<p>Wall brackets, one above another, hold and guide an appliance which has a carrier parallel to the wall. There is a guide rail sliding in the brackets and a hoist to enable the appliance to climb up a wall. The guide rail (6) has a device (23) at the top, for swivelling mounting on a wall bracket (1). It also has a support bracket (19), connectable to a wall bracket, to support the bottom of the hoist (12, 13). At the bottom of the carrier (10) there is a support element (17), adjustable lengthways at right angles to the wall (W). Construction and manipulation are simplified and the mechanism can be used on a wall curving out of a vertical line.</p> |
