Description

The present invention relates to a bicycle comprising a handlebar having at its ends a handle, a bicycle bell on the handlebar, with a bell and a hammer mechanism for sounding the bell, which hammer mechanism can be driven with a handle, the handle being a body is with therein a matching with the bicycle handlebar passage which is rotatable about the bicycle handlebar.

Such a bicycle with a bicycle bell is well known, being used as a handle which is rotatably mounted on the bicycle handlebar ( DE 804 760 B . DE 850 557 B ).

A disadvantage of the known technique is that the freely rotatable attachment of a handle to the handlebar with such freedom that the sounding of the bicycle bell can be made sufficiently fast results in a very dangerous situation. The resting on the handlebar during cycling and in particular on its handles can lead to the turning away of the handle, which is used as a lever for the bicycle bell. In this situation, a cyclist can tilt forward over the handlebars. The risks are not limited to physical injuries of the cyclist alone: Traffic safety in general is endangered.

A bicycle according to the invention is defined in claim 1; the dependent claims relate to advantageous Augestaltungen. According to the present invention, a bicycle has been accomplished according to claim 1, the u. a. differs in that the handle is independently rotatable by the handle. The handle is probably still rotatable about the longitudinal direction of the bicycle handlebar, but with the independence of the handle, the rotation of this handle is not possible, so that the safety for the cyclist and road safety have generally been improved.

In a first embodiment, the passage is opened on both sides so that the bell can be placed next to the handle in such a way that the drive handle, as it were, merges into the handle.

Furthermore, a bicycle according to the present invention has the characteristic that at least two hammers are arranged in the space defined by the bell, and the hammer mechanism selectively drives each hammer separately depending on the direction of rotation of the handle. In this way, a bell hammer has been made for each direction of rotation, so that the configuration thereof can remain very simple.

In a preferred embodiment, a bicycle according to the present invention has the property that the bell and the counter-bell connect to each other at a distance from the respective passages without contact. Visually, a closed whole is thus created, which is pleasant to hold and has a beautiful appearance. In a related embodiment, the counter shell extends completely or partially along the outer surface of the bell so that the counter shell offers protection to the bell to some extent. This is particularly advantageous when a plastic counter bell is used, which may be better resistant to damage than the bell itself, which bell may possibly be made of metal. In this case, the counter bell must have openings that let out the sound generated by the bell, so that this signal is not attenuated. The shape of the part of the counter bell closing over the bell may be that of a grid or grid.

The present invention will be explained in more detail with reference to the following description of the figures, taken in conjunction with the attached figures, in which:

1 a perspective view of a part of the bicycle with a bicycle bell according to the present invention;

2 a perspective view of a portion of a bicycle according to the present invention with the bicycle bell at a location other than in the 1 is;

3 a partially broken perspective view of the in the 1 and 2 shown bicycle bell is;

4 a sectional view taken along the line IV-IV of 3 is

5 a view of an alternative embodiment of a bicycle bell according to the present invention shows; and

6 a perspective view accordingly 1 is for a bicycle with chain gear shift.

In the 1 a detail of the bicycle according to the present invention is shown in the perspective view, wherein the bell 1 near the handle 7 on the handlebar 3 is appropriate. The bell 1 includes a bell jingle 4 and a handle 5 where the handle 5 serves to drive a mechanism to be described below to ring the bell.

The handlebar 2 sticks out of the frame 6 out of the bike, taking at the ends of the handlebar 3 the handles 7 are attached. Near the handles 7 are on the handlebars 3 also lever 8th attached to the operation of the brakes, which are not shown here incidentally.

As stated, the bell will ring 1 by twisting the handle 5 opposite the bell jingle 4 operated, said mechanism inside the construction of the bell 4 and the handle 5 the bell 4 strikes, thus the bell 1 to sound.

With the other handle 7 is located on the handlebars 3 an operation 38 for the gearshift of the bicycle. It is a simple mechanism and thus it will be a bicycle with a hub gearshift. The bell 1 and the operation 38 have the same exterior, bringing the aesthetic effect of the bicycle resulting in the symmetry of the uniform bell 1 and the operation 38 has been increased.

In the 2 is one with the 1 matching view, with the bell on one of the handles 7 is appropriate. The handle in question 7 is from the bell 1 independently. This implies that a cyclist is calm on the handles 7 without worrying that they will twist and the cyclist will get out of balance. This could in fact result in the cyclist being on the handlebars 3 crashes or in general constitutes a hazard to traffic safety. The handles 7 are therefore basically stuck with the handlebar 3 connected. Here is no operation for a gear shift attached; It will therefore be a bicycle with coaster brake.

Rotation of the handle 5 the bell 1 also goes with a torque on the handlebars 3 opposite the handlebar 2 associated. Because the rotary motion of the handle 5 is located in a plane that is at least nearly parallel to the direction of the handlebar 2 is located, this torque will be low.

The in the 3 shown view of the bell 1 corresponds to that in the 2 shown situation.

The bell 1 is from a socket 9 , a sleeve 10 , a ring 11 , the bell ring 4 and the handle 5 built up. The sleeve 10 is in the socket 9 plugged in, with the free end of the sleeve 10 with a raised edge 12 is provided. The bell ring 4 is between these upstanding edges 12 and one side of the ring 11 sandwiched, the other side of the ring 11 at the end of the rifle 9 rests under which the sleeve 10 has been inserted through.

To the rifle 9 around are freely rotatable wreaths in one direction 14 attached to what hammer 13 are attached. In the field of wreaths 14 is the rifle 9 with block-shaped projections 15 provided, which extend in the axial direction. The projections 15 make up together with stops 16 at the wreaths a lock against rotation of the wreaths in separate directions around the sleeve 9 around. This will be described in detail below.

The handle 5 consists of a substantially conical body 17 with a disguise 18 , which is made of plastic, for example, to optimize the grip of the handle.

The conical body 17 diverges against the rifle 9 in the direction of the bell bell 4 to a the scope of the bell ring 4 corresponding scope. The bell ring 4 cant over the gavel 13 opposite the rifle 9 addition, being attached to the body 17 block-shaped tensioner 19 are attached, extending to below the bell ring 4 extend. The hammer 1 are by flexible thighs 20 with the wreaths 14 connected.

When twisting the handle 5 the tensioner beats 18 to the hammer 13 on and especially on the foot 21 of the hammer 13 , Upon further movement of the body 17 is due to the shape of the foot 21 of the hammer 13 the thigh 20 bent and becomes the hammer 13 inside relative to the bell ring 4 bent. As soon as the handle 5 and as a result the tensioner 19 has moved so far that the hammer 13 will be free again, this will ring the bell 4 which generates the ringing signal. The conical body 17 is about the rifle 9 rotatable, being on the conical body 17 hook 23 attached to the groove 22 in the box 9 intervention. Thus, the conical body can 17 not or hardly move in the axial direction and its freedom of movement is essentially on a movement around the sleeve 9 limited.

Around an arrangement like the one in the distance from the handle 7 it is possible to effect at least the rifle 9 and the sleeve 10 Made of reasonably supple material, so that the bow in the handlebar 3 can be done.

The construction of rifle 9 , Sleeve 10 etc. is done by means of the clamp 24 held together with a screw or a bolt 25 can be strengthened. In the conical body 17 is a passage 26 attached, through which a tool can be inserted, such as a screwdriver or a hexagon socket to the screw or the bolt 25 tighten or loosen. Thus, the rifle forms 9 a loop around the handlebars 3 can be attached.

In the in the 4 shown sectional view along the line IV-IV of 3 they are at the two wreaths 14 attached hammer 13 shown. Every one of these hammers 13 serves to ring the bell when the handle is twisted 5 in one of the two possible directions of rotation of the same.

When twisting the handle 5 in the direction corresponding to the arrow A, the tensioner moves 19 over the sloping surface of the foot 21 and thus forces the thigh 20 to bend, taking the hammer 12 inward relative to the bell ring 4 is adjusted. When the tensioner 19 over the outermost point of the foot 21 has been moved out, comes the thigh 20 as a result of its flexibility or elasticity back to its original position. This beats the hammer 13 to the bell ring 4 on, whereby the ringing signal is generated.

Twisting of the wreath 14 on which the thigh 20 is attached, it prevents the stop 16 in the direction corresponding to the arrow A behind a block-shaped projection 15 hooked. The stop 16 is made of resilient material but stiff enough to ensure proper locking.

In the opposite position remains the foot 21 ' of the hammer 13 ' on the thigh 20 ' behind the tensioner 19 ' hook and is taken away. This advancing motion is over the thigh 20 ' on the wreath 14 ' transmitted, which is freely rotatable in the direction corresponding to the arrow A, by the relative position of the to the garland 14 ' belonging stop 16 ' opposite the block-shaped projections 15 , In this way, the stop will be 16 over the block-shaped projections 15 pulled away and is movement of the wreath 14 ' in the direction corresponding to the arrow A readily possible.

The reverse applies to movement of the handle 5 in the direction indicated by the arrow B, the hammer 13 ' with the foot 211 to the bell ring 4 strikes while the hammer 13 with the foot 21 from one of the tensioners 19 is pulled along.

In the 5 shown bicycle bell 27 is also on a handlebar 3 on a handle 7 attached. The bell consists of a handle 28 which is designed here as a ring substantially around the handlebar. Again, the handle 28 according to the in the 3 shown handle 5 cladded with a covering, such as rubber, whereby the grip can be optimized for the user's hand.

The handle 28 go in the direction of the bell ring 29 from the bell 27 out in a wreath 32 with projections 31 out, with the wreath 32 in a housing 30 is appropriate. The housing 30 forms a unit with the bell jingle 29 Opposite counter bell 33 , the bell ring 29 from the counter bell 33 is worn and thus at a distance from the handlebar 3 is held.

A hammer 35 to sound the bell 27 is on a dump truck 36 attached, which has a tipping point 34 can be tilted away. That the hammer 35 opposite end of the dump truck 36 is with a contact part 37 provided, for example, under spring force on the surface of the wreath 32 is held, where also the projections 31 are located. Thus, the running of the contact part 37 over the projections 31 of the wreath 32 upon rotation of the handle 28 over the tipping point 34 on the hammer 35 transfer. Thus, the hammer 35 the bell ring 29 with every movement of the contact part 37 on the tilt support 36 about a lead 31 of the contact wreath 32 strike like this one with the handle 28 connected or is an integral part of.

The in the 5 embodiment shown has the advantage that under the bell ring 29 the corresponding counter bell 33 on the handlebar 3 Room remains to here usual controls on the handlebars 3 to attach, such as a brake or a gearshift operation.

The above is in the 6 shown for a bicycle with a chain gear shift, the two controls 38 requires, close to each handle 7 a. The operations 38 with two operating heads each 39 each form a unit with the brake levers 8th , where in the 5 shown configuration of the bell 1 It allows one of the operations 38 under the bell ring 4 has been attached, without the ease of use of the bell 1 or the operation 38 the gearshift or the brake handle 8th to affect and thus a very compact configuration has been obtained.

Having noted the foregoing, many alternative embodiments will be apparent to those skilled in the art. However, these alternative embodiments are to be understood as being within the scope of the present invention as defined in the appended claims. Thus, the execution of the drum mechanism in several other ways possible than in the, in particular in connection with the 3 . 4 and 5 has been described. It is also possible, the (in itself stationary) rifle 9 as a unit with the handle 7 to shape, which also when twisting the handle 5 should remain immovable. Other embodiments are possible.
