatably connected to the dampening device at an attachment point, which dampening device at its other end is connected to the hub of the rear wheel, possibly by means of an intermediate member and a rotatable joint. According to yet another preferred embodiment of the device according to the invention, the arm element is, near its extreme end, rotatably connected to the retaining device at an attachment point, and this extreme end abuts a dampening body provided between the retaining device and the extreme end of the arm element, which retaining device is connected to two separate parts of the bicycle frame.
The invention also relates to a device for resilient support of a luggage carrier or a child's seat on a bicycle, characterised by the inclusion of a pair of arm elements provided on either side of the bicycle, a support for securing the luggage carrier or the child's seat, and a dampening device provided between the support and the arm elements, a bracket connecting the two arm elements, which arm elements are connected to the hub of the rear wheel at one end and to a part of the bicycle frame at the other end, which dampening device comprises two pairs of arms rotatably connected to the support at one end and at the other end rotatably connected to the arm elements, and possibly the bracket, where an axle has been provided between a pair of the attachment points for the upper or lower pair of arms, and that a spring has been provided between said axle and the bracket, the stiffness of which spring is adjustable by means of a set screw.

Figure 11 is a perspective view showing further characteristics of the device shown in Figures 8-10.
Figure 1 shows a first embodiment of a device for support of a child's seat or a luggage carrier on a bicycle. The device consists of a bent arm element 1, a retaining device 2 attached to the frame 4 of the bicycle 3, and a dampening device 5. The arm element 1 may be designed as two independent arm elements 1 arranged on either side of the bicycle 3, or the arm element 1 may take the form of an approximately U-shaped body spanning the bicycle 3. The arm element 1 is rotatably attached to the retaining device 2 at a point 6 near one end of the arm element. This attachment point 6 may be in the form of a through bolt securing the arm element 1 on either side of the bicycle 3 to the retaining device 2. At the extreme end of the arm element 1 and at a relatively short distance from the attachment point 6, the arm element 1 is rotatably attached to a dampening device 5 at a point 9. The dampemng device 5 is in turn attached to a protruding arm 6 on the upper part of the retaining device 2, at a point 8.
When the bicycle hits a bump in the road, the arm element 1, which is rotatably supported at the point 6, will move downwards in relation to the bicycle. This movement is transmitted due to the leverage of the dampemng device 5, thus compressing this. The dampemng device, which in this embodiment consists of a telescopic absorber based on either steel springs or an elastomer, is supported at attachment points 8 and 9. The dampening may be adjusted according to the weight of the child or the load, either by altering the damper's attachment point 9 for the arm element 1 or its attachment point for the frame 4, i.e. adjust the ratio between force and arm, or by biasing the spring.
Figure 2 shows a version of the embodiment shown in Figure 1. The difference between the embodiment shown in Figure 1 and the version shown in Figure 2 lies in the location and the design of the dampening device 5. The arm element 1 is attached to the retaining device 2 at an attachment point 6 and to the dampemng device 5 at a point 9, as in the previous embodiment. In this embodiment, the dampemng device 5 is attached to the retaining device 2 at a point 8, which in this embodiment is placed below the attachment point 6 that connects the arm element 1 and the retaining device 2.
In this embodiment, the arm element 1 will be dampened for instance by means of one or more elastic bands. The movement of the arm element 1 causes the elastic band(s) to stretch between the arm element 1 and the attachment to the frame 4. The dampening may be adjusted according to the weight of the child or the load, by using elastic bands with differing hardness.
Figure 3 shows a second embodiment of the device according to the invention. In this embodiment, the arm element 1 is at one end rotatably attached to a retaining device 2 at a point 6. The retaining device 2 is attached to the frame 4 of the bicycle 3 as before. The arm element 1 is rotatably attached to a dampening device 5 at a point 10 between each end of the arm element 1. The dampening device 5 is in turn rotatably attached to the hub bolt 12, possibly via an intermediate member 13. If an intermediate member 13 is used, the dampening device 5 may be rotatably attached to the intermediate member 13 at a point 11, and the intermediate member 13 is in turn non-rotatably attached to the hub bolt 12 of the rear wheel.
Figure 4 shows a perspective view of the embodiment show in Figure 3. Here, the arm element 1 is shown as a generally U-shaped bow, which at both ends is attached to the retaining device 2 by means of a rotatable fastening 4. Each dampening device 5 is attached to the arm element 1 by means of a rotatable fastening 10. In order to achieve additional stability, a stay 14 may be provided between the two attachment points 10.
In this embodiment, the movement is dampened by two dampening devices 5 provided on either side of the bicycle 3. The dampening may be adjusted by biasing the spring or the elastomer, or by replacing the spring or elastomer with a spring or elastomer with a different stiffness. It is also possible to alter the attachment points for the telescope absorbers for the arm element 1, and thereby adjust the dampening by altering the ratio between force and arm.
Figure 5 shows an embodiment of the device according to the invention. This embodiment is a version of the embodiments shown in Figures 1 and 2. What distinguishes this third embodiment from the embodiments shown in Figures 1 and 2, is the provision of an additional stay 15 on one or both sides of the bicycle. The additional stay 15 is at its lower end rotatably attached to a point 16. In the embodiment shown, the stay 15 is rotatably connected to an intermediate member 17 at the point 16, which intermediate member is in turn attached to the hub bolt 12. However, the lower end of the stay 15 may also be rotatably attached directly to the hub bolt without an intermediate member 17. At the upper end, the stay is slideably connected to the arm element 1 , for instance by means of a sleeve 18 attached to the arm element 1. This provides the device with greater torsional rigidity.
Figure 6 shows an alternative embodiment of a fastening device 2 for securing the device according to the invention to the frame 4 of the bicycle 3. As in the embodiments described above, a retaining device 2 is attached to the bar 4 of the bicycle 3. The arm element 1 is rotatably connected to the retaining device 2 at a attachment point 6. The end of the arm element 1 that is closest to the bicycle bar 4 is bent, so as to let this end of the arm element 1 rest against a dampening device 22 provided between the retaining device 2 and the arm element 1. In order to secure the device further to the bicycle, and to prevent the device from rotating about the bar 4, the retaining device 2 is provided with a second retaining device 19, which is attached to the cross-bar 20. The embodiment of the bicycle 3 shown in solid lines is a man's bicycle, where the crossbar 20 extends approximately horizontally from the seat bar 4 to the column for the handle bars (not shown). The embodiment shown in broken lines is a ladies' bicycle, where the cross-bar 21 is attached further down on the seat bar 4. In order to be able to adapt the second retaining device 19 to bicycles with the cross-bars 20 and 21 at different positions, it is rotatably connected to the retaining device 2 at a point 23.
The dampening device 22 may for instance consist of a block of elastomer that absorbs and dampens the movements of the arm element 1. The degree of dampening may be adjusted by using blocks of elastomer exhibiting different hardness.
Figure 7 shows a version of the embodiment shown in Figure 2, where the retaining device 2, which is attached to the seat bar 4 in the same manner as before, is also attached to the bar 24 extending between the seat bar 4 and the rear wheel hub of the bicycle.
Figures 8-11 show yet another embodiment of the device according to the invention. In this embodiment, the arm element 25 is immovable, unlike the arm element 1 shown in Figures 1-7. The arm element 25 is attached to the rear wheel hub 12 and a retaining device 2 respectively, the retaining device in turn being attached to the bicycle frame 4. This embodiment comprises separate arm elements 25 on either side of the bicycle 3. In addition to the arm elements 25, the device according to this embodiment consists of a support 26 connected to the arm elements 25 by means of a dampemng body shaped as a parallelogram. The dampening body, shown in greater detail in Figures 9-11, consists of an upper pair of arms 27 and a lower pair of arms 28, extending between the support 26 and the arm elements 25. The upper arms 27 are rotatably attached to the support 26 at an attachment point 29, and to the arm elements 25 at an attachment point 30. The lower arms 28 are rotatably attached to the support 26 at an attachment point 31, and to the arm elements at an attachment point 32. Further, a spring 33 is placed approximately diagonally between the attachment point 29 and the attachment point 32, or the attachment points 31 and 30, one end of which spring is attached to an axle provided between the attachment points 29 or 31.
The upper arms 27 may be interconnected by means of a plate-shaped piece 34, and the arms 27 and the plate-shaped body 34 may be constructed as one unit (Fig. 11). The dampemng body further comprises an adjustment mechanism for adjusting the spring constant of the spring 33. The adjustment mechanism consists of a bracket 35 secured to both arm elements 25, preferably at the same attachment points at which the upper and lower arms 27, 28 are attached to the arm elements 25. A set screw 36, the outer end of which is threaded, has been set in this bracket 35. Further, elongated slots 37 have been provided at either end of the bracket 35, between which slots 37 an axle 38 moveable in the slots 37 has been placed. The spring 33 is attached to the axle 38 at one end, and the axle 38 or the spring 33 is provided with a threaded hole at this end. The threaded end of the set screw 36 engages the threaded hole, either at the end of the spring or the axle 38, so that rotation of the screw 36 will cause the axle to move in the slot 37, causing a change in the ratio between force and arm. This results in a change in the spring constant.
