Abstract: A dual mode tape rule blade arrestor structure that provides for an effective increase in tape rule rewind buffering to prevent excessive blade retrieval speeds that generate high impact sheering forces. The arrestor button of the present invention is pressed upward to temporarily halt tape rule rewinding, but can at the same time also be pressed downward and locked into the full constraint position. As such, the improved structure of the invention herein enhances tape rule service life as well as operating safety.

Abstract: The present invention discloses a measuring tape having a quick and effort-saving retracting device, comprising a front casing, a rear casing, a measuring tape axle base, a reverse axle, a reverse gear, a fastener, a gear casing, and a driving axle rod; more particularly a measuring tape that provides a retraction for a long-distance measurement and a device having a quick and effort-saving effect for enhancing the practicability of a measuring tape.

Abstract: A tape measure having a quick rewinding mechanism. The mechanism includes a gear assembly having a first drive gear, a second drive gear, and an idler gear set having first, second, third, and fourth idler gears each meshed with the first drive gear, wherein the idler gears are equally spaced around the first drive gear for uniformly distributing a generated force to the idler gears while rewinding the tape measure device.

Abstract: A tape rule blade having graduations in an eye-catching third color, wherein the numerals of the graduations on the tape rule blade are in numeric characters of a first color, numeric characters of a second color, and numeric characters of the eye-catching third color to facilitate the visual separation of adjacent numeric characters. At the same time, the alerting effect also afforded prevents sighting errors and reading inaccuracies, with the tape rule blade thereby having even more practical value through an innovative design.

Abstract: A tape measure. The tape measure includes a lock device at a bottom opening, an engagement device, and an abutment device. To pull or rewind tape, the front end of control device is pressed to cause both the lock device and the engagement device to pivot upwards, thus allowing tape to be pulled or rewound freely. When the lock device is released, this causes both the lock device and engagement device to pivot in a reverse direction for locking tape. The locking/unlocking of tape is effected in an up-and-down movement of the front end of the lock device.

Abstract: An improved structure art design knife comprised of a front cover, a rear cover, an upper support cushion, a lower support cushion, a blade magazine section, and a blade arrestor section. In addition to providing for convenient blade replacement, the blade magazine section contains a quantity of spare blades to thereby increase art design knife efficiency and, furthermore, enhance the industrial practical value of art design knife structures.

Abstract: A flexible rule rewinding device comprised of a front cover plate, a rear cover plate, a winding shaft, a center gear, two gears, a flexible rule reel mount, and a cover plate capable of rewinding long distance flexible rules rapidly and with little effort to thereby increase flexible rule practicality.

Abstract: A tape measure having a quick rewinding mechanism comprises a gear assembly including a first drive gear, a second driven gear, and an idler gear set having a first, a second, a third, and a fourth idler gears each meshed with the first drive gear wherein the idler gears are equally spaced around the first drive gear for uniformly distributing a generated force to the idler gears while rewinding the tape measure device.

Abstract: A taper ruler coating nylon resin forming structure that includes mainly a forming structure body, a guide locator stem body, a positioning block, a forming die, and a stopper. The structure provides an improved forming structure for producing pre-printed tape ruler strips that are coated with a layer of nylon resin. The coating give the strips improved suppleness and increased wear resistance against frictional abrasion.

Abstract: A tape rule blade arrestor device of the invention herein is comprised of a right case half, a left case half, a bumper block, a tape reel, and other components that provides an improved structure for the rewinding of the tape rule blade having the capability to enhance cushioning and arresting performance to prevent the enormous shearing stress generated by excessive rewinding speed, and thereby increasing tape rule service life and safety.
