Description

  The present invention relates to an attachment structure for attaching an article such as a faucet to an attachment base such as a counter, and more particularly to an article for attaching and fixing an article such as a faucet to an attachment base from the attachment surface side using an adapter device. .

As an attachment structure for attaching a predetermined article, for example, a water faucet, to the attachment surface of the attachment base, for example, the upper surface of the counter, the attachment structure shown in FIG. 21 has been conventionally employed.
In this mounting structure, the male threaded tube 202 provided in the faucet 200 is inserted into the faucet mounting hole 206 formed in the counter 204 from the mounting surface, that is, the upper surface side, and the fixing nut 208 is inserted from the back surface side of the counter 204. Is attached to the male screw tube 202 and the faucet 200 is attached.

  However, in the case of this mounting structure, the fixing nut 208 must be fitted and tightened from the back side of the counter 204. Therefore, the mounting workability of the faucet 200 is poor, and much labor is required for the mounting work. There was a problem that took.

  As a solution to this problem, it is considered that an adapter device is attached to a counter and a faucet is attached to the counter via the adapter device.

FIG. 22 shows an example of a conventionally known faucet mounting structure using the adapter device (disclosed in Patent Document 1 below).
In the figure, reference numeral 210 denotes an adapter device, which includes an adapter main body 212, a pair of holders 214, and a number (two) of male screw members 216 corresponding to the holders 214.

  In the case of this mounting structure, the corresponding male screw members 216 are screwed into the respective female screw holes 218 of the pair of holders 214, and the pair of holders 214 are rotated inward from each other, that is, toward the center of the mounting hole 206. In this state, the holders 214 are inserted into the faucet mounting holes 206 from the upper surface side of the counter 204.

  Then, the pair of holders 214 are rotated outward from each other on the back side of the counter 204 so that each of the pair of holders 214 is brought into contact with the back surface of the counter 204, and in this state, the pair of male screw members 216 are placed on the upper side of the counter 204. The adapter body 210 is attached to the counter 204 so that the adapter main body 212 and the holder 214 squeeze the counter 204 from both the front and back surfaces.

  Thereafter, the lower end portion of the faucet 200 is externally fitted to the adapter main body 212, and the faucet 200 is fixed to the adapter main body 212 with a stopper, so that the faucet 200 is attached and fixed to the counter 204.

  This faucet attachment structure has an advantage that the adapter device 210 and the faucet 200 can be attached and fixed to the attachment surface of the counter 204 from the upper surface side of the counter 204.

However, in the case of this faucet mounting structure, each of the pair of holders 214 is screwed to the adapter main body 212 with one male screw member 216, so that it is within an allowable range with respect to the faucet 200, generally the water discharge pipe 220. When a force in the rotational direction is applied beyond the above, each of the holders 214 is relatively rotated and displaced about the axis of one male screw member 216 corresponding to the adapter main body 212, and the faucet 200 is There has been a problem that the fixing strength in the rotation direction around the mounting hole 206 of the faucet 200 with respect to the counter 204 is weak, such as wobbling in the rotation direction.
In some cases, rotation of the holder 214 may cause the holder 214 to come off from the back surface of the counter 204 toward the mounting hole 206.

  The case where the faucet is attached to the mounting base such as a counter has been described above as an example, but the same problem is a problem that may occur in common when an article other than the faucet is attached to the predetermined mounting base.

Effects and effects of the invention

As described above, the mounting structure according to claim 1 is such that at least two male screw members are screwed to a single holder, and are screwed to the adapter main body. In the case of this mounting structure, The adapter body and the single holder are screw-fastened by a plurality of male screw members, so that the adapter body and the holder are relatively displaced in the rotational direction even when a rotational force is applied to the article in the article mounting state. Without increasing the fixing strength in the rotational direction.
Therefore, it is possible to solve the problem that the article is wobbling in the circumferential direction on the mounting surface of the mounting base such as a counter, or the problem that the holder is detached from the mounting base back surface to the mounting hole side.
According to the mounting structure of claim 1, the holder is inserted into the mounting hole from the free end side while maintaining the state in which the free end portion of the holder protrudes in the radial direction with respect to the adapter body. Thus, the insertion operation is facilitated, and the holder can be easily brought to an appropriate angular position on the back side of the mounting base by an operation from the front side of the mounting base.
Therefore, it is possible to easily attach the adapter device to the attachment base.
Thus, positioning means for positioning the other female screw hole of the holder at a position facing the other male screw member during the integral rotation can be provided.

  The present invention can be suitably applied particularly when the faucet is attached to a mounting base such as a counter (Claim 2).

  In the present invention, the holder and the adapter main body can be screw-fastened by the male screw member at at least two locations separated from each other along the periphery of the mounting hole.

The mounting structure of claim 4 is a curved shape corresponding to the mounting hole, which extends along the periphery of the mounting hole. According to this mounting structure, the holder is extended over a wide range, that is, around the periphery. It can be brought into contact with the back surface side of the mounting base over a long distance in the direction, so that the holding force of the mounting base by the holder and the adapter can be sufficiently increased.
Therefore, according to this mounting structure, only one holder can be provided for the adapter device, and the number of parts can be reduced.

  In addition, since the holder is long in the circumferential direction, the adapter body and the holder can be fastened to each other by a male screw member at a site that is greatly separated in the circumferential direction, and the deformation resistance force in the rotational direction between the adapter body and the holder Can be effectively strengthened, and the strength in the rotational direction can be increased.

In the mounting structure according to claim 4, since the holder has a curved shape corresponding to the mounting hole, even if the length of the holder is increased, for example, a faucet is provided to the mounting hole. When attaching a water supply pipe or the like for supplying water to the faucet, the holder does not get in the way, and an advantage that a wide space for piping etc. can be secured inside the attachment hole is obtained.
Here, the length of the holder in the circumferential direction can be set to a length equal to or longer than the half circumference of the mounting hole.

  Furthermore, in these cases, the holder can be screw-fastened to the adapter main body with the male screw member on one peripheral end side and the other peripheral end side.

  Furthermore, in this case, a projecting portion projecting toward the mounting hole is provided at one peripheral end portion and the other peripheral end portion, and these projecting portions are screwed to the adapter main body with a male screw member. (Claim 7).

Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows the water faucet attached to a counter (attachment base). In this figure, 10 is a faucet as an article, and 12 is a counter.
The faucet 10 is rotatably provided on the faucet body 14 standing upright from the counter 12, the water faucet 18 extending from the faucet body 14, and discharging water from the water outlet 16 at the tip, and the faucet body 14. And an operating lever 20.

The water discharge pipe 18 has a base end portion fixed to a cylindrical portion 22 rotatably provided on the faucet body 14, and the water discharge pipe 18 is rotatable in the left-right direction integrally with the cylindrical portion 22. .
The faucet body 14 is provided with a stopper portion (not shown) that defines the left and right pivot ends of the water discharge pipe 18, and the water discharge pipe 18 is only within an angle range defined by the stopper portions. It can be rotated in the left-right direction.

The faucet 10 is attached to the counter 12 at a faucet attachment hole (attachment hole) 24 provided in the counter 12.
26 is a supply pipe for supplying water and hot water to the faucet 10, and its upper end is connected to the faucet body 14 through the faucet mounting hole 24.

  As shown in FIG. 2, the faucet 10 is attached to the counter 12 by an adapter device 28.

4, 5, 6, 7, and 8 specifically show the configuration of the adapter device 28.
As shown in FIG. 4, the adapter device 28 includes an adapter main body 30, a holder 32, and a pair of male screw members 34 and 36.

The adapter main body 30 is a member that sits on the upper surface (mounting surface) of the counter 12 and sandwiches the counter 12 from the upper surface side, and has a cylindrical shape as a whole. An outward flange portion 38 is formed over the circumference. Then, on the lower surface of the flange portion 38, a liquid-tight seat is brought into contact with the upper surface of the counter 12 via the ring-shaped packing 40.
An annular protrusion 42 is formed downward on the lower surface of the adapter body 30. The ring-shaped packing 40 is attached to the lower surface of the adapter main body 30 in a fitted state with the annular protrusion 42.

  On the other hand, an annular seal groove 44 is formed on the outer peripheral surface of the adapter main body 30 in two upper and lower stages, and a ring-shaped packing 46 is attached thereto. The adapter main body 30 is in fluid-tight fitting contact with an inner peripheral surface of a cylindrical portion 48 (FIG. 2) described later at the lower end portion of the faucet main body 14 through the ring-shaped packing 46.

  On the inner peripheral surface of the adapter main body 30, semicircular bosses 50 (two in this example) projecting inward are provided (see FIG. 8). As shown in FIGS. 6 and 8, the boss portions 50 are formed with insertion holes 52 penetrating in the vertical direction, and the male screw members 34 and 36 are inserted downward from above. Yes.

On the inner peripheral surface of the adapter main body 30, semicircular protrusions 54 are formed at four locations that are spaced apart in the circumferential direction (see FIG. 8). A guide protrusion 56 is formed on the lower portion of the adapter main body 30.
These guide projections 56 are fitted to the faucet attachment hole 24 with a predetermined clearance when the adapter body 30 is attached to the counter 12 in the faucet attachment hole 24, and the adapter body 30 is positioned and guided.

  With these guide protrusions 56, the adapter main body 30 can be easily set at an appropriate position. That is, the lower surface of the adapter main body 30 can be correctly seated on the upper surface of the counter 12 around the faucet mounting hole 24, and the adapter main body 30 can be prevented from being set at a position biased with respect to the faucet mounting hole 24. . Thereby, a wide contact area, that is, a seal area can be secured between the adapter main body 30 and the upper surface of the counter 12.

2 and 4, the holder 32 is a member that sandwiches it from the back side of the counter 12, and a plurality of engaging teeth 58 are formed on the upper surface of the holder 32 over the entire length in the circumferential direction. The engaging teeth 58 are strongly pressed against the back surface of the counter 12.
The holder 32 as a whole has a curved shape, specifically a substantially arc shape, and its circumferential length is equal to or longer than the half circumference of the faucet mounting hole 24.

  The holder 32 is provided with projecting portions 60 and 62 projecting inward at positions in the vicinity of both ends in the circumferential direction. As shown in FIG. 6, the protruding portions 60 and 62 are formed with female screw holes 64 penetrating up and down, and the pair of male screw members 34 and 36 are respectively inserted into the female screw holes 64. It is designed to be screwed.

  One projecting portion 62 is formed at a lower position than the other projecting portion 60, and a substantially semicircular elastic clip (contact portion) 66 as a positioning means is provided on the upper surface thereof. Yes. The elastic clip 66 is formed in a direction and position whose center exactly coincides with the center of the female screw hole 64.

  One male screw member 34 of the pair of male screw members 34, 36 is longer than the other male screw member 36 by a certain length, and the male screw member 36 does not reach the female screw hole 64 in the holder 32. One male screw member 34 is screwed into the corresponding female screw hole 64, and its tip protrudes downward from the holder 32. Thus, a nut 68 (FIGS. 6 and 11) is screwed onto the tip of the male screw member 34 protruding downward from the holder 32.

  The nut 68 serves to prevent the holder 32 from falling off, and at the same time, functions as a lock nut (resistor) for rotating the holder 32 together with the male screw member 34 in a state before being mounted on the counter 12. Also serves as.

Next, a procedure for attaching the adapter device 28 of the present embodiment to the counter 12 will be described with reference to FIGS.
First, as shown in FIG. 9 (I), the longer male screw member 34 is inserted into the insertion hole 52 of the adapter body 30, and this is inserted into one female screw hole 64 of the holder 32, and its lower end is the holder 32. Screw in until it protrudes further downward. And the nut 68 is screwed with the lower end part protruded downward, and this is tightened to the full. At this time, the nut 68 functions as a lock nut, and the holder 32 rotates integrally with the male screw member 34, that is, rotates together.

Now, as shown in FIG. 9 (I), the holder 32 is left rotated about the male screw member 34, that is, the free end of the holder 32 protrudes in the radial direction with respect to the adapter body 30. In the state, as shown in FIG. 9 (II), the entire adapter device 28 is inclined, and in this state, the holder 32 is inserted into the faucet mounting hole 24 from the free end side.
By doing so, the holder 32 can be easily inserted into the faucet mounting hole 24 and positioned on the back side of the counter 12.

Subsequently, as shown in FIG. 10 (III), the male screw member 34 is rotated to rotate the holder 32 integrally on the back side of the counter 12. In other words, make them rotate together.
Thus, when the holder 32 rotates and moves to an appropriate position, the elastic clip 66 is elastically fitted to and abutted with the shorter male screw member 36 inserted in advance through the other insertion hole 52 of the adapter body 30. It becomes. Here, the female screw hole 64 formed in the projecting portion 62 is in a state of being just opposite to the shorter male screw member 36.

  Therefore, as shown in FIG. 11 (IV), the male screw member 36 is screwed into the opposed female screw hole 64 and the pair of male screw members 34 and 36 are further screwed in, so that the holder 32 of FIG. It is drawn upward from the position and brought into contact with the back surface of the counter 12, specifically, the back surface along the periphery of the faucet mounting hole 24 (FIG. 7).

  Further, by the subsequent screwing operation of the male screw members 34 and 36, the adapter main body 30 and the holder 32 are in a state of firmly sandwiching the counter 12 from both the front and back sides, and the adapter device 28 is attached to the counter 12 here.

At this time, the guide protrusion 56 of the adapter body 30 is fitted to the inner peripheral surface of the faucet mounting hole 24 with a predetermined clearance, and the lower surface of the flange portion 38 of the adapter body 30 is countered via the ring-shaped packing 40. 12 is seated in a watertight manner with a predetermined pressing force. FIG. 7 shows the state at this time.
As shown in FIG. 7, when the male screw member 34 is screwed in, the nut 68 functions as a lock nut, and thereafter acts only as a fall prevention member for the holder 32.

  When the adapter device 28 is mounted on the counter 12 in this way, the cylindrical portion 48 at the lower end portion of the faucet body 14 is then externally fitted to the adapter body 30 as shown in FIG. Is screwed into the female screw hole 78 of the adapter body 30 through the opening 74 of the cover ring 72 and the opening 76 of the cylindrical portion 48 that are rotatably attached to the faucet body 14. Here, the faucet body 14 and the adapter body 30 are connected and fixed to each other so as not to rotate.

  Then, the cover ring 72 is rotated to conceal the opening 76 and the retaining screw 70 of the cylindrical portion 48 in the faucet body 14 and the decorative cap 80 is fitted into the opening 74 of the cover ring 72 to open the opening. 74 is closed (see FIG. 2).

  In the case of the faucet mounting structure of the present embodiment, the two male screw members 34 and 36 are screwed to the single holder 32 and screwed to the adapter main body 30. Even when a rotational force is applied to the faucet 10 in the attached state, the holder 32 is not displaced relative to the adapter body 30 in the rotational direction, and a strong fixing strength is obtained in the rotational direction. Accordingly, it is possible to solve the problem that the faucet 10 swings in the same direction on the counter 12 or the holder 32 comes off to the faucet mounting hole 24 side.

Further, since the shape of the holder 32 is a substantially arc shape extending along the peripheral edge of the faucet mounting hole 24 and the circumferential length is increased, the holder 32 is extended over a wide range, that is, at a long distance in the circumferential direction. Thus, the counter 12 can be brought into contact with the back surface of the counter 12, so that the holding force of the counter 12 by the holder 32 and the adapter main body 30 can be sufficiently increased.
Therefore, according to this mounting structure, it is possible to provide only one holder 32 for the adapter device 28, and the number of parts can be reduced.

  Further, since the holder 32 is long in the circumferential direction, the adapter main body 30 and the holder 32 can be fastened to each other by male screw members 34 and 36 at a site far apart in the circumferential direction. It is possible to effectively increase the resistance to deformation in the rotational direction, and thus the strength in the rotational direction.

  Further, since the holder 32 has an arc shape corresponding to the faucet mounting hole 24, the holder 32 does not get in the way when the supply pipe 26 is passed through the faucet mounting hole 24, and the faucet mounting hole 24. A large space can be secured inside.

In this embodiment, since the elastic clip 66 is provided as positioning means for positioning the holder 32 in a state where the male screw member 36 and the female screw hole 64 are opposed to each other, the male screw member 36 is rotated by rotating the holder 32. This can be easily performed when screwing into the female screw hole 64.
In addition, in this case, the elastic clip 66 is elastically fitted to the male screw member 36 to prevent positional displacement, so that the holder 32 is rotated and positioned at a predetermined position, and in this state, the male screw member 36 is inserted into the female screw hole 64. When the screwing operation is performed, the holder 32 once positioned is not displaced, and the male screw member 36 can be screwed into the female screw hole 64 while the positioning state is reliably maintained.

In addition, in the case of the mounting structure of the present embodiment, when the holder 32 is inserted into the faucet mounting hole 24 in the state shown in FIG. The holder 32 can be integrally rotated only by rotating the 34, and the holder 32 can be easily brought to an appropriate angular position on the back side of the counter 12.
As a means for rotating the holder 32 together with the male screw member 34, a method of applying a coating material or grease to the male screw member 34 or the female screw hole 64 to increase the frictional force between them can be used.

  Further, in the present embodiment, the flange portion 38 is provided over the entire length in the circumferential direction on the seating surface side of the adapter body 30 on the counter 12, so that a wide contact area between the adapter body 30 and the upper surface of the counter 12, that is, a seal area. Can be secured.

Next, FIG. 12 shows another embodiment of the present invention. In this example, an arc-shaped stopper 90 is raised at the periphery of the female screw hole 64 on the holder 32 side, and this stopper 90 is connected to a male screw member. 36, the holder 32 is positioned in the rotational direction.
Even in this case, the male screw member 36 is made of a magnetic material as described above, and the stopper 90 is made of a magnet or attached with a magnet, so that the magnetic force between the male screw member 36 and the magnet Shaking between the male screw member 36 and the stopper portion 90 can be eliminated.

  FIG. 13 shows still another embodiment of the present invention. In this example, a long plate-like stopper portion 82 is suspended from the adapter main body 30, and this stopper portion 82 is brought into contact with the inner surface of the holder 32. Thus, the holder 32 is positioned so that the male screw member 36 and the female screw hole 64 of the holder 32 face each other correctly.

  FIG. 14 shows an example in which the holder is configured in another form. In this example, the holder has a rectangular plate shape, that is, a straight shape and a longitudinal shape, and the length in the longitudinal direction is larger than the diameter of the faucet mounting hole 24. A long holder 92 was used.

  In the case of this example, a pair of male screw members inserted in the insertion hole 52 of the adapter main body 30 on the upper surface side of the counter 12 while the holder 92 is disposed on the back surface side of the counter 12 so as to cross the faucet mounting hole 24 in the radial direction. 34 and 36 are screwed into a pair of female screw holes 64 formed in the holder 92, so that the counter 12 is sandwiched from both the front and back sides of the adapter body 30 and the holder 92, strictly, both longitudinal ends of the holder 92, The adapter device 28 is attached to the counter 12.

  Also in this example, since the adapter main body 30 and the holder 92 are screwed together by the pair of male screw members 34 and 36, a strong fixing strength can be obtained in the rotational direction.

FIG. 15 shows still another example.
In this example, the insertion hole 94 formed in the boss portion 50 of the adapter main body 30 has a long slot shape in the horizontal direction, and the pair of male screw members 34 and 36 inserted through the insertion hole 94 are in the insertion hole 94. It is possible to move in the horizontal direction.

  Moreover, the holder 96 in this example has a straight shape and a longitudinal shape as in FIG. However, the holder 96 includes an intermediate portion 98 and both end portions 100 and 100 in the longitudinal direction that are separate from the intermediate portion 98.

Both end portions 100, 100 are slidable in the longitudinal direction with respect to the intermediate portion 98. That is, in this example, the holder 96 can be expanded and contracted in the longitudinal direction.
Thus, in the case of the holder 96 of this example, the maximum dimension in the longitudinal direction, that is, the dimension in which the both end portions 100 and 100 are slid so as to be separated from each other is longer than the diameter of the faucet mounting hole 24. The extension amount is selected so as to be shorter than the diameter of the faucet mounting hole 24 in the minimum dimension of the above, that is, the dimension in which the both ends 100 and 100 are slid so as to approach each other.

  In addition, on the lower surfaces of both end portions 100, 100, inclined guide surfaces 102 that are inclined upward from the intermediate position in the longitudinal direction at each end portion 100, 100 toward the distal end side are formed.

Next, an example of a procedure for attaching the adapter device 28 in this example to the counter 12 will be described with reference to FIGS.
First, as shown in FIG. 16 (I), the holder 96 is extended to the maximum dimension, and this is inserted through the faucet mounting hole 24.

At this time, as shown in (II), the guide surface 102 comes into contact with the peripheral edge of the upper end of the faucet mounting hole 24. Therefore, when a downward pushing force is applied as it is, the holder 96 is automatically contracted and deformed to a state where the holder 96 can be inserted into the faucet mounting hole 24 by the guiding action of the inclined guide surface 102 as shown in (III). That is, both end portions 100, 100 slide and move in a direction approaching each other.
Further, as the two end portions 100 and 100 slide, the pair of male screw members 34 and 36 move in a direction approaching each other in the elongated hole-like insertion hole 94.

Then, the holder 96 is inserted into the faucet mounting hole 24 in a contracted state, and the holder 96 is extended after the insertion is completed as shown in FIG.
In this extension, a force may be applied to the male thread members 34 and 36 from the surface side of the counter 12 to spread the holder 96, or a return spring may be built in the holder 96 in advance. You may make it extend the both ends 100 and 100 by the elastic force of a return spring, ie, extend the holder 96. FIG.

  Thereafter, as shown in (V), the male screw members 34 and 36 are tightened, and the adapter device 28 is attached to the counter 12.

The adapter device 28 in this example can be attached to the counter 12 according to the procedure shown in FIG.
That is, the holder 96 is contracted in advance as shown in (I), and in this state, the holder 96 is inserted through the faucet mounting hole 24 as shown in (II), and the male screw members 34 and 36 are expanded after insertion. The adapter 96 can be mounted by extending the holder 96 and then tightening the male screw members 34 and 36.

FIG. 19 shows still another example.
In this example, the holder 104 is made of resin, and has a curved shape as a whole, specifically, a substantially arc shape.
In this example, the length of the holder 104 in the circumferential direction is equal to or longer than the half circumference of the faucet mounting hole 24.

The holder 104 has a notch 106 formed at an intermediate position in the circumferential direction, and a thin portion 108 is formed by the formation of the notch 106. The thin portion 108 can be elastically deformed in the closing direction in which both end portions in the circumferential direction approach each other, and can be restored to its original shape by its own restoring force when the elastic deformation force is removed.
In this example, the holder 104 is elastically deformed in the closing direction, so that it can be directly inserted into the faucet mounting hole 24 without being inclined as in the first embodiment.

  Thus, when the holder 104 is elastically deformed, it can be elastically deformed in a direction in which both ends are pinched by hand and the ends approach each other, that is, in a closing direction, or the shafts of the pair of male screw members 34 and 36 It can be elastically deformed in the closing direction by applying an inward force to the intermediate portion, or an inward force is applied to the pair of male screw members 34 and 36 in the portion exposed upward from the insertion hole 94. The holder 104 can be elastically deformed. Alternatively, the holder 104 can be elastically deformed based on a guiding action by the annular and inclined guide surface 102 on the lower surface of the holder 104.
