Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for fixing a band, and particularly to a band fixing device for tensioning a single band by partially varying the tension. The purpose is to provide a band fixing device that allows easy adjustment of the tension of the band and allows easy attachment and detachment of the device.

As this type of band fixing device, the applicant has
Already filed Utility Application No. 54-154581 (Utility Application No. 51-71154)
However, the present invention is an attempt to further improve the invention related to the above-mentioned application. That is, as shown in the first diagram, generally, in a greenhouse 1, there are a plurality of support frames 2, 2, etc. installed and fixed in parallel at appropriate intervals, and a plurality of support frames 2, 2... are installed in the depth direction of the greenhouse so as to be perpendicular to these frames. It is framed by the beam frames 3, 3, and large and small heat-retaining vinyl sheets 4a, 4b are stretched from the outside thereof, and the edge of the large sheet 4a among the overlapping closed edges of the two sheets is The sheet 4a is opened and closed by fixing a take-up rod 7 to and rotating it forward and backward.

The entire sheet 4a is pulled by this winding operation, and the sheet 4a is
Fix the open proximal end of a, and in order to prevent the covering sheets 4a, 4b from being agitated and damaged by strong winds, etc., apply dusty bands 6', 6', etc. made of vinyl etc. from the outside of the sheets at appropriate intervals. I'm passing it on carefully.

Thus, when the winding rod 7 is in the overlapping position of the sheets 4a and 4b during the opening/closing operation of the sheet 4a, the tightening band 6' tightly fixes the sheet 4a on the sheet fixing member 5. With,
The winding rod 7 is pressed against the support frames 2, 2, . . . . Next, when the winding rod 7 is rotated by the handle 7a and the sheet 4a is rolled up and released, the diameter of the sheet wound around the rod gradually increases according to the number of rotations.
It rolls while pushing up the band 6', and as the amount of winding increases, the frictional resistance between the support frame 2 and the band 6' increases. When winding rotational force is applied against this frictional force,
The torque is determined by the seat fixing member 5 of the seat 4a.
This acts as a strong tensile force on the sheet opening/closing portion 41a between the winding rod 7 and the winding rod 7. For this reason, it is inevitable that the seat 4a will be damaged frequently at the fixing portion of the seat fixing member 5 that fixes the seat 4a.

In order to eliminate this drawback, it is necessary to prevent the sheet fixing portion from being affected by the clamping frictional resistance caused by the band during sheet winding and unwinding operations. For this reason, it is necessary to tension the fixed tension side of the sheet for each band 6' with the fastening member 5 as a boundary, and at the same time to relax the side of the sheet portion 41a where opening and closing operations are performed.

The present invention has the same purpose as the above-mentioned application in order to eliminate the above-mentioned drawbacks, but it is an object of the present invention to provide a band fixing device that is more complete and convenient for attachment, detachment, and adjustment.

That is, the present invention has a detachable base 12 on the crosspiece member 10, and has a band insertion groove whose longitudinal section orthogonal to the band insertion direction is approximately square-shaped, and whose bottom is an inclined surface 13a for band pressure contact. The fixture body 11 has a groove frame body 13 having a groove frame 13, and has an inclined surface 20 for band pressure contact corresponding to the inclined surface 13a of the fixture body 11.
It consists of a wedge-shaped insertion member 19 formed so as to be able to be freely fitted into the band insertion groove.

Hereinafter, the present invention will be described in detail based on embodiment figures.
FIG. 2 shows the device of the present invention installed in a greenhouse, and FIG. 3 is an enlarged cross-sectional view taken along the line A--A in FIG. 2. In FIG. 2, the same reference numerals, such as the members constituting the greenhouse and the sheet winding device, represent the same members as in FIG. 1. In the figure, reference numeral 10 denotes a cross-section member having a substantially rectangular cross section, with rising pieces 10a on both side edges,
10a is provided, and furthermore, this rising piece 10
Ribs 10b, 10b are provided at the tips of a, 10a to protrude inward. This crosspiece member 10 is attached on the support frame 2 in parallel with the beam frame 3. The fourth figure is an exploded perspective view of the band fixing device according to the present invention, and in the figure, reference numeral 11 denotes a fixing device body made of a material such as plastic. Thus, the fixture main body 11 has a base 12 that can be detachably fixed to the inside of the crosspiece member 10 at the lower part thereof, and has an inclined surface 13a that serves as a band pressure contact surface at the upper part. A groove frame 13 having a substantially square shape is formed. The base 12
In the example, the bottom surface is approximately rectangular, and
The length of the short side is made slightly shorter than the distance between the ribs 10, 10, and the length of the long side is made shorter than the distance between the ribs 10, 10.
It is formed to be slightly longer than the distance between 0b and 10b, and arcuate chamfered portions are provided at a pair of diagonal corners. For this reason, after inserting the long side of the base 12 parallel to the ribs between the ribs 10b, 10b, the base 12
The fixture main body 11 is fitted and fixed to the crosspiece member 10 by simply rotating the fixture body 11 by 90 degrees in the direction of the arrow 18 shown in the fourth figure. 14 is a groove formed between the base 12 and the fixture main body 11. The sheet 4a is stretched and fixed along the inner surface of the crosspiece member 10 via a metal spring 15 made of wire or piano wire, a base 12, and a groove 14, as shown in the third figure. Reference numerals 16 and 16 designate stoppers that protrude inwardly from the upper inward ribs 13b and 13b of the groove frame 13, and are in the form of elastic protrusions. 6 is a sheet tensioning band made of a material such as vinyl. Reference numeral 19 denotes a substantially wedge-shaped insertion member, the bottom surface of which has an inclined surface 20 for press-contacting the band 6 in correspondence with the groove bottom inclined surface 13a of the fixture main body 11. Further, the upper surface portion thereof has a protrusion 21 for insertion and removal operation. As shown in FIG.
An abutment surface 23 is provided which is abutted against and latched to the stopper 16, and a tapered portion 24 for guiding the passage of the stopper 16 is provided at the upper rear end thereof. Reference numeral 25 denotes a rack-shaped surface formed on the inclined surface 20 of the insert member, and may be provided as required.

The sixth figure shows another embodiment of the fixing device main body 11, and includes an inclined surface 13a at the bottom of the groove.
are formed on the rack-shaped surface 26.

The one shown in FIG. 7 is another embodiment of the insert member 19, in which the guide taper portion 2 at the lower rear end of the projection 21
4 is formed so as to slightly protrude from the stopper contact surface 23. In addition, in this case, the stopper contact surface 23 is at least
It is formed to have a height that allows the tip of 6 to come into contact with it.

The eighth figure shows still another embodiment of the fixture body, etc., in which the groove bottom 13a of the fixture body 11 is formed in a channel-shaped surface 27, and the lower surface of the insertion member 19 corresponds to this. is also formed on a convex surface 28 corresponding to the channel-like surface 27. Thus, the insert member 19 is attached to the band 6.
When the band 6 is inserted, it is pushed upward by the thickness of the band 6 and becomes locked. That is, in the embodiment shown in FIG.
The tips 22, 22 of the stoppers 16, 16 come into contact with the contact surfaces 2, 22, 22, 22, 22 of the stoppers 16, 16, as shown in FIG.
3 is provided as a concave portion inwardly from the guide taper portion 24, the tips 22 of the stoppers 16, 16,
22 enters below the tapered portion 24 and comes into contact with the contact surface 23. Therefore, the insert member 19 will not come off from the fixture body while the band 6 is being inserted.

Also, if band 6 is not inserted,
The insert member 19 is lowered by the thickness of the band 6 than in the above case. Therefore, Figures 5 and 7
In the illustrated embodiment, the abutment surface 23 includes the stopper 16,
16, and the guide taper portion 24 faces the tips of the stoppers 16, 16. Then, when the insert member 19 is moved in the direction of the arrow n in this state, the stoppers 16, 16 are pushed apart by the guide taper 24, and the insert member 1 is easily moved.
9 can be extracted from the fixture body 13.

Since the stoppers 16, 16 are elastic and the distance between their ends is smaller than the thickness of the insert member 19, they will not naturally fall off from the main body 13 unless the above-mentioned sliding removal operation is performed.

Next, the case where the band fixing device according to the present invention is actually installed in a greenhouse will be explained. First, as shown in the second figure, in a greenhouse 1 consisting of a support frame 2, a beam frame 3, vinyl sheets 4a, 4b, a crosspiece 10, a winding rod 7, a handle 7a, etc., the band 6 is attached to the beam frame 3. Hang it in a direction perpendicular to the greenhouse, and tie both ends to the lower end of the side wall of the greenhouse, or fix it near it with stakes, etc. At this time, the band is fixed by leaving enough slack in advance so that the band does not apply frictional resistance to the winding and unwinding of the winding rod 7.

Next, as shown in FIG. 9, the base 12 of the fixture main body 11 is attached to the desired position on the crosspiece member 10 by simply rotating it by 90 degrees as described above. Furthermore, band 6
is loosely inserted into the groove frame 13 of the fixture main body 11. Thereafter, with the insert member 19 placed on the upper surface of the band 6, the insert member 19 is pressed and inserted into the groove frame 13 in the direction of arrow m. FIG. 10 is a perspective view showing a state in which the band 6 has been inserted and inserted as described above. When the band 6 is pulled in the direction of the arrow n in this state, a force is applied in the direction of the wedge-shaped insertion member 19 coming out, so that the pressing force with the groove bottom 13a is weakened, and the band 6 slides smoothly and is pulled. At this time, the insert member 19 moves slightly in the direction of coming out, but there are projections 2 on the tips of the stoppers 16, 16.
Since the lower end contact surface 23 of 1 collides with each other, it does not escape.
After obtaining the desired tightening force on the band on the normally closed side of the seat, when the tension on the band is stopped, the band 6
tries to return to the normally closed side. However, since there is frictional resistance between the groove bottom 13a that is being clamped and the insert member 19, the insert member 19 is moved along with it in the pushing direction. Here, since the insertion member 19 is wedge-shaped, there is almost no accompanying movement, and this force acts as a clamping force to fix the band. Therefore, band fixation can be completed by simply stopping the tension in the n direction. FIG. 11 is a longitudinal cross-sectional view of the above-mentioned fixed state, and as a result of fixing the band 6 as described above, the band 6 on the seed closing side is maintained in a tensioned state with the fixing device main body 11 as a boundary, and The front band 6 on the open side of the seat is maintained with a predetermined degree of relaxation.

When adjusting the tension of the band 6, leave the insertion member 19 attached and return it slightly in the opposite direction of the arrow m, loosen the clamping pressure, and pull the band in the n direction to obtain the desired band tension. At this point, the insert member 19 may be pressed and inserted again in the direction of arrow m to be fixed.

The present invention has the above-mentioned structure, and the fixing device body and the insertion member act organically, so that the band on the closing side is kept in tension with the fixing device body as a boundary, and the band on the opening side is maintained in the desired state. The tension of the band can be adjusted accurately with simple operations to maintain the band's relaxation. Therefore, in addition to being able to smoothly roll up and unwind the vinyl sheet while the greenhouse band remains in place,
Since no unreasonable tension is applied to the sheet at the fastening points, damage to the sheet can be sufficiently prevented. Furthermore, since the fixture main body can be detachably attached to a desired position on the crosspiece member, the work of fixing the band can be easily performed. Furthermore, if the band is configured to be crimped with the tapered surface of the fixing device body and the insert member, the clamping frictional force applied to the band will be large, and a reduction in the tightening force due to slipping can be prevented. . In addition, the guide piece of the fixing device body and the contact surface of the pressing member act to prevent the band pressure contact area from loosening, so that the tension of the band is maintained for a long period of time, making it easy to wind up and unwind the sheet. It is. Therefore, it has many excellent features such as being able to provide the most effective greenhouse.

Although the embodiment of the present invention is shown for the case where it is implemented in a greenhouse, it is not limited to this, and furthermore, two crosspiece members are provided in parallel on the left and right or top and bottom, and the fixture body is It is also possible to adjust the tension and relaxation of the bands when they are configured to face each other.
