Abstract

(57) [Abstract] [Purpose] To provide a tape measure provided with a brake button for controlling the storing speed of a measuring tape in a case. [Structure] A brake button provided on the side of the case that controls the rotation of the winding guide that receives the elastic force of the spring.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the improvement of a tape measure.

[0002]

[Prior art]

 The conventional tape measure has a spring and a winding guide to stably store the measuring tape in the case.

With this conventional tape measure, when pulling out the measuring tape for a long time, pull out the measuring tape with the left hand to the length that the arm extends, and then hold the case with the right hand and pinch the measuring tape with the thumb and forefinger. The tape gets caught in the case.

In addition, when the measuring tape is stored in the case after being pulled out for a long time, the spring in the case accelerates the winding of the tape at an accelerating rate. There was a problem that the tip stop claw of the tape hit the hand holding the tape measure and got injured.

[0005]

[Problems to be solved by the device]

 The purpose is to provide a brake that stops the rotation of the winding guide that transmits the spring action when the measuring tape is wound into the case.

[0006]

[Means for Solving the Problems]

 A tape measure that has a brake button on the side of the case, which is a tape measure that is wound into the case by a spring that contains a measuring tape.

[0007]

[Action]

 When the brake button on the side of the case is pressed with the finger holding the tape measure case, the rotation of the winding guide that transmits the action of the spring is suppressed and the winding of the measuring tape can be stopped.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a tape measure, which has a circular brake button 8 on a side surface of a case 2 of the tape measure 1, and a stop claw 4 is fixed to the tip of a measuring tape 3 which is slightly pulled out from the case 2.

FIG. 2 is a cross-sectional view of the tape measure 1. The tape measure 1 is rotatably placed on the central shaft 5 from one case 2. A spring 7 is provided in the inner cylinder of the winding guide 6, and one end of the spring 7 is at the central shaft. The other end of the measuring tape 3 is fixed to the other end of the measuring tape 3 through the winding guide 6. The measuring tape 3 is wrapped around the outer circumference of the cylinder of the winding guide 6. The stepped circular brake button 8 projects from the side surface of the case 2, and the brake surface 9 contacts the guide side surface 10 of the winding guide 6.

When the measuring tape 3 is pulled out from the case 2, the winding guide 6 is rotated, and then the spring 7 is tightened. On the contrary, when the pulled-out measuring tape 3 is released, the measuring tape 3 is wound into the case 2 due to the resilience of the spring 7 which returns from the tightened state to the unwound state. The measuring tape 3 was rolled up at an accelerated rate, and the measuring tape 3 was twisted, causing some bounds, and the stop claw 4 at the tip of the measuring tape 3 hit the finger with the tape measure 1 and felt painful. As a method of preventing the measurement tape 3 from twisting or bouncing at this time, when the brake button 3 that indirectly restrains the storage speed of the measurement tape 3 is pressed, it is connected to the measurement tape 3 by the friction resistance between the brake surface 9 and the guide side surface 10. The rotation of the winding guide 6 is stopped. Since the brake button 8 has a stepped circular shape and is rotatable, the brake surface 9 is uniformly worn as a result of variations in the wear of the brake surface 9. Further, since the brake button 8 has a circular shape, it can be easily removed by rotating it even if dust, sand or the like is caught therein.

[0011]

[Effect of the Invention] As described above, according to the present invention, the accelerative storage speed of the measuring tape in the case, which is pulled out by pressing the brake button protruding from the side of the case with the fingers of the tape measure, can be increased. As a result of being able to stop, it became excellent in safety.
