  Therefore, it is possible to set so that the snow 3 is surely slid and guided from the panel side end portion 7 to the upper surface of the solar panel 2 for any solar panel installation roof.

  Specific embodiments of the present invention will be described with reference to the drawings.

  The solar panel-mounted roof snowplow of this embodiment is provided with a guide plate portion 5 for guiding and guiding the snow 3 that slides down on the roof 1 on the main body 4 fixed to the roof 1.

  Specifically, the main body 4 of the present embodiment is configured by a pair of left and right stand frames 12 and a connecting frame 13 that connects the pair of stand frames 12.

  As shown in FIGS. 1 and 2, the stand frame 12 is arranged on the front end (the eave side of the roof 1 (downward side of the roof slope)) of the bottom frame portion 14 where the metal strip is bent and placed on the upper surface of the roof 1. The vertical frame portion 15 rises at a right angle from the edge of the vertical frame, and the rear end of the bottom frame portion 14 (the end portion disposed on the ridge side of the roof 1 (the roof gradient upper side)) and the upper end of the vertical frame portion 15 It is configured as a substantially right-angled isosceles triangular frame in a side view with the oblique frame portion 16 in between.

  The stand frame 12 has a configuration in which the rear end of the bottom frame portion 14 and the rear end of the oblique frame portion 16 are overlapped and held in a triangular frame shape, and each of the left and right stand frames 12 is further configured. Both ends of the connecting frame 13 adopting a metal strip having a predetermined length are attached (overlay stop) on the overlap stop portion to constitute the main body 4 having a substantially U shape in plan view. Reference numeral 22 in the figure is a fastening tool (rivet) for fastening the connecting frame 13 to the stand frame 12 in an overlapping manner.

  In the present embodiment, the main body 4 configured in this manner is placed on the peripheral edge of the solar panel 2 on the roof gradient upper side where each of the standing frame portions 15 is installed on the roof 1 as shown in FIGS. It is set as the structure fixed on the roof 1 of the roof gradient upper side rather than the solar panel 2 so that it may be erected. 3 and 4, a known fixing bracket 17 referred to as an S-shaped foot plate is projected from the rear portion (end portion arranged on the ridge side) of the main body 4, and the main body 4 is interposed via the fixing bracket 17. However, the roof 1 to be fixed and the fixing means to the roof 1 are not limited to this, and the design can be changed as appropriate. Reference numeral 23 in the figure denotes a mounting bracket for mounting and installing the solar panel 2 on the roof 1, and FIGS. 3 and 4 show a case where a large number of solar panels 2 are placed flat via the mounting bracket 23. .

  In the present embodiment, the guide plate portion 5 made of a thin metal plate in the form of a horizontal rectangular plate is provided between the left and right oblique frame portions 16 of the main body 4 in a erected state.

  That is, the guide plate portion 5 is formed in the tilt guide plate portion 5 that is inclined toward the roof slope lower side (eave side) with respect to the upper surface of the roof 1 on which the bottom frame portion 14 is placed. The inclined lower end of the portion 5 is the roof side end 6 that is close to or abuts the upper surface of the roof 1, and the inclined upper end of the inclined guide plate portion 5 is adjacent to the upper surface of the solar panel 2 or As the said panel side edge part 7 which contact | abuts, it is set as the structure arrange | positioned between the upper surface of the solar panel 2, and the roof 1 upper surface of the roof gradient upper side from the solar panel 2. FIG.

  Further, the guide plate portion 5 of the present embodiment is provided with a projecting and retracting mechanism portion 8 capable of adjusting the projecting length of the panel side end portion 7 according to the installation height of the solar panel 2 with respect to the upper surface of the roof 1. .

  Specifically, the guide plate portion 5 includes a base plate 10 fixed to the oblique frame portion 16 of the main body 4 and a slide plate 11 which is a separate component from the base plate 10, and the projecting and retracting mechanism is provided. The portion 8 is configured such that the slide plate 11 is provided so as to be able to move in a superimposed manner in the protruding and retracting direction with respect to the base plate 10.

  More specifically, the base plate 10 has a front-rear width (width in the gradient direction of the roof 1) set to a width dimension substantially equal to the frame length width of the oblique frame portion 16, and the left-right width is set to the left and right stand frames. The width dimension is set to be approximately the same as the interval width dimension between 12, and screw holes 18 are formed through the four corners.

  In addition, the slide plate 11 has a front-rear width that is slightly narrower than the front-rear width of the base plate 10 and a left-right width that is the same as that of the base plate 10, and further, the front-rear width is set to the left and right side edges respectively. A guide slot 19 having a length in the direction is formed to penetrate therethrough.

  The guide plate 5 (base plate 10 and slide plate 11) is attached to the oblique frame portion 16 at both end positions of the oblique frame portion 16 corresponding to the screw holes 18 at the four corners of the base plate 10. The base plate 10 is attached to the oblique frame portion 16 by forming the female screw holes 20 and screwing the screws 21 inserted into the screw holes 18 into the female screw holes 20 into the female screw holes 20, respectively. At this time, the slide plate 11 is disposed between the inclined upper side of the oblique frame portion 16 and the inclined upper side of the base plate 10, and the left and right screw holes 18 on the inclined upper side of the base plate 10 The slide plate 11 is attached to the oblique frame portion 16 together with the base plate 10 by communicating with the guide long hole 19 and screwing the screw 21 inserted into the communication hole into the female screw hole 20. .

  Due to the relationship between the guide elongated hole 19 and the screw 21, the projecting / retracting mechanism portion 8 enables the slide plate 11 to project and retract relative to the base plate 10 within the range of movement of the guide elongated hole 19 allowed by the screw 21. Is configured.

  Further, the sliding movement of the slide plate 11 by the projecting and retracting mechanism portion 8 is such that the slide plate 11 can be stopped at an arbitrary position by the frictional resistance between the oblique frame portion 16 sandwiching the slide plate 11 and the base plate 10. The tightening degree of the screw 21 is set and configured.

  Further, in this embodiment, the front end portion of the slide plate 11 is used as the panel side end portion 7, and the guide plate portion 5 and the solar plate are aligned with the panel side end portion 7 along the upper surface or the outer periphery of the solar panel 2. A discharge guide portion 9 that can eliminate a step on the upper surface of the panel 2 is provided.

  Specifically, the protruding tip portion of the slide plate 11 is bent so as to be substantially parallel to the bottom frame portion 14, and this bent tip plate portion is used as the discharge guide portion 9. Then, as shown in FIG. 3, for example, as shown in FIG. 3, the plate-like discharge guide portion 9 can be placed along the upper surface of the solar panel 2 so as to overlap the upper surface of the roof gradient. Although there is a slight step corresponding to the plate thickness of the portion 9, there is almost no step between the slide plate 11 (guidance plate portion 5) and the upper surface of the solar panel 2. Thus, the snow 3 sliding on the guide plate 5 is smoothly slid and discharged to the upper surface of the solar panel 2. In addition, the statement “can eliminate the step between the guide plate portion and the upper surface of the solar panel” in claim 3 completely eliminates the step difference between the upper surface of the guide plate portion 5 and the solar panel 2 (the upper surface of the guide plate portion 5 and the solar panel). This means not only that the upper surface of the panel 2 is flush with the upper surface of the panel 2, but also includes a configuration in which a slight step that does not hinder the sliding of the snow 3 occurs as in this embodiment. It is what.

  As shown in FIGS. 3 and 4, the solar panel-installed roof snow guard of this embodiment configured in this way is fixed on the roof 1 above the roof gradient from the solar panel 2 installed on the roof 1. (Multiple solar panels installed on the ridge side of the solar panels 2 arranged side by side are fixed by arranging a plurality of snow guards for the roof of this solar panel installed on the upper side of the roof slope), and the protruding length of the panel side end 7 is adjusted. Then, when the guide plate portion 5 is disposed between the upper surface of the solar panel 2 and the upper surface of the roof 1 above the solar panel 2, the snow 3 accumulated on the upper roof gradient side from the solar panel 2. When the snow slides down along the upper surface of the roof 1, the snow 3 slides on the guide plate 5 from the roof side end 6 of the guide plate 5 via the connecting frame 13 and slides on the guide plate 5. From the panel side end 7 of the solar panel 2 The snow 3 is prevented from entering below the solar panel 2 (the snow 3 guided to the upper surface of the solar panel 2 slides on the upper surface of the solar panel 2). And slide down to the eaves side (lower roof slope).

  At this time, in this embodiment, a gap corresponding to the thickness of the overlap stop portion of the stand frame 12 is generated between the connecting frame 13 and the upper surface of the roof 1 (the gap below the connecting frame 13 is at the time of rainfall). Therefore, there is a concern that some snow 3 will enter the solar panel 2 below this gap, but the snow 3 entering from this gap will remain in a small amount. There is no problem that the connection cable wired to the cable is disconnected. It should be noted that the description in claim 1 “prevents snow falling from the upper side of the roof slope from the solar panel below the solar panel installed on the roof” means that the snow 3 is below the solar panel 2. The solar panel 2 is not only meant to completely prevent entry, but a small amount of snow 3 (that is, a small amount of snow 3 that does not disconnect the connection cable) as in this embodiment. It is used in the meaning including the structure which may enter below.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
