(Points of interest)
Japan has a long and narrow land in the north and south, and its topography is complicated as inland, inland seas, islands, mountains, flat lands, basins, slopes, etc. It has a unique climate and climate conditions that vary greatly from place to place, such as the Pacific High that strengthens the power and the cold air masses that protrude from Siberia in winter. In order to maintain farming, various forms of cultivation have been developed depending on the land, but a plastic greenhouse that makes effective use of solar energy has also been created for this purpose. An example.

    This greenhouse keeps the crop at an appropriate temperature, protects the crop from the effects of wind and rain, and is advantageous for cultivating and managing the crop during the cultivation period, such as irrigation, fertilization management, pest control, etc. There are many advantages over open field cultivation, such as the ability to implement year-round cultivation, and it is a simple facility that requires less economic burden and is easy to introduce. The farmland and the natural environment that greatly changes the climate throughout the four seasons are well suited to Japan's agricultural circumstances for stable production of high quality crops. It is widely spread and used nationwide as a variety of uses and sizes, such as medium-sized ones for cultivating fruits and vegetables, and large ones for cultivating fruit trees such as cherries. It has come to see the Sheng.

    In such widely used greenhouses, especially medium- and large-sized greenhouses, in general, a large number of zinc-plated steel pipes are arranged at predetermined intervals in the building direction. It has a structure in which a house skeleton such as a round roof type, a single roof type, a double roof type, or a double gradient type is formed, and a plastic sheet such as vinyl chloride is stretched on its outer surface. Indispensable vinyl sheets are used over a single year or several years, and are subject to repeated differences in wind and rain, sunlight, and temperature, gradually degrading and reducing translucency, enough to capture sunlight In addition to inconveniences such as the loss of elasticity and the inconvenience of being easily torn by external forces such as strong winds, rain, hail, snowfall, etc. From the fact that there is also a compelling problem that be must protect the facility from snow or wind damage, etc., in each case removed from the house skeleton, if necessary, will be accompanied always work to be re-stretched again.

(Conventional technology)
However, the vinyl sheet laying work on the greenhouse skeleton must be seamless and long for the purpose, and the left and right sides of the skeleton are not so strong. Since it must be distributed to the entire building and attached to the entire building, the work is very large, and it is quite complicated and dangerous. Work load is to be forced, so as to reduce such a load as much as possible, so far, for example, as in the "house sheet tensioning device" invention disclosed in JP-A-7-289092, A sheet guide portion is movably provided along a movement guide portion disposed in the longitudinal direction of the house, and the leading end portion of the sheet is engaged with the sheet guide portion. In addition, a structure in which a sheet can be stretched while being automatically moved along the roof surface, or “a roof sheet extending method in a greenhouse and an auxiliary tool for roof sheet extending” disclosed in JP-A-8-214710. A zigzag comprising a movable auxiliary tool having a traveling part movable in the ridge direction on the roof of the house skeleton, and a sheet mounting frame substantially orthogonal to the ridge along the arch shape of the roof. A vinyl that is represented by a sheet that is folded in a shape and mounted on the sheet mounting base, and the sheet is stretched in an unfolded manner while moving the traveling part in the ridge direction. Developments and proposals have been made for various technologies for setting up a house.

(Awareness of problems)
However, such conventional sheet laying equipment and roof sheet extending auxiliary tools, etc., are relatively large in size, and require a large amount of installation work for installation and a large amount of costs associated therewith. In addition, a lot of work must be spent on the removal work after the greenhouse has been set up. In addition, the sheet tensioning operation cannot be performed with the multiple sheet tension strings stretched across the entire skeleton body beam direction, and when the sheet is repositioned, Since all the sheet tension strings have been removed once and the sheets have been tensioned, it becomes necessary to transfer the sheet tension strings again. A lot of time and labor must be spent for the work of laying the sheet tension string, and in the meantime, if strong winds, rain, snow, etc. are blown in rough weather, the sheet flutters, and the sheet tension string It was not possible to easily reduce the burden of the replacement work, for example, the transfer work would be very difficult.

(Object of invention)
Therefore, in the present invention, in view of the above situation, in order to realize an efficient, simple, and quick operation of laying a sheet on a greenhouse, even with a small number of people, the development and research have been started quickly and over a long period of time. As a result of repeating trial and error and many trial productions and experiments, the same person has already completed the invention of “sheet tensioning device in a greenhouse and its method of use” published in Japanese Patent Application Laid-Open No. 2004-121076. As a result of practical application, we succeeded in realizing a sheet tensioning tool for sheet feeding in an improved-structured greenhouse that enables smoother work. The construction of the present invention will be described in detail together with the embodiment representing the present invention.

(Structure of the invention)
As clearly understood from the embodiments representing the present invention shown in the drawings, the sheet tensioning tool of the greenhouse according to the present invention is an outer periphery of a large number of portal skeletons erected at predetermined intervals in the lateral direction. It is related to one of the equipment that is required to stretch the plastic sheet to block the outside world and make it possible to achieve the functions of windproof, rainproof, heat insulation, etc. It consists of the following composition.
That is, a tow frame that is formed in a symmetrical symmetrical sharp shape, and a follower frame that is formed in a substantially trapezoidal frame shape and whose upper base is set to a length that substantially matches the left and right width of the rear end of the tow frame. And a substantially trapezoidal shape having an upper base having a length substantially coincident with the lower base of the following frame, and at an appropriate position, a portion where appropriate edges of the greenhouse wearing sheet are bundled in a substantially sharp shape is removed. A connection frame having a connection mechanism that can be temporarily connected so that it cannot be pulled out, and is connected between the rear end of the leading frame for traction and the upper bottom side of the tracking frame and the lower base side of the tracking frame. A hinge mechanism is provided between each frame and the bottom of the frame so that they can be bent with each other, and are connected so as to have a sharp and divergent shape when expanded as a whole, and at least the top of the leading frame for traction From the vicinity, it rises at a relatively small angle with respect to the top frame for towing, The length of the follower frame is set to a length that reaches the lower base of the follower frame that is unfolded in a single plane following the tow top frame, or slightly beyond it to reach the connecting frame side. This is a sheet tensioning tool for sheet feeding in a greenhouse, which has a structure in which a diving rod for avoiding a sheet tension string, which is stretched and formed in the shape of a straight bar passing through substantially the center upper side, is projected.

    When the sheet tensioning tool for sheet feeding in the greenhouse of the present invention is shown as a more specific configuration, it is formed in a sharp shape such as a substantially triangular shape or a substantially trapezoidal shape that is bilaterally symmetric, from the tip to the vicinity of the middle A tow top frame integrally formed with a rope connecting portion in any suitable position, and a length that is formed in a substantially trapezoidal frame shape of the size of a palm, with the upper base approximately equal to the left and right width of the rear end of the tow head frame Is formed in a substantially trapezoidal shape having a tracking frame set to a length and an upper base of a length that substantially matches the lower base of the tracking frame. And a connecting frame that has a connecting mechanism that can be temporarily attached so that it cannot be removed, and between the rear end of the leading frame for traction and the bottom of the follower frame, and Provide a hinge mechanism between the bottom bottom of the tracking frame and the top bottom of the connecting frame. It is foldable and connected so as to have a sharp, divergent shape when the whole is deployed in one plane, and at least from the vicinity of the top of the top frame for towing, It rises at a relatively small angle of about 1 to 20 degrees, preferably about 15 degrees, and reaches or slightly exceeds the lower bottom side of the following frame that is developed in a single plane following the towing head frame. It is set to a length that reaches the connecting frame side, and is formed by projecting a diving rod for extending the formed straight rod passing through the substantially upper center in the width direction of the follower frame to avoid the sheet tension string It becomes a sheet stretching tool for sheet feeding in a greenhouse.

    As described above, according to the sheet tensioning tool for sheet feeding in the greenhouse according to the present invention, the conventional method for tensioning the sheet to the house requires a large amount of manpower and performs dangerous work at high places. Otherwise, it would be necessary to spend a great deal of money and labor, such as mounting a large stretcher on the roof of the house and operating the device remotely, etc. While it was a heavy burden for the farmers who operated, the portal skeletons arranged in parallel at appropriate intervals in the direction of the ridge of the greenhouse, and over the portal skeletons in the direction between the beams The sheet tensioning tool for feeding the sheet is connected to one side of the traction line hung on one end side in the ridge direction so as to pass between the sheet tensioning strings and the connection Part where sheets are bundled in the mechanism , And the other side of the tow rope hanging from the other end in the ridge direction is towed by appropriate means near the ground, so that the seat can be quickly and safely stretched. Of course, the inconveniences up to 1 can be solved at once, and the work developed by the same person can be made more efficient, so that work by a small number of people, such as one person or several people, can be made sure and safe. It will be possible to further improve the efficiency of the installation work, greatly reduce costs, and achieve an excellent effect of realizing an economical facility-type agricultural operation.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The leading frame for towing is pulled in the ridge direction from the one end side on the portal skeleton prior to the follower frame and the connecting frame following the rear end, and the ridge direction is between the portal skeleton and the seat tension string. Cross section perpendicular to the pulling direction of the tip portion, which serves to guide the bundle-like sheet temporarily attached to the attachment frame over the stretched range by passing to the other end side However, it is preferably set as small as possible, and is generally sharp from the front end to the rear end, and is preferably formed in an isosceles triangle shape having a top portion as a vertex, or a trapezoidal planar shape, a plate shape, It can be set to an outer shape such as a columnar shape or a cone shape, and it must be provided with a dive rod protruding from the right side of the upper side in use to avoid the sheet tension string Whether it is in the proper position from the side to the center or near the base of the dive. In addition, it is possible to integrally form a connecting portion for a towing line such as a ring or a hook in an appropriate position, so that the main body itself can be formed in a frame shape, and the towing line can be tied to the tip. It can also be used as a leading tow frame.

    The tow rope is incidentally necessary when using the sheet tensioning tool for sheet feeding, and is connected to the sheet tensioning tool, and the traction force can be transmitted to the sheet tensioning tool to guide the towing. It passes through between the portal skeleton and the seat tension string, is stretched over the house ridge, and a part of the seat is grounded through the seat tension tool. Can be mounted on the winder that is installed on the ground section outside the house or on the truck bed, or can be started by a person or an agricultural tractor, etc. It has a length that is long enough to allow towing, and has sufficient strength to withstand the towing work of the seat. So as not to put a heavy burden Is set to Article diameter, outside of the rope, relatively light strands of material, for example, string or wire rope, piano wire or the like are included.

    The tracking frame connects the leading end frame for towing or the leading end portion of the leading frame for towing and the front end portion of the connecting frame so as to be foldable in a predetermined direction to increase the flexibility of the sheet stretching tool and It functions to transmit the traction force applied to the leading frame or towing leading frame to the subsequent connecting frame, and basically substantially matches the rear left and right width dimensions of the towing leading frame or towing leading frame. It should be formed in a substantially trapezoidal plane shape with an upper base on the length, with the upper base on the leading edge of the towing head frame or the rear end of the towing head, and the lower base on the connecting frame. It must be connected to the upper base so as to be rotatable in a predetermined direction via a hinge mechanism, respectively, and the lower base can be formed in a bowl shape so that the protective sheet can be attached. , In the right place between the upper base and the lower base Only can be assumed that projecting from the drawn pair or three or more submerged rod to.

    The protective sheet has many connecting parts of the vinyl sheet connected to the connecting frame from the outside, pulled to the ridge direction on the portal skeleton, and when it goes under the sheet tension string, it becomes a vinyl sheet It serves to reduce and protect the applied friction and load, and is made of a low-friction material that has a sufficient area to conceal the connecting portion of the vinyl sheet and is relatively durable. In addition to the simple rectangular sheet material, the width around the center of the bottom of the tracking frame should be approximately the same as the width of the bottom of the bottom of the tracking frame. A joining frame including a joining mechanism, which can be made of a sheet having a different shape that is cut and formed to follow the right and left contour shapes of the frame and the joining frame so that wrinkles are less likely to occur when attached. With the edge of the protective sheet The bundling tie band or tie straps or the like should be those provided integrally or separately the.

    The tracking frame is integrated with a horizontal portion of any appropriate shape including a bar shape or a plate shape between right and left sides, and is symmetrical with respect to at least the horizontal center of the horizontal portion. Two diving rods for avoiding the tension of the sheet tension are directed in the same direction as the towing head frame or the towing head frame protruding in the same direction and are in a mutually parallel posture or It follows one of the widened orientations following the divergent shape and rises at a relatively small angle of 1 to 20 degrees, preferably around 15 degrees with respect to the follower frame plane, It can be drawn and formed into a straight bar shape that reaches the vicinity of the lower base of the connecting frame developed in a shape or is slightly longer than that.

    The undercarp is pulled under each of the sheet stretching strings stretched in the direction between the beams between the portal skeletons when the sheet stretching tool is pulled and moved on the portal skeleton in the ridge direction. The rear end of the towing head frame or the one provided on the towing head frame exceeds the upper side of the connecting part for the towing rope and protrudes into the following frame. It should be formed in the shape of a straight bar that is inclined at a predetermined angle so as to reach the upper side of the vicinity of the tip side of the other submersibles installed. It is desirable to form a straight bar inclined at a predetermined angle so as to reach the upper side of the bundle-like portion of the sheet connected to the connection mechanism.

    The connecting frame follows the state in which the connecting frame is pivotally connected to the rear end of the following frame, and the leading frame for towing or towing is applied to the bundled portion of the sheets connected by the integrally formed connecting mechanism. It serves to transmit the traction input applied to the top frame for use, and is formed in a substantially trapezoidal shape having an upper base that substantially coincides with the lower base of the follower frame, and between the upper base and the lower base of the follower frame. It is assumed that a hinge mechanism is provided, and a connecting mechanism that temporarily attaches and enables the bundled portion of the sheet to be undetachable at an appropriate position from the upper base to the lower base.

    The attachment mechanism temporarily attaches the bundled portion of the sheet to the appropriate position of the attachment frame, and each of the leading frame for towing or the leading frame for towing, the follower frame and the connecting frame sequentially from the leading side, While moving in the direction of the ridge on the portal skeleton body and going under each sheet tension string, firmly binds the bundled parts of the sheets against the generated friction force so that they can not be removed, When it has finished moving to the other end side in the ridge direction and removes the bundled portion of the sheet from the sheet tensioning tool, it functions to be able to be removed relatively easily, and a binder In addition to those having a fastener using a spring mechanism such as a clip or a clip, or having a retaining mechanism such as a buckle, as shown in the examples described later, Between the right and left sides, place a sheet folding rod parallel to the top and bottom sides.

An auxiliary frame for sandwiching, in which the folds are integrated horizontally, the upper base is loosely fitted to the sheath tube, and the lower base, which is the same end, is on the side opposite to the side on which the dive heel projects. It can be connected so as to be rotatable so as to have a suspended arrangement.

    The hinge mechanism can be bent in a fixed direction between the leading frame for towing or the rear end of the leading frame for towing and the front end of the following frame, and between the rear end of the following frame and the front end of the connecting frame. It is possible to form a chain-like or annular coupling fitting integrally at one end and connect or loosely fit the other end to this. In order to easily regulate the bending direction, bending range, etc., one or both of the connecting parts have a hook-shaped part as a shaft core, and a sheath tube is attached to it to form a hinge part, or a separate shaft A hinge with a core part should be joined across both of the connecting parts, and the tip of the dive rod is integrated in place so that it does not interfere with the seat tensioning tool itself, the seat connection part, etc. Left and right near the upper bottom of the formed follower frame and connecting frame At least one of the two, preferably both, bends to the side where each follower frame and the connecting frame are extended in the same plane, and on the side where the diving rod for avoiding the sheet tension string is projected. It is desirable to have a bending restricting locking portion projecting so as to restrict.

The sheet can be stretched between all or part of the skeleton body between the beams in the direction of the beam and the sheet stretch string, and serves to form a sheet covering the interior of the greenhouse. For various special purposes such as reflective sheets and sunscreen sheets that have been surface-treated and colored in addition to various transparent so-called agricultural vinyl sheets that will be used and developed and provided in the future for seed greenhouses. It includes all types of sheet-like materials that can be used by being attached to the portal skeleton, such as sheets that are employed, or sheet-like sheets such as cold chills, nonwoven fabrics, and nets.
