Description

[Detailed Description of the Invention] This invention relates to a drawer device used for furniture, etc., and particularly relates to a guide support structure for a drawer.

In a general guide support structure for a drawer, the side plate of the drawer has
A guide groove (or a sliding step) is formed almost entirely in the front-rear direction, and a sliding step (or a guide groove) is formed on the facing surface of the vertical plate of the main body of furniture, etc., which is in contact with the side plate. A structural system is adopted in which the drawer can be freely opened and closed by sliding on the slider (or inside the guide groove) where guide grooves (or slides) play with each other.

By the way, in this type of conventional drawer device, there is a drawback that no means is adopted to prevent the drawer from floating up, and therefore, it inevitably causes vertical play during the guide operation. When a restraining member is provided, there is a problem in that it is troublesome to adjust the vertical position of the restraining member in order to suppress rattling to the extent that opening/closing operations are not stiff.

The present invention has been made in order to solve the above-mentioned difficulties, and an object of the present invention is to provide a drawer device in which the prevention of rattling of the drawer can be easily adjusted.

As a means distantly related to that purpose, the drawer device of the present invention includes a swinging support plate, whose front and rear ends swing up and down about a support shaft in the middle part, which is pivotally supported on the slider. A guide roller that comes into contact with the guide surface of the guide groove is pivotally supported at one swing end of the support plate, and a swing position adjustment means is formed at the other swing end of the swing support plate. It is characterized by being

Hereinafter, the present invention will be explained based on the illustrated embodiments.

As shown in FIGS. 1 to 9, the drawer device of the embodiment is formed of a side plate of a drawer 1 (in the illustration, a right side plate 2) and a vertical plate 3 of the main body of the furniture, etc., which is in contact with the side plate 2. and
Specifically, a guide groove 2a with a U-shaped cross section that runs all the way through in the front-rear direction is bored at the middle height of the outer surface of the side plate 2, and a guide groove 2a made of low-friction resin is formed at the rear of the guide groove 2a. A sliding contact piece 4 having a cross-sectional shape is spread over the upper surface of the guide i2a and the upper side surface of the gap 2a.

On the other hand, the height of the opposing surface of the vertical plate 3 that is in contact with the groove 2a is as follows:
A cross-sectional or U-shaped sliding rod 5 made of metal or hard resin is mounted with the upper plate 5b facing upward by mounting screws 6 inserted into mounting holes 5a at multiple locations (four locations in the illustration). fixed horizontally.

Therefore, the lower edge of the sliding rod 5 near its front end is cut off in a stepped manner, the front end of the upper plate 5b is cut off, and a pivot shaft is installed inward at the front end of the sliding rod 5. A tip guide roller 8 made of resin is pivotally attached to 7, and both tops of the roller 8 are located at a position slightly higher than the upper surface of the upper plate 5b.

In addition, a support shaft 9 is planted inward at the front part of the slide 5, and an inward collar 5d is formed by cutting and raising a window hole 5c near the center of the support shaft 9. A cutout 5e is formed in the upper plate 5b above the cage.

Furthermore, a swinging support plate 10 sandwiched between spacers 14 and 15 (see FIG. 6) on both sides is pivotally attached to the support shaft 9, and a pivot 11 implanted in the front part of the support plate 10 is pivotally attached to the support shaft 9. An intermediate guide roller 12 made of resin is pivotally attached to the support plate 10, and an inward flange 10a is formed at the rear of the support plate 10.
An adjusting screw 13 serving as a swing position adjusting means is screwed into the screw hole drilled in a, and the lower end of the screw 13 is in contact with the upper surface of the raised collar 5d.

Therefore, in the state shown in FIG. 7 (side sectional view taken along line A-A in FIG. 1) where the drawer 1 is pushed into the main body of furniture, etc., the top surface of the guide groove 2a of the drawer 1 is in contact with the tip guide roller 8. It is placed and supported by the sliding rod 5 at two places, the tops and the sliding contact piece 4, and the lower surface of the guide groove 2a is prevented from floating by the sliding rod 5 at the localization of the intermediate guide rollers 12.

In the drawer device of the embodiment configured as described above, the side plate 2 is guided and supported by the sliding rod 5 by being held at three points by the guide rollers 8 and 12 and the sliding contact piece 4, so that the guide of the drawer 1 is easily controlled. There is no vertical wobbling during operation, and the drawer 1 can be opened and closed with a slight operating force.

In addition, if the operating load on the drawer 1 becomes stiff due to deformation of the guide groove 2a or the deformation of the slider 5 over time, or conversely if there is wobbling in the vertical direction, pull out the drawer 1. Since the tool can be inserted into the adjustment screw 13 from above the sliding rod 5 through the upper plate notch 5e, the localization of the intermediate guide roller 12 can be adjusted by simply tightening and loosening the adjustment screw 13. Correct it so that it lightly touches the bottom surface of guide i2a, thereby placing the operating load in a good condition,
Moreover, it is possible to eliminate looseness during guide operation.

In addition, in the configuration of the above-mentioned embodiment, the sliding rod 5 is replaced by the vertical plate 3.
However, the same effect can be obtained by attaching the slider to the side plate of the drawer and drilling a guide groove in the vertical plate of the main body.

In addition, the adjusting means for adjusting and moving the vertical position of the intermediate guide roller 12 may have another suitable structure instead of the above-mentioned structure, for example, as shown in FIGS. Similarly, an intermediate guide roller 12 is attached to the front part of the swing support plate 16 which is pivotally connected to the support shaft 9 of the support plate 1.
The eccentric cam wheel 18 is attached to the cam shaft 17 installed in the rear part of the cam shaft 17 with appropriate rotational friction, and the cam wheel 18
If the bottom circumference of is made into a structure where it is cut and raised and abuts against the collar 5d,
Adjustments similar to those described above can be made by inserting a tool such as a bench into the notch 19 of the upper plate 5b and turning the cam wheel 18.

As described above, according to the drawer device according to the present invention,
By vertically adjusting the adjustment means provided at one swinging end of the swinging support plate 10, which swings around the support shaft 9 in the intermediate portion, with respect to the immovable inward flange 5d, the guide provided at the other swinging end is adjusted. Since the guide roller 12 is configured to move and adjust the rollers 12 up and down and guide the guide grooves and slides between the drawer and the side plate of the furniture back and forth, if there is any wobbling in the guiding operation. By finely adjusting the adjustment means above,
The above-mentioned rattling can be suppressed by easy and simple fine adjustment based on the lever principle, and this has the effect of improving the operability and maintainability of the drawer device.
