Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tape measure device in which the tape is stored in the case by winding the tape around the outer periphery of a winding drum disposed in the case. This relates to a tape measure tape pull-out ring attached to the tip.

Conventionally, a ring 50 for drawing out a measuring tape as shown in FIG. 1 has been known. This ring 50 is constructed by folding both ends 52 and 53 of a U-shaped frame 51 inward at right angles. Both ends 52 and 53 of the frame 51 are fitted into an annular connecting fitting 55 attached to the tip 54a of the measuring tape 54, which faces the outside through an opening provided on the outer periphery of the case (not shown). There is. That is,
The ring 50 having the above-mentioned configuration has the above-mentioned connecting fitting 55
It is rotatable 360° about a hinge portion 56 formed by the frame body 51 and both ends 52 and 53 of the frame body 51 as a fulcrum.

By the way, when the ring 50 is attached to the tip 54a of the measuring tape 54 as described above,
When the tape 54 is completely housed in the case, the ring 50 is left rotatable without being positioned on the outer periphery of the case. In this way, when storing the tape measure tape, if the ring 50 is left hanging around outside the case, other members may get caught on the ring 50 and pull out the tape measure tape 54. This is not suitable for a case-storage type tape measure device, which has the advantage of being able to store and store the tape measure tape 54 entirely in a case when the tape measure is not used.

Therefore, in order to solve the above-mentioned drawbacks, a ring for pulling out a tape measure tape is press-fitted into the outer peripheral wall of a plastic case using the elasticity of the case, or a ring for pulling out a tape measure tape is attached to a tape measure tape. It has been proposed that the ring be press-fitted and held in a part of the case by utilizing the elasticity of the connecting fitting, but these require means for press-fitting the ring into the case, which is time-consuming.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned conventional drawbacks, and provides a novel tape measure tape drawer ring that enables positioning of the tape measure drawer ring in a case when the tape measure tape is stored. The purpose is to

Another object of the present invention is to automatically position the tape measure tape in the case at the same time that the tape measure tape is stored in the case without press-fitting the ring for drawing out the tape measure tape into the case.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

FIG. 2 is a perspective view showing the tape measure device according to the present invention being held by hand.

This tape measure device 1 includes a tape measure storage case 5 in which a front cover 2 and a back cover 3 are assembled with screws (not shown), a winding drum 7 for winding a tape measure tape 6 into the case 5, and this drum. 7 and a handle 8 for rotational operation. Incidentally, the case 5, the winding drum 7, and the handle 8 are individually integrally formed of ABS resin.

The handle 8 can be raised and lowered with respect to one end surface 13 of the drum 7 using the base end 8a as a fulcrum, and when raised as shown in FIG. The axial direction of the handle 9 is set parallel to the axial direction of the drum 7, and the circular movement of the knob 9 ensures smooth rotation of the handle 8 when the handle 8 is rotated. Furthermore, by pushing the handle 8 down onto the drum 7 using the base end 8a as a fulcrum, the handle 8 can be stored in a concave groove 10 formed in one end surface 13 of the drum 7. At this time, the knob 9 is inserted into the case 5 through an opening 11 formed in the bottom wall 10a within the concave groove 10.

On the other hand, a concave notch 12 is provided in the outer circumferential portion 5a of the case 5 to accommodate a measuring tape pull-out ring 15, which will be described later.

A bottom wall 12a of the notch 12 is formed into an arched shape, and an opening 14 from which the measuring tape 6 is pulled out is provided in the bottom wall 12a. At the tip 6a of the tape measure tape 6 pulled out from this opening 14, there is a ring 15 for drawing out the tape measure tape.
is installed.

As shown in FIG. 3, the ring 15 is formed into a rectangular closed loop, and the entire ring 15 is curved to form an arch shape. And the above ring 1
A measuring tape mounting shaft 1 is provided on the inner circumferential wall 15a of No.
6,17.

Then, attach the mounting shafts 16 and 17 to the tape measure tape 6.
The ring 15 is attached to the tip 6a of the measuring tape 6 by fitting it into an annular connecting fitting 18 attached to the tip 6a. The mounting shafts 16 and 17 and the connecting fitting 18 constitute a hinge portion 19, and the ring 15
is a state in which one side surface 15A on the proximal end side of the ring 15 is in contact with one side surface 6A on the measuring tape 6 with the hinge portion 19 as a fulcrum, and one side surface 1 on the distal side side of the ring 15
5B is in contact with the other side surface 6B of the measuring tape 6, and is rotatable within a range of about 180 degrees.

Next, the operation of the measuring tape drawer ring 15 having the above structure will be explained with reference to FIGS. 4A, 4B and 4C.

As shown in FIG. 4A, the handle 8 is rotated, and the tape measure tape 6 that has been pulled out is inserted into the opening 14 provided in the bottom wall 12a of the concave notch 12.
It is wound around the outer periphery of the winding drum via the winding drum. Then, as shown in FIG. 4B, when the proximal edge 20 of the measuring tape pull-out ring 15 comes into contact with the bottom wall 12a of the notch 12, the ring 15 moves to the hinge part 19.
It pivots as shown by the arrow in FIG. 4B using the fulcrum as the fulcrum. Then, the measuring tape 6 is further taken up on the winding drum 7.
As the ring 15 is wound around the outer periphery, the proximal edge 20 of the ring 15 moves toward the lower end 21 of the notch 12 while following the bottom wall 12a. In this way, the ring 15 has a proximal edge 20 serving as one end thereof.
When the ring comes into contact with the bottom wall 12a of the notch 12, the ring pivots about the hinge 19 as a fulcrum, and the entire ring automatically fits into the notch 12 as shown in FIG. 4C. It is positioned at the outer peripheral portion 5a of No.5.

As described above, according to the present invention, the tape measure tape drawer ring is not left hanging around outside the case when the tape measure tape is stored, and is automatically returned to the predetermined position in the case as soon as the tape measure tape is stored. Can be positioned. Therefore, it is possible to reliably prevent an accident in which the tape measure is accidentally hooked on the ring for pulling out the tape measure tape when the tape measure is not in use and the tape measure tape is pulled out.
