Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a device for attaching a removable drawer auxiliary shelf to the main shelf, which is attached in a pull-out manner to the underside of the main shelf.

"Prior Art" The drawer auxiliary shelf of the invention related to the utility model registration application dated October 25, 1985, which is the applicant's earlier application, is
An intermediate support that slidably supports the auxiliary shelf side frame is slidably and pivotably supported on the horizontal sliding rod of the hanging frame, and the upper ends of both the front and rear vertical frame rods of the hanging frame are The horizontal mounting plate is fixed to both the front and rear ends of the horizontal mounting plate, and the horizontal mounting plate is fixed to the main shelf using a clamp plate and a suspension screw, and the auxiliary shelf can be slid freely through the intermediate support. The support height of the auxiliary shelf can be changed to two different heights by supporting it on the hanging frame and installing it in a pull-out manner on the underside of the main shelf, and by moving the intermediate support up and down using the horizontal sliding rod of the hanging frame as the rotation axis. It is configured so that it can be done.

``Problems to be solved by the invention'' By the way, in the drawer auxiliary shelf mentioned above, when rotating the intermediate support in order to change the support height of the auxiliary shelf, the suspension frame mounting plate on one side must be rotated. Unless the clamping fixation is loosened and the hanging frame is slid outward to widen the gap between the left and right hanging frames, the intermediate support cannot turn inward and rotate upward or downward;
After the rotation is completed, the hanging frame must be repositioned and tightened, which is a complicated operation and makes it impossible to adjust the height of the auxiliary shelf.

Therefore, in the present invention, we have developed an auxiliary shelf mounting system that allows the intermediate support to be rotated quickly by easily adjusting the interval between both hanging frames without requiring the above-mentioned complicated operations, and that allows for efficient height adjustment of the auxiliary shelf. This is an improvement to the mounting part of the earlier application in order to make it into a device.

"Means for Solving the Problem" As a means for solving the above problem, in the drawer auxiliary shelf of the earlier application, the upper ends of both the front and rear vertical frame rods of the hanging frame on either the left or right side were horizontally adjusted. The suspension frame is pivotally attached to the front and rear of the mounting plate so that it can rotate in the left and right directions, allowing the hanging frame to rotate outward to open the bottom wide or close inward, and also to pivot the front vertical frame rod. A rotation control piece is installed inside the rotation part so as to be slidable back and forth along the inner edge of the horizontal mounting plate, and the hanging frame is always pressed inward at the pivoting part of the rear vertical frame rod. The central part of such a pressing body is wound around the rotating shaft, and the bullet pieces on both sides are engaged with the mounting plate and the steadying rod at the lower part thereof, and the horizontal mounting plate of the hanging frame constructed in this way is clamped. It is fixed to the underside of the main shelf using a board and hanging screws.

"Function" Since the structure of the one-side hanging frame is configured as described above and the hanging frame is attached to the main shelf so that it can be rotated in the left and right directions, it can be rotated outward and the lower part thereof can be removed. By opening it in the opposite direction, it becomes possible to increase the distance between the suspension frame on the other side and rotate the intermediate support by half a turn up and down on the inside of the suspension frame around the horizontal sliding rod. It has become easy to change the support height of the auxiliary shelf to two different heights while keeping the mounting plate fixed without loosening the clamping part of the side hanging frame.

Furthermore, since the hanging frame body is always pressed inward by the pressing body provided at the rear end of the mounting plate, after opening the one side hanging frame body outward and rotating the intermediate support half a rotation, the hanging frame body The body quickly returns to its original position due to the pressing force of the pressing body and maintains its vertical position together with the hanging frame on the other side, so the auxiliary shelf is stable without swinging from side to side, and its back and forth sliding progresses. is smooth.

"Example" An example of the present invention will be explained with reference to the attached drawings.
As shown in Figures 1 and 2, the drawer auxiliary shelf is installed by installing an auxiliary shelf B on the lower side of a pipe hanging shelf (referred to as the main shelf) A via a hanging frame C and an intermediate support D. The auxiliary shelf B can be pulled out from the bottom of the main shelf to the front by suspending the support from the main shelf. This is an installation state in which the support position of B is raised and it slides back and forth, and the one shown in Fig. 2 is a state in which the support position of the auxiliary shelf B is lowered by positioning the intermediate support body D at the lower part of the hanging frame C. The mounting state is such that it slides back and forth, and the operation of adjusting the support height of such an auxiliary shelf can be performed by rotating the intermediate support D by half a turn up and down. This will be described later based on detailed drawings from FIG. 3 onwards.

The main shelf A is a pipe shelf in which both ends of several parallel pipes 1 are integrally connected with clamping connectors 2, and is suspended from a shelf hanging frame 3 at a desired location.

The auxiliary shelf B is made by bending a certain width of both the front and rear edges of the net plate 4 upward, and attaching the upper edge of both the front and back folds to the rectangular frame 5.
The front frame rod 5a and the rear frame rod 5b are welded to each other, and a U-shaped flat band-shaped edging material 6 is attached along both left and right edges of the rim frame 5. The rods 5c and 5d are provided so as to project slightly outward from the side ends of the husbandry edge material 6.

The hanging frame C is a horizontal mounting plate having a length equal to the width of the front and back of the main shelf to be attached to the lower side of the main shelf A, as shown in enlarged views of the main part in Figs. 3 and 4. 7
A downward bent edge 7a is formed along the inner edge of the lower bent edge 7a, and an elongated hole 7b is formed in the front end of the downward bent edge 7a. The screw holes 7e, 7e are carved in the center front and rear parts of the upper plane 7d, and the screw holes 7e
Attach the clamp plate 9 to the suspension screw rod 8, 8 which is screwed into both the front and rear through-holes 9.
a, 9a, and as shown in FIGS. 1 and 2, the central pipe 1 of the main shelf A is clamped and fixed by the clamp plate 9 and the suspension screws 8, 8. It's like this.

In addition, in the circular pipe portions 7c, 7c at both the front and rear ends of the mounting plate,
Both the front and rear vertical frame rods 10 of the frame rod 10 whose side shape is a horizontally elongated U shape
Bent horizontal shafts 10a' and 10b' at the upper ends of a and 10b are rotatably mounted, and the lower side of the horizontal mounting plate 7 is located between the front and rear vertical frame rods 10a and 10b of the frame rod 10. A steady rod 10c and a horizontal rod 10 at the bottom end
Horizontal sliding rods 10e are mounted parallel to each other on the upper side of d, and both the front and rear vertical frame rods are mounted between the vibration damping rod 10c and the horizontal sliding rod 10e. Since the lower parts of both vertical frame rods are deflected inward by consecutively bending them twice in a dogleg shape, the lower end horizontal rod 10d is located directly below the steadying rod 10c, and the horizontal sliding rod 10e is located directly below the steady rod 10c. It is deviated inward by the rod.

Furthermore, at the front end of the horizontal mounting plate 7, the upper horizontal shaft 1 of the vertical frame rod 10a is pivoted to the circular pipe portion 7c.
A rotation control piece 1 whose extension end of 0a' is bent further inward so that it can be engaged with and disengaged from the inner end of the inwardly directed piece 10a''.
1 is installed inside the mounting plate so as to be slidable back and forth along the inner bent edge 7a, and the inner end protrusion 11a of the rotation control piece 11 is made to protrude inwardly from the elongated hole 7b. The rotation of the frame rod 10 can be controlled or released by engaging and disengaging the rotation control piece 11 and the inwardly directed piece 10a'' by sliding it back and forth within the frame.

Furthermore, at the rear end of the horizontal mounting plate 7, the center part of the pressing body 12 is wrapped around the horizontal shaft 10b' at the upper end of the rear vertical frame rod 10b, and the inward elastic piece 12a of the pressing body is attached to the horizontal mounting plate with the inner end. 7, and the lower end of the downward elastic piece 12b is engaged on the steadying rod 10c.
The lower part of the hanging frame is always pressed inward to prevent the hanging frame from swinging laterally and to stabilize it.

The intermediate support D, together with the suspension frame C, is formed to have the same length as the horizontal sliding rod 10e, as shown in partially enlarged views in FIGS. 3 and 4, and its rear half 1
4 is inserted into a horizontal sliding rod 10e and is supported as a shaft, and the front half 13 and the rear half 14 are formed into a step-like shape with two steps in height,
Its structure consists of an outer shell 15 in which the intermediate portions of both the front and rear steps are continuous in a crank shape, and the inner surface is opened to form a variable groove shape.
Both the front and rear filling bodies 16, 17 are fitted into the inside of the front filling body 16 so as to be integrated, and the insertion hole 1 of the side frame rod 5d of the auxiliary shelf B is inserted in the longitudinal direction of the central part of the front filling body 16.
6a, and an insertion hole 17a for the horizontal sliding rod 10e of the hanging frame C in the longitudinal direction of the center length of the rear filling body 17, so that the horizontal sliding rod 10e and the husband auxiliary shelf side frame rod can be horizontally slid into both the insertion holes 16a, 17a. By inserting the rod into the horizontal sliding rod and bearing the intermediate support on the horizontal sliding rod, and bearing the auxiliary shelf side frame on the intermediate support, the auxiliary shelf is movably connected to the hanging frame through the intermediate support, and Both shaft bearings are slidable forward and backward relative to each other, and the auxiliary shelf is suspended from the main shelf in a pull-out manner.

In addition, what is shown in FIG. 3 shows a state where the front half 13 of the intermediate support is placed higher than the rear half 14, and what is shown in FIG. The figure shows a state in which the front half 13 is placed lower than the rear half 14 by rotating the front half 13 to a lower position than the second half 14, and the upper-lower conversion operation of the first half is performed by moving the intermediate support D around the horizontal sliding rod 10e as the rotation axis inside the hanging frame. The second half moves up and down around the horizontal sliding rod, and as the first half rotates along its outer periphery in a semicircular arc, the second half rotates in the first half insertion hole. The auxiliary shelf side frame rod slides against the hole wall and rotates from above to below.

The procedure for this upward/downward conversion operation will be explained with reference to FIGS. 5 to 7.

First, when the auxiliary shelf B is supported above as shown in FIG. 5, the front half 13 of the intermediate support is above the horizontal sliding rod 10e. The rear end of the rotation control piece 11 of the right side suspension frame engages with the inwardly directed piece 10a'' to control its rotation (see FIG. 3).

Next time you try to move the auxiliary shelf lower,
After pulling the protrusion 11a of the rotation control piece to the front end of the elongated hole 7b on the right hanging frame body and retracting the control piece 11 to release the rotation control of the frame rod 10, move the lower part of the frame rod outward. When pulled, the horizontal shafts of the upper ends of both the front and rear vertical frame rods rotate within the circular tube part 7c, and as shown in Fig. 6, the lower part of the right side suspension frame opens, widening the distance from the left side suspension frame while moving the right side support. At the same time, it also pulls the front half of the left support body inward via the auxiliary shelf and rotates it.

If you proceed further, the left side support and the right side support will be oriented vertically in the opposite direction, and as shown in Figure 7, both sides of the support will hang downward, and both supports will hang in parallel, creating an auxiliary shelf. moves to a lower position, moves away from the main shelf, and is supported low. At that time, the rotation control piece 11
Push the protrusion 11a into the front end of the elongated hole 7b to fix the rotating part.

In the state shown in Fig. 5, the anti-sway rods 10c on the tops of both the left and right suspension frames slide against the upper outer surfaces of the intermediate supports and support both outer sides, so that the intermediate supports on both sides do not sway laterally. The auxiliary shelf is also stably stabilized without causing damage, and since the intermediate support slides along the anti-vibration rod, the auxiliary shelf can smoothly slide back and forth without any hindrance to its operation.

In addition, in the state shown in Fig. 7, the lower end horizontal rods 10d of both the left and right suspension frames enter the central outer recesses of both intermediate supports and slide into contact with the outer surfaces to support both outer sides and serve as a vibration prevention rod. Therefore, both intermediate support bodies are stable without sideways vibration, and the auxiliary shelf is also stabilized.Since the intermediate support body slides along the horizontal rod, the auxiliary shelf can slide back and forth smoothly, and its operation is not hindered. do not have.

``Effect of the invention'' At the lower side of the mounting plate of the hanging frame of the auxiliary shelf, a horizontal axis (rotation axis) is provided at the upper end of both the front and rear vertical frame rods of the hanging frame, and this can be rotated to the front and rear outer edges of the mounting plate. Now that it is freely pivoted, with the mounting plate fixed to the bottom of the main shelf, rotate the hanging frame outward to open it, widen the gap with the hanging frame on the opposite side, and move both intermediate supports to the inside. Therefore, it is not necessary to convert the support height of the auxiliary shelf to two different heights, and the conversion operation can be performed easily and quickly.

In addition, by providing a rotation control piece that can be slid back and forth at the shaft attachment part of the upper end of the front vertical frame rod, the rotation of the hanging frame is restricted and immobile when it is not necessary. is stable and does not sway horizontally, thus also stabilizing the auxiliary shelf.

In addition, the outer part of the intermediate support is supported by the parallel steady rods and lower end horizontal rods provided on the suspension frame, and the suspension frame is pressed inward by a pressing body provided on the rear side. The auxiliary shelf is stabilized by providing a steady rest to the outside, and therefore the back and forth sliding operation of the auxiliary shelf is made smooth.
