Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in fixtures for pipes.

[0002]

[Prior art and its technical problems] Various structures such as factories, sales offices, shops, apartments, warehouses, stations, gymnasiums, theaters, and various structures such as tunnels, underpasses, elevated railways, elevated roads, bridges, etc. In this case, work is performed to lay cables and lines for power supply and communication, or pipes through them or pipes for sending fluid such as gas on the ceiling, side walls and floors. When laying such pipes, generally, a method of arranging grooved rails in parallel at regular intervals, crossing the pipes on these grooved rails in a cross shape, and tightening and fixing with a fixture is a method. Be taken. In the normal case, it is required that a plurality of pipes be fixed in parallel to the grooved rail. Therefore, the pipe fixing work at each point is a process of temporarily fixing the pipe so that it can be moved only in the longitudinal direction of the rail without separating it from the grooved rail, and adjusting the position of the pipe in this state. In general, two steps of the main fixing step for firmly fixing the pipe are adopted. Since the fixing work of such a process has to be repeated at each intersection with each groove-shaped rail, the number of man-hours is extremely large per construction. In addition, for example, as a mode of fixing the pipe on the ceiling, when the pipe is placed on a grooved rail whose groove entrance faces upward and fixed, and when the pipe is applied from below to the grooved rail whose groove entrance faces downward. Sometimes fixed. In the former case, there is often only a narrow working space between the ceiling and the grooved rails, while in the latter there is a large free space, but work in an uncomfortable position with the neck bent backward by nearly 90 degrees Become.

Conventionally, as a fixing device of this kind, the actual open sho 63
-48085. In this prior art, the fixture includes a metal fitting body having a holding portion that surrounds a half circumference of the pipe, following a leg portion having a T-shaped front surface,
It consists of a screw inserted into a seat provided on the side opposite to the leg of the metal fitting body, and a flat blade plate screwed into the screw. Then, the rotation is stopped by abutting the longitudinal end face of the vane against the inner wall of the flange of the rail member, and the vane is raised along the inner wall of the flange by the subsequent rotation of the screw, and the upper surface of the vane is attached to the wall of the rail member. It is designed to be tightened by touching the lower surface. However, in this prior art, the blade plate is inserted into the groove-shaped rail by adjusting the posture so that its longitudinal direction is parallel to the groove direction of the groove-shaped rail, and the screw is rotated many times in that state. You have to raise the blade. For this reason, it is necessary for one person to apply the pipe to the grooved rail and another person to operate the fixing tool, which causes a problem that the temporary fixing work is extremely time-consuming and troublesome. Further, it is necessary to rotate the screw to perform the temporary fixing. If the screw is mistakenly turned counterclockwise at that time, the blade plate will come off the screw and fall into the grooved rail, and it will take time and time to take it out, thus lowering the efficiency. In addition, if the groove of the grooved rail is facing downward, there is a risk that the blade plate removed from the screw and the pipe removed from the metal fitting body may fall and hit the head or face of the worker, resulting in personal injury. there were.

US Pat. No. 4,770,378 proposes that a vane be suspended by a spring interposed between a seat portion and a screw head portion. However, also in this prior art, in order to perform temporary fixing, the screw is pushed in the axial direction against the spring force of the spring to lower the vane to the bottom of the hanging wall of the grooved rail, and the screw is rotated in that state. It is necessary to perform a two-step operation in which the blade plate is swung orthogonally to the grooved rail. For this reason, also in this prior art, it takes time and labor, and the twist of the wrist is repeated, so that the fatigue of the worker is increased. Further, since the screw must be rotated for temporary fixing, it is unavoidable that the screw is accidentally rotated in the counterclockwise direction and the blade plate comes off to cause the above-mentioned trouble.

Further, in any of the prior arts, the holding portion of the main body has a leg portion extending downward on the side opposite to the seat portion, and a locking portion protruding in the width direction at the lower end of the leg portion. Was provided. For this reason, it is indispensable to insert the legs into the groove-shaped rails and hook the locking portions to the lower end of the wall forming the inlet groove prior to fixing the pipe. therefore,
It was unavoidable that the work was troublesome and the efficiency decreased at this stage. Further, in any of the prior arts, as the next step, it is necessary to tilt the main body with the leg portions locked to the grooved rails to the open side as described above and cover the pipe with the holding portion. However, since the rotation of the blade plate is restricted by abutting the longitudinal ends of the blade plate on the inner walls of the left and right flanges of the grooved rail as described above, the dimension of the blade plate becomes very long. . Therefore, when the pipe is held by the holding portion, the vane plate becomes an obstacle, and the direction of the vane plate must be rotated and adjusted by 90 degrees so as to be orthogonal to the groove direction of the grooved rail. Then, at the stage of starting the temporary fixing, the screw member must be operated again to adjust the direction of the blade plate by 90 degrees so as to be parallel to the groove direction of the rail.
For this reason, workability is also poor in this respect and work efficiency is reduced. In addition, since the rotation of the blade plate is stopped by the longitudinal end surface of the blade plate contacting the inner wall of the flange of the grooved rail, depending on the surface texture of the inner wall of the flange, the blade is caught at an angle instead of orthogonal to the rail groove direction. Due to this, the screw cannot be rotated, or the blade plate rises at an angle. For this reason, the end surface of the groove-shaped rail member is not tightened sufficiently with the end surface of the hanging wall, and it is tightened, which tends to result in an unstable and uncertain tightening state, and there is concern about the fixing performance.

The present invention was devised in order to solve the above-mentioned problems, and an object of the present invention is to perform temporary fixing work of pipes by one-touch operation without screw operation. Another object of the present invention is to provide a fixture for pipes that can reliably and efficiently perform pipe fixing work.
Further, in addition to the above, another object of the present invention is that even if the operation of locking the main body to the grooved rail is not required, no skill is required for a complete one-touch operation, and piping is extremely simple, reliable and efficient. An object of the present invention is to provide a fixture for pipes that can perform fixing work. Still another object of the present invention is, in addition to the above object, that the tightening tool is small, and the direction of the tightening tool does not need to be changed at the time of a covering operation for holding the pipe, and loosening does not occur after fixing the pipe. It is to provide a fixture for pipes. In the present invention, "pipes" is a concept including a power supply line, a communication line, a conduit for protecting them through a strip such as a cable, a pipe for sending a fluid such as gas, and a cable or a bundle thereof. is there. The material of the pipes is not limited, and includes both soft (or flexible) materials such as plastic and rigid materials such as iron-based, stainless-based, copper-based, aluminum-based, and ceramic-based materials.

[0007]

To achieve the above object, the present invention provides a main body having a holding portion having a shape corresponding to the sectional shape of piping, a screw member inserted into the seat portion, and a screw member. The structure is such that it is tightened by screwing. Further, the tightening tool has a central nut member and a pair of left and right tightening pieces supported by the nut member so as to be swingable about a horizontal axis, and each tightening piece includes a tightening portion and the tightening portion. An elastic member that has a stopper surface that rises from the base end and is capable of contacting the wall that forms the grooved rail entrance groove, and that the fastener is normally suspended by a screw member and interposed between the nut member and the seat portion. Are pulled toward the opposite seat by the main body, and when the main body is attached to the pipes, the tightening piece once narrows due to contact with the wall forming the grooved rail inlet groove, then expands and tightens each. The part is configured to be located on the lower surface of the wall.

The tightening tool has a width dimension smaller than the inner groove width of the groove-shaped rail even when the left and right tightening pieces are fully opened. Then, the fastening tool has a restoring element for re-opening the fastening piece after it has collapsed.
The holding portion does not have a T-shaped locking portion which is hooked in the groove-shaped rail on the side opposite to the seat portion, and the tip end preferably ends at a higher level than the seat portion. The holding portion is provided with an adhesive surface for the pipes if necessary. Further, the seat portion of the main body preferably has a guide portion extending to a level below the upper end of the fastening piece. This guide portion maintains the posture of the fastener in a relationship orthogonal to the entrance groove of the grooved rail, and also functions to guide the fastener to rise vertically when the screw member is rotated for final fixing. Fulfill. At the same time, it also has a function of preventing the main body from coming off the inlet groove of the grooved rail when the pipes are moved along the grooved rail in the temporarily fixed state. Preferably, the screw member is restricted from projecting upward from the seat portion by the floating prevention element. This is simply arranged in a part of the screw member, but more effectively, an elastic member is used, and the elastic member is interposed between the nut member and the seat portion to move the nut member in the direction opposite to the seat portion. Press.

[0009]

[Function] When temporarily fixing the pipes, the holding portion of the main body is positioned directly above the pipes which are orthogonally crossed on the grooved rail, and in this state, the main body is pressed toward the grooved rail. To do. That is, by the above operation, the holding portion approaches the outer surface of the pipes, and at the same time, the pair of fastening pieces come into contact with the pair of walls forming the inlet groove of the grooved rail, and the fastening pieces are pressed by the pressing force applied to the main body. Is forced to be swung symmetrically about a horizontal axis. Then, the fastening piece returns to the expanded state at the moment when the outer ends pass through the lower ends of the pair of walls, the stopper surface contacts the pair of walls, and the fastening portion contacts the lower surfaces of the pair of walls, or approach. If the position of the pipes is adjusted on the grooved rail in this state and the screw member is rotated when the position is determined, the nut member and the tightening piece rise as the screw member enters the nut member. At this time, since each stopper portion of the fastening piece faces the pair of walls, rotation of the fastening piece around the vertical axis is restricted, and the fastening tool rises in a state of being orthogonal to the inlet groove of the grooved rail, Since the tightening portion is in strong contact with the lower surfaces of the pair of walls, the pipes are firmly clamped and fixed on the grooved rail by the holding portion. In this state, the elastic member is forcibly compressed, so that the tightened state does not loosen. If a guide portion that extends downward is provided at the tip of the seat,
Before and after the temporary fixing work, the fastening piece is always kept accurately in the predetermined direction, that is, the posture orthogonal to the groove-shaped rail, and is smoothly guided even when the fastening tool is raised. The fastener according to the present invention is designed to be clamped by utilizing the wall forming the entrance groove of the grooved rail, and the fastener rotates about the horizontal axis.
Therefore, since the fastening tool can be made compact with a short width and depth, the fastening tool does not occupy the area of the holding portion and does not hinder the holding of the pipes by the holding portion. When an elastic member is used as the floating prevention element and is interposed between the nut member and the seat portion and the nut member is normally pressed in the direction opposite to the seat portion, the screw member and the tightening tool are The distance from the seat is regulated to a constant value, and the screw member does not project upward from the seat when the main body is pushed down and the tightening tool is recessed. Moreover, since the elastic member is forcibly compressed when the screw member is rotated for the main fixing, the tightened state does not loosen after the main fixing.

FIG. 6 None FIG. 8 shows an embodiment of the fastener 3 in detail. A pair of protrusions 3 of the fastening pieces 3A, 3A
Nos. 0 and 30 are slopes 305 and 305 descending from the apexes of the stopper surfaces 300 and 300, so that the protrusion 30 has a front claw shape or a triangular shape as a whole. The descending slopes 305, 305 are formed in the inlet groove 4 as described later.
This is because when the fastening pieces 3A, 3A are pushed into the 2, the fastening pieces can be recessed without colliding with each other. The downward slope may be a curved surface as well as a straight surface. Web 3a, 3 of each tightening piece 3A, 3A
a is the protrusion 30 at a level lower than the tightening portion 31.
It has an inclined surface 304 parallel to or close to the downward slope 305. This is so that the smooth constriction of the fastening pieces 3A, 3A can be obtained from the state of contacting the top wall 4c of the groove-shaped rail 4. And the web 3
The a and 3a are connected from the upper end of the inclined surface 304 to the tightening portion 31 as an upright surface 303 parallel to the stopper surface 300. The inclined surface 304 and the upright surface 303 may have a gentle curvature surface instead of a straight surface. And the web 3
The lower end 306 of the inclined surface 304 of “a” cooperates with the nut member 3B to regulate the spread angle of the tightening piece, and thus ends before reaching the rear end surfaces 307 and 307 of the flanges 3b and 3b as illustrated in FIG. There is.

The nut member 3B has a flat rectangular head portion 37.
0, and a leg portion 371 which is continuous with the head portion 370 and has a reduced width in the left-right direction, and has a T-shape or a similar shape when viewed from the front. The lower surface of the head portion 370 is provided with slopes 376 and 376 having angles substantially corresponding to the slope 304 of the web 3a. The head portion 370 of the nut member 3B is provided with lateral holes 372 and 372 at positions outside the screw hole 33 in the width direction. Tightening piece 3A,

By passing the support shafts 8 and 8 through these holes and the lateral holes 372 and 372, they are connected to the nut member 3B. In this embodiment, the nut member 3B has a downward groove-shaped cross section, and the screw hole 33 is provided in a boss 373 formed on the wall forming the top surface of the head 370. In this embodiment, the support shafts 8,8
Although a pin is used and the end is crimped, the present invention is not limited to this, and various types such as a screw and a fastener pin can be used. In the assembled state, the lower end of the leg portion 371 extends to a level equal to or higher than the lower ends of the fastening pieces 3A, 3A, and as shown in FIG. Is in contact with the side surface 374 of the leg portion 371. As a result, the maximum opening angle of the tightening pieces 3A, 3A is restricted, and at the same time, when a strong tightening force acts on the tightening portions 31, 31, the load can be stably received.

As the restoring element 7, the tightening pieces 3A,
An example is one in which the mass of the tightening portion area of 3A is increased.
This can be realized by adding a weight element such as lead to the tightening portion 31, or by increasing the wall thickness of the inclined upper end portion (upright surface portion) of the web 3a. However, in order to obtain a more reliable restoring force, it is preferable to use an elastic body represented by a spring or rubber as the restoring element 7. A leaf spring is used in the embodiments of FIGS. This leaf spring 7 has a hole 70 in the center which is large enough to allow the screw shaft 21 of the screw member 2 to pass therethrough, and is mounted from the lower surface side of the leg portion 371 of the nut member 3B in a bent state and tightened. The pieces 3A, 3A are in contact with the inclined inner surfaces of the webs 3a, 3a. In this embodiment, the leg portions 371 form a pair in the front-rear direction with respect to the plane of FIG. If necessary, a cut-and-raised portion may be provided at the edge of the hole 70 to engage with the screw shaft 21.

The anti-floating element 6 is a means for preventing the tightening tool 3 from coming close to the seat portion side together with the screw member 2 without pressing when the main body 1 is pressed. In the example, an elastic member is used to cause the screw member 2 to function as a loosening stopper during tightening. This elastic member is interposed between the lower surface of the seat portion 12 and the head portion 370 of the nut member 3B, and pulls the nut member 3B toward the opposite seat portion by the repulsive force. As a result, the screw member 2 is always stably seated on the seat portion 12, and the tightening tool 3 is also held so as not to change its direction. Do more. A rubber or plastic tube or a bellows tube can be used as the elastic member, but a disc spring or a coil spring is generally suitable, and the boss 373 can be used for positioning when assembling the elastic member. it can. Elastic member is tightening tool 3
It may be used as an independent component. However, more preferably, the fastener assembly is preassembled so as not to be separated into the fastener 3. As this means, the tip of the elastic member may be joined to the upper surface of the nut member 3B by spot welding or the like, but as a simpler method, in this embodiment, a plurality of protrusions 375 for preventing slipping are provided on the outer periphery of the boss 373. It is provided. In the case of this structure, the tip end of the elastic member may be rotated clockwise while the tip end of the elastic member is inserted under the protrusion 375. With this, the tip end of the elastic member is the nut member head of the base of the boss 373. The elastic member can be integrated with the tightening tool 3 because it is seated on the upper surface of the part and a part rearward of the tip part is hooked under the protrusion 375.

9 and 10 show another embodiment of the main body 1 according to the present invention. 9 (a) and 10 (a), the guide portion 122 directly descends from the front end of the seat portion 12, and the bent portion 122 as shown in FIGS. 1 to 5 is not provided. In the embodiment shown in FIGS. 9B and 10B, the guide portion 122 is omitted. This can be applied when the spring force of the elastic member as the floating prevention element 6 is strong. In the second and third embodiments, the tightening tool 3 is suspended closer to the seat portion 12 than in the first embodiment, so that the height of the entire fixing tool can be reduced. The ribs 100, 100 are preferably provided on the top extension lines of the protrusions 30, 30 of the fastener 3.

There is. In FIG. 13B, a cancel type spring having several turns in the center is used as the restoring element 7, and both ends are fixed to the flange surface above the mounting position of the support shafts 8, 8. When the restoring element 7 is attached between the flanges, it may be provided on only one side of the fastening pieces 3A, 3A as shown in the drawing, or may be provided on both sides. It goes without saying that a tension spring may be used and passed through the lower end portion of the nut member 3B and passed to the web of the left and right tightening pieces 3A, 3A to fix both ends to the web. (4) The fixing method using a spring as the restoring element 7 is arbitrary, and may be stopped by elasticity and friction as shown in FIGS. 5 and 12. As shown in FIG. 15, holes 311 are formed in the webs 3a, 3a.

Instead of this, welding may be used, or in the case of FIG. 13, a cut-and-raised piece may be provided on the flange to hook the spring end portion, or a small hole may be provided in the flange to attach the spring end portion to this. You may hang it. (5) The left and right tightening pieces 3A and 3A do not necessarily have to have the same width. As shown in FIGS.
The widths of A and 3A may be different. In this case, the left and right tightening pieces 3A, 3A are preferably connected at one common fulcrum. That is, the fastening pieces 3A, 3A are the flanges 3
b, 3b are combined with the nut member 3B so that they overlap each other, and the nut members 3 are supported by the support shafts 8, 8.
B is pivotally supported. (6) Support shafts 8 and 8 are tightening pieces 3A and 3A and nut member 3B.
It is not limited to the case of penetrating in the assembled state. That is, as shown in FIGS. 14 to 18, the support shafts 8 and 8 are provided on the nut member 3B in advance, and the support shafts 8 and 8 simultaneously support the fastening members 3A and 3A when the nut members 3B are assembled. You may allow it. If this mode (6) is adopted, the fastener 3 can be easily assembled without using a special machine or jig. This is a tightening piece 3

Further, in place of this, a resistor such as a resin having a relatively weak adhesive force which is destroyed when the screw member is rotated is provided between the screw shaft 21 and the through hole 120 or between the screw head 20 and the seat upper surface. It may be obtained by filling. Needless to say, FIG. 20 and FIG.
In, the main body 1 and the tightening tool 3 include all of the above-described aspects except the configuration of the floating prevention element 6.

FIG. 22 shows a second embodiment of the present invention. In this embodiment, the seat portions 12, 12 are provided at both ends of the holding portion 10.
Is provided, and an assembly including a screw member 2, a tightening tool 3, and a floating prevention element 6 is attached to the seat portions 12 and 12, respectively. FIG. 21 shows a third embodiment of the present invention. In this embodiment, in addition to the structure of the second embodiment, a plurality of pipes (cables are shown in the drawings) 5 and 5 can be fixed at the same time. That is, the holding portion 10 is composed of the curved portions 10a on both sides, and the linear portions 10b connecting the curved portions 10a, and the concave arc surfaces 10 are formed on both sides in the main body width direction of the region included in the linear portions 10b.
The projecting pieces 10d having c and 10c are connected in series. The two projecting pieces 10d on both sides in the width direction of the main body are bent downward at right angles to the main body to form a pair of spacer portions.
Then, the arcuate surfaces 10c, 10c of the respective projecting pieces on both sides in the width direction and the curved portion 10a are paired to form a holding portion conforming to the cross-sectional shape of the conduit 5. The number of the projecting pieces 10d is not limited, and three conduits can be fixed by forming two in the length direction of the straight portion 10b, and four conduits can be fixed by forming three. it can. In the second and third embodiments, the floating prevention element 6 shows an example in which an elastic member is used, but of course the invention is not limited to this, and FIGS.
It is possible to employ various aspects such as those exemplified in. Further, the tightening tool 3 may have any of the configurations shown in FIGS. 6 to 8 or the configurations shown in the above (1) to (7).
Further, the form of the seat portion of the main body may be any of FIG. 2, FIG. 9 and FIG.

In any of the embodiments, the main body 1
The holding portion 10 may have an adhesive surface 9 for the pipes 5. As a method for obtaining the adhesive surface 9, there is a mode in which an adhesive layer or an adhesive layer is provided on the inner surface of the holding portion 10, as shown in FIG. In addition, instead of this, a mode in which it is magnetized by a magnetizing means may be mentioned. The latter is suitable if the body 1 is made of a ferromagnetic material. In the former case, it is convenient to use double-sided adhesive tapes with release paper. When such an adhesive surface 9 is provided, the main body 1 does not fall alone when fixing the pipes 5 with the inlet groove 42 of the groove-shaped rail 4 facing downward, so that safety can be improved. Further, the groove-shaped rail 4 which is a target of the present invention is not limited to the groove-shaped rail 4 in which the inlet groove walls 40, 40 hang vertically. Top wall 4 as shown in Figures 28 and 29
The grooved rail 4 of the type in which the inlet groove walls 40, 40 slant down from c, 4c, or the inlet groove walls 40, 40 as shown in FIG.
Is also applicable to the horizontal type grooved rail 4. Figure 2
When it is used for the groove-shaped rail 4 such as 8, 29, the tightening portions 31, 31 of the tightening tool 3 are not horizontal as described above and correspond to the inclination of the inlet groove walls 40, 40 as shown in FIGS. 30 and 31. It may have a different tilt angle.

Further, according to the present invention, temporary holding is performed by an operation of holding the main body 1 by hand and bringing it closer to the grooved rail 4. Therefore, as shown in FIGS. 2 and 3, it is also preferable to provide the anti-slip 123 by providing unevenness or protrusions on the outer surface of the holding portion 10 or further on the outer surface of the guide portion 122 or the bent portion 121. It is generally sufficient that the opposite seat side of the holding portion 10 extends to the height level of the seat portion 12, but in some cases, it may extend downward beyond the height level of the seat portion 12. In that case, the extension portion must be narrower than the inlet groove width W ₁ of the groove-shaped rail 4, and contacts the bottom of the groove-shaped rail 4 before holding the pipes 5 in the holding portion 10. Must not be of such length. When the fastening pieces 3A, 3A are made of plastic, the fastening pieces 3A, 3A may be connected to each other between the flanges or the webs by a compressible connecting portion. In this case, the connecting portion can function as a restoring element. The present invention has a structure in which a leg portion extending obliquely downward is continuously provided to a holding portion on the side opposite to the seat portion as a main body 1, and a locking portion protruding to both sides in the width direction is provided at a lower end of the leg portion. It is possible to use one. However, in this case, when fixing the piping, insert the leg into the grooved rail,
It is necessary to perform an operation of locking the groove-shaped rail by the locking portion. However, the operation of pressing and rotating or pressing the screw member for temporary fixing is unnecessary.

[0025]

Next, the operation of the embodiment of the present invention will be described. First, the assembly of the fixture according to the present invention will be described. When the nut member 3B has a protrusion 375 as shown in FIGS. 1 to 8, 11 to 12, and 16 to 18, the elastic member 6 serving as a floating prevention element is fastened by the protrusion 375. The fastener 3 is an assembly including the elastic member 6. Therefore, the upper portion of the elastic member 6 is applied to the lower surface of the seat portion 12 so as to be concentric with the through hole 120 of the seat portion 12, and the screw shaft of the screw member 2 penetrates the through hole 120 to screw the nut member 3B. The screw member 2 may be rotated in accordance with the hole 33 and screwed in until a predetermined length, for example, the tip of the screw shaft reaches the lower end portion of the nut member 3B. As a result, the fastening tool 3 rises, and the elastic member 6 is compressed accordingly, and a predetermined pressing force is applied to the fastening tool 3. Therefore, the assembly is very simple. When the nut member 3B as shown in FIG. 19 is used, the tightening tool 3
The lower end of the elastic member 6 is fitted around the boss 373 of the nut member 3B, and the elastic member 6 is inserted into the through hole 12 of the seat portion 12 in this state.
It is applied to the lower surface of the seat portion 12 so as to be concentric with 0. Subsequent operations are the same as those described above. In this assembled state, except for the case where the body 1 of the types shown in FIGS. 9 (b) and 10 (b) is used, part of the protrusions 30, 30 of the fastener 3 is positioned higher than the lower end of the guide portion 122. Reach the level. Therefore, even if the fastener 3 is touched with a hand or another article, the rotation of the fastener 3 is restricted by the contact with the guide portion 122.
As shown in FIG. 3 and FIG. 4, the tightening tool width direction is maintained in a relationship orthogonal to the inlet groove 42 of the groove-shaped rail 4. Also, the screw member 2
Is not rotated and is kept at the specified screw length. When the type of floating prevention element of FIG. 20 or FIG. 21 is used, the screw shaft 21 is inserted into the through hole 120 of the seat portion 12, and then the fastener 3 is preferably screwed onto the screw shaft 21. After that, the screw shaft 21 may be laterally fitted.

Next, the work of temporarily fixing the pipes 5 will be described. At the time of this temporary fixing, the pipes 5 are crossed over the ceiling wall 4c of the groove-shaped rail 4 as shown in FIGS. 1 to 3, and in this state, the holding portion 10 is positioned directly above the pipes 5. As described above, the main body 1 may be held in hand and the main body 1 may be pushed down as it is. This operation is easy because of the slip stopper 123. In this way, the holding portion 10 starts to approach the pipes 5 and at the same time, the fastener 3 suspended under the seat portion 12
Is an inclined surface 304, 30 at the bottom of the fastening pieces 3A, 3A.
4 is in contact with the openings of the inlet groove walls 40, 40, and the main body 1 continues.
Of the inclined surfaces 304, 304 (webs 3a, 3
a) is pressed from the left and right by the inlet groove walls 40, 40. Therefore, as shown in FIG. 24, the tightening pieces 3A, 3A tilt inwardly against the force of the restoring elements 7, 7 with the support shafts 8, 8 as fulcrums, and the inclined surfaces 304, 304 have the inlet groove walls 40. ，
The whole descends while shrinking so as to contact 40. At this time, the force of the floating prevention element 6 exceeds the restoring force of the restoring elements 7 and 7, and the lifting force acting on the tightening pieces 3A and 3A is canceled, so that the tightening pieces 3A and 3A smoothly descend while narrowing. You can Still, the pressing of the main body 1 continues, and the bent portion 122 connected to the seat portion 12 has the groove-shaped rail top wall 4c,
4c is reached, and as shown in FIG.
A, 3A inclined surfaces 304, 304 are inlet groove walls 40, 40
After passing under the lower surfaces 41, 41, the narrowing action by the inlet groove walls 40, 40 is released. Therefore, the action of the restoring elements 7, 7 causes the fastening pieces 3A, 3A to abduct with the support shafts 8, 8 as fulcrums, and the fastening portions 31, 31 pass under the lower surfaces 41, 41 of the inlet groove walls 40, 40. . At this time, the tightening portion 31,
Adjacent to 31 is a protrusion 30, 30 that is higher than these, and the radius of gyration of this protrusion 30, 30 is
It is larger than the turning radius of 1. Therefore, the protrusions 30, 30
The stopper surfaces 300, 300 at the tips of the inlet groove walls 40, 4
The stopper surfaces 300, 300 come into contact with the inlet groove walls 40, 40 with the snaps or come very close to the inlet groove walls 40, 40 at the same time when the tightening portions 31, 31 become horizontal toward 0.

In the main body 1, the lower end of the bent portion 122 in the embodiment shown in FIGS. 1 to 5 and the lower surface of the seat portion 12 in the embodiment shown in FIGS. 9 and 10 are grooved rail top walls 4c, 4c.
The holding portion 10 holds the pipes 5 at this time when the lowering is automatically stopped. Tightening piece 3 as described above
When A and 3A are abducted, the lower ends 306 and 306 of the webs of the tightening pieces 3A and 3A are in contact with the leg side surfaces 374 and 374 of the nut member 3B and are in the maximum expanded state. 26 and FIG. 28, the positions are approached to the lower surfaces 41, 41 of the inlet groove walls 40, 40, and the temporary fixing state is established. In this state, even if the main body 1 is lifted in the direction away from the groove-shaped rail 4, the tightening portion 3
The main body 1 cannot be disengaged from the groove-shaped rail 4 because the fastening pieces 3A, 3A are kept in the expanded state by the contact of the lower portions 41, 41 of the inlet groove walls 40, 40 with the fastening pieces 1, 31. Further, even if the main body 1 is moved in the width direction of the groove-shaped rail, the stopper surfaces 300, 300 at the tips of the protrusions contact the inlet groove walls 40, 40, and
In the main body embodiments other than (b) and FIG. 10 (b), the guide portion 122 also abuts the inlet groove walls 40, 40, so that the main body 1 does not laterally shift. However, the main body 1 can move freely in the direction along the rail inlet groove 42, and at this time, the fastening pieces 3A, 3A have a predetermined width W as shown in FIG. There are two 300 in each of the fastening pieces 3A, 3A. Therefore, the main body 1
Even if the tightening portions 31 and 31 are moved, the inlet groove walls 40 and 40
Of the lower surfaces 41 and 41 are maintained orthogonal to each other. Further, the guide portion 122 exerts a good guide action. Therefore, the pipes 5 can be smoothly moved in parallel while being held by the main body 1, and the position adjustment is easy. As described above, during the temporary fixing work, it is not necessary to hook the main body 1 on the groove-shaped rail 4 in advance, and it is not necessary to tilt the main body 1 in that state to insert the pipes 5 into the holding portion 10, Further, it is not necessary to touch the screw member 2. Therefore, the work is extremely simple and can be done by anyone without mistake.

Next, the case where the main fixing is performed will be described.
After the position adjustment is performed as described above, if the screw member 2 is rotated, the stopper faces 300, 300 of the tightening pieces 3A, 3A are rotated.
Is in contact with or close to the inlet groove walls 40, 40,
Demonstrate good guide function and rotation control function. Further, the guide portion 122 also exhibits a guide function and a rotation restriction function at a position displaced by 90 degrees from the stopper surfaces 300, 300. Since the head of the screw member 2 is in contact with the seat, the screw member 2 can be easily rotated without wobbling. When the anti-floating element 6 is an elastic member, the tightening tool 3 vertically rises against the elasticity of the elastic member 6 in a state of being orthogonal to the groove rail, and the tightening portions 31 and 31 are lower surfaces of the inlet groove walls 40 and 40. It is close to 41 and 41 and is strongly tightened. At this time, the lower ends 306, 306 of the webs of the tightening pieces 3A, 3A are attached to the side surface 37 of the leg portion of the nut member 3B.
Since it is received by 4, 374, it can withstand a strong torque, and the fastening pieces 3A, 3A can be kept in a stable state without opening beyond the set angle. Even when the nut member 3B has a groove-shaped cross section, it can withstand a strong torque because it receives a load in the direction perpendicular to the plate thickness. As a result, the pipes 5 are strongly pressed against the groove-shaped rail while being held by the holding portion 10, and are permanently fixed as shown in FIGS. 27 and 29.
At this time, the elastic member 6 is compressed between the seat portion 12 and the nut member 3B, and the screw member 2 is strongly pulled downward via the tightening tool 3. Therefore, thereafter, the tightened and fixed state does not loosen.

When the pipes 5 are made of a soft material and have some elasticity, when the pipes 5 are held by the holding portion 10 by lowering the main body 1 as described above, the pipes 5 are held. No. 5 is once compressed in the radial direction and then restored. For this reason, the entire body is lifted by the amount of restoration, and the tightening portions 31, 31 contact the lower surfaces 41, 41 of the inlet groove walls 40, 40,
It can be temporarily fixed without rattling. When the adhesive surface 9 is provided on the inner surface of the holding portion of the main body 1, the inlet groove 42
At the time of temporarily fixing the pipes 5 to the groove-shaped rail 4 facing downward, since the pipes 5 are bonded and integrated with the holding portion 10, there is no fear of dropping. In the case of FIGS. 22 and 23, the pressing operation of the main body 1 simultaneously brings the left and right tightening tools 3, 3 into the temporarily fixed state due to the above-described behavior, which is safer and more reliable, and in the case of FIG. 23, In addition to this, the plurality of pipes 5 and 5 can be temporarily fixed at a time while being arranged at regular intervals, so that the efficiency can be significantly improved.

30 and 31 show the present invention in which the inlet groove wall 40,
40 shows the behavior of the tightening tool 3 when applied to the slanted grooved rail 4, and it is narrowed as shown in FIG. 30, and the slanted surfaces 304, 304 have passed the tips of the inlet groove walls 40, 40. It momentarily abducts and becomes a temporarily fixed state as described above. FIG. 29 shows the fixing completion state. In the case of the grooved rail 4 of FIGS. 30 and 31, the tightening portions 31, 3 are
If 1 is not horizontal but is directed upward at an angle close to the inclination angle of the inlet groove walls 40, 40, it can be more firmly fixed. FIG. 32 shows the fixing state when the present invention is applied to the grooved rail 4 in which the inlet groove walls 40, 40 are horizontal.
In this case, the fastener 3 is deflated by contact with the front ends of the inlet groove walls 40, 40.
