JP 2008-196254 A

  The awning member disclosed in Patent Document 1 has a problem that it takes time to manufacture and it is difficult to obtain a sufficient strength.

  An object of the present invention is to provide an awning member molded product that is easy to manufacture and has high strength, and an awning formed by using a plurality of the same.

  The sunshade member molded article according to the present invention is such that four basic elements of a dihedral shape that is a quadrangle when viewed from above are arranged so as to be adjacent to each other on the left, right, front, back, and top and bottom. An element, a second basic element arranged on either the left or right side of the first basic element, a third basic element arranged either before or after the first basic element, and first to third It consists of a fourth basic element arranged above the basic element, and there are gaps between the basic elements, but when viewed from the maximum light-shielding direction inclined by a predetermined angle, these gaps become zero. A fractal awning member molded product in which each basic element is disposed on the butt, and the butted portion between the first basic element, the second basic element, the third basic element, and the fourth basic element is injection molded Sometimes joined together and the second basic point When the abutted portion between the third basic element is also characterized in that it is bonded during injection molding.

  Four basic elements having a tetrahedron shape that is a quadrilateral when viewed from the plane are arranged so as to be adjacent to each other in the left-right, front-back, and top-bottom directions. The first basic element at the reference position and the left and right of the first basic element A second basic element arranged in any one, a third basic element arranged either before or after the first basic element, and a fourth arranged above the first to third basic elements. There are gaps between the basic elements, but each basic element is such that these gaps are zero (substantially zero) when viewed from the maximum light-shielding direction inclined by a predetermined angle. A member for sunshade having a fractal structure in which is disposed is known.

  In this specification, “dihedral shape” means having a dihedral body part composed of two triangular plate parts, and includes a part protruding from the dihedral body part. Is also included in this.

  The awning member is, for example, installed on the roof of a building to block sunlight, and the installation surface is usually horizontal (although not limited to this). In this installation, the lower sides of the first to third basic elements are placed on a horizontal plane, and the ridge lines of the basic elements are inclined at a predetermined angle (30 to 40 ° with respect to the horizontal plane) with respect to the vertical plane. It is done. The awning member has a symmetrical central plane that bisects the first basic element and the fourth basic element in a symmetrical manner at the center thereof, and the second and third basic elements are arranged with respect to the symmetrical central plane. Are arranged symmetrically with each other. When the awning member is viewed from the direction perpendicular to the ridge line direction on the symmetrical center plane, the gap between the basic elements is smaller than the gap when viewed from the front and the plane (substantially zero and The direction that is on the symmetry center plane and that is orthogonal to the ridge line direction is the “maximum light shielding direction”. The “maximum light shielding direction” can also be referred to as a direction connecting the abutting portion between the first basic element and the fourth basic element and the abutting portion between the second basic element and the third basic element.

  In the “rectangle” when viewed from the plane, the angle of the portion of the corner portion of the first basic element at the reference position that is the corner portion of the molded member for sunshade is 90 °, and the second basic Of the corners of the element and the third basic element, the angle of the part which is the corner of the molded part for the awning is slightly smaller than 90 °, and the awning member is molded out of the corners of the fourth basic element. The angle of the portion that is the corner of the product is preferably greater than 90 °.

  The shape of the awning member molded product in the front view when the ridge line is set at the center is formed by the corners of the fourth basic element with the lower surfaces of the first, second and third basic elements as the bottom sides (slanted sides). It is preferable that the vertical angle is a right isosceles triangle of 90 °. In this case, the parts constituting each basic element (middle triangle plate part, middle triangle hole and each dihedron) are also right-angled isosceles triangles. If it does in this way, when assembling the awning member molded product, it is possible to easily align the adjacent awning member molded products by using these right isosceles triangles as a reference.

  A conventional awning member is manufactured by forming a triangular hole and a bent portion by cutting and bending a part of a plastically deformable plate material, and surrounds the size of the triangular hole. The first basic element, the second basic element, the third basic element, and the fourth basic element are joined at the abutting portion by making the size slightly smaller than the size of the three triangular plate portions. . However, in this manufacturing method, joining of the butted portion between the second basic element and the third basic element is impossible unless welding is performed later, which is disadvantageous in terms of strength. .

  In order to solve this problem, in the present invention, the awning member is an injection molded product made of synthetic resin. In the conventional manufacturing method in which a part of the plastically deformable plate material is cut and bent, the butt portion between the second basic element and the third basic element that could not be necessarily joined is joined at the time of injection molding. In this way, strength improvement is achieved.

  For example, each basic element is arranged such that four dihedrons that are quadrangular when viewed from above are adjacent to each other in the left-right, front-back, and top-bottom directions, and the first dihedron at the reference position and the first two The second dihedron arranged on either the left or right side of the face body, the third dihedron arranged on either the front or back side of the first dihedron, and the first to third dihedrons. The fourth dihedron and the butted portion between the dihedrons are joined at the time of injection molding.

  This basic element can itself be a awning member molded product (single molded product that is not an assembly of a plurality of parts) (in this case, the dihedron is the basic element in claim 1). Become.). Further, an element (extended basic element) in which the four basic elements are arranged so as to be adjacent to each other on the left, right, front, back, and top and bottom can be used as a sunshade molded member.

  At the time of injection molding, paying attention to the fact that each basic element is arranged so that there is no gap when viewed from the maximum light shielding direction inclined by a predetermined angle, the maximum light shielding direction is made to coincide with the axial direction of the injection molding apparatus. Also, in the basic element of the dihedral shape, paying attention to the fact that when viewed from the ridgeline direction, the contour shape of the same cross section is a hollow shape extending in that direction, and using this hollow shape, slide here A core is inserted. Thereby, the awning member molded article can be obtained by one injection molding. As the slide core, for example, a pair of slide cores approaching / separating along the ridgeline direction is used, and a plurality of pairs of slide cores approaching / separating along the ridgeline direction are used as necessary.

  The injection molding apparatus includes a first mold that has a convex portion corresponding to the gap and is applied from the peak side of the basic element, and a second mold that has a corrugated uneven portion and is applied from the valley side of the basic element; A cavity is formed by a slide core that moves along the ridgeline of the basic element, and one of the first and second molds is a fixed mold, and the other is a movable mold. Are arranged so as to face each other with the maximum light shielding direction of the awning member molded product as the axial direction.

  In the awning member molded product according to the present invention, through-holes are respectively provided at four corners forming a quadrangle when viewed from above, and the awning member molded products arranged next to each other are In some cases, the connection is made possible by a joint having a protrusion fitted into the through-hole of the other awning member molded product and a projection fitted into the through-hole of the other awning member molded product. The through hole is preferably provided at the same time as the injection molding, and the joint is preferably formed as a synthetic resin injection molded product. Assembling of the awning using the joint is performed at the awning installation site such as the rooftop of the building, and the awning member molded products are arranged adjacent to each other, and the adjacent awning member molded products are connected by the joint. By repeating the work, the sunshade can be assembled efficiently.

  In forming the awning, the awning is not limited to the one using the joint, but instead, the awning can be formed using the reinforcing material and the wire.

  For example, the sunshade is a unit formed by arranging a predetermined number of sunshade molded parts so that the ridge lines are continuous, and the unit is supported by a reinforcing material extending in the ridge line direction. It is said.

  As the reinforcing material, a metal wire, a metal wire, a natural fiber or a synthetic fiber rope can be used. The reinforcing material may be flexible and can be bent easily, or may not be flexible like a steel material. The reinforcing member and each awning member molded product can be fixed by, for example, an adhesive. Also, a projection is added to each awning member molded product, and holes, slits, etc. for supporting the reinforcing material are provided. You may make it form in a processus | protrusion, and you may make it fix a reinforcing material by crimping a processus | protrusion. Further, when the reinforcing material has flexibility, the reinforcing material is sequentially inserted into the through holes of the awning member molded product using the through holes provided in the respective awning member molded products. If the reinforcing material is not flexible, a wire is inserted into the through-hole provided in each awning member molding, and the reinforcing material and the awning molding are formed by this wire. And may be combined.

  The reinforcing material has a length that protrudes from the awning member molded product at both ends, and each end of the reinforcing material is fixed to a pair of supporting materials arranged opposite to each other, so that one unit is a supporting material. Fixed to. A plurality of units are arranged in parallel at a pitch corresponding to the size of the sunshade member molded product (the length in the direction orthogonal to the ridgeline direction), and the sunshade member is used in one unit on one side. To obtain a awning with a rectangular shape in plan view of the number of molded products x the length of the awning member in the ridge line direction, the other side being the number of units x the length perpendicular to the ridge line direction of the awning member molded product Can do. For example, the support member may be a frame that is supported at four corners by pillars. The support material may be installed horizontally or may be installed so as to be inclined at a predetermined angle with respect to the horizontal.

  The support material for supporting the reinforcing material is set according to the direction of the sunshade (east, west, south, north) and the elevation angle. For example, if you want to prevent sunlight during the summer day, you can set the ridge line to the south and set the elevation angle in accordance with the altitude of the sun. If you want to prevent the sun, turn the ridge line to the west and the elevation angle. Should be reduced to match the western day. In general, it is preferable to install the awning ridgeline in a substantially horizontal direction with the aim of passing most of the solar radiation in the winter and almost blocking out the solar radiation in the summer.

  By using the reinforcing material, it can be easily assembled and has excellent strength, and can easily cope with the time and direction in which it is desired to prevent solar radiation.

  According to the present invention, the awning member comprising four basic elements is an integral part of injection molding, and the first basic element, the second basic element, the third basic element, and the fourth basic element Not only the butting part, but also the butting part of the second basic element and the third basic element is joined at the time of injection molding, so that the sunshading member can be easily manufactured, and the strength of the sunshading member Will improve.

  In FIG. 7, the small triangular plate portions (11a), (12a), and (14a) forming the front surfaces of the first, second, and fourth dihedrons (11), (12), and (14) are in the same plane (front surface). The small triangular plate part (12b) that forms the side surface of the second dihedron (12) is bent to the bottom side with respect to the front surface. Is formed with a triangular small triangular hole (15). The small triangular plate portions (11b), (13b), and (14b) that form the side surfaces of the first, third, and fourth dihedrons (11), (13), and (14) are on the same plane (side surface). There is a small triangular plate part (13a) that forms the front surface of the third dihedron (13) with respect to this side surface, and the side surface of the basic element (2) A triangular small triangular hole (15) is formed. Thus, the basic element (2) includes a dihedral body portion in which two middle triangular plate portions (2a) (2b) having a small triangular hole (15) in the central portion are joined via a ridgeline (R), It has a dihedral shape composed of small triangular plate portions (protruding portions) (12b) and (13a) that are bent toward the bottom surface with respect to the triangular plate portions (2a) and (2b).

  The size of each small triangular hole (15) is slightly smaller than the size of the three triangular plate portions (11a) (12a) (14a) (11b) (13b) (14b) surrounding it. Thus, a predetermined thickness is secured between the adjacent triangular plate portions (11a) (12a) (14a) (11b) (13b) (14b), and the triangular plate portions (11a) (12a) (14a) (11b) ) (13b) (14b) are joined to each other at the butted portion. The basic elements (2), (3), (4), and (5) that are adjacent to each other on the left and right, front and rear, and top and bottom are also joined to each other by ensuring a predetermined thickness at each butted portion.

  In the awning molded part (1) composed of four basic elements (2), (3), (4) and (5), the first, second and fourth basic elements (2), (3) and (5) The middle triangular plate portions (2a), (3a) and (5a) forming the front surface are on the same plane (front surface), and the middle triangular plate forming the side surface of the second basic element (3) with respect to the front surface. Since the portion (3b) is bent toward the bottom surface side, a triangular middle triangular hole (6) is formed in the large triangular portion (1a) on the front surface. Further, the middle triangular plate portions (2b), (4b) and (5b) forming the side surfaces of the first, third and fourth basic elements (2), (4) and (5) are on the same plane (side surface). There is a middle triangle plate part (4a) that forms the front surface of the third basic element (4) with respect to this side surface. A triangular middle triangular hole (6) is formed. As a result, the sunshade molded part (1) has a dihedral body in which two large triangular plates (1a) (1b) having a middle triangular hole (6) at the center are joined via a ridgeline (R). It has a dihedral shape composed of a portion and a middle triangular plate portion (protruding portion) (3b) (4a) bent to the bottom side with respect to the large triangular plate portions (1a) (1b).

  Therefore, it is assumed that the molded part for awning (1) is a basic element, and four of them are used in the same way as the above basic elements (2), (3), (4), and (5). By arranging, an assembly of the awning member molded product (1) shown in FIG. 9 is obtained, and an awning having a necessary size is obtained by appropriately increasing the number of the awning member molded products (1) to be used. be able to.

  In the plan view shown in FIG. 2, the portion of the corner portion of the first basic element (2) at the reference position that is the corner portion of the awning member molded product (1) (the corner on the lower side of FIG. 2) The angle of the part) is 90 °, and the ridge line (R) bisects this. Of the corners of the second basic element (3) and the third basic element (4), the angle of the corner part (the corner part on the left and right in FIG. 2) that is the corner part of the sunshade molded part (1) Are equal to each other and slightly smaller than 90 °, and therefore, the portion of the corner of the fourth basic element (5) that is the corner of the awning member molded product (1) (see FIG. 2). The angle of the upper corner is greater than 90 °.

  Moreover, in the front view when the ridgeline (R) shown in FIG. 3 is set in the center, the awning member molded product (1) has the first, second and third basic elements (2) (3) (4 ) With the bottom surface (the hypotenuse) as the base (slope side), the apex angle formed by the corners of the fourth basic element (4) is a 90 degree right angled isosceles triangle. Medium triangle plate (2a) (2b) (3a) (3b) (4a) (4b) (5a) (5b), medium triangle hole (6) and element (2) (3) (4) (5) Each dihedron (11) (12) (13) (14) is also a right-angled isosceles triangle. Therefore, when assembling the awning member molded product (1), by using these right isosceles triangles as a reference, it is possible to easily align the adjacent awning member molded products (1). it can. Each basic element (2) (3) (4) (5) Middle triangle plate (2a) (2b) (3a) (3b) (4a) (4b) (5a) (5b), Mid triangle hole (6 ) And each of the dihedrons (11), (12), (13), and (14) are shaped so that the shape in the front view when the ridgeline (R) shown in FIG. Therefore, the contour shape is an unequal side obtuse triangle.

  In the bottom view shown in FIG. 4, in the fractal structure formed from the conventional plate material, the small triangular plate portion (12b) bent to the bottom surface side of the second dihedron (12) indicated by the arrow P and the second two Since the abutting portion with the small triangular plate portion (13a) bent to the bottom side of the face piece (13) is a free end, the strength is low and it is difficult to maintain the shape. In the awning molded part (1), the small triangle plate part (12b) bent to the bottom surface side of the second dihedron (12) and the small triangle bent to the bottom surface side of the third dihedron (13) A predetermined thickness is secured also at the abutting portion with the plate portion (13a), and the second dihedral body (12) and the third dihedral body of each basic element (2) (3) (4) (5) As a result, the strength of the basic elements (2), (3), (4), and (5) of the sunshade molded part (1) is greatly improved.

  In addition, when forming the awning member molded product (1) by the basic elements (2), (3), (4), and (5), it was bent to the bottom side of the second basic element (3) indicated by the arrow Q A predetermined thickness is secured at the abutting portion between the middle triangle plate portion (3b) and the middle triangle plate portion (4a) bent to the bottom surface side of the third basic element (4), and the second basic configuration. The element (3) and the third basic component (4) are joined together, whereby the strength of the awning member molded product (1) is further improved.

  That is, in the fractal structure formed from the conventional plate material, as the number of elements increases, the number of unjoined butted portions also increases and the strength decreases. In the member molded product (1), since there is no butt portion that is not joined, even if the number of elements increases, a decrease in strength is prevented.

  The awning member molded product (1) is formed with the triangular holes (6) and (15) having different sizes as described above, so that the awning member molded product (1) is shown in FIGS. In any of the drawings up to this point, there are gaps at multiple locations (the portions not covered by the triangular plate portions (3b) (4a) (12b) (13a) beyond the triangular holes (6) and (15)). There is a shape. When the awning member molded product (1) is viewed obliquely from above with the ridge line (R) in front (corresponding to viewing from the sun direction), as shown in FIG. 5, the small triangular hole (15) Is blocked by the folded small triangular plate (12b) (13a), and the middle triangular hole (6) is folded by the bent middle triangular plate (3b) (4a). The gap in the member molded product (1) is substantially zero, thereby improving the light shielding property. Each triangular hole (6) (15) has an effect of improving ventilation, thereby realizing both light shielding properties and good ventilation.

  As shown in FIG. 6, the awning member molded product (1) is a small triangular plate bent toward the bottom surface side of the second dihedron (12) indicated by the arrow P as seen from above in the ridgeline direction. The first basic element (2) (and this) is obtained by joining the butted portion of the small triangular plate portion (13a) bent to the bottom surface side of the portion (12b) and the third dihedron (13). Each small triangular plate (11a) (11b) of the first dihedron (11) of the fourth basic element (5) on the other side (and the fourth dihedron (14) on the other side) The second and third dihedrons (12) of each small triangular plate (14a) (14b)) and the first basic element (2) (and the fourth basic element (5) beyond this). 13) Each of the small triangular plate portions (12b) and (13a) bent to the bottom side has a hollow cylindrical portion (first cylindrical portion) (7) having a rhombus cross section and extending in the ridgeline direction. Is formed. Similarly, in the second and third basic elements (3) and (4), the small triangular plate portions (11a) and (11b) of the first dihedron (and the fourth dihedron (14 ) And the small triangular plate portions (12b) (13a) bent to the bottom side of the second and third dihedrons (12) and (13), Two hollow cylindrical portions (second cylindrical portions) (8) extending in the ridge line direction having a rhombic cross section and half the length of the first cylindrical portion (7) are formed.

  Further, the middle triangular plate portion (3b) folded to the bottom surface side of the second basic element (3) indicated by the arrow Q and the middle triangular plate portion (4a) folded to the bottom surface side of the third basic element (4). ), The second and third dihedrons (12) of the first basic element (2) (and the fourth basic element (5) on the other side) are joined. 13) small triangular plate portions (12a), (12b), (13a), (13b) and middle triangular plate portions (3b) (4a) bent to the bottom side of the second and third basic elements (3), As a result, a hollow cylindrical portion (third cylindrical portion) (9) having a V-shaped cross section and extending in the ridgeline direction is formed. The peripheral walls of the cylindrical portions (7), (8), and (9) are cut out at locations corresponding to the gaps (triangular holes (6) and (15)).

  Paying attention to the shape shown in FIG. 6, slide cores (43) (44) (45) having a cross-sectional shape corresponding to the cross-sectional shape of the cylindrical portions (7), (8), and (9) are replaced with the cylindrical portion ( 7) Insert into the inside of (8) and (9) from both sides in the ridgeline direction (front side and back side of the paper surface of FIG. 6), and awning by a pair of molds (41) and (42) from the top and bottom sides of FIG. It can be seen that the awning member molded product (1) can be obtained by injection molding by sandwiching the member molded product (1).

  That is, in order to obtain this awning member molded product (1), as shown in FIG. 8, it has a V-shaped concave surface (41a) and is applied from the mountain side of the awning member molded product (1).

These joints (35), (36) and (37) can be obtained as injection molded articles made of synthetic resin.

  When assembling the awning using the joints (35) (36) (37), for example, the awning member moldings (1) are placed on the right side and the rear side of the awning moldings (1) arranged at predetermined positions. Side by side, these are joined by a first joint (35), and then a new awning part molding (1) is placed on top of the three awning part moldings (1) joined together, and these are joined together in the first and It is only necessary to connect the second joints (35) and (36), and by repeating this operation, an arbitrary number of sunshade molded parts (1) can be arranged on the left, right, front, back, and top and bottom. The sunshade can be assembled very efficiently.

  In forming the awning, it is not limited to the one using the joint (37), but instead, as shown in FIG. 10, using the reinforcing material (41) and the wire (42), An awning can also be formed.

  In FIG. 10, a single unit (40) is formed by arranging a predetermined number of sunshade molded parts (1) so that the ridge lines (R) are continuous. It is supported by a reinforcing material (41) extending in the (R) direction. A plurality of units (40) thus obtained are arranged in parallel to form an awning.

  Here, between the adjacent awning member molded products (1), use one of the awnings using the through holes (31) (32) (33) (34) provided in the awning member molded product (1). The through hole (31) (32) (33) (34) of the molded member for the product (1) and the through hole (31) (32) (33) (34) of the other molded product for the sunshade (1) The ends of the wires (42) are connected to each other by being inserted through the wires (42). At this time, the reinforcing member (41) and each sunshade molded member (1) can be coupled by winding the wire (42) around the reinforcing member (41). The reinforcing material (41) and each sunshade molded member (1) may be bonded in advance with an adhesive or the like.

  When installing the awning using the unit (40) formed as described above, use a support material of a high-strength material such as metal (for example, a U-shaped iron angle) to cover the awning. The frame along the outer edge of the frame is manufactured, holes for passing the reinforcing material (41) are formed at the required intervals on the two opposite sides of the frame, and the end of the reinforcing material (41) is fixed to the frame. By doing in this way, the sunshade according to the target area and shape can be made. Furthermore, the awning can be installed at a predetermined height by supporting the four corners of the frame with metal posts (for example, aluminum angles).

  According to the awning obtained in this way, it is easy to assemble by using the reinforcing material (41), and it is easy to adapt to the size and shape of the place where you want to install the awning, and you want to prevent solar radiation It is easy to deal with time and direction. In addition, due to the connection by the reinforcing material (41), the awning does not partially fall in a lump with respect to snow accumulation or the fall of foreign matter from above, and the strength is excellent.
