The second arm portion 49 protrudes in a substantially horizontal direction from the substantially center outside of the inclined plate 41, and an engagement protrusion 51 is formed at the tip. The other end engaging portion 50 is provided at the other end of the inclined plate 41, and includes an engaging groove 52 that opens outward and a seat surface 53 that protrudes inward.

  In the vertical plate 40 and the inclined plate 41 configured as described above, the first arm portion 43 and the first plate 43 and the first plate 43 are formed by inserting one end engaging portions 48 into the bent portions 42 and engaging the engaging projections 51 with the engagement receivers 45. The two arms 49 are connected together to be integrated.

  Next, the effect of this embodiment comprised as mentioned above is demonstrated. First, the first member 5a composed of the first top plate portion 14A and the outer side plate portion 15 and the second member 5b composed of the second top plate portion 14B and the inner side plate portion 15 are integrally formed.

  Next, the fitting grooves 24 formed in the rising walls 21A and 21B of the brackets 4A and 4B and the fitting protrusions 25 are fitted to connect the brackets 4A and 4B integrally. Then, the reinforcing plate 11 is passed through the insertion holes 19 formed in the rising walls 21A, 21B of the brackets 4A, 4B and the two receiving ribs 9, and the brackets 4A, 4B are linearly positioned by the reinforcing plate 11. Thereafter, a bolt 14 is inserted into the long holes 12 and 12 formed in the reinforcing plate 11 and the brackets 4A and 4B, and the bolt 14 is screwed into the top end portion 3 of the parapet 2 to reinforce the reinforcing plate 11 and the brackets 4A and 4B. Fasten together. As a result, the divided brackets 4A and 4B are connected and fixed integrally in a straight line while maintaining the level, and the brackets 4A and 4B are integrated to prevent deformation.

  Next, the first member 5a is covered with the bracket 4A. At this time, the side plate portion 15 of the first member 5a is elastically deformed so as to open inward, the first member 5a is lowered, and the protruding portion 29 formed on the first top plate portion 14 is formed on the first bracket 4A. After engaging the receiving portion 26, the side plate portion 15 is elastically restored and the flange portion 18 formed at the front end of the side plate portion 15 is locked to the front end side of the hanging wall portion 7 of each bracket 4A, and the bracket 4A is One member 5a is fixed.

  Next, the snowfall prevention member 1 is attached to the first member 5a. At this time, after engaging the other end engaging portion 50 of the inclined plate 41 with the inner end edge of the first top plate portion 14A, the vertical plate 40 is opened inward to be elastically deformed, and the upper holding portion 46 is moved to the side plate. The lower pinching portion 47 is engaged with the flange portion 18 to fix the snow leopard prevention member 1 to the first member 5a.

  Next, the second member 5b is fixed to the bracket 4B. At this time, after the outer end portion of the second top plate portion 14B is brought into contact with the inner end of the inclined plate 41, the first engaging portion 34 is locked to the support portion 32 formed at the center portion of the flat portion 30. When the side plate portion 15 is elastically deformed so as to open inward and the inner end of the second member 5b is lowered and leveled, the space between the first hook portion 34 and the second hook portion 35 on the back surface of the top plate portion 14B is increased. The inner wall of the second hooking portion 35 that is supported by the support portion 32 and hangs down contacts the outer wall of the rising portion 31, and the first member 5a and the second member 5b are integrally engaged. At this time, the seat surface formed in the other end engaging portion comes into contact with the upper surface of the outer end portion of the second top plate portion 14B. As a result, in the snowfall prevention member 1, when a downward load is applied to the inclined plate 41, such as when the wind blows from the outside to the inside, only an external force is transmitted from the engagement groove 52 to the first top plate portion 14A. Since the external force can be transmitted from the seat surface 53 to the second top plate portion 14B, it can be more stably fixed to the headboard 5.

  Thus, after engaging the other end engaging portion 50 opened to the outside with the inner end edge of the first top plate portion 14A, the outer end portion of the second top plate portion 14B is engaged with the other end of the inclined plate 41. The second top plate portion 14B is fixed to the bracket 4B by contacting the inner end of the joint portion 50. As a result, the outer end of the second top plate portion 14B presses the inner end of the other end engaging portion 50 of the inclined plate 41 engaged with the inner end edge of the first top plate portion 14A outward. Therefore, in the snow leopard prevention member 1 according to the present embodiment, the outer end portion of the second top plate portion 14B is located outside the other end engaging portion 50 of the inclined plate 41, that is, without using bolts as in the prior art. By pressing against the inner edge of the first top plate portion 14A, it is possible to reliably prevent the inclined plate from coming off.

  Further, the second member 5b fixes the second member 5b to the bracket 4B by locking the flange portion 18 formed at the tip of the side plate portion 15 to the tip side of the hanging wall portion 7 of the bracket 4B. Then, the back surface of the first top plate portion 14A is in contact with the outer receiving rib 9, the inner receiving rib 9 is in contact with the back surface of the second top plate portion 14B, and the flat portion 30 and the flat receiving portion 22 are in contact with each other. Three portions of the portion 14 are supported from the back surface.

  In this way, the snow candy preventing member 1 is fixed to the headboard 5. In this case, since the snow leopard preventing member 1 is fixed to the headboard 5 by the other end engaging portion 50 and the holding means 44, the work man-hour can be reduced as compared with the case where it is fixed by bolts as in the prior art. Because it can, it can be fixed easily.

  Further, the headboard 5 includes the first member 5a and the second member 5b, and the outer end of the second top plate portion 14B is brought into contact with the inner end of the inclined plate 41. The end engaging portion 50 can be prevented from coming off, and the mounting strength can be ensured.

  Therefore, even when an external force is applied to the top plate part 14 due to falling objects, wind pressure, rainfall, etc. after the headboard 5 is attached, the degree of bending or dent is further reduced, and the aesthetics are impaired over a long period of time. In addition, it is possible to prevent rainwater from accumulating in the bent or recessed portions and causing the water to get stuck on the futon when the futon is dried on the balustrade. In addition, there is a low possibility that a crack is generated from the bent portion or the recessed portion, rainwater or the like is accumulated between the headboard 5 and the parapet 2 and the inside of the headboard 5 is corroded. Further, although the manufacturing cost of the mold increases more than proportional to the size, according to the present embodiment, although two molds are required, the size is about half that of the case where the headboard 5 is integrally formed. Therefore, the cost for manufacturing the mold can be reduced.

Note that the attachment of the first member 5a and the second member 5b is not limited to the above-described method, and the snowfall prevention member 1 is fixed to the first member 5a and the second member 5b in advance, and then the brackets 4A and 4B are attached. It is good also as attaching.
