BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to connecting vertical objects such as a vertical frame and a horizontal frame of a fence in an intersecting manner, or connecting a tree or the like in a cross manner from a desired direction with a support pillar for reinforcement. TECHNICAL FIELD The present invention relates to a tightening fixture suitable for use in cases such as occasions.

[0002]

2. Description of the Related Art Generally, a fence installed in a park, a passage, or the like intersects a vertical frame, which is erected at a predetermined interval on the ground, with a suitable number of horizontal frames intersecting each other. Tightening and fixing work is performed by tying means such as binding the portion with a wire or a string. Further, as a conventional fastening and fixing means for connecting the vertical frame and the horizontal frame without using the above-mentioned tying means, a band ring-shaped band having an adjusting screw for adjusting a tightening amount rotatably, Tightening fixture with a structure in which two bodies, one that is inserted into the vertical frame side and the other that is inserted into the horizontal frame side, are prepared, and the two parts are symmetrically contacted and the midway portions are connected by bolts so that the angle can be adjusted. It has been known.

[0003]

However, the conventional means for binding the intersection of the vertical frame and the horizontal frame with a wire or the like is to freely wind the wire according to the shape and thickness of the vertical and horizontal frames. Although there is an advantage that it can be tightened by tightening, there is a tendency for the tightening state to vary due to differences in the skill of workers,
There is a defect that the end of the wire cut with pliers after being twisted and knotted is exposed, impairing the landscape and lacking safety.
On the other hand, the latter tightening fixture is one in which a vertical frame and a horizontal frame are individually inserted into the rings of the two bands that are connected, and then the adjustment screw is tightened by a tool such as a screwdriver to fix the band. Therefore, there is an advantage that it is possible to reduce variation in tightening for each worker and impair the appearance of tightening, but it is complicated to insert the vertical frame and the horizontal frame into the rings of the two bands. Since it is necessary to tighten and adjust the adjusting screws in two places, the tightening and fixing work becomes inefficient, and the structure of the tightening and fixing tool is complicated and the cost is high. In addition, when supporting a tree or the like, there is a problem that it is difficult to flexibly respond to the wind and support it.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described with reference to the drawings. 1 to 5, reference numeral 1 denotes a tightening fixture according to the present invention. This tightening fixture 1 has a loop-shaped outer circumference of an outer rod-shaped body (outer rod-shaped body) 2 which serves as a vertical frame in the figure. A pair of bands 3 and 3a surrounded by and a rod-shaped body (inner rod-shaped body) 2a which is in contact with each other and which is an inner horizontal frame are included in the outer periphery, and both ends of the pair of bands 3 and 3a are located at the proximal side. The pair of bands 3 and 3a are arranged so that their loop portions are close to each other and are engaged so as to be in a cross shape in a front view as shown in FIG. By using the configuration having the engaging portion 31 to be engaged, it is possible to appropriately clamp and fix a plurality of rod-shaped bodies as objects to be clamped such as piles, pipes or trees in a state of being in contact with each other in a cross shape. It is possible to support fences and trees in parks efficiently and satisfactorily.

The detailed structure of each part of the tightening fixture 1 will be described below. The tightening adjusting part 5 includes an upper adjusting band 6 to which one (upper) band 3 of the pair of bands can be attached. And a holder part fixed to the inner adjusting band 6a by surrounding the both with the adjusting band 6a to which the other (lower) band 3a can be attached and the adjusting bands 6 and 6a being placed on the outside and inside. 7, and a head 90 on the holder portion 7.
And an adjusting screw 9 that rotatably inserts a screw portion 91 in a state where the upper part of the adjusting band 9 is held upward to support the adjusting screw 9, and the adjusting screw 9 is formed in a plurality of recesses on the outer periphery of the adjusting band 6 with a screw pitch interval. It is configured to be meshed with the thread groove 60 so as to be screwed.

The adjusting bands 6 and 6a in the illustrated example are formed by bending inwardly a flat strip made of steel material to form an inner rod-shaped body 2a.
And the inner side of the adjustment band 6, 6a wider than the width of the adjustment band 6, 6a is formed in the plate-shaped mounting piece 61,
The bases on the respective mounting sides of the bands 3 and 3a that surround the outer rod-shaped body 2 in a loop shape on both sides of the mounting piece 61 are attached with a tightening interval L in a stable manner. That is, mounting piece 6
Reference numeral 1 denotes a mounting hole 62 into which each end of a band 3 or 3a formed by forming a wire material into a loop can be inserted. The mounting hole 62 is wider on both sides than the width of the adjusting band 6 or 6a and the outer rod 2 The adjustment bands 6 and 6 are formed so as to have a tightening and holding interval H that is close to the diameter of the adjustment holes.
It is connected to a.

As a result, the adjusting screw 9 is rotated in the tightening direction, and the mounting pieces 61, 61 of the adjusting bands 6, 6a are rotated.
When the two are brought close to each other, both ends of the bands 3 and 3a can be pulled as linearly as possible through the attachment pieces 61 and 61, and it is unreasonable even for the outer rod 2 having a large diameter. Instead, it has advantages such as efficient tightening.

It should be noted that the mounting piece 61 is composed of the adjustment bands 6, 6a.
Or by press punching, etc.
It may be attached by an appropriate joining means such as welding or screwing. Further, the mounting piece 61 in the illustrated example includes adjustment bands 6, 6
It is attached in a fixed state by inserting a screw (mounting pin) 8 into a. However, if the screw 8 is loosened if necessary, the mounting piece 61 is rotatable about the screw 8. , The bands 3 and 3a can be flexibly supported in a swingable manner, and the inner rod 2a and the outer rod 2 are misaligned, or the outer rod 2 has an indefinite shape. In this case, there is an advantage that the mounting piece 61 can freely rotate in response to this, and the fastening and fixing of the both can be performed well and satisfactorily.

The bands 3 and 3a are attached by inserting the ends into the mounting holes 62 of the mounting pieces 61 and bending them. At this time, as shown in FIGS. The bending portion 30 is formed by bending toward the free end side of the band 3, 3a, and the bending portion 30 is extended from the end of the mounting piece 61 and joined to the body base side of the band 3, 3a. . As a result, in the use state in which the tightening fixture 1 tightens and connects the outer rod-shaped body 2 and the inner rod-shaped body 2a, the adjustment bands 6, 6 are adjusted by the adjustment screw 9.
When a is pulled, the bending portion 30 is strongly pressed by the inner rod-shaped body 2a and joined and supported on the bands 3 and 3a side. Therefore, even when the tightening fixture 1 is strongly tightened, the bending portion 30 However, there is an advantage in that the tightening fixture 1 having sufficient strength can be provided with a simple structure since it does not return and deform.

The pair of bands 3 in the illustrated example
When attaching both ends to the attachment piece 61, 3a is attached in a state in which the loop portions are crossed inward and outward so as to overlap each other, so that the fastening fixture 1 of FIG. In addition, an engaging portion 31 is formed such that both loop portions are close to each other in a cross-sectional view when viewed from the front. According to this configuration, the outer rods 2 are trees vegetated on the ground, and the inner rods 2
In the case where a is a fence frame that supports the middle part of the trunk of the tree, the bands 3, 3a have a tightening interval L from the attachment pieces 61, 61 whose base side is joined to the fence frame side in a side view. Then, at approximately the height of the central portion of the tightening interval L, the tree is surrounded while gradually converging toward the engagement portion 31 located on the free end side thereof, and the engagement portion 31 is seen from the front view. The trees are supported by the fence frame in a stable manner at a cross-point one-point contact supporting state at the substantially central part.

Therefore, when the tree is shaken by the wind and the trunk is bent, the bands 3 and 3a are converged from the fence frame side toward the engaging portion 31 side, as shown by the dotted line in FIG. Compared to a tree in which the free ends of the loop portions of the bands 3 and 3a are supported by a suitable means such as a spacing member 3b so as to have a width substantially equal to the tightening interval L, the band 3 , 3a are converged to the free end side as shown by the solid line, so that they can be flexed freely without significantly hindering the flexion of the trunk, and an unreasonable load is applied to trees and fences,
Proper support of trees can be achieved without causing significant damage to the trees. Further, since the tightening fixture 1 supports so that the bending of the tree can be freely released in the one-point contact support state, the bands 3 and 3a have strong winds like the above-mentioned other type of tightening fixture. There is a feature that the bands 3 and 3a can favorably prevent the displacement of the tightening and fixing position, and the deformation and damage of the tightening fixture 1 itself without directly receiving a large bending load.

As shown in the illustrated example, the engaging portion 31 is attached to the mounting piece 61 so that the loop portions of the pair of bands 3 and 3a are engaged with each other in such a manner that the loop portions intersect inside and outside. For example, when the upper part of the tree bends and tilts toward one side, the upper band 3 tries to follow in the same direction,
At this time, the lower band 3a cross-engaging the band 3
However, since the band 3 is pulled so as to prevent its movement, the band 3 can be favorably returned to its original proper supporting position without moving largely. Further, as in the illustrated example, by engaging the loop portions of the bands 3 and 3a in a crossed manner, the engaging portion 31
The tightening fixture 1 provided with is advantageous in that the structure of the engaging portion 31 is simple and inexpensive, and the assembling and manufacturing thereof can be made extremely simple.

Incidentally, the engaging means of the engaging portion 31 is not limited to the above-mentioned one, and for example, with the band 3 and the middle portion of the band 3a crossed, the mounting pieces 61, which are opposed to each other at their band ends, are provided. You may attach to 61 alternately.
Further, in a state where the loop portions of the bands 3 and 3a are vertically close to each other, they may be engaged and coupled by an appropriate coupling tool. When using the tightening fixture 1, when it is desired to protect and support the surface of a tree or the like, an appropriate cushioning member such as cloth is interposed between the bands 3 and 3a and the tree (the outer rod 2). You should wear it.

Next, with reference to FIGS. 2 to 5, an example of usage of the tightening fixture 1 will be described. Each of the outer rod-shaped body 2 and the inner rod-shaped body 2a in the illustrated example is a column formed of wood into a cylindrical column having a substantially constant size, and both columns are continuously longitudinally and laterally through the tightening fixture 1. By tightening and fixing them in combination, a series of fences suitable for parks can be installed efficiently and firmly, and at the same time, the safety can be improved while providing a beautiful appearance without spoiling the scenery It is something that can be done.

That is, when installing the above-mentioned fence, first, in a state in which a plurality of outer rods 2 are erected on the ground with a predetermined column interval, the fastening fixture 1 is attached to the outer rods 2. Bands 3 and 3a are inserted from above to temporarily hold the inner rod 2a at the mounting position, and then between the outer rod 2 and the tightening adjusting portion 5 of the tightening fixture 1 in the temporarily held state. After the inner rod-shaped body 2a is inserted from the side into the space formed by 1 and positioned at a predetermined joining position, the adjusting screw 9 is rotated in the tightening direction. Incidentally, the temporary holding of the tightening fixture 1 may be performed by making the outer rod-shaped body 2 in the vertical direction and the inner rod-shaped body 2a in the lateral direction, which is the opposite of the illustrated example, and the outer rod-shaped body 2 is used as necessary. It is preferable to select the side and the side of the inner rod 2a.

By tightening and turning the adjusting screw 9,
The adjustment band 6 screwed to the adjustment screw 9 contracts, and the mounting pieces 61, 61 relatively come close to each other, so that the bands 3 and 3a are pulled together and become tense, and tightened with the bands 3 and 3a. The outer rod-shaped body 2 and the inner rod-shaped body 2 are connected to the adjusting portion 5 side.
It is possible to pull a together and firmly bond them to each other, and it is possible to efficiently and easily fasten and fix both.

At this time, the adjusting screw 9 of the tightening adjusting portion 5 is
Since the head 90 is directed upward, the head 90
Satisfactorily prevents rainwater and dust from entering the holder 7,
Rust and the like of the screw portion 91 can be prevented well, and the work of tightening and releasing the adjusting screw 9 can be easily and easily performed by using a tightening tool such as an electric screwdriver. . Further, by rotating the adjusting screw 9 in the tightening direction, the adjusting band 6 engaged with the adjusting screw 9 is provided.
Moves so as to be drawn into the holder portion 7, so that the end portion of the adjustment band 6 is located below without protruding upward, and the wire end portions of the bands 3 and 3a are bent inside the attachment piece 61. As a result, it is possible to prevent the physical contact with these and not to impair the scenery.

The tightening fixture 1 of the illustrated example is made of a metal member, but it may be made of a plastic material, and the bands 3 and 3a are made of a plastic band or a fiber rope. In addition to the above, the tightening adjustment section 5 is not limited to the illustrated example. That is, the tightening adjustment section 5 may be a fixing tool that releasably connects both ends of the band like a conventional patchon lock. It is preferable that a locking operation side for releasably locking the hook portion is provided at each end of the pair of bands 3 and 3a, and the bands 3 and 3a themselves are formed of a relatively strong elastic member. .

In the tightening fixture 1 in this case, the end portions of the pair of bands 3 and 3a are unlocked from the tightening adjusting portion 5 to easily open these portions. Therefore, for example, when the rod-shaped body is to be vertically mounted on the inner rod-shaped body 2a framed in the horizontal direction, the tightening adjustment part 5 is mounted with the fastening fixture 1 mounted on the inner rod-shaped body 2a. With respect to the opened bands 3 and 3a, the rod-shaped body can be easily and easily inserted into the bands 3 and 3a loosened through the opening portions, and the tightening adjustment portion 5 can be easily locked. The rod-shaped body can be promptly attached and fixed by an operation, and the rod-shaped body can be easily removed by an operation reverse to the above. Therefore, the tightening fixture 1 configured as described above is preferably used as a fixture for mounting a temporary sticking member such as a warning light, a diffuser lamp, or a rod-shaped tacking member such as a flag. It is also possible.

[0022]

As described above, the present invention has the following effects. A pair of bands surrounding the outer circumference of the outer rod, and a tightening adjustment part for adjusting both ends of the pair of bands on the outer side of the inner rod while separately attaching the both ends. By using a tightening fixture that engages the loop portions of the pair of bands in a cross shape, it is possible to easily and stably support the inner rod-shaped body and the outer rod-shaped body in a crossed state. At the same time, it is possible to favorably support the bending of trees and the like.

Further, by engaging the loop portions of the pair of bands in a state where they intersect with each other inward and outward, the engaging portions can be easily manufactured at low cost.

Further, the tightening adjusting portion is composed of an adjusting band that rotatably supports the adjusting screw and an adjusting band that is slidably abutted on the adjusting band and screwed with the adjusting screw. By forming a mounting piece with a tightening clamping gap wider than the adjustment band at the end of the, and using the tightening fixture with both ends of each band separately attached to the mounting piece, The tightening and adjustment of the pair of bands can be easily performed at the same time by a dynamic operation, and at the end of the adjusting band, a mounting piece having a wide clamping gap is formed. Since they are separately attached, there is an advantage that the tightening can be satisfactorily performed smoothly even on an object to be fastened having a large diameter.
