Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a rope mooring fitting that is used by being fixed to a pole.

Prior art and its problems Net facilities for windproofing, snowproofing, sandproofing, etc. are made by attaching nets to poles fixed at the points where they are needed. , the ropes, reinforcing or tensioning ropes, wires, etc. that make up each side of the net (in the following description and in the scope of the utility model registration request, these are collectively referred to as "ropes") are securely and firmly attached to the poles. must be worn.

FIG. 6 is a perspective view of a conventional metal fitting for securing a rope to such a pole. In this thing, the central part of one belt-shaped hardware made by cutting and raising the rope's engagement protrusions 1e and 1f is ringed to form the main body part 1b, and the both end parts 1a and 1c are in contact with each other. Bolt 2 to bolt hole 1d
This is a metal fitting 1 which is inserted through the metal fitting 1 and fastened with a nut 3 via a washer 4.

In order to attach this to the pole P, the main body portion 1b, which is a ring band, must be expanded, fitted onto the pole P, the ring must be contracted, and the ring must be tightened with bolts and nuts as described above.
The rope to be attached is sandwiched between the protrusions 1e, 1f and the main body 1b, and then fixed by hammering these protrusions from the surface side.

The problem with conventional products is that after the annular main body part 1b is expanded to fit onto the pole, it is returned to the annular shape when fastened with bolts and nuts, which tends to cause cracks in the main body part 1b and deteriorate its mechanical strength. It is easy for this to occur. Furthermore, since the main body of the fitting is in the form of a split ring, it takes up a large amount of space when being transported and stored. , it is clear that the overall size is quite large.

Therefore, the inventor of the present invention aimed to create a product that can be easily attached to a pole without causing strength deterioration like the conventional product, and can be packed up much more compactly than the conventional product when transported and stored.
The conventional split annular body is modified into a type that can be disassembled into two halves, such as a pair of semi-annular bodies that have mutually engaged and removable engagement parts on one end side, and the semi-annular body can be disassembled into two parts at the other end. I came up with the idea of tightening and restraining the body with a wedge on the side, and did a lot of research on how to realize this.
In the process, I encountered the following problem.

In order to tighten and restrain the end of the predetermined side of the semi-annular body with a wedge, it is necessary to use not only the wedge but also a locking member with a wedge hole for driving the wedge. In order to facilitate manufacturing and reduce costs, it is desirable that this locking member be as thin as possible within a range that can withstand driving of a wedge. However, if the locking member with a wedge hole is thin, the wedge is likely to wobble during driving, especially at the beginning of driving.
In addition, at this time, the metal fitting bodies are a pair of separable semi-annular bodies that are movably engaged at the engaging portion on the end side, and the pair of semi-annular bodies are not yet fixedly connected to each other. It tends to shift and move, making driving the wedge even more unstable. This made the work of driving the wedge difficult, and in order to realize the above-mentioned idea with purpose, solving the problem of wedge wobbling became a new issue.

The object of the present invention is to provide a rope fastening fitting that can be applied with a wedge fastening member that is as thin as possible without such problems, and that can embody the above-mentioned idea in a purposeful manner. It is an object.

Means for Solving the Problems The object of the present invention is to provide a first half in which an engaging portion is provided on one end side, a fixing plate portion is extended on the other end side, and a rope anchoring protrusion is formed. An annular main body part and an engaging part movably engaged with and detachable from the engaging part of the first main body part in order to form an annular main body together with the first main body part on one end side. , a second semi-annular belt-shaped main body part having a fixing plate part corresponding to the fixing plate part of the first main body part extended on the other end side and having a rope anchoring protrusion formed therein; a wedge-hole-equipped wedge part that protrudes from a fixing plate part of the main body part and is inserted into an insertion hole provided in the fixing plate part of the other body part; and the wedge-stop part inserted into the insertion hole. a wedge piece driven into the wedge hole; and a rib formed on the outer surface of the fixing plate portion with the insertion hole, one of which extends parallel to the wedge piece driving direction and guides the wedge piece between them. This is achieved by means of a rope fastening metal fitting.

It is preferable that the rope anchoring protrusions are provided on the semi-annular belt-shaped main body part so as to be arranged at approximately 90° intervals around the annular main body when the annular main body is formed by the two semi-annular main body parts. It is preferable that the rope anchoring protrusions are provided in pairs, with each pair of protrusions being cut in opposite directions. In this way, the rope hooked to the pair of protrusions is difficult to come off, and the work of securing the rope becomes easier.

Function: The metal fitting of the present invention engages the engaging portions of both half-ring belt-shaped main body parts with each other to form a ring-shaped main body with the two main body parts, and fits this into a desired position of the pole, and one of the fixed plate The wedge piece protruding from the part can be fixed to the pole by passing it through the insertion hole of the other fixing plate part and driving the wedge piece into the wedge hole of the wedge part protruding outside the insertion hole. When driving a wedge piece into this wedge hole, even if the thickness of the wedge stopper part is thin, a pair of ribs formed on the outer surface of the fixing plate part with the insertion hole and extending in parallel in the direction of driving the wedge piece is formed. , which is advantageous because it guides the wedge piece.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 5.

The illustrated metal fittings include a pair of semicircular main body parts 10 and 20 made of band-shaped metal plates, and a T-shaped wedge stopper part 30 that can be easily manufactured by sheet metal processing.
and a wedge piece 34.

The semi-annular shape of both main body parts is a half-split state in which both parts abut against the outer peripheral surface of the pole in an engaged state,
When the cross-sectional shape of the pole is circular, it is a semicircle, and when the cross-sectional shape is polygonal, the shape corresponds to half the outer circumference of the pole.

The main body parts 10 and 20 have an engaging part formed on one end side, a fixing plate part extending integrally on the other end side, and a pair of rope anchoring protrusions cut and raised in opposite directions. The structure is the same in that it is a half ring band shaped metal fitting.

One end-side engaging portion 11 of one main body part 10 includes:
Engagement beaks 15a and 15b are cut out at the upper and lower ends thereof, and a back plate part 14 is attached at right angles to the tip of the fixed plate part 13 extending to the other end side 12. Formed by bending. Engagement part 11 and other end side 1
A pair of rope anchoring protrusions 16a and 16b with opposite cutting and raising directions are provided at the intermediate portion between the anchor plate 13 and the anchor plate 13. An insertion hole 18 is provided for insertion, and protrusions 17a and 17b are provided for fixing the fixing plate portion 31 of the wedge stopper component.

As shown in the figure, the above-mentioned locking protrusions 16a and 16b are cut and raised in opposite directions as a pair, one cut and raised to open the upper side, and the other cut and raised to open the lower side. It means "cut up". The number of pairs to be cut up will be discussed later.

The back plate portion 14 is provided as necessary in the sense that it is a plate portion for providing an anchoring protrusion 19 as shown in FIG. 3 when the back surface also requires a rope attachment. be. Although only one locking protrusion is shown in this figure, it is better to use a pair of protrusions as described above.

The above-mentioned wedge stopper component 30 has a locking plate portion 32.
is passed through the insertion hole 18 of the fixing plate part 13, and the protrusion 17 is inserted with the fixing plate part 31 in contact with the fixing plate part 13.
a, 17b are sufficiently bent onto the fixing plate part 31, thereby being fixed to the fixing plate part 13.

One end of the other main body part 20 is an engaging portion 21 having engaging holes 25a, 25b that removably engage with the engaging beaks 15a, 15b of the one main body part 10, and the other end thereof The fixing plate part 23 extending to the side 22 has an insertion hole 28 for a wedge-fastening component locking plate part 32 extending from the fixing plate part 13 on one side.
is provided.

On the surface opposite to the fixing plate part 13, that is, on the outer surface, there are ribs 2 in the vertical direction that serve to guide the driving of the wedge piece 34 and to perform this stably.
9a and 29b are provided. This main body part 2
0, there are two pairs of rope anchoring protrusions [26a, 26a,
26b, 27a, 27b] are provided.

In order to fix the metal fittings made up of the above-mentioned parts to the pole P, the wedging part 30 is fixed in advance to the fixing plate part 13 of one main body part as described above, and the engaging beak 15a of one main part is fixed. , 15b are engaged with the engagement holes 25a, 25b of the other main body part.
Since this engagement is between the engagement beak and the engagement hole,
Both main body parts 10, 20 are movable to some extent in the direction of opening or closing the annular body they form, and both fixing plate parts 13a, 13b can be opened laterally in the figure.

In this opened state, both the engaged main body parts are attached to the outer periphery of the pole P at a predetermined position, and then the locking plate part 32 of the wedge stopper part 30 is inserted through the insertion hole 28 of the other fixed plate part. , Hammer the wedge piece 34 from above into the wedge hole 33 provided in the wedge stopper part. A front perspective view of the completed installation is shown in FIG. 2, and a rear perspective view is shown in FIG. 3.

During driving with a hammer, the wedge piece 34 is guided between the pair of ribs 29a and 29b extending in parallel in a predetermined direction, so even if the locking plate 32 is thin, it will not wobble at the beginning of driving. After that, the wedge piece 34 can be driven in without special care, and since the wedge piece 34 is prevented from moving after the driving is completed, it will not fall off.

When the attachment of the metal fittings to the pole P is completed as described above, hook the rope w that requires attachment to the pair of protrusions 16a and 16b as shown in FIG.
Adjust the sliding as appropriate to correct the tension and position of the rope, and once this is fixed, use a hammer to drive the protrusion into the hole created by cutting and raising the rope, and the rope will be attached here. Complete. The rope can be similarly attached to other anchoring protrusions.

In the sliding movement necessary for the above-mentioned rope anchorage, the anchoring protrusion is cut upward and downward in opposite directions.
There is little risk that the rope will come off the protrusion until the rope is tied, and the workability of the rope will be greatly improved. In addition, once the anchoring is completed, the rope attaches to the pair of anchoring protrusions, forming an S-shape in the horizontal direction in the figure, and
Since it is hammered into the hole created by cutting and raising and is secured, there is no risk of displacement.

Since the metal fittings are a combination of movable engagement between the two main body parts 10 and 20, the mechanical strength is not reduced as in conventional products.

In the embodiment described above, the rope anchoring protrusions are arranged at four locations 16, 1 at approximately 90° intervals in the orthogonal diametrical direction of the annular main body part as shown in FIG.
However, when using the main body part 10 in which the back plate part 14 is omitted, there are three positions 16, 27, and 26 in the orthogonal radial r direction. Providing at least three locations in the orthogonal radial directions as described above is preferable for rope tensioning work because the application of the rope anchoring protrusions can be selected depending on the situation at the rope tensioning construction site.

In the above description of the embodiments, the terms "one" and "the other" are used for convenience of explanation, and the words "one" and "the other" are used for convenience of explanation, and the engagement beak, the engagement hole, or the back plate part 14 and the fixing protrusion 17 in the fixing plate part are referred to as "one" and "the other". It is obvious that the elements can be interchanged from one to the other and from the other to the other, and the invention is not limited to the illustrated embodiment.

The metal fittings of this invention can be used in various situations where it is necessary to attach a rope to a pole, such as wind protection,
When setting up rope facilities for snow prevention, sand control, etc., rope anchorage when supporting tree branches in Japanese orchards, rope support for grapes, cucumbers, and other vines in gardening, and scaffolding pipes at construction sites. This is a case of assembly, etc., and the advantages of the metal fitting of the present invention are exhibited in these cases.

Effects of the invention As described above, according to the present invention, even if the thickness of the locking plate part that is a wedge stopper part is thin, it is possible to stably drive the wedge piece into the wedge hole from the beginning. It is possible to use the thinnest possible wedge fastening parts without wobbling, so that the ideas described above can be implemented in a purposeful manner.
