Tools have been utilized in many fields for working the surface of a material, such as sanding, polishing, grinding, and painting, among others. For example, when fabricating a structure, such as a wall or ceiling in a building, oftentimes it is useful to utilize a sanding device to smooth the surface of the structure. In the field of sanding devices, for example, several devices have been proposed.
One proposed sanding device has an elongate rectangular head. This head is designed to accommodate a standard sized elongate sheet of sand paper. This allows the tool to have an easily available supply of sand paper that can be used with the device.
However, when such a device is manipulated, the device tends to flip onto its elongate sides and can damage the surface due to its narrow configuration and the location of the attachment of the elongate handle, which is positioned high above the center of the head in relation to the device's width. For example, the corners or edges of the device can gouge the surface.
This can require filling and/or additional sanding to remove the damage. In addition, when sanding a corner area, one of the two abutting walls of the corner can be inadvertently gouged due to contact with the edge of the device.
A device has also been proposed to aid in sanding corners that utilizes an acute isosceles triangular shape. However, since the isosceles triangle has a tall narrow profile, this device also has a narrow region near the attachment to the handle and encounters the same flipping problem.
Additionally, the angles of the triangle do not match that of most corners on wall surfaces, floor, and ceiling and, therefore, a corner of the device has to be moved around the area of the corner of the surface in order to completely work such an area. This approach can lead to uneven sanding and increases the risk of poking the corner of the device into one of the adjacent walls forming the corner.
Another device utilizes a motorized rotating head that rotates rapidly to reduce the number of passes the device must take over an area. These devices are larger and more cumbersome due to the mechanical motor assembly and have a circular, non-continuous “O” shaped working surface due to the need to have access to a bolt.
The bolt is seated in the center of the “O” defined by the working surface. The bolt is used to remove the working surface from the rotational axis of the device in order to remove the sanding or other type of working material mounted to the head.
This device takes a greater level of skill to master and if used improperly, can damage the surface by dishing to create swirl marks in the surface. Further, these devices also typically allow for replacement of the working surface, but other components of the devices are typically non-replaceable. In such instances, the tool may have to be replaced or brought in for service when one of its components is worn.
Embodiments of the present disclosure include devices having a number of layers and methods of using the same. These devices may be applicable to various fields, such as those described above, among others.
For example, various embodiments of the present disclosure provide working devices that reduce the potential for scoring one or more of the abutting walls at a corner. Some embodiments reduce the propensity for tipping of a body of a device on its side.
Further, in some embodiments, the edges are designed to reduce the risk of damage to an adjacent surface. Embodiments can also provide a sanding surface for scoring an adjacent surface, e.g., a wall and/or ceiling, if desired. Also, some embodiments can include a rounded edge and/or a serrated edge which may be used to sand and/or score an adjacent working surface such as a wall and/or ceiling surface.
As discussed above, a working device can be utilized in many fields depending upon what working material is utilized. And, although the focus of the present discussion may be directed toward use as a sanding tool, the field of sanding is utilized as an example in this disclosure to illustrate some of the benefits of the various embodiments. However, the various embodiments should not be limited to the field of sanding.
In some embodiments of a tool for working on a surface, the tool includes a tool body, a base coupled to the tool body, a pad coupled to the base, and a working material coupled to the pad. In various embodiments, the tool body, the base, the pad, and/or the working material are each releasably coupled with an attachment surface. In various embodiments, at least one of the attachment surfaces includes a hook and loop fastening material. According to various embodiments, the base can include a surface defining a recessed portion to receive the tool body.
In various embodiments, the tool body can be a rigid tool body. In such embodiments, the tool body can be made of one or more metals and/or plastics, among other inflexible materials.
It should be noted that the components that will be discussed herein can be implemented independently, or in various combinations, without departing from the functionality of the various tool embodiments. For example, in various embodiments, a pad, having a releasably coupled working material thereon, can be omitted from the tool, and the working material can be releasably coupled to a different component, as will be discussed in more detail below.
The present disclosure includes a number of tool and method embodiments. In various embodiments, the tool can include a tool body. The tool body can include a top and bottom surface. The top and bottom surface can each be connected by a number of side surfaces.
In some embodiments, the tool or a portion thereof, can be motorized. For example, a vibrating or rotating mechanism can be used to move the working material.
In various embodiments, the periphery of the tool body can include a variety of shapes. In some embodiments, for example, the periphery of the tool body is a polygon. For instance, in such embodiments, the periphery of the tool body can be a rectangle, a square, a pentagon, a hexagon, and other such shapes.
In various embodiments, the tool body can receive a handle pivotably coupled to the tool body to allow an operator of the tool to manipulate the tool and various components thereof. In some embodiments, the tool body can include a concave upper surface to which a pivotally coupled elongate handle (e.g., a pole type handle with a threaded end for pivotal attachment to the tool body) can be rotatably coupled.
This concave shape can be beneficial in reducing the propensity of the tool body to flip. The reduction is accomplished, for example, by lowering the coupling point of the handle and the tool body, among other factors.
In various embodiments, the tool can include a base releasably coupled to the tool body. In some embodiments, the base can include a surface defining a recessed portion to receive the tool body.
In various embodiments, the base can be formed of a flexible material. For example, the tool can include a flexible base releasably coupled to the tool body. In such embodiments, the flexible base can include a top surface defining a recessed portion sized to accommodate the bottom surface of the tool body.
In various embodiments, the base can include a top and bottom surface and a number of side surfaces. A number of the side surfaces of the base can be at non-right angles to the bottom surface of the base. For example, as shown in
In various embodiments, the two surfaces of the base that have the rectangular shape can be the top and bottom surfaces and the number of surfaces of the base that have the trapezoidal and/or curved edges can be two side surfaces. Embodiments are not limited to these examples.
For instance, in some embodiments, only one side surface of the base may be at a non-right angle to the bottom surface of the base. Also, in some embodiments, more than two side surfaces of the base may be at non-right angles to the bottom surface of the base. For example, in some embodiments, four side surfaces of the base can be trapezoidal or curved (e.g., rounded), or a combination thereof.
In some embodiments, the side surfaces can be angled as discussed above. For instance, in some embodiments, the base has two side surfaces and where each side surface is angled at twenty degrees from a bottom surface of the base. However, embodiments of the present disclosure are not limited to bases having angled side surfaces or to particular angles of the side surfaces.
In various embodiments, the tool can include a pad releasably coupled to the base. In some embodiments, the pad can include a top and bottom surface and a number of side surfaces. A number of the side surfaces of the pad can be at non-right angles to the bottom surface of the pad.
For example, in various embodiments, the pad can include two surfaces that have a rectangular shape and four surfaces that have a trapezoidal shape. In such embodiments, the two surfaces that have the rectangular shape can be the top and bottom surfaces and the four surfaces that have the trapezoidal shape include the side surfaces. An example of such a shape is a truncated pyramid (in a truncated pyramid, the rectangular shapes are typically squares).
In some embodiments, the pad can have two side surfaces and where each side surface is angled at twenty degrees from a bottom surface of the pad. However, embodiments of the present disclosure are not limited to pads having angled side surfaces or to particular angles of the side surfaces. Further, in some such embodiments, such pads can be combined with bases that have one or more angled side surfaces.
In various embodiments, the pad can be sized to include a periphery at least as large as a periphery of the base. In various embodiments, and as shown in
The pad can be formed of a flexible material or a rigid material. For example, the tool can include a flexible pad releasably coupled to the tool base. In such embodiments, the flexible pad can include a top surface defining a recessed portion sized to accommodate the bottom surface and a side surface of the base.
In some embodiments, the pad can be smaller than the periphery of the base. For example, in such embodiments, a pad can be slightly smaller than the base.
In various embodiments, the pad can be releasably coupled to the base on an attachment surface. The tool can include a working material releasably coupled to the pad. In various embodiments, the working material can be selected from a group of materials including a polishing material, a grinding material, a painting material, and a sanding material, among others. In various embodiments, the tool can include one or more fasteners to receive a working material directly or indirectly releasably attached to the tool body selected from a variety of different fastening mechanisms, such as releasable adhesives, hook and loop fastening materials, a number of compression clamps, a number of bolts or screws, or bolt and nut fasteners, among others.
In various tool embodiments, one or more of the components of the tool (e.g., the tool body, the base, the pad, and/or the working material) can each be releasably coupled at an attachment surface. For example, an attachment surface can be used to releasably couple the various components of the tool to each other. For instance, in various embodiments, the attachment surface can include a hook and loop fastening material thereon. In some embodiments, a portion of the working material can wrap around the pad and attach between the base and the pad or to the tool body.
In some embodiments, and as shown in
In various embodiments, the tool component is a pad. In some embodiments, the tool component is a base and the filler material is a pad. In various embodiments, the tool component can include a periphery formed of a material having a lower resiliency than the filler material.
The various embodiments of the present disclosure can be used in a number of ways. For example, in some embodiments, the tool can be applied to a working surface and advanced across the working surface in one or more directions.
Referring now to
The tool 100 includes a number of components that stack above and/or below each other to form a number of layers of various components. In various embodiments, these components can have the same bottom surface shape as the tool body, or one or more of the components can have different bottom surface shapes.
For example, in some embodiments, the tool body 102 can be a rectangular shape while a base component, as will be discussed below, that can be coupled to the tool body 102, has a polygonal bottom surface shape. Embodiments can also have similar or different shaped top surfaces.
As shown in the embodiment illustrated in
In various embodiments, the top surface 104 can accommodate a variety of mechanisms that aid the functioning of the tool 100. For example, in some embodiments, the top surface 104 of the tool body 102 can include a pivoting structure 110 to which a handle can be pivotably coupled. In the example shown, the pivoting structure 110 includes a two piece, two directional structure.
In this example, a first piece 112 having a first pivot point is connected to a second piece 114 having a second pivot point. In various embodiments, a handle can be coupled to the second piece 114, for example, by threading the handle to the second piece 114.
The first piece 112 allows the second piece 114 to pivot radially with respect to the attachment point of a handle coupled to the tool body 102. In this embodiment, the second piece 114 allows a handle to pivot radially with respect to the attachment point of the handle to the tool body 102, and generally perpendicular to the pivotal movement provided by the first piece 112.
The use of the two pieces 112 and 114 allows for the handle to achieve many positions with respect to the tool body 102. However, the embodiments of the present disclosure are not limited to the use of pivotable attachment pieces illustrated in the embodiment of
Further, in some embodiments, the handle can be fixed with respect to, or onto, the tool body 102. For example, a handle can be formed as part of the tool body or can be attached thereto. In some embodiments in which an elongate handle is coupled to the tool body 102, the handle can provide for an increased range of motion or coverage area of tool 100.
In various embodiments, the top surface can include a fastening member to hold a working material in place. In the embodiment shown in
When the fastening member 116 is engaged, for example by moving it from a first position 122 to a second position 124, the elongate member 118 rotates about the spring pivot 120 and pushes a compression member 126 downward to secure a working material (e.g., sand paper, polishing paper, etc.) between the top surface 104 of the tool body 102 and the compression member 126. In some embodiments, the spring pivot 120 precludes the elongate member 118 from independently returning to the first position 122 and, thereby, precludes the working material from releasing from the tool 100 until the fastening member 116 is actuated by a user.
The working material can be secured to the tool 100 in various other manners as well. For example, in various embodiments, the top surface 104 can define openings 128 through which a bolt can extend.
In such an embodiment, a working material or other layer can be secured to the tool body 102 by passing a bolt through the working material and the openings 128 and tightening the working material or layer to the tool body using a nut, such as a wing nut, etc. The working material can also be maintained in position by frictionally holding one or more edges of the working material between two layered components of the tool. In some embodiments, working material can be secured to the tool by coupling the working material directly to a surface (e.g., an attachment surface) of a component of the tool, as will be discussed in more detail below.
A working material can be any type of material that can be utilized to perform work on a surface. Some examples of working materials include, but are not limited to, abrasive materials (e.g., sand paper and/or sanding screens), materials for the application of paint or stain, materials for grinding, and materials for polishing, among others.
In various embodiments, the tool 100 can include a first attachment surface 130 that releasably couples the tool body 102 to another component of the tool, such as a base 132, as will be discussed below with respect to
For instance, in the embodiment of
In the embodiment illustrated in
In the embodiment illustrated in
In various embodiments, the use of fasteners, such as hook and loop fasteners, can provide for an efficient way to replace or detach various components from the tool 100. This allows the tool body to be equipped with various layered configurations. Variations can include the number of layers, the type of layers, the size and/or shape of the layers including the shape of the side surfaces of the layers, etc.
For example, a working material, such as sand paper configured to be releasably coupled to the tool using a hook and loop fastener, can be quickly replaced when the sand paper has become worn, when a different grit is to be used, or when a different type of working material is to be used. The attachment surfaces, including other surfaces of the components of the tool (e.g., a top and/or bottom surface), can include a number of other mechanical and/or chemical fastening mechanisms including but not limited to, glues, epoxies, clamps, and other attachment structures, to name a few.
For example, in some embodiments, the base can be formed of resilient material to provide a flexible base that can compress, give, and/or bend when force is applied to the tool against an object or surface, such as a wall. In various embodiments, the flexible base 132 can have a density of about 600-900 Kg/m3. In some embodiments, the base 132 can, for example, be made of a rubber material.
The use of a flexible base can provide a tactile feel to an operator of the tool 100 as well as increased comfort when using the tool 100. Another benefit is that a base formed of a resilient material can protect the tool from shock when the tool is dropped and can aid in reducing the tendency of the tool to flip when in use.
In the embodiment of
In various embodiments, the top surface of the base can define a recessed portion. In the embodiment illustrated in
The top surface 136, defining the recessed portion 134, can have a variety of shapes. In the embodiment shown in
The recessed portion 134 can be provided in a variety of shapes. For example, in some embodiments, the recessed portion 134 can have a non-planar cross-sectional shape, such as a convex shape or a concave shape.
In various embodiments, and as shown in the embodiment of
In various embodiments, the base 132 can be releasably coupled to the tool body 102 via the first attachment layer 130 and/or attached to the bottom surface 106 (e.g., an attachment surface) of the tool body 102. For example, in various embodiments, the first attachment layer 130 can include a hook and loop fastener where the hook portion of the fastener is attached to or integrated with the bottom surface 106 of the tool body 102 and the loop portion of the fastener is attached to or integrated with the top surface 136 of the base 132, or vice versa.
In some embodiments, the base 132 can be frictionally attached to the tool body 102. For example, frictional force can be applied by top surface 136 and wall surfaces 138. In such embodiments, wall surfaces 138 can apply frictional force to side surfaces of tool body 102 (e.g., side surfaces 108-2 and 108-4 shown in
In various embodiments, the tool 100 can include a pad 142. The pad 142 can be formed from various materials, such as one or more rigid and/or resilient materials. In embodiments where the pad 142 is made from a resilient material (e.g., a sponge, foam, and/or rubber material, among other resilient materials), it can be utilized, for example, to cushion the force of the tool body 102 and base 132 on the surface being worked on, among other benefits. In such embodiments, the pad 142 can have a density of about 30-70 Kg/m3, although embodiments are not limited to a particular density of pad 142.
In various embodiments, the density of the pad 142 is less than the density of the base 132 (e.g., the pad 142 is more flexible than the base 132). In such embodiments, the combination of a more flexible pad layer and less flexible base layer can provide various benefits.
For example, in some embodiments, the pad 142 can be made of an abrasive material (e.g., pad 142 can be a sanding pad) or the pad 142 can have an abrasive material releasably attached thereto. In such embodiments, the combination of a base layer 132 that is more rigid than the pad layer 142 can improve the finish of a surface being worked on, in some instances.
For instance, the base 132 can reduce or prevent a tendency for the tool body 102 to dig into a working surface through the pad layer 142 while it maintains the ability to remove imperfections such as large bumps and/or ridges in the working surface. In such embodiments, the less dense (e.g., more flexible) pad layer 142 can cushion the force of the more dense (e.g., less flexible) base layer 132 against the working surface, among other benefits.
In embodiments where the pad 142 is made from a rigid material, it can be utilized to distribute force more directly to the surface being worked on, among other benefits.
In various embodiments, the pad 142 can be releasably coupled to the base 132 via a second attachment surface (e.g., second attachment surface 340 as shown in
In the embodiment of
For example, various other pad shapes and side surface orientations are possible. For instance, as described further below in connection with
The tool 200 includes a number of components that stack above and below each other to form a number of layers of various components. In various embodiments, these components can have the same shape as the tool body, or one or more of the components can have different shapes.
For example, in some embodiments, the tool body 202 can be a rectangular shape while a base component, as will be discussed below, that can be coupled to the tool body 202, is a polygonal shape. That is, one or more of the top, bottom, or side surfaces of the base component can have various polygonal shapes according to embodiments of the present disclosure.
In the embodiment illustrated in
A low attachment point allows force to be applied at position close to the working surface, such as a wall or other such surface. When the device is operated far from the operator (e.g., via a long handle), this design can be beneficial in reducing the likelihood of flipping the device.
As one of ordinary skill in the art will appreciate, flipping the tool body 202 can result in damage to a working surface such as gouges in the working surface, scuff marks, etc. With embodiments in which flipping is reduced, the tool can be worked more quickly and, in some embodiments, more force can be applied due to the reduced likelihood that the tool will frictionally catch on the surface and flip.
In the example shown in
For instance, the first piece 212 can pivot around the first pivot point 213-1 and the second piece 214 can pivot around both the first and second pivot points 213-1 and 213-2 when the pivoting structure 210 is mounted to the tool body 202. Embodiments of the present disclosure are not limited to the use of pivotable attachment pieces illustrated in the embodiment of
In various embodiments, the tool 200 can include a first attachment surface (e.g. first attachment surface 130 shown in
In the embodiment illustrated in
In some embodiments, the base 232 can be frictionally attached to the tool body 202. For example, frictional force can be applied by top surface 236 and the wall surfaces as described in the embodiment of
In the embodiment illustrated in
The pad 242 can be formed from various rigid and/or resilient materials. In embodiments where the pad 242 is a resilient material, it can be utilized, for example, to cushion the force of the tool body 202 and base 232 on the surface being worked on.
As mentioned above, in some embodiments, the pad 242 can have a density of about 30-70 Kg/m3. The pad 242 can be less dense than the base 232, in various embodiments. As an example, the base 232 can have a density of about 800 Kg/m3.
In such embodiments, the combination of a more flexible pad layer and less flexible base layer can provide various benefits. As one example benefit, the combination of a more flexible pad layer 242 and less flexible base layer 232 can improve the finish of and/or prevent damage to a working surface in corners and/or edge surfaces (e.g., inside corners and/or edges between adjacent walls), in some instances. For instance, in various embodiments, the less flexible (e.g., more dense) base 232 can reduce or prevent the rigid tool body 202 from digging into a corner surface through the pad 242 due to pressure applied to the tool body 202. Additionally, in embodiments where the pad 242 is a rigid material, it can be utilized to distribute force more directly to the surface being worked on.
In various embodiments, and as shown in
Also, as illustrated in the embodiment of
In the embodiment illustrated in
In various embodiments, the use of fasteners, such as hook and loop fasteners, can provide for an efficient way to replace or detach various components from the tool 200. This allows the tool body to be equipped with various layered configurations. Variations can include the number of layers (e.g., one or more layers attached to the tool body), the type of layers (e.g., base layer, pad layer, attachment layer, working material layer), the size and/or shape of the layers including the shape of the side surfaces of the layers, etc.
For example, in the embodiment shown in
In various embodiments, the pad 342 can have a working material formed on the pad 342, or the pad 342 can be constructed of a working material 346 and, therefore, there would be no need for the third attachment surface 344 to be utilized between the pad 342 and the working material 346. In addition, in the embodiment illustrated in
In various embodiments, the tool body 302 includes a top surface that can also include many of the same mechanisms as those described in connection with the top surface 104 of
In the embodiment of
The concave portion 352 of the top surface provides a low attachment point for the pivoting structure 310 with respect to the top surface. A low attachment point allows force to be applied at a position close to the working surface, such as a wall or other such surface. When the device is operated far from the operator (e.g., via a handle 354), this design can be beneficial in reducing the likelihood of flipping the device. As one of ordinary skill in the art will appreciate, flipping the tool body 302 can result in damage to a working surface such as gouges in the working surface, scuff marks, etc.
When a low attachment point is coupled with a wide cross-section of the tool in at least one dimension (typically the dimension in which the tool is to be moved to work the surface), these two elements can further reduce the tendency for the device to flip. With embodiments in which flipping is reduced, the tool can be worked more quickly and in some embodiments more force can be applied due to the reduced likelihood that the tool will frictionally catch on the surface and flip.
In some embodiments, generally uniform diameters of the working material can also allow the tool to be moved in any direction to work a surface with a reduced risk of flipping. For example, circular, square, pentagonal, and hexagonal shapes, among others, provide a generally uniform diameter with respect to the point of connection of the handle, thereby, allowing the tool to be moved in any direction with similar risk of flipping.
When the components are layered upon one another, the openings 456 are in alignment such that a fastener can be extended through the openings to releasably couple the components of the tool 400. For example, as shown in the embodiment of
As previously described herein, the base 432 can include various configurations and shapes and can be formed of various materials. In the embodiment illustrated in
The pad 442 can include various configurations and shapes. In various embodiments, the configurations and shapes can include surfaces that bound each other at non-right angles. For example, the pad 442 is shaped in the form of a polyhedron having surfaces that bound each other at non-right angles. In the embodiment of
In various embodiments, the surfaces 464-1-464-4 incline at an angle from edges 466-1-466-4 and toward surface 462-1. Embodiments can utilize various angles of inclination. For example, in some embodiments, the angle of inclination of the surfaces 464-1-464-4 is 45 degrees. And, in other embodiments, the angle of incline can be more than 45 degrees (e.g., 60 or 70 degrees) or less than 45 degrees (e.g., 30 or 20 degrees). In addition, the angle of incline can vary among the surfaces. For example, a number of surfaces can have an angle of 45 degrees, while a number of surfaces can have an angle of 60 degrees.
In some embodiments, one or more of the edge surfaces 466-1-466-4 can include a serrated edge such as serrated side surface 243-1 shown in
A working material can be releasably coupled to the tool 400 in a number of ways. In various embodiments, a working material can be wrapped around a number of the edges 466-1-466-4 and fitted tightly against a number of the surfaces 464-1-464-4.
In some embodiments, the working material can be secured to the tool 400 by extending the bolt 458 through a portion of the working material at the top surface 404 of the tool body 402 and tightened with a nut, e.g., wing nut 460. In such an embodiment, because the surfaces 464-1-464-4 angle at an incline toward surface 462-1, the working material attached thereto may not contact surfaces adjacent to those being sanded, such as adjacent walls at a corner, a ceiling and wall, a floor and a wall, etc., thus the possibility of gouging or scoring a surface adjacent to a surface being sanded can be reduced.
The use of a flexible base can provide a tactile feel to an operator of a tool to which the base is attached as well as increased comfort when using the tool. Another benefit is that a base formed of a resilient material can protect the tool from shock when the tool is dropped. In some embodiments, the base 532 can be formed of a rigid material which can provide benefits such as distributing force more directly to a surface being worked on.
In the embodiment of

In various embodiments, a working material can be wrapped around a number of the edges 666-1-666-4 and fitted tightly against a number of the surfaces 664-1-664-4. In some embodiments, the working material can be secured to pad 662 by extending a bolt through a portion of the working material and through openings 656 in pad 642 and securing it with a nut, for example. A working material can also be releasably coupled to the bottom surface 662-2 of pad 642 via one or more attachment surfaces (e.g., hook and loop attachment layers) as described herein.
In various embodiments, and as illustrated in

The walls 772 can have a variety of shapes. In the embodiments shown in
In various embodiments, a periphery 763 of the pad 770 forms a portion of the bottom surface 762-2. As shown in
In some embodiments, the pad 770 can have a resiliency such that it is semi-rigid. In such embodiments, it can provide support to a working material but may be resilient enough to act as a bumper to not mar surfaces in which it comes in contact.
Referring now to
However, in various embodiments, the filler material 774 can be flush with the bottom surface 762-2 of the pad. In such embodiments, a first surface of the filler material 774 can be releasably coupled to the bottom surface 762-2 defining the recessed portion 768 via an attachment surface. And, a second surface of the filler material 774 can be flush with the periphery 763 of the bottom surface 762-2.
In various embodiments, the filler material 774 can include a variety of shapes. For example, the filler material can be provided in various circular, oval, polygonal, and other symmetrical and irregular shapes and can have a planar or contoured top and/or bottom surface.
In various embodiments, the filler material 774 can include a resilient and/or a rigid material. For example, in various embodiments, the filler material 774 can be formed from a resilient material such as sponge, foam, and/or rubber materials. And in some embodiments, the filler material 774 can be formed of a rigid material such metal or plastic. Embodiments are not limited to the materials discussed herein.
In embodiments where the filler material 774 includes a flexible material, such as foam, and extends past the bottom surface, as for example, in the embodiment shown
In various embodiments, the filler material 774 can be fabricated from a working material, as the same has been described herein. In some embodiments, the filler material 774 can have an attachment surface thereon to which a working material can be releasably coupled, as discussed herein. For example, in various embodiments, the bottom surface of filler material 774 can provide an attachment surface such as hook and loop fasteners such that a working material can be releasably coupled thereto.
In various embodiments, pad 770 can be releasably coupled to a component of a tool, as the same has been described herein. For example, the top surface 762-1 of pad 770 can be releasably coupled to a tool body via a first attachment surface, such as the tool body and first attachment surface illustrated in
In various embodiments, pad 770 can be releasably coupled to a base via a second attachment surface, such as base and second attachment surface illustrated in
In such an embodiment, the bolt 458 can be designed such that an end of the bolt fits flush with the bottom surface 762-2 defining the recessed portion 768 of the pad 770 so as not to obstruct the filler material 774 releasably coupled to the bottom surface 762-2 within the recessed portion 768. A flush arrangement can also provide a uniform bottom surface of filler material 774 on which the working material is mounted. Therefore, the working material provides substantially uniform pressure on the surface being worked.
Various tool embodiments discussed herein can utilize the layered structure to provide the operator with a tool that has a more cushioned force applied to a working surface. For example, tools utilizing one or more resilient layers can provide such functionality.
Further, the use of one or more rigid layers can provide a more direct translation of force from the handle of the tool to the working surface. Rigid layers can also provide a force to support the number of resilient layers provided thereon. Additionally, the use of one or more resilient layers behind one or more rigid layers, can allow the tool working surface, although rigid, to float somewhat to conform to changes in the working surface, among other uses.
Further, the use of resilient materials can provide one or more small additional working forces. For example, when the resilient layers of the tool are compressed when force is applied in a direction of movement of the tool across a working surface, the resilient layers are deformed. When that force is released, the resilient layers of the tool return generally to their original form.
This reforming motion can be used, in some instances, as an added force to the working surface. This can be beneficial, for example, when sanding a corner, wherein the motion provides a small extra sanding force to the corner area. When multiple layers with the same or different amounts of resiliency are used, multiple different forces can be combined to provide unique force behaviors. By using replaceable layers, a user can change the number, type, size, shape, or other aspects of the layers being used to adjust the forces to be used on a working surface.
Although specific embodiments have been illustrated and described herein, those of ordinary skill in the art will appreciate that any arrangement calculated to achieve the same techniques can be substituted for the specific embodiments shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments of the disclosure.
It is to be understood that the above description has been made in an illustrative fashion, and not a restrictive one. Combination of the above embodiments, and other embodiments not specifically described herein will be apparent to those of skill in the art upon reviewing the above description.
The scope of the various embodiments of the disclosure includes any other applications in which the above structures and methods are used. Therefore, the scope of various embodiments of the disclosure should be determined with reference to the appended claims, along with the full range of equivalents to which such claims are entitled.
It is emphasized that the Abstract is provided to comply with 37 C.F.R. § 1.72(b) requiring an Abstract that will allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to limit the scope of the claims.
In the foregoing Detailed Description, various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the embodiments of the disclosure require more features than are expressly recited in each claim.
Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment.
This application claims the benefit of U.S. Provisional Application No. 60/780,653, filed Mar. 9, 2006, the entire content of which is incorporated herein by reference.
