Description

  The present invention relates to a tape measure provided with a belt clip for attaching the tape measure to an operator's belt.

  Conventionally, as shown in FIG. 5, a belt clip provided on a tape measure is fixed to a case 15 with a single fixing screw 14, and a screw portion of the fixing screw (male screw) is a rotating drum erected in the case. A support shaft is screwed into a female screw portion provided in the axial direction (see, for example, Patent Document 1).

  As mentioned above, the belt clip is fixed with one fixing screw, so when an impact is applied to the belt clip in the direction of loosening the fixing screw due to collision or dropping of the case during work, the belt clip moves and is fixed by this impact. When the screw is loosened, the belt clip is dropped, or when the tape measure is attached to the operator's belt, the tape measure may fall.

  And when the tape measure falls during work on the ground, it can be said that the probability of occurrence of secondary disasters related to humans is extremely low, but when the tape measure falls during work at high altitude, the human body is of course Although it was expected that a very serious secondary disaster would occur, there has been no secondary disaster so far, and measures have been taken for reasons such as handling of the tape measure and the reasons described below. It was not taken.

  The reason why the belt clip is fixed with one fixing screw is that the case can be stably held when the center of the belt clip is located approximately at the center of the case. Therefore, when fixing the belt clip to this position, the fixing screw is screwed in. Since the only member that can be used is a shaft for supporting the rotating drum, a female screw is threaded in the axial direction of the shaft, and a fixing screw (male screw) is screwed into the female screw portion. Further, since this shaft is configured to correspond to the rotating drum, the female screw portion can be provided only at one place on the shaft end surface.

  Although fixing by bonding is also conceivable, the adhesive cannot obtain the expected adhesive force unless it is properly managed and stored and used, and there is a risk that the belt clip may suddenly fall out of the case. When a two-component mixed adhesive that can be obtained is used, the adhesive is not used because the storage and use environment must be managed more strictly. Moreover, the combined use of the adhesive and the fixing screw cannot be used together because the case may be opened for mechanical adjustment after the tape measure is assembled.

  However, even if the belt clip is fixed with one fixing screw, there has never been a secondary disaster, but it cannot be said that a secondary disaster will never occur in the future. In order to improve it, measures to secure and fix the belt clip were an indispensable issue.

  An object of the present invention is to provide a tape measure in which a belt clip can be stably fixed to a case with a plurality of fixing screws without deteriorating the handleability of the tape measure.

  In order to solve the above-described problems, a tape measure according to the present invention is a tape measure provided with a belt clip that is engaged with an operator's belt, and the belt clip is fixed to the case with a plurality of fixing screws, and is one of the fixing screws. Is screwed into a screw receiving portion provided on a support shaft of a rotating drum installed from the through hole of the case, and the other fixing screw is screwed into a screw receiving portion formed in the case. It is.

  In the present invention, a belt that is worn by an operator is inserted between the plates of the hairpin-shaped plate body and can be engaged with the belt body, and with the belt body. It is configured so that the case of the tape measure can be attached to an external member, such as a clip body that changes so that it can be hung on a hanging tool such as a carabiner (such as a lever ring or D hook) provided on the belt. All that are called belt clips.

  The belt clip fixed with a plurality of fixing screws has one fixing screw, that is, a first fixing screw as a conventional belt clip fixing screw, a through hole having a base portion disposed on the outer surface of the case in the belt clip, The through hole formed in the case is passed through and screwed into a screw receiving portion formed in the axial direction of a support shaft for rotatably supporting the rotating drum housed in the case. The screw receiving portion is configured such that a first fixing screw can be screwed thereto, and, for example, a female screw is formed.

  The second fixing screw, which is another fixing screw, is screwed into a screw receiving portion formed on the case, and the screw receiving portion is preferably molded integrally when the case is molded. Of course, another member may be attached (fixed) to the case as a screw receiving portion.

  When the screw receiving portion is provided inside the case, at least a portion corresponding to the base portion of the belt clip of the case is protruded outward (a step portion protruding outward is provided on the case), and the side surface of the rotating drum (rotating The space between the surface) and the case inner wall is enlarged, and a screw receiving portion is provided in the enlarged space, for example, on the inner wall of the stepped portion. The screw receiving portion preferably secures at least three threads of the second fixing screw from the result of the screw insertion verification. Of course, four or more peaks may be secured as long as the handling of the tape measure is not hindered.

  Further, in the case where the case itself is used as the screw receiving portion, for example, a step portion protruding outward is provided by increasing the material thickness of the portion corresponding to at least the base portion of the belt clip of the case, and this step portion is used as the second portion. Use the screw receiving part of the fixing screw. And the step part used as a screw receiving part is good to make it the thickness which can ensure the screw thread of a 2nd fixing screw at least 3 threads. In addition, you may make the thickness of a raw material into the thin part suitably in the site | part in which the 2nd fixing screw is not screwed.

  When the step portion is used as the screw receiving portion of the second fixing screw as described above, the base portion of the belt clip is disposed on the step portion, and the rotating drum incorporated in the case is freely rotatable on the step portion. Is provided with a through hole facing the screw receiving portion formed on the support shaft. The through hole is a through hole through which the first fixing screw is passed.

  The screw receiving portion formed on the support shaft of the rotary drum into which the first fixing screw is screwed and the screw receiving portion into which the second fixing screw is screwed are formed in such a manner that the first and second fixing screws have a tape measure. (For example, a tapping screw, a screw that is widely used such as a metric screw, and an inch product for an export product) are selected according to the selected screw.

  According to the tape measure of the present invention, the belt clip can be fixed to the case with a plurality of fixing screws, so that the fixing stability can be remarkably improved and the screw of the newly provided fixing screw (second fixing screw). Since the thread of the receiving portion can be made three threads based on the result of the screw insertion verification, the handleability of the tape measure is not lowered.
