Description

Technical Field [0001] The present invention relates to a handle fixing device for winding a tape measure having a handle reverse rotation prevention function,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape measure, and more particularly, to a tape measure having a function of preventing the handle from rotating in a fixed state without rotating the handle even if the tape measure is released, The present invention relates to a handle fixing device for winding a tape measure provided with a handle anti-rotation function capable of maintaining a fixed state of a handle at a position where a tape can be wound so as to enable continuous winding.

In general, a tape measure is built in a case in which a tape coupled with a spring is wound on a bobbin in the form of a coil and a hook coupled to a tape end is exposed to the outside of a slot formed at a lower side of one side of the case, The tape inside the case is taken out to the outside of the case, and when the hook is released, the tape pulled out by the elasticity of the spring is configured to be pulled into the case.

In addition, some types of tape measure are provided with a locking means for preventing the tape from being retracted by the spring tension and being wound into the case even when the pulling tension applied to the hook of the tape end is removed in a state of being drawn out of the case.

Meanwhile, in case of a tape measure used for measuring lengths and distances used in various industrial sites, homes, athletics fields, and the like, the cross-shaped upper and lower cases are coupled by a plurality of coupling pins, A spike is attached to the front and a handle is integrally formed at the rear.

The reel unit includes a rotary cap mounted at the center of the upper case, a handle fixed to the rotary cap by a hinge pin, and a reel including a bobbin wound around the coupling protrusion of the rotary cap and winding a tape measure.

The tape measure having the above structure is manufactured in various lengths of 30 to 100 m so as to measure a long distance and is wound on the bobbin. When using the tape measure, the tip end of the tape measure is fixed to one measurement point, And the spike is fixed on the ground. Then, the scale is read to measure the distance.

Meanwhile, when the tape measure is loosened during use, the bobbin rotates. At this time, the handle connected to the bobbin rotates together. When the handle rotates, the tape measure hits the hand of the user holding the tape measure during the measurement process, Which causes many inconveniences.

To solve the above problem, a tape measure is proposed in Korean Patent No. 10-1476322 that enables the handle to be kept in a fixed state without rotating even if the tape measure is released.

The tape measure comprises a top and a bottom case, a flange portion attached to one side of the top case and having a handle shaft passing through the top case at the center, and a rod portion connected to the flange portion in a pin- and; A bobbin located on the inner space of the upper and lower cases and having an outer peripheral surface on which a tape measure is wound; A disk disposed between the bobbin and the upper case and having an engaging hole for engaging with the handle shaft at a center and rotating by the rotational force of the handle; A protrusion formed on one side of the disc and having a first gear at its tip; Wherein the disc is formed with an insertion groove formed on an inner surface thereof with a second gear selectively in contact with the first gear of the disc and a hole formed in a flange portion of the handle, And the end is pressed in accordance with a tilting operation of the rod portion in a state of being in contact with the rod portion so as to press the disk to engage the first gear of the disk with the second gear of the bobbin .

In order to wind the tape measure, the presser bar presses the disc so that the first gear of the disc is engaged with the second gear of the bobbin. However, In order to maintain the pressurized state, the handle must be rotated in a state in which the handle is pressed so as to press the pressing pedal, which is inconvenient for use.

At the lower end of the fixed shaft (50), a fixing hole (52) for screw tightening is formed.

The rotating body 5 is provided with a flat surface portion 53 on the upper surface of the fixed shaft 50 and is provided between the protrusions 54 and 54a so as to fix the handle 6 on the flat surface portion 53 A handle seat space 55 is formed.

The protrusions 54 and 54a are formed with shaft holes 56 and 56a into which the fixing shaft 7 for fixing the handle 6 is inserted and the protrusions 54 and 54a 58a and the insertion grooves 59, 57a are formed on one side surface of the concave grooves 57, 57a while the concave grooves 57, 57a are formed on the inner side surfaces of the concave grooves 57, And 59a are formed.

The handle 6 includes a fixed end portion 60 and a rotary end portion 61. The fixed end portion 60 has a sliding hole 600 in which the fixed shaft 7 is inserted, The elastic member insertion groove 601 is formed so as to coincide with the shaft holes 56 and 56a formed in the protrusions 54 and 54a and connected to the sliding hole 600 so that the first elastic member 8 And fixing protrusions 602 and 602a inserted into the insertion grooves 59 and 59a are formed in the recesses 57 and 57a formed in the rotary body 5, respectively.

The first elastic member 8 is formed of a support portion 80 and elastic portions 81 and 81a so that the support portion 80 is supported by the handle 6 and the elastic portions 81 and 81a are engaged with the shaft hole 56 and 56a and the fixed shaft 7 inserted in the sliding hole 600. [

On the other hand, the bobbin 2 is rotated by receiving the unidirectional rotational force of the handle 6 by the clutch means, and can rewind the tape measure 3 drawn out to the outside.
