Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a stopper device for a sliding door that opens and closes the opening of, for example, a large commercial refrigerator, freezer, or clean room.

Prior art and its problems As shown in FIG.
4 via a hanger 45, and the hanger
A slit 49 extending in the longitudinal direction of the bottom wall 48 of the rail 44 is provided, and the upper end of the hanger 45 is inserted into the hanger rail 44 by being inserted through the slit 49. A stopper device is provided at the end of the hanger rail 44. 46 is provided, and a stopper device 46 is provided.
As shown in detail in FIG. 4, holes 51 are formed in both side walls 50 of the slide rail 44.
The bolt 52 passed through the
It consists of a nut 53 fitted into the screw of
It is known that the upper ends of the two are in contact with each other. By the way, when the width dimension of the sliding door 41 changes or when the mounting position of the rail 44 changes, the position of the stopper device 46 must be changed in order to adjust the degree of opening of the sliding door 41. In this case, the hole 51 through which the bolt 52 is inserted must be re-drilled in the rail 44,
Not only is this work cumbersome, but there is also the problem that the position of the stopper device 46 cannot be finely adjusted.

The purpose of this invention is to provide a stopper device for a sliding door that solves the above-mentioned problems.

Means for solving the problem The sliding door stopper device according to this invention is
a rectangular cylindrical hanger rail having a slit extending in its longitudinal direction on the bottom wall; a hanger that is inserted through the slit so that its upper end enters the hanger rail and a slide door is attached to its lower end;
In a sliding door stopper device that is provided on a hanger rail and has a stopper that the upper end of the hanger abuts, the stopper is placed on the bottom wall of the hanger rail so as to span the upper surface of both edges of the slit, and A backing plate is placed on the wall so as to span the lower surface of both edges, a bolt insertion hole is drilled at a position corresponding to the slit in the backing plate, and a nut is fixed to the stopper so that the screw hole corresponds to the bolt insertion hole. The bolt is inserted through the bolt insertion hole and the slit, and is screwed into the nut.

Embodiment An embodiment of this invention will now be described with reference to FIGS. 1 and 2.

The sliding door 11 opens and closes the opening 13 of the refrigerator 12, and is suspended from a hanger rail 14 via a hanger 15. A stopper device 16 is provided on the hanger rail 14. The hanger rail 14 has a vertically long rectangular square tube shape in cross section, and is attached to the refrigerator 12 with a fixing fitting 17. Hanga Rail 14
A slit 19 is provided at the widthwise center of the bottom wall 18 and extends in the length direction of the bottom wall 18.
Two hangers 15 are attached to the roller support member 20 housed in the rail 14 and two to each end of the roller support member 20 in the door movement direction, and are attached to the bottom wall 1.
8 slits 19; four rollers 21 received at both edges; a hanging bar 22 whose upper end is fixed to the roller support member 20 and whose mid-length is inserted through the slit 1; It consists of a hinge 32 interposed between the lower end of the holding bar 22 and the slide door 11 and capable of swinging the slide door 11.

The stopper device 16 includes a stopper 24 placed on the bottom wall 18 of the hanger rail 14 so as to straddle the upper surface of both edges of the slit 19, and a stopper 24 placed on the bottom wall 18 of the hanger rail 14 so as to straddle the top surface of both edges of the slit 19.
A backing plate 26 is placed on the lower surface of both edges and has a bolt insertion hole 25 at a position corresponding to the slit 19, and a stopper 24 is placed so that the screw hole 27 corresponds to the bolt insertion hole 25. The fixed nut 28 and the bolt 2 inserted from the lower side of the backing plate 26 into the bolt insertion hole 25 and the slit 19 and screwed into the nut 28
It consists of 9. The stoppers 24 are arranged opposite to each other and have lower edges received by both edges of the slit 19 on the upper surface of the bottom wall 18, and are stopped by the upper edges of both the plates 30, 31 and have one end. It consists of a shaped piece 33 having a hanging part 32 and a rectangular sponge rubber 35 fixed to the outer surface of the hanging part 32 of the shaped piece 33 with screws 34. Backing plate 26
has a rectangular flat plate shape with four sides approximately equal in size to the width of the rail 14. The nut 28 is fixed to the stopper 24 by welding to the top surface of the shaped piece 33. Screw hole 2 of nut 28
7, a bolt insertion hole 36 is also formed in the shaped piece 33.

Stoppers 24 are attached to the bottom wall 18 of the rail 14 from above and below.
With the nut 28 sandwiched between the backing plate 26 and
By screwing the bolt 29 into the
The stopper 24 and the backing plate 26 are tightened by the nut 28 and bolt 29, and the stopper 24 is fixed there. When the bolt 29 is loosened, the stopper 24
The bottom wall 18 together with the backing plate 26 and bolts 29
The stopper 24 can be moved freely along the upper surface, and by screwing in the bolt 29 again, the stopper 24 is fixed there.

Effects of the invention According to this invention, the stopper can be fixed to the bottom wall by screwing the bolt into the nut, and by loosening the bolt, the stopper can be moved freely. Adjustments can be made freely and easily.
