Title:
WORKTOP FASTENER
Document Type and Number:
WIPO Patent Application WO/2000/049914
Kind Code:
A1
Abstract:
The worktop fastener (1) consists of a retaining pim (6), a locking system comprising a catch lever (3) and a catch (2), a clamping plate (4) and a load obstruction (5). By the vertical forces aplied on the worktop (8) (upwards and downwards), the retaining pins (6) on the worktop fasteners (1) start to function and restrict the free movement in the vertical direction, of the worktop (8); whereas the horizontal forces applied on the worktop (8) (forwards and backwards) the worktop fastener (1) starts to function and restricts the horizontal free movement of the worktop (8). During assemblage, the vertical load obstruction (5) on the worktop fastener (1) is inserted into the cavity on the upper framing part (7). This forms an obstruction for the potential vertical forces on the catch (2) during vertical loadings.

Description:
WORKTOP FASTENER The present invention is related to dismounting and mounting the worktop placed on electrical domestic appliances in a simple and easy manner without using screws, when it is required to dismount or mount the said worktop.

The fact that screws are used for the mounting of the said worktop on the electrical appliances creates difficulties during the mounting process. In some well-known applications, the said process is realised without using screws but this requires the incorporation of another part in addition to the worktop and the fasteners. In another application, the worktop is positioned at the farbackside of the frame due to the reason that the catch click socket is positioned at the same place on the machine. The said part is placed at a position that can be seen when looked from the side. Furthermore, as there is not a smooth touching surface on this part in order to release the catch click, the manual command of the catch click system is difficult from the ergonomical point of view. Besides, the resilience surface (plane) of the catch has been positioned parallel to the chipwood worktopsurface and locking has been provided at two points. A distance is left between the lower catch and the resilience plane, sufficient to allow the formation of moment; and this permits the rotation of the click under load and a displacement that moves the worktop. The assembly gap left for an easy fitting of the click, causes the movement of the worktop within the limits of the said gap when moved forwards/backwards.

The object of the present invention is to provide the easy interlocking as well as dismounting of worktop to the welded, upper framing part situated on the top of the bodies of the electrical domestic appliances, without using screws.

The worktop fastener realised to achieve the above mentioned object of the present invention is illustrated in the drawings, wherein:

Figure 1-shows the perspective bottom view of the worktop fastener.

Figure 2-shows the perspective top view of the worktop surface fastener Figure 3-is the perspective cross sectional view taken along AA in Fig 2.

Figure 4-is the side view of the position of the worktop surface fastener after it is adhered on the worktop and before it is mounted into the pin and catch socket on the upper framing.

Figure 5-is the perspective three dimensional bottom view of the worktop surface fastener taken along its upper framing cross section after it is adhered on the worktop and mounted into the pim and catch socket on the upper framing..

Figure 6-is the cross section taken along BB in Fig. 2, of the worktop fastener.

Figure 7-is the cross section taken along CC in Fig. 2, of the worktop fastener.

The components shown in the drawings are numerated as follows: (1) Worktop fastener (2) Lock (catch) (3) Catch lever (4) Clamping plate (5) Load obstruction (6) Retaining pin (7) Upper framing part (8) Worktop (9) Resilience plane (10) Rotational axis The worktop fastener (1) consists of a retaining pin (6) that provides fastening onto the upper framing part (7) by being slide in a horizontal direction ;

a locking system formed by the catch lever (3) and the catch (2) at separate planes, positioned with some distance between each other and parallel to the worktop surface but with the possibility of resilience on a plane that is vertical to the said worktop (8) chipwood surface; clamping plate (4) situated at the same plane and the vertical load obstruction (5).

More than one worktop fastener (1) are used in the worktop (8) assembly.

The worktop fastener is attached to the worktop (8). When the worktop (8) is desired to be mounted on the machine, the retaining pins (6) present on the worktop fastener (1) are insured into the pin sockets provided on the upper framing parts (7) and slided on a plane that is parallel to the ground. Thus, the worktop (8) is pushed towards the front face of the machine, until the plane on which the clamping plate (4) and the vertical load obstruction (5), rests on the external lateral surface of the upper framing part (7). During this movement, the lower end of the catch (2) also contacts with the upper framing part (7) and turns downwards around the resilience plane (9) that is vertical to the chipwood, and raises up after the relief of the pressure by entering into the upper framing part (7) recess and thus fixates the worktop fastener (4), and thus the work top plate (8) to the upper framing part (7).

Furthermore as the clamping plate (4) shall continuously be in contact with the upper framing part (7) surface, by applying a force in the opposite direction to the assembly direction, it shall thus ensure a full fitting of the catch (2) onto the upper framing part (7) without allowing the formation of any assemblage gap. The mounting of the worktop (8) is thus completed.

By the vertical forces applied to the worktop (8) (upwards and downwards), the retaining pins (6) on the worktop fasteners (1) restrict the free movement in the vertical direction, of the worktop (8); whereas, in case of the horizontal forces applied on the worktop (8) (forwards and backwards) the

worktop fastener (1) restricts the horizontal free movement of the worktop (8). During assemblage, the vertical load obstruction (5) on the worktop fastener (19) is inserted into the cavity on the upper framing part (7). This forms an obstruction for the potential vertical forces on the catch (2) during vertical loadings. At the surfaces that are parallel to this ground, the upper framing part (7) and its contact surface are beyond the catch (2).

The rotational axis (10) of the catch (2) on the resilience plane (9) that is vertical to the chipwoo has been aligned with the catch (2) (i. e. brought to the level of the catch); this level indicates the horizontal plane passing through the region where the catch (2) establisher contact with the upper framing part (7) inner surface the worktop (8) is pulled backwards upon horizontal loadings. The fact that the rotational axis (10) is on the same plane as the horizontal force applied on the catch (2), minimizer the formation of a moment that may permit the rotation of the catch (2). The catch (2) shall minimize the movements of the welded worktop (8) in case the worktop (8) is pushed backwards after the assemblage.

The worktop (8) is required to be dismounted for such cases as when the dishwasher has to undergo a maintenance or repair service or when the dishwasher is to be installed under work bench at the kitchen. The catch (2) of the worktop fastener placed at the inner surface of the upper framing part (7) after assemblage, has to be released for the dismounting of the worktop (8).

The moving and release of the catch (2) from the lock socket on the upper framing part (7) is significantly facilitated due to the catch lever (3) with an ergonomic touching surface and distance.

By pressing the catch lever (79) upwards, the downward motion of the catch (2) is provided and while it is at this position, the worktop (8) is pulled backward in the horizontal direction. The worktop (8), thus released from the

catch is slided to the position where the retaining pins (6) come to the free position and is removed from the top of the dishwashing machine.

By this system, the possibility of manual intervention by pulling the catch lever (3) backwards although the catch (2) is at the front, is provided.

Furthermore, the catch lever (3) that is vertical to the resilience plane (9) is positioned so that there is some vertical and horizontal space (distance) from the rotational axis (10) that is on the resilience plane; and moment arms have been formed on both pleases. During the upwards pushing applied on the catch lever (3), the catch (2) shall rotate and be released by applying very little force.
