  However, in the pipe joint disclosed in Patent Document 1, each stopper is attached to each pipe while maintaining the state in which the ends of the pipes to be connected are inserted into the first opening and the second opening of the main body, respectively. It must be simultaneously fitted and removed from the outer circumference of the body. For this reason, it is difficult to maintain the state in which the tubular body is inserted into each of the first opening and the second opening of the main body depending on the situation at the work site, etc., or each stopper is attached to the outer peripheral surface of each tubular body. In some cases, it is difficult to connect the pipes, for example, it is difficult to fit them together. If it is difficult to connect the pipe bodies, the fitting of the stopper portions to the outer peripheral surfaces of the pipe bodies may be insufficient, and water may leak.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the pipe joint which can perform the connection operation | work and the isolation | separation operation | work of a pipe body easily and reliably.

The pipe joint of the present invention is
A first opening into which an end of the first tubular body can be inserted;
A second opening into which the end of the second tubular body can be inserted;
A hollow portion communicating the first opening and the second opening;
A first hole portion penetrating in the vicinity of the first opening and inserting an end of the first tube into the first opening; a portion of the end of the first tube appears;
And a second hole portion that penetrates in the vicinity of the second opening, and when the end of the second tube is inserted into the second opening, a part of the end of the second tube appears.
A body having an outer peripheral wall formed with
A first stopper portion that is inserted into the first hole portion and prevents the end portion of the first tubular body from coming off from the first opening;

The first stopper portion and the second stopper portion are connected so as to face in the same direction, and the first stopper portion is inserted into the second hole portion with the second stopper portion inserted into the second hole portion. A connecting part that bends so that it can be inserted into and removed from the part,
A fastener having
It is characterized by having.

  In this pipe joint, the first stopper portion can be inserted into and removed from the first hole portion in a state where the second stopper portion is inserted into the second hole portion by bending the connecting portion. For this reason, this pipe joint can connect a 1st pipe body and a 2nd pipe body as follows. First, the end of the second tubular body is inserted into the second opening. And a 2nd stopper part is inserted in a 2nd hole part. Thus, the end of the second tubular body inserted into the second opening can be easily and reliably connected to the state in which the end of the second tubular body is prevented from coming off from the second opening. In this state, the pipe joint can be in a state where the connecting portion is bent and the first stopper portion is not inserted into the first hole portion. Thereafter, the end of the first tubular body is inserted into the first opening of the main body. And a 1st stopper part is inserted in a 1st hole. Accordingly, the end of the first tubular body inserted into the first opening can be easily and reliably connected to the state in which the end of the first tubular body is prevented from coming off from the first opening, and the connection work of the first tubular body and the second tubular body. Can be completed.

  Thus, in this pipe joint, it is not necessary to insert each of the first stopper portion and the second stopper portion into the first hole portion and the second hole portion at the same time, and the second stopper portion is inserted into the second hole portion. After connecting the end of the second tube to the second opening, the end of the first tube is inserted into the first opening and the first stopper is inserted into the first hole. The one stopper part and the second stopper part can be easily and reliably inserted into the first hole part and the second hole part one by one. For this reason, this pipe joint can easily and reliably connect the end of the first tube and the end of the second tube to the first opening and the second opening.

  Moreover, this pipe joint can isolate | separate the 1st pipe body and the 2nd pipe body which were connected as follows. First, only the first stopper portion is extracted from the first hole portion while bending the connecting portion. Thereby, the end portion of the first tubular body inserted into the first opening can be pulled out from the first opening. For this reason, this pipe joint can extract a 2nd stopper part from a 2nd hole part in the state in which the edge part of the 1st pipe body is not inserted in the 1st opening part. And the end part of the 2nd tubular body is pulled out from the 2nd opening, and separation work of the connected 1st tubular body and the 2nd tubular body can be completed. Moreover, this pipe joint can also complete the separation operation in the same manner by a procedure in which only the second stopper portion is first extracted from the second hole portion and then the first stopper portion is extracted from the first hole portion.

  Thus, this pipe joint does not require the first stopper part and the second stopper part to be simultaneously extracted from the first hole part and the second hole part, respectively, and the first stopper part is extracted from the first hole part. After the end portion of the first tubular body is extracted from the opening, the second stopper portion can be extracted from the second hole portion, and the end of the second tubular body can be extracted from the second opening portion. Or, conversely, after the second stopper portion is extracted from the second hole portion and the end portion of the second tubular body is extracted from the second opening portion, the first stopper portion is extracted from the first hole portion and then from the first opening portion. The end portion of the first tubular body can be pulled out. For this reason, this pipe joint can easily separate the end of the first tube and the end of the second tube from the first opening and the second opening.

  Therefore, the pipe joint of the present invention can easily and reliably perform the connecting operation and the separating operation of the pipe body.

  A preferred embodiment of the present invention will be described.

  In the present invention, the outer peripheral wall holds the distal end portion of the first stopper portion in contact with the outer peripheral surface adjacent to the first hole portion in a state where the second stopper portion is inserted into the second hole portion. It may have an abutting part. In this case, when connecting the first tube body and the second tube body, this pipe joint inserts the end portion of the second tube body into the second opening and inserts the second stopper portion into the second hole portion. In this state, that is, in a state where the second tubular body is connected to the second opening while preventing the second tubular body from coming off, the tip of the first stopper portion can be held in contact with the contact portion. For this reason, after that, the end of the first tubular body can be easily inserted into the first opening. In addition, this pipe joint can easily insert the first stopper portion having the tip portion held in contact with the contact portion into the first hole portion. For this reason, this pipe joint can perform connection work easily and reliably.

  In the present invention, the contact portion may have a guide portion that guides the distal end portion of the first stopper portion in the other first hole portion. In this case, the pipe joint can be easily and surely inserted into the first hole portion by moving the first stopper portion, which has the tip portion held in contact with the contact portion, along the guide portion. For this reason, this pipe joint can perform connection work easily and reliably.

  In the present invention, the connecting portion may have a bent portion that is bent so as to protrude in a direction opposite to a direction in which the first stopper portion and the second stopper portion are facing. In this case, a contact portion is formed on the outer peripheral surface on the first opening portion side from the first hole portion, and when the first stopper portion whose tip portion is in contact with the contact portion is inserted into the first hole portion, The bent portion is bent, and the first stopper portion can be easily inserted into the first hole portion. Further, when the first stopper portion is pulled out from the first hole portion, the bent portion is bent, and the first stopper portion can be easily pulled out from the first hole portion.

  In the present invention, the outer peripheral wall has a groove portion into which the connecting portion is fitted in a state where the first stopper portion is inserted into the first hole portion and the second stopper portion is inserted into the second hole portion. Can do. In this case, when each of the first stopper portion and the second stopper portion is inserted into the first hole portion and the second hole portion, the connecting portion fits into the groove portion, and the state can be easily visually recognized from one direction. For this reason, this pipe joint confirms the degree of fitting of the connecting portion into the groove portion, and whether or not the first stopper portion and the second stopper portion are properly inserted into the first hole portion and the second hole portion, That is, it can be determined whether or not the end of the first tubular body inserted into the first opening and the end of the second tubular body inserted into the second opening are securely retained.

  In the present invention, the groove portion may have a depth that can completely accommodate the connecting portion. In this case, in a state where the pipe joint connects the first tube body and the second tube body, the connecting portion does not protrude from the groove portion. For this reason, when this pipe joint is other than the separation work (such as when the stored items in the cabinet are taken in and out), the first stopper part or the second stopper part is unexpectedly caught by the first stopper part or the second stopper part. It can be prevented from being extracted from the part. Further, if the connecting part protrudes even slightly from the upper end of the groove part, it is clear that the first stopper part and / or the second stopper part is not properly inserted into the first hole part and / or the second hole part. Can be recognized. For this reason, the first stopper portion and the second stopper portion are appropriately inserted into the first hole portion and the second hole portion, and inserted into the end portion and the second opening portion of the first tubular body inserted into the first opening portion. It can be determined whether or not the end portion of the second tubular body is securely retained.

  Next, an embodiment embodying the pipe joint of the present invention will be described with reference to the drawings.

<Example>
As shown in FIG. 1, the pipe joint 1 of the embodiment includes a water discharge pipe 4 (first pipe) and a shower hose 5 (second pipe) of a faucet fitting 3 attached to a top plate 2 of a cabinet such as a kitchen. Body) in the cabinet. The water discharge pipe 4 is connected to an outflow port of a not-shown hot water / water mixing part housed in the faucet fitting body 6 and passes through the faucet fitting body 6 and hangs down in the cabinet. The end is connected to the pipe joint 1. The shower hose 5 has a downstream end connected to the shower head 7 of the faucet fitting 3, passes through the faucet fitting main body 6 and extends into the cabinet, and an upstream end is connected to the pipe joint 1. Yes. The shower head unit 7 can be detached from the faucet fitting main body 6. In this faucet fitting 3, the shower head part 7 can be removed from the faucet fitting main body 6 and the shower hose 5 can be pulled out.

  As shown in FIGS. 2 to 4, the pipe joint 1 includes a main body 10 and a fastener 50. The main body 10 has a substantially cylindrical outer peripheral wall 11 having a plurality of types of outer diameters and inner diameters. The outer peripheral wall 11 has a plurality of ribs 12 extending in the axial direction and the circumferential direction on the outer peripheral surface. The outer peripheral wall 11 forms a first opening 13 and a second opening 14 that are open at both ends. The first opening 13 and the second opening 14 are substantially circular. The first opening 13 is formed to have a smaller opening area than the second opening 14. The first opening 13 has a diameter slightly larger than the outer diameter of the first to third flanges 4A, 4B, 4C provided at the downstream end of the water discharge pipe 4. The 2nd opening part 14 has a diameter slightly larger than the external shape of the 1st-3rd collar part 5A, 5B, 5C provided in the upstream end part of the shower hose 5. FIG. The outer peripheral wall 11 has a hollow portion 15 that communicates the first opening 13 and the second opening 14 inside. The hollow portion 15 accommodates the downstream end portion of the water discharge pipe 4 and the upstream end portion of the shower hose 5, while the central portion forms a flow path.

  The outer peripheral wall 11 forms a first hole 16 and a second hole 17. The first hole 16 penetrates the outer peripheral wall 11 near the first opening 13, and the second hole 17 penetrates the outer peripheral wall 11 near the second opening 14. The first hole 16 and the second hole 17 are formed in a slit shape extending in a direction perpendicular to the axial direction of the outer peripheral wall 11. The first hole 16 and the second hole 17 are open in the same direction. The center in the circumferential direction of the first hole portion 16 and the center in the circumferential direction of the second hole portion 17 are located on the same straight line extending in the axial direction of the outer peripheral wall 11. The first hole portion 16 is formed to have a smaller width in the circumferential direction than the second hole portion 17. The first hole 16 and the second hole 17 have the same width in the axial direction of the outer peripheral wall 11. When the end of the water discharge pipe 4 is inserted into the first opening 13, a part of the end of the water discharge pipe 4 appears in the first hole 16. In addition, when the end portion of the shower hose 5 is inserted into the second opening portion 14, the second hole portion 17 shows a part of the end portion of the shower hose 5.

  The outer peripheral wall 11 is an encircling wall portion 16A formed so that a first stopper portion 51 and a second stopper portion 52 of a fastener 50 described later are fitted around the first hole portion 16 and the second hole portion 17, respectively. 17A. The surrounding wall portion 16 </ b> A has a height that is substantially flush with the back surface of the first stopper portion 51 when the first stopper portion 51 is inserted into the first hole portion 16. The surrounding wall 17A also has a height such that the back surface of the second stopper portion 52 is substantially flush with the second stopper portion 52 when the second stopper portion 52 is inserted into the second hole portion 17.

  The outer peripheral wall 11 has a contact portion 18 on the outer peripheral surface between the first hole portion 16 and the first opening portion 13. The abutting portion 18 is formed in parallel in the circumferential direction so that the tip ends of a pair of first claw portions 51B of a first stopper portion 51 of the fastener 50 to be described later abut on each other. It is a belt-like plane extending in the direction of the first opening 13 from the outer edge of the portion 16 on the first opening 13 side.

  The abutting portions 18 are arranged in parallel and located outside the distal end portions of the first claw portions 51B in a state where the distal end portions of the pair of first claw portions 51B of the first stopper portion 51 are in contact with each other. Each of the first claw portions 51 </ b> B has two guide portions 19 that guide the first claw portions 51 </ b> B to the first hole portion 16. These guide portions 19 protrude from the contact portion 18 and extend from the outer edge of the first hole portion 16 on the first opening portion 13 side in the direction of the first opening portion 13.

  The outer peripheral wall 11 has the groove part 20 in which the connection part 53 of the fastener 50 mentioned later fits. The groove portion 20 is formed by two wall portions 21 that rise from the outer peripheral wall 11 and are arranged in parallel. These wall portions 21 are formed between the first hole portion 16 and the second hole portion 17 at an interval slightly wider than the width of the connecting portion 53. The groove portion 20 formed by these two wall portions 21 extends on a line connecting the circumferential center of the first hole portion 16 and the circumferential center of the second hole portion 17. When the connection part 53 fits in the groove part 20, the state can be easily visually recognized from one direction.

  The two wall portions 21 form a substantially semicircular convex portion 22 whose end on the first hole 16 side protrudes outward. The convex portion 22 has an outer shape that follows the shape of the bent portion 56 of the connecting portion 53 described later. These two wall portions 21 are fastened when the first stopper portion 51 and the second stopper portion 52 are inserted into the first hole portion 16 and the second hole portion 17 to connect the water discharge pipe 4 and the shower hose 5, respectively. It is formed so that the upper surface is located slightly outside the back surface of the connecting portion 53 of the tool 50. That is, the groove 20 is formed to a depth that can completely accommodate the connecting portion 53.

  The main body 10 has a hose insertion tube 30 connected to the central portion of the outer peripheral wall 11. The hose insertion tube 30 has a cylindrical shape penetrating in the same direction as the outer peripheral wall 11, and is arranged in parallel with the main body 10. The hose insertion tube 30 has an inner diameter through which the shower hose 5 can be inserted. The shower hose 5 extending from the faucet fitting body 6 into the cabinet is inserted into the hose insertion tube 30. As a result, the shower head portion 7 was removed from the faucet fitting body 6 and the shower hose 5 was pulled out. Conversely, the shower head portion 7 was attached to the faucet fitting body 6 while the shower hose 5 was pushed in. In this case, it is possible to prevent the shower hose 5 from being exposed in the cabinet.

  As shown in FIGS. 2 and 4, the fastener 50 includes a first stopper portion 51, a second stopper portion 52, and a connecting portion 53 that connects the first stopper portion 51 and the second stopper portion 52. Yes. The first stopper portion 51 has a first base portion 51A and a pair of first claw portions 51B extending in the same direction from both sides of the first base portion 51A.

  The inner surface of each first claw portion 51 </ b> B of the first stopper portion 51 and the front surface of the first base portion 51 </ b> A are formed as curved surfaces along the outer peripheral surface of the downstream end portion of the water discharge pipe 4. The dimension between the front-end | tip parts of each 1st nail | claw part 51B is formed slightly smaller than the outer diameter of the downstream end part of the water discharge pipe 4. As shown in FIG. For this reason, the first stopper portion 51 is provided with each first claw portion so that when the downstream end portion of the water discharge pipe 4 is fitted, the first claw portion 51B is easily elastically deformed in a direction in which the front end portion slightly opens. An incision 51C is formed obliquely from the inside of the portion where 51B is connected to the first base 51A toward the first base 51A.

  When the first stopper 51 is inserted into the first hole 16, the downstream end of the water discharge pipe 4 (first tube) inserted into the first opening 13 is the inner surface of each first claw 51B and the first base. It fits in the space formed between the front surface of 51A. As a result, the second flange 4B formed at the downstream end of the water discharge pipe 4 is locked to the first stopper 51, and the downstream end of the water discharge pipe 4 can be prevented from coming off from the first opening 13. (See FIGS. 7 and 9).

  51 A of 1st base parts have the 1st convex part 54 which protruded on the opposite surface to the part which the connection part 53 has connected. The first convex portion 54 can be used when an operator puts the first stopper portion 51 into the first hole portion 16 with a finger. Further, since the first convex portion 54 contacts the outer peripheral surface of the outer peripheral wall 11 when the first stopper portion 51 is inserted into the first hole portion 16, the first stopper portion 51 is pushed too much into the first hole portion 16. Absent.

  The second stopper portion 52 is formed to be slightly larger than the first stopper portion 51. The second stopper portion 52 includes a second base portion 52A and a pair of second claw portions 52B extending in the same direction from both sides of the second base portion 52A.

  The inner surface of each second claw portion 52B of the second stopper portion 52 and the front surface of the second base portion 52A are formed as curved surfaces along the outer peripheral surface of the upstream end portion of the shower hose 5. The dimension between the tip portions of the second claw portions 52B is slightly smaller than the outer diameter of the upstream end portion of the shower hose 5. For this reason, the second stopper portion 52 is provided with each second claw so that when the upstream end portion of the shower hose 5 is fitted, the second claw portion 52B is easily elastically deformed in a direction to slightly open between the distal end portions of the pair of second claw portions 52B. An incision 52C is formed obliquely from the inside of the portion where the portion 52B is connected to the second base 52A toward the second base 52A.

  When the second stopper portion 52 is inserted into the second hole portion 17, the upstream end portion of the shower hose 5 (second tube) inserted into the second opening portion 14 is the inner surface of each second claw portion 52B and the second base portion. It fits in the space formed between the front surface of 52A. As a result, the second flange 5B formed at the upstream end of the shower hose 5 is locked to the second stopper 52, and the upstream end of the shower hose 5 can be prevented from coming off from the second opening 14. (See FIGS. 6, 7 and 9).

  52 A of 2nd base parts have the 2nd convex part 55 which protruded on the opposite surface to the part which the connection part 53 has connected. Since the second convex portion 55 contacts the outer peripheral surface of the outer peripheral wall 11 when the second stopper portion 52 is inserted into the second hole portion 17, the second stopper portion 52 is not pushed too much into the second hole portion 17.

  The connecting portion 53 connects the first stopper portion 51 and the second stopper portion 52 so that the first stopper portion 51 and the second stopper portion 52 face the same direction. The connecting portion 53 has one end connected to the central portion on the back side of the first base portion 51 </ b> A of the first stopper portion 51, and the other end connected to the central portion on the back side of the second base portion 52 </ b> A of the second stopper portion 52. doing. The connection part 53 is flat form and can bend in the thickness direction. That is, as will be described later, since the connecting portion 53 of the fastener 50 bends in the thickness direction, the first stopper portion 51 is moved to the first hole portion with the second stopper portion 52 inserted into the second hole portion 17. 16 can be inserted and removed.

  The connecting portion 53 has a bent portion 56 bent at the end on the first stopper portion 51 side so as to protrude in a direction opposite to the direction in which the first stopper portion 51 and the second stopper portion 52 face. . The bent portion 56 is bent in a substantially semicircular arc shape. The connecting portion 53 forms a slit-like small hole 57 extending in the same direction as the extending direction of the connecting portion 53 from the curved surface of the end portion of the bent portion 56 on the second base 52A side to the plane.

  Next, using the pipe joint 1 having such a configuration, the connecting operation for connecting the water discharge pipe 4 and the shower hose 5 of the faucet fitting 3 and the connected water discharge pipe 4 and the shower hose 5 are separated. The separation work will be described.

<Consolidation work>
First, the upstream end of the shower hose 5 is pulled out to the front side of the cabinet, and the upstream end of the shower hose 5 is inserted into the second opening 14 of the main body 10 of the pipe joint 1. The shower hose 5 forms a first collar part 5A, a second collar part 5B, and a third collar part 5C in order from the distal end side of the upstream end part. The first flange 5 </ b> A is formed at the upstream end of the shower hose 5. In the shower hose 5, one O-ring P is externally fitted between the first flange portion 5A and the second flange portion 5B. The thickness of the second base 52A of the second stopper 52 and the thickness of each second claw 52B so that the second stopper 52 can be fitted between the second hook 5B and the third hook 5C. Slightly wide spacing.

  Then, as shown in FIGS. 5 and 6, the second stopper portion 52 is inserted into the second hole portion 17. The second stopper portion 52 inserted into the second hole portion 17 is elastically deformed in a direction in which the end portions of the pair of second claw portions 52B are slightly opened, and the second flange portion 5B and the third flange portion of the shower hose 5 are formed. The upstream end between 5C is fitted into a space formed between the inner surface of each second claw portion 52B and the front surface of the second base portion 52A. As a result, the second flange 5B formed at the upstream end of the shower hose 5 is engaged with the second stopper 52, and the upstream end of the shower hose 5 is connected to the second opening 14 in a prevented state. To do. When the second stopper portion 52 is inserted into the second hole portion 17, the back surface of the second stopper portion 52 and the upper surface of the surrounding wall portion 17 </ b> A formed around the second stopper portion 52 are substantially flush with each other.

  With the second stopper portion 52 inserted into the second hole portion 17, the connecting portion 53 of the fastener 50 bends, and the first stopper portion 51 has the tip portions of the pair of first claw portions 51 </ b> B at the contact portion 18. Abutted and held. That is, the fastener 50 can be in a state where the first stopper portion 51 is not inserted into the first hole portion 16 while the second stopper portion 52 is inserted into the second hole portion 17.

  In this state, the downstream end portion of the water discharge pipe 4 depending on the cabinet is inserted into the first opening 13 of the main body 10. At this time, without inserting the first stopper portion 51 into the first hole portion 16, the tip end portion of each first claw portion 51 </ b> B of the first stopper portion 51 can be held in contact with the contact portion 18, so that The downstream end of the water discharge pipe 4 can be easily inserted into the first opening 13. The water discharge pipe 4 is formed with a first collar part 4A, a second collar part 4B, and a third collar part 4C in order from the distal end side of the downstream end part at substantially equal intervals. In the water discharge pipe 4, two O-rings P and a cylindrical spacer S are externally fitted between the first collar part 4A and the second collar part 4B. There is a sufficiently wide space between the second flange portion 4B and the third flange portion 4C so that the first stopper portion 51 is fitted.

  Then, the operator places a finger on the first convex portion 54 of the first stopper portion 51 and pushes down the tip portions of the first claw portions 51B of the first stopper portion 51 so as to be inserted into the first hole portion 16. At this time, the distal end portion of each first claw portion 51 </ b> B moves downward along the guide portion 19. For this reason, the 1st stopper part 51 can be easily and reliably inserted in a 1st descending part. In addition, as shown in FIG. 7, when the first claw portions 51 </ b> B of the first stopper portion 51 are pushed down so as to be inserted into the first hole portion 16, the bent portion 56 is bent, so that the first stopper portion 51 is It can be easily inserted into the first hole 16.

  In this way, as shown in FIGS. 8 and 9, the first stopper portion 51 is inserted into the first hole portion 16. The first stopper portion 51 inserted into the first hole portion 16 is elastically deformed in a direction in which the tip portions of the pair of first claw portions 51B are slightly opened, and the second flange portion 4B and the third flange portion of the water discharge pipe 4 The upstream end between 4C is fitted into a space formed between the inner surface of each first claw portion 51B and the front surface of the first base portion 51A. As a result, the second flange 4B formed at the downstream end of the water discharge pipe 4 is engaged with the first stopper 51 and connected to the state where the upstream end of the water discharge pipe 4 is prevented from coming off from the first opening 13.
