Abstract
A tile laying device has a main frame supported on wheels for rolling movement along a ground surface. A pendulum frame is supported on the main frame to be freely suspended from the main frame while being adjustable in height relative to the ground surface by tilting the main frame about the axis of the wheels. Suction cups on the pendulum frame allow a tile to be coupled to the tiles using vacuum pressure from a vacuum pump on the main frame. The suction cups can be shifted laterally in a direction of the pendulum axis relative to the main frame to assist in aligning a tile on the pendulum frame with a desired placement location for the tile.
Claims16
A tile laying device for laying a tile, the device comprising:
- a main frame supported on transport wheels for rolling movement along a ground surface;
- at least one suction cup supported on the main frame and being operable so as to retain the tile thereon by vacuum pressure;
- a handle supported on the main frame;
- the main frame being supported for pivotal movement relative to the transport wheels about a pivot axis of the main frame between a laying position in which said at least one suction cup is substantially at a level of the ground surface and a transport position in which said at least one suction cup is spaced above the level of the ground surface;
- the handle being pivotal with the main frame about the pivot axis and being positioned on the main frame so as to be readily gripped by hands of the operator throughout movement of the main frame between the laying position and the transport position;
- an upright pendulum frame supporting said at least one suction cup thereon at a bottom end of the pendulum frame, the pendulum frame being supported on the main frame adjacent a top end of the pendulum frame at a location spaced above said at least one suction cup for free pivotal movement of the pendulum frame relative to the main frame about a pendulum axis oriented parallel to the pivot axis of the main frame such that the suction cups are arranged to remain balanced about the pendulum axis in a level orientation as the main frame is pivoted between the laying position and the transport position;
- and
- a lateral adjustment linkage coupled to the pendulum frame such that said at least one suction cup is adjustable in a direction of the pendulum axis relative to the main frame, the lateral adjustment linkage comprises a shaft supported on the main frame along the pendulum axis upon which the pendulum frame is pivotally supported and a controllable actuator for displacing the pendulum frame laterally in the direction of the pendulum axis relative to the shaft.
A tile laying device for laying a tile, the device comprising:
- a main frame supported on transport wheels for rolling movement along a ground surface;
- a shaft horizontally supported on the main frame so as to be adjustable in height relative to the ground surface;
- a pendulum frame pivotally supported on the shaft for free pivotal movement of the pendulum frame relative to the main frame about a pendulum axis of the shaft;
- at least one suction cup supported on the pendulum frame and being operable so as to retain the tile thereon by vacuum pressure;
- and
- a lateral adjustment linkage coupled to the pendulum frame such that said at least one suction cup is adjustable in a direction of the pendulum axis relative to the main frame, the lateral adjustment linkage comprising a controllable actuator which is actuable to displace the pendulum frame laterally in the direction of the pendulum axis relative to the shaft in either one of two opposing lateral directions along the shaft.
