1 is a combined state diagram of a shelf height adjusting device for a refrigerator according to the present invention, Figure 2 is an exploded perspective view of the shelf height adjusting device for a refrigerator according to the present invention, Figure 3 and Figure 4 is a shelf height for a refrigerator according to the present invention As an operation state diagram of the adjusting device will be described together for convenience of description.

As illustrated, the shelf height adjusting device 1 for a refrigerator according to the present invention is fixed to an inner wall of a refrigerating chamber (not shown) or a freezing chamber (not shown), and fixed shafts 11 and 12 that face vertically about a center thereof are disposed 12. A fixed frame 10 having a); A moving frame 30 installed in front of the fixed frame 10 and vertically moved together with the shelf 20; A rotating rod (40) connected to the moving frame (30), the spirals of the outer circumferential surface of which are formed in opposite directions with respect to the center thereof and rotatably installed in a symmetrical manner; And a pair of first and second horizontal moving members 50 and 51 which are screwed to the spiral of the outer circumferential surface of the rotating rod 40 and horizontally move in opposite directions by the rotation of the rotating rod 40. ; One side is connected to the first and second horizontal moving members 50 and 51, respectively, and the other side is fixed to the fixing shafts 11 and 12 opposite to the fixing frame, respectively. First and second connecting bars 52 which allow the pivoting rod 50 to move up and down by opposing horizontal movement of the first and second horizontal moving members 50 and 51 by rotation in opposite directions. 53).

In addition, the shelf height adjustment device 1 for the refrigerator according to the present invention is further provided with a support frame 60 to protrude and project the guide jaw 61 to the upper both sides so that the handle shaft 62 is rotatable to the lower center. After passing through the installation, both rear sides are screwed to both sides of the moving frame 30, respectively. Therefore, the moving frame 30, the support frame 60 and the shelf 20 can all move vertically up and down together.

And, the shelf 20 has a guide groove 21 is formed to be guided by being guided to the guide jaw 61 of the support frame 60 on both sides of the lower side, and the locking jaw (like the upper upper side) 22) is bent and extruded.

In addition, the height adjustment handle 63 is coupled to the front end of the handle shaft 62 so as to rotate the user, the driving gear 64 is inserted into the rear end. Therefore, the rotational force is transmitted to the driven gear 41 engaged thereto through the motive gear 64, whereby the spirals of the outer circumferential surface of the rotating rod 40 in the form of a double helical gear are centered opposite each other. It is formed to be symmetrically rotatable.

That is, the rotating rod 40 rotatably connected to the moving frame 30 is formed with a spiral (not shown in the figure) on its outer circumferential surface, and the shape of the spiral is a male screw shape and symmetrical with each other on both sides of the center portion. It consists of two left and right helix in the opposite direction to achieve a mutually symmetrical rotation by the operation of the height adjustment handle (63). Since this symmetrical rotating rod is widely known, a detailed description thereof will be omitted.

Here, the fixing frame 10 is fixed to the guide angle 70 integrally coupled to the inner wall of the refrigerator compartment or the freezer compartment (not shown) of the refrigerator via the fixing bracket 16.

The pair of first and second horizontal moving members 50 and 51 are extrapolated to left and right spirals of the rotating rod 40 and are horizontally movable in opposite directions according to the rotation of the rotating rod 40. This will be described in more detail, and female threads are formed on the inner surfaces of the first horizontal moving member 50 and the second horizontal moving member 51 to be screwed with a spiral (male screw) formed on the outer surface of the rotating rod 40. These screw coupling method is that when one of the horizontal moving member is coupled to the rotating rod 40 and the left screw, the other one is coupled to the right screw and the rotating rod 40 rotates, so that the pair of horizontal moving members are opposite to each other. In other words, they move toward or away from each other.

One side of the first and second connection bars 52 and 53 is connected to the first and second horizontal moving members 50 and 51, respectively, and the other side of the fixing shaft 10 is opposite to the fixing frame 10. (11) (12) of the first and second horizontal moving members (50, 51) of the first and second horizontal moving members 50 are fixed in a staggered form (" X " shape), respectively, by rotations of the rotating rods 40 in opposite directions. The moving frame 30 moves up and down with the pivoting rod 40 by the horizontal movements facing each other.

Here, the first and second connecting bars 52 and 53 and the first and second horizontal moving members 50 and 51 and the stationary shafts 11 and 12 opposing the stationary frame 10 and The coupling relationship can be fixed directly, but a structure that can be rotatably coupled by a pin or the like can also be used.

Referring to the operation of the shelf height adjustment device for a refrigerator according to the present invention configured as described above are as follows.

First, when the user rotates the height adjustment handle 63, as shown in Figs. 3 and 4, the primary gear 64 of the handle shaft 62 is rotated integrally to rotate the rotating rod 40, the first And the second horizontal moving members 50 and 51 are symmetrically moved left and right.

3, when the position of the shelf 20 is to be lowered, the height adjusting handle 63 is rotated in one direction so that the first horizontal moving member 50 and the second horizontal moving member 51 are rotated. In order to move in a direction away from each other, and conversely to increase the position of the shelf 20, as shown in Figure 4, by rotating the height adjusting handle 63 in the opposite direction to the first horizontal moving member ( What is necessary is just to make 50 and the 2nd horizontal moving members 51 move to mutually close directions.

5 and 6 is an operating state diagram of the shelf height adjustment device for a refrigerator according to another embodiment of the present invention, by forming only one connection bar 53, one side is symmetric about the center of the rotating rod 40 It is connected to one horizontal moving member 50 which is horizontally coupled to only one of the spirals and the other side is fixed to one of the two fixed shafts of the two fixed shafts of the fixed frame 10 to the rotating shaft It is substantially the same as FIG. 1 except for a structure in which the pivoting rod is moved up and down by the horizontal movement of the horizontal movable member 50 by the rotation of the spiral in the opposite directions of the spirally symmetrically formed about the center of the rod. Therefore, further description will be omitted. That is, even one connection bar can be used to move up and down while sufficiently supporting the shelf when using a material such as steel having considerable rigidity, which has the advantage of further simplifying the structure.

As described above, according to the shelf height adjustment cabinet for a refrigerator according to the present invention, the installation height of these shelves according to the size or height of the food stored on each shelf in the freezer or refrigerator compartment together with the handle operation of the double helical gear ( The rotating rod in the form of a double helical gear has an effect that can be adjusted precisely and easily.

Although the present invention has been described in detail with reference to preferred embodiments according to the present invention, this is only for illustrating the present invention and is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the scope of the present invention. It should be noted that this is possible as well as this is also within the scope of the present invention.
