Description of the Related Art Conventionally, a band clamp, such as a band clamp 501 shown in a perspective view of FIG. 31, has been used as a band clamp for winding and tightening an object such as a harness or a plurality of rod-shaped members such as a car with a band. There was something. In the following description, in FIG.
The insertion direction) is referred to as the front (front) side, and in the following figures, the upper side is indicated as UP, the front side as FRONT, and the left side as LEFT. FIG. 30 shows that the band 502 is
FIG. 5 is a front view of the band clamp 501 in a state where the band clamp 501 is detached from the device. The band clamp 501 is entirely made of flexible polypropylene (PP).
0, a lock portion 503 is formed in a tubular shape to form a tunnel portion 531. One end of a bendable band 502 is integrally formed at a predetermined position of the lock portion 503 as shown in FIG. The other end is inserted into the tunnel portion 531 and fixed at a predetermined position. Here, FIG.
It is sectional drawing in the AA part of 0. FIG. 29 and FIG.
As shown in FIG. 0, a lock claw 505 is provided in the tunnel portion 531. Then, as shown in FIG. 29, the base 553 of the lock claw 505 is integrally formed upward at the rear end of the lower wall surface of the tunnel portion 531, and is curved and substantially horizontally to the front. It is extended in a shape. On the upper surface of the lock claw 505, a plurality of meshing portions 551 are cut in parallel in a groove shape in the band width direction so as to have a saw-like cross section. At the front end of the lock claw 505, a lock release claw 552 formed to be thin is protruded in a claw shape toward the front. Since the base 553 of the lock claw 505 is made of flexible PP, the lock claw 505 is
3 can be swung up and down around the center of rotation.

FIGS. 23 to 28 are cross-sectional views showing a process of inserting the tip 521 of the band 502 into the lock portion 503. As shown in FIG. 23, a flexible band 502 made of PP is bent as shown in FIG. 31 and its tip 521 is inserted into the opening of the tunnel portion 531. At this time, as shown in FIG. 30, the tip portion 521 is tapered, so that it can be easily inserted into the opening of the tunnel portion 531. As shown in FIG. 23, the rear surface of the base portion 553 of the lock claw 505 is formed to be smoothly curved toward the front side, so that the tip portion 521 of the band 502 inserted into the tunnel portion 531 Even if it is slightly displaced downward at the time of insertion, it is guided by the base 553 and comes into contact with the upper wall surface of the tunnel portion 531 as shown in FIG. At this time, as shown in FIG. 23, the thickness d1 of the tip 521 of the band 502 is

8 in the direction opposite to the arrow shown in FIG.
5 is displaced downward, the engaging groove 522 of the band 502 and the engagement portion 551 of the lock claw 505 release the engagement, and the state where the lock release claw 552 is displaced downward with a fingertip or the like is maintained. It is moved rearward (in the direction opposite to the arrow shown in FIG. 28) and detaches from the lock portion 503. In this way, the once bound object can be released from the band clamp 501.

[0005]

However, the conventional band clamp 501 requires the following in order to restrain an object.
As shown in FIG. 23, the tunnel part 5 of the lock part 503 must be used.
The end portion 521 of the band 502 must be inserted from 31 and if the band is longer than necessary, there is a problem that the work of removing and inserting the band 502 becomes complicated one by one. Further, even if the length of the band 502 is appropriate, the band 502 may be attached to the tunnel portion 531 of the lock portion 503, for example, in a narrow place inside the engine room.
There is a problem that the operation of inserting the tip 521 is very difficult. In addition, the target object is
28, the lock release claw 552 provided at the front end of the lock claw 505 is pulled down with a fingertip or the like, and the lock claw 505 is displaced downward as shown in FIG. And lock claw 50
5 must be disengaged from the lock portion 503 by releasing the engagement of the meshing portion 551 of FIG. 5 and moving the band 502 backward while maintaining the state where the unlocking claw 552 is displaced downward with a fingertip or the like. While maintaining the state in which the unlocking claw 552 is displaced downward with a fingertip or the like,
There was a problem that the operation of detaching 2 was a complicated operation. In particular, since the lock release claw 552 is located behind the band 502, it is difficult to operate the lock claw 552 in position. For this reason, for example, there is a problem that the work is difficult when the work is performed in a narrow space at the back of the engine room. further,
Since the unlocking claw 552 is located behind the band 502 and cannot be viewed, it is sufficient that the presence and the position of the unlocking claw 552 be known in advance. There was a problem that the work was difficult due to the groping work. Furthermore, for those who handle this band clamp 501 for the first time, the release becomes impossible because the release method is not understood at first glance,
There is a problem that the band clamp 501 may be destroyed in an attempt to release it forcibly, and there is a problem that the serviceability is extremely poor.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a band clamp which can easily bind and release an object and has high serviceability.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A band clamp according to the present invention will be described below with reference to the accompanying drawings, using a band clamp 1 as a preferred embodiment. First, the outline of the configuration of the band clamp 1 will be described.

FIG. 1 is a perspective view of the band clamp 1 in a closed state. FIG. 2 is a perspective view of the band clamp 1 in an opened state. The band clamp 1 is entirely made of flexible polypropylene (PP). The material is not limited to PP, and a polymer resin having flexibility having appropriate elasticity and durability at the hinge portion is preferable, and a material such as polyamide resin can be used. As shown in FIG.
The lock portion 3 is formed in a tubular shape to form a tunnel portion 31, and the lock portion 3 is formed of PP so that one end of the bendable band 2 protrudes downward from a lower rear portion of the lower surface of the lock portion 3. It is formed integrally. Then, the other end of the band 2 is inserted into the tunnel portion 31 and fixed to a predetermined position of the lock portion 3.

FIG. 3 is a front view of the band clamp 1 in a state where the band 2 is detached from the lock portion 3. FIG.
FIG. 4 is a side view as viewed from a direction C in FIG. 3. FIG.
FIG. 4 is a sectional view taken along a line BB in FIG. 3. As shown in FIGS. 2 and 3, a lock claw 5 is provided in the tunnel portion 31 of the lock portion 3. Then, as shown in FIG. 5, the base 53 of the lock claw 5 is integrally formed upward at the rear end of the lower surface 31 b of the tunnel portion 31. It is curved and extends substantially horizontally in a tongue shape toward the front. A plurality of grooves are formed in the upper surface of the lock claw 5 in parallel in the left-right direction so as to have a saw-like cross section.
1 is provided. The meshing portion 51 has three rows of a vertical surface 51b, which is a surface substantially perpendicular to the direction in which the lock claw 5 extends, and a slope 51a, which is a surface inclined approximately 60 degrees downward and forward from the vertical surface 51b. Is provided. Since the base 53 of the lock claw 5 is made of flexible PP, the lock claw 5 can swing up and down around the vicinity of the base 53 as a center of rotation.

As shown in FIGS. 4 and 5, the band 2
The lock portion 3 is integrally formed so as to protrude downward from the rear portion of the lower surface. The length is appropriately selected depending on the object to be bound. The entire band 2 has a belt-like shape, and a hook groove 22 is formed on the rear side. The hanging groove 22 is formed by engraving a groove in the width direction of the band 2, a plurality of hanging grooves 22 are provided in parallel, and a saw-like shape is formed in a side view. One hanging groove 22
Is formed by a vertical surface 22b which is a surface substantially perpendicular to the longitudinal direction of the band, and a slope 22a which is a surface inclined about 60 degrees to the rear side of the vertical surface 22b. A large number 22 are provided in parallel with each other.
The hanging groove 22 is not provided in the base portion 23 and the distal end portion 21 fixed to the lock portion 3. As a result, the thickness of the band 2 is reduced in the portion where the hanging groove 22 is formed, so that the flexibility of the band 2 itself is increased and there is an effect that the band 2 is easily curved. Of course, depending on the thickness and width of the band 2, the hook groove 22 may be provided from the front end 21 to the base 23. Further, the shape of the engaging groove 22 is determined by the engagement portion 51.
It is only necessary to engage and lock at an arbitrary position, and it is not limited to linear grooves arranged in parallel, and various shapes can be adopted.

FIG. 12 is a front view of the lock portion 3 in a closed state with the band 2 omitted. FIG.
FIG. 5 is a front view of the lock portion 3 in an opened state with the band 2 omitted. As shown in FIG. 1 and FIG.
An opening / closing unit 7 is provided at the upper part of the device. As shown in FIGS. 1 and 12, in the closed state of the lock unit 3, the opening and closing unit 7
The cross section of which the front and back are opened by the lock body 33 is formed in a rectangular shape.

The opening / closing portion 7 is provided with a rectangular horizontal plate-like member whose right end is continuous with the hinge portion 32, and is provided vertically downward continuously from the left end of the plate-like member. It is composed of a plate-like member extended to the vicinity,
Is formed in an approximately L-shape. And
A concave portion 82 is provided on the front side of the lower end of the left vertical surface of the opening / closing section 7.
Is provided, and a finger hook 72 made of a rectangular plate-like member protruding horizontally in the left direction is provided.

The other part of the lock part 3 except for the opening / closing part 7 is formed as a locking part main body 33. The upper end of the right part made of a vertical plate-like member is connected to the opening / closing part 7 via a hinge 32. It is installed continuously. Further, a bottom surface is continuously provided from a lower end portion of the right portion by a horizontal plate-like member. A vertical plate-shaped member is continuously provided upward from the left end to the center of the lock portion 3. On the front side of the upper end of the left vertical surface of the lock portion main body 33, a convex portion 81 that can be fitted with the concave portion 82 is protruded, and on the back side, a rectangular horizontally protruded leftward. A finger hook 71 (see FIG. 1) made of a plate-like member is provided.

As shown in FIG. 2, when the opening / closing portion 7 of the locking portion 3 is closed, the projection 81 on the locking portion main body 33 side has a cylindrical shape at a position where it comes into contact with the tip of the opening / closing portion 7. The projection is provided in a posture in which the longitudinal direction is the front-back direction. On the other hand, the concave portion 82 on the opening / closing portion 7 side has a substantially columnar shape into which the convex portion 81 can be fitted, and the convex portion 81 can be fitted when the lock portion 3 is closed at the tip of the opening / closing portion 7. Position. Therefore, the opening and closing unit 7 is closed from the state shown in FIG.
1 is elastically deformed, the concave portion 82 is also elastically deformed, the convex portion 81 is fitted into the concave portion 82, and the convexly deformed convex portion 81 and the concave portion 82 return to their original shapes at the fitted position and become the state shown in FIG. Locked. Therefore, once locked, the lock is maintained unless deliberately released again. In addition, if the opening direction and the like are displayed on the finger hook 72 on the side of the opening / closing part 7 by arrows or characters as shown in FIG. 1, even a first-time user can open the opening / closing part 7 at a glance. But understanding,
It is desirable to accompany such display for recognition.

The hinge portion 32 includes a lock portion 3 and an opening / closing portion 7.
The opening and closing unit 7 is configured to be easily opened and closed by increasing flexibility by making the thickness extremely thin. In addition, since a polymer resin such as PP is used, it can withstand repeated opening and closing.

At the time of closing the lock portion 3 thus configured, the lower left end portion of the opening / closing portion 7 contacts the upper left end portion of the lock portion main body 33 as shown in FIG. The convex portion 81 is fitted into the concave portion 82 on the opening / closing portion 7 side, locked and fixed. Then, a tunnel portion 31 is formed inside, and when an arbitrary portion of the band 2 is inserted into the tunnel portion 31, the inserted band 2 is urged by the elasticity of the lock claw 5, and the upper portion of the tunnel portion 31 is urged. It is pressed against the wall. Therefore, the band 2 is engaged with the engagement portion 5 of the lock claw 5.
1 (see FIG. 5) and the engaging groove 22 (see FIG. 5) of the band 2 are fixed at a position where they engage.

When the lock portion 3 is to be opened, the finger hook 71 of the lock portion main body 33 is fixed with one finger from the state shown in FIG. If raised upward, the protrusion 81 on the lock portion 3 side
The engagement between the opening 82 and the recess 82 on the side of the opening / closing section 7 is released, and the opening / closing section 7 is turned around the hinge 32 as shown in FIG. Since the band 2 pressed against the wall surface above the portion 31 is released and the band 2 can be moved in the direction of the arrow, the band 2 can be removed from the lock portion 3 without having to remove the band 2 to the distal end portion 21. The band 2 can be easily removed from the object.

Next, a method of using the band clamp 1 configured as described above will be described with reference to FIGS. First, as shown in FIG. 2, the band 2 is wound around an object to be bound from a state where the band 2 is not locked by the lock portion 3. Here, the first method is as follows. First, as shown in FIG. 2, the opening / closing portion 7 of the lock portion 3 is set to the open state, and the engaging groove 22 of the band 2 is set so as to abut the engagement portion 51 of the lock claw 5, and the opening / closing portion 7 is closed. To Then, the band 2 penetrates the tunnel portion 31 formed in the lock portion 3 as shown in FIG. According to such a method, even when the length of the band 2 is longer than necessary with respect to the object, there is no need to insert the band 2 from the distal end portion 21 into the lock portion 3. Furthermore, even when the tip 21 of the band 2 is cut off, the band 2 can be set on the lock portion 3 irrespective of the shape of the tip 21. However, since an extra opening / closing operation of the opening / closing section 7 is necessary, a method of inserting the band 2 from the tip 21 of the band 2 into the tunnel section 31 of the lock section 3 as usual is usually used as the second method. Hereinafter, a case in which the tip portion 21 of the band 2 is inserted into the tunnel portion 31 of the lock portion 3 will be described in detail.

FIGS. 6 to 11 are sectional views taken along the line BB of FIG. 3 showing the process of inserting the tip 21 of the band 2 into the lock portion 3 of the band clamp 1. As shown in FIGS. The process of inserting the distal end 21 of the band 2 into the lock portion 3 of the band clamp 1 will be described with reference to FIGS. As shown in FIG. 6, the flexible PP band 2 is bent as shown in FIG. 1, and the tip 21 is inserted from the opening on the rear side of the tunnel 31. The tip portion 21 is tapered in the width direction as shown in FIG. 3, and the length of the rear opening portion of the tunnel portion 31 in the vertical direction is the band 2.
Since there is a sufficient margin as compared with the thickness d3 of the tip portion 21 of the band 2, the tip portion 21 of the band 2 can be easily inserted into the opening of the tunnel portion 31. As shown in FIG. 6, the rear surface of the base 53 of the lock claw 5 is formed to be smoothly curved toward the front, so that the tip 21 of the band 2 inserted into the tunnel 31 is Even if it is slightly deviated downward during insertion, it is guided by the base 53 and comes into contact with the upper wall surface of the tunnel portion 31 as shown in FIGS. At this time, the thickness d3 of the distal end portion 21 of the band 2 shown in FIG. 6 is larger than the distance d4 between the upper wall surface of the tunnel portion 31 and the upper end of the lock claw 5. 7 is bent downward as shown in FIG. 7, so that the distal end portion 21 can enter.

As shown in FIG. 8, the distal end portion 21 enters while the lock claw 5 is further bent downward. At this stage, the engagement portion 51 of the lock claw 5 and the hook groove 2 of the band 2 are engaged.
Since the two projections and depressions do not match, they do not mesh with each other, and the band 2 advances further forward with the lock claw 5 elastically deformed downward. Then, as shown in FIG. 9, at a position where the engaging groove 22 of the band 2 and the engaging portion 51 of the lock claw 5 are engaged,
The lock claw 5 that has been elastically deformed is displaced upward by the elastic repulsive force, and the engaging groove 22 of the band 2 and the meshing portion 51 of the lock claw 5 are engaged.

At this time, even if the band 2 is pulled backward, the vertical surface 22b of the engaging groove 22 of the band 2 (see FIG. 6) and the vertical surface 51b of the engaging portion 51 of the lock claw 5 (see FIG. 6) are engaged. Do not move backwards. On the other hand, when the band 2 is pulled further forward, the force for pulling the band 2 forward is applied to the slope 22a of the hanging groove 22 of the band 2 (see FIG. 6).
And the slope 51a of the engagement portion 51 of the lock claw 5 (see FIG. 6), and as shown in FIG.
The sliding surface 22a (see FIG. 6) slides on the slope 51a of the meshing portion 51 of the locking claw 5 while displacing the locking claw 5 downward, and as shown in FIG. (See FIG. 8) and the engagement portion 51 (see FIG. 8) of the lock claw 5 is shifted to a position shifted by one and engaged again. When the band 2 is pulled forward as shown in FIG. 1 and the band 2 is stopped pulling the object to be bound (see FIG. 31) with the band 2 tightened as shown in FIG. 1, the band 2 is locked at that position. The object is fixed to the part 3 and bound by the band clamp 1.

On the other hand, in order to release the object from the restraint, as shown in FIG. 1, while holding the finger hook 71 of the lock section 3 with a finger, another finger is put on the finger hook 72 of the opening / closing section 7 and twisted. 2, the protrusion 81 on the lock portion 3 and the concave portion 82 on the opening / closing portion 7 are disengaged from each other, and the opening / closing portion 7 rotates about the hinge portion 32 as shown in FIG. . When the opening / closing portion 7 is rotated, the band 2 is inserted into the tunnel portion 31 formed and the band 2 pressed against the wall surface above the tunnel portion 31 is released, and the band 2 can move in the direction of the arrow. As shown, the band 2 can be removed from the lock portion 3 without having to pull it out. Therefore, it is possible to easily remove the band 2 from the object without having to remove the band 2 to the distal end portion 21.

Since the band clamp 1 is configured as described above, it has the following effects. That is, when an object is bound, the band clamp 1 can be set by closing the lock portion 3 and inserting the band portion 2 into the lock portion 3 from the distal end portion 21 of the band 2. Furthermore, in addition to this, the tip 21 of the band 2 is
Even if the band 1 is not inserted, the arbitrary position of the band 2 is aligned with the lock unit main body 33 from the state where the open / close unit 7 shown in FIG. 2 is opened, and the open / close unit 7 is closed with respect to the lock unit main body 33. By doing so, there is an effect that the object can be fixed to the lock portion 3 at an arbitrary position of the band 2 and bound. In this case, even when the band 2 is longer than necessary, it is not necessary to pass the band 2 from the distal end portion 21 to the lock portion 3 each time, and the work can be performed quickly. Further, in a case where an unnecessary portion of the band 2 is cut off, it is difficult to insert the band 2 having a tapered end into the closed lock portion 3. The band 2 whose tip is cut off because it is not necessary to insert the
Can be easily bound even if it is not tapered. Further, once the opening / closing portion 7 is closed, the locking portion composed of the convex portion 81 on the locking portion main body 33 side and the concave portion 82 on the opening / closing portion 7 side is engaged, and in normal use, the engaging portion is engaged. The stop will not come off.

Also, when releasing the object from the restraint, the band 2 can be released only by opening the opening / closing section 7 and the band 5 is operated while operating the conventional unlocking claw 552.
The object can be easily released even in a narrow place where it is difficult to work without troublesome work such as pulling out the 02 (see FIG. 28). Further, since the opening operation can be performed only with a fingertip, tools are not required. Further, when opening the opening / closing section 7, the work can be performed while visually checking the opened portion, so that the efficiency is extremely improved as compared with the case where the lock is released by groping. Furthermore, if arrows are displayed on the finger hooks 71 and 72 as shown in FIG. 1, even a person who handles the band clamp 1 for the first time can easily recognize the open portion at a glance and understand the open method. In addition, the opening / closing section 7 can be easily opened. Further, since the lock release claw 552 (see FIG. 28) is unnecessary, unnecessary protrusions can be eliminated.

Next, a modification of the band clamp 1 of the present embodiment will be described. FIG. 14 is a perspective view of the band clamp 101 in a closed state. FIG. 15 is a perspective view of the band clamp 101 in an opened state. The band clamp 101 is entirely made of flexible PP.
