Description

The present invention relates to snow stop structure of the roof solar panels have been installed.

  In order to prevent the snow accumulated on the roof from sliding down the roof surface and falling from the eaves, it is common to provide a snow stop structure on the sloped roof in regions with snowfall. There is also a demand for the roof on which the solar cell panel is installed, and there is a frame body that holds the outer peripheral edge of the solar cell panel in which a snow stopper is integrally formed. However, if the snow stopper is formed integrally with the frame, it is necessary to replace the entire frame when the snow stopper is damaged. Moreover, it is necessary to manufacture separately the frame which has a snow stopper, and the frame for solar cell panels installed in the roof which does not need a snow stopper.

  On the other hand, it has been proposed to provide a snow stopper via a member for fixing the solar cell panel to the roof (see Patent Document 1). In the technique of Patent Document 1, a frame of a solar cell panel placed adjacent to a long crosspiece (rail) arranged in parallel with a space on a roof is placed, and two frames are placed. The frame is fixed to the crosspiece by a support member disposed between the bodies. And the cover which covers a support member between frame bodies is attached to the support member, and the snow stopper is provided integrally with this cover. Thereby, there exists an advantage which can use a common frame body, when installing a solar cell panel in the roof which does not need a snow stop.

  However, in the technique of Patent Document 1, since the snow stopper is attached to the crosspiece through the support member, the installation position of the snow stopper is limited to the crosspiece, and the number of snow stops is also high. Will be limited to the number of. The ease of snow sliding differs depending on various conditions such as the amount of snow, the size of the roof slope, the length of the roof flowing direction, and the direction the roof is facing. In addition, there are roofs with high importance to prevent snow from falling, such as roofs facing neighbors and public roads, and less roofs. Therefore, there has been a demand for a technique that can provide a snow stopper on the roof on which the solar cell panel is installed and that has a high degree of freedom in the position and number of snow stoppers.

Japanese Patent No. 3776631

The present invention has been made in view of the above circumstances, to provide a snow stop structure can be provided a high degree of freedom Yukitome tool roof installation position and installation number of solar panels are installed, which is an object It is.

In order to solve the above problems, the snow stop structure according to the present invention is “a snow stop structure in which a snow stop is attached on the roof on which the solar panel is installed, and is arranged adjacent to the roof. The first frame body that holds the ridge side edge of the solar cell panel that is arranged on the eave side, and the eave side of the solar panel that is arranged on the ridge side Are fixed to the roof surface so that a gap is formed below each bottom surface portion, and the snow stopper is an upper surface portion of the first frame body. A first frame locking portion that is in contact with the first frame body and extends downward from the first frame locking portion and is in contact with a side surface portion of the first frame body A base, a base extending from the lower end of the first side wall toward the second frame, and an end of the base connected to the second frame A second side wall portion extending along the side surface portion, a lower end portion extending from the lower end of the second side wall portion along the bottom surface portion of the second frame body, and the first frame locking portion. The snow stopper part extending upward from the base is integrally formed, and the dimension setting in the snow stopper is a boundary line between the first side wall part and the base part, and the second side wall. The length of the upper end of the part is shorter than the distance of the gap between the first frame and the second frame, and above the gap between the first frame and the second frame. From the state in which the snow stopper is located, the snow stopper is tilted to an angle at which the tip of the lower end does not interfere with the side surface of the second frame, and the base line is aligned with the side surface of the first frame. When the snow stopper is lowered, the snow stopper cannot be tilted any further due to interference with the second frame. Is configured such that the tip of the lower end is positioned lower than the bottom surface of the second frame, so that the snow stopper is inserted into the gap between the first frame and the second frame from above. It can be attached ".

  As the “snow stopper”, the first frame locking portion is configured to extend upward from the end that becomes the boundary with the first side wall portion, and upward from the opposite end of the first frame locking portion. And a configuration in which the first frame locking portion extends upward from between both end portions.

  The “second side wall connected to the end of the base” includes a second side wall extending in the vertical direction from the end of the base, and a second side wall extending only downward from the end of the base. And the second side wall portion extending only upward from the end portion of the base portion.

  In the snow stopper structure of this configuration, the snow stopper is prevented from dropping due to gravity because the first frame locking portion is in contact with the upper surface portion of the first frame body and locked to the first frame. . However, the base portion extends from the first side wall portion extending downward from the first frame locking portion toward the side opposite to the first frame locking portion, and further to the second side wall portion. Since the lower end portion is provided, the force acting on the snow stopper is such that the upper portion is inclined toward the second frame body due to the gravity acting on this portion. The force acting in this direction is countered by the second side wall portion extending along the side surface portion of the second frame body coming into contact with the side surface portion of the second frame body. Therefore, the snow stopper in this configuration is held by the first frame and the second frame without having to be fastened with screws or nails.

  And in the snow stopper held | maintained by the 1st frame and the 2nd frame, the snow stopper extends upwards from the 1st frame latching | locking part contact | abutted to the upper surface part of the 1st frame. For this reason, the snow stoppers naturally extend higher than the upper surface portions of the first frame body and the second frame body. Therefore, the snow stopper portion having such a configuration prevents snow from falling on the solar cell panel.

  Further, since the surface on the second frame side of the snow stopper receives the snow during snow accumulation, a force acts on the snow stopper so that the upper part is inclined toward the first frame. For the force acting in this direction, the first side wall portion that is in contact with the side surface portion of the first frame body resists, and the lower end portion that extends along the bottom surface portion of the second frame body, It resists by coming into contact with the bottom surface of the second frame. Therefore, even if a snow load is applied to the snow stopper, the posture of the snow stopper held by the first frame and the second frame is stably maintained.

  As described above, according to the snow stop structure of this configuration, since the snow stop is held by the first frame and the second frame, the first frame is used to install the solar cell panel on the roof. And a snow stopper can be installed irrespective of the member for fixing a 2nd frame to a roof surface. As a result, the amount of snowfall in the area where the solar panels are installed, the slope of the roof, the length of the roof, the direction in which the roof is facing, the importance of preventing snow from falling, etc. The installation position and number of snow stoppers can be set according to the degree.

  In the snow stop structure according to the present invention, in the above configuration, “the end portion of the base portion of the snow stop device is connected to the second side wall portion above the lower end of the second side wall portion”. be able to.

  When an external force is applied to the snow stopper so that the upper portion is inclined toward the second frame body, the second side wall portion of the snow stopper contacts the side surface portion of the second frame body as described above and resists this. In other words, the side part of the second frame body receives the force transmitted to the second side wall part via the base part. In this structure, since the edge part of a base is connected to the 2nd side wall part above the lower end of a 2nd side wall part, force is easy to be transmitted to the whole 2nd side wall part via a base part. Thereby, the side part of the second frame body can easily receive the force acting on the snow stopper and transmitted to the second side wall portion, and the snow stopper can be held more stably.

Next, the snow stop used for the snow stop structure according to the present invention is “a first frame locking portion having a flat bottom surface, and extending downward from one end of the first frame locking portion. A first side wall portion having a flat surface on the first frame locking portion side, a base portion extending from the lower end of the first side wall portion in a direction opposite to the first frame locking portion, and A second side wall connected to the end, extending in parallel with the first side wall and having a flat side opposite to the first side wall; and the base from the lower end of the second side wall It extends in the opposite direction, and has a lower end portion whose upper surface is a flat surface and a snow stop portion extending upward from the first frame locking portion.

  This is a snow stop used for the snow stop structure described above. That is, the bottom surface that is a flat surface in the first frame locking portion comes into contact with the top surface portion of the first frame body and is locked to the first frame body, and the flat surface in the first side wall portion is on the side surface portion of the first frame body. Abut. And when the external force is applied to the snow stop so that the upper surface of the second side wall portion is inclined to the second frame body side, the upper surface is in contact with the side surface portion of the second frame body and is flat at the lower end portion. When the external force is applied to the snow stopper so that the upper part is inclined toward the first frame body, it comes into contact with the bottom surface of the second frame body.

  Thereby, since the snow stopper of this structure is hold | maintained by the 1st frame and the 2nd frame, in order to install a solar cell panel on a roof, the 1st frame and the 2nd frame are fixed to a roof surface Regardless of the member to do, it can be installed on the roof where the solar cell panel is installed. Therefore, the installation position and the number of installation of the snow stoppers can be set with a high degree of freedom.

In addition to the above-described structure, the snow stopper used in the snow stopper structure according to the present invention further includes “a knob portion that bends and extends from the upper end of the snow stopper portion with respect to the snow stopper portion. Can be.

  Examples of the shape of the “knob portion” include a shape bent at a right angle with respect to the snow stopper, and a shape bent at an angle different from the right angle with respect to the snow stopper. Further, the direction in which the knob portion is bent may be on the base side or on the opposite side.

  The knob part in the snow stopper of this structure is a simple structure only bent from the upper end of the snow stopper. And since a snow stopper has a knob part, when attaching a snow stopper to a 1st frame and a 2nd frame, it is easy to grasp a snow stopper with a fingertip, and it is easy to perform attachment work. In particular, the knob provided at the upper end of the snow stopper is located at the upper end of the entire snow stopper. As will be described in detail later, by setting the length of each part of the snow stopper according to the height of the first frame and the second frame and the interval between them, the first frame and the second frame It is possible to insert the snow stopper from above into the gap with the body and attach the snow stopper to the first frame and the second frame. Therefore, since the operation of inserting the snow stopper into the gap between the first frame body and the second frame body can be performed with the knob portion located at the upper end of the snow stopper, the operation is easy and efficient. A snow stop can be attached well.

As described above, as an effect of the present invention, the snow retaining structure can be provided a high degree of freedom Yukitome tool roof installation position and installation number of solar panels are installed, it is possible to provide.

Hereinafter, the snow stopper structure of the first embodiment of the present invention using the snow stopper 1 will be described with reference to FIGS. 1 to 3.

  The snow stopper 1 extends downward from one end of the first frame locking portion 10 and the first frame locking portion 10 having a flat bottom surface, and the first frame locking portion 10 side is flat. The first side wall portion 11, the base portion 12 extending from the lower end of the first side wall portion 11 in the direction opposite to the first frame locking portion 10, and the end portion of the base portion 12 are connected to each other. The second side wall 13 extends parallel to the part 11 and is flat on the side opposite to the first side wall 11, and extends from the lower end of the second side wall 13 in the direction opposite to the base 12. The lower end portion 14 whose upper surface is flat and the snow stop portion 15 extending upward from the first frame locking portion 10 are provided. The snow stopper 1 further includes a knob portion 16 that is bent and extended from the upper end of the snow stopper portion 15 with respect to the snow stopper portion 15.

  If it demonstrates in detail, the 1st frame latching | locking part 10 is an elongate flat plate shape, and the flat plate-shaped 1st side wall part 11 is extended at right angles toward the downward direction from one of the long sides. From the lower end of the first side wall portion 11, a flat plate-like base portion 12 extends at a right angle in the direction opposite to the first frame locking portion 10. An end portion of the base portion 12 is connected to a flat plate-like second side wall portion 13 extending in parallel with the first side wall portion 11 at an intermediate position in the height direction. Further, a flat plate-like lower end portion 14 extends from the lower end of the second side wall portion 13 at a right angle in the direction opposite to the base portion 12. Further, a flat snow stopper 15 extends upward from an end that becomes a boundary with the first side wall 11 in the first frame locking part 10, that is, on a surface extending the first side wall 11. ing. A flat tab portion 16 extends from the upper end of the snow stopper 15 at a right angle in the direction opposite to the first frame locking portion 10.

  In addition, the width | variety (distance from the edge part of the 1st side wall part 11 side to the edge part on the opposite side) of the 1st frame latching | locking part 10 is set slightly longer than the width | variety of the 1st frame 20a. In the first frame locking portion 10, a protruding portion 17 protruding downward is formed at the end opposite to the first side wall portion 11 side.

  Further, as shown in FIG. 3B, the sum L1 + N1 of the length L1 of the first side wall portion 11 and the length N1 below the connecting line with the base portion 12 in the second side wall portion 13 is the first frame. It is set to be longer than the height of the body 20a and the second frame 20b (the distance between the upper end and the lower end of the side surface portion 22), specifically, slightly longer (for example, +0.5 mm to +2 mm). In addition, the length R1 between the boundary line between the first side wall portion 11 and the base portion 12 (hereinafter referred to as “base line P”) and the upper end of the second side wall portion 13 is determined by the first frame body 20a and the second frame body. It is set to be shorter than the distance between 20b (distance between the side surfaces 22), specifically, slightly shorter (for example, -0.5 mm to -2 mm).

  In addition, the snow stopper 1 of the said structure is integrally formed with the metal. Such a snow stopper 1 can be manufactured, for example, by cutting a long material having a single cross section perpendicular to the axial direction, formed by extrusion, into a desired length.

  Next, a method for constructing the snow stop structure of the present embodiment by attaching the snow stop 1 to the first frame 20a and the second frame 20b will be described mainly with reference to FIGS.

Here, the 1st frame 20a and the 2nd frame 20b to which the snow stopper 1 is attached are the same structures, and are distinguished only in the positional relationship with the snow stopper 1. FIG. More specifically, each of the first frame body 20a and the second frame body 20b has a flat plate-like side surface portion 22 extending vertically, and an upper surface portion 21 extending perpendicularly from the upper end of the side surface portion 22, A bottom surface portion 23 extending from the lower end of the side surface portion 22 in the same direction as the upper surface portion 21, and a lower surface portion 21 extending from the side surface portion 22 in the same direction as the upper surface portion 21, The lower holding part 24 which hold | maintains the edge of the solar cell panel p between, and the connection part 25 extended in parallel with the side part 22 and connecting the lower holding part 24 and the bottom face part 23 are provided. Each of the first frame body 20a and the second frame body 20b is a long material having a single cross section perpendicular to the axial direction, and can be formed by, for example, metal extrusion.

In constructing the snow stop structure, first, the first frame body 20a and the second frame body 20b each holding the solar cell panel p between the upper surface portion 21 and the lower holding portion 24 are respectively spaced below the bottom surface portion 23. It is fixed to the roof surface in the state where

  Next, the snow stopper 1 is attached. First, with the first frame locking portion 10 facing the first frame body 20a and the lower end portion 14 facing downward, the snow stopper 1 is placed in the gap between the first frame body 20a and the second frame body 20b. Position it above. Then, in a state where the base line P is substantially located on the extended surface of the side surface part 22 of the first frame body 20a, the snow stopper 1 is rotated about the base line P, and the tip of the lower end part 14 is the first frame body 20a. The snow stopper 1 is tilted at an angle that does not interfere with the extended surface of the side surface portion 22 (see the solid line or the alternate long and short dash line in FIG. 2A). As described above, the length R1 between the base line P and the upper end of the second side wall portion 13 is shorter than the distance between the first frame body 20a and the second frame body 20b. When the tool 1 is rotated to avoid interference between the tip of the lower end portion 14 and the side surface portion 22 of the second frame body 20b, the upper end of the second side wall portion 13 is also in contact with the side surface portion 22 of the first frame body 20a. Interference is avoided.

  The snow stopper 1 in this state is lowered and inserted into the gap between the first frame body 20a and the second frame body 20b (see the alternate long and short dash line in FIG. 2B). When the base line P reaches a position below the upper end of the side surface portion 22 of the first frame body 20a by a distance L1, the upper part of the snow stopper 1 with the base line P as the rotation center approaches the first frame body 20a. (Refer to the solid line in FIG. 2B), the first frame locking portion 10 is brought into contact with the upper surface portion 21 of the first frame body 20a, and the first side wall portion 11 is moved to the first frame body 20a. It is made to contact | abut to the side part 22. Thereby, the 1st frame latching | locking part 10 is latched by the 1st frame 20a.

  At the same time, the second side wall portion 13 connected to the first side wall portion 11 via the base portion 12 and extending in parallel with the first side wall portion 11 is in a state along the side surface portion 22 of the first frame body 20a. At the same time, the lower end 14 extending perpendicularly from the lower end of the second side wall 13 in the direction opposite to the base 12 is in a state along the bottom surface of the first frame 20a. In the present embodiment, the length R1 between the base line P and the upper end of the second side wall portion 13 is set to be slightly shorter than the distance between the first frame body 20a and the second frame body 20b. The portion 13 is in close proximity to the side surface portion 22 of the first frame body 20a and is in a state along the side surface portion 22. Further, since the length of L1 + N1 is set to be slightly longer than the height of the first frame body 20a and the second frame body 20b, the lower end portion 14 is very close to the bottom surface portion 23 of the first frame body 20a, and the bottom surface portion 23 (see FIG. 3A).

  Unlike the above-described method, when the tip of the lower end portion 14 of the snow stopper 1 is lowered to a position lower than the bottom surface portion 23 of the second frame body 20b (see the one-dot chain line in FIG. 2 (b)) Thereafter, the base line P is slid downward along the side surface portion 22 of the first frame 20a while rotating the snow stopper 1 in the direction in which the upper part approaches the first frame 20a with the base line P as the rotation center. Moreover, while making the 1st frame latching | locking part 10 contact | abut to the upper surface part 21 of the 1st frame 20a, the 1st side wall part 11 can be made to contact | abut to the side part 22 of the 1st frame 20a. By doing in this way, when the lower end part 14 is longer than the length illustrated in FIG. 1 thru | or FIG. 3, the height of the 1st frame 20a and the 2nd frame 20b is from the length illustrated with respect to the space | interval between both. Even when the ratio of the length of the first side wall portion to the height of the first frame body 20a and the second frame body 20b is longer than the exemplified length, the first frame body 20a and the second frame body are long. The snow stopper 1 can be attached by being inserted into the gap 20b from above.

  In other words, the snow stopper 1 is tilted to an angle at which the tip of the lower end portion 14 does not interfere with the side surface portion 22 of the second frame body 20b, and the snow stopper is arranged along the base line P along the side surface portion 22 of the first frame body 20a. When 1 is lowered, the snow stopper 1 cannot be tilted any more, that is, the first side wall 11 or the snow stopper 15 is in contact with the upper end of the side wall 22 of the second frame 20b. The length is set so that the tip of the lower end portion 14 is positioned lower than the bottom surface portion 23 of the second frame 20b, and the length R1 between the base line P and the upper end of the second side wall portion 13 is the first frame 20a. If the setting is shorter than the distance to the second frame 20b, the snow stopper 1 can be attached by inserting it into the gap between the first frame 20a and the second frame 20b from above.

  By holding the snow stop 1 on the first frame 20a and the second frame 20b as described above, the snow stop structure of the present embodiment is constructed as shown in FIG. That is, it is a snow stop structure in which the snow stop 1 is attached on the roof on which the solar cell panel is installed, and is arranged on the eaves side among the solar cell panels arranged adjacent to the roof. A first frame body 20a holding the edge of the solar cell panel on the ridge side, and a second frame body 20b holding the edge side of the solar cell panel arranged on the ridge side. The snow stopper 1 is in contact with the upper surface portion 21 of the first frame body 20a and locked to the first frame body 20a so that a gap is formed below each bottom surface portion 23. The first frame locking portion 10, the first side wall portion 11 extending downward from the first frame locking portion 10 and in contact with the side surface portion 22 of the first frame body 20 a, and the first side wall portion 11. A base 12 extending from the lower end of the base toward the second frame 20b, and an end of the base 12 connected to the second frame A second side wall portion 13 extending along the side surface portion 22 of 20b, a lower end portion 14 extending from the lower end of the second side wall portion 13 along the bottom surface portion 23 of the second frame 20b, The snow stop structure includes a snow stop portion 15 extending upward from the frame locking portion 10.

  And in said snow stop structure, the edge part of the base 12 is connected to the 2nd side wall part 13 of the snow stopper 1 in the middle of the height direction, and the 2nd side wall part 13 is the base 12 It extends along the side part 22 of the 1st frame 20a toward the up-down direction from the edge part.

  Here, in order to fix the 1st frame 20a and the 2nd frame 20b to a roof surface so that a space | gap may be formed under the bottom face part 23, respectively, for example, it is parallel to the flow direction of a roof on a roof surface The long crosspieces 40 are arranged side by side, and the first frame body 20a and the second frame body 20b are attached to the crosspieces 40 via the fixing members 30, as shown in FIG.

  The fixing member 30 will be specifically described. The fixing member 30 includes a spacer member 31 and a pressing member 32. The spacer member 31 has a pair of leg plate portions 31a placed on the upper surface of the crosspiece 40, and a top plate portion 31b connecting the upper ends of the pair of leg plate portions 31a. The pressing member 32 has a pair of elongated flat plate-like pressing portions 32a that respectively contact the upper surface portions 21 of the first frame body 20a and the second frame body 20b, and a right angle downward from the inner end portions of the pair of pressing portions 32a. A pair of upright plate portions 32b and a flat substrate portion 32c connecting the pair of upright plate portions 32b. In addition, through holes 31 c and 32 d through which the bolts 34 are respectively provided in the centers of the top plate portion 31 b in the spacer member 31 and the substrate portion 32 c in the pressing member 32.

  As a crosspiece for fixing the first frame 20a and the second frame 20b with the fixing member 30 having such a configuration, a crosspiece 40 that is a square steel pipe and has a slit 40s extending in the axial direction on the upper surface is used. Can be used. Then, the bolt 34 having the head 34a having a diameter larger than the width of the slit 40s and the male screw portion 34b having a diameter smaller than the width of the slit 40s is inverted, and inserted from the end of the slit 40s. It is located inside the slit 40 s and the male screw portion 34 b extends upward from the upper surface of the crosspiece 40. The bolt 34 in this state is slid along the slit 40 s to a desired position where the first frame body 20 a and the second frame body 20 b are fixed by the fixing member 30.

  Next, with the spacer member 31 in a state in which the pair of leg plate portions 31a face downward, the male screw portion 34b of the bolt 34 is inserted from below into the through hole 31c of the top plate portion 31b, and the pair of leg plate portions 31a are separated. The direction is made to coincide with the axial direction of the crosspiece 40, and it is placed on the upper surface of the crosspiece 40. The nut 35a is fastened to the male screw portion 34b extending upward from the top plate portion 31b, and the spacer member 31 is fixed to the crosspiece 40. In this state, the male threaded portion 34b of the bolt 34 extends further upward than the nut 35a.

Of the pair of leg plate portions 31a of the spacer member 31 fixed to the crosspiece 40, the solar cell panel p is placed while the side surface portion 22 of the first frame 20a is in contact with the outside of the leg plate portion 31a located on the eaves side. The held first frame body 20 a is placed on the upper surface of the crosspiece 40. Further, the second frame body 20b holding the solar cell panel p is placed on the upper surface of the crosspiece 40 while the side surface portion 22 of the second frame body 20b is brought into contact with the outside of the leg plate portion 31a located on the ridge side. Place. Next, the male screw portion 34b extending upward from the nut 35a is inserted from below into the through hole 32d of the pressing member 32 with the substrate portion 32c facing downward. Then, one of the pair of pressing portions 32a of the pressing member 32 is brought into contact with the upper surface portion 21 of the first frame body 20a, and one of the pair of standing plate portions 32b is brought into contact with the side surface portion 22 of the first frame body 20a. At the same time, the other of the pressing portions 32a is brought into contact with the upper surface portion 21 of the second frame 20b, and the other of the standing plate portions 32b is brought into contact with the side surface portion 22 of the second frame 20b.

The snow stopper 1 can be installed on the roof irrespective of the member for fixing the first frame body 20a and the second frame body 20b to the roof surface. Therefore, the installation position and the number of installation of the snow stopper 1 can be set with a high degree of freedom.

Since the snow stopper 15 extends from the snow stopper 1 to above the upper surfaces of the first frame body 20a and the second frame body 20b, the snow stopper section 15 prevents snow from falling on the solar cell panel p. Can be deterred.

  And in the snow stopper 1, although the 1st frame latching | locking part 10 is latched by the 1st frame 20a, from the 1st side wall part 11 extended below from the 1st frame latching | locking part 10, it is 2nd. Since the base portion 12 extends toward the frame body 20b and further has the second side wall portion 13 and the lower end portion 14 at the tip thereof, the upper portion of the base portion 20b is caused by gravity acting on this portion. When a force acts on the snow stop 1 so as to be inclined to the side, the second side wall portion 13 extending along the side surface portion 22 of the second frame body 20b contacts the side surface portion 22 of the second frame body 20b. This prevents further tilting. In the snow stopper structure of the present embodiment, the second side wall portion 13 is very close to the side surface portion 22 of the second frame body 20b and extends along the side surface portion 22. Therefore, the second side wall portion 13 is the second frame. The snow stopper 1 hardly tilts until it contacts the side surface portion 22 of the body 20b.

  Moreover, in the snow stopper 1, since the 2nd side wall part 13 is extended up and down from the edge part of the base 12, the force which acted on the snow stopper 1 so that an upper part may incline to the 2nd frame 20b side, The side surface portion 22 of the second frame body 20b is easily received via the base portion 12 and the second side wall portion 13, and the posture of the snow stopper 1 can be maintained more stably.

  In addition, since the snow stopper 1 of this embodiment has the projection part 17 in the edge part of the 1st frame latching | locking part 10, the snow stopper 1 so that an upper part may incline to the 2nd frame 20b side. Is inclined to the end of the upper surface portion 21 of the first frame body 20a, and this also prevents the snow stopper 1 from being inclined. Therefore, the snow stopper 1 is stably held by the first frame body 20a and the second frame body 20b without requiring fastening with screws or nails.

  On the other hand, in a state where a snow load is applied to the snow stopper 15, a force acts on the snow stopper 1 so that the upper part is inclined toward the first frame 20 a side. The force acting in this direction is resisted by the first side wall portion 11 in contact with the side surface portion 22 of the first frame body 20a, and extends along the bottom surface portion 23 of the second frame body 20b. Since the lower end portion 14 is in contact with the bottom surface portion 23, the posture of the snow stopper 1 held by the first frame body 20 a and the second frame body 20 b is stably maintained.

  Further, since the snow stopper 1 can be inserted and attached to the gap between the first frame body 20a and the second frame body 20b from above, the first frame body 20a and the second frame body 20b are already fixed on the roof. Even after being done, the first frame body 20a and the second frame body 20b can be held. In addition, when the first frame body 20a and the second frame body 20b are fixed on the roof via a fixing member such as the fixing member 30 exemplified above, at a position between the fixing member and the fixing member. Even if it exists, the snow stopper 1 can be attached by inserting into the gap | interval of the 1st frame 20a and the 2nd frame 20b from upper direction.

  Moreover, since the snow stopper 1 has the knob part 16 at the upper end, the snow stopper 1 can be inserted into the gap between the first frame body 20a and the second frame body 20b from above, or the base line P can be used as the rotation center. It is easy to rotate and the snow stopper 1 can be attached efficiently.

Next, the snow stopper structure of the second embodiment using the snow stopper 2 will be described with reference to FIG. The snow stopper 2 and the snow stopper 1 are different in the aspect in which the second side wall portion is connected to the end portion of the base portion.

  Specifically, the end of the base 12b of the snow stopper 2 is connected to the upper end of the second side wall 13b. As shown in FIG. 4B, the sum L2 + N2 of the length L2 of the first side wall 11 and the length N2 of the second side wall 13b is the height of the first frame 20a and the second frame 20b. More specifically, it is set to be slightly longer (for example, +0.5 mm to +2 mm). In addition, the length R2 between the base line P and the upper end of the second side wall portion 13b, that is, the length of the base portion 12b is set to be shorter than the distance between the first frame body 20a and the second frame body 20b. Is set slightly shorter (for example, -0.5 mm to -2 mm).

  Similarly to the snow stopper 1 of the first embodiment, the snow stopper 2 having such a configuration can be attached to the first frame body 20a and the second frame body 20b, and a snow stopper structure similar to the above is constructed. However, in the snow stop structure, the end of the base 12 of the snow stop 2 is connected to the upper end of the second side wall 13b, and the second side wall 13b extends downward from the end of the base 12b. It extends along the side surface portion 22 of the two-frame body 20b (see FIG. 4A).

  The snow stopper 2 of the second embodiment and the snow stopper structure using the same have the same effects as the snow stopper 1 of the first embodiment and the snow stopper structure using the same. In the snow stopper 2, since the length R2 between the base line P and the upper end of the second side wall portion 13b is the length of the base portion 12b, the length between the second side wall portion 13 and the side surface portion 22 of the second frame body 20b. Compared to the snow stopper 1 in which a gap is inevitably generated between the second side wall portion 13b and the side surface portion 22 of the second frame body 20b, the second side wall portion 13b can be brought closer to the second frame body 20b. It is also possible to set so as to be substantially in contact with the side surface portion 22.

Next, the snow stopper structure of the third embodiment using the snow stopper 3 will be described with reference to FIG. In a snow stop 3 and snow fastener 1及beauty snow stopper 2, it is different in embodiments where the second side wall portion is connected to an end of the base portion.

  Specifically, the end portion of the base portion 12c of the snow stopper 3 is connected to the lower end of the second side wall portion 13c. In other words, the base 12c and the lower end 14 are on the same plane. And as shown in FIG.5 (c), the length L3 of the 1st side wall part 11 is set longer than the height of the 1st frame 20a and the 2nd frame 20b, specifically, it is slightly long (for example, , +0.5 mm to +2 mm). In addition, the length R3 between the base line P and the upper end of the second side wall portion 13c is set to be shorter than the distance between the first frame body 20a and the second frame body 20b, specifically, slightly shorter (for example, , -0.5 mm to -2 mm).

  Similarly to the snow stopper 1 of the first embodiment and the snow stopper 2 of the second embodiment, the snow stopper 3 having such a configuration can be attached to the first frame body 20a and the second frame body 20b. A snow stop structure similar to the above is constructed, but in the snow stop structure, the end of the base 12c of the snow stop 3 is connected to the lower end of the second side wall 13c, and the second side wall 13c is the base. It extends along the side surface portion 22 of the second frame body 20b upward from the end portion of 12c (see FIG. 5A).

  Here, since the snow stopper 3 has the first side wall 11 longer than the snow stoppers 1 and 2, even if the lower end 14 is not particularly long, the side surface of the first frame 20 a is in the middle of the mounting operation. Before the base line P reaches the position of the distance L3 from the upper end in the portion 22, the first side wall portion 11 comes into contact with the upper end of the side surface portion 22 of the second frame body 20b, and the snow stopper 3 is lowered while maintaining the angle. It is easy to occur that it cannot be performed (see the solid line in FIG. 5B). In that case, in the description of the attachment method of the snow stopper 1, the first method is performed while rotating the snow stopper 3 in the direction in which the upper portion approaches the first frame 20 a with the base line P as the rotation center, in the same manner as the appended method. The snow stopper 3 can be attached to the first frame body 20a and the second frame body 20b by sliding the base line P downward along the side surface portion 22 of the frame body 20a (the chain line in FIG. 5B). See).

  The snow stopper 3 of the third embodiment and the snow stopper structure using the same are the same as the snow stoppers 1 and 2 of the first embodiment and the second embodiment, and the snow stopper structure using them. Has the effect of. In the snow stopper 3, since the first side wall 11 is longer than the snow stoppers 1 and 2, the contact area with the side surface portion 22 of the first frame 20 a is large, and the upper part of the snow stopper 3 is the first. The action of the first side wall 11 against the side surface 22 of the first frame 20a against the external force acting in the direction of tilting toward the one frame 20a is great.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the scope of the present invention as described below. And design changes are possible.

  For example, in the above, with respect to the first frame body 20a and the second frame body 20b already fixed on the roof, the snow stoppers 1, 2, and 3 are connected to the first frame body 20a and the second frame body 20. The method of attaching by inserting into the gap from above is illustrated, but the present invention is not limited to this, and after fixing one of the first frame and the second frame on the roof, a snow stopper is arranged, and this snow stopper The other of the first frame and the second frame can be fixed on the roof so as to sandwich the tool. In this case, since the first side wall and the second side wall of the snow stopper are open to the side during the attaching operation, the snow stopper is attached to the frame by driving a screw or a nail here. Is also possible. In that case, you may provide the groove | channel and the hollow which guide a screw | thread or a nail in one or both of a 1st side wall part and a 2nd side wall part. In FIG. 1, as a configuration that can be used for guiding screws and nails, a long groove 18 having a V-shaped cross section provided in the first side wall portion 11 is illustrated.
