This application is a National Stage Patent Application of PCT International Patent Application No. PCT/KR2019/015341 (filed on Nov. 12, 2019) under 35 U.S.C. § 371, which claims priority to Korean Patent Application Nos. 10-2018-0142238 (filed on Nov. 19, 2018) and 10-2019-0136190 (filed on Oct. 30, 2019), which are all hereby incorporated by reference in their entirety.

BACKGROUND

The present disclosure relates to a belt holder and, more particularly, to a belt holder for a tape measure, that is mounted on a belt to hold a tape measure by hanging the tape measure.

A tape measure enables a worker to easily measure a distance longer than the worker's arms and is very convenient to carry, so tape measures are generally used in construction sites.

Since tape measures are frequently used in construction sites, they are hung on a belt to be carried. Tape measures have a belt clip to be able to be easily carried in this way.

A common belt holder for a tape measure has a type in which a holder body that is mounted on a belt and a mount that has a clip hole being open up and down, in which the belt clip of a tape measure is inserted, to hang the tape measure are integrated. When a worker mounts a tape measure by hanging the belt clip of the tape measure on the mount of such a common belt holder for a tape measure, the worker can freely use both hands and can conveniently separate and use the tape measure from a belt at any time if the tape measure is needed.

However, when a tape measure is mounted using such a common belt holder for a tape measure, there is a problem that the tape measure is easily separated from the belt holder for a belt when the worker excessively moves.

Meanwhile, as a completely different type from the common belt holder for a tape measure, a specific type of belt holder for a tape measure which locks a tape measure when the tape measure is inserted in the belt holders and prevents separation of the tape measure unless a specific unlocking device is operated has been frequently developed and sold.

Since when a user only mounts a tape measure on the specific type of belt holder for a tape measure, the tape measure is maintained in the locked state, thus there is an advantage that a tape measure is not separated from the belt holder even though the user excessively moves or an external force is applied.

However, the specific type of belt holder for a tape measure has a problem that it is troublesome to have to unlock a tape measure by operating the locking device even though performing work not having the possibility of causing separation of the tape measure and a tape measure has to be equipped with an exclusive bracket suitable for the specific type of belt holder for a tape measure.

SUMMARY

The present disclosure has been made in an effort to solve the problems of the related art and an objective of the present disclosure is to provide a belt holder for a tape measure that can easily mount tape measures having a belt clip of the related art and enables selective use of a mounting mode in which a tape measure can be easily mounted and separated even without specific operation and a locking mode in which a tape measure is not separated without specific operation.

In order to achieve the objectives, a belt holder for a tape measure which is mounted on a belt to hold the tape measure having a belt clip by hanging the tape measure includes: a holder body configured to be mounted on the belt; a rotary mount having a clip hole formed in an up-down direction in which the belt clip of the tape measure is inserted to hang the tape measure, rotatably coupled to a front surface of the holder body, and being able to change into a posture for a mounting mode in which the rotary mount is vertically upright with respect to the holder body and a posture for a locking mode in which the rotary mount is rotated from the posture for the mounting mode; a locking bracket having a locking jaw preventing separation of the belt clip from the clip hole, and provided at the holder body or the rotary mount such that the locking jaw can reciprocate between a position where the locking jaw prevents separation of the belt clip and a position where the locking jaw does not prevent separation of the belt clip; and a restoring spring elastically supporting the locking bracket in one direction such that the locking jaw of the locking bracket is positioned at the position where the locking jaw prevents separation of the belt clip and the position where the locking jaw does not prevent separation of the belt clip, in which the belt holder can be used in the mounting mode in which the rotary mount is in the posture for the mounting mode and the belt clip of the tape measure can be inserted into the clip hole or can be freely taken out of the clip hole and in the locking mode in which the rotary mount is in the posture for the locking mode and the locking jaw is positioned over the clip hole.

The locking bracket may be rotatably disposed at the rotary mount; the restoring spring may elastically support the locking bracket such that the locking jaw of the locking bracket is positioned at the position where the locking jaw does not prevent separation of the belt clip; and a locking bracket rotation portion rotating the locking bracket such that the locking jaw of the locking bracket is moved to the position where the locking jaw prevents separation of the belt clip when the rotary mount is changed into the posture for the locking mode from the posture for the mounting mode may be further provided.

The locking bracket may have a locking bracket body having a first side where the locking jaw is formed and another side rotatably coupled to the rotary mount, and a sliding protrusion protruding toward the holder body from the locking bracket body; the locking bracket rotation portion may be a guide slope formed at the holder body, extending along a movement path of the sliding protrusion when the rotary mount is changed into the posture for the locking mode from the posture for the mounting mode, and protruding at a slope toward the sliding protrusion; and the sliding protrusion of the locking bracket may keep in contact with the guide slope by the restoring spring.

A locking bracket hole for inward and outward movement of the locking bracket may be formed over the clip hole of the rotary mount; and the locking bracket may be positioned inside the rotary mount without protruding outward in the mounting mode, and the locking jaw of the locking bracket may protrude through the locking bracket hole and is positioned over the clip hole in the locking mode.

The holder body and the rotary mount may be combined to be able to rotate about a rotary shaft positioned at centers of the holder body and the rotary mount; the rotary mount may have a posture-fixing plate spring having an end fixed to the rotary mount and another end where a locking protrusion is formed; and the holder body may have a posture-fixing plate spring stopper formed in cylindrical shape surrounding the rotary shaft and having, on an outer surface thereof, a first locking groove in which the locking protrusion is inserted to elastically fix the rotary mount to the holder body when the rotary mount is in the posture for the mounting mode, a second locking groove in which the locking protrusion is inserted to elastically fix the rotary mount to the holder body when the rotary mount is in the posture for the locking mode, and a locking protrusion guide surface extending between the first locking groove and the second locking groove to guide movement of the locking protrusion.

A first anti-rotation step restricting movement of the locking protrusion may be formed opposite to the locking protrusion guide surface of the first locking groove, and a second anti-rotation step restricting movement of the locking protrusion may be formed opposite to the locking protrusion guide surface of the second locking groove.

The locking bracket may be slidably disposed on the holder body and the restoring spring may elastically support the locking bracket in one direction such that the locking jaw of the locking bracket is positioned at the position where the locking jaw prevents separation of the belt clip.

The holder body may further have a releaser sliding the locking bracket to the position where the locking jaw of the locking bracket does not prevent separation of the belt clip.

Any one of the holder body and the rotary mount may have a spring protrusion and the other one of the holder body and the rotary mount may have a plurality of protrusion grooves in which the spring protrusion is inserted to elastically fix the rotary mount in the posture for the mounting mode or the posture for the locking mode.

A pair of clip fixing plate springs for holding and fixing left and right sides of the belt clip inserted in the clip hole may be further disposed in the rotary mount.

The belt holder for a tape measure of the present disclosure can be selectively used in the mounting mode in which a user can vertically erect the rotary mount and then insert the belt clip of the tape measure into the clip hole or take the belt clip of the tape measure out of the clip hole at any time and the locking mode in which the user can rotate the rotary mount from the vertical state such that the tape measure is locked to the belt holder for the tape measure and the belt clip of the tape measure cannot be separated from the rotary mount.

That is, it is possible to simply mount and easily separate and use a tape measure without specific operation when performing simple work without a possibility of separation of the tape measure and it is possible to safely carry the tape measure by mounting the tape measure in the locked state when performing difficult work with a possibility of separation of the tape measure.

Further, according to the present disclosure, unlike specific types of belt holders for a tape measure of the related art, it is possible to easily mount tape measures as long as the tape measures have common belt clips of the related art.
