Definitions

• This invention relates to a household appliance comprising a height adjusting mechanism adjusting the foot heights preferably the rear foot heights from the front part that is easily attained.
• the position of the household appliance is adjusted with respect to the floor by having the screwed feet carrying the household appliances moved upwards and downwards by the user. It may be difficult or often impossible especially for the feet at the back part to be moved. Thus the back feet are moved by controlling from the front part.
• German Patent 19606460 discloses a height adjusting device for household appliance, which moves in the body and is locked by its form.
• European Patent Application 1103206 defines a height adjusting mechanism, which provides the required position by a roller.
• French Patent Application 2618208 describes a height adjusting mechanism, comprising foot attached to screws for increasing the height by means of the adjustment links.
• German Utility Model 9421684U defines a household appliance having foots which can be elevated by screws.
• United States Patent 1417639 discloses a mechanism, which elevates by worm gears.
• the object of this invention is to provide a household appliance comprising a height adjusting mechanism, which levels the foot at unreachable points by preventing the excess of the limit heights.
• the household appliance realized in order to attain above-mentioned objects of the present invention has been illustrated in the attached drawings, wherein; [010] Figure 1 is a perspective view of a household appliance.
• Figure 2 is a perspective view of a height adjusting mechanism.
• Figure 3 is an exploded view of a height adjusting mechanism.
• Figure 4 is a top perspective view of the top position of the ring gear wherein a foot, which comprises a moving ring gear and to which a foot stopper ramp is attached.
• Figure 5 is a side perspective view of the position of the ring gear on the foot gear wherein a foot which comprises a moving ring gear and to which a foot stopper ramp is attached.
• Figure 6 is a bottom perspective view of the top position of the ring gear wherein a foot, which comprises a moving ring gear and to which a foot stopper ramp is attached.
• the household appliance ( 16) preferably a built-in household appliance which is the subject of the invention comprises a button (15) providing the adjustment of height, a height adjusting mechanism (7) providing the adjustment of the foot heights preferably the rear foot heights from the front part and an extension shaft (6) transferring the command from the button (15) to the height adjusting mechanism.
• Height adjusting mechanism (7) comprises a body (1) protecting itself and its parts, a foot (2) which carries and levels the household appliance (16), an worm gear (4) attached to the extension shaft (6) which moves the foot (2), a ring gear (5) which transfers the level the user uses as worm gear (4) to the foot (2), a foot stopper (3) on the foot (2) which prevents the elevation of the household appliance (16) over than the highest possible level without preventing its being lowered.
• the body (1) comprises a foot housing (8) into which the foot (2) is mounted on the body (1), more than one body gear tooth (10) inside the foot housing (8) and a worm gear housing (17) where the worm gear (4) is bedded.
• the foot (2) comprises more than one foot gear tooth (11) which is activated by moving among the body gear teeth (10), one or more cam housing (12) on the foot gear tooth (11), a fixing surface (9) for being fixed onto the floor below and a stopper housing (18) in which the foot stopper (3) is placed.
• the extension shaft (6) comprises one or more worm gear fixation housings (23) for being fixed to the height adjusting mechanism (7) to transfer the motion current on the extension shaft (6).
• the worm gear (4) comprises more than one gear pitch (27) for moving the foot (2) in the same number with the rotation amount when it is rotated around its own axis by the extension shaft (6), one bearing support (24) on both sides of the gear pitches for moving above, one or more worm gear fixation snap (22) close to the extension shaft (6) from the bearing supports (24) for attaching with the extension shaft (6) passing through the worm gear fixation housing (23) and one or more fixation ring (21) for preventing the removal of the worm gear fixation snap (22).
• Ring gear (5) comprises more than one ring gear (25) for transferring the drive force from the worm gear (4) to the foot (2), one or more cam (13) for moving on the foot gear tooth (11) sliding in the cam housing (12) and a support extension (26) for fixing into the foot housing (8).
• the body (1) comprises an assembly housing (28) for easy pass of the cam (13) on the top front surface of the foot housing (8) and easy mounting of the ring gear (5) and one or more holders (29) for holding the ring gear (5) on the foot housing (8) following the assembly.
• the foot stopper (3) comprises more than one foot stopper ramp (14) for preventing the excessive elevation of the foot (2) and returning to the prior gear pitch and one or more stopper fixation claw (19) for fixing into the stopper housing (18).
• the foot (2) comprises one or more stopper fixation housing (20) for providing its pass and fixation into the fixation claw (19).
• height adjusting mechanism (7) is grouped and fixed to the household appliance (16).
• the ring gear (5) is firstly fixed on the foot housing (8) in the mechanism body (1) in a way to be placed under the holder (29) and the cams (13) in the ring gear (5) are attached by rotating in a way to pass through the cam housing (12).
• the foot stopper (3) is fixed to the foot (2) and after the worm gear (4) is fixed on the worm gear housing (1 ) in the body (1), the extension shaft (6) is attached to the worm gear
• the height adjusting mechanisms (7) where there are feet wanted to be moved together are controlled by the same button (7) and the same extension shaft (6).
