Abstract

PURPOSE:To improve facility by increasing the opening sizes of a door and a container, by a method wherein the deep part of the upper side of stationary rails mounted on both sides of an inner box forms a plane, the front part of the rail forms a slope inclined upward, and a protrusion for check making contact with a rolling roller is formed on a part of the slope. CONSTITUTION:Rolling rollers 6 mounted to the tip of a pair of moving rails 6 mounted on an inner wall surface 7 of a drawer type door 5 are rolled in stationary rails 15. With the drawer type door 5 drawn, the rolling roller 8 is rolled over a horizontal plane 17 and a slope 18 of the stationary rail 15, and forced into contact with a protrusion 19 for check and rolling of the roller is checked. Since the rolling roller 8 is moved in a manner described above, the drawer type door 5 is inclined forward as it is drawn out, and is checked in an inclined-forward state in a manner that it is supported by means of the rolling roller 8 making contact with a slope 20 of the protrusion 19 for check and a stationary roller 10 making contact with a part of a lower end surface 12 of a moving rail 6. This constitution enables increase of an opening size (n), and facilitates taking in and out of foods, resulting in improvement of facility.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a refrigerator body having a pull-out door.

BACKGROUND OF THE INVENTION In recent years, refrigerators have come to be installed alongside sinks, cupboards, and the like. Therefore, the depth dimension is limited, and
They are becoming thinner.

A conventional example will be described below with reference to the drawings. Third
In Figures to Figures 5, 1 is the refrigerator main body. 2 is the outer box and 3 is the inner box. 4 is a heat insulating material filled between both boxes. Reference numeral 5 denotes a pull-out door that extends through the opening of the refrigerator body 1. 6 is a pair of movable rails attached to the inner wall surface 7 of the pull-out door 6. Reference numeral 8 denotes rolling rollers attached to both sides of the tip of the movable rail 6. Reference numeral 9 denotes fixed rails attached to both side walls of the inner box 3. Reference numeral 10 designates fixed rollers housed on both side walls of the front surface of the inner box 3. Reference numeral 11 denotes a storage container placed within the movable rail/L/e. 12 is a door that covers the opening of the refrigerator body 1.

In the pull-out door 5, rolling rollers 8 installed on both sides of the tip of a movable rail 6 roll on fixed rails 9 attached to both side walls of the inner box 3. The lower end surface 13 of the movable rail 6 slides on the fixed rollers 1° attached to both side walls of the movable rail 6, so that the movable rail 6 can be easily pulled out. 14 is a convex part for stopping it+lJ provided on a part of the lower end surface 13 of the movable tray/L'6,
The opening dimensions are regulated.

Problems to be Solved by Kanmei However, in the above configuration, since the depth l of the inner box 3 is shallow, the depth dimension of the storage container 11 is also inevitably shallow. Therefore, as shown in FIG. 4, the storage container 11 and the door 12
The problem was that the size of the container was small, it was not possible to store large foods, etc., and it was difficult to take out the number of items stored.

The present invention addresses the above-mentioned problems and provides a refrigerator in which the number of stored prizes and the like can be easily accessed even if the depth dimension is shallow.

Means for Solving the Problems In order to solve the above problems, the refrigerator of the present invention has the upper sides of the fixed rails installed on both sides of the inner box as a horizontal surface at the back, and the front side thereof as an inclined surface that slopes upward. A part of the inclined surface is provided with a stopping protrusion that comes into contact with the rolling roller.

Function: With the above configuration, the rolling roller attached to the tip of the movable rail of the pull-out door rolls on the inclined surface of the fixed rail as the pull-out door is pulled out in the 011 direction. For pull-out doors, refer to the previous section. Therefore, the opening between the door and the storage container becomes larger, making it easier to store and take out prizes, etc.

EXAMPLE Hereinafter, a refrigerator according to an embodiment of the present invention will be described with reference to the drawings, but the same configuration as the conventional one will be given the same reference numeral and detailed explanation thereof will be omitted.

In FIGS. 1 and 2, reference numeral 16 indicates fixed rails attached to both side walls of the inner box 3. Upper side 16 of fixed rail 16
has a horizontal surface 17 at the back and an inclined surface 18 inclined toward 0+1. Reference numeral 19 denotes a stopping protrusion provided on a part of the inclined surface 18, which comes into contact with the rolling roller. Reference numeral 2o denotes an inclined surface forming the restraining convex portion 19.

The configuration is as described above, and the operation will be explained next. A rolling roller 8 attached to the tip of a pair of movable rails 6 attached to the inner wall surface 7 of the pull-out door 6 is connected to a fixed seat/
Rolls within l/15. Further, the lower end surface 12 of the movable rail 6 slides on fixed rollers 10 attached to both sides of the front surface of the inner ti3. When the pull-out door 5 is pulled out, the rolling roller 8 rolls on the horizontal surface 17 and the inclined surface 18 of the fixed rail 16, and comes into contact with the stopping protrusion 19 to stop it.

Also, the lower end surface 13 of the movable rail lv6 is also t on the fixed roller 1o.
It will slide. As the rolling roller 8 performs the above-mentioned sharp movement, the pull-out door 6 tilts forward as it is pulled out, and the rolling roller 8 comes into contact with the inclined surface 20 of the stopping protrusion 19. , the movable rail lve is brought into contact with a fixed roller 10 that comes into contact with a part of the lower end surface 12 of the movable rail lve, and is stopped from tilting forward.

As mentioned above, according to the false axis example, even if the depth dimension of the inner box 3 is shallow, the door 1 is stopped because it remains tilted IJIJ.
2 and the storage container 11 can be made larger, making it easier to store and take out food, improving usability.

Furthermore, when the pull-out door 5 is pulled out, the pull-out door 6 tilts forward, its center of gravity falls on the front surface of the pull-out door s6, and it opens in one step. At this time, by making the contact surface of the rolling roller 8 of the stopping protrusion 19 the inclined surface 2o, the impact at the time of stopping is alleviated, and effects such as reduction of impact noise etc. can be achieved.

Effects of Yuanmei As described above, according to the present invention, the upper side of the fixed rail that shoulders the sliding surface of the rolling roller is installed on both side walls of the cold alt main body.
The inner part is a horizontal plane with a certain dimension, and the front part is an upwardly inclined plane, and a part of the inclined plane has a convex part t-W for restraint.As the drawer-type door is pulled out, the front side It leans forward and stops while leaning forward. Therefore, the opening size between the door and the storage container can be increased,
Effects such as making it easier to take out and store food and improving usability can be achieved.
