Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention relates to a hose winder that winds a hose onto a reel and stores it.

[0002]

[Prior art]

 As a winder of this type, the one disclosed in Japanese Utility Model Publication No. 7-18693 is conventionally known. In this conventional winder, a groove that travels in the axial direction is formed in the bearing hole of the bracket, and a convex portion that fits in the groove is formed around the handle shaft of the handle. Then, an elastic piece is made to project at the tip of the handle shaft, and a projection is formed at the tip of this elastic piece so as to be caught by the end portion of the above-mentioned convex portion. Therefore, if the handle shaft is inserted into the bearing hole so that the groove and the protrusion are aligned, the bracket and the handle can be slidably connected in the axial direction and can be integrally rotated, that is, a so-called spline connection. become. Then, when the two are fitted tightly together, the protrusion of the elastic piece gets over the end portion of the protrusion and is caught by it. If the projection is caught on the convex portion in this way, both will not come off in the axial direction.

[0003]

[Problems to be solved by the device]

 In the conventional winder as described above, the handle shaft is prevented from coming out of the bearing hole only by hooking the protrusion formed on the elastic piece on the end portion of the convex portion. However, if the handle shaft cannot be pulled out, the handle will be an obstacle when the hose winder is stored in a box. In other words, the handle is required to have the antinomy function that it does not come off during actual use and is easy to come out during storage, but conventional winders cannot meet such a requirement. Further, in the above-described conventional winder, when the handle is removed, if the elastic piece comes into contact with another object, it is easily broken and becomes unusable as a handle. An object of the present invention is to provide a hose winder which is easy to remove when the handle is to be removed, but rarely during use, and which is durable.

[0004]

[Means for Solving the Problems]

 This invention presupposes a hose winder in which a reel is rotatably supported by a frame and a handle is provided at one end of the reel. Based on the above-mentioned winder, this invention fixes a bracket to one end of the reel, rotatably supports this bracket on the frame, and installs a handle mounting hole in the center of the bracket. The connecting shaft portion of the handle is inserted into the mounting hole, and at the same time, the rotation stopping protrusions that come into contact with each other to prevent rotation are formed in the mounting hole and the connecting shaft portion. One of the rotation stop projections is formed with a projection on the front side in the insertion direction of the connecting shaft, and a groove on which the projection is fitted is formed on the side surface of the other rotation stop projection, and The retainer protrusion formed on the other rotation stopper protrusion is characterized in that it is configured to be hooked in front of the one rotation stopper protrusion when the protrusion and the groove coincide with each other.

[0005]

[Embodiment of device]

 In the embodiment shown in FIGS. 1 to 3, a reel r for winding a hose is rotatably supported by a frame f. That is, the tubular portion 1 is formed at one end of the reel r, and the shaft portion 2 formed on the frame f is rotatably fitted in the tubular portion 1. A bracket b is fixed to the other end of the reel r, and the bracket b is rotatably fitted in the bearing hole 3 of the frame f. In this way, the reel r is rotatably supported by the frame f. When the hose winder is stored in the transport case, the handle h is removed from the reel r to reduce the storage space and improve the transportation efficiency. Then, when using, the handle h is attached to the bracket b. Therefore, the handle h must be easily assembled to the bracket b and, once assembled, should have a structure that rarely comes off.

Therefore, in this embodiment, the connecting shaft portion 5 formed in the handle h is inserted into the assembly hole 4 formed in the bracket b. The structure of the bracket b and the handle h is as follows. . That is, as shown in FIG. 3, the bracket b is formed with four rotation preventing projections 6 at equal intervals in the circumferential direction of the assembly hole 4. However, the rotation stop projection 6 maintains a space between the rotation shaft projection 5 and the front end of the assembly hole 4 which is the front side in the insertion direction of the connecting shaft portion 5, and the two projections 7 and 7 are parallel to each other within the space. It is provided. The handle h is provided with the connecting shaft portion 5 at one end of its arm 8 and has a knob 9 rotatably attached to the end opposite to the arm 8. As shown in FIG. 3, a recessed surface 10 is formed on the outer side of the connecting shaft portion 5, and a portion protruding from the recessed surface 10 is used as a rotation stopper projection 11. Are provided at equal intervals in the circumferential direction.

Then, the retaining protrusions 12, 12 are formed on both sides of the tips of the two rotation stopper protrusions 11 facing each other, that is, on both sides of the front end portion in the insertion direction of the connecting shaft portion 5, and the rotation stopper protrusions are formed. A groove 13 is formed between 11 and the retaining projection 12. The reel hose connecting member 14 is provided at the end of the reel r on the side opposite to the bracket b. The connecting member 14 is a water guiding member 15 that connects to a water source such as a tap. Is in communication with. In the winder configured as described above, the connecting shaft portion 5 is inserted into the assembling hole 4 such that the slip-off preventing projections 12 and 12 are positioned between the rotation stopping protrusions 6 in the assembling hole 4. To do. When the connecting shaft portion 5 is fully inserted, the retaining projections 12 and 12 maintain the dimensional relationship in which they are opposed to the protrusions 7. After inserting the connecting shaft portion 5 into the mounting hole 4 as described above, both of them are relatively rotated. In this way, one of the retaining protrusions 12 rides over the protrusion 7 and is caught by the tip of the rotation preventing protrusion 6 in the assembly hole 4.

In this state, the protrusion 7 fits in the groove 13 and the side surfaces of the rotation stopper protrusions 6 and 11 are kept in contact with each other. Therefore, the relative rotation between the bracket b and the handle h is prevented by the contact between the rotation stopper projections 6 and 11, and the slip-off prevention projection 12 is caught on the tip of the rotation stop projection 6 to prevent both rotation. Is prevented from coming off. Further, in the above-mentioned state, since the rotation stopping projections 6 and 11 are in contact with each other only on one side surface thereof, when the handle h is rotated in the reverse direction, the rotation stopping projections 6 and 11 are separated from each other. Rotate relative to the direction. When the two relatively rotate in the opposite directions in this way, the retaining protrusion 12 which has been in the protrusions 7 and 7 is removed from the protrusion 7, and the protrusion 12 is positioned on the opposite side to the protrusion 12. The retaining protrusion 12 that has been used is fitted between the protrusions 7 and 7 located forward of the rotation direction. Further, when the handle h is pulled out, before the retaining protrusion 12 is fitted between the protrusions 7 and 7 located forward in the rotation direction, that is, the retaining protrusions 12 are rotated to prevent the retaining protrusions 6 and 6. The handle h can be easily removed by pulling out the connecting shaft portion 5 from the assembling hole 4 when it is located in between. Reference numeral 16 in the drawing is a rib provided in the connecting shaft portion 5.

[0009]

[Effect of device]

 In the hose winder of the present invention, when the connecting shaft portion of the handle is inserted into the mounting hole of the bracket and they are rotated relative to each other, the retaining protrusion passes over the protrusion and the rotation stopper protrusion in the mounting hole. It will be caught at the tip of the part, so it will not come off while the handle is rotating. Further, in the above-mentioned state, the protrusion is fitted in the groove and the side faces of the rotation stopping protrusion 6 contact each other, so that the relative rotation of the bracket and the handle is prevented. In addition, if the handle is rotated in the reverse direction, the retaining protrusion will go over the protrusion and come off, so the handle can be easily removed. Furthermore, in this winder, since the member for preventing the handle from coming off is a protrusion or a protrusion, unlike the conventional elastic piece, problems such as damage do not occur.
