Description

  The present invention relates to a plug mounting device for mounting various plugs such as gas plugs and water taps on a mounting surface such as a floor surface or a wall surface.

  As described in Patent Document 1 below, this type of conventional stopper mounting device includes a ring-shaped frame body having two bolt insertion holes on the inner periphery, and each bolt insertion hole of the frame body. The inserted bolts, the clamping members rotatably inserted at the front ends of the bolts, and the distal ends of the two bolts are screwed into the one end and the other end, respectively. And a movable member. When the bolt is rotated in one direction, the movable member moves so as to approach the frame, and the holding member is moved toward the frame by the movable member.

  When a faucet is attached to the floor using the stopper attachment device having the above-described configuration, a through hole is formed in advance at a location where the faucet of the floor board is attached. Further, the clamping member is positioned at an insertion position where the clamping member can be inserted into the through hole. The movable member is formed in a shape and size that can be inserted into the through hole.

  When prepared in this way, the movable member and the clamping member are inserted into the through hole, and the frame body is abutted against the floor surface. Thereafter, the bolt is rotated in one direction. At the beginning of the rotation of the bolt, the clamping member rotates together with the bolt from the insertion position to the clamping position by the frictional resistance acting between the inner circumferential surface of the clamping member and the outer circumferential surface of the bolt. When the clamping member is located at the clamping position, a part of the clamping member is located on the outer side in the radial direction from the inner peripheral surface of the through hole. Therefore, when the bolt is further rotated in one direction and the holding member is moved to the frame body side by the movable member, the holding member hits the lower surface of the floor plate. As a result, the sandwiching member and the frame sandwich the floor plate, and the frame is fixed to the floor surface. Then, a faucet is attached to the frame. Thereby, the faucet is attached to the floor surface.

JP 2000-120122 A

  In the plug mounting device having the above configuration, the clamping member is rotated from the insertion position to the clamping position by the frictional resistance acting between the outer peripheral surface of the bolt and the inner peripheral surface of the clamping member. However, the frictional resistance acting between the bolt and the clamping member is small. For this reason, when the bolt is rotated in one direction, the holding member may not be rotated together with the bolt but may be maintained in a stopped state at the insertion position. In such a case, even if the bolt is tightened, the clamping member only moves to the frame side at the insertion position, and the clamping member does not hit the lower surface of the floor board. For this reason, a frame cannot be fixed to a floor surface and a faucet cannot be fixed to a floor surface.

In order to solve the above problems, the present invention provides a ring-shaped frame body in which a plurality of bolt insertion holes are formed, a plurality of bolts respectively inserted into the bolt insertion holes of the frame body, and the plurality of the plurality of bolts. A movable member that engages with the bolt so as to be movable in the axial direction of the bolt, and a plurality of clamping members respectively provided on the plurality of bolts, wherein at least one of the plurality of clamping members is clamped In the plug mounting device in which the member is rotated from a predetermined insertion position to a predetermined clamping position by a frictional resistance acting between the clamping member and the bolt, the movable member is moved when the clamping member moves to the frame body side. The movable member is engaged with the clamping member so that the movable member moves together with the clamping member, and the bolt is inserted into the movable member so as to be movable in the axial direction and rotatable. Both are characterized by being screwed into the clamping member.
In this case, it is desirable that all of the plurality of clamping members are rotated from the insertion position to the clamping position by frictional resistance acting between the bolts.
Further, an urging means is provided between the frame and the movable member so as to press the movable member against the clamping member so that the movable member moves together with the clamping member in the axial direction of the bolt. It is desirable that
Further, the movable member is formed with a pair of ring portions that are spaced apart from each other in the axial direction of the bolt, and through which the bolt is movable and rotatable. It is desirable that a part of the clamping member is inserted between the ring parts, and the bolt is screwed into the part.

  According to the present invention having the above-described characteristic configuration, since the bolt is screwed to the clamping member, one clamping member of the plurality of clamping members is inserted by the frictional resistance acting between the screw surfaces of the clamping member and the clamping member. It is rotated from the position to the clamping position. Here, the frictional resistance acting between the screw surfaces of the clamping member and the bolt is significantly larger than the frictional resistance acting between the inner peripheral surface of the clamping member and the outer peripheral surface of the bolt. Therefore, the reliability when the clamping member rotates from the insertion position to the clamping position with the rotation of the bolt can be greatly improved.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 11 show a first embodiment of a stopper mounting device according to the present invention. The plug mounting device 1 of this embodiment is for mounting the gas plug G to the floor board F as shown in FIGS. 10 and 11, and as shown in FIGS. 3. A movable member 4 and a clamping member 5 are provided. The plug mounting device 1 can also mount a plug other than the gas plug G, for example, a water plug to the floor F, and can also attach a plug such as the gas plug G to the wall plate.

  The frame 2 has a circular ring shape, and the outer diameter thereof is larger than the through hole Fa formed in the floor board F. The inner diameter of the frame 2 may be larger than the through hole Fa, but it is desirable to make it smaller than the through hole Fa as in this embodiment. A pair of centering protrusions 2a, screw protrusions 2b, and positioning protrusions 2c are formed on the inner periphery of the frame 2 one by one.

  The pair of centering protrusions 2a protrudes downward in the axial direction from the frame 2, and are disposed 180 degrees apart in the circumferential direction on one circumference centered on the center of the frame 2. . The passing outer diameter of the pair of centering protrusions 2a, 2a (the distance between the outer surfaces of the pair of centering protrusions 2a, 2a) is smaller than the inner diameter of the through hole Fa, but the difference is slight. . Therefore, when the centering protrusions 2a and 2a are inserted into the through holes Fa, the center of the frame body 2 substantially coincides with the center of the through hole Fa.

  The screw protrusion 2b protrudes radially inward from the inner periphery of the frame 2. The pair of screw protrusions 2b are spaced apart from each other by 180 ° in the circumferential direction, and are disposed approximately 45 ° away from each other in the circumferential direction with respect to the positioning protrusion 2a. Each protruding portion 2b is formed with a bolt insertion hole 2d that passes through the protruding portion 2b in the axial direction of the frame body 2. The bolt insertion hole 2d is disposed so as to be positioned inside the through hole Fa when the center of the frame body 2 is aligned with the center of the through hole Fa. The bolt 3 is inserted through the bolt insertion hole 2d from the top to the bottom. Of course, the bolt 3 is rotatably inserted into the bolt insertion hole 2d.

  The positioning protrusion 2 c protrudes radially inward from the inner periphery of the frame 2. The pair of positioning projections 2c are spaced apart from each other by 180 ° in the circumferential direction, and are disposed 90 ° apart from each other in the circumferential direction with respect to the screw projection 2b. The positioning protrusion 2c is formed with a screw hole 2e that passes through the positioning protrusion 2c in the axial direction of the frame 2. The screw hole 2e is disposed so as to be positioned on the radially inner side of the through hole Fa when the axis of the frame body 2 is aligned with the axis of the through hole Fa. The screw hole 2e may be disposed outside the through hole Fa.

  The movable member 4 is substantially U-shaped, and screw insertion holes 4a are formed at both ends thereof. In each screw insertion hole 4a, a screw portion 3a of a bolt 3 penetrating the bolt insertion hole 2d is inserted so as to be rotatable and movable in the axial direction thereof. Since the bolts 3 are respectively inserted into the two screw insertion holes 4a, when the bolt 3 is rotated, the movable member 4 is prevented from rotating together with the bolt 3. When the movable member 4 has the axis of the frame 2 substantially coincident with the axis of the through hole Fa, most of the movable member 4 except for the intermediate portion is located inside the through hole Fa, and only the intermediate portion of the through hole Fa. It is formed so as to protrude radially outward. However, the amount of protrusion from the through hole Fa at the intermediate portion of the movable member 4 is small, and the axis of the frame body 2 is set based on the difference between the outer diameter of the centering protrusions 2a and 2a and the inner diameter of the through hole Fa. By moving the frame body 2 from the intermediate portion side to the open portion side of the movable member 4 within a range in which the movable member 4 can be displaced with respect to the axis of the through hole Fa, the movable member 4 is moved from the upper side to the lower side. Can be inserted. In order to save the trouble of shifting the axis of the frame 2 from the axis of the through hole Fa when the movable member 4 is inserted into the through hole Fa, the axis of the frame 2 is used as the axis of the through hole Fa for the movable member 4. And the entire movable member 4 may be formed in a shape and size that can enter the through hole Fa.

  The clamping member 5 is made of a plate material, and has a contact plate portion 5a and a screw insertion portion 5b. The contact plate portion 5a has a substantially rectangular shape, and a screw insertion portion 5b is integrally formed at an intermediate portion of one side portion extending in the longitudinal direction. Whereas the screw insertion portion 5b is arranged so as to be orthogonal to the bolt 3, the abutment plate portion 5a is inclined so as to go upward (to the frame body 2 side) as the distance from the screw insertion portion 5b increases. ing. In other words, the connecting portion between the contact plate portion 5a and the screw insertion portion 5b is bent by the inclination angle of the contact plate portion 5a.

  A screw hole 5c is formed in the screw insertion portion 5b. The lower end portion of the screw portion 3a of the bolt 3 that passes through the screw insertion hole 4a of the movable member 4 is screwed into the screw hole 5c. Therefore, when the bolt 3 is rotated in a state where the rotation of the clamping member 5 is prevented, the clamping member 5 moves in the vertical direction. The end of the movable member 4 is placed on the screw insertion part 5b. Accordingly, when the clamping member 5 moves in the vertical direction, the movable member 4 moves in the vertical direction following the movement. In particular, in the plug mounting device 1 of this embodiment, a coil spring (biasing means) 6 is provided between the movable member 4 and the frame 2 in a state of being externally attached to the bolt 3. The movable member 4 is biased downward by the coil spring 6 and pressed against the screw insertion portion 5 b of the clamping member 5. Therefore, when the clamping member 5 is moved in the vertical direction, the movable member 4 follows the clamping member 5 and moves in the vertical direction. The coil spring 6 is pressed against the screw insertion portion 5b of the clamping member 5 by its own weight when the axis of the frame body 2 is directed in the vertical direction as in the case where the gas plug G is attached to the floor board F. So it is not always necessary. On the other hand, when the gas stopper G is attached to a vertical wall surface, it is almost essential when the axis of the frame 2 is oriented in the horizontal direction.

  Each clamping member 5 can rotate around the bolt 3 with respect to the movable member 4 by rotating together with the bolt 3 or by rotating with respect to the bolt 3. The rotation range of the clamping member 5 with respect to the movable member 4 is between the clamping position shown in FIGS. 1 to 5 and the insertion position shown in FIGS. 6 and 7 when the movable member 4 is on the screw insertion portion 5b. It is regulated. The clamping position of each clamping member 5 is determined by the one side outer peripheral surface of the screw insertion portion 5b abutting against the locking projections 4b provided at both ends of the movable member 4, respectively. The insertion position of each clamping member 5 is determined by the outer peripheral surface of the other side portion of the screw insertion portion 5b abutting against the locking projection 4b. Therefore, in this embodiment, the locking protrusion 4b of the movable member 4 and the screw insertion portion 5b prevent rotation of the clamping member 5 from exceeding the clamping position in the direction from the insertion position toward the clamping position. The mechanism is configured.

  When the clamping member 5 is located at the clamping position, the contact plate portion 5a is positioned on the outer side in the radial direction of the frame body 2 from the bolt 3, and at least a part of the contact plate portion 5a is located inside the through hole Fa. Projects radially outward from the peripheral surface. Therefore, when the clamping member 5 is moved upward in a state where the axis of the frame body 2 is substantially coincident with the axis of the through hole Fa, the two contact plate portions 5a and 5a abut against the lower surface of the floor plate F. Therefore, when the abutting plate portions 5a and 5a are abutted against the lower surface of the floor plate F in a state where the frame 2 is abutted against the floor surface of the floor plate F, the frame body 2 and the sandwiching members 5 and 5 sandwich the floor plate F up and down. . As a result, the frame body 2 is pressed and fixed to the floor surface of the floor board F, and as a result, the stopper mounting device 1 is fixed to the floor board F.

  The insertion position of the clamping member 5 is a position that is substantially 180 ° away from the clamping position with the bolt 3 as the center with respect to the clamping position. When the clamping member 5 is positioned at the insertion position, the contact plate portion 5a is positioned on the radially inner side of the frame body 2 from the bolt 3, and the two clamping members 5 and 5 can simultaneously pass through the through hole Fa. It becomes like this. In particular, in this embodiment, in order to insert the movable member 4 into the through hole Fa, the two clamping members 5 and 5 are provided even when the axis of the frame 2 is shifted from the axis of the through hole Fa by a predetermined distance. It can pass through the through holes Fa simultaneously.

  When the gas stopper G is attached to the floor board F using the stopper attachment device 1 having the above-described configuration, the distance between the lower surface of the frame 2 and the upper surface of the holding member 5 is the thickness of the floor board F as shown in FIG. Further, the holding member 5 is positioned at the insertion position. In addition, an annular packing P is placed on the floor surface of the floor plate F so as to be concentric with the through hole Fa. And the clamping member 5, the movable member 4, and the volt | bolt 3 of the attachment apparatus 1 are inserted in the through-hole Fa from the upper end opening part. At this time, since the thread surface of the screw hole 5c of the clamping member 5 is pressed against the thread surface of the screw portion 3a of the bolt 3 by the biasing force of the coil spring 6, the clamping member 5 is caused by the frictional resistance acting between them. Can be prevented from being inadvertently rotated from the insertion position to the clamping position before being inserted into the through hole Fa. Therefore, the clamping member 5 can be easily inserted into the through hole Fa.

  When the frame body 2 abuts against the floor surface of the floor board F via the packing P, the clamping member 5 passes through the through hole Fa downward. In this state, the bolt 3 is rotated in one direction so that the clamping member 5 moves upward. Then, the clamping member 5 rotates together with the bolt 3 due to the frictional resistance between the screw surface of the screw portion 3 a of the bolt 3 and the screw surface of the screw hole 5 c of the clamping member 5. When the clamping member 5 rotates from the insertion position to the clamping position, the outer peripheral surface of one side portion of the screw insertion portion 5b abuts against the locking projection 4b, thereby stopping at the clamping position. Therefore, when the bolt 3 is further rotated in one direction, the clamping member 5 moves upward as the bolt 3 rotates. And as shown in FIG. 10, the clamping member 5 cooperates with the frame 2, and clamps the floor board F. As shown in FIG. Thereby, the frame 2 is pressed and fixed to the floor surface of the floor board F via the packing P.

  Next, as shown in FIG. 11, the fixing screw B is inserted through the flange portion Gb formed in the main body portion Ga of the gas plug G and screwed into the screw hole 2e. Then, the main body Ga is fixed to the frame body 2 in a positioning state by tightening the fixing screw B. Thereafter, the cover Gc of the gas stopper G is fitted and fixed to the outer periphery of the frame body 2. Thereby, the attachment to the floor board F of the gas stopper G is completed.

  As described above, in the plug mounting device 1 according to the present invention, when the clamping member 5 is rotated together with the bolt 3 from the insertion position to the clamping position, the screw surface of the screw portion 3a of the bolt 3 and the screw hole of the clamping member 5 The frictional resistance between the screw surface of 5c is used. The frictional resistance between the screw surfaces is significantly larger than the frictional resistance between the outer peripheral surface of the bolt and the inner peripheral surface of the clamping member in the conventional stopper mounting device. Therefore, the clamping member 5 can be reliably rotated together with the bolt 3 from the insertion position to the clamping position. Therefore, the frame body 2 can be reliably fixed to the floor board F.

  Next, another embodiment of the present invention will be described. In the following embodiments, only the configuration different from the above-described embodiment will be described, and the same components are denoted by the same reference numerals and the description thereof will be omitted.

  12 to 23 show a second embodiment of the present invention. In the plug attachment device 1A of this embodiment, a movable member 4A is used instead of the movable member 4. The movable member 4 </ b> A is bent in a step shape at two locations slightly closer to the center side from both ends thereof, so that the intermediate portion is positioned below the sandwiching member 5. Locking projections 5d and 5e projecting downward are formed at both ends of the contact plate portion 5a of the clamping member 5. As shown in FIGS. 14 and 16, the holding position of the holding member 5 is determined by one locking projection 5d abutting against an intermediate portion located below the holding member 5 of the movable member 4A, and the other The locking projection 5e abuts against the intermediate portion of the movable member 4A, whereby the insertion position of the clamping member 5 is determined. Therefore, in this embodiment, the intermediate portion of the movable member 4A and the locking projection 5d constitute a rotation preventing mechanism for the clamping member 5. In this embodiment, the coil spring 6 is not provided, but the coil spring 6 may be provided.

  24 to 31 show a third embodiment of the present invention. In the plug attachment device 1B of this embodiment, a positioning member 7 that is a separate body from the frame 2 is used instead of the positioning protrusion 2c. One end of the positioning member 7 is fixed to the upper surface of the frame 2 by spot welding or the like. The other end portion of the positioning member 7 protrudes in the radial direction from the inner peripheral surface of the frame body 2, and a screw hole 7 a instead of the screw hole 2 e is formed at the other end portion. And the gas plug G is being fixed to the floor board F by screwing the bolt B penetrated by this screw hole 7a to the main-body part Ga of the gas plug G, and fastening.

  Further, in the plug attachment device 1B, a movable member 4B is used instead of the movable member 4. A pair of ring portions 4c and 4c are provided at one end of the movable member 4B. The pair of ring portions 4c, 4c are arranged apart from each other in the vertical direction (in the axial direction of the frame 2) by a distance substantially the same as or slightly longer than the thickness of the clamping member 5, and one side portion is connected to the connecting portion. Connected by 4d. A screw insertion part 5b of one clamping member 5 is inserted between the ring parts 4c, 4c. Therefore, when the clamping member 5 moves in the vertical direction, the screw insertion portion 5b hits the upper or lower ring portion 4c, and the movable member 4B moves reliably in the vertical direction together with the clamping member 5. Therefore, the coil spring 6 is unnecessary in the plug mounting device 1B. A connecting portion 4e that protrudes upward is provided at the other end of the movable member 4B, and a ring portion 4f is provided at the upper end of the connecting portion 4e. The ring portion 4 f is placed on the screw insertion portion 5 b of the other clamping member 5. A pair of ring portions 4f may be formed vertically, and the screw insertion portion 5b of the other holding member 5 may be inserted between the pair of ring portions 4f, 4f.

  The bolt 3 is rotatably and movably inserted into the ring portions 4 c and 4 c, and the bolt 3 is screwed into the screw hole 5 c of the screw insertion portion 5 b of one clamping member 5. Similarly, the bolt 3 is rotatably and movably inserted into the ring portion 4 f, and the bolt 3 is screwed into the screw hole 5 c of the screw insertion portion 5 b of the other holding member 5. Therefore, when the bolt 3 is rotated in a state where the rotation of the clamping member 5 is prevented, the movable member 4B and the clamping member 5 move in the vertical direction.

  As for one clamping member 5, the insertion position is determined by one side outer peripheral surface of the screw insertion portion 5b abutting one side portion of the connection portion 4d, and the other side outer peripheral surface of the screw insertion portion 5b is the connection portion. The clamping position is determined by abutting against the other side of 4d. As for the other clamping member 5, the insertion position is determined by the one side outer peripheral surface of the screw insertion portion 5b abutting one side portion of the connection portion 4e, and the other side outer peripheral surface of the screw insertion portion 5b is the connection portion. The clamping position is determined by abutting against the other side of 4e. Therefore, in this plug attachment device 1, the screw insertion portion 5b and the connecting portion 4d constitute a rotation prevention mechanism for one clamping member 5, and the screw insertion portion 5b and the connecting portion 4e rotate with respect to the other clamping member 5. A blocking mechanism is configured.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above embodiment, the frame body 2 is formed in a circular shape, but may be formed in other shapes such as an elliptical shape or a square shape as long as it is ring-shaped. In addition, the ring shape does not necessarily have to be continuous over the entire circumference, and a part of the frame body 2 may be cut out, for example, may have a substantially C shape.
In the above-described embodiment, the two clamping members 5 are both rotatable from the insertion position to the clamping position. However, one clamping member 5 may be fixed at the clamping position. Good. In that case, when the two clamping members 5 are inserted into the through holes Fa, the axis of the stopper mounting device 1 is shifted toward the clamping member 5 positioned at the clamping position with respect to the axis of the through holes Fa. The stopper mounting device 1 is positioned so that the two holding members 5 can be inserted into the through hole Fa. Then, after the two clamping members 5 have penetrated the through hole Fa, the axis of the stopper mounting device 1 is moved so as to coincide with the axis of the through hole Fa, so that the two clamping members 5 abut against the lower surface of the floor plate F. You can do that.
