Description

  The present invention relates to a cover mounting structure, and specifically to a mounting structure of a “cover that covers a connector interposed between a faucet body and a terminal portion of a main pipe”.

  When installing a faucet in a predetermined installation part, the main part of the faucet (that is, the main part of the faucet with a built-in valve device for selecting stop water or a temperature control valve device) and the installation part And a terminal part of “original piping (for example, original piping for water supply or original piping for hot water supply)” that has reached the periphery of the pipe may be interposed. For example, when the faucet is installed on the wall, the terminal portion of the original pipe laid on the back side of the wall is taken out to the wall.

  Furthermore, while connecting one end part of a socket (one specific example of a connection tool) to the terminal part of original piping from the surface side (front side) of a wall part, the other end part of a socket is connected to a faucet body. Accordingly, the faucet body is supported on the wall portion using the connection tool, and water supply and hot water supply from the terminal portion of the original pipe to the faucet body can be performed. And in this kind of installation part, a connection tool is coat | covered with a predetermined | prescribed cover, and improvement of an aesthetics etc. may be aimed at.

  However, when this type of cover is attached, it may cause a construction error of the connector, create a useless gap between the attached cover and the wall, and reduce the aesthetics around the installation part. May cause problems. For this reason, in the “cover attachment structure” used when attaching this type of cover, an improvement intended to absorb this construction error has been made.

For example, a mounting structure has been proposed in which a groove is formed in the connector, a claw that engages and slides in the groove is formed in the cover, and the cover is slidable back and forth on the wall side and the faucet body side. (See Patent Document 1, hereinafter referred to as “Conventional Example 1”). Further, a flange is rotatably screwed to a screw portion exposed on the surface of the wall portion of the connection tool, and a cover is attached so as to cover the flange. Then, by rotating the cover, the flange is spirally rotated along the threaded portion of the connector and slid to the wall side, and the flange is pressed against the protrusion provided on the inner side of the cover in the direction of the wall, There has also been proposed an attachment structure in which a protrusion is sandwiched between a flange and a wall and a cover is fixed (see Patent Document 2, hereinafter referred to as “Conventional Example 2”).
JP 2003-64738 A JP 2003-56023 A

  However, in Conventional Example 1, when the cover is attached, it is necessary to push the cover toward the wall with reference to the connection tool, so the cover attachment work is complicated. In addition, the cover after attachment may inadvertently slide forward, creating a useless gap between the rear end portion of the cover and the wall portion. For this reason, the beauty of the surroundings of the wall (installation part) may be deteriorated, or “rattle” may occur in the cover.

  Further, in Conventional Example 2, not only the mounting structure is complicated, but also the cover mounting operation is complicated. That is, it is necessary for the operator to determine the amount of rotation of the cover (the amount of tightening of the flange) by hand during the cover mounting operation. In addition, when the cover is attached, the cover rotation amount (flange tightening amount) tends to be excessive or insufficient, which may cause the following problems. That is, the amount of rotation of the cover (the amount of tightening of the flange) becomes excessive, and the protrusion may be broken. Or the cover rotation amount (flange tightening amount) is insufficient, creating a useless gap between the rear end of the cover and the wall, reducing the aesthetics around the wall (installation), May cause "rattle".

  The present invention solves the above-mentioned problems, and can prevent the generation of a useless gap between the installation portion and the cover, has a simple structure, and is easy to construct, and has a cover mounting structure. The purpose is to provide.

  In the invention of claim 1, the cover (particularly the rear end portion) is attached to the connection tool while being pressed against the installation portion. For this reason, it can prevent that a clearance gap produces between the cover after attachment, and an installation part. Therefore, according to the first aspect of the present invention, it is possible to improve the aesthetic appearance around the installation portion (particularly, the cover mounting structure), and it is possible to prevent the cover after being mounted from becoming “rattle”. In addition, this attachment structure has a simple configuration of attaching to the connection tool while pressing the cover (particularly, the rear end portion) against the installation portion, and its construction is also easy.

The cover mounting structure of the invention of claim 2 is:
The terminal part of the original pipe and the water faucet are arranged on the surface side of the predetermined installation part and one end part is connected to the terminal part of the main pipe and the other end part is connected to the predetermined water faucet body. A cover mounting structure configured by mounting a predetermined cover on the surface side of the installation portion with respect to the connection tool interposed between the main body and
A predetermined biasing means is interposed between the connector and the cover, the cover is biased toward the installation portion by the biasing means, and the cover is pressed against the installation portion. It is characterized by.

  In the invention of claim 2, the cover (particularly, the rear end portion) is attached to the connector while being pressed against the installation portion by the urging force of the urging means. For this reason, also in invention of Claim 2, it can prevent producing a clearance gap between the cover after attachment, and an installation part. Therefore, according to the second aspect of the invention, it is possible to improve the appearance of the surroundings of the installation portion (particularly, the cover mounting structure) and to prevent the cover after mounting from being “rattle”. In addition, this attachment structure has a simple configuration in which the cover (particularly, the rear end portion) is attached to the connector while being pressed against the installation portion by the urging force of the urging means, and the construction thereof is also easy.

  Examples of the “installation part” of the invention of each claim include, in addition to the wall part, a deck part (also referred to as a base part), a counter part (for example, an upper surface part or a front surface part of the counter part), and the like. . In addition, as the “connector” of the invention of each claim, for example, a connector (so-called socket) configured in a substantially crank shape, a substantially L shape, a substantially square shape, a substantially straight tube shape, or the like. It can be illustrated. Furthermore, in each claim, the cover may be fixed to at least one of the connection tool and the installation part, or the cover may not be fixed to any of the connection tool and the installation part. Examples of the latter mode (non-fixed mode) include a state in which the cover is simply supported by the connector directly or via another member (for example, a spring member described later).

  When the faucet to which the invention of each claim is applied is a single faucet (when the faucet body is a faucet body for a single faucet), for example, one “end of the original pipe” One connection tool is interposed between the “portion” and the faucet body. In this case, when attaching a cover to this one connector, the invention of each claim can be applied. In this case, the single water faucet may discharge water, or may discharge hot water whose temperature is adjusted in advance on the primary side of the connector.

  When the faucet to which the invention of each claim is applied is a hot water / water mixing faucet (when the faucet body is a faucet body of hot water / water mixing), the “end part of the original piping” for hot water supply A hot water supply connection tool is interposed between the water faucet body and the water faucet body, and a water supply connection tool is interposed between the “water pipe terminal” and the water faucet body. In this case, each cover is attached to each cover to constitute each “cover attachment structure”, or the cover is attached to only one of the connectors (for example, a connector for hot water supply that tends to be hot). You may comprise the cover attachment structure. The invention of each claim may be applied to these “cover mounting structures”. In addition, while covering both the connecting tool for hot water supply and the connecting tool for water supply with a single cover, this cover and the connecting tool (one connecting tool or both connecting tools may be used). The application of the invention of each claim may be applied between

  Examples of the urging means of the invention of claim 2 include various elastic members such as rubber and resin foam in addition to “spring member (claim 3)” described later. The “biasing means” of the invention of claim 2 may be a separate body from the cover, or may constitute a part of the cover (biasing means protruding from the inner wall surface of the cover).

  In the invention of each claim, the positional relationship between the terminal portion of the original piping and the installation portion is not particularly limited. For example, (1) the end part of the original pipe is arranged on the back side of the installation part, and one end of the connection tool is inserted from the front side to the back side of the installation part through the mounting hole provided in the installation part. The aspect which connects the terminal part of a main piping, and the one end part of a connection tool, (2) While inserting the terminal part of a main piping into the attachment hole provided in the installation part from the back side of the installation part, A mode in which one end is inserted into the mounting hole from the surface side of the installation part, and the terminal part of the original pipe and one end part of the connector are connected in the mounting hole, (3) the terminal part of the main pipe is connected to the back surface of the installation part A mode of reaching the surface side of the installation part through the mounting hole provided in the installation part from the side, and connecting one end of the connector to the terminal part of the original pipe on the surface side of the installation part, (4) Arranging the terminal part on the surface side of the installation part (for example, a mode in which the terminal part of the original piping is raised from the floor surface in front of the wall part) , The manner of connecting the terminal portions of the original pipe one end portion of the connector on the surface side of the installation section, and the like can be exemplified.

The cover mounting structure of the invention of claim 3 is the cover mounting structure of claim 2,
The urging means is a spring member.

  In the invention of claim 3, the biasing means is constituted by a spring member having a simple structure. In addition, according to the invention of claim 3, since the urging means is constituted by a spring member separate from the cover, it is not necessary to provide the urging means on the cover itself. Therefore, according to the invention of claim 3, the structure of the “cover mounting structure” can be further simplified by simplifying the structure of the urging means and the cover.

  Examples of the “spring member” according to the third aspect of the invention include a leaf spring and a helical spring. Various methods for interposing the spring member between the connector and the cover can also be selected. For example, (1) a method of attaching and interposing a cover on a connection tool while a spring member is fixed or locked to the cover, and (2) a cover used as a connection tool with the spring member fixed or locked to the connection tool. Examples include a method of attaching and interposing, and (3) a method of fixing or locking the spring member to the connection tool and fixing or locking to the cover after the cover is attached to the connection tool.

  Here, as a method of “fixing”, it is preferable to use a restoring force accompanying elastic deformation of the spring member with respect to a predetermined part (especially, a concave portion, a groove portion, a convex portion, etc.) of the connection tool or the cover. Examples include a method of fixing using plastic deformation (caulking etc.) of a spring member, an aspect of fixing to a predetermined part of a connector or cover using an additional fixing means (adhesive, set screw, etc.), etc. it can. Moreover, as a method of "locking", the aspect which locks a spring member with respect to the predetermined part (especially it is desirable to comprise in a recessed part, a groove part, a convex part, etc.) of a connector and a cover can be illustrated. . However, the boundary between fixing and locking is not always clear, and when the spring member is locked to a predetermined part of the connector or cover, the spring member may be fixed to the predetermined part at the same time.

The cover mounting structure according to claim 4 is the cover mounting structure according to any one of claims 1 to 3,
The cover has a substantially cylindrical shape, a substantially conical shape, a substantially frustoconical shape, or a substantially box-shaped outer shape, and has openings on the front surface portion and the rear surface portion,
A plurality of divided bodies divided along the side edges are configured to be detachably combined.

  The invention of claim 4 has been made in view of the following points. That is, the cover according to claims 1 to 3 includes, for example, a cover that has an open portion on the bottom surface or the like and is attached to the connection tool while allowing the connection tool to pass through the open portion. However, like the cover of the invention of claim 4, when configured to surround the entire circumference of the connection tool (hereinafter referred to as "all-round type cover"), around the installation portion (in particular, the cover) The appearance of the mounting structure is further improved.

  By the way, in order to facilitate the attaching and detaching work of the all-round cover, it is effective to form the cover with two or more divided bodies (cover bodies). If the (position of the mating surface of the divided body) is present in a conspicuous location (upper part or the like), the aesthetics of the “cover mounting structure” are deteriorated. For this reason, in the invention of claim 4, the position of the dividing line (the position of the mating surface of the cover body) is arranged on the “side portion” that is not easily noticeable. And it is ensured by the invention of Claims 1-3 that the side part of a cover is faced in the right direction.

  That is, if the “cover mounting structure” of the above-described conventional example 2 is applied to an all-around cover configured by a divided body (cover body), the following problems occur. In Conventional Example 2, the amount of rotation applied to the cover when the cover is attached to the connector is determined according to the construction error of the connector. For this reason, the “posture around the center of rotation” of the cover does not always become a planned posture with the flange closed. That is, depending on the construction error of the connection tool, the dividing line may face an unplanned direction such as upward or obliquely upward, and the aesthetic appearance of the cover may not be ensured. In the conventional example 2, if the dividing line is forcibly directed in the planned direction, the amount of rotation (flange tightening amount) applied to the cover will be excessive or insufficient. If the amount of rotation applied to the cover becomes excessive (the amount of tightening of the flange is excessive), excessive stress is applied to the protrusions of the cover, and the protrusions may be damaged and uselessly deformed. On the other hand, if the amount of rotation applied to the cover is insufficient (the amount of tightening of the flange is insufficient), there may be problems such as creating a useless gap with the wall or causing "rattle" on the cover. There is.

  On the other hand, according to the fourth aspect of the present invention, when the cover is attached, it is not necessary to add rotation to the cover. In other words, while the cover is properly pressed against the installation part, the position of the dividing line (the position of the mating surface of the cover body) is surely placed on the inconspicuous “side part” and around the installation part (especially The aesthetics of the cover mounting structure) can be improved.

  In the invention of claim 4, for example, (a) a connection portion (hereinafter referred to as “primary connection portion”) between the one end portion of the connection tool and the terminal portion of the original pipe, and the other end portion of the connection tool and water. The connection part with the plug body (hereinafter referred to as “secondary side connection part”) may be arranged outside the cover, or (b) both “primary connection part” and “secondary side connection part”. You may arrange | position in a cover, (c) One of a "primary connection part" and a "secondary side connection part" may be arrange | positioned outside a cover, and the other may be arrange | positioned in a cover. More specifically, the aspect of (a) will be described. One end of the connector is exposed from the “opening portion of the rear surface (rear end) of the cover”, and the other end of the connector is connected to the cover. Cover the other part of the connector (excluding the one end and the other end) with the cover, and expose the rear part of the cover (rear end) The aspect which press-contacts the opening part of a part) to an installation part can be illustrated.

The cover mounting structure according to claim 5 is the cover mounting structure according to any one of claims 1 to 4,
An opening for performing at least one of operation and attachment / detachment of the faucet-related parts arranged in the connector is formed in the lower part of the cover.

  According to the invention of claim 5, the operability of the faucet-related parts is improved (that is, it can be operated with the cover attached), and the faucet-related parts are maintained (replaced, maintained, etc.). Workability) can be improved. In addition, since the opening is formed in the “lower part of the cover” that is not conspicuous, this opening does not deteriorate the aesthetics of the “cover mounting structure”.

  Here, as the “water faucet related part” of the invention of claim 5, for example, (a) it is disposed in an internal flow path (for example, a flow path from one end side to the other end side) in the connector. “Stop valve”, (b) “strainer (filter)” disposed in this internal flow path, (c) “check valve” disposed in this internal flow path, (d) disposed in this internal flow path In addition, a “unit” or the like that integrally includes two or more of “a stop cock”, “strainer (filter)”, and “a check valve” can be exemplified.

  As described above, according to the cover mounting structure of each invention, it is possible to prevent the useless gap from being generated between the installation portion and the cover. In addition, the cover mounting structure of each of the present inventions has a simple configuration and is easy to construct.

The flow path 13 includes three bent portions 13a, 13b, and 13c, and a configuration in which four linear flow path portions are connected. That is, (a) a substantially horizontal flow path portion (hereinafter referred to as “first flow path portion”) extending from the primary side connecting portion 11 to the bent portion 13a (most primary side bent portion); ) A substantially downward inclined channel portion (hereinafter referred to as a “second channel portion”) 14a from the bent portion 13a to the bent portion 13b adjacent to the secondary side thereof, and (c) the bent portion 13b to the second portion. A flow path portion (hereinafter referred to as “third flow path portion”) 14b that rises in the direction of the bent portion 13c adjacent to the secondary side, and (d) a substantially horizontal line extending from the bent portion 13c to the connection portion 12 on the secondary side. A flow channel portion (hereinafter referred to as “fourth flow channel portion”).

  As shown in FIG. 3, a female screw portion 15a is provided on the inner wall of the wall body portion 15 that forms the substantially upper half of the second flow path portion 14a of the connector 10A (10B). The female screw portion 15a is a portion for screwing a “water stopcock 18” described later. Further, in the connector 10A (10B), the peripheral portion on the secondary outlet side of the wall portion 15 is a valve seat portion 15b on which the stop cock 18 is seated.

  As shown in FIG. 3, on the outer wall portion of the connector 10 </ b> A (10 </ b> B), the faucet-related component attaching / detaching portion (hereinafter, (Referred to as "detachable part") 16 is formed in a protruding shape. The detachable portion 16 has a substantially cylindrical shape, and has a lower end portion as an opening portion and an internal space communicating with the bent portion 13b. Further, the axial center of the detachable portion 16 and the axial center of the wall portion 15 are aligned coaxially. The attaching / detaching portion 16 is integrated with the bent portion 13b and the wall portion 15 and constitutes a mounting portion of a stop cock with a strainer (hereinafter referred to as a “stop cock unit”) U. Furthermore, a female screw portion 16 b is provided on the inner wall surface of the detachable portion 16.

  As shown in FIG. 3, the stop cock unit U includes a stop cock 18, a strainer S, and a lid 19. Among these, the lid body 19 is formed in a “substantially cylindrical shape” having a flange portion at an end portion on the exposure side (an end portion exposed when attached to the detachable portion 16), and the operation hole 19 c at the axial center position. Is penetrated. Further, a male screw portion 19d is formed on the peripheral surface portion of the portion on the mounting side (the portion that is not exposed when mounted on the detachable portion 16). The lid 19 is detachably mounted on the detachable portion 16 by screwing the male threaded portion 19d with the female threaded portion 16b. Further, at the time of mounting, the operation hole 19c and the axis of the wall portion 15 are aligned coaxially.

  The water stop cock 18 is configured in an axial shape, and forms a valve body (configured using packing or the like) 18a in an intermediate portion along the axial direction. Moreover, while providing the external thread part 18b in the outer peripheral surface of the one end part side along an axial direction, let the other end part side along the axial direction be the operation part 18c. A tool hook 18d is provided on the end surface of the operation portion 18c. The water stop cock 18 is incorporated in the connector 10A (10B) in a state where the male screw portion 18b is screwed into the female screw portion 15a and the operation portion 18c is inserted into the operation hole 19c.

  The strainer S is formed in a substantially cylindrical shape, and the opening on one end side is fixed to the back side of the lid body 19 (the side disposed inside the connection tool 10A, 10B), and at the outside of the stop cock 18. Are arranged at intervals. That is, the axial center of the strainer S is coaxial with the axial center of the lid 19 and the water stop cock 18.

As a result, the water supply connector 10 </ b> B is supported by the wall portion 1 on the surface 1 a side of the wall portion 1.

  In any case, a “seal tape” is wound around the outer peripheral surface of the primary-side connecting portion 11, and the screwing amount of the male screw portion 11 a to the terminal portions 3 A and 3 B (adapter 32) is adjusted to an appropriate amount. The For this reason, the connecting tool 10A for hot water supply and the connecting tool 10B for water supply can be fixed in a correct posture (for example, the state where the opening of the attaching / detaching portion 16 faces obliquely downward).

  A connecting portion 7A for hot water supply of the faucet body 7 is connected to the secondary side connecting portion 12 (that is, the other end portion) of the connecting tool 10A for hot water supply using a cap nut 12a or the like. In addition, a connection portion 7B for water supply of the faucet body 7 is connected to the connection portion 12 (that is, the other end portion) on the secondary side of the connection tool 10B for water supply using a cap nut 12a or the like. . As described above, the cover 20A (20B) is attached via the spring members 50A and 50B to the connector 10A (10B) that is configured and installed. Next, the cover 20A (20B) and the spring members 50A and 50B will be described in detail.

  As shown in FIG. 1, the cover 20 </ b> A (20 </ b> B) has a substantially frustoconical outer shape, includes a front opening 21 a on the front surface 21 and a rear opening 22 a on the rear surface 22. Further, an opening 23 for maintenance is opened at the bottom (lower part). In the cover 20A (20B), the primary side connecting portion 11 is exposed rearward through the rear opening 22a, and the secondary side connecting portion 12 (and the cap nut 12a) is exposed forward through the front opening 21a. ing. Furthermore, the detachable portion 16 and the lower end portion of the unit U are exposed obliquely downward through the “maintenance opening 23”. The cover 20A (20B) covers substantially the entire area of the connector 10A (10B).

  The cover 20A (20B) is divided into two cover bodies 31 and 41 along the dividing line L on the side (see FIG. 8A). That is, as shown in FIG. 2, the cover 20 </ b> A (20 </ b> B) includes an upper cover body 31 that constitutes an upper half portion thereof and a lower cover body 41 that constitutes a lower half portion thereof. The upper cover body 31 and the lower cover body 41 constitute a specific example of a divided body.

  As shown in FIGS. 2 and 4, the upper cover body 31 has an inner wall surface 31 a as a concave portion and front and rear ends and a bottom surface as open portions. In the inner wall surface 31a, a fixing portion 33 to which a “spring member 50A (50B)” to be described later is fixed is provided at the center along the circumferential direction of the cover 20A (20B). The fixing portion 33 is configured in a substantially container shape protruding from the inner wall surface 31 a of the upper cover body 31. A rib 33a protrudes from one of a pair of opposing wall surfaces of the fixed portion 33. The ribs 33a are provided at predetermined intervals along the circumferential direction of the cover 20A (20B).

  The upper cover body 31 is provided with contact portions 34a and 34b at positions on both end sides along the circumferential direction of the cover 20A (20B) on the inner wall surface 31a. These abutting portions 34a and 34b have projecting end surfaces that are substantially horizontal, and project substantially cylindrical slide projections 35a and 35b from the projecting end surfaces. Further, the upper cover body 31 has engaging projections 36a to 36d protruding from the four corners of the inner wall surface 31a.

  As shown in FIGS. 2 and 5, the lower cover body 41 has an inner wall surface 41 a as a concave portion, and both front and rear ends and an upper surface as open portions. In the inner wall surface 41a, the above-described “maintenance opening 23” is provided at the center along the circumferential direction {a portion corresponding to the bottom of the cover 20A (20B)}. Further, the lower cover body 41 has a pair of slide storage portions 45a and 45b projecting in a substantially cylindrical shape from the positions on both end sides along the circumferential direction of the cover 20A (20B) on the inner wall surface 41a. The slide storage portions 45a and 45b can be aligned with the slide protrusions 35a and 35b when the upper cover body 31 and the lower cover body 41 are combined. Further, these slide storage portions 45a and 45b open a storage space into which the slide protrusions 35a and 35b can be fitted upward.

  That is, when the upper cover body 31 and the lower cover body 41 are combined, each slide protrusion is housed in the corresponding slide housing portion in a fitting manner (35a is housed in 45a and 35b is housed in 45b). The upper cover body 31 and the lower cover body 41 can be accurately aligned (see FIG. 6).

  Further, the engagement protrusions 46 a to 46 d protrude from the four corners of the inner wall surface 41 a of the lower cover body 41. These engagement protrusions 46a to 46d are provided at positions where they can be aligned with the engagement protrusions 36a to 36d that correspond to the upper cover body 31 when the upper cover body 31 and the lower cover body 41 are combined. Yes. That is, as shown in FIGS. 7A and 7B, when the upper cover body 31 and the lower cover body 41 are combined, the engaging protrusions (36 a) that are in a corresponding relationship between the upper cover body 31 and the lower cover body 41. 46a, 36b and 46b, 36c and 46c, and 36d and 46d) are engaged with the male engaging portion 36A and the female engaging portion 46A. Thereby, careless detachment of the upper cover body 31 and the lower cover body 41 is prevented.

  The spring members 50A and 50B are configured by using leaf springs, and as shown in FIGS. 8B and 8C, the spring main body 51, the first hook-like portion 52, and the second hook-like portions 53 and 53 are formed. And.

  Among these, the spring main body 51 is configured in a horizontally long rectangular shape. Further, the first hook-like portion 52 protrudes in a bent shape from one side edge along the longitudinal direction of the spring main body portion 51. And it has the substantially hook shape which turned up the protrusion part in the substantially semicircle shape. Further, the second hook-shaped portions 53 and 53 protrude in a bent shape from both ends at the other side edge along the longitudinal direction of the spring main body portion 51. And these 2nd hook-shaped parts 53 and 53 are also provided with the substantially hook shape which turned up the protrusion part in the substantially semicircle shape.

  The mounting structure T configured as described above is constructed as shown in FIGS. 9 and 10, for example. That is, as shown in FIG. 9, in front of the wall portion 1 (on the surface 1a side), the primary side connection portions 11 of both the connectors 10A and 10B are connected to the corresponding end portions 3A and 3B of the original piping. While connecting, the connection part 12 of the secondary side of both connection tools 10A and 10B is connected to the corresponding connection parts 7A and 7B of the faucet body 7. That is, the faucet body 7 is fixed to the wall portion 1 via both the connecting tools 10A and 10B in front of the wall portion 1 (on the surface 1a side).

  In this state, as shown in FIGS. 4B and 9, the covers 20A and 20B are attached to the respective connecting devices 10A and 10B. That is, in both the hot water supply side cover 20 </ b> A and the water supply side cover 20 </ b> B, first, the spring members 50 </ b> A and 50 </ b> B are fixed to the inner wall surface 31 a of the upper cover body 31. Specifically, the operator grasps the first hook-shaped portion 52 by hand and elastically deforms the shape so that the shape is crushed (elastically deforms so as to increase its curvature). The convex part is inserted into the fixing part 33 with the upward direction.

  Then, when the hand is released from the first hook-shaped portion 52, the restoring force (elastic force for restoring the state before elastic deformation) generated in the first hook-shaped portion 52 is released from the first hook-shaped portion 52 to the fixing portion 33. In addition, the first hook-shaped portion 52, and thus the spring members 50 </ b> A and 50 </ b> B, are fixed to the upper cover body 31. At this time, in the first hook-like portion 52, the one surface portion is uniformly in contact with the smooth surface of the fixing portion 33, and the other surface portion in a relationship between the one surface portion and the front and back is continuously arranged at a predetermined interval. The end surface of the rib 33a contacts intermittently. That is, the contact area between the other surface portion and the fixing portion 33 is reduced, and the contact portions are dispersed along the width direction of the other surface portion. That is, since a sufficiently large pressure is applied to the spring members 50A and 50B from the end positions of the ribs 33a that are continuously arranged, the first hook-like portion 52 is firmly attached to the fixing portion 33. Fixed to.

  In this state, as shown in FIG. 9, the upper cover body 31 is attached to the connecting tools 10A and 10B from above, and the lower cover body 41 is attached to the connecting tools 10A and 10B from below. Then, the upper cover body 31 and the lower cover body 41 are combined with the upper cover body 31 and the lower cover body 41 in a state in which the connectors 10A and 10B are substantially surrounded. Thereby, the attachment to cover 10A, 10B of cover 20A, 20B is completed.

  When combining the upper cover body 31 and the lower cover body 41, as shown in FIGS. 6A and 6B, the slide protrusions 35a and 35b are slid and stored in the corresponding slide storage portions 45a and 45b. The upper cover body 31 and the lower cover body 41 are aligned. When the slide storage of the slide protrusions 35a and 35b into the slide storage portions 45a and 45b is completed, the projecting end surfaces (lower surfaces) of the contact portions 35a and 35b and the corresponding slide storage portions 45a and 45b. The upper end surface of the abutment comes into contact, and further slide storage is prohibited. At this time, the peripheral edge portion 31A of the upper cover body 31 and the peripheral edge portion 41A of the lower cover body 41 abut {see FIG. 8A}, and the combination of the upper cover body 31 and the lower cover body 41 is completed.

  Further, when the combination of the upper cover body 31 and the lower cover body 41 is completed, the engagement protrusions 36a to 36d and the corresponding engagement protrusions 46a to 46d are engaged (see FIG. 7), and the upper cover body. 31 and the lower cover body 41 are fixed.

  In the present embodiment, when the cover 20A, 20B is attached, the second hook-like portions 53, 53 hanging from the both ends of the spring main body 51 are connected to both the connecting devices 10A, 10B. Are recessed in a resilient manner. That is, when the upper cover body 31 is moved from the upper side to the lower side and attached to the connecting devices 10A and 10B, both the second hook-shaped portions 53 and 53 are placed in the concave portions 17 and 17 with their convex portions directed downward. Insert into. At this time, both the second hook-shaped portions 53 and 53 are inserted into the corresponding locking recesses 17 and 17 while being elastically deformed so as to be crushed (elastically deformed so as to increase their curvature). The That is, on the basis of the operator, the second hook-shaped portion 53 hanging from the left end side of the spring main body 51 is inserted into the left concave portion 17, and the second hook-shaped portion 53 hanging from the right end side of the spring main body 51 is It is inserted into the recess 17 on the right side. That is, the spring members 50A and 50B are mounted in such a state that the two hook-shaped portions 53 and 53 straddle the connection tools 10A and 10B from above.

  When the insertion of the second hook-shaped portions 53, 53 into the concave portions 17, 17 is completed, the restoring force generated in the second hook-shaped portions 53, 53 (elastic force that tries to restore the state before elastic deformation). Is added to the inner walls of the recesses 17, 17. As a result, the second hook-like portions 53 and 53, and consequently the spring members 50A and 50B, are locked to the connection tools 10A and 10B. At this time, the upper cover body 31 is supported by the connectors 10A and 10B via the spring members 50A and 50B. For this reason, the lower cover body 41 integrated with the upper cover body 31 is also supported by the connectors 10A and 10B via the spring members 50A and 50B.

  In the present embodiment, when the covers 20A and 20B are attached, the spring members 50A and 50B (particularly, the portion 53a adjacent to the spring main body 51 in the second hook-shaped portion 53) are elastically deformed as shown in FIG. Arise. That is, the size of the spring members 50A and 50B, the relative positional relationship between the mounting positions of the spring members 50A and 50B and the wall portion 1 are appropriately selected. Accordingly, when the attachment of the covers 20A and 20B is completed, the covers 20A and 20B are attached to the spring members 50A and 50B (particularly, the portion 53a close to the spring main body 51 in the second hook-shaped portion 53) in the direction of the wall 1. An “elastic force (biasing force) P” is generated so as to be biased (moved). For this reason, the cover 20A, 20B after completion of the attachment is pushed into the surface 1a side of the wall portion 1 by the urging force of the spring members 50A, 50B. At this time, the entire region of the rear opening 22a constituting the rear surface portion 22 (rear end portion) of the covers 20A and 20B is in close contact with the surface 1a of the wall portion 1 in a press-contact manner. And after construction of the mounting structure T (during use of the mounting structure T), an unnecessary gap is generated between the rear surface portion 22 (rear end portion) of the covers 20A and 20B and the surface 1a of the wall portion 1. Absent.

  According to this mounting structure T, no gap is generated between the cover 20A, 20B and the wall portion 1 after mounting. Therefore, it is possible to improve the beauty of the periphery of the wall portion 1 (particularly, the present mounting structure T), and to prevent “rattle” from occurring in the covers 20A and 20B. In addition, the mounting structure T uses a simple configuration in which the cover (particularly, the rear surface portion 21) is simply pressed against the wall portion 1 by the spring members 50A and 50B and is easy to construct.

  Further, the urging means is constituted by the spring members 50A and 50B having a simple structure, and it is not necessary to provide the urging means on the covers 20A and 20B themselves. Therefore, the structure of the mounting structure T is further simplified. Furthermore, the outer shapes of the covers 20A and 20B are substantially frustoconical, and the cover 20A and 20B are divided along the sides while improving the aesthetic appearance of the mounting structure T. In other words, the covers 20A and 20B are divided, and the position of the dividing line L is arranged on the “side portion” that is not easily noticeable while facilitating the attaching / detaching operation. Moreover, since it is not necessary to rotate the covers 20A and 20B, the position of the dividing line L is surely arranged on the “side portion” that is not easily noticeable, and is mounted around the wall portion 1 (particularly, this mounting structure T). T's aesthetics can be surely secured.

  Furthermore, in this embodiment, since the cover 20A, 20B is provided with the “opening 23 for maintenance”, the operability of the stop cock 18 is improved, and the maintenance (replacement, care, etc.) of the strainer S is performed. Workability is improved. Moreover, since the “maintenance opening 23” is formed in the “under the covers 20A and 20B” which is not conspicuous, the appearance of the mounting structure T is not deteriorated by the opening 23.

  The scope of each invention is not limited to the specific modes shown in the above embodiments, and various modifications can be exemplified within the scope of each invention.

  That is, unlike the present embodiment, the urging means (spring members 50A, 50B) are fixed or locked to the connectors 10A, 10B in advance. Thereafter, when attaching the covers 20A and 20B to the connectors 10A and 10B, the urging means (spring members 50A and 50B) may be fixed or locked to the covers 20A and 20B.

  Further, unlike the present embodiment, the invention of each claim may be applied to installation parts other than the wall part 1. For example, in the case where the faucet body is supported by the connection tool raised from the deck part (base part), the attachment structure of the invention of each claim may be applied to the cover that covers the connection tool. . Further, the terminal portions 3A and 3B of the original pipe are raised on the surface 1a side of the wall portion 1 (in front of the wall portion 1), and the connectors 10A and 10B connected to the terminal portions 3A and 3B of the original pipe and Further, the mounting structure of the invention of each claim may be applied to the covers 20A and 20B covering these. In this case, for example, if the lower surface portion on the rear end side of the cover 20A, 20B is provided with a passage hole or a notch for passage through which the terminal portions 3A, 3B of the original pipe are passed, the rear end of the cover 20A, 20B The portion can be reliably pressed against the surface 1 a of the wall portion 1.

  In addition, the present embodiment is an example in which one fixing portion 33 is provided on the covers 20A and 20B, but a plurality of fixing portions 33 may be provided along the mounting surface direction. For example, as shown in the modification of FIG. 11, a plurality of fixing portions 33 that are different in distance from the installation portion 1 a may be provided to the covers 20 </ b> A and 20 </ b> B (in FIG. 11, Although an example in which two fixing portions 33 are provided is illustrated, three or more fixing portions 33 may be provided. By doing so, the spring members 50A and 50B can be attached to the more stable fixing portion 33, and the covers 20A and 20B can be attached in a balanced state.

  For example, if the connectors 10A and 10B protrude more than expected on the surface 1a of the installation part 1 or are retracted and attached, the distance between the locking recess 17 and the surface 1a of the installation part 1 is long. Become shorter or shorter. Therefore, when the number of the fixing portions 33 is one, the spring members 50A and 50B are not fitted when the distance is short, and when the distance is long, a gap is generated between the covers 20A and 20B and the surface 1a of the installation portion 1. Moreover, since the spring members 50A and 50B push the upper ends of the covers 20A and 20B, the entire covers 20A and 20B may be inclined.

  The present invention can be used, for example, in the field of manufacturing, selling, installing, processing and the like of faucets.
