Description

The present invention relates to eaves installed on the wall surface of a building or the like.

The eaves have a rain shelter function in addition to a sunshade function. Those whose main purpose is to block the sunlight are generally called "sunshades", but here, they are collectively referred to as "eaves" including "sunshades". As shown in FIG. 13, the eaves are installed so that the eaves plate 101 projects from the wall surface 9 of the building. A holder 102 is fixed to the wall surface 9 of the building by a plurality of bolts, and the rear end portion of the eaves plate 101 is held by the holder 102 over the entire length (see, for example, Patent Document 1). FIG. 13 shows a state in which most of the sunlight s toward the opening 90 such as a window is blocked by the eaves plate 101. In the figure, the part represented by halftone dots is a shadow area.

In the conventional eaves, the protrusion width, the height and inclination of the eaves plate 101 are determined for each place where the eaves are installed, for example, so that the blocking state of the summer sunlight s is optimized. In the following description, the dimension of the eaves plate 101 in the front-rear direction is referred to as "protruding width", and the dimension in the left-right direction is referred to as "length".

Japanese Patent No. 38546226

The eaves described in Patent Document 1 have a structure in which a holder 102 having a length substantially matching that of the eaves plate 101 is attached to a wall surface 9 of a building, and the rear end portion of the eaves plate 101 is held by the holder 102 over the entire length. is there. For this reason, the structure of the holder 102 becomes complicated, and it takes time and effort to manufacture the eaves and install the eaves on the wall surface 9, resulting in high cost.

Further, in the conventional eaves, when a strong wind blows on the eaves plate 101 from above or below, the wind pressure acting on the eaves plate 101 is large, the holder 102 cannot withstand the wind pressure and is damaged, and the eaves plate 101 may fall off.

In this embodiment, the inclination θ of the eaves plate 2 is adjusted to the optimum value according to the installation location of the eaves, and then the eaves plate 2 is fixed and localized by the connecting shaft 6 described later in the inclined state.

As shown in FIGS. 7 and 8, the connecting metal fitting 50 in this embodiment is attached to the mounting plate 53 to which the protruding wall portion 52 described later is vertically mounted on the back surface of the eaves plate 2 and the tip portion of the arm 3. The connecting member 54 is included. The mounting plate 53 includes a substrate portion 51 fixed to the back surface of the eaves plate 2 by four bolts 56 and nuts 57, and a pair of protruding wall portions 52 and 52 that are integrally formed on the substrate portion 51 and are parallel to each other. It is equipped with. The ring portion 55 of the connecting member 54 is inserted between the protruding wall portions 52.52, and the connecting member 54 and the protruding wall portion 52 are connected and fixed by the connecting shaft 6.

The connecting member 54 integrally has a ring portion 55 through which the connecting shaft 6 is passed at one end and a screw shaft portion 58 at the other end. The thickness of the ring portion 55 is slightly smaller than the gap between the protrusions 52 and 52 of the mounting plate 53, and the ring portion 55 can be inserted between the protrusions 52 and 52. In this embodiment, a commercially available metal fitting called a "denden bolt" is used as the connecting member 54, but the present invention is not limited to this, and a dedicated metal fitting may be manufactured and used. The screw shaft portion 58 of the connecting member 54 is screwed into a screw hole formed in the tubular portion 30 of the arm 3. Holes (not shown) for passing the connecting shaft 6 are provided in the protruding wall portions 52 and 52 of the mounting plate 53, respectively. In this embodiment, the bolt 60 is used as the connecting shaft 6, and the nut 61 is screwed into and tightened by screwing the nut 61 into the hole of the ring portion 55 of the connecting member 54 and the hole of each protruding wall portion 52 to tighten the mounting plate. The facing protruding wall portions 52, 52 of 53 are slightly deformed to sandwich the ring portion 55 of the connecting member 54, whereby the connecting member 54 and the mounting plate 53 are integrally connected and fixed. As the mounting plate 53 of the connecting metal fitting 50, an L-shaped metal fitting may be used instead of the above embodiment.

Further, the connecting tool 5 is not limited to the connecting metal fitting 50 having a structure capable of adjusting the inclination as shown in the illustrated example, and the eaves plate 2 is directly connected and fixed to the tip end portion of the arm 3 at a constant inclination. For example, it may be a screw or a bolt.

In the above-described embodiment, as the fixing tool 4, instead of the anchor bolt 49, the fixing metal fitting 40 having the same configuration as the connecting metal fitting 50 can be used. 9 and 10 show an embodiment using the fixing bracket 40.

The illustrated fixing bracket 40 includes a mounting plate 43 that is mounted on the wall surface 9 of the building with the protruding wall portion 42 sideways, and a connecting member 44 that is mounted on the base end portion of the arm 3. The mounting plate 43 includes a substrate portion 41 fixed to the wall surface 9 by four bolts 46, and a pair of protruding wall portions 42, 42 that are integrally formed on the substrate portion 41 and are parallel to each other. .. A ring portion (not shown) of the connecting member 44 is inserted between the protruding wall portions 42 and 42, and the connecting member 44 is connected and fixed to the protruding wall portion 42 by a connecting shaft 45.

The connecting member 44 has the ring portion through which the connecting shaft 45 is passed at one end, and the screw shaft portion 48 at the other end. The thickness of the ring portion is slightly smaller than the gap between the protruding wall portions 42 and 42 of the mounting plate 43, and the ring portion can be inserted between the protruding wall portions 42 and 42. The screw shaft portion 48 of the connecting member 44 is screwed into a screw hole formed in the tubular portion 3 of the arm 3. Holes (not shown) for passing the connecting shaft 45 are provided in the protruding wall portions 42, 42 of the mounting plate 43, respectively. In the illustrated example, a bolt is used as the connecting shaft 45, and the protruding wall portion of the mounting plate 43 is tightened by screwing a nut into the hole of the ring portion of the connecting member 44 and the bolt passed through the hole of each protruding wall portion 42. The connecting member 44 is sandwiched between the 42 and 42.

In the fixing bracket 40 of this embodiment, the arm 3 is fixed perpendicularly to the wall surface 9 depending on the installation location of the eaves, and as shown in FIGS. 9 and 10, the arm 3 is either left or right. It is possible to shake it in the direction of and fix it. When the arm 3 is fixed and localized by the connecting shaft 45 in a state where the arm 3 is swung, the connecting metal fitting 50 also attaches the mounting plate 53 to the back surface of the eaves plate 2 with the protruding wall portion 52 turned sideways. As a result, as shown in FIG. 9, the swing of the arm 3 in the left-right direction can be adjusted.

In order to install the eaves 1 on the wall surface 9 of the building, the components of the eaves 1, that is, the eaves plate 2, the arm 3, the fixture 4, and the connector 5 are brought into the installation site of the eaves 1. First, the base end portion of the arm 3 is fixed to the wall surface 9 of the building by the fixture 4, and then the eaves plate 2 is connected to the tip end portion of the arm 3 by the connector 5. When the eaves plate 2 is attached, the inclination θ of the eaves plate 2 is adjusted to connect and fix the eaves plate 2, and the eaves plate 2 is localized at the tip of the arm 3 in a posture capable of blocking sunlight.

In the installation configuration of FIG. 1, the eaves plate 2 is localized with the front surface of the eaves plate 2 facing diagonally upward, whereby most of the sunlight s toward the opening 90 of the building is blocked by the eaves plate 2. ing. As in this installation example, it is not always necessary to assemble all the components of the eaves at the installation site of the eaves. For example, in a factory, the eaves plate 2 is connected and fixed in advance to the tip of the arm 3 by a connecting tool 5. You may.

FIG. 11 shows another installation form in which the eaves plate 2 is localized with the front surface of the eaves plate 2 facing diagonally downward, whereby about half of the sunlight s toward the opening 90 of the building is provided. It is blocked by the eaves plate 2.

FIG. 12 shows yet another installation mode, in which the eaves plate 2 is localized with the front surface of the eaves plate 2 facing the front, whereby a part of the sunlight s toward the opening 90 of the building is provided. It is blocked by the eaves plate 2.

In any of the installation forms, all or part of the sunlight s toward the opening 90 of the building is blocked by the eaves plate 2, and the effect of awning can be obtained. Since the eaves plate 2 is separated from the wall surface 9 of the building, the wind can pass through the gap between the eaves plate 2 and the wall surface 9, so that a large wind pressure does not act on the eaves plate 2 and the eaves plate 2 is an arm. There is no risk of falling off from 3, and eaves can be installed even in windy regions.
Further, in the installation form of FIG. 12, since the eaves plate 2 is oriented vertically, there is no risk of snow accumulation on the eaves plate 2, and the eaves can be installed even in a region with a lot of snow. It should be noted that the effect of preventing snow accumulation can be enhanced by forming the end face of the eaves plate 2 facing upward into a thin shape first, or by making the arm 3 a plate-like body and making the upper end face a thin shape first. Further, the eaves plate 2 does not necessarily have to be in the vertical orientation shown in FIG. 12, and for example, if the eaves plate 2 is in an inclined posture close to the vertical orientation as shown in FIGS. Is.

In either aspect, since the eaves plate 2 is separated from the wall surface 9 of the building, raindrops pass through the gap between the eaves plate 2 and the wall surface 9, and the effect of rain protection is lacking. As shown, the effect of rain protection can be added by horizontally supporting the strip-shaped second eaves plate 7 whose protrusion width is smaller than the length of the arm 3 by the two arms 3 and 3. In this case, since the wind passes through the gap between the eaves plate 2 and the second eaves plate 7, a large wind pressure does not act on the eaves plate 2. In addition to the extruded aluminum profile, a synthetic resin plate or the like can be used for the second eaves plate 7, and both ends thereof are fixed to the arm 3 by a method such as screwing.
