Abstract
The present invention relates to a roller assembly for a storage device in which noise can be prevented from being slippery, smooth rolling is possible, and peeling of a portion made of a rubber material can be prevented.
To achieve this object, the present invention provides a method of manufacturing a honeycomb structure including a cylindrical body portion opened to the front and rear sides, a partitioned portion formed so as to block the inner circumferential surface of the body portion and having a through hole formed on the central portion thereof and an expanded end formed to extend outwardly from the outer peripheral surface of the body portion, absence; A contact member made of a rubber material or a silicone material and being injection-molded so as to collectively surround the outer ends of the expanding end and the body end of the rolling member; And a fastening part that is fastened to the accommodating device while the rolling member is rotatably installed. The roller assembly for a storage device is provided.
Description
BACKGROUND OF THE
BACKGROUND ART [0002] Generally, a storage unit such as a vegetable box of a refrigerator is provided with a roller assembly for smooth movement of the storage unit. The conventional roller assembly includes a shaft coupled to the refrigerator body, And a roller.
In particular, in recent years, various types of roller assemblies have been provided in which the contact area between the rollers and the shaft can be minimized so that the rolling of the rollers can be more smoothly performed. In this regard, in the registration patent application No. 10-0908659, 20-0452543 and the like.
However, in the above-described conventional roller assembly, the roller is formed of polyoxymethylene (POM) material, so that the roller and the counterpart (for example, a vegetable box or a rack on which a shelf is placed) There is a problem that noise is generated due to contact, and excessive withdrawing of the storage device due to a slipping phenomenon occurs.
Conventionally, there has been an effort to minimize the slip phenomenon by joining a rubber material or an O-ring made of silicone to the outer circumferential surface of the roller. However, The width of the roller is designed to be a width considering the weight of the receiving device. However, when the receiving device is operated, the weight is biased to both sides of the roller, Its application has not been made because of its noise and damage.
Further, as the weight of the accommodating device becomes larger, the above-mentioned O-ring has a problem that the frictional force with the opponent increases, and the O-ring can not be smoothly operated and easily peeled off from the roller.
Of course, the entire roller may be formed of a rubber material or a silicon material. However, since the size of the shaft supporting the roller is relatively smaller than the size of the roller, a load of the storage device is provided to the roller The roller may not be smoothly moved due to the tilting of the roller from the shaft. In addition, since the roller is easily peeled off from the shaft, there is a problem of operational reliability.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a method for preventing noise and slip phenomenon, And a roller assembly for a storage device according to the present invention.
In order to achieve the above object, according to the present invention, there is provided a roller assembly for a storage device, comprising: a cylindrical body which is open to the front and rear; a partition which is formed to block the inner circumferential surface of the body and has a through- A rolling member having unified extension ends formed so as to be integral with each other; A contact member made of a rubber material or a silicone material and being injection-molded so as to collectively surround the outer ends of the expanding end and the body end of the rolling member; And a fastening part which is fastened to the accommodating device while the rolling member is rotatably installed.
In this case, a plurality of communication slits are formed in the extending end of the rolling member so as to pass through in the front-rear direction.
Further, the outer peripheral edge of the expanding end forming the rolling member is rounded.
Further, a receiving groove is formed on the front side and the rear side outer wall surface of the partitioning end forming the rolling member.
Further, the fastening portion may include a holder that forms a portion coupled to the accommodating device, and a shaft that forms a portion coupled to the rolling member, and the holder and the shaft are separately provided and detachably coupled to each other, And the holder and the shaft are formed as a single body.
As described above, the roller assembly of the present invention prevents the stress concentration on a specific portion from being concentrated due to the contact member made of a rubber material forming the entire circumferential surface of the roller assembly, so that the roller assembly is prevented from being tilted toward one side Therefore, it is possible to prevent the generation of the uneven wear, the breakage of the shaft, and the breakage of the holder.
Furthermore, the contact member can minimize the contact noise with the rail during the rolling operation of the roller assembly, and also has an effect that excessive withdrawal of the storage device due to slipping can be prevented.
In addition, the contact member of the roller assembly of the present invention is integrally formed with the rolling member by double injection, and also has the effect of preventing the roller assembly from being peeled off during the rolling operation by the plurality of communication slits formed in the extended end.
Further, in the roller assembly of the present invention, among the respective parts of the rolling member, a receiving groove for minimizing the contact area and temporarily accommodating the lubricant is formed at a portion in contact with the shaft and the holder, and the receiving groove is closed with a Teflon sheet So that the smooth rolling motion can be always performed.
