Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet fixing device for fixing a translucent sheet to a frame of a greenhouse in a greenhouse.

[0001]

2. Description of the Related Art A fixing device for a sheet in a greenhouse of this type comprises a long supporting frame having a narrow opening and an elastic locking line fitted in the supporting frame. It is common to fix a vinyl sheet by pressing it with a line.

On the other hand, when a thin soft film having a thickness of about 0.1 mm is used as a sheet for a greenhouse, as a fixing device for a sheet which is good for fixing the sheet, for example, Japanese Utility Model Publication No. 54-42992, registered as a utility model. No. 2094
A technology as disclosed in Japanese Patent Application No. 628 has been developed.

[0003] The sheet fixing apparatus disclosed in the above publication has a long supporting frame having a narrow opening portion, and a separable presser which is fitted in the long supporting frame and clamps the sheet with the long supporting frame. Frame, and a pressing member that fits into the holding frame and presses the holding frame against the inner wall of the long supporting frame, and the holding frame has a straight perforated line or a longitudinal direction at the center of the bottom along the longitudinal direction. A notch meandering along is formed.

According to the fixing device for each sheet described above, the sheet is fitted into the long supporting frame via the pressing frame, and the pressing frame is pressed to both sides by the pressing members. The sheet is clamped in cooperation with the long support frame while being divided into two parts, so that wrinkling of the sheet can be prevented.Or, since the pressing member does not directly hit the sheet by the holding frame, the sheet is pressed by the pressing member. Can prevent damage,
Alternatively, breakage due to rubbing of the sheet can be prevented.

[0005]

However, the sheet fixing apparatus disclosed in Japanese Utility Model Publication No. Sho 54-42992, in which a perforated line is formed, cannot be reused once it has been cut off by the perforated line, resulting in poor economy. . Moreover, when trying to push the sheet into the long support frame with the holding frame, the tension of the sheet, in other words, the self-restoring force of the sheet trying to return to the horizontal state, acts on the back of the holding frame,
In some cases, the presser frame may be bent inward around the perforation line, or may be bent in the opposite direction around the perforation line.In order to perform sheet fixing work while suppressing such movement, Workability is inferior.

Further, in order to divide the holding frame through the sewing machine wire, a pressing member having a strong spring force or a strong pressing force is required, and the workability is significantly reduced, and the workability of the part becomes difficult. Therefore, when a holding frame made of a material that can easily cut the sewing line, for example, a thin plastic holding frame, is formed, the holding frame is deformed partly or entirely by losing the pressing force of the pressing member, and wrinkles are formed on the sheet. In addition to the above, the holding frame is easily deteriorated and has poor durability.

On the other hand, Japanese Utility Model Registration No. 2094628 using a holding frame having a meandering cut in the center.
According to the sheet fixing device disclosed in Japanese Patent Application Laid-Open Publication No. H10-209, the problem of bending and curling of the holding frame is slightly solved, but the operation of reusing when replacing the sheet is extremely troublesome. That is, when the pressing member is pressed by the pressing member during fixing of the sheet, the pressing frame is divided into two right and left parts and separates. For this reason, when replacing a sheet, take out the two divided holding frames independently from the inside of the long support frame, insert a new sheet again, and try to clamp the sheet with the holding frame. The holding frame must be fitted into the long supporting frame while aligning the cut surfaces. At this time, the tension from the sheet acts on the back of each holding frame. The fitting operation has to be performed while positioning the holding frame, and the work of mounting the holding frame is extremely troublesome, which causes a reduction in work efficiency.

Further, Japanese Utility Model Registration No. 2094628 discloses a technique for expanding the bottom of the holding frame in an expander manner by making a plurality of cuts.
According to this method, if the diameter is once expanded in the lateral direction by the pressing member, it may not be possible to return to the original position due to the self-restoring force, and the lateral width may be kept expanded. For this reason, if the sheet is reused at the time of replacing the sheet, it is troublesome to take it out of the long support frame, and when it is fitted into the long support frame again, the mounting work becomes troublesome due to the large width. Furthermore, even in various conventional techniques using the holding frame as described above, for example, when fixing a hard synthetic resin sheet or a sheet made of a mesh net, the sheet is slippery, so that the sheet is strong due to wind or the like. When an external force acts, the slide frame may slip out of the holding frame and the long support frame and come out.

Therefore, an object of the present invention is to not only prevent the generation and breakage of wrinkles of the sheet, but also to use a pressing member having a weak pressing force, and to reuse the sheet repeatedly when replacing the sheet. An object of the present invention is to provide a sheet fixing device in a greenhouse which can significantly improve the work and prevent the sheet from slipping out.

[0010]

In order to achieve the above object, one aspect of the present invention is to provide an elongated support frame having a narrow opening having a horizontal bottom and both side walls rising from both ends of the bottom. And a press frame fitted in the long support frame and holding the sheet with the long support frame; and a press fitting in the press frame and pressing the press frame against the inner wall side of the long support frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 3 show an embodiment of the present invention.

The fixing device for a sheet includes a long supporting frame 1 having a narrow opening and a holding frame 3 fitted in the long supporting frame 1 and holding the synthetic resin sheet 2 with the long supporting frame 1. And a pressing member 6 composed of a locking line 4 or a locking plate piece that fits into the holding frame 3 and presses the holding frame 3 against the inner wall of the long supporting frame 1. As the pressing member 6, the locking wire 4 and the locking plate piece may be used independently or independently and simultaneously. As the sheet, a synthetic resin sheet or a sheet made of a mesh net is used.

The long support frame 1 is provided with a dovetail-shaped groove as in the prior art, and is provided with a horizontal bottom 1a, a pair of side walls 1b, 1b standing upright from both ends of the bottom 1a, and a curl 1c at the upper end. It consists of a frame with a dovetail-shaped cross section. Similarly, the holding frame 3 is formed in a similar shape to the long supporting frame 1 and also has a dovetail-shaped groove.
The sheet 2 is uniformly sandwiched between the inner wall of the sheet and the outer surface of the holding frame 9, thereby preventing the sheet 2 from being wrinkled or broken.

The holding frame 3 includes a pair of left and right locking frames 7, 7 slidably disposed in the horizontal direction, a bottom frame 8 connected to the base end of one locking frame 7, and a second locking frame 7. And a plate-shaped bottom frame 10 continuously connected to the base end of the base plate. The angle of the pair of left and right locking frames 7, 7 is formed to be the same or substantially the same as the angle of both side walls 1b, 1b in the long support frame 1, and curls 11, 11 as curved pieces are continuously provided above them. ing.

The bottom frames 8, 10 connected to the respective locking frames 7, 7 are inclined downward at an arbitrary angle and are integrally connected, whereby the locking frames 7, 7 and the bottom frames 8,
10, the angle θ2 of the dovetail-shaped groove 12 formed is larger than the angle θ1 of the dovetail-shaped groove 13 on the long support frame side.

A guide groove 9 is formed in one bottom frame 8 along the longitudinal direction. Usually, the other bottom frame 10 is inserted into this guide groove 9 so as to be slidable in the horizontal direction. The holding frame 3 has a bottom frame 10 on one locking frame 7 side inserted into the guide groove 9 so that the width between the two side locking frames 1b, 1b is equal to that of the bottom 1a of the long supporting frame 1. The width is made smaller than the width, and in this state, the transport, storage, or attachment / detachment operation into the long support frame 1 is performed.

That is, when fixing the sheet 2, first, the sheet 2 is pushed into the long supporting frame 1 via the holding frame 3. The holding frame 3 is fitted obliquely from the opening of the long support frame 1 in a state where the locking frames 7 are compressed. In this state, for example, the locking line 4 is
When the locking wire 4 is forcibly fitted against the self-elasticity, the locking wire 4 presses the locking frames 7, 7 in the left-right direction, whereby the locking frames 7, 7 and the bottom frame 8, 10 is slid horizontally while being guided by the guide groove 9, and the respective locking frames 7, 7 are pressed against the inner wall of the long supporting frame 1, and as a result, the sheet 2 is supported by the locking frames 7, 7 and the long supporting frame. The frame 1 is sandwiched between the side walls 1b, 1b so that it does not come off.

On the other hand, when the sheet 2 is to be replaced, the locking lines are removed and the locking frames 7, 7 are pushed inward with a finger or the like.
The holding frame 3 can be taken out from the long supporting frame 1 in a state in which the width is reduced by sliding inward along the line.

Here, it should be noted that when the locking frames 7, 7 are pushed right and left by the locking filaments 4, the other bottom frame extends to near the exit end of the guide groove 9 as shown in FIG. 10 moves, and the locking frames 7, 7 abut on both walls 1b, 1b.
The two bottom frames 8, 10 at are inclined downward. For this reason, the two bottom frames 8 and 10 are substantially V-shaped, and even if a load is applied to the seat 2 by an external force such as wind and rain, the pressing frame 3 itself is prevented from bending upward from the center.

Similarly, from the seat 2 to the locking frames 7, 7 and the bottom frames 10, 10, arrows X,
Even if a force is applied to compress the entire holding frame 3 in the X direction, the force in the compression direction presses each of the locking frames 7, 7 obliquely inward, and the bottom frames 8, 10 become sharper. The angle becomes a V-shape. As a result, FIG. 3 (B)
As shown in FIG. 5, the upper surface of the other end of the bottom frame 10 is caught by the outer end edge A of the guide groove 9, and the lower end edge B of the bottom frame 10 is also caught by the lower surface of the guide groove 9 at an acute angle. Due to the hooking action of B, the other bottom frame 10 is kept in a state of being invaded into the guide groove 9. In other words, when the holding frame 3 is slid in the lateral direction, the sheet 2 is uniformly held in cooperation with the long supporting frame 1, and the holding frame 3 is not compressed even when an external force acts on the sheet 2, and the sheet 2 is not compressed. Can be maintained. Further, the bottom frames 8 and 10 are formed in a V-shape and stretched, so that an effect of forming a rigid structure in which the long support frame 1 and the V-shaped pressing frame 3 are united is also produced.

Is expanded in a reverse V-shape, and the same operation and effect as described above can be obtained.

Next, FIGS. 19A and 19B to FIG.
(A) and (B) show an embodiment of a mechanism for preventing a sheet from slipping.

As described above, since the holding frame 3 is fitted into the long supporting frame 1 and the inner surface of the long supporting frame 1 and the outer surface of the holding frame 3 hold the sheet 2, the sheet 2 is held. Even if an external force acts on the seat 2,
Has the effect that it cannot be removed by external force such as ordinary wind. However, when the sheet 2 is formed of a hard material having a smooth surface, such as a hard synthetic resin, or a sheet made of a synthetic resin net,
Becomes easy to slide with respect to the long support frame 1 and the holding frame 3. For this reason, when a large external force such as a typhoon acts on the sheet 2, the sheet 2 vibrates when it flaps in the vertical direction, and a force is exerted on the sheet 2 to escape from the long support frame 1 in the horizontal direction. 2 slips out. For this reason, there is a possibility that the skeleton fixing the seat 2 is distorted, or a ventilation device provided at an end of the seat 2 is opened.

The seat slip preventing mechanism shown in FIGS. 19 to 24 is designed to cope with the above-mentioned problem.

FIG. 19A shows a sheet fixing mechanism 50 added to the outer surface of a sheet holding frame 3 used in the sheet fixing device shown in FIGS. That is,
A number of sawtooth-shaped grooves 5 formed along the longitudinal direction on the outer surface of the intersection between the locking frame 7 and the bottom frames 8 and 10.
1 is provided with a non-slip mechanism 50. Instead of the sawtooth-shaped groove 51, a number of irregularities may be used.

FIG. 19B also shows another anti-slip mechanism 50 having the same saw-tooth groove 52 on the outer surface of the intersection between the locking frame 7 and the curl 11 in addition to the above.
Is provided.

In this case, when the holding frame 3 is fitted into the long supporting frame 1, the sheet 2 is moved to the long supporting frame 1.
The sheet 2 is hooked on the non-slip mechanism 51.

For this reason, even if an external force due to a large typhoon or the like acts on the sheet 2, the anti-slip mechanism 51 applies a large friction to the sheet 2, so that the sheet 2 becomes less slippery and consequently becomes longer. The horizontal support frame 1 is prevented from coming off in the horizontal direction. It is preferable that the non-slip mechanism 51 is provided at a position where the clamping force with respect to the sheet 2 is the largest, but it may be formed over the entire outer surface of the holding frame 3.

FIG. 20 shows another embodiment in which a non-slip mechanism 50 is provided, which is formed as a rough surface 52 in which the outer surface of the intersection between the locking frame 7 and the bottom frames 8 and 10 is rough. The rough surface 52 imparts friction to the sheet 2.

FIG. 21 shows another embodiment of the non-slip mechanism 50, in which a concave groove 53 is formed on the outer surface of the same intersection as described above, and fitted into the concave groove 53 along the longitudinal direction. It is made of rubber 54 adhered or adhered. In this case, the rubber 54 imparts friction to the sheet 2.

FIG. 22 also shows another embodiment, in which a non-slip mechanism 50 is formed by paint or particles 55 wiped at the same intersection as described above.

FIG. 23 relates to another embodiment, in which a saw-toothed groove 56 or a non-slip mechanism 50 composed of irregularities is formed on the inner surface of the dovetail-shaped groove 13 of the long support frame 1. . Also in this case, the anti-slip mechanism 50 applies friction to the sheet 2.

The non-slip mechanism 50 may be provided on the entire inner surface of the long support frame 1, as in the above embodiment.
Rough, rough, wiped paint or numerous particles,
Rubber or the like fitted or attached may be used.

FIG. 24 relates to another embodiment of the present invention, which is a modification of the holding frame 3 in the same sheet fixing device as that of FIG. 1, which strengthens the clamping force and prevents the sheet from slipping. Things.

That is, as shown in FIG. 12A, the curls 11 are formed by extending the upper ends of the pair of left and right locking frames 7 constituting the holding frame 3 upwardly from the side walls 1b of the long supporting frame 1, respectively. A plate-like projection 56 for urging the sheet 2 downward is provided at the end of the curl 11 so that the projection 56 is used as a sheet urging force urging member. In this case, it is preferable that the lower end of the projection 56 protrudes below the top of the curl 1c of the long support frame 1.

By using the projection 56, when the sheet 2 is extended, the projection 56 presses the sheet 2 downward from the top of the curl 1c, and tension is applied to the sheet 2. As a result, the sheet 2 is further tensioned. Moreover, when an external force such as wind acts on the sheet 2, the sheet 2 is pulled in the horizontal direction as shown by the arrow X, and at this time, the sheet 2 pushes the projection 56 upward as shown by the arrow Y.
For this reason, the locking frame 7 rotates around the curl 1c of the long support frame 1 via the curl 11, and the locking frame 7 is urged in the direction of further tightening the sheet 2 as indicated by the arrow Z, so that the sheet 2 To prevent the seat 2 from slipping.

FIGS. 24 (B) and 24 (C) show that the upper end of the curl 11 is bent or substantially horizontal, and a circular projection 56 is formed on this end.
a, 56b are deformed, and the sheet 2 is urged downward by the projections 56a, 56b. Fig. 12
This is the same as the case (A).

[0064]

According to the present invention, the following effects can be obtained.

(1) According to the first to sixth aspects of the present invention, since the bottom frames are slidably inserted through the guide grooves, the locking frame can be compressed in the compression direction and expanded in diameter through the guide grooves. Direction, and can be compressed and compacted normally, making transport and storage easy. When in use, the pressing members slide the frames on both sides in the transverse direction, which is the diameter expansion direction, so that the sheet is sandwiched between the locking frames and the long support frame to prevent the sheet from sagging and wrinkling, and to prevent the sheet from rubbing. Prevent breakage.

(2) According to the first to sixth aspects of the present invention, since the bottom frames are fitted to each other or the support plate is present at the center, the bottom frame or the support plate reinforces the entire holding frame, Even if the tension from the sheet acts in the compression direction, the frames on both sides are prevented from bending or warping, so that the attachment / detachment operation to the long support frame of the holding frame is significantly improved, and thus the sheet fixing work is improved. In addition, the work efficiency can be improved and the work cost can be reduced.

(3) Similarly, according to the first to sixth aspects of the present invention, since the locking frame is at the same angle as the both sides and the bottom frame is inclined upward or downward, the holding frame is expanded in diameter from side to side. When the sheet receives a force in the compression direction from the sheet, it tends to form a sharper V-shape, whereby the end edge of the bottom frame is caught and movement in the compression direction is prevented, and Can maintain the clamping. Further, when the holding frame is V-shaped, a rigid structure is formed by the long supporting frame and the sheet fixing device itself becomes a rigid frame of the greenhouse.

(4) According to the sixth aspect of the present invention, since the anti-slip mechanism or the hooking mechanism is provided, it is possible to prevent the pressing frame from being more strongly compressed.

(5) According to the seventh, eighth, and ninth aspects of the present invention, since the sheet non-slip mechanism is provided, even if a large external force such as a typhoon acts on the sheet, the mechanism applies friction to the sheet, and Can be prevented from slipping through.
