Description

The invention relates to a pull-out guide for a rear carrier arrangement with the features in the preamble of the main claim.

Such a pull-out guide for the support body of a rear carrier arrangement is from DE 10 2009 057 651 A1 known.

The DE 43 40 009 A1 teaches a car rear transport bridge for transporting bicycles with a vehicle-mounted guide and a tilt-proof, extendable support shelf.

The ones in the DE 10 2004 008 530 A1 and the DE 10 2004 021 709 A1 The pull-out guide shown has two parallel guide means in the form of telescopic rails and is arranged in the rear area of the vehicle body. The extension and guiding direction is linear and horizontal. The support means of the rear carrier arrangement are designed as swivel arms and mounted on the support body.

The DE 10 2012 105 857 A1 discloses another pull-out guide with a vertical orientation for raising and lowering a support body.

From the DE 103 38 723 A1 A pull-out guide with parallel links as guide means is known. As a result, a support body can be pivoted from a rest position below the vehicle floor into an operating position.

The DE 10 2004 007 816 A1 shows another linear and horizontally aligned pull-out guide for a rear carrier arrangement.

At the DE 10 2012 008 124 A1 Two parallel and pivotable ball head couplings are arranged at the rear of the vehicle, on which a load carrier can be picked up and supported.

It is the object of the present invention to demonstrate an improved drawer guide.

The invention solves this problem with the features in the main claim.

The claimed pull-out guide provides for the assignment of a tilting protection to the parallel and extendable guide means. This allows the support body to be moved back and forth more easily between a retracted rest position and an extended operating position. In the simplest case, this can be done manually. In a comfort version, a drive can be provided for the movements of the support body. The drive can be operated and, if necessary, controlled by a switch or a wireless remote control.

The guide means are each assigned a toothed strip which meshes with a pinion, the pinions being arranged in a rotationally fixed manner on a common shaft. If necessary, the shaft can be connected to the drive. This ensures a uniform extension and retraction movement of the guide means and prevents tilting.

The toothed strip is preferably formed onto a strip-shaped guide element of the guide means. This optimizes the guidance function and anti-tilt protection. Furthermore, the construction and space requirements are reduced. In addition, a particularly good and kinematically favorable allocation of guide and groin areas is possible.

The guide means include a curved and upwardly directed guide area at the rear end of the guide track. In a particularly preferred embodiment, the guide means designed as a guide bar has at least one curved guide area, the toothed bar also having a curved bar area. These curved areas can be adapted to one another. This design allows the orientation of the support body to be changed during the retraction and extension movements as well as in the rest and operating positions.

This is favorable for the design and function of a suspension element of the rear carrier arrangement. The carrying means can be, for example, a load carrier, in particular a bicycle carrier, a box carrier or the like. If necessary, the suspension element can be connected to the support body in a detachable manner, for example being docked and undocked via a predetermined interface. In another variant, the support means can be connected to the support body and, if necessary, moved, in particular pivoted, into a supporting position. This can, for example, be a design according to DE 10 2004 008 530 A1 or DE 10 2004 021 709 A1 be.

The invention relates to a pull-out guide (8) for a rear carrier arrangement (4) for a vehicle (1), in particular a road vehicle. The invention further relates to the rear carrier arrangement (4).

How 1 and 2 To illustrate, the rear carrier arrangement (4) is arranged at the rear area (3) of a vehicle (1). The vehicle (1) is a motor vehicle, in particular a road vehicle, for example a car or truck. The pull-out guide (8) is intended for a support body (5) of the rear carrier arrangement (4), which is located between an in 1 shown retracted resting position and one in 2 shown, extended operating position can be moved back and forth by means of the extension guide (8).

The pull-out guide (8) can be an independently manufactured and tradeable component. It can be part of a rear carrier arrangement (4), but this is not absolutely necessary. If necessary, it can be retrofitted to vehicles (1). It can also be used to convert existing rear carrier arrangements (4). The pull-out guide (8) can alternatively be an integral part of a vehicle (1) and/or a rear carrier arrangement (4).

The rear carrier arrangement (4) can also have a support means (6), for example a load carrier, which can be permanently or detachably connected to the support body (5). The suspension element (6) can be rigid or movable, in particular according to DE 10 2004 008 530 A1 or DE 10 2004 021 709 A1 be designed to be foldable. A lighting arrangement can also be mounted on the suspension element (6), which can be connected to the vehicle electrical system (1) in a suitable manner.

The pull-out guide (8) and the support body (5) are arranged, for example, in the floor area of the vehicle (1), in particular below the vehicle floor. The pull-out guide (8) and the support body (5) have an essentially horizontal arrangement.

In another variant, not shown, the pull-out guide (8) and the support body (5) can have an upright or standing arrangement and can be arranged hidden in the rear area behind the rear bumper or behind the rear apron. The pull-out guide (8) can have the same or at least similar design in these different variants.

The pull-out guide (8) has several guide means (9, 10) that can be pulled out in parallel. An anti-tilting device (15) is assigned to the guide means (9, 10). It ensures that the guide means (9, 10) and the support body (5) move in and out without tilting.

The guide means (9, 10) are arranged between the support body (5) and a frame (7), which can be connected to the vehicle (1), in particular its chassis (2). The frame (7) can have longitudinal and/or cross members. It is in 1 and 2 indicated schematically.

The guide means (9,10) are present several times and are arranged parallel to one another. In the exemplary embodiments shown there are two parallel guide means (9, 10).

The guide means (9,10) each consist of guide elements (11,12) that interact in a form-fitting manner. On the one hand, this is an elongated guide element (11) that defines the guide track and is designed, for example, as a guide bar. The other guide element (12) is designed as a rolling and/or rolling element and can be present multiple times. The guideway can be defined by a rail or a web on the guide element (11), on which the guide elements (12) engage on one or more sides. In the exemplary embodiments shown, the guideway is designed as an elongated groove into which the rolling or rolling elements engage in a form-fitting manner and are guided here in the direction of the path.

In the exemplary embodiments shown, the web-shaped or strip-shaped guide elements (11) are arranged in a stationary manner and fastened to the frame (7). They extend on the outside and on both sides of the support body (5). In the exemplary embodiments shown, they are arranged lying and on or below the floor area of the vehicle (1). The rolling guide elements (12) are arranged on the support body (9). This assignment of these guide elements (11, 12) to the support body (5) and to the frame (7) can also be reversed.

How 3 clarified, the pull-out guide (8) has, in addition to the guide means (9, 10), also toothed strips (18, 19) and pinions (22, 23) that mesh with them. The pinions (22,23) are synchronized with each other. In particular, you can have an opposite have a rotationally tight connection. The pinions (22, 23) are arranged in a rotationally fixed manner on a common shaft (24) and are therefore synchronized.

A toothed strip (18, 19) is each assigned to the guide means (9, 10). The assignment can be designed differently. In the preferred embodiments shown, the toothed strip (18, 19) is arranged on a guide element (11). It is preferably formed on the guide element (11).

In the embodiment shown 3 the pullout guide (8) also has a drive (14). This is connected to the pinions (22, 23) and drives them. The drive (14) can be switched on and off and controlled if necessary. With the drive (14), the support body (5) can be moved between the rest and operating positions by motor and remotely. In the case of an alternative manual operation, a handle or the like can be arranged on the support body (5).

In one or more positions, in particular in the extended position, the support body (5) can be provided by an in 2 schematically indicated lock (13) can be fixed mechanically. This supports the loads on the rear carrier arrangement (4) that occur when driving.

The drive (14) can be designed in any suitable manner. In the exemplary embodiment shown, it has a motor (25), which is preferably designed as an electric motor, in particular as an electric geared motor. This can be a DC motor that can be operated with the on-board voltage of the vehicle (1). The drive (14) can also have an intermediate drive (26) for connecting the motor (25) to the pinions (22, 23), in particular to the common shaft (24). The intermediate drive (26) is formed, for example, by a large gear on the output shaft of the motor (25) and a smaller pinion on the shaft (24) as well as a drive belt, in particular a toothed belt. Alternatively, a direct drive of the pinions (22, 23) or the shaft (24) is possible. The drive (14) can alternatively be designed as a fluid drive, for example as a cylinder or in some other way.

In the exemplary embodiments shown, the drive (14) is located on the support body (5) and is suitably supplied with operating energy, in particular electricity, and control signals via a trailing cable or the like. Alternatively, the drive (14) can be arranged on the frame (7), with the assignment of the guide elements (11, 12) being reversed.

The guide means (9,10) have at least one curved guide area (17). Alternatively, a multiple arrangement is possible. The curved guide area (17) can have one or more radii of curvature. This allows the orientation of the support body (5) to be changed during the retraction and extension movement. The guide means (9, 10) can also have at least one straight guide area (16). A multiple arrangement is also possible here.

How 1 and 2 To illustrate, the support body (5) assumes an essentially parallel position to the vehicle floor or to the ground in the retracted rest position. The curved guide area (17) is located at the rear end of the guide track and is directed upwards. As a result, the support body (5) assumes an obliquely upward position in the extended operating position. As a result, the support means (6) of the rear carrier arrangement (4), which is connected or connectable to the support body (5), can have sufficient ground clearance.

The angle of curvature of the curved guide area (17) can be chosen arbitrarily. It can be up to 90° and more. A large angle of curvature is selected, for example, if the support body (5) in an embodiment not shown is to be brought from a substantially vertical rest position into a substantially horizontal or obliquely upward extended operating position. The length of the curved guide area (17) can also be selected. In the exemplary embodiments shown, the curved guide area (17) is located on the track- or strip-shaped guide elements (11).

How 3 , 4 and 5 To illustrate, the toothed strips (18, 19) also have at least one curved strip area (21). They can also have a straight strip area (20). The curved strip area (21) is adapted to the shape and arrangement of the curved guide area (17). The design of the curved strip area (21) can also depend on the relative position of the engaged pinion (22, 23) to the guide elements (12).

Due to the curved strip area (21), the anti-tilting device (15) and the drive (14) can also be effective with a curved guideway and define the support body movement.

The pinions (22, 23) and the toothed strips (18, 19) are provided with spur teeth in the exemplary embodiments shown. The teeth can have an involute shape. Under pinions and The invention refers to toothed strips as all positive drive connections between a rotating body and a strip body. This includes other forms of gearing, for example with knobs and holes, rack gearing or the like.
