Description

  The present invention relates to a shelf for placing a box that stores articles, and more particularly to a shelf for placing an article storage box that can be easily assembled and folded in a short time without requiring a special tool.

  The main type of shelf is a fixed type that has a fixed number of steps and width and cannot be disassembled. However, since the fixed type cannot be disassembled, there is a problem that it is difficult to store when not in use. In order to solve this problem, various article placement shelves that can be assembled and folded have been proposed.

  For example, in Patent Document 1, a central shelf support is erected on a base frame provided with moving wheels, and one end of a plurality of shelf members is provided at predetermined intervals on both the left and right sides of the central shelf support. The central shelf support and the pair of left and right side shelf supports are pivotally attached and pivotally attached to the side shelf supports in which the other ends of the shelf members are made to stand upright on the left and right sides of the center shelf support, respectively. A support member that supports the shelf member group arranged in a substantially horizontal state at a predetermined interval in the vertical direction and holds the folded state when the shelf member group is folded to the central shelf support side. A foldable storage shelf has been proposed. However, in the case of this storage shelf, since the vertical height in the folded state becomes very high, there is a problem in use and movement in a room with a low ceiling.

  In Patent Document 2, the main body rack is composed of a rear frame and left and right frames, the left and right frames are hinged to the rear frame, the top of the main body rack is a plate-shaped metal piece, and the bottom is four support legs. The rear surface of the top plate is provided with at least one rear fitting part, at least one left fitting part, and at least one right fitting part, and the rear fitting part and the left and right fitting parts. The position of the joint part corresponds to the position of the plate metal piece at the top of the rear frame and left and right frames respectively, the horizontal wire consists of the left horizontal wire and the right horizontal wire, and one of the left horizontal wire can be attached to and detached from the left frame Fixed, the other side is detachably fixed to the rear frame, one side of the right side wire is detachably fixed to the right frame, and the other side is detachably fixed to the rear frame. Horizontal wire forms a bearing surface of a triangle on the same plane, and wherein the placing the drawer on the bearing surface of the triangle, storage cabinets that can be assembled without tools fast is disclosed.

  However, in the case of this storage cabinet, the left and right frames are hinged to the rear frame, and the side that is not hinged is simply connected by a detachable left lateral wire and right lateral wire. Further, the left lateral wire and the right lateral wire only form a triangular support surface on the same plane and form a support surface on which the drawer is placed. Since the wire is weak in compressive force, the horizontal shape of the cabinet is easily deformed when force is applied to the front column of the left and right frames from the diagonally front side of the cabinet. Further, since the support surface is also formed of a wire, it is easy to loosen due to the weight of the placement drawer. Furthermore, since there is no support at the front part of the cabinet, there is a problem that when the drawer with a small width is placed, the drawer easily falls.

  Hereinafter, an embodiment of a mounting shelf for mounting an article storage box according to the present invention will be described with reference to the drawings. There are two types of article storage shelves of the present invention: a mounting shelf provided with a top plate 10 to be described later, and a mounting shelf without a top plate 10. Will be described. FIG. 1 is an external perspective view of a mounting shelf 1 having three shelves with a top plate 10, and FIG. 2 is an external perspective view of a state in which an article storage box 2 is mounted on each shelf of the mounting shelf 1. FIGS. 3 and 3 are exploded perspective views of the mounting shelf 1. As shown in FIG. 3, the mounting shelf 1 includes a back frame body 3, a left frame body 4, a right frame body 5, a top plate 6 and a shelf surface component 6. The shelf surface components 6 are three front horizontal pipes 6a and six front / rear horizontal bars 6b.

  FIG. 4 is a perspective view showing each configuration of the back frame body 3, the left frame body 4, and the right frame body 5, and their combined configuration. The back frame 3 is a frame that constitutes the back wall of the mounting shelf 1, and is a portal-shaped frame comprising a top frame 3 a, a left frame 3 b, and a right frame 3 c having the same length by bending a square pipe or a round pipe into a reverse concave shape. An outer peripheral skeleton is formed, and pipes are stretched horizontally and vertically inside the portal skeleton.

  A plurality of horizontal pipes 3d are stretched between the left frame 3b and the right frame 3c of the back frame 3. The horizontal pipe 3d is a pipe that reinforces the portal skeleton and supports the shelf surface component 6 constituting the shelf surface and receives the load of the article storage box 2 placed thereon. The horizontal pipe 3d may be a square pipe or a round pipe. The number of horizontal pipes 3d is equal to the number of shelf surfaces, which is three in the case of this embodiment. The horizontal pipes 3d are attached at equal intervals from the upper frame 3a to the lower side. The interval is slightly larger than the height of the article storage box 2 to be placed. Furthermore, a plurality of vertical pipes (or bars) 3e are stretched across the back frame 3 in the vertical direction. The vertical pipe 3e is attached between the upper frame 3a and the lowermost horizontal pipe 3d so as to pass through each horizontal pipe 3d. The vertical pipe 3e reinforces the portal skeleton and, at the same time, prevents the placed article storage box 2 from dropping backward.

  The left side frame 4 and the right side frame 5 are frames constituting the left and right walls of the mounting shelf 1, and use pipes having the same cross section as that used for the gate-type outer peripheral skeleton of the back frame 3 as shown in FIG. And formed into a rectangular frame. A plurality of horizontal pipes 4c and 5c are horizontally stretched between the left frames 4a and 5a and the right frames 4b and 5b. The right frames 4b and 5b have the same length as the left and right frames 3b and 3c of the back frame 3. The left frames 4a and 5b are shorter than the left frames 4a and 5b, and are slightly shorter than a value obtained by multiplying the shelf interval by the number of shelves (3 in this embodiment). For this reason, the lower ends of the right frames 4b and 5b are in a state of projecting downward from the lower frames 4e and 5e of the rectangular frame.

  The left frame 4a of the left frame 4 and the left frame 5a of the right frame 5 are connected to the left frame 3b and the right frame 3c of the back frame 3 so as to be able to turn horizontally by using hinges 7, respectively. The left frame 4, the upper frame 4 d and the upper frame 5 d of the right frame 5 have the same height as the upper frame 3 a of the back frame 3. FIG. 5 is an enlarged view of a portion of the hinge 7 that connects the left frame 4 a of the left frame 4 to the left frame 3 b of the back frame 3. One hinge part having an L shape is formed on the front side of the left frame 3b of the back frame 3, that is, the side facing the left frame 4, and the other L is provided on the side of the left frame 4a of the left frame 4 on the back frame 3 side. The hinge parts are attached by welding, and the two hinge parts are connected by bolts so that they can be turned horizontally.

  FIG. 6 is a plan view of a state in which the left frame 4 and the right frame 5 are connected to the back frame 3. The left side frame body 4 and the right side frame body 5 can be horizontally swiveled by a hinge 7 connection around the left frame 3b and the right frame 3c of the back frame 3, respectively. When used as the mounting shelf 1, the frame surfaces of the left frame body 4 and the right frame body 5 are perpendicular to the frame surface of the back frame body 3, and the back frame body 3, the left frame body 4, and the right frame body 5 are The arrangement is reverse concave in plan view. When storing when not in use, the left side frame 4 and the right side frame 5 are rotated as shown in FIG. Since the width of the left frame 4 and the right frame 5 is slightly narrower than ½ of the width of the back frame 3, the left frame 4 and the right frame 5 are shown in FIG. As shown in FIG. 16, the rear frame 3 is completely overlapped. In this way, the angle between the frame surfaces of the left frame body 4 and the right frame body 5 and the frame surface of the back frame body 3 can be turned within a range including 0 to 90 degrees.

  A plurality of horizontal pipes 4 c and 5 c are stretched horizontally between the left and right frames of the left frame 4 and the right frame 5. The horizontal pipes 4 c and 5 c reinforce the left frame 4 and the right frame 5, and at the same time prevent the article storage box 2 placed on the mounting shelf 1 from protruding from the left frame 4 and the right frame 5 to the left and right outer sides. . The horizontal pipes 4c and 5c are attached to a height position slightly above the height position of each horizontal pipe 3d attached to the back frame 3. The number is one less than the number of horizontal pipes 3 d of the back frame 3. This is because the protrusion of the article storage box 2 placed on the lowermost shelf to the left and right outside is not necessary because it is prevented by the lower frame 4e of the left frame 4 and the lower frame 5e of the right frame 5. .

  3 between the right frame 4b of the left frame 4 and the right frame 5b of the right frame 5 arranged in a reverse concave shape in plan view, that is, on the front side of the mounting shelf 1, is the shelf surface component 6 shown in FIG. The front horizontal pipe 6a of the book is detachably stretched horizontally. The height of each of the three front horizontal pipes 6a is the same as the height of the three horizontal pipes 3d attached to the back frame 3. FIG. 7 is a perspective view of a state in which three front horizontal pipes 6a are attached to the front side of the left side frame body 4 and the right side frame body 5 forming the reverse concave shape shown in FIG.

  (1) of FIG. 8 is a view of the left frame 4 as viewed obliquely from the rear, and is a view showing a state in which the front horizontal pipe 6a is attached to the right frame 4b of the left frame 4. (2) of FIG. 8 is an enlarged view showing a structure in which the front horizontal pipe 6a is detachably attached. An L-shaped metal fitting 8 provided with a round protrusion directed upward is attached to the inside of the right frame 4b, and the front horizontal pipe 6a provided with a hole for fitting the protrusion on the lower surface is placed with the protrusion fitted in the hole. And attach. The number of front horizontal pipes 6a is equal to the number of shelves, and the height of each front horizontal pipe 6a is made to coincide with the height of the horizontal pipe 3d attached to the back frame 3.

  FIG. 9 is a perspective view in which the front-rear horizontal bar 6b is attached to the frame body to which the front horizontal pipe 6a shown in FIG. 7 is attached. FIG. 9 is a configuration diagram of a mounting shelf in which the top plate 10 is not provided. The horizontal bar 6b in the drawing is a round bar having both ends short and bent at a right angle as shown in FIG. The front-rear horizontal bar 6b is inverted in the shape of a reverse letter C between the horizontal pipe 3d attached to the back frame 3 and the front horizontal pipe 6a attached between the right frames 4b and 5b of the left frame 4 and right frame 5. It is detachably stretched.

  FIG. 10 is a cross-sectional view of the frame body with the front-rear horizontal bar 6b attached, cut horizontally at a frame height of ½ and viewed from below. The front-rear horizontal bar 6b is stretched between the horizontal pipe 3d of the back frame 3 and the front horizontal pipe 6a in an inverted C shape. Instead of stretching in a reverse C shape, it may be stretched in a C shape as shown in FIG. The front-rear horizontal bar 6b is a bar that constitutes a shelf surface, and contacts the lower surface of the article storage box 2 to support it.

  In addition, an important role of the front-rear horizontal bar 6b is to maintain the horizontal cross-sectional shape of the mounting shelf 1 in a square shape. Even if a horizontal force is applied from the front lateral direction or the front diagonal direction to the mounting shelf 1 having a square horizontal section, the horizontal section is maintained in a square shape and is not deformed. In order to exert such a function, it is a major feature of the mounting shelf 1 that the front and rear horizontal bars 6b constituting the shelf surface are stretched in an inverted C shape or a C shape. If it is stretched parallel to the frame surfaces of the left frame 4 and the right frame 5 without being stretched in an inverted C shape or C shape, the right frame 4b of the left frame 4 or the right frame 5 When force is applied to the right frame 5b from the lateral direction, the quadrilateral shape of the horizontal section is broken and deformed into a parallelogram. This is because the back frame 3, the left frame 4, and the right frame 5 do not have a function of fixing at right angles to the frame surface, and are only connected so as to be pivotable by the hinge 7. On the other hand, in the mounting shelf 1 of this embodiment, since the front-rear horizontal bar 6b is stretched in an inverted C shape or a C shape, the deformation is prevented and the square shape is maintained.

  FIGS. 12, 13, and 14 show the attachment structure of the front / rear horizontal bar 6b to the front horizontal pipe 6a. The front horizontal pipe 6a is detachably attached. In FIG. 12, a hole 9 is provided in the front horizontal pipe 6a as shown in FIG. (1), and the portion bent at a right angle of the front-rear horizontal bar 6b is inserted into the hole 9 as shown in FIG. It is a structure attached with. FIG. 13 shows a structure in which a short round pipe is welded upward on the side surface of the front horizontal pipe 6a as shown in (1), and the tip is inserted into the hole of the pipe. FIG. 14 shows a structure in which, as shown in (1), a rectangular plate having a hole in the side surface of the front horizontal pipe 6a is attached by welding and the tip is inserted into the hole. Any structure may be used. The rear frame 3 is attached to the horizontal pipe 3d side with the same structure.

  FIG. 15 is a perspective view of the top plate 10 used for a mounting shelf of a type to which the top plate is attached as viewed from the upper surface side. The top plate 10 is a quadrangular plate that covers the upper open portion in a state in which the back frame body 3, the left frame body 4, and the right frame body 5 are in a concave shape in plan view. On the lower surface side, a concave component 10a sandwiching the upper frame 3a of the rear frame 3 and the upper frames 4d and 5d of the left and right side frames 4 and 5 from above is provided with at least one location of each upper frame 4d and 5d. It is attached downwards at the pinch position. The concave parts 10a are attached so as to cover the upper open portion with the upper frames 3a, 4d and 5d sandwiched therebetween. Since the concave component 10a sandwiches the upper frames 3a, 4d, and 5d, the top plate 6 is prevented from being displaced. The overall appearance of the mounting shelf 1 on which the top plate 6 is placed is shown in FIG.

  The mounting shelf 1 of this embodiment described above can be assembled without using a special tool. Moreover, when not in use, disassembly is possible without using a special tool. FIG. 16 shows a folded state for storage when not in use. Since the left side frame body 4 and the right side frame body 5 can be folded on the back surface frame body 3, it becomes compact. In addition, it is convenient to move the casters attached to the legs of each frame. In the case of a mounting shelf having a configuration in which the top plate 10 is not provided, there is no height limitation on the article storage box placed on the uppermost shelf, and there is an advantage that a tall article storage box can be placed.
