A method for assembling a pushing device includes mounting the holders on the running rails and placing a base on each of the holders.
Description
- The present invention relates to a pushing device for furniture or household appliances, with a first pull-out guide and a second pull-out guide, wherein each of the two pull=out guides comprises a stationary guide rail and at least one running rail movable relative to the guide rail, and a front holder and a rear holder is fixed to each running rail, and a method for assembling a pushing device.
- AT 11 720 U2 discloses a drawer with an adapter for establishing a snap-in connection between a pull-out guide and a drawer. This facilitates the assembly of the drawer on the movable rail of the pull-out guide. The drawer forms a preassembled unit with base, rear panel, front panel and side panels, which are fixed to each other by fastening means. The fasteners are adapted to the geometry of the individual elements of the drawer, and the production of such a drawer is therefore complex and requires a large number of components that are adapted to the respective drawer.
- It is therefore an object of the present invention to provide a pushing device for furniture or household appliances which is simple in design and easy to assemble. This object is achieved with a pushing device having the features of
claim 1 and a method having the features ofclaim 13. - In the pushing device according to the invention, holders are fixed to two pull-out guides, namely one front holder and one rear holder. The pushing device comprises a base that rests on all four holders and is secured against displacement by stops on the holders. Because of this, the base can be mounted easily by placing it loosely on the four holders. Further fastening means for a force-locking fixation are not necessary, so that the base can be placed on the four holders after mounting the pull-out guides. For example, the base can be made of wood, plastic, glass or other materials. The bottom can also be formed as a grate or grid.
- Preferably, each holder angularly surrounds a corner of the bottom at the edge. In this way, the floor can be secured against displacement at each corner by one of the holders, whereby the upwardly projecting angular walls on each holder can be arranged with clearance to the edge of the floor in order to compensate for tolerances. In the area of the corner, each holder can optionally be rounded. Further protection against displacement can be provided by the fact that the support on each holder for the floor is made of an elastic or rubberised material.
- In a preferred embodiment, a groove-shaped receptacle is formed on each holder for inserting a lower end section of a side wall. This allows the two side panels to be easily assembled by inserting them into a groove-shaped receptacle on the front holder and into a groove-shaped receptacle on the rear holder. Furthermore, each holder may have a further groove-shaped receptacle, preferably aligned at right angles thereto, for insertion of a lower end portion of a rear wall or a front panel. This allows fixing to each holder by inserting plate-shaped wall elements, such as a side wall, a rear wall and/or a front panel. The depth of the groove-shaped receptacles can be the same or different, for example, a deeper groove-shaped receptacle can be formed for the side walls, which extends at least partially adjacent to the running rail.
- For an effective manufacture, the holders can be manufactured as moulded parts made of plastic so that they can be easily mounted on the movable track and then form a support for the base. To fix a holder, a plug can be provided which is inserted into a hollow chamber on the running rail. The plug can be positively or non-positively fixed to the rail. Alternatively or additionally, a hook can protrude from each track to fix one of the holders. The holder can then be placed on the hook in order to be fixed in a clamping or form-fitting manner.
- In a preferred embodiment, the pushing device comprises two side walls, a rear wall and a front panel, which surround the floor in a frame-like manner. A rear end of a side wall and an end of a rear wall can be fixed to each rear holder, while an end of a front panel and a front end of the side wall are fixed to each front holder. The side walls, the rear wall and/or the front panel can be made of a plate-shaped material. Various materials are conceivable, such as transparent or non-transparent plastic, glass, wood or composite materials, but also bent aluminium or steel sheet. Different materials or colours can also be combined in a pushing element. It is also easy to equip the drawer unit with light, for example an LED strip, lettering or decorations. In this way, a very individual push element can be realised. A box-shaped drawer element with transparent surface elements is particularly suitable for household appliances, such as refrigerators, as the contents of the drawer can then be viewed from the outside. An arrangement of corresponding drawer elements in a piece of furniture, also behind a pull-out with a high front panel, as an internal drawer or behind hinged doors can also be a preferred application.
- In order to increase stability when forming a drawer, the side walls can be connected to the front panel by means of an upper corner element which is pushed on from above so that an upper end of the side wall and an upper end of the front panel are held in an angular groove-shaped receptacle of the corner element. Similarly, a corner element can also be fixed in the rear area between the rear panel and a side panel by plugging it on, which fixes the position of the rear panel to the side panel. This upper corner element can further have a surface element extending to the lower holder, which preferably covers the gap between the front and the side wall, or the rear and side wall.
- In a further embodiment of the pushing device, a projection is formed on the front or rear holder, which can be brought into engagement with a movable driver of, for example, a self-closing device or a damper or an ejector or a combination thereof. Thus, in addition to forming a support for the floor and a possible support for a side wall, a rear wall and/or a front panel, a holder can also be used to couple the movable running rail with a stationary self-closing device or damper or, for example, to bias or decelerate or lock the movable running rail in the closing direction shortly before reaching the closed position.
- In a method of assembling a pushing device according to the invention, a front holder is first mounted on a front end of a movable track of a first pull-out guide and a rear holder is mounted on the rear end of the track of the first pull-out guide. Further, a front holder and a rear holder are mounted to the movable track of a second drawer runner. The two pull-out guides are then fixed to a body of a piece of furniture or household appliance, and then a base is placed on the four holders at the mounted pull-out guides. The base is then supported on the four holders and can be covered with objects.
- To form a drawer, a side panel can then be inserted into an upwardly open, groove-shaped receptacle on each holder, and in addition a rear wall or a front panel can be inserted into a further upwardly open receptacle. This frame-shaped structure with the front panel, the two side panels and the rear wall can then be secured by corner elements, each of which is fitted in a corner area from above onto a side wall and a rear wall or front panel. This allows a drawer to be made with only a few components.
- In a preferred embodiment, the two runners can be locked in an extended position to allow simplified assembly of the base, side walls, front and rear walls.
- The invention is explained in more detail below by means of several embodiments with reference to the accompanying drawings. They show:

Thefront holder 9′ comprises a groove-shapedreceptacle 19 for fixing a front panel and a further groove-shapedreceptacle 17 aligned at an angle thereto for inserting aside wall 12. Furthermore, ahorizontal support 16′ is provided on theholder 9′ for supporting a corner region of the base 11′. Thesupport 16′ is arranged slightly lower, so that the walls of the groove-shapedreceptacles support 16′ and thus limit a displacement of the base 11′ in the horizontal plane. Thefront holder 9′ further comprises a downwardly projectingfastening part 50 on which fastening means 51 are mounted to fix theholder 9′ to the runningrail 7. - In the embodiment example shown, the
holders holders movable running rail 7 can be varied. For example, thefront holder 9 can also be fixed to the runningrail 7 by means of ahook 70 or therear holder 10 is mounted by means of a plug which is inserted into a hollow chamber of the runningrail 7. In addition, the design of the bottom 11 and 11′ can be varied depending on which objects are to be stored on thepush device 4. - The supports 16 and 16′ on the
holders rail 7 as well as on an inner side of the runningrail 7 and below the upper side. -
