Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener for fastening metal fittings.

[0002]

2. Description of the Related Art When fixing a girder-shaped member for forming a raceway or a duct in an electric circuit work, it is necessary to fasten and fix a member to be fixed to a groove-shaped rail or the like with a metal fitting. As such a fastening means,
Conventionally, various things have been proposed, for example, using a blade plate-shaped nut and screwing a bolt passing through a seat of a metal fitting main body through a female screw hole at the center of the nut.

[0003] Such conventional fasteners exhibit a considerable effect compared to conventional fasteners in which parts are separated. However, the conventional fastening fixture is troublesome because the blade-shaped nut must be adjusted to a predetermined direction (longitudinal direction is parallel to the rail groove) before use. Therefore, there is a problem in that the direction of the wing plate-shaped nut tends to change carelessly.

Further, after inserting the wing plate nut into the groove of the rail, the screw head must be operated to rotate the wing plate nut by 90 degrees so as to be orthogonal to the groove rail. At this time, if the bolt is erroneously turned to the loose side, the plate nut is detached from the bolt and falls into the grooved rail. For this reason, there has been a serious problem that a large number of work errors occur, and this kind of work for performing a large number of tightening and fixing operations requires a long working time and a low efficiency.

[0005] Further, in the conventional fastening device, it has been essential to stop rotation by bringing both ends in the longitudinal direction of the blade-shaped nut into contact with the inner wall of the flange of the grooved rail. For this reason, first, the dimensions of the blade-plate-shaped nut become long, and when the screw is tightened, it is likely to bend, and to prevent this, it is necessary to make the nut thicker. However, there is a problem that the device is large and heavy, and handling during transportation and work is troublesome.

Secondly, since the longitudinal end of the blade plate-shaped nut is brought into contact with the inner wall of the flange of the grooved rail, the method cannot be applied if the inner width of the grooved rail changes. Various types of plate nuts must be prepared according to the type of the inner width of the rail, which is uneconomical.
Since it cannot be used for a structure (hole type) having no walls on both insides other than the grooved rail, there is a problem that the use is limited.

Third, since the rotation is stopped by abutting the longitudinal ends of the vane plate-shaped nut on the flange inner wall of the grooved rail, the surface property of the flange inner wall of the grooved rail is greatly affected. If the inner wall of the flange of the receiving and grooved rail is rough or uneven,
It is not perpendicular to the longitudinal direction of the rail groove and is obliquely hooked, so that the screw cannot be rotated or the blade-shaped nut rises while being flat and oblique. As a result, the rail is fastened without securing the entrance groove wall of the groove-shaped rail and a sufficient tightening area, and is likely to be in an unstable or uncertain tightening state, and the reliability of the fixing performance is poor.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and the object thereof is to be achieved irrespective of the depth of the rail groove and the dimensions of the inner width of the flange. An object of the present invention is to provide a fastening fixture which can temporarily fix and fasten and fix a member to be fixed by an extremely simple operation, yet has a simple structure, is extremely small in size, and can realize low cost. Another object of the present invention is to provide a tightening fixture which can be applied not only to a grooved rail but also to a holed member having no wall therein.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a metal fitting body for fixing a solid object to a grooved rail or a member with a hole, and a screw having a shaft portion inserted through the metal fitting body. A fastening nut plate having a female screw hole to be screwed with a screw shaft portion, and an elastic member interposed between the fitting body and the fastening nut plate to bias the fastening nut plate 1 in a direction opposite to the fitting body. Wherein the fastening nut plate has a short side having a width w smaller than the width W1 of the entrance of the grooved rail or the holed member, and a length longer than the width W1 of the entrance but shorter than the inner width W2 of the grooved rail. L, and the fitting body faces the long side of the tightening nut plate in order to restrict the rotation of the tightening nut plate and allow only the movement parallel to the shaft of the screw. It is characterized by having a guide piece

[0010] The tightening nut plate is basically a single component, but in addition to a flat plate, a groove-shaped cross-sectional shape having a rising wall at a long edge or a short edge. Contains. In the case where the rising wall is provided in this manner, the strength is increased by the angle effect, so that a firm fixing can be achieved even if the thickness of the fastening nut plate is thin.

Preferably, the shaft of the screw has a retaining portion at the lower end. The retaining portion exerts not only the function of preventing separation from the fastening nut plate but also the function of setting the set position (the lower limit) of the fastening nut plate in cooperation with the elastic member.

In the present invention, the metal fitting main body having the guide vertical piece is not necessarily limited to a single body. That is, a first part having a seat to be seated on the grooved rail, and a second part combined with the first part, and a main part in which the second part contacts the seat. And a guide vertical piece bent and extended from the main part.

In this aspect, the main part of the second part has a rising portion corresponding to the thickness of the seat of the first part and a sandwiching piece extending horizontally thereafter. And a part that sandwiches the seat from above and below to integrate the second part with the first part.

In the present invention, the term "fixed object" is a concept including various members and members of various shapes and structures such as a girder material such as a main girder and a child girder, a partition plate, an outlet box, a separator and the like in an electric circuit work. . Therefore, the metal fitting body of the present invention includes various shapes and structures corresponding to the fixing object. However, in any case, the metal fitting main body engages with or is caught by the main part (hold portion) for fixing the object to be fixed to the grooved rail, the member with holes, or the like. It has a portion that meshes and joins.

[0015]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 5 show a first embodiment in which the fastening fixture according to the present invention is applied to a grooved rail. The first embodiment shows an example in which the present invention is applied to a steady fitting for a duct (girder member) A arranged crosswise on the groove-shaped rail 2. Although only one grooved rail 2 is shown in the drawing, many are arranged in parallel at predetermined intervals and are supported from the ceiling by hanging brackets. As shown in FIG. 1 and FIG. 2A, the groove-shaped rail 2 has a bottom wall 203,
Side walls 202, 202 rising from both ends in the width direction.
And a pair of entrance walls 201, 201 extending inward from the tops of both side walls 202, 202 to form an entrance groove 200. In this example, the entrance walls 201, 201 are bent obliquely from the tops of the side walls. However, as will be described later, they may be bent so as to extend horizontally from the tops of the side walls 202, 202, or the side walls 202, 202. May be bent horizontally from the top and further bent at a right angle from the bent end.

The duct A as an object to be fixed is made of extruded material, and is provided at the lower end of the back surface A1 with the entrance wall 20 of the grooved rail 2.
1,201 have a bottom part A3 placed in a cross shape, and a top part has a top part A2 to be held by the metal fitting body 3. The bottom portion A3 and the top portion A2 are portions bent at right angles to the back surface A1.

The fastening fixture includes a fitting body 3 and a screw 4
And a tightening nut plate 1 and an elastic member 5. The fastening nut plate 1 is usually made of a ferrous or non-ferrous metal, and has a rectangular shape or a similar shape (e.g., an ellipse) when viewed in plan by a short side and a longer side having a relatively larger dimension. And oval type).
The width w (dimension of the short side) w of the tightening nut plate 1 is shown in FIG.
2 is smaller than the width W1 of the entrance groove 200 of the groove-shaped rail 2 and, as shown in FIG.
Is longer than the width W1 of the entrance groove 200 of the channel-shaped rail 2 but shorter than the inner width W2 of the channel-shaped rail, that is, the distance between the inner surfaces of both side walls. The width w and the length 1 are the same in each example described later. At the center of the tightening nut plate 1, there is provided a female screw hole 10 through which a screw shaft portion 42 inserted through a through hole of a seat of the metal fitting body 3 is screwed. Ridges 12 are formed.

The metal fitting body 3 has a rising portion 30 to be in contact with the back surface A1 of the duct A and a bent portion formed at the top of the rising portion 30 so as to be hooked to the top A2 of the duct A.
And a seat portion 32 bent from the lower end of the rising portion 30 in a direction opposite to the hook portion 31. The seat portion 32 is a portion that sits on the entrance walls 201 of the grooved rail 2.

As shown in FIG. 2A, the seat portion 32 has an upper plate portion 320 and a lower plate portion 321 which is inverted and bent from the tip of the upper plate portion 320 and overlaps the upper plate portion 320. The upper plate 320 and the lower plate 321 are provided with through holes for inserting the shaft 42 of the screw 4.

At the lower surface plate portion 321, a guide vertical piece 33 extending parallel to the screw shaft portion 42 is provided at a position forward of the base end of the seat portion 32 (the position where the rising portion 30 starts). Have been. The hanging piece 33 for the guide is a fastening nut plate 1.
Extends in such a manner as to directly face the long side 100 of the tightening nut plate 1 and has a lower end equivalent to the tip of the shaft 42 of the screw 4 so as to restrict horizontal rotation of the screw 4 and allow movement only in the direction parallel to the shaft of the screw. Level or a slightly longer level.

In order to restrict the horizontal rotation of the tightening nut plate 1, the guide vertical piece 33 has a relatively wide band-like shape and has a width at least larger than the diameter of the shaft of the screw. Is preferred. However, the guide piece 33
Need not necessarily be a single strip, but may be bifurcated. Although not shown, the guide vertical piece 33 may have a portion bent at a right angle from the lower end.

An elastic member 5 for urging the fastening nut plate 1 in a direction opposite to the seat portion is interposed between the seat portion 32 and the fastening nut plate 1. The elastic member 5 may be a cylinder made of rubber or plastic, but usually a drum-shaped coil spring is used and is arranged concentrically with the screw shaft. By using this elastic member 5, it is possible to keep the fastening nut at a predetermined distance from the metal fitting body without causing the fastening nut to move before full-scale fastening and fixing. In addition, since the head of the screw does not float at the time of fastening and fixing, the turning operation of the screw can be performed smoothly. Further, after the tightening, the pressing force of the elastic member acts on the tightening nut, so that the screw does not loosen even by vibration or the like.

The screw 4 is provided with a retaining portion 40 at its lower end to prevent separation from the tightening nut plate 1 and to set a set position (a lower limit) of the tightening nut plate 1. In this example, the retaining portion 40 has an enlarged-diameter portion formed at the lower end of the screw shaft portion 42 by caulking or local ridge processing. The integrally formed retaining portion may be provided after the screw 4 is threaded through the fastening nut plate 1. Guide piece 33
Has a portion bent at a right angle from the lower end, the bent portion comes into contact with the lower surface of the tightening nut plate 1 and the setting position is determined, so that the formation of the retaining portion is omitted. You can also.

The use and operation of the first embodiment will be described.
In a normal state, the fastening nut plate 1 is positioned near the lower end of the screw 4 by the retaining portion 40 and is pressed by the elastic member 5 in the direction opposite to the seat. Further, since the long side (side edge) 100 of the tightening nut plate 1 is opposed to the guide vertical piece 33 descending from the seat 32, the long side 100 is in the width direction of the seat 32 as shown in FIG. It is held so as to be parallel. Therefore, even if the screw 4 is rotated or another object collides with the fastening nut plate 1, the posture of the fastening nut plate 1 is not changed at all.

In use, the metal fitting body 3 is gripped by hand and turned sideways as shown in FIG. 2 (a), that is, the seat 32 is oriented so that the width direction thereof intersects the entrance groove 200 of the channel-shaped rail 2. In this case, the long side 100 of the tightening nut plate 1 automatically becomes parallel to the inlet groove 200. Therefore, if the metal fitting main body 3 is lowered as it is, the tightening nut plate 1 becomes the grooved rail 2 as shown in FIG. Is inserted into the inside through the inlet groove 200. At the same time, while holding the metal fitting body 3 by hand and rotating it 90 degrees clockwise or counterclockwise as shown in FIGS. 3A and 3B, the guide vertical piece 33 and the long side 100
The relative orientation of the fastening nut plate 1 with respect to the fitting main body 3 does not change due to the relationship (1), so that the fastening nut plate 1 rotates together with the fitting main body 3 so that the long sides 100 of the fastening nut plate 1 define the inlet grooves 200. Below and orthogonally oriented.

FIGS. 4 (a) and 4 (b) show a state in which the rotation of the bracket main body 3 has been completed. Since the tightening nut plate 1 has a required distance between the entrance walls 201 and 201, FIG. The height of the metal fitting body 3 can be freely changed. Therefore, as shown by the imaginary line in FIG. 4A, the metal fitting main body 3 is lifted while approaching the duct A as an object to be fixed, so that the hooked portion 31 is engaged with the top A2 of the ladder-shaped duct A, and temporarily. A stop state can be obtained.

Then, the position of the duct A is appropriately adjusted, and the screw 4 is tightened with a tool T such as a screwdriver as shown in FIG.
When the head is rotated, the tightening nut plate 1 cannot rotate because the long side 100 abuts on the guide vertical piece 33 descending from the seat portion 32. While maintaining the perpendicular relationship with the inlet walls 201, 201, the ascending member rises along the guide vertical piece 33 against the urging of the elastic member 5 and makes strong contact with the lower surfaces of the inlet walls 201, 201, and the seat portion. 32 and is firmly fixed. After the tightening, the pressing force of the elastic member 5 acts on the tightening nut plate 1, so that the tightening nut plate 1 does not loosen due to vibration or the like.

In the present invention, the screw 4
The operation is very simple because there is no need to operate the nut, and the tightening nut plate 1 is rotated by 90 degrees relative to the metal fitting body 3 to rotate the nut plate 1 by contact with the inner width surface of the grooved rail 2. Instead of stopping, it is integrated with the metal fitting body 3 for rotation, and the change in the direction of the metal fitting body 3 is the change in the direction of the tightening nut plate 1 as it is, so that no operation error occurs.

Further, as described above, the rotation of the tightening nut plate 1 alone is restricted by the relationship between the long side 100 and the guide hanging piece 33 descending from the seat portion 32, and the tightening nut plate 1 can move only in the vertical direction. Therefore, the length 1 of the tightening nut plate 1 is shorter than the inner width W2 of the grooved rail 2 and may be a dimension that does not contact the side wall of the grooved rail at all. Therefore, regardless of the inner width dimension of the groove rail 2, the length 1 is equal to the inlet groove width W1.
The present invention can be applied to any grooved rail 2 as long as it is larger than the dimension of. At the same time, the metal fitting body 3 may be turned clockwise or counterclockwise in the temporary fixing, so that it is possible to freely cope with the situation of the fixed place.

Further, the height as the fastening means can be reduced, and the length of the screw 4 and the guide piece 33 corresponding to the depth H of the grooved rail 2 can be reduced.
As shown in (b), it is possible to freely cope with grooved rails having various depths H1 and H2.

FIGS. 6 and 7 show a second embodiment of the present invention. In this embodiment, a guide vertical piece 33 descending downward is formed at the tip of the seat 32 of the metal fitting body 3. Since other configurations are the same as those of the first embodiment,

0 and a width w smaller than a width W1 and an entrance groove 2 of the grooved rail 2.
The length l is larger than the width W1 of 00, but shorter than the inner width W2 of the grooved rail, as in the case of the previous embodiment. 8 and 9, the fastening nut plate 1 is not a flat plate, but has a pair of rising walls 13, 13 along a parallel long side 100, and has a groove-shaped cross section as a whole. In this way, even if a relatively thin material is used, the strength can be increased by the angle effect, and the area facing the guide vertical piece 33 can be increased. Regulations can be ensured.

A short tube portion 17 is formed in the bottom plate portion of the tightening nut plate 1 by burring or the like, and a female screw hole 10 is formed in the short tube portion 17. An end portion of the elastic member 5 is formed on the outer periphery of the short tube portion 17. A spring hook projection 171 is formed to lock the hook and prevent it from coming off. In this example, the short cylindrical portion 17 is formed upward. By providing the spring hook projections 171, the elastic member 5 and the fastening nut plate 1 can be made into one unit, so that the assembly of the fastening tool can be facilitated. Since other configurations are the same as those of the first embodiment, the same reference numerals are given to the same portions, and the description will use the description of the first embodiment.

According to the present invention described above, the guide main body 33 is provided with the guide vertical piece 33 so as to face the long side of the tightening nut plate 1 which is threaded through the screw 4 descending from the main body 3. Since the rotation is restricted and the movement only in the vertical direction is allowed, the direction of the bracket main body 3 always coincides with the direction of the tightening nut plate 1. By inserting the piece part 33 and the fastening nut plate 1 and changing the direction of the bracket main body 3 by 90 degrees, the fastening nut plate 1 can be temporarily fixed so as to be orthogonal to the inlet groove of the channel rail 2 or the like. In addition, the article can be easily and quickly fixed to the grooved rail 2 or the holed member 2 ′ having a desired depth and a desired inner width by a simple operation without a work error.

In addition, the width of the tightening nut plate 1 is smaller than the width W1 of the entrance groove 200 of the grooved rail 2 and the width of the entrance groove 2
Since it has a length l which is longer than the width W1 of 00 but shorter than the inner width W2 of the grooved rail, it can be compact and lightweight, easy to handle, and have high rigidity and strength. In addition, since the long side of the fastening nut plate 1 functions as a guide portion, the structure of the fastening nut plate 1 can be made compact and simple, and an inexpensive fastening tool can be obtained. Further, there is no restriction on the inner width of the grooved rail 2 and a single type of tightening fixture can be used, and even if the inner wall surface property of the grooved rail is any, the tightening nut plate 1 can be accurately adjusted.
