Abstract: A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.

Abstract: A chalk line device includes a housing, a spool, a chalk line, a hook, and a cap. The housing defines an outer surface and an internal chamber, and the housing includes an opening. The spool is supported in the internal chamber for rotation relative to the housing. The chalk line extends through the opening of the housing and the chalk line includes a first end and a second end. At least a portion of the chalk line is wrapped around the spool. The hook is secured to the first end of the chalk line and includes a tip adapted to engage a work piece. The cap is removably coupled to the housing to cover the opening. The cap includes a nozzle through which the chalk line extends and a projection for engaging and releasably securing the hook against the cap.

Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.
Abstract translation: 螺丝刀包括主体和开关。 主体联接到手柄并且包括一对平行的间隔开的狭槽和位于每个狭槽中的棘爪。 每个棘爪都被弹簧向外偏压。 开关可相对于主体枢转，并且开关包括沿着内表面的弓形部分延伸的凹槽。 以第一方向旋转开关将开关移动到第一位置，在第一位置，凹槽与第一棘爪成一直线。 当开关处于第一位置时，第一爪从槽向外延伸并接合内齿表面，使得沿第一方向施加转矩沿第一方向驱动柄，并且在第二方向施加扭矩导致 柄相对于主体棘轮。

Abstract: A tool, such as a tape measure, including a spring-based retraction system is shown. The spring-based retraction system includes at least two springs that drive a tape spool during tape retraction. The springs are indirectly coupled to each other via a single center post, in one embodiment, two center posts on a single spool, in another embodiment, or two center posts that are on different spools, in another embodiment.

Abstract: A workpiece engaging surface that includes a pattern of laser-etched channels and related method of manufacturing is provided. The laser-etched pattern on the surface of the workpiece engaging surface is formed by multiple groupings of closely spaced channels that generate serrated teeth in the surface of the tip. Each grouping of channels is formed by passing a laser over a first location a first number of passes to form a first channel, passing a laser over a second location, spaced apart from the first location by a channel spacing distance, a second number of passes to form a second channel, and passing a laser over a third location, spaced apart from the second location by the channel spacing distance, a third number of passes to form a third channel. In some embodiments the first, second, and third number of passes are the same.
