Since the plate retainer having the above configuration can be easily detached and disassembled from the concave groove of the holder, the work for removing the vinyl sheet or the net from the frame of the house is also easy.

Next, an embodiment of how the resin sheet fixture according to the present invention is actually realized will be described. FIG. 2 is an exploded perspective view of a resin sheet mounting tool according to the present invention, which comprises a resin sheet holder 1, a band plate-shaped pressing plate 5, and a pressing device 6 for the pressing plate 5. This presser 6 is an example, and various shapes and structures are possible. When attaching a vinyl sheet or the like, the presser 6 is simply pushed onto the presser plate 5 while a part of the vinyl sheet 3 is pressed into the concave groove 2 of the holder 1 with the presser plate 5. At this time, except for the both ends of the presser 6, the holder 1 is not easily detached from the holder 1 because it is in a state of being submerged under the inward protruding ridge 7 a in the middle of the side wall 9 of the holder 1. As a result, the vinyl sheet 3 is sandwiched on the bottom plate 8 of the recessed groove 2 over the entire surface of the belt-like long pressing plate 5, so that the vinyl sheet is stably fixed and less likely to be damaged. In addition, the presser plate 5 can be given elasticity by forming a slightly curved shape.

3 (1) and 3 (2) are cross-sectional views showing various embodiments of the holder. (1) has the simplest cross-sectional shape and is characterized by U-shaped side walls facing each other. The point which has the inward protruding ridges 7 and 7 in the opening of the groove-shaped part 2 is the same as the case of the holder of FIG. 1 and FIG. 2 is a substantially M-shaped curved surface, whereas the concave groove side wall 9 of FIG. 3A is flat. In use, a belt-like pressing plate 5 is placed on the vinyl sheet 3 and pressed into the concave groove 2, and then the pressing device 6 is fitted on the pressing plate 5, Dive into the bottom. Both ends 6a of the V-shaped retainer 6 in FIG. 2 are bent in a U-shape or a U-shape, and the inwardly protruding ridge 7 is inserted into the U-shape or U-shaped recess 6b. It has become.

In order to fit the V-shaped presser 6 onto the presser plate 5, the V-shaped bent portion 6V and the small V-shaped portion 6v at one end are formed on the inwardly protruding ridges 7 and 7 on both sides of the groove 2. After fitting in the lower side, the V-shaped retainer 6 is expanded in the directions of the arrows a1 and a2, and the small V-shaped portion 6v at the other end is below the corresponding inwardly protruding ridge 7 of the groove 2. Just fit in. In the state of being fitted in this way, as described above, one of the inwardly protruding ridges 7 is inserted into the U-shaped or U-shaped depressions 6b at both ends of the V-shaped presser 6. The V-shaped presser 6 may have a configuration in which a wire with high elasticity is formed by bending, or may be molded from a synthetic resin. Alternatively, a metal plate may be press formed.

The holder shown in FIG. 3 (2) has a shape in which the side wall 9 shown in FIG. 3 (1) is raised and an inwardly protruding ridge 7a is formed in the middle. Insert the vinyl sheet 3, net, presser plate 5, and presser 6 in this order. Unlike the inward protruding ridges 7a shown in FIGS. 1 and 2, the inward protruding ridges 7a are projected to the same extent as the inward protruding ridges 7 in the opening, so that the presser plate 5 or the like may be detached. There are few. If a U-shaped or U-shaped bent portion 6a is provided at both ends of the presser 6, when the vinyl sheet 3 is obstructed as shown in FIG. 3 (2), a shape without the bent portion 6a is also possible. is there. In that case, since the V-shaped angle of the presser 6 can be expanded by using a simple operation jig, the handling operation is not particularly inconvenient. If a V-shaped plate 10 as shown in FIG. 4 is used in place of the presser 6 having the bent portion 6a, there is no possibility that the vinyl sheet 3 will be obstructed.

FIG. 4 and subsequent figures are pressers to be fitted to fix the presser plate 5 inserted into the holder as described above, and show various embodiments other than the V-shaped presser 6. The presser 10 of FIG. 4 has a shape in which a strip made of synthetic resin or metal is bent into a substantially V shape. And in the V-shaped bent portion and both ends of the V-shaped plate 10, relief recesses 11 and 12 for fitting the inward protruding ridges 7 and 7a as described above are formed. In use, when the V-shaped plate 10 is fitted on the pressing plate 5 after the vinyl sheet is pressed into the concave groove portion 2 of the holder with the pressing plate 5 as described above, the relief recess 11 of the V-shaped bent portion. One inward ridge 7, 7 a is inserted inside, and the other inward ridge 7, 7 a is inserted into the relief recess 12 at both ends. And like the said presser 6, it hold | maintains at a holder by the elasticity at the time of trying to close a V-shaped bending part.

FIG. 5 is a plan view of a state in which the vinyl sheet is attached to the holder with the V-shaped plate 10 in this manner, and the V-shaped plate 10 is mounted at a substantially constant interval. When the V-shaped plate 10 is attached to the holder 1, the V-shaped plate 10 is fitted in a state of being expanded in the directions of arrows a1 and a2, and then the expansion force in the directions of arrows a1 and a2 is released. In such a state, the vinyl sheet and the long pressing plate 5 in the form of a strip plate are interposed between the bottom plate 8 of the groove, and the elastic action is combined with the vinyl sheet and the net in the holder 1 stably. Retained. When detaching, the escape recesses 11 and 12 can be easily detached from the left and right inward protruding ridges 7 and 7a by spreading in the directions of the arrows a1 and a2.

FIG. 6 shows a vertical plate-like presser 13 that is mounted in the recessed groove 2 of the holder. In this state, the recessed recesses 14 and 14 are formed so that the inwardly protruding ridges 7 and 7a can be fitted to the side surfaces at both the left and right ends. In the case of this standing plate shape, unlike the V-shaped pressers 6 and 10 as described above, the elasticity in the direction in which the V-shaped bent portion is closed cannot be exhibited. Therefore, if necessary, cuts 15 and 15 are formed from the left and right ends toward the center so that the elasticity in the vertical direction can be generated.

Therefore, when the lower surface 16 of the upright plate-shaped presser 13 is pressed against the bottom plate 8 while the vinyl sheet 3 is pressed into the groove 2 of the holder with the presser plate 5, the upper and lower portions of the cuts 15 and 15 are compressed. In this state, the inwardly protruding ridges 7 and 7 are inserted into the escape recesses 14 and 14. In this state, the elastic force in the direction in which the notches 15 and 15 are opened in the vertical direction acts, so that the pressing plate 5 is always pressed against the bottom plate 8 by the lower surface 16 of the standing plate-like presser 13. Installation on the seat holder is more stable. FIG. 7 is a plan view of the state in which the standing plate-like presser 13 is mounted on the holder 1, and is mounted at substantially constant intervals. When mounting, the vertical plate-like presser 13 is inserted into the concave groove 2 and stands on the presser plate 5, and is rotated about 90 degrees in the direction of arrow a so as to be perpendicular to the longitudinal direction of the holder 1. By setting the state, the inwardly protruding ridges 7 and 7 are inserted into the escape recesses 14 and 14.

The plate thickness t of the vertical plate-shaped presser 13 in FIG. 6 is about 2 to 3 mm or slightly thicker, but the plate thickness t is further increased to form a rectangular column or square box. This is the box-shaped retainer 17 shown in FIG. The presser 17 has a solid or hollow box shape, and in the case of being hollow, the lower end and the upper end may be in an open state or in a closed state. The material may be resin or metal. And the relief recesses 14 and 14 are formed in the left and right side walls so that the inwardly protruding ridges 7 and 7 can enter. In addition, notches 15 and 15 are formed between the relief recesses 14 and 14 and the lower surface 16 as needed to increase the elasticity in the vertical direction.

In the case of being hollow, the relief recesses 14 and 14 and the cuts 15 and 15 may be in an open state, but are preferably closed. In the case of this box shape, since the plate thickness t of the vertical plate-like presser 13 of FIG. 6 is in an enlarged dimension d, the lower surface 16 becomes rectangular and becomes wider. As a result, stability when mounted in the recessed groove 2 of the holder is increased. In the case of the box-shaped presser 17 and the standing plate-like presser 13, the cuts 15 and 15 for improving the elasticity are not necessarily required if they are made of a soft synthetic resin. In the case of the box-shaped retainer 17, the elasticity can be further improved by making it hollow.

As shown in FIG. 7, the box-shaped planar shape is D × d in length and width. In order to insert into the groove 2, it is set so that “short side d <interval W between inwardly protruding ridges 7 to 7”. As a result, as in the case of the vertical plate-like presser 13, the short side d side is inserted into the opening between the left and right inwardly protruding ridges 7 and 7 and then pressed against the concave groove bottom plate 8 side 90. When it is rotated, it can be mounted like a box-shaped presser 17 shown by a broken line in FIG. In the vertical plate-shaped presser 13 and the box-shaped presser 17, the portion above the inwardly protruding ridges 7 and 7a functions as a handle for operation.

FIG. 9 is an embodiment of a plate presser that can be laid down, wherein (1) is a vertical sectional view and (2) is a side view. Reference numeral 18 denotes a protrusion, which is shaped like a screw head or a nut head, for example. A suitable size is about 3 mm in diameter. Such protrusions 18 have a shape protruding on both side surfaces of the above-described vertical plate-like presser 13 and box-type presser 17. Then, the vertical plate-like presser 13 and the box-shaped presser 17 having such protrusions 18 are inserted on the presser plate 5 and turned about 90 degrees in the direction of arrow a in FIG. In such a case, the projection 18 is provided at a position where the projection 18 sinks directly below the inwardly protruding ridges 7 and 7a. Therefore, in a state where the lower surface 16 is in contact with the pressing plate 5, it can be pushed down in the direction of the arrow a3 or a4 around the protrusion 18 as shown in FIG. As a result, the vertical plate-shaped presser 13 and the box-shaped presser 17 are in a state of being laid down into the holder concave groove 2, so that it can be prevented from protruding from the concave groove 2 and getting in the way. The vertical plate-shaped presser 13 or the box-shaped presser 17 and the protrusion 18 may be made of synthetic resin, but the metal protrusion 18 is placed in the synthetic resin-made vertical plate-shaped presser 13 or box-shaped presser 17. A mold-fixed configuration is also possible.

In the case of the V-shaped plate 10 in FIG. 4, the standing plate-shaped presser 13 in FIG. 6, and the box-shaped presser 17 in FIGS. 8 and 9, the upper side does not exist from the position of the upper one-dot chain line L <b> 1. Also good. Alternatively, the upper side from the position of the lower two-dot chain line L2 may be formed. In such a shape, since there is no handle portion, the operation becomes inconvenient, but the operation is not disabled. If an auxiliary tool is used, it can be easily operated. Moreover, since the inward protruding ridges 7 and 7a of the holder can be inserted, there is no problem in this respect. Thus, in the case of a shape having no upper side from the chain line, the expression “concave portion” is not suitable, but it functions as a relief portion that allows the inwardly protruding ridges 7 and 7 a to be fitted onto the projections 18. Therefore, the expression “escape part” is suitable.

As shown in FIG. 3 (2), when the inwardly protruding ridge 7 a is provided at the intermediate position of the side wall 9, the pressing plate 5 and vinyl are also interposed between the inwardly protruding ridge 7 a and the opening-side inwardly protruding ridge 7. If a vinyl sheet is attached in the order of the sheet, net, presser plate 5, and plate pressers 13 and 17 according to the present invention, it can also be used when two sheets of sheets, nets, etc. are stacked. Therefore, it is convenient when the seat is doubled for the north side of the house where the north wind strikes or for measures against strong winds.

The holder 1 is fixed with a fastener called a Binipet (trademark) or the like in a state where it is screwed in advance to a frame of the house or the like using a hole 18 formed in the bottom plate 8. In the state, the vinyl sheet 3 is attached and fixed as described above. When the net is also attached at the same time, it is pushed into the concave groove of the holder by the pressing plate 5 with the vinyl sheet 3 and the net overlapped. Although the vinyl sheet has been described as an example of the sheet to be attached to the house, the material may be a synthetic resin sheet and is not particularly limited to vinyl.

As described above, according to the resin sheet fixture according to the present invention, the synthetic resin sheet is pushed into the concave groove of the holder with a long strip-shaped pressing plate, and the pressing device is fitted and fixed from above. Yes. Therefore, unlike long wires made of triangular wave springs, other handling during storage is simple and safe. Furthermore, since it is small and can be manufactured inexpensively, it can be expected to spread, and an increase in horticulture and agricultural production can be expected.
