Description

Technical Field

[0001] The present invention mainly relates to a building support fastener for attaching structures such as louvers to a building body.

Background Art

[0002] When attaching a roof (including a louver) to a building body, the roof is attached to the building body via a support fastener. And a technique for varying the inclination angle of this roof is known (see, for example, Patent Document 1). In Patent Document 1, the inclination angle of the roof is adjusted by an arm connected to the roof using a cylinder.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in Patent Document 1, since the drive arm member protrudes outside the wall surface, the design appearance is not good. Furthermore, in order to efficiently support the roof with this arm, it is necessary to set it at 45 degrees or less with respect to the wall surface, which is longer in the axial direction than the protruding length of the roof, and there is a problem that the appearance becomes worse. In addition, since the mechanism is built into the gable, there is a problem that maintenance cannot be sufficiently performed.

[0005] Also, adjusting the angle by operating the cylinder at the construction site according to the desired angle is difficult when performing it while looking at the overall appearance. When attaching louvers to the building body in a wavy manner to enhance the design, since the attachment angle of each louver is determined by design calculations in advance, if it can be fixed to that angle, the workability at the site should also be improved.

[0006] Also, even when all the angles of the louvers are made constant, if there are warps or dimensional errors in the louvers themselves, fine adjustment of the angles can be performed, and the fact that the angles remain unchanged after the fine adjustment eliminates the need for on-site workability improvement and long-term angle maintenance.

[0007] The present invention is considered in view of the above prior art, and an object thereof is to provide a building support fastener having a simple structure that can change the angle of the attachment body with respect to the attached body and can also cope with so-called fine adjustment during the angle change.

Means for Solving the Problems

[0008] To achieve the above object, in the present invention, a base end member to be fixed to the attached body, a tip end member to be fixed to an attachment body attached to the attached body, a connecting member interposed between the tip end member and the base end member, a base end side convex portion protruding from the base end member, a base end side concave portion provided in the connecting member for locking and receiving the base end side convex portion by being formed in the same shape as the cross section of the base end side convex portion so as to be non-rotatable in the circumferential direction, a tip end side convex portion protruding from the connecting member, and a tip end side concave portion provided in the tip end member for locking and receiving the tip end side convex portion by being formed in the same shape as the cross section of the tip end side convex portion so as to be non-rotatable in the circumferential direction, the base end side convex portion has a base end side point at the position of the vertex of the polygon in the cross section, the tip end side convex portion has a tip end side point at the position of the vertex of the polygon in the cross section, the side surface of the base end side convex portion connecting adjacent base end side points is flat or formed to be concave inward, the side surface of the tip end side convex portion connecting adjacent tip end side points is also flat or formed to be concave inward, and the number of the base end side points and the number of the tip end side points are relatively prime to each other, and a building support fastener is provided.

[0009] Preferably, when the base end side convex portion is received in the base end side concave portion and the tip end side convex portion is received in the tip end side concave portion, and the base end member, the tip end member, and the connecting member are integrated to form a fastener body, a strip along the axial direction of the fastener body is formed on the outer peripheral surface of the fastener body.

[0010] Preferably, on the outer peripheral surface of the base end member, an individual mark indicating its apex is displayed at a position corresponding to the base end side point, and on the outer peripheral surface of the connecting member, an individual mark indicating its apex is displayed at a position corresponding to the tip end side point.

[0011] Preferably, the connecting member is formed of a plurality of divided bodies. A base end side concave portion is formed in the base end side divided body closest to the base end member among the divided bodies, and a tip end side convex portion is formed in the tip end side divided body closest to the tip end member among the divided bodies. In the other divided bodies, a convex portion having a vertex of a polygon in a cross section to be inserted into an adjacent divided body and a concave portion for receiving the convex portion are respectively formed, and the number of the base end side point, the tip end side point, and the vertices of all the convex portions are relatively prime to each other.

Advantages of the Invention

[0012] According to the present invention, since the number of proximal-side points and the number of distal-side points are relatively prime to each other, the distal member can be changed in angle by the number of "360 degrees / (the number of proximal-side points × the number of distal-side points)" with respect to the proximal member. That is, when the position of the proximal-side points is fixed, the distal member can be rotated and fixed by the number of distal-side points, and if the position of the proximal-side points is rotated and fixed by the number of proximal-side points, it can be rotated and fixed at an angle divided by "the number of proximal-side points × the number of distal-side points" with respect to 360 degrees. When it is desired to rotate the angle of the distal member at a small angle, that is, when so-called fine adjustment is desired, the number of proximal-side points of the proximal-side convex portion may be increased. However, if it is too large, the cross-sectional shape of the proximal-side convex portion will be close to a circle, and the distance between the proximal-side points will become short. Therefore, when inserted into the proximal-side concave portion, it becomes difficult to lock in the rotational direction. Therefore, by separating these into a proximal-side convex portion and a distal-side convex portion that are relatively prime to each other, their cross-sectional shapes can be made into polygonal shapes with a small number of vertices, and thus the rotation of the proximal-side convex portion and the distal-side convex portion can be reliably suppressed. For this reason, reliable angle adjustment becomes possible.

[0013] Further, by providing a strip along the axial direction on the fastener body, it is possible to visually recognize at what angle the proximal member, the connecting member, and the distal member are displaced and connected. At this time, by displaying individual marks indicating the points at positions corresponding to the proximal-side points and the distal-side points, when it is desired to adjust to a desired angle, it can be determined by at which mark position the strip is held. Therefore, the workability at the site is improved.

[0014] Further, by forming the side surfaces of the proximal-side convex portion and the distal-side convex portion to be recessed inward, even if the number of proximal-side points and the number of distal-side points increases and the distance between each proximal-side point and each distal-side point of the proximal-side convex portion and the distal-side convex portion becomes short and the cross-section becomes close to a circular shape, since it fits tightly with the proximal-side concave portion and the distal-side concave portion, rotation of the proximal-side convex portion and the distal-side convex portion in the rotational direction is prevented.

[0015] In addition, by forming the connecting member from a plurality of divided bodies, the number of convex and concave portions can be further increased, enabling fine adjustment of the rotation angle. Each of the divided bodies can have convex portions in the shape of a polygon with a small number of vertices, so that they can be firmly fitted into the concave portions, further preventing the convex portions from rotating relative to the concave portions.

Embodiment for Carrying Out the Invention

[0017] As shown in FIGS. 1 and 2, the architectural support fastener 1 according to the present invention includes a base end member 2 to be fixed to an object to be attached such as a building body as described later, a tip end member 3 to be fixed to an attachment object such as a louver to be attached to an object to be attached as described later, and a connecting member 4 interposed between these base end member 2 and tip end member 3. The base end member 2, the tip end member 3, and the connecting member 4 are joined to each other in the axial direction and formed as a fastener main body 5 as shown in FIG. 3. A base end side convex portion 6 protrudes from the base end member 2. This base end side convex portion 6 in the example of the figure has a base end side point 7 composed of vertices of a polygon in a cross section perpendicular to the axial direction. That is, the base end side point 7 is located at the vertex when the cross section of the base end side convex portion 6 is polygonal, but the sides connecting the vertices are not limited to the sides of the polygonal shape (straight lines connecting the vertices).

[0018] A tip end side convex portion 8 protrudes from the connecting member 4. This tip end side convex portion 8 has a tip end side point 9 composed of vertices of a polygon in a cross section perpendicular to the axial direction, similar to the base end side convex portion 6. Note that both the base end side point 7 and the tip end side point 9 are arranged at the positions of the vertices of a regular polygon. That is, the positions of the base end side point 7 and the tip end side point 9 are arranged at the angles obtained by equally dividing 360 degrees by the number of the vertices. Also, the base end side point 7 and the tip end side point 9 do not necessarily need to be formed as vertices at the positions where two sides intersect, and may be a single point existing in the middle of a rounded and curved side. That is, the vertices of the polygon may be arc-shaped.

[0019] The connecting member 4 is formed with a proximal end side recess 10 for inserting and receiving the proximal end side convex portion 6. The cross section of the proximal end side recess 10 has the same shape as that of the proximal end side convex portion 6. In the examples of FIGS. 1 and 2, the side surface of the proximal end side convex portion 6 connecting adjacent proximal end side points 7 is recessed inward, and the proximal end side recess 10 has the same shape. Therefore, when the proximal end side convex portion 6 is inserted into the proximal end side recess 10, the proximal end side convex portion 6 is fixed within the proximal end side recess 10 and cannot rotate in the circumferential direction. On the other hand, the tip member 3 is formed with a tip side recess 11 for inserting and receiving the tip side convex portion 8. The cross section of the tip side recess 11 has the same shape as that of the tip side convex portion 8. In the examples of FIGS. 1 and 2, the side surface of the tip side convex portion 8 connecting adjacent tip side points 9 is recessed inward, and the tip side recess 11 has the same shape. Therefore, when the tip side convex portion 8 is inserted into the tip side recess 11, the tip side convex portion 8 is fixed within the tip side recess 11 and cannot rotate in the circumferential direction.

[0020] Here, as shown in FIGS. 4 and 5, the side surface of the proximal end side convex portion 6 connecting adjacent proximal end side points 7 may be a plane. Similarly, the side surface of the tip side convex portion 8 connecting adjacent tip side points 9 may also be a plane. That is, in the example of the figure, the proximal end side convex portion 6 and the tip side convex portion 8 have a polygonal cross-sectional shape. Even with such a shape, the proximal end side convex portion 6 and the proximal end side recess 10 mesh with each other and are locked to each other, suppressing rotation. The same applies to the tip side convex portion 8 and the tip side recess 11. However, as shown in FIGS. 1 and 2, by forming the side surfaces of the proximal end side convex portion 6 and the tip side convex portion 8 to be recessed inward, even if the number of proximal end side points 7 and tip side points 9 increases and the distance between the vertices of the proximal end side convex portion 6 and the tip side convex portion 8 becomes shorter, making the cross section closer to a circular shape, the proximal end side recess 10 and the tip side recess 11 are firmly fitted together, preventing the proximal end side convex portion 6 and the tip side convex portion 8 from rotating in the rotational direction. Therefore, it is more effective to recess the side surfaces of the proximal end side convex portion 6 and the tip side convex portion 8 inward when the number of vertices of the polygon increases. Especially in situations where fine adjustment of the rotation angle is required, it is effective because the number of proximal end side points 7 and tip side points 9 increases.

[0021] Here, the number of proximal-side points 7 and the number of distal-side points 9 are formed to be relatively prime to each other. That is, the greatest common divisor between the number of proximal-side points 7 and the number of distal-side points 9 is set to be 1. Thereby, for example, when the distal member 3 is removed together with the connecting member 4 from the proximal member 2, the connecting member 4 is slightly rotated, and the proximal-side convex portion 6 is housed in the proximal-side concave portion 10 so as to align with one of the proximal-side points 7 adjacent to the apex that was engaged with the proximal-side point 7 of the proximal-side concave portion 10, as a result, the distal member 3 is rotated by an angle corresponding to the rotation from the vertex of the polygon forming the proximal-side convex portion 6 to the adjacent vertex with respect to the proximal member 2 together with the connecting member 4. On the other hand, with the proximal member 2 and the connecting member 4 left as they are, only the distal member 3 is removed from the connecting member 4, the distal member 3 is slightly rotated, and the distal-side convex portion 8 is housed in the distal-side concave portion 11 so as to align with one of the distal-side points 9 adjacent to the apex that was engaged with the distal-side point 9 of the distal-side concave portion 11, as a result, the distal member 3 is rotated by an angle corresponding to the rotation from the vertex of the polygon forming the distal-side convex portion 8 to the adjacent vertex with respect to the proximal member 2.

[0022] For example, as shown in FIG. 1, the proximal member 2 is formed with a flange 15 for attachment to a building structure, and the distal member 3 is formed with a flange 16 for attachment to a louver. When it is desired to rotate the angle of the louver with respect to the building structure, if the distal member 3 is rotated with respect to the proximal member 2 fixed to the building structure in the above-described manner, the angle of the louver is rotated. Note that since these flanges 15 and 16 adopt appropriate shapes for the objects to be attached, they are not essential.

[0023] At this time, as described above, since the number of proximal-side points 7 and the number of distal-side points 9 are formed to be relatively prime to each other, when the distal member 3 is rotated together with the connecting member 4 and when only the distal member 3 is rotated, the rotation angles will be different. Because they are relatively prime to each other, the distal member 3 will not be rotated at the same angle when rotated together with the connecting member 4 and when rotated only by itself. Therefore, in this case, the distal member 3 can be adjusted in angle by the number of proximal-side points 7 × the number of distal-side points 9. The more the number of proximal-side points 7 or distal-side points 9, the greater the number of adjustable angles. For example, as shown in FIG. 1, when the number of proximal-side points 7 is 12 and the number of distal-side points 9 is 11, 360 degrees can be divided into 132 equal parts, that is, rotated at intervals of 2.73 degrees.

[0024] Incidentally, if one of the numbers of the proximal-side points 7 or the distal-side points 9 is made a multiple of 4, typical angles such as 0 degrees, 90 degrees, 180 degrees, and 270 degrees can be obtained as the angles for rotating the distal member 3. (For example, in the combination of 12×11, since 12 is a multiple of 4, the above typical angles can be obtained.)

[0025] Thus, since the number of proximal - side points 7 and the number of distal - side points 9 are relatively prime to each other, the distal - end member 3 can cause the proximal - end member 2 to change its angle by "360 / (the number of proximal - side points)×(the number of distal - side points)". That is, when the position of the proximal - side points 7 is fixed, the distal - end member 3 can be rotated by the number of distal - side points 9, and if the position of the proximal - side points 7 is rotated by the number of proximal - side points 7, it can be rotated at an angle divided by "the number of proximal - side points 7×the number of distal - side points 9" with respect to 360 degrees. When it is desired to rotate the angle of the distal - end member 3 at a small angle, that is, when it is desired to make a so - called fine adjustment, the number of proximal - side points 7 of the proximal - side convex portion 6 may be increased. However, if it is too large, the cross - sectional shape of the proximal - side convex portion 6 will be close to a circle, and the distance between the proximal - side points 7 will become short. Therefore, when inserted into the proximal - side concave portion 10, it will be difficult to lock it in the rotational direction. Therefore, by separating these into the proximal - side convex portion 6 and the distal - side convex portion 8 that are relatively prime to each other, their cross - sectional shapes can be made into polygonal shapes with a small number of vertices. Therefore, the rotation of the proximal - side convex portion 6 and the distal - side convex portion 8 can be reliably suppressed. For this reason, reliable angle adjustment becomes possible. In this regard, there is a meaning in interposing a connecting member 4 between the proximal - end member 2 and the distal - end member 3.

[0026] And, as shown in FIG. 3, when the proximal - side convex portion 6 is received in the proximal - side concave portion 10 and the distal - side convex portion 8 is received in the distal - side concave portion 11, and the proximal - end member 2, the distal - end member 3, and the connecting member 4 are integrated to form the fastener body 5, a strip 12 along the axial direction of the fastener body 5 is formed on the outer peripheral surface of the fastener body 5. In the example of the figure, the strip 12 is formed as a notched groove, but it may be a straight line drawn directly on the side surface of the fastener body 5, or it may be raised to form a ridge. And, as shown in FIG. 1, on the outer peripheral surface of the proximal - end member 2, individual marks 13 indicating the vertices are shown at positions corresponding to the proximal - side points 7, and on the outer peripheral surface of the connecting member 4, individual marks 14 indicating the vertices are shown at positions corresponding to the distal - side points 9. In the example of the figure, both the mark 13 and the mark 14 are numbers, and the respective vertices 7, 9 are arranged at positions corresponding to these numbers. Note that in the figures other than FIG. 1, these marks 13, 14 are omitted.

[0027] With the presence of such strips 12 and marks 13 and 14, the strip in which the strip 12 is axially connected can be provided with an angle of 0 degrees, that is, a reference angle. At this reference angle, the strip 12 of the connecting member 4 is at the numerical value 1 of the mark 13 of the base member 2, and the strip 12 of the tip member 3 is at the numerical value 1 of the mark 14 of the connecting member 4. That is, as shown in FIG. 6, the angle of 1-1 is used as a reference. When the number of the base-side points 7 is 12 and the number of the tip-side points 9 is 11 as described above, for example, when it is desired to adjust to an angle of 3-11, the strip 12 of the connecting member 4 is adjusted to the numerical value 3 of the mark 13 of the base member 2, and the strip 12 of the tip member 3 is set to the numerical value 11 of the mark 14 of the connecting member 4. By doing so, even if the angle of the base member 2 is fixed, the tip member 3 can be rotated from the reference angle of 1-1 to the angle of 3-11.

[0028] In this way, by providing the strip 12 along the axial direction on the fastener body 5, it is possible to visually recognize at what angles the base member 2, the connecting member 4, and the tip member 3 are displaced and connected. At this time, by displaying individual marks 13 and 14 indicating the vertices at positions corresponding to the base-side points 7 and the tip-side points 9, when it is desired to adjust to a desired angle, it can be determined by at what positions of the marks 13 and 14 the strip 12 is held, so that the workability at the site is improved.

[0029] In addition, when it is desired to make even finer angle adjustments and the number of proximal-side points 7 and distal-side points 9 becomes too large to increase, the connecting member 4 may be formed of a plurality of divided bodies (not shown). In this case, a proximal-side recess 10 is formed in the proximal-side divided body closest to the proximal member 2 among the divided bodies, and a distal-side protrusion 11 is formed in the distal-side divided body closest to the distal member 3 among the divided bodies. And in the other divided bodies, a protrusion having a vertex with a polygon in the cross section to be inserted into the adjacent divided body and a recess for receiving the same are respectively formed. If the number of proximal-side points 7, distal-side points 9, and the vertices of all the protrusions of the divided bodies are relatively prime to each other, even finer adjustment of the rotation angle becomes possible. Also, since the protrusions of each divided body can be made into polygonal protrusions with a small number of vertices, they can be firmly fitted with the opposing recesses, and further prevent the protrusions from rotating with respect to the recesses.

[0030] Also, as shown in FIG. 7, in order to prevent rattling in the fitting when the proximal member 2, the distal member 3, and the connecting member 4 are fitted together to form the fastener body 5, an inclined portion 17 having a chamfering process may be formed on the surfaces that are butted against each other so that they butt against each other at different angles. Alternatively, for the same purpose, as shown in FIG. 8, a washer 18 may be interposed therebetween, or as shown in FIG. 9, a stepped portion 19 may be provided.

[0031] Hereinafter, one scenario to which the present invention is applied will be described by taking a building body and a louver as an example. As shown in FIG. 10, for improving the appearance of the building 20, louvers 21 may be attached to the building wall surface, and the angles of these louvers may be made different from each other. For example, as shown in FIG. 10, the angles of the respective louvers may be finely adjusted to form a wavy shape. In such a case, as shown in FIG. 11, each louver is attached to the building body at a very delicate angle offset.

[0032] As shown in FIGS. 12 to 15, specifically, the building 20 is provided with a gable 22, and a mounting plate 23 is fixed to the gable 22 by bolts 24. On the side of the mounting plate 23 protruding from the gable 22, the flange 15 of the base end member 2 is fixed by a bolt 25. Therefore, the fastener body 5 is fixed to the mounting plate 23. On the other hand, a support plate 26 is attached to the louver 21, and the flange 16 is fixed to the support plate 26 via a bolt 27. Thus, the mounting plate 23 (building 20 or gable 22) and the support plate 26 (louver 21) are fixed to each other via the fastener body 5. As described above, by adjusting the angle of the tip member 3 with respect to the base end member 2 of the fastener body 5, the angle of the louver 21 with respect to the gable 22 can be adjusted. In addition, in order to improve the fixing strength between the mounting plate 23 and the support plate 26, the fastener body 5 penetrates in the axial direction, and a bolt 28 may be inserted therethrough. The bolt 28 may be inserted from the outside of the mounting plate 23, penetrate the fastener body 5, and be fixed from the outside of the support plate 26 with a nut 29. In the above example, the building 20 and the louver 21 are shown, but the building support fastener 1 according to the present invention can be applied to various objects as long as angle adjustment such as a folding partition is desired.

[0033] Further, the building support fastener 1 of the present invention is also effective for a panel (eaves) having a complex shape. When the panel is attached to the housing in a cantilever manner and the housing support level and the panel support level are different depending on the location, generally different-shaped fasteners are attached each time, but by using the fastener 1 of the present invention, it is possible to cope with a single one via a length-adjustable bundle member. And it can cope with a more complex three-dimensional curved surface shape, a plane, or a case where the panel itself has a complex layout.
