Hand held screed raking device for applying paving material to a surface

Abstract

A hand held screed raking device having a longitudinally extending screed head, arced dozer front face, screed back, and tubular rake handle or rake grip handle. An underside shoe secures against the longitudinally extending screed head, connecting to a longitudinal bottom trailing surface, having a smooth, or textured bottom surface with repetitive or variable form and different forms of textured bottom surfaces. The textured bottom surface may dampen in amplitude, and be oriented with respect to application material applying direction. The user dozes pushing or pulling the device over a surface, loading application material along the arced dozer front face applying it on the surface.

Description

FIELD OF THE INVENTION[0001]This patent disclosure relates to a hand held screed raking device, or screed rake, for applying material to a surface.BACKGROUND OF THE INVENTION[0002]Hand tools having variated working surfaces for shaping and spreading concrete, glue, or other viscous materials are common in the industry. However, there has been a recognized need, such as in the road paving industry, for providing screed plates with differing textures to the underside screed or working surface. These application, viscous, materials include various substances, such as grout for tiling, asphalt for a road surface, or landscaping material for a lawn. A need has been recognized in the industry for hand tools, such as a rake or trowel device that could lay material on a smoother grade without segregating it into constituent sizes, in a comfortable and an easy to operate design.[0003]Additionally, it has been recognized that a variable or repetitive, wave-like pattern or other textured patte...

Benefits of technology

[0013]The underside shoe freely, securely and removably attaches against the angular bottom plate by an at least one shoe attaching means, allowing the underside shoe to be removable. In another alternative embodiment, a screed head cooperating heel securing notch may be located immediately and vertically above a shoe back end, removably and securely houses a removable shoe heel wear protective surface strip.

[0016]The textured bottom surface enables larger aggregates of application material to be moved or travel more easily underneath the hand held screed raking device and intermix in a homogeneous manner to discourage any segregation of particle size of the application material on the surface. The tubular rake handle, as well as the rake grip handle, in an alternative embodiment, are formed from material which is less thermally conductive or non-conductive than in prior art.

[0018]The hand held screed raking device is a hand held tool for spreading, screeding, moving or applying application material, including viscous material such as asphalt, concrete, grout, glue, or landscape materials such as dirt; utilizing either the smooth bottom surface, the group of textured bottom surface forms or other textured bottom surface forms, to help discourage application material segregation when the user moves and applies the application material to the surface.

[0019]The longitudinal bottom trailing surface is operated similar to any hand held rake or trowel with the added control in the present invention of pitching the screed surface angle of attack, defined by the upwardly angled leading surface, to control application material grade during use in the applying direction. The arced dozer front face more evenly distributes the application material being laid or spread out by the user in the applying direction while leaving a better, less segregated application material on the surface, by allowing the “floating screed”, the application material, to be controlled by pitching the angle of attack of the longitudinal bottom trailing surface. By adjusting the vertical angle of attack, the user can make smooth grade adjustments while spreading, in the applying direction, the application material being raked or applied. As the application material travels in the applying direction under the longitudinal bottom trailing surface, it is compacted, leaving a better finish on the surface without the segregation of portions of the application material. By using a unique variable wave design, such as a wave form bottom surface, the application material, such as aggregate, may be evenly spread and compacted on the surface in a homogenous fashion, and allows larger aggregates to move more easily under the longitudinally attached bottom trailing surface, further discouraging segregation by compacting the larger aggregate being laid into the surface.

[0020]In alternative embodiments of the present invention, the longitudinally extending screed head may be comprised of one or more of the following: aluminum, plastic, or other durable and lightweight material preventing hotter application material from sticking to the hand held screed raking device as easily as with commonly known screed raking devices, and preventing wetter application material from freezing and sticking.

[0021]Another advantage is the ease of use allowing different handle pitch options for taller users with the hand held screed raking device. Use of the hand held screed raking device is not limited to or specific to any one industry, and may be used in the paving industry, concrete industry, construction industry, landscaping industry, as well as other industries where the use of such hand held equipment for applying application material is required, allowing a user to more easily obtain an acceptable grade of application material without the segregation problems that are inherent to current rakes found in different industries, and spread a multitude of application materials, including, but not limited to, aggregates and aggregate mixtures, soils, landscaping materials; and in a number of applications, such as for distributing glue or grout, patching asphalt, for preparing subgrade surfaces, and for tiling or finishing surfaces, and other surface application activities.

Problems solved by technology

Because these metals have a high thermal conductivity, the rakes cool rapidly while raking the hot asphalt making the asphalt stick easier to the rake and the application of such material to a surface very difficult.
