Description

MECHANISM FOR ADJUSTING THE HEIGHT OF DISH BASKETS
The present invention is related to a mechanism for adjusting the height of the dish baskets in the dishwashing machine in order to accomplish the adjustment of the upper basket height vertically, when it is loaded, without requiring the basket to be taken out of the support system.
The dishwashing machines consist of a rail roller assembly, a guiderail moving betwen the rail roller assembly, rollers in the rails that are connected to the upper basket and a rail cap serving as a stopper to prevent the upper basket from getting off the rail during usage. When modification in the height of the basket is desired, the user opens the rail cap and takes the dish basket off the rail, locates the other row of rollers of the upper basket on the rail and closes the rail cap. It is quite difficult to perform this procedure when the basket is loaded with dishes; it can be made more easily after the basket is unloaded.
In the systems disclosed in German Patents Nos: DE 3004110 and DE 3025311, a basket height adjusment is made by using a quite costly mechanism that is mounted on both sides of the basket, which does not require the opening of the rail cap, when the basket is loaded.
The object of the present invention is to provide the height adjustment of the upper basket in a dishwashing machine by using a single mechanism on both sides of the basket without taking the upper basket out of the machine.
The dish basket height adjusting mechanism realised in order to attain the object of the present invention is illustrated in the attached drawings, wherein:
Figure 1 - is the exploded view of the dish basket height adjusting mechanism,
Figure 2a - is the bottom view of the mechanism in closed form, Figure 2b - is the bottom view of the locking section of the mechanism in closed form, Figure 3a - is the top view of the mechanism in closed form, Figure 3b - is the top view of the locking button section of the mechanism in closed form,

The basket height adjusting mechanism consists of the straight arm (1), formed arm (2), lock (3), spring (5), rollers (10), locking button (6) and basket connection shafts (22).
At one end of the straight arm (1) and at one end of the formed arm (2), there is a hollow roller shaft (19) with preferably right-angled projections. The rollers (10) are mounted on the shaft (19) with straight arm (1) and the formed arm (2) in such a manner that they move along the guide rails on the lateral walls of the dishwashing machine.
On the other ends of the straight (1) and formed (2) arms, there is an oval shaped basket connection shaft bearing (21) in which the basket connection shaft (22) is mounted to provide the connection between the basket (11) and the mechanism. At the bottom of the structure formed so that the basket connection shaft (22) is mounted to the basket connection shaft bearing (21), basket connection wire bearing (23) provided for the passage of the basket wire (13) and basket connection shaft claws (25) are arranged.
L-shaped hooks (12), formed as the ones on the straight (1) and formed (2) arms, facing to each other are provided to be hung to the basket, in order to avoid the torsion of the arms (1 and 2) due to excessive load.
The cylindrical bearing (15) on the formed arm (2) is mounted on the straight arm movement bearing (17) which is at the center of the straight arm. The rollers (10) are mounted on the roller shafts (19). After the spring (5) is mounted on the spring bearing (16) at the center of the formed arm (2), the locking button (6) and the lock (3) are interlocked keeping the spring (5) at the middle. A fixing end locking form (9) is formed on the surfaces of the locking button (6) and the locking spring bearing (26) as recesses and projections engaging to each other. Straight arm connection bearing (14), wherein the locking wedge (4) can be inserted, are provided around the cylindrical bearing (15) on the formed arm (2) (Figure 2b). The spring (5), compressed between the lock (3) and the locking button (6), gains initial tension and applies force in order to prevent the release of the lock (3) from the straight arm connection bearing (14). The assembly of the mechanism is completed by fitting the basket connection shaft (22) into the basket connection shaft bearing (21) that is at the end of the straight (1) and formed arm (2). The mechanism is mounted to the basket (11) by means of the basket connection shaft (22). The L-hook (12) is hung on the basket wire.
When the basket (11) is at the lower position, in this position the mechanism is closed, the locking wedge (4) is not fitted into the straight arm connection bearing (14). The spring (5) applies force to the straight arm connection bearing
(14), in the direction of fitting (Fig. 2a and 2b). The mechanism arms (1 and 2) start to open while the basket (11) is raised upwards. The formed arm connection latch (18) pushes and rotates the locking wedge (4). When the locking wedge (4) comes over the straight arm connection bearing (14), due to the spring (5) pulling in the locking wedge (4), it is fitted in the straight arm connection bearing (14) (Figures 4a and 4b). So the locking button (6) connected to the locking wedge (4) moves forward (Figures 5a and 5b).
When the basket (11) is desired to be at a lower position, the locking button
(6) is pressed, the locking wedge (4) releases the straight arm connection bearing (14), and the mechanism closes due to the weight of the basket (11). During the vertical movement of the mechanism, the torsion of the mechanism attached to the basket wires is prevented by the L-hooks (12).
The basket adjusting mechanism is attachable on the basket connection wire (13) provided on both sides of the basket (11). The mechanism, attached to the right side of the basket (11) can be rotated and attached to its left side. Thus, a single basket adjusting mechanism can be used without right or left differentiation.
In the preferred embodiment, the roller moving along the guide rails of the dishwashing machine is decided to be two units and the mechanism that is fixed on the basket. It is possible to provide roller to all end parts of the straight and formed arms of the mechanism and to operate the mechanism by means of the said switch movement, which is the subject of the invention.
