Description

[Detailed description of the invention] The present invention relates to a pull-out device for use in refrigerators, kitchen furniture, etc., in which a door that covers an opening inside the refrigerator is pulled out using a rail, and when the door is closed. The present invention relates to a structure that ensures a seal between the door and the opening.

Conventionally, the rail has a drawback in that it is difficult to maintain levelness due to dimensional variations during manufacture, and this results in insufficient sealing between the door and the opening.

Furthermore, the rail leveling mechanism has been complicated and expensive, making it difficult to put it to practical use.

The present invention aims to eliminate these drawbacks by using an inexpensive and simple mechanism.

An embodiment of the present invention adopted in a refrigerator will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a refrigerator body, which has an opening 2 on the front surface, and an inner box 5 having a side wall 3 and a back wall 4.

Reference numeral 6 denotes a door that covers the opening 2 in an openable and closable manner, and has a gasket 7 around the entire circumference so as to come into contact with the opening 2 when the door is closed.

8 is a pair of rails provided opposite to each other on the side wall portion 3;
A support rail 9 is attached to the side wall portion 3 with screws 9a and 9b, and a sliding rail 10 is provided on the door 6 so as to correspond to the support rail 9.

The support rail 9 is approximately U-shaped and has an elongated hole 11 and a roller 12 at the front, a mounting section 14 having a round hole 13 at the rear, and an extension section 15 extending horizontally from above and below.

9a and 9b are connected to the rail 9 through the round hole 13 and the elongated hole 11, respectively.
This is a screw that fastens the.

Further, the sliding rail 10 has a substantially horizontal support part 16, a vertical piece 17 extending downward from the support part 16, and a roller 18 at the rear.

The roller 18 is a substantially U-shaped extension 15 of the support rail 9.
The supporting portion 16 of the slide rail 10 is slidably placed on the roller 12 and fixed therebetween.

19 has different dimensions from the threaded part 20 to each side (
A<B<C<D<E<F) A bolt having a polygonal head 21, the head 21 is brought into contact with the lower surface of the extension part 15 near the long hole 11 of the support rail 9, and the threaded part 20 is rotatably attached to the side wall part 3.

22 is a storage container placed on the sliding rail 10.

In this configuration, if the support rail 9 is not level due to variations in manufacturing dimensions or installation, or if the levelness shifts after long-term use, the screws 9a and 9b should be removed once. Slightly loosened extension part 15
The front of the support rail 9 can be easily raised and lowered by rotating the head 21 of the bolt 19 that is in contact with the bolt 19, and the horizontality can be adjusted. It is possible to improve or maintain the sealing performance of the 7 parts.

Further, since the head 21 is polygonal, rotation of the head 21 can be prevented after adjustment, and the horizontality will not be disturbed.

Furthermore, leveling can be adjusted using only the bolts 19, making it very inexpensive.

As described above, the present invention provides a box such as an inner box having an opening on the front side and a side wall, and a pair of rails facing each other on the side wall, and the opening is opened and closed on the rail. In the case where the door is slidably arranged, the head of a bolt having a polygonal head with different dimensions from the center of the screw is brought into contact with the lower surface of either the front or rear of the rail. At the same time, the screw part is rotatably attached to the side wall part so that the horizontality of the rail can be adjusted.The polygonal head allows the horizontality to be freely adjusted and improves the sealing performance of the door. In addition to being able to measure the level, it also prevents the leveling from going out of order.

In addition, the horizontality can be adjusted using only bolts, and it is very inexpensive and has extremely high practical effects.
