Description

  The present invention relates to an improvement of a shelf for effectively using a storage space of a cabinet under a sink of a sink or a sink.

  In order to effectively use the storage space in the cabinet for the cabinet under the sink having a vertical pipe such as a drain trap in the storage space under the sink, the applicant of the present application uses pipes or the like in front and rear between the left and right support legs. An assembly-type table shelf has been proposed in which a horizontal frame is fixedly secured, and an appropriate shelf plate provided with flanges at both ends is provided between the front and rear horizontal frames (Patent Document 1).

  According to this storage shelf, by installing shelf boards on the left and right sides of the drain trap, the storage space is divided up and down while limiting the dead space in the cabinet to only before and after the drain trap. Can be improved.

Registered Utility Model No. 3004815

  However, the above conventional shelf has room for improvement in terms of assembly. In other words, the conventional shelf has an installation mode in which the horizontal frames supporting the shelf plates are provided on both the front and rear sides of the support legs, and the drain traps are positioned inside the front and rear horizontal frames. The frame with the frame attached could not be installed in the cabinet afterwards, and at least the horizontal frame that was located behind (the back side of the cabinet) had to be installed inside the cabinet. Therefore, the conventional shelf has the inconvenience that a hand is inserted into the back of a narrow and dark cabinet, and the rear horizontal frame must be attached between the support legs with an unreasonable posture.

  In addition, the conventional shelf has room for improvement in terms of storage efficiency. In other words, as described above, since the horizontal frame is provided on both the front and back of the support leg as described above, the horizontal frame becomes an obstacle to taking in and out the articles before and after the drain trap where the shelf cannot be installed. It was completely dead space. In this respect, even if it is inevitable that the rear side of the drain trap becomes a dead space, the above-described conventional shelf also makes the dead space in front of the drain trap.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a shelf for a cabinet under a sink that can be assembled more easily than before and can reduce a dead space. .

In order to achieve the above-described object, the present invention provides a storage shelf installed in a sink lower cabinet having a vertical pipe such as a drain trap in a storage space under the sink, such as a sink cabinet or a wash basin cabinet. A pair of support legs facing left and right across the first pipe, a first pipe installed between the support legs, and positioned between the first pipe and the vertical pipe and installed between the support legs in parallel with the first pipe. A second pipe, and a shelf that is supported horizontally by one end supported by the first pipe, the other end having a length exceeding the second pipe, and supported by the second pipe in the middle wherein the respective support leg, said first pipe and means of Ru substantially L-shaped der which horizontally disposed installation legs from the bottom of the vertical strut in one direction toward the longitudinal pipe side for erection of the second pipe Was used.

  In the present invention, similarly to the above-described conventional shelf, two pipes (horizontal frames) are installed between the support legs facing left and right across the drain trap, and the shelf plate is held horizontally by the two pipes. Then, the storage space of the cabinet is divided up and down to increase the storage efficiency.

  Further, in the present invention, both the first and second pipes are located either on the front side or the rear side of the drain trap in a state where the shelf is installed in the cabinet. In other words, the opposite side of the second pipe from the first pipe is an open space. Therefore, even when the first and second pipes are installed on the support legs outside the cabinet and the shelf plate is attached, the first and second pipes can be inserted and installed in the cabinet so that the open space is on the back side. . Moreover, since these pipes and shelves are positioned in front of the cabinet, these members can be assembled in the cabinet relatively easily.

  On the other hand, if it is assembled so that the open space is in front of the cabinet, the article can be stored in front of the drain trap. Also in this case, the pipe can be installed on the support leg outside the cabinet, and the shelf can be installed in the cabinet by rotating the posture so as to wrap around from the lateral side of the vertical pipe. . of course,

  In the above configuration, in the present invention, the shelf board is detachably attached to the first pipe and the second pipe. This is for arbitrarily changing the number and position of the shelf boards. In addition, detachable is defined as including both a configuration in which the shelf can be attached and detached with the pipe attached to the support leg, and a configuration in which the shelf can be attached and removed with the support leg and the pipe disassembled. To do. That is, the former attaching / detaching configuration is typically a fitting or engaging structure such as a hook that is hooked on a pipe, and the latter attaching / detaching configuration is typically a hole through which the pipe is inserted.

  Particularly in the present invention, with respect to the former attachment / detachment configuration, the shelf has a first attachment / detachment portion of a horizontal opening that is pivotably attached to the first pipe at one end, and is downwardly fitted to the second pipe in the middle. It was set as the structure which has the 2nd attachment / detachment part of opening. In this configuration, after the first attaching / detaching portion is fitted or engaged with the first pipe obliquely from above, the shelf can be rotated downward to fit the second attaching / detaching portion to the second pipe.

  In the said structure, the 2nd attachment / detachment part becomes a concave shape of downward opening, and the thickness of the shelf board of the said part is sacrificed by the depth. Moreover, since the shelf of the present invention is supported in a half-cantilever state in which one end side is horizontally supported by two pipes from the center and the other end is completely a free end, the load applied to the other end As a result, a force acts to break the shelf with the second detachable portion as a fulcrum. For this reason, in the present invention, the shelf board is formed in a box shape having a constant thickness in which the side walls are vertically suspended from the left and right sides of the top plate part, and the lower part is opened. The second attachment / detachment portion is formed on the lower edges of the left and right side walls in a manner different from the first attachment / detachment portion. According to this means, since the shelf board has a constant thickness over the entire length, the load resistance of the shelf board is ensured. In this means, the first and second attachment / detachment portions are stepped by the height of the side wall, and accordingly, the first pipe and the second pipe also correspond to the first attachment / detachment portion and the second attachment / detachment portion. It has a step and is installed in a step between the support legs. Therefore, it can support horizontally, ensuring the intensity | strength of a shelf board with such a structure.

  By the way, in order to cope with the horizontal dimension of the cabinet in the cabinet under the sink, the pipe (horizontal frame) that supports the shelf board is made of a telescopic structure with a hollow thick pipe and a thin pipe that can be inserted into the pipe. As is well known, in the present invention, the first pipe and the second pipe are respectively installed between the support legs so that the hollow pipe and the shaft pipe are alternately left and right. According to this means, since the shelf is always supported by both the hollow pipe (thick pipe) and the shaft pipe (thin pipe), the shelf can be supported with a horizontal and uniform load resistance.

On the other hand, the support legs are made up of a plurality of upper and lower detachment holes on both ends of the first and second pipes on the support column, so that the height of the shelf can be adjusted by changing the mounting position of the first and second pipes. It is also possible to provide a plurality of shelves up and down by installing a plurality of first and second pipes on the support legs.

  According to the present invention, since the opposite side of the supporting leg on which the first and second pipes are erected is the open part, it is possible to install the one assembled in advance from the open part in the cabinet. is there. Further, by assembling so that the open portion is positioned in front of the drain trap, the front of the drain trap can be effectively used as a storage space.

The whole perspective view of the storage shelf concerning one embodiment of the present invention. Same as above, top view Side view with one support leg removed Same perspective view of shelf board

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall perspective view of a shelf according to an embodiment of the present invention, and shows a state in which the shelf is installed in a cabinet of a sink. For convenience of explanation, for the cabinet under the sink, only the vertical pipe P with the drain trap T that runs vertically in the storage space under the sink is shown. This will be described as the front door side).

  In FIG. 1, reference numerals 1 and 1 denote a pair of support legs that face each other on the left and right with the vertical pipe P interposed therebetween. The support leg 1 has a substantially L shape in which a first support column 1b is provided vertically at the front end of a horizontal installation leg 1a, and a second support column 1c is provided adjacent to the first support column 1b. In this embodiment, the upper portions of the first and second struts 1b and 1c are integrally connected with a horizontal member for structural strengthening. The first and second struts 1b and 1c are each formed with a plurality of detachable holes 1d and 1e for fixing the pipe with screws 1f.

  The pipe includes a first pipe 2 constructed between the first columns 1b and a second pipe 3 constructed between the second columns 1c. In this embodiment, two sets of the first and second pipes 2 and 3 are installed to exemplify a two-stage configuration. However, the first and second pipes 2 and 3 may be one stage or three or more stages.

  As is apparent from FIG. 2, the first and second pipes 2 and 3 have a stretchable structure in which the shaft pipe 5 is inserted into the hollow pipe 4. Thereby, the space | interval of the support legs 1 and 1 can be adjusted according to the dimension of a cabinet, or the position of the vertical piping P. FIG. As described above, the first and second pipes 2 and 3 have the same structure, but in this embodiment, the hollow pipe 4 and the axial pipe 5 are staggered on the left and right in view of the hollow pipe 4 and the axial pipe 5 having different diameters. Thus, the first and second pipes 2 and 3 are installed between the support legs 1 and 1. That is, the hollow pipe 4 and the shaft pipe 5 are combined in the front and rear. As a result, the load resistance of the entire first and second pipes 2 and 3 can be made uniform. Moreover, the level of the shelf board mentioned later can also be ensured.

  A feature of the present invention is that the second pipe 3 is installed between the first pipe 2 and the vertical pipe P when the support legs 1 and 1 are placed on the left and right sides of the vertical pipe P. In other words, the first and second pipes 2 and 3 are always located at the same time either before or after the vertical pipe P, and the opposite side of the second pipe 3 from the first pipe 2 is open.

  The shelf 6 is held horizontally by the first and second pipes 2 and 3, and, as shown in detail in FIG. 4, the first attaching / detaching portion 6a for the first pipe 2 at one end and the second in the middle. A second attachment / detachment portion 6b for the pipe 3 is formed. Although both the first and second attachment / detachment portions 6a and 6b have a concave shape, in this embodiment, the first attachment / detachment portion 6a is opened in the horizontal direction, and the second attachment / detachment portion 6b is opened downward. ing. Therefore, in order to attach the shelf plate 6 to the pipe, as shown in FIG. 3, first, the first attachment / detachment portion 6a is first engaged with the first pipe 2 obliquely from above, and the entire shelf plate 6 is used with the engagement portion as a fulcrum. Is rotated downward to fit the second detachable portion 6b to the second pipe 3.

  The shelf 6 attached in this way has a length in which the end opposite to the first attachment / detachment portion 6a extends in the horizontal direction beyond the second pipe 3, and the first It will be attached to the second pipe 2.

  Therefore, in this embodiment, the shelf board 6 has a box shape with a constant thickness in which the side walls 6d are vertically suspended from the left and right sides of the top plate portion 6c and opened downward, as is apparent from FIG. The first attachment / detachment portion 6a is formed on the first side, and the second attachment / detachment portion 6b is formed protruding from the lower edge of the side wall 6d. For this reason, the shelf board 6 has a bending strength secured over the entire length by the side wall 6d, and even if it is cantilevered, the second attaching / detaching part is not broken as a weak part.

  On the other hand, since the second attaching / detaching portion 6b is formed so as to protrude from the lower edge of the side wall 6d as described above, the center of the second attaching / detaching portion 6b is shifted downward from the first attaching / detaching portion 6a as shown in FIG. It will be different. In order to cope with such a level difference D, in this embodiment, as shown in FIG. 3, with respect to the support leg 1, the first column 1b and the second column 1c are formed with the level difference between the formation positions of the pipe attachment holes 1d and 1e. The first pipe 2 and the second pipe 3 are erected up and down by the above-mentioned step D by shifting up and down by D. Therefore, the shelf board 6 can be supported horizontally.

  In addition, the through-hole 6e can be suitably formed in the top-plate part 6c of the shelf board 6. FIG. Further, a horizontal rib 6f can be formed inside to reinforce the disconnection by the through hole 6e.

  According to the shelf having the above-described configuration, the first pipe 2 and the second pipe 3 are always positioned either before or after the vertical pipe P, and the opposite side is an open space. When the pipes 2 and 3 are located in front of the cabinet, an assembly assembled outside the cabinet can be installed in the cabinet using the open space. Therefore, there is no trouble of assembling the shelf in the cabinet.

  On the other hand, it is also possible to install the open space so as to be positioned in front of the cabinet. In this case, the front of the vertical pipe P is opened, so that articles can be stored in this portion.

  In short, since the shelf of the present invention is in a state of being disassembled at the manufacturer shipping stage and assembled by the user (end consumer), the user can arbitrarily select which installation mode to use. Even if any mode is selected, it is advantageous to the conventional shelf.

  In the above embodiment, the support leg 1 is L-shaped, but the installation leg may be an inverted T-type extending to the opposite side of the first support column 1b. However, since the shelf board 6 does not exist on the opposite side of the first support column 1b, no load is applied to this side, so the support leg 1 is preferably L-shaped.

  Further, in the above configuration, the shelf plate 6 has the first and second pipes 2 and 3 on the first and second pipes 2 and 3 because the first and second detachable parts 6a and 6b are detachable from the first and second pipes 2 and 3. Can be slid horizontally and can be changed to a proper position. Of course, the number of the shelves 6 and the number of the shelves 6 are not limited to the above embodiment.

  Furthermore, the attaching / detaching portion of the shelf plate 6 with respect to the pipe is not limited to a structure in which a part is opened, and at least one of the attaching and detaching portions may be configured by a through-hole through which the pipe is inserted. In this case, it is necessary to insert the shelf board through the pipe before assembling the pipe to the support leg, but it is possible to eliminate the inconvenience that the shelf board 6 is inadvertently detached from the pipe.
