Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape measure used for surveying or the like.

[0002]

[Prior art]

 As a tape measure used for surveying, etc., a long tape indicating the distance is wound around the reel tube inside the reel case, and the reel tube is rotated by turning the handle pivotally supported on the outside of the reel tube to wind the tape. The structure of taking is used.

[0003]

[Problems to be solved by the device]

 In this type of conventional tape measure, the handle is directly supported by the end of the reel tube rotatably supported in the reel case, so if you rotate the handle to rotate the reel tube, the tape Can be rolled up. However, when pulling out the tape from the reel case, the tape may be pulled out while moving while holding the reel case at a certain point such as the ground and holding the tip of the tape. Also causes the handle to rotate.

For this reason, when the reel case falls down during pulling out, the handle is pressed against the ground and its movement is suppressed, so that there is a problem that the tape cannot be pulled out.

The present invention has been made to solve the above problems, and prevents the handle from rotating when the tape is pulled out, so that the tape can be pulled out well even if the reel case falls over. The purpose is to provide a tape measure that can

[0006]

[Means for Solving the Problems]

 For this reason, in the tape measure of the present invention, the reel cylinder is rotatably supported in the reel case, the engaging portion is provided at the end of the reel cylinder, and the handle base with the handle attached to the outside is the engaging portion. And a spring that is rotatably supported by the reel case outside the engaging portion and that biases the handle base in the non-engaging direction.

[0007]

[Action / effect]

 In the tape measure thus constructed, the handle base is normally biased toward the non-engaging side by the spring, and the handle base and the engaging portion of the reel cylinder are not engaged. For this reason, the reel cylinder is in a rotatable state, and if the user pulls out the tape by holding it, the reel cylinder rotates and the tape is pulled out. When the tape is pulled out, the handle base and the handle do not rotate, so the tape can be pulled out smoothly even if the reel case falls over.

On the other hand, when winding the tape, the handle base is pushed to engage the engaging portion of the reel cylinder with the engaging portion, and the reel cylinder is rotated while rotating and operating the handle, and the tape is wound onto the reel cylinder.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the tape measure, and FIG. 2 is a sectional view thereof. Reference numeral 1 denotes a reel case. In the reel case 1, a reel cylinder 2 has a front end portion thereof engaged with a circular support portion 1a in the reel case 1, and a shaft portion 2a projectingly provided at a rear end portion thereof. The reel case 1 is rotatably supported by being inserted into a support hole 1b formed in the center of the rear surface of the reel case 1. The reel cylinder 2 is wound with a long tape 3 indicating the distance. A metal ring for a bearing is fitted into the circular support portion 1a and the support hole 1b of the reel case 1 to reduce frictional resistance.

Further, as shown in FIG. 4, a short cylindrical engagement portion 4 is projectingly provided at the center of the front end portion of the reel cylinder 2, and the engagement portion 4 is provided with an engagement pin 5c described later. Engaging recesses 4a to be engaged are provided at two places. The engaging recess 4a is easily engaged when the later-described engaging pin 5c rotates in the winding direction of the tape 3, and easily disengaged when rotating to the non-winding side. The reel cylinder 2 is formed so as to be obliquely inclined in the winding direction.

The front center portion of the reel case 1 has a circular opening so as to expose the engaging portion 4 of the reel tube 2 described above, and the handle base 5 can be attached to the outside of the engaging portion 4 so as to cover it. To be The handle base 5 is configured by providing a cylindrical engagement cylinder 5b at the center of the inside of a circular cup-shaped main body 5a, and the engagement recess 5a of the engagement section 4 is engaged with the outer periphery of the engagement cylinder 5b. Two engaging pins 5c that can be fitted are provided in a protruding manner.

A metal flange 5d having a diameter larger than that of the opening of the reel case 1 is attached to the outer periphery of the main body 5a of the handle base 5, and the flange 5d is attached to the inner peripheral edge of the opening of the reel case 1. Upon contact, the handle base 5 is rotatably supported at that portion. Further, a shallow groove is provided in the transverse direction on the outer front surface of the main body 5a, and the handle 6 is mounted in the groove via the shaft 6a. When not in use, the handle 6 can be turned over 180 degrees via its shaft 6a and locked on the upper part of the reel case.

The handle base 5 having such a structure is assembled as shown in FIG. 2 and, as shown in FIG. 4, between the engaging portion 4 at the end of the reel cylinder 2 and the engaging cylinder 5b of the handle base 5. The coil spring 7 is interposed. The coil spring 7 biases the handle base 5 outward, that is, in the non-engaging direction of the engaging portion 4. Therefore, normally, as shown in FIG. 2, the handle base portion 5 is biased to the most outwardly projecting position, and the engagement concave portion 4a of the engagement portion 4 and the engagement pin 5c on the engagement cylinder 5b side are engaged. Without adjusting, the reel tube 2 can be freely rotated by pulling out the tape 3.

The tape measure configured as described above is used and operates as follows.

In the normal state as shown in FIGS. 1 and 2, the handle base 5 is pushed outward by the action of the coil spring 7, that is, the non-engagement side, and the engagement pin 5 c of the engagement cylinder 5 b in the handle base 5 is engaged. And the engaging recess 4a of the engaging portion 4 of the reel cylinder 2 are not engaged with each other.

Therefore, the reel cylinder 2 is in a rotatable state, and when the tape 3 is pulled out by holding it, the reel cylinder 2 rotates and the tape 3 is pulled out. When the tape 3 is pulled out, the handle 6 attached to the handle base 5 does not rotate. Therefore, even if the reel case 1 falls down, the reel cylinder 2 is not prevented from rotating and the tape can be smoothly moved. 3 can be pulled out.

On the other hand, when the tape 3 is wound up, as shown in FIG. 3, the handle base 5 is operated to be rotated while being pushed so that the engagement pin 5 c of the engagement cylinder 5 b is engaged with the engagement part 4 of the reel cylinder 2. To engage with the engaging recess 4a. In this state, the handle base 5 and the reel cylinder 2 are connected via the engaging portion 4 and the engaging cylinder 5b, and the reel cylinder 2 is rotated while the handle 6 is rotated / operated, so that the tape 3 is transferred to the reel cylinder 2. Can be rolled up.

After the winding is completed, if the handle 6 is slightly turned in the opposite direction, the engaging pin 5c is disengaged from the engaging recess 4a, and the handle base 5 is projected outward by the action of the coil spring 7. Return to the state.

Other spring means may be used for the coil spring 7, and other engaging means may be used for the engaging recess 4a and the engaging pin 5c.
