Description

  The present invention relates to a base cabinet including a piping inspection port cover that covers a piping inspection port that opens to the back side of a bottom plate, and a piping inspection port cover.

  The sink cabinet or gas cabinet installed in the kitchen includes a base cabinet that supports the top plate below the top plate on which the sink or gas range is provided. The base cabinet has a rectangular parallelepiped shape including a wooden bottom plate, a back plate, and left and right side plates, and a top plate is placed and fixed on the top. Some of these base cabinets are provided with a door on the front, and some are provided with a drawer to be taken in and out from the front.

  FIG. 10 is a side sectional view showing a configuration of a conventional base cabinet, and shows a lower corner of the innermost part of the base cabinet. The base cabinet is provided with pipes such as gas pipes and water pipes (not shown), and a pipe inspection port 111 for inspecting the pipes that are piped opens to the back side of the bottom plate 11. On the outer surface of the back plate 12, horizontal rails 141 and 142 that reinforce the middle and the bottom of the back plate 12 are fixed. Such a base cabinet is installed on the floor surface F such that the horizontal rails 141 and 142 are in contact with the wall surface W.

  In order to cover the piping inspection port 111, conventionally, a flat plate inspection port cover 4 having an insertion hole 4a through which a pipe (not shown) piped from the outside of the base cabinet to the top plate side is inserted. It was used.

  When securing a piping space inside the base cabinet (for example, a piping space for a pipe that is horizontally routed at a position higher than the height of the bottom plate 11 or a piping space for a large-diameter pipe that rises from the floor F to the position), A substantially rectangular support plate 42 that supports the pipe inspection port cover 4 is erected substantially parallel to the back plate 12 on the upper surface of the bottom plate 11 before the pipe inspection port 111, and is formed on the side end surface of the support plate 42. 422 is fitted into recesses formed on the inner surfaces of both side plates (not shown). A support fitting 410 that supports the pipe inspection port cover 4 is fastened to the back plate 12 and the horizontal rail 141 with screws 411 at substantially the same height as the support plate 42 on the inner surface of the back plate 12.

  An engaging portion 41 that engages with the support fitting 410 is formed at one end (near one end) of the pipe inspection port cover 4. The operator holds, for example, an appropriate position of the pipe inspection port cover 4 by hand, engages the engaging portion 41 with the support fitting 410, and supports the other end (near the other terminal) facing the one end. The pipe inspection port 111 is closed by mounting on the front end surface of the plate 42 and screwing the other end to the support plate 42 with screws 421. Conversely, when opening the pipe inspection port 111, the operator removes the screw 421, holds the appropriate position of the pipe inspection port cover 4 by hand, and engages the engagement portion 41 with the support fitting 410. Is released and the piping inspection port cover 4 is removed.

If the piping space is not secured inside the base cabinet, the other end of the piping inspection port cover 4 may be screwed to the bottom plate 11 with screws 421. The support metal fitting 410 needs to be screwed to the back plate 12 and the horizontal rail 142 with screws 411 at substantially the same height as the bottom plate 11 on the inner surface of the plate 12. In addition, in this case, there is no need to form a concave portion in the side plate for fitting with the convex portion 422 of the support plate 42, so that the side plate is different depending on whether or not a piping space is secured inside the base cabinet. It was necessary to prepare.

  That is, when the pipe inspection port cover 4 is used, there is a problem in that the material cost of the support plate 42, the support metal fitting 410 and the screw 411, attachment work, and the like are required, and the side plates cannot be shared.

  FIG. 11 is a side sectional view showing another configuration of the conventional base cabinet, and shows a lower corner of the innermost part of the base cabinet. In order to solve the above-described problem, it has been proposed to use a pipe inspection port cover 5 having an L-shape in side view having a first plate portion 51 and a second plate portion 52 that are substantially orthogonal to each other (Patent Literature). 1-4).

  The pipe inspection port cover 5 is substantially perpendicular to both the first plate portion 51 and the second plate portion 52 at both ends (near both ends) substantially parallel to the intersection of the first plate portion 51 and the second plate portion 52, respectively. Are provided with plate-like screw allowances 510 and 520 that rise to the outside of the L-shape.

  When securing the piping space inside the base cabinet, the operator holds, for example, an appropriate position of the piping inspection port cover 5 by hand, and the L-shape of the first plate portion 51 in which the insertion hole 51a is formed. The inner surface is directed downward, the L-shaped inner surface of the second plate portion 52 is directed in an inverted L shape, and the back surface of the screw fastening allowance 510 is brought into contact with the back plate 12, The lower surface of the fastening allowance 520 is placed on the bottom plate 11. The operator closes the pipe inspection port 111 by screwing the screw fastening allowance 510 to the back plate 12 and the horizontal rail 141 with the screw 511 and screwing the screw fastening allowance 520 to the bottom plate 11 with the screw 521. Conversely, when opening the piping inspection port 111, the operator removes the piping inspection port cover 5 by removing the screws 511 and 521, holding the appropriate position of the piping inspection port cover 5 by hand.

  When the piping space is not secured inside the base cabinet, the operator uses, for example, an L-shaped piping inspection port cover having a first plate portion and a second plate portion that do not have screw fastening allowances, and checks the piping. Holding the appropriate position of the mouth cover by hand, the L-shaped outer surface of the first plate part is directed downward, and the L-shaped outer surface of the second plate part is directed erect L The upper end (near the upper terminal) and the lower end (near the lower terminal) are screwed to the back plate 12, the cross rail 141, and the bottom plate 11, respectively (Patent Documents 1 and 3).

By using the pipe inspection port cover as described above, the support plate 42, the support fitting 410, and the screw 411 are unnecessary, and the side plate includes a base cabinet that secures a piping space inside and a base cabinet that does not secure a piping space inside. Can be shared.

An embodiment to which 3 is applied will be described.

  In this base cabinet, a support plate 15 is erected in order to secure a piping space for the water pipe 101 on the lower back side of the bottom plate 11, and the bottom plate 11 is located above the upper end surface of the support plate 15 and on the top surface of the bottom plate 11. And the heights of the upper end surfaces of the lower back plates 121 and 122 are substantially equal. However, the length in the front-rear direction of the bottom plate 11 is longer than the length in the front-rear direction of the bottom plate 11 of the base cabinet of the third embodiment, and therefore the depth of the pipe inspection port 111 is reduced. The length in the front-rear direction from the back end surface to the front surface of the upper back plate 124 is substantially equal to the length from the front surface of the vertical plate portion 31 to the back surface of the reinforcing plate portion 321. Further, the standing position of the support plate 15 is a position on the near side from the position of the back end surface of the bottom plate 11 by the protruding length from the vertical plate portion 31 of the reinforcing plate portion 311.

  The operator places the pipe inspection port cover 3 in an inverted L shape in a side view, with the inner surface of the vertical plate portion 31 facing the back side and the inner surface of the horizontal plate portion 32 facing the lower side. In addition, the operator places the upper end side of the pipe inspection port cover 3 on the upper end surfaces of the lower back plates 121 and 122, and places the lower end side on the floor surface F below the pipe inspection port 111. The piping inspection port 111 is covered with the horizontal plate portion 32 of the piping inspection port cover 3.

  More specifically, the operator places the pipe inspection port cover 3 above the piping inspection port 111 by placing a hand on the upper handle portion 322 and flexes the vertical plate portion 31 to the back side to reinforce. The plate portion 311 and the handle portion 312 are arranged below the bottom lower surface of the bottom plate 11. Next, the operator brings the back surface of the reinforcing plate portion 321 into contact with the front surface of the upper back plate 124, lowers the piping inspection port cover 3 directly below, and lowers the lower surface of the upper end portion of the piping inspection port cover 3, that is, the inner surface of the horizontal plate portion 32. The rear terminal side is placed on the upper end surfaces of the lower back plates 121 and 122, and the lower surface of the handle portion main body 312b on the lower end side is placed on the floor surface F while the front surface of the vertical plate portion 31 is in contact with the rear end surface of the bottom plate 11. Placed on. At this time, the upper surface of the horizontal plate portion 32 and the upper surface of the bottom plate 11 are located on the same plane.

  Here, the operator does not perform screwing on the lower back plates 121 and 122 and the floor surface F of each of the horizontal plate portion 32 and the handle portion 312, or engagement with the support metal fittings. For this reason, the piping inspection port cover 3 is freely removable from the lower back plates 121 and 122 and the floor surface F. However, also in this case, the pipe inspection port cover 3 covering the pipe inspection port 111 does not rattle from front to back and left and right, and the horizontal plate portion 32 or the handle portion 312 falls off the lower back plates 121 and 122 or the floor surface F. There is nothing.

  When removing the piping inspection port cover 3 from the piping inspection port 111, the operator lifts the piping inspection port cover 3 by placing a hand on the handle portion 322, and from the piping inspection port 111, the vertical plate portion 31, the reinforcing plate portion 311 and the handle. The piping inspection port cover 3 is removed from the piping inspection port 111 by extracting the part 312.
