1. Field of the Invention.
The invention relates to an articulation for the pushing handlebar of a small vehicle, more particularly of a pram, a lawn-mower and the like, whereas the articulation is provided with two projections used for connection with the frame of the small vehicle on one hand and with the pushing handlebar o on the other, whereas the articulation is showing a housing fitted with an adjusting device thanks to which the projections of the articulation may be locked into variable positions relative to each other.
1. Field of the Invention.
The invention relates to an articulation for the pushing handlebar of a small vehicle, more particularly of a pram, a lawn-mower and the like, whereas the articulation is provided with two projections used for connection with the frame of the small vehicle on one hand and with the pushing handlebar o on the other, whereas the articulation is showing a housing fitted with an adjusting device thanks to which the projections of the articulation may be locked into variable positions relative to each other.
2. Description of the Prior Art.
An articulation as mentioned above is well Icnown; it serves, especially when used on prams, to change the adjusting angle of the pushing handlebar relative to the frame so that such a pram may comfortably be pushed by persons of different stature.
Other prams are known, whose pushing handlebar is not adjustable. Theseprams however are provided with a Bowden cable running from a hand lever arranged on the pushing handlebar to a corresponding joint in the pram's frame and used to unlock from the pushing handle the joint of the pram in order to fold it. On prams having an articulation on the pushing handle, such a Bowden cable can naturally not be arranged, since the length of the Bowden cable would necessarily change when the pushing handlebar is pivoted, entailing thus the unlocking of the joint connected with the Bowden cable according to the direction into which the pushing handle is pivoted.
CA 02248074 l998-09-03 SUMMARY OF THE INVENTION
The object of the present invention is therefore to provide an articulation for the pushing handlebar of a small vehicle as mentioned above, whereas a s Bowden cable as described above may still be used without the Bowden cable bein necessarily actuated when the pushing handlebar is adjusted or pivoted .
The solution of the invention consists in an articulation in which the o Bowden cable is guided centrically in the articulation, its ends projecting out of the housing, one on each projection. Thanks to this centrical guiding of the Bowden cable in the articulation, that means a guiding of the Bowden cable in the area of the neutral axis of the articulation, the pushing handlebar may be pivoted ad lib without occasioning the shortening or lengthening of the Bowden cable arranged on the pushing handlebar. That means that the Bowden cable may be actuated in any position of the pushing handlebar.
The housing is consisting in two housing parts, whereas each projection arranged either on the pushing handlebar or on the frame of the small vehicle is connectable with one housing part. The design also provides each housing part in the area of the projection with an opening through which the Bowden cable may be passed. In order to securely guide the Bowden cable in the adjusting device, that means in the articulation, the adjusting device is equipped with a guide bush for the Bowden cable. Hereby, the guide bush is arranged parallel and centrically to the rotation axis of the articulation in the articulation.
According to a particular characteristic of the invention, the housing parts are each provided with an internal gear of differing diameter, whereas the adjusting device used for coupling the two housing parts shows a coupling member, whereas the coupling member is slidable parallel to the rotation axis of the articulation in such a way that, in a first position, the two housing parts may be positively interlocked and that, in a second position, the two housing parts may be twisted relative to each other That means that the pushing handlebar may be fixed in various positions relative to the frame of the small vehicle. The design moreover provides the coupling member with two gear rims of differing'diameter, whereas the diameter of each gear rim fits the corresponding diameter of the internal gear in the housing parts. Thus, one gear rim of the coupling member is continuously 10 positively engaged with one internal gear of one housing part, whereas the other gear rim may optionally be brought into or out of interaction with the internal gear of the other housing part.
According to a particular characteristic of the invention, the gear cutting of the coupling member's gear rims and correspondingly the internal gear of the housing parts are provided with teeth whose profile is running parallel to each other. Forces are resulting from the interlocking of the teeth with each other when their profile is tapered, whereas one force is directed vertically towards the tooth's profile and the other one towards the tip of the tooth. The force towards the tip of the tooth brings the corresponding housing part to extend its circumference, since the articulation according to the invention is made of plastics. That means that, when submitted to a certain strain, the housing part will get distorted. Ultimately thus, the internal gear of the housing part can no more receive properly the gear rim of the coupling member.
When the teeth are provided with parallel profiles, no force becomes effective onto the housing part, even under big strain. Thus, the housing part does not get distorted.
The adjusting device shows a bottom element arranged in one of the housing parts, whereas the bottom element possesses a snap-in case for its connection with the other housing part, whereas the coupling member may slidably be guided by the snap-in case. Moreover, the snap-in case not s only serves for guiding the spring provided between bottom element and coupling member, but also for guiding the coupling member itself. That means that the snap-in case arranged on the bottom element has several functions; it connects the two housing halves together and it serves for guiding not only a spring but also the coupling member. One housing part is 10 provided with a cover for fastening the bottom element in the housing. The cover is hereby advantageously arranged in the one housing part so as to be clampable and thus removable.
The other housing part advantageously shows a bottom rim, whereas the bottom rim is provided with at least one opening, and whereas this other housing part is provided with a push-button having at least one push-pin which, against the spring's force, disengages the coupling member from the internal gear of the other housing part through the opening in the bottom rim. This clearly shows that, when actuating the push-button, the two housing parts are pivotable relative to each other, since in this case one gear rim of the coupling member may be disengaged from the internal gear of the other housing part, whereas, due to the force exerted by the spring onto the coupling member, this coupling member is locked with the corresponding gear rim into the internal gear of the other housing part when the push-button is released.
According to a particular characteristic of the invention, the snap-in case receives the guide bush for the Bowden cable clamping it and protecting it from distortion, thus guaranteeing a durable good guiding of the Bowden cable in the neutral axis, that means, in the central rotation axis of the articulation .
CA 02248074 l998-09-03 Another object of the invention is a small vehicle, for example a pram or a lawn-mower, characterized by an articulation according to one or more of the previously discussed claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S) The articulation referred to as a whole with numeral 1 shows a housing 2, consisting in the two housing parts 11 and 21, whereas the housing part 11 has been provided with a projection 10 and the housing part 21 with projection 20. Moreover, the housing 2 is provided with the push-button referred to with numeral 30. The Bowden cable referred to with numeral 40 iS passing through the articulation. For a better understanding of the functioning of the different component parts of the articulation and more particularly of the different component parts of the adjusting device, please consult Figure 5. In Figure 5 first may be seen the two housing parts 11 and 21 which are receiving the adjusting device. The adjusting device is composed of the following components: bottom element 50, compression spring 60, coupling member 70 and push-button 80. For the assembly of the different components 50 to 80 of the adjusting device, the proceeding is the following: first of all, the one housing part 21 receives the bottom element 50 with the snap-in case b1. The snap-in case 51 receives and guides the spring 60. The coupling member 70 is resting on the spring 60 10 together with the two gear rims 71 and 72, having each another diameter.
The snap-in case 51 also passes through this coupling member, whereas the snap-in case is ultimately extending into the other housing part 11, and is positively interlocked with it in the area of the bottom rim 12. The snap-in noses 52 of the snap-in case 51 are hereby back-clamping a corresponding collar 17 in the bottom rim. A cover 90 is provided to fasten the bottom element 50, said cover having snap-in members 91 projecting into corresponding recesses 22 of a housing part 21. The other housing part 11 is receiving the push-button 80; the push-button 80 is hereby provided with snap-in members 81 for its fastening in the housing part 11, said snap-in members corresponding to the snap-in members 91 of cover 90 and snapping into corresponding recesses 13. Moreover, the push-button 80 is provided with push-pins 82, which are acting onto the coupling member through corresponding openings 15 in the bottom rim 12 of the housing. For the guiding of the Bowden cable 40 the guide bush 100 iS moreover provided, whereas said guide bush may be received by the snap-in case 51 so as to be clamped and guarded from distortion. The guide bush 100 has a through boring 101 serving for the guiding of Bowden cable 40.
The articulation is now functioning as follows. The push-button 80 is pushed, throwing the conical gear rim 72 out of the internal gear 16 CA 02248074 l998 - 09 - 03 arranged in the bottom rim of housing part 11 against the compression spring's 60 force in direction of the arrow 120, so that the projections 10, 20 are twistable relative to each other. When the push-button is released, the coupling member 70 is moved against the arrow's 120 direction with 5 its conical gear rim into the internal gear 16 of bottom rim 12 of housing 11, whereas the two housing parts 11 and 21 are interlocked in this position since the coupling member 70 is linked on one side by gear rim 71 with internal gear 23 and on the other by the conical gear rim 72 with the internal gear 16.
The gear rims 71, 72 as well as the teeth 18, 25 of the corresponding internal gear are both provided with parallel running profiles in order to avoid the upcoming of a force exerted towards the housing part when strained .
An articulation as mentioned above is well Icnown; it serves, especially when used on prams, to change the adjusting angle of the pushing handlebar relative to the frame so that such a pram may comfortably be pushed by persons of different stature.
Other prams are known, whose pushing handlebar is not adjustable. Theseprams however are provided with a Bowden cable running from a hand lever arranged on the pushing handlebar to a corresponding joint in the pram's frame and used to unlock from the pushing handle the joint of the pram in order to fold it. On prams having an articulation on the pushing handle, such a Bowden cable can naturally not be arranged, since the length of the Bowden cable would necessarily change when the pushing handlebar is pivoted, entailing thus the unlocking of the joint connected with the Bowden cable according to the direction into which the pushing handle is pivoted.
