  The operation itself of the film winder 1 is the same in the conventional example shown in FIG. 1B and in the present invention, and the input shaft 5 of the film winder 1 is rotated by the manual handle 16 or the electric drill 17 described later. When the take-up shaft 6 is rotated via a gear mechanism or the like, the greenhouse film 12 is wound on the take-up shaft 6 and wound up, and the take-up shaft 6 is raised.

  As a result, the entire film winder 1 is raised while the guide portion 3 slides upward along the guide column 2, and a part of the greenhouse covered with the film 12 is opened.

  The feature of the present invention is that the adapter 21 according to the present invention is fixedly attached to the input shaft 5 and any one of the manual handle 16 and the electric drill 17 as a rotary tool is selectively attached to and detached from the adapter 21. The film winder 1 can be rotationally driven via the adapter 21 regardless of whether the manual handle 16 or the electric drill 17 is used (FIG. 4A, ( b), see FIG.

  As shown in FIGS. 2A and 2B, the adapter 21 is fixedly attached to the input shaft 5 of the film winder 1 on the front end side in the longitudinal direction (the right side in FIG. 2A). The attachment portion 22 is formed, and the manual handle 16 and the electric drill 17 can be selectively and interchangeably connected to the base end side in the longitudinal direction (left side in FIG. 2A) so as to be detachable. A portion 23 is formed.

  The mounting portion 22 is formed as a cylinder, and a bolt insertion hole 26 through which the mounting bolt 37 is inserted in a direction orthogonal to the longitudinal direction is formed at the tip side.

  In the present embodiment, the mounting portion 22 of the adapter 21 is formed in a cylindrical shape, but the mounting portion 22 is fixedly mounted on the input shaft 5 of the film winder 1 and can be rotatably connected together. As long as it is not a cylinder, it may be a cylinder, a rectangular tube, a prism, or the like. Even in the case of these shapes of cylinders and columns, bolt insertion holes are formed.

  The coupling portion 23 of the adapter 21 includes both a manual handle coupling portion to which the manual handle 16 can be coupled and an electric drill coupling portion to which the electric drill 17 can be coupled.

  Specifically, as shown in FIGS. 2A and 2B, as an electric drill coupling portion, the coupling portion 23 of the adapter 21 includes an outer peripheral surface 27 having a hexagonal cross-sectional shape perpendicular to the axis thereof. Yes. Further, as a manual handle coupling portion, the coupling portion 23 of the adapter 21 includes a cylindrical hole 28 and a fixing pin insertion hole 31.

It is a hole for inserting a fixing pin 32 with a leaf spring for coupling in a rotatable manner.

  In other words, the coupling portion 23 of the adapter 21 of the present embodiment is formed as a hexagonal cylinder as viewed from the exterior, and has a hexagonal outer peripheral surface 27 as an electric drill coupling portion, and as a manual handle coupling portion. A cylindrical hole 28 having a circular inner peripheral surface and a fixing pin insertion hole 31 are provided.

  The coupling portion 23 of the adapter 21 is a hexagonal cylinder as viewed from the outside, that is, the outer shape of the cross section orthogonal to the axis of the adapter 21 is a hexagonal shape. This is a hexagonal socket hole 49 of the hexagonal socket 46 of the electric drill 17 described later. If the square socket fits from the outside and can be rotated together with the shape of the square socket of the electric drill 17, it is not a hexagonal shape but other square shapes such as a quadrangular shape and a pentagonal shape. May be.

  When the manual handle 16 is coupled to the adapter 21 and the film winder 1 is rotationally driven by the manual handle 16 via the adapter 21, the leaf spring as shown in FIGS. An attached fixing pin 32 is used. The fixing pin 32 itself is formed as a cylindrical axis, and is formed in a hemispherical shape as shown at the tip end face (the right end face in FIG. 3A).

  As shown in FIG. 3A, the leaf spring 35 is formed in a substantially U shape when viewed from the front, extends along the longitudinal direction of the fixing pin 32, and a base end portion 36 thereof is the fixing pin 32. Is fixed to the base end face (the left end face in FIG. 3A). The lateral width of the leaf spring 35 is substantially the same as the diameter of the fixing pin 32 as shown in FIG.

  When the adapter 21 is not used, if the fixing pin 32 with a leaf spring is attached to the adapter 21, the adapter 21 and the fixing pin 32 with a leaf spring are set and do not fall apart to prevent loss or the like. Can do.

  To attach the fixing pin 32 with leaf spring to the adapter 21, as shown in FIGS. 2C and 2D, the fixing pin 32 with leaf spring is inserted into the fixing pin insertion hole 31 of the adapter 21, The leaf spring 35 is elastically pressed against the outer peripheral surface 27 of the coupling portion 23 of the adapter 21. As a result, the fixing pin 32 with the leaf spring cannot be easily removed from the fixing pin insertion hole 31 of the adapter 21 and can be prevented from coming off.

  The adapter 21 is mounted on the input shaft 5 of the film winder 1 and is rotatably connected to the adapter 21, and either one of the manual handle 16 and the electric drill 17 is selectively and replaceably coupled to the adapter 21, The procedure for rotationally driving the film winder 1 via the adapter 21 by any one will be described in the section of action described later.

(Function)
In order to clarify the configuration and effects of the adapter 21 according to the present invention, the method of use, action, and the like will be described below.

  As described above, the feature of the present invention is that the adapter 21 is attached to the input shaft 5 of the film winder 1 so as to be rotatable together, and either one of the manual handle 16 and the electric drill 17 is connected to the adapter 21. The film winder 1 can be driven to rotate via the adapter 21 even if any of these rotary tools are used, which are selectively and interchangeably coupled.

  When the manual handle 16 is detachably coupled to the adapter 21 and the film winder 1 is rotationally driven by the manual handle 16 via the adapter 21, the electric drill 17 is detachably coupled to the adapter 21, and the electric drill 17 The case where the film winder 1 is rotationally driven through the adapter 21 and the case where the manual handle 16 and the electric drill 17 are used interchangeably will be described.

  When the film winder 1 is driven and operated by either the manual handle 16 or the electric drill 17, the adapter 21 is fixedly attached to the film winder 1, and the manual handle 16 or the Since the electric drill 17 is detachably coupled to the adapter 21 and used, first, a method of mounting the adapter 21 on the film winder 1 will be described.

  The mounting portion 22 of the adapter 21 is fitted and inserted into the cylinder of the cylindrical input shaft 5 of the film winder 1, and the mounting bolt 37 is inserted into the bolt insertion hole 11 of the input shaft 5 and the bolt insertion hole in the adapter 21. 26, and the nut 38 is screwed and tightened from the other end side. As a result, the adapter 21 is fixedly attached to the input shaft 5 of the film winder 1, and both are rotatably connected.

  As described above, the case where the manual handle 16 is attached to the film winder 1 and the film winder 1 is rotationally driven through the adapter 21 attached to the film winder 1 will be described.

  The manual handle 16 used in this embodiment includes a crankshaft 40 as shown in FIG. The crankshaft 40 is provided with a gripping portion 41 on the proximal end side, and a coupling shaft 42 on the distal end side. A fixing pin insertion hole 43 is formed on the distal end side of the coupling shaft 42.

  When the manual handle 16 is attached, the coupling shaft 42 is inserted into the cylindrical hole 28 of the coupling portion 23 of the adapter 21 as shown in FIG.

  Then, the fixing pin 32 with the leaf spring is inserted so as to penetrate the fixing pin insertion hole 31 in the adapter 21 and the fixing pin insertion hole 43 of the coupling shaft 42 in the manual handle 16. This insertion is performed until the U-shaped leaf spring 35 is elastically pressure-bonded to the hexagonal outer peripheral surface 27 of the coupling portion 23 of the adapter 21.

  In this way, as shown in FIGS. 4A and 4B, the manual handle 16 can be rotatably coupled to the adapter 21 together. Then, by rotating the manual handle 16, the rotational force is transmitted to the input shaft 5 of the film winder 1 through the adapter 21, and the film winder 1 can be driven to rotate, and the film 12 is wound. It becomes possible to wind around the shaft 6.

  In addition, since the leaf spring 35 is elastically pressed against the outer peripheral surface 27 of the coupling portion 23 of the adapter 21 with the manual handle 16 coupled to the adapter 21, the fixing pin 32 with the leaf spring is connected to the adapter 21. Can be prevented from being easily removed from the fixed pin insertion hole 31 and the fixed pin insertion hole 43 of the manual handle 16, and as a result, the manual handle 16 can be prevented from being removed from the adapter 21, thereby being stable and safe. Handle operation is possible.

  Next, the case where the electric drill 17 is used will be described. The “electric drill” according to the present invention includes a tool attachment member such as a chuck, and a normal electric drill, electric drill driver (electric drill and electric screw driver) to which a tool such as a drill can be attached as a tool by the tool attachment member. An electric rotary tool such as a dual-purpose tool.

  In addition, if it is an electric rotary tool which can attach tools, such as a hexagon socket for couple | bonding with the adapter 21, instead of the electric drill used for this invention, the electric screwdriver normally used for screw tightening Therefore, the “electric drill” in the present invention substantially includes the electric driver as described above.

  When the electric drill 17 is used, a hexagon socket 46 as shown in FIGS. 5A to 5C is used in this embodiment. The hexagon socket 46 includes a proximal-side mounting shaft 47 and a distal-side socket portion 48.

  The socket part 48 has a hexagon socket hole 49. The hexagon socket hole 49 is formed in a hexagonal shape so that its cross-sectional shape fits snugly into the coupling portion 23 of the adapter 21 from the outside (see FIG. 5C).

  In short, the hexagonal cross-sectional shape orthogonal to the axial direction of the hexagon socket hole 49 is similar to the hexagonal cross-sectional shape orthogonal to the axial direction of the coupling portion 23 of the adapter 21, but is slightly larger. ing. In addition, a rectangular socket having a polygonal socket hole may be used instead of the hexagon socket.

  Such a hexagon socket 46 is attached to the electric drill 17 by fastening its mounting shaft 47 to the chuck of the electric drill 17. When the electric drill 17 is turned on, the electric drill 17 and the hexagon socket 46 are rotated, the input shaft 5 is rotated via the adapter 21, the film winder 1 is rotated, and the film 12 is wound. Operation is possible.

  As described above, when changing from using the manual handle 16 shown in FIGS. 4A and 4B to using the electric drill 17 shown in FIG. 5A, the elasticity of the leaf spring 35 is reduced. Accordingly, the fixing pin 32 with the leaf spring is pulled out from the coupling shaft 42 of the adapter 21 and the manual handle 16, and the manual handle 16 is removed from the adapter 21 while the adapter 21 is attached to the input shaft 5.

  Then, as shown in FIG. 5 (a), the hexagon socket hole 49 of the hexagon socket 46 attached to the electric drill 17 is fitted from the outside into the coupling portion 23 of the adapter 21 with the fixed pin 32 with the leaf spring removed. Just go together.

  As shown in FIG. 5A, when using the manual handle 16 from the state where the electric drill 17 is used, the hexagon socket 46 is pulled out from the coupling portion 23 of the adapter 21. Then, as described above, the coupling shaft 42 of the manual handle 16 is inserted into the cylindrical hole 28 of the coupling portion 23 of the adapter 21 as shown in FIG.

  As described above, the fixed pin 32 with the leaf spring is inserted so as to pass through the fixed pin insertion hole 31 in the adapter 21 and the fixed pin insertion hole 43 in the manual handle 16, and the leaf spring 35 is connected to the coupling portion of the adapter 21. The outer peripheral surface 27 of the hexagonal shape 23 is elastically pressed to prevent it from coming off. As a result, the manual handle 16 can be rotatably coupled to the adapter 21.

  As described above, when the adapter 21 according to the present invention is mounted on the film winder 1 and used as the rotation driving means of the film winder 1, either the manual handle 16 or the electric drill 17 can be selectively used. It can be used easily.

  As mentioned above, although the form for implementing the adapter for film winders for rotating a film winder with the rotary tool which concerns on this invention was demonstrated based on the Example, this invention is in such an Example. It goes without saying that there are various embodiments within the scope of the technical matters described in the claims.
