In the connecting device 100, the tubular member 140 may be omitted. Alternatively, in the present invention, the tubular member 140 may be interpreted as the "first connection target member" to which the connecting device 100 is connected without including the tubular member 140 in the configuration of the connecting device 100.

First, the configuration of the joint body 110 of the present embodiment will be described with reference to FIGS. 2 to 5. 2 (a) and 2 (b) are schematic perspective views of the joint body 110. 3A to 3D are a front view, a side view, a plan view, and a bottom view of the joint main body 110. 4 (a) and 4 (b) are a cross-sectional view taken along the line AA and a cross-sectional view taken along the line BB of the joint body 110. FIG. 5 is an exploded perspective view of the joint body 110.

The joint body 110 of the present embodiment is a hollow cylindrical body extending in the axial direction. The joint body 110 is made of a synthetic resin that can be flexed and deformed. As shown in FIG. 2, the joint body 110 is directly or indirectly connected to the device 11 to flow in drainage, a connecting cylinder portion 111, a flowing water cylinder portion 112 communicating with the connecting cylinder portion 111, and the flowing water cylinder. A peripheral wall portion 113 that surrounds the portion 112 and is connected to the lower end of the connecting cylinder portion 111, a receiving portion 116 that is connected to the lower end of the peripheral wall portion 113 and receives the drainage flowing out from the flowing water cylinder portion 112, and the receiving portion 116. It is provided with a drainage section 117 for discharging the drainage to the drainage pipe 15. The connecting cylinder portion 111, the flowing water cylinder portion 112, the receiving portion 116, and the drainage portion 117 are arranged concentrically with each other.

As shown in FIG. 4, the connecting cylinder portion 111 has a hollow cylindrical shape extending in the axial direction. At the tip (upper end) of the connection cylinder 111, an upstream connection port 111a is formed as an inflow port for drainage from the device 11, and the male screw portion 12 of the device 11 is directly connected to the upstream connection port 111a. Connected objectively or indirectly. In the present embodiment, the upstream side connection port 111a communicates with the discharge port at the lower end of the male screw portion 12. The size of the upstream connection port 111a is arbitrarily determined according to the target of the connection destination. Further, at the tip of the connection cylinder portion 111, an annular groove 111b extending in the entire circumferential direction is recessed at a position recessed in the axial direction from the upstream side connection port 111a. In other words, the outer diameter of the annular groove 111b is smaller than the portion located on the tip side of the annular groove 111b (the tip end portion of the connecting cylinder portion 111). The annular groove 111b functions as an engaged portion in which the locking claw 135 as an engaging portion of the connector member 130 described later is engaged in the axial direction. That is, the axial width of the annular groove 111b is configured so that the locking claw 135 can be arranged. Further, in the connection cylinder portion 111, the outer peripheral surface of the portion on the tip end side of the annular groove 111b is defined as the adhesive surface 111c to be adhered to the adhered surface 141 of the tubular member 140 (or the first connection target member) described later. Has been done. Further, an annular flange 111d is formed overhanging on the lower end side of the connecting cylinder portion 111. The peripheral wall portion 113 extends downward from the lower surface of the flange 111d. In the present embodiment, the inner side of the connecting cylinder portion 111 behind the annular groove 111b has substantially the same diameter as the adhesive surface 111c, but may have a different diameter from the adhesive surface 111c.

The flowing water cylinder portion 112 is a straight cylindrical body integrally connected to the lower end side of the connecting cylinder portion 111. The flowing water cylinder portion 112 has a reduced diameter from the lower end of the cylindrical connecting cylinder portion 111 and extends downward. A circular water passage port 112a is opened at the upper end of the water flow cylinder portion 112, and communicates with the upstream connection port 111a of the connection cylinder portion 111. At the lower end of the water flow cylinder portion 112, an outflow outlet 112b that allows drainage from the upstream side connection port 111a to flow downward through the water passage port 112a is opened. The outlet 112b has a circular shape with a radius r1. Further, the flowing water cylinder portion 112 is extended to a predetermined length inside the peripheral wall portion 113 so as to be close to the receiving portion 116. In other words, the outflow port 112b at the lower end of the water flow tube portion 112 is separated from the receiving portion 116 by a predetermined distance. Further, a plurality of recesses 112c extending in the axial direction are recessed on the inner peripheral surface of the flowing water cylinder portion 112. The plurality of recesses 112c are open at the lower end side, and function to guide the drainage to flow down from the outlet 112b so as not to scatter outward in the radial direction.

The peripheral wall portion 113 is formed in a cylindrical shape extending in the axial direction, and connects the lower portion of the connecting cylinder portion 111 and the upper portion of the receiving portion 116. More specifically, it extends downward from the lower surface of the flange 111d of the connecting cylinder portion 111 and is integrally connected to the end face of the receiving port 116a of the receiving portion 116. A plurality of (two in this embodiment) openings 114 are bored on the side of the peripheral wall portion 113 in order to open the drainage path to the atmosphere. As a result, the drainage port space 115 is defined inside the peripheral wall portion 113. Then, the flowing water cylinder portion 112 extends in the axial direction inside the drainage port space 115 so as to be inserted into the peripheral wall portion 113. The opening 114 is formed in a rectangular shape on both the front surface and the back surface, and the peripheral wall portion 113 is cut out from the upper end to the lower end thereof. That is, the opening 114 opens from the base end of the flowing water cylinder portion 112 (or the lower end of the connecting cylinder portion 111) to the upper end of the receiving portion 116. As a result, the opening 114 opens from the receiving port 116a to the upper side of the outlet 112b, and at least a part of the outer surface of the water flow cylinder portion 112 is exposed sideways together with the outlet 112b from the opening 114.

The receiving portion 116 is arranged below the peripheral wall portion 113, and is configured in a cup shape so as to receive the drainage from the outlet 112b. More specifically, the receiving portion 116 has a short cylindrical shape on the upper side and a tapered diameter on the lower side. A receiving port 116a having a circular opening is provided at the upper end of the receiving portion 116. The inner diameter of the socket 116a is larger than the inner diameter of the outlet 112b. Further, the receiving port 116a and the outlet 112b are separated from each other by a predetermined distance. Since the peripheral wall portion 113 and the receiving portion 116 are integrally connected to each other, the boundary between the two can be appropriately interpreted. However, in the present embodiment, the lower edge of the opening 114 is the receiving portion 116. It was defined as the peripheral edge of the receiving port 116a.

The drainage portion 117 is integrally connected to the lower end of the tapered portion of the receiving portion 116. The drainage portion 117 communicates with the receiving portion 116, and functions to discharge the drainage flowing from the receiving portion 116 from the joint main body 110 to the drainage facility. The drainage portion 117 is a cylindrical body having a diameter smaller than that of the receiving portion 116, and has a downstream connection port 117a at the lower end thereof. The joint body 110 is connected to the connection port of the drain pipe 15 via the downstream connection port 117a.

As shown in FIG. 5, the joint body 110 is formed by joining the upper member 110a and the lower member 110b. The connecting cylinder portion 111 and the flange 111d are integrally formed on the upper member 110a. The peripheral wall portion 113, the receiving portion 116, and the drainage portion 117 are integrally formed on the lower member 110b. The claw 111e near the lower end of the connecting cylinder portion 111 of the upper member 110a engages with the engagement hole 113a formed near the upper end of the peripheral wall portion 113, and the upper end edge of the peripheral wall portion 113 abuts on the lower surface of the flange 111d. The upper member 110a and the lower member 110b are joined. These members may be joined by fitting, or may be integrally bonded with an adhesive or the like. That is, since the joint body 110 can be integrally configured, it has a simple configuration.

In the present embodiment, the joint body 110 is manufactured by molding from a synthetic resin. However, the present invention is not limited to this, and the joint body may be formed of another material such as metal or glass. Further, in the present embodiment, the upper member 110a and the lower member 110b as separate bodies are combined, but the entire joint body may be integrally molded.

It is provided with an upper wall portion 133 that connects the cylinder portion 131 and the outer cylinder portion 132. The connector member 130 is made of synthetic resin and can be elastically deformed so as to bend in the radial direction. The inner cylinder portion 131 has a cylindrical shape and is open on both sides in the axial direction. The outer cylinder portion 132 has a polygonal surface on the outer surface and a circumferential surface on the inner surface, and is open only on the lower side in the axial direction. That is, the side facing the upper wall portion 133 is open between the inner cylinder portion 131 and the outer cylinder portion 132. The inner cylinder portion 131 is longer in the axial direction than the outer cylinder portion 132. Further, the inner cylinder portion 131 is inserted into the connecting cylinder portion 111, and the outer cylinder portion 132 is configured to be fitted into the connecting cylinder portion 111. That is, the outer diameter of the inner cylinder portion 131 is smaller than the inner diameter of the tip portion of the connecting cylinder portion 111, and the inner diameter of the outer cylinder portion 132 is larger than the outer diameter of the tip portion of the connecting cylinder portion 111. It is preferable that these diameter differences are small so as to suppress rattling between the connector member 130 and the connecting cylinder portion 111. Further, a female screw portion 134 is formed on the inner peripheral surface of the inner cylinder portion 131. The female threaded portion 134 as the threaded portion is screwed into the male threaded portion 12 (second connection target member) of the device 11 as the threaded portion. In the present embodiment, the female screw portion 134 as the screwing portion is formed from the open end of the inner cylinder portion 131 to the middle, but even if the female screw is formed over the entire axial direction of the inner cylinder portion 131. It may be formed only in the center of the inner cylinder portion 131. That is, in the present invention, the position of the female thread portion is set to an arbitrary position of the connector member.

Further, as shown in FIGS. 8A and 8B, a locking claw 135 as an engaging portion is formed to protrude inward in the radial direction on the inner peripheral surface of the outer cylinder portion 132 of the connector member 130. .. In this embodiment, the two locking claws 135 are arranged to face each other. A window portion 136 notched in a rectangular shape is bored above each locking claw 135. The outer peripheral surface of the connecting cylinder portion 111 can be confirmed from the outside through the window portion 136. The locking claw 135 allows movement in one axial direction (mounting direction) in which the connector member 130 is mounted with respect to the connecting cylinder portion 111, but the locking claw 135 is arranged in the annular groove 111b in the axial direction. It is configured to regulate the movement of the other (withdrawal direction). Specifically, the locking claw 135 has a downwardly inclined guide surface 135a and an upper vertical locking surface 135b.

With reference to FIG. 9, a form when the connector member 130 is attached to the connecting cylinder portion 111 will be described. As shown in FIG. 9A, when the connector member 130 is pressed downward in the axial direction with respect to the connecting cylinder portion 111 in mounting, the locking claw 135 is moved from the tip portion of the connecting cylinder portion 111 (from the annular groove 111b). When passing through the tip portion), the locking claw 135 abuts on the tip edge of the connecting cylinder portion 111, and only the outer cylinder portion 132 bends and deforms radially outward. At this time, the inclined guide surface 135a comes into contact with the tip edge of the connecting cylinder portion 111, so that the bending deformation is guided outward in the radial direction of the outer cylinder portion 132. Further, since the outer surface of the inner cylinder portion 131 is arranged to face the inner surface of the connecting cylinder portion 111, it is restricted that the inner cylinder portion 131 elastically bends and deforms outward in the radial direction. Then, as shown in FIG. 9B, when the locking claw 135 is further pressed downward in the axial direction in a bent and deformed state, the locking claw 135 gets over the tip of the connecting cylinder portion 111 and has an annular groove. Enter 111b. At the same time that the locking claw 135 reaches the annular groove 111b, the locking claw 135 elastically returns to its original shape and is arranged inside the annular groove 111b.

Next, the configuration of the tubular member 140 of the present embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is a schematic perspective view of the tubular member 140. 11 (a) to 11 (c) are a plan view, a front view, and an EE sectional view of the tubular member 140.

The tubular member 140 is a long hollow tube made of synthetic resin that opens on both sides in the axial direction and has a smooth inner peripheral surface that extends in the axial direction. Generally, the tubular member 140 is used when it is necessary to dispose of the connection target (for example, a device) and the joint body 100 at a predetermined distance. The length of the tubular member 140 is determined according to the predetermined distance. Further, the inner peripheral diameter of the tubular member 140 becomes smaller as it is separated from both openings in the axial direction. The inner diameter of the minimum diameter portion of the tubular member 140 is substantially equal to the outer diameter of the connecting cylinder portion 111. Further, at substantially the center of the tubular member 140 in the axial direction, the locking step portion 142 is formed by projecting the inner wall inward in the radial direction. The upper surface and the lower surface of the locking step portion 142 act to lock the connection target when the connection target to be inserted is elongated. A smooth bonded surface 141 to which the adhesive surface 111c of the connecting cylinder portion 111 adheres is defined on the inner peripheral surface of the tubular member 140. The bonded surface 111c and the surface to be bonded 141 are generally combined with each other and bonded by an adhesive. As described above, the tubular member 140 is not interpreted as a component of the connecting device, but is interpreted as a part of the device 11 (as the first connection target member) or as a joint for connecting to the device 11. You may.

Next, the configuration of the cover body 120 of the present embodiment will be described with reference to FIG. 12 (a) and 12 (b) are schematic perspective views of the cover body 120.

As shown in FIG. 12, the cover body 120 is made of a transparent or translucent synthetic resin, and is formed in a thin cylindrical shape having a C-shape in a plan (cross section) view. In other words, the cover body 120 is a thin strip-shaped body that curves while drawing an arc until both ends thereof are close to each other. The thin strip can be elastically deformed like a leaf spring. The cover body 120 is composed of a substantially cylindrical wall portion 121 cut along the axial direction. The wall portion 121 has a shape corresponding to the peripheral wall portion 113 of the joint main body 110. More specifically, the height of the wall portion 121 substantially coincides with the height of the peripheral wall portion 113, and the inner diameter of the wall portion 121 substantially coincides with the outer diameter of the peripheral wall portion 113. That is, the cover body 120 is configured to be fitted to the peripheral wall portion 113 of the joint body 110.

Further, the wall portion 121 of the cover body 120 is provided with a louver portion 122 extending to a predetermined region in order to form a through-hole region having a predetermined size. The louver portion 122 has a rectangular shape when unfolded in a plane, and is composed of a plurality of blades arranged side by side in the vertical direction. Further, the louver portion 122 is formed at two positions of the wall portion 121 at positions substantially facing each other. The position of the louver portion 122 corresponds to the position of the opening 114 of the peripheral wall portion 113, and the height and width of the louver portion 122 correspond to the height and width of the opening 114. That is, as shown in FIGS. 1 and 2, each louver portion 122 is configured to cover the entire opening 114 while the cover body 120 is attached to the joint body 110.

Further, the cut (over the axial direction) of the wall portion 121 of the cover body 120 is defined as the attachment / detachment opening 125. That is, the detachable opening 125 is divided in the circumferential direction of the cover body 120 and opens laterally. In other words, a part of the wall portion 121 in the circumferential direction is cut (or divided). In the original form of the cover body 120, the opening width of the detachable opening 125 is smaller than the outer diameter of the peripheral wall portion 113 of the joint body 110. Then, the removable opening 125 can be expanded by elastically deforming the wall portion 121 of the cover body 120. The detachable opening 125 can expand at least the peripheral wall portion 113 to a width that can be accepted from the side. In other words, the opening width of the detachable opening 125 in the expanded state is larger than the outer diameter of the peripheral wall portion 113 of the joint body 110. That is, the cover body 120 is detachable from the side with respect to the peripheral wall portion 113 due to its elasticity.

Subsequently, with reference to FIGS. 13 to 15, the connecting device 100 in which the connector member 130 is selectively mounted on the joint body 110 will be described. 13 (a) and 13 (b) are schematic perspective views of the connecting device 100. 14 (a) and 14 (b) are a front view and a side view of the connecting device 100. FIG. 15 is a cross-sectional view taken along the line FF of the connecting device 100.

The connector member 130 is rotatably attached to the tip of the connecting cylinder 111 of the joint body 110. The upstream opening of the inner cylinder portion 131 of the connector member 130 communicates with the internal space of the joint body 110. In a state where the connector member 130 is mounted on the connecting cylinder portion 111, the engaging portion (engaging claw 135) and the engaged portion (annular groove 111b) cooperate with each other to move the connector member 130 in the axial direction. It is regulated and the connector member 130 is allowed to move in the circumferential direction. In particular, when the connector member 130 tries to move downward in the axial direction (mounting direction), the upper wall portion 133 is locked to the tip edge of the connecting cylinder portion 111. On the other hand, when the connector member 130 tries to move upward in the axial direction (disengagement direction), the locking surface 135b of the locking claw 135 is locked to the upper wall surface of the annular groove 111b. As a result, the locking claw 135 is maintained in the annular groove 111b, and the relative movement of the connector member 130 with respect to the joint body 110 in the axial direction is restricted. On the other hand, since the locking claw 135 can freely slide in the annular groove 111b in the circumferential direction, the connector member 130 can freely rotate relative to the joint body 110. By rotating the connector member 130, the female threaded portion 134 can be freely screwed on or unscrewed from the male threaded portion 12, which is one of the connection targets.

Further, as shown in FIG. 15, the inner cylinder portion 131 of the connector member 130 enters the inside through the opening at the tip of the connection cylinder portion 111, and the outer cylinder portion 132 is located outside the connection cylinder portion 111. That is, the inner cylinder portion 131 is arranged to face the inner peripheral surface of the connecting cylinder portion 111, and the outer cylinder portion 132 is arranged to face the outer peripheral surface of the connecting cylinder portion 111. Further, the inner cylinder portion 131 extends deeper than the outer cylinder portion 132 of the connecting cylinder portion 111. In this configuration, the connecting cylinder portion 111 and the connector member 130 have the locking claws 135 arranged in the annular groove 111b and are held without interacting with each other in the radial direction. Therefore, the radial forces applied to each have little effect on each other. Specifically, even if the connector member 130 is screwed and tightened to the male screw portion 12 (screwed portion) to be connected, the members are independent of each other, so that the connector member 130 is radial to the connecting cylinder portion 111. The action of force is suppressed. Further, the inner cylinder portion 131 and the outer cylinder portion 132 are arranged so as to face each other in close contact with or in sliding contact with the inner peripheral surface and the outer peripheral surface of the peripheral wall of the connecting cylinder portion 130, respectively. As a result, when some radial force is applied to the outer cylinder portion 132 from the outside, even if the outer cylinder portion 132 bends and deforms in the radial direction and is distorted, the connecting cylinder portion 111 and the inner cylinder portion 131 engage with each other. By doing so, it is possible to prevent the connecting cylinder portion 111 and the inner cylinder portion 131 from bending and deforming. Since the inner cylinder portion 131 extends deeper into the connection cylinder portion 111 than the outer cylinder portion 132, the area in which the inner cylinder portion 131 and the peripheral wall of the connection cylinder portion 111 can be engaged becomes larger, and the inner cylinder portion 131 becomes stronger. Deformation of the connection cylinder portion 111 is suppressed. On the other hand, when some radial force is applied to the inner cylinder portion 131 from the inside, the connection cylinder portion 111 and the outer cylinder portion 132 engage with each other, so that the connection cylinder portion 111 and the outer cylinder portion 132 are bent and deformed. Is prevented. That is, in the connecting device 100 in which the connector member 130 is mounted on the joint body 100, the inner cylinder portion 131 and the outer cylinder portion 132 cooperate to support or lock the peripheral wall of the connecting cylinder portion 111 from the radial direction. The bending deformation of the peripheral wall of the connecting cylinder portion 111 is suppressed.

Subsequently, with reference to FIGS. 16 to 18, the connecting device 100 in which the tubular member 140 is selectively attached to the joint body 110 will be described. 16 (a) and 16 (b) are schematic perspective views of the connecting device 100. 17 (a) and 17 (b) are a front view and a side view of the connecting device 100. FIG. 18 is a cross-sectional view taken along the line GG of the connecting device 100.

The tubular member 140 is adhesively fixed to the tip of the connecting cylinder 111 of the joint body 110 at the downstream end thereof. Further, the upstream end of the tubular member 140 can be connected to another connection target (joint 13 in this embodiment). Specifically, in a state where the tubular member 140 is extrapolated to the connecting cylinder portion 111, the adhesive surface 111c on the outer peripheral surface of the connecting cylinder portion 111 and the bonded surface 141 on the inner peripheral surface of the tubular member 140 are adhered by the adhesive 143. It is glued. Then, as shown in FIG. 18, since the inner space of the tubular member 140 is tapered, the tip portion of the connecting cylinder portion 111 is the tubular member 140 in a state where the connecting cylinder portion 111 is inserted into the tubular member 140. It is fitted to the inner peripheral surface of the surface and is preferentially bonded and fixed. At the time of bonding, the adhesive 143 wraps around in the annular groove 111b, so that stronger bonding and fixing between the members is possible. Further, since it is not necessary to apply the adhesive 143 over the entire axial direction of the connecting cylinder portion 111, the amount of the adhesive used can be effectively reduced and the time required for the solidification of the adhesive can be shortened. Can be done. However, the present invention is not limited to the embodiment, and the adhesive may be applied to the back side of the annular groove 111b of the connecting cylinder portion 111, or the adhesive material may be applied only to the back side. May be good. In the present embodiment, the upstream end of the tubular member 140 is connected to the member to be connected by the adhesive means, but it may be connected by other means such as a fitting means or a screwing means.

That is, the joint body 110 of the present embodiment functions as an adhesive joint before the connector member 130 is attached, and functions as a union joint when the connector member 130 is attached. Then, when the tubular member 140 is adhered to the joint body 110, the connecting means of the tubular member 140 can be used. As described above, the connecting device 100 of the present embodiment can exhibit high versatility.

Subsequently, with reference to FIGS. 19 to 21, the configuration of the first device installation structure 10 for indirectly draining the drain drainage from the device 11 to the drain pipe 15 via the connecting device 100 of the present embodiment will be described. do. In the first device installation structure 10, the connector member 130 of the connecting device 100 is selectively attached to the joint body 100. FIG. 19 is an overall view schematically showing the device installation structure 10. FIG. 20 is an exploded perspective view of the device installation structure 10. FIG. 21 is a partial cross-sectional view of the equipment installation structure 10.

The device installation structure 10 includes a device 11, a connecting device 100 connected upstream to the device 11, and a drain pipe 15 connected downstream of the connecting device 100. As shown in FIG. 19, in the device installation structure 10, the device 11 is fixed to the wall surface of the building. A male screw portion 12 extends from the lower surface of the device 11 as a cylindrical discharge portion for draining drain drainage (see FIG. 20). The male screw portion 12 has a discharge port that opens downward. A drainage pipe 15 is installed downstream of the device 11. The drainage pipe 15 is composed of a sub-drainage pipe extending vertically and horizontally below the device 11 and a main drainage pipe extending vertically and vertically from the sub-drainage pipe to the drainage facility. That is, in the device installation structure 10, a drainage route for indirectly draining drainage drainage from upstream to downstream is formed between the device 11 and the drainage pipe 15.

As shown in FIG. 20, the connector member 130 mounted on the connecting device 100 is screwed onto the male threaded portion 12, and the joint body 110 is connected to the male threaded portion 12 of the device 11 via the connector member 130. That is, the tip of the female threaded portion 134 of the connector member 130 is directed to the tip of the male threaded portion 12, and the outer peripheral surface of the outer cylinder portion 132 of the connector member 130 is operated to make the connector member 130 relative to the joint body 110. By rotating, the female threaded portion 134 and the male threaded portion 12 are screwed together. Then, the upper surface of the upper wall portion 133 is tightened until it comes into pressure contact with the lower surface of the device 11. Due to the structure of the connecting device 100, no radial force is applied to the joint body 110 when tightening. Further, since the joint body 110 can freely rotate with respect to the connector member 130 (or the device 11) while the connecting device 100 is connected to the device 11, its orientation can be arbitrarily changed. As a result, maintainability can be improved, such as arranging the louver portion 122 in the front surface.

As shown in FIG. 21, the female threaded portion 134 of the connector member 130 and the male threaded portion 12 of the device 11 are firmly screwed together. As a result, the upstream connection port 111a of the joint body 110 and the discharge port of the device 11 communicate with each other, and the connection tube portion 111 is connected to the male screw portion 12 of the device 11 so that drainage can flow in. Then, two openings 114 of the joint body 110 are opened to the front surface and the back surface, and the drainage path is opened to the external space through the openings 114. At this time, the water flow cylinder portion 112 extends toward the receiving port 116a in the drainage port space 115, the outlet 112b and the receiving port 116a are separated from each other at a close distance from each other, and the outlet 112b is exposed from the opening 114. .. In other words, the opening 114 opens between the outlet 112b and the socket 116a. Further, the cover body 120 is attached to the joint body 110 so that the inner surface of the wall portion 121 of the cover body 120 comes into contact with the outer surface of the peripheral wall portion 113 of the joint body 110.

Then, the joint body 110 is connected to the drain pipe 15 downstream of the joint body 110. More specifically, as shown in FIG. 21, the sub-drainage pipe of the drainage pipe 15 is inserted into the downstream connection port 117a extending below the drainage portion 117 and connected to each other. Therefore, in the device installation structure 10, the drain drainage generated from the device 11 is indirectly drained to the drain pipe 15 (drainage facility) via the joint body 110.

In the equipment installation structure 10, when the backflow drainage rises upstream through the discharge portion 107, the receiving portion 116 is filled with the drainage and the drainage overflows from the receiving port 116a through the opening 114. At this time, the drainage that has flowed back through the through hole 124 of the louver portion 122 that covers the opening 114 is discharged to the outside. The drainage passes in order from the lowermost through hole 124 according to the magnitude of the water pressure of the backflow drainage. In the case of backflow drainage in which the water pressure is relatively weak, all the drainage can be discharged from the through hole 124 in the lowermost stage. In such a case, the lower edge of the lowermost through hole 124 and the opening edge of the receiving port 114 are at the same height, and the through hole 124 extends over the entire width of the opening 114, so that the cover is covered. The decrease in the amount of water discharged due to the body 120 does not occur. On the other hand, in the case of backflow drainage in which the water pressure is relatively strong, the water level rises beyond the bottom through hole 124, but the drainage can be discharged from the bottom through the plurality of through holes 124. Since these through holes 124 are arranged side by side over the entire height direction of the opening 114, a desired amount of water discharged is sufficiently maintained.

Next, with reference to FIGS. 22 to 24, the configuration of the second device installation structure 10'for indirectly draining the drain drainage from the device 11 to the drain pipe 15 via the connecting device 100 of the present embodiment will be described. do. In the second device installation structure 10', the tubular member 140 of the connecting device 100 is selectively attached to the joint body 100. FIG. 22 is an overall view schematically showing the device installation structure 10'. FIG. 23 is an exploded perspective view of the device installation structure 10'. FIG. 24 is a partial cross-sectional view of the equipment installation structure 10'.

As shown in FIG. 22, a joint 13 is screwed onto the male threaded portion 12, and a connecting device 100 is connected to the male threaded portion 12 of the device 11 via the joint 13. More specifically, as shown in FIG. 23, the tip of the joint 13 is fitted and adhered to the tubular member 140 bonded to the connection cylinder portion 111 of the joint body 110, so that the connection cylinder portion 111 drains water. It is connected to the device 11 so that it can flow in. As shown in FIG. 24, the tip portion of the joint 13 is inserted into the upper portion of the tubular member 140, and the outer peripheral surface of the joint 13 is adhered to the tapered inner peripheral surface of the tubular member 140 with an adhesive 143. On the other hand, the connecting cylinder portion 111 is inserted into the lower portion of the tubular member 140, and the adhesive surface 111c of the connecting cylinder portion 111 and the bonded surface 141 of the tubular member 140 are adhered with the adhesive 143. As a result, a water passage extending in the axial direction from the discharge port of the device 11 to the drainage portion 117 of the joint body 110 is formed. That is, in the device installation structure 10', the drain drainage generated from the device 11 is indirectly drained to the drain pipe 15 (drainage facility) via the joint body 110 arranged at a position separated from the device 11.

FIG. 25 shows another usage example of the connecting device 100. That is, in the connecting device 100, the tubular member 140 may be omitted, and the connecting tubular portion 111 may be adhered to the joint 13 that can be screwed to the male screw portion 12 of the device 11. In this case, the joint 13 can be interpreted as the first connection target member, and the male screw portion 12 can be interpreted as the second connection target member. Alternatively, the joint 13 itself may be interpreted as synonymous with the tubular member of the present invention. Depending on the situation, one of the connector member 130 and the joint 13 may be selected and mounted on the joint body 110. Further, in FIG. 25, the joint 13 is inserted into the connecting cylinder portion 111 and adhered. That is, the connection cylinder portion 111 may have a smooth adhesive surface on the inner peripheral surface in addition to the outer peripheral surface.

Hereinafter, the operation and effect of the connecting device 100 according to the embodiment of the present invention will be described.

According to the connection device 100 of the present embodiment, when the tubular member 140 is selected to construct the device installation structure 10', the connector member 130 is not selectively attached to the connection cylinder portion 111, but instead of the connection cylinder portion 111. The adhesive surface 111c of 111 and the adhered surface 141 of the tubular member 140 are adhered by an adhesive means, and the tubular member 140 and the connecting cylinder portion 111 are interconnected. On the other hand, when the connector member 120 is selected to construct the device installation structure 10, the tubular member 140 is not selectively adhered to the connecting cylinder portion 111, but instead the locking claw 135 (engagement portion) and the annular groove 111b. The engagement relationship of the (engaged portion) restricts the axial movement of the connector member 130 with respect to the connection cylinder portion 111, and allows the connector member 130 to move in the circumferential direction with respect to the connection cylinder portion 111. The member 130 is attached to the connector portion 111. That is, while holding the connector member 130 in the connection cylinder portion 111, the female screw portion 134 (screwed portion) of the connector member 130 is addressed to the male screw portion 12 (threaded portion) of the device 11 to rotate the connector member 130. By letting them screw together, they can be screwed together. Therefore, the connecting device 100 of the present embodiment can be directly and easily connected to the male threaded portion 12 of the device 11 by using the connector member 130. Therefore, in the connection device 100 of the present embodiment, the tubular member 140 and the connector member 130 can be appropriately selected according to the connection means with the connection target, and the connection device 100 has higher versatility.
