Abstract
Description
[Technical Field]
[0001] The present invention relates to roof mounting brackets, such as snow guard brackets and solar panel mounting brackets, that can be attached to a roof by clamping and holding the roof seam (mounting portion) of the roof. [Background technology]
[0002] BACKGROUND ART Conventionally, snow guard fittings (roof mounting fittings) have been implemented in which a slat portion (snow guard portion) is provided on a main body portion that can be mounted on a roof by clamping and holding the roof seam portion.
[0003] Further explaining the main body, a tightening bolt is installed between a pair of opposing clamping bodies on the left and right, and the lower end of each of the pair of opposing clamping bodies is configured as a clamping part that abuts against the seam portion.By tightening and rotating the tightening nut threaded onto the tightening bolt, the space between the pair of opposing clamping bodies is narrowed, and the clamping part tightens and clamps the seam portion (neck portion) of the roof, allowing it to be attached and fixed to the roof (seam portion) (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 5143859 Summary of the Invention [Problem to be solved by the invention]
[0005] The main body of a snow guard bracket (roof mounting bracket) such as that described in Patent Document 1 is shipped from the factory with the clamping nuts fully tightened onto the clamping bolts (with the pair of opposing clamping bodies completely closed and fixed together) to ensure stable transportation and prevent problems such as the bracket coming apart due to loosening of the clamping bolts or noise caused by rattles.
[0006] Since the snow guards are transported to the site in this state as shipped, in order to install them on the roof, it is necessary to loosen the tightening bolts (clamping nuts) on all of the snow guard body parts beforehand so that the seam can be inserted between the clamping parts of the pair of opposing clamping bodies, which is a very time-consuming task.
[0007] The present invention has been made in view of the current state of roof mounting hardware and seeks to solve this problem by providing a roof mounting hardware in which the clamping portions of a pair of opposing clamping bodies are kept apart so that the seam can be inserted, eliminating the need to loosen the tightening bolts beforehand on-site, and which is easy to manufacture and can be transported safely, making it highly practical. [Means for solving the problem]
[0008] The gist of the present invention will be explained with reference to the accompanying drawings.
[0009] A roof mounting bracket is provided in a main body A with a pair of opposing clamping bodies 3 each having a clamping portion 4 at its lower portion that clamps a mounting portion 2 of a roof 1 from the outside, and a tightening bolt 5 disposed in a spanning state between the pair of opposing clamping bodies 3, wherein tightening and rotating the tightening bolt 5 or tightening and rotating a tightening nut 6 threaded onto the tightening bolt 5 causes the opposing clamping bodies 3 to move closer to each other, and the clamping portions 4 tighten and clamp the mounting portion 2 from both sides, thereby mounting the main body A to the mounting portion 2, This roof mounting bracket is characterized in that a coil spring 8 is interposed between the pair of opposing clamping bodies 3, urging the pair of opposing clamping bodies 3 in a direction separating them from each other to form an insertion gap 7 between the clamping parts 4 into which the mounting part 2 can be inserted, and this coil spring 8 is arranged along the tightening bolt 5.
[0010] The roof mounting bracket according to claim 1 is characterized in that the coil spring 8 is fitted onto the tightening bolt 5 and is interposed between the pair of opposing clamping bodies 3.
[0011] The roof mounting bracket according to any one of claims 1 and 2 is characterized in that the upper parts of the pair of opposing clamping bodies 3 are hinged so that they can rotate freely, and at least one of the opposing clamping bodies 3A rotates around the hinge connection part 9 at the upper part as a fulcrum, thereby allowing the clamping part 4 at the lower part to move toward and away from each other, and the coil spring 8 is interposed between the pair of opposing clamping bodies 3 that can rotate toward and away from each other, and this coil spring 8 urges the pair of opposing clamping bodies 3 in a direction separating them from each other, thereby forming and maintaining the insertion gap 7 between the clamping parts 4 into which the mounting part 2 can be inserted.
[0012] Furthermore, the pair of opposing clamping bodies 3 are provided with insertion holes 11 and 17 through which the tightening bolts 5 are inserted, and the opposing outer surfaces around these insertion holes 11 and 17 are formed into reinforcing ribs 18 that protrude outward, so that the opposing inner surfaces around these insertion holes 11 and 17 form recessed portions 19. The recessed portion 19 is configured as a support recess 19 that supports both ends of the coil spring 8, and both ends are supported by this support recess 19 so that the coil spring 8 is interposed between the pair of opposing clamping bodies 3 and is arranged along the tightening bolt 5. This relates to the roof mounting bracket described in claim 1. [Effects of the Invention]
[0013] Because the present invention is configured as described above, the pair of opposing clamping bodies are held apart by the coil spring, and an insertion gap is formed between the clamping parts so that the roof mounting part can be inserted. This means that there is no need to go through the tedious task of loosening the tightening bolts one by one beforehand; the mounting part can be immediately inserted between the clamping parts (through the insertion gap) to temporarily install the fitting on the roof, and then the installation work on the roof can be carried out quickly. Moreover, because the coil spring is arranged along the tightening bolts, it can be easily interposed between the pair of opposing clamping bodies, ensuring mass productivity equivalent to that of existing products. Furthermore, because the biasing force of the coil spring is always acting on the tightening bolt or tightening nut via the opposing clamping bodies, the tightening bolt or tightening nut will not loosen, and rattle of the tightening bolt and the pair of opposing clamping bodies is prevented, allowing stable transportation, making this a roof mounting fitting with extremely excellent practicality.
[0014] Furthermore, the inventions described in claims 2 and 4 provide a roof mounting bracket with an even more practical configuration, in which a coil spring is interposed between a pair of opposing clamping bodies along the tightening bolt, and this configuration can be easily designed and realized with a simple structure.
[0015] Furthermore, in the invention described in claim 3, the upper parts of the pair of opposing clamping bodies are hinged so that they can rotate freely, and so by tightening the clamping bolts or clamping nuts, the opposing clamping bodies can move smoothly towards each other and the clamping parts can firmly clamp and hold the roof mounting part.Furthermore, because the pair of opposing clamping bodies are less likely to come apart, the work of interposing a coil spring between the pair of opposing clamping bodies can be easily carried out, making manufacturing easier and resulting in a roof mounting bracket with an even more practical configuration.

FIG. DETAILED DESCRIPTION OF THE INVENTION
[0017] The best mode for carrying out the present invention will now be briefly described with reference to the accompanying drawings, illustrating the operation of the present invention.
[0018] The roof mounting bracket (main body A) of the present invention, in which a coil spring 8 is interposed between a pair of opposing clamping bodies 3, which urges the pair of opposing clamping bodies 3 in a direction separating them from each other, thereby forming an insertion gap 7 into which the mounting part 2 of the roof 1 can be inserted between the lower clamping parts 4, does not require the prior work of loosening the tightening bolts as with existing roof mounting brackets of this type, and the mounting part 2 can be immediately inserted from the insertion gap 7 between the clamping parts 4 to temporarily install the main body A on the roof 1, and the mounting work to the roof 1 (tightening the tightening bolts 5 or tightening nuts 6) can then be performed quickly, resulting in excellent mounting workability.
[0019] Furthermore, the roof mounting bracket of the present invention, in which the coil spring 8 is arranged along the tightening bolt 5, can easily interpose the coil spring 8 between a pair of opposing clamping bodies 3, ensuring mass productivity equivalent to that of existing products.
[0020] Furthermore, in the present invention, the biasing force of the coil spring 8 is always acting on the tightening bolt 5 or the tightening nut 6 via the opposing clamping bodies 3, so although the clamping portions 4 are separated to form an insertion gap 7, the tightening bolt 5 or the tightening nut 6 does not loosen (come apart), and rattle of the tightening bolt 5 or the pair of opposing clamping bodies 3 is prevented, enabling stable transportation. [Example]
[0021] Specific embodiments of the present invention will be described with reference to the drawings.
[0022] This embodiment is applied to snow guard fittings for a vertically shingled roof 1 (the drawing shows a vertically shingled roof), and as shown in Figure 1, a slat section 10 with snow guard function is provided in an upright position at the end located on the eaves side of the main body section A, which can be attached and fixed to the mounting section 2 of the roof 1.
[0023] In addition, the main body portion A comprises a pair of left and right opposing clamping bodies 3 each having a clamping portion 4 at the bottom that can be clamped and fixed to the seam portion 2 serving as the mounting portion 2 (hereinafter, in this embodiment, the mounting portion 2 will be referred to as the seam portion 2) and a tightening bolt 5 that is arranged in an erected state between the left and right opposing clamping bodies 3, and is configured so that by tightening the tightening nut 6 threaded onto the tightening bolt 5, the left and right opposing clamping bodies 3 approach each other and the clamping portion 4 tightens and clamps the seam portion 2 from both outsides, thereby mounting and fixing it to the seam portion 2 (roof 1).
[0024] Specifically, as shown in Figures 2 and 3, the pair of left and right opposing clamping bodies 3 are made of rectangular metal plates that are approximately symmetrical and have a length in the front-to-back direction (the direction along the slope of the roof 1 (the length of the seam 2)), and the tightening bolts 5, which are square-root bolts, are arranged between the front and rear sides of the left and right opposing clamping bodies 3 in an erected state and prevented from rotating, and the tightening nuts 6 are threadedly attached to the tip of each of the front and rear tightening bolts 5, and the left and right opposing clamping bodies 3 are configured to move closer to each other by tightening the tightening nuts 6. It is also possible to adopt a configuration in which the left and right opposing clamping bodies 3 move closer to each other by tightening the tightening bolts 5. In the figures, reference numeral 11 denotes an insertion hole for inserting the tightening bolt 5, which is provided (formed through) one of the opposing clamping bodies 3A (the opposing clamping body 3 on the right side in Figures 2 and 3), and reference numeral 17 denotes an insertion hole (square insertion hole) for inserting the square root portion of the tightening bolt 5, which is provided (formed through) the other opposing clamping body 3B.
[0025] In addition, the left and right opposing clamping bodies 3 are each formed with a vertically elongated slit-shaped mounting groove 12 that opens at the top above the middle of the approximately middle position in the front-rear direction, and is configured so that a snow guard angle can be set in this mounting groove 12 as needed.
[0026] 3, the opposing inner plate surfaces of the lower end portions of the left and right opposing clamping bodies 3 are provided with protrusions 13 at several locations (three locations in the drawing) spaced apart in the length direction (front-to-back direction) of the opposing clamping bodies 3, and these left and right protrusions 13 are configured to abut against the neck portion of the seam portion 2 of the vertical roof 1 so as to be able to clamp and fix to the seam portion 2. In other words, the lower portions of the opposing clamping bodies 3 having these protrusions 13 are configured as the clamping portion 4.
[0027] Each of the protrusions 13 is formed as a rectangular protrusion that is formed by deforming the plate surface of the lower end of each of the left and right opposing clamping bodies 3 so that the opposing outer surfaces are recessed inward, thereby causing the opposing inner surfaces of the lower end to protrude inward in a square shape (see Figures 1 to 5). That is, the protrusions 13 are integrally formed on the plate surfaces of the lower ends of the left and right opposing clamping bodies 3 .
[0028] In the figure, reference numeral 16 denotes a mounting plate portion formed by bending the front end portion of each of the left and right opposing clamping bodies 3, and the vane plate portion 10 is mounted to this mounting plate portion 16.
[0029] In addition, in this embodiment, the pair of opposing clamping bodies 3 are hinged so that their upper parts can rotate freely, and at least one of the opposing clamping bodies 3A (the right side in Figures 2 and 3) rotates and moves around this upper hinge connection part 9 as a fulcrum, so that the clamping parts 4 at their lower parts can move towards and away from each other.
[0030] Specifically, one opposing clamping body 3A is provided with a connecting piece portion 14 that protrudes from this one opposing clamping body 3A toward the other opposing clamping body 3B.
[0031] To explain this connecting piece portion 14 in more detail, the upper part of the front side and the upper part of the rear side of one of the opposing clamping bodies 3A, which are separated by the mounting groove 12, are formed by press punching or the like into a shape having protrusions that protrude upward at two locations, one at the front and one at the back, and further, of these four protrusions, the one located at the front most side and the one located at the rear most side are bent at approximately right angles toward the other opposing clamping body 3B by press bending or the like, and these bent protrusions at the front and back form the connecting piece portion 14.
[0032] That is, one of the opposing clamping bodies 3A has connecting piece portions 14 at two locations, front and rear, on its upper part, and the upper front and rear upper edge portions where these connecting piece portions 14 are present are formed in a shape that is lower in height than the other upper edge portions (upper edge portions of the other two protruding pieces that are not bent) and the upper edge portion of the other opposing clamping body 3B (see Figures 2 and 3).
[0033] In addition, the other opposing clamping body 3B has connecting hole portions 15, into which the front and rear connecting piece portions 14 are inserted, formed (pierced) by press punching or the like at the front and rear positions on its upper side, and the left and right opposing clamping bodies 3 are connected in an opposing state by inserting the front and rear connecting piece portions 14 into these front and rear connecting hole portions 15, and the forming positions of the connecting piece portions 14 and connecting hole portions 15 are set and configured so that the upper edge portions of the left and right opposing clamping bodies 3 are arranged at approximately the same height (see Figures 2 to 5).
[0034] Furthermore, the connecting piece portion 14 and the connecting hole portion 15 are configured to have a slight insertion clearance to the extent that the heights of the upper edge portions of both opposing clamping bodies 3 do not become significantly misaligned when the connecting piece portion 14 is inserted into this connecting hole portion 15, and one opposing clamping body 3A rotates relative to the other opposing clamping body 3B via the insertion connection portion between this connecting piece portion 14 and connecting hole portion 15 (using the insertion connection portion as a fulcrum), causing the clamping portions 4 provided at the lower portions of each to move toward and away from each other. In other words, the insertion connection portion between this connecting piece portion 14 and connecting hole portion 15 is configured as the hinge connection portion 9.
[0035] In this embodiment, a coil spring 8 is interposed between the pair of opposing clamping bodies 3, which urges the pair of opposing clamping bodies 3 in a direction separating them from each other, thereby forming an insertion gap 7 between the clamping portions 4 into which the mounting portion 2 can be inserted.
[0036] Therefore, unlike existing roof mounting brackets of this type, there is no need for the troublesome task of loosening the tightening bolts 5 for each unit in advance; instead, the seam portion 2 can be immediately inserted between the clamping portions 4 through the insertion gap 7 to temporarily install the main body portion A on the roof 1, and then the tightening nut 6 can be quickly tightened to attach and fix the main body portion A to the roof 1.
[0037] Specifically, the coil spring 8 is arranged coaxially with the bolt rod portion of the tightening bolt 5 (so as to surround the bolt rod portion of the tightening bolt 5) and is thereby interposed between the pair of opposing clamping bodies 3 along the tightening bolt 5, and further, by appropriately adjusting the screwing position of the tightening nut 6 onto the tightening bolt 5 (setting the tightening nut 6 to a slightly loosened state), the coil spring 8 urges the pair of opposing clamping bodies 3 in a direction separating them from each other, so that the insertion gap 7 into which the mounting portion 2 can be inserted is formed and maintained between the clamping portions 4.
[0038] Further explaining the pair of opposing clamping bodies 3, one opposing clamping body 3A is provided with an outwardly protruding reinforcing protrusion (reinforcing rib) 18 by, for example, pressing the outer surface of the entire periphery of the edge of the bolt insertion hole 11, thereby recessing the inner surface outward into a substantially square (trapezoidal) shape, and similarly, the other opposing clamping body 3B is provided with an outwardly protruding reinforcing protrusion (reinforcing rib) 18 by, for example, pressing the outer surface of the entire periphery of the edge of the square bolt insertion hole 17, thereby recessing the inner surface outward into a substantially square (trapezoidal) shape. The inner surfaces of these reinforcing ribs 18, i.e., the inner recessed portion 19 around the bolt insertion hole 11 of one opposing clamping body 3A and the inner recessed portion 19 around the square bolt insertion hole 17 of the other opposing clamping body 3B, are configured as support recesses 19 into which both ends of the coil spring 8 can be fitted and supported in contact.
[0039] Therefore, the coil spring 8 can be easily interposed between the pair of opposing clamping bodies 3 simply by inserting the coil spring 8 between the pair of opposing clamping bodies 3 and fitting both ends of the coil spring 8 into the support recesses 19. Moreover, when both ends of the coil spring 8 are fitted into the support recesses 19, the centers of the bolt insertion holes 11 and the square bolt insertion holes 17 and the center of the coil spring 8 are positioned so as to substantially coincide. This makes it easy to insert the fastening bolts 5 into the bolt insertion holes 11 and the square bolt insertion holes 17 and simultaneously fit the coil spring 8 onto the bolt rods of the fastening bolts 5, resulting in excellent assembly workability. Furthermore, this configuration of having reinforcing ribs 18 whose inner surfaces form recesses (support recesses 19) around the insertion holes 11 and 17 through which the fastening bolts 5 are inserted is also used in existing roof mounting brackets of this type, so the coil spring 8 can be installed extremely easily using conventional products as is, without providing a new spring mounting portion or the like.
[0040] Furthermore, although the drawings show a case in which the coil spring 8 is fitted only to the tightening bolt 5 located on the side closer to the blade portion 10 (front side), a configuration in which the coil spring 8 is fitted only to the tightening bolt 5 located on the rear side may also be adopted, or a configuration in which the coil spring 8 is fitted to both the front and rear tightening bolts 5 may also be adopted.
[0041] In other words, this embodiment does not require any structural changes to the existing roof mounting bracket (main body A) of this type, such as providing a new mounting section for the coil spring 8, but instead has a simple structure in which a single part (coil spring 8) is simply added and fitted over the tightening bolt 5, making it very easy to realize and ensuring mass production equivalent to that of existing products.
[0042] Furthermore, the roof mounting bracket of this embodiment is shipped with the insertion gap 7 formed, i.e., with the clamping nut 6 slightly loosened relative to the clamping bolt 5; however, the biasing force of the coil spring 8 causes the opposing clamping body 3 to always be pressed against the bolt head of the clamping bolt 5 and the clamping nut 6, and this pressure friction force prevents the clamping bolt 5 and the clamping nut 6 from loosening (the main body A does not come apart), preventing rattling of the clamping bolt 5 and the pair of opposing clamping bodies 3, enabling stable transportation.
[0043] The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate. [Explanation of symbols]
