The invention relates to a handle for releasable attachment
on a tubular rod, in particular a handlebar grip
for the handlebar of a vehicle such as preferably a bicycle,
with a handle body, which has a cylindrical opening
for pushing the handle body onto a pipe outer casing
a rod, and with a fastening means for
releasably locking the handle body to the rod.
A generic handlebar grip is from the DE 298 01 916 U1
known. In the generic handlebar grip, the grip body consists of a slotted sleeve whose outer end is provided with a serving as Abrutschsicherung thickening, which is provided substantially tangentially with a threaded bore for receiving a clamping screw. The setting of the generic handle is done by screwing the clamping screw into the threaded hole and by reducing the slot gap of the slotted sleeve. On the outer circumference of the slotted sleeve, a grip rubber is glued so that the user is not irritated by the clamping slot in the sleeve when gripping the handlebar grip.
An ergonomically shaped handlebar grip is out of the EP 1 373 058 B1
known. The asymmetrical to improve ergonomics handlebar grip is secured to the rod by means of two sockets by frictional engagement, wherein the first plug is mounted before pushing the handle body and the handlebar center faces, while the second socket forms a final element. Both sockets have a cylindrical outer portion, which is provided with elastically compressible cover layers, which are to apply in the assembled state, the necessary Reibdruck between outer tube shell and handle body to prevent twisting of the mounted handle. To increase the frictional force, ribs may be formed in particular on the plug-in sleeve forming the closing element. For disassembly, the frictional force must be overcome to first remove the end member from the pipe end and then remove the handle body from the rod.
The invention is a handle with improved attachment means
to create, which creates a secure grip for the handle
and allows the handle to move quickly and with less
Assembly costs can be solved.

Advantages and embodiments of an inventive
Griffs will be apparent from the following description of a in
the drawing schematically shown embodiment
for an inventive, ergonomic
Handle. In the drawing show:
1 in plan view a handle according to the invention in the assembled state at a handlebar end;
2 a horizontal section through the handlebar-mounted ergonomic handle according to 1 ;
3 in exploded view, a handle according to the invention with disassembled fastening device in the initial state; and
4 in exploded view the handle according to 3 with widened clamping body.
In the figures, reference numeral is in total 50 an inventive ergonomic handle refers to the tubular handlebar 1 a bicycle, not further shown od. Like. Is attached. The ergonomic handle 50 has a handle body 10 on, extending from one of the middle of the handlebar facing handle 2 to a relatively wide grip body end 3 widened, in particular in this widened region of the handle body end 3 an asymmetric and in the assembled state shown horizontal and the user of the bicycle facing palm rest 4 is trained. A user of the bicycle can while gripping the handle 50 his palm on the palm rest 4 Hang up, especially during a long drive a relaxed Griffhal to take over. The attachment of the handle body 10 via a fastening device 20 connected to the cavity of the handlebar 1 interacts and from the in 1 only an outer end element 21 , which preferably consists of dimensionally stable plastic, is shown.
The 2 shows a horizontal section through the handle 50 and the 3 and 4 show the handle body 10 the handlebar grip 50 and the fastening device 20 in disassembly state. From all 2 to 4 it is obvious that the handle body 10 a basic body asymmetrical in cross-section 5 having a cylindrical opening in an overall thicker portion 6 has, whose diameter is adapted to the outer tube shell 1' of the handlebar tube 1 to be deferred. Here, the game between the cylindrical opening 6 in the main body 5 of the handle body 10 and the outer tube shell 1' advantageously already form a transition fit, so that the handle body 10 from the beginning with a certain firmness on the pole 1 is mounted. The torsion-proof locking of the body 5 and the handle body 10 on the pole 1 However, this is done via the fastening device 20 , which as an essential element a clamping body 22 that is in the cavity 7 inside the tubular rod 1 is inserted and the locking and fixing the handle body 10 expandable in the desired mounting position. The different thicknesses of the clamp body 22 can take a, clarifies a comparison of 3 with the unsuspected clamp body 22 and 4 with the widened clamping body 22 ' , The widening of the clamp body 22 takes place by an axial movement of a pressure ring or pressure plate 28 relative to the closure element 21 , which in the assembled state with a substantially flat base 23 at the front 5 ' of the basic body 5 of the handle body 10 is applied. The axial movement of the pressure ring 28 is by means of a preferably on the axis A of the pipe rod 1 arranged adjusting screw or actuating screw 24 achieved, the z. B. can be rotated by means of an Allen key. The screw head 25 the actuating screw 24 is freely rotatable and sunk in a recess 26 in the final element 21 , For better guidance and centering of the end element 21 in the cavity 7 the pole 1 jump over the base 23 of the final element 21 a here on the plastic part molded centering 27 before, the outer diameter substantially to the inner diameter of the pipe rod 1 is adjusted. The clamp body 22 lies in the assembled state between the middle of the handlebar center facing end face 27 ' of the centering pin 27 and the final element 21 facing inner surface of the pressure ring 28 , The actuating screw engages with its externally threaded shank in a particular trained as a through hole threaded hole 30 in the pressure ring 28 one. Will the actuating screw 24 turned in one direction, moves the interaction of thread on the shaft and threaded hole 30 the pressure ring 28 , reducing the distance between the pressure ring 28 and the face 27 ' is reduced to the existing preferably elastic rubber material clamping body 22 sufficiently wide and the final element 21 the fastening device 20 in the desired position and orientation in the cavity of the rod 1 secure against rotation. In order to prevent in this situation that the basic body 5 of the handle body 10 can move relative to the final element, in particular can be twisted, jumps over the base 23 of the final element 21 , here eccentric to the axis position of the actuating screw 24 , a sufficiently strong locking pin 29 before, in a suitably designed for a positive engagement recess 8th in the front side 5 ' of the basic body 5 surrounds. The release is correspondingly reversed.
Between the pressure ring 28 and the clamp body 22 suitable friction linings od. Like. Arranged or formed, as an additional rotation-preventing means relative rotation between the pressure ring 28 and the clamp body 22 to prevent any adjustment movement of the actuating screw 24 safely in an axial position change of the pressure ring 28 is implemented. Corresponding anti-rotation means could additionally also between the clamping body 22 and the centering pin 27 be educated. Furthermore, the scope of the clamp body could also 22 be provided with a friction lining, rough surface or other measures to the frictional engagement between the clamping body 22 and inner shell of the rod increase.
In the embodiment shown, the entire surface of the handle body 5 with a thin, compressible coating 9 provided while the main body 5 preferably consists of a dimensionally stable, incompressible plastic material.
Those skilled in the art will recognize from the foregoing description numerous modifications which are intended to be within the scope of the appended claims. The widening of the clamping body could also be effected by means of a spreading element or the like. The rotation between the end element and the main body of the handle could also be done via a plurality of pin protrusions. In a total round handle body could regularly or irregularly distributed over the circumference several locking projections od. The like. Be formed, which border in corresponding recesses. The projections or the one projection could also be formed on the handle body, the ent enclosing speaking depressions in the final element. Instead of a clamping body and several clamping body could be used to provide additional protection against loosening of the handle. The handle body toward the center of the handlebar by a handbrake handle, circuit grip or the like. Or be secured in another way against axial movement.
