Abstract

Height-adjustable roller for a sliding door with an attachable to the sliding axle axle body and a rotatably mounted thereon race (3), characterized in that the axle body (2) has an outer element (22) in which an eccentric inner element (31) is received against in that the outer element (22) is rotatable, wherein the inner element (31) can be fastened to the sliding door, and that an adjusting device (7) is provided for adjusting the rotation of the outer element (22) relative to the inner element (31).

Description

The The invention relates to a height-adjustable roller for sliding doors, in particular for sliding doors from Shower stalls. In shower cubicles, the shower tray is often tilted a little built-in to allow the water to settle in a specific area of the basin can collect. This requires that provided on the pool catwalk for the sliding door then also inclined. The shower cubicle itself allows this inclination not for optical reasons have; Consequently, there must be a height compensation between the rollers of the sliding door be created so that the sliding door is exactly vertical. This can happen once by the receiving holes of the Sliding door, in which the casters are fixed, even enough clearance own so that an adjustment can be made. For larger adjustment ranges has already been provided, the roller to an eccentric to attach, so by turning the eccentric the height of the axis the caster changed can be.

These Devices have the disadvantage that for adjusting the attachment the roller on the sliding door solved must be, which makes the adjustment and adjustment difficult. Since the roller is held by clamping action on the sliding door, works constantly the weight of the sliding door, so that the clamp connection over time the originally preset Leave position and the roller slides down. at Adjusting the mechanisms with eccentrics is still the reinforcing leverage of the eccentric so that the advantage of easier adjustment by Twisting the eccentric lifted by this disadvantage again becomes.

task The invention accordingly is to design a caster in such a way that that the height the roller can be adjusted easily and accurately without that in the course of operation due to the weight of the disc, the height adjustment lost again.

These Task is according to the invention solved with a roller, which has the features listed in claim 1. Further, advantageous embodiments of the invention will become apparent from the dependent claims.

Of the Advantage of the embodiment according to the invention is that the jamming of the roller to the disc and the height adjustment of the Roller are decoupled from each other by means of the eccentric, d. H. the height adjustment with the eccentric leaves make without the jamming or attachment of the roller at the sliding door solved must become.

The The invention will now be described with reference to the embodiment shown in FIGS described and closer explained.

The 1 shows an exploded view of the roller according to the invention, the 2 shows the roller in the assembled state with a key for the adjustment.

According to the exploded view of 1 the roller according to the invention has a tread ( 3 ) on a bearing ring ( 21 ) is rotatably mounted. In this bearing ring ( 21 ) is an outer element ( 22 ), in which eccentrically an inner element ( 31 ) is arranged, which can be rotated against each other. The interior element ( 31 ) has a central bore ( 32 ) into which a blocking element ( 33 ) of the inner element with its shaft ( 34 ) is used. The blocking element ( 33 ) has a flange ( 35 ) with a toothed segment ( 36 ). At its end facing the sliding door has the flange ( 36 ) of the blocking element a recess ( 37 ), with which he also against rotation through the bore ( 32 ) into a foot ( 6 ) intervenes. The foot ( 6 ) has at its lower end a flange ( 61 ) for reaching under the lower edge ( 19 ) the sliding door ( 9 ).

The bearing ring ( 21 ) forms together with the outer element ( 22 ) the axle body of the roller. Between the inner element ( 31 ) and the outer element ( 22 ) is in a recess a tooth jaw ( 41 ) whose teeth are complementary and fit to the toothed segment ( 36 ) is trained. The tooth cheek ( 41 ) is in this recess in the axial direction of the sliding door between a position in which they in the toothed segment ( 36 ) engages, and a depressed position in which it is led out of the engaged position, displaceable. She is by a spring ( 42 ) so that it is pressed into the locking position. For attachment to the sliding door is a bolt ( 8th ) passing through a hole ( 91 ) in the sliding door through a perforated disc ( 10 ) is protected by the foot ( 6 ) and the bearing ring ( 21 ) into the threaded hole ( 38 ) of the blocking element ( 33 ) enters and is screwed with her. Will the tooth jaw ( 41 ) pushes it out of the sector of the tooth ( 36 ) of the blocking element ( 33 ) out. The outer element ( 22 ) can now relative to the inner element ( 31 ) are twisted. Because of the eccentricity thereby changes the position of the axis of rotation of the tread ( 3 ) relative to that by the bolt ( 8th ) and the locking element screwed therewith ( 33 ), so that thereby the distance of the axis of rotation of the tread relative to the lower edge ( 19 ) the sliding door ( 9 ) can be adjusted. The adjusting device ( 7 ) is thus by the outer element ( 22 ), the tooth-cheek ( 41 ) and with the blocking element ( 33 ) provided inner element ( 31 ge forms. The blocking element ( 33 ) has on its front side small recesses ( 39 ) into which a cover plate ( 12 ) is inserted with corresponding, not visible in the drawing pin and held by clamping action.

The 2 shows the roller in the assembled state, wherein the cover ( 12 ) is removed. At the same time, the key for the adjustment process is shown. This key has two pins ( 71 ), which are cut into corresponding recesses ( 28 . 29 ) of the outer element ( 22 ) intervene. He also has a footbridge ( 73 ), which on the tooth cheek ( 41 ) and press against the action of the spring ( 42 ) from the locking position with the toothed segment ( 36 ). When turning the key, the outer element ( 22 ) against the on the sliding door by means of the blocking element ( 33 ) and the fixing screw ( 8th ) clamped interior element ( 31 ), whereby the position of the axis of rotation of the tread ( 3 ) is changed.

The key ( 7 ) suitably has a slot into which the cover plate ( 12 ), which facilitates the operation and rotation of this key.
