[Industrial applications]

 The present invention relates to a hose reel for winding a hose used for watering a garden or washing a car.

[0002]

[Prior Art]

 As a conventional hose reel of this type, one having a structure shown in FIGS. 3 and 4, for example, is known. That is, shafts 3 and 4 are integrally provided at the left and right ends of the resin reel drum 2 which is also supported by a resin frame, and these shafts 3 and 4 are rotatably supported by the frame 1. ing. A crank-shaped handle 5 is connected to one shaft 4, and the reel drum 2 is rotated by rotating the handle 5. The other shaft 3 of the shafts 3 and 4 is formed in a hollow elbow shape and also serves as a water supply pipe 6. One end of the water supply pipe 6 is an O-ring on a water reception pipe 7 fixed to the frame 1. It is rotatably connected via 8. The shaft 3 also serving as the water supply pipe 6 is previously formed integrally with a disk-shaped drum cover 9, and the drum cover 9 is fixed to one end surface of the reel drum 2 by a screw 10. Further, the drum cover 9 is reinforced by a plurality of ribs 11.

An elbow pipe 12, which is a connecting pipe, is connected to the other end of the water supply pipe 6, and the water supply pipe 6 and the elbow pipe 12 are tightened by a metal tightening band 14 to prevent their removal. Has been applied. The elbow pipe 12 protrudes to the outer peripheral portion through the hole 15 formed in the reel drum 2 and extends in a direction substantially orthogonal to the shaft 3, that is, in a winding direction of a hose (not shown). have. The extension part 13 of the elbow pipe 12 is provided with a tightening nut 16 for tightening the base end part of the hose connected to the extension part 13 so as not to come off. It is screwed. Therefore, if a hose (not shown) connected to a faucet such as a water tap is connected to the water receiving pipe 7 to supply water, water will pass from the water receiving pipe 7 through the water feeding pipe 6 and the elbow pipe 12 and connect to the elbow pipe 12. It is discharged from the tip of the hose.

The hose connected to the elbow pipe 12 has a step between the end portion of the elbow pipe 12 and the outer peripheral portion of the reel drum 2 when wound around the reel drum 2. Is easily crushed, and when it is extended from the reel drum 2, the connecting portion with the elbow pipe 12 is easily bent due to the swinging and pulling of the hose. For this reason, in the hose reel, a coil spring having a diameter slightly larger than the opening diameter of the extension 13 is fitted in the extension 13 of the elbow pipe 12 in advance. In some cases, the end of the hose is slightly extended from the extension 13 to prevent the hose from being crushed or bent at the connecting portion.

[0005]

[Problems to be solved by the device]

 However, in such a hose reel, a coil spring, which is a separate member, is required to avoid bending of the hose, so the number of parts increases, which is an obstacle to lowering the price of the hose reel. .. Moreover, when the coil spring is fitted into the elbow pipe 12 at the time of manufacturing, the coil spring 20 must be inserted while being distorted in the radial direction, and the mounting workability is poor, which is also a factor of increasing the manufacturing cost. Was there.

The present invention has been made in view of such conventional problems, and provides a hose reel capable of preventing the hose from being crushed or bent at a connecting portion with a connecting pipe without providing a separate member. The purpose is to do.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, according to the present invention, a water pipe is formed on a shaft that rotatably supports a reel drum, and a resin-made connecting pipe communicating with the water pipe penetrates the outer periphery of the reel drum. In the hose reel, the connection pipe extends in the winding direction of the hose wound around the reel drum, and the hose base end portion is externally inserted. A plurality of cutouts are provided alternately along the longitudinal direction on the entire circumference on the tip side of the projecting portion.

[0008]

[Action]

 In the above structure, the extension portion of the connection pipe is flexible because a plurality of notches are provided alternately along the longitudinal direction on the entire circumference on the distal end side, and the extension portion of the connection pipe is based on the hose. If you try to bend it at the end side, that is, at the connection part with the connection pipe, a force in the direction intersecting the longitudinal direction is applied to the tip side of the flexible extension part, so the tip of the extension part The side is bent appropriately. Therefore, the connecting portion of the hose is also bent together with the tip end side of the extending portion.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. However, the same parts as those of the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted.

That is, as shown in FIG. 2, a socket portion 23 having a large diameter is integrally formed at the other end of the water supply pipe 22 which is integrally formed with the drum cover 9 and also serves as the shaft 3. The socket portion 23 is formed with a pair of fitting grooves 24 that penetrate the inner and outer peripheral surfaces of the socket portion 23 so as to face each other.

A ring groove 27, in which an O-ring 26 is mounted, is formed on the outer periphery of one end of an elbow pipe 25, which is a resin-made connecting pipe that is inserted and fitted in the socket portion 23 of the water supply pipe 22. A circumferential groove 28 is formed along the entire circumference side by side, and when the elbow pipe 25 is inserted into the socket portion 23 until the flange portion 29 on the elbow pipe 25 side comes into contact with the opening end surface of the socket portion 23, the socket The fitting groove 24 on the portion 23 side and the circumferential groove 28 on the elbow pipe 25 side are aligned with each other. Then, after inserting one end of the elbow pipe 25 into the socket portion 23 of the water supply pipe 22 as described above and attaching the snap ring 30 to the outer periphery of the socket portion 23, the socket portion 23 and the elbow pipe 25 are connected to each other. The elbow pipe 25 is rotatably connected to the water supply pipe 22 with the shaft center of the socket 23 as the center of rotation.

On the other hand, the elbow pipe 25 is a bellows-shaped member having an elbow shape but having a certain degree of flexibility, and as shown in FIG. 1, the elbow pipe 25 passes through a hole 15 formed in the reel drum 2 and has an outer peripheral portion. It has an extending portion 31 which protrudes and extends in a direction substantially perpendicular to the shaft 3, that is, in a winding direction of the hose 18 described later. A taper portion 32 and a male screw portion 33 for preventing slipping out are formed in the middle of the extending portion 31. The male screw portion 33 has a hose 18 externally inserted in the taper portion 32. A tightening nut 34 for tightening the base end portion to the taper portion 32 is screwed. Further, the extending portion 31 is formed to have a small diameter from the taper portion 32 to the tip so that the hose 18 can be fitted into the hose 18, and a plurality of cutouts are formed on the entire circumference thereof in a staggered manner along the longitudinal direction. The notch groove 35 is formed.

In the present embodiment having the above-described structure, when the hose 18 is wound on the reel drum 2, there is a step between the end of the elbow pipe 25 and the outer peripheral surface of the reel drum 2. A force in a direction intersecting the longitudinal direction is applied to the tip end side of the extending portion 31. At this time, since a plurality of cutout grooves 35 are provided alternately along the longitudinal direction on the entire circumference on the distal end side of the extension portion 31 of the elbow pipe 25, the elbow pipe 25 has flexibility and the extension portion 31 is provided. The tip end side of 31 is bent appropriately following the hose 18 to be wound. Therefore, it is possible to prevent the hose 18 wound around the reel drum 2 from crushing the connection portion with the elbow pipe 25.

On the other hand, when the hose 18 is extended from the reel drum 2 and the hose 18 is swung or pulled in a direction different from the extending direction of the extending portion 31 of the elbow pipe 25, a bellows shape is formed. The elbow pipe 25 having a certain degree of flexibility bends in accordance with the degree of flexibility thereof and is rotated at the connection point with the water receiving pipe 22. Therefore, the hose 18 is prevented from being bent at the connection portion with the elbow pipe 25. Here, in the case where the hose 18 swings instantly or the direction in which the hose 18 is pulled exceeds the flexible limit of the elbow pipe 25 and is different from the rotation direction of the water receiving pipe 22, the same procedure as above is taken. Can not do it.

However, since the plurality of cutout grooves 35 are provided on the distal end side of the extending portion 31 of the elbow pipe 25 in a staggered manner along the entire length thereof, the leading end side of the extending portion 31 is located at the distal end side of the elbow pipe 25. The degree of flexibility is greater than 25. Therefore, even in such a case, the tip end side of the extension portion 31 is appropriately bent by the force in the direction intersecting the longitudinal direction thereof, so that the hose 18 is connected to the elbow pipe 25 at the end portion of the extension portion 31. It is prevented from being bent and bent along with the tip side.

Therefore, as described above, it is possible to prevent bending and crushing at the connecting portion between the water receiving pipe 22 and the hose 18 without providing a separate member such as a coil spring. As a result, by eliminating the separate member, the manufacturing cost can be reduced, and a cheaper hose reel can be provided.

In this embodiment, the case where a plurality of cutout grooves 35 are provided alternately along the longitudinal direction on the entire circumference of the extension 31 of the elbow pipe 25 on the tip side is shown. Not limited to this, the notch groove 35 may be a notch hole penetrating into the hollow inside of the elbow pipe 25. Similarly, the case where the elbow pipe 25 is bellows-shaped and has a certain degree of flexibility is shown, but the elbow pipe 25 is not limited to this, and the elbow pipe 25 may have no flexibility. Also, it is possible to obtain the same effect as the above.

[0018]

[Effect of the device]

 As described above, according to the present invention, a plurality of cutouts are provided alternately on the distal end side of the extension portion of the connection pipe where the base end portion of the hose is externally inserted, and the distal end side of the extension portion is provided. Since it is bent by the force in the direction intersecting the longitudinal direction, when it is wound around the reel drum or extended from the reel drum, the hose is connected to the hose by the bending deformation at the tip of the extension part. It is possible to avoid crushing and bending at the connection part with. Therefore, the crushing and bending can be prevented without using a separate member, and as a result, a more inexpensive hose reel can be provided.
