Description

  The present invention relates to a lattice structure that prevents lattices constituting a panel body such as a flip-up gate from contacting each other.

  For example, a gate having a configuration in which a plurality of grids are crossed in a cross shape or a cross-beam shape is used not only in a swing type or a sliding door type but also in a flip-up type gate. Since these gates have a movable configuration, it is a problem that the lattices bend and deform to come into contact with each other due to the impact, and an impact sound is generated. For this reason, it is known that the lattices are strongly joined without gaps. For example, in Patent Literature 1, strong joining is performed without gaps by riveting the intersecting portions of the lattice materials.

  In addition, a sufficient gap is formed between the lattices. For example, in the face material unit of Patent Document 2, the lattice body is attached to the attachment piece in a cross shape, but a gap is formed between the lattices by the thickness of the attachment piece.

  However, when strongly joining the lattices, it is difficult to rivet the intersections of all the lattices in terms of cost and work. Further, in the configuration in which a gap is provided between the grids, it is necessary to attach a part for holding the gap to one of the grids. In this case as well, there is a problem that the work becomes complicated and the cost increases.

  The present invention solves the above-described problems, and has a simple structure, which can reduce and prevent noise generated by contact between the lattices even when an impact occurs on the panel body during opening and closing. The issue is to provide.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a panel in which a plurality of grid members are arranged to cross each other in a frame body in which an upper frame, a lower frame, and left and right vertical frames are framed in a rectangular shape. In the body, the lattice members intersect each other at a plurality of intersecting portions, and at the intersecting portion, a connecting portion where the lattice materials are connected and a non-connecting portion where the lattice materials are not connected are provided, and the connecting portion The lattice materials are connected to each other through a gap holding portion, and a gap is formed between the lattice materials of the non-connected portions.

  The invention according to claim 2 is characterized in that, in claim 1, the interval holding portion is constituted by a raised portion obtained by deforming a part of the lattice material so as to rise.

  The invention according to claim 3 is characterized in that, in claim 2, the raised portion is formed only on the lattice material on either one of the front and rear sides.

  According to a fourth aspect of the present invention, in the second or third aspect, the rear lattice material is formed in a U-shaped cross section by a bottom wall and side walls protruding rearward from the left and right sides of the bottom wall. The raised portion formed on the side grid member is formed so as to protrude from the bottom wall to the front side, and the cover material is disposed in the opening on the opposite side of the bottom wall of the rear lattice member. Features.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the lattice material is assembled in a cross shape, and an end portion of the lattice material is in a fitting groove formed on an inner peripheral surface of the frame body. Inserted and fixed, a connecting portion is provided in the vicinity of the frame body in the intersecting portion, and connected and fixed by a fixing tool.

  The invention according to claim 6 is the invention according to any one of claims 1 to 4, wherein the lattice material is assembled in a cross-beam shape, and an end portion of the lattice material is placed in a fitting groove formed on an inner peripheral surface of the frame body. It is characterized by being fitted and fixed, provided with connecting portions at regular intervals along the vertical frame of the frame, and connected and fixed with a fixture.

  According to the first aspect of the present invention, the lattice members of the connecting portion are in contact with each other via the spacing holding portion, and therefore can be reliably fixed by the fixing tool.

  Further, an interval corresponding to the height of the interval holding portion is formed between the lattice members of the non-connected portion. Therefore, especially when the panel body hits the ground etc. during opening and closing, the lattice material is also deformed by the impact, but since the front and rear lattice materials are connected and fixed to the connecting part, no noise is generated, and In the non-connecting portion, a space is formed between the front and rear lattice members, and therefore the possibility of direct contact is very small. Therefore, unpleasant noise during opening and closing can be effectively reduced or prevented, wear between the lattice members and peeling of the paint can be reduced, and durability is further improved.

  According to the invention of claim 2, since the interval holding part is constituted by the raised part deformed so as to raise a part of the lattice material, the raised part can be formed by dish processing. In this case, since the hole is formed at the center, the connecting material industry can be quickly performed by rivets and screws.

  And the space | interval of lattice materials can be obtained by the protruding part formed in the lattice material itself, and it is not necessary to attach a special space | interval holding material.

  According to the invention which concerns on Claim 3, since a protruding part should just be formed only in the grid | lattice material of either the front and back, a structure is simple.

  According to the invention of claim 4, the rear lattice material is formed in a U-shaped cross section by a bottom wall and side walls protruding rearward from the left and right sides of the bottom wall, and the rear lattice material The formed raised portion is formed so as to protrude from the bottom wall to the front side, and a cover material is arranged in the opening on the opposite side of the bottom wall of the rear lattice material, so that it looks like a square tube Since the raised portions can be formed on the lattice material, the fixing fixture is hidden by the cover material so that it cannot be seen from the outside.

  According to the invention which concerns on Claim 5 or 6, the above-mentioned effect can be acquired even when the lattice material is diagonally crossed or when it is made into a cross beam shape.

Perspective view of part of rear grid (A) and (b) are sectional views of the unconnected portion and the connected portion at the intersection of the lattice. Front view of other embodiment of panel body

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example in which a flip-up gate is an embodiment of the present invention. In FIGS. 2 to 4, reference numeral 1 is a gate (panel body), and support arms 2 are fixed to both sides of the gate 1. The base portion of the support arm 2 is rotatably attached to the support column 3. By turning the support arm 2 in the vertical direction, the gate 1 can be opened and closed up and down.

  The gate 1 has a plurality of slanted lattice members made of an extruded aluminum material in a frame 4 in which an upper frame 4a, a lower frame 4b, and left and right vertical frames 4c made of an extruded aluminum material are squarely framed. 5 and 6 are arranged so as to intersect with each other in the front-rear direction. The lattice members 5 and 6 are assembled in a cross shape, and the end portions of the lattice members 5 and 6 are held in a panel frame 7 assembled in a square shape. Specifically, as shown in FIG. 5, it is fitted and fixed in a fitting groove 8 formed on the inner peripheral surface of the frame body 4. Of the intersecting portions, the intersecting portion 10 a closest to the frame body 4 side is disposed in the vicinity of the frame body 4.

  Next, a connecting portion where the lattice members 5 and 6 are connected to each other and an unconnected portion where the lattice members 5 and 6 are not connected to each other are provided at the intersection of the lattice members 5 and 6. The connecting portion is a portion indicated by a circle in FIG. 1, and the non-connecting portion is a portion not provided with a circle. The connecting parts are all the intersecting parts 10a at the left and right ends, and in the upper and lower parts, except the intersecting part closest to the upper and lower frames 4a and 4b, the second intersecting part between the upper and lower frames 4a and 4b and the central part are the second. Part. Thus, not all intersections are connected. Some intersections are connected and some are not.

  Next, between the grid members 5 and 6 of the connecting part is connected via a gap holding part, and a gap 12 is formed between the grid members 5 and 6 of the non-connecting part.

  The space | interval holding | maintenance part is comprised by the raised part 11 which deform | transformed so that a part of the grid | lattice material 6 of the back side might be raised, as FIG. 6 shows. That is, the front lattice member 5 is simply formed in a rectangular cross section, whereas the rear lattice member 6 is composed of a bottom wall 6a and side walls 6b protruding rearward from the left and right sides of the bottom wall 6a. It has a U-shaped cross section. The rear lattice material 6 is formed with an annular raised portion 11 that protrudes to the front side at a position corresponding to the connecting portion. Such a raised portion 11 may be formed by dish-drawing from the rear surface of the bottom wall 6a to the front surface. It may be burring. The rear lattice member 6 includes a cover member 13 at the opening on the opposite side of the bottom wall 6a. An engagement piece 16 is formed on the back side of the cover material 13 and is engaged with an engagement portion 17 on the inner side of the opening end of the side wall 6 b of the lattice material 6.

  As described above, when the lattice members 5 and 6 of the connecting portion are connected to each other via the interval holding portion 11, the lattice members 5 and 6 of the connecting portion are brought into contact with each other via the interval holding portion 11. As shown to 7 (a), the clearance gap 12 only for the height of the space | interval holding | maintenance part 11 is formed between the lattice materials 5 and 6 of a non-connecting part. At the connecting portion, as shown in FIG. 5B, the front and rear lattice members 6 are fixed from the central hole of the raised portion 11 by rivets 14 and screws 15. That is, as shown in FIGS. 1, 3, and 4, all the intersecting portions on the left and right sides and the intersecting portion that is second closest to the upper and lower frames 4 a and 4 b are fixed by the rivets 14. On the other hand, it is fixed with screws 15 at the intersection of the central part. As described above, the reason for fixing the portion near the periphery of the frame body 4 with the rivet 14 and the central portion with the screw 15 is that fixing with the rivet can speed up the fixing operation, but the processing error due to riveting. This tends to be accumulated in the central portion, so that the central portion is screwed, that is, to correct a processing error manually. Of course, the lattice members of all the connecting portions may be connected and fixed with screws, rivets, or another fixing tool.

  According to the above configuration, the grid members 5 and 6 of the connecting portion are in contact with each other via the gap holding portion 11, so that the rivet 14 and the screw 15 are securely fixed as shown in FIG. be able to. In particular, when the raised portion 11 is formed by dish processing, since it has an annular structure in which a hole is formed in the center, the connecting operation can be quickly performed by rivets and screws.

  Further, as shown in FIG. 7A, a gap 12 corresponding to the height of the interval holding portion 11 is formed between the lattice members 5 and 6 of the non-connected portion. Therefore, especially when the gate 1 is moved downward and hits the ground when the opening is closed, the lattice members 5 and 6 are also deformed by the impact, but the front and rear lattice members 5 and 6 are connected and fixed to the connecting portion. Therefore, no noise is generated, and the gap 12 is formed between the front and rear lattice members 5 and 6 in the non-connecting portion, so that the possibility of direct contact is very small. Therefore, unpleasant noise during opening and closing can be effectively reduced or prevented, wear between the grid members 5 and 6 and peeling of the paint can be reduced, and durability is further improved.

  And the space | interval of the grid | lattice materials 5 and 6 can be obtained by the protruding part 11 formed in the grid | lattice material itself, and it is not necessary to attach a special space | interval holding member. Of course, a washer such as a metal or a synthetic resin may be used as the spacing member.

  The raised portion 11 may be formed on the front grid member 5 or may be provided on both the front and rear grid members 5 and 6. In the case where both the lattice members 5 and 6 are provided, the tips of both raised portions may be brought into contact with each other, so that the height of the raised portions is about half the height of the raised portions of the above-described form, and the front and rear lattice materials. The same spacing can be maintained between 5 and 6.

  Further, the rear lattice member 6 is formed in a U-shaped cross section by a bottom wall 6a and a side wall 6b projecting rearward from the left and right sides of the bottom wall 6a, and the ridge formed on the rear lattice member 6 is formed. The portion 11 is formed so as to protrude from the bottom wall 6a to the front surface side, and the cover member 13 is disposed in the opening on the opposite side of the bottom wall 6a of the rear lattice material 6, so that it looks like a square tube. Since the raised portions 11 can be formed on the lattice materials 5 and 6 and the fixing tool for fixing is hidden by the cover material 13 so that it cannot be seen from the outside, the appearance is good.

  Next, the gate 1 made of the lattice materials 5 and 6 is not limited to the cross lattice as described above. The grid pattern shown in FIG. 8 may be used. In the figure, 5a is a vertical lattice material, and 6a is a horizontal lattice material. In these lattice members 5a and 6a, the horizontal lattice member 6a is formed in a horizontally long rectangular shape longer than the vertical lattice member 5a.

  In the gate 1 having the above-described configuration, the connecting portions may be provided at regular intervals. In this case, as shown by a circle in the figure, the connecting portion is arranged around the vertical lattice member 5a having a short length, and the horizontal lattice and the vertical lattice at the intersecting portion arranged in the vertical direction are all connected. Fix it. If there is a portion that is not fixed to the horizontal lattice member 6a, bending deformation is likely to occur. The fixture may be rivets or screws.

  In the cross-girder lattice, one of the lattice members is formed with a raised portion for holding a gap, which is the same as in the above-described embodiment.

  Further, the panel body is not limited to the flip-up type gate as described above. Other panel bodies that may be impacted may be used.

  Furthermore, the raised portion is not limited to the annular structure as described above. It may be configured as a convex portion with a depressed center.
