Description

Rotating tray for storage room that can be drawn out in a straight line}

The present invention relates to a rotating tray for a storage room that can be pulled out in a straight line. In detail, it is seated in an existing storage room to conveniently store items inside, allows easy removal of items deep inside, and allows items stored on both sides to be easily removed. This is about a rotating tray for a storage room that can be pulled out very conveniently by rotating the turntable.

In general, a storage room refers to a rectangular storage room such as a refrigerator, a microwave kitchen, or a storage cabinet for storing items.

As the industry develops, the usability value of storage rooms increases, and as well as configuring storage rooms for various purposes, research has been conducted on structures that allow for more convenient storage and withdrawal of items or food to be stored in the storage room.

However, until now, the tray for convenient storage and retrieval of items was developed to be integrated into the main body that constitutes the storage room, which resulted in a complicated configuration and the problem of not being easy to clean when dirt gets on the tray.

Recently developed trays have been developed to leave the existing storage as is, construct a separate tray, mount it inside the storage cabinet, and remove it for cleaning, seeking convenience in use.

Accordingly, if we look at the patent documents regarding the rotating tray for storage rooms that have been developed and implemented so far, they are as follows.

What has been developed and used so far is that the tray is installed integrally in the storage box, which makes the configuration complicated, and when dirt gets on the tray, it is difficult to clean, and especially when the storage room is wider on the left and right than the depth, the turntable cannot be rotated. There was a problem.

In order to solve this problem, recently, the tray that makes up the turntable has been constructed separately so that it can be attached and detached from the bottom of the cabinet. However, this is also a configuration in which a trajectory is formed on the base plate that makes up the tray and the turntable moves along the trajectory. This not only does not solve the problem of straight drawing of the table, but also causes the bearing that supports the tray to continuously rub along the track, damaging the track. In addition, a retainer that holds the bearing is required, which is one of the reasons for the increase in production costs.

Accordingly, the present invention forms at least three pairs of bearing coupling parts on the base plate constituting the tray, which have a flat bottom and vertical shaft coupling parts on both sides. The purpose is to prepare for the load by constructing an ample-type bearing that rolls with both ends supported at the shaft-bearing joint, and to enable the turntable to be pulled out straight in any rotation state, making it convenient to use. .

The present invention for achieving the above object is a rotating tray for a storage room, which includes a base plate configured with fixing means to be fixed to the floor of a storage room and a turntable configured to rotate by being coupled to the base plate, wherein the base plate is guided at the rear end. It constitutes a wall, and in the center, a guide long tool component is formed in a straight line forward and backward, combining a guide assembly with a coupling jaw integrally formed on the outer circumferential surface, and at least three pairs of bearing couplings constituting axle and bearing coupling parts on both sides are formed in a circumferential shape. and mounting the bearing; The turntable consists of a rectangular shape with both sides of a rectangle longer than the front and back lengths in an arc shape, a border to accommodate items, and an axis pin with a head at the center of the bottom to prevent separation; An axis pin is coupled to the guide hole of the base plate to form a rotating tray for a storage room capable of straight-line withdrawal so that the turntable is supported on a bearing and performs straight-line withdrawal and rotation.

Here, the guide assembly coupled to the base plate forms a coupling jaw on the outer periphery, and is integrally composed of a coupling hole equipped with a gripping finger with tension at the rear end of the guide long hole, and the bearing coupling portion formed on both sides of the bearing coupling portion The bottom surface and the side wall are formed horizontal and vertical so that the bearing part of the bearing is in line contact. The bearing is composed of an ampoule shape with bearing parts formed on both ends, and the ends of the bearing part are formed in a narrow cone shape to reduce friction. Constructs a rotating tray for storage room that allows for minimal straight withdrawal.

In the present invention described above, at least three pairs of bearing coupling parts having a flat bottom and vertical shaft coupling parts on both sides are formed on the base plate constituting the tray. The bearings on both sides are supported and rolled in the shaft-bearing joint section to prepare for the load by rolling in linear contact between the turntable and the bearing. The turntable can be pulled out straight in any rotation state, making it convenient to use and manufactured. It is a novel invention that has the effect of being inexpensive.
