Description

  The present invention is capable of securely attaching a vertical lattice to the upper and lower trunk edges, particularly with a single touch so that the vertical grid does not come out of the upper and lower trunk edges, and is capable of being attached to the upper and lower trunk edges. The present invention relates to a fence for sloping terrain where the angle formed with the vertical grid can be arbitrarily changed within a predetermined angle range and the vertical grid does not rattle.

  For example, as shown in FIG. 13, a fence installed between a road and a sidewalk includes a column 12 attached between the column 11 and the column 11, and as the panel 12, upper and lower trunk edges 13, 14, In some cases, a plurality of vertical lattices 15 are fixed between the upper body edge 13 and the lower body edge 14 at right angles to the body edges 13 and 14.

  When such a fence is installed on a road surface without a gradient, the rectangular panel 12 can be manufactured in advance at the factory, so that the installation cost of the fence can be reduced. Since the road gradient varies, it is necessary to manufacture the panel 12 having different angles formed by the upper and lower trunk edges 13, 14 and the vertical grid 15 according to the road gradient. The installation cost increased.

  Therefore, for the purpose of reducing the installation cost of the fence, it is desired to develop a fence that can arbitrarily change the attachment angle between the upper and lower trunk edges 13 and 14 and the vertical grid 15 in accordance with the road gradient. An example of such a fence for slopes is disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2004-360372). Hereinafter, this fence is called a conventional fence and will be described with reference to the drawings.

  14A and 14B are diagrams showing a conventional fence, where FIG. 14A is a front view, FIG. 14B is a side view, and FIG. 14C is a part of part A of FIG. 14A. FIG. 15 is a view showing a vertical lattice of a conventional fence. FIG. 15 (a) is a partially omitted cross-sectional view, and FIG. 15 (b) is a CC line of FIG. FIG. 16 is a partially omitted front view showing a support member for fixing the vertical lattice to the upper trunk edge and the lower trunk edge.

  As shown in FIGS. 14 to 16, the conventional fence includes a column 16 and a panel 17 attached between the columns 16. The panel 17 is attached between the upper and lower trunk edges 18 and 19, and between the upper and lower trunk edges 18 and 19, and the end portions are formed at the upper trunk edge 18 and the lower trunk edge 19. A plurality of pipe-like vertical lattices 20 inserted into the rectangular insertion holes 18A, 19A and the vertical lattices 20 are formed on both body edges 18, 19 so that they do not escape from the upper body edge 18 and the lower body edge 19. It consists of the support material 21 to fix. Both ends of the vertical lattice 20 are narrowed in a square shape, and through holes 20A into which the support material 21 is inserted are formed in these portions. The support member 21 has a rod shape, and a bent portion 21A for preventing the support member 21 from coming off is formed at one end.

  In order to install the conventional fence constructed as described above, as shown in FIG. 14 (c), the ends of the vertical lattice 20 are inserted into the insertion holes 18A formed in the upper trunk edge 18 and the lower trunk edge 19, respectively. The support member 21 is inserted into the through-hole 20A at the end of the vertical lattice 20 protruding into the pipe-shaped body edges 18 and 19 from the ends of the body edges 18 and 19.

  In this way, by inserting the support material 21 into the through holes 20A at the ends of the vertical lattice 20, each vertical lattice 20 has both cylinders so that they do not come out of the upper trunk edge 18 and the lower trunk edge 19. The upper and lower cylinders are attached to the edges 18 and 19 and there is a slight clearance between the rectangular insertion holes 18A and 19A of the trunk edges 18 and 19 and the ends of the vertical lattice 20 and the through holes 20A. The attachment angle between the edges 18 and 19 and the vertical lattice 20 can be arbitrarily changed within a predetermined angle range. Therefore, the fence can be installed according to the road gradient.

(A) Inserting the support material 21 from one end of the trunk edges 18 and 19 and inserting it into the through holes 20A of all the vertical grids 20 includes inserting the end portions of the vertical grids 20 and the insertion holes 18A of the trunk edges 18 and 19 19A are square with each other, and although the vertical lattice 20 does not rotate around the axis, the through holes 20A are not necessarily aligned in a straight line, which is an extremely difficult operation. In particular, in the case of a small-sized fence and the vertical lattice 20 has a small diameter, the inner diameter of the through-hole 20A becomes small, which is a serious work.
(B) In order to make it possible to arbitrarily change the attachment angle between the upper and lower trunk edges 18, 19 and the vertical grid 20 within a predetermined angle range, the through holes 20A are enlarged to some extent at both ends of the vertical grid 20. Although it is necessary, if it does in this way, the vertical lattice 20 will rattle.

  Next, an embodiment of the fence for slopes according to the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a fence for slopes according to the present invention, FIG. 2 is a partially omitted plan view showing a lower trunk of the fence for slopes according to the invention, and FIG. 3 is a vertical lattice of the fence for slopes according to the invention. FIG. 4 is a cross-sectional view taken along line AA of FIG. 1, FIG. 5 is a development view showing the support material, FIG. 6 is a perspective view showing the support material, and FIG. FIG. 8 is a perspective view showing another shape of the support material, FIG. 9 is a view showing the attachment state of the trunk edge and the vertical lattice, and FIG. Front view when there is no slope on the fence installation road surface, Figure (b) is a front view when the fence installation road surface is an upward slope, and Fig. (C) is an illustration of the fence installation road surface with an upward slope. FIG. 10 is a perspective view showing a support member having another shape, and FIG. 10 (a) shows one piece of a leaf spring outward. Ri bent perspective view showing a supporting member forming a nail, Fig. (B), (c) is a perspective view showing a supporting member fixed to another pawl member into one piece of leaf spring.

  As shown in FIG. 1, the sloped fence according to the present invention includes a column 1 and a panel 2 that is fixed between the columns 1 via a bracket (not shown) so that the angle can be adjusted. The panel 2 is mounted between an upper trunk edge 3 and a lower trunk edge 4 each made of a round pipe, and between the upper trunk edge 3 and the lower trunk edge 4, and the ends are connected to the upper trunk edge 3 and the lower trunk edge 4. A plurality of vertical lattices 5 made of round pipes to be inserted, and a support member for fixing the vertical lattices 5 to the upper trunk edge 3 and the lower trunk edge 4 so that they do not come out of the upper trunk edge 3 and the lower trunk edge 4 6 (see FIG. 7).

  When the vertical grid 5 is attached to the upper trunk edge 3 and the lower trunk edge 4 at a right angle, the vertical grid 5 is in contact with the upper inner surface of the upper trunk edge 3 and the lower end of the vertical grid 5 is the lower trunk. It has a length in contact with the lower inner surface of the edge 4. The length of the vertical lattice 5 is set in this way because the vertical rattling generated in the vertical lattice 5 when the vertical lattice 5 is attached to the upper trunk edge 3 and the lower trunk edge 4 is changed to the upper and lower trunk edges 3. This is to prevent it regardless of the inclination angle of 4.

  Near the upper end of the vertical lattice 5, there is provided a claw upper opening 5 </ b> A through which a later-described claw 8 enters and exits. Near the lower end of the vertical lattice 5, a lower claw opening 5 </ b> B through which the claw 8 enters and exits is provided. It is provided on the side opposite to the upper opening 5A for use (see FIG. 3). The reason why the claw upper and lower openings 5A and 5B are thus formed on the opposite sides and the claw 8 is also provided on the opposite sides will be described later.

  As shown in FIG. 2, circular vertical lattice openings 4 </ b> A into which the ends of the vertical lattice 5 are inserted are formed in the lower trunk edge 4 at intervals equal to the intervals of the vertical lattice 5 in the axial direction. Yes. In the upper trunk edge 3, similarly to the lower trunk edge 4, circular vertical lattice openings 3 </ b> A are formed at an interval equal to the interval of the vertical lattices 5 in the axial direction.

  The diameters of the openings 3A and 4A are formed to be somewhat larger than the outer diameter of the vertical grid 5 in consideration of the inclination of the vertical grid 5, but the openings 3A and 4A are formed on the axes of the upper and lower trunk edges 3 and 4. If the openings 3A and 4A are formed to have long holes in the direction and the width of the openings 3A and 4A is equal to the outer diameter of the vertical grid 5, the vertical grid 5 can be prevented from rattling in the radial direction of the upper and lower trunk edges 3 and 4. .

  As shown in FIGS. 5 and 6, the support member 6 protrudes from the leaf spring 7 which is inserted into the vertical lattice 5 and bent into a U-shape, and the outer surface near the end of one piece of the leaf spring 7. It consists of a claw 8 provided. The claw 8 has a side surface 8A that inclines continuously inward toward the end portion of the vertical lattice 5 on the leaf spring insertion side.

  As shown in FIG. 5, the claw 8 forms a pair of overhanging portions 7 </ b> A whose width dimension increases toward the end of the leaf spring 7 on both sides in the vicinity of one end of the leaf spring 7. Each of them is formed by bending the leaf spring 7 outward at a right angle. As shown in FIG. 10A, even if a part of one piece of the leaf spring 7 is bent outward so that the front shape thereof becomes the shape of the claw 8 in FIG. good.

In this way, in addition to forming a claw 8 by bending a part of one piece of the leaf spring 7, a separately produced claw member is fixed to the leaf spring 7 as shown in FIGS. 10B and 10C. You may do it. FIG. 10C is a reference example.

The front shape of the claw 8 may be a shape in which the side surface 8A has a semicircular shape as shown in FIG. 11B , in addition to the shape in which the side surface 8A is inclined as described above. As shown in (c), the side surface 8A may have a ¼ circular shape. FIG. 11A is a reference example in which the side surface 8A has a shape parallel to one piece.

  When the end of the vertical grid 5 is inserted into the vertical grid openings 3A, 4A, the claw 8 is in contact with the vertical grid openings 3A, 4A, and resists the elastic force of the leaf spring 7 in the vertical direction. After being pushed into the lattice 5, the claw 8 is restored by the elastic force of the leaf spring 7, protrudes from the claw upper and lower openings 5 </ b> A, 5 </ b> B, and the inner surfaces of the upper and lower trunk edges 3, 4. Engage. Thereby, the vertical lattice 5 is fixed so that it does not come out of the upper and lower waist edges 3 and 4.

  The side surface 8A of the claw 8 is formed with a protruding portion 8B that engages with the outer surface of the vertical lattice 5 when the claw 8 protrudes from the upper and lower openings 5A and 5B. When a rotational force around the axis acts on the vertical lattice 5, a force is generated in the claw 8 to be pushed into the vertical lattice 5 (see FIG. 7). Depending on the magnitude of the rotational force around the axis, the vertical lattice 5 May rotate. However, with the protrusions 8B, even if a large rotational force around the axis acts on the vertical grid 5, the protrusions 8B engage with the outer surface of the vertical grid 5, so that the claws 8 are pushed into the vertical grid 5. This prevents backlash around the axis of the vertical grid 5.

12A to 12C show the front shape of the claw 8 in which the protruding portion 8B is formed on the claw 8 having the shape shown in FIGS. 11A to 11C. FIG. 11A and FIG. 12A are both reference examples.

  As shown in FIG. 8, the bent end of the leaf spring 7 may be turned upside down. In this case, the direction of insertion into the vertical lattice 5 is reversed.

  In order to assemble the fence for slopes according to the present invention configured as described above, the following is performed.

  First, the support member 6 is inserted into the upper and lower trunk edges 3 and 4 and the bent spring 7 is retracted, and the bent end is inserted into the vertical lattice 5. When the claw 8 comes to the positions of the claw upper and lower openings 5A and 5B, the claw 8 protrudes from the claw upper and lower openings 5A and 5B by the elastic force of the leaf spring 7.

  When the support member 6 is inserted into the vertical lattice 5 in this manner, the ends of the vertical lattice 5 are inserted into the vertical lattice openings 3A, 4A of the upper and lower trunk edges 3, 4. At the time of this insertion, the claw 8 is pushed into the vertical lattice 5 against the elastic force of the leaf spring 7 with its side surface 8A in contact with the longitudinal lattice openings 3A, 4A. 7 is returned by the elastic force of 7, protrudes from the upper and lower openings 3 </ b> A and 4 </ b> A, and engages with the inner surfaces of the upper and lower trunk edges 3 and 4.

  As shown in FIG. 9A, the fence for slopes according to the present invention can be easily installed on a road with a slope as well as a road with a slope according to the road slope.

  In the case of installation on a road with an upward slope, the upper and lower trunk edges 3 and 4 are inclined upward with respect to the vertical lattice 5 as shown in FIG. In this case, since the claws 8 of the support member 6 inserted in the upper and lower ends of the vertical lattice 5 are provided on the opposite sides, the angle formed by the upper and lower trunk edges 3, 4 and the vertical lattice 5 is It can be arbitrarily changed within a predetermined angle range.

  That is, when the upper and lower trunk edges 3 and 4 are inclined leftward with respect to the vertical vertical grid 5, the upper right side (P1) and lower left side (P2) of the vertical grid 5 The upper left portion (P3) and the lower right portion (P4) are separated from the inner surfaces of the upper and lower trunk edges 3 and 4 while being in contact with the inner surfaces of the edges 3 and 4. At the same time, the contact point (Q1) between the lower surface of the upper end side claw 8 of the vertical lattice 5 and the inner surface of the upper trunk edge 3 and the contact point of the upper surface of the lower end side claw 8 of the vertical lattice 5 and the inner surface of the lower trunk edge 4. (Q2) is in contact with the tip (Q3) of the upper end claw 8 of the vertical lattice 5 and the tip (Q4) of the lower end claw 8 of the vertical lattice 5 are the upper and lower trunk edges 3, 4 away from the inner surface. In this way, the upper and lower trunk edges 3, 4 can be inclined with respect to the vertical grid 5. In the opposite direction, the upper and lower trunk edges 3 and 4 cannot be inclined.

  When installing on a road with an upward slope, as shown in FIG. 5C, the front and back of the panel may be reversed from the case of FIG.

  As described above, according to the sloped fence corresponding to the present invention, the following effects are brought about.

(1) The vertical grid 5 can be attached to the upper and lower trunk edges 3 and 4 so as not to come out from both trunk edges with one touch only by inserting the vertical grid 5 into the upper and lower trunk edges 3 and 4.
(2) By making the length of the vertical lattice 5 the distance between the upper inner surface of the upper trunk edge 3 and the lower inner surface of the lower trunk edge 4, the vertical lattice 5 can be prevented from rattling in the vertical direction.
(3) By attaching the claws 8 of the support member 6 that engage with the inner surfaces of the upper and lower trunk edges 3, 4 in the reverse direction above and below the vertical grid 5, the upper and lower trunk edges 3, 4 and the vertical grid 5 Can be arbitrarily changed within a predetermined angle range.
(4) By forming the protrusions 8B on the claws 8, it is possible to prevent rattling around the axis of the vertical lattice 5.
