Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence structure which can be suitably used for constructing an outer fence of a house or a building, or a lattice of a doghouse.

[0002]

2. Description of the Related Art A fence structure installed in a general household yard, for example, a kennel, has been widely used as a box type in which a front side is a doorway of a dog and a floor is integrally formed.
Those manufactured using wooden or metal panels were the mainstream.

In place of such a conventional kennel, only a frame and a roof on its upper surface are provided around the periphery and a floor is provided so that the ventilation can be improved or the dog can lie down on the ground and lie down. The one without the method became used heavily. This type of kennel is constructed of metal rods or tubing, and the ground side and roof side piers are horizontally arranged, and a grid of bars or tubing is placed between these piers. The materials are arranged in a vertical position.

FIG. 6 is a schematic view showing a main part of a conventional connection structure between a crosspiece and a lattice member. In (a) of the figure, the crosspiece 51 used for arrangement on the ground side is a tubular material having a hollow rectangular cross section having a thickness of about 0.5 to 1 mm, and the grid material 5 is used.
Numeral 2 uses a circular metal pipe. On the upper surface of the crosspiece 51, mounting holes 51a having a circular opening for inserting the lattice member 52 are formed at a predetermined pitch.

As shown in FIG. 1B, the grid member 52 is inserted into the mounting hole 51a, and the lower end thereof is connected to the bar 5
1 and are integrally connected by bead or spot welding around the mounting hole 51a.

[0006]

As described above, in the conventional connection structure between the crosspiece and the grid material, the periphery of the mounting hole 51a is fixed by welding. There is a problem that the generation is quick and the life is short.

In the case of punching a metal plate, punching by a die punch is generally used when the thickness of the plate is small. Is performed.

However, the crosspiece 51 is a tubular material having a rectangular hollow cross section. Since the mounting hole 51a is formed only in the peripheral wall facing the upper surface side of the crosspiece 51 as shown in the example in the figure, the lower surface side is formed. It is necessary to hold the crosspiece 51 with a dedicated mold jig so that the punch does not hit the peripheral wall. This mold jig is a rod having a cross-sectional shape that can be inserted into the crosspiece 51, and is supported by the cantilever with respect to the crosspiece 51. The tool is likely to be deformed, causing damage to the mold punch and the mold jig. Further, the accuracy of the opening size of the punched mounting hole 51a is likely to vary, and a process such as a polishing operation for management and repair after the punching is added, which has a great effect on cost.

[0009] Further, in order to open ten mounting holes 51a in one crosspiece 51, it is necessary to replace the material and to perform two punching steps by using a die punch, so that there is a limit in improving the productivity. .

The problem to be solved in the present invention is to eliminate the occurrence of rust by further eliminating welding by simpler processing and to provide an inexpensive fence structure composed of crosspieces and lattice members. is there.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a plurality of columns, upper and lower bars connected to the columns, and upper and lower ends connected to the upper and lower bars. In the fence structure made of a grid material, the grid material is formed into a rectangular or circular cross section with grooves by bending a plate material.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a lattice member inserted into an opening provided in a bar is inserted from the outside of the bar into a direction perpendicular to the longitudinal direction of the lattice, such as a screw or a rivet. It can be set as the structure joined with the crosspiece by the joining material. Further, it is also possible to adopt a configuration in which a pressing piece that presses against the outer peripheral surface of the lattice member is provided inside the crosspiece.
The ends of the grooves of the columns, grid members and crosspieces may be bent inward. Further, the crosspiece can be formed in a rectangular cross section with grooves by bending and punching an opening into which the end of the lattice member is inserted into a plate material.

[0013]

1 is an external view of a dog house provided with a fence structure according to the present invention. In the figure, a doghouse is configured by arranging a plurality of pillars 1 in contact with the ground at parallel intervals, and connecting a roofing material 2 to the upper ends of these pillars 1. And
The lower beam 3 is connected between the columns 1 on the ground side,
An upper beam 4 is connected to a lower side of the roofing material 2. And
A pair of right and left columns 1 occupying the left half of the front
Further, a door 5 is attached to a portion surrounded by the upper and lower rails 3 and 4 connected to the door 5 so as to be freely opened and closed by a hinge structure.

The peripheral wall of the kennel shall cover the rear half of the left and right end surfaces and the back surface with a panel 6, and these panels 6 will be fixed to the columns 1 and the upper and lower cross members 3, 4 by screws and the like. A grid member 7 is connected to a portion occupying the right half of the front and the front halves of the left and right side faces at regular intervals with respect to the upper and lower cross members 3, 4.

FIG. 2 is an exploded perspective view of a main part showing a connection structure of the lattice member 7 to the lower beam 3. The lower cross member 3 is made of a metal plate having a thickness of, for example, about 0.5 to 1.0 mm, and is bent so as to have a cross-sectional shape that is concave below a shape whose lower surface is open as illustrated. It has been processed. A mounting opening 3a having a square opening cross section is opened in a portion of the upper end wall facing the front side edge, and a joining screw 8 is provided on a surface below the mounting opening 3a and facing the front. A screw hole 3b for passing through is provided. When fixing with rivets instead of the screws 8, holes for rivets are provided instead of the screw holes 3b. The lower ends of the lower crosspieces 3 are formed with bending margins 3c and 3d which are slightly bent inward.

On the other hand, the lattice member 7 is formed by bending a metal plate having the same thickness as that of the lower beam 3 and has a concave cross-sectional shape like the lower beam 3 and has an outer shell. The dimensions are such that they can be fitted into the mounting opening 3a. A hole 7a for screwing the screw 8 as a tapping screw or a hole for rivet is formed in a portion where the lattice member 7 faces the front, and bending margins 7b and 7c are formed by bending both sides of the back end slightly inward. I have.

The upper beam 4 also has the same structure as the lower beam 3 and has an opening for opening the grid member 7 at a position facing the lower surface so that it can be inserted and fixed. . Also, the frame member 5a and the lattice member 5b of the door 5 are assembled by the same connection structure.

Here, the lower beam 3 is manufactured by slitting a metal flat plate into a strip having a predetermined width, and attaching a required number of mounting holes 3a and screws to each of the flat strips. The hole 3b is punched by a die press and then bent to have the cross-sectional shape shown in FIG. 2 to obtain a final product. Alternatively, when a roll forming machine is used, holes can be formed at the time of cutting after molding. In the case of such forming, since the work (the lower beam 3 in the form of a strip before processing and forming) is flat, the work is positioned and fixed on a surface plate, for example, and a plurality of punching pins are formed. If a mold press is used, all the mounting openings 3a can be opened for one lower beam 3 by one press. Of course, the same applies to the screw hole 3b.

With such a method for processing the lower beam 3,
Compared with the conventional processing in which a hole is formed in a tube material as in the related art, not only the number of presses is reduced by half, but also the dimensional accuracy of the mounting port 3a is improved, so that the cost can be reduced and the product accuracy can be improved.

FIG. 3 is a longitudinal sectional view of a main part when the lattice member 7 is connected to the lower beam 3. At the time of attaching the upper and lower crosspieces to the support and attaching the lattice to the upper and lower crosspieces, the lattice material inserted from the mounting opening 3a is replaced by screws 8 passed through the screw holes 3b.
Is screwed into the hole 7a as a tapping screw, whereby the lattice member 7 can be connected to the lower beam 3. Needless to say, instead of screwing the screw 8 with a tapping screw, a female screw may be cut into the hole 7a in advance.

In such a connection structure of the lattice member 7, the front portion on the lower end side is restrained by the screw 8 with respect to the main beam 3.
It is supported by the fitting of the opening edge of a. Therefore, the grid member 7 can be connected to the lower beam 3 by a combination of the screw 8 fastening and the fitting of the mounting opening 3a, and the joining by welding as in the related art is unnecessary. For this reason, in the case of welding, rust is easily generated due to the modification of the metal material, but such rust can be suppressed to improve durability and appearance.

In the example shown in FIG. 3, the lower end of the grid member 7 is located above the bending allowance 3c of the lower beam 3, but the bending allowance 3c
Screw hole 3b and hole 7a when inserted
And a dimensional relationship that matches In this case, the grid member 7 is inserted into the mounting opening 3a, and the positioning can be performed at the time when the tip of the grid material 7 hits the bending allowance 3c and does not move, thereby further simplifying the assembling. Further, not only the connection with the lower cross member 3 but also the connection of the lattice member 7 with the upper cross member 4 is completely the same, and the connection between the frame member 5a and the lattice member 5b of the door 5 can be assembled in the same manner. .

As described above, the grid member 7 can be connected to the upper and lower cross members 3 and 4 without welding, and the door 5 is the same. Therefore, even in a dog house installed in an environment exposed to rain, rust is generated. , A good appearance can be maintained over a long period of time.

FIG. 4 shows another embodiment, in which pressing members 3e and 4e are provided on upper and lower cross members 3 and 4, respectively, and a pressing force is applied to the outer surface of the lattice member 7 by the pressing members 3e and 4e. To enable stable holding. The processing of the pressing pieces 3e and 4e can be performed at one time at the time of drilling the iron plate.

The upper and lower crosspieces 3 and 4 have substantially the same cross-sectional shape as that of the previous example, and press pieces 3e and 4e are formed on the side walls thereof in accordance with the arrangement pitch of the lattice 7. These pressing pieces 3e, 4e are cut out on three sides of a part of the side walls of the upper and lower rails 3, 4 to protrude inward, or are pressed by the lower rail 3, as shown in FIG. The lower end of the piece 3e abuts on the outer surface of the lattice member 7, and the upper end of the pressing piece 4e abuts on the outer surface of the lattice member 7 in the upper rail 4. Further, the pressing pieces 3e,
4e, the grid member 7 is also restrained by the elastic bias of the grid member 4e.
Can be stably maintained.

The grid member 7 and the support 1 are shown in FIG.
By forming the bent portions 7d and 1a by bending the ends of the grooves inward as shown in (a) and (b), danger such as injury during assembly, handling or use is prevented, and safety is ensured. Can be enhanced.

In the above embodiment, the column 1, the lower beam 3, the upper beam 4, and the lattice member 7 have a rectangular cross section, but may have a groove with a circular cross section. In the above-described embodiment, the fence structure of the doghouse is taken as an example. However, it is needless to say that the invention can be similarly applied to a fence structure such as an outer fence in which a lattice member is assembled on upper and lower crosspieces.

【The invention's effect】

(1) The struts, crosspieces and lattice members are formed by bending a plate into a rectangular cross section with grooves, and in the case of joining by conventional welding, the life is short due to the generation of rust and the like. Thus, the generation of such rust can be prevented and the durability can be greatly improved. Also, the appearance is not impaired for a long time. Further, since there is no need for processing such as seam welding, surface finishing of a welded portion, and zinc spraying when manufacturing a pipe, costs can be significantly reduced.

(2) The grid member inserted into the opening of the crosspiece is connected to the crosspiece by a joining material such as a screw or a rivet which is inserted from the outside of the crosspiece in a direction orthogonal to the longitudinal direction of the grid material. Can be assembled only by inserting the lattice member into the opening and screwing in the screws or driving in rivets.

(3) Since the number of screws can be greatly reduced in the case where the pressing piece is provided, the screw cost can be saved.
The number of assembling steps is reduced, and the assembling can be performed easily.

(4) By bending the ends of the grooves of the pillars, the grid members and the crosspieces inwardly, it is possible to prevent the danger of cutting hands during assembly, handling, and use, thereby improving safety. .
