  However, in the conventional panel support, the fixing means a on the floor surface caulks the base 3 a to the fixing member 2 and the adjustment bolt 3 is erected, and the mounting means c on the panel side also caulks the base 7 a to the receiving member 6. Since the adjustment bolt 7 is erected and assembled, there is a variation in the caulking according to the skill level of the operator, and there is a problem in the connection strength of the adjustment bolts 3 and 7 to the fixing member 2 and the receiving member 6. There was a problem of lack of accuracy. Furthermore, in the conventional panel support, since the material is a metal such as stainless steel, which has recently been rising in price, there has been a problem that the cost is significantly increased.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a panel support that increases the reliability by eliminating variations in assembling accuracy and drastically reduces costs.

Therefore, according to the first aspect of the present invention, for example, as shown in the embodiment shown below, the adjustment bolts 11 and 14 in which the male threads m and n are cut into the metal adjustment pipe 12 in which the internal threads w are cut in the inner peripheral surface. A panel support S which supports the panel P at a predetermined height position by adjusting a gap d opened between the floor surface F and the panel P by changing the screwing position. The adjustment bolts 11 and 14 are made of resin by insert molding with respect to a metal receiving member such as the support plate 13 that receives the panel P or a metal fixing member that is fixed to the floor surface F such as the support rose 10. Formed integrally into a cylindrical shape , male threads m and n are screwed on the peripheral surface portions of the cylindrical portions 20 and 25, and the enlarged diameter portions 20a and 25a are thickened by the height of the thread and the male screws are screwed. Don't install Flip amount corresponding with no mountains, characterized by comprising forming a thin-walled reduced diameter portion 20b · 25b in the circumferential direction.

According to a second aspect of the present invention, in the panel support S according to the first aspect, the adjustment pipe 12 has a plurality of engagements elongated in the axial direction on the inner peripheral surface, for example, as in the illustrated embodiment shown below. While the groove 12a is provided at intervals in the circumferential direction, the adjusting bolt 11 is provided with a hollow portion 19 that opens toward the free end at the center of the cylindrical portion 20, and the cylindrical portion 20 20, the male screw m is screwed on the outer peripheral surface, and pin guide portions such as a pair of pin insertion holes 21 that are conductive in the thickness direction are formed at diagonal positions, and a locking pin is provided in these pin guide portions. 30. These locking pins are urged radially outward by an urging spring 35 to hold the pin tip 30c so that it can protrude and retract from the pin guide portion.

According to the first aspect of the present invention, the panel support adjusting bolt is fixed to the receiving member of the panel or the floor surface by insert molding using an inexpensive resin material instead of the metal whose price has recently increased. Since the structure is formed integrally with the member, (1) the cost can be significantly reduced, and (2) the metal caulking process, which has a large proportion depending on the skill level of the operator, is omitted. Since the adjustment bolts are erected and assembled on the fixing member or the receiving member, the assembling accuracy can be eliminated and the reliability can be improved. In addition, according to the first aspect of the present invention, since the adjustment bolt has different thicknesses in the circumferential direction at the diameter-expanded portion and the diameter-reduced portion of the cylindrical portion, the adjustment bolt does not shrink in the process of cooling the resin immediately after the insert molding. Depending on the difference in the degree of shrinkage, the male screw is deformed at the diameter-expanded part that is slow to cool, and the male screw is formed into a loosening-preventing shape that includes uneven parts with uneven screw pitch. . Therefore, in the panel support according to the first aspect of the present invention, since the internal thread of the adjustment pipe and the external thread of the resin adjustment bolt having a partially uneven pitch are screwed together, (3) Even if an external force such as repeated impacts or vibrations due to repeated opening and closing of the door panel is received, the adjustment pipe side is affected by the elastic repulsive force of the male screw side of the resin adjustment bolt. A strong frictional bonding force is generated between the female screw and the screw and the screw can be locked so as not to loosen.

  According to the second aspect of the present invention, when adjusting the height of the gap from the floor surface by turning the adjustment pipe to change the screwing position, the locking pin is provided on the inner peripheral surface of the adjustment pipe with the female thread cut. While the adjustment pipe rotates while pushing the pin tip against the biasing spring against the biasing spring, the adjustment pipe rotates while the engagement groove reaches the angular position with the locking pin. The locking pin is pushed out by the urging force of the urging spring, the tip of the pin is once engaged with the engaging groove, and then the adjustment pipe is forcibly rotated against the urging spring, thereby preventing the locking pin. Is engaged with the next engagement groove, and each time the click feeling is sensed, the height adjustment operation can be performed with the click feeling as a guide, and the operability of the adjustment work can be improved accordingly. In addition, (2) external force is applied to the panel support, such as repeated impacts and vibrations, such as repeated opening and closing of the door panel, to loosen the adjustment bolt and the adjustment pipe. In the panel support of the present invention, the adjustment pipe is After turning to adjust the height of the gap from the floor surface, the locking pin is engaged with the engagement groove to lock the rotation of the adjustment pipe, so the adjustment bolt and adjustment pie are securely tightened without loosening over time can do.

  Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 11 shows a toilet door panel structure in a toilet booth to which a panel support as an example of the present invention is applied. In the door panel structure, a plurality of support panels P... Are arranged flush with each other and integrally connected by an upper headboard R, and each support panel P is connected to the floor surface F by the panel support S of the present invention. The gap d is adjusted and supported at a predetermined mounting height position, and the door panel D is rotatably attached to and supported by the support panel P on one side.

  As shown in FIG. 1, the panel support S of the present invention includes a fixing means A in which a base 11 a is connected to a support rose 10 of a fixing member fixed to a floor surface F, and an adjustment bolt 11 of a screw tool is erected, An adjusting pipe 12 of a fastener having an internal thread w cut on the inner peripheral surface, and a mounting means B in which a base portion 14a is connected to a support plate 13 of a receiving member that receives the support panel P, and an adjusting bolt 14 of the screw tool is erected. , And locking means C attached to the adjusting bolt 11 of the fixing means A.

  In the fixing means A, the support rose 10 is made of a metal, for example, stainless steel, in a disc shape, and provided with a mounting hole 15 into which the base 11a of the adjusting bolt 11 is fitted at the center, while the peripheral edge 10a is bent downward and reversed. Shaped in a dish shape. The mounting hole 15 is not a perfect hole, but is formed with a non-circular detent hole, for example, a hexagonal hole as shown in FIG.

  Therefore, as shown in FIG. 3, the fixing means A integrally molds the adjusting bolt 11 with the support rose 10 with resin by insert molding. The adjustment bolt 11 is provided with a hollow hole 19 that opens toward the free end in the center, and is erected in a cylindrical shape. The cylindrical portion 20 is provided with a male screw m at a symmetrical peripheral surface portion. Then, while forming a pair of enlarged diameter portions 20a that are thicker than the height of the thread, a male screw is not screwed on the symmetrical peripheral surface portion between the enlarged diameter portions 20a, and the thickness is reduced as much as there is no thread. A pair of reduced diameter portions 20b having a concave shape is formed into a loosening prevention shape. In particular, as shown in FIG. 1, the cylindrical portion 20 is provided with pin insertion holes 21 penetrating in the thickness direction as pin guide portions at symmetrical positions of the reduced diameter portion 20b. In place of the pin insertion hole 21 shown in the figure, a pin guide groove that conducts in the thickness direction may be formed in a diagonal position at the upper end portion of the cylindrical portion 20 to form a pin guide portion.

  Now, since the adjustment bolt 11 of the fixing means A has a different thickness in the circumferential direction in the enlarged diameter portion 20a and the reduced diameter portion 20b of the cylindrical portion 20, there is a difference in the degree of shrinkage in the process of resin cooling immediately after insert molding. The male screw m is deformed at the diameter-expanded portion 20a that is slow to cool based on the difference in the degree of contraction, and the male screw m is formed in a loosening prevention shape including a portion where the screw pitch is not uniform due to strain. In addition, in the fixing means A, the adjustment bolt 11 is molded in a locking state in which the base 11a is fitted into the hexagonal mounting hole 15 of the support rose 10 to be integrated during insert resin molding. In the present invention, the fixing means A has a symmetrical shape with the enlarged bolt portion 20a in which the cylindrical portion 20 is screwed with the male screw m and the concave reduced-diameter portion 20b in which the adjusting bolt 11 is not threaded. After the insert molding is integrally performed with the metal support rose 10 and the resin, there is an advantage that the mold can be easily and quickly released without trouble by simply dividing the mold into two in the opposite direction.

  On the other hand, in the attachment means B, the support plate 13 is made of a narrow metal plate such as a stainless steel plate corresponding to the thickness of the support panel P, and the base portion 14a of the adjusting bolt 14 is fitted in the middle in the length direction. A mounting hole 16 is provided. The mounting hole 16 is formed in two stages by drilling one side of the plate thickness direction in a non-rotating anti-rotation hole, for example, a hexagonal hole shown in FIG. 4, and drilling the other side receiving the support panel P in a round hole. Forming.

  Therefore, in the mounting means B as well, as shown in FIG. 5, the adjusting bolt 14 is formed integrally with the support plate 13 by resin by insert molding. The adjustment bolt 14 is provided with a hollow hole 24 that opens toward the free end at the center and is erected in a cylindrical shape. The cylindrical portion 25 is provided with a male screw n at a symmetrical peripheral surface portion. Thus, a pair of enlarged diameter portions 25a that are thicker than the height of the thread are formed, while a male screw is not screwed on the symmetrical peripheral surface portion between the enlarged diameter portions 25a, and the thickness is reduced as much as there is no thread. It shape | molds in the shape which formed a pair of diameter-reduced part 25b which became concave.

  Therefore, the adjusting bolt 14 also has a thickness difference in the circumferential direction between the diameter-enlarged portion 25a and the diameter-reduced portion 25b of the cylindrical portion 25 even in the attachment means B. Based on the difference in the degree of contraction, the male screw n is deformed in the diameter-expanded portion 25a that is slow to cool, and the male screw n is formed in a loosening prevention shape including a portion where the screw pitch is not uniform due to strain. In addition, in the attachment means B, the adjustment bolt 14 is molded in the lock-locked state with the base portion 14a fitted and integrated into the hexagonal mounting hole 16 of the support plate 13 at the time of insert resin molding. In the present invention, the attachment means B also has a symmetrical shape between the enlarged bolt portion 25a in which the cylindrical portion 25 is screwed with the male screw n and the concave reduced-diameter portion 25b in which the adjusting bolt 14 is not provided. After the insert is integrally molded with the metal support plate 13 and the resin, there is an advantage that the mold can be easily and quickly released without trouble by simply dividing the mold into two in the opposite direction.

  On the other hand, the adjustment pipe 12 is made of metal and is formed into a tubular shape by extrusion molding of aluminum in the illustrated example. As shown in FIG. 1, the female screw w on the inner peripheral surface has a threaded portion on one side in the length direction and an adjustment bolt 11. In accordance with the screw direction of the male screw m in the enlarged diameter portion 20a, for example, a left screw is formed. On the other hand, the screw portion on the other side is matched with the screw direction of the male screw n in the enlarged diameter portion 25a of the adjustment bolt 14, for example, right It is formed with screws. In addition, the adjustment pipe is formed by, in particular, engraving a plurality of engaging grooves 12a elongated in the axial direction on the inner peripheral surface of the female screw w cut at intervals in the circumferential direction. In the illustrated adjustment pipe 12, the engagement groove 12 a is recessed in a V-shaped cross section, and corresponds to a pair of pin insertion holes 21 provided in the adjustment bolt 11, with a 45 degree interval in the circumferential direction at a diagonal position on the inner peripheral surface. Two pairs are cut at equal intervals with a gap.

  The locking means C includes a pair of locking pins 30 and an urging spring 35 of an elongated compression coil spring. As shown in FIG. 6, the locking pin 30 is provided with a retaining step portion 30 a with a diameter that is enlarged by one step at the base end, and a spring insertion hole 30 b is formed in the axial direction from the end surface of the retaining step portion 30 a. On the other hand, the pin tip 30c is tapered. This loosening prevention means C inserts the loosening prevention pin 30 into the lightening hole 19 of the adjusting bolt 11 with both ends of the urging spring 35 fitted into the spring fitting hole 30b, and then the hole edge of the pin insertion hole 21. The locking pin 30 is fitted into the pin insertion hole 21 in a retaining state where the retaining step portion 30a hits the pin, and the locking pin 30 is urged radially outward by a biasing spring 35 to pin the tip 30c. Is assembled in such a manner that it can be freely projected and retracted from the pin insertion hole 21.

  Therefore, the panel support S having the above-described component configuration is configured such that the male screw m of the adjusting bolt 11 is screwed to one side of the female screw w of the adjusting pipe 12 and the male screw n of the adjusting bolt 14 is screwed to the other side. The fixing means A and the attaching means B are connected and assembled by the adjusting pipe 12. Then, by changing the screwing position of the adjustment pipe 12, the fixing means A and the attachment means B are expanded and contracted so as to be adjustable in height. Further, in the illustrated panel support S, when the adjustment pipe 12 is turned to adjust the height by changing the screwing position, as shown in FIG. 7A, the adjustment pipe 12 is loosened on the inner peripheral surface of the female pipe w cut off. The adjustment pipe 12 rotates while pressing the stop pin 30 and pushing the pin tip 30c against the urging spring 35 into the pin insertion hole 21, while the engagement groove 12a is loosened to stop the pin. When the angle position of 30 is reached, as shown in FIG. 5B, the locking pin 30 is pushed out by the urging force of the urging spring 35 and the pin tip 30c is once engaged with the engaging groove 12a, and then Further, the adjustment pipe 12 is forcibly rotated against the urging spring 35, so that the locking pin 30 is engaged with the next engagement groove 12a. It can be adjusted height omissions. Therefore, when the panel support S is adjusted to the desired height by turning the adjustment pipe 12 as described above, when the rotation of the adjustment pipe 12 is stopped by engaging the locking pin 30 with the engagement groove 12a, the bias spring As long as the adjustment pipe 12 is not forcibly turned against 35, the structure is designed to prevent the adjustment pipe 12 from rotating further.

  When the support panel P is erected with the panel support S configured as described above, the support plate 13 of the mounting means B is screwed to the lower end surface of the support panel P, and the panel support S is attached to the support panel P. Assemble. Thereafter, the support panel P is lifted and the upper end of the panel is assembled to the headboard R and suspended. Then, while appropriately adjusting the adjustment pipe 12 or the fixing means A with respect to the fixing means B in the fixed state, the length of the panel support S is adjusted in accordance with the gap d with the floor surface F, and the support rose 10 is fixed to the floor. After pressing against the surface F, it is screwed to the floor surface F as shown in FIGS. 8 and 9, and the support panel P is received and supported by the panel support S from below. In this case, if the mounting height position of the support panel P is not accurate, the adjustment pipe 12 or the fixing means A is rotated, and the panel support S is expanded and contracted vertically as shown in FIGS. 10 (A) and 10 (B). Thus, the gap heights d1 and d2 between the support panel P and the floor surface F are adjusted, and the support panel P is positioned and supported at a predetermined mounting height position.

  In particular, in the illustrated panel support S, as shown in FIG. 7A, when the adjustment pipe 12 is forcibly turned against the biasing spring 35, the pin tip 30c of the locking pin 30 is rotated during the rotation. Each time is engaged with the engaging groove 12a, the user feels the click feeling and adjusts the click feeling to a desired height. Therefore, after the panel support S has finished adjusting the desired height by rotating the adjustment pipe 12 as described above, as shown in FIG. The rotation of the adjusting pipe 12 is locked by engaging.

  By the way, in the door panel structure of the toilet booth, the panel support S receives external force to loosen the screwing of the adjusting bolts 11 and 14 and the adjusting pipe 12 such as repeated impact and vibration by opening and closing the door panel D. . However, in the panel support S of the present invention, even if such an external force is applied over time, the internal thread w of the adjustment pipe 12 and the external thread m · of the resin adjustment bolts 11 and 14 whose thread pitches are partially uneven. Since n is screwed into a screw fastening state, a strong frictional joining force is generated between the female screw 4 on the adjustment pipe 12 side due to the elastic repulsion force on the male screw m · n side of the resin adjustment bolts 11 and 14, This frictional joining force can be locked so that the screw fastening state is not loosened.

  At the same time, in the illustrated panel support S, as shown in FIG. 7B, the locking pin 30 engages with the engagement groove 12a to stop the rotation of the adjustment pipe 12, and this also prevents the screw fastening state from loosening. By locking in this manner, it is possible to secure the locking.

  In addition, in the illustrated panel support S, the adjustment bolts 11 and 14 are integrally formed with the base portions 11a and 14a being fitted into the hexagon mounting holes 15 and 16 of the support rose 10 and the support plate 13 in a non-rotating state, respectively. Even if an external force is applied to loosen the screw by rotating the adjusting bolts 11, 14 such as impact or vibration over time, the adjusting bolts 11, 14 rotate with respect to the support rose 10 and the support plate 13 and come off. Since it is formed in a locked state so that it does not occur, this can further promote the effect of preventing the screws from loosening.

  Incidentally, the panel support S of the illustrated example has a locking structure in which the pin insertion hole 21 into which the locking pin 30 is fitted is provided in the cylindrical portion 20 of the fixing means side adjustment bolt 11. Instead, for example, a loosening prevention structure in which a pin insertion hole for fitting a locking pin is provided in the cylindrical portion 25 of the attachment means side adjusting bolt 14 or a locking pin is fitted in both cylindrical portions. It is also possible to provide a locking structure provided with a pin insertion hole.

  Further, the above-described panel support S has a structure in which the adjustment bolt 14 of the attachment means B and the adjustment bolt 11 of the fixing means A are screwed and connected to the upper and lower ends of the adjustment pipe 12 so that they can be expanded and contracted. The present invention is not limited to this, and may have a structure in which an adjustment pipe is erected on the fixing means side, and an adjustment bolt on the attachment means side is screwed to the upper end side of the pipe so that it can be expanded and contracted. Further, a structure in which an adjustment pipe is erected on the attachment means side, and an adjustment bolt on the fixing means side is screwed to the lower end side of the pipe, and is similarly connected so as to be extendable and contractible.
