Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a flip-up folding shelf that can be freely rotated and folded from a horizontal position to a vertical position.

``Prior Art'' An example of a well-known flip-up type folding shelf is the folding shelf introduced in Publication of Utility Model Publication No. 46-6625. Flexible supporting pieces extend rearward from the front ends of both side bodies of the shelf, and protrusions projecting from the rear ends of the support pieces and the rear ends of both side bodies of the shelf are inserted into the upper and lower hook-shaped holes of the upper and lower pillars. By hanging on the
It is constructed so that it can be folded and pulled out in the front and rear directions.

``Problem to be solved by the invention'' By the way, in the folding shelf described above, when folding the shelf backward, it is necessary to press the intermediate bent portions of the support pieces on both sides, and then bend the support pieces and push the shelf upward. The drawback was that it was cumbersome and required time to operate the folding shelves.

Therefore, the present invention aims to provide a folding shelf of the raised type that can efficiently raise and lower the shelf without the above-mentioned operational complexity.

"Means for Solving the Problem" In order to solve the problem mentioned above, a pair of left and right columns are provided, each of which has a clamping device on the upper end for attaching to the side beam of the wall and a spacing device from the wall on the lower end. The upper part of the board of the shelf support arm is rotatably supported on the opposing inner surfaces of both pillars, and the upper part of the board of the shelf support arm is rotatably supported on the opposite inner surfaces of the two pillars. By spanning the shelf board between the above-mentioned shelf support arms, each of which has a locking piece that abuts and engages with the front surface of the support column, and fixing both ends of the shelf board to the shelf support arms, both support posts can be fixed. This constitutes a folding shelf that can be folded up by flipping it up.

``Function'' The shelf that is pivotally supported between the left and right columns via the shelf bracket arms can be easily folded into an upright position between the two columns by pushing up the front end of the shelf, causing both shelf bracket arms to rotate upward. The outer surfaces of both shelf receiving arms elastically contact the elastic protrusions on the inner surfaces of both pillars, thereby fixing them.
In addition, by pulling down the front end of the shelf, it can easily rotate downward and protrude forward from between both supports, and when the shelf is laid down in a horizontal position, the locking piece at the bottom of the board of the shelf support arm abuts and engages with the front face of the support. As a result, the shelf support arm is prevented from rotating excessively further, maintaining a horizontal posture and being able to withstand loads.

"Example" Embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows the entire structure of the folding shelf of the present invention. In the figure, 1 is a column, which is erected facing the wall with the opening surface of the lip groove member as the back, and a lintel at the upper end. A clamping device 2 designed to clamp a horizontal beam such as the above is installed and fixed between the lips on both sides of the opening surface, and a spacing holder 3 in the shape of a chess piece is provided rearwardly protruding from the back of the lower end. The pair of left and right columns are suspended by being clamped to the horizontal beams using the clamping tools, and the vertical posture of both columns is maintained by maintaining a constant distance from the wall surface using the spacing holder at the lower end.

The upper part of the base plate 4a of the shelf support arm 4 is rotatably supported on the opposing inner surfaces of both the support columns 1, 1, respectively, and the pipe shelf board 5 is mounted between the both shelf support arms 4, 4. By doing so, the same type of pipe shelf boards 5 are constructed in two stages, upper and lower, between both supports.

FIG. 2 shows a state in which the shelf support arm 4 is erected along the inner surface of the support column 1, and FIG. 3 shows a state in which the shelf support arm 4 is horizontally projected forward from the support support. As shown in the figure, the shelf support arm 4 has an elongated triangular side surface, a rectangular base plate 4a that is vertically elongated, and an arm portion with a thin front portion protruding from the front end of the base plate 4a. , the arm portion has a horizontal piece 4c from the upper end edge of the elongated hanging piece 4b extending forward from the board 4a, and a rising piece 4d from the inner end edge of the horizontal piece 4c. A locking piece 4e facing outward that abuts and engages with the front surface of the support at the lower end of the edge, and a base plate 4.
A rib 4f is curved inward from the rear end edge, and the upper part of the board is rotatably supported on the inner surface of the column by a shaft 6, and in the horizontal position, the locking piece 4e is attached to the column. By abutting and engaging with the front surface, downward rotation is prevented and a horizontal posture is maintained, and when the hanging piece 4b is in an upright posture along the inner surface of the column, the front end of the hanging piece 4b comes into elastic contact with the elastic protrusion 7 and is fixed. and maintain a vertical position. In addition, 8 in FIG. 3 indicates a set screw for tightening and fixing the shelf board, which will be described later, on the shelf support arm 4,
An insertion hole A for this set screw is provided in the center of the horizontal piece 4c.

FIG. 4 is a partially cross-sectional side view of the folding shelf in the horizontal position, in which the clamping tool 2 provided at the upper end of the column 1 is used to change the side shape in order to fit into the lintel 9. Upper horizontal piece 2a of the opening formed in the shape of a letter
A prick 2b was provided at the rear end, and this was inserted into the upper surface of the lintel, and the lower end of the hanging piece 2c was bent into a U-shape to form a recess 2d in the opposite direction to the upper opening, and it was loosely fitted into the recess. A sliding tightening plate 12 is orthogonally fixed to the upper end of a screw rod 11 which is screwed into the center of the rotating nut 10 and passes through the recess, and by twisting the rotating nut 10 in forward and reverse directions, The sliding tightening plate 12 is moved forward and backward in the vertical direction to tighten or loosen the lintel 9.

In addition, the spacing holder 3 provided at the lower end of the column is constructed by screwing a spacing adjustment screw 3b into the center of a Chiss piece-shaped base 3a that is in contact with the wall surface W, and then screwing the spacing adjustment screw 3b into the center of the
c is fixed to the lower end of the column by welding it to the inner surface of the front wall of the column 1, and the table 3a is twisted along the screw 3b to move forward and backward to adjust the distance from the wall surface.

In addition, the pipe shelf board 5 is constructed by inserting the ends of seven pipes 5a arranged at equal intervals into the grooved side frame 5b, and covering the upper side of the pipe ends with corrugated reinforcements 5c. Tighten and secure from the recess with screws 5d... to form a one-sided shelf board, which is then placed between the left and right shelf support arms, and tighten it to the lower wall of the side frame 5b with setscrews 8 from the underside of the shelf support arms. It is fixed on the shelf support arm.

FIG. 5 shows a left part of the front view of the state shown in FIG. 4 when viewed from the front. 13 in the figure indicates a cap fitted to the lower end of the column.

``Effect of the invention'' Both ends of the shelf are fixed to both shelf support arms that are rotatably supported on the opposing surfaces of the left and right columns, making it easy to operate by simply pushing and pulling the front end of the shelf. The shelves can be raised and rotated, and the operation is light, so the operation of folding and folding drawers is simple, quick, efficient, and hassle-free. Then, when the shelf is pulled forward and assumes a horizontal position, the locking piece connected to the elongated triangular-shaped vertical piece of the shelf support arm engages with the front surface of the column, preventing further rotation. The hanging piece and the locking piece have a triangular structure and have a supporting force against the load of the articles placed on the shelf. When the shelf is rotated upward and stands up along the inside of the column, the outer surface of the tip of the shelf support arm comes into elastic contact with the elastic protrusion protruding from the inner surface of the column. By increasing the length between the pivot shaft, which is the fulcrum, and the elastic protrusion, which acts as the fulcrum, the arm is firmly fixed in that position, maintaining an upright posture, and preventing the shelf from falling forward. prevent.

Because of this, when the shelf is not needed, it can be immediately flipped up and folded up along the wall surface, and when needed, it can be easily pulled out and used.

Furthermore, the upper ends of both the left and right columns are attached to the lintel using clamping tools, and the lower ends are in contact with the wall using spacing tools, so loosen the clamping tools on the upper ends to remove them from the lintel. As a result, the entire hanging shelf can be easily moved to another position, and it is easy to move the hanging shelf to any desired location.
