Mounting body for attachment to bolt body and nut body

A mounting body 100 in accordance with the invention is mounted to a bolt body from a side portion of the bolt body. The mounting body 100 is provided with a mounting portion 10 having an engagement portion 20 provided with an engagement projection 21 engaging with an outer thread of the bolt body, an opening portion 70 moving forward the bolt body into the engagement portion 20, and adjacent portions 30 arranged in a leading end side of the engagement portion 20. The mounting body 100 can be mounted to the bolt body by moving forward the bolt body from the opening portion 70 of the mounting portion 10, thereafter plastically deforming the engagement portion 20 so as to make the adjacent portions 30 relatively close to each other, arranging the engagement portion 20 along an outer surface of the bolt body, and maintaining a state in which the engagement projection 21 is engaged with the outer thread of the bolt body.

TECHNICAL FIELD

The present invention relates to a mounting body which can be mounted to a bolt body, and more particularly, a mounting body to a bolt body which can be easily and securely mounted to a position apart from an end portion of the bolt body.

BACKGROUND ART

Conventionally, when installing a cable rack (a receiving device) for arranging a wiring material and a piping material in a station or a plant, it is generally carried out to fix same to a bolt body suspended from a ceiling (or buried in the ground) by means of a nut. Further, in the case of installing various other plant materials in a building, the plant materials are fixed to a bolt body fixed to a construction thing of the building so as to install same.

In particular, in the case in which the plant materials are fixed to an intermediate position of the bolt body by the nut body, the fixation to the bolt body is achieved by clamping a connection portion to the bolt body on a subject to be installed such as the cable rack, the box or the like from front and rear sides (or from upper and lower sides) by a plurality of nut bodies. Specifically, as shown inFIG. 43, installation is achieved by clamping a steel product having an approximately L-shaped cross sectional shape between a pair of bolt bodies from upper and lower sides by two nuts, and mounting the cable rack on the L-shaped steel product.

However, in order to fix the placed subject to the intermediate position of the long bolt body, it is necessary to rotate and move forward the nut body at a significant distance from an end portion of the bolt body. Accordingly, it is very difficult to install the placed subject.

However, in order to fix the placed subject to the intermediate position of the long bolt body, it is necessary to rotate and move forward the nut body at a significant distance from an end portion of the bolt body. Accordingly, it is very difficult to install the placed subject.

In accordance with the present invention, since the mounting portion is integrally provided in the connection portion to the bolt body in the placed subject, such as the cable rack, the box and the like, it is only possible to mount the bolt body by applying the mounting portion from a side portion of the bolt body and applying a simple force.

On the other hand, the conventional nut is screwed forward in an axial direction of the bolt body by rotating and moving same forward from one end of the bolt body. Here, in the case that the nut body or the like has already been screwed and fixed to a predetermined position and the other positions in the bolt body, it is impossible to rotate and move forward a new nut body into the fixed interval.

Accordingly, as shown inFIG. 41, there has been proposed an interposition type nut manufactured by SLIP ON LOCK NUT CO., LTD., (U.S.A.). The interposition type nut is constituted, as shown inFIG. 41, by a pair of nut bodies, and each of a pair of nut bodies is provided with an opening in one side. Further, the respective nut bodies are pressed to each other by rotating the respective nut bodies in opposite directions, as shown inFIG. 42, after moving forward the bolt body from the opening, whereby the respective nut bodies stay in the positions.

Therefore, in accordance with the technique on the basis of the interpositions type nut, since it is not necessary to rotate and move forward the nut to the bolt body from the end portion thereof, it is possible to horizontally mount same from any positions of the bolt body. Further, this structure can be applied to a position where both ends of the bolt body have been already supported, a position where the mounting position is frequently moved, and a position where the nut fails to be installed until after the execution. Further, as shown inFIG. 43, the placed subject can be installed with respect to the bolt body when the nut body has been already installed at a lower end and an upper end is fixed to the ceiling by mounting the nut body to an intermediate position.

However, in the interposition type nut mentioned above, since an extremely high accuracy is required in a stage of manufacturing, the nut and the structure of the nut is complex, a high unit price per one set of nut mentioned above results. Accordingly, in the case that the interposition type nut mentioned above is frequently used, the implementation cost is increased. Therefore, the interposition type nut is actually used on in a specific position, compensating for the conventional inexpensive nut. Thus, it is necessary to use the conventional inexpensive nut and the expensive interposition type nut together.

DISCLOSURE OF THE INVENTION

The present invention is made by taking the various problems in the prior art mentioned above into consideration, and inexpensively provides a mounting body100and a nut body110which can be easily mounted from a side portion of a bolt body300. A description will be given of the mounting body100.

First, the mounting body100in the present invention comprises a receiving device120for a wiring material and a piping material (refer toFIG. 29), a box130for a wiring material and a piping material (refer toFIG. 35), a suspended metal fitting140of the receiving device120(refer toFIG. 37), or the like. A mounting portion10is provided in the mounting body100, and the mounting body100is mounted to an outer surface of the bolt body300by the mounting portion10. As discussed later, in the present invention, a nut body110(refer toFIGS. 1 to 20) is included in the mounting body100. In other words, the nut body110corresponding to the mounting body100can be structured by independently constructing a structure corresponding to the mounting portion10in the receiving device120or the like.

The mounting portion10mentioned above is provided as a part of the mounting body100corresponding to the mounting subject. The mounting portion10is provided with an engagement portion20, an adjacent portion30provided in a leading end of the engagement portion20and an opening portion70moving the bolt body300into the engagement portion20. An engagement projection21, engaging an outer thread310of the bolt body300, is provided in a protruding manner on one surface of the engagement portion20.

Further, the mounting portion10in the present invention is moved close to the bolt body300by applying the engagement portion20of the mounting portion10to the outer surface of the bolt body300corresponding to the mounted subject from a side portion thereof. Thereafter, the engagement portion20is plastically deformed by relatively moving the adjacent portions30close to each other, whereby the engagement portion20is arranged along the outer surface of the bolt body300. It is possible to maintain a state in which the engagement projection21, protruding on the surface of the engagement portion20, is engaged with an outer thread310of the bolt body300by arranging (closely attaching) the engagement portion20along the outer surface of the bolt body300.

Thus, it is possible to engage the mounting portion10with the outer thread310of the bolt body300, and it is possible to mount the mounting body100corresponding to the mounted subject to the outer surface of the bolt body300.

In accordance with the present invention, it is possible to maintain a state in which the engagement projection21is engaged with the outer thread310of the bolt body300only by plastically deforming the engagement portion20in connection with the mounting portion10. It is also possible to mount the mounting body100to the bolt body300.

In this case, as mentioned above, since the engagement portion20is plastically deformed after being applied and arranged from the side portion of the outer surface in the bolt body300, it is possible to mount the mounting body100, regardless of whether mounting occurs at the end portion or the intermediate portion of the bolt body300.

Next, a description will be first given of the engagement portion20with respect to the structure of the mounting portion10.

The engagement portion20is structured such that the engagement portion20itself is plastically deformed, thereby being brought into contact with (closely attached to) the bolt body300in connection with the mounted subject so as to clamp the bolt body300. However, the specific structure of the engagement portion20is not particularly limited. There can be considered, for example, a structure in which a flat plate is bent and a pair of band-shaped members are provided so as to stand face to face, as shown inFIG. 3or8, or a structure in which a base member of the mounting body100is cut and raised and a pair of band-shaped members are provided so as to stand face to face, as shown inFIG. 29. In this case, the engagement portion20shown inFIG. 29includes a flat surface shape portion formed in a side of an opposite opening portion70, in addition to a pair of band-shaped members. In other words, the engagement portion20in the present invention is not limited to a pair of band-shaped members, but includes a portion which is held between the respective band-shaped members so as to be brought into contact with the bolt body300.

The opening portion70is formed between a pair of band-shaped members. The bolt body300, in accordance with the mounted subject, is moved forward from the opening portion70so as to be plastically deformed. When the engagement portion20is formed by providing a pair of band-shaped members so as to stand face to face as shown inFIG. 25, it is further preferable to closely attach the engagement portion20to the entire outer surface of the bolt body300in accordance with the mounted subject, as shown inFIG. 26, after plastically deforming the engagement portion20. In order to achieve same, it is contemplated that the entirety of the pair of band-shaped members is formed in approximately the same size as an outer peripheral dimension of the bolt body300.

Further, the engagement portion20is provided with an engagement projection21engaging with the outer thread310of the bolt body300in a protruding manner, and the adjacent portion30is formed by folding the leading end.

In the case which the bolt body300is clamped by bringing the engagement portion20into contact with the bolt body300(closing and/or attaching the engagement portion20to the bolt body300), the engagement portion20is plastically deformed, and the engagement projection21provided in the engagement portion20in a protruding manner is engaged with the outer thread310of the bolt body300. The engagement projection21is engaged with the outer thread310of the bolt body300, whereby it is possible to prevent the mounting body100corresponding to the mounted subject from being displaced with respect to the axial direction of the bolt body300.

The engagement portion20may employ any material so long as the material can be plastically deformed itself. Specifically, it is considered to be preferable that the engagement portion20is formed by a metal (a steel plate) and a deformed state can be maintained after being deformed. Accordingly, it is possible to maintain the state in which the engagement projection21is engaged with the outer thread310of the bolt body300mentioned above, by plastically deforming the engagement portion20, and it is possible to continuously mount the mounting body100corresponding to the mounted subject to the bolt body300.

It is possible to plastically deform the engagement portion20, mentioned above, by relatively moving the adjacent portion30provided in the leading end side of the engagement portion20close to each other. The adjacent portion30may be formed as a grip piece corresponding to a gripping portion at a time of plastically deforming the engagement portion20. As shown inFIGS. 25 and 26, it is possible to easily, plastically deform the engagement portion20along the outer surface of the bolt body300by gripping the adjacent portion30by a pitching tool P, such as a pincher or the like, at a time of plastically deforming the engagement portion20, and clamping this at a breath (or step by step).

Further, the adjacent portion30, mentioned above, may be previously provided so as to protrude toward a slightly leading end direction (a lower side inFIG. 27) of the engagement portion20, as shown inFIG. 27. By arranging the adjacent portion30so as to incline to the slightly leading end direction of the engagement portion20, it is possible to more easily clamp by means of the pinching tool P.

In this case, the engagement projection21, mentioned above, is engaged with the outer thread310of the bolt body300, and the following structure can be considered as a specific structure thereof. The structure is made such that one or two or more projections (the engagement projection21) that are provided in a protruding manner on the contact surface of the outer surface of the bolt body300in accordance with the mounted subject, and the projection is engaged with the outer thread310of the bolt body300. The structure may be made such that a groove22is spirally inscribed on the contact surface mentioned above, and the spirally inscribed surface is engaged with the outer thread310of the bolt body300. As shown in each of the drawings, since the entire spirally inscribed surface can be engaged with the outer thread310of the bolt300by spirally inscribing the groove22on the engagement surface, it is possible to strongly and securely engage the engagement portion20with the bolt body300. At this time, it is considered to be preferable that the groove22is spirally inscribed at a pitch corresponding to the outer thread310of the bolt body300in accordance with the mounted subject. When employing the structure mentioned above, since the entire spirally inscribed surface is engaged with the outer thread310of the bolt body300, it is possible to effectively prevent the mounting body100from being displaced in the axial direction of the bolt body300.

The time when the engagement projection21is engaged with the outer thread310of the bolt body is not limited to a time before the engagement portion20is plastically deformed or a time after the engagement portion20is plastically deformed.

For example, when the mounting body100(the nut body110) shown inFIG. 1is brought into contact with the outer surface of the bolt body300, as shown inFIG. 25, the engagement projection21, provided in a protruding manner in an inner side of a portion (an upper half circle portion), corresponding to an arc in the mounting body100(the nut body110), is engaged with the outer thread310of the bolt body300. In other words, the mounting body100(the nut body110) shown inFIG. 25can be set to a temporarily fastened state on the basis of an engagement of the engagement projection21with the outer thread310, achieved only by applying (contacting) the engagement portion20to the side surface of the bolt body300without plastically deforming the engagement portion20. Further, the engagement with the outer thread by the engagement projection21is secured from the temporarily fastened state mentioned above by plastically deforming the engagement portion20. In accordance with the employment of the structure mentioned above, since an operator for installation can achieve the temporary fastening by applying the mounting body100to the bolt body300, it is possible to attend only to the plastically deforming work at a time of thereafter plastically deforming the engagement portion20. Therefore, it is possible to securely mount the mounting body100to a desired position in the bolt body.

On the other hand, for example, in the mounting body100(the nut body110) which is formed slightly larger than a diameter of the bolt body300, as shown inFIG. 19, the engagement projection21is not engaged with the bolt body300only by bringing the mounted body100(the nut body110) into contact with the bolt body300. In other words, the engagement projection21is engaged with the outer thread310only by plastically deforming the engagement portion20in which the engagement projection21is provided in a protruding manner.

Further, in the present invention, the mounted subject is the bolt body300, and the engagement projection21of the engagement portion20is engaged with the outer thread310of the bolt body300as mentioned above. Accordingly, it is possible to move the mounting body100with respect to the axial direction of the bolt body300by rotating the bolt body300(or rotating with respect to the bolt body300) in a state in which the engagement projection21in the mounting body100is engaged with the outer thread310of the bolt body300.

It is possible to move (elevate) the mounting body100in the axial direction of the bolt body300by rotating the bolt body300, in a state in which the mounting body100, for example, the wiring material piping material receiving device120, the wiring box130and the like corresponding to the mounted subject, is bonded to the bolt body300such as the suspended bolt which is suspended from the ceiling or the support bolt which is stood by fixing one end to the floor surface. Accordingly, in the case of changing the mounting position of the mounting body100to an optimal position on an entire length of the bolt body300, the mounting body300can be moved by rotating the mounting body100with respect to the bolt body300in a state in which the mounting body100is mounted to the bolt body300, or rotating the bolt body300.

Further, the engagement portion20mentioned above may be constituted by a multi-layer structure. The engagement portion20in accordance with the multi-layer structure has an inner member62and an outer member61, as shown inFIG. 20. Further, the inner member62is structured by a plastic material and the outer member61is structured by a metal which can be plastically deformed. Accordingly, the outer member61presses the inner member62by plastically deforming the outer member61, whereby the inner member62is pressed between the outer member61and the outer thread310of the bolt body300.

Since the inner member62is structured by the plastic material, the inner member62is pressed to the outer thread310of the bolt body300, thereby eating into the outer thread310of the bolt body300. As in the inner member62eats into the outer surface of the bolt body300, the surface in the inner member62, which is brought into contact with the outer thread310of the bold body300, is deformed along the outer thread310of the bolt body300. Accordingly, the engagement projection21is formed on the surface in the inner member62which is brought into contact with the outer thread310of the bolt body300, and the engagement projection21is engaged with the outer thread310of the bolt body300. Accordingly, it is possible to control axial movement with respect to the bolt body300, and it is possible to mount the mounting body100provided with the mounting portion10without moving in the axial direction with respect to the bolt body300.

Next, a description is given of the adjacent portions30. The adjacent portions30are provided in the leading end side of the engagement portion20mentioned above, and correspond to the portions which are relatively close to each other by plastically deforming the engagement portion20.

Further, the adjacent portion30makes mounting easy by being gripped as a grip piece at a time of plastically deforming the engagement portion20. In order to plastically deform the engagement portion20, the pinching operation by the pinching tool P can be easily and securely achieved by gripping the adjacent portion30with the pinching tool P, such as a pincher or the like, as shown inFIGS. 25 and 26.

As a specific aspect of adjacent portion30, it is contemplated to employ a pair of adjacent portions30or a piece of adjacent portion30.

First, a pair of adjacent portions30are structured such that a pair of engagement portions20of the mounting portion10are provided so as to relatively stand face to face, and a pair of adjacent portions30are formed by providing an adjacent portion30at each of the leading end sides of the engagement portions20. Further, the engagement portion20is plastically deformed by moving forward the bolt body to the opening portion70between the adjacent portions30and thereafter moving the adjacent portions30close to each other.

Next, a piece of adjacent portions30is formed by folding the leading end of the engagement portion20to an outer side. In this case, the engagement portion20is formed in an approximately U-shaped cross section extending from a base end of the mounting portion10in the mounting body100. Further, in order to move the adjacent portion30formed in the leading end of the engagement portion20close to a portion near the base end of the engagement portion20in an approximately close contact state, the engagement portion20is plastically deformed after moving forward the bolt body into an inner side of the engagement portion20which has the U-shaped cross section from the opening portion70.

Further, in order to engage projection21with the outer thread310of the bolt body300, the engagement portion20may be plastically deformed until the adjacent portions30provided in the leading end side of the engagement20are in approximately close contact with each other. The engagement projection21provided in a protruding manner in the engagement portion20is engaged with the outer thread310of the bolt body300by clamping the adjacent portions30by means of the pinching tool P, such as a pincher or the like, until the adjacent portions30are relatively in an approximate contact state.

Accordingly, the adjacent portions30are relatively in the approximate close contact state by finishing the engagement with the outer thread310of the bolt body300by means of the engagement projection21. Therefore, the opening portion70(refer toFIG. 25) between the engagement portions20standing face to face is covered and closed by the adjacent portions30in the approximate close contact state. Accordingly, the bolt body300engaging the engagement portion20can be prevented from coming off from the opening portion70, and it is by extension possible to securely mount the mounting body100to the bolt body300.

Further, in the case in which the engagement is finished by positioning the adjacent portions30in the approximate close contact state with each other, as mentioned above, a target for finishing the engagement is set, so that it is possible to necessarily and sufficiently deform the engagement portion20plastically. Accordingly, it is possible to prevent the bolt body300from coming off from the mounting portion10.

On the other hand, the mounting body100in accordance with the present invention may be structured such that the mounting body100is provided with a holding portion50for holding a secondary mounting body200. The mounting body is mounted to the bolt body300in a state in which the holding portion50holds the secondary mounting body200, whereby the secondary mounting body200is mounted to the bolt body300. The secondary mounting body200is structured such as to be placed in the bolt body300and be provided with no mounting portion10. Specifically, as shown inFIG. 33or36, it is contemplated that a wiring material and piping material receiving tool or a wiring material and piping box may be provided with no mounting portion10. Further, the secondary mounting body is not particularly limited to these, and widely include a structure which is fixed by the mounting body100in accordance with the present invention, such as a saddle for fixing the wiring material and the piping material. In the example of the saddle mentioned above, the wiring material and the piping material fixed by the saddle are not included in the secondary mounting body200mentioned above. Thus, only a structure which is directly fixed by the mounting body in accordance with the present invention corresponds to the secondary mounting body200.

In order to mount the secondary mounting body200to the bolt body300in accordance with the mounted subject, the secondary mounting body200can be mounted to the bolt body300by mounting to the bolt body300while keeping the state in which the secondary mounting body200is held by the holding portion50provided in the mounting body100.

The holding portion50may employ any methods or structures. Specifically, for example, as shown inFIG. 3, it is contemplated that a structure, in which the holding portion50is constituted by a flat-shaped contact surface, is formed between a pair of engagement portions20standing face to face. The secondary mounting body200is clamped between the holding portion50and the bolt body300, and the secondary mounting body200is mounted to the bolt body300. In order to clamp the secondary mounting body200between the holding portion50and the bolt body300, for example, it is contemplated that a pair of through holes are pierced in the secondary mounting body200, as shown inFIGS. 33or36. Further, the engagement portion20of the mounting body100provided with the holding portion50is inserted into a pair of through holes. The engagement portion20is applied to the outer surface of the bolt body300from the side portion, and the adjacent portions30are gripped and clamped by the pinching tool P so as to be plastically deformed, as shown inFIGS. 31 and 32. At this time, since the portion between the pair of through holes in the secondary mounting portion200is clamped between the holding portion50and the bolt body300, the secondary mounting body200can be mounted to the bolt body300. In this case, the adjacent portion30provided in the leading end of the engagement portion20may be provided so as to be inclined in the leading end direction of the engagement portion so as to be more easily clamped by the pinching tool P, as shown inFIG. 27.

On the other hand, the mounting body100in accordance with the present invention may be provided with a held portion51in which the secondary mounting body200is placed, and may be structured such that the secondary mounting body200can be placed in the held portion51after mounting or before mounting the mounting body100to the bolt body300. Specifically, as shown inFIG. 39, it is contemplated that a plate-shaped mounting body100is formed by punching a predetermined position of a plate-shaped member so as to form the engagement portion20or the adjacent portion30. A threaded hole is formed in the plate-shaped mounting body100. The secondary mounting body200is placed (fixed) by screwing the secondary mounting body200to the threaded hole.

In accordance with the mounting body100provided with the held portion51, by only bringing the engagement portion20into contact with the bolt body300, it is possible to easily place a conventionally provided pedestal to which various materials can be fixed. In this case, the method of fixing the held portion51and the secondary mounting body200is not limited to the screwing mentioned above, and the held portion51and the secondary mounting body200can be fixed (placed) in accordance with all methods, such as a fitting method, a hooking method, an adhering method and the like which have been conventionally proposed.

Further, the mounting body100, in accordance with the present invention, may be structured such that the mounting portion10is provided with a deviation preventing portion40or the like. The deviation preventing portion40or the like is structured such as to maintain a state in which the engagement portion20, mentioned above, is plastically deformed along the outer surface of the bolt body300. It is possible to prevent the adjacent portion30, which are relatively moved close to each other by plastically deforming the engagement portion20, from being again deviated from each other. It is also possible, by extension, to maintain a state in which the engagement projection21, provided in a protruding manner on the engagement portion20, is engaged with the outer thread310of the bolt body300(hereinafter, referred to as a “deviation preventing effect (opening stop)”).

The deviation preventing portion40or the like comprises the deviation preventing portion40and a deviation preventing member41as already mentioned. A description is given below of each of them.

First, the deviation preventing portion40is integrally structured with the mounting portion10in the mounting body100, and achieves the deviation preventing effect (opening stop). In other words, it is possible to finish the plastic deformation of the engagement portion to lock same by the deviation preventing portion, on the basis of one clamping work by integrally structuring the deviation preventing portion40with the mounting portion10. In particular, as shown inFIG. 4, when a pair of adjacent portions30are provided in the leading end of the engagement portion20, it is contemplated that a hook-shaped member is integrally provided only in one adjacent portion30of a pair of adjacent portions30, and another adjacent portion30is locked with the hook-shaped member provided in one adjacent portion30(refer toFIG. 5). Accordingly, in the case of mounting to the bolt body300by the mounting portion10provided with the hook-shaped member, it is possible to prevent the adjacent portions30from being deviated from each other by locking one of the adjacent portions30with the hook-shaped member while relatively moving the adjacent portion30provided in the leading end of the engagement portion20in order to plastically deform the engagement portion20along the outer surface of the bolt body300.

On the other hand, the deviation preventing member41is structured as an independent member from the mounting portion10, and achieves the deviation preventing effect (opening stop) mentioned above. Specifically, as shown inFIGS. 7 to 16, it is contemplated that an independent member from the mounting portion10is structured such as to be locked with the outer end of the engagement portion20or the adjacent portion30. When the opening stop is achieved by the deviation preventing member41, first, by clamping the adjacent portions30with the pinching tool P, such as a pincher or the like, the engagement portion20is plastically deformed and the adjacent portions30are relatively close to each other. Further, in order to prevent the adjacent portions30moving close to each other from being again deviated, the deviation preventing member41locks so as to cover the plastically deformed outer end of the engagement portion20or the relatively moving, close adjacent portions30.

In this case, the deviation preventing member41may be structured, as shown inFIG. 11or15, such that an opening, open in one side, is formed. It is possible to move forward the bolt body300toward the inner portion of the deviation preventing member41from the opening. After moving forward the bolt body300to the inner portion of the deviation preventing member41, the deviation preventing member41clamps the engagement portion or the adjacent portions in the mounting body100. It is possible to easily and securely carry out the opening stop by employing the structure mentioned above.

In accordance with the structure mentioned above, it is possible to prevent the adjacent portions30, which are once moved close to each other, from being again expanded on the basis of the provision of the deviation preventing portion40or the like in the mounting portion10. It is, by extension, possible to completely maintain the mounting state to the bolt body300by the mounting portion10(or the engagement with the outer thread310of the bolt body300by the engagement projection21).

Next, a description is given of a manufacturing process of the mounting portion10of the mounting body100in accordance with the present invention.

The mounting portion10in the present invention may be structured, as shown inFIGS. 22 to 24, by applying a press mold to a steel plate. It is contemplated that the mounting portion10, having the approximately U-shaped cross section, is formed by arranging the steel plate on a depressed metal mold and pressing the steel plate by a punch from above. In this case, when the engagement projection21in the engagement portion20is constituted by a groove22having a fixed pitch (that is, a spirally inscribed surface), it is considered to be preferable to structure the spirally inscribed surface by forming a plurality of grooves22having a fixed pitch in the steel plate prior to press molding. It is preferably to form the groove22having a fixed pitch (that is, the spirally inscribed surface) as shown inFIG. 21by applying a byte blade to the steel plate and moving the byte blade (or the steel plate) in one direction.

On the other hand, the structure may be made such that the groove22(the spirally inscribed surface) may be formed at the same time of applying the press mold to the steel plate, despite previously forming the engagement projection as mentioned above. Thus, it is possible to form a threaded groove-shaped engagement projection21(the groove22) at a position corresponding to the inner side of the engagement portion by pressing the steel plate into the metal mold as shown inFIGS. 22 to 24by means of a punch provided with a spirally inscribed blade in a leading end.

Next, a description is given of the nut body110. The nut body110is a nut body110which is screwed from a side surface of the bolt body300, and has an engagement portion20and the adjacent portions30. In the present invention, the nut body110is structured such that the mounting portion10in the mounting body100is constructed as an independent member and is mounted to the outer surface of the bolt body300, as the nut body110.

The nut body110can be mounted to the bolt body by applying same to an intermediate portion of the bolt body, in which both ends are already fixed and closed, from a side portion so as to plastically deform, as shown inFIG. 28, whereby it is possible to attach the secondary mounting body, such as the receiving device for the wiring material and the piping material.

As each of the constituting elements in the nut body110is the same as that in the mounting body100mentioned above, a description thereof is omitted.

FIGS. 1 to 20show the nut body110. It is possible to structure a receiving device120, a box130or the like, corresponding to the mounting body provided with the deviation preventing member41, the double-structure engagement portion20or the like, by integrally structuring the nut body110as the mounting portion10in the mounting body100, such as the receiving device120or the like.

BEST MODE FOR CARRYING OUT THE INVENTION

FIGS. 1 and 2show a mounting body100in accordance with embodiment 1. The mounting body100of the present embodiment is structured as a nut body110, and the nut body110has a plastically deformable engagement portion20, a pair of adjacent portions30provided in a leading end side of the engagement portion20, and an opening portion70moving forward a bolt body300into the engagement portion20, as shown inFIG. 1. The engagement portion20is provided in a protruding manner with an engagement projection21engaging with an outer thread310of the bolt body300in accordance with a mounted subject.

In order to mount the nut body110of the present embodiment to the bolt body300, the bolt body300is first moved forward into the engagement portion20from the opening portion70. The engagement portion20is arranged by application to an outer surface of the bolt body300from a side portion. Next, as shown inFIGS. 25 and 26, a pair of adjacent portions30provided in a leading end of the engagement portion20are plastically deformed by being clamped by a pinching tool P, such as a pincher or the like, and the engagement projection21, provided in a protruding manner in the engagement portion20, is engaged with the outer thread310of the bolt body300. At this time, since a pair of adjacent portions30, mentioned above, are in approximately close contact, as shown inFIG. 26, the opening portion70is covered and closed. Accordingly, the nut body110of the present embodiment can be securely mounted without falling off from the bolt body300.

Further, in accordance with the nut body on the basis of the present embodiment, as shown inFIG. 28, it is possible to mount the nut body to the bolt body when both ends are fixed and in a closed state by applying the nut body from a side portion of the bolt body and plastically deforming the nut body.

The cross sectional shape of the nut body110of the present embodiment is not limited to an approximately U-shaped cross section, and may employ a cross sectional shape in accordance with a rectangular shape, as shown inFIG. 3.

FIGS. 4 and 5show a mounting body100of embodiment 2. The mounting body100in the present embodiment is structured as a nut body110. The nut body110has an engagement portion20, an opening portion70, adjacent portions30, and a deviation preventing portion40preventing the adjacent portions30from being deviated. Since the engagement portion20, the adjacent portions30and the opening portion70in the constituting elements are already described with respect to embodiment 1, a description thereof is omitted by attaching the same reference numerals to the drawings.

The deviation preventing portion40is integrally formed with the nut body110, and prevents the adjacent portions30provided in the leading end of the mounting portion10from being deviated (expanded) from each other (hereinafter referred to as a “deviation preventing effect”). The adjacent portions30are deviated from each other, thereby preventing mounting to the bolt body300by the nut body110from being cancelled.

In the present embodiment, when a pair of adjacent portions30are provided in the leading end of the engagement portion20, a hook-shaped member is integrally provided in only one adjacent portion30in a pair of adjacent portions30, and another adjacent portion30is locked to the hook-shaped member provided in the one adjacent portion30. In the case of mounting the mounting portion10provided with the hook-shaped member to the bolt body300, it is possible to prevent the adjacent portions30from being deviated from each other by locking one of the adjacent portions30to the hook-shaped member, while at the same time relatively moving the adjacent portions30provided in the leading end of the engagement portion20toward each other in order to plastically deform the engagement portion20along the outer surface of the bolt body300.

The mounting body100in the present embodiment is structured such that the deviation preventing effect is generated by the deviation preventing portion40integrally provided with the nut body110. However, the deviation preventing portion40is not limited to a structure which is integrally formed with respect to the nut body100. As shown inFIG. 6, the deviation preventing portion may be structured as a deviation preventing member41which is constructed as an independent member from the nut body110, thereby generating the deviation preventing effect mentioned above. As a specific aspect of the deviation preventing member41, the structure shown inFIGS. 7 to 16is considered. A description will be given below of the specific aspect.

First, the nut body110shown inFIG. 6is structured such that a deviation preventing member41, shown inFIG. 7, is put on the nut body110in embodiment 1, and the deviation preventing effect is generated by the deviation preventing member41. The deviation preventing member41shown inFIG. 7is structured such that a protruding piece is stood up by applying a press mold to a plate-shaped member so as to extrude a predetermined position of the plate. Two projections are provided so as to stand face to face. The deviation preventing effect is generate by pinching the adjacent portions30in a relatively close contact state by two projections.

Next, a description is given of a nut body110as shown inFIG. 10. The nut body110shown inFIG. 10is structured such that the deviation preventing effect is generated by arranging the nut body110, shown inFIG. 8, near a bolt body300in accordance with a mounted subject, thereafter plastically deforming the engagement portion20, as shown inFIG. 9, and thereafter putting a deviation member41, shown inFIG. 11, thereon. At this time, the deviation preventing portion40does not pinch a pair of adjacent portions30which are relatively close to each other, but generates the deviation preventing effect by locking the outer end of the engagement portion20by a depression formed in the deviation preventing member41.

Further, a description is given a nut body110as shown inFIG. 14. The nut body110shown inFIG. 14is structured such that the deviation preventing effect is generated by arranging the nut body110, shown inFIG. 12, near the bolt body300in accordance with the mounted subject, thereafter plastically deforming the engagement portion20, as shown inFIG. 13, and putting the deviation preventing member41, shown inFIG. 15, thereon. In this case, the nut body110is structured, as shown inFIGS. 12 to 13, such that one end is formed in a comb teeth-shaped concavity and convexity. On the other hand, a plurality of hole portions are pierced in the deviation preventing member41so as to move forward the comb teeth-shaped concavity and convexity in the nut body110. It is possible to generate the deviation preventing effect mentioned above by engaging a plurality of hole portions and the comb teeth-shaped concavity and convexity with each other.

Further, a description is given of a nut body110as shown inFIG. 16. The nut body110shown inFIG. 16is a nut body110provided with a deviation preventing member41. A slit is formed in the deviation preventing member41in a state in which one end is connected. A notch is formed in an end portion of each of a pair of adjacent portions30in the nut body110. The adjacent portions30are relatively moved close to each other by applying the nut body110to the bolt body300from a side portion thereof and thereafter plastically deforming the engagement portion20as shown inFIGS. 25 and 26. A pair of adjacent portions30, mentioned above, move forward into the slit of the deviation preventing member41by pressing the deviation preventing member41against the notch and mentioned above, whereby the pair of adjacent portions30are pinched by the deviation preventing member41.

At this time, the end portion of the deviation preventing member41enters into the notch of the adjacent portions30. Further, a pair of pawls are formed in the end portion of the deviation preventing member41, and the pawls are engaged with the adjacent portions30. Accordingly, it is possible to prevent the deviation preventing member41from falling off from the nut body110on the basis of a lock by these two points.

In this case, it is necessary to insert the deviation preventing member41shown inFIG. 7from the end portion of the bolt body300to which the mounting body100(the nut body110) is mounted, while mounting the deviation preventing member41to the adjacent portions30of the mounting portion100(the nut body110). However, since the deviation preventing member41shown inFIGS. 11,15and16is released on one side, it is possible to arrange all from a side portion of the bolt body300.

FIG. 17shows a mounting body100in accordance with embodiment 3. The mounting body100of the present embodiment is structured as a nut body110. The nut body110has an engagement portion20, adjacent portions30and an opening portion70. Since the adjacent portions30and the opening portion70in the constituting elements are already described with respect to embodiment 1, a description thereof is omitted by attaching the same reference numerals to the drawings.

The nut body110of the present embodiment is provided with an engagement portion20in accordance with a long size, and is structured such that a pair of adjacent portions30in accordance with a short size are provided in both ends of the engagement portion20so as to stand face to face.

Since the engagement projection21(the groove22) is provided in a protruding manner on an inner side of the engagement portion20all along an entire length, the engagement projection21(the groove22) is engaged with a lot of outer threads in the bolt body, so that it is possible to more securely prevent a displacement which may be generated in an axial direction of the bolt body.

Further, since the adjacent portions30provided in the leading end of the engagement portion20are formed short, it is possible to easily clamp with a tool to plastically deform the engagement portion20in accordance with the long size mentioned above.

The nut body110of the present embodiment may be structured, as described in embodiment 2 mentioned above, such that the deviation portion40or the like is provided so as to generate the deviation preventing effect.

FIG. 18shows a mounting body100in accordance with embodiment 4. The mounting body100in the present embodiment is structured as a nut body110. The nut body110has an engagement portion20, an opening portion70, adjacent portions30, and a deviation preventing member41preventing the adjacent portions30from being deviated from each other. Since the engagement portion20, the opening portion70(not shown), the adjacent portions30and the deviation preventing member41in the constituting elements are already described with respect to embodiments 1 and 2, a description thereof will be omitted by attaching the same reference numerals to the drawings.

The nut body110of the present embodiment is provided with the engagement portion20in accordance with the long size, and is structured such that a pair of adjacent portions30are provided in an intermediate portion of the engagement portion20so as to stand face to face with each other. Since the engagement projection21(the groove22) is provided in a protruding manner on the inner side of the engagement portion20all along the entire length, the engagement projection21(the groove22) is engaged with a lot of outer threads in the bolt body, so that it is possible to more securely prevent a displacement which may be generated in the axial direction of the bolt body.

Further, in the nut body110of the present embodiment, since the adjacent portion30is provided only in one position, in a center of the engagement portion20in a longitudinal direction, it is possible to plastically deform the engagement portion20all along an entire length by clamping the one adjacent portion with the pinching tool P. Further, even in the event that the engagement portion20is operated so as to return to a shape before being plastically deformed (that is, such that the adjacent portion30is expanded), a pair of adjacent portions30that are relatively moved close to each other are pinched by the deviation preventing member41, so that it is possible to securely prevent a pair of adjacent portions30from being again expanded.

The engagement projection21may not be provided in a protruding manner in an inner side of a band-shaped portion (narrow portion) in accordance with the engagement portion20in which a pair of adjacent portions30are formed (refer toFIG. 19). In other words, if an engagement projection21is provided in a protruding manner in an arc-shaped portion (an upper half circle portion) shown inFIG. 25, it is possible to mount the nut body100to the bolt body300by plastically deforming the engagement portion20in accordance with the band-shaped portion so as to clamp the engagement portion20, even when the engagement projection21is not provided in a protruding manner in the other portions.

FIG. 19shows a mounting body100of embodiment 5. The mounting body100in accordance with the present embodiment is structured as a nut body110. The nut body110has an engagement portion20, an opening portion70, adjacent portions30and a slit41. Since the engagement portion20, the opening portion70(not shown) and the adjacent portions30in the constituting elements are already described with respect to embodiments 1 and 2, the description thereof is omitted by attaching the same reference numerals to the drawings.

The nut body110of the present embodiment is structured such that a pair of adjacent portions30are provided in a protruding manner in the leading end portion of the engagement portion20so as to stand face to face with each other, and an engagement projection21(a groove22) is provided in a protruding manner on an inner side of the engagement portion20all along an entire length thereof. Accordingly, since the engagement projection21(the groove22) is engaged with a lot of outer threads in the bolt body, it is possible to prevent a displacement which may be generated in the axial direction of the bolt body.

Further, a slit is formed in a back surface of the nut body110(that is, an intermediate portion of the engagement portions20which stand face to face with each other). Accordingly, since it is possible to substantially shorten a dimension in a longitudinal direction in the plastically deformed engagement portion20, it is possible to plastically deform the engagement portion20in accordance with the long size even by a small amount of work. This is particularly effective in the case that the engagement portion20is formed by the long size.

FIG. 3shows a mounting body100in accordance with embodiment 6. The mounting body100in the present embodiment is structured as a fixing device for attaching the secondary mounting body200to the bolt body. The fixing device has an engagement portion20, an opening portion70, adjacent portion30, and a holding portion50holding the secondary mounting body200. Since the engagement portion20, the opening portion70and the adjacent portions30in the constituting elements are already described in with respect to embodiment 1, a description thereof is omitted by attaching the same reference numerals to the drawings.

The holding portion50holds the secondary mounting body200, and is structured such that the secondary mounting body200can be mounted to the bolt body300by mounting the mounting body100(the fixing device) of the present embodiment to the bolt body300in a state in which the secondary mounting body200is held by the holding portion50.

In the present embodiment, as shown inFIG. 3, the portion between the pair of engagement portions20, provided so as to stand face to face with each other, is set as the holding portion50, the secondary mounting body200is clamped between the holding portion50and the bolt body300, and the secondary mounting body200is mounted to the bolt body300. In this case, in the secondary mounting body200mentioned above, after piercing a pair of through holes in the secondary mounting body200, inserting the engagement portion20of the mounting body100(the fixing device) provided with the holding portion50into a pair of through holes, and applying the engagement portion20to the outer surface of the bolt body300from the side portion, as shown inFIG. 33(the wiring material and piping material receiving device120) orFIG. 36(the wiring material and piping material box130), the plastic deformation is applied as shown inFIGS. 31 and 32. At this time, since a portion between a pair of through holes in the secondary mounting body200is clamped between the holding portion50and the bolt body300, it is possible to mount the secondary mounting body200to the bolt body300.

In this case, the mounting body100(the fixing device) of the present embodiment may be structured, as described in embodiments 1 and 2 mentioned above, such that a spirally inscribed surface shaped engagement projection21is provided in a protruding manner by arranging the grooves22in parallel, or the deviation preventing effect is generated by arranging the deviation preventing portion40or the like.

FIG. 20shows a mounting body100in accordance with embodiment 7. The mounting body100of the present embodiment is structured as a nut body110. The nut body110has an engagement portion20, adjacent portions30and an opening portion70.

The outer member61is formed by a plastically deformable metal. The inner member62is formed by a plastic material represented by a synthetic resin, such as a plastic or the like. The outer member61presses the inner member62by plastically deforming the metal material structuring the outer member61. The engagement projection21is formed by deformation of the plastic material structuring the inner member62along the outer thread310of the bolt body300, and the engagement projection21is engaged with the outer thread310of the bolt body300.

The inner member62eats into the outer surface of the bolt body300, whereby a surface in the inner member62, which is brought into contact with the outer thread310of the bolt body300, is deformed along the outer thread310of the bolt body300. Accordingly, the engagement projection21is formed in the surface of the inner member62which is brought into contact with the outer thread310of the bolt body300, and the engagement projection21is engaged with the outer thread310of the bolt body300.

Further, since the inner member62can be optionally deformed along the outer thread310, the inner member62can be engaged with the outer thread310at whatever pitch is formed in the outer thread of the bolt body300corresponding to the engaged subject. Accordingly, the mounting body100of the present embodiment can be mounted to the bolt body300which is formed with every outer diameter.

In this case, the nut body110in accordance with the present embodiment may be constructed as a structure in which the deviation preventing effect is generated by arranging the deviation preventing portion40or the like, as is described in embodiment 6 mentioned above.
