A7 _ B7___ V. Description of the invention (1) [Application fields in the industry] (Please read the precautions on the back before filling out this page) The present invention relates to a tape measure that can be wound and stored in a box, and more particularly A tape measure capable of reducing the rotational frictional resistance of a rotating drum when a tape is wound. [Known Techniques and Problems] Nowadays, an automatic winding type tape measure capable of automatically winding a measuring tape is widely used. Its structure is such that a tape is wound around a roll body and is installed inside. The reel includes a rotating reel with a coil spring as an elastic means for winding the tape, and a case for accommodating the rotating reel. Usually, since the tape is housed in the box, during the measurement, the locking piece provided at the front end of the tape that is locked at the tape entrance and exit of the box is pulled with your fingers, and the tape is properly pulled out to perform the measurement. Determination. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the measurement tape is to be stored in the box after the measurement is completed, the brake is stopped automatically by using the tape brake device or the hand to release the tape. The reel spring of the rotating reel installed in the box body is wound into the box body, and then the locking piece at the front end of the tape is locked at the tape inlet and outlet to complete the winding of the tape. A buffer member is provided at the entrance and exit of the tape measure to mitigate (also including absorption) the impact energy of the locking piece that hits the entrance and exit of the tape measure at a considerable speed. 0 In the tape measure, the box may be used to wind the tape.

Rotary reel In order to prevent the resin from welding with each other when the tape is pulled out or wound, the rotating reel is between the rotating reel and the base of the shaft It is provided with a gap. That is, the rotating drum is supported by the shaft on the shaft portion in a loosely fitted state, so its rotation is a rotation that contacts the shaft portion or the inner wall, and this rotation will cause great friction. Rotation under resistance (contact resistance). Therefore, the coil spring used to wind the tape is designed with this frictional resistance in mind, so that the rotating reel can rotate smoothly without necessarily using high torque The high torsion coil spring can produce high torsion by increasing the thickness of the leaf spring material, or widening the width of the leaf spring material, or increasing the length of the leaf spring, or increasing the hardness. However, With the use of high-torque coil springs, greater tension is required when the tape is pulled out, and because the tape is wound back at high speed at the same time when winding the tape, there may be injuries to fingers on the edges of the tape. It is dangerous and reduces the life span of the tape hook. Moreover, the weight of the coil spring also makes the tape measure heavier and larger. It also increases its cost. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Due to the vibration of the rotating reel, the sound is also very loud when the tape is pulled, and it can not make people feel valuable in terms of price.
