Description

According to the present invention, a hole formed in an attachment such as a pedestal, a column, a pipe, and the like and a hole formed in the attachment attached to the attachment are combined to fix the attachment and the attachment. It relates mounting structure of toggle pin, more particularly, to a mounting structure of a toggle pin for fixing a plurality of pipes each having a plurality of holes facing with a predetermined gap.

  FIG. 7 shows a perspective view of a conventional example of this type of toggle pin.

  The toggle pin 110 has a cylindrical main body 112 having a predetermined direction (hereinafter referred to as “X direction”) as a longitudinal direction (that is, long in the X direction), and a stop pivotally attached to the main body 112. Includes gold 120.

  A split groove 114 is formed at the tip of the main body 112, and the stopper 120 is disposed in the split groove 114 and pivotally attached to the main body 112 by a pin 26.

  The pin 26 has a longitudinal direction that is substantially perpendicular to the X direction. In other words, the stopper plate 120 is configured to be rotatable with respect to the main body 112 with the pin 26 substantially orthogonal to the X direction as a rotation axis.

  However, since this type of toggle pin 110 allows the stopper 120 to freely rotate with respect to the main body 112, it is difficult to attach the stopper 120 in a hole formed in an attachment such as a mount or a column. there were.

  In order to solve such a problem, a rotating piece is pivotally attached to the tip of a main body (shaft) provided with a collar at one end so as to be rotatable by a deviation of the center of gravity through a split groove, and a washer is attached to the shaft. And a toggle pin in which a spring is fitted between the washer and the collar, and the rotating piece is held in a straight line with the shaft portion or at a right angle to the shaft portion by the spring and the washer (for example, (See paragraphs [0011] to [0016] and FIGS. 1 to 3 of Patent Document 1.)

Japanese Utility Model Publication No. 6-31957 (paragraphs [0011] to [0016], FIGS. 1 to 3)

  However, even with the toggle pin described in Patent Document 1, when the toggle pin is passed through a plurality of holes facing each other with a predetermined gap, it is difficult to penetrate all of the plurality of holes. There is. Furthermore, there is also a problem that it is difficult to pull out a toggle pin penetrating a plurality of holes from these holes.

  These problems will be described with reference to FIG. Note that the pipe 50 illustrated in FIG. 8 has a longitudinal section of the pipe 50.

  When the toggle pin 110 is passed through the two holes 52 and 54 formed in the pipe 50 with the gap 70, the toggle pin 110 is first inserted into the first hole 52 as shown in FIG. To penetrate. Thereafter, as shown in FIG. 8B, the toggle pin 110 is passed through the second hole 54. Thereafter, the stopper 120 is rotated with respect to the main body 112 by the action of gravity (see a two-dot chain line).

  When the toggle pin 110 is passed through a plurality of opposing holes 52, 54 having a predetermined gap 70, the stop is made after passing through the first hole 52 and before passing through the second hole 54. The gold 120 often rotates with respect to the main body 112.

  At this time, it is difficult to return the main body portion 112 and the clasp 120 to the linear shape again and allow the toggle pin 110 to pass through the second hole 54. Further, it is difficult to pass the toggle pin 110 through the first hole 52 and the second hole 54 while preventing the clasp 120 from rotating with respect to the main body 112.

  Further, when the toggle pin 110 penetrating the two holes 52 and 54 is pulled out from the holes 52 and 54, the main body 112 and the stopper 120 are L-shaped or inverted L-shaped, so that it is easy. Can not be pulled out.

  Note that the stopper 120 is configured to rotate with respect to the main body 112 because the toggle pin 110 penetrating the plurality of holes 52 and 54 does not rely on human intentions from these holes 52 and 54. This is to prevent it from slipping out naturally.

Therefore, with this invention, when allowed to pass through the toggle pin in a plurality of holes facing with a predetermined gap to fix a plurality of pipes, it is possible to readily penetrate into the plurality of holes, through The main object of the present invention is to provide a structure for attaching a toggle pin that can be prevented from naturally coming out of the hole.

In the present invention, the following features are provided alone or in combination as appropriate. A toggle pin mounting structure according to the present invention for solving the above-mentioned problems is pivotally attached to a main body portion that is long in a predetermined direction and one end portion of the main body portion, and is substantially orthogonal to the predetermined direction. A toggle pin having at least a rotation member that is rotatable with respect to the main body portion with the direction as a rotation axis and that forms a plate-like member having a direction extending from the rotation axis as a longitudinal direction, and larger than a predetermined width A first pipe and a second pipe each having a first hole and a second hole facing each other with a gap, and the second pipe is inserted into the first pipe Then, the toggle pin is passed through a first hole group consisting of the first hole of the first pipe and the first hole of the second pipe, and then the first pipe. The second hole and the second pipe have the second hole A the hole with the first by causing through the second hole group consisting of the pipe and the said second pipe securable between the second hole group and the first hole group The toggle pin does not have a member for guiding the rotating member, and the toggle pin is the shortest from the center of the rotating shaft to the tip of the rotating member on the opposite side to the main body with respect to the rotating shaft. The length is larger than the shortest length of the first hole group and the second hole group, and is different from the one end portion of the main body portion on which the rotating member is pivotally attached. Neither the first hole group nor the second hole group can penetrate in a direction provided at the other end and substantially parallel to the rotation direction of the rotation member and substantially perpendicular to the predetermined direction. Projecting from the outer peripheral part of the main body part and projecting part capable of rotating the main body part in the circumferential direction, The rotation of the rotating member relative to the main body at one position when the main body is rotated so that the protrusion is oriented substantially in the vertical direction, and A locking portion having a substantially linear shape in a longitudinal direction of the moving member and a longitudinal direction of the main body portion, and the main body portion is different from the one position by about 180 degrees. rotation to reach the position, has a structure in which the rotary member is a longitudinal direction of the rotating member while rotating intersects with the longitudinal direction of the main body portion relative to the body portion, the The rotating member has the tip part far from the main body part and a terminal part close to the main body part, and is pivotally supported by the rotating shaft between the tip part and the terminal part. While the predetermined direction is substantially horizontal, the protrusions are the same. When the main body is rotated so as to reach the position, the longitudinal direction of the rotating member and the longitudinal direction of the main body are maintained in a substantially linear shape by coming into contact with the end from above. When the main body is rotated so that the protrusion reaches the other position while aligning the predetermined direction substantially horizontally, by releasing the contact of the rotating member above the end portion, The tip portion can be rotated by being pulled by gravity, and the longitudinal direction of the rotating member intersects the longitudinal direction of the main body .

  According to the above configuration, the toggle pin has a rotation direction position where the rotating member rotates with respect to the main body when the main body is rotated in the circumferential direction of the main body and the rotation of the rotating member with respect to the main body. And a rotational position where movement is prevented.

The first pipe and the second pipe each have a first hole and a second hole facing each other with a gap larger than a predetermined width, and the second pipe is connected to the first pipe. Is inserted, a first hole group is formed by the first hole of each pipe, and a second hole group is formed by the second hole of each pipe.

Even when each pipe is fixed by passing the toggle pin through the first hole group and the second hole group in a state where the second pipe is inserted in the first pipe , Since the shortest length from the center of the moving shaft to the tip of the rotating member is larger than the shortest length between the first hole group and the second hole group , the rotating member is set to the first hole group. And the second hole group can be penetrated simultaneously.

According to the first aspect of the present invention, when a plurality of pipes each having a plurality of holes facing each other with a predetermined gap are fixed with a toggle pin, the second pipe is inserted into the first pipe. In this state, the toggle pin can be easily passed through the first hole group and the second hole group, and it is possible to prevent the toggle pin from coming out of the through hole group naturally.

Further, when the rotating member is passed through the first hole group , it is not necessary to consider that the main body portion and the rotating member must be linear. Further, there is a further effect that the trouble of rotating the toggle pin in the circumferential direction of the main body portion does not occur before the rotating member is passed through the first hole group and the second hole group. Play.

  FIG. 1 is a perspective view showing a first embodiment of a toggle pin according to the present invention. The toggle pin 10 includes a main body portion 12 and a stopper 20 pivotally attached to the main body portion 12, and the X direction is the longitudinal direction as in the conventional example.

  In addition, about the pin 26 which connects the main-body part 12 and the clasp 20, since it is the same member as the prior art example shown in FIG.7 and FIG.8, the same code | symbol is attached | subjected.

  At the end of the main body 12 opposite to the X direction, the main body 12 (that is, the toggle pin 10) can be easily rotated in the circumferential direction of the main body 12 (direction A in FIG. 1). A protrusion 28 is provided.

  Next, a connection mode between the main body 12 and the clasp 20 will be described with reference to FIG. 2A and 2B are schematic views showing a connection mode between the main body 12 of the toggle pin 10 shown in FIG. 1 and the clasp 20, wherein FIG. 2A is a plan view and FIG. 2B is a side view.

  2A, a U-shaped split groove 14 is formed in a plan view at an end portion 13 of the main body portion 12 on the X direction side (that is, an end portion on which the stopper plate 20 is pivotally attached). ing.

  2B, the U-shaped bottom portion (that is, the end surface of the split groove 14 on the opposite side to the X direction) 15 of the split groove 14 (see FIG. 2A) has a taper inclined in the X direction. A surface 18 is formed (hereinafter, the tapered surface 18 is referred to as a “tapered surface 18 on the main body 12 side”).

  2A and 2B, the stopper 20 is a plate-like member, and has a tapered surface 24 along the tapered surface 18 on the main body 12 side at the end 21 on the opposite side to the X direction. (The taper surface 24 is hereinafter referred to as “taper surface 24 on the clasp 20 side”). That is, it can be said that the tapered surface 24 on the clasp 20 side is also a surface inclined in the X direction.

  Note that the taper surface 24 on the clasp 20 side does not necessarily have to be completely along the taper surface 18 on the main body 12 side, and as shown in FIG. As long as it can be held in a straight line.

  Holes 16 and 22 (see FIG. 2A) are formed in the main body 12 and the clasp 20, respectively. The clasp 20 is formed in the main body 12 by the pins 26 passing through the holes 16 and 22 so that the tapered surface 24 formed on the end 21 and the tapered surface 18 on the main body 12 side face each other. On the other hand, it is pivotally attached. That is, the stopper plate 20 functions as a rotating member that rotates about the pin 26 as a rotation axis (center of rotation).

  The operation when the toggle pin 10 is passed through a plurality of opposing holes with a predetermined gap will be described with reference to FIG. FIG. 3 is a view showing a mode in which the first pipe 50 and the second pipe 60 inserted in the first pipe 50 are fixed by the toggle pin 10, and are shown in time series from (a) to (c). ing. These pipes 50 and 60 are, for example, pipes for scaffolds that are assembled when construction is performed at a high place.

  When the toggle pin 10 penetrates only the first holes 52 and 62 (hereinafter referred to as “first hole groups 52 and 62”) of the first pipe 50 and the second pipe 60, the clasp 20. Are arranged in the gap 70. At this time, if the tapered surface 18 on the side of the main body 12 is inclined in the X direction from the lower side to the upper side (the mode shown in FIG. 3A), the main body 12 and the clasp 20 are held linearly. The That is, the tapered surface 18 on the main body 12 side functions as a locking portion that prevents the stopper 20 from rotating relative to the main body 12.

  While holding the main body 12 and the clasp 20 in a straight line, the clasp 20 is secured to the second holes 54 and 64 (hereinafter referred to as “second hole group”) of the first pipe 50 and the second pipe 60. 54 (referred to as “54, 64”) (the embodiment shown in FIG. 3B), and then the main body 12 (that is, the toggle pin 10) is moved in the circumferential direction of the main body 12 (direction A in FIG. 3B). ) About 180 degrees, the stopper 20 rotates about the pin 26 with respect to the main body 12 by the action of gravity. Thereby, the main-body part 12 and the clasp 20 become T shape (refer FIG.3 (c)).

  When the stopper 20 is passed through the second hole groups 54 and 64, the first pipe 50 and the second pipe 60 are fixed, but the main body 12 and the stopper 20 By making T into a T-shape, it is possible to prevent the toggle pin 10 from coming off from the first hole groups 52 and 62 and the second hole groups 54 and 64.

  On the other hand, in a mode in which the toggle pin 10 penetrates only the first hole groups 52 and 62 (a mode in FIG. 3A), the clasp 20 rotates with respect to the main body 12 and the main body 12 and the clasp. Even if it becomes T-shaped, the main body 12 and the clasp 20 can be easily made straight by simply rotating the toggle pin 10 about 180 degrees in the circumferential direction of the main body 12.

  In addition, the protrusion part 28 provided in the main-body part 12 has a function as a stopper. That is, since the protruding portion 28 cannot penetrate the first hole groups 52 and 62, it is possible to prevent the toggle pin 10 from penetrating more than necessary.

  As described above, when the clasp 20 is passed through the second hole groups 54 and 64, the main body 12 and the clasp 20 are formed in a T shape, and the protrusion 12 is formed on the main body 12. Thus, the fixing of the first pipe 50 and the second pipe 60 can be prevented from being released regardless of human will.

  In this embodiment, when the clasp 20 rotates with respect to the main body portion 12 from the linear state of the main body portion 12 and the clasp 20, the main body portion 12 and the clasp 20 become T-shaped. However, it may be configured to be L-shaped.

  Further, the toggle pin 10 is arranged in the circumferential direction of the main body 12 so that the main body 12 and the clasp 20 are changed from the T-shaped mode to the linear mode, or from the linear mode to the T-shaped mode. When rotating, it is not always necessary to rotate the toggle pin 10 about 180 degrees. That is, it is considered that the aspect changes from when the toggle pin 10 is rotated about 90 degrees in the circumferential direction of the main body 12.

  Next, a second embodiment of the toggle pin according to the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the part which is the same as that of 1st Embodiment of the toggle pin which concerns on this invention shown in FIGS. 1-3, and it is the same, and it is mainly based on the difference with the said 1st Embodiment below. explain.

  The toggle pin 10a is different from the first embodiment in that the stop pin 20a is prevented from rotating with respect to the main body 12a.

  In the split groove 14a (see FIG. 4A) formed in the main body 12a of the toggle pin 10a, a receiving seat 18a is formed instead of the tapered surface 18 (see FIGS. 1 to 3) on the main body 12 side. ing.

  The receiving seat 18a is a peripheral portion of the main body portion 12a and is formed to protrude in the X direction from the U-shaped bottom portion 15a of the split groove 14a (see FIG. 4A). The stopper 20a is prevented from rotating.

  The clasp 20a is connected to the main body 12a by a hole 22a (see FIG. 4 (a)) formed therein and a pin 26 (see FIG. 4 (b)) penetrating the hole 16a formed in the main body 12a. And pivotally attached.

  Note that a surface substantially orthogonal to the X direction is formed at an end portion 21a in the direction opposite to the X direction of the clasp 20a (that is, the end portion on the main body 12a side).

  When the end 21a of the clasp 20a is supported by the receiving seat 18a (that is, when the receiving seat 18a and the end 21a of the clasp 20a abut), the main body 12a and the clasp 20a are linear. It becomes a held aspect.

  The length of the catch 18a in the X direction is the same as that of the catch 20a until the catch 18a and the end 21a of the catch 20a abut after the catch 20a rotates with respect to the main body 12a. The length does not interfere. That is, in a mode in which the main body portion 12a and the clasp 20a are T-shaped (the clasp 20a is a two-dot chain line in FIG. 4B), the clasp in the direction opposite to the X direction from the center of the pin 26 is used. The sum of the distance L1 to the end of the gold 20a and the length L2 in the X direction of the receiving seat 18a may be smaller than the distance L from the center of the pin 26 to the U-shaped bottom 15a of the split groove 14a. Thereby, the main-body part 12a and the clasp 20a can take any form of a linear form and a T-shape.

  The effect | action about this toggle pin 10a is demonstrated referring FIG.4 (b).

  When the receiving seat 18a is positioned on the side where the gravity acts on the center line 30 (the Y direction in FIG. 4B) (the mode of FIG. 4B), due to the action of gravity, The stopper plate 20a rotates with respect to the main body 12a about the pin 26 as a rotation axis. On the other hand, if the receiving seat 18a is located on the side opposite to the direction in which gravity acts, the receiving seat 18a prevents the stopper 20a from rotating with respect to the main body portion 12a. That is, the receiving seat 18a functions as a locking portion that prevents the stopper 20a from rotating relative to the main body portion 12a.

  Therefore, the operation when the toggle pin 10a according to the second embodiment is passed through two holes facing each other with a predetermined gap is the same as the toggle pin 10 according to the first embodiment.

  Next, a third embodiment of the toggle pin according to the present invention will be described with reference to FIG. In the following description, differences from the above embodiments will be mainly described.

  In the toggle pin 10b, a cutout portion 14b (see FIG. 5A) is formed in the main body portion 12b instead of the split grooves 14 and 14a (see FIGS. 2 to 4). That is, the notch 14b is different from the U-shaped split grooves 14 and 14a in plan view in that the notch portion 14b is L-shaped or inverted L-shaped in plan view.

  A receiving seat 18b is formed in a cutout portion 14b (see FIG. 5A) formed in the main body portion 12b of the toggle pin 10b.

  The receiving seat 18b is formed at the periphery of the main body 12b and projecting in the X direction from the end 15b opposite to the X direction of the notch 14b (see FIG. 4A). The stopper 20b is prevented from rotating with respect to the portion 12b.

  The clasp 20b is connected to the main body 12b by a pin 26 (see FIG. 5B) penetrating through the hole 22b formed therein and the hole 16b formed in the main body 12b (see FIG. 5A). And pivotally attached.

  When the end 21b of the clasp 20b is supported by the receiving seat 18b (that is, when the receiving seat 18b and the tip of the clasp 20b abut), the main body 12b and the clasp 20b are held in a straight line. This is the mode.

  As in the second embodiment, the length of the receiving seat 18b in the X direction is such that the receiving seat 18b and the end portion 21b of the catching plate 20b contact each other after the stopper 20b rotates with respect to the main body portion 12b. The length is such that it does not interfere with the clasp 20b until it comes into contact. Thereby, the main-body part 12b and the clasp 20b can take either a linear form or a T-shaped aspect.

  The operation of the toggle pin 10a is the same as that of the toggle pin 10a according to the second embodiment. Accordingly, the receiving seat 18b functions as a locking portion that prevents the stopper 20b from rotating relative to the main body portion 12b.

  Therefore, the action when the toggle pin 10b according to the third embodiment is passed through two opposing holes with a predetermined gap is the same as that of the toggle pins 10 and 10a according to the first and second embodiments. Become.

  In addition, this toggle pin 10b is replaced with the receiving seat 18b formed in the main-body part 12b, even if the taper surface which inclines in the X direction is formed in the edge part 15b of the notch part 14b similarly to 1st Embodiment. good.

  As described above, the toggle pins 10, 10 a, 10 b of each of the above embodiments are pivotally attached to the main body parts 12, 12 a, 12 b and the main body parts 12, 12 a, 12 b and extend in a direction substantially orthogonal to the X direction. There are stoppers 20, 20 a, 20 b that can rotate with respect to the main body parts 12, 12 a, 12 b with the long pin 26 as a rotation axis. The main body parts 12, 12a, 12b are respectively formed with a tapered surface 18 and receiving seats 18a, 18b on the main body part 12 side that function as locking parts. Here, in the case of the toggle pin 10, when the tapered surface 18 on the side of the main body 12 is inclined in the X direction from the lower side to the upper side, if it is the toggle pin 10a, 10b, the side opposite to the direction in which the gravity acts. When the receiving seats 18a, 18b are positioned, the stoppers 20, 20a, 20b are prevented from rotating with respect to the main body portions 12, 12a, 12b. Therefore, before the toggle pins 10, 10 a, 10 b are penetrated through the first hole groups 52, 62 and through the second hole groups 54, 64, the clasps 20, 20 a, 20 b are attached to the main body parts 12, 12 a, Even if it rotates with respect to 12b, by rotating the toggle pins 10, 10a, 10b in the circumferential direction of the main body parts 12, 12a, 12b, the main body parts 12, 12a, 12b and the clasps 20, 20a are rotated. 20b can be easily returned to a substantially linear shape. Even if the main body portions 12, 12a, 12b and the clasps 20, 20a, 20b are substantially L-shaped, the toggle pins 10, 10a, 10b are similarly connected to the first hole group. 52 and 62 and the second hole groups 54 and 64 can be easily pulled out.

  In each of the above embodiments, the tapered surface 18 on the main body 12 side functions as a locking portion in the case of the toggle pin 10, and the receiving seats 18a and 18b function as locking portions in the case of the toggle pins 10a and 10b. The aspect of a stop part is not restricted to these. That is, when the toggle pins 10, 10a, 10b are rotated in the circumferential direction of the main body parts 12, 12a, 12b, the clasps 20, 20a, 20b for the main body parts 12, 12a, 12b are at least at one position in the rotation direction. The latching part which suppresses rotation of this should just be formed or provided in the main-body part 12, 12a, 12b side. In other words, rotation in which the clasps 20, 20a, 20b rotate with respect to the main body parts 12, 12a, 12b in the rotation direction of the main body parts 12, 12a, 12b with the center lines 30, 30a, 30b as rotation axes. What is necessary is just to have a direction position and the rotation direction position by which rotation of the clasp 20,20a, 20b with respect to the main-body parts 12,12a, 12b is suppressed. The “rotation direction position” includes a case where there is a predetermined angle range in the rotation direction of the main body parts 12, 12a, 12b with the center lines 30, 30a, 30b as rotation axes.

  Further, in the toggle pin according to the present invention, it is preferable that the conventional clasp 20 and the clasps 20, 20a, 20b of the above embodiments are made longer. This will be described as a fourth embodiment with reference to FIGS. 6 (a) to 6 (c). In the following description, differences from the above embodiments will be mainly described.

  When this toggle pin 10c is passed through a plurality of opposing holes with a gap larger than 40 mm, the length of the gap, that is, the distance between the plurality of holes through which the toggle pin 10c is to be passed is determined in advance. This is particularly effective when used for fixing an attachment and an attachment. This is because the maximum length defined by the JIS standard is 40 mm.

  The “gap larger than 40 mm” means that the shortest distance D between the inner surfaces of the first hole groups 52 and 62 and the inner surfaces of the second hole groups 54 and 64 is larger than 40 mm. To do.

  The toggle pin 10c is pivotally attached to the main body portion 12 in place of the clasp 20 of the toggle pin 10 described in the first embodiment.

  The stopper plate 20c is a plate-like member having the X direction as a longitudinal direction (that is, long in the X direction). More specifically, the shortest length H from the center of the pin 26 (the center of rotation of the stopper 20c relative to the main body 12) to the tip of the stopper 20c on the X direction side is the size of the gap 70, that is, the first It is larger than the shortest distance D (D> 40 mm) between the inner surface of the first hole group 52, 62 and the inner surface of the second hole group 54, 64.

  Further, the length in the X direction of the clasp 20c is more preferably 50 mm or less, but it is not particularly limited to this length.

  By making the length of the clasp 20c in the X direction larger than 40 mm, as shown in FIG. 6 (a), the clasp 20c can be attached to the first hole group 52, 62 and the second hole group 54, 64 can be penetrated simultaneously. That is, when the clasp 20c is passed through the second hole groups 54 and 64, the center of rotation of the clasp 20c with respect to the main body 12 (the center of the pin 26) still passes the first hole groups 52 and 62. An aspect that does not penetrate (the aspect of FIG. 6A) may occur.

  Therefore, the stopper 20c is rotated with respect to the main body 12 after the stopper 20c is passed through the first hole groups 52 and 62 and before the second holes 54 and 64 are passed through. There is nothing to do. Thereby, when the clasp 20c is penetrated through the first hole groups 52 and 62, it is not necessary to consider that the main body 12 and the clasp 20c must be linear. Furthermore, before the clasp 20c is passed through the first hole groups 52 and 62 and the second hole groups 54 and 64, the trouble of rotating the toggle pin 10c in the circumferential direction of the main body portion 12 occurs. There is nothing.

  Thus, when the toggle pin 10c penetrated through the first hole group 52, 62 and the second hole group 54, 64 is rotated in the circumferential direction of the main body part 12 (A direction in FIG. 6), the main body part 12 and the clasp 20c are changed from the linear form (the form of FIG. 6B) to the L-shaped form (the form of FIG. 6C).

  As in the first embodiment, a taper surface 24c along the taper surface 18 on the main body 12 side (hereinafter referred to as “taper on the clasp 20 side” is provided at the end 21c in the direction opposite to the X direction of the clasp 20c. A surface 24c ").

  As a result, as in the first to third embodiments, the toggle pins 10c penetrating through the first hole groups 52 and 62 and the second hole groups 54 and 64 facing each other with the gap 70 are removed. The holes 52, 54, 62, and 64 can be easily pulled out.

  In this specification, “U-shape”, “U-shape”, “T-shape” and “L-shape” are respectively U-shape, U-shape, T-shape and L-shape in the strict sense. As well as meanings of U, U, U, and L. Further, “the main body portion and the clasp are held in a straight line” means not only a straight line in a strict sense but also the toggle pin 10 in the first hole groups 52 and 64 and the second hole groups 54 and 64. , 10a, 10b, 10c means that it may be substantially straight so that it can penetrate.

  Further, in this specification, “to rotate the toggle pin in the circumferential direction of the main body” means “toggle the pin through the center of the cross section of the main body substantially perpendicular to the X direction and substantially in the X direction. It means “rotating a parallel line as a rotation axis”. “Rotating in the circumferential direction” can also be referred to as “rotating along the circumferential direction”. In addition, “a line passing through the center of the cross section of the main body substantially perpendicular to the X direction and substantially parallel to the X direction” may be referred to as a “center line of the main body”. Furthermore, “the center of the main body” means “the center of gravity of the main body”.

  In this specification, “substantially orthogonal” and “substantially parallel” mean that the case includes completely orthogonal and parallel, respectively.
