Description

TECHNICAL FIELD The present invention relates to a sliding door device for a refrigerator, a freezer, a storage, a warehouse, and the like.

2. Description of the Related Art As a slide door device of this type, for example, the actual open door 62-1
As disclosed in 89477 publication, with a sliding door,
The hanging metal fitting that suspends the slide door, the roller that is attached to the hanging metal fitting, and the slide door move between the open position and the closed position of the storage opening with a gap to the outer surface of the storage wall. It consists of rails that guide the rollers and pressing means that forcibly presses the slide door when closing the storage opening against the peripheral edge of the storage opening.A hinge is interposed between the slide door and the hanging bracket. By freely swinging the slide door in and out, it was attempted to prevent unreasonable force from acting on the mounting parts of the hanging bracket and the slide door when the slide door was forcibly pressed against the peripheral edge of the storage opening. Things are known.

Problems to be Solved by the Invention When closing the storage opening by the sliding door, the sliding door is not only moved inward and outward, but also the upward upward force is applied to the sliding door to cause the sliding door to jump and the rollers to move from the rails. May jump up.

Further, the swinging of the sliding door in the inward / outward direction by the hinge is a combination of horizontal movement and vertical movement in the inward / outward direction, and the horizontal movement and the vertical movement are associated with each other. Therefore, even if it is desired to move the sliding door only in the horizontal direction or only in the vertical direction, it has not been possible.

An object of the present invention is to provide a sliding door device for a refrigerator or the like that solves the above problems.

Means for Solving the Problems A slide door device of a refrigerator or the like according to the present invention is a slide door, a hanging metal fitting for hanging the slide door, a roller attached to the hanging metal fitting, and a slide door for opening the storage opening. A rail that guides the rollers so as to move with a gap between the position and the closed position with respect to the outer surface of the storage wall; and a pressing unit that forcibly presses the slide door at the storage position to the peripheral edge of the storage opening. In a sliding door device such as a refrigerator, the hanging metal fitting has a horizontal wall facing the upper end surface of the sliding door, the horizontal wall is provided with an elongated hole extending inward and outward, and the elongated hole is provided with a door hanging bolt. Between the upper end surface of the slide door and the lower surface of the horizontal wall, with the shaft part of the bolt being loosely screwed into the upper end surface of the slide door and the head of the bolt being engaged with the long hole edge from above. Characterized by forming a gap It is what

In the slide door device of the refrigerator according to the present invention, the horizontal wall is provided with an elongated hole extending inward and outward, and the shaft portion of the door suspension bolt is loosely penetrated into the elongated hole so that the threaded portion of the sliding door upper end surface. Since the gap is formed between the upper end surface of the sliding door and the lower surface of the horizontal wall with the head of the bolt engaged with the edge of the long hole from above, only the length of the long hole The sliding door can be moved inward and outward, and regardless of this, the sliding door can be moved up and down by the gap.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, the sliding door device is a refrigerator wall.
A slide door 14 that closes a storage opening 12 provided in 11 through a packing 13, two hanging fittings 15 that suspend the sliding door 14, and a roller 16 attached to each hanging fitting 15. , The sliding door 14 moves between the open position of the storage opening 12 and the closed position of the storage opening 12 with respect to the outer surface of the storage wall 11 with a moving roller 16
And a rail 17 for guiding. Also, sliding door
A pressing roller 18 is attached to the center of the upper end of 14, and a pressing rail 19 for guiding the pressing roller 18 is attached to the outer surface of the storage wall 11. The pressing rail 19 gradually approaches the storage wall 11 from the right to the left, and the roller 18 is pushed inward by the pressing rail 19 so that the slide door 14 at the storage position 12 closes the storage port 12. It is forcibly pressed against the peripheral portion, whereby the storage port 12 is sealed.

As shown in detail in FIG. 1, the upper frame member 21 of the slide door 14
A bolt hole 22 is provided in the. Plate-shaped female screw member 23
Is embedded under the upper frame member 21 in a state where the female screw 24 is matched with the bolt hole 22.

The hanging metal fitting 15 has an inward U-shaped cross section,
It includes a horizontal upper wall 31 and a lower wall 32, and a vertical intermediate wall 33 connecting the outer edge portions of the upper wall 31 and the lower wall 32 to each other. An L-shaped bracket 34 is attached to the upper wall 31 with bolts and nuts, and a horizontal support shaft of the roller 16 is attached to a vertical portion of the L-shaped bracket 34. At the center of the lower wall 32, there is a long hole that extends inward and outward.
35 is provided, through which the large diameter shaft portion 37 of the stepped bolt 36 is passed, and the small diameter screw portion 38 is screwed into the female screw 24 so that the edge portion of the female screw 24 abuts the step portion. A thrust washer 41 and a ball bearing 42 fitted on the shaft portion 37 are interposed between the head 39 of the bolt 36 and the lower wall 32.

A gap C is formed between the lower surface of the lower wall 32 of the hanging fitting 15 and the upper surface of the upper frame member 21 of the slide door 14 with the bolt 36 tightened.

The sliding door 14 is movable inward and outward relative to the hanging metal fitting 15 by the amount that the bolt 36 moves in the long hole 35. Further, the slide door 14 is vertically movable with respect to the hanging metal fitting 15 and can be swung inward and outward by the amount of the clearance C. Therefore, the sliding door 14 freely moves and is brought into close contact with the peripheral portion of the storage opening 12 without being restrained by the hanging metal fitting 15 when the door is closed.

The sliding door 14 is a "drop-in type", that is, the storage opening 12
In the open state, the lower end of the door 14 is at a level higher than the lower end of the storage wall 11, and when the storage opening 12 is closed, the lower end of the door 14 is at the same level as the lower end of the storage wall 11, and the slide door 14 and the hanging metal fitting 15 are When fixed like a conventional one, the door 14
The roller 16 may float from the rail 17 when closed, which is prevented by the gap C.

Effect of the Invention According to the present invention, the slide door can be moved inward and outward by the length of the long hole, and regardless of this, the slide door can be moved up and down by the amount of the gap. From
Even if an unreasonable force in the inward / outward direction and the up / down direction is applied to the slide door when the slide door is pressed against the peripheral edge of the storage opening, this can be prevented.
