Description

[Detailed explanation of the invention] [Industrial application field] This invention is used to divide partitioned areas such as pastures, farms, and outdoor breeding grounds where livestock are allowed to roam, and to prevent livestock from going outside. This relates to the structure of the pasture fence.

[Prior Art] As shown in Fig. 9, most of the conventional fencing for this type of pasture are made by planting wooden posts a at predetermined intervals, and fixing them by nailing wooden crossbars b to them. Because these pasture fences are exposed to the wind and rain, they corrode or crack, resulting in low durability and the disadvantage of requiring frequent repairs. So the 10th
As shown in the figure, a pasture fence in which top rail e, middle rail f, and bottom rail g are fixed to straight metal posts c via brackets d has been considered, but grazing grounds are generally left with the natural topography as it is. To accommodate the sloped terrain, we prepare brackets of various shapes and select and use the one that matches the slope of the terrain.

[Problem to be solved by the invention] As mentioned above, preparing many types of brackets and selectively using them on site is extremely inefficient and uneconomical.
This resulted in the construction of pasture fences that did not necessarily match the slope of the terrain, resulting in an unfavorable appearance. Moreover, in the conventional structure, the posts are straight, so there is a risk that livestock, especially horses, may come into contact with the fence and the posts or the protruding heads of screws or bolts may injure the horse's body.

[Means for Solving the Problems] In order to solve the problems that should be solved with the conventional structure mentioned above, this invention is based on a pillar whose upper end is biased towards the inside of a partitioned area such as a grazing field. A top rail bracket is bolted in advance to a substantially horizontal circular opening at the upper end of the support, and a fixing body having a shape that fits into the opening is inserted and fixed, A middle rail bracket and a bottom rail bracket are attached to the inner middle and lower portions of the pillars via bolts that pass through the pillars and are screwed into female threads of abutting parts protruding from these brackets, Each of the brackets is formed with a tapered through hole that opens at both ends and gradually widens toward the center, and a top rail, a middle rail, and a bottom rail are inserted into the through holes of each bracket from both sides, The present invention provides a pasture fence in which the ends of each rail are fixed by fasteners such as bolts that thread through these brackets.

[Function] In the above configuration, one type (one set) of fixing bodies is prepared as a top rail bracket, a middle rail bracket, and/or a bottom rail bracket, and each rail is supported and fixed according to the topography, and the pasture fence is installed. Configure.

[Example] This invention will be described in detail below with reference to the drawings.

First, Figures 1 and 2 are a side view and a sectional view schematically showing how the pasture fence of this invention is assembled, and 1 shows a shape in which the upper end is biased towards the inside of a partitioned area such as a grazing field. 2 is a bracket for the top rail, 3 is a bracket for the middle rail, 4 is a bracket for the bottom rail,
5, 6, and 7 indicate the top rail, middle rail, and bottom rail, respectively.

Next, the detailed structure will be explained with reference to FIGS. 3 to 6.

A top rail bracket 2 is inserted into the horizontal opening 8 at the upper end of the support 1 at a desired angle (this is determined according to the slope of the terrain).
A fixed body 1 fixed with bolts 9 and nuts 10 to
1 and secure with screws 12 from the side. And the through hole 2 of the top rail bracket 2
Insert the top rails 5, 5 from both sides of A, and fix them to the top rail bracket 2 with screws 13 from below and outside with respect to the pasture fence. Note that the fixed body 1
1 is provided with a concave portion 14 into which the head 9a of the bolt 9 is inserted, which is continuous with the bolt hole, to facilitate the tightening operation with the nut 10.

In addition, in the middle part of the pillar 1, the bolt 15 passing through the pillar 1 is attached to the middle rail bracket 3.
The middle rail bracket 3 is attached to the support column 1 by screwing into the female thread 17 formed in the abutment part 16 protruding from the middle rail 6, 6. are inserted from both sides and fixed to the middle rail bracket 3 with screws 18 from the bottom and outside of the fence, respectively.

The structure of the bottom rail 7 attached to the lower side of the middle rail 6 is the same as the mounting structure of the middle rail 6, so in FIGS. 5 and 6,
The reference numerals assigned to each part of the middle rail section are arranged, and the reference numerals of each part of the bottom rail 7 are shown for the sake of explanation. That is, an abutment part 20 protruding from the bottom rail bracket 4 to be fixed by a bolt 19 passing through the support column 1 is formed with a female thread part 21 into which the bolt 19 is screwed. are inserted from both ends of the through hole 4A of the bottom rail bracket 4 and fixed with screws 22.

What is particularly noteworthy about the above structure is that all the screws and bolts that connect each member are screwed in from the bottom or outside of the fence, and care is taken to prevent the screws and bolt heads from being exposed to the inside of the fence. It is that you are.

By using the fixing body 11 that changes the attachment angle to the top rail bracket 2 according to the slope of the terrain when each support 1 is erected as described above, the middle rail bracket 3 and the bottom rail can also be fixed. By freely changing the angle at which the bracket 4 is attached to the support post 1, the fence can be constructed in accordance with the topography.

It is necessary that the upper end opening 8 of the support column 1 and the fixed body 11 each have a circular cross section, but the through holes of each bracket 2, 3, 4 and each rail 5, 6, 7
It is sufficient that the fittings are similar in shape to each other, and therefore, in addition to circular shapes, any shapes having a square, rectangular, hexagonal, or octagonal cross section can be used.

Furthermore, the through holes 2 of each of the brackets 2, 3, 4
A, 3A, and 4A are tapered to gently widen from openings at both ends toward the center. This taper allows easy insertion even if the insertion angle of each rail varies, such as on a slope.

In the above example, the upper edge of the column 1 is connected to the fixed body 1
However, as shown in FIG. It is also possible to have a fixed body 11 positioned between the two.

As shown in FIG. 8, an example is provided in which a recess 14' into which the head of the bolt is inserted is provided on the side of the top rail bracket 2. In this case, the direction of insertion of the bolt is opposite to that of each of the above-mentioned examples.

[Effects of the invention] The above-described structure of this invention provides the following effects.

By preparing one type of top rail bracket, middle rail bracket, and bottom rail bracket, and changing the mounting angle of these brackets to the pillars, each rail can be supported and fixed accurately, easily, and securely according to the terrain, and the number of parts is It is possible to reduce the

Each rail can be easily and quickly installed on site by inserting the rail into the bracket and securing it with screws.

Since many types of brackets and rails are not required, processing costs, logistics costs, and construction costs for parts can be reduced.

By employing posts whose upper ends are biased toward the inside of a partitioned area such as a pasture field, a pasture fence can be made safe for livestock such as cows and horses.
