Description

  The present invention relates to a sheet retaining clip for fixing a sheet-like object such as a sheet or a net to a support in an orchard or a greenhouse.

  In general, when supporting orchards or greenhouses are placed around the orchards or greenhouses, and sheet materials such as sheets and nets are stretched around the orchards and greenhouses, the sheet materials are covered with sheets. In addition, a sheet having a substantially C-shaped cross section is pressed against a portion where the structural material and the sheet-like material are in contact with each other, and the sheet-like material is sandwiched between the outer peripheral surface of the structural material and the inner surface of the clip. There has been proposed a method for fixing a material to a structural material. Such a clip has a simple structure, but the C-shaped opening end of the clip is pushed into the support column while contacting the sheet-like object, and the sheet-like object has problems such as scratches and tears. It was easy and difficult to remove once attached.

  Therefore, in order to solve this problem, an escape portion that bends toward the center of the substantially C-shaped clip body is formed, and arms extend from both sides of the escape portion in parallel to each other, and the tips of both arms There has been proposed a clip in which connecting pieces that are flexibly connected to each other are provided and the connecting pieces are connected by a thin portion. (For example, refer to Patent Document 1).

This clip is used to hold the connection piece in a bent position where it is difficult to return to the outside by interposing between the arms so that the connection piece bends at the center thin wall part after the clip body is fixed to the column etc. In this bent position, the outer end surface of the connecting piece on the arm side is brought into contact with the arm, and the inner end surface provided with the connecting piece for connecting the connecting pieces is opposed to each other. The arm is pushed outward, the clip body is squeezed inward, and the object to be secured between the support post and the like can be further strongly clamped.
Japanese Utility Model Publication No. 52-23477

  However, the above clip has the following problems. That is, the initial state of the clip is a state in which the connecting piece is bent outward at the central thin portion, and when the connecting piece is interposed between the arms so as to be bent inward, the connecting piece is removed. If it is held in a bent position where it is difficult to return, it may cause problems due to excessive force applied to the thin wall part during this intervention process, and the same problem may occur when removing the connection piece. When the degree of bending after the holding is small, the connection piece may return to the outside when vibration or impact is applied, which is insufficient in that respect.

  The present invention eliminates the above-mentioned problems, and in orchards and plastic greenhouses, it is possible to firmly fix a sheet-like material such as a net member or a vinyl sheet to a support and provide a sheet retaining clip that is difficult to come off. It is.

  In order to achieve the above object, the present invention is configured as follows. That is, the clip according to the present invention has two sandwiching pieces opposed to each other and a connecting piece that connects each other at the center of the sandwiching piece, and the other through the connecting piece from the tip of one holding piece. This is a sheet retaining clip that sandwiches a sheet-like material between the sandwiching surface and the support column, with the inner wall surface up to the distal end of the sandwiching piece as the clamping surface. Bendable connecting pieces are provided opposite to each other, and their tip portions are connected to each other via a thin portion, and the thin portion is moved back and forth with respect to the sandwiching surface, whereby the tip of the sandwich piece The interval between the parts is enlarged and reduced, and the thin part is fixed by the fixing part, so that the interval between the tip parts of the holding pieces is kept constant.

  According to the present invention, by moving the thin portion back and forth with respect to the sandwiching surface, the interval between the tip portions of the sandwiching piece is expanded and contracted, and the thin portion is fixed by the fixing portion. Since the distance between the tip ends is kept constant, after the sheet-like object is clamped between the clamping surface and the column, the thin-walled part is moved to widen the gap between the tip parts of the clamping pieces. In this state, by fixing the thin portion with the fixing portion, a force acts on the clamping surface in the direction of closing inward, and the sheet-like material can be firmly clamped, and it is difficult for the fixing portion to come off.

  In the sheet retaining clip according to the present invention, the fixing portion includes an engaging piece formed on one connecting piece and an engaging piece formed on the other connecting piece and engaged with the engaging piece. If the engaging piece is engaged with the locking piece when the thin part is moved toward the clamping surface, the thin part can be fixed by moving the thin part. Fixing of the thin wall portion is facilitated.

  Further, in the sheet retaining clip according to the present invention, the holding clip includes two opposing holding pieces and a connecting piece that connects each other at the center of the holding piece, and the connecting piece is connected from the tip of one holding piece. A sheet retaining clip that sandwiches a sheet-like material between the sandwiching surface and the column with the inner wall surface to the tip of the other sandwiching piece as a sandwiching surface, Connection pieces that can be bent in the distal direction are provided opposite to each other, and the distal ends thereof are connected to each other via a thin portion, and the thin portion is moved forward and backward with respect to the sandwiching surface, thereby If the interval between the tip portions of the pieces is expanded or reduced, the sheet-like object is sandwiched between the sandwiching surface and the support column by fixing the thin portion at an appropriate position, and the sandwiched state is Can be maintained.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  That is, FIG. 1 is a front view showing an embodiment of the sheet stopper clip according to the present invention, FIG. 2 is a top view of the same sheet stopper clip, and FIG. 3 is a side view of the same sheet stopper clip. 4 is a cross-sectional view taken along the line AA in FIG. FIG. 5 is a perspective view showing a use state of the sheet stopper clip according to the present invention, FIG. 6 is a perspective view showing another use state, and FIG. 7 is a front view showing a second embodiment of the sheet stop clip according to the invention. It is.

  In the drawings, 1 is a clamping piece that faces each other, 2 is a connecting piece that connects the clamping piece 1, 3 is a clamping surface formed on the inner wall surface of the clamping piece 1, The sheet-like material 6 is sandwiched between the clamping surface 3 formed mainly on the clamping piece 1 and the outer surface of the support column 5.

  First, the column 5 and the sheet-like material 6 are provided to prevent rain, pests, and birds and beasts from entering the cultivated materials such as trees and vegetables used in orchards and greenhouses. In general, a sheet member 61 that is transparent or translucent and mainly intended to prevent rain, and a net member 62 that mainly prevents the entry of pests and birds and beasts are used as the sheet 6.

  The sheet member 61 is formed by forming a synthetic resin having transparency or translucency such as polyolefin resin such as polyethylene or polypropylene, polyester resin such as polyethylene terephthalate or polylactic acid, polyvinyl chloride, or the like into a sheet. It can be used appropriately depending on the size and thickness. The net member 62 is formed by forming a linear body or band made of a synthetic resin such as polyethylene, polypropylene, polyester, nylon resin, polyester, or a natural resin such as hemp or cotton into a mesh shape, and is a target. It can be used appropriately depending on the strength required for pests and birds and beasts or the size of the mesh.

  Moreover, the support | pillar 5 is generally pipe-shaped things, such as a steel pipe and an aluminum pipe, and these are arrange | positioned in an orchard or a vinyl house, combining these suitably in the vertical direction and a horizontal direction, and a sheet member, a net member, etc. A sheet-like object 6 is stretched. The material of the column 5 is not limited to the above. For example, a steel pipe subjected to a rust prevention treatment such as galvanization, stainless steel, or the like, depending on the length of the column 5 and required strength and durability, as appropriate. Can be used. In addition, the cross-sectional shape of the column 5 is circular in this embodiment, but may be elliptical or polygonal such as a quadrangle or a pentagon.

  Subsequently, as shown in FIGS. 1 to 3, the sandwiching piece 1 is connected to each other at the center by the connecting piece 2, and is opposed to the leading end portion 11 of the sandwiching piece 1 via the connecting piece 2. The inner wall surface up to the tip 11 of the sandwiching piece 1 is the sandwiching surface 3. Accordingly, when the interval between the base end portions 12 and 12 of the sandwiching piece 1 is enlarged or reduced, the interval between the distal end portions 11 and 11 is enlarged or reduced with the connecting piece 2 as a fulcrum. In this embodiment, the sandwiching surface 3 is formed in a semi-cylindrical shape, but may be an elliptical shape or a polygonal shape such as a quadrangle or a pentagon as long as it is attached to the support column 5. Note that the central portion of the sandwiching piece 1 does not only refer to the vicinity of a position that is equidistant from the distal end portion 11 and the proximal end portion 12 of the sandwiching piece 1, but the sheet retaining clip P is the proximal end portion of the sandwiching piece 1. In the range in which the interval between 12 and 12 is expanded and contracted and attached to the column 5, a portion close to the distal end portion 11 or the proximal end portion 12 is also included.

  Further, on the outer surface of the clamping piece 1 on which the clamping surface 3 is formed, a hooking portion 13 for hanging the net member 62 is provided. The hanging portion 13 has a substantially T-shaped cross section, a support portion 14 erected on the outer surface of the holding piece 1, and a hanging member 15 that extends substantially in parallel with the holding piece 1 from the tip of the support portion 14. Consists of. In this embodiment, the tip of the hanging member 15 is bent toward the holding piece 1 so that it is difficult to come off when the net member 62 of the sheet-like material 6 is hung on the hanging portion 13.

  Further, the sandwiching piece 1 is formed thicker than the connecting piece 2. Accordingly, when the interval between the base end portions 12 and 12 of the sandwiching piece 1 is expanded and contracted, the sandwiching piece 1 is hardly deformed, and the relatively thin connecting piece 2 is mainly elastically deformed, and the end portion 11 , 11 is expanded and contracted. Further, as shown in FIGS. 1 and 4, a band-shaped reinforcing portion 16 is formed on the inner surface side of the base end portion 12 of the sandwiching piece 1 along the central portion via the connecting piece 2. Accordingly, the connecting piece 2 is easily elastically deformed, and the strength of the connecting piece 2 can be maintained by the reinforcing portion 16.

  Connection pieces 41 are foldably attached to both ends of the base end portion 12 of the sandwiching piece 1. In this embodiment, the connection portion between the base end portion 12 and the connection piece 41 is formed thin, and it is easy to bend at this thin portion. The distal ends of the connection pieces 41 are connected to each other by a thin portion 42. By moving the thin portion 42 back and forth with respect to the sandwiching surface 3, the distance between the base end portions 12 and 12 of the sandwiching piece 1 is expanded and contracted, and the distal end portions 11 and 11 of the sandwiching piece 1 are interlocked with the expansion and contraction. The interval of is expanded.

  On the inner side surface of the connection piece 41, a bending suppression piece 43 protrudes, and this tip is bent toward the adjacent holding piece 1. Thus, when the thin portion 42 is moved toward the sandwiching surface 3, the tip of the bending suppressing portion 43 of the connection piece 41 is brought into contact with the sandwiching piece 1, so that the thin portion 42 moves toward the sandwiching surface 3. It is made not to move any more.

  In addition, a locking piece 44 is provided on the outer surface of one connection piece 41, and an engagement piece 45 that is engaged with the locking piece 44 is provided on the other connection piece 41. Forming. Then, when the thin portion 42 is moved toward the sandwiching surface 3, the locking piece 44 and the engaging piece are engaged with each other at a position where the two connecting pieces 41 are almost horizontal, and the thin portion 42 is It is designed to be fixed.

  The locking piece 44 has a triangular cross-sectional shape standing from one connection piece 41, and the surface of the engagement piece 45 stands substantially perpendicular to the connection piece 41. At the tip of this surface, a flange 46 protrudes toward the engagement piece 45, and the engagement piece 45 is locked to the flange 47.

  The engagement piece 45 has a substantially T-shaped cross-section standing from a connection piece 41 different from the above, and the outer surface has an elliptical shape having a gently inclined surface recessed toward the center. A pressing surface 48 is formed, and the central portion of the pressing surface 48 is disposed on the moving path of the thin portion 42. Thus, when the engagement piece 45 is moved toward the sandwiching surface 3, the thin portion 42 is also moved in conjunction with the connection piece 41. In addition, the operator can easily move the thin portion 42 by pressing the pressing surface 48 toward the clamping surface 3 together with the anti-slip rib provided on the pressing surface 48.

  Next, an operation procedure for sandwiching the sheet-like object 6 between the sandwiching surface 3 of the sheet retaining clip P and the support column 5 using the sheet retaining clip P according to this embodiment will be described. First, the sheet-like object 6 is held on the surface of the support column 5. Next, in the clamping piece 1 of the sheet retaining clip P, both outer side surfaces on the base end side are pressed inward so that the interval between the base end portions 12 and 12 is narrowed. Thereby, the space | interval between the front-end | tip parts 11 of the clamping piece 1 expands. In this embodiment, as shown in FIG. 1, the position of the thin portion 42 in the initial state is a position far from the clamping surface 3 with respect to the position where the two connection pieces 41 are substantially horizontal. When the interval between the base end portions 12 and 12 is narrowed, the position of the thin portion 42 is farther from the sandwiching surface 3 as shown in FIG. In addition, a plurality of ribs 49 are provided in parallel on the outer side surface on the proximal end side of the sandwiching piece 1 so as to prevent slipping during the pressing operation.

  Subsequently, the distance between the base end portions 12 and 12 is reduced by the pressing operation described above, and the interval between the tip end portions 11 and 11 of the sandwiching piece 1 is increased to approximately the same as the outer diameter of the support column 5, and the sheet retaining clip P is attached to the column 5, and the sheet-like object 6 is sandwiched between the clamping surface 3 and the column 5. In this embodiment, the inner diameter of the clamping surface 3 is formed to be slightly smaller than the outer diameter of the column 5, and when the sheet retaining clip P is attached to the column 5, the clamping surface 3 is pressed so as to be expanded from the column 5. Therefore, the sheet-like object 6 sandwiched between the support columns 5 can be more firmly sandwiched by the repulsive force against the pressing.

  Even if the inner diameter of the clamping surface 3 is set to be substantially the same as the outer diameter of the support column 5 and the sheet retaining clip P is attached to the support column 5, the sheet-like material 6 sandwiched between the clamping surface 3 and the support column 5 is used. Thus, since the outer diameter of the support column 5 becomes the same as that, the sheet retaining clip P can sandwich the sheet-like object 6 more firmly by the same effect as described above. Further, the front end portion 11 of the sandwiching piece 1 is extended outward in the direction in which the distance between the front end portions 11, 11 is increased, and when the sheet retaining clip P is attached to the column 5, the sandwiching surface 3 is attached to the column 5. It is designed to fit easily.

  Subsequently, when the pressing surface 48 of the engagement piece 45 is pressed toward the clamping surface 3, the thin portion 42 also moves in conjunction with the two connection pieces 41 as shown in FIG. The locking piece 44 and the engaging piece 45 are engaged with each other at a position where the substantially flat state is reached, and the position of the thin portion 42 is fixed. As a result, the sheet retaining clip P is fixed in a state in which the distance between the base end portions 12 and 12 of the sandwiching piece 1 is most widened. Therefore, a force that narrows the distance between the distal end portions 11 and 11 acts effectively. And the sheet-like object 6 can be clamped efficiently.

  Further, when the sheet-like object 6 is the net member 62, as described above, it may be sandwiched between the sheet retaining clip P and the column 5, but as shown in FIG. 5 and the sheet-like object 6 can be fixed by hanging the mesh of the net member on the hanging portion 13 of the holding piece 1. In particular, when it is desired to open the mounting location of the net member 62 for a certain period, the net member 62 may be gathered at one end and hung on the mesh 13 to hold the open state. There is no need to desorb 62.

  Furthermore, after the sheet-like object 6 is fastened to the column 5 by the sheet-fastening clip P, a linear body such as a rope or a wire is attached to the hanging portion 13 of the holding piece 1 across the plurality of sheet-fastening clips P. The sheet-like material 6 can be made difficult to be blown by wind or the like.

  When removing the sheet retaining clip P from the support column 5, first, the thin portion 42 is moved outward from the clamping surface 3 to remove the engaging piece 45 from the locking piece 44. In this embodiment, in the connection portion between the connection piece 41 and the thin portion 42, the thickness of the connection piece 41 gradually decreases toward the thin portion 42. Thus, when the operator presses the vicinity of the thin portion 42 facing the clamping surface 3 outward, it is difficult for a finger or the like to be sandwiched between the two connection pieces 41.

  FIG. 7 is a front view showing a second embodiment of the sheet retaining clip according to the present embodiment. Compared with the sheet retaining clip P shown in FIG. 1, the sheet retaining clip P according to the second embodiment has a protrusion 17 on the surface where the retaining piece 44 is removed and the surface of the sandwiching piece 1 that faces the bending suppressing piece 43. 7 is different, and the others are the same as those shown in FIG.

  That is, the sheet retaining clip P shown in FIG. 7 moves the thin portion 42 toward the sandwiching surface 3 from this state, and the two connecting pieces 41 and 41 are arranged in a substantially straight line. 1 is widest and the inside of the clamping surface 3 is narrowed accordingly, so that a sheet-like object (not shown) is interposed between the clamping surface 3 and the support column (not shown). ) Can be clamped most firmly. When the thin portion 42 is further moved to the sandwiching surface 3 side, the inner surface of the sandwiching surface 3 is expanded, and when the bending suppression piece 43 and the projection 17 of the sandwiching piece 1 come into contact, the thin portion 42 is placed on the sandwiching surface 3 side. It cannot move any further.

  The inner diameter of the clamping surface 3 when the bending suppression piece 43 and the projection 17 of the clamping piece 1 are in contact is substantially the same as or slightly smaller than the outer diameter of the support column. Thereby, if the thin part 42 exists in the position from the state where the space | interval between the front-end | tip parts 11 and 11 of the clamping piece 1 was most expanded to the state where the bending suppression piece 43 and the protrusion 17 of the clamping piece 1 contact, The movement on the clamping surface 3 side is restricted by the bending suppression piece 43 and the protrusion 17, and the movement in the direction away from the clamping surface 3 results in a narrowing of the clamping surface 3 on which the columns and the like are arranged. Therefore, the sheet-like material can be firmly sandwiched between the sandwiching surface 3 and the support column, and the sandwiched state can be maintained. In addition, the protrusion 17 of the clamping piece 1 may not be provided, and the bending suppression piece 43 may be extended toward the clamping piece 1.

  When attaching the sheet retaining clip P to a column or the like, first press each other with the outer surface of the base end portion 12 facing inward so as to narrow the gap between the base end portions 12 and 12 of the sandwiching piece 1 shown in FIG. Then, the sandwiching surface 3 is widened and the position of the thin portion 42 moves in a direction away from the sandwiching surface 3. Subsequently, a column or the like is inserted into the sandwiching surface 3, and the thin piece 42 is in the state where the distance between the distal end portions 11, 11 of the sandwiching piece 1 is expanded most with the engagement piece 45 facing the sandwiching surface 3 side. It is pressed until it is further positioned on the clamping surface 3 side. Thereby, a sheet-like object is clamped between the support | pillar and the clamping surface 3, and the state can be maintained. In this state, the thin portion 42 is directly pressed away from the clamping surface 3 or the engagement piece 45 is pulled in the same direction to move the thin portion 42 to the position shown in FIG. If the distance between the two base end portions 12 and 12 is narrowed, the clamping surface 3 is widened, and the column and the sheet-like object can be removed from the sheet retaining clip P.
