Description

The present invention relates to a kit with an additional floor with a plate-shaped body for a vehicle, in particular for a transporter, wherein the vehicle floor of the transporter has screw-in components that can be fastened by the vehicle manufacturer.

There are already kits available for installing an additional floor in the interior of vans. There are two specific types of design. One type of design includes an additional floor made of plywood that is glued into the vehicle. The other alternative includes additional floors, preferably made of plywood, that are attached to the floor of the van with separate screws, rivets or similar elements.

The disadvantages of an adhesive solution are that it is difficult to remove and that it pollutes the environment. If, for example, you try to remove the vehicle floor from the van, you will need to use chemicals or heat. The use of chemicals entails costs and disposal problems. The use of heat requires an adequate heat source and causes the entire vehicle to heat up, which is not desirable. The solution of anchoring the additional floor to the vehicle floor with separate screw-in components, such as screws, also has serious disadvantages. The screw-in components damage the paintwork and, in some cases, even the underbody protection of the vehicle. The susceptibility to corrosion is therefore significantly increased.

It is therefore the object of the present invention to releasably anchor an additional floor in the interior of a van or other motor vehicle using the screw-in components provided at the factory. This should also avoid damaging the vehicle, in particular the vehicle floor. Perforations in the vehicle floor should be avoided.

This object is achieved according to the invention in that the plate-shaped body has openings in the area of the screw-in components of the original floor, and that the kit has insert elements with at least one opening that fit into the openings.

" *Ji*

has a passage hole for the screw-in components, the thickness being less than the thickness of the plate-shaped body, at least around the passage hole. A positive connection is achieved between the screw-in component, the insert element, the additional floor and the vehicle floor.

This solution according to the invention prevents the need to drill holes or perforations in the vehicle floor in order to anchor the additional floor, which consists of a plate-shaped body, in the van. By using screw-in components already present in the vehicle at the factory to attach the additional floor, it is also possible to remove and re-remove the additional floor. A reduction in the value of the vehicle due to the installation and re-removal of the additional floor is thus avoided.

If at least one insert element in a special embodiment has at least one cranked edge, it is ensured that the additional floor can be easily attached to the vehicle.

It is particularly advantageous if a surface of the insert element facing the vehicle floor is located below a surface of the additional floor facing away from the vehicle floor, since in this particular design the additional floor has no further elevations. This is positive, since when loading a van, heavy objects are often pushed along on the additional floor. The protruding surface of an insert element would be disruptive here.

It is also particularly advantageous if, in a further embodiment, the upper edge of the additional floor is arranged substantially above the surface of the insert element. This has the positive effect of creating a flat loading area and the uppermost surface being formed by the additional floor. This prevents the insert elements from shearing off.

If, in a further variant, a part of the surface of the insert element facing away from the vehicle floor is formed below another part of the surface of the insert element facing away from the vehicle floor, the insert element extends on different levels, whereby a part of the insert element is close to

the vehicle floor. When inserting an installation element, tension can be applied, whereby the insert element can be pulled to the vehicle floor and the insert element thereby pulls the additional floor onto the vehicle floor.

It is also particularly advantageous if the opening has at least one step in the opening on the vehicle floor side. In such a variant, the opening has two different radii. These two radii ensure that the insert element can be easily inserted while simultaneously overlapping the hole in the vehicle floor for the screw-in component and the through hole. Small manufacturing errors can be cleverly compensated for here.

If, in another variant, the step in the opening is designed to be continuous, a force that is introduced into the additional floor via the step can be distributed over a larger area. The service life of the step and thus of the additional floor is significantly increased. The load-bearing capacity of the additional floor also increases considerably.

If, in a special design example, the cranked edge is designed to rest on the step on the additional floor, the force acting on the insert element is transferred via the cranked edge and the step to the additional floor. This makes it possible to screw the additional floor onto the vehicle floor.

It is also particularly advantageous if, in another variant, the insert element is fitted into the additional floor in a form-fitting manner. The force acting on the insert element can be transferred to the additional floor via such a form-fitting connection and the insert element can be mounted on site during assembly.

In one variant, it is particularly advantageous if the cranked edge has at least one counter-directional double-angle bend. The production of a cranked edge by means of a double-angle bend can be achieved industrially in a simple and cost-effective manner.

If, in a further variant, the cranked edge is designed to run all the way around an outer border of the insert element, the insert element can be moved on the heel, which means that production-related tolerances do not reduce the quality.

It is also particularly advantageous if the insert element has at least two tabs in a further embodiment, since such tabs can also be produced by milling and turning processes, and thereby efficiently transfer force from the insert element to the additional floor.

If the tabs are designed as elements that rest on the heel, a positive connection is created that can transmit a maximum force that is easy to calculate. The probability of failure of the insert element can therefore be easily determined.

If at least one of the tabs is designed to run all the way around the outside of the insert element in a variant, the surface area of the tab becomes larger, thereby increasing the force that can be introduced into the additional floor or into the insert element.

If the insert element can be connected to at least one spacer element in a further embodiment, the distance between the additional floor and the screw-in component can be varied. This significantly increases the flexibility of using an additional floor in different vehicle types.

If two spacer elements each have an opening aligned with an opening in the insert element, it is possible to create a multiple connection between the insert element and the vehicle in this design variant using two screw-in components and incorporating the spacer elements. The number of openings in the additional floor is thus reduced.

In another embodiment, it is particularly advantageous if the spacer element is made from a perforated plate. Such spacer elements are easy to manufacture. The costs are minimal.

If the plate is constructed from a disc, this plate can be purchased easily and inexpensively on the open market. Production capacity can be used for other purposes. This further reduces costs.

It is particularly advantageous if one variant of the kit includes a panel connection device. When using a panel connection device, it is easy to flexibly cover different lengths and widths in a vehicle with an additional floor.

If the panel connection device in one variant has a fitting tab on one panel to be connected and a groove on the other panel to be connected, two parts of the additional floor are cost-effectively connected to each other according to a tongue and groove principle.

It is particularly advantageous if the fitting tab in one variant has a center line that is arranged below the upper edge of a surface of the plate-shaped body and above the underside of the plate-shaped body. This ensures that the tab is arranged inside the additional base, which prevents the tab from breaking out of the groove or the groove from breaking out of the tab.

If, in a further embodiment, the groove has at least two webs, in this variant the groove can be manufactured by a simple milling process into the additional floor.

Alternatively, it is also advantageous if the groove has two webs of different lengths, as this prevents the individual components from being twisted against each other and installed incorrectly during assembly. This makes assembly quicker and safer.

If the webs in a variant have different thicknesses, this is advantageous because the loads on the additional floor are adjusted as required. It is therefore possible to distribute forces acting on the surface of the additional floor by means of a

larger web from one additional floor to the other. This reduces the risk of the additional floor breaking.

If, in one variant, the web arranged on the vehicle floor side is designed to be longer and thinner than the other web, this is advantageous because incorrect installation is prevented and maximum load-bearing capacity of the connection point is enabled.

If the additional floor in a variant has an end tab on at least one end side, the additional floor on the end side can be easily connected to the end tab below a cover strip on the locking element of the flap of the transporter.

If the end flap is arranged adjacent to or adjacent to the vehicle floor in one variant, the load is placed on the connecting element attached to the end flap rather than the end flap when the vehicle is loaded. This reduces the risk of the additional floor or end flap breaking.

If the insert element is designed in a variant from a stamped and bent part, the insert element can be manufactured easily and cost-effectively using existing machine equipment and existing know-how.

If the insert element is made of sheet metal, the raw materials can be selected from a wide range of offers.

In the following, embodiments of the present invention are explained in more detail with reference to a drawing. In the drawings:

Fig. 1 is a plan view of a two-part additional floor with openings, Fig. 2 is a plan view of an insert element with a through hole, Fig. 3 is a longitudinal cross section through an insert element,

Fig. 4 a cross-section along the shorter radius through an insert element, Fig. 5 a detail from Fig. 4 with a cranked edge,

Fig. 6 a detailed cross-section through the additional floor from Fig. 1 with a through hole,

Fig. 7 a cross-section through the connection point between the two additional floors with a fitting tab and a groove,

Fig. 8 a cross-section through the edge of the additional floor with a phase, Fig. 9 a cross-section through the end of an additional floor with an end flap,

Fig. 10 a cross-section through the assembly of an insert element with a screw-in component in an additional floor on a vehicle floor.

In Fig. 1, the kit is shown with an additional floor 1 and openings 2 therein. The additional floor 1 consists of two parts, namely the front floor 7 and the rear floor 8. There are four openings 2 in each of the front floor 7 and the rear floor 8. The openings 2 each have a recess 6.

The rear floor 8 has an end tab 18 on one side. On the other side, the rear floor 8 has a fitting tab 16. The fitting tab 16 engages in a groove 17 which is formed on the opposite side of the front floor 7. The groove 17 is made up of the upper web 10 and the lower web 11 (see also Fig. 7). The connection of the groove 17 with the fitting tab 16 enables a panel connection device 12.

In Fig. 2, the insert element 4 is shown with a through hole 3 and a cranked edge 5. The cranked edge 5 runs around the entire outer edge of the insert element 4. The insert element 4 has an oval outline.

Fig. 3 shows a cross-section along a longitudinal axis through the insert element 4. The cranked edges 5 are clearly visible. The insert element 4 is made from sheet metal in a punching and bending process. Alternatively, deep-drawing processes are also possible.

Fig. 4 shows a cross section through the insert element 4 along the shorter axis of symmetry through the insert element 4. The cranked edge 5 and the tab 21 are shown on the edge of the insert element 4. The tab 21 and the cranked edge 5 run around the entire circumference of the insert element 4.

Fig. 5 shows a detailed section X from Fig. 4. In this detailed section X, the cranked edge 5 is shown large.

The opening 2 is shown in Fig. 6. The opening 2 is located in the additional floor 1. The opening 2 is made up of a larger and a smaller cross-section. The larger cross-section is closer to a surface of the additional floor 1 than the smaller part of the opening. Because the opening 2 has a larger and a smaller part, a step 6 is formed. The step 6 is required by the cranked edge 5 of the insert element 4 in order to be able to transfer force from the insert element to the additional floor.

The panel connecting device 12 is shown in Fig. 7. One part of the panel connecting device 12 is located on the side of the front floor 7, the other part on the side of the rear floor 8. The fitting tab 16 is located on the rear floor 8, facing the front floor 7. The fitting tab 16 has a center line 13 which is located within the additional floor 1. The center line 13 is located below the upper edge 14 and below the surface 19 of the additional floor or the rear floor 8. The fitting tab 16 fits into the groove 17 of the front floor 7. The groove 17 is formed between the upper web 10 and the lower web 11. The upper web 10 is located on the side of the upper edge 14. The upper edges 14 of the front floor 7 and rear floor 8 are flush when installed.

The underside 15 of the front floor 7 and the rear floor 8 are also flush when installed.

Fig. 8 shows the cross-section of the edge of the additional floor 1, which has a phase 9 on the surface 19.

Fig. 9 shows an end tab 18 at one end of the additional floor 1, in particular at the rear floor 8. The end tab 18 is located on the underside 15 of the additional floor 1.

Fig. 10 shows the assembled state of the insert element 4 in the additional floor 1 for fastening to the vehicle floor 24 using a screw-in element 23. The screw-in element 23 is a screw provided at the factory. A spacer element 22 is provided between the screw head and the insert element 4. The flow of force from the vehicle floor 24 runs via the screw-in component 23, the spacer element 22, to the insert element 4, to the tab 21 of the insert element 4 and the bent edge 5, with the bent edge 5 and the tab 21 transferring the force to the additional floor via the shoulders 6 of the opening 2.

To install the additional floor in the van, first the front floor 7 is placed in the vehicle. The openings are aligned so that after the screw-in components 23 are removed from the vehicle, they end up flush with the holes in the screw-in components 23. The insert elements 4 are then inserted into the openings and flush with the holes for the screw-in components 23, with the through holes 3 of the insert elements 4 aligning with the holes for the screw-in components. After the spacer elements 22 have been placed on the insert elements, the screw-in component is screwed back into the vehicle floor 24. The front floor is fixed to the vehicle floor 24 by supporting the sheet metal insert element 4 on the shoulder 6 of the additional floor. The rear floor 8 is then pushed with its fitting tab 16 into the groove 17 of the front floor 7. The insert elements are inserted into the openings in the rear floor and fixed to the vehicle floor 24 together with the spacer elements and the screw-in components 23. The end tab 18 of the rear floor 8 is covered by a separate component.
