DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid supply hose, a dust-proof bellows, a shaft boot and other fixed objects made of an elastic material such as rubber or synthetic resin, and a corresponding joint pipe or opening / closing cock. The present invention relates to an improvement of a draw-drawing-operation-type clamp fitting that is fastened and fixed to a connection circumferential surface of a rotating shaft and other devices.

[0002]

2. Description of the Related Art A clamp band made of stainless steel or other metal band material cut to a certain length is wound into a circular ring shape partially overlapping one end side and the other end side to form a three-dimensional shape. In addition, as a clamp member of a pull-drawing operation type for manually forcibly deforming and contracting the diameter of the clamp band by pulling-down operation such as a pliers or nippers, JP-A-4-210188, JP-B-5-63641, Patent No. 2758968, No. 2
No. 758969 has been proposed, each of which has a form in which there is no overhanging portion which is crushed by a special caulking tool, so that the weight distribution in the circumferential direction is largely non-uniform and does not interfere with surrounding members in use. In all respects, they are all in common.

[0003] Among them, in the case of Japanese Patent Application Laid-Open No. Hei 4-210188, in particular, the vicinity of the first end (13) in the outer overlapping portion (22) of the band body (11) and the intermediate portion (23) of the band body (11). ), The first and second tool hooking portions (40) and (45) are both formed to protrude outward, and furthermore, the temporary fixing projections (55) which protrude outward from the inner overlapping portion (21). ) And a receiving portion (58) of a projection receiving hole (57) that opens to the outer overlapping portion (22). The temporary fixing means (59) is provided on the band body (11). It is considered to be a known invention that most closely resembles the invention.

[0004]

However, according to the structure of the known invention, the provisional fixing projection (55) is also engaged in the provisional engagement with the receiving portion (58) of the projection receiving hole (57). The locking projections (35) and (35) separate from the first and second locking holes (30a) and (30b) enter and lock.

[0005] Therefore, the drawing operation is performed by drawing from the temporary fixing state shown in FIGS. 1 to 3 to a so-called final tightening state shown in FIGS. To the stop hole (30a), the locking projection (35) separate therefrom
In the transition process in which (35) enters the second and third locking holes (30b) (30c), these inner overlapping portions (2
Projection group (35) (35) projecting outward from 1)
(55) is strongly pushed inward by the outer overlapping portion (22), and the temporary fixing projection (5)
5) The back (55b) forms a smooth inclined surface,
The bulging portions (37) (3) of the locking projections (35) (35)
7), the projections (35), (35), and (55) may buckle improperly in combination with the smooth arch shape.

As shown in FIG. 10, the front walls (36) and (36) of the locking projections (35) and (35) have a protruding height greater than the plate thickness of the band body (11) and have an outer overlapping portion. It rises in a substantially vertical direction from the surface of (22), and in the final tightening state, it is overlapped with the front edges (31) and (31) of the second and third locking holes (30b) and (30c). In addition to the terminal overlapping portion (22), the first end (13) of the outer overlapping portion (22) does not rise, so that the terminal holding portion (50) projects outward from the inner overlapping portion (21) in the tunnel. It is also to be inserted into.

For this reason, it is impossible to manually release the final tightened state shown in FIGS. 6 to 10 and to use the clamp again, which limits its use. In other words, in the above-mentioned known invention, in the maintenance / inspection work of the equipment, if the hose or the boot needs to be replaced, the fastening state of the clamp is released and reuse is not considered at all.

[0008]

[0025]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a clamp according to a first embodiment of the present invention; FIG.
4 to 8 respectively show a product which is wound and bent to form a three-dimensional structure and a use state thereof. The material of the clamp is a fixed thickness (T) (for example, about 0.7 to 1.0 mm).
And stainless steel (for example, SUS301 or SUS304) having a constant width (W) (for example, about 7 to 10 mm).
And other metal strips (M) are used, and the length of the object to be fixed (10) such as the fluid feeding hose, dust-proof bellows, and shaft boots from the previously long object The corresponding length (L) is appropriately cut.

(11) is obtained by winding and bending the metal strip material (M) cut into a fixed size into a circular ring shape as viewed from the front and the rear, thereby forming the fixed object (10). It is a clamp band that directly serves as a tightening action, and partially overlaps by a fixed amount (X) so that the other end side is also circumscribed on one end side of the bend. In other words, the clamp band (11) is in an overlapped state in which one end side of the bent portion forms an inner overlapping portion (11a), and the other end portion of the bent portion forms an outer overlapping portion (11b). (11c) shows an intermediate portion of the remaining non-overlapping clamp band (11).

Needless to say, the clamp band (11) has a constant width (W) of the metal band material (M) itself, but only one of the cut ends of the inner superposed portion (11a) is formed of the metal band material (M). The notch (12) having a constant width (W1) (for example, about 2.5 to 3.0 mm) narrower than the constant width (W) of M) is notched and left. (L1) indicates the overhang length of the nose (12) extending on the longitudinal center line of the metal strip material (M), for example, about 7-1.
It is dimensioned to 0 mm.

In this case, the tip of the nose (12) is formed as a convexly curved pilot piece (12a) and is raised outward by at least a dimension substantially equal to the thickness (T) of the metal strip material (M). I have. Therefore, the pilot piece (12a) of the nose (12) is connected to an outer overlap portion (11
By receiving in the nose receiving slot of b), the inner overlapping portion (11a) and the outer overlapping portion (11b) of the clamp band (11) can be accurately aligned with each other without a risk of lateral displacement. Can be overlapped quickly.

(13) (14) (15) (16) (1
7) is an overlapping portion (1) inside the clamp band (11).
1a) and the nose (1
From 2), in the direction in which the intermediate portion (11c) is present, the latching pin receiving holes for winding and bending forming, the first and second receiving holes for fixing claws, and the first tool for fastening the clamp band are sequentially distributed. A receiving hole and a preliminary tool receiving hole for release, each having a fixed opening width (for example, about 3.5)
.About.5.0 mm) and is scattered on the longitudinal center line of the metal strip material (M).

First, the lock pin receiving hole (13) for winding and bending forms receives a locking pin planted from the circumferential surface of a core metal roll for winding and bending (not shown), and engages with the locking pin. The clamp band (11) is used to form a three-dimensional shape by winding the clamp band (11) into a circular ring shape by rotating the cored bar roll in the stopped state, and the protruding base end of the nose (12). The opening is formed in a circular or elliptical shape in plan view while being located near the portion.

Next, a first receiving hole (14) for a fixed claw is provided.
Is open at a position relatively far away from the locking pin receiving hole (13) as an ellipse in plan view, and in particular, the opening edge on the side adjacent to the locking pin receiving hole (13) is partially In addition, the metal strip material (M) is cut and raised so that the metal strip material (M) swells at an angle approximately equal to the thickness (T) of the metal strip material (M) at the most, and obliquely outward at a certain angle (α). It is shaped as a temporary fixing claw (18).

The first receiving hole (14) has a narrow width (W2) (for example, about 1) from the center of the opening edge of the opening.
２2 mm), the temporary fixing claw (18) raised obliquely outwardly engages with a fixed claw (described later) that protrudes inward in the opposite direction from the outer overlapped portion (11b), thereby engaging and locking. The band (11) is temporarily fixed,
The opening degree of the later-described drawing-type operating tool can be kept almost constant at all times.

Also, the second receiving hole (1
5) is also opened as an ellipse in plan view at a position close to the first receiving hole (14).
The opening edge on the side adjacent to the receiving hole (14) is entirely dimensionally equal to at least the thickness (T) of the metal strip material (M) by cutting and raising the metal strip material (M). However, it is shaped as a final tightening claw (19) which swells obliquely outward at a certain angle (β).

From the opening edge of the second receiving hole (15), the final tightening claw (19) protruding as a high-strength transverse convex shape is engaged with a fixed claw (described later) of the outer overlapped portion (11b). By stopping each other, the clamp band (1
1) can be fixedly maintained as a final so-called final fastening state.

Further, the first tool receiving hole (16) for fastening the clamp band is opened as a long hole in a plan view, which is longer than the first and second receiving holes (14) and (15) for the fixing claws. In particular, the opening edge on the side adjacent to the second receiving hole (15) is cut and raised into a high-strength transverse convex shape, so that at least the thickness (T) of the metal strip material (M) is reduced. ), And is formed as a first tool receiving claw (20) which swells obliquely outward at a certain angle (γ) and having a size substantially equal to that of (1).

In this case, the first tool receiving claw (20) and the final tightening claw (19) are difficult to distinguish at a glance, and in order to prevent erroneous recognition, a spare tool in the first tool receiving hole (16) is required. The opening edge on the side adjacent to the receiving hole (17) is cut out in a non-circular shape such as a V-shape or a straight line in plan view. Using the non-circular shape as a mark, an operation tool described later can be inserted into the first tool receiving hole (16) without error.

The spare tool receiving hole (17) for releasing the clamp band is provided in the first tool receiving hole (16) for fastening.
And the opening edge on the side adjacent to the first tool receiving hole (16) is cut and raised into a high-strength, transversely convex shape. Thus, the auxiliary tool receiving claw (21) is formed to have at least a dimension substantially equal to the thickness (T) of the metal strip material (M) and to bulge obliquely outward at a certain angle (δ).

On the other hand, in the outer overlapped portion (11b) of the clamp band (11), the temporary fixing claws (18) and the final tightening claws are sequentially arranged from the other end of the clamp band toward the direction in which the intermediate portion (11c) exists. (19) and selective receiving hole (2
2), a second tool receiving hole (23) for fastening and releasing the clamp band and a receiving elongated hole (24) of the nose (12) are distributed. All of them also have a constant opening width (for example, about 3.5 to 5.0 mm),
It is needless to say that the metal strip material (M) is scattered on the longitudinal center line.

First, the temporary fixing claw (18) and the final fastening claw (1)
9) is open as an ellipse in plan view at a position closest to the other end of the outer overlapped portion (11b), particularly on the side adjacent to the other end of the cut. Is cut and raised into a high-strength, transversely convex shape, so that at least a dimension substantially equal to the thickness (T) of the metal strip material (M) and at a constant angle (ε). It is shaped as a fixed claw (25) that bulges obliquely inward.

That is, the fixed claw (25) faces the temporary fixing claw (18) or the final tightening claw (19) that protrudes obliquely outward from the inner overlapping portion (11a), and has a certain angle (ε) corresponding to the fixed claw (19). Thus, the clamp band (11) is depressed diagonally in the opposite direction (inward) from the outer overlapping portion (11b) of the clamp band (11), so that the fixing claw (25) is engaged with the temporary fixing claw (18). The clamp band (11) is held in a temporarily fixed state, and the fixed claw (25) bites and locks with the final tightening claw (19) so that the clamp band (11) is overlapped with the inner overlapping portion. On the superposed plane of (11a) and the outer superposed portion (11b), it can be locked and fixed in the final flat and flat state.

Next, the second tool receiving hole (23) for fastening and releasing the clamp band is provided in the selective receiving hole (2).
2), the opening is formed as a long hole in plan view, and the opening edge on the side adjacent to the selection receiving hole (22) is also cut and raised into a high-strength transverse convex shape. By processing, at least the metal strip material (M)
The second tool receiving claw (2) that swells obliquely outward by a dimension substantially equal to the thickness (T) of the
6).

The second tool receiving claw (26) faces the first tool receiving claw (20) of the inner overlapping portion (11a) so as to face the first tool receiving claw (20). It is needless to say that the angle (θ) is maintained obliquely outward from the outer overlapping portion (11b) of the clamp band (11) while maintaining the angle (θ).

In this case, the boundary between the second tool receiving hole (23) and the selective receiving hole (22) allows the narrow temporary fixing claw (18) of the inner overlapping portion (11a) to escape and pass therethrough. As a tunnel (27), it protrudes in a transversely convex shape continuous with the second tool receiving claw (26). In the process of shifting from the temporary fixing state to the final tightening state, the temporary fixing claws (18) are
It is pushed down by 1b) so as not to buckle.

Further, the opening edge of the second tool receiving hole (23) on the side adjacent to the nose receiving long hole (24) is cut out in a non-arc shape such as a V-shape or straight line in plan view. It is preferable to correctly recognize that the second tool receiving claw (26) corresponds to the first tool receiving claw (20) of the first tool receiving hole (16). The non-circular shape is also used as a mark so that an operation tool described later can be inserted into the second tool receiving hole (23) without error.

Further, the receiving slot (2) of the nose (12)
4) receives the nose (12) in the process of shifting the clamp band (11) from the temporarily fixed state to the fully tightened state, so that a step does not occur on the tightening operation surface of the clamp band (11). For that purpose, it is largely opened as a considerably elongated elliptical shape in plan view.

At this time, the tip of the nose (12) serves as a pilot piece (12a), which acts as a pilot to enter the nose receiving slot (24) as soon as possible. (11a) and the outer overlapped portion (11b) do not relatively displace in the lateral direction, and as a result, they can be accurately matched to the overlap state.

(28), (29) and (30) are located in the intermediate portion (11c) of the clamp band (11) where the inner overlap portion (11a) and the outer overlap portion (11b) do not overlap with each other, and A plurality of elongated holes, which are distributed along the longitudinal center line of the strip material (M) and are substantially elongated and have a large opening distribution as an ellipse in plan view, serve to reduce the weight of the clamp band (11) itself.

Since the present invention is an open type clamp having the above-described structure, it is used for a fluid supply hose and a dustproof bellows made of an elastic material such as rubber or synthetic resin.
When fastening the shaft boots and other objects to be fixed (10) to the corresponding connection pipes of the joint pipes, opening and closing cocks, rotating shafts and other various devices (31), the clamps described above are used. The band (11) is wound diametrically around the connection circumferential surface of the fixed object (10), and the temporary fixing claws (18) of the inner overlapped portion (11a) are set to the outer overlapped portion (18) as shown in FIGS. By temporarily engaging the fixed claw (25) of FIG.

In the temporarily fixed state of the clamp band (11), as apparent from FIGS.
The pilot piece (12) of the nose (12) in 1a)
a) enters the nose-receiving slot (24) of the outer superposed portion (11b), and the inner superposed portion (11a) and the outer superposed portion (11b) overlap with each other accurately, and In addition, the first of the inner polymerized portion (11a)
The tool receiving claw (20) and the second tool receiving claw (26) of the outer overlapping portion (11b) are arranged side by side in an inclined posture opposite to each other and at a constant interval (D1).

Then, a pair of left and right working claws (3) provided at the distal end of a drawing-type operating tool (P) as shown in FIG.
2) is inserted into the first and second tool receiving holes (16) and (23) of the clamp band (11) and the first and second tool receiving holes (16) and (23) are inserted.
The tool receiving claws (20) and (26) are engaged. The first and second tool receiving claws (20) (2)
The constant interval distance (D1) of (6) is useful for always keeping the two operating claws (32) of the operating tool (P) at a constant opening degree, and it is not necessary to widen the large distance.

Then, the pair of right and left handles (33) of the operating tool (P) is strongly squeezed and tightened, and the two operating claws (32) are turned around the assembly fulcrum shaft (34) as shown in FIGS. In this process, the diameter of the clamp band (11) is forcibly contracted and deformed, and in the process, the pilot piece (12a) of the nose (12), which forms one end of the cut-off portion of the inner overlap portion (11a), is connected to the outer overlap portion. It advances along the nose receiving slot (24) of (11b).

On the other hand, as the drawing operation is continued,
A fixed claw (25) located at the other end of the cut off of the outer overlapped portion (11b), and a final fastening claw (1) of the inner overlapped portion (11a).
9) move over each other so that the two overlapping portions (11a) and (11b) eventually bite and lock on the overlapping plane, and the clamp band (11) is moved to the position shown in FIG. As a result, the object to be fixed (10) is fixed to the connection circumferential surface of the various devices (31) in a tightened state as a result of being locked in a flat and fully tightened state as shown in FIG.

In this case, the distance (D2) between the preliminary tool receiving pawl (21) and the second tool receiving pawl (26) in the final tightening state is equal to the first and second tool receiving pawls (20) in the temporary fixing state. (26) mutual spacing distance (D1)
Approximately equal dimensions.

In order to maintain such a relation, the first and second tool receiving claws (20) (26) and the first and second tool receiving claws (20) and (26) are provided on the inner overlapping portion (11a) and the outer overlapping portion (11b) of the clamp band (11). Spare tool receiving claws (21), temporary fixing claws (18), final tightening claws (19) and the like are arranged and arranged.

Further, during the drawing operation of the clamp band (11) from the temporarily fixed state to the fully tightened state, the temporarily fixed claw (18) which protrudes outward from the inner overlapped portion (11a) of the clamp band (11) is moved outwardly. Part (11b) of tunnel (2
7) Relatively pass through the inside, and its outer polymerization portion (11b)
Is strongly pressed down and there is no danger of buckling. Therefore, even if the final fastening state is released by natural external force such as violent vibration or impact during use of the clamp, even if the final overlap state is canceled, 11b) fixed claw (2
5) is received by the temporary fixing claws (18) of the inner superposed portion (11a), and there is no risk of falling off from the fixed object (10).

After the fixed state is maintained, the two operating claws (32) of the operating tool (P) are removed from the first and second tool receiving holes (16) and (23) of the clamp band (11). Needless to say, pulling it out.

Further, in the clamp according to the present invention, a spare tool receiving hole (17) for release is also formed in the overlapping portion (11a) inside the clamp band (11).
The opening edge serves as a spare tool receiving claw (21).
Since the second tool receiving claw (26) of the second tool receiving / closing hole (23) for fastening and releasing in the outer overlapped portion (11b) is installed in parallel with the second tool receiving claw (26) in an inclined posture state opposite to the above, the above-mentioned final tightening state is intended. It can also be canceled manually.

In other words, as shown in FIG. 16, in releasing the work, the spare tool receiving hole (17) of the inner overlapping portion (11a) and the second tool hole of the outer overlapping portion (11b) are used.
The double action claw (32) of the drawing-type operating tool (P) is also inserted into the tool receiving hole (23), and this is engaged with the spare tool receiving claw (21) and the second tool receiving claw (26). It is.

At this time, the distance (D2) between the preliminary tool receiving claw (21) and the second tool receiving claw (26) in the final tightening state is equal to the first and second tool receiving claws (20) in the temporarily fixed state. Since the dimensions are almost equal to the mutual distance (D1) of (26), it is not necessary to expand both action claws (32) of the operating tool (P) so much that the opening degree is always constant. As a constant, it can be easily and quickly engaged, and the drawing operation can be performed reliably and conveniently.

When the drawing operation is performed, the locking state of the fixed nail (25) of the outer overlapped portion (11b) and the final tightening claw (19) of the inner overlapped portion (11a) is locked. As shown in FIG. 17, the forcible object (1) is forcibly released from the connection circumferential surface of the various devices (31).
0) can be removed and replaced, and the necessity of maintenance and inspection can be dealt with, and the use of the clamp fitting is expanded. It is needless to say that the temporary fixing claws (18) of the clamp band (11) do not buckle, so that the clamp of the present invention can be used repeatedly.

FIGS. 18 to 26 show, as a second embodiment of the present invention, a clamp having a relatively small diameter of the clamp band (11). The formation of the opening of the first receiving hole (14) for the fixed claw with respect to 11a) and the installation of the temporary fixing claw (18) bulging from the opening edge are omitted.

That is, in the case of the second embodiment, the inner overlapping portion (11a) of the clamp band (11) is sequentially moved from the nose (12) on one end side of the clamp band toward the direction in which the intermediate portion (11c) exists. A lock pin receiving hole (13) for winding and bending, a fixed claw receiving hole (15), a first tool receiving hole (16) for fastening a clamp band, and a spare tool receiving hole (17) for releasing are respectively distributed. On the other hand, similarly, the outer overlapping portion (11b) of the clamp band (11) is connected to the intermediate portion (11
The receiving hole (22) of the final tightening claw (19), the second tool receiving hole (23) for fastening and releasing the clamp band, and the long receiving hole (23) of the nose (12) are sequentially arranged in the direction of presence of c). 24) are each aperture-distributed.

In the clamp fitting in which the clamp band (11) is wound and formed into a three-dimensional circular ring having a relatively small diameter as in the second embodiment, the double-acting claw (32) of the drawing-type operating tool (P) is used. ) Is not required to be greatly expanded, and the opening degree is easily maintained constant, so that the provision of the temporary fixing claws (18) is not necessarily required.
On the other hand, since the radius of curvature is small, it is difficult to artificially forcibly release the final tightened state where the final tightening claws (19) and the fixing claws (25) are engaged and engaged with each other. , The inner overlapping portion (11) of the clamp band (11).
The necessity of installing a release preliminary tool receiving hole (17) and a preliminary tool receiving claw (21) that protrudes from an opening edge thereof increases in a).

In the case of a clamp having a relatively small diameter of the clamp band (11), as shown in FIGS.
The nose receiving slot (24) opening into the b) is formed to be much thinner than that of the first embodiment, so that the intermediate portion (11) of the clamp band (11) is formed.
c) separate punched slots (28) (29) (30)
Can be omitted.

Since the other configuration in the second embodiment is substantially the same as that in the first embodiment, FIG.
Only the reference numerals corresponding to those in FIGS. 1 to 17 are written in 8 to 26, and the detailed description thereof is omitted.

In any case, according to the present invention, the fixing claw (25) which is depressed obliquely inward from the position of the other end where the outer overlap portion (11b) of the clamp band (11) is separated from the other end position is also separated from the inner overlap portion (11a). The final tightening claws (19) protruding in the opposite diagonally outward direction are engaged with each other by biting, and the final tightening state of the clamp band (11) is changed to the overlapping portion (11).
a) Since it is designed to be locked and locked on the overlapping plane of (11b), there is no danger that the fixing claw (25) of the outer overlapping portion (11b) warps and floats,
As a result, as in the invention of JP-A-4-210188 described at the beginning, the terminal holding portion (5) is moved from the inner overlapping portion (21).
No. 0) is formed in a special tunnel form, and the first end (13) of the outer overlapping portion (22) does not need to be inserted into the inside of the special tunnel. The premise that becomes possible is completed.

Further, in the present invention, the above-mentioned final tightening claw (1) is used.
The part where the 9) and the fixed claw (25) are engaged with each other by biting
The first tool receiving claw (20) of the inner overlap portion (11a)
And the second tool receiving claw (2) of the outer overlapping portion (11b)
6), and is located on the inner side of the fixed distance (D2), so to speak, between the first tool receiving claw (20) of the inner overlapped portion (11a) and the final tightening claw (19). By providing a spare tool receiving claw (21) for releasing the clamp band on the opposite adjacent side,
A drawing-type operating tool for fastening the clamp band (P)
, The final tightening state of the clamp band (11) can be intentionally released.

In this regard, in the configuration of the above-mentioned Japanese Patent Application Laid-Open No. Hei 4-210188, the first and second tool hooks (40) and (45) are used.
At a position far away outward from the mutual spacing distance (w) of the band body (11), the inner overlapping portion (2) of the band body (11).
Projection group (35) (35) projecting outward from 1)
(55) are the first to third locking holes (30a), (30b), and (30c) also distributed in the outer overlapping portion (22).
And the first end (13) of the outer overlapping portion (22) is overlapped with the inner overlapping portion (2).
Since the terminal holding portion (50) raised from 1) is inserted into the tunnel, the arm tip portion (6) of the tool (60) is manually forcibly released from its fully tightened state shown in FIGS.
2a) and (63a) by the first and second tool hooks (40) (4)
In the case where the first end (13) is engaged with 5) and the drawing operation is performed, the first end (13) enters the tunnel of the terminal holding portion (50) further deeply, and the final tightening state is intentionally released. It is impossible.

Furthermore, by arranging the first tool receiving claw (20) of the inner overlapping portion (11a) in the present invention at the position of the preliminary tool receiving claw (21) for releasing the clamp band, the separate tool receiving claw (21) is provided. Spare tool receiving claw (2
The installation of 1) is omitted, and the first and second tool receiving claws (20)
(26) Double acting claw (3
2) may be engaged to intentionally release the fully tightened state of the clamp band (11). However, when the clamp band (11) is locked in the fully tightened state, the operation tool (P) may be used. The two action claws (32) must be greatly expanded, and a large amount of force is required for the drawing operation. As a result, a large amount of clamps cannot be quickly fastened by light labor.

In the configuration of the present invention, the clamp band (1
The first overlapped tool receiving claw (20) and the separate preliminary tool catch claw (2) for release are provided on the inner overlapping portion (11a) of (1).
The provision of 1) has a special technical meaning in that such a problem can be improved.

In particular, according to the configuration of the first embodiment,
The temporary fixing claws (18) of the clamp band (11) are also the first and second claws.
The interspace distance (D1) between the first and second tool receiving claws (20) and (26) in the temporarily fixed state is interposed between the opposed tool receiving claws (20) and (26).
Spare tool receiving claw (21) in final tightening state and second
Since the distance (D2) from the tool receiving claw (26) is set to be approximately equal, the pulling and drawing is always performed when the clamp band (11) is fully tightened and intentionally released. There is also an advantage that the drawing operation can be quickly and conveniently performed with the opening degree of the operation tool (P) being fixed.

[0072]

As described above, according to the structure of the present invention, the clamp band (11) made of the metal strip material (M) cut to a predetermined length (L) is turned into one side by bending and bending one side. The part (11a) and the outer overlapping part (11b) which is the same as the other end side of the bending part are rolled and bent into a circular ring shape partially overlapping by a certain amount (X), and the diameter of the clamp band (11) is obtained.

In the clamp fitting fastened and fixed to the connection circumferential surface of the device (31),

The cut end of the inner superposed portion (11a) is cut out as a nose (12) having a fixed width (W1) smaller than a fixed width (W) of the metal strip material (M).

The first and second receiving holes for the fixed claw are sequentially formed in the inner overlapping portion (11a) from the nose (12) toward the direction in which the intermediate portion (11c) of the clamp band (11) does not overlap. (14) (15), the first tool receiving hole (16) for clamping the clamp band and the spare tool receiving hole (17) for releasing are respectively distributed in the opening,

The opening edge on the side adjacent to the nose (12) in the first receiving hole (14) for the fixed claw is used as a temporary fixing claw (18) of the clamp band (11), and the second receiving hole (18) for the fixed claw. The opening edge on the side adjacent to the first receiving hole (14) in (15) is also used as the final tightening claw (19) of the clamp band (11), and is cut and raised obliquely outward at a certain angle (α) (β). Along with

The opening edge of the first tool receiving hole (16) on the side adjacent to the second receiving hole (15) for the fixed claw is used as a first tool receiving claw (20), and the spare tool receiving hole (17) is used. The opening edge on the side adjacent to the first tool receiving hole (16) is used as a spare tool receiving claw (21) and cut and raised obliquely outward at a constant angle (γ) (δ), respectively.

The outer overlapped portion (11b) receives the temporary fixing claws (18) and the final tightening claws (19) sequentially from the other end of the outer overlapped portion (11b) toward the direction in which the intermediate portion (11c) exists. The holes (22), the second tool receiving holes (23) for fastening and releasing the clamp band and the receiving elongated holes (24) of the nose (12) are respectively distributed in the openings,

The temporary fixing claw (18) is formed by using the opening edge on the side adjacent to the other end of the clamp band (11) in the selective receiving hole (22) adjacent to the other end as the fixing claw (25).
And an opening edge on the side adjacent to the selection receiving hole (22) in the second tool receiving hole (23), which is cut and raised obliquely inward at a predetermined angle (ε) corresponding to the final tightening claw (19). As a second tool receiving claw (26), cut and raised obliquely outward at a certain angle (θ) facing the first tool receiving claw (20),

From the temporarily fixed state of the clamp band (11) in which the temporary fixing claws (18) of the inner overlapped portion (11a) and the fixed claws (25) of the outer overlapped portion (11b) are bitten and locked. The operating claw (A) of the drawing and drawing operation tool (P) engaged with both the first tool receiving claw (20) of the inner overlapping portion (11a) and the second tool receiving claw (26) of the outer overlapping portion (11b). 32), the fixed claw (25) of the outer overlapped portion (11b) is engaged with the final tightening claw (19) of the inner overlapped portion (11a) by the drawing operation, and the clamp band (11) is engaged.

The second tool receiving claw (26) of the outer overlapped portion (11b) and the spare tool receiving claw (21) of the inner overlapped portion (11a) which are in the fully tightened state are engaged with each other. Since the final tightening state is intentionally released by pulling and squeezing the action claw (32) of the operating tool (P), the problem of the prior art described at the beginning can be completely improved. The effect is also achieved by the configuration according to the third aspect.

In particular, if the structure according to claim 2 is employed as the pulling operation type clamp, the final tightening of the clamp band (11) and the intentional release thereof are performed by the operating tool (P) having a constant opening. By doing so, the operation can be carried out conveniently with a small amount of labor, and there is no need to open the both action claws (32) of the operating tool (P) too much.

2. Description of the Related Art A clamp band made of stainless steel or other metal band material cut to a certain length is wound into a circular ring shape partially overlapping one end side and the other end side to form a three-dimensional shape. In addition, as a clamp member of a pull-drawing operation type for manually forcibly deforming and contracting the diameter of the clamp band by pulling-down operation such as a pliers or nippers, JP-A-4-210188, JP-B-5-63641, Patent No. 2758968, No. 2
No. 758969 has been proposed, each of which has a form in which there is no overhanging portion which is crushed by a special caulking tool, so that the weight distribution in the circumferential direction is largely non-uniform and does not interfere with surrounding members in use. In all respects, they are all in common.

[0003] Among them, in the case of Japanese Patent Application Laid-Open No. Hei 4-210188, in particular, the vicinity of the first end (13) in the outer overlapping portion (22) of the band body (11) and the intermediate portion (23) of the band body (11). ), The first and second tool hooking portions (40) and (45) are both formed to protrude outward, and furthermore, the temporary fixing projections (55) which protrude outward from the inner overlapping portion (21). ) And a receiving portion (58) of a projection receiving hole (57) that opens to the outer overlapping portion (22). The temporary fixing means (59) is provided on the band body (11). It is considered to be a known invention that most closely resembles the invention.

[0004]

However, according to the structure of the known invention, the provisional fixing projection (55) is also engaged in the provisional engagement with the receiving portion (58) of the projection receiving hole (57). The locking projections (35) and (35) separate from the first and second locking holes (30a) and (30b) enter and lock.

[0005] Therefore, the drawing operation is performed by drawing from the temporary fixing state shown in FIGS. 1 to 3 to a so-called final tightening state shown in FIGS. To the stop hole (30a), the locking projection (35) separate therefrom
In the transition process in which (35) enters the second and third locking holes (30b) (30c), these inner overlapping portions (2
Projection group (35) (35) projecting outward from 1)
(55) is strongly pushed inward by the outer overlapping portion (22), and the temporary fixing projection (5)
5) The back (55b) forms a smooth inclined surface,
The bulging portions (37) (3) of the locking projections (35) (35)
7), the projections (35), (35), and (55) may buckle improperly in combination with the smooth arch shape.

As shown in FIG. 10, the front walls (36) and (36) of the locking projections (35) and (35) have a protruding height greater than the plate thickness of the band body (11) and have an outer overlapping portion. It rises in a substantially vertical direction from the surface of (22), and in the final tightening state, it is overlapped with the front edges (31) and (31) of the second and third locking holes (30b) and (30c). In addition to the terminal overlapping portion (22), the first end (13) of the outer overlapping portion (22) does not rise, so that the terminal holding portion (50) projects outward from the inner overlapping portion (21) in the tunnel. It is also to be inserted into.

For this reason, it is impossible to manually release the final tightened state shown in FIGS. 6 to 10 and to use the clamp again, which limits its use. In other words, in the above-mentioned known invention, in the maintenance / inspection work of the equipment, if the hose or the boot needs to be replaced, the fastening state of the clamp is released and reuse is not considered at all.

The drawing-operated clamp according to claim 1, wherein the distance between the second tool and the auxiliary tool receiving claw is substantially equal. 3. A clamp band (11) made of a metal strip material (M) cut to a predetermined length (L) is wound and bent at the other end similarly to an inner overlapped portion (11a) at one end of the bend. By winding and bending into a circular ring shape in which the outer superposed portion (11b) on the side partially overlaps by a fixed amount (X), the diameter of the clamp band (11) is artificially forcibly contracted and deformed. , A fluid supply hose made of an elastic material such as rubber or synthetic resin, a dust-proof bellows, a boot for a shaft, and other fixed objects (10) to connection peripheral surfaces of various corresponding devices (31). In the clamp for fastening and fixing, a cut-off end of the inner overlapped portion (11a) is cut out as a nose (12) having a fixed width (W1) smaller than a fixed width (W) of the metal strip material (M). In the mating portion (11a), from the nose (12) to the direction in which the non-overlapping intermediate portion (11c) of the clamp band (11) is present, the fixing claw receiving hole (15) and the first clamp band fastening first are formed. Tool receiving hole (16) and release spare tool receiving hole (1
