  • a coil spring 24 is described but other springs may be used, including leaf springs, bows, butterfly spring, a biasing device, and other elastic objects used to store mechanical potential energy.
  • a motor may be used to extend or retract the blade end 20. Incremental translation or advancement may be achieved using suitable mechanisms such as cranks, pulleys, chain and sprocket, ratchets, wedges, endless conveyors, and other force transfer devices.
  • Devices 10 may be connected between adjacent tiles before positioning the tiles on a mortar bed 58.
  • a shaft tensioner may be provided between shaft 12 and pressure plate 16, similar to a bolt tensioner.
  • Passage 25 may extend part way into pressure plate 16. Passage 25 may comprise a slot in pressure plate 16. Up, down, top, base, and other relative words are not intended to be limited to absolute dimensions defined with respect to the direction of gravitational acceleration on the earth. In some cases the tiles 21 may be located on a wall, ceiling, or other non -horizontal surface.
  • Description of a component being located at an end includes locating the component at or near the end.
  • the blades 14 may have a suitable propeller shape for cutting through and displacing mortar.
  • Device 10 may be used in suitable applications such as tiling or paving applications.
  • Mortar comprises a workable paste used to bind building components together, and includes adhesive, thinset, concrete, grout and other cementitious compositions.
  • a screwdriver connection may be provided to translate the pressure plate 16 or handle 26 to clamp the tiles 21 together. In some cases no spring is provided, for example if spring 24 is removed from the embodiment of Fig. 1, and the handle 26 incrementally translated to clamp the tiles 21 between pressure plate 16 and blades 14.
  • a bushing surface (not shown) may be provided between the necks 37 and 39 to prevent handle 26 and spool 30 from rotationally locking via friction.
  • Blades 14 may extend along a common blade axis 85 or may have parallel but relatively displaced axes, in case the position of each blade 14 is different to compensate for different tile thicknesses. Blades 14 may be non-linear in shape, such as if blades 14 are curved upward and resilient to accommodate different tile thicknesses. Pressure plate 16 may have a tile contacting surface, for example comprising resilient or flexible material such as rubber or foam. The tile contacting surface may have a planar surface. The blades 14 and base end 20 may form a three dimensional T-shape. A width of the blade end 20 along an axis perpendicular to the shaft axis 63 and the blade axis 85 may be equal to or less than a width of tile contacting portion 96.
  • Plates 16 and 27 may be disc-shaped.
  • a cross section of the shaft 12 perpendicular to the shaft axis 63 across the torque transfer portion 49 may have a polygonal shape as shown in Fig. 11 A.
  • the blades 14 may be integrally connected with the base end 20. Blades 14 may have lateral passages, slots or apertures, to permit the passage of mortar during rotation.
  • the shaft 12 may have a circular, square, or other suitable shape in cross section. As shown in Figs. 6-8 the blades 14 may have blunt terminal ends.
  • the blades may have the shape of and may be hooks, such as is shown for example with the blades 14 each having rectangular cross-sections profiles drawn in a plane defined by both the blade axis and shaft axis, the plane defined by the page in Figs. 6-8.
  • the tile alignment device may be entirely hand-operated without requiring the use of additional tools such as wrenches, pliers, or hammers.

Abstract

L'invention concerne un dispositif d'alignement de carreaux qui comprend : un arbre ayant une extrémité de poignée et une extrémité de lamelle ; des lamelles opposées s'étendant latéralement depuis l'arbre au niveau de l'extrémité de lamelle ; et une plaque de pression montée sur l'arbre pour définir des évidements de réception de carreau respectifs entre la plaque de pression et les lamelles opposées respectives. Une combinaison comprend : un dispositif d'alignement de carreaux ; des carreaux adjacents fixés respectivement dans un évidement respectif des évidements de réception de carreau, dans lesquels des faces externes des carreaux adjacents viennent en contact avec la plaque de pression et qui sont de niveau les unes par rapport aux autres. Un procédé consiste à : insérer une extrémité de lamelle d'un arbre dans un espace entre des parois latérales des carreaux adjacents, l'extrémité de lamelle ayant des lamelles opposées s'étendant latéralement à partir de l'arbre ; accrocher les lamelles opposées sous les carreaux adjacents ; et serrer les carreaux adjacents entre les lamelles opposées et une plaque de pression montée sur l'arbre.
