Description

  The present invention relates to a bolt that penetrates a bolt through-hole opened in a positioning target member and protrudes from a closed space behind the bolt, and is screwed in the closed space on the rear side so that the positioning target member is connected to the shaft of the bolt. The present invention relates to a positioning nut that is positioned at any position in the direction and is operable from the front side of the positioning target member.

  When positioning the positioning target member on the bolt that penetrates the bolt through hole of the positioning target member, the positioning nut is positioned behind the positioning target member, and the rear side of the positioning target member is manipulated by some obstacle When it is impossible to do this, that is, when the rear side is substantially a closed space, a positioning nut configured to be operable from the front side of the positioning target member is not provided. It seems not to have been proposed.

  Patent Document 1 relates to a height adjusting leg of a vending machine or the like, which includes a leg portion and a male screw erected and fixed to the collar, and an upper fixed screw provided on the upper end of the male screw. The female screw is screwed onto the male screw of the leg body, and the bottom plate of a vending machine or the like whose height is to be adjusted is placed on the upper end of the female screw. It is penetrated through the stop hole so that it can move up and down and cannot rotate.

  Therefore, according to the height adjusting leg of this Patent Document 1, if the female screw is rotated, the female screw can be moved up and down according to the rotation direction. Therefore, the bottom plate mounted thereon can be adjusted up and down. However, in the configuration of the height adjustment leg of Patent Document 1, when the lower part of the bottom plate of the vending machine or the like is a space closed for some reason, the rotation of the female screw cannot be performed. It will not be possible.

  Patent Document 2 relates to a support leg for a flooring material, in which a nut portion is screwed to a bolt body standing on a substrate, a disk-like support panel is fixed on the nut portion, A floor panel support is arranged on a support panel so as to be rotatable with respect to each other.

  Therefore, when the support panel is rotated, the nut portion is rotated at the same time, and the nut portion is moved up and down in accordance with the rotation direction, and the floor panel receiver is also moved up and down through the support panel that is moved up and down accordingly. Since the floor panel receiver is arranged so as to be rotatable with respect to the support panel, the floor panel receiver can be kept stationary even by the rotation of the support panel.

  The support leg of the flooring material of this Patent Document 2 also rotates the lower support panel and the nut part of the floor panel receiver as described above, and when the lower part of the floor panel is closed for some reason, The elevation adjustment operation cannot be performed.

  Patent Document 3 relates to an adjuster mechanism with a seat, which is a plate-like seat having a female screw at the center and an adjuster screw threaded through the female screw of the seat, and at the same time directly above the seat. The lock nut is screwed together, and is composed of an adjuster screw having a knob at the upper end and a pad at the lower end.

  This is done by making a hole in the bottom of the device that needs to be adjusted up and down, projecting the part below the pad and adjuster screw seat downward from the hole, fixing the seat to the hole, and removing the knob. By rotating, the length of the adjuster screw protruding downward is adjusted, and the height of the target device is adjusted. The height adjustment is performed above the device, but this is the one that the adjuster screw can move, and does not position the positioning object at any position of the fixed bolt.

Consists of a rotation operated part that can be rotated by an operation means,
A positioning nut is provided in combination with an operating nut-like member provided with the operating means and not provided with a female screw that can be slidably mounted on the bolt.

2 of the present invention is the positioning nut of 1 of the present invention,
The rotation operated part is
A cylindrical passive base that can be gently inserted into the bolt through-hole of the target member, extending in a cylindrical shape from the end of the nut body along the female screw portion,
It is composed of a halved passive locking portion extended from the cylindrical passive base by an angular width of 180 degrees in the circumferential direction,
The operating means;
A cylindrical driving base extending from the end of the operation nut-shaped member along the inner periphery thereof;

The rotation operated part is
A cylindrical passive base extending in a cylindrical shape from the end of the nut body along the female screw portion;
The tubular passive base further comprises two quadrant passive locking portions each extending at an angular interval of 180 degrees in the circumferential direction with an angular width of 90 degrees in the circumferential direction.
The operating means;
A cylindrical driving base extending from the end of the operation nut-shaped member along the inner periphery thereof;
The cylindrical drive base is further composed of two four-part drive locking portions each extending at an angular width of 90 degrees in the circumferential direction and at an angular interval between the centers of 180 degrees in the circumferential direction.

  According to the positioning nut 1 of the present invention, the positioning nut screwed to the bolt behind the positioning target member is rotated from the front side of the positioning target member with the operation nut-like member, and freely above the bolt. The positioning target member can be easily positioned through this.

  The operation nut-like member is externally attached to the bolt on the front side of the member to be positioned and moved to the positioning nut side, and the operating means is engaged with the rotation operated portion of the positioning nut through the bolt through hole. Stop. Then, the positioning nut is rotated by rotating the nut-like member for operation in a desired rotation direction using means such as a socket wrench, and the bolt is moved in a direction according to the rotation direction. Accordingly, the positioning target member can be positioned. As described above, the positioning nut can be easily operated freely on the front side of the positioning target member, and there is no problem even if the positioning nut cannot be operated on the rear side.

  Here, the closed space does not mean only when the positioning nut is literally in the completely closed space, and the positioning nut cannot be directly operated in the space. In such a case, such a space is referred to as a closed space.

  According to the positioning nut 2 of the present invention, when the positioning target member is positioned with the positioning nut screwed to the bolt behind the positioning target member, the positioning target member is easily and reliably performed as follows. Is possible.

  When the positioning nut is arranged behind the positioning target member as described above, the cylindrical passive base and the half passive locking portion which are the rotationally operated portions are placed in the bolt through holes through which the bolts are penetrated. It shall be in the approach state. On the other hand, the nut-like member for operation is externally attached to the bolt on the front side of the member to be positioned, and further moved to the side of the positioning nut, and the cylindrical drive base and the half-drive engaging portion as the operation means are Enter the bolt through hole.

  At this time, when the circumferential angle between the rotation operated portion and the operating means is in a corresponding relationship, the mutual engagement immediately occurs, but it is quite in a corresponding relationship. Therefore, if the operation nut-like member is slightly rotated while being pushed toward the positioning nut, the operation nut-like member advances at the moment when the corresponding relationship is reached, and half of the rotationally operated portion of the positioning nut is obtained. The inner side surfaces of the split passive locking portion and the half drive locking portion of the operating means of the operation nut-shaped member come into contact with each other, and both are locked.

  Thereafter, if the operation nut-like member is rotated, the positioning nut rotates in the corresponding rotation direction via the operation means and the rotation operated part, and moves on the bolt in the direction corresponding to the rotation. Become. Thus, the positioning nut can be freely moved in a desired direction, and the positioning target member can be freely positioned through this. Moreover, these structures are simple and have the advantage of being easily manufactured.

  According to the positioning nut 3 of the present invention, in the case where the positioning target member is positioned with the positioning nut screwed to the bolt behind the positioning target member, as in the positioning nut 2 of the present invention, It is possible to do it easily and reliably.

  When the positioning nut is disposed behind the positioning target member as described above, the cylindrical passive base portion and the four-part passive locking portion, which are the rotationally operated portions, are placed in the bolt through holes through which the bolts are passed. It shall be in the approach state. On the other hand, the nut-like member for operation is externally attached to the bolt on the front side of the member to be positioned, and is further moved to the side of the positioning nut. Enter the bolt through hole.

  At this time, if the circumferential angle between the rotationally operated portion and the operating means is in a corresponding relationship, they are immediately locked with each other, but in many cases, such a corresponding relationship is not achieved. Therefore, if the operation nut-like member is slightly rotated while being pushed toward the positioning nut, the operation nut-like member advances at the moment when the corresponding relationship is reached during the rotation, and the rotation-operated portion 4 of the positioning nut is operated. The inner side surfaces of the divided passive locking portion and the four-part drive locking portion of the operating means of the operation nut-shaped member come into contact with each other, and both are locked.

  Thereafter, when the operation nut-like member is rotated, the positioning nut rotates in the corresponding rotation direction via the operation means and the rotation operated portion, and moves on the bolt in the direction corresponding to the rotation. Become. Thus, the positioning nut can be freely moved in a desired direction, and through this, the member to be positioned can be freely moved and positioned at a desired position. Moreover, these structures are simple and have an advantage that they can be easily manufactured.

  The best mode for carrying out the invention will be described in detail with reference to the drawings based on the embodiments.

  As shown in FIGS. 1 (a) to 1 (f), the positioning nut 1 of this embodiment basically includes a nut body 1a and a rotationally operated portion 1b projected from the end surface of the nut body 1a. The operation means 2a is combined with the operation nut-like member 2 that does not have a female screw on the inner periphery that protrudes from one end.

  The nut main body 1a is provided with a female screw part fs that can be screwed into a target bolt b on the inner periphery thereof, and an end face provided with the rotation operated part 1b is used as a surface on the side in contact with the positioning target member B. .

  As shown in FIGS. 1 (d) to (f), the rotary operated portion 1b includes a cylindrical passive base 1b1 extending in a cylindrical shape from the end of the nut body 1a along the female screw portion fs, It comprises a half-passive locking portion 1b2 further extended from the tip of the cylindrical passive base portion 1b1. The cylindrical passive base 1b1 is set so that its outer diameter can be gently inserted into the bolt through hole BH of the positioning target member B. Further, the halved passive locking portion 1b2 is set so that its circumferential width is an angular width of 180 degrees.

  The operation nut-like member 2 is shown in FIGS. 1A to 1C, and as described above, the operation means 2a is protruded from one end thereof. The operation means 2a is shown in FIG. As described above, a cylindrical drive base 2a1 extending in a cylindrical shape along the inner periphery from the end of the nut-like member 2 for operation, and a half drive locking portion 2a2 further extended from the cylindrical drive base 2a1 It is composed of The outer diameter of the cylindrical drive base 2a1 is set so that it can be gently inserted into the bolt through hole BH of the positioning target member B, just like the cylindrical passive base 1b1 of the positioning nut 1. Also, the half drive locking portion 2a2 is set so that the circumferential width thereof is an angular width of 180 degrees, just like the half passive locking portion 1b2 of the positioning nut 1.

  The positioning nut 1 and the operation nut-like member 2 described above are all integrally formed of metal.

  As shown in FIG. 2, using the positioning nut 1 and the operation nut-like member 2 of the above-described embodiment, the positioning target member B in a mode in which the side plate is suspended from the peripheral side portion toward the lower side (rear side). An example of positioning in the height direction will be described.

  The upright bolt b is fixed at the lower part, and the positioning nut 1 is screwed onto the bolt b in a state where the rotary operated portion 1b is placed in advance, and then the positioning target member B is attached to the bolt. Set to b. As shown in FIG. 2 (a), the positioning target member B is set by penetrating the bolt b into the central bolt through hole BH in the downward state of the side plate as shown in FIG. 2 (a). At this time, between the inner peripheral surface of the bolt through-hole BH of the positioning target member B and the bolt b, the rotationally operated portion 1b of the positioning nut 1 is brought into an entering state. Thus, the lower surface of the positioning target member B comes into contact with the upper surface of the positioning nut 1.

  In the state shown in FIG. 2 (a), it is clear that the positioning object B can be adjusted up and down by rotating the positioning nut 1 and adjusting it up and down. The side plate is suspended, and the positioning nut 1 inside the side plate cannot be easily rotated. That is, the positioning nut 1 is located in a closed space in the above-described sense.

  Therefore, as shown in FIG. 2 (a), the operation nut-like member 2 is externally mounted on the bolt b from its upper end with the operation means 2a facing downward, as shown in FIG. 2 (b). Lower. The operating means 2a is inserted into the bolt through hole BH from above, and this is locked to the rotationally operated portion 1b of the positioning nut 1. In many cases, the operating nut 2 is slightly rotated because the operating means 2a is simply not lowered into the bolt through-hole BH because the two are not locked. When the operating means 2a and the rotary operated portion 1b are in a mutually corresponding relationship in the process of rotation, as shown in the figure, the operating means 2a of the operating nut-like member 2 descends at that moment, The inner side surfaces of the split drive locking portion 2a2 and the half passive locking portion 1b2 of the rotationally operated portion 1b of the positioning nut 1 come into contact with each other, and both are locked.

  Thereafter, as shown in the figure, if the operation nut-like member 2 is rotated using a socket wrench sw or the like, the positioning nut 1 rotates correspondingly via the operation means 2a and the rotation operated portion 1b. It rotates in the direction and moves on the bolt b in the direction corresponding to the rotation. Thus, the positioning nut 1 can be freely moved in a desired direction, and the positioning target member B can be freely positioned through this. In this example, as shown by the arrow a1, since it is rotated counterclockwise as viewed from above, the positioning nut 1 is raised as shown in FIG. 2 (b), and the positioning target member B is also raised accordingly. Will be positioned.

  After that, if it is necessary to fix the positioning target member B placed on the upper end surface of the positioning nut 1 more than the positioning by simply placing it, the operation may be performed as shown in FIG. With the nut-like member 2 set, the fastening nut 3 is screwed onto the bolt b from above, and is rotated and tightened as shown by the arrow a2, so that the operation nut-like member 2 is interposed. Thus, the positioning target member B is positioned and fixed by the positioning nut 1 and the tightening nut 3.

  As shown in FIG. 2 (c), the upper surface of the positioning target member B is such that the lower surface of the operation nut-like member 2 is in the locked state between the operating means 2 a and the rotationally operated portion 1 b of the positioning nut 1. Applies when in contact.

  In other cases, as shown in FIG. 2 (d), after removing the operation nut-like member 2, the tightening nut 3 is screwed into the bolt b and is rotated as indicated by an arrow a3. The positioning target member B is directly clamped and fixed by the positioning nut 1 and the tightening nut 3.

As can be understood from FIG. 2 (d), the lower surface of the operation nut-like member 2 is in a locked state between the operation means 2 a and the rotation operated portion 1 b of the positioning nut 1, and the positioning target member B It can be applied regardless of whether it is in contact with the upper surface.
In FIG. 2, w is a washer.

  As described above, according to the positioning nut 1 of this embodiment, even when it is located in a closed space and cannot be operated directly in the space, the positioning operation can be easily performed from the outside. In addition, there is an advantage that the structure is simple and can be easily manufactured.

Next, other embodiments will be outlined.
As shown in FIGS. 3A to 3F, the positioning nut 11 according to another embodiment is basically composed of a nut main body 11a and a rotationally operated portion 11b projected from the end surface of the nut main body 11a. The operation means 12a is configured to be combined with an operation nut-like member 12 that does not have an internal thread on the inner periphery that protrudes from one end.

  The nut main body 11a is provided with a female thread portion FS that can be screwed into a target bolt on the inner periphery thereof, and an end surface provided with the rotation operated portion 11b is used as a surface that comes into contact with a positioning target member.

  As shown in FIGS. 3 (d) to (f), the rotary operated portion 11b includes a cylindrical passive base portion 11b1 extending in a cylindrical shape from the end portion of the nut body 11a along the female screw portion FS, The four-part passive locking portions 11b2 and 11b2 are further extended from the front end of the cylindrical passive base portion 11b1 with an angular width of 90 degrees in the circumferential direction and extended at an angular interval between the centers of 180 degrees in the circumferential direction. The cylindrical passive base portion 11b1 is set so that its outer diameter can be gently inserted into the bolt through hole of the positioning target member.

  The operation nut-like member 12 is shown in FIGS. 3 (a) to 3 (c). As described above, the operation means 12a is projected from one end thereof, and the operation means 12a is shown in FIG. As described above, the cylindrical drive base 12a1 extending from the end of the operation nut-shaped member 12 along the inner periphery thereof, and the cylindrical drive base 12a1 each further at an angular width of 90 degrees in the circumferential direction. Further, it is composed of two four-part drive locking portions extended at an angular interval between the centers of 180 degrees in the circumferential direction. The cylindrical drive base 12a1 is set to have an outer diameter that can be gently inserted into the bolt through-hole of the positioning target member, just like the cylindrical passive base 11b1 of the positioning nut 11. .

  The positioning nut 11 and the operation nut-like member 12 described above are all integrally formed of metal.

  Therefore, according to the positioning nut 11 of the other embodiment, when positioning the positioning target member with the positioning nut 11 screwed to the bolt behind the positioning target member, It can be done easily and reliably as well.

  Similar to the positioning nut 1 of the above embodiment, when the positioning nut 11 is arranged behind the positioning target member, the cylindrical passive base portion 11b1 and the four-part passive locking portions 11b2 and 11b2 which are the rotation operated portions 11b are provided. It is assumed that the bolt is inserted into a bolt through hole through which the bolt is passed. On the other hand, the operation nut-like member 12 is externally attached to the bolt on the front side of the positioning target member, and is further moved to the positioning nut 11 side, and the cylindrical drive base 12a1 which is the operation means 12a and the 4-split drive mechanism. Stop parts 12a2 and 12a2 are made to enter the bolt through holes.

  At this time, if the rotational angle of the rotation operated portion 11b and the operating means 12a are in a corresponding relationship, they are immediately locked, but in many cases, such a corresponding relationship is obtained. Therefore, if the operation nut-like member 12 is slightly rotated while pushing the positioning nut 11 toward the positioning nut 11 or applying a load due to its own weight, the operation nut-like member 12 is instantly in a corresponding relationship during rotation. 4a and 4b, as shown in FIGS. 4 (a) and 4 (b), two quadrant passive locking portions 11b2 and 11b2 of the rotationally operated portion 11b of the positioning nut 11 and the nut-like member 12 for operation are provided. The inner side surfaces of the two four-part drive locking portions 12a2 and 12a2 of the operating means 12a come into contact with each other, and both are locked.

  Therefore, after that, if the operation nut-like member 12 is rotated, the positioning nut 11 rotates in the corresponding rotation direction via the operation means 12a2 and the rotation operated portion 11b, and the rotation on the bolt corresponds to the rotation. Will move in the direction. In this way, the positioning nut 11 can be freely moved in a desired direction, and through this, the member to be positioned can be freely moved and positioned at a desired position. Moreover, these structures are simple and have an advantage that they can be easily manufactured.
