Description

  The present invention relates to a sheet hoisting device for winding up a sheet material stretched along a frame material forming a vinyl house.

  Agricultural vinyl houses are constructed by assembling a frame material made of aluminum or steel pipe material, and stretching a sheet material made of a synthetic resin film along the frame material. Conventionally, in such a vinyl house, in order to properly adjust the temperature and humidity in the house according to the crops and other plants to be grown, a sheet material stretched on the side of the vinyl house is used with a winder. There has been one in which ventilation openings are formed by winding so that ventilation can be performed (see, for example, Patent Document 1).

  In addition, for example, in a multi-building type vinyl house, there is one in which a house ventilation device is provided in a valley formed between the roof portions of the house, and even in the case of this house ventilation device, a winder is also used. In many cases, the winder winds the sheet material covering the valleys to form a ventilation opening for ventilation.

  The upper edge of the sheet material to be opened and closed is fixed to the pipe near the ventilation opening using a fixture (not shown), and the lower edge of the sheet material for opening and closing is the longitudinal direction of the vinyl house A fixing tool (not shown) is fixed to the winding pipe arranged in One end side of the winding pipe is extended from the front (wife surface) of the vinyl house by an appropriate length, and a winder for winding the opening and closing sheet material is connected to one end of the winding pipe.

FIG. 22 shows an example in which winders are arranged on the front surface and both side surfaces in the longitudinal direction of the vinyl house. In the figure, 100 is a vinyl house, 200 is a wife face (front face) pipe connecting the lower ends of sheet materials in front of the vinyl house, 300 is a wife face winder, 310 is its operating rod, and 400 is a vinyl house. A side pipe connecting the lower end portions of the side sheet material, 500 is a wife surface winder, and 510 is an operating rod.
JP 2006-321655 A

  For example, in the case of the winder described in Patent Document 1, although it is configured to be able to rotate and operate with the operating rod tilted even if there is an obstacle directly below it, the configuration is complicated and expensive. It has become a factor.

  In addition, as shown in FIG. 22, when winders 300 and 500 are respectively disposed on the end face (front face) and the side surface in the longitudinal direction of the vinyl house, the end face pipe to which the end face winder 300 is attached. 200 and the side pipe 400 to which the side winder 500 is attached crosses up and down in the axial direction. Therefore, in order to wind up the sheet material connected and fixed to the lower face pipe 200 by the front winder 300, first, the side pipe 400 positioned at the upper side is operated by the side winder 500. The two winders 300, 500 had to be operated even when the ventilation opening 600 was formed only on the wife surface. Such a tendency often occurs because the position where the ventilation opening 600 is provided changes depending on the wind direction or the like.

  Therefore, it is desired from the market to provide a sheet winding apparatus that is cheaper and has better operability, and the present invention provides a sheet winding apparatus that can solve the above-described problems. It is an object.

  That is, the connection part 6 is comprised from the 1st, 2nd cup body 61,62 and the 1st, 2nd connection metal fittings 63,64 attached to each cup body 61 (62), This connection part There is a feature in the configuration of 6. The second cup body 62 connected to the handle 7 is called an input cup because the rotational force is inputted from the handle 7 side, and the rotational force from the handle 7 side is applied to the end face pipe 2 or the side pipe 3. The 1st cup body 61 which transmits can also be called an output cup.

  As shown in FIGS. 2 and 9, the handle 7 includes a handle body 71 formed in a crank shape by providing a grip portion 71a at one end, an adapter portion 72 connecting the other end of the handle body 71, It is comprised from the pipe-shaped extension rotation member 73 connected with the adapter part 72. As shown in FIG. Therefore, in the present embodiment, the start end of the handle 7 connected to the second cup body 62 is the start end of the extension rotation member 73. The configuration of the handle 7 will be described in detail later.

  First, the connection part 6 comprised from the 1st, 2nd cup body 61,62 and the 1st, 2nd connection metal fittings 63,64 attached to each cup body 61 (62) is demonstrated.

  As shown in FIG. 6, the first cup body 61 of the connecting portion 6 is formed with an opening 61 a for inserting the end face pipe 2 or the side pipe 3, and the handle 7 is attached to the second cup body 62. An opening 62a for insertion is formed in a cylindrical shape with a predetermined depth. As shown in FIGS. 3 to 8, in the present embodiment, the first and second cup bodies 61 and 62 are formed in the same cup shape, including the depths of the openings 61a and 62a. is doing.

  Since the first and second cup bodies 61 and 62 have substantially the same shape as described above, the first cup body 61 or the second cup body will be appropriately described below as an explanation of the specific portion thereof. One of 62 may be described as an example.

  As shown in FIGS. 4 to 6, the first cup body 61 (second cup body 62) is formed with thick portions 61 b and 61 b (62 b and 62 b) at predetermined intervals on the peripheral surface thereof. The screw seat surface 61c (62c) is formed across the thick portions 61b (62b), and the screw seat surface 61c (62c) is penetrated through the portion located in the thick portion 61b (62b). A hole 61d (62d) is formed.

  The through hole 61d (62d) penetrates from the outer peripheral surface of the first cup body 61 (second cup body 62) to the inner peripheral surface of the opening 61a (62a), and the through hole 61d (62d). It is extended by screwing a screw material (not shown) for pressing and fixing the end face pipe 2 or the side pipe 3 (extension turning member 73 of the handle 7) inserted into the opening 61a (62a). The rotating member 73 (the end face pipe 2 or the side pipe 3) is configured not to be detached and removed. The screw material is screwed into the through hole 61d (62d) so that the head portion is flush with the screw seat surface 61c (62c) and does not protrude from the peripheral surface of the cup body (61, 62). Therefore, there is no possibility that the sheet material 1 is abutted and broken.

  The base portions 62e of the first cup body 61 and the second cup body 62 are also formed thick. The second cup body 62 having the same shape as the first cup body 61 will be described as an example. As shown in FIG. 6, the thickness is increased from the bottom surface of the opening 62a to the end surface of the second cup body 62. A second connecting fitting 64 in which a bar is formed in a U shape is protruded from the base portion 62e which is a thick portion.

  That is, the 1st cup body 61, the 1st connection metal fitting 63 attached to the base parts 61e and 62e of the 2nd cup body 62, and the 2nd connection metal fitting 64 are two straight straight parts 630, and this straight line. Since the curved portions 631 and 631 are connected to each other and the curved portions 631 and 630 are connected to each other, the curved portions 631 and 630 are engaged with each other. The two connection fittings 64 are connected in a crossed state.

  In addition, the straight grooves 630 and 630 are formed with engaging grooves 632 and 632 each having a notch for engaging a pin body 61h described later, while the base portion 61e of the first cup body 61 (second cup body 62). On the end face of (62e), through holes 61f and 61f corresponding to the two straight portions 630 and 630 of the first connecting fitting 63 (second connecting fitting 64) are formed, and as shown in FIG. A fixing hole 61g that crosses the depth direction of the insertion holes 61f and 61f is provided.

  With this configuration, the left and right straight portions 630 of the second coupling fitting 64 are inserted into the insertion holes 61f, and the pin bodies 61h are inserted from the fixing holes 61g so as to engage with the two engagement grooves 632 and 632. If it does, the 2nd connection metal fitting 64 can be firmly fixed. Moreover, if the pin body 61h is extracted, the 1st connection metal fitting 63 (2nd connection metal fitting 64) can also be easily extracted from the insertion holes 61f and 61f. Therefore, when the first connection fitting 63 and the second connection fitting 64 are damaged, maintenance including easy replacement is easy.

  In FIG. 6, 61i and 62i are anti-rotation ribs formed on the bottom surfaces of the openings 61a and 62a of the first and second cup bodies 61 and 62 so as to extend from the circumferential surface toward the center. By fitting the ribs 61i, 62i into engagement grooves (not shown) formed at the ends of the end face pipe 2 or the side face pipe 3 or the handle 7, the end face pipe 2, the side face pipe 3, or the handle 7 and the first, Transmission of rotation between the second cup bodies 61 and 62 is ensured.

  Next, the handle 7 will be described with reference to FIGS.

  As described above, the handle 7 includes the handle body 71 formed in a crank shape with the grip portion 71 a provided at one end, the adapter portion 72 that connects the other end of the handle body 71, and the pipe connected to the adapter portion 72. It is comprised from the extending extension member 73 of a shape.

  The adapter portion 72 has a first opening 72a through which the other end portion of the extended rotation member 73 that connects one end to the second cup body 62 described above is inserted, on the back portion of the large diameter portion 72b formed on the front surface portion. A small-diameter portion 72d is formed integrally with a boss portion 72c connecting the handle main body 71 projecting from the back surface.

  The large-diameter portion 72b is formed with a pipe fixing through-hole 72e that penetrates the first opening 72a. A fixing screw 72f is screwed into the pipe fixing through-hole 72e, and extended by the fixing screw 72f. The moving member 73 is pressed and connected from the side. The head of the fixing screw f is screwed into the pipe fixing through hole 72e so as to be flush with the peripheral surface of the large diameter portion 72b. Therefore, since a sharp member does not protrude to the outermost side as the adapter part 72, safety is not impaired.

  On the other hand, the boss 72c is formed with a second opening 72g into which the tip of the handle body 71 is fitted, and for fixing the tip of the handle body 71 inserted into the second opening 72g. A through hole (not shown) is provided. And it is set as the structure which connects and fixes the handle | steering-wheel main body 71 reliably by inserting the fixing bolt 72h in this through-hole, and fixing with the nut 72i.

  With this configuration, when the handle portion 7 is rotated while holding the grip portion 71a, the rotation is transmitted to the second cup body 62, and the rotation of the second cup body 62 is engaged in a cross shape between the curved portions 631. The end face pipe 2 or the side surface that is transmitted to the first cup body 61 via the connecting portion 6 composed of the first and second connecting fittings 63 and 64 and connected to the first cup body 61. The pipe 3 rotates around the pipe axis, and the sheet material 1 can be wound up while being wound around the end face pipe 2 or the side pipe 3.

  In the above configuration, the sheet hoisting device 4 according to the present embodiment is characterized by the face pipe 2 or the side pipe 3 to be rolled up as shown in FIGS. 4 to 6 (see particularly FIG. 5). The second connection fitting provided on the second cup body 62 for connecting the handle 7 for hoisting the projection length H1 of the first connection fitting 63 provided on the first cup body 61 connecting the two. It is in the point made longer than 64 protrusion length H2.

  With such a configuration, it is possible to smoothly wind and unwind the end face pipe 2 or the side pipe 3 by rotating the handle 7, and to easily lock the winding and unwinding at a desired position. Become.

  Here, with reference to FIG. 5 and FIG. 6, dimensional characteristic points of the first connection fitting 63 and the second connection fitting 64 in the present embodiment will be described.

  The shaft diameter D of the first connecting fitting 63 and the second connecting fitting 64 may be determined based on strength calculation, but in this embodiment, D = 6 mm (FIG. 6).

  Further, the protruding length H1 of the first connecting fitting 63 is 32 mm, the protruding length H2 of the second connecting fitting 64 is 13 mm, and the inner dimension width W of both the connecting fittings 63 and 64 is 8 mm.

Furthermore, the inner dimension height L1 of the first coupling fitting 63 is 25 mm, and the inner dimension height L2 of the second coupling fitting 64 is 7 mm. The inner dimension width W, and particularly the inner dimension heights L1 and L2, are important for ensuring the operability and safety of the sheet hoisting device 4. In the present embodiment, regarding the relationship between the inner height L1 and L2 of 64 and the shaft diameter D of both the connecting fittings 63 and 64
D <L2 ≦ 2D <L1
The condition is satisfied.

  That is, in configuring the connection portion 6, the following was found regarding the relationship between the inner dimension height L <b> 1 of the first coupling fitting 63 and the inner dimension height L <b> 2 of the second coupling fitting 64.

Like this embodiment,
(1) When D <L2 ≦ 2D <L1, for example, when the end face pipe 2 or the side pipe 3 is wound or unwound, an attempt is made to hold it at a desired height position as shown in FIG. Thus, the handle 7 side connected to the second cup body 62 need only be suspended vertically downward. That is, in this state, as shown in the drawing, the second connecting fitting 64 having a short protruding length H2 (inner dimension height L2) attached to the second cup body 62 on the handle 7 side has a protruding length H1. It will be in the state hung by the base end part side of the linear part 630 of the 1st connection metal fitting 63 with long (inner dimension height L1). In this case, even if the end face pipe 2 or the side pipe 3 tries to descend downward due to its own weight, the straight portion 630 of the first connection fitting 63 is locked to the second connection fitting 64 or the second cup body 62. Become locked. When the weight on the handle 7 side is remarkably light, there is a possibility that the handle 7 may be lowered even if the handle 7 is flipped up and rotated. However, in the present embodiment, the handle 7 including the extended rotation member 73 is prevented so as not to occur. The weight is set. In FIG. 10, reference numeral 9 denotes a pillar material which is one of the frame materials of the vinyl house A.

(2) In the case of D <L1 = L2 ≦ 2D,
That is, when the inner dimension height of the 1st connection metal fitting 63 and the 2nd connection metal fitting 64 is equal, and there is not much difference with the shaft diameter D, specifically, the 1st cup body 61 is also 2nd in the 2nd. This is a case where the connecting metal fitting 64 is attached.

  As for the engagement between the first connecting fitting 63 and the second connecting fitting 64, the curved portions 631 are engaged with each other. Therefore, under this condition, even if the handle 7 side is hung vertically downward, the first connecting bracket 63 does not have the length of the straight portion 630 that is necessary. It hangs down at the position of the curved portion 631 of the connection fitting 63. Therefore, the first connection fitting 63 is not locked to the second connection fitting 64 or the second cup body 62, and the handle 7 side is rotated around the axis at the position of the curved portions 631. The end face pipe 2 or the side face pipe 3 falls downward due to its own weight.

(3) In the case of 2D <L1 = L2,
In this case, even when the locked state is reached, the end face pipe 2 or the side pipe 3 cannot be smoothly wound up or rewound by the rotation operation of the handle 7. That is, since both the connecting fittings 63 and 64 have the straight portions 630 having a sufficient length, the straight portions 630 may be entangled with each other. In this state, when the handle 7 is rotated, the end face pipe 2 or the side face pipe 3 undulates. Thus, an abnormal load is applied to the user side and the operability is significantly impaired.

(4) In the case of D <L1 ≦ 2D <L2,
Also in this case, as described in the case of the condition (2), since the first connecting fitting 63 does not have the length of the straight portion 630 that is necessary, the second connecting fitting 64 has the first connection fitting. It hangs down at the position of the curved portion 631 of the metal fitting 63. Therefore, the first connection fitting 63 is not locked with respect to the second connection fitting 64 or the second cup body 62. In addition, when the end face pipe 2 or the side pipe 3 is wound or unwound, the handle 7 may be operated by pulling, but if the handle 7 is loosened, the straight portion 630 of the second connection fitting 64 becomes the first portion. The state is easily engaged with the curved portion 631 of the connection fitting 63, and the operability is impaired as in the case of the condition (3).

  Thus, the end face pipe 2 or the side pipe 3 that is wound up is longer than the protruding length H2 (inner dimension height L2) of the second connecting fitting 64 provided on the second cup body 62 that connects the handle 7. Since the projection length H1 (inner dimension height L1) of the first coupling fitting 63 provided on the first cup body 61 to be coupled is increased, the rotational force due to the operation of the handle 7 can smoothly cause the face pipe 2 or the side pipe. As shown in FIG. 1, ventilation openings 12 and 13 can be easily formed in the house end face 10 and the house side face 11 of the vinyl house A.

  Further, when the user wants to stop at a predetermined winding position, the user moves the connecting portion 6 so that the axis of the extension rotation member 73 of the handle 7 and the axis of the end face pipe 2 or the side pipe 3 are substantially orthogonal to each other. If it is made to bend through, the end face pipe 2 or the side face pipe 3 is locked at that position. The substantially orthogonal state at this time may be any direction, either horizontal or vertical (see, for example, FIG. 10), but depending on the length of the extension rotation member 73 of the handle 7 in the vertical direction. May interfere with the ground, and may be bent to the vinyl house A side to hold the handle 7 with a predetermined fixture or the like.

  FIG. 11 shows the operable region α and the pipe lockable region β of the handle 7. As shown in the figure, according to the present embodiment, a range of approximately 90 degrees around the axis of the end face pipe 2 or the side pipe 3 is the operable region α, and smooth handle operation can be performed within this region α. It is possible, and a range of approximately 45 degrees outside thereof is a pipe lock region β. Within this region β, it is possible to easily lock the vertical movement of the end face pipe 2 or the side pipe 3.

  As described above, according to the sheet hoisting device 4 according to this embodiment, the operability is remarkably improved while it can be manufactured at a low cost with a very simple configuration. In addition, since the first cup body 61 and the second cup body 62 have the same shape, they can be efficiently manufactured with the same mold, so that the cost can be further reduced.

  The first cup body 61 and the second cup body 62 are functionally different as an output cup and an input cup, but are not structurally different. Therefore, it is difficult to distinguish between the two in terms of appearance. When determining which cup body 61 (62) should be attached to the end face pipe 2, the side pipe 3, or the handle 7, the first connection fitting 63 attached to each cup body 61 (62) This can also be determined by the difference in the projecting lengths H1 and H2 from the two connection fittings 64, but in order to prevent misidentification more reliably, in the present embodiment, the first cup body 61 and the second cup body 62 are used. And are color-coded. Here, the first cup body 61 is green, and the second cup body 62 is red. Any color can be used as long as it can be distinguished.

  In the sheet hoisting device 4 according to the present embodiment, as shown in FIG. 9, a boss portion 72 c for connecting the handle main body 71 is formed on the back portion of the large diameter portion 72 b of the adapter portion 72 in the handle 7. However, here, the outer shape of the boss portion 72c has a shape corresponding to the standard of the head of the hexagon bolt and the hexagon nut. Therefore, instead of the handle body 71, as shown in FIG. 12, an electric or pneumatic rotary tool 8 provided with a predetermined socket 81 can be used.

  As described above, by allowing the socket 81 of the rotary tool 8 to be mounted on the outer shape of the boss portion 72c, the physical burden on the hoisting operation of the sheet material 1 can be greatly reduced. In addition, when using the said rotary tool 8, it is especially suitable for winding up and unwinding the sheet | seat material 1 in the opening part for ventilation formed in the trough part of a continuous building type vinyl house. As the rotary tool 8, it is desirable to use a rechargeable tool.

  By the way, in the vinyl house A in this embodiment, the side pipes 3 and 3 are connected with the pipe joint 5 to have a desired length (see FIG. 1).

  As shown in FIGS. 13 to 18, the pipe joint 5 basically has the same structure as the connecting portion 6 of the sheet winding device 4 described above. The only difference from the connecting portion 6 of the sheet hoisting device 4 is that the protruding lengths of the first and second connecting fittings 63 and 64 are the same.

  Even if the plurality of side surface pipes 3 are connected in a state where they are bent at a predetermined angle with the pipe joint 5 as a boundary, for example, the whole is wound up by operating the sheet hoisting device 4. It will be. The pipe joint 5 can be applied not only to the side pipe 3 but also to the end face pipe 2.

  That is, as in the vinyl house B shown in FIG. 19, even if the house end face part 10 and the house side face part 11 are not straight but bent in plan view, a pipe joint is connected between the plurality of end face pipes 2 or side pipes 3. 5, by operating the sheet hoisting device 4, the sheet material 1 can be wound or unwound to open and close the ventilation openings 12 and 13.

  Thus, by using the pipe joint 5, it is possible to form the ventilation openings 12 and 13 even in the deformed type vinyl house B. For example, when the boundary portion of the land is not linear However, as shown in FIG. 20, by constructing a deformation type vinyl house B in the vicinity of the boundary, the number of vinyl houses can be secured, and the land can be used effectively.

  By using the pipe joint 5, not only the shape of the illustrated vinyl house B but also various deformed types of vinyl houses can be flexibly supported. In addition, the ventilation openings 12 and 13 can be easily formed.

  For example, as shown in FIG. 21, a vinyl house C constructed on a land with undulations has a shape in which the house C itself also undulates. Even in such a case, if the side pipes 3 are connected to each other by using the pipe joint 5 of the present embodiment, as shown in the drawing, the above-described sheet winding is provided at one end of the side pipe 3 located on the house end face 10 side. If the device 4 or a conventional hoisting device is mounted, even the plurality of side pipes 3 connected in an up-and-down state can be wound up or unwound simultaneously by the operation.

  Moreover, as a use of the pipe joint 5, it is possible not only to simply connect the pipes but also to interpose the pipe joint 5 between, for example, a conventional sheet material winding device and a handle connected thereto. The pipe joint 5 allows the handle shaft to be bent with respect to the input shaft of the sheet material winding device and the shaft of the hoisting pipe, so that when the sheet material winding device is installed inside the house, Thus, even in a place where it has conventionally been difficult to rotate the handle, the sheet material can be easily wound up and rewound.

  The present invention has been described based on the preferred embodiments. However, the present invention is not limited to the specific embodiments, and within the scope of the present invention described in the claims, Various modifications and changes are possible.

  In the present embodiment, the use of the sheet hoisting device 4 is for forming the ventilation openings 12 and 13. However, the present invention is not limited to this, as long as the sheet material 1 is wound up and rewound. All included. Also, the sheet material 1 may be, for example, either for a house lining or a house lining, or may be an opening / closing of a house lining curtain, a light shielding sheet, or an insect repellent sheet.

  In the present embodiment, the sheet hoisting device 4 is used to form the ventilation openings 12 and 13 on the front surface and the side surface of the vinyl house. It is also suitably used for winding a sheet material for opening and closing that opens and closes a ventilation opening provided in a trough at the lower part of the roof in a vinyl house. Furthermore, the present invention can also be applied to winding a sheet material that opens and closes a ventilation opening provided in a roof portion of a vinyl house.
