Description

The present invention relates to a simple structure that can be installed in a residential garden, etc.

Traditionally, decks have been installed in residential gardens. However, there are cases where a rainwater catch basin or handhole is already installed where the deck is to be installed, and even if these are not installed, there are cases where lighting or other equipment is to be installed on the deck. In light of these various situations and demands, when handholes are already installed, easy access to the equipment is required, and when lighting or other equipment is installed, electrical wiring must be run on the underside of the deck and subsequent maintenance of the equipment must be possible. For these reasons, there has been a demand for a structure that allows for maintenance of the space under the deck.

In view of the above-mentioned circumstances, the present invention aims to provide a deck that allows maintenance of the space under the deck material.

The present invention solves the above-mentioned problems by providing a simple structure which comprises a deck material, an inspection door, and an inspection door support material, the inspection door support material being attached to the side of a member which supports the deck material, and which is characterized in that the part facing the gap formed between the deck material and the inspection door is a recess which opens upward.

The inspection door allows for maintenance of the space under the deck material. The inspection door support material also has a recess that opens upward at the location facing the gap formed between the deck material and the inspection door, and this recess is a drainage recess, allowing for good drainage.

(Example)
The following description will be given using drawings, but the drawings are created for explanatory purposes, and in order to make the description easier to understand, some components not necessary for the description may not be shown intentionally. In addition, some components may be shown intentionally large or small for the purpose of explanation, and the drawings are not drawn to an accurate scale. In the following description, the same reference numerals in different drawings indicate parts with the same function, and duplicate descriptions in each drawing will be omitted as appropriate.

Below, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 8 show an embodiment of the simple structure according to the present invention, applied to a deck installed in the garden of a house. As shown in Figure 1, when the opposite side of the house is defined as the front and the left and right are defined as viewed from the front, this deck is installed with the rear edge along the exterior wall of the building, allowing people to step onto the deck from the terrace window of the building. This deck is constructed by hanging multiple joists 3 at intervals in the front and back on top of supports 2 erected on the front, back, left and right, and multiple deck materials 4 are hung on the joists 3 in a row in the left and right direction, facing in the front and back direction.

Figure 2 is an enlarged view of the deck, excluding the residential area of Figure 1. An inspection hatch 1 is provided on the left side of the deck, and an inspection door 11 is fitted into the inspection hatch 1. Figure 3 shows the state of Figure 2 with the inspection door 11 removed. From Figure 3, it can be seen that the inspection door 11 is supported on an inspection door support material 12.

An end cap 41 is fitted to the end of each deck material 4. The deck material 4 is a synthetic wood made by extruding synthetic resin mixed with wood powder, and the end cap 41 is also a synthetic wood made by extrusion molding or the like. As shown in Figures 2 and 3, the end cap 41 is prepared with a height greater than that of the deck material 4, and is attached by adjusting the top end of the end cap 41 so that it is flush with the top end of the deck material 4.

4 is a perspective view of the inspection door 11. As with the deck material 4 used in the main body of the deck, synthetic wood extruded from synthetic resin mixed with wood powder is used for the inspection door 11. An inspection hatch joist 111 is attached to the underside of the inspection door 11. A handle 13 is provided on the upper surface of the inspection door 11, approximately in the center of the front-to-rear position of the inspection door 11, on the right hand side of the deck in the left-right direction defined above. The handle 13 can be rotated 180 degrees so that the handle side faces upward.

Figure 5 is an enlarged perspective view of a portion of the deck with the inspection door 11 removed and the inspection hatch 1 open. As shown in Figure 5, inspection door support members 12 are provided at the front and rear of the inspection hatch 1, protruding from the deck material 4 so as to support the inspection door 11. The inspection door support member 12 is a shaped member having a recess 123 that opens upward. The recess 123 functions as a drain. The two arrows in Figure 5 indicate the direction in which rainwater, etc. will flow.

Figure 6 is a side cross-sectional view taken along line A-A in Figure 2. As shown in Figure 6, the joists 3 are made of hollow aluminum shaped members with a generally convex cross section, and have a pair of fins 31 on their underside along the longitudinal direction. The posts 2 are made of aluminum shaped members with a generally square cross section, and as shown in Figure 1, their upper ends are inserted between the pair of fins 31 of the joists 3 and fixed with screws. The lower ends of the multiple posts 2 are fixed with metal fittings to foundation stones buried in the ground, as shown in Figure 6.

(Inspection hatch structure)
As shown in FIG. 6, the inspection hatch 1 is an opening formed by cutting a part of the deck material 4 that is bridged between adjacent joists 3. An inspection door support material 12, which is a metal fitting having an approximately L-shaped angle, is fixed from the side rising part of the joists 3 on both sides where the inspection hatch 1 is arranged to the opening beyond the deck material 4. The vertical part 121 of the inspection door support material 12 is fixed to the side of the joists 3 with bolts and nuts. The horizontal part 122 of the inspection door support material 12 is fixed to the lower surface of the deck material 4 with screws to prevent the deck material 4 from bending. The inspection door support material 12 protruding from the opening supports the lower edge part that contacts the front and rear side surfaces of the inspection door 11. The inspection door 11 is the same material as the deck material 4, but is cut and adjusted to a size according to the opening, and is one size smaller than the size of the opening.
A door protective part 14 is provided on the upper edge part in contact with the front and rear side surfaces of the inspection door 11 to prevent damage due to contact with the edge on the opening side of the deck material 4 when the inspection door 11 is opened or closed. Similarly, an opening side protective part 42 is provided on the edge on the opening side of the deck material 4. Specifically, the door protective part 14 and the opening side protective part 42 are edge materials made of painted aluminum profiles.

As can be seen from FIG. 6, the inspection door support material 12 is a shaped material having a recess 123 opening upward at a location facing the gap formed between the deck material 4 and the inspection door 11. The reason for using such a shaped material is that if the inspection door support material 12 has a flat shape, rainwater, etc. that has entered the gap will have no way to escape and will remain there, so there is a risk that the deck material 4 will be damaged if it is in contact with the remaining water for a long period of time, or the inspection door support material 12 will be corroded, and this is to prevent this. Rainwater, etc. that has entered the gap quickly flows down from both the left and right ends of the inspection door support material 12 and does not remain there. The shape of the recess in this embodiment is an inverted trapezoid, but it may be an R-shaped one or an inverted triangle, and any shape may be used as long as it is a shape that can drain rainwater, etc. without retaining it.
In addition, since the recess 123 of the inspection door support member 12 also serves as a drain, there is no need to provide a separate drainage means.

As shown in Figure 6, the handle 13 is located approximately in the center of the front-to-rear position of the inspection door 11, and is also approximately in the center in the left-right position, located on the right side of the main deck in the left-right direction defined above. The handle 13 can be rotated 180 degrees about the axis 131 so that the handle side faces upward. Figure 7 shows the handle 13 in a raised state. By raising the handle 13, it is possible to grasp it and lift up the inspection door 11 to remove it.

Figure 8 shows the state with the inspection door 11 removed. The opening 5 is large enough to inspect the space below the deck material 4, and from here it is possible to access the rainwater manhole (not shown) located below the deck material 4, and to perform maintenance on electrical components and wiring (not shown) arranged in the space below the deck material 4.

As described above, the simplified structure according to the embodiment of the present invention allows inspection of the space below the deck material 4 and maintenance of the equipment disposed in the space below. Furthermore, the inspection door support material 12 has a recess that opens upward at the location facing the gap formed between the deck material 4 and the inspection door 11, and since this recess is a drainage recess, rainwater, etc. that has entered the gap flows quickly down from both the left and right ends of the inspection door support material 12 and does not stagnate. Therefore, there is no risk of the deck material 4 being damaged or the inspection door support material 12 being corroded.

The above describes the simplified structure of the embodiment of the present invention in detail with reference to the drawings, and the structure thereof has been described, but the specific configuration is not limited to these embodiments, and the present invention includes design changes within the scope of the present invention. For example, the inspection door support material 12 is not an L-shaped angle fixed to the slats 3, and as long as the inspection door support material 12 is robust due to its material and size, and can obtain sufficient support only by fixing it to the underside of the deck material 4, the inspection door support material 12 does not have to be an L-shaped angle fixed to the slats 3, and can be a straight-shaped material fixed only to the underside of the deck material 4, as long as there is a recess in the middle that performs a drainage function. In addition, the position where the inspection hatch 1 is provided does not have to be between the frontmost slats 3 and the second slats 3, but may be between the second slats 3 and the third slats 3. Furthermore, the material of the deck material 4 may be natural wood instead of synthetic wood, or other molded products.

Furthermore, the above-mentioned embodiments can be combined by reusing each other's technologies, so long as there are no particular contradictions or problems in their purpose and configuration, etc.
