Abstract

Bicycle handlebars with any desired number of, but at least three, basic postures and a multiplicity of grip positions. As is well known the demands made on the handlebars of a bicycle are the same despite use by different interest groups. No matter whether the cyclists go in for racing, touring or cycling for leisure all have the same problem of seized-up back muscles, painful backside and cramped-up hands. It is known that hitherto only racing handlebars offered the best cycling comfort on longer tours, cycling trips and above all when racing. This handlebars shape allows the essentially bent-over and stooped posture, it being possible for the grip positions to be changed. The proposed bicycle handlebars solve this problem in that the two holding grips have a closed, bent shape which lies in an approximately vertical plane.

Description

The invention relates to a bicycle handlebar with any, little at least three basic positions and a variety of grip positions.

Such a handlebar is of great practical and above all health interest and value. These are the requirements of a bike of different interests. So it can be as pure sports equipment in the race, as a touring and hiking bike or be used as a pure form of transportation.

There are three essential bicycle handlebars for these different purposes become known, in which the following basic attitudes are adopted can be:

• 1) The upright posture, in which the spine is almost vertical to the road and with the buttocks being the brunt of the waiter body carries. So-called touring handlebars are used for this.
• 2) The bent posture, in which the spine is about 45 ° behind lies in front of the road, with the arms part of the upper record body weight. For this, so-called trainings handlebar used.
• 3) The stooped posture, in which the spine is arched is tilted very flat forward, with arms even stronger be charged. So-called racing handlebars or stirrups are used for this used.

In the latter, different attitudes are adopted, e.g. when cycling, where in the so-called "rocking step", in the pedals standing, tackling larger inclines or a sprint. Here the handlebar position on the racing handlebar or bracket depends on the requirements stanchions changed. But there is always a more or less hunched over Posture that hinders free breathing. Besides, the cannot  full strength of the arms can be brought into the pedal work.

It is known that so far the racing handlebar or bracket on long tours, hiking trips and especially in the race offer the best driving comfort. It essentially enables the stooped and stooped posture, whereby the grip positions can be changed. (Tour - All about bike No. 2/1983 / page 31).

But so far it has not been possible to use all of the stances and grips mentioned combine positions in one handlebar.

An adjustable bicycle handlebar is under file number P 29 30 206 became known who tries to solve the same problem by by the adjustable handles are arranged adjustable. These Execution has the disadvantage that it is almost impossible to handlebars to adjust while driving because tools are required. In addition, constant change is necessary for known reasons agile. In addition, the handlebar width is adjusted changed. Guide the protruding screws and sharp edges to injuries. A handle part that is not absolutely stationary can when the arms are very hard, they sag and close too cause painful injuries.

A similar implementation as described above will be made in time "Cycling" issue 6/1982 page 17. Here are to name the same disadvantages.

Another version of a bicycle handlebar that described To solve the problem is described under file number P 31 39 861 ben. The important racing handlebar mentioned is missing from this version position with the stooped posture and other grip positions.

Common to all handlebars is the risk of injury from the handlebar ends (see report in "Cycling" No. 2/1985 page 18). Only the handlebar according to file number P 31 39 861 does not have this part after, since it consists of a closed tube train.

The invention is based on the object of a bicycle handlebar to create, which does not have these disadvantages mentioned and actually has the three basic attitudes mentioned, one Offers a variety of grip positions and less injuries leads to danger.

In addition, an upright, at Achieved favorable posture, with a much greater force can be put on the pedals.

This task is performed in a generic execution by characterizing features of claim 1 solved.

Appropriate equipment is the subject of the subclaims.

The invention is illustrated in the drawing, for example and described in detail below with reference to the drawing.

Fig. 1 shows a bicycle handlebar according to the invention in a perspective view from the front / above mounted on a handlebar stem.

Fig. 2 shows a bicycle handlebar according to the invention in a perspective view from the front / side of a Len kervorbau mounted.

Fig. 3 shows a top view of the handlebar

Fig. 4 shows a side view of the handlebar

Fig. 5 shows the three basic postures on the bicycle handlebar according to the invention

Fig. 1 shows an exemplary embodiment of the bicycle handlebar 1 in a perspective view mounted on a handle stem. 2 According to the invention, the two handles 3 form a closed, curved shape which lie in the vertical plane Z.

The end 4 of the closed curved handle 3 is positively and non-positively connected to the beginning 5 of the handle. In this example, this connection is an unsolvable one, such as soldering, welding, gluing or the like. In this embodiment, a Lenkervor construction 2 is selected, which allows assembly of the closed handles 3 .

In FIG. 2, another embodiment of the handlebar 1 with brake handles 6 is mounted in a different perspective view shown to a stem 2.

Here, too, the handles 3 form a closed, curved shape, which lie in the vertical plane Z.

The end 4 of the closed curved handle 3 is connected to the beginning 5 of the handle 3 positively and non-positively.

Here, the connection is a detachable such as screwing, plugging, clamping or similar. In this version, a normal handlebar stem 2 is selected.

Fig. 3 shows the handlebar 1 in a further embodiment in plan view, the closed curved shape of the handle 3 is achieved by retrofitting a curved segment 4 to a racing handlebar 1 at the joint 11 .

The end 4 of the handle 3 is positively and non-positively connected to the beginning 5 of the handle 3 . The connection can be a detachable example. It is formed from an additional tie 7 , which runs parallel to the central part 8 of the handlebar 1 ver. The straight pipe end 9 is extended to the neutral center 12 as a half-shell 10 . It encloses the middle part 8 . The connection is e.g. B. achieved by handlebar tape, heat shrink tubing, pipe clamps, steel tape, screws or the like.

FIG. 4 shows the example according to FIG. 3 in a side view.

In FIGS. 5 through 7, the three basic positions of the pre-suppression genes arm are shown, namely Fig. 5, the upright posture, Fig. 6, the bent posture, and in Fig. 7, the bent posture.
