The present disclosure is directed generally to hand tools and in particular to a hand roller providing for the application of enhanced roller pressure in an ergonomic manner.
The present disclosure is directed to a hand roller for application of pressure to a surface. The hand roller comprises a handle rigidly secured to a roller frame. A roller cylinder is rotatably secured to the roller frame. The roller frame features an upper pressure surface having an ergonomic shape to facilitate the application of enhanced pressure on the roller cylinder.
According to certain embodiments the upper pressure surface may have at least one planar portion, at least one curved portion, or both. The upper pressure surface may have multiple curved portions. In one embodiment, the upper pressure surface has a planar surface and two curved surfaces. The first and second curved portions of the upper pressure surface may be disposed on opposite sides of the planar portion.
In certain embodiments, the handle has a principal axis and the planar portion of the upper pressure surface is disposed at an angle to the principal axis of the handle, or to a plane parallel to both the principal axis of the handle and the axis of rotation of the roller cylinder. This angle may have a value between 0 and 45 degrees. In certain embodiments, the angle is between 20 and 30 degrees or more specifically between 22 and 26 degrees. In one embodiment, the angle is approximately 24 degrees.
The foregoing disclosure will be best understood, and the advantages thereof made most clearly apparent, when consideration is given to the following detailed description in combination with the drawing figures presented. The detailed description makes reference to the following drawings:
The following detailed description provides certain specific embodiments of the subject matter disclosed herein. Although each embodiment represents a single combination of elements, the subject matter disclosed herein should be understood to include sub-combinations of the disclosed elements. Thus, if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also intended to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed herein.
Roller cylinder 16 revolves around axis of rotation R. Handle 102 has a principal dimension, with axis A running generally lengthwise along the center of the principal dimension. In the embodiment shown in
Handle 102 may be constructed from a variety of suitable materials, including polymers, wood, metals or composite materials known to be suitable for the construction of handles. Roller frame 104 may be constructed from any suitable material providing sufficient strength and durability, but the embodiment described herein incorporates a roller frame 104 constructed of metal, and specifically ductile sheet steel. In a similar manner, roller cylinder 106 may be constructed from a range of materials, including rigid polymers, elastomeric polymers, metals and composites. In certain embodiments, roller cylinder 106 is constructed from an elastomeric shell disposed around a rigid core.
Along the left side of roller frame 104, left side panel 122 comprises left bend line 156 adjacent to upper pressure pad 120, front sigmoid edge 160, radius 162 about annulus 134, lower straight edge 164, rear bend line 166 adjacent to left rear panel 126 and rear edge 168. Left rear panel 126 comprises rear bend line 166 adjacent to left side panel 122, lower sigmoid edge 170, rear bend line 172 adjacent to rear tang 130, and upper sigmoid edge 174. Left rear tang 130 comprises rear bend line 172 adjacent to left rear panel 126, lower straight edge 180, rear radius 182 and upper straight edge 184.
Along the right side of roller frame 104, right side panel 124 comprises right bend line 154 adjacent to upper pressure pad 120, front sigmoid edge 190, radius 192 about annulus 136, lower straight edge 194, rear bend line 196 adjacent to right rear panel 128 and rear edge 198. Right rear panel 128 comprises rear bend line 196 adjacent to right side panel 124, lower sigmoid edge 200, rear bend line 202 adjacent to rear tang 132, and upper sigmoid edge 204. Right rear tang 132 comprises rear bend line 202 adjacent to right rear panel 128, lower straight edge 210, rear radius 212 and upper straight edge 214.
The foregoing summary, as well as the following detailed description of certain embodiments of the present disclosure, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the disclosure, certain embodiments are shown in the drawings and described herein. It should be understood, however, that the present disclosure is not limited to the arrangements and instrumentalities shown in the attached drawings.
It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification or claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
