The lower end of the long handle is articulated on the trowel body through a spheric hinge. The long handle is designed so that users can level and trowel concrete ground while standing. The spheric hinge is designed so that the long handle can rotate by 360 degrees around an axis. When the utility model, users are just required to pull and push the trowel to and fro, and cement mortar can be applied quickly; the work efficiency is improved by a plurality of times. In order to prevent the trowel fringe from scratching the concrete surface while the trowel is pushed and pulled, the circumferential sides of the trowel body are designed to be retrousse; the push and pull resistance is reduced. The utility model has simple structure, is usable, reduces the labour intensity, saves time, saves labour, and improves the work efficiency. The utility model is in particular applicable for towelling large concrete surface.
United States patent application US 5 067 761 (BLOWERS) discloses a masonry hawk device for holding a supply of mortar or the like comprising a platen on top of which mortar is to be held with handle means extending down from the bottom side thereof for holding the device with one hand while working with an applicator such as a trowel in the other; said platen having front and rear edges and right and left side edges, said rear edge and one of said side edges being substantially bounded by upwardly extending walls, said walls intersecting and being joined at a rear corner of the platen to form an unbroken retaining wall along said rear edge and one side edge, a short upwardly extending side wall extending from said rear wall along a minor portion only of the other side edge, a major portion of said other side edge being unbounded, and said front edge being unbounded, said handle means being positioned on said platen forward of the midpoint thereof whereby the loaded hawk may be simultaneously supported by the worker's hand holding the handle and the worker's arm contacting the rear portion of the device.
European patent application EP 0 141 482 (BUCHANAN) discloses a plastering hawk preferably of polypropylene, has an elongate handle and a plate attached to one end of the handle, which plate extends in a direction transverse to the longitudinal axis of the handle. One edge portion of the plate extends away from the handle at an acute angle to the axis of the handle. In use the acute angled portion of the plate is butted against a work surface and plaster on the hawk is moved across the acutely angled portion into the work surface, thus providing a smooth transition onto the work surface.
Summary of the Invention
According to the present invention there is provided a material application device for pointing comprising: a handle and a substantially rectangular, planar plate having an upper face for receiving material, a lower face connected to the handle, a fore region for application of material and a rear region, the handle comprises an elongate member extending from a central region of the lower face of the plate so as to define a device holding axis; the handle is provided at an acute angle relative to the rear region of the plate and at an obtuse angle relative to the fore region of the plate, the plate has one lipped edge on the fore region of the plate for use in applying material to a surface and three open edges with no lip, wherein the lip extends at an obtuse angle from the plane of the plate, the handle extends in an opposed direction relative to the lipped edge, the lip is substantially parallel to the angle of deviation of the handle from the plate wherein the device is held such that the lipped edge is arranged to direct material away from the use in use and engage with a surface during pointing.
Advantageously such device belongs to the field of trowels or hawks.
The plate comprises a substantially planar sheet defining a substantially planar plane for carrying material such as plaster or mortar.
The handle intersects with the plate at an intersection to provide a depending axis of device and material holding for a user. Such intersection may be temporary and/or articulated.
The handle depends in use form this plane at an angle deviating typically at a substantially continuous angle of deviation from the orthogonal, wherein the user carries material held on the plate typically to fore of perpendicular from the user’s hand. Advantageously therefore the material on the plate is carried further forward in use, and consequently less effort is required to hold the material in an accessible location.
In this way the material is ideally substantially situated in use in front of the user’s hand in use. This is particularly advantageous with respect to vertically lower applications of material, wherein the user is not required to bend their wrist excessively in order to maintain the material plane substantially horizontal. In this way ease of application and use is improved and material is less liable to be lost during use from spillage.
In addition or the alternative less strain is put on the user’s wrist during use with regards to known hawks.
The plate advantageously includes a lip, wherein the lip acts to prevent further spillage of the material in use.
The lip is situated to fore of the plate.
Such fore lip extends at an obtuse angle from the plane of the plate, so as to allow the user to more effectively and neatly transfer material off the plate in use.
The angle at which the lip; extends from the plate is substantially equal to the angle of the holding axis. In this the device may be advantageously rested on the lip when not in use, and the user is intuitively enabled to hold the material and move it from the plate and over the lip.
The plate is substantially rectangular or rectilinear in plan. Typically, the fore lip comprises a long edge of the rectangle.
Ideally the lip extends from the plate in such a manner as to facilitate insertion of the material into elongate zones or cavities, wherein the user may push the material from the plate and over the lip in a natural and continuous action.
This facilitates usage such as for replacing pointing, wherein the material may be easily pushed into a cavity, leaving a clean edge. This is suitable for weatherstruck or bucket handle finishes.
The plate is ideally constructed of stainless steel, metal or alloy or rigid thermoplastic such as acrylonitrile butadiene styrene (abs) or polyethylene.
The handle is ideally constructed of rolled metal or alloy or rigid moulded such as acrylonitrile butadiene styrene (abs), polyethylene, Nylon (RTM), acetal or polycarbonate.
The handle may be coated or covered in a rubber or silicone finish, so as to aid in comfort in holding. In some embodiments the handle may comprise wood, for example wherein the handle includes a metallic collar.
The handle and plate are ideally bonded or welded, punched, bolted or riveted together at the intersection.
In some embodiments the handle and plate may be attached together at a screwthread intersection, for example wherein the handle has a male thread, and the intersection is formed by a female threaded collar welded, punched, bolted, riveted, bonded or otherwise permanently adhered to the plate underside.
In this way the device may be more readily transported or stored, and/or handles or plates replaced according to user preference or repair. In some embodiments the handle may comprise potential to extend, wherein the handle may be comprised of a plurality of sections in use.
In some embodiments the intersection is articulated or adjustable. In such embodiments it may be possible to secure the intersection in use or prior.
In advantageous embodiments at the intersection of the angle of axis with the plane is 60 degrees. In some embodiments the angle of the handle may vary along its length, for example wherein the handle is curved.
In some further embodiments the intersection may be articulated for example using a spherical or ball joint, or may swivel in one plane, parallel to the plate plane. Such swivelling or articulation may be controlled or locked by a lock means, for example a thumb lock.
In this way the intersection can be configured according to user preference.
