An embodiment of the present invention will be described below with reference to the drawings.
The snow stopper 1 according to the present invention includes a plurality of solar cell panels 3 laid on the roof R via the gantry 2 before and after the adjacent solar cell panels 3a and 3b before and after the roof R in the flow direction Y. A clamp upper part 6 and a lower clamp part 7 made of an extruded forged product having the same cross-sectional shape, and a bolt 8 for vertically connecting them are mounted in a gap S constituted by the end frames 4 and 5.

  The clamp upper portion 6 is provided with a barrel portion 9 having a concave cross-sectional shape in a side view in which the depth D is set slightly shorter than the gap S so that the depth D can be inserted vertically through the gap S, and the front and rear walls 9a, 9b of the barrel portion 9 are provided. The front and rear end portions 10 and 10a disposed on the upper end surfaces 4a and 5a of the front and rear end frames 4 and 5 at the appropriate height position on the outer side surface are projected horizontally with the same width W as the front and rear walls 9a and 9b. 4 and 5 are constructed so as to be installed between the upper end surfaces 4a and 5a.

Accordingly, the central portion 9c interposed between the lower ends of the front and rear walls 9a and 9b so as to correspond to the gap S is disposed so as to be detachable into the upper opening S1 of the gap S with respect to the front and rear end portions 10 and 10a. The upper portion 4a, 5a of the upper and lower end frames 4, 5 of the clamp upper portion 6 has the central portion 9c in the upper opening S1 in the above-described installation state, so that the clamp upper portion 6 in the gap S cannot be rotated. ing.
The upper portions of the front and rear walls 9a and 9b projecting upward from the front and rear end portions 10 and 10a are formed as snow stopper protrusions 11 and 11a, and an insertion hole 12 is formed through the screw portion 8b of the bolt 8 in the center of the central portion 9c. It is penetrating.
The lateral width W of the upper clamp portion 6 is appropriately set to a length. However, because the length is the same as that of the snow stopper pieces 11 and 11a, a longer one is preferable.

The lower part of the clamp 7 has the same sectional shape as that of the upper part of the clamp 6 in a side view, and is turned upside down, and the width W1 and the depth D1 (the same length as the depth D) can be inserted vertically through the gap S than the gap S. A body portion 13 having a rectangular shape in plan view, which is set to be slightly shorter, is provided, and the gap S can be vertically inserted at an appropriate height position on the outer surface of the front and rear walls 13a and 13b of the body portion 13 with a lateral width W2 of the same length. The set protrusions 14 and 14a are at least above the trunk 13 as shown in the illustrated example (almost all of the trunk 13 when the protrusions 14 and 14a protrude from the lower end of the outer surface of the front and rear walls 13a and 13b). In a non-rotatable state fitted in the lower opening S2, the front and rear end frames 4 and 5 are horizontally projected so as to be able to touch the lower end surfaces 4b and 5b.
Further, a screw hole 15 into which the bolt 8 is screwed is screwed in a central portion 13c interposed between the upper ends of the front and rear walls 13a and 13b in the body portion 13.

  The bolt 8 is set so that the bolt head 8a is secured to the upper surface of the central portion 9c of the trunk portion 9 in the upper clamp portion 6 and the screw portion 8b is allowed to pass through the insertion hole 12 downward. The central portion 13c of the body portion 13 of the clamp lower portion 7 is screwed to the tip of the screw portion 8b whose length is set so as to protrude downward from the lower opening S2 of the gap S in the above-described erected state of the upper portion 6.

Next, the attachment method of the snow stopper 1 comprised as mentioned above is demonstrated.
First, the clamp lower portion 7 of the snow stopper 1 configured as described above is arranged so that the tips of the projecting pieces 14 and 14a coincide with the longitudinal direction of the gap S (the same as the direction X of the roof R). The upper part of the clamp 6 is installed between the upper end surfaces 4a and 5a of the front and rear end frames 4 and 5 (see FIG. 3).

Thereby, the snow stopper 1 can be temporarily fixed and held in the gap S without requiring any support means, and the front and rear end portions 10 and 10a of the clamp upper portion 6 are the upper end surfaces of the front and rear end frames 4 and 5, respectively. 4a and 5a are touched, and the central portion 6c between the front and rear end portions 10 and 10a is arranged with a step in the upper opening S1 of the gap S, so that the upper clamp portion 6 does not rotate freely. The snow stopper protrusions 10 and 10a can be arranged along the longitudinal direction of the gap S, that is, the longitudinal direction X of the roof R so that the snow stopper surface faces the flow direction Y of the roof R.
By sliding the snow stopper 1 along the gap S in this state, the snow stopper pieces 11 and 11a can be easily positioned.

Next, as shown in FIG. 4, by rotating the bolt head 8a exposed on the upper surface of the central portion 9c of the clamp upper portion 6 by 90 degrees while rotating upward, the projecting pieces 14 and 14a of the lower clamp portion 7 are moved to the front and rear end frames 4, 5 is made to touch the lower end surfaces 4b and 5b.
As a result, the body 13 above the projecting pieces 14, 14 a in the lower clamp portion 7 can be inserted and held in the lower opening S 2 of the gap S so that the lower clamp portion 7 cannot be rotated.

In this state, the front and rear end frames 4 and 5 are sandwiched between the upper clamp portion 6 and the lower clamp portion 7 by screwing the bolt 8.
In this manner, the snow stopper 1 is mounted in the gap S between the adjacent solar cell panels 3a and 3b before and after the flow direction Y of the roof R. Therefore, the longitudinal direction of the gap S, that is, the longitudinal direction X of the roof R. Can be installed freely without limiting the number or mounting position.

  In the process from the state shown in FIG. 3 to the state shown in FIG. 4 of the snow stopper 1, it is more preferable to rotate the bolt head 8a upward by 90 degrees as described above. For example, after the bolt head 8a exposed on the upper surface of the central portion 9c of the clamp upper portion 6 is once rotated by 90 degrees, the bolt 8 is pulled upward together with the clamp upper portion 6 and then only the clamp upper portion 6 is lowered, and this is again the upper end surface. It is also possible to adopt a method such as laying between 4a and 5a. As a result, if the state of the snow stopper 1 shown in FIG. 3 is changed to the state shown in FIG. 4, the method of the process is not limited at all. .

  In the present embodiment, the lower clamp portion 7 is different from the upper clamp portion 6 in the width W and W1 and upside down. Even so, it is possible to sandwich the front and rear end frames 4 and 5 together with the clamp upper portion 6 as described above.

  Further, in the present embodiment, a case in which the snow stopper 1 is attached to the solar panel group 3 laid on the roof R provided with Japanese tiles via the mount 2 is shown above. If the solar panel group 3 is laid on the roof R and the gap R between the solar panel 3a and 3b adjacent to the roof R in the flow direction Y is present, the snow can be stopped regardless of whether it is newly installed or existing. Since the tool 1 can be attached, the structure of the gantry 2 does not have to be limited at all, and the roof R may not be a Japanese roof tile but a flat roof tile or a slate roof.

  In the above description, the snow stop 1 is attached to the gap S between the solar panels 3a and 3b adjacent to each other before and after the flow direction Y of the roof R. Hereinafter, the solar panel group shown in FIG. 3, the snow stopper 16 attached to the front end in the flow direction Y of the roof R of the solar panel 3a located at the eaves will be described with reference to FIGS.

This snow stopper 16 is made of an L-shaped plate material in which the upper end of the vertical plate portion 16a is formed with a snow stopper protrusion piece 17, and a screw insertion hole 16c is formed through the center of the horizontal plate portion 16b.
And the snow stopper 16 is attached to the bracket 18 holding the front end frame 4 of the solar cell panel 3a on the front end of the gantry 2.

The bracket 18 is fixed by a screw portion 19a protruding upward in a fixture 19 attached to the gantry 2 and a nut 19b, and the screw portion 19a protruding further upward from the nut 19b is inserted into a screw insertion hole of the snow stopper 16. The snow stopper 16 is fixed by fastening with a nut 20 and a washer 21 separately through 16c.
In the snow stopper 16, a concave notch is formed in the center of the vertical plate portion 16 a so as not to interfere with the upper and lower rows of protrusions provided on the bracket 18, and the pair of left and right snow stopper protrusions 17 are connected to the solar cell. The upper end of the bracket 18 holding the front end frame 4 of the panel 3a is projected upward.

  As described above, in the solar panel group 3, the snow stoppers 1, 16 are provided at the gap S between the solar panel 3a, 3b adjacent in the flow direction Y of the roof R, or at the front end of the solar panel 3a located at the eaves. Is fixed so that the snow stopper pieces 11, 11a, 17 are projected upward from the upper surfaces of the solar cell panels 3, 3a, thereby preventing snow from falling on the upper surfaces of the solar cell panels 3, 3a.
