Description

  The present invention relates to a hose reel.

  An example of a hose reel is described in Japanese Patent Application Laid-Open No. 2003-201066.

  FIG. 5 is a plan view when the hose reel described in the publication is viewed from above, and FIG. 6 is a side view when viewed from the side.

  A hose reel 50 shown in FIGS. 5 and 6 includes a hose reel main body 1, a circular drum 7 rotatably mounted inside the hose reel main body 1, and a winding fluctuation device 11 including two sets of gear pairs. It is equipped with.

  A hose 6 is wound around the circular drum 7.

  The hose reel body 1 is provided with a first hole 9 for inserting an electric screwdriver and a second hole 10 for inserting a handwheel handle.

  The winding variation device 11 includes four gears, that is, a first gear 16B, a second gear 15B, a third gear 16A, and a fourth gear 15A. The first gear 16B and the second gear 15B mesh with each other, and the third gear 16A and the fourth gear 15A mesh with each other. The first gear 16B has a larger diameter than the second gear 15B, and the third gear 16A has a larger diameter than the fourth gear 15A.

  Either the automatic winding of the hose 6 by the electric screwdriver or the manual winding of the hose 6 by the handwheel for handling can be selected via the winding fluctuation device 11.

  When an electric screwdriver is inserted into the first hole 9, the electric screwdriver is connected to the rotary shaft 8 of the circular drum 7 via the first gear 16B and the second gear 15B. When the electric screwdriver is operated, the rotational force of the electric screwdriver is transmitted to the rotary shaft 8 of the circular drum 7 via the first gear 16B and the second gear 15B, thereby rotating the circular drum 7 (that is, the hose 6 is wound up). ).

  When the handwheel handle is inserted into the second hole 10, the handwheel handle is connected to the rotary shaft 8 of the circular drum 7 via the third gear 16A and the fourth gear 15A. When the handwheel handle is rotated, the rotational force of the handwheel handle is transmitted to the rotary shaft 8 of the circular drum 7 via the third gear 16A and the fourth gear 15A, and the circular drum 7 is rotated (that is, the hose 6 is rotated). Rolled up).

  As described above, according to the hose reel 50 shown in FIGS. 5 and 6, the hose 6 can be wound around the circular drum 7 by either the electric screwdriver or the handle for turning by hand. Since the rotational force of the handwheel is transmitted to the rotary shaft 8 of the circular drum 7 through two gears (first gear 16B and second gear 15B or third gear 16A and fourth gear 15A), respectively, an electric driver Alternatively, the rotation direction of the handwheel handle and the rotation direction of the circular drum 7 are opposite to each other.

  That is, since the direction in which the electric screwdriver or the handwheel is rotated and the direction in which the hose 6 is wound are opposite to each other, it cannot be said that the workability is good for the user.

  The present invention has been made in view of the problems in the conventional hose reel, and the rotation direction of a handle (or an electric drive means such as an electric screwdriver) for rotating the drum and the rotation direction of the drum (that is, An object of the present invention is to provide a hose reel that matches the direction in which the hose is wound up.

  To achieve the above object, the present invention provides a hose reel body, a drum rotatably attached to the hose reel body inside the hose reel body, and a hose reel body rotatably attached to the outside. A hose reel comprising: a handle that rotates the drum by rotating; and a gear mechanism that transmits the rotation of the handle to the drum, wherein the gear mechanism is engaged with an odd number of 3 or more. A hose reel that is made of a gear is provided.

  For example, the diameter of the gear directly connected to the handle is preferably larger than the diameter of the gear directly connected to the drum.

  For example, the diameter of the gear directly connected to the handle is preferably smaller than the diameter of the gear directly connected to the drum.

  It is preferable that the gear is detachably attached to the hose reel body, the drum, and the handle.

  Furthermore, the present invention provides a hose reel main body, a drum attached to the hose reel main body so as to be rotatable inside the hose reel main body, and is rotatably attached to the outside of the hose reel main body. There is provided a hose reel comprising a handle for rotating the drum, and a chain belt mechanism for transmitting the rotation of the handle to the drum so that the rotation direction of the handle is the same as the rotation direction of the drum.

  In the hose reel according to the present invention, the handle and the drum are connected via a gear mechanism including an odd number of three or more gears. For this reason, the rotation direction of the handle and the rotation direction of the drum always coincide. Specifically, when the handle is rotated in the counterclockwise direction, the drum also rotates in the counterclockwise direction, and when the handle is rotated in the clockwise direction, the drum also rotates in the clockwise direction. As described above, according to the hose reel according to the present invention, the rotation direction of the handle and the rotation direction of the drum (that is, the direction in which the hose is wound) coincide with each other, so that the workability is greatly improved for the user.

(First embodiment)
FIG. 1 is a plan view of a hose reel 100 according to the first embodiment of the present invention as viewed from above.

  The hose reel 100 according to this embodiment includes a box-shaped hose reel body 110 having a hollow inside, a drum 120 attached to the hose reel body 110 so as to be rotatable inside the hose reel body 110, and a hose reel body 110. The handle 130 is detachably and rotatably attached to the outside, and a gear mechanism 140 that transmits the rotation of the handle 130 to the drum 120.

  A hose 125 is wound around the drum 120 (therefore, the drum 120 is not visible in FIG. 1).

  The handle 130 is connected to the rotating shaft 121 of the drum 120 through the gear mechanism 140. By rotating the handle 130, the rotational force of the handle 130 is transmitted to the rotating shaft 121 through the gear mechanism 140, and the rotating shaft is rotated. As a result, the drum 120 can be rotated.

  The gear mechanism 140 includes three gears, that is, a first gear 141, a second gear 142, and a third gear 143. Both are rotatably attached to the hose reel body 110.

  The first gear 141 is directly connected to the shaft of the handle 130 and rotates in synchronization with the handle 130.

  The third gear 143 is directly connected to the rotation shaft 121 of the drum 120 and rotates in synchronization with the drum 120.

  The second gear 142 is disposed between the first gear 141 and the third gear 143 and meshes with both the first gear 141 and the third gear 143.

  FIG. 2 is a schematic diagram showing the size of the first gear 141, the second gear 142, and the third gear 143 and the positional relationship between them.

  As shown in FIG. 2, the diameter of the first gear 141 directly connected to the handle 130 is set larger than the diameter of the third gear 143 directly connected to the drum 120.

  The hose reel 100 according to the present embodiment having the above structure operates as follows.

  When the hose reel 100 is used, the hose 125 is pulled out from the drum 120 for use. When pulling out the hose 125 from the drum 120, the drum 120 rotates in a clockwise direction.

  When the hose 125 is rewound onto the drum 120 after the use of the hose reel 100, the handle 130 is rotated in the counterclockwise direction.

  As shown in FIG. 2, when the handle 130 is rotated in the counterclockwise direction, the first gear 141 directly connected to the handle 130 is also rotated in the counterclockwise direction. Accordingly, the second gear 142 meshed with the first gear 141 rotates in the clockwise direction. As the second gear 142 rotates in the clockwise direction, the third gear 143 rotates in the counterclockwise direction.

  Since the third gear 143 is directly connected to the rotating shaft 121 of the drum 120, the drum 120 also rotates counterclockwise as the third gear 143 rotates counterclockwise, and the hose 125 rotates the drum 120. Rolled up.

  Thus, in the hose reel 100 according to the present embodiment, when the handle 130 is rotated in the counterclockwise direction when the hose 125 is wound, the drum 120 is also rotated in the counterclockwise direction. That is, the drum 120 rotates in the same direction as the handle 130.

  As described above, according to the hose reel 100 according to the present embodiment, the rotation direction of the handle 130 and the rotation direction of the drum 120 (that is, the direction in which the hose 125 is wound) coincide with each other. Workability can be greatly improved.

  The hose reel 100 according to the present embodiment is not limited to the above structure, and various modifications can be made.

  For example, in the hose reel 100 according to this embodiment, the gear mechanism 140 includes three gears 141, 142, and 143, but the number of gears that configure the gear mechanism 140 is not limited to three. It is possible to select any odd number of 3 or more as required. By configuring the gear mechanism 140 from an odd number of three or more gears, the rotation direction of the handle 130 and the rotation direction of the drum 120 can be matched.

  Further, in the hose reel 100 according to the present embodiment, as shown in FIG. 2, the diameter of the first gear 141 directly connected to the handle 130 is the same as that of the third gear 143 directly connected to the rotating shaft 121 of the drum 120. It is set larger than the diameter.

  For this reason, when the handle 130 and thus the first gear 141 are rotated once, the third gear 143 and thus the drum 120 is rotated at a ratio of 1 rotation or more (exactly, it depends on the gear ratio between the first gear 141 and the third gear 143). Rotate at a ratio). Therefore, it is possible to rotate the third gear 143 and thus the drum 120 at a relatively large speed.

  FIG. 3 is a schematic diagram showing the size of the first gear 141, the second gear 142, and the third gear 143 and the positional relationship between them in a modified example.

  As shown in FIG. 3, the diameter of the first gear 141 directly connected to the handle 130 can be set smaller than the diameter of the third gear 143 directly connected to the rotating shaft 121 of the drum 120.

  In this case, when the handle 130 and the first gear 141 are rotated once, the third gear 143 and the drum 120 rotate at a ratio of less than one rotation. For this reason, the rotation speed of the third gear 143 and thus the drum 120 is reduced, but the drum 120 can be rotated with a smaller load.

  Further, the first gear 141, the second gear 142, and the third gear 143 may be fixedly attached to the hose reel main body 110, or may be detachably attached to the hose reel main body 110.

  By attaching the first gear 141, the second gear 142, and the third gear 143 to the hose reel body 110 so as to be detachable, any one or more of the first gear 141, the second gear 142, and the third gear 143 can be connected. Since the gear can be replaced with another gear, the gear ratio between the first gear 141 and the third gear 143 can be changed to a desired gear ratio.

(Second embodiment)
FIG. 4 is a partial plan view of a hose reel 200 according to the second embodiment of the present invention.

  Compared with the hose reel 100 according to the first embodiment, the hose reel 200 according to the present embodiment includes a chain belt 210 instead of the gear mechanism 140.

  That is, in the hose reel 200 according to the present embodiment, the shaft of the handle 130 and the rotating shaft 121 of the drum 120 are connected via the chain belt 210 as shown in FIG.

  For this reason, if the handle 130 rotates in the clockwise direction, the drum 120 also rotates in the clockwise direction, and if the handle 130 rotates in the counterclockwise direction, the drum 120 also rotates in the counterclockwise direction. .

  Thus, also with the hose reel 200 according to the present embodiment, the rotation direction of the handle 130 and the rotation direction of the drum 120 (that is, the direction in which the hose 125 is wound) coincide with each other. It can be greatly improved.

  It should be noted that a transmission mechanism may be provided on the chain bell 210 as necessary.
