Description

[0001] The invention relates to a loading floor for a loading space, in particular a luggage compartment, of a vehicle, in particular a motor vehicle.

[0002] The loading floor of a luggage compartment of a motor vehicle, particularly a passenger car, can be equipped with slide rails to allow cargo to be pushed into the luggage compartment over the slide rails with reduced effort. Alternatively, anti-slip rails can be arranged on the loading floor to prevent cargo placed on the loading floor or the anti-slip rails from slipping while the motor vehicle is in operation. However, anti-slip rails make it more difficult to place cargo into the luggage compartment, as the cargo can only be pushed over the anti-slip rails with considerable effort. Slide rails have the disadvantage that cargo placed on them can easily slip while the motor vehicle is in operation.

[0003] From DE 10 2005 007 431 A1 a loading space for vehicles with several sliding segments is known.

[0004] The object of the invention is to simplify the introduction of cargo into a loading space of a motor vehicle and at the same time to prevent cargo from slipping on a loading floor of the loading space as far as possible.

[0005] This object is achieved by the independent claim. Advantageous embodiments are particularly recited in the dependent claims, each of which, taken individually or in various combinations, may constitute an aspect of the invention.

[0006] The loading floor according to the invention for a loading space, in particular a luggage compartment, of a vehicle, in particular a motor vehicle, comprises: - at least one sliding unit with at least one loading-side sliding surface; - at least one anti-slip unit with at least one anti-slip surface on the loading side, - wherein the sliding unit and / or the anti-slip unit are arranged to be movable at least partially transversely or longitudinally to the loading floor in such a way that the sliding unit, in a first relative position between the sliding unit and the anti-slip unit, at least partially projects beyond the anti-slip unit on the loading side, and that the anti-slip unit, in a second relative position between the sliding unit and the anti-slip unit, is arranged at least partially at the same level as the sliding unit or projects beyond the sliding unit on the loading side; and - at least one drive device which can be operatively connected to the sliding unit and / or the anti-slip unit for moving the sliding unit and / or the anti-slip unit. Furthermore, the loading floor has at least one sliding rail which can be arranged in the longitudinal direction of the vehicle and which is connected to the anti-slip unit at the front or rear. If the loading space is located, for example, at the rear of the motor vehicle, the anti-slip unit is preferably connected to the sliding rail at the rear. If the loading space is located, for example, at the front of the motor vehicle, the anti-slip unit is preferably connected to the sliding rail at the front. If the loading space is located, for example, on the side of the vehicle, the anti-slip unit can preferably be arranged closer to the respective side of the vehicle than the sliding rail.

[0007] Within the scope of the invention, the term "loading side" refers either to a movement toward the loading space located above the loading floor or to a section of a component located closest to the loading space. Within the scope of the invention, the term "off-loading side" refers either to a movement away from the loading space located above the loading floor or to a section of a component located furthest from the loading space.

[0008] If the sliding unit and the anti-slip unit are in their first relative position, a load can be easily introduced into the loading space because the load only comes into contact with the higher sliding surface of the sliding unit, over which the load can be pushed into the loading space with little effort until it reaches a desired position. In other words, the anti-slip unit is recessed when the sliding unit and the anti-slip unit are in their second relative position. Once the load has assumed this desired position, the sliding unit and the anti-slip unit can be moved into their second relative position by means of the drive device, so that a load placed on the loading floor comes into contact with the anti-slip surface of the anti-slip unit, which is at the same level or higher.This largely prevents the load from slipping on the loading floor while the vehicle is in motion. The loading floor according to the invention thus combines the advantages of conventional slide rails and anti-slip rails. If the anti-slip unit is at least partially at the same level as the slide unit, the load placed on the anti-slip unit and the slide rail can be secured against slipping by surface pressure between the load and the anti-slip unit.

[0009] In order to move the sliding unit and the anti-slip unit back and forth between their first relative position and their second relative position, the drive device can be used to move either the sliding unit alone or the anti-slip unit, or both the sliding unit and the anti-slip unit can be moved.

[0010] The loading-side sliding surface of the sliding unit can extend over part or all of the loading-side upper surface of the sliding unit. Alternatively, the sliding unit can have several spaced-apart loading-side sliding surfaces. The loading-side sliding surface can have a friction-reducing surface design to impart the desired sliding friction properties to the sliding unit. Alternatively or additionally, the sliding unit can be partially or completely made of a material that has the desired sliding friction properties.

[0011] The loading-side anti-slip surface of the anti-slip unit can extend over part or all of the loading-side upper side of the anti-slip unit. Alternatively, the anti-slip unit can have a plurality of spaced-apart loading-side anti-slip surfaces. The loading-side anti-slip surface can have a friction-increasing surface design to impart the desired static friction properties to the anti-slip unit. Alternatively or additionally, the anti-slip unit can be made partially or entirely from a material that has the desired static friction properties. The anti-slip unit can be formed at least partially from an elastomer, in particular a rubber. Elastomers have sufficient anti-slip properties for the purpose of the invention. The anti-slip unit can be formed at least on its loading-side upper side or else entirely from an elastomer.For example, the anti-slip unit may have at least one rubber profile.

[0012] The sliding unit and / or the anti-slip unit can be arranged so as to be movable, in particular, perpendicular to the loading floor. The sliding unit and / or the anti-slip unit can be arranged on the base unit so as to be movable exclusively transversely to the loading floor. Suitable guide means can be arranged on the sliding unit or the anti-slip unit for this purpose. The anti-slip unit can be arranged laterally next to the sliding unit. Alternatively, the anti-slip unit can be arranged completely within the sliding unit when the first relative position between the sliding unit and the anti-slip unit is present, and partially or not at all within the sliding unit when the second relative position between the sliding unit and the anti-slip unit is present. The latter configuration saves installation space than arranging the anti-slip unit laterally on the sliding unit.

[0013] To move the sliding unit and / or the anti-slip unit, the drive device can be supported on one side by the sliding unit and on the other side by the anti-slip unit. Alternatively or additionally, the drive device can be supported on one side by the vehicle. To move the sliding unit and / or the anti-slip unit, the drive device can be operatively connected to the sliding unit or the anti-slip unit, for example, via suitable coupling means. The drive force of the drive device can be transmitted to the sliding unit or the anti-slip unit directly or indirectly, for example via mechanical means.

[0014] The loading floor according to the invention can also comprise two or more corresponding sliding units, anti-slip units, and drive devices arranged distributed across the loading floor. A common drive device can also be provided for moving two or more sliding units and / or anti-slip units. The sliding units and the anti-slip units can be aligned parallel or transversely to the vehicle's longitudinal extension. Furthermore, the sliding units and the anti-slip units can be arranged distributed across the loading floor in the form of a regular grid or pattern.

[0015] The drive device can be controlled automatically or manually. Automatic control of the drive device can occur, for example, depending on a detected operating state of the vehicle. If the vehicle is parked, for example, the drive device can be automatically controlled such that the drive device moves the sliding unit and the anti-slip unit into their first relative position and holds them there. If, however, a vehicle start or a driving state of the vehicle is detected, the drive device can be automatically controlled such that the drive device moves the sliding unit and the anti-slip unit into their second relative position and holds them there.Alternatively, the drive device can be automatically controlled depending on a detected state of a vehicle's tailgate. The drive device can move and hold the sliding unit and the anti-slip unit in their first relative position during or after the tailgate is opened, whereas the drive device can move and hold the sliding unit and the anti-slip unit in their second relative position during or after the tailgate is closed. Alternatively, the drive device can also be automatically controlled depending on a detected load state of the vehicle.For example, the drive device can be automatically controlled such that, upon detection of a predefined load level of the vehicle, the sliding unit and the anti-slip unit are moved into their second relative position and held therein. However, upon detection of the predefined load level, the sliding unit and the anti-slip unit are moved into their first relative position and held therein. With manual control of the drive device, a person can, if necessary, trigger an electrical or mechanical control of the drive device, for example, by pressing an actuating means, in particular a control button or a control panel.

[0016] According to an advantageous embodiment, the sliding unit comprises at least one base unit which can be fastened to the vehicle, the loading floor or another vehicle component and on which the anti-slip unit is arranged so as to be movable at least partially transverse to the loading floor, wherein the drive device has at least one displacement body arranged so as to be movable on the base unit and at least one sliding or rolling body which can be connected to an underside of the anti-slip unit which is remote from the loading area and can be guided on the displacement body, and wherein the displacement body is arranged so as to be movable on the base unit between an active position in which the sliding unit and the anti-slip unit are held in their second relative position via the displacement body and the sliding or rolling body, and a passive position in which the sliding unit and the anti-slip unit are not moved from their first relative position via the displacement body and the sliding or rolling body.By moving the displacement body between its active position and its passive position, the sliding unit and the anti-slip unit can be moved from their first relative position to their second relative position, and vice versa. To this end, the displacement body interacts with the sliding or rolling body in such a way that when the displacement body moves from its passive position to its active position, the sliding or rolling body is displaced on the loading side, thereby moving the sliding unit and the anti-slip unit into their second relative position. If the displacement body is moved from its active position to its passive position, the sliding unit and the anti-slip unit can move automatically from their second relative position to their first relative position by means of the weight force acting on them.Alternatively, a mechanical return means, in particular a mechanical spring, can be used, which acts, for example, on the one hand on the sliding unit and on the other hand on the anti-slip unit. Physically, the reverse process is of course also conceivable, in which the anti-slip unit and the sliding unit are moved by means of the spring from their first relative position to their second relative position and by means of the displacement body from their second relative position to their first relative position. The displacement body can be designed as a guide ramp with a wedge-shaped section and an adjoining portal section, wherein the portal section interacts with the sliding or rolling body when the displacement body is in its active position in order to be able to hold the sliding unit and the anti-slip unit in their second relative position without the application of force.The displacement body and / or the sliding or rolling body can be made of metal or a composite material. The drive device can also have two or more displacement bodies and a corresponding number of sliding or rolling bodies. The displacement body can alternatively be designed as a guide lug or the like. The base unit can be attached to the loading floor, a panel, the vehicle, or the like using suitable fastening means, for example screw connections, rivet connections, adhesive connections, or the like. The base unit can be made partially or entirely of metal, in particular aluminum.

[0017] Advantageously, the displacement body and the sliding body are designed as ramps arranged in opposite directions. This represents a structurally simple design of the drive device.

[0018] It is further advantageous if the drive device has at least one drive that can be operatively connected to the displacement body for moving the displacement body movably arranged on the base unit. The drive can be manually operable or electrically, pneumatically, or hydraulically controllable. The drive can be connected to the base unit on the one hand and to the displacement body on the other hand via suitable mechanical coupling means. The drive can also be configured to jointly drive two or more anti-slip units of the loading floor. The drive can be arranged inside or outside the base unit. The drive device can also have two or more corresponding drives.

[0019] According to a further advantageous embodiment, the drive comprises at least one manually operable lever that is operatively connected to the displacement body movably arranged on the base unit, and by actuating said lever, the displacement body can be moved. This creates a manually operable drive. The lever can be designed, in particular, as a two-armed lever, the load arm of which can be connected to the displacement body. The drive can also comprise two or more corresponding levers.

[0020] According to a further advantageous development, the drive comprises at least one electrically controllable electric motor that is operatively connected to the displacement body movably arranged on the base unit, and by means of which the displacement body can be moved. This allows the movement of the anti-slip unit to be automated. The drive can also comprise two or more corresponding electric motors. Alternatively, the drive can comprise at least one artificial muscle or a shape-memory material.

[0021] A further advantageous embodiment provides that the drive has at least one wire made of a shape memory alloy that can be operatively connected to the displacement body movably arranged on the base unit and to the base unit, and a return unit that can be connected to the displacement body and the base unit. The displacement body can be moved from its passive position to its active position by energizing the wire and from its active position to its passive position by means of the return unit. When energized, the wire contracts and thereby moves the displacement body from its passive position to its active position. The return unit can be used to apply force to the displacement body in the direction of its passive position. The drive can also have two or more corresponding wires and / or return units.

[0022] Advantageously, the return unit comprises at least one mechanical tension spring or an energizable wire made of a shape memory alloy. When energized, the wire of the return unit contracts, thereby moving the displacement body from its active position to its passive position. The return unit can also comprise two or more corresponding mechanical springs or wires.

[0023] According to a further advantageous development, the sliding unit comprises at least one base unit which can be fastened to the vehicle, the loading floor or another vehicle component and on which the anti-slip unit is arranged so as to be movable at least partially transversely to the loading floor, wherein the drive device has at least one flexibly designed expansion unit which can be arranged on the underside of the anti-slip unit within the base unit, away from the loading, and which can be supplied with a pressurized fluid. When acted upon by the pressurized fluid, this expansion unit expands at least transversely to the loading floor and thereby displaces the anti-slip unit on the loading side. By expanding the expansion unit when supplied with the pressurized fluid, the anti-slip unit is displaced on the loading side, whereby the sliding unit and the anti-slip unit are transferred into their second relative position.After the expansion unit is no longer supplied with pressurized fluid, the expansion unit shrinks again due to its flexible, particularly elastic, properties, so that the anti-slip unit can move back toward its retracted rest position by means of the weight acting on it or using suitable return means, whereby the sliding unit and the anti-slip unit are transferred to their first relative position. The expansion unit can be balloon-like and can be supplied with a gaseous or liquid pressurized fluid, particularly compressed air or hydraulic fluid. For this purpose, the expansion unit can be connected to a controllable fluid supply unit, particularly an air pump or a hydraulic pump, of the motor vehicle. The drive device can also have two or more corresponding expansion units.

[0024] According to a further advantageous embodiment, the sliding unit has at least one base unit which can be fastened to the vehicle, the loading floor or another vehicle component and on which the anti-slip unit is arranged so as to be movable at least partially transversely to the loading floor, wherein the anti-slip unit has at least one elastomer body and the drive device has at least one drive body which can be arranged within the base unit, and wherein the drive body is arranged so as to be movable on the base unit between an active position in which the drive body partially displaces the elastomer body on the loading side so that the sliding unit and the anti-slip unit are held in their second relative position, and a passive position in which the drive body does not displace the elastomer body so that the sliding unit and the anti-slip unit are not moved from their first relative position.This represents an alternative and structurally simple design of the loading floor. The drive device can also have two or more drive bodies, for example made of metal or plastic.

[0025] According to a further advantageous embodiment, the loading floor comprises at least one base unit which can be fastened to the vehicle, the loading floor or another vehicle component and on which the anti-slip unit is arranged so as to be movable at least partially transversely to the loading floor, wherein the anti-slip unit has at least one flexible elastomer body and the sliding unit has at least one sliding body which is smaller than the elastomer body, wherein the base unit is closed with the elastomer body on the loading side to form a pressure chamber, wherein the sliding body is fixed to the elastomer body on the loading side and in the middle, and wherein the elastomer body sags on the loading side without pressure being applied to the pressure chamber in such a way that edge-side connecting sections of the elastomer body, via which the elastomer body is connected to the base unit, project at least partially beyond the sliding body on the loading side.Without pressurizing the pressure chamber, the elastomer body sags on the loading side due to its own weight and the added weight of the sliding body. This also represents an alternative and structurally simple design for the loading floor.

[0026] A further advantageous embodiment provides that the loading floor comprises at least one base unit which can be fastened to the vehicle, the loading floor or another vehicle component and on which the anti-slip unit is arranged so as to be movable at least partially transversely to the loading floor, wherein the anti-slip unit has at least one flexible elastomer body with which the base unit is closed on the loading side to form a pressure chamber, wherein the sliding unit is formed by at least one loading floor element, wherein the sliding unit at least partially projects beyond the elastomer body on the loading side without pressurization of the pressure chamber, and wherein the elastomer body bulges on the loading side when pressurization of the pressure chamber occurs such that a central section of the elastomer body at least partially projects beyond the sliding unit on the loading side or is arranged at the same level as the sliding unit.The loading floor element forming the sliding unit can be a conventional loading floor element. Without pressurizing the pressure chamber, the elastomer body can, for example, be arranged on the base unit in such a way that it extends essentially in one plane.

[0027] According to a further advantageous embodiment, the anti-slip unit is formed by at least one loading floor element, wherein the sliding unit has at least one sliding body which can be arranged on the vehicle by means of the drive device so as to be movable back and forth between a sliding position in which the sliding body at least partially projects beyond the anti-slip unit on the loading side, and a rest position in which the anti-slip unit at least partially projects beyond the sliding body on the loading side or is arranged at the same level as the sliding body. The loading floor element forming the anti-slip unit can be formed by a conventional loading floor element that has sufficient static friction properties. The sliding body can be arranged so as to be movable on its own, while the anti-slip unit is arranged immobile.

[0028] According to a further advantageous embodiment, the loading floor comprises at least one base unit which can be fastened to the vehicle, the loading floor or another vehicle component and on which the anti-slip unit is arranged in a form-fitting manner, at least partially movable transversely to the loading floor. The anti-slip unit has at least one flexible elastomer body in which a pressure chamber is arranged. The sliding unit is formed by at least one loading floor element. The sliding unit at least partially projects beyond the elastomer body on the loading side without pressurization of the pressure chamber. A loading-side section of the elastomer body bulges on the loading side when pressurization of the pressure chamber occurs such that the loading-side section of the elastomer body at least partially projects beyond the sliding unit on the loading side or is arranged at the same level as the sliding unit. This represents a relatively space-saving design of the loading floor.The loading floor element forming the sliding unit may be formed by a conventional loading floor element.

[0029] A further advantageous embodiment provides that the sliding unit has at least one base unit attachable to the vehicle, the loading floor, or another vehicle component, on which base unit the anti-slip unit is arranged so as to be movable at least partially transversely to the loading floor. The drive device has at least one eccentric that can be arranged on the underside of the anti-slip unit within the base unit, away from the loading area, and is arranged on a drive shaft arranged parallel to the loading floor, the control path of which eccentric interacting directly or indirectly with the underside of the anti-slip unit. This electromechanical embodiment of the drive device is structurally simple and relatively robust. The drive shaft can be driven electrically or mechanically.

[0030] According to a further advantageous embodiment, the sliding unit and / or the anti-slip unit are / is designed in a rail-shaped manner. This allows for a relatively large contact area between the sliding unit or the anti-slip unit and a load to be arranged or placed thereon, which is accompanied by an optimization of the properties of the loading floor described above. The rail-shaped sliding unit or anti-slip unit can, for example, be arranged extending parallel to the longitudinal direction of the vehicle. Alternatively, the sliding unit and the anti-slip unit can be designed in a point-like manner or in another way.

[0032] In the figures, functionally identical components are provided with the same reference numerals.

[0033] Fig. 1 shows a schematic front view of an embodiment of a loading floor 1 according to the invention for a loading floor (not shown) of a luggage compartment of a motor vehicle.

[0034] The loading floor 1 comprises a sliding unit 2 with a sliding surface 3 on the loading side. Surface structures 4 in the form of local elevations are formed on the sliding surface 3 to reduce friction.

Alternatively, the anti-slip unit 5 can also be arranged so as to be movable longitudinally to the loading floor 1. As a result, the anti-slip unit 5 is arranged so as to be movable at least partially transversely to the loading floor 1, such that the sliding unit 2 can be moved in a Fig. 1 shown first relative position between the sliding unit 2 and the anti-slip unit 5 on the loading side at least partially projects beyond the anti-slip unit 5 and that the anti-slip unit 5 in a Fig. 2 shown second relative position between the sliding unit 2 and the anti-slip unit 5 on the loading side at least partially projects beyond the sliding unit 2 or is arranged at the same level as the sliding unit 2.

The drive device 9 further comprises a drive (not shown) which can be operatively connected to the displacement body 10 for moving the displacement body 10 arranged on the base unit 7.

[0037] Fig. 2 shows a schematic front view of the Fig. 1 shown loading floor 1 in the presence of the second relative position between sliding unit 2 and anti-slip unit 5. For this purpose, the displacement body 10 is moved from its Fig. 1 shown passive position across the plane of the drawing into its Fig. 2. In the second relative position, the anti-slip unit partially projects beyond the sliding unit 2 on the loading side or is arranged at the same level as the sliding unit 2.

[0038] Fig. 3 shows a schematic side view of a further embodiment of a loading floor 1 according to the invention in the presence of the first relative position between the sliding unit 2 and the anti-slip unit 5. The loading floor 1 can be arranged in accordance with the Fig. 1 and Fig. 2. The drive device 9 of the loading floor 1 comprises a plurality of displacement bodies 10 arranged in series with one another, movable via the plate 13 on the base unit (not shown in detail), and a plurality of sliding bodies 12 in the form of ramps arranged in series with one another, connected to the underside 11 of the anti-slip unit 5 facing away from the loading area via the plate 14, and guided on the displacement bodies 10. The displacement bodies 10 are arranged between a Fig. 4, in which the sliding unit 2 and the anti-slip unit 5 are held in their second relative position via the displacement bodies 10 and the sliding bodies 12, and in Fig. 3, in which the sliding unit 2 and the anti-slip unit 5 are not moved from their first relative position via the displacement bodies 10 and the sliding bodies 12, they are movably arranged on the base unit.
