Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a door hanging tool for a sliding door used, for example, in a prefabricated refrigerator or a warehouse.

BACKGROUND ART A conventional door hanging device, as shown in FIGS. 4 and 5, for example, has a door wheel 45 mounted on a hanger rail 44 attached to the upper edge of a refrigerator 41 via an L-shaped bracket 43. A vertical bolt 47 is attached to the lower end of the door hanging moving body 46, and an upper metal fitting 51 shaped as seen from the front is attached to the male threaded portion 48 at the bottom of the vertical bolt 47 by a pair of upper and lower nuts 49, 50. On the other hand, door 42
A lower metal fitting 52 shaped as seen from the front is fixed to the upper edge, and hanging walls 51a, 51 at both ends of the upper metal fitting 51 are fixed.
a is swingably connected to vertical walls 52a, 52a at both ends of the lower metal fitting 52 by bolts 53 and nuts 54 serving as pivots. However, such conventional door hanging tools have the following problems.

() External threaded part 4 of vertical bolt 47 of door hanger
8, especially the lower nut 5
If 0 became loose, there was a risk that the door 42 would fall.

() Also, the height of the door 42 is determined by a pair of upper and lower nuts 49, 5 relative to the male threaded portion 48 of the vertical bolt 47.
Adjustment is made by adjusting the screws at 0, but when turning the lower nut 50, the weight of the door 42 is applied, making it very difficult to turn the nut 50.

() The lower end of the vertical bolt 47 is the horizontal bolt 53
The height adjustment amount of the vertical bolt 47 could not be made large until the height of the door 42 was reached.

() When installing and removing the door 42, it is necessary to move the door 42 to the end of the hanger rail 44 and remove the door roller 45 from the hanger rail 44, and such work is extremely troublesome. Moreover, if there are shields on both the left and right sides of the refrigerator 41, it is impossible to remove the door 42 in this way, and the door hanger itself must be removed from the door 42, making replacement especially difficult if the door is heavy. It was hot.

() Not only does the door hanging tool have a large number of parts, making it difficult to manufacture easily and inexpensively, but it also has an unsightly appearance, requiring a cover to cover the door hanging tool, resulting in high costs.

Purpose of the invention The purpose of this invention is to solve the above-mentioned problems, and to make the work of attaching and removing the door to the hanger rail very easy and hassle-free, and there is no danger of the door falling. It is easy to adjust the height of the door, the amount of height adjustment is large, the number of parts is small, manufacturing is easy and inexpensive, and the appearance is clean and does not require the installation of a protective cover. Don't try to provide a very convenient door hanger.

Structure of the invention In order to achieve the above object, this invention is equipped with a door roller that can be placed on a hanger rail, and has a leg part with a male screw part for height adjustment hanging down at the lower end. an intermediate connecting member having a female threaded portion screwed onto the male threaded portion and horizontal engaging portions on both left and right sides of the female threaded portion; The gist is a door hanger consisting of a hook with a matching hook-shaped engagement part.

Embodiment Next, an embodiment of this invention will be described based on the drawings.

In this specification, front, back, right and left are based on Figure 2, where the front refers to the front side of the sheet of paper in Figure 2, the rear refers to the back side, the left refers to the left side of the same figure, and the right refers to the right side of the same figure. shall be taken as a thing.

1 to 3, the door hanger according to this invention is equipped with a door wheel 12 that is placed on a hanger rail 4 that is attached to the upper edge of the refrigerator door via an L-shaped bracket 3, and a raised door at the lower end. A moving body 11 for hanging a door, in which a leg portion 13 with a male screw portion 14 for height adjustment is provided in a hanging manner, and a male screw portion 1
The intermediate connecting member 21 has a female threaded portion 22 that is screwed together with the door 2 and horizontal engaging portions 23 and 24 on both the left and right sides thereof, and the intermediate connecting member 21 is attached to the upper edge of the door 2 and has a horizontally engaging portion at the upper end. Hook 3 with hook-shaped engaging parts 32, 32 that engage with parts 23, 24
1 and more.

The door suspension movable body 11 has a cylindrical shape with a bottom, and a pivot shaft 15 of a pair of front and rear door wheels 12, 12 is attached to the door suspension movable body 11.
is attached in a penetrating manner, and both ends are caulked.

Further, the intermediate connecting member 21 has horizontal engaging portions 23 and 24.
It is made up of a round rod-shaped member 25 that constitutes a cylindrical member 25, and a cylindrical member 26 that is fitted over the center of the rod-shaped member 25.
A female screw portion 22 is provided in a penetrating manner at the center of the cylindrical member 26 and the round bar member 25 . Rollers 27, 27 are rotatably placed on the left and right horizontal engaging parts 23, 24, respectively, and retaining rings for preventing the rollers from coming off are provided in annular grooves 28, 28 provided at the outer ends of both the horizontal engaging parts 23, 24. 29, 29 are fitted.

Further, the hook 31 has a swinging vertical wall portion 34 provided with hook-shaped engaging portions 32 at the upper end, which is attached to the front edge of a horizontal fixed wall portion 33 fixed to the upper edge of the door 2.
It is swingably attached via 5. A leg relief notch 36 is provided in the vertical wall portion 34 between the hook engaging portions 32 and 32, and the vertical wall portion 3
A pair of left and right screws 37, 37 for preventing the horizontal engaging portion from coming off are attached to a portion near the upper end of 4.

Two sets of door hangers according to this invention are attached to the left and right sides of the upper edge of the door 2, and these door hangers are used to hang the door 2 as follows.
Hang it on rail 4.

First, a pair of door wheels 12 at the front and rear of the door hanging movable body 1
Place it on hanger rail 4. Next, the female threaded portion 22 of the intermediate connecting member 21, on which the rollers 27, 27 and retaining rings 29, 29 have been set in advance, is attached to the movable body 11.
The external threaded part 14 of the leg part 13 of the door 2 is screwed together, and the amount of screwing is adjusted according to the height at which the door 2 is to be installed. On the other hand, a hook 31 is attached to the upper edge of the door 2. And finally, lift this door 2,
