Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention involves rotating the front door that closes the front of the cabinet horizontally around its top, and then pushing it into the cabinet to open it. This invention relates to an opening/closing device for a retractable front door.

(Prior art) Such a front door opening/closing device was developed in Utility Model Publication No. 42-4030
Publication No. 11861-11861, Publication No. 11861, Publication No. 11861
This is disclosed in Japanese Utility Model Publication No. 33233, Japanese Utility Model Publication No. 60-3251, and the like.

(Problems to be solved by the present invention) The devices disclosed in Publication of Utility Model Publication No. 42-4030 and Publication of Publication of Utility Model Publication No. 60-3251 have a horizontal front door,
Since the front door is inserted and removed along the upper surface of the support rod or support bar that is parallel to the shelf board, the sliding of the front door when taking it in and out produces an unpleasant sound, and the operation is not easy and the sliding movement is difficult. The moving surfaces, especially the tip of the receiving material and the upper part of the back of the front door, are prone to wear and tear.

In the case disclosed in Japanese Utility Model Publication No. 48-11861 and Japanese Utility Model Publication No. 48-33233, a roller pivoted at the front of the side panel of the cabinet serves as a pivot point for rotation when the front door is inserted or removed. The rollers and roller shafts are subject to significant wear and tear, and the work of attaching the rollers to the side plates is troublesome.

In addition, in each of the above-mentioned devices, when the front door is put in and taken out, the front door swings laterally and the side panels of the front door rub against each other, causing significant wear and tear on this part and producing unpleasant noises.

(Means for Solving the Problems) The present invention consists of a side-opening channel-like structure, which is installed in the front-rear direction at key points on the opposite surface of the side plate or the partition plate parallel to the side plate in the front-opening cabinet. A rail of a predetermined length with a closed rear end, and a vertical rear face that is erected at the front end of the rail, closes the front end of the rail, and extends downward from the upper end of the rear face that protrudes upward from the rail. A steady rest made of synthetic resin has a continuous curved surface facing towards it, and a steady rest with the upper end protruding above the curved surface on the outer surface, and rollers pivoted at key points on the side allow it to run freely on the rail. When mated, when the roller is at the front end of the rail, it is approximately vertical and closes the opening surface of the cabinet, and when the roller is at the rear end of the rail, it is approximately horizontal within the cabinet and opens the cabinet. The above-mentioned problems are solved by providing a front door opening/closing device consisting of a front door.

(Function) In the device of the present invention, if the closed front door is horizontal with its roller axis as the rotation axis,
You can easily open the door by pushing it along the rail until it touches the stopper at the rear end of the rail, and if you pull it out forward, the roller will lock into the stopper at the front end of the rail and hold it in place. It stops and the door closes under its own weight.

The front stopper is made of synthetic resin that slides easily, and has a curved surface on the front, so it can be rotated smoothly when the front door is inserted or removed.

Furthermore, since the upper end of the stopper protrudes above the rail, the back surface of the front door does not touch the rail while the front door is being taken in and out, and after the door is opened and closed.

Furthermore, since a steady rest is provided, the side of the front door does not touch the adjacent side panels or other front doors due to swinging when the front door is being inserted or removed. There will be no damage to the sides or generation of unpleasant noises during loading and unloading operations.

As shown in FIGS. 3 and 5, angle-shaped shelf supports 8 facing in the front-rear direction are fixed near the upper end of the inner surface of the shelf support plate 5 and the lower end of the inner surface of the shelf support plate 6. Upward locking pieces 9 are cut and raised near both front and rear ends of the receiving member 8.

By supporting the lower ends of both side pieces 10a of the shelf board 10 on the shelf support material 8 and engaging with the locking pieces 9, the shelf board 10
It is constructed in

As shown in FIG. 4, FIG. 6, and FIG. 8, the lowermost end of each bent piece 10b, which is bent downward at both the front and rear ends of the shelf board 10 and has a U-shaped side surface, has a lowermost end. Except for the shelf board 10, a horizontal piece 11a curved at the upper edge of the hanging support plate 11, which has almost the same shape as the shelf support board 5, has a downward U-shaped side surface.
2, it is fixed so as to be movable laterally with a screw 13 passing through the horizontal piece 11a from below.

As shown in FIGS. 3 to 6 and 8,
At a predetermined location on the inner surface of each shelf support plate 5 and on both sides of each suspension support plate 11 (as shown in the figure, if the vertical width of the shelf support plate 5 and suspension support plate 11 is short, the lower end) A channel-shaped guide rail 14 facing further rearward and opening on the side is fixed.

A rear stopper 15 is provided at the rear end of the rail 14 to close the rear end opening, and a front stopper 16 made of synthetic resin is provided at the front end, the outer surface of which overlaps with the shelf support plate 5 or the hanging support plate 11. has been erected.

As shown in FIG. 4, the vertical rear surface 16a of the front stopper 16 closes the front end opening of the rail 14 and projects slightly upward from the upper surface of the rail 14. An arcuate curved surface 16b extending forward and downward is formed from the upper end of the front stopper 16, and a steady rest 16c whose upper end projects upward from the curved surface 16b is also connected to the outer surface.

Reference numeral 17 denotes a front door, and as shown in Figures 3, 4, 6, and 8, when the front door 17 is set vertically, the lower end and center of the front are for displaying magazines, etc. A receiving groove 18 and a support frame 19 are attached, and rollers 21 facing outward are pivotally mounted near the upper ends of both sides with mounting plates 20 facing rearward.

The rollers 21 of each front door 17 fit into the left and right opposing rails 14, and the front stopper 16 of each front door 17 is normally connected to the front stopper 16 like the upper front door 17 in FIG.
It abuts on the rear surface 16a and is suspended substantially vertically, with its lower end close to the front end of the lower surface of the shelf board 10, thereby closing the opening between the two shelf boards.

If the lower end of the front door 17 in this state is lifted, the front door 17 will be guided by the curved surface 16b of the front stopper 16 with both rollers 21 as axes, rotate upward and become horizontal, as shown in FIG. lower front door 17 in
