Description

The present invention relates to a convex hook that is detachably attached to the convex.

Conventionally, so-called convexes have been widely used as tape measures for work, for example, at construction sites and surveying sites.
Since such convexes are often used at work sites, they are housed in the worker's waist bag or pocket of work clothes, and the worker takes out the convex from the waist bag or pocket when using the convex. I'm using it.

By the way, since other tools and the like are also housed in such a waist bag and pocket, the worker searches for the convex in the waist bag and pocket by hand and takes it out.
Therefore, it takes time to take out the convex, and when the convex is taken out, other tools may be taken out together with the convex.

On the other hand, a convex having a spring belt clip on the side surface of the convex body is also commercially available.
When the convex with a belt clip is not in use, the worker can carry the convex by inserting the belt clip into the waist belt of his work clothes.

However, in the method of inserting the belt clip into the waist belt of the worker, the belt clip may come off the waist belt and the convex may fall.

In addition, the convex itself is equipped with a mounting device that can be fixed to the waist belt of the worker with one touch, and the convex with a mounting device that allows the convex to be attached to the waist belt with one touch when not in use is also commercially available. ing.

Such mounting equipment is provided as an accessory to the commercially available convex itself, and in many cases, only the mounting equipment is not sold separately, and since the specifications differ depending on the manufacturer of the convex, it is mounted on a convex made by another company. I couldn't. Therefore, if the convex is broken or damaged, if the convex is replaced with a new one, the mounting device attached to the original convex cannot be used, and it is necessary to purchase the convex with the mounting device.
Furthermore, if the fixture itself breaks down or is damaged, it may not be possible to purchase only the fixture, and it may be necessary to purchase a new convex.

Further, as shown in Patent Document 1, a convex having a carabiner fixed to a cantilever clip (corresponding to a belt clip) of the convex is also commercially available.
According to this convex, the carabiner can be easily and surely attached to and detachably attached to the waist belt of the worker or the like.
However, in a convex provided with such a carabiner, the carabiner itself is fixed to the main body of the convex, and it is difficult to attach the carabiner to another (particularly another company's) convex.

On the other hand, Patent Document 2 includes a convex body and a ring-shaped hanger that can be attached to and detached from a belt clip (claw portion) attached to the convex body.
According to this convex, by attaching a hanger to a commercially available convex with a belt clip, it can be easily and inexpensively configured.

Special Table 2018-509588 Gazette Utility Model Registration No. 3152684 Gazette

However, in the convex according to Patent Document 2, since the hanger is formed in a ring shape and does not have an opening, the tool hook of the other party for suspending the hanger can be opened, for example, a carabiner-shaped tool hook. It will be limited.

Further, in the convex according to Patent Document 2, the portion of the hanger on the belt clip side is provided with a straight portion slightly longer than the width of the belt clip so that the hanger does not shift laterally with respect to the belt clip. In convex sold by manufacturers, the width of the belt clip is also various, and if the length of the straight part of the hanger mentioned above is larger than the width of the belt clip, the hanger will move laterally and rattling will occur. At the same time, if the length of the straight portion of the hanger is smaller than the belt clip, the hanger cannot be attached to the belt clip.

In view of the above points, it is an object of the present invention to provide a convex hook that can be detachably attached to various convex with belt clips.

According to the configuration of the present invention, the above object is a convex hook that can be detachably attached to a convex having a belt clip made of a leaf spring on the side surface, and is composed of a main body formed flat as a whole. A hook part is provided at one end in the longitudinal direction of the main body, and an engaging part is provided at the other end. It is composed of a gate bar that is supported and urged outward to close the opening at the closed position, and the engaging portion engages with an engaging hole provided inside the outer periphery of the other end. It is composed of a holding portion that crosses the hole in the lateral direction, and the belt clip of the convex is inserted into the engaging hole, and the holding portion is sandwiched so that the main body is fixedly held to the side surface of the convex. Achieved by the convex hook, which is characterized by.

According to the above configuration, the main body is aligned with the side surface to which the convex belt clip is attached, the belt clip is inserted into the engaging portion, the pinching portion is fitted into the opening of the belt clip, and the pinching portion is pushed into the opening of the belt clip. Therefore, the sandwiched portion can be sandwiched by the belt clip and fixedly held.

As a result, the convex hook is fixedly held to the belt clip without rattling.
From this state, the hook portion provided at one end of the convex hook can be easily attached to and detached from the mounting bracket such as the worker's waist belt to the mounting bracket such as the worker's waist belt. Can be.

Then, in a state where the hook portion is attached to the mounting bracket such as the waist belt of the worker, the convex body is hung from the mounting bracket such as the waist belt. Therefore, even if the convex body hits something when the worker moves, the convex body swings around the hook part, and the impact on the convex body is softened, so that the convex body is damaged. Will be reduced.

When removing the convex hook from the convex belt clip, the holding force of the belt clip is pushed by pushing the main body against the belt clip and the convex so that the holding portion escapes from the opening of the belt clip. The convex hook can be easily removed from the convex belt clip by disengaging from the opening and detaching the convex belt clip from the engagement hole.

In this way, the convex hook can be detachably attached to the belt clip of any manufacturer as long as it is a convex with a belt clip.

The convex hook according to the present invention preferably has a hook body having an open portion on one side and a hook body that is swingably supported inward so as to close the open portion and is urged outward to close. It is characterized by being composed of a gate bar that closes the opening at a position.
According to this configuration, the hook portion provided at one end of the hook for the convex is attached to the mounting bracket such as the waist belt of the worker while opening the gate bar, so that the convex can be easily attached to the worker. It can be detachably attached to a mounting bracket such as a waist belt.

The convex hook according to the present invention is preferably characterized in that the sandwiching portion is formed so as to be inclined so as to be thin toward the other end.
According to this configuration, when the convex hook is attached to the convex belt clip, the inclined portion of the holding portion abuts on the inner surface of the belt clip, and this contact causes the holding portion to abut against the belt clip. It can be reliably held without rattling.

The convex hook according to the present invention is preferably at least one set in which the holding portion is formed so as to be gradually thinned from both sides to the inside in the lateral direction corresponding to a plurality of types of belt clips having different widths. It is characterized by having a step portion.
According to this configuration, when the holding portion holds the convex belt clip, the belt clip is held by the inner edge of the engaging hole or any step portion in the lateral direction, so that the belt clip is securely held in the lateral direction. Therefore, the hook for this convex can reduce the lateral rattling with respect to the belt clip of the convex.

The convex hook according to the present invention is preferably made of a glass fiber reinforced resin.

According to this configuration, since the hook for this convex is extremely lightweight and tough, it is possible to withstand the weight of a relatively heavy convex body and to the convex body. With the convex hook attached, the additional weight is small.

In this way, according to the present invention, since it can be attached to the convex without rattling by a simple configuration, it can be used as if the convex itself is attached with a hook that can be opened and closed. As a result, it is possible to hook and carry any ring-shaped object such as a belt loop, a waist belt D-ring or loop, or a ring-shaped tool hook (tool holder) that could not be hooked until now. In addition, it is easy to remove and can be used immediately when you want to use it. Such features can be provided for almost all commercially available convexes with belt clips.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
1 to 5 show the configuration of one embodiment of the convex hook according to the present invention.
1 to 5, the convex hook 10 has a main body 11 formed so as to be flat and extend in the longitudinal direction (vertical direction in FIG. 1) as a whole, and one end 11a of the main body 11 (in FIG. 1). It is composed of a hook portion 20 provided at the upper end) and an engaging portion 30 provided at the other end 11b (lower end in FIG. 1).

The hook portion 20 includes a hook main body 21 formed in an annular shape along the outer peripheral edge of the main body 11, an open portion 22 provided on one side (right side in FIG. 1) of the hook main body 21, and an open portion 22. It is composed of a gate bar 23 that is swingably supported inward so as to close the gate bar 23.
The hook body 21 is formed of, for example, a glass fiber reinforced resin, and is made tough and lightweight.
The gate bar 23 is supported on the lower side of the open portion 22 so as to be swingable inward as shown by an arrow A in FIG.

Specifically, the gate bar 23 is made of, for example, a single elongated rod-shaped material having a spring property, is bent so as to extend in the same direction from the central portion 23a as shown in FIGS. 1 and 2, and both ends 23a, The 23b is bent at a substantially right angle so as to face each other inward, and is inserted into the through holes 11c and 11d from both sides of the main body 11, respectively.
Here, the two through holes 11c and 11d are separated from each other in the longitudinal direction, and one through hole 11c is displaced upward and slightly inward in FIG. 1 with respect to the other through hole 11d. It is provided.

As a result, the gate bar 23 can swing in the direction of arrow A from the closed position shown in the figure, and elasticity acts in the direction opposite to the arrow A to urge the gate bar 23 toward the closed position.

The main body 11 is provided with a recess 11e on the side edge opposite to the gate bar 23 in FIG. 1, and when an operator pushes the gate bar 23 inward, for example, with a thumb, a pointing finger or the like is pressed. By locating it in the recess 11e, the gate bar 23 can be opened in a stable state.

In this way, the hook portion 20 is configured in the same manner as a general gate bar type hook, and the gate bar 23 is opened and passed through an annular or annular portion such as a D ring, for example. By releasing the hand from the gate bar 23, the opening portion 22 may be closed, and the hook portion 20 and the convex hook 10 may be suspended.

The engaging portion 30 crosses the engaging hole 31 having the outer peripheral edge of the main body 11 as a frame and the engaging hole 31 in the lateral direction (left-right direction in FIG. 1) on the other end 11b side of the main body 11. It is composed of a formed holding portion 32 and.
As a result, the engaging hole 31 is divided into two engaging holes 31a and 31b by the holding portion 32.
The engagement hole 31a is located on one end 11a side (upper side in FIG. 1) closer to the hook portion 20, and the engagement hole 31b is located on the other end 11b side (lower side in FIG. 1).

The sandwiching portion 32 has a substantially circular cross section and is provided with two sets of stepped portions 32a and 32b on both sides in the lateral direction.
Here, the sandwiching portion 32 is selected to have a thickness (in the direction perpendicular to the paper surface in FIG. 1 and in the left-right direction in FIG. 2) so that the belt clip attached to the convex can pass through.

The first set of stepped portions 32a project laterally inward from both side edges of the engaging holes 31b by a predetermined distance d1, and gradually become thinner from the holding portion 32 toward the other end 11b of the main body 11. It is formed so as to be inclined.
Further, the step portion 32b of the second set projects laterally inward from the step portion 32a of the first set by a predetermined distance d2, and is gradually thinned from the sandwiching portion 32 toward the other end 11b of the main body 11. It is formed so as to be inclined.

Further, the sandwiching portion 32 is provided with, for example, a spindle-shaped cross section so as to gradually taper toward the other end side 11b of the main body 11 on the laterally inner side of the second set of step portions 32b.
As shown in FIG. 6, the lower ends of the first set of step portions 32a, the second set of step portions 32b, and the holding portion 32 are formed so that the distances in the longitudinal direction are sequentially shortened.

Here, in the engagement hole 31b of the engagement portion 30, the gaps D1, D2 and D3 defined between the inner wall of the engagement hole 31b, the first set of step portions 32a and the second set of step portions 32b. Are selected according to the width of the belt clip in a general convex with a belt clip.

That is, the gap D1 corresponds to the width of the small belt clip, the gap D2 corresponds to the width of the medium-sized belt clip, and the gap D3 corresponds to the width of the large belt clip.
In this way, by setting the three-stage gaps D1, D2 and D3, it is possible to correspond to belt clips of various sizes.
As shown in FIGS. 1 and 4, the first set of step portions 32a and the second set of step portions 32b are formed so as to wrap around the opposite side of the sandwiching portion 32 (one end 11a side of the main body 11), respectively. Has been done.

The convex hook 10 according to the present invention is configured as described above. For example, when the hook 10 is attached to a convex 40 provided with a medium-sized leaf spring belt clip, the tip of the belt clip 41 of the convex 40 is first lifted (convex 40). The tip of the belt clip 41 is inserted into the engaging hole 31a of the engaging portion 30 of the convex hook 10 from the back side (left side in FIG. 5), and the belt clip 41 is inserted into the convex hook 10. On the other hand, it is relatively pushed toward the other end 11b side of the main body 11 in the longitudinal direction.

As a result, the tip of the belt clip 41 slides on the slope of the second set of stepped portions 32b, and the root portion of the belt clip 41 comes into contact with one end 11a side of the main body 11 of the holding portion 32, as shown in FIG. In addition, the belt clip 41 sandwiches and holds the sandwiching portion 32 from the front surface and the back surface.

In this state, as shown by the alternate long and short dash line in FIG. 7, the lateral edges of the belt clip 41 are sandwiched by the inner side surface of the first step portion 32a of the engaging portion 32. Since it is sandwiched and held in the axial direction, the convex hook 10 can be reliably held with respect to the convex 40 with a belt clip without rattling. FIG. 8 shows a state in which the convex hook 10 is attached to the convex 40.

In the convex 40 with a belt clip to which the convex hook 10 is attached in this way, the hook portion 20 of the convex hook 10 is, for example, as shown in FIG. 9, such as a D ring provided on the waist belt of a worker. By being passed through the annular mounting bracket, it can be easily and detachably hung from the worker's waist belt or the like.

When the convex hook 10 is removed from the convex 40 with a belt clip, the belt clip 41 is pushed toward one end 11a of the main body 11 relative to the convex hook 10 from the states shown in FIGS. 6 and 7.

As a result, both side edges of the belt clip 41 slide along the slope of the first set of stepped portions 32a, and the tip of the belt clip 41 is lifted accordingly, so that the tip of the belt clip 41 can easily hold the holding portion 32. It will be retracted into the engaging hole 31a beyond the above, and will be disengaged from the holding portion 32.

In the case of a convex with a large belt clip, the belt clip 41a similarly sandwiches the sandwiching portion 32 from the front surface and the back surface, and is sandwiched by the inner surface thereof in the engagement hole 31b as shown in FIG. .. As a result, even in the case of a large belt clip, rattling in the lateral direction is reduced.

On the other hand, in the case of a convex with a small belt clip, the belt clip 41b similarly sandwiches the sandwiching portion 32 from the front surface and the back surface, and as shown in FIG. 7, the second band clip 41b is formed in the engaging hole 31b. It is sandwiched by the inner side surface of the step portion 32b of the set. As a result, even in the case of a small belt clip, rattling in the lateral direction is reduced.

It should be noted that FIG. 10 shows a six-view drawing so that the overall configuration of the convex hook according to the above-described embodiment of the present invention is clarified. That is, FIG. 10A is a plan view of the convex hook, FIG. 10B is a front view of the convex hook, and FIG. 10C is a bottom view of the convex hook. 10 (d) is a left side view of the convex hook, and FIG. 10 (e) is a right side view of the convex hook. FIG. 10 (f) is a rear view of the convex hook.

The present invention can be implemented in various forms without departing from the spirit of the present invention.
For example, in the above-described embodiment, the main body 11 is provided with the recess 11e, but the present invention is not limited to this, and the recess 11e may be omitted.
Further, in the above-described embodiment, it is clear that the hook portion 20 may be configured as, for example, a carabiner-shaped hook portion without being limited to such a configuration.
