Description

  The present invention relates to a sheet presser for an agricultural and horticultural house, and more particularly, to a sheet presser used to prevent the shape of a sheet retained by a framework of an agricultural and horticultural house from being deformed.

  As schematically shown in FIG. 4, the agricultural and horticultural house is made by stretching a sheet 2 such as a vinyl chloride resin sheet on a framework 1 assembled in a predetermined shape. Further, for the convenience of adjusting the room temperature or the like, an elevating member 3 for turning up the seat 2 to form an opening may be provided. In such an agricultural and horticultural house, the sheet presser 4 is used to prevent the sheet 2 from fluttering or losing shape due to being blown by the wind.

  In the agricultural and horticultural house of FIG. 4, the sheet presser 4 includes a rope 5 such as a string or a rope stretched on the sheet 2 so as to surround a portion extending from the upper part to the side part of the sheet 2, and the above A support body 6 made of a shaft or pipe material supported by an anchor 61 is provided at the lower part of the house, and the end of the rope body 5 is tied to the support body 6 to give a constant tension to the rope body 5. It is connected to the support 6. Reference numeral 51 denotes a knot formed at a tied portion of the cord body 5.

  In this type of agricultural and horticultural house, when the sheet 2 is turned up by the elevating member 3, when the cable body 5 is naturally loosened, or when necessary, the knot 51 is unrolled to loosen the cable body 5, The work of unwinding the knot 51 from the cable body 5 to the support body 6 and applying tension is performed manually. However, it takes a lot of time and labor to manually tie the cable body 5 to the support body 6 or loosen the cable body 5 by releasing the knot 51. In particular, in a house with a long length, since the cable bodies 5 are stretched at many places, the work takes a lot of time and labor.

  Therefore, the applicant of the present application uses the clamper 7 shown in FIG. 5 in place of the work of binding the cable body 5 to the support body 6 or loosening the cable body 5 by loosening the knot 51 of the cable body 5. It has been proposed to simplify the work of applying tension to the body 5 and releasing the tension by releasing the tension (actual application 2003-002771: actual climbing 3097850). This clamper 7 is formed by connecting two metal rings 8 and 9 formed in a substantially rectangular shape by metal bands 10 and 10 so as to be slidable in an overlapping state. In this clamper 7, a ring that is locked to the support body 6 by being folded back in a loop shape into three openings 71, 72, 73 formed by sliding the two ring bodies 8, 9 to be displaced. In the state where the two overlapping portions 53 of the end of the cable body 5 forming the section 54 meander and are slidably inserted, the end of the cable body 5 is pulled upward to give a tensile force to the cable body 5 Then, the two-layer overlapping portion 53 inserted through the three openings 71, 72, 73 is fixed by the clamper 7 so as not to slip. Moreover, in the clamper 7, the two-sheet overlapping portion 53 of the cord body 5 inserted in a meandering manner through the three openings 71, 72, 73 is loosened and the two-sheet overlapping portion 53 is slid to be applied to the cord body 5. The cable body 5 can be loosened by releasing the applied tensile force. The use of the clamper 7 eliminates the need to tie the cable body 5 to the support body 6 or to loosen the cable body 5 by loosening the knot 51 and to connect the cable body 5 to the support body 6. The time and effort required to complete the process can be greatly reduced.

  However, in the sheet presser using the clamper 7 described with reference to FIG. 5, when the tensile force is applied to the cable body 5 or the tensile force of the cable body 5 is released to loosen the cable body 5, the clamper 7 is held with one hand, and the two stacked portions 53 of the cable body 5 inserted in a meandering manner into the three openings 71, 72, 73 of the clamper are held and loosened with the other hand, It is necessary to shorten or lengthen the entire length of the rope body 5 by sliding the sheet stacking portion 53. However, work that requires the use of both hands, such as when holding a farm tool in one hand, can be cumbersome because it must be done after the farm tool is once placed on the ground. It was discovered.

  Therefore, the inventor of the present application should be able to apply tension to the rope body and to loosen the rope body by simply pulling the rope body with one hand without holding the clamper by hand. The present invention was made with the intention of.

  Therefore, the present invention performs an operation of applying a tensile force to the cable body holding the sheet to tension the cable body or releasing the cable body to loosen the cable body with one hand. An object of the present invention is to provide a sheet presser for an agricultural and horticultural house that can be used.

  Another object of the present invention is to provide a clamper at low cost by reducing the number of components of the clamper as much as possible when the clamper is used to maintain a state in which a tensile force is applied to the cable body.

  The agricultural and horticultural house sheet retainer according to the present invention is stretched on a sheet retained by the framework of the agricultural and horticultural house, and its end is connected to a support provided at the lower part of the house. A belt-like cord body, the support body, and a clamper for connecting the cord body to the support body. Further, the clamper comprises a clamp body having a hook portion that is locked to the support, a transverse portion that extends in the lateral direction, and a support guide portion that is connected to the transverse portion and extends in the longitudinal direction, and the clamper body. And a clamper auxiliary body that is attached to the support guide portion and is capable of moving toward and away from the traversing portion. And the said clamper auxiliary | assistant is extended over the U-shaped bending part formed by bending the said cable body in a U shape, and the cord body winding part latched by the U-shaped bending part, and the said cable body The loop formed by bending the loop portion formed by bending the U-shaped bent portion and the edge thereof is formed between the traversing portion and the loop inserted through the gap space. A cord pressing portion for extending across the cord weight or location formed at the base of the section and pinching the cord weight or location by cooperation with the traversing portion, and the cord winding portion and the cord The pressing part is connected so as to be able to approach and separate, and the cable body winding part is pulled up by the tensile force applied to the U-shaped bend part of the cable body, so that the cable body pressing part becomes the position of the cable weight and the traverse part The U-shaped bend when the nip is clamped together And a flexible portion having elasticity to resiliently urging in a direction away from the overlap point.

  With this configuration, the end of one side is fixed to the ground on one side of the sheet retained by the framework using an appropriate means, and the band-like cord body drawn on the opposite side on the sheet is The U-shaped bent portion at the other end is locked to the rope body winding portion of the clamper auxiliary body attached to the clamper main body having the hook portion locked to the support body, and the transverse portion of the clamper main body and If you pull the loop part of the cable body inserted into the gap space between the clamp body and the clamp pressing part to increase the pull-out width of the loop part from the gap space, The effective length of the cable body drawn by the wire is shortened, and a tensile force is applied to the cable body, so that the cable body is tensioned and exerts an action of pressing the sheet. When a tensile force is applied to the cord body in this way, the clamper auxiliary body is pulled up by the cord body, and the cord pressing portion cooperates with the transverse portion of the clamper main body so that the cord weight at the base of the loop portion of the cord body is obtained. Since the portion is pinched, the effective length of the cord body (the length of the cord body used to hold the sheet) is kept constant by the clamper and the cord body is kept in tension without being loosened. In addition, when the cord body is kept in tension as described above, the cord-shaped winding portion of the clamper auxiliary body is wound around the U-shaped bent portion of the corder auxiliary body by the action of the flexible portion. Even if the cord holding the seat expands or contracts due to the displacement of the weight or the influence of changes in temperature because it is elastically biased in the direction away from the weight, it will occur at that time. The expansion / contraction allowance is absorbed by the displacement of the cable body winding part, and the situation where the cable body is loosened or excessively tensioned is suppressed. In addition, when the cord body is in tension, pulling the loop portion of the cord body to further increase the pull-out width of the loop portion from the gap space can further tension the cord body accordingly. is there.

  On the other hand, when loosening a tensioned cable body, pull the edge of the cable body extending from the weight of the cable clamped by the clamp body pressing part of the clamper auxiliary body and the transverse part of the clamper main body. Pull the cord out of the pinched area. In this way, the loop portion of the cord body disappears and the cord body comes out of the pinched portion, so that the fixing state of the cord body by the clamper is released and the tensile force applied to the cord body until then is released. The cable body is released and released.

  The above-mentioned operations to tension the cord body and loosen the strained cord body are operations performed by pulling the loop portion of the cord body or the edge of the cord body, so these operations are performed using only one hand. Can be done easily and quickly.

  In the present invention, the clamper main body is formed by bending one metal wire into a gate shape to form one traversing portion and two left and right support guide portions, and the hook portion is substantially U-shaped. It is desirable that the left and right two support guide portions are connected to each other by bending in a letter shape. According to this, since it is possible to manufacture the clamper main body simply by bending a single metal wire, the required number of components of the clamper main body is suppressed to the minimum.

  In the present invention, the clamper auxiliary body is formed with a cord wrapping portion and a cord pressing portion that extend along each other by bending one other metal wire into a lateral U shape, and the flexible portion Is formed by bending the other metal wire in the folding direction with respect to the cable body hooking part and the cable body pressing part at a portion corresponding to one end of the cable body winding part and the cable body pressing part. It is desirable that According to this, since it is possible to manufacture the clamper auxiliary body simply by bending one separate metal wire, the required number of components of the clamper main body is suppressed to the minimum. Moreover, coupled with the fact that the clamper main body can be manufactured by simply bending a single metal wire as described above, the number of components required for the clamper can be minimized and the price can be kept low. It becomes possible.

  In the present invention, the clamper auxiliary body includes a first fitting portion connected in a folded manner to each of the other end portion of the cord body winding portion and the other end portion of the cord body pressing portion; A second fitting portion formed by a bent portion at the base of the flexible portion, and the first fitting portion and the second fitting portion are separately provided on the left and right support guide portions of the clamper main body. It is desirable that it is slidably fitted. This also makes it possible to keep the required number of components of the clamper to a minimum and keep the price low.

  As described above, the sheet presser of the agricultural and horticultural house according to the present invention can easily and quickly tension or loosen the rope drawn around the sheet using only one hand. Therefore, there is a convenience that the operator can easily and quickly tension or loosen the rope while holding the farm tool or the like in one hand. Therefore, even when the cable body 5 is stretched in many places of a long house, the work of tensioning or loosening the cable body is performed in a short time without much effort. The outstanding effect of being able to do it is produced.

  FIG. 1 is a perspective view showing a use state of a sheet presser according to an embodiment of the present invention. 2A is a plan view of the clamper 100, and FIG. 2B is a front view thereof. Further, FIG. 3A is an operation explanatory diagram in a state where the cord body 5 is tensioned, and FIG. 3B is an operation explanatory diagram in a state where the cord body 5 is loosened.

  As shown in FIG. 1, the sheet presser according to the embodiment is formed from the upper part of the sheet 2 held by the support 6 disposed in the lower part of the house described in FIG. 4 and the skeleton 1 described in FIG. 4. A belt-like cord body 5 stretched on the sheet 2 so as to surround a portion extending over the side portion, and a clamper 100, and the cord body 5 is formed of the sheet 2 held by the skeleton 1. One end is fixed to the ground on one side using an appropriate means, and is drawn around to the opposite side on the sheet 2 (see FIG. 4). It is held by a clamper 100 connected to the support 6. The cord body 5 employs a band-shaped resin band having a width of about 5 cm, and the resin band is provided with parallel stripes 52 as shown in FIG. 5 at regular intervals. The thickness of the resin band is a little thicker at the location where the line 52 is formed, and this line 52 exhibits the action of suppressing the expansion and contraction of the resin band.

  As shown in FIG. 1 or FIG. 2, the clamper 100 includes a clamper main body 110 and a clamper auxiliary body 150, and the clamper main body 110 and the clamper auxiliary body 150 are both formed by bending a single metal wire. It is.

  That is, the clamper main body 110 includes a straight traverse portion 112 and a pair of left and right straight support guide portions 113 that are connected to both ends of the traverse portion 112 and bent at a right angle and extend in the vertical direction. 113, and hook portions 114, 114 having elasticity of the same shape are connected to the lower ends of the left and right support guide portions 113, 113, respectively, and are bent. In this embodiment, the hook portion 114 has a recess having a width that can receive the support body 6 in a loosely fitted state, whereas the opening width dimension of the receiving port 115 is the diameter dimension of the support body 6. Shorter than. Therefore, after the support body 6 is separately inserted into the receiving port 115 and the left and right hook portions 114 and 114 are locked to the support body 6, the hook portions 114 and 114 can swing with respect to the support body 6. Despite being, there is an advantage that the situation that the hook part 114 easily falls off the support 6 does not occur.

  On the other hand, the clamper auxiliary body 150 includes a lower cable body winding part 151 and an upper cable body pressing part 152 that extend straight along each other, and the cable body winding part 151 and the cable body pressing part 152. A first fitting portion connected in a folded manner to each of the flexible portion 153 connecting the one end portions, the other end portion of the cord winding portion 151 and the other end portion of the cord pressing portion 152. 154 and 155, and a second fitting portion 156 provided at the base of the flexible portion 153. More specifically, the cable body winding part 151 and the cable body pressing part 152 are inclined upward or downward so that the distance between the cable body winding part 151 and the cable body pressing part 152 increases as the distance from the connecting part with the flexible part 153 is increased. In the direction of approaching each other (the direction of narrowing the opening angle between the two) with the deformation of the flexible portion 153, with the posture in such a natural state as a neutral position, It can be displaced in a direction in which the opening angle between the two is widened. Further, the flexible portion 153 is displaced when the cord body winding portion 151 and the cord body pressing portion 152 are moved closer to each other and when the cord body winding portion 151 and the cord body pressing portion 152 are separated from each other. When displaced in the direction, it has elasticity that can return them to the neutral position. Further, the first fitting portions 154 and 155 are formed by bending the metal wire in a folded shape at the ends of the cord body winding portion 151 and the cord body pressing portion 152, whereas the second fitting portion Reference numeral 156 denotes a bent portion at the base of the flexible portion 153. Then, the first fitting portions 154 and 155 are slidably fitted to the support guide portion 113 on one side of the clamper main body 110, and the second fitting portion 156 is fitted to the support guide portion 113 on the other side of the clamper main body 110. The clamper auxiliary body 150 is attached to the traversing portion 112 of the clamper main body 110 so as to be able to approach and separate by being slidably fitted. In addition, the 1st fitting parts 154 and 155 and the 2nd fitting part 156 are formed in the state wound in the range exceeding the half circumference of each support guide part 113 on either side, and employ | adopt such a structure. Therefore, the clamper auxiliary body 150 is caught by the traversing portion 112 and the hook portion 114 of the clamper main body 110 so as not to fall off the clamper main body 110.

  Next, an example of a procedure for stretching the cable body 5 together with the action of the sheet pressing tool will be described mainly with reference to FIG.

  The other end portion of the belt-like cord body 5 is fixed to the ground on one side of the sheet shaped by the framework using an appropriate means and the other end of the belt-like cord body 5 is drawn on the opposite side of the sheet. The U-shaped bent portion 55 formed by bending in a U-shape is passed through the gate-shaped clamper main body 110 on the lower side of the clamper auxiliary body 150 and is wound upward on the cord body winding portion 151 of the clamper auxiliary body 150. After that, the loop portion 56 formed by bending the cord body 5 between the U-shaped bent portion 55 and the end edge 57 is used as the traversing portion 112 of the clamper main body 110 and the cord body pressing portion 152 of the clamper auxiliary body 150. The edge 57 of the cable body 5 is pulled out to the front side by being inserted into the gap space S (see FIG. 1) formed between the two. At this stage, the cord body winding portion 151 of the clamper auxiliary body 150 extends across the U-shaped bent portion 55 of the cord body 5, and the cord pressing portion 152 is formed at the base of the loop portion 56 of the cord body 5. It extends across the part i.

  In the next stage, when the loop portion 56 of the cable body 5 inserted through the gap space S is pulled up to increase the pull-out width of the loop portion 56 from the gap space S, the sheet width matches the pull-out width. The effective length of the cable body 5 routed upward is shortened, and a tensile force is applied to the cable body. Therefore, the cable body 5 exerts an action of tensioning and pressing the sheet.

  When the tensile force is applied to the rope body 5 in this way, as shown in FIG. 3A, the clamper auxiliary body 150 is pulled up by the rope body 5 so that the rope body pressing portion 152 and the transverse portion 112 of the clamper main body 110 are shared. Since it works and pinches the root weight of the loop portion 56 of the rope body 5, the effective length of the rope body 5 is kept constant by the clamper 100 without the rope body 5 being loosened, and the rope body 5 is kept in tension. Be drunk.

  Further, when the cable body 5 is kept in tension as described above, the cable body winding part 151 of the clamper auxiliary body 150 is displaced upward against the urging by the flexible part 153. The cord winding portion 151 elastically urges the U-shaped bent portion 55 of the cord body 5 downward as indicated by the arrow D by the reaction force. Therefore, even if the cable body 5 holding the sheet expands and contracts due to the displacement of the position or the influence of the temperature change, the expansion / contraction allowance generated at that time is below or above the cable body winding portion 151. The situation that the cable body 5 is loosened or excessively strained due to being absorbed by the displacement to the heel is suppressed. In addition, when the cord body 5 is in tension, the loop portion 56 of the cord body 5 is pulled up as shown by an arrow U in FIG. 3A to further extend the pull-out width of the loop portion 56 from the gap space S. If it is increased, it is possible to further strain the cord body 5 accordingly.

  When loosening a tensioned cable body, the cable body 5 is pulled out by pulling the edge 57 of the cable body 5 forward or upward as indicated by an arrow P in FIG. As a result, the loop portion 56 of the cord body 5 disappears, and the cord body 5 escapes from the pinched portion between the traversing portion 112 of the clamper main body 110 and the cord body pressing portion 152 of the clamper auxiliary body 150. The fixed state of the cable body 5 by 100 is released, the clamper auxiliary body 150 is lowered as indicated by the arrow Y, and the tensile force applied to the cable body 5 until then is released and the cable body is loosened.

  Here, the operation for tensioning the cord body 5 and the operation for loosening the strained cord body 5 as described above are operations performed by pulling the loop portion 56 of the cord body 5 or the edge 57 of the cord body 5. These operations can be performed easily and quickly using only one hand.

It is the perspective view which showed the use condition of the sheet pressing tool which concerns on embodiment of this invention. (A) is a top view of a clamper, (B) is the same front view. (A) is action explanatory drawing in the state which strained the rope body, (B) is action explanatory drawing in the state which loosened the rope body. FIG. It is a schematic perspective view of the principal part which showed the use condition of the prior art example.
