Exemplary embodiments of the present invention relate generally to brakes and brake assemblies that are adapted to be used to bend or cut material.
Brakes and brake assemblies may be used to bend or cut aluminum sheet material in order to form various siding and trim pieces. Brake assemblies may include accessories to facilitate the bending and cutting processes. In a known example, a measurement tool is secured to a moving hinge of a brake assembly, such that the measurement tool is positioned beneath the material to be bent or cut. A known measurement tool requires a lengthy and difficulty installation onto the brake and also to remove from the brake. In particular, a known measurement tool is comprised of a steel base that must be screwed to the moving hinge, wherein a magnetic scale extends from the steel base. This requires the drilling of holes in the metal moving hinge. Furthermore, in order to be able to cut or bend the material, the measurement tool must be unscrewed from the moving hinge, which is again cumbersome and also leaves the holes in the moving hinge. Additionally, the bulky steel base and magnetic scale of the known measurement tool makes the brake assembly (particularly the anvil) heavy, which may also make the brake assembly cumbersome to operate or transport.
An exemplary embodiment of the present invention may address any of aforementioned shortcomings of the known art. One exemplary embodiment is a measurement tool comprising a base portion that is adapted to be positioned over an upper clamping portion of a brake, wherein an elongated portion of the measurement tool extends from the base portion to facilitate measurement of material to be bent or cut. In one exemplary installation method, a base portion of an exemplary embodiment of the measurement tool may simply be clipped onto a rear edge of an upper clamping portion, which may be done manually without compromising the brake with holes. Furthermore, in an exemplary removal method, a base portion of an exemplary embodiment of the measurement tool may simply be unclipped from the brake, which again may be done manually without compromising the brake. Moreover, an exemplary embodiment of a measurement tool may be lighter and more cost effective relative to the aforementioned known measurement tool due to its installation over an upper clamping portion of a brake, which more effectively supports the measurement tool.
An exemplary embodiment of a measurement tool may also comprise a material stop positioned on an elongated portion to facilitate measurement of material to be bent or cut. In one example, a material stop may be slidably positioned on an elongated portion to select a measurement of material to be bent or cut. An exemplary embodiment of a material stop may comprise a fastening device to set a desired position of the measurement tool on an elongated portion. Moreover, an exemplary embodiment of a material stop may be selectively positioned (e.g., initially or after initial installation) on an elongated portion to facilitate operation of a fastening device by a left-handed person or a right-handed person. In an exemplary operation, material may be abutted against a material stop to set a desired length of material to be bent or cut.
An exemplary embodiment of a measurement tool may also comprise a pivot portion adapted to facilitate movement of the measurement tool to facilitate a bending or cutting process. One example of a pivot portion is a hinge, but may comprise other types of pivot mechanisms. While, as aforementioned, an exemplary embodiment of a measurement tool may simply be removed from an upper clamping portion of a brake as needed, an exemplary embodiment of a pivot portion may obviate the need for removal. In particular, an exemplary embodiment of a pivot portion may facilitate rotation of a measurement tool out of the way for a bending or cutting process. More particularly, an exemplary embodiment of a pivot portion may facilitate vertical rotation of a measurement tool over an upper clamping portion. Still more particularly, an exemplary embodiment of a pivot portion may facilitate vertical rotation of a measurement tool over an anvil portion of an upper clamping portion.
Exemplary embodiments also include related brake assemblies and methods for installing a measurement tool. While exemplary embodiments may be particularly useful for bending or cutting aluminum sheet metal into siding and trim pieces, other exemplary embodiments may be useful for other types of material or end uses unless otherwise noted.
In addition to the novel features and advantages mentioned above, other benefits will be readily apparent from the following descriptions of the drawings and exemplary embodiments.
Exemplary embodiments of the present invention are directed to a measurement tool that is adapted to facilitate the measurement of material that is to be bent or cut by a brake.
Measurement tool 10 comprises a base portion 12 that is adapted to extend or be positioned over (i.e., above) an upper clamp portion (or equivalent) of a brake when installed. An elongated portion 14 is adapted to measure a piece of material that is adapted to be bent or cut by a brake. For this purpose, elongate portion 14 comprises a a desired scale 14B on at least one side of elongated portion 14.
In an exemplary embodiment, an elongated portion extends from a distal portion or end 12A of base portion 12 and away from an upper clamp portion (or equivalent). However, in other exemplary embodiments, an elongated portion may extend from another portion of a base portion. Additionally, elongated portion 14 is also adapted to extend above material that is adapted to be held between an upper clamp portion and the lower clamp portion of a brake.
This example of base portion 12 may also comprise a pivot portion 16 adapted to facilitate movement of measurement tool 10 to facilitate a bending or cutting process (e.g., with respect to material adapted to be held between an upper clamping portion and a lower clamping portion of the brake. In particular, pivot portion 16 is adapted to facilitate movement of base portion 12 and elongated portion 14 such as shown in
In this embodiment, pivot portion 16 is adapted to facilitate rotation of measurement tool 20 over an upper clamping portion of a brake to facilitate a bending or cutting process with respect to material adapted to be held between the upper clamping portion and a lower clamping portion of the brake. More particularly, pivot portion 16 is adapted to facilitate vertical rotation of measurement tool 20 over an upper clamping portion of a brake (e.g., adapted to facilitate vertical rotation of measurement tool 20 away from an anvil portion of an upper clamping portion of the brake. Other embodiments of a pivot portion may be adapted to facilitate different types of movement of a measurement tool.
This example of base portion 12 may also comprise a clip portion 18 that is adapted to facilitate positioning of base portion 12 on an upper clamp portion of a brake. In this example, clip portion 18 is part of the proximal portion of 12B of base portion 12, and is associated with pivot portion 16 to facilitate rotation of elongated portion 14 and a portion of base portion 12. In other embodiments, a clip portion may be located at a different portion (e.g., an intermediate or distal portion) of a base portion. In this example, clip portion 18 comprises a U-shaped portion 18B that is adapted to extend around an edge of an upper clamp portion. Also, in other embodiments, a base portion may comprise a different type of attachment portion (e.g., magnetic, clamping, suction, etc.), or may not comprise an attachment portion (e.g., such that a measurement tool is adapted to simply rest on an upper clamp portion or otherwise be associated with brake).
In this example, clip portion 18 is further adapted to engage a bottom side of the upper clamp portion of the brake such as best shown in
This example of measurement tool 10 may also comprise a material stop 20. In this example, material stop 20 is adapted to be slidably positioned on elongated portion 14 such that a desired length of material is adapted to abut material stop 20 to facilitate bending or cutting of the material. Other embodiments of a material stop may be positioned relative to an elongated portion in a different manner. This embodiment of material stop 20 has a planar surface 20A that is adapted to abut a piece of material that is to be bent or cut by a brake. Furthermore, planar surface 20A is adapted to facilitate measurement. In particular, material stop 20 is adapted to be set relative to scale 14B on elongated portion 14 to facilitate determination of a length of material adapted to be held between the upper clamping portion and the lower clamping portion of the brake from planar surface 20A to an upper clamping portion of a brake. However, other embodiments of a material stop may have a different shape of a surface that is adapted to abut a piece of material that is to be bent or cut by a brake and/or to facilitate measurement.
This embodiment of material stop 20 also comprises a fastening device 20B adapted to secure material stop 20 to elongated portion 14. In particular, fastening device 20B is a thumb screw that is adapted to engage a lateral side 14C of elongated portion 14 on which there is not a scale. Other embodiments of a fastening device may be adapted to engage a different portion (e.g., bottom) of an elongated portion. Also, other embodiments of a fastening device may comprise a different fastener or may not comprise a fastening device (e.g., magnetic).
This embodiment of material stop 20 is also adapted to be selectively positioned on elongated portion 14 to facilitate operation of fastening device 20B by a left-handed person or a right-handed person. For instance,
