Description

Technical field

[0001] The present invention relates to a self-centring system for receptacles in pull out cabinets.

Background art

[0002] In prior art it is known that different storage systems comprising different internal frame structures for shelf systems, wardrobe systems, kitchen cabinets etc. are produced and eventually assembled. These storage systems comprise an outer housing and a frame structure arranged inside the outer housing. The frame structure supports internal shelves, trays etc. To decrease the manufacturing costs of the storage systems the manufacturers adapt a few frame structure models to fit in as many sizes of shelf systems, wardrobe systems, kitchen cabinets etc. as possible. This gives rise to that a specific frame structure in some way need to be adapted to the actual dimension of the specific outer housing by means of adjustment features such as for example distance means.

[0003] The outer housing is preferably made of fibreboard, medium-density fibreboard (MDF) or any other suitable outer housing material. Depending on the dimensions of the storage system, especially the material thickness of the outer housing material, the width of the frame structure need to be adjusted to various sizes in order to fit properly into the outer housing.

[0004] In prior art the adaptation of the width of the frame structure is conducted by adding one or more distance means between the frame structure and the outer housing. Generally the distance means are only added to one side of the frame structure. Depending on the height of the storage system, one or more positions along the height of the frame structure may need to be adjusted. The distance means come in different sizes in order to be able to correctly fill the gaps in between the frame structure and the outer housing due to different material thicknesses of the outer housing material.

[0005] In case the person who assembles the storage system is not a skilled worker, it may be difficult for the person to judge which size of the distance means are to be used to obtain the desired total width of the frame structure, and as a result the frame structure may be mounted in a skew manner and give rise to malfunction.

[0006] Another drawback in using distance means is that, since the manufacturer beforehand does not know which specific width the frame structure needs to be adapted to, the manufacturer has to send a surplus of distance means of various sizes to the end consumer or the person who assembles the storage system. This gives rise to an unnecessary waste of unused distance means that eventually are disposed of.

[0007] Furthermore, it is relatively difficult and time consuming for the end consumer or the assembly personnel to install the distance means in order for the frame structure to be correctly installed in the outer housing of the storage system.

[0008] The frame structure most often comprises some sort of receptacles which carry goods. These type of goods could in a domestic environment be clothes, foodstuff, bathroom necessities, tools etc. In an industrial or office environment it could be other type of goods. These receptacles need to be well centred and positioned with regards to the inner sides of the outer housing, as the receptacles are often installed in a pull out cabinet. The frame structure provides the means for the positioning of the receptacles. If the position of the receptacles is wrong the receptacles may be skewed with regards to the inner sides of the housing or too close to one of the inner sides of the housing. As a result it could be difficult or impossible to pull in and out the receptacles of the outer housing.

[0009] It is therefore desirable to accomplish a centring system for receptacles in pull out cabinets, which is inexpensive to manufacture, which does not include too many separate components, which is easy for the end consumer or any other person to install, which provides the possibility to be installed in a non-skewed manner, and which obsoletes distance means of various sizes.

Summary of invention

[0010] An object of the present invention is thus to accomplish a centring system for receptacles in pull out cabinets, which is inexpensive to manufacture, which does not include too many separate components, which is easy for the end consumer or any other person to install, which provides the possibility to be installed in a non-skewed manner, and which obsoletes distance means of various sizes.

[0011] According to one aspect the invention concerns a self-centring system for receptacles in pull out cabinets. The frame structure provided in a cabinet body comprises first and second brackets, first and second rails, at least one receptacle. The first bracket is fixedly attached to a first lateral side of the cabinet body and the second bracket is fixedly attached to a second lateral side of the cabinet body. The first and second rails are slidably attached by means of sliding means on to the first and second brackets, such that the first and second rails are slidable in and out of the cabinet body. The receptacle is attached to the first and second rails. The self-centring system comprises a first and second fastening means comprising a main portion from which hook means extend and which hook means of the first fastening means are arranged to at least partially enclose a first portion of the receptacle and to grip a connecting part of the first rail. The hook means of the second fastening means are arranged to at least partially enclose a second portion of the receptacle and to grip a connecting part of the second rail, permitting the receptacle to attach to the first and the second rails and consequently to be self-centring between the first and second lateral sides of the cabinet body.

[0012] An advantage with the system is that it enables the receptacle to self-centre between the first and second lateral sides of the cabinet body. Furthermore the included components are few and inexpensive to manufacture. The system is very easy for the end consumer or any other person to install in a non-skewed manner. Additionally the distance means of various sizes are made obsolete.

[0013] The above system may be configured according to different optional embodiments. For example the first and the second fastening means may each be provided with a main portion, a pin and first parts of the hook means. The pin and first parts of the hook means extend in the same direction and are arranged on and substantially perpendicular to the main portion. The pin of the first fastening means is arranged to engage with a first hole provided in the receptacle and the pin of the second fastening means is arranged to engage with a second hole provided in the receptacle.

[0014] An advantage with the solution is that the pin and the first parts of the hook enables the receptacle to even better self-centre between the first and second lateral sides of the cabinet body.

[0015] According to an embodiment of the invention, the hook means of the first and second fastenings means may comprise second parts arranged at end parts of the first parts of the hook means extending in a substantially perpendicular direction in relation to the first parts of the hook means, and are arranged to grip the connecting parts of the first and the second rails.

[0016] An advantage with the solution is that the second parts of the fastening means fixedly attach the receptacle to the first and second rails, and that it prevents the receptacle to lift upwards if the end user would pull the receptacle in that direction.

[0017] According to an embodiment of the invention the first and second holes of the receptacle may be oblong, extend in a diagonal manner in between the first and second lateral sides of the cabinet body and mirror each other in an imaginary centre line of the receptacle in a lateral direction. An overall length of the first and second holes of the receptacle is long enough in permitting the pin of the first and second fastening means and thus the receptacle to travel an adjustment distance in a transverse direction.

[0018] An advantage with the solution is that it permits the pin of the first and second fastening means and thus the receptacle to travel an adjustment distance in a transverse direction. This permits the receptacle to even better self-centre between the first and second lateral sides of the cabinet body.

[0019] According to an embodiment of the invention the receptacle may be provided with first and second pins, which extend from a first end of the receptacle towards the first and second rails respectively. The first rail may be provided with a first aperture within which the first pin engage, and the second rail may be provided with a second aperture within which the second pin engage.

[0020] An advantage with the solution is that it permits the receptacle to even better self-centre between the first and second lateral sides of the cabinet body and that it is fixedly attached to the first and the second rails.

[0021] According to an embodiment of the invention the first and second apertures of the first and second rails may be oblong in shape, extend in the transverse direction and wherein an overall length of the first and second apertures is long enough in permitting the first and second pins of the receptacle and thus the receptacle to travel an adjustment distance in a transverse direction.

[0022] An advantage with the solution is that it permits the first and second pins of the receptacle and thus the receptacle to travel an adjustment distance in a transverse direction. This permits the receptacle to even better self-centre between the first and second lateral sides of the cabinet body.

[0023] According to an embodiment of the invention the receptacle may be provided with first and second tongue-shaped projections, which extend from a second end of the receptacle towards the first and second rails respectively. The first rail may be provided with a first receiving device within which the first tongue-shaped projection engage, and the second rail is provided with a second receiving device within which the second tongue-shaped projection engage.

[0024] An advantage with the solution is that it permits the receptacle to even better self-centre between the first and second lateral sides of the cabinet body and that it is semi-fixedly attached to the first and the second rails.

[0025] According to an embodiment of the invention the first and second receiving devices may be long enough in a transverse direction in permitting the first and second tongue-shaped projections and thus the receptacle to travel an adjustment distance in a transverse direction.

[0026] An advantage with the solution is that it permits the first and second tongue-shaped projections and thus the receptacle to travel an adjustment distance in a transverse direction. This subsequently results in the receptacle to even better self-centre between the first and second lateral sides of the cabinet body.

[0027] According to an embodiment of the invention the receptacle may be provided with a first and second set of apertures. The hook means of the first fastening means extend through the first set of apertures. The hook means of the second fastening means extend through the second set of apertures.

[0028] An advantage with the solution is that it permits the receptacle to even better self-centre between the first and second lateral sides of the cabinet body.

[0029] According to an embodiment of the invention the first and second set of apertures of the receptacle may comprise a width extending along lateral sides of the receptacle. The width is larger than a width of the first and the second fastening means.

[0030] An advantage with the solution is that it permits the receptacle to even better self-centre between the first and second lateral sides of the cabinet body.

[0031] The outer housing material often varies in thickness in between 16 and 19 mm. However, the thickness can both be smaller and greater than these dimensions.

[0032] With regards to mentioned adjustment distance in a transverse direction, the adjustment distance is for instance 6 mm when the outer housing material varies in thickness between 16 and 19 mm, which often is the case. The formula for calculating the adjustment direction would be 2 x (maximum thickness - minimum thickness of outer housing material) which for mentioned thicknesses equals 2 x (19-16) = 6 mm.
