Description

  The present invention relates to a loop-type clamp for fixing a long member such as a pipe to a structure, and more specifically, a loop-type clamp having an engagement portion for maintaining a “closed state” at a tip thereof, The present invention relates to a closing tool, an opening tool, and an opening / closing tool for a loop type clamp with an engaging portion for deforming from "to" a "closed state".

As disclosed in FIG. 1A of Patent Document 1, FIG. 2 of Patent Document 2, and the like, a loop portion that holds a pipe by bending a belt-shaped metal plate into a substantially “P” shape, and the loop portion And a loop type clamp having two fastening pieces having bolt holes for fixing the clamp to a wall surface or the like.
Such a loop-type clamp is in a state in which the space between the pair of fastening pieces is largely opened in a free state (open state) so that the pipes can be easily inserted and removed. For this reason, when the plate thickness of the loop type clamp is thick, the reaction force of the loop portion is strong, and a large force is required to overlap the two fastening pieces against the reaction force (to make the closed state) It is difficult to fix the loop clamp to the wall surface with a bolt or the like.

For this reason, Patent Document 2 proposes a clamp mounting tool that holds two fastening pieces of a loop type clamp in a “closed state” and allows them to be fixed with bolts or the like as they are. .
Alternatively, in Patent Document 3, the loop-type clamp is separated into two members, a lower band and an upper band, and both members are connected by a hinge portion, and a locking tab is formed at the tip of the lower band and the upper band. Has been proposed. The upper band can be opened and closed in the radial direction around the hinge part with respect to the lower band, and the locking tab can be engaged and disengaged by swinging the neck in the thrust direction. As a result, the clamping reaction force can be eliminated to facilitate attachment.

  Furthermore, like the loop type clamp 100 with an engaging part shown to FIG. 1 (A), (B), the loop part 101 holding elongate members like the piping member P, and the end of this loop part 101 are extended. A first fastening piece 102 and a second fastening piece 103 in which the other end of the loop portion 101 is bent at a right angle, and an arch-shaped or folded-back engaging recess 104 (first shape) is formed at the tip of the first fastening piece 102. There is one in which a single engagement portion is provided, and a tongue-like engagement convex portion 105 (second engagement portion) is provided at the tip of the second fastening piece 103. Bolt holes 106 and 107 (holes) are formed in the first fastening piece 102 and the second fastening piece 103, respectively. 1A and 1B, the first fastening piece 102 and the second fastening piece 103 are in an “open state” in which they are separated from each other.

  As shown in FIGS. 2 (A) and 2 (B), when the piping member P is held by the loop clamp 100 with an engaging portion and fixed to the structure S, the first fastening piece 102 and the second fastening piece are used. The pieces 103 are overlapped with each other to form a “closed state” in which the engagement concave portions 104 and the engagement convex portions 105 are engaged. In this “closed state”, the bolts 110 are inserted into the bolt holes 106 and 107. Is fastened to the bolt hole H of the wall surface W.

According to the loop-type clamp 100 with the engaging portion, the engagement concave portion 104 and the engagement convex portion 105 are engaged with each other so that the first fastening piece 102 and the second fastening piece 103 are overlapped with each other. Since the bolt 110 can be attached while maintaining the “state”, the attachment work is easy.
In addition, since the loop portion 101, the first fastening piece 102, and the second fastening piece 103 are integrally formed, as in the case of the loop-type clamp of Patent Document 3, the inconvenience of increasing the number of parts and the weight increase. There is no concern that

However, in the case of the above-described loop clamp 100 with an engaging portion, since it has the engaging concave portion 104 and the engaging convex portion 105, the clamp mounting tool disclosed in Patent Document 2 is used. Cannot be “closed”.
For this reason, a dedicated closing tool 51 as shown in FIG. 15 is prepared. This is an appearance similar to that of a crimping pliers used in electrical work, and is associated with the tip portions (operating points) of a pair of lever bodies 53 and 54 that are combined in a substantially “X” shape with the fulcrum 52 as a rotation center. Engagement projections 55 and 56 that engage with the bolt holes 106 and 107 of the loop clamp 100 with a joint portion are provided, and when the lever bodies 53 and 54 are firmly gripped, one engagement projection 55 is moved to the other. A slide mechanism (not shown) that slides toward the engagement protrusion 56 is incorporated.
By using the closing tool 51, even if the loop clamp 100 with the engaging portion has a strong reaction force, it can be easily deformed from the “open state” to the “closed state” to engage with the engaging recess 104. The mating convex portion 105 can be engaged.

JP 2011-007256 A JP 2012-236274 A Special table 2012-526254 gazette

  However, the above-described closing tool 51 has to be considerably larger than the size of the loop clamp 100 with the engaging portion because of the structure in which the slide mechanism is built in. For example, the closing tool 51 has the engaging portion in a narrow place. When it is desired to attach the loop clamp 100, it is difficult to use, and in some cases, it cannot be used. In that case, the engagement recess 104 and the engagement protrusion 105 of the loop type clamp 100 with the engagement portion are engaged with each other by using a long nose pliers, etc. There is a risk that it takes time to work, and the loop clamp 100 with an engaging portion may be damaged.

  Further, the above-described closing tool 51 can deform the loop clamp 100 with the engaging portion from the “open state” to the “closed state”, but conversely transforms it from the “closed state” to the “open state”. I couldn't. For this reason, when removing the loop type clamp 100 with an engaging part, the engaging recessed part 104 had to be destroyed etc., and the reuse in a healthy state was impossible.

  The present invention has been made in view of the above circumstances, and with a simple configuration, the loop clamp with an engaging portion can be easily deformed from an “open state” to a “closed state” even in a narrow place. An object of the present invention is to provide a closing tool and an opening tool of a loop type clamp with an engaging portion, and an opening / closing tool.

In order to solve the above problems, the present invention employs the following means.
That is, the closing tool for the loop clamp with the engaging portion according to the present invention is formed by bending a belt-shaped metal plate, holding the long member, and first fastening provided at both ends of the loop portion. A piece and a second fastening piece; a first engagement portion provided at a tip of the first fastening piece; and a tip provided at a tip of the second fastening piece to be engaged with the first engagement portion. A loop-type clamp with an engagement portion comprising a second engagement portion, and a hole formed in each of the first fastening piece and the second fastening piece, the first engagement portion and the second engagement portion. A loop type with an engagement portion for deforming from an “open state” in which the engagement with the joint portion is released to a “closed state” in which the second engagement portion is engaged with the first engagement portion. A clamp closing tool, a fulcrum, a first lever body and a second lever body combined with the fulcrum as a rotation center, and a front A hole fitting portion formed at an action point of the first lever body and fitted into the hole of the first fastening piece of the loop clamp with the engagement portion in the “open state”; A slide edge portion formed at an action point of the lever body, extending longer than the hole fitting portion, and abutting against the second fastening piece of the loop clamp with the engagement portion. Features.

  When the loop clamp with an engagement portion configured as described above is used to deform the loop clamp with an engagement portion from the “open state” to the “closed state”, the hole fitting portion of the first lever body Is fitted into the hole of the first fastening piece of the loop clamp with the engaging portion, and the slide edge portion of the second lever body is applied to the second fastening piece, and in this state, the first lever body and the second lever body Hold.

Accordingly, the second fastening piece is brought closer to the first fastening piece side and pushed into the loop portion side. This is because the slide edge portion that abuts obliquely against the second fastening piece has a component force that presses the second fastening piece toward the first fastening piece side and a component force that presses the second fastening piece toward the loop portion side. This is because they are generated.
Then, by further grasping the first lever body and the second lever body, the second fastening piece slides from the distal end side to the proximal end side of the slide edge portion, and the second engaging portion of the second fastening piece Is engaged with the first engaging portion of the first fastening piece, and the loop clamp with the engaging portion is deformed to the “closed state”.

  Since this closing tool has a simple and slim structure that does not have a built-in slide mechanism, the loop clamp with an engaging part can be easily changed from the “opened state” to the “closed state” even in a narrow space where the equipment is set up. Can be deformed.

  In the above configuration, the first engaging portion has a gate shape in which an intermediate portion is spaced in the width direction of the first fastening piece, and the width of the slide edge portion is set smaller than the spacing interval. preferable.

  According to the closing tool for the loop clamp with the engaging portion having the above-described configuration, the second engaging portion of the second fastening piece pressed by the slide edge portion is just before engaging the first engaging portion of the first fastening piece. The slide edge portion does not interfere with the first engaging portion formed in a gate shape. For this reason, the second engaging portion can be pressed to the end by the slide edge portion to be engaged with the first engaging portion, and the loop clamp with the engaging portion can be easily deformed to the “closed state”. it can.

  The said structure WHEREIN: It is preferable that the said slide edge part is curving or inclined so that the front-end | tip part may be located in the said hole fitting part side rather than the line | wire which connects the base and the said fulcrum.

By bending or inclining the slide edge portion as described above, the inclination angle when the slide edge portion abuts on the second fastening piece (second engagement portion) becomes shallow.
For this reason, the ratio of the component force which presses a 2nd fastening piece to the 1st fastening piece side among two component forces which a slide edge part provides to the 2nd engaging part of a 2nd fastening piece is used for a 2nd fastening piece. It can be made larger than the ratio of the component force pressed to the loop part side.
Thereby, even if the reaction force of the loop type clamp is strong, it can be easily “closed”.
And since it becomes easy to slide a 2nd fastening piece (2nd engaging part) along a slide edge part, abrasion of a slide edge part can be prevented.

  In addition, the opening tool for the loop clamp with an engagement portion according to the present invention includes a loop portion in which a band-shaped metal plate is bent and holding a long member, and a first fastening provided at both ends of the loop portion. A piece and a second fastening piece; a first engagement portion provided at a tip of the first fastening piece; and a tip provided at a tip of the second fastening piece to be engaged with the first engagement portion. A loop-type clamp with an engaging portion comprising a second engaging portion, and a hole formed in each of the first fastening piece and the second fastening piece, and the second engaging portion on the first engaging portion. A loop type with an engagement portion for deforming from a “closed state” in which the joint portion is engaged to an “open state” in which the engagement between the first engagement portion and the second engagement portion is released A clamp closing tool, a fulcrum, a first lever body and a second lever body combined with the fulcrum as a rotation center, and a front Formed between the first fastening piece and the second fastening piece of the loop-type clamp with the engaging portion formed at the operating point of the first lever body and the second lever body in the “closed state”. And a wedge portion.

  When the loop type clamp with an engagement portion having the above configuration is used to deform the loop clamp with an engagement portion from the “closed state” to the “open state”, the first lever body and the second lever body The first lever body and the second lever body are gripped in such a manner that the wedge portion provided on the first and second fastening pieces of the loop-type clamp with the engaging portion is bitten.

As a result, the wedge part bites between the first fastening piece and the second fastening piece, and a force is applied in the direction of separating both fastening pieces, so that the first engagement part provided on the first fastening piece The second engagement portion provided on the two fastening pieces is removed, and the loop clamp with the engagement portion is in the “open state”.
Normally, the taper between the first fastening piece and the second fastening piece of the loop clamp with the engagement portion in the “closed state” becomes wider as the distance from the engagement portion at the tip is increased due to the reaction force of the loop portion. Since a gap is formed in the shape, it is easy to insert the wedge part of the opening tool into this gap.

Like the opening tool, this closing tool has a simple and slim structure without a built-in slide mechanism, etc. To "open state".
Moreover, since the engagement can be released without destroying the first engagement portion or the second engagement portion, the loop clamp with the engagement portion can be reused many times in a healthy state.

  Further, the opening / closing tool of the loop type clamp with an engaging portion according to the present invention includes a loop portion in which a strip-shaped metal plate is bent and holding a long member, and a first fastening provided at both ends of the loop portion. A piece and a second fastening piece; a first engagement portion provided at a tip of the first fastening piece; and a tip provided at a tip of the second fastening piece to be engaged with the first engagement portion. A loop-type clamp with an engagement portion comprising a second engagement portion, and a hole formed in each of the first fastening piece and the second fastening piece, the first engagement portion and the second engagement portion. From the “open state” in which the engagement with the joint portion is released, the first engagement portion is transformed into the “closed state” in which the second engagement portion is engaged, or from the “closed state” to the “open state”. Opening / closing tool for loop type clamp with engagement portion for deforming to a state, with a fulcrum and the fulcrum as the center of rotation The first and second lever bodies mated to each other, and the first fastening piece of the loop-type clamp with the engaging portion formed at the operating point of the first lever body and in the “open state”. A hole fitting portion to be fitted into the hole, and formed at an action point of the second lever body, extends longer than the hole fitting portion, and the second fastening piece of the loop clamp with the engagement portion The loop-type clamp with the engaging portion is formed in a slide edge portion abutted on the tip, and a tip portion on the power point side of the first lever body and the second lever body, and is in the “closed state”. And a wedge portion that enters between the first fastening piece and the second fastening piece.

  According to the opening / closing tool having the above-described configuration, the function of the closing tool described above and the function of the opening tool can be provided. For this reason, the loop type clamp with the engaging portion can be deformed from the “open state” to the “closed state” or from the “closed state” to the “open state” with a simpler configuration.

  As described above, according to the closing tool and the opening tool of the loop clamp with an engaging portion and the opening / closing tool according to the present invention, the loop clamp with the engaging portion can be easily opened even in a narrow place by a simple configuration. The state can be changed from “state” to “closed state” or from “closed state” to “open state”.

  Embodiments of the present invention will be described below with reference to the drawings.

[First embodiment of closing tool]
3A, 3B, and 3C are a front view and a side view showing the first embodiment of the closing tool, and FIG. 4 is a plan view of the closing tool.
The closing tool 1 has a basic shape similar to that of a long nose pliers, and a first lever body 2 and a second lever body 3 are combined in an “X” shape with a fulcrum 4 as a rotation center. The force point side of the first lever body 2 and the second lever body 3 is a grip portion 5 covered with a grip rubber.

  A hole fitting portion 7 is formed at the operating point of the first lever body 2. As shown in FIG. 5, the hole fitting portion 7 is to be fitted into the bolt hole 106 of the first fastening piece 102 of the loop clamp 100 with the engaging portion in the “open state”. The hole fitting portion 7 has a hook shape (notch shape) and is formed so as not to be easily detached from the bolt hole 106 when fitted into the bolt hole 106.

  On the other hand, a slide edge portion 9 is provided at the operating point of the second lever body 3. The slide edge portion 9 extends longer than the hole fitting portion 7 and is formed in a plate shape that is significantly thinner than the thickness of the second lever body 3. For example, the long nose pliers are thinned by scraping both sides. And this slide edge part 9 is contact | abutted to the front-end | tip of the engaging convex part 105 of the 2nd fastening piece 103 of the loop type clamp 100 with an engaging part in an "open state" (refer FIG. 5).

  By the way, as shown in FIG. 1, the engagement concave portion 104 that is the first engagement portion of the loop clamp 100 with the engagement portion has a gate shape with an intermediate portion spaced apart in the width direction of the first fastening piece 102. The separation interval is W1. Further, the width of the engaging convex portion 105 which is the second engaging portion is W2, and W1 <W2 so that the engaging convex portion 105 does not come off from the engaging concave portion 104. On the other hand, the width W3 (see FIG. 3C) of the slide edge portion 9 is set smaller than W1.

  In order to deform the loop clamp 100 with an engaging portion from the “open state” to the “closed state” using the closing tool 1 configured as described above, first, as shown in FIG. The hole fitting portion 7 of the lever body 2 is engaged with the bolt hole 106 of the first fastening piece 102 of the loop clamp 100 with an engaging portion, and the slide edge portion 9 of the second lever body 3 is engaged with the second fastening piece 103. Are brought into contact with the tip of the engaging projection 105. In this state, the grip portion 5 of the first lever body 2 and the second lever body 3 is gripped.

  Thereby, as enlarged and shown in FIG. 5, the second fastening piece 103 is brought closer to the first fastening piece 102 side and pushed into the loop portion 101 side. This is because the slide edge portion 9 that obliquely abuts against the distal end portion (engagement convex portion 105) of the second fastening piece 103 presses the second fastening piece 103 toward the first fastening piece 102 and a component force F1. This is because a component force F2 that presses the second fastening piece 103 toward the loop portion 101 is generated.

  Further, by further grasping the first lever body 2 and the second lever body 3, as shown by an arrow a in FIG. Slide from the distal end side toward the proximal end side. At this time, when the closing tool 1 is rotated in the direction indicated by the arrow b in FIG. 6, the component force F1 that the slide edge portion 9 presses the second fastening piece 103 toward the first fastening piece 102 (see FIG. 5). Is increased, and engagement between an engagement convex portion 105 and an engagement concave portion 104 described later can be facilitated.

  Next, as shown in FIG. 7, the first fastening piece 102 and the second fastening piece 103 come into contact with each other, and as shown in FIG. 8, the engaging convex portion 105 engages with the engaging concave portion 104, and the engaging portion The attached loop clamp 100 is deformed to the “closed state”. For this reason, even if the force which grasps the 1st lever body 2 and the 2nd lever body 3 is loosened, the loop type clamp 100 with an engaging part does not return to an "open state". Thereafter, the hole fitting portion 7 of the first lever body 2 is removed from the bolt hole 106, and the loop type clamp 100 with the engaging portion is fixed to the structure through the bolt through the bolt holes 106 and 107 whose positions are aligned.

  Since the closing tool 1 has a simple and slim structure that does not incorporate a slide mechanism or the like, the loop clamp 100 with an engaging portion can be easily moved from the “opened state” to the “open state” even in a narrow place where the equipment is stood. It can be transformed into a “closed state”.

  Further, since the width W3 (see FIG. 3C) of the slide edge portion 9 is set to be smaller than W1 (see FIG. 1B), the gate-shaped separation interval of the engaging recess 104 is set in FIG. As shown in the enlarged view in the figure, when the engaging convex portion 105 is pressed by the sliding edge portion 9 and engages with the engaging concave portion 104, the sliding edge portion 9 is formed in the engaging concave portion 104 formed in a gate shape. Does not interfere. For this reason, the engagement convex portion 105 can be pressed to the end by the slide edge portion 9 to be surely engaged with the engagement concave portion 104, and the loop clamp 100 with the engagement portion is easily deformed to the “closed state”. Can be made.

[Second Embodiment of Closing Tool]
FIG. 9 is a front view showing a second embodiment of the closing tool.
Since the closing tool 11 shown here has the same configuration as the closing tool 1 shown in FIG. 3 except for the shape of the slide edge portion 9, the same reference numerals are given to the respective portions and description thereof will be omitted.

  In this closing tool 11, the slide edge portion 9 is curved so that the tip end portion 9 a is positioned closer to the hole fitting portion 7 than the line L connecting the base portion 9 b and the fulcrum 4. Instead of curving the slide edge portion 9, it may be refracted and inclined at the position of the base portion 9b.

By bending or inclining the slide edge portion 9 in this way, as shown in FIG. 10, the inclination angle θ when the slide edge portion 9 abuts on the tip end portion (engagement convex portion 105) of the second fastening piece 103. Becomes shallower.
For this reason, of the two component forces F1 and F2 (see FIG. 5) that the slide edge portion 9 applies to the engaging convex portion 105, the component force F1 that presses the second fastening piece 103 toward the first fastening piece 102 side. The ratio can be made larger than the ratio of the component force F2 that presses the second fastening piece 103 toward the loop portion 101, so that even if the reaction force of the loop type clamp 100 is strong, it is easily brought into the “closed state”. be able to.
And since the front-end | tip part (engagement convex part 105) of the 2nd fastening piece 103 becomes easy to slide along the slide edge part 9, abrasion of the slide edge part 9 can be prevented.

[Open tool embodiment]
FIG. 11 is a front view showing an embodiment of the opening tool.
The opening tool 21 has a pliers-like basic shape, and a first lever body 22 and a second lever body 23 are combined in an “X” shape with a fulcrum 24 as a rotation center. The force point side of the first lever body 22 and the second lever body 23 is a grip portion 25.

  Wedge portions 27 are formed at the action points of the first lever body 22 and the second lever body 23, respectively. These wedge portions 27 are opposed to each other like a nipper blade, and a predetermined interval is provided therebetween.

  In order to deform the loop clamp 100 with the engaging portion from the “closed state” to the “opened state” using the opening tool 21 configured as described above, as shown in FIG. The wedge portions 27 of the lever body 22 and the second lever body 23 are bitten between the first fastening piece 102 and the second fastening piece 103 of the loop clamp 100 with an engaging portion, respectively. 22 and the second lever body 23 are gripped.

  As a result, the wedge portion 27 bites between the first fastening piece 102 and the second fastening piece 103, and a force is applied in the direction of separating both fastening pieces 102, 103, as shown in FIG. The engaging convex portion 105 provided on the second fastening piece 103 is removed from the engaging concave portion 104 provided on the first fastening piece 102, and the loop clamp 100 with the engaging portion is in an “open state”.

  As shown in FIG. 13, between the first fastening piece 102 and the second fastening piece 103 of the loop clamp 100 with the engaging portion in the “closed state”, the engagement of the tip is caused by the reaction force of the loop portion 101. A tapered gap D is formed which becomes wider as the distance from the joining portions 104 and 105 increases. Therefore, it is easy to insert the wedge portion 27 of the opening tool 21 into the gap D.

Since the closing tool 21 has a simple structure that does not incorporate a slide mechanism or the like, like the opening tool 1, the loop clamp 100 with an engaging portion can be easily “closed” even in a narrow place where the equipment is stood. To "open state".
In addition, since the engagement can be released without destroying the engagement concave portion 104 and the engagement convex portion 105, the loop clamp 100 with the engagement portion can be reused many times in a healthy state.

[Embodiment of open / close tool]
FIG. 14 is a front view showing an embodiment of the open / close tool.
Since this opening / closing tool 31 has the same configuration as the closing tool 1 shown in FIG. 3 except that a wedge portion 32 is formed at the front end portion (rear end portion) of the grip portion 5, the same reference numerals are given to the respective portions. The description is omitted.

  Like the wedge part 27 of the opening tool 21 shown in FIG. 11, the wedge part 32 is opposed like a nipper blade, and a predetermined interval is provided therebetween. By grasping the grip portion 5 so that the wedge portion 32 is bitten between the first fastening piece 102 and the second fastening piece 103 of the loop clamp 100 with the engaging portion in the “closed state”, Similarly to the opening tool 21 shown in FIG. 11, the loop clamp 100 with the engaging portion can be deformed from the “closed state” to the “open state”. On the contrary, the usage in the case of changing from the “open state” to the “closed state” is the same as that of the closing tool 1 shown in FIG.
