Description

[Detailed description of the invention] <Industrial field of application> The present invention is a revolving shelf in a corner cabinet for a kitchen, specifically, a back plate of a support fitting formed in a U-shape on the side is used as a shelf body and a cabinet, respectively. installation,
The present invention relates to a device in which the upper and lower plates of these supporting metal fittings are stacked on top of each other, and both are pivoted by a pivot perpendicular to both the upper and lower plates to rotatably support the shelf body in a cabinet.

<Prior Art> Conventionally, as disclosed in Japanese Utility Model Publication No. 55-45792, a rotary shelf for this type of corner cabinet is provided by screwing a screw onto the upper surface of one end of the lower plate of the cabinet side supporting metal fitting. There is one in which the rotation range of the shelf is regulated by bringing the lower plate of the shelf-side support fitting into contact with the head of the shelf.

<Problem to be solved by the invention> However, in such conventional rotating shelves in corner cabinets, the entire weight of the shelf body is concentrated on the heads of the screws via the support fittings, so Not only does the impact at the time of contact be large, but when used over a long period of time, the head of the screw gradually wears out due to the weight of the revolving shelf and its stored items, and as this wear increases, the lower plate of the shelf side support bracket becomes damaged. There are problems in that it may take some force to pull out the rotary shelf because it rides on the head of the screw, and if the head of the screw becomes severely worn, it may no longer function as a stopper.

In addition, if the drawer direction of the rotating shelf is reversed due to the arrangement of the corner cabinet, a new supporting bracket with completely opposite left and right sides, with screws screwed onto the top surface of the other end of the bottom plate, will be required. There is also the issue of becoming.

In view of the conventional circumstances, the present invention aims to disperse the impact when the stopper comes into contact with the stopper, and to make it possible to share the rotary shelf regardless of the direction in which it is pulled out.

<Means for solving the problem> The technical means taken by the present invention to solve the above problem is to form one corner of the tip end side of the upper plate and lower plate of one of the supporting metal fittings into a 1/4 cut circular shape. , the length from the center of the pivot to the arcuate portion is shorter than the length to the other back plate, and the portions from this arcuate portion to two consecutive corners are each formed in a straight line, and both of these straight portions forms an obtuse angle and contacts the other back plate 1
It is characterized by comprising a pair of stoppers.

<Operation> According to the above-mentioned technical means, the present invention rotates the other back plate along the circular arc portion and brings the other back plate into surface contact with two continuous linear stoppers, thereby preventing the rotation of the back plate. The drawing direction is reversed by gradually stopping the drawer while providing a buffer, and by arranging the upper plate and the lower plate, on which the arcuate portion and both stoppers are formed, upside down.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG. 1, the corner cabinet B ₁ is connected to several other cabinets B ₂ ,
B ₃ ... is arranged in a plane shape so that the shelf body A of the rotating shelf can be pulled out by rotating clockwise.
It is equipped with stoppers 29 and 31.

The shelf body A of the rotating shelf includes a semicircular mesh plate 1 formed by assembling metal wires, and a plurality of standing wire rods 2 around the mesh plate 1 by bending the metal wires in the same shape as the outer periphery of the mesh plate 1. It is formed into a net shelf consisting of fall prevention walls 3 connected to each other.

This shelf A has a circular arc portion 4 on the front side and a straight portion 5.
is on the back side, and on the back side of the fall prevention wall 3, there are two standing wire rods 2a, 2b located at both left and right ends.
A cushioning body 6 made of rubber or synthetic resin and formed into a tubular shape is attached to the outer peripheral surface of the rubber or synthetic resin so as to protrude outward, and a reinforcing plate 7 of an appropriate width is attached to the central part in the longitudinal direction. A shelf-side support fitting 8 is attached from above 7.

The shelf-side support fitting 8 is formed into a U-shape when viewed from the side by a back plate 9 and an upper plate 10 and a lower plate 11 that are continuously formed on both upper and lower ends of the back plate and extend forward at right angles to the back plate 9. The back plate 9 has stepped portions 12 on both the upper and lower ends, making the width slightly narrower. The rotating shafts 13 are formed to have the same width as the parts, and are provided with rotating shafts 13 that project downward at the centers of the width directions.

Further, the upper plate 10 and the lower plate 11 are connected to a rotating shaft 13.
The front part of the shaft is formed in an arc shape centered on the shaft.

Then, this shelf body side support fitting 8 is attached and fixed to the shelf body A by bringing the back surface of the back plate 9 into contact with the reinforcing plate 7,
Corner cabinet B ₁ with rotating shaft 13 described later
It fits into the bearing hole 15 of the cabinet side support fitting 14 fixed to.

The above-mentioned shelf-side support fittings 8 are fixed to the shelf A using bolts and nuts 1 through mounting holes 16 drilled in the back plate 9 of the shelf-side support fittings 8 and the reinforcing plate 7 of the shelf A, respectively.

Corner cabinet B ₁ has the front half and
It is formed into a box shape with the entire top surface open, and has a length slightly longer than the length of the shelf body A and a depth slightly wider than half the length of the shelf body A. is provided with a door 19 for opening and closing the section.

The side surface located at the corner and opened and closed by the door 19 and the closed front portion 20 are in contact with the adjacent cabinets B ₂ and B ₃ . Also,
The corner cabinet B ₁ has a partition post 21 erected at the center in the left-right direction of the front end, that is, at the boundary between the closed part 20 of the front of the corner cabinet B ₁ and the part 18 opened and closed by the door 19. and
A cabinet side support fitting 14 is attached to this partition column 21.
is installed.

The cabinet side support fitting 14 has a back plate 22 and
The upper plate 23 and the lower plate 24 extend forward at right angles to the back plate 22 at both upper and lower ends, forming a U-shape when viewed from the side. A side plate 25 is formed that extends rearward at right angles to the plate 22.

The back plate 22 has stepped portions 26 at both upper and lower ends on the side plate 25 side.
The upper plate 23 and the lower plate 24 are slightly longer than the upper plate 10 and the lower plate 11 of the shelf side support fitting 8, continuing from the narrowed width part. stand out.

The upper plate and lower plate 24 of this cabinet side support fitting 14 are formed into a substantially square shape, and a bearing hole 15 having a larger diameter than the rotating shaft 13 of the shelf side support fitting 8 is bored in the center thereof. A synthetic resin bush 27 is fitted into the bearing hole 15.

The synthetic resin bush 27 has an inner diameter slightly larger than the diameter of the rotating shaft 13 and an outer diameter that is the same as the diameter of the bearing hole 15. The synthetic resin bush 27 is integrally provided with a flange 28 at one end of the tube.
Mount the cabinet side support bracket 14 with the side facing up.
The upper plate 23 and the lower plate 24 are fitted into the bearing hole 15 from above.

Further, in the front part of the upper plate 23 and lower plate 24 of the cabinet side support fitting 14, the corner 29 on the same side with respect to the side plate 25 is at a right angle, and the corner 30 on the opposite side with respect to the side plate 25 is at right angles. It is formed in a 1/4 cut circular shape with the bearing hole 15 as the center and the radius is the length from the center of the bearing hole 15 to the front end, and
At the rear, a corner 31 on the opposite side of the side plate 25 is formed at a right angle or slightly smaller, and the shelf side support fitting 8 extends from the center of the bearing hole 15 to the front end.
The length is slightly longer than or equal to the length from the center of the rotating shaft 13 to the front end of the upper plate 10 and lower plate 11.

Thus, the cabinet side support fitting 14 has the back plate 22 and the side plates 25 in contact with the back and side surfaces of the partition column 21, respectively, and is inserted through the through holes 32 bored in both the plates 22 and 25. Attach the partition pillar 21 with wood screws 33, etc.
The upper plate 10 and lower plate 11 of the shelf side support fitting 8 are stacked on the upper plate 23 and the lower plate 24 from above, and the rotating shaft 13 of the shelf side support fitting 8 is inserted into the bearing hole 15 through the bush 27. Fit together.

Next, FIGS. 5 and 6 show another embodiment in which a corner cabinet B ₁ is arranged in a planar manner together with several other cabinets B ₂ , B ₃ . . . The body A can be pulled out by rotating it counterclockwise.

In this case, the cabinet side support fitting 14 is attached to the partitioning post 21 upside down, and the lower plate 24
Stack the upper plate 10 and lower plate 11 of the shelf-side support fittings 9 on the upper plate 23 from above, respectively, and insert the rotating shaft 13 into the bearing hole 15.
are fitted through the bushing 27.

In this way, the shelf A is rotatably mounted inside the corner cabinet B ₁ , and by rotating it, approximately half of it is pulled out to the outside of the corner cabinet B ₁ through the opening 18 where the door 19 is opened. From this state, it is rotated in the opposite direction and is housed in the cabinet _B1 .

When pulled out from the corner cabinet B ₁ , the back plate 9 of the shelf-side support fitting 8 extends along the 1/4-cut circular corner 30 formed on the top plate 23 of the cabinet-side support fitting 14 . It rotates, but when it rotates about 90 degrees from the stored state, the back plate 9 collides with the rear corner 31, and the rotation is blocked.

At this time, since the buffer bodies 6 are attached to both the left and right ends of the back surface of the shelf A so as to protrude outward, even if the door 19 is opened halfway, the back surface of the door 19 will not be affected. Collisions always occur through the buffer 6, so no damage is caused and the noise is low.

On the other hand, on the other hand, shelf A is corner cabinet B ₁
When stored inside, the shelf side support fittings 1
4 collides with a right-angled corner 29 formed in the front part of the upper plate 23, and its rotation is prevented.

That is, the upper plate 23 of the cabinet side support fitting 14
The two corner portions 29 and 31 formed in the shelf body A respectively constitute a stopper that restricts the rotation of the shelf body A.

Since both stoppers 29 and 31 are constituted by a straight line part continuous to the arcuate end of the 1/4 cut circular corner part 30, the rotation of the shelf A is not abruptly stopped, but is stopped while buffering the impact. You can force it. It goes without saying that the same function can be achieved even if stoppers 29 and 31 are formed at the top and bottom ends of the upper plate 10 and lower plate 11 of the shelf support fitting 8, respectively, as shown in FIG.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

The other back plate rotates along the arc portion and comes into surface contact with two continuous linear stoppers, thereby buffering the rotation of the back plate and gradually stopping it. By arranging the upper and lower plates on which the stoppers are formed upside down, the pull-out direction is reversed, which disperses the impact when the stoppers come into contact, and makes it possible to share the rotating shelf regardless of the pull-out direction. be able to.

Therefore, compared to conventional models in which the impact is concentrated when the stopper contacts the stopper, the stopper has less wear and can reliably perform its function over a long period of time. There is no need for supporting metal fittings that are completely opposite on the left and right, as is the case with conventional products, making it easier to use and easier to manage inventory.
