Description

The invention relates to a two-wheeler luggage carrier and a closing section therefor. In particular, the invention relates to a two-wheeler luggage rack with an integrated lighting and reflection unit.

Two-wheeler luggage carriers, in particular bicycle luggage carriers, are known in various designs. Known designs include a metal support frame with a central support section and a rear end section. It is known to provide mounting options for a rear light and/or a reflector on the rear end section. Also known are integrated rear lights, i. H. those that do not protrude separately, but fit into the contours of the supporting frame.

For example, shows the CN 210310676 U an LED rear light for a bicycle with an insertion tube connected to a frame.

WO 2020/091599 A1 discloses a bicycle rack with a receiving area for a module. A taillight is incorporated into a rear cross tube or, alternatively, may be mounted separately therefrom. A rear reflector is arranged externally on the luggage rack.

The DE 10 2006 018 447 A1 discloses a hollow plastic luggage rack for a bicycle. Equipment for a wide range of functions such as pump hooks, holders for reflectors and lights can be integrated into the luggage rack.

EP 0 933 290 A2 discloses a luggage rack for a two or three-wheeled vehicle with a storage container with a lid, a rear light receiving element and a counter-holder. The rear light receiving element is arranged at the rear end of a load-carrying body for receiving a self-radiating or reflective or combined self-radiating-reflecting rear light.

It can be considered an object to propose a two-wheeler carrier and a finishing portion for a two-wheeler carrier with a simple structure, capable of fulfilling safety functions with a pleasing design.

In view of the object, a two-wheeler luggage carrier according to claim 1 and an end section according to claim 19 are proposed. Dependent claims relate to advantageous embodiments of the invention.

The two-wheeler luggage rack according to the invention comprises a metal support frame, for example made of steel or aluminum. The support frame can, for example, consist of struts such as rods, tubes, profiles, plates or other forms of frame parts that are stably connected to one another so that the metal support frame can carry loads placed on or attached to it, e.g. in bicycle bags or Baskets, as well as, if necessary, a child in a child seat. While in some cases separable connections such as screw connections are possible, the frame parts are preferably inseparably connected to one another, e.g. by means of a one-piece design or material connection (e.g. welding, soldering).

The two-wheeler luggage rack comprises - understood in the longitudinal direction in the installed position on the two-wheeler - at least one central support section and a rear end section thereon, i.e. preferably the rear end. The rear end section is preferably also made of metallic material, more preferably made of the same metallic material as the central support section. The rear closing section is preferably inseparably connected to the central support section, for example formed in one piece or connected with a material bond. For example, the metal support frame may have at least two longitudinal struts and at least one transverse strut, and the rear termination portion may be arranged to connect the longitudinal struts.

The metal support frame can be manufactured together with the rear closure section, for example in an injection molding or die-casting process. Likewise, the rear end section can also be manufactured separately, preferably in an injection molding or die-casting process, and then connected to other frame parts. Thus, the closing section can be a separate part, so that the invention is also directed to the closing section as such. For connection to further frame parts, e.g. longitudinal struts, the final section can be connected to connecting elements, e.g engage in depressions or through depressions in which projections can engage. A high level of strength and mechanical stability can be achieved by such a form-fitting joint in conjunction with a material-to-material connection such as welding or soldering.

According to the invention, the rear end section has an increased height dimension compared to the central support section, ie the metal support frame is not over its length Equally developed, but higher at the rear end than in the middle (and preferably also than the front). The enlargement can be quite small; the height dimension of the rear closing section preferably corresponds to at least 1.5 times, more preferably at least 1.8 times, particularly preferably at least 2 times the height dimension in the central support section. The enlargement can take place in stages, but a gradual transition is preferred, for example in the form of an arc or a ramp.

According to the invention, a recess is formed in the rear closure section. An illumination and reflection unit is arranged in the recess. The lighting and reflection unit is thus arranged at least partially countersunk in the recess, preferably it can be arranged flush therein. This is preferably understood to mean that at the edges of the lighting and reflection unit, where it borders on the edges of the recess, the outer contour has no or only a very small height difference (of, for example, no more than 3mm, preferably 1mm or less), i. there is no or only a small step at the transition.

The lighting and reflection unit has a luminous surface and a reflector surface. The luminous surface is provided for the emission of light from illuminants, preferably a plurality of LED elements, which are distributed, for example, underneath the luminous surface, e.g shape and/or color it (e.g. red). The lens module can, for example, cause the light to be distributed over the luminous surface in order to obtain emission from the luminous surface that is as uniform as possible.

The reflector surface of the lighting and reflection unit effects a reflection of incident light, which is preferably an at least partially diffuse reflector, i.e. incident light is also at least partially scattered and not specularly reflected.

The two-wheeler luggage rack according to the invention thus enables a mechanically favorable and optically pleasing integration of a lighting and reflection unit, which enables both active lighting and passive reflection and thus ensures good visibility of the two-wheeler from the rear. Due to the increased height dimension, a larger area is available for the arrangement of the lighting and reflection unit. In this way, a sufficient area can be used both for reflection and for lighting, without having to forego at least partial integration in the final section.

The luminous surface and the reflector surface can be formed on a common part or formed on two or more separate parts, which are preferably fastened together to form the lighting and reflection unit. The part or parts can be made of plastic, for example, and/or be produced using an injection molding process. The parts are preferably at least partially transparent.

According to a preferred embodiment, in the case of a metal support frame with longitudinal struts, these can form a section that is increased in height in the region of the rear end section compared to the central support section. That is, the increase in the height direction is preferably present not only in the transverse direction but also over at least a short portion in the longitudinal direction. The recess, which preferably extends over the entire width of the rear end section, can particularly preferably extend into an at least partially longitudinal section, for example from the rear end section to both longitudinal struts. In this way, the lighting and reflection unit can extend around the rear corners of the metal support frame. This allows a favorable orientation for better visibility and/or illumination from the side.

The recess can, for example, extend over a height that corresponds to at least 50% of the height of the rear closing section, preferably at least 60%, particularly preferably at least 70%. In this way, the largest possible area is available for the lighting and reflection unit. The recess can preferably have a depth of at least 8 mm, so that there is sufficient installation depth.

The reflector surface and the luminous surface can be arranged in relation to one another in different ways, for example as a plurality of alternating reflector and luminous surface sections. The reflector surface can be in the form of a strip, i.e. it can have a significantly greater length than the width. The reflector surface can be delimited by parallel edges, for example in the form of a rectangle or trapezium, preferably with rounded corners. According to a preferred embodiment, the reflector surface can be arranged partially or also entirely contiguously inside the luminous surface and surrounded by it.

In total, the reflector surface can have an effective surface area of at least 800 mm ² for reflection, so that a large surface area is available to achieve high reflection.

For example, the reflector surface can be designed in such a way that it has the following minimum reflection values:

• at an observation angle α = 1/3°, at a horizontal incidence angle βH=0° and vertical βV=0°: 1000 mcd/lx,
• at an observation angle α = 1/3°, at an illumination angle horizontal βH=0° and vertical βV=±10° : 700 mcd/lx,
• at an observation angle α = 1/3°, at a horizontal incidence angle βH=±20° and vertical βV=±5°: 400 mcd/lx,
• at an observation angle of α = 1.5°, with an illumination angle of βH=0° horizontally and βV=0° vertically: 30 mcd/lx,
• at an observation angle α = 1.5°, at an illumination angle of βH=0° horizontally and βV=±10° vertically: 20 mcd/lx, and
• at an observation angle α = 1.5°, at a horizontal incidence angle βH=±20° and vertical βV=±5°: 10 mcd/lx.

According to a preferred embodiment, a slit connected to the recess can be formed at the rear termination section. The slit penetrates the material of the rear end section and thus allows part of the light generated by the lighting and reflection unit to also be emitted through the slit, preferably in a different direction than the rest of the light emitted by the luminous surface. For example, the slit can be aligned downwards and thus enable a portion of the light to be emitted downwards, for example to illuminate the floor or parts of the two-wheeler.

1 shows a bicycle luggage carrier 10 as an example of a bicycle luggage carrier in a plan view. The luggage rack 10 comprises a support frame 12 made of metal, in the example shown made of aluminum using the die-casting process. The luggage rack 10 also includes supports and struts, not shown here, which are connected to the support frame 12 and are intended for attachment to a bicycle.

The support frame 12 comprises two parallel longitudinal struts 12a, which are connected to one another in the transverse direction by transverse struts 12b. At the front (in 1 shown below) the support frame 12 is closed by a front closure 18, at the rear end (above in 1 ) by a rear closing section 16. This is formed with a transversely extending section 24 and two longitudinal sections 26 adjoining it after rounded connections 28 and merging into the longitudinal struts 12a.

In the longitudinal direction of the luggage carrier 10, the rear closing section 16, which in the example makes up about a quarter of the length of the luggage carrier, adjoins a central carrying section 14 of the luggage carrier 10.

2-5 12 show the rear termination section 16 according to a first embodiment in different views. Like the rest of the support frame 12, the rear connection section 16 is made of metal, here also die-cast aluminum. In the example shown, however, the support frame 12 is not formed in one piece, but rather the longitudinal sections 26 of the rear closing section 16 are welded to the remaining part of the longitudinal struts 12a. The welded connection is additionally supported by receiving pins 40 in corresponding recesses on the longitudinal struts 12a.

The rear termination section 16 has, as in 3 shown a height H2 that is greater than a height H1 of the support frame 12, here the longitudinal struts 12a, in the central support section 14. The increased height H2 applies to the transverse section 24 and the rounded ends 28 connected to the longitudinal Sections 26 of the rear end section 16. In the longitudinal course of the longitudinal In sections 26, the height decreases in an arcuate transition section 42. In the example shown, the height H2 corresponds to approximately 2.3 times the height H1.

A recess 20 is formed in the rear closing section 16, the shape of which can be seen in particular from the exploded view in FIG 6 is clearly visible. The recess 20 extends over the entire length of the transverse section 24 into the longitudinal sections 26.

An illumination and reflection unit 30 is accommodated in the recess 20 . The lighting and reflection unit 30 completely fills the recess 20 so that the outer surface is flush with the rear closing section 16 of the support frame 12 .

As in 6 shown, the lighting and reflection unit 30 is constructed with a plastic housing 44, an LED strip 46 arranged therein with LEDs 38 arranged spaced apart in a row, a lens element 48 and a reflector surface 34. The LED strip 46 is controlled by a controller (not shown) is connected to a source of electrical power so that the LEDs 38 can be operated. The light emitted by these is transmitted through the lens element 48 and emitted on its outer luminous surface 32 . The lens element 48 causes the light to be scattered and colored red, so that red light is emitted via the luminous surface 32 both to the rear and to the sides.

In the rear closing section 16, for example 5 , 6 As can be seen, a downwardly directed slot 22 is formed, which penetrates the rear end section 16 and is connected to the interior of the recess 20 . The light of the LEDs 38 is also emitted through the slit 22 in a vertical downward direction, so that parts of the bicycle and the bottom thereof are illuminated.

The lighting and reflection unit 30 thus fulfills the function of a rear light for a two-wheeler, in particular for a bicycle, by which both conventional bicycles and electric bicycles are to be understood. In addition, the lighting and reflection unit 30 also fulfills the function of a reflector due to the large reflector surface 34 . As for example from the rear view in 4 As can be seen, the reflector surface 34 extends in strips along the transverse section 24. The reflector surface 34 is surrounded by the luminous surface 32. The reflector surface 34 is quite large with an effective reflecting surface of approx. 950 mm ² , for this purpose it extends in the transverse direction over approx. 70% of the width of the rear closing section 16 and in the height HA over approx. 80%. from the height H2 of the rear termination section 16.

The lens element 48 is preferably formed from transparent (red) plastic using a plastic injection molding process. While in the example shown the lens element 48 and the reflector surface 34 are designed as separate parts of the lighting and reflection unit 30, which are permanently attached to one another, e.g. by gluing or molding/injecting, the lens element 48 with the reflector surface 34 can be used in an alternative embodiment also be formed in one piece (not shown separately).

The lighting and reflection unit is fully contained within the recess 20 so as to allow for the flush arrangement shown. For this purpose, the recess 20 has a maximum depth of slightly more than 13 mm along the transverse section 24 and a depth of approximately 10 mm along the longitudinal sections 26 .

7 12 shows an alternative rear termination section 116 according to a second embodiment. The termination section 116 according to the second embodiment largely corresponds to the termination section 16 according to the first embodiment. Therefore, only the differences are explained here. In this case, the same reference symbols designate those elements which both embodiments have in common.

The rear closing section 116 according to the second embodiment comprises a differently shaped transverse section 124 between the longitudinal sections 26 which merge into the longitudinal struts 12a (not shown) of the support frame 12 . In addition to the transverse section 24 of the first embodiment, this includes an additional transverse connection between the longitudinal struts 12a. For the rest, however, the embodiments agree.
