Description

[Detailed description of the invention] The present invention relates to a corner piece used for a rhombic lattice door, and more specifically, the lattice frame is assembled into a rectangular shape with frame members each having a substantially inward U-shaped cross section,
In manufacturing a rhombic lattice door, in which a plurality of lattice members each having a substantially rectangular cross section are assembled in a rhombus shape so that they overlap from the front side and the back side of the lattice frame, the lattice frame is The present invention relates to a corner piece used to interconnect abutting ends of frame members at a corner and to fix an end of the grid material inserted into the corner to the grid frame.

In the production of conventional rhombus lattice doors, for example, metal plates are bent at right angles and placed against the butt ends of the vertical and horizontal frames that make up the lattice frame, and then connected by welding or screwing. I was trying to do it, but
In the case of welding, positioning is time-consuming, and even in the case of screw fixing, the ends of the screws protrude into the outer peripheral end surface of the lattice frame, causing inconvenience.Furthermore, in the case of such conventional products, the corners of the lattice frame When the lattice materials are arranged so that they are overlapped from the front side and the back side of the lattice door as described above, the end of the lattice material that enters into the front side of the lattice door is Since there is a step between the front side and the back side grid material arrangement surface, a space corresponding to the step is created on either the front or back side of the corner part, and therefore the end of the grid material inserted into the corner part It became difficult to fix the lattice door, and in the case of large or low cases, the lattice door was left unfixed, which caused rattling and noise when the lattice door was used.

In view of the above, the present invention aims to provide a corner piece that can eliminate the conventional inconveniences, and one embodiment thereof will be described below in detail with reference to the drawings.

FIG. 1 shows a schematic front view of the entire rhombus lattice door 1 seen from the front side, FIG. 2 shows an enlarged detailed front view of the upper part of this rhombus lattice door 1 seen from the back side, and FIG. The figure shows a cross-sectional view. In this diamond lattice door 1, a rectangular lattice frame 4 is constituted by upper and lower horizontal frame members 2, 2 and left and right vertical frame members 3, 3, and within this lattice frame 4, a plurality of lattice members 5... The horizontal frame members 2 forming the lattice frame 4 are assembled in a diamond shape so as to overlap each other from the front side and the back side of the lattice door 1.
The vertical frame members 3 are made of extruded aluminum and have a substantially inwardly U-shaped cross section, and the lattice member 5 is made of a similar material and is formed into a rectangular tube shape.

FIG. 4 shows the abutting ends of the frame members 2 and 3 at the corners of the rectangular lattice frame 4 that are connected to each other in the production of the diamond lattice door 1, and the ends of the lattice members 5 inserted into the corner parts. This figure shows a corner piece 6 according to the present invention for fixing the lattice frame 4 to the lattice frame 4, and is formed by integrally molding a synthetic resin material such as nylon resin. This corner piece 6 is composed of a right-angled chevron-shaped piece 7 in which two pieces 7a, 7a each having a cross-sectional shape that can be fitted into the U-shaped cross-sectional frame members 2, 3 intersect in a right-angled chevron shape. A width 8w is provided on one side of the right-angled chevron-shaped piece 7, and extends along a line that approximately bisects the corner angle of the right-angled chevron-shaped piece 7, and is sufficiently wider than the width 5w of the rectangular cylindrical lattice material 5.
and a depth 8d approximately equal to the thickness 5t of the lattice material 5. A groove 8 for inserting the end of the lattice material is formed, and a frame is provided at each end of the right angle chevron-shaped piece, that is, at the outer end of each piece 7a. Hole 10 for screwing in the right angle connection screw 9
are provided so as to open on both sides of the right angle chevron-shaped piece 7, and in the center of the groove 8, a hole 12 for inserting a screw 11 for fixing the end of the lattice material is provided in parallel with the screw hole 10. It is installed through. Furthermore, each piece 7
As is clear from FIG. 5, the outer end surface of the piece 7a
exhibits an inclined shape that is oblique to the longitudinal direction of the
Furthermore, claw strips 13 and ridges 14 are formed as anti-slip means on the portions of the right-angled chevron-shaped pieces 7 that come into contact with the frame members 2 and 3, that is, on the outer end surfaces and on both the front and back sides.

To manufacture the diamond lattice door 1 using the corner pieces 6 having the above structure, first, as shown in FIG. The ends of each vertical frame member 3 are butted, and the corner piece 6 is fitted to the abutting end of the corner, and the back side of each of the horizontal frame member 2 and the vertical frame member 3 (the side having channels 2a and 3a) is The frame member right angle connection screws 9 are screwed into each screw hole 10 of the corner piece 6 through the provided holes 15 and 16, and each horizontal frame member 2 and each vertical frame member 3 are connected and fixed at right angles to each other to form a lattice frame 4. form. Note that when fitting and arranging the corner pieces 6 at the corner abutting ends, it is important to note that among the lattice materials 5 arranged in the lattice frame 4, the lattice that is inserted into the corner part of the lattice frame 4 Since the material 5 is located on either the front side or the back side of the lattice frame 4 due to the overlapping relationship, it is necessary to take this into consideration beforehand when arranging the corner pieces 6.
For example, referring to FIG. 2, this figure shows the lattice frame 4 viewed from the back side. Since the lattice material 5 is biased toward the back side of the lattice frame 4, the corner piece 6 is arranged with its lattice end insertion groove 8 facing the back side of the lattice frame 4, and the corner piece 6 on the right side In this case, since the lattice material 5 inserted into the corner is biased toward the front surface of the lattice frame 4, the corner piece 6 placed here is oriented in the opposite direction to the left corner piece 6, that is, the groove 8 is directed toward the front side of the lattice frame 4.

After forming the rectangular lattice frame 4 as described above, the lattice members 5 are assembled into a rhombus shape by arranging them so that they overlap obliquely from the front side and the back side of the lattice frame 4. At each corner, the end of the lattice material 5 is fitted into the groove 8 of the corner piece 6, and as shown in FIG. screw 11
is screwed into the hole 17 at the end of the grid material 5 and inserted into the hole 12 of the corner piece 6, or the same screw 11 is screwed into the hole 12 of the corner piece 6 through the hole 17 at the end of the grid material 5, or alternatively. The ends of the grid members 5 are fixed to the corner pieces 6 by screwing the same screws 11 through the holes 12 of the corner pieces 6 into the holes 17 at the ends of the grid members 5. In addition, the ends of the grid members 5 other than the ends of the grid members 5 that protrude into the corner portions are such that the ends of the grid members 5 arranged on the front side and the ends of the grid members 5 arranged on the back side are opposite to each other. The frame members 2 and 3 are fitted into each horizontal frame member 2 and each vertical frame member 3 in a superposed state according to the relationship, and are screwed into the frame members 2 and 3 from the back side of each of these frame members 2 and 3. Fixed against. Furthermore, the grid material 5 on the surface side
The portion where the lattice material 5 on the back side and the lattice material 5 on the back side overlap each other at the intermediate portion may also be fixed with appropriate screws 19.
As mentioned above, all screws 9, 11, and 18 are attached to the frame material 2,
The corner piece 6 or the lattice material 5 is screwed into the corner piece 6 or the lattice material 5 from the back side of the frame material 3 so that the screw head and screw end are not visible from the front surface side of the frame material 2, 3.
(see figure). As explained above, the corner piece for a rhombus lattice door of the present invention is composed of a right angle chevron piece that fits into the corner part of a lattice frame made of a frame material with a substantially inward U-shaped cross section. When connecting the ends at right angles, positioning becomes easy and accurate connection can be performed. In addition, a groove for inserting the end of the lattice material, which extends in a direction that bisects the corner of the right angled piece and is sufficiently wider than the width of the lattice material, is formed on one side of the right angled angled piece. Holes for screwing the frame material connection screws and holes for inserting the grid material end fixing screws are provided in the center of the groove so as to open on both sides of the right angle chevron, so that the grid material When the lattice material is placed so that it overlaps from the front side and the back side of the lattice door, a step is created on the lattice material arrangement surface on both the front and back sides, and the lattice material inserted into the corner part of the lattice frame is placed on one side of the lattice door. Even if the lattice material is located off to the side, the space created on the other side of the lattice door at the corner portion is compensated for by the corner piece, and the part where the lattice material enters the corner portion is filled with the corner piece. It can be held in the groove, and by screwing the protruding part of this lattice material, it is possible to securely fix this lattice material and prevent rattling etc.
In addition, since the groove is formed sufficiently wider than the width of the lattice material, it has the feature that it can be applied to lattice doors with various oblique angles of the lattice material. Even if the space created by the step is on either the front or back side of the lattice door, it is sufficient to turn the piece upside down and arrange it as appropriate.Moreover, since the hole provided in the piece is open on both sides, it can be used in any case. The screws can be screwed in from the back side of the frame material that makes up the lattice frame, so the screw heads and screw ends are not exposed on the front side of the lattice frame, and at the same time, the screw ends can be screwed in on the outer peripheral edge of the lattice frame. does not stand out,
The appearance and function of the lattice door will not be impaired.
