Abstract
A spring-mounted saddle support for bicycles has an upper part (10) and a lower part (20) axially movable towards each other on springs (30), but so as not to turn. The upper part can be linked to the saddle and the lower part can be inserted into the saddle tube of the bicycle frame.
Description
Spring-cushioned bicycle saddle support devices are already known. An exceptionally well functioning bicycle saddle support device with excellent side guiding and significant spring travel is described in the German Utility Model 89 02 327. This known spring-cushioned saddle support device is, just like other spring-cushioned saddle support devices according to the state-of-the-art, conceived so, that it necessitates a bicycle 1~ frame of a special construction to enable its use, whereas a conventional bicycle frame construction cannot be used with a spring-cushioned saddle support.
However, a bicycle equipped with a special frame and a well sprung saddle support device, like the one known from the Utility Model 89 02 327, is relatively axpensive. For this reason and to enable the retrofitting of existing conventional bicycles with a spring-cushioned saddle support, it is desirable to produce a spring-cushioned saddle support, which can be mounted in the saddle support tube of a conventional bicycle frame instead of the usual rigid saddle supports.
This ob~ective is achieved according to the invention by a spring-cushioned saddle support characterised in the claims.
As in the case of the spring-cushioned saddle support according to the invention the spring is situated between the top end of the saddle support tube of the bicycle frame and the bicycle saddle and a spring travel of at least 4 cm to 6 cm is required, a corresponding overall height of the spring-cushioned saddle support above the top end of the saddle support tube of the bicycle frame will inevitably result, which however usually does not cause any problem, as the usual height of the saddle above the frame, in any case for most adult 3s bicycle riders and for most common bicycle frames, in particular for the so called mountain bikes, allows without any difficulty the required overall height of the spring-cushioned saddle support.

lne inv~ntion is explained below in detail based on some embodiments by referring to the attached drawings.
Figs.l to 6 of the drawings show six different embodiments of the invention, each sectioned along the axis.
In all six versions of the embodiment the spring-cushioned saddle support consist of a top part 10 with a top saddle carrier spigot 11 and a top spring rest 12, a bottom part 20 with a bottom tube support 21 which is to be inserted into the saddle support tube and a bottom spring rest 22, a helical compression spring 30 provided between the top spring rest 12 and the bottom spring rest 22, a guide rod 40 which is fastened in the top part 10 and extends centrally through the entire saddle support and carries on its bottom end, which protrudes past the tube extension 21, a stop 42 which is provided with a buffer 41, and means to prevent the rotation hetween the top part 10 and the bottom part 20, which means are di~ferent in each of the four versions of the embodiments.
In the case of the embodiments according to Figs.l and 2 on the top part 10 and the bottom part 20 telescopic tube members 13 and 23 are provided, which originate rou~hly from the respective spring rests 12 and 22 and which telescope into each other, while in each case the inner telescopic tube member 23 is arranged on the bottom part 20 and the outer telescopic member 13 on the top part 10. The inner telescopic tube member 23 has splines on its outside, i.e. on its outer circumference it has a rim of key-].ike teeth which are parallel to the axis, and on the inner circumference of the outer te].escopic tube member 13 corresponding key grooves are formed, so that both telescopic tube members 13 and 23 are guided relative to each other in such a manner that their relative rotation is prevented but they can be axially displaced relative to each other. At the same time the profiled section of one of the two telescopic members, preferably of the outer one, may be made of plastic material, so that during the interaction of the two telescopic tube members a metal/plastics contact will result, ' .
~ v v i - u i~ v - ' -- -having a lower friction on the one hand and working ~uietly on the other.
In the case of the embodiment according to Fig.1 the two 5 telescopic tube members 13 and 23 enclose the spring 30, whereas in the case of the embodiment according to Fig.2 the spring is provided on the outside and it surrounds the telescopic tube members. The version according to Fig.1 is more advantageous inasmuch that no dirt will reach the spring and an inadvertent access to the spring is impossible; the version according to Fig.2 meets the requirement to make the spring visible.
The possible spring travel of the spring-cushioned saddle support is limited in the direction of compression of the spring by the mutual telescoping of the top part 10 and the bottom part 20 until the corresponding stop faces impact each other, and in the direction of the expansion of the spring 30 by the buffered stop 42 at the end of the guide rod 40 which stop interacts with the bottom face of the tube extension 21.
During the springing process, the guide rod 40, which is guided in the bottom part in the upper and lower guide bushes 43 and runs smoothly and with low wear, serves the purpose of an accurate guiding of the top part 10 relative to the bottom part 20 without excessive stress on the interacting splines of the two telescopic tube members 13 and 23.
In the case of the embodiment according to Fig.1 the outer telescopic tube member ~3 has an a~ial slot at one place on its circumference and can be tightened elastically in the circumferential direction by means of a tensioning strap 50 inserted into a circumferential groove 14 and a tension lock 51, thus making feasible the setting and adiusting of the engagement of the outer spline of the inner telescopic tube member 23 in the spline grooves of the outer telescopic tube member 13.
.
.
~ ii In the case of the embodiment according to Fig.l the bottom part 20 has inside of the spring 30 a protruding projection 24, in which the upper guide bush 43 is provided. In the case of the embodiment according to Fig.2 the upper guide bush is S inserted in the top region of the inner telescopic tube member 23.
In the embodiments according to Figs.3 and 4 the means preventing a relative rotation are provided off-centre. In the embodiment according to Fig.3 on the top part 10 and the bottom part 20 guide elements 16 and 26, respectively, are provided, which can be, as illustrated, positively interacting telescoping members 16, 26, or the two guide elements may be constructed with a guide profile in which a body having a sliding pad-like construction is being guided.
In the case of the embodiment according to ~ig.4 the relative rotation is prevented by a tensioning strap 60, consisting of two members 61 and 62, which are connected with each other by a hinge 63 which is hinged on the top part 10 and the bottom part 20 by means of a hinge 64 each, with the axes of the hinges situated perpendicularly to the longitudina3 axis of the guide rod 40. At the same time both link strap members 61 and 62 may have a straight or curved shape.
In the case of the embodiment according to Fig.5 the relative rotation is prevented in that the guide rod 40 has an axial keyway 45, with which one or several keys 25 engage (two in the embodiment illustrated here). The keys are inserted into the tube extension 21 of the bottom part 20. ~o ensure a good guiding and low wear even when shear forces act on the saddle, when, for example, the load is applied by the bicycle rider to one side of the saddle only, which can be the case when riding through field tracks or the like, an adequately long guiding length is necessary, which is the reason why two keys are being used (as illustrated~. Naturally, as an alternative, one correspondingly long key may be used.
~ .
~ U U ~ 'J -- -The version according to Fig.6 can be compared in its effect with the embodiments according to Fig.l or Fig.3, but it is different in that it is particularly easy to manufacture. As can be seen from the adjacent perspective isometric illustration in Fig.7, the top part 10 has two (or more) fingers 17, which engage the corresponding slots 27 of the bottom part 20 and thus prevent their relative rotation. When compared with the splines of the version according to ~ig.l this version is considerably less expensive to produce; in comparison with the version according to Fig.3 the a~vantage is in better accuracy of guiding and greater stability. The edge surfaces 17a on both sides of the fingers 17 and the edge surfaces 27a on both sides of the slots 27 can be, as illustrated, in the radial direction; however, they can also be parallel, which may be easier as far as manufacturing technology is concerned. Apart from the manufacturing technologies, which may be milling, grinding or the like, the two constructions are of equal value.
Incidentally, the version according to Fig.6 in its internal construction corresponds to that of Fig.1, which is the reason why further elements, already explained in relation to Fig.1, are not described again.
Fig.8 shows a sideview of a modification of the embodiment according to Fig.6, wherein, however, the saddle s~pport of Fig.8 is rotated at 90 relative to the illustration in Fig.6, so that one ~inger 17 and one slot 27 each can be seen. This development differs from the version according to Fig.6 in that the top part 20 has a top tap~red section 28 on its outer circumference, while the bottom region has an outer thread 29 onto which a clamping nut 70 is screwed, the inner surface of which is in contact with the tapered region 28, is also tapered. By tightening the clamping nut 70 to varying degrees, both flanks of the bottom part, situated on both sides of the slot 27, can be clamped slightly against each othsr and thus the sliding fit between the fingers 17 of the top part and the slots 27 of the bottom part can be adjusted.
.
:
- - -- - - -As will be understood without any difficulty, there is a further (not illustrated) version according to the principle of Fig.8, analogous with the modification of the embodiment of Fig.1 to that of Fig.2. Similarly to Fig.2, where the splined members 13 and 23 provided outside of the spring 30 in Fig.l can be provided inside of the spring 30, in a modification of the embodiment according to Fig.8 and Fig.6, respectively, the fingers 17 of the top part and the corresponding flanks of the bottom part which form the slots 27 to guide the fingers can be provided inside of the spring 30, which in that case will have a correspondingly greater diameter.

However, a bicycle equipped with a special frame and a well sprung saddle support device, like the one known from the Utility Model 89 02 327, is relatively axpensive. For this reason and to enable the retrofitting of existing conventional bicycles with a spring-cushioned saddle support, it is desirable to produce a spring-cushioned saddle support, which can be mounted in the saddle support tube of a conventional bicycle frame instead of the usual rigid saddle supports.
This ob~ective is achieved according to the invention by a spring-cushioned saddle support characterised in the claims.
As in the case of the spring-cushioned saddle support according to the invention the spring is situated between the top end of the saddle support tube of the bicycle frame and the bicycle saddle and a spring travel of at least 4 cm to 6 cm is required, a corresponding overall height of the spring-cushioned saddle support above the top end of the saddle support tube of the bicycle frame will inevitably result, which however usually does not cause any problem, as the usual height of the saddle above the frame, in any case for most adult 3s bicycle riders and for most common bicycle frames, in particular for the so called mountain bikes, allows without any difficulty the required overall height of the spring-cushioned saddle support.

lne inv~ntion is explained below in detail based on some embodiments by referring to the attached drawings.
Figs.l to 6 of the drawings show six different embodiments of the invention, each sectioned along the axis.
In all six versions of the embodiment the spring-cushioned saddle support consist of a top part 10 with a top saddle carrier spigot 11 and a top spring rest 12, a bottom part 20 with a bottom tube support 21 which is to be inserted into the saddle support tube and a bottom spring rest 22, a helical compression spring 30 provided between the top spring rest 12 and the bottom spring rest 22, a guide rod 40 which is fastened in the top part 10 and extends centrally through the entire saddle support and carries on its bottom end, which protrudes past the tube extension 21, a stop 42 which is provided with a buffer 41, and means to prevent the rotation hetween the top part 10 and the bottom part 20, which means are di~ferent in each of the four versions of the embodiments.
In the case of the embodiments according to Figs.l and 2 on the top part 10 and the bottom part 20 telescopic tube members 13 and 23 are provided, which originate rou~hly from the respective spring rests 12 and 22 and which telescope into each other, while in each case the inner telescopic tube member 23 is arranged on the bottom part 20 and the outer telescopic member 13 on the top part 10. The inner telescopic tube member 23 has splines on its outside, i.e. on its outer circumference it has a rim of key-].ike teeth which are parallel to the axis, and on the inner circumference of the outer te].escopic tube member 13 corresponding key grooves are formed, so that both telescopic tube members 13 and 23 are guided relative to each other in such a manner that their relative rotation is prevented but they can be axially displaced relative to each other. At the same time the profiled section of one of the two telescopic members, preferably of the outer one, may be made of plastic material, so that during the interaction of the two telescopic tube members a metal/plastics contact will result, ' .
~ v v i - u i~ v - ' -- -having a lower friction on the one hand and working ~uietly on the other.
In the case of the embodiment according to Fig.1 the two 5 telescopic tube members 13 and 23 enclose the spring 30, whereas in the case of the embodiment according to Fig.2 the spring is provided on the outside and it surrounds the telescopic tube members. The version according to Fig.1 is more advantageous inasmuch that no dirt will reach the spring and an inadvertent access to the spring is impossible; the version according to Fig.2 meets the requirement to make the spring visible.
The possible spring travel of the spring-cushioned saddle support is limited in the direction of compression of the spring by the mutual telescoping of the top part 10 and the bottom part 20 until the corresponding stop faces impact each other, and in the direction of the expansion of the spring 30 by the buffered stop 42 at the end of the guide rod 40 which stop interacts with the bottom face of the tube extension 21.
During the springing process, the guide rod 40, which is guided in the bottom part in the upper and lower guide bushes 43 and runs smoothly and with low wear, serves the purpose of an accurate guiding of the top part 10 relative to the bottom part 20 without excessive stress on the interacting splines of the two telescopic tube members 13 and 23.
In the case of the embodiment according to Fig.1 the outer telescopic tube member ~3 has an a~ial slot at one place on its circumference and can be tightened elastically in the circumferential direction by means of a tensioning strap 50 inserted into a circumferential groove 14 and a tension lock 51, thus making feasible the setting and adiusting of the engagement of the outer spline of the inner telescopic tube member 23 in the spline grooves of the outer telescopic tube member 13.
.
.
~ ii In the case of the embodiment according to Fig.l the bottom part 20 has inside of the spring 30 a protruding projection 24, in which the upper guide bush 43 is provided. In the case of the embodiment according to Fig.2 the upper guide bush is S inserted in the top region of the inner telescopic tube member 23.
In the embodiments according to Figs.3 and 4 the means preventing a relative rotation are provided off-centre. In the embodiment according to Fig.3 on the top part 10 and the bottom part 20 guide elements 16 and 26, respectively, are provided, which can be, as illustrated, positively interacting telescoping members 16, 26, or the two guide elements may be constructed with a guide profile in which a body having a sliding pad-like construction is being guided.
In the case of the embodiment according to ~ig.4 the relative rotation is prevented by a tensioning strap 60, consisting of two members 61 and 62, which are connected with each other by a hinge 63 which is hinged on the top part 10 and the bottom part 20 by means of a hinge 64 each, with the axes of the hinges situated perpendicularly to the longitudina3 axis of the guide rod 40. At the same time both link strap members 61 and 62 may have a straight or curved shape.
In the case of the embodiment according to Fig.5 the relative rotation is prevented in that the guide rod 40 has an axial keyway 45, with which one or several keys 25 engage (two in the embodiment illustrated here). The keys are inserted into the tube extension 21 of the bottom part 20. ~o ensure a good guiding and low wear even when shear forces act on the saddle, when, for example, the load is applied by the bicycle rider to one side of the saddle only, which can be the case when riding through field tracks or the like, an adequately long guiding length is necessary, which is the reason why two keys are being used (as illustrated~. Naturally, as an alternative, one correspondingly long key may be used.

~ U U ~ 'J -- -The version according to Fig.6 can be compared in its effect with the embodiments according to Fig.l or Fig.3, but it is different in that it is particularly easy to manufacture. As can be seen from the adjacent perspective isometric illustration in Fig.7, the top part 10 has two (or more) fingers 17, which engage the corresponding slots 27 of the bottom part 20 and thus prevent their relative rotation. When compared with the splines of the version according to ~ig.l this version is considerably less expensive to produce; in comparison with the version according to Fig.3 the a~vantage is in better accuracy of guiding and greater stability. The edge surfaces 17a on both sides of the fingers 17 and the edge surfaces 27a on both sides of the slots 27 can be, as illustrated, in the radial direction; however, they can also be parallel, which may be easier as far as manufacturing technology is concerned. Apart from the manufacturing technologies, which may be milling, grinding or the like, the two constructions are of equal value.
Incidentally, the version according to Fig.6 in its internal construction corresponds to that of Fig.1, which is the reason why further elements, already explained in relation to Fig.1, are not described again.
Fig.8 shows a sideview of a modification of the embodiment according to Fig.6, wherein, however, the saddle s~pport of Fig.8 is rotated at 90 relative to the illustration in Fig.6, so that one ~inger 17 and one slot 27 each can be seen. This development differs from the version according to Fig.6 in that the top part 20 has a top tap~red section 28 on its outer circumference, while the bottom region has an outer thread 29 onto which a clamping nut 70 is screwed, the inner surface of which is in contact with the tapered region 28, is also tapered. By tightening the clamping nut 70 to varying degrees, both flanks of the bottom part, situated on both sides of the slot 27, can be clamped slightly against each othsr and thus the sliding fit between the fingers 17 of the top part and the slots 27 of the bottom part can be adjusted.
