DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grid mounting structure for mounting a grid constituting a main component such as a gate, a fence, and a surface grid by welding to a body edge.

[0002]

2. Description of the Related Art Conventionally, in a grid mounting structure of this type, for example, in a gate made of aluminum material, a gap between an upper body edge and a lower body edge arranged vertically in parallel with a gap is provided.
A plurality of grids formed in a substantially plate shape are attached.
Each of the lattices is disposed with the front and rear extending in the expected direction, and the upper and lower ends in the longitudinal direction are welded to the upper and lower trunk edges, respectively. In such a gate, in the alumite surface treatment (anodized film treatment) in the manufacturing process, a gap between the lattice and the upper and lower body edges is avoided in order to avoid a surface treatment defect caused by air accumulation at a joint portion between the lattice and the upper and lower body edges. Is formed with a gap. That is, only one end of the grid in the expected direction is welded to the upper and lower body edges, and a gap is formed to allow air to escape from the welded portion to the other end of the grid in the expected direction (for example, Japanese Patent Application 8-
200280).

[0003]

In such a conventional grid mounting structure, the grid is welded to the upper and lower rims only at one end in the expected direction, and is supported in a so-called cantilever state. In addition, the strength of attaching the grid to the upper and lower waist edges is low. For this reason, if the grid receives an external force, it may bend around the welded portion, or if it receives a larger external force, it may come off the upper and lower body edges.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and does not hinder surface treatment or the like when a grid is welded and attached to a rim.
An object of the present invention is to provide a grid mounting structure that can be firmly mounted.

[0005]

According to a first aspect of the present invention, there is provided a grid mounting structure extending between a first body edge and a second body edge arranged in parallel with a gap therebetween in the front-back direction. In the grid mounting structure for mounting the existing substantially plate-shaped grid, a welding piece for welding the grid and an engaging piece for engaging with the grid are provided on the mutually opposed surfaces of the first body edge and the second body edge, respectively. The grid is welded to the two welding pieces at one end in the prospective direction, and the pair of engaging pieces that prevent movement in the finding direction at a pair of engaging parts separated from the one end in the prospective direction. Is engaged.

According to this configuration, one end of the grid in the expected direction is welded to the two welding pieces, and the pair of engaging portions are engaged with the engaging pieces so as to prevent swinging in the finding direction. , A grid is attached to the first and second waist edges. This allows the grid to be supported at two points, one end in the expected direction and the engagement portion, so that the grid can be firmly attached to both trunk edges. In this case, since only one end of the grid in the finding direction is welded to the both rims, the grid extends from the joined portion between the grid and the two rims, that is, from the welded one end to the other end in the prospective direction. A gap can be formed between the end in the finding direction of the body and both body edges. For this reason, when the grid is welded to both fuselage edges and then applied to the alumite surface treatment or dough coating, air can escape through the gap between the joints, effectively saving air. Can be prevented.

[0007] In this case, it is preferable that each of the engagement pieces is formed with an engagement notch for engaging the lattice by inserting the engagement portion.

According to this configuration, if the engaging portion of the lattice is inserted into the engagement notch formed in the engagement piece, the lattice can be reliably prevented from swinging in the finding direction. In addition, by adopting such an insertion form, the lattice can be engaged with the engagement piece without processing the lattice.

It is preferable that at least one of the welded portion of the welding piece and the welded portion of the lattice is formed with a weld notch which engages with the other and prevents the lattice from swaying in the finding direction.

According to this configuration, when the grid is welded to the welded pieces on both body edges, one end of the grid in the expected direction is supported by the welded piece via the weld notch. It can be held in a temporary assembled state before welding with respect to the body edge. Therefore, the grid can be welded to both body edges without using a jig for holding the grid in a temporarily assembled state. In addition, since the grid is prevented from swinging in the finding direction via the weld notch in addition to the welding, the grid can be more firmly attached to the welded pieces on both body edges even after welding.

[0011] Furthermore, it is preferable that a pair of engaging portions are further provided with defining portions for engaging with the engaging pieces and defining the arrangement position of the body edge, respectively.

According to this configuration, since the defining portion formed on the engaging portion engages with the engaging piece of the body edge to define the arrangement position of the body edge, it is incorporated in both body edges. The grid makes it possible to regulate the mutual position of the two waist edges. That is,
At the time of assembling and after assembling, both the rim and the lattice are combined with each other, so that the assembling becomes easier as a whole and the strength can be increased.

According to a fifth aspect of the present invention, there is provided a lattice-mounting structure, comprising a substantially plate-like shape extending in the front-rear direction between a first body edge and a second body edge which are vertically arranged in parallel with a gap. In the grid mounting structure for mounting the grid, welding pieces for welding the grid are provided on the lower surface of the first body edge and the upper surface of the second body edge, respectively, and the second body edge is vertically connected to the upper surface. A surface is formed, and the lattice is constituted by a plate-like lattice main body, and a rib piece provided at one end of the lattice main body in the prospective direction at right angles to the lattice main body, and the lattice main body is in the prospective direction. The other end portion is welded to both the welding pieces, and the rib pieces are in contact with the vertical surface of the second body edge.

According to this structure, the other end of the grid body in the expected direction is welded to the welding pieces of the first and second body edges, and the rib provided on one end of the grid body in the expected direction. Since the piece is in contact with the vertical surface of the second waist edge, even in the case where the grid receives an external force in the finding direction, the rib piece can effectively prevent the grating body from bending in the finding direction. That is, when the grid receives an external force in the find direction, the grid body tries to bend in the find direction around the welded portion, but the rib pieces receive a reaction force from the vertical surface of the second waist edge and are in contact with each other. Will be held. Accordingly, one end of the lattice body does not move in the finding direction, and the lattice body is prevented from bending in the finding direction.
In addition, since the vertical surface of the second body edge to which the rib piece contacts is formed so as to extend downward from the upper surface of the second body edge, the upper part of the second body edge has a structure in which dust, rainwater, and the like hardly accumulate. can do.

By providing the rib pieces 26 as described above at 0, when the door body 3 is viewed from the front, each vertical lattice 10 can be made to look thick, and the lattice portion of the door body 3 has a solid feeling as a whole. It is assumed.

The vertical grid 10 constructed as described above
Are the upper and lower engaging pieces 21,
23, the upper rear end and the lower rear end of the lattice body 25 are welded to the upper and lower welding pieces 20 and 22 as described above. In this case, the vertical lattice 10 is in a state in which the upper end of the lattice main body 25 is slightly lowered from the lower surface 8a of the upper body edge 8 and the lower end of the lattice main body 25 is slightly raised from the upper surface 9a of the lower body edge 9. ,

That is, as shown in FIG. 2, gaps 27, 27 are provided between the upper end of the lattice main body 25 and the lower surface 8 a of the upper trunk edge 8, and between the lower end of the lattice main body 25 and the upper surface 9 a of the lower trunk edge 9, respectively. 28 are formed.

On the other hand, the horizontal lattice 11 is made of a wire having a circular vertical cross section, the diameter thereof is larger than the thickness of the lattice main body 25, and is substantially the same as the width of the ribs 26 of the vertical lattice 10 in the finding direction. Is formed. The horizontal lattice 11 is welded to the rear end portion of the lattice main body 25 in a state where it is cut into the rear end, whereby the strength of the vertical lattice 10 in the finding direction is further reinforced. Also, as described above, the horizontal lattice 1

Here, a method of welding the vertical grid 10, the upper and lower body edges 8, 9 and the horizontal grid 11 will be described. When welding the vertical lattice 10 and the upper and lower rims 8 and 9, first, the upper and lower rims 8 and 9 are separated from each other by a certain distance, and the inside of the premises of the upper and lower rims 8 and 9 is set down. They are arranged parallel to each other. Next, a jig (not shown) for inserting the lattice main body 25 of the vertical lattice 10 from above into the upper and lower engaging pieces 21 and 23 via the engagement notches 21b and 23b and holding the vertical lattice 10 in a welding position. Insert it into the notch. As a result, the vertical lattice 10 is held with the lattice main body 25 in a vertical posture and perpendicular to the upper and lower body edges 8 and 9. Also, in this case, the rear end of the lattice main body 25 and the welding bent portions 20b and 22b of the upper and lower welding pieces 20 and 22 contact each other in a state of being orthogonal to each other. Then, these contacted parts are sandwiched between a pair of electrodes from above and below, that is, from the vertical lattice 10 side and the upper and lower welding pieces 20 and 22 side, and pressurized while energizing. Thereby, the rear end of the lattice main body 25 is welded in a state where it is cut into the welding bent portions 20b and 22b, and the vertical lattice 10 can be firmly welded to the upper and lower body edges 8 and 9 (the welded portion 20c). , 22c).

When the vertical lattice 10 is welded to the upper and lower rims 8, 9, the welding bent portions 20 of the upper and lower welding pieces 20, 22 are used.
b, 22b and the portion where the lattice main body 25 of the vertical lattice abuts,
The notch may be formed in advance. In this case, the vertical lattice 10 can be easily positioned with respect to the upper and lower body edges 8 and 9, and these can be held in a state where they are temporarily assembled to each other before welding. Thereby, the vertical lattice 10
Can be performed without using the jig for holding the welding in the welding position. Also, the upper and lower welding pieces 20, 22
When notches are formed in both the grid body 25 and
Not only positioning in the horizontal direction but also positioning in the vertical direction can be easily performed.

On the other hand, when welding the vertical grid 10 and the horizontal grid 11, first, the rear ends of the grid bodies 25 of the vertical grid 10 and the horizontal grid 11 are butted in a state of being orthogonal to each other. And, like the above-mentioned welding method,
It is sandwiched between a pair of electrodes from the vertical lattice 10 side and the horizontal lattice 11 side, and pressurized while energizing. Thereby, the horizontal grid 11 can be welded to the rear end portion of the grid main body 25 having a thickness smaller than the diameter of the horizontal grid 11 with the horizontal grid 11 biting.

As described above, in the present embodiment, the rear ends of the lattice main body 25 are welded to the upper and lower welding pieces 20 and 22, and the engaging portions 10a and 10b are separated from the welded portions in the expected direction. Is engaged with the upper and lower engagement pieces 21 and 23, whereby the vertical lattice 10 is attached to the upper and lower body edges 8 and 9 in a state of being supported at two points separated in the expected direction. Therefore, the vertical lattice 10 can be firmly attached to the upper and lower waist edges 8 and 9 as compared with the case where only the rear end portion of the lattice main body 25 is welded as in the related art.
Therefore, even if an external force acts in the find direction, it is possible to effectively prevent the vertical lattice 10 from bending or coming off the upper and lower welding pieces 20 and 22.

Since gaps 27 and 28 are formed between the upper and lower ends of the vertical lattice 10 and the lower surface 8a of the upper body edge 8 and the upper surface 9a of the lower body edge 9, respectively, the alumite surface is formed during the manufacturing process. When processing is performed, the gaps 27 and 2
The air can escape through the air passage 8, and air accumulation can be effectively prevented. Thereby, the vertical lattice 10
A good oxide film or the like can be formed at the joint between the upper body edge 8 and the lower body edge 9.

And an engagement bent portion 33b which is continued from the lower end thereof and slightly bent toward the upper welding piece 20 to form an "L" shape. The upper engagement piece 33 is formed with an engagement notch 33c having a width substantially equal to the width of the rib piece 26 of the vertical lattice 10 from the engagement protrusion 33a to the engagement bent part 33b. I have. The engagement notch 33c has a vertical lattice 1
The upper end of the rib piece 26 provided at the front end of the zero is engaged, and thereby the vertical lattice 10 is supported so as not to swing in the finding direction. In addition, since the engagement bending portion 33b bent in the expected direction as described above is formed at the lower end of the upper engagement piece 33, the rib piece 26 is formed when the upper body edge 31 and the vertical lattice 10 are welded. Even if it is shifted in the expected direction from the position of the engagement projection 33a, the upper end thereof does not come off from the engagement notch 33c.

Similarly, an upper edge 32a of the lower waist edge 32 is formed into an "L" shape by a welding protruding portion 22a and a welding bent portion 22b, similarly to the upper welding piece 20. The lower welding piece 22 is formed. The lower end of the lattice main body 25 of the vertical lattice 10 is welded to the lower welding piece 22 at a welding portion 22c. Also, the upper surface 32a
Similarly to the upper engaging piece 33, a lower engaging piece 34 composed of an engaging projecting part 34a and an engaging bent part 34b at the upper end thereof is formed at the outer edge of the site. This lower engagement piece 3
4, an engagement notch 34 c having substantially the same width as the rib 26 of the vertical lattice 10 is formed from the engagement projection 34 a to the engagement bent portion 34 b. The lower end of the rib piece 26 is engaged with the engagement notch 34c, thereby supporting the vertical lattice 10 so as not to swing in the finding direction.

In this case, the lower surface 31a of the upper waist 31
And between the upper end of the lattice body 25 of the vertical lattice 10 and between the upper surface 32a of the lower waist edge 32 and the lower end of the lattice body 25,
A gap is formed as in the first embodiment. The method of welding the vertical lattice 10 and the upper and lower welding pieces 20 and 22 is the same as in the first embodiment.

As described above, in the present embodiment, the rear end of the lattice main body 25 is welded to the upper and lower welding pieces 20 and 22, and the rib piece 26 is engaged with the upper and lower engaging pieces 33 and 34. Accordingly, the vertical lattice 10 is attached to the upper and lower waist edges 31 and 32 while being supported at two points at both ends in the expected direction. For this reason, the vertical lattice 10 can be firmly attached over the entire prospective direction, and sufficient strength against external force in the finding direction can be provided. Further, similarly to the first embodiment, the vertical lattice 10 and the upper and lower body edges 31, 32 are provided.
The air gap can be effectively prevented by the gap at the joint portion with the air.

Next, referring to FIG. 6, a description will be given of a grid mounting structure according to a third embodiment of the present invention. As shown in this figure, these upper waist edge 41 and lower waist edge 42 also

An upper vertical surface 41b is formed on the outer edge of the site 1a so as to extend upward from the lower surface 41a. Then, the upper end of the grid body 25 of the vertical grid 43 is attached to the upper welding piece 20 by the welding method similar to that of the first embodiment.

That is, even if the ribs 26 are to be bent around the rear end portion where the vertical lattice 43 is welded, the rib pieces 26 receive the reaction force from the upper and lower vertical surfaces 41b and 42b, so that the rib pieces 26 are held at the contact positions. . Accordingly, the front end of the lattice main body 25 does not move in the finding direction, and the vertical lattice 43 can be effectively prevented from being bent.

Further, in this embodiment, the lower vertical surface 42b of the lower body edge 42 extends downward from the upper surface 42a, and unlike the second embodiment, the upper surface 42a of the lower body edge 42 is surrounded in the expected direction. It is not formed as expected. Therefore, in the present embodiment, the upper portion of the lower trunk edge 42 can be made to have a structure in which dust, rainwater, and the like hardly accumulate without lowering the strength of the vertical lattice 43. In addition, as in the first embodiment, if the upper surface 42a is formed with a downward slope toward the outside of the site, dust and rainwater that collect on the upper surface 42a flow down to the outside of the site, and the upper portion of the lower trunk edge 42 is further removed. A structure in which dust and the like hardly accumulate can be obtained.

An engagement notch 51c is formed so that the upper end of the rib piece 26 is inserted from the outside of the site toward the inside of the site.

Similarly, an outer edge of the upper surface 52 a of the lower waist edge 52 is attached to a lower engaging piece 52 engaged with the vertical lattice 53.
The lower engagement piece 52b is formed with an engagement notch 52c for engaging the lower end of the rib 26 of the vertical lattice 53, similarly to the engagement notch 51c.

The vertical lattice 53 comprises a lattice main body 25 substantially similar to the vertical lattice 10 of the first embodiment and rib pieces 26. The upper and lower ends of the lattice main body 25 are cut off in the same manner as in the third embodiment, and the upper end of the lattice main body 25 and the upper trunk edge 5 are cut off.
A gap is formed between the lower surface 51a and the lower end of the lattice body 25 and the upper surface 52a of the lower waist edge 52 to allow air to escape. The upper and lower ends of the rib pieces 26 are cut out from the left and right, are formed in a substantially horizontal “H” shape, and define the arrangement positions of the upper and lower body edges 51, 52.
4 are formed respectively. The height of the left and right notch portions of each defining portion 54 is substantially the same as the thickness of the upper and lower engagement pieces 51b, 52b, and the distance between the left and right notch portions is determined by the direction in which the engagement notch portions 51c, 52c are found. The width is substantially the same.

As in the first embodiment, the rear ends of the lattice main body 25 are welded to the welding pieces 20 and 22 and the defining portions 54 and 54 of the rib pieces 26 are engaged with the engagement notches 5.
1c and 52c are engaged with each other.

As described above, according to the present embodiment, the vertical lattice 53 is attached so as to be combined with the upper and lower body edges 51, 52 via the defining portions 54, 54. Can be regulated with respect to each other. Thereby, assembling becomes easy, and strength after assembly can be increased.

In each of the above embodiments, the case where the lattice mounting structure of the present invention is applied to a gate has been described. However, it is needless to say that these lattice mounting structures can also be applied to a fence or a plane lattice. Nor.

0,22 and the front end of the grid body is
The upper and lower body edges 8, 9 are engaged with the same engagement pieces as the upper and lower engagement pieces 21, 23 of the first embodiment.

FIG. 8 is a front view of a lattice portion showing a first modification and a cross-sectional view in which a part is enlarged. As shown in this figure, the vertical lattice 61 is provided with rib pieces 62, 62 protruding left and right, respectively, at the center of the lattice body 25 in the expected direction. As described above, by providing the rib pieces 62, 62 at the center of the grid body 25 in the expected direction,
Compared with the above embodiments in which the rib pieces are provided only at the front end of the lattice main body in the expected direction, the strength of the vertical lattice 61 in the finding direction can be improved as a whole. Further, in the present modified example, in order to reinforce the strength of the vertical grid 61 in the finding direction, the horizontal grid 11 is provided in the same manner as in the first embodiment. Note that the vertical lattice 61 can be easily formed of a cross-section shaped member.

FIG. 9 is a front view of a lattice portion showing a second modification and a cross-sectional view in which a part is enlarged. In this modification, two or three rib portions 64 are formed on one lattice body 25 by appropriately cutting the rib pieces 62, 62 in the first modification. This lattice portion is formed by alternately arranging vertical lattices 63 having two rib portions 64 and vertical lattices 63 having three rib portions 64 so that the rib portions 64 are arranged in a staggered manner. It is configured.
Further, in the present modification, a horizontal lattice 11 is provided as in the first modification. The lattice portion thus configured has a lower strength than the first modified example by the amount that the rib pieces 2 are cut, but in this modified example,
It is designed with emphasis on design over strength.

FIGS. 10 and 11 are a front view of a lattice portion showing a third modification (1) and (2), respectively, and a partially enlarged sectional view. In this modified example, a plate-like panel 66 is provided between two adjacent vertical lattices 61 of the first modified example so as to close the gap, thereby forming a vertical lattice 65. Each vertical grid 65 is adjacent to the vertical grid 6.
5 to the vertical lattices 61 of the first modified example. Further, also in this modified example, the horizontal lattice 11 is provided as in the first modified example.
The lattice portion configured in this way has more blindfolds than the above-described modified examples by the amount of the plate-like panel 66, and is suitable when blindfolding, ventilation, and lighting are required. Further, a cutout 6 having a shape as shown in FIG.
By forming 7 and the like on the plate-like panel 66, a vertical lattice 65 rich in variations can be obtained.

FIG. 12 is a front view of a lattice portion showing a fourth modification and a cross-sectional view in which a part is enlarged. In the present modification, a lattice portion is constituted only by the vertical lattice 68 without using the horizontal lattice. Each vertical lattice 68 is formed in substantially the same shape as the vertical lattice 65 of the third modification. That is, each vertical lattice 68 is provided with a plate-like panel 66 having a long hole 69 between a pair of lattice bodies 25, 25, and a rib projecting in the left-right direction is provided at the center of each lattice body 25 in the expected direction. A piece 62 extends vertically. The rib piece 62
When the vertical lattices 68 are adjacent to each other,
Cutting is performed so that a shape substantially similar to that of the elongated hole 69 appears. Further, the central portion of the plate-like panel 66 and the tip of the rib piece 62 are formed in a state of rising in the expected direction. In this way, by forming the plate-shaped panel 66 and the rib pieces 62 three-dimensionally, the strength of the vertical lattice 68 can be increased, and the lattice portion can have a solid feeling.

FIG. 13 is a front view of a lattice portion showing a fifth modification, and a partially enlarged sectional view. In this modified example, a pair of vertical lattices 71 formed in substantially the same shape as the vertical lattice 65 of the third modified example are connected by a plurality of horizontal lattices 72 to form a set of panel lattices 73. Things. That is, in the panel lattice 73, the plate-like panel 74 curved in the finding direction is disposed so as to cover between the lattice bodies 25, 25, and the cross section “L” is provided substantially at the center of each lattice body 25 in the expected direction. The "" -shaped rib pieces 75, 75 extend vertically. In addition, a pair of vertical lattices 71,
A plurality of horizontal grids 72 are welded between the rib pieces 75 of the 71 to form a panel grid 73. As described above, by connecting the vertical lattices 71 with a plurality of horizontal lattices 72 and providing the curved panel 74 between the lattice main bodies 25, the strength of the panel lattice 73 can be increased, and the horizontal lattices can be partially formed. Can be applied to the design.

In each of the above-mentioned modifications, the modification of the lattice portion in the first embodiment has been described. However, the lattice portion is not limited to these. 22 as long as the front end is engaged with the upper and lower engaging pieces 21 and 23. Therefore, the shape and combination of the vertical lattice and the horizontal lattice may be arbitrary.
