Abstract

The bicycle headlight (1) has a housing (2) and a retainer (3) for attachment in a structure of a bicycle. The housing and the retainer are connected by a swivel-joint (4) with perpendicularly running axis of rotation (D). The housing at the rear side has contours (8) concentric to the axis of rotation. The contours (9) of the retainer run concentrically to the rotating axis and intervene according to the type of the nut and spring.

Description

The The present invention relates to a bicycle headlight having a casing and a holder for attachment to a structure of a bicycle.

typical Bicycle headlights have a holder on which the attachment on any structure of the bicycle in the front area allows. The Most of these brackets are adjustable by joints or the like so that the headlight can be aligned and adjusted in its inclination can. The known fastening systems are generally for a particular Fastening designed and do not allow great flexibility in the Choice of place of attachment.

The present invention employs dealing with the problem of having a bicycle headlight in the handlebar to fix. This results in the problem that a handlebar not necessarily exactly perpendicular to the direction of travel, but has a curved shape. One with a clamp attached to the handlebars Holder alone leads therefore not readily to an exact alignment of a bicycle headlamp in the desired Direction.

task The present invention therefore provides a bicycle headlamp with a housing and with a holder where the lateral orientation is easily adjustable is, but not easily adjusted after the setting.

to solution This object is achieved by a bicycle headlamp with the features of Claim 1. Advantageous embodiments are specified in the dependent claims.

Of the inventive bicycle headlamp has a housing and a holder for attachment to a structure of a bicycle on and is characterized by the fact that housing and holder via a swivel joint are connected with approximately perpendicular axis of rotation, wherein the housing at its back approximately concentric with the axis of rotation has contours, the in the manner of tongue and groove in concentric with the axis of rotation contours engage the holder. The housing the bicycle headlamp is therefore firmly on the holder and finds through the matching contours of housing and holder a secure support in every angular position of the adjustment range.

Of the entire area of the swivel joint is covered by side wings on the housing, so that it is not visible and well protected against external influences.

Housing and Holders are preferably by a hinge screw, as a rotary shaft serves, held together. This is preferably a Hexagon socket screw, which is inserted from below into the holder and in one in the case mounted nut engages. When tightening this screw will be contact surfaces of the holder and the housing pressed against each other, so that adjust the frictional forces in the pivot with this screw to let. Preferably, a setting is selected with frictional forces, the Although allow a lateral adjustment with a certain amount of force, but an unwanted change the setting of the bicycle headlight prevented.

Prefers the holder has to be attached to an approximately horizontal structure, in particular a handlebar, a quick release with a Strap and a tension lever on. Such closures are easy to attach and detach and allow precise adjustment of the vertical tilt of the bicycle headlight. For secure mounting of the bicycle headlight have housing and Holder preferably at least two intermeshing in the manner of tongue and groove Contours on.

One embodiment The invention, to which, however, is not limited, is hereinafter closer to the drawing explains and show:

1 a longitudinal section through bicycle headlights, housing and holder and

2 : a longitudinal section as in 1 but without bicycle headlight itself.

1 respectively. 2 show a bicycle headlight 1 with a housing 2 which with a holder 3 over a swivel joint 4 connected is. A hinge screw 5 serves as a propeller shaft and is from below in the holder 3 used. From above, the hinge screw 5 through one into the housing 2 employed mother 6 held. In the area of the hinge screw 5 have housing 2 and holder 3 contact surfaces 7 depending on the setting of the hinge screw 5 lie on each other with different friction. The housing 2 has contours on its back 8th on, in appropriate contours 9 on the holder 3 intervention. In the present exemplary embodiment, these are preferably contours 8th . 9 which engage in the manner of tongue and groove, and that at least two such corresponding contours. The whole swivel joint is through side wings 10 on the holder 3 are attached, covered. The holder has a quick release fastener 16 for attachment z. B. on a bicycle handlebar. The quick release fastener 16 indicates a warehouse 12 suspended strap 11 on which one about a camp 14 fixed clamps bel 13 can be stretched. This can be the end of the strap 11 for better accommodation through an opening in the clamping lever 13 be threaded. For better retention, the interior of the quick release closure 16 with a rubber pad 15 be provided, in particular at the same time as a cover for the hinge screw 5 serves.

After a single accurate adjustment of the position of the bicycle headlight 1 can the quick release fastener 16 opened and if necessary the hinge screw 5 tightened. Then you can the bicycle headlight 1 Quickly fasten and release the handlebar at the same place, without changing the position of the holder 3 changed.
