Description

  The present invention relates to a faucet mounting structure, and more particularly to a faucet mounting structure for mounting a faucet body at a position higher than a faucet mounting plate portion.

  Conventionally, as a method of attaching the faucet body to the faucet mounting plate part, it has a diameter corresponding to the size of the through hole provided in the faucet mounting plate part and penetrates the through hole and screwed into the faucet body. A so-called lock nut system that uses a substantially cylindrical mounting screw tube and a tightening nut that is screwed into the mounting screw tube from the bottom of the faucet mounting portion, and is fixed by tightening the mounting screw tube and the tightening nut. The faucet mounting structure is considered.

  The faucet mounting includes a bolt that is attached to the lower end of the faucet body so as to pass through a through-hole formed in the faucet mounting plate, and an insertion hole configured to allow the bolt to pass therethrough. It has a horseshoe-shaped washer arranged on the lower surface of the plate part and a nut that is screwed into a bolt that is inserted through the insertion hole of the washer and tightened. A so-called horseshoe-type faucet attachment structure for attaching the stopper body to the faucet attachment plate portion is also considered.

  The horseshoe method can not only easily perform the mounting work compared to the lock nut method, but also forms a cheaper bolt longer than the mounting screw tube even when the faucet mounting plate is thick. This is preferable because the manufacturing cost can be kept low, and the size and shape of the through hole provided in the faucet mounting plate can be flexibly dealt with. However, there is a problem that it is somewhat weak against the force applied in the lateral direction as compared with the lock nut method.

  On the other hand, in recent years, so-called toll type faucets have been used in which the faucet body is arranged at a higher position than the faucet mounting plate in accordance with the peripheral design of the faucet body. It is considered to connect extension tubes having shapes. However, it has been difficult to adopt a horseshoe system for a faucet mounting structure of a toll type faucet. In other words, when the faucet is a toll type, it is necessary to extend the bolt according to the height extension. However, the longer the bolt is, the more stress is applied to the bolt when lateral stress is applied. Inevitably increases, resulting in product instability.

  For this reason, in the following Patent Document 1, it is shown that a lock nut method is adopted as a faucet mounting structure of a toll type faucet. That is, as shown in FIG. 10, when attaching the faucet body 94 of the faucet 93 to the upper end of the attachment screw pipe 92 fixed to the basin 91 via the tightening nut 90, the upper end of the attachment screw pipe 92. It has been proposed that an extension cylinder 95 formed separately is interposed between the lower end of the faucet body 2 and the height of the faucet body 93 is set high.

JP-A-6-212671

  However, in the configuration as shown in Patent Document 1, since it is a lock nut type faucet mounting structure, the construction is not only complicated, but also the extension cylinder 95 using a relatively expensive mounting screw tube 92. There is a problem that the construction cost is raised. In addition, the diameter of the attachment screw tube 92 needs to be precisely matched to the diameter of the through hole provided in the faucet attachment plate portion, and there is a problem that the versatility is lacking.

  On the other hand, in the case of a toll type faucet, in order to stably join the extension cylinder 95 to the faucet body 94, it is preferable to screw the extension cylinder 95 to the faucet body 94. Since it is difficult to stably position the rotational position in the joined state, it is difficult to connect the bolt directly to the extension cylinder 95 and attach it to the faucet mounting plate portion by the horseshoe method. That is, it has been difficult to fix the tall-type faucet by the horseshoe-type faucet mounting structure.

  The present invention has been made in consideration of the above-mentioned matters. The purpose of the present invention is to provide a water faucet body that can be stably mounted at a position higher than the faucet mounting plate portion and that is easy to mount. It is an object to provide a stopper mounting structure.

  In order to solve the above-mentioned problem, the first invention is a bolt that is connected to the faucet body at the lower part of the faucet body and hangs down so as to pass through a through hole formed in the faucet mounting plate, and this bolt can be inserted. A washer that is provided on the lower surface of the faucet mounting plate portion and a nut that is screwed into a bolt that is inserted through the insertion hole of the washer and tightened. A faucet mounting structure for holding the faucet mounting plate portion and attaching the faucet body to the faucet mounting plate portion, an extension cylinder extending to the lower end of the faucet body, and an inner peripheral surface of the extension cylinder And an insertion hole for inserting the bolt and an insertion hole for inserting a water supply pipe, respectively, and a support column standing on the faucet mounting plate in the tightened state by the bolt and nut. Enough to keep the installation state stable Providing faucet mounting structure and having a substantially cylindrical pillar blocks of the (claim 1).

  According to the faucet mounting structure having the above-described configuration, the strut block is rotatable in the extension cylinder in a state in which the strut block is inserted into the extension cylinder and the extension cylinder is extended to the lower end of the faucet body. The column block and the faucet body can be easily aligned. In addition, by tightening the nut to the bolt, tension is applied to the bolt, and the standing state of the column block provided with the insertion hole into which the bolt is fitted can be stabilized, and the extension cylinder into which the column block is inserted is erected. The state can be stabilized. That is, attachment can be easily performed basically in the same manner as the horseshoe system, and the attachment state can be stabilized.

  The bolt is fixed to a fitting hole formed in a lower end portion of the support block by screwing, welding, or adhesion, and the support block is retained at the lower end portion of the extension cylinder, and the extension cylinder is a faucet It is preferable that the lower end of the main body is screwed. That is, it is preferable that the bolt is connected to the faucet body via a support block disposed at the lower part of the faucet body and an extension cylinder for retaining the support block.

  In this case, when the bolt and the nut are tightened, the tension applied to the bolt acts on the faucet body via the support block and the extension cylinder, so that the faucet body can be firmly attached to the faucet mounting plate. In addition, since the bolt can be formed short, the strut block can be stably fixed at a position close to the faucet mounting plate (and nut) by tightening the bolt and nut, and resists lateral force. Possible stable installation can be performed.

  However, the bolt may be connected to the lower end of the faucet body by being screwed directly. In this case, it is necessary to form the bolt longer by the length of the extension cylinder, but this bolt penetrates the insertion hole formed in the column block, and in the tightened state by the bolt and nut, this tension is applied by the tension applied to the bolt. The position of the insertion hole through which the bolt penetrates can be fixed to stabilize the posture of the column block, and the column block can fix the lateral position of the bolt in the extension cylinder at a position near the nut. . That is, stable attachment can be performed while resisting lateral force. In this case, the extension cylinder can be attached to the faucet body by fitting, and can be easily constructed as compared with the case where the extension cylinder is screwed.

  The second invention includes a bolt that is connected to the faucet body at a lower portion of the faucet body and hangs down so as to pass through a through hole formed in the faucet mounting plate portion, and an insertion hole configured to allow insertion of the bolt. A washer disposed on the lower surface of the faucet mounting plate portion, and a nut that is screwed into a bolt inserted through the insertion hole of the washer and tightened, and the faucet mounting plate portion is sandwiched by tightening the nut. And a faucet mounting structure for attaching the faucet body to the faucet mounting plate part, an extension cylinder screwed to the lower end of the faucet body, an outer peripheral surface in contact with the inner peripheral surface of the extension cylinder, and water A strut block that has an insertion hole through which the water supply pipe of the stopper main body is inserted and is rotatably inserted into the extension cylinder and to which the bolt is connected, and a hole formed in the upper surface of the strut block and the lower surface of the faucet body Fit the both ends to the support block against the faucet body. And the column block is a column that is erected on the faucet mounting plate in a tightened state with bolts and nuts, thereby stabilizing the standing state of the extension cylinder. A faucet mounting structure characterized by having a height that can be held is provided.

  According to the faucet mounting structure having the above-described configuration, a faucet block is inserted into the extension cylinder, and the faucet is inserted with both ends of the metal core inserted into holes formed in the upper surface of the strut block and the lower surface of the faucet body. An extension cylinder can be screwed to the lower end of the main body. At this time, since the strut block is rotatable in the extension cylinder, the position of the strut block and the faucet body in the rotational direction does not shift, and the water supply pipe inserted through the insertion hole provided in the strut block is twisted. Power is not added. Also, by tightening the nut on the bolt, tension is applied to the bolt and downward force can be applied to the column block, so that the standing state of the column block can be stabilized and this column block is inserted as much as it is. It is possible to stabilize the standing state of the extended cylinder.

  The bolt is connected to the support block by being fixed by being screwed, welded, or adhered to a hole formed in the lower end of the support block, and the support block is retained at the lower end portion of the extension cylinder. The extension tube is preferably screwed to the lower end of the faucet body. That is, it is preferable that the bolt is connected to the faucet body via a support block disposed at the lower part of the faucet body and an extension cylinder for retaining the support block. It should be noted that the deeper the hole of the support block for fitting the bolt, the stronger the tightening with the bolt and nut.

  In this case, when the bolt and the nut are tightened, the tension applied to the bolt acts on the faucet body via the support block and the extension cylinder, so that the faucet body can be firmly attached to the faucet mounting plate. In addition, since the bolt can be formed short, the strut block can be stably fixed at a position close to the faucet mounting plate (and nut) by tightening the bolt and nut, and resists lateral force. Possible stable installation can be performed.

  On the other hand, the core metal is a rod-shaped member having a strength that can fix the positional relationship between the support block and the faucet body, and the upper end of the metal core is threaded, welded, bonded, or interference-fitted. It may be fitted so as to be firmly connected to the stopper body. Similarly, the lower end of the metal core may be tightly fitted to the support block by an interference fit or adhesion or screwing. In this case, since the position of the faucet body and the support block can be completely fixed by the cored bar, the bolt is connected to the faucet body through the cored bar and the support block, and more Robust.

  When the extension cylinder is provided with a step portion that contacts the lower end portion of the support block (Claim 3), the step portion serves as a retaining member that retains and retains the support block, so that by tightening the bolt and nut, The tension applied to the bolt is reliably applied to the extension cylinder via the support block, and the faucet body can be attached to the faucet mounting plate portion more firmly via this extension cylinder.

  In this case, the cored bar prevents the positional displacement of the support block and the faucet body in the rotational direction. For example, both ends are fitted into holes formed in the upper surface of the support block and the lower surface of the faucet body. To be fitted. That is, when the extension tube is screwed into the faucet body, the misalignment in the rotational direction can be fixed by simply inserting the core metal into the hole, and when the extension tube is screwed and connected to the faucet body The water supply pipe is not damaged without the support block rotating. In addition, the depth of both holes should just be the depth which can fix the position shift of the support | pillar block when attaching an extension cylinder to a faucet main body, and attaching to an attachment board.

The third invention comprises a bolt that is connected to the faucet body at the lower part of the faucet body and hangs down so as to pass through a through-hole formed in the faucet mounting plate portion, and an insertion hole configured to allow insertion of the bolt. A washer disposed on the lower surface of the faucet mounting plate portion, and a nut that is screwed into a bolt inserted through the insertion hole of the washer and tightened, and the faucet mounting plate portion is sandwiched by tightening the nut. A faucet mounting structure for attaching the faucet body to the faucet mounting plate part,
An extension cylinder extending to the lower end of the faucet body, and a support block that is inserted into the extension cylinder and retained by a step formed at the bottom of the extension cylinder, and the support block A water faucet mounting structure is provided in which the bolt is fixed to a lower end of the water faucet (claim 4).

  According to the faucet mounting structure having the above-described configuration, the extension cylinder can be screwed and connected to the lower end portion of the faucet body with the support block inserted in the extension cylinder. At this time, since the support block inserted into the cylindrical extension cylinder is rotatable within the extension cylinder, the position of the support block and the faucet body in the rotational direction can be prevented from shifting. Further, by tightening the nut to the bolt, tension is applied to the bolt and a downward force can be applied to the support block, so that the extension cylinder can be stably fixed in an upright state via the stepped portion.

  It is preferable that an insertion hole into which a bolt is inserted is formed at a lower end portion of the support block, and the bolt is screwed, welded, or bonded to the insertion hole. In other words, the bolt is connected to the faucet body via a support block disposed at the lower part of the faucet body and an extension cylinder for retaining the support block.

  The bolt is fixed to the support block at the position closest to the lower end of the support block, that is, the nut, so that the stability of the bolt and nut in the tightened state is improved and stable to resist lateral force. A faucet can be attached.

  When the step portion is a split ring that fits into an annular groove formed on the inner peripheral surface of the extension cylinder (Claim 5), the groove is easily formed by cutting the inner peripheral surface of the extension cylinder. By fitting the split ring into this groove, a step portion for retaining and holding the column block can be formed. Further, since the split ring can be fitted into the groove in a state where the support block is inserted from the lower end of the extension cylinder attached to the faucet body, the faucet can be easily attached. In addition, by removing the split ring from the groove, the support block can be removed from the lower end of the extension cylinder, and maintenance is facilitated.

  A sensor for detecting a user's hand is attached to the faucet body, and a flat plate portion interposed between the support block and the faucet mounting plate portion and a signal line hanging from the flat plate portion and connected to the sensor are inserted. In the case of having a wiring protection member having a wiring protection cylinder to be used (Claim 6), since the signal line of the automatic faucet can be protected by a washer etc. during installation, it can be protected by the wiring protection cylinder. Is easy and reliability is improved.

  As described above, according to the present invention, the extension tube can be connected to the lower end portion of the faucet body to adjust the height of the faucet, and can be easily and firmly attached to the through hole. Attachment is easy by attaching the faucet body to the through hole using bolts, washers and nuts. In addition, a support block is inserted into the extension cylinder extended to the attached faucet body, and this support block stably holds the standing state when the bolt and nut are tightened. The installation state can be stably maintained.

  Next, the attachment method of the faucet body 2 using the faucet attachment structure 1 having the above-described configuration will be described with reference to FIG.

  That is, the support block 11 is inserted into the extension cylinder 10, the water supply pipe 21 is inserted into the insertion hole 11c formed in the support block 11, the signal line 26 is inserted into the insertion hole 11d, and the insertion hole formed in the flat plate portion 14a. The water supply pipe 21 and the bolt 13 are inserted into 14c, and the signal line 26 is inserted into the wiring protection cylinder 14b, and the water supply pipe 21, the bolt 13, and the wiring protection cylinder 14b are inserted into the faucet with the packing 17 interposed therebetween. It is inserted into the through hole 3 a of the mounting plate portion 3.

  On the other hand, a water supply pipe 21 is screwed and connected to a water supply port 2d provided at the lower end portion of the faucet body 2 so that the water supply pipe 21 and the water flow path 22 are connected in communication, and the upper and lower ends of the metal core 12 are connected to the holes 2a and 11a. In a state where the portions are fitted, the male screw portion 10a formed at the upper end of the extension tube 10 is rotated as indicated by an arrow A, and is screwed and connected to the female screw portion 2c provided at the lower end portion of the faucet body 2. At this time, the support block 11 is rotatably inserted into the extension cylinder 10. In a state where the position of the support block 11 and the extension cylinder 10 in the rotation direction is fixed, only the extension cylinder 10 can be rotated in the direction of arrow A, and this can be firmly connected to the faucet body 2.

  Next, the packing 18 and the washer 15 are arranged so that the bolt 13 protruding from the lower surface of the through hole 3a is inserted, and the nut 16 is fastened to the bolt 13 protruding downward from the insertion hole 15a. At this time, the washer 15 and the column block 11 are pulled toward each other by tightening the bolt 13 and the nut 16, thereby sandwiching the step portion 10 b provided at the lower end portion of the extension cylinder 10, the wiring protection member 14, and the packings 17 and 18. In this state, the faucet mounting plate portion 3 can be pinched. In other words, the column block 11 can be firmly maintained in the standing state by tightening the bolt 13 and the nut 16 and at the same time, sandwiching the step portion 10b of the extension cylinder 10, so that a force for pulling the extension cylinder 10 downward is applied. be able to.

  Since the washer 15 has a substantially C-shaped horseshoe shape, the washer 15 does not need to be inserted through the water supply pipe 21 and the wiring protection cylinder, and the construction is easy. Further, if the length of the bolt 13 is increased, it is possible to sufficiently cope with the difference in the thickness of the faucet mounting plate portion 3. In addition, since the curved portion 15c is formed in the washer 15, the washer 15 has a three-dimensional shape and can withstand the tightening stress. Further, the size of the through hole 3a formed in the faucet mounting plate 3 is such that the water supply pipe 21, the bolt 13 and the wiring protection member 14b can be inserted, and the area is smaller than the horizontal sectional area of the extension cylinder 10. It is what has.

  Further, since the signal line 26 is inserted through the wiring protection cylinder 14b, the washer 15 does not hit the signal line 26 and damage it, so that the reliability of the faucet body 2 can be kept high and the mounting work is facilitated. It can be carried out.

  Tighten the bolt 13 by tightening the nut 16 to the bolt 13 to tighten the space between the support block 11 and the washer 15, and apply a downward force to the stepped portion 10b, the flat plate portion 14a, and the packing 18 in a sandwiched state. In addition, the faucet mounting plate portion 3 can be held. At this time, since the column block 11 is for fixing a bolt to the lower end portion thereof, the column block 11 is firmly fixed so as to be in a standing state at a position P close to the nut 16 by tightening with the bolt 13 and the nut 16. be able to. At the same time, a step portion 10b provided at the lower end of the extension cylinder 10 is pressed downward by the support block 11, and the outer peripheral surface of the support block 11 is in contact with the inner peripheral surface of the extension cylinder 10. Can be fixed in the standing state, and the standing state of the faucet body 2 screwed and connected to the extension cylinder 10 can be stabilized.

  In addition, the height H of the column block 11 is a column that is erected on the faucet mounting plate 3 in the tightened state with the bolt 13 and the nut 16, so that the standing state of the extension cylinder 10 can be stably maintained. Therefore, the standing state can be maintained by resisting the stress applied to the faucet body 2 in the lateral direction. In addition, the standing state of the extension cylinder 10 can be stably held, so that the height H of the support | pillar block 11 becomes high. Moreover, since the both ends of the metal core 12 are fitted into the holes of the faucet body 2 and the support block 11, the positional relationship in the rotational direction of the faucet body 2 and the support block 11 is fixed. It is possible to more strongly resist the stress applied to the main body 2.

  FIG. 7 is a view showing a modification of the faucet mounting structure 1. As shown in FIG. 7, a male screw portion 12a is formed at the upper end of the core metal 12 to be screwed into a female screw hole 2e formed at the lower end of the faucet body 2, and the hole 11a is formed at the lower end portion of the core metal 12. A female screw portion 12b is formed to which a screw B provided through the bottom surface of the hole 11a is attached. By comprising in this way, the upper-lower-end part of the metal core 12 can be fixed to the faucet main body 2 and the support | pillar block 11, and robustness improves further.

  The attachment portion of the core metal 12 to the faucet body 2 may be welded or adhesive, or may be an interference fit. Moreover, the attachment part of the metal core 12 with respect to the support | pillar block 11 may use an interference fit or an adhesive agent.

  FIG. 8 is a view showing a configuration of a faucet mounting structure 30 according to the second embodiment of the present invention. The faucet mounting structure 30 shown in FIG. 8 is different from the faucet mounting structure 1 shown in FIGS. 1 to 7 in that a female screw hole 2e provided at the lower end of the faucet body 2 at the upper end instead of the bolt 13 is used. And a through hole 11f that contacts the support block 11 with the outer peripheral portion of the bolt 31. And a small-diameter portion 10c that is fitted into a recess provided in the lower end portion of the faucet body 2 at the upper end portion of the extension cylinder 10 is formed.

  According to the faucet mounting structure 30 having the above-described configuration, the male screw 31 b at the upper end of the bolt 31 is directly screwed and connected to the faucet body 2, so that the bolt 31 and the nut 16 are tightened so Thus, the faucet body 2 can be attached to the faucet mounting plate portion 3 by being pressed against the faucet mounting plate portion 3 with the extension cylinder 10, the flat plate portion 14 and the packing 17 interposed therebetween. Further, since the bolt 31 is fitted so as to be in contact with the inside of the insertion hole 11f of the support block 11 at an intermediate portion thereof, the tension applied to the bolt 31 is increased as the bolt 31 and the nut 16 are tightened. It can be stably held in the standing state, and the position of the bolt 31 in the extension cylinder 10 can be fixed.

  That is, since the standing state of the extension cylinder 10 is stabilized by the support block 11, the tall type faucet can be attached by a so-called horseshoe system. It should be noted that serrations may be formed at the joint between the extension tube 10 and the faucet body 2 so as to suppress displacement in the rotational direction of the faucet body 2 and the extension tube 10. In addition, it is possible to perform the same modification as that of the first embodiment shown in FIGS.

  FIG. 9 is a view showing a configuration of a faucet mounting structure 40 according to the third embodiment of the present invention. The faucet attachment structure 40 shown in FIG. 9 is different from the faucet attachment structures 1 and 30 shown in FIGS. 1 to 8 in that it is formed in an annular shape formed by cutting the inner peripheral surface of the lower end portion of the extension cylinder 10. And a retaining ring 41 made of a split ring fitted in the groove 10d. The groove 10d prevents the downward movement with the retaining ring 41 fitted. The retaining ring 41 abuts the lower end portion of the support block 11 to hold the support block 11 on the extension cylinder 10.

  According to the faucet mounting structure 40 of the third embodiment, after connecting the water supply pipe 21 to the faucet body 2 and screwing and connecting the extension cylinder 10 to the faucet body 2, the support block is formed from the lower end of the extension cylinder 10. 11 is inserted, and the split ring 41 is fitted into the groove 10d, so that the column block 11 can be prevented from being pulled out, and the faucet can be easily attached. In addition, by removing the split ring 41 fitted in the groove 10d, the support block 11 can be pulled out from the lower end of the extension cylinder 10, and maintenance can be facilitated.
