  It is an object of the present invention to prevent the locking from being easily released by a load acting on one of the two members in a state where the two members are connected to each other by a locking structure.

The invention according to claim 1 for solving the above-mentioned problems is a base member having an attachment portion for a structure such as a bolt shaft and a wall body, and a holding portion for holding a held body such as a wiring / piping material and a bolt shaft. A holding member comprising a holding member having
One or both of the base member and the holding member have a part or part of the circular ring that is cut out, so that the base member and the holding member have a circumferential length in the ring direction that is longer than the missing part, and the outer side has The incomplete annular wall portion having the two locking portions is formed, and the incomplete annular wall portion is disposed at the lacking portion so as to be elastically deformable in the inward and outward directions of the annular ring. A first connecting portion including an elastic wall portion formed with a locking portion,
On the other of the base member and the holding member, the incomplete annular wall portion and the elastic wall portion are formed in the arrangement space portion capable of being inserted and arranged, and a part along the annular direction in the arrangement space portion, A second connecting portion including a locked portion that can be locked with respect to each of the first and second locking portions of the elastic wall portion and the incomplete annular wall portion,
Each of the first and second connecting portions has a center of the ring as a center of rotation by a locking structure of one of the first and second locking portions and the locked portion. It is characterized in that they are connected so as to be relatively rotatable while maintaining the locked state.

  According to the invention of claim 1, the positions of the first locking portion formed on the elastic wall portion of the first connecting portion and the locked portion formed on the second connecting portion in the annular direction are matched. In this state, when the first and second connecting portions are relatively pressed, the elastic wall portion is elastically deformed inward with respect to the ring, and then restores to its original shape. The first locking portion on the outer side of the portion and the locked portion of the second connecting portion are locked to each other, and the incomplete annular wall portion of the first connecting portion is provided in the arrangement space portion of the second connecting portion. And the elastic wall portion is inserted and arranged.

  In this state, the first and second connecting portions, that is, the base member and the holding member are connected to each other by the locking structure. Since the elastic wall portion is arranged in the missing portion of the incomplete annular wall portion of the incomplete annular shape, and the complete annular wall portion is formed by combining both wall portions, it is held with the base member in the above connected state. It is possible to relatively rotate the member, and by the relative rotation, the locked portion formed in the second connecting portion is made to correspond to the first locking portion of the elastic wall portion of the first connecting portion. Is unlocked and is locked to the second locking portion of the incomplete annular wall portion disposed adjacent to the elastic wall portion, so that the connection state between the base member and the holding member is maintained as it is. ing. The locked portion of the second connecting portion is locked to the second locking portion of the incomplete annular wall portion of the first connecting portion that is not elastically deformed, and thus the second engaging portions that are locked to each other. Even if a load acts on the mutual locking portion of the stopper and the locked portion, the imperfect annular wall portion is not easily deformed, so that the locking of the mutual locking portion is not easily released. Therefore, the held object can be safely held for a long period of time.

  According to the invention of claim 2, in the invention of claim 1, the elastic deformation direction of the elastic wall portion is different from a direction of a load exerted on the holding portion by the held body held by the holding portion. It has a feature.

Since it is different from the elastic deformation direction, the elastic wall portion is not elastically deformed by the load acting on the holding portion, that is, the locked state does not change in the releasing direction. Therefore, even if the base member and the holding member are still connected to each other by the locking structure, the locking is not easily released, and the held object can be stably held for a long period of time.

  According to a third aspect of the invention, in the first or second aspect of the invention, the incomplete annular wall portion is inside the incomplete annular wall portion in a connected state of the first and second connecting portions. It is characterized in that a deformation preventing portion for preventing the deformation of is provided.

  According to the invention of claim 3, the presence of the deformation preventing portion can prevent the incomplete annular wall portion that is not elastically deformed from being deformed. Therefore, the second locking of the incomplete annular wall portion forming the first connecting portion is possible. It is possible to maintain the locked state between the portion and the locked portion that forms the second connecting portion, and release the locking while the held body is held by the holding portion of the holding member. Safety can be improved because it can be reliably prevented.

Is a swing-off bolt body arranged to intersect with the suspension bolt, and the elastic wall portions are formed in a pair so as to face each other along the axial direction of another bolt body held by the holding portion. Is characterized by.

  According to the invention of claim 4, the swing stop bolts are arranged in an inclined manner, and the elastic wall portion forming the first connecting portion is arranged along the axial direction of the swing stop bolts. On the other hand, since the load of the held body held by the holding member is along the vertical direction, the mutual locking portion of the first locking portion of the elastic wall portion and the locked portion of the second connecting portion. In addition, the load does not act directly. Therefore, the locking between the second locking portion and the locked portion in the mutual locking portion is less likely to be released.

  A fifth aspect of the present invention is characterized in that, in the fourth aspect, the base member and the holding member have an angle display portion that indicates an intersection angle between the suspension bolt and the swing stop bolt.

  According to the invention of claim 5, the first locking portion of the elastic wall portion of the first connecting portion and the locked portion of the second connecting portion are locked to each other, whereby the base member and the holding member are formed. Is a reference position, and the holding portion of the holding member holds the tilting bolts, so that the base member and the holding member have the tilting bolts with respect to the reference position. It is arranged so as to be relatively rotated by an inclination angle. The base member and the holding member have an angle display portion showing an intersecting angle of the suspension bolt and the swing bolt, and the base member and the holding member are the same angle as the inclination angle of the swing bolt. Since the relative rotation angle is displayed on the angle display unit, the tilt angle of the swing stop bolt can be visually recognized without using an angle measuring device.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

First, the holder A ₁ of Example 1 of the present invention will be described with reference to FIGS. 1 to 5. As shown in FIGS. 10 and 11-B (d), the pipe body P that is the held body is hung on the ceiling wall W by the hanging bolt B ₁ , and the holding body A ₁ is the hanging bolt B ₁ described above. And a base member V ₁ which is used to connect the suspension bolt B ₁ with a vibration-prevention bolt B ₂ which is a vibration-prevention member for preventing the vibration of the suspension bolt B ₁ , and which is fixed to the suspension bolt B ₁ . The base member V ₁ and the holding member S ₁ that is integrally connected to the base member V ₁ by a locking structure and holds the swing-off bolt B ₂ . Here, the holding member S ₁ is described as holding the swing-fastening bolt B ₂ , but from the aspect of the size and weight of the two, “the holding member S ₁ is held with respect to the swing-fastening bolt B ₂ ”. Although it can be expressed as follows, it is expressed as described above from the viewpoint of the original function of the holding body A ₁ of the present invention. Both the base member V ₁ and the holding member S ₁ are formed by injection molding of resin.

The base member V ₁ and the holding member S ₁ are both the same size and have a regular octagonal shape in a front view, and the two are integrally connected in a rotatable state by a locking structure. The base member V ₁ has a regular octagonal disc-shaped main body portion 1, and the incomplete annular wall portion 12 and the elastic wall portion 13 of the holding member S ₁ are accommodated and arranged on the inner surface of the main body portion 1. A non-penetrating annular arrangement space portion 2 that can be formed is formed, and a circular ring shape that is concentric with the space portion 2 for preventing deformation of the incomplete annular wall portion 12 is formed inside the space portion 2. The deformation preventing portion 3 is formed. The end surface 3a of the circular ring-shaped deformation preventing portion 3 and the inner surface of the main body portion 1 are arranged substantially on the same plane. A pair of locked claws 5 are formed on the opposing portions of the inner peripheral surface 2a of the arrangement space 2, and a holding member S ₁ is formed on the portion of the main body 1 corresponding to the pair of locked claws 5. A through hole 7 for partially inserting the first locking claw 14 is formed in the radial direction of the circular ring-shaped deformation preventing portion 3. The circumference of each locked claw 5 along the annular direction is about (1/10) of the annular circumference. When the base member V ₁ and the holding member S ₁ are pressed against each other and connected by the locking structure, the inclined elastic contact surfaces 14a of the first locking claws 14 of the pair of locked claws 5 are elastically contacted with each other. The portion is an inclined elastic contact surface 5a [see FIGS. 3 and 5 (a)]. As shown in FIGS. 3 and 5, the locked claws 5 and the through holes 7 are formed in the front half and the rear half along the depth direction of the arrangement space 2. ing. The arrangement space portion 2 and the pair of locked claws 5 constitute a second connecting portion C _{2 which} is connected to a later-described first connecting portion C ₁ of the holding member S ₁ . In the arrangement space portion 2 of the base member V ₁ , the incomplete annular wall portion 12 and the elastic wall portion 13 of the holding member S ₁ are accommodated and arranged, and both members V ₁ and S ₁ are integrally connected, the holding member S ₁ of incomplete annular wall portion 12 and the elastic wall portion 13 there is also the guide space when rotating, capable of changing the relative positional relationship between the base member V ₁ and the holding member S ₁ Because of the configuration, the arrangement space portion 2 can also be referred to as a “rotation guide space portion”.

_On the outer surface of the base member V ₁ , a pair of attachment pieces 8 fixed in a detachable manner to the suspension bolt B ₁ are formed. The pair of attachment pieces 8 having a circular cross section are elastically deformable, and the insertion openings 8a are formed in the opposite directions.

On the other hand, the holding member S ₁ has a state in which an incomplete annular wall portion 12 composed of a pair of divided incomplete annular wall portions 12a having the same circumference along the annular direction is arranged to face each other on the inner surface of the main body portion 11. And a pair of elastic wall portions 13 are formed so as to be opposed to each other between the incompletely divided annular wall portions 12a. In other words, the incomplete annular wall portion 12 is formed by omitting two opposing portions of the annular ring. On the outside of the pair of elastic walls 13 and a pair of split incomplete annular wall portion 12a, each of the first and second locking claws 14 each of the locking claw 5 of the base member V ₁ respectively is locked , 15 are formed over the entire circumference in the annular direction. The first locking claw 14 presses the base member V ₁ and the holding member S ₁ against each other to engage the first locking claw 14 of the holding member S ₁ with the locked claw 5 of the base member V _1. An inclined elastic contact surface 14a is formed to elastically contact the inclined elastic contact surface 5a of the locked claw 5 when stopped. However, the second locking claw 15 and the locked claw 5 are locked by the base member V ₁ and the holding member S ₁ by the locking structure of the locked claw 5 and the first locking claw 14. After being connected, the members V ₁ and S ₁ are locked relative to each other by rotating them relative to each other, so that the first locking claws 14 are inclined with respect to the second locking claws 15. The surface for the elastic contact surface 14a is formed perpendicularly to the inner surface of the main body 11 (see FIG. 3). A pair of holding pieces 16 having the same structure as the pair of attaching pieces 8 of the base member V ₁ are formed on the outer surface of the main body 1. When the sizes of the members attached to the base member V ₁ and the holding member S ₁ or the members themselves are different, the shapes of the attachment piece 8 and the holding piece 16 are naturally different. Since each elastic wall portion 13 is thinner than the incomplete annular wall portion 12 and has a short circumferential length along the annular direction, the elastic wall portions 13 are orthogonal to the annular direction (annular ring orthogonal direction). When an external force is applied in the radial direction of the circular deformation prevention portion), it is elastically deformed in the direction orthogonal to the ring, but each divided incomplete ring wall portion 12a has a circumferential length along the ring direction. Since the elastic wall portion 13 is much longer than the elastic wall portion 13, it has a structure in which it is not deformed even when an external force in the direction orthogonal to the ring acts. In FIG. 2, reference numeral 17 denotes a partial female screw portion formed on the back surface of the main body 11 of the holding member S ₁ .

Then, as shown in FIG. 1, the pair of locked claws 5 of the base member V _{1 and} the pair of first locking claws 14 formed on each elastic wall portion 13 of the holding member S ₁ are formed into an annular shape. When the base member V ₁ and the holding member S ₁ are pressed against each other in a state where the phases are matched with each other in the direction, the divided incomplete annular wall portions 12a and the elastic wall portions 13 of the holding member S ₁ A portion of which is an annular wall portion which is continuously formed along the annular direction is inserted and arranged outside the annular ring-shaped deformation preventing portion 3 in the arrangement space portion 2 of the base member V ₁ and the holding member S. _After each elastic wall portion 13 of ₁ is elastically deformed inward, and then restored to the original shape, each first locking claw 14 provided on the outside of each elastic wall portion 13 of the holding member S ₁ , The locked claws 5 of the base member V ₁ are locked to each other, and the base member V ₁ and the holding member S ₁ are connected to each other by the first and second connecting portions. They are connected to each other via C ₁ and C ₂ .

Therefore, as shown in FIG. 6A, the first locking claws 14 of the elastic wall portions 13 of the holding member S ₁ and the locked claws 5 of the base member V ₁ are engaged with each other. from sealed connection immediately after state, to thereby relatively rotating the holding member S ₁ and the base member V ₁ [FIG. 6 (b) ~ (d), the base member V ₁ relative to the holding member S ₁ Is shown in a state of being rotated by 15 ° each], and the locked claws 5 of the base member V ₁ are different from the first locking claws 14 of the elastic wall portion 13 of the holding member S ₁ . The locking is released and locked by the second locking claw 15 of the incompletely divided annular wall portion 12a, whereby the base member V ₁ and the holding member S ₁ are relatively rotated, and locking is maintained, yet each first locking claw 14 of the holding member S ₁ of the elastic wall 13, the second engagement claw 15 Togakakari sealed state of division incomplete annular wall 12a , The divided incomplete annular wall section 12a can not be elastically deformed, is maintained the state of the locking, coupling the base member V ₁ and the holding member S ₁ is being released, the two are separated There is no. In addition, in FIG. 6, G indicates a rotation center when the base member V ₁ and the holding member S ₁ relatively rotate in the integrally connected state.

Further, in order to fix the holding body A ₁ in which the base member V ₁ and the holding member S ₁ are integrally connected as described above to the swing-fastening bolt B ₂ , as shown in FIG. With the swing-fastening bolt B ₂ inserted between the pieces 16, the holding body A ₁ is rotated in a predetermined direction with respect to the swing-fastening bolt B ₂ to elastically deform each holding piece 16 and By inserting different portions of the swing stop bolt B ₂ from the insertion openings 16a of the holding pieces 16, each elastically deformed holding piece 16 is restored to its original shape, and is suspended from the pair of attachment pieces 8. The bolt B ₁ is fixed. Note that by partial female thread portion 17 of the holding member S ₁ of a holding member A ₁ is engaged portion threaded into Futome bolts B _2, holding member A ₁ is in the axial direction with respect Futome bolt B ₂ It will not shift. On the other hand, to change the fixed position of the retaining member A ₁ for Futome bolts B _2, with respect to the Futome bolts B ₂ is threadably turning the holder A ₁ in any direction, either direction When the holding body A ₁ is forcibly slid in the axial direction with respect to the swinging bolt B ₂ , the pair of attachment pieces 8 are slightly elastically deformed outward and then restored to the original shape. By doing so, the fixing position for the swing stop bolt B ₂ is changed. Further, in removing the holder A ₁ from the Futome bolts B ₂ are the retaining member A ₁ may only be rotated in the reverse direction to Futome bolt B _2. Note that the inner surface of the attachment piece 8 and the holding pieces 16, two bolts B _1, B ₂ of the screw enters the groove engaged by the latching prong pieces 8b, 16b are formed.

As shown in FIGS. 10 and 11-B (d), the base member V ₁ and the holding member S ₁ have the same size and are formed in a regular octagonal shape in a front view. In order to prevent the suspension bolt B ₁ for suspending the pipe body P from swinging, the swing bolt B ₂ is connected to the suspension bolt B ₁ via the holding body A _1, and a separate protractor or the like is used. This is because the intersection angle (θ) of the _two bolts B ₁ and B ₂ can be visually recognized only by the holding body A ₁ without using the angle measuring tool. As a specific example thereof, as shown in FIGS. 6 and 7, in addition to the configuration in which the base member V ₁ and the holding member S ₁ have the same size and are formed in a regular octagonal shape in a front view, In the center portions of the angle display surfaces 21 and 22 which are the respective regular octagonal central angles of 45 °, the base member V ₁ and the holding member are provided by providing the visible concave portions 23 and 24 having a width of 1/3 of the side width. This is to make the relative rotation angle of the member S ₁ visible in units of 15 °. Here, regarding the plurality of visual recognition recesses 23 and 24, if it is necessary to specify each of them for the sake of explanation, they are displayed as 23a, 23b, 23c, 23d (24a, 24b, 24c, 24d). . Note that, in FIGS. 6 and 7, the cross-hatched portions are the recessed portions 23 and 24 for visual recognition.

Futome bolt B ₂ is a Futome volts for performing steadying the bolt B ₁ hanging from the ceiling wall W are suspended pipe P, when placed at an angle to the hanger bolts B _1, Futome effect It is most effective when the crossing angle of the _two bolts B ₁ and B ₂ is 45 °. For example, the building equipment seismic design / construction guideline (2014) recommends the intersection angle to be (45 ° ± 15 °).

Therefore, as shown in FIG. 7, two bolts B ₁ of which are connected to each other by the holding member A _1, in the state in which B ₂ is not intersect mutually parallel, the base member forming the holding member A ₁ V ₁ and the holding member S ₁ are completely overlapped with each other in a front view to form the same surface where the respective angle display surfaces 21 and 22 are continuous and the same recesses where the respective visual recognition concave portions 23 and 24 are continuous. is doing. In this state, when the swing-fastening bolt B ₂ is rotated by 30 ° with respect to the suspension bolt B ₁ , as shown in FIG. 8A, the holding member S ₁ has the same angle with respect to the base member V ₁ . By rotating, the distal ends of the holding member S ₁ in the width direction of the visual recognition recesses 24b, 24c in the width direction are aligned with the widthwise ends of the visual recognition recesses 23b, 23c of the base member V _1. It can be seen that the anti-swing bolt B ₂ has been rotated 30 ° with respect to the suspension bolt B ₁ . Further, as shown in FIG. 8 (b), when the holding member S ₁ with respect to the base member V ₁ is to 45 ° rotation, the holding member S ₁ is being rotated by the same angle with respect to the base member V ₁ Te, each viewing recess 24b of the holding member S _1, and 24c, each of the viewing recess 23a of the base member V _1, 23b and is by complete matching, the bolt B ₂ vibration with respect to hanger bolts B ₁ 45 ° It can be seen that it has been rotated. In this state, since the outer shapes of the base member V ₁ and the holding member S ₁ are completely matched, it is easier to recognize the intersection angle of 45 °. Further, when the swinging bolt B ₂ is rotated by 60 ° with respect to the suspension bolt B ₁ , the holding member S ₁ is rotated by the same angle with respect to the base member V ₁ as shown in FIG. 8C. Then, the rear ends of the holding members S ₁ in the widthwise direction of the visual recognition recesses 24b, 24c in the width direction are aligned with the widthwise ends of the visual recognition recesses 23a, 23b of the base member V ₁ . It can be visually recognized that the swing-off bolt B ₂ is rotated by 60 ° with respect to the hanging bolt B ₁ .

In actual construction, the work while checking the intersection angle of the _two bolts B ₁ and B ₂ with a protractor or the like is time-consuming and troublesome, but when the holder A _{1 according} to the present invention is used, After that, the intersection angle of the _two bolts B ₁ and B ₂ can be visually recognized, and the _two bolts B ₁ and B ₂ can also be installed by intersecting at the set intersection angle.

The technical idea including the above-described specific example in which the intersection angle (θ) between the _two bolts B ₁ and B ₂ can be visually recognized can be expressed as follows.

A bolt shaft connecting tool in which two bolt shafts intersecting at a predetermined angle are connected to each other at an intersecting portion, and an intersecting angle of the two bolt shafts can be visually recognized.
The bolt shaft connecting device has a pair of connecting members that have respective attaching portions to which the bolt shafts can be attached, and can be connected to each other in a rotatable state via the connecting portions.
The bolt shaft connecting device, wherein each of the connecting devices is provided with an angle display portion for visually observing a relative rotation angle of the connecting device.

Specifically, the “pair of connected concrete bodies” is composed of the base member V ₁ and the holding member S ₁ , and the “connecting portion” is the first and second connecting portions C ₁ and C ₂ . The "attachment portion" is configured by the attachment piece 8 and the holding piece 16, and the "angle display portion" is formed by the base member V ₁ having a regular octagonal front shape and the holding member. The angle display surfaces 21 and 22 and the visual recognition concave portions 23 and 24 formed on the outer peripheral end surfaces of S ₁ are formed.

  The bolt shaft connector according to the above technical idea is not limited to the above configuration. For example, the "connecting tool" may have the configuration described in Patent Document 1 described above as long as the "connecting tool" is rotatable with respect to each other, and the "angle display section" is not a regular octagon but a disk-shaped body section. May be provided with an angle display portion, and its shape is arbitrary.

Then, as shown in FIG. 10, FIG. 11-A, and FIG. 11-B, the hanging bolt B ₁ having the upper end screwed is suspended from the bolt connector K ₁ fixed to the ceiling wall W. The pipe body P is connected to the lower end portion of the suspension bolt B ₁ via a suspension metal fitting 41 in a suspended state, and the swing bolt B ₁ is shaken by the swing bolt B ₂ as follows. Is done in this way. A female screw body (not shown), which is arranged inside the bolt connector K ₁ fixed to the ceiling wall W and to which the upper end portion of the hanging bolt B ₁ is screwed, is arranged in a fixed state. Since the hanging bolt B ₁ having the upper end screwed to the female screw body is long, the hanging bolt B ₁ swings at the lower end. On the other hand, in order to suspend the swing-fastening bolt B ₂ , a spherical female member arranged inside the bolt connector K ₂ fixed to the ceiling wall W at a predetermined distance from the bolt connector K ₁ . Since the screw body 31 (see FIG. 10) is arranged so as to be rotatable in all directions, the swing-fastening bolt B ₂ whose upper end is screwed into the bolt connector K ₂ is large in all directions. Can be shaken. Intervals of the bolt connector K _1, K ₂ are, when coupled with the inclined arrangement with respect to hanger bolts B _1, setting the tilt angle of the Futome bolt B ₂ theta, the length of the Futome bolt B ₂ Is determined in consideration of.

First, as shown in FIG. 11-A (a), by crossing the bolt B ₂ vibration with respect to hanger bolts B ₁ at a predetermined position, determining the intersections expected position D Futome bolts B _2. The intersection angle θ between the _two bolts B ₁ and B ₂ is arbitrarily determined by changing the planned intersection position D. Next, the holding member S ₁ forming the holding body A ₁ is attached to the predetermined crossing position D of the swing stop bolt B ₂ using the pair of holding pieces 16 [FIG. 11-A (b)]. Next, by intersecting the bolt B ₂ vibration with respect to hanger bolts B _1, is arranged a bolt B ₁ hanging between the holding member A ₁ pair of attachment pieces 8 of the base member V ₁ constituting the [Figure 11-B (c)], in this state, the base member V ₁ is rotated in a predetermined direction with respect to the holding member S ₁ forming the holding body A ₁ , and the pair of attachment pieces 8 are used to The base member V ₁ is attached to the hanging bolt B ₁ [FIG. 10 and FIG. 11-B (d)]. Thus, a hanging bolt B _1, the angle between the inclined arranged vibration stopped Futome bolt B ₂ is (theta), is connected via a holding member A _1, the bolt B ₁ hanging by Futome bolts B ₂ Shaking is prevented, and visual recognition recesses 23a, 23b, 23c, 23d (24a, 24b, 24c, 24d) formed on the outer peripheral end surfaces of the base member V ₁ and the holding member S ₁ constituting the holding body A _1. The crossing angle θ between the _two bolts B ₁ and B ₂ can be confirmed by the arrangement position of). The inclination angle θ of the swing stop bolt B ₂ shown in the figure is 45 °.

In this way, since the crossing angle θ can be known by the holding body A ₁ for connecting the _two bolts B ₁ and B ₂ at the crossing portion, the two bolts B ₁ and B ₂ are being installed. Moreover, since it is not necessary to work while applying an angle measuring tool such as a protractor, the installation work can be performed quickly. In addition, when the range of the intersection angle θ of each of the two bolts B ₁ and B ₂ is defined and it is required to submit the construction photograph, the intersection angle can be determined by the angle measuring tool at each of a number of construction sites. it is necessary to photograph the apparent state, according to the holding member a _1, without using the angle measuring instrument, the so intersection angle θ is found by the holding member a ₁ itself, easy shooting operations in a number of construction site Becomes

When the tilting angle θ of the swing stop bolt B ₂ is 45 °, as shown in FIG. 6C, the base member V ₁ and the holding member S ₁ are separated from each other by the first and second members. The connecting portions C ₁ and C ₂ hold the locking structure and are connected so as to be relatively rotatable. Thus, a pair of Hikakaritometsume 5 of the base member V _1, a pair of a state where the first locking claw 14 Togakakari sealed holding member S _1, the base member V ₁ is the holding member S ₁ When it is rotated by 45 °, the locked claws 5 of the base member V ₁ and the first locking claws 14 of the holding member S ₁ are kept in the locked state. The claws 5 are partially locked to the annular second locking claws 15 that are arranged so as to be connected to the first locking claws 14 along the annular direction [FIG. )], The engagement with the first locking claws 14 is released, and the second locking claws 15 are locked. Thus, even if the base member V ₁ and the holding member S ₁ are rotated relative to each other, both members V ₁ and S ₁ are always maintained in the locked state, so that both members are in the middle of rotation. There is no risk of V ₁ and S ₁ being separated. When the inclination angle θ is 30 °, as shown in FIG. 6B, the locked claws 5 of the base member V ₁ are locked by the first and second locking members of the holding member S ₁ . The locked state when the claws 14 and 15 are locked while straddling the claws 14 and 15 and the inclination angle θ is 60 ° is the same as the case of 45 ° described above, as shown in FIG. 6D. .

Here, as shown in FIGS. 6B to 6D, when the locked claw 5 of the base member V ₁ is locked by the second locking claw 15 of the holding member, The incompletely divided annular wall portion 12a in which the two locking claws 15 are formed has a far larger center angle than the center angle of the elastic wall portion 13 whose overall shape is a circular arc, and is in the annular direction. Since a long circumferential length is secured along the elastic wall portion 13 and the elastic wall portion 13 is formed thicker than the elastic wall portion 13, in other words, since it has high deformation resistance rigidity, the anti-slip bolt Even if the weight of B ₂ acts on the portion of the second locking claw 15 as a load, the second locking claw 15 does not easily deform. Therefore, even if the load continues to act on the portion of the second locking claw 15 of the holding member S ₁ for a long time, the second locking claw 15 of the holding member S ₁ and the locked claw 5 of the base member B. Since the engagement with and is not easily released, the held body such as the pipe body P can be safely suspended.

Further, as shown in FIG. 12, even when the two suspension bolts B ₁ that are hung adjacent to each other with a predetermined space between them are stopped by the horizontally installed stop bolts B ₃ , The holder A ₁ can be used. That is, it is only necessary to connect the two suspension bolts B ₁ and the swing-off bolts B ₃ arranged orthogonal to the respective suspension bolts B ₁ by the holding body A ₁ .

The base member V ₁ and the holding member S ₁ of the holding body A ₁ include a pair of second locking claws 15 formed on the incomplete annular wall portion 12 that does not elastically deform of the holding member S _1. The base member V _{1 is connected to} the pair of locked claws 5 with a necessary connecting strength, and there is little risk of separation of the members V ₁ and S ₁ during use. However, as shown in FIG. 13, when the respective members V ₁ and S ₁ and the respective bolts B ₁ and B ₂ are integrally bound by the binding band 32, a total of 4 at the intersections of the respective bolts B ₁ and B _2. since One of members can tie together, at the intersection of each bolt B _1, B _2, with each member V _1, S ₁ is not separated, _1, B ₂ is out bolts B from the member V _1, S ₁ Can also be prevented. In particular, as shown in the drawing, when the bolts B ₁ and B ₂ intersect at 45 °, the visual recognition concave portions 23 and 24 of the respective members V ₁ and S ₁ are aligned, so that the visual recognition concave portions 23 and 24 are formed. By fitting a part of the binding band 32 into the, the binding band 32 can be bound without slipping.

In the first embodiment, the suspension bolt B ₁ and the swing stop bolt B ₂ are used in combination, and it is planned that the suspension bolt B ₁ and the swing stop bolt B ₂ are used in a crossed state. , We do not plan to connect them in parallel. Attached Therefore, parallel and consisting direction (axial direction of the hanger bolts B ₁₎ which, as a facing direction of the pair of elastic wall portion 13 of the holding member S _1, the holding member S ₁ to the hanging bolts B ₁ Then, in the intersecting state of the suspension bolt B ₁ and the swing stop bolt B ₂ , only the first locking claw 14 of the elastic wall portion 13 is not locked with the locked claw 5 of the base member V _1. . If there are three or more locked portions of the base member (elastic wall portions of the holding member), one specific locked portion and the first locking portion of the specific elastic wall portion are locked. However, since the remaining one or more locked portions are locked with the second locking portions formed on the incomplete annular wall portion, the locked state is stabilized.

Further, FIG. 14 shows a holder A ₁ ′ that is a partial modification of the holder A ₁ described above. In this holding body A ₁ ′, the base member V ₁ of the holding body A ₁ is provided with a pair of locked claws 5 and the holding member S ₁ is provided with a pair of first locking claws 14. On the other hand, one of the pair of locked claws 5 and the pair of first locking claws 14 is omitted to make only one each, and the pair of divided incomplete annular wall portions 12a that have been divided. To form an incomplete annular wall portion 12 '. In other words, the incomplete annular wall portion 12 'is formed by omitting only a part of the annular ring. In the holding body A ₁ , the pair of elastically deformable first locking claws 14 are necessary only when the base member V ₁ and the holding member S ₁ are connected, and when the swing bolt B ₂ is used. Since the pair of first locking claws 14 are locked to the first locking claws 14 formed on the incomplete annular wall portion 12 that is not elastically deformable, the first locking claws 14 are Even if only by itself, the connection between the base member V ₁ 'and the holding member S ₁ ' is not released.

Here, when the number of the first locking claws 14 is one as in the above-mentioned holding body A ₁ ′, when a prying force acts on the base member V ₁ ′ and the holding member S ₁ ′, the locking is performed. Although there is a risk that the structural part will be unlocked and come off, it is possible to prevent twisting of both members V ₁ ′ and S ₁ ′ by increasing the depth of the arrangement space part 2 of the base member V ₁ ′. , Stable connection is possible. As in the case of the holding body A ₁ , by providing the locking structure portions at two locations or at a plurality of locations exceeding this, both members V and S are less likely to be twisted, and the depth of entry into the arrangement space portion 2 is reduced. It can be made shallow, and the relative distance between the structure (suspension bolt B ₁ , wall body, etc.) and the object to be held (shake bolt B ₂ ) can be made small (close).

In the first embodiment and its modification, the inner and outer arrangements of the first and second locking claws 14 and 15 and the locked claw 5 are reversed, and the elasticity of the holding members S ₁ and S ₁ 'is reversed. It is also possible to form the first and second locking claws 14 and 15 inside the wall portion 13 and form the locked portion 5 on the deformation preventing claws 3 of the base members V ₁ and V ₁ ′. is there.

Next, with reference to FIG. 15 and FIG. 16, a holder A ₂ of Example 2 of the present invention will be described. As described above, in the holding body A ₂ , the tilt angle θ of the swing bolt B ₂ is mostly in the range of 30 ° to 60 °, and 45 ° is the recommended angle unless there is a restriction on installation. That is, the tilt angle θ of the swing stop bolt B ₂ can be read numerically, and only the principle of reading the tilt angle will be described. Both the base member V ₂ and the holding member S ₂ have the same size, and are regular dodecagonal in a front view. As shown in FIGS. 14 (a) and 14 (b), both members V ₂ and S ₂ are When relatively rotated by 30 ° or 60 °, the outer shapes match in a front view.

For the angle value of the order to decipher the inclination angle, as shown in FIG. 14, each "0" is stamped on the two vertexes facing the two members V _2, S _2, the "0" is engraved “30” and “60” are engraved on each of the two vertices facing in both directions from the vertices. Since the tilting angle of the swing stop bolt B ₂ is never 90 °, the marking of “90” is unnecessary. Also, the 45 ° display line segment T that displays the recommended inclination angle of 45 ° of the swing bolt B ₂ is “30” on the plane formed by the vertices marked with “30” and “60”. A short line segment is engraved in the middle of "60".

Further, the base member V ₂ and the holding member S ₂ have a regular dodecagonal shape when viewed from the front, and the tilt angles θ of 30 °, 45 °, and 60 °, which are frequently used by the swing stop bolt B ₂ , are , By matching the outer shape or by matching the apex with the 45 ° display line segment T, the reading can be performed instantaneously and accurately, and the apex of each member V ₂ , S ₂ should be the reading reference even if the inclination angle is in between. Therefore, it can be analogized.

FIG. 17 shows a state in which two pipe bodies P ′ are connected at different intersecting angles by the holding body A ₃ of the third embodiment. The holding body A ₃ has a structure in which a disk-shaped base member V ₃ and a holding member S ₃ are rotatably connected by the above-described locking structure, and each member V ₃ , S ₃ has a cross section U. A V-shaped elastically deformable holding body 33 is attached by a screw 34. When the pipe body P ′ is inserted into the holding body 33 through the opening 33a in a state where the opening portion of the holding body 33 is elastically deformed, the opening portion of the holding body 33 is restored to its original shape, so that the pipe is attached to the holding body 33. The body P'is held.

Since the base member V ₃ and the holding member S ₃ forming the holding body A ₃ are relatively rotatable, as shown in FIGS. 17A and 17B, the two pipe bodies P 'Can be connected and held in a state where they are crossed at an arbitrary angle.

In Examples 1 and 3, the base member V ₁ (V ₃ ) and the holding member S ₁ (S ₃ ) are rotatably connected to each other, and the suspension bolt B ₁ and the swing-off bolt B ₂ are predetermined. An example has been given in which the pipe members are crossed at an angle and connected, or the two pipe bodies P ′ are connected at a predetermined angle, but for example, the base member is fixedly arranged on the wall surface and is held with respect to the base member. The present invention is also applicable to a case where the member is rotated to change the arrangement angle of the held body held by the holding member with respect to the absolute space and the member is placed on the wall surface.
