DETAILED DESCRIPTION
[0017]
[0018] The scraper blade 18 includes a first scraping edge 20 at a first end 32 of the scraper blade 18 and a second scraping edge 22 at a second end 34 of the scraper blade 18 generally opposite the first end 32. Thus, the scraping edges 20, 22 are disposed on generally opposite distal ends of the scraper blade 18. In the illustrated construction, the scraper blade 18 is concave and generally forms a quadrilateral shape. The scraper blade 18 includes a concave surface 86 and a convex surface 88 opposite the concave surface (
[0019] The first and second scraping edges 20, 22 may have different forms for different scraping applications. For example, the first and second scraping edges 20, 22 may have any combination of one or more of differing sharpness, bluntness, shape, bevel angle, texture, grit, etc. In the illustrated construction, the first scraping edge 20 is a blunt edge and the second scraping edge 22 is a razor edge. As such, the first and second scraping edges 20 have different forms, e.g., different sharpness. In the illustrated construction, the first scraping edge 20 has a length L1 (
[0020] In the illustrated construction, the first and second scraping edges 20, 22 are scraping edge members that are removably fastened to the first and second ends 32, 34 of the scraper blade 18, respectively. For example, the first and second scraping edges 20, 22 are removably fastened by one or more fasteners 36 such as screws, nuts and bolts, clamps, clips, pins, etc. In other constructions, the first and second scraping edges 20, 22 may be formed at the first and second ends 32, 34 of the scraper blade 28, e.g., from the same single piece of material as the scraper blade 18 or fixedly coupled thereto, e.g., by rivets or welding.
[0021] A connecting member 24 extends from the convex surface 88 of the scraper blade 18 generally normal to the convex surface 88 of the scraper blade 18 and defines an axis B (
[0022] In the construction illustrated in
[0023] The scraper blade 18 is removably and adjustably mounted to the elongated handle 12 by an adjustable coupling 26. As shown in
[0024] In the construction illustrated in
[0025] The scraper tool 10 also includes a guard 46 for covering one of the first or second scraping edges 20, 22 not in the working position 44 (i.e., in a non-working or storage position 90). The guard 46 covers the first scraping edge 20 when the scraper blade 18 is in the second position and covers the second scraping edge 22 when the scraper blade 18 is in the first position.
[0026] The guard 46 includes a generally linear recess 48 (or channel) formed therein for receiving the one of the first or second scraping edges 20, 22 in the non-working position 90. The guard 46 substantially covers the edge 20, 22 in the non-working position 90. For example, the guard 46 may be formed from a piece of sheet metal, or other material, bent or formed to define the recess 48.
[0027] The guard 46 is jointly coupled to the elongated handle 12 and the connecting member 24 of the scraper blade 18 by way of the fasteners 42. However, in other constructions, the guard 46 may be coupled to the scraper blade 18 or to the elongated handle 12 independently. In the illustrated construction, the guard 46 includes a pair of mounting brackets 50 spaced in a generally parallel fashion to receive the first and second mounting members 24a, 24b and the elongated handle 12 therebetween. The mounting brackets 50 include apertures therethrough for receiving one of the fasteners 42, which sandwiches the mounting brackets 50, the mounting members 24a, 24b, and the elongated handle 12 together. In other constructions, the guard 46 may be mounted in other suitable ways.
[0028] The scraper tool 10 also includes stomps 52a, 52b. Each of the stomps 52a, 52b extends transverse to the axis A, e.g., substantially perpendicular to the axis A as illustrated. The stomps 52a, 52b are coupled to the handle 12 proximate the first distal end 28 and extend from opposite sides of the handle 12. In other constructions, the stomps 52a, 52b may be coupled to the scraper blade 18 or to the guard 46. In the illustrated construction, each stomp 52a, 52b is formed from a bar fixedly coupled to the handle 12, e.g., by welding or the like, which extends transverse to the axis A. The bar may be straight or bent, as shown. In some constructions, only one stomp is employed.

[0031] In the construction illustrated in
[0032] With further reference to
[0033] The adjustable coupling 226 also includes a pivot plate 68 disposed between the collar 58 and the handle 12. The scraper blade 18 is removably coupled to the collar 58, which is fixedly coupled to the pivot plate 68, and the handle 12 is pivotably coupled to the pivot plate 68 by way of a pivot pin 70. A locking mechanism 72 allows the handle 12 to be held in a plurality of positions with respect to the scraper blade 18. Any suitable locking mechanism may be employed. For example, the locking mechanism 72 includes a locking pin 74, as shown. In other constructions, the locking mechanism 72 may include a biased protrusion coupled to the handle 12, a fastener such a nut and bolt, a screw, or any of the fasteners described above, etc. In the illustrated construction, a plurality of apertures 76 are disposed in the pivot plate 68 for receiving the locking pin 74. The locking pin 74 is selectively received in any one of the plurality of apertures 76, each corresponding to a different angle between the handle 12 and the scraper blade 18.
[0034]
[0035]
[0036] The adjustable coupling 426 includes the connecting member 424. The connecting member 424 includes a tube 478 defining an elongated cavity 438 extending generally perpendicular to the axis B for receiving the handle 12. In the illustrated construction, the tube 478 is generally cylindrical; however, in other constructions the tube 478 may have any extruded shape, or any other shape defining an elongated cavity for receiving the handle 12. The tube 478 is fixedly coupled to the scraper blade 18. The tube 478 may be coupled to or formed as one piece with first and second mounting members 424a, 424b extending fixedly from the scraper blade 18. In some constructions, the tube 478 may be directly coupled to the scraper blade 18, or other mounting members may be employed. The tube 478 has in inner diameter sized to receive the handle 12 therein. A fastener (not shown) such as any of the fasteners described above (e.g., the removable pin 60 with the securing member 62 described above and shown in
[0037] The adjustable coupling 426 is generally symmetrical about the axis B for receiving the handle 12 in the cavity 438 from either side of the axis B. In a first position, the handle 12 is received from the second end 34 of the scraper blade 18 such that the first scraping edge 20 is in the working position 44 opposite the second distal end 30 of the handle 12. In a second position (e.g., refer to the phantom lines in
[0038] The guard 446 includes a stomp member 452 having a stomp surface 480 generally facing the second distal end 30 of the handle 12 and disposed proximate the first distal end 28 of the handle 12. The stomp surface 480 may be disposed generally perpendicular to the axis A, e.g., such that the axis A is normal to, or varies slightly from normal to, the stomp surface 480. The stomp surface 480 provides a surface for the operator's foot to stand or stomp on the scraper tool 10. The stomp surface 480 also acts as a guard over the scraper blade 18. As illustrated in
[0039] The guard 446 includes a support, such as first and second support members 482a, 482b, supporting the stomp member 452. The support members 482a, 482b extend from, and are coupled to, the handle 12. The support members 482a, 482b may include bars, tubes, wires, etc. or another suitable framework. The handle 12 may include an enlarged diameter portion 484 acting as an axial stop against the tube 478 and providing a mounting location for the support members 482a, 482b. The enlarged diameter portion 484 may be separate from the handle 12 such that the handle 12 is received therethrough, or may be fixed to the handle 12.
[0040]
[0041] The alternate constructions of the features described herein may be employed in any combination. For example, any of the stomps or guards may be used in any combination with each other and in any combination with the adjustable couplings described herein.
[0042] In operation, an operator may move the scraper blade 18 from the first position to the second position to selectively secure one of the scraping edges 20, 22 in the working position 44. The scraper blade 18 may be rotated about the axis B, e.g., by 180 degrees, between the first position and the second position (
[0043] The operator may also change the scraper blade 18 from one side of axis A of the handle 12 to an opposite-facing side of the axis A of the handle 12 (
[0044] The scraper tool 10 may be used for scraping a surface, such as a floor, a ceiling, a wall, etc. Different positions of the scraper blade 18 provide different scraping edges 20, 22 having different forms, such as a blunt edge for certain applications and a razor edge for other types of applications. The scraping edges 20, 22 also differ in length L1, L2 to provide different functionality in one tool.
[0045] For added power during use, the operator may apply force on the stomps 52a, 52b, 452, e.g., by way of one's foot.
[0046] Thus, the invention provides a scraper tool 10 with an adjustable scraper blade 18 having a guard.
[0047] Although the invention has been described in detail with reference to certain preferred constructions, variations and modifications exist within the scope and spirit of one or more independent aspects of the invention as described.
