Description

Multi-element base for devices electric, particularly for washing machines.

The invention relates to a composite base for electrical appliances, in particular for washing machines or the like, according to the characteristics of the claim Independent.

Electric washing machines known for use Domestic are usually made as loading machines front or top loading machines, being the embodiment more frequent front loading. In this case, on the front face of the machine there is a swing door, usually made of glass, to through which the clothes are introduced into the machine and through which can be removed again after washing. The front-loading versions present among others the advantage of a relatively simple design and construction. It also turns out advantageous in this embodiment which due to its plate flat and smooth upper is suitable as both countertop and also to be installed in a kitchen under a countertop. There is also the possibility of placing, for example, a dryer on top of the washing machine, saving space in this way placement and installation. Now an inconvenience nothing despicable of front loading machines is that the loading and removal of clothing can only be done in position crouched or squatted by the person driving it, due to the relatively low arrangement of the front door.

Among other things, precisely because of this inconvenient the so-called loading machines were developed top, whose wash drum is accessible from above and that they are loaded and emptied from above through a porthole of several parts The disadvantage of top-loading washing machines is their more complex construction and the impossibility of placing things on The upper face of the machine. They are also not suitable for install them in a line of kitchen appliances.

Since washers and dryers are often they install in the basements and in the basements of these houses multifamilies are arranged a series of machines one next to the other, these are often placed on top of a base to facilitate the loading of the machines. For stability reasons, These bases are usually work or cast in concrete. The edge surrounding them prevents machines from falling even if they have a very unbalanced march and from it some movements are derived of intense vibration. These masonry bases or castings of concrete have the disadvantage that its construction is relatively expensive In addition they cannot change places and neither They are suitable for placing in the bathroom or kitchen a dwelling

A body is known from DE 94 19 048 U in the form of a drawer on which rests a container that also It is shaped like a drawer, with perforated side walls and about guide rails that allow it to be removed. Upper body edge It is made as a seat for the washing machine, which is placed in such way in this seat that remains on the body without the possibility of displacement.

The invention aims to perfect a base for front-loading electrical appliances, which can be changed of location.

This objective is solved by characteristics of the independent claim. In accordance with the invention, a base is composed of four side parts assembled orthogonally with each other, which in assembled state form a firm and solid base to lift a washing machine, a tumble dryer or similar The side parts of this base are preferably of a plastic material, for which it results Especially suitable recycled plastic. These side parts Recycled plastic can be manufactured economically in large quantities, for example, as pressed or sintered parts.

The base object of the invention for machines electric, particularly for washers and dryers, presents especially the advantage that in its unarmed state you can handle easily due to its relatively low weight and The small packaging dimensions. Instead, instead of use, the base that can be mounted in a very short time, constitutes a solid support for a washing machine or similar, which having a height of about 40 to 60 cm raises the filling height of a front loading machine to an area of approximately one meter Tall. In this way it is easy to load and empty the washing machine and / or dryer through the front cover without that the person who drives it has to adopt a hunched posture or squatting This loading height especially facilitates Older people operating the washer and dryer.

The armed base presents on its surface upper seat guiding corners that prevent an appliance Electric placed on top can be left laterally. In the holes in the base legs can be screwed in either height-adjustable support feet or the base can be screwed to the ground. The flat side faces are shaped in such a way that every two lateral parts can be placed on top of each other saving space, without sharp or sharp parts protruding live This stacked in pairs also allows storage and simple stacking for sale purposes. In this way there is also the possibility of stacking and packing the side parts in units of sale of four pieces each.

Other advantages and preferred embodiments can be deduced from the subclaims and the description of the figures.

Two examples of especially preferred embodiment of the composite base object of the invention, by means of figures 1 to 10b of the drawing. The parts The same have the same references in principle and partly not They are explained repeatedly.

Figures 1 to 6b show in various views and details a composite base object of the invention for washing machines, dryers or the like, in a first embodiment.

To do this, figure 1 shows a view in perspective of a base 4 object of the invention that has placed on top of a washer 2, a dryer or similar. The base 4, which in the represented embodiment example is assembled based on four individual side parts 41, 42, has a square plan with a section that narrows upwards, that is, the base is wider below than above. Base 4 carries on its four corners made as support feet two feet high adjustable 44; in the example shown these are bolts threads that can be adjusted in height by the head hexagonal, and immobilize by means of a locknut 45. In its part upper, the base 4 is made as a support surface for a 2 or similar washing machine that can be placed on top and presented in its edges of guiding corners 48 that prevent running machine 2. Machine 2 itself rests on an edge of support 47, formed by the upper narrow faces of the four laterals 41, 42. There is also a drawer 46, which may be optionally present and that can be introduced in a housing corresponding of large surfaces of a lateral part 41. Since all four side parts have the same hole central, the drawer 46 can be inserted from the side, being guided in a simple way by congruent holes. The drawer 46 is You can also conveniently use as support for a basket of clothes. The drawer 46 is in a state preferably introduced a support on the opposite side.

In figure 2 the base is represented again 4 object of the invention with the washing machine 2 placed on top in three frontal views, in three collapsed views according to the ISO standard.

Figure 3 also shows one of the four side parts 41, 42 of the base 4 object of the invention, seen in perspective. The flat side part 41 is essentially shaped trapezoidal with rectangular section. The side of the side 41 that looks down is longer than the support surface 412 that look up and that in assembled state of the base 4 forms a straight section of the peripheral seat edge 47 for the washing machine 2. The front surface 411 of the flat side part 41 has the housing or hole 461, in which in the assembled state of the base a drawer 46 can be inserted eventually. So that the parts laterals 41, 42 can be joined together orthogonally and hold each of the side parts 41 securely together, 42 is provided with flat hooks 431, 432, which fit the corresponding slot-shaped holes 433, 434 of a part contiguous side Thus, on the narrow side surface 413 vertically oriented to the left in the view in perspective depicted in figure 3, two are arranged hooks 431, 432 projecting at a right angle to this surface lateral 413, one over the other, whose sections angled 90º towards Below you can enter straight into the corresponding holes 433, 434 as a groove of the adjacent side part 42, for push them down later. In the finished state, the section angled down each hook 431, 432 fits in state assembled finished, respectively, in a section 435 moved towards back with respect to the front surface 411, under the hole in the form of groove 434, so that the narrow surface vertical parallel to the lateral surface 413 of each of the hooks 431, 432, ends respectively with the front surface 411 of the adjacent side part 42 which forms an angle of 90 °. Is that is, the length of the hooks 431, 432, in which they protrude from the lateral surface 413 corresponds approximately to the height of the side surface section or width of the lateral surface 413.

Figure 4 shows the side part 41 according to the Figure 3, in three front views, where in the side view a plan view of the lateral surface 413 is shown on the right from which the hooks 431, 432 stand out. In the top view left of figure 4 are recognized on the right on the surface front 411 the two holes 433, 434 in the form of a groove, arranged stripped one on top of the other, with its section 435 respective lower and set back. In these sections 435, set back towards the front surface, the sections that point towards below the hooks 431, 432. The bottom left view shows a plan view from above on the side part 41 with the edge or flat seat surface 47 facing up, which forms a part of the support surface for the washer placed on the basis 4. In this view the guiding corner 48 is recognized, raised with respect to the seating surface 47, which ensures the washing machine to prevent it from running sideways.

Figure 5 shows two side parts of the base object of the invention, perspective views as they have been to assemble Each side part 41, 42, bears on one side two hooks 431, 432 and on the other side two holes corresponding 433, 434 in which they can hook the hooks. Figure 5b shows a base 4 finished assembling, seen in perspective.

Figure 6a is a perspective view of two side parts 41, 42, stacked flat on top of each other, represented in the transport position. This way you can place two flat side parts on top of each other, to form a packing unit, to pack them properly. For this the side parts are placed on top of each other rotated respectively 180 °, such that the seat edge 47 that widens inward boundary with the bottom side of the other side. Figure 6b shows the stacking position of the side parts with each other through two front views.

Figure 7a to 10b show a composite base according to the invention for two washers, dryers or the like placed next to each other, in a second example of realization.

To do this, figure 7a first shows a perspective view of a variant of the composite base 4 object of the invention with two electrical appliances placed one next to the other. The main difference with respect to the first form of embodiment according to figures 1 to 6 lies in the side parts anterior and posterior 43 that have double width. The parts lateral 41, 42 left and right correspond to the side parts described above of a simple base 4 to place on top of a machine Due to the double side parts 43 width a double bearing surface is also obtained, so that on a base 4 two machines can be placed one next to the another, for example, a dryer and a washing machine.

Figure 7b shows the base object of the invention according to figure 7a in three front views. Sight upper left shows a front view of base 4 with the 2 machines placed on top; the view next to you on the right shows a lateral front view of the left side of the view upper left. The bottom view finally shows a view on the floor of the machines 2 and the base 4 protruding from its plant, with drawers 46 extended forward.

Figure 8a shows a side part 43 of double width of a base object of the invention according to the Figure 7a, perspective view, Figure 8b shows the part side 43 according to figure 8a in four front views. The essential difference from the narrower side 41, 42, represented in figures 3 and 4 is in double width and in the upper recess in which a connecting piece can be hooked. In assembled state, this connecting piece forms the support surface of the side edges facing each other of the machines placed on the base 4.

Figure 9a shows an assembly drawing in perspective of a base according to the invention according to figure 7a, where the connection piece 49 is especially clear here hooked up on the finished assembly base. The Figure 9, 9b shows two side pieces 42, 43 of the object base of the invention, perspective views, as assembled each. Here, the recess 462 provided in the double width side portions 43, in the center of its upper seating surface 412 and extending through entire section of the side 43. Also centered on this recess 462, but in a direction parallel to the front surface 411, a bridge 463 is planned, which fits into the corresponding accommodation of the face facing down and settling on the recess 462 of the connecting piece 49. The flat connecting piece and elongated 49 presents on its upper face and at the ends longitudinal a guide corner 491 facing upwards of so that a connecting piece, placed in the housings 462 of two side parts 43 facing each other, forms an edge of right or left seat for each of the two surfaces of support of electrical appliances that is located at the same height that the peripheral seat edge 47, formed by the surfaces of seat 412.

Figure 10a shows a perspective view of two flat width 43 side parts flat stacked one envelope the other in transport position, which thus form a Packing unit. In figure 10b the two side parts are seen 43 stacked one on top of another according to figure 10a in two views front. In this packing unit the piece is also contained of connection 49, which will be hooked at the top in the side parts 43 double width

In addition to the two embodiments represented from base 4, single and double width, fits also the possibility of providing expansion equipment through which can be expanded at will a simple or wide base. Thus, for example, they can be provided on an already completed basis 4 additional hooks 431, 432 or slot-like holes 433, 434, in which a lateral part 41, 42 is respectively engaged, which in turn, it joins at its other end with another lateral part 41, 42. In this way it can be formed from seven side parts of simple width 41, 42 a double width base; from ten lateral parts 41, 42, a triple-width base, etc., on the which can therefore be placed several electrical devices, washing machines, dryers or similar. With this method they can be mounted Rows of bases of any length, quickly and reversibly, which can represent an advantage especially in laundry large multi-family houses.

In the case of a typical width of a washing machine conventional front loading, about 60 to 65 cm, is achieved with a base according to the described embodiments, with a height of about 50 to 60 cm, a height of the loading mouth of the washing machine of approximately 1 meter. This ensures a convenient access to load and empty the washer and dryer, without a crouched or squatting posture is necessary.

As a material for the side parts of the base object of the invention is particularly suitable a injection molded plastic, as this way you can also perform angular and contoured contours without problem in foundry molds.

However, there are also many others procedures that are suitable for manufacturing the base well either as a whole or as parts of the base. For example here blow forming is also suitable, in particular the extrusion blow molding. This procedure has the advantage that the pieces can be manufactured very economically. The preferred plastic for this is a dyed polypropylene. The blow-formed parts are waterproof, depending on the fabrication process.

Due to the reduced unit weight of the pieces formed by polypropylene blowing, these are filled, preferably after finishing the blowing process and the molded part has cooled down, especially when performing final assembly of the base on the client and preferably after assemble all the individual pieces, using water, sand or other material that can be poured or flow that has a weight specific high enough. If the different pieces only they are filled with water and / or sand in the client after assembly final, then all the pieces have a reduced weight for the transport and due to its low weight all individual parts are They can mount simply.

As an alternative to blow molding, the core pieces can be manufactured respectively as symmetric semi-packages, which are joined by welding or gluing or in some other way to obtain a tight hollow bodies.

To do this, each piece of the base has a closing hole, preferably located on the face upper base. In this way you can obtain your own weight raised from the base, despite the light plastic material, lowering the center of gravity of the base assembly and the electrical appliance placed on the base.

Another preferred material for the base object of the invention is recycled plastic, that is, plastic that has been recovered from material that had already been used. This plastic Recycled especially has the advantage of being available in Large quantities as cheap raw material. A recycled plastic that is not of pure quality, that is, that it is composed of different kinds of plastic, for example, also with proportions of duroplastic, usually not suitable for work by an injected casting procedure. This plastic can be first shred or fragment, then giving the desired shape by pressing or sintering. By pressing or sintered the plastic is given a consistency similar to baked. In addition to this, this plastic has the advantage of having a significantly higher own weight compared to a piece manufactured by a plastic blowing procedure.

The above description of the examples of embodiment according to the present invention is for purposes only illustrative and is not intended to limit the invention. Within the framework of the invention fits rather various variants and modifications without abandon the scope of the invention and its equivalent.
