Description

[0001] The invention relates to a vehicle with at least one cargo compartment flap closing a rear cargo area and an extendable loading floor according to the preamble of claim 1.

[0002] A vehicle of this type (pick-up truck) with a load floor of an open cargo bed that extends beyond its loading edge is known from US 7,699,373 B2 and US 2009 / 0195007 A1. The two tailgates of the open cargo bed, each pivoting about an axis of rotation directed upwards in the direction of the vehicle, have guide grooves at their lower edge and running parallel to it, so that in the 90 0With both tailgates open, the two longitudinal edges of the extendable load floor engage in these guide grooves as soon as the load floor is pulled beyond the loading edge. This guide groove then acts as a support element for the extended load floor in the vehicle's vertical direction. The guide grooves are L-shaped, and the longitudinal edges of the load floor are correspondingly L-shaped.

[0003] EP 3 061 636 A1 also describes a pickup truck with a rear loading floor, which, however, is not extendable. The two tailgates of the open loading area, each pivoting around an axis directed upwards towards the vehicle, have rectangular loading floor extensions on the inside, which are located in the 90 0-In the open state, the two tailgates can be folded from a vertical position to a horizontal position by means of a hinge, so that the two load floor extenders together form a flat surface that extends the rear load floor in a rearward direction.

[0004] From DE 102 03 539 B4 a vehicle is known with a loading flap pivotably mounted about a vertical axis for demarcating a cargo space with an extendable loading floor, wherein the movement of the loading flap is coupled with the movement of the loading floor.

[0005] A vehicle with a loading floor that can be moved beyond its loading edge is known from DE 103 12 466 B4. The loading floor is mounted so as to be movable by means of a guide arrangement. The guide channel includes a lifting device for adjusting the height of the loading floor, so that the loading floor can be adjusted between a lowered position and a raised position.

[0006] DE 102 10 884 B4 describes a roller shutter floor for the cargo area of ​​a vehicle. Telescopic rails are provided for the storage of the roller shutter floor, by means of which the floor can be rolled out in the cargo area of ​​the vehicle and, together with a movable section of the telescopic rails, can be moved beyond a loading edge of the vehicle.

[0007] A vehicle with a loading floor that can be extended beyond its loading edge is also known from DE 10 2006 009 886 A1. The loading floor is mounted in guide rails fixed to the vehicle and extending parallel to its longitudinal direction, allowing it to be moved and adjusted. When the loading floor is fully extended, legs located on its underside can be unfolded to support the loading floor against the ground. This allows the loading floor to also be used as a camping table. However, using the loading floor as a camping table can lead to reduced comfort if its unfolded legs have to rest on uneven ground.

[0008] The vehicle according to DE 103 48 493 A1 has a tailgate that pivots around a pivot axis oriented in the vehicle's vertical direction. On its inner side, at the bottom, this tailgate is connected to a circular storage compartment, so that when the tailgate pivots, the storage compartment is moved in or out of the trunk with a rotational movement. When the tailgate is open, this storage compartment can be used as a table or a seat. Furthermore, items can be placed on the storage compartment when the tailgate is open; these items remain on the compartment when the tailgate is closed and are pivoted into the interior of the trunk along with the tailgate.

[0009] The object of the invention is to provide a vehicle which is equipped with an extendable loading floor and with at least one loading compartment flap which closes a rear loading area and is pivotable about a pivot axis, so that improved and more comfortable use of the loading floor can be achieved.

[0010] This problem is solved by a vehicle with the features of claim 1.

[0011] Such a vehicle with - at least one cargo compartment door closing a rear cargo area, which can be pivoted about a pivot axis, - a loading floor located in the rear loading floor and movable in the longitudinal direction of the vehicle, which can be extended from a basic position in the rear direction over the loading opening of the rear loading area into a usable position, and - a support device which is arranged on the inside of the cargo hatch in such a way that at an opening angle of 900 The support device of the tailgate can be detachably connected to the loading floor by means of a positive locking connection in such a way that a force acting against the upward direction of the vehicle on the extended loading floor is absorbed by the tailgate. The invention is characterized by the fact that - the pivot axis of at least one cargo door is inclined relative to the vehicle's vertical direction, - the support device is rotatably or translationally pivotable or slidable relative to the cargo compartment flap between a storage position and a support position, and - the support device can be detachably connected in the support position with the positive locking connection (6).

[0012] According to the invention, the fully extended loading floor is supported by means of the support device which is pivoted or shifted into the support position, despite the inclination of the 90° 0The open tailgate is supported vertically, i.e., in the vehicle's upward direction, in such a way as to provide sufficient stability to bear a heavy load on the loading floor. Due to the inclination of the tailgate's axis of rotation relative to the vehicle's upward direction (z-direction), opening the tailgate results in an upward rotational movement in the vehicle's upward direction, thus creating an elevated working position. The support device according to the invention bridges the height difference between the extended loading floor and the lower edge of the tailgate in its supported position.

[0013] Thus, the load compartment floor, supported by the support device, can serve as a seat when extended. The extended load compartment floor can also be used comfortably as a table, as table legs are not required. Furthermore, in such a vehicle according to the invention, the trunk can be loaded in a more ergonomically favorable position using the extendable load compartment floor.

[0014] The pivot axis of at least one cargo compartment door is inclined relative to the vehicle's vertical direction in the longitudinal direction and / or in the transverse direction. In the transverse direction, the pivot axis is inclined either inwards or outwards relative to the vehicle.

[0015] A preferred further development of the invention provides that - the support device comprises a support plate on which the loading floor, extended into the usable position, rests with a support section of the edge area of ​​the loading floor running in the longitudinal direction of the vehicle, and - the positive locking connection comprises positive locking elements arranged on the support plate and the support section.

[0016] This represents a mechanically simple design that is cost-effective to implement and also ensures ease of use. It is advisable to position the support plate parallel to the plane of the loading floor in the support position.

[0017] The support device can be implemented in different ways.

[0018] According to a preferred embodiment, the support device comprises a pivot arm which is connected at one end to the support plate in an L-shape and at the other end pivotally connected to the cargo area flap. This represents a structurally simple solution.

[0019] An alternative embodiment provides that the support device has a support beam connected to the support plate in an L-shape, which is pivotally connected to the cargo door by means of a four-joint mechanism.

[0020] Finally, according to a further preferred embodiment of the invention, the support device has a support connected to the support plate in an L-shape, which is translationally connected to the cargo compartment door by means of a linear guide device.

[0021] Furthermore, with regard to the positive locking element, it is provided that a positive locking bolt, as a positive locking element, interacts with a complementary positive locking opening, as a further positive locking element, to form the positive locking connection. The complementary positive locking opening is designed as a cylindrical bore adapted to the positive locking bolt.

[0022] In another embodiment, the complementary positive locking opening is designed as a long groove open on one side, into which the positive locking bolt can be inserted. It is particularly advantageous if the long groove designed as a complementary positive locking opening is formed with an L-shape such that the positive locking bolt can be inserted through the long section of the L-shape and transferred to the short section of the L-shape.

[0023] To improve the insertion of the positive locking bolt into the elongated groove, this groove is designed to narrow conically starting from the open end face.

[0024] According to a further preferred embodiment of the invention, the elongated groove designed as a complementary form-locking opening is formed on the closed end face with a locking recess into which the form-locking bolt engages in the usable position of the extended loading floor.

[0025] According to a further preferred embodiment of the invention, the cargo compartment flap has an opening angle of 90°. 0 a lockable detent position. This prevents at least one cargo flap from being unintentionally swung open beyond the 90° position when the extended load floor is used, particularly as a seat, and thus the positive locking connection between the load floor and the cargo flap from being unintentionally released.

[0026] Furthermore, according to a further development of the invention, the support device is designed with a locking element that prevents the positive locking connection between the tailgate and the loading floor from unintentionally loosening. This prevents the positive locking connection from unintentionally loosening when the extended loading floor is in use, particularly when used as a seat.

[0027] Furthermore, it is advantageous if the vehicle is designed with two tailgates closing the rear cargo area. Of course, it is also possible for the vehicle to have only a single tailgate that extends across the entire width of the vehicle in the transverse direction.

[0028] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings. These show: Fig. 1 A schematic and perspective representation of the rear of a vehicle with cargo compartment doors and a loading floor extended from a rear cargo area and supported by a support device, Fig. 2a - 2c a schematic representation of different designs of a support device, Fig. 3 a schematic representation of a cargo compartment door with various designs of a support plate of a support device for an extended cargo floor, and Fig. 4 schematic sectional views of the in Fig. 3 support plates and associated positive locking elements shown in different designs.

[0029] Vehicle 1 according to Fig. 1 has a rear cargo compartment 2 with a rear cargo floor 2.1 and with two cargo compartment flaps 3.1 and 3.2, each of which is inclined about a pivot axis A in the vehicle longitudinal direction (x-direction) relative to the vehicle's vertical direction (z-direction), i.e. in the direction of travel F, between a position closing the rear cargo compartment 2 and an open position in which the two cargo compartment flaps 3.1 and 3.2 are opened by almost 180° 0 They are open to the outside and can be pivoted. Relative to a rotation axis A0 directed vertically in the vehicle's vertical direction, the rotation axes A are inclined by an angle α in the direction of travel F in the plane spanned by the vehicle's longitudinal and vertical directions.

[0030] In vehicle 1, the pivot axes A of the cargo compartment doors 3.1 and 3.2 can be inclined not only in the longitudinal direction (x-direction) of the vehicle, but also in the transverse direction (y-direction), or both in the longitudinal direction (x-direction) and in the transverse direction (y-direction) relative to the vehicle's vertical direction (z-direction). The pivot axis A can be inclined in the transverse direction either inwards relative to vehicle 1, so that the pivot axes A of the two cargo compartment doors 3.1 and 3.3 are inclined towards each other, or outwards relative to the vehicle.

[0031] Furthermore, the vehicle 1 has an extendable loading floor 4, which can be moved in the longitudinal direction of the vehicle (x-direction) between a basic position I (in Fig. 1 shown in dashed lines) and one can be moved backwards into a usable position II via a loading opening 2.2 of the rear loading compartment 2 (see arrow P).

[0032] In order for the loading floor 4 to absorb forces in its extended usable position II that are directed downwards in the vehicle's vertical direction (z-direction), the vehicle floor 4 is supported at its end in the area of ​​a support section 4.1 (see figure). Fig. 3) supported downwards by a support plate 5.1 of a support device 5 forming a positive locking connection 6, wherein the positive locking connection 6 is realized between the support plate 5.1 and the support section 4.1 of the vehicle floor 4.

[0033] This support device 5 is arranged on the inside of each of the two cargo compartment doors 3.1 and 3.2 and, in addition to the support plate 5.1, has an L-shaped pivot arm 5.2 connected to the support plate 5.1, which is pivotally connected with its free end to the inside of the cargo compartment door 3.1 or 3.2 by means of a swivel joint 5.0. With this pivot joint 5.0, the swivel arm 5.2 with the support plate 5.1 can be pivoted between a storage position III and a support position IV, whereby in support position IV, when the swivel arm 5.2 with the support plate 5.1 is pivoted downwards in the vehicle's vertical direction (z-direction), the loading floor 4 engages in its support section 4.1, i.e., the loading floor 4 can be placed onto the support plate 5.1 via its support section 4.1 in such a way that a force-fit connection to the cargo compartment door 3.1 and the cargo compartment door 3 is established via the swivel arm 5.2 and the pivot joint 5.0 respectively.2 is created, which have an opening angle of 90° and are therefore positioned in the longitudinal direction of the vehicle (x-direction).

[0034] The pivot joint 5.0 is positioned with its axis of rotation B on the inside of the cargo compartment door 3.1 or 3.2 such that the support section 4.1 of the loading floor 4 rests flat on the support plate 5.1. Thus, when the cargo compartment doors 3.1 and 3.2 are open at 90°, the axis of rotation B of the pivot joint 5.0 can, for example, be oriented in the longitudinal direction (x-direction) of the vehicle.

[0035] If the loading floor 4 is retracted into its basic position I, the support device 5 is pivoted upwards from the support position IV to a storage position III in the vehicle's vertical direction (z-direction) until the support plate 5.1 abuts the inside of the cargo compartment flap 3.1 or 3.2.

[0036] With this support device 5, the height difference in the vehicle's vertical direction (z-direction) between the lower edge of the cargo compartment door 3.1 or 3.2 and the support section 4.1 of the cargo compartment floor 4 is bridged, which, due to the axial inclination of the axis of rotation A, leads to a rotational movement of the cargo compartment door 3.1 or 3.2 upwards in the vehicle's vertical direction (z-direction).

[0037] The support device 5 can be implemented in different variants, whereby the Fig. 1, Fig. 2a and Fig. Figure 3 shows a simple folding variant of the support device 5, in which the swivel arm 5.2, which is connected in an L-shape to the support plate 5.1, is either pivoted from a storage position III adjacent to the inside of the cargo compartment flap 3.1 or 3.2 to a downward position in the vehicle's vertical direction into the support position IV, or vice versa, from the support position IV back to the storage position III.

[0038] Another variant of the support device 5 is in Fig. Figure 2b shows a support 3 with a support plate 5.1 arranged at one end, the support plate 5.1 being connected to the support 3 in an L-shape. The support 3 is pivotally connected to the inside of the cargo compartment door 3.1 and 3.2, respectively, via a four-bar linkage 5 with a hinged arm 5.40 and another hinged arm 5.41. With the two hinged arms 5.40 and 5.41 being of equal length, a parallelogram is formed, so that the support 3, together with the support plate 5.1, can be pivoted from the storage position III to the support position IV, whereby the support 5.3, which extends in the vehicle's vertical direction (z-direction), is only moved downwards in the vehicle's vertical direction to overcome a corresponding height difference z1.

[0039] A third variant of the support device 5 shows the Fig. 2c, comprising a support 3 with a support plate 5.1 arranged at its end, the support plate 5.1 being connected to the support 3 in an L-shape. The support 3 is connected to the inside of the cargo compartment door 3.1 or 3.2 via a linear guide 5.5, which is only shown schematically. This linear guide 5.5 moves the support 3 together with the support plate 5.1 downwards from position III (viewed in the vehicle's vertical direction) to support position IV. The linear guide 5.5 is, of course, oriented in the vehicle's vertical direction in this case. This linear guide 5.5 also overcomes a corresponding height difference z1.

[0040] As already indicated above, the support function of the support plate 5.1 is secured by means of a positive locking connection 6 to prevent unintentional loosening of the force-fit connection to the cargo compartment door 3.1 or 3.2. For this purpose, positive locking elements 6.1, 6.10, 6.2 and 6.20 are provided, with positive locking elements 6.1 and 6.10 being implemented on the cargo floor 4 and positive locking elements 6.3 and 6.20 on the support plate 5.1.

[0041] According to Fig. 3 is a support device 5 which is already in Fig. 1 and Fig. The variant described in 2a is shown. This support device 5 comprises the support plate 5.1, which is connected in an L-shape to the swivel arm 5.2, wherein the swivel arm 5.2 is arranged on the inside of the cargo compartment door 3.1 by means of a pivot joint 5.0 and can be pivoted between the storage position III and the support position IV by means of this pivot joint 5.0.

[0042] When the loading platform 4 is extended into its operating position II, a positive locking element 6.1, designed as a positive locking bolt 6.10 and arranged on the loading platform 4, is inserted into a complementary positive locking opening 6.20 of the support plate 5.1 as a further positive locking element 6.2. This complementary positive locking opening 6.20 of the support plate 5.1 is designed as an open-ended longitudinal groove, so that the positive locking bolt 6.10 can be inserted into this longitudinal groove via the open end face and moved to its end by means of the loading platform 4.

[0043] The positive locking bolt 6.10, designed as a positive locking element 6.1, is arranged in an edge region 4.0 of the loading floor 4 in the area of ​​the support section 4.1 such that it can be inserted into the elongated groove designed as a complementary positive locking opening 6.20. Thus, in the operating position II of the loading floor 4, the positive locking bolt 6.10 projects into this elongated groove, so that the loading floor 4 rests with its lower main surface on the support plate 5.1, and a vertically downward force acting on the loading floor 4 is absorbed via the support plate 5.1 and the pivot arm of the cargo compartment door 3.1 or 3.3.

[0044] The position of the support plate 5.1 arranged on the cargo compartment flap 3.1 via the pivot arm 5.2 and the position of the positive locking element 6.10 on the loading floor 4 are coordinated so that in the operating position II of the loading floor 4 the positive locking connection 6 between the positive locking bolt 6.10 and the elongated groove designed as a complementary positive locking opening 6.20 can be established.

[0045] Alternative versions of the support plate 5.1 are described in the Fig. 3 is designated with the reference symbols 5.1', ​​5.1'' and 5.1'''.

[0046] The support plate 5.1' is designed with a cylindrical bore as a complementary positive-lock opening 6.20', so that in the operating position II of the loading floor 4, the positive-locking bolt 6.10 can be inserted into this cylindrical bore. By slightly raising the loading floor 4 shortly before it reaches operating position II, the positive-locking bolt 6.10 is raised onto the support plate 5.1', ​​so that the positive-locking bolt 6.10 can engage in the cylindrical bore. This simultaneously locks the positive-locking connection 6, thus preventing unintentional loosening of the positive-locking connection 6 between the support plate 5.1' and the loading floor 4.

[0047] The two support plates 5.1'' and 5.1''' are each designed with an L-shaped elongated groove as a complementary positive locking opening 6.20" and 6.20''' respectively, wherein the long section L1 and L2 is designed as a elongated groove open on one side, which transitions into the short section K1 and K2 of the L-shaped elongated groove designed as a complementary positive locking opening 6.20" and 6.20''' respectively. As the loading floor 4 is extended, its positive locking bolt 6.10 engages in the long section L1 or L2 of the L-shaped groove, designed as a complementary positive locking opening 6.20" or 6.20''', shortly before reaching the operating position II, and is guided into the short section K1 or K2. The relative movement in the transverse direction of the vehicle between the positive locking bolt 6.10 and the support plate 5.1" or 5.1''' is enabled by an elastic movement of the loading compartment flap 3.1 or 3.2, so that the positive locking bolt 6.10 is guided into the short section K1 or K2.K2 engages, thereby achieving a locking of the positive locking connections 6 between the loading floor 4 and the two loading compartment flaps 3.1 and 3.2.

[0048] The difference between the two complementary positive locking openings 6.20'' and 6.20''' is that the long section L2 of the complementary positive locking opening 6.20''' tapers conically from the open end face towards the short section K2. This facilitates the insertion of the positive locking bolt 6.10 into such a complementary positive locking opening 6.20'''.

[0049] Different versions of the positive locking bolt 6.10, designed as a positive locking element 6.1, are described in Fig. 4 shown, where the Fig. 4a) and Fig. 4 b) represent an x-section in the area of ​​the longitudinal grooves of the support plates 5.1, 5.1'' and 5.1''', while Fig. 4c) the CC section according to Fig. 3 shows the y-intercept.

[0050] Thus, according to Fig. 4a) The positive locking bolt 6.10, designed as a positive locking element 6.1, is designed as a cylindrical pin. According to Fig. 4b) this cylindrical pin has a mushroom head, with the complementary form-closing opening 6.20, 6.20'' and 6.20''' located thereon according to Fig. 4b) is adapted.

[0051] To enable the positive locking bolt 6.10 to engage in the operating position II of the loading platform 4, the elongated groove, designed as a complementary positive locking opening 6.20, has a locking recess 6.21 at its closed end, into which the positive locking bolt 6.10 engages when the loading platform 4 is extended to its operating position II. Such a locking recess can also be additionally implemented in the complementary positive locking openings 6.20" and 6.20''' of the support plate 5.1" and 5.1''' in the area of ​​the short section K1 and K2.

[0052] The different versions of the support plate 5.1, 5.1', ​​5.1" and 5.1'' according to the Fig. 3 and Fig. 4 with different versions of the positive locking elements 6.1, 6.10, 6.2, 6.20, 6.20', 6.20" and 6.20''' are of course also available on the support device 5 according to the Fig. 2b and Fig. 2c applicable.

[0053] The two cargo compartment doors 3.1 and 3.2 can be fitted with a locking mechanism in their 90° position to prevent unintentional pivoting beyond the 90° opening.

[0054] The exemplary embodiment according to Fig. Figure 1 describes a vehicle 1 with two cargo hatches 3.1 and 3.2. It is also possible, of course, that the vehicle has only a single cargo hatch that covers the entire loading opening 2.2. In this case, a positive locking connection is only made on the side of the loading floor 4 adjacent to the single cargo hatch.

[0055] Such an extendable cargo floor 4 of a vehicle, which is supported in the vertical direction of the vehicle by at least one cargo door 3.1 or 3.2 by means of the support device 5, offers the user extended usage options. For example, this cargo floor 4 can be used as a seat or table in its operating position II. Furthermore, the rear cargo area 2 of the vehicle 1 can be loaded in a more ergonomically favorable position for the user when the cargo floor 4 is extended to operating position II. Finally, securing elements for securing cargo can be integrated into the cargo floor 4.
