【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the hose winder shown in FIG. 1, a winding drum 2 is rotatably supported between both side plates 1 a of a body frame 1 made of synthetic resin, and a body portion 2 a of the winding drum 2 is rotatably supported. The hose connection ports 3 and 4 are provided so as to project from the outer circumference and the shaft support portion on one side of the winding drum 2 respectively.

Although the main body frame 1 is integrally formed as shown in FIG. 1, it may be configured so that it can be divided from the center. The winding drum 2 supported by the main body frame 1 is integrally molded of synthetic resin, and a disk body 2b is formed at both ends of a hollow body portion 2a having a spiral groove for guiding the winding of the hose on the outer periphery. It is provided and configured, and is rotatably supported between both side plates 1a of the main body frame 1. The take-up drum 2 is rotatable by fitting a cylindrical support shaft portion 2 which is formed to project outward from both side surfaces to the outer periphery of a bearing body 7 which is fitted to the shaft support portions 5a and 5b of the both side plates 1a. Is pivotally supported.

Further, the hose connection port 4 provided so as to project from the shaft support portion 5a on one side of the drum 2 and the hose connection port 3 attached to the outer periphery of the body portion 2a are provided so as to pass through the inside of the body portion 2a. Communication is made through a water supply connection pipe 6. The water supply connecting pipe 6 is bent into an L-shape inside the winding drum 2, and one end thereof is inserted into the bearing hole 7a of the bearing body 7 to project outward from the side plate 1a, as shown in FIG. The other end is projected from the outer circumference of the winding drum 2 body 2a. Further, as described above, one end of the water supply connecting pipe 6 inserted into the bearing body 7 is rotatably fitted to the bearing body 7, and the other end of the water supply connecting pipe 6 is the winding drum 2 body portion 2a. It is fitted to the flat surface portion 2a 'formed on the outer periphery of the. The hose connection ports 3 and 4 provided at both ends of the water supply connection pipe 6 are each formed by bending a pipe member, and nuts 3a and 4a for retaining are screwed into a tip end portion which is a connection port of the hose. Mounting ports 3b and 4b are formed at the base end, and the mounting ports 3b and 4b are rotatably fitted to the ends of the water supply connecting pipe 6 through packings 8 and 9, respectively.

2 and 3 are enlarged cross-sectional views showing the mounting port 4b portion of one hose connection port 4. As shown in FIG. The attachment port 4b of the hose connection port 4 is fitted to the outer periphery of the end of the water supply communication pipe 6 which penetrates the bearing body 7 and projects outward through a packing 9 for maintaining watertightness. Further, a rotation stopper piece 4d is provided on the outer peripheral portion of the attachment opening 4b, and the rotation of the hose connection opening 4 is prohibited by hooking the rotation prevention piece 4d on the inner periphery of the bearing hole 7a. The water supply connection pipe 6 that rotates with the rotation of the winding drum 2 is configured to freely rotate inside the mounting port 4b of the hose connection port 4.

A fitting groove 4c is formed on the outer periphery of the above-mentioned mounting opening 4b, and the locking ring 10 is fitted from the outer periphery to the fitting groove 4c. The locking ring 10 is an E-shaped ring made of synthetic resin having appropriate elasticity, and as shown in FIG. 2, the locking pieces 10b are formed at three inner peripheral portions of the ring 10a formed in a substantially C shape. At the same time, the knob 11 is formed so as to protrude from the outer periphery of one end of the ring 10a. Then, the locking ring 10 is fitted in the fitting groove 4c of the mounting opening 4b, and each locking piece 10b penetrates the opening portion 4c 'of the fitting groove 4c so that the end portion of the water supply connecting pipe 6 is penetrated. It is locked in a locking groove 12 provided around the outer circumference. By locking each locking piece 10b of the locking ring 10 in the locking groove 12 as described above, the hose can be rotated freely between the water supply connecting pipe 6 and the mounting port 4. It is possible to prevent the connection port 4 from falling off the water supply communication pipe.

The gripping piece 11 of the locking ring 10 is formed by projecting to the outer peripheral portion of one end of the ring 10a and bending the tip end portion toward one side. Then, as shown in FIG. 4, by grasping the knob 11 and bending it so as to widen the diameter of the ring 10a, the engaging piece 10b which is engaged in the engaging groove 12 is disengaged as described above. The stop ring 10 can be removed. When the locking ring 10 is removed, the hose connection port 4 can be freely removed from the end of the water supply connection pipe 6. The other hose connection port 3 provided on the body portion 2a of the winding drum 2 is attached so as to rotate with respect to the end portion of the water supply communication pipe 6, but the locking ring and the fitting portion thereof are the same as those described above. The configuration is exactly the same as that described above, and the description thereof is omitted.

According to the hose winder configured as described above, the hose connection ports 3 and 4 are removed when connecting the hose to the hose connection ports 3 and 4 and when replacing the packings 8 and 9, for example. When the need arises, the locking ring 10 can be easily removed by holding the knob 11 as described above, which makes it easy to attach and detach the hose connection ports 3 and 4 without using tools. Can be done.

In the above-described embodiment, the hose connection ports 3 and 4 are fitted by fitting the mounting ports 3b and 4b of the hose connection ports 3 and 4 to the outer circumference of the end port of the water supply communication pipe 6. Although it is attached to the envelope tube 6, the above-mentioned fitting relationship is configured so that the attachment port of the hose connection port is fitted to the inner circumference of the end port of the water supply communication pipe, contrary to the above embodiment. You can do it. In this case, the locking ring will be fitted from the outer periphery of the end of the water supply communication pipe.
