To create a metal locker which is simple and inexpensive to manufacture, takes up little space in transport and can be recycled without difficulty, it is proposed that the outer mantel (9, 10, 11) of each of the hollow shaped elements (6, 7, 8) should be formed from the sheet metal of the side walls (3, 4, 5) by multiple folding by which the inner spaces elements (12, 13, 14) of the shaped elements are substantially defined.

Description

The invention relates to a metal cabinet according to the preamble of claim 1.

Such metal cabinets are used, for example, as lockers in the changing rooms of swimming pools, sports facilities, Schools or used in industry. The metal cupboards are mostly made of sheet metal parts and show on the front of the cabinet two vertical ones Hollow profiles on the end faces of the side walls are arranged. These profiles often form with cross profiles in the roof or floor area a frame in which one usually lockable cabinet door can be used.

When manufacturing the metal cabinet are considered Prefabricated hollow profiles to the End faces of the cut side walls welded, to create a stable and stable connection. In Cross sections are arranged in a similar manner. The assembly the metal cabinets are made by the manufacturer himself, automated welding systems are often used. After assembly, the metal cabinets are both out optical reasons as well as protection against corrosion paint. Metal cabinets also painted using the immersion method can in the area of corner joints and welds Have defects that lead to corrosion to lead.

In the case of metal cupboards made of aluminum, it is disadvantageous that the Hollow profiles and the side walls made of different Alloys exist. This requires increased effort when returning metal cabinets to be scrapped in the recycling cycle, since the side walls and the Hollow profiles are to be separated by type.

The invention has for its object a metal cabinet of the generic type in such a way that he simple and inexpensive in simple work steps to be produced and returned to the recycling cycle is easy to recycle.

This object is achieved according to the features of claim 1 solved.

The hollow profiles are in one piece with the side walls or trained with ceiling and floor and are in a bending process the sheet is simply molded onto the side wall. The Sheet metal of the side wall is between an upper and lower tool clamped flat, with the one to be bent Edge protrudes and from a bending tool accordingly is turned; this process is repeated several times until the desired hollow profile simply by multiple bending is fully trained. A welded connection between Wall and a separate hollow profile is not required. The type of Bending process enables the processing of coated, painted, anodized or polished sheets made of steel, aluminum and other metals. Such sheets are used as finished material, for example on rolls delivered and can be processed from the roll. The Sheet metal surface is neither when punching or cutting the side walls while bending to manufacture the Hollow profile violated, so that a final Complete painting of the metal cabinet can be omitted. The side wall with a hollow profile molded onto it can be inexpensive manufactured and space-saving as a single component for To be transported to a site Final assembly to be assembled into a metal cabinet. Both the storage volume and the transport volume is lowered. The metal cabinet can also, especially if it made of aluminum, easily recycled will. The side walls and the hollow profiles consist of the same alloy, so that sorting not applicable.

The free longitudinal edge of the profile jacket is preferably located of the hollow profile on the sheet metal of the side wall, so that a completely closed profile cavity is formed. Entry of dirt and moisture into the profile cavity is avoided. That led back to the side wall free end of the sheet expediently extends approximately parallel to the wall plane of the side wall. The side wall can via a vertical step in two wall areas be divided, the wall levels of both wall areas offset in parallel, preferably by the amount of the wall thickness, lie to each other. That led back to the side wall free end of the profiled sheet metal can extend up to extend the step between the two wall areas.

A wall section of the profile jacket advantageously lies in the level of the side wall, in particular the profile cavities of both hollow profiles in the between the two side walls lying area. The hollow profiles extend therefore in the direction of the cabinet interior Inside of the side walls, so that the outer sides of side walls and hollow profiles are arranged in one plane and easily multiple metal cabinets with adjacent Side walls can be placed side by side.

The hollow profile can be on at least one side wall the wall plane has two mirror-symmetrical halves, so that the hollow profile towards both sides of the wall the side wall extends. The side wall can be in this Case as a partition between two outside Side walls can be arranged.

The metal cabinet expediently has a rear wall which forms a one-piece component with a side wall and is in particular molded onto the sheet metal of the side wall. By bending the sheet accordingly, it is possible to form the hollow profile at one end of the side wall and the the area of the side wall opposite the hollow profile bend about 90 ° and form as a rear wall. Hollow profile, side wall and rear wall can thus be a common Form part.

On the side facing away from the side wall of the stiffening hollow profile, a design profile can be defined, which is essentially over the entire length of the Hollow profile runs and formed narrower than this is. This design profile is essentially one closed box profile or the like. which consists of a coated, varnished, polished or anodized sheet is bent. The design profile, which like the stiffening hollow profile as the cabinet opening or the Cabinet door surrounding frame can be arranged is a design element for color combination. Of the Cabinet body is kept in a basic color, while that Design profile available in a wide range of colors pose is.

The metal cabinet 1 shown in perspective in FIG. 1 consists in particular of aluminum, sheet steel, stainless steel sheet or the like. And has two side walls 3, 5, the their area facing the cabinet front 2 each are connected to a hollow profile 6, 8. A rear wall 28 is arranged between the side walls 3, 5; about extends parallel to the outer side walls 3, 5 an intermediate side wall or intermediate wall 4 whose area facing the cabinet front 2 a hollow profile 7 is also arranged. Like the top view can be seen in Figure 2, is between two neighboring Hollow sections 6, 7 and 7, 8 each have one Cabinet opening formed, into which a cabinet door 15 is inserted can be.

All walls, floors, ceilings and cupboard doors are useful the metal cabinet from the end product, coated or treated sheets. In addition to a sound absorbing Coatings are easy to clean and corrosion-resistant Coatings advantageous. The starting sheet for the cabinet parts can also be a corrosion-resistant Wear varnish or be anodized, which is advantageous both surface sides are coated or treated, see above that also the inner wall of the profile cavities from corrosion is protected. The starting sheets are cut or when cutting to the final dimensions of the side walls and especially in the bending process for the production of the hollow profiles not hurt on their surface.

To create an easy to manufacture metal cabinet, which takes up only a small transport volume and is light is to be recycled, the profile jacket 9, 10, 11 each Hollow profile 6, 7, 8 from the sheet metal of the side walls 3, 4, 5 shaped. The profile cavity 12, 13, 14 is advantageous in essentially closed. The hollow profiles and the side walls form a one-piece component, the hollow profiles by repeatedly bending a marginal cut at the Side wall plate are molded. Sidewall and hollow profile therefore form a solid, coherent unit; Connection work such as welding or fastening through mechanical connections are eliminated. So constructed Metal cabinets are easy to recycle as one Separation according to different types of material is not necessary can. The metal cabinet is easy to disassemble on site, for example in changing rooms of sports facilities, swimming pools or the like, quick and easy to assemble. The Hollow sections with their essentially closed Cavity 12, 13, 14 ensure high stability and ensure the installation of hinges and locks to insert lockable cabinet doors 15. The in Profile jacket recesses 46 to be provided for the bolt can be used when punching the side wall or when bending of the profile.

The ceiling and floor of a metal cabinet are formed in the same way as described for the side wall. The Horizontal cross profiles perpendicular to the side walls are attached to the sheet metal of the ceiling or bent over the floor. The hollow profiles and the cross profiles form a stiffening frame, the corner connections through special connection measures such as plugging, Screws, embossing or the like can be joined together.

The free end 16, 17, 18 of the profile jacket is expediently located 9, 10, 11 forming sheet on the respective side wall 3, 4, 5, so that a completely enclosed profile cavity 12, 13, 14 is formed and penetration of Dirt and moisture is prevented. The free end 16, 17, 18 advantageously extends approximately parallel to the respective wall levels 19, 20, 21 of each side wall 3, 4, 5 and can also be specified on the side wall (Fig. 3.). In the profile jacket 9, 10, 11 of each hollow profile in the area between two adjacent side walls Recesses 46 made in the hinges and Locks for the cabinet doors can be used. The free ends 16, 17, 18 of the side wall panels are located flat on the respective side walls and extend spread over an area approximately half the depth of the Hollow profiles - measured in the direction of the side walls between Cabinet front and rear wall - corresponds.

In the same way lies the Wall 25 of the profile jacket 11 in the wall plane 21 of the other outer side wall 5. whose profile cavity 14 is located also on the side facing the intermediate wall 4. This training makes it possible to have any number of metal cabinets side by side right next to each other to be arranged without being lined up by the hollow profiles to hinder.

The middle side wall 4 designed as an intermediate wall lies approximately parallel to the outer side walls 3 and 5 and divided the interior of the cabinet into two roughly the same large sub-rooms that can be used separately. The hollow profile 7 formed in one piece with the intermediate wall 4 is in relation to the wall plane 20 of the intermediate wall 4 in two approximately mirror-symmetrical halves 26, 27 divided. Every half 26, 27 is again approximately mirror-symmetrical to the external hollow profiles 6, 8 arranged and has approximately the same shape. The cross section of the outside Hollow sections 6, 8 or each half 26, 27 of the middle Hollow profile 7 is approximately rectangular in plan, in particular square with the back of the cabinet facing profile side triangular at an acute angle approaches.

In each side wall there can be a preferably vertical one Be introduced that the side wall in two Wall areas divided. In Fig. 4a is the middle and an outer side wall with the associated hollow profiles 7, 8 shown. Each wall has the vertical one Step 22, 23 on the wall in two areas 4a, 4b and 5a, 5b divided. 4b shows an enlarged view the transition area between the two wall areas the middle side wall. Each wall area 4a, 4b lies in a wall plane 20a, 20b which is offset parallel to one another are. The amount of the offset preferably corresponds to that Wall thickness b of the side wall; the free end 17 of the returned and lying flat against the side wall and advantageously attached sheet extends to vertical stage 22, due to of the offset by the amount b between the wall areas 4a, 4b the free end 17 in the same wall plane 20a as the wall area 4a facing away from the hollow profile. A Wall side 47 of wall area 4a is therefore with a Wall side 48 of the free end 17 in a common Level. In the same way, the external ones Side walls 3 and 5 may be formed.
