Abstract

The device (1) has a loading base (3) with a loading surface (5) for accommodation of loaded goods (11). A fixing system (9) exhibits an elastic material in an area of a discharge opening (7) of the loading base. The fixing system is guided from a loading position into a fixing position. The fixing system is guided into the fixing position by forming a hollow protuberance and subjecting the areas with the elastic material with fluid pressure. A section of the protuberance is passed from the discharge opening over a level of the loading surface into the fixing position.

Description

The The present invention relates to a security device for Load according to the preamble of claim 1 or the preamble of claim 5. It further relates to a motor vehicle according to the preamble of claim 10.

From the DE 37 38 762 A1 is an anti-slip device for a storage area known. This has a support plate for receiving cargo with a smooth surface and through openings. Through the passages solid knobs of adhesive material can be pushed through such that they come into contact with the load in a fixing position and fix the load against slipping on the otherwise smooth surface. For loading and unloading of the load on or from the support plate, the knobs are pulled back below a level of the smooth surface and into the passage openings. The load can be moved easily in this loading position of the knobs on the support plate. In this case, the knobs can be moved relative to the fixed support plate along the passage openings, or conversely, the support plate can be moved relative to the fixed knobs. In both cases, the movement is effected by means of compressed air.

The anti-slip device of the DE 37 38 762 A1 however, has several disadvantages. One of these disadvantages is that the nubs are performed comparatively inaccurate and can jam or hang on the transition from the loading position in the fixing position on or in the passage openings. A further disadvantage is that dirt, which reaches the passage openings in the loading position, narrows them and makes it more difficult or prevents later passage of the knobs.

task It is therefore an improved securing device of the present invention to propose for cargo.

These The object is solved by the features of claim 1. Advantageous embodiments of the invention are the subject the dependent claims.

According to the invention proposed a securing device, which is a one-piece or multipart loading floor with at least one loading surface having. The loading floor has one or more outlet openings on. The securing device also has at least one fixing system which consists of at least one loading position in at least one Fixation position is transferable,

To An embodiment of the present invention comprises the fixing system at least in the region of the outlet opening an elastic Material on. This fixing system is designed such that a section of this when applying pressure to the area with the elastic material evades. The resulting Protrusion rises so that at least one section the protuberance from the outlet opening over the level of the loading surface protrudes. This position corresponds to the fixing position, the invention is not limited to a Position is limited as a fixation, but everyone Condition in which at least a portion of the protuberance over the level of the loading surface reaches and on the loading surface parked cargo - as described in more detail below will - can fix, as a fixation position in the sense the invention is to be understood.

Under Fixing is in particular a positive and / or frictional Obstructing slippage of the on the loading surface parked goods understood, whereby by the invention both a complete prevention of slippage as well a restriction of slippage is included. The slipping of the Load on the loading surface is thereby through the obstacle, fence, wall, wall-like or the like from the outlet opening out-extending protuberance or restricted, at the side edge of which a slipping movement of the load ends, or which a slipping motion of the load does not even arise leaves.

Under an elastic material is understood in particular as a material which under pressure a protuberance such, in particular bulge-like with at least partially hollow profile, can form, that the protuberance by absorption of laterally acting Forces due to slipping load one as above described fixing effect on the slipping load (for example in the luggage or luggage compartment of a motor vehicle parked luggage) can exercise. The elastic material allows the Protuberance in the absence of pressurization on the Material in its initial position - d. H. in the position before applying the pressure - goes back. The elastic Material thus allows a repeated and reversible protuberance in the designated area.

In a loading position, the fixation system - unlike in the fixation position - no protuberance on, which goes beyond the level of the loading surface and slipping of the load on the loading surface with special needs. The load can therefore in the loading position without impairment be moved by the fixing system on the loading surface. It is obvious that the fixing system also in the loading position may have a protuberance. Such, possibly existing However, protuberance is not sufficient in the loading state the level of the loading surface that they are there parked load effectively against slipping as above would secure defined. Thus, the fixation system according to the invention in The loading position not only one, always take the same position. The actual position of the fixation system may be in the Rather varied loading. Each position in which the protuberance in the loading position slipping of the cargo on the loading surface essentially allows, therefore, a loading position define within the meaning of the present invention.

The Protrusion may be everted in their Form have any suitable shape. The possible forms include u. a. elongated, narrow strips, cones, hemispheres, Pins, rails, strips and the like, without being limited thereto to be. The protuberance can be present individually. The fixation system however, may also be a plurality or plurality of protuberances exhibit. The protuberances can, if there are several are all the same shape or at least two different shapes exhibit.

Under an outlet opening is in particular a depression understood, which is provided in the region of the loading floor such that the protuberance in the loading position - if the protuberance is formed in the loading position - or the protuberance enabling elastic material is arranged below a level of the loading floor surface, to prevent slippage of the load on the loading surface not to hinder. In this case, the outlet opening as Blind hole in the loading floor, as a passage opening through the Loading floor through, as a gap between different cargo floor sections or the like may be provided.

The Safety device allowed by applying pressure on the elastic region of the fixation system advantageously a fixation, if such, for example, while driving with a Car with safety device according to the invention, in the hold, for example, suitcases, which also when cornering or the like should not slip, is desired. Likewise, the load can be in the loading of the Fixing system without obstruction by this easily on the loading surface move, for example, to load and unload the suitcase may be desired.

The Fixing system of the securing device is in a preferred Embodiment both in the load position as well in the fixing position with a peripheral edge of the outlet opening connected or is attached to this.

These Design allows a material-saving provision of the fixing only in the area of the outlet openings; in the area between Outlets may be the fixation system and thus material be saved on the other hand.

Further prevents the connection of the fixing system with the edge of the outlet opening, that dirt through the outlet opening into a lower Enter the area of the loading floor and there - in all Usually difficult to remove - can accumulate.

In a further preferred embodiment of the invention Securing device, the fixing system is substantially flat or sheet-shaped and essentially arranged below the loading surface and advantageously connected to this. This embodiment leaves to be particularly space-saving and occupies little of the for example, in a car existing cargo space. It is suitable therefore particularly good as a retrofit device, for example for cars, which are not already factory with one Securing device have been equipped.

In a turn further preferred embodiment of the invention Securing device, this has a means for applying of fluid pressure, in particular a compressor, on. By means of this Setting up the elastic area can be easy and inexpensive Be eviscerated way. It is different than conventional, mechanical solutions for applying pressure are not required a special constructive accuracy in the design of the Safety device and in particular to comply with the fixing system, Since the fluid pressure advantageously taking advantage of the fluid or flowing properties of the pressure used to apply Fluids even without precise kinematics or specifically designed Transfers ways to transmit the pressure to a destination can be.

The Providing a device for applying fluid pressure brings another advantage with it: the one for generating the protuberance applied fluid pressure is locally variable. It requires no device and in particular no kinematically complex Set up to make sure you have multiple orifices at least a first area everted with elastic material Can not be if a second area with elastic material is not can be eviscerated because z. B. a heavier load is stored on an outlet opening and an everting of the concealed by the load second area with elastic Material prevented by the applied pressure. In other words are separated from each other ausstülpbare areas for fixation recruiting without this being made possible by a special device would have to be.

In In this embodiment, the elastic material may preferably be provided substantially fluid-tight, adapted to the used Fluid. The fluid used, for which the device suitable for applying fluid pressure, a gas, a liquid or any other flowing medium. Especially preferred This is air, not least because of their simple and inexpensive Availability and non-toxicity. In addition, motor vehicles today regularly compressors, which at Use of the securing device according to the invention in a motor vehicle can thus have another function. The cost of providing the device for application of fluid pressure are in the face of the existing compressor very low. The same applies to an equally usable Hand pump for generating pressure.

The inventive object is also solved by a security device having the features of the claim 5. Terms used in their context, which are already above are also defined in the following as above understand.

there is a securing device for cargo with a loading floor, which has a loading surface and at least one outlet opening and at least one fixing system having at least one Survey proposed. The survey is from at least one Loading position in at least one fixation position can be transferred and rises in the fixing position from the outlet opening the level of the loading surface. To convict the survey from the loading position points in the fixing position the securing device according to the invention a mechanical actuator on.

Prefers can the mechanical actuator, which designed as a backdrop be or may have such, independent of current and operated without the presence of about a fluid pump such as a compressor. The operation can be easily by means of a lever - which in turn connected to the trunk lid of a motor vehicle be and operated by opening and closing the trunk lid can be - done. Due to an easily configurable Mechanics can be particularly maintenance-free and the safety device be made robust. Functional errors, such as those due to fluid leaks in fluid controlled devices can occur are excluded here.

In a preferred embodiment of the invention Safety device with mechanical actuator has the survey an elastic material.

The Providing an elastic material, in particular one as above discussed ausstülpbaren material, it allows the safety device to produce with a comparatively low manufacturing accuracy, because the elastic material manufacturing inaccuracies, which to Deteriorating the function of the mechanical actuator could compensate. this makes possible a reduced production cost and a cost saving in the manufacture of the security device.

In a further preferred embodiment of the invention Safety device with mechanical actuator is the survey in at least one section thereof as an open one or as one closed solid or hollow profile designed.

The Hollow profile advantageously allows a fixation of the load by extending from the outlet opening survey even if the outlet is part of Load is misplaced. Through the uninstalled part of the outlet opening can the survey due to their hollow profile and the associated Deformability in this embodiment, at least partially emerge from the outlet opening and fix the load. This also applies to the embodiments discussed above, which have a protuberance.

In a further preferred embodiment of the invention Sicherungsvorrich tion, the elevation or the protuberance on a material whose coefficient of friction or coefficient of friction is higher than the coefficient of friction or friction coefficient of a material in a region of the loading surface.

This serves the desired function of the safety device, which on the one hand a slight displacement of the cargo on the loading surface and on the other hand, a secure fixing of the cargo through the one or multiple surveys or protuberances. This is supported by the fact that the friction on the Loading surface less than at the elevation or protuberance is. Particularly preferred is a securing device, which a smooth as possible, highly wear-resistant loading floor surface with low coefficient of friction to facilitate an intentional shifting of the load and a fixing with as possible having high coefficients of friction. If an outlet opening is laid by load, the area lying below the load can the fixing device, which due to the dead weight of the cargo despite applied pressure not through the outlet opening can emerge, by training the contact with the load one additional, fixing effect due to frictional forces create between the elastic region and the load.

In a preferred embodiment of the present invention are the forces with which the fixing system from the loading position is transferred to the fixing position, so low determinable that damage to the cargo -. B. in the case of a flat-mounted glass with it parked Briefcase - can be excluded.

The inventive object is also solved by a motor vehicle having an inventive, In particular special a backup device described above. Since all the advantages discussed above also undiminished the motor vehicle according to the invention achievable are at this point to avoid repetition Refer to the above discussion.

In a preferred embodiment of the invention Motor vehicle has this means for automatic transfer from the loading position to the fixing position and / or vice versa on. For example, this facility can ensure that the Fixation system of the safety device when opening the Boot lid or the cargo area generally in the Loading position passes when closing the boot lid or when starting the engine on the other hand, goes into the fixing position.

This saves the user of the vehicle advantageous time and effort. In addition, with a suitable choice of criterion, when the fixation system should pass into the fixation position, avoided, that is forgotten, the fixing system, for example, before the start of a ride to activate (i.e., to bring into the fixation position), so that loaded cases or the like accidentally slip and damage can take.
