Description

[Detailed description of the invention] This invention relates to a runner that hangs a sliding door and moves inside the hanger rail to open and close the door.The conventional runner is as shown in Figures 9 and 10. To, runner 5
1, in which a plurality of steel balls 52 are each mounted in an arched manner on the bottom surface. If such a runner only runs back and forth on a straight hanger rail, the wear of the steel balls will be uniform, so there will be many problems, but if the hanger rail is curved and falls or crosses at right angles, When the door is constantly moved from one place to another, the steel balls are partially worn out, making it difficult to open and close the sliding door smoothly, which is extremely inconvenient.

In view of these shortcomings, this idea was developed so that no matter what shape the hanger rail has, the steel balls have less wear and are always kept evenly, so that the sliding door can be opened and closed smoothly. This is what I did.

An embodiment of this invention will be explained below using the figures. 1 is a hanger rail, 2 is a main body of a runner,
3 is an upper cover of the runner, 4 is a groove, 5 is a vertical hole, and 6 is a steel ball, and the groove 4 has an arc shape in which a circle is divided into multiple equal parts at the same position on both the top and bottom surfaces of the main body 2.
has a width that allows the steel balls 6 to freely roll and move, for example, and in the embodiment, one steel ball 6 is placed at each end of the groove 4 on each of the corresponding top and bottom surfaces. A vertical hole 5 is provided to allow free passage.

7 is a bottom plate, 8 is an arc-shaped hole, and the bottom plate 7 has an arc-shaped hole corresponding to the arc-shaped groove 4 on the bottom of the main body 2, and the steel ball 6 is inserted into the groove 4 on the bottom of the main body 2. When the bottom plate 7 is attached to the main body 2, the steel balls 6
A part of the lower part of the steel ball 6 comes out from the arcuate hole 8, and the depth of the groove 4 on the bottom of the main body 2 is such that a part of the lower part of the steel ball 6 comes out from the arcuate hole 8 as described above. As shown in Figure 7, it has a depth that allows it to be constantly exposed.

Moreover, when the bottom plate 7 shown in FIG. 6 is used instead of the bottom plate 7 shown in FIG. It has a size and shape that allows it to be exposed.

9 is a bearing, 10 is a bolt for hanging a sliding door, 11 is a nut to be combined with the bolt 10, and a few steel balls 6 are inserted into all of the grooves 4 and vertical holes 5 on the top and bottom surfaces of the main body 2. Fit it with enough room, put the top cover 3 on it, place the bottom plate 7 on it, and then tighten the bolts 10 and nuts 1.
Assemble the runner by fixing the main body 2 in step 1.

Next, in the main body 2 according to the embodiment shown in FIG. A pin 12 is inserted into the main body 2, and one steel ball 6 can freely pass through the right and left vertical holes 5' of the pin 12, respectively. the same as,
Fit the steel ball 6 into the groove 4 and vertical hole 5' on the top and bottom surfaces with some allowance, and place the top cover 3 and bottom plate 7 on.
Secure with bolts 10 and nuts 11 and assemble.

Since the runner according to this invention has the above-mentioned structure, this runner is fixed to the upper part of the sliding door with bolts 10, fitted to the hanger rail 1, and the sliding door is opened and closed by hanging it. In this case, if the runner moves in the direction of arrow X in Figure 7 when the hanger rail 1 curves or crosses in a cross direction and changes direction, the runner will come into contact with the hanger rail 1. The lower steel balls 6 rotate as the runner moves, moving in the opposite direction to the direction of arrow X, and the upper left steel ball 6 of the groove 4 fits into the gap created on the left side. The lower steel ball 6 is pushed to the right, and the rightmost steel ball 6 is pushed up in the direction of arrow Y in the diagram. The balls 6 sequentially move to the right and are pushed up, causing the steel balls 6 to circulate in the grooves 4 and smooth the movement of the runner.

Note that when the moving direction of the runner and the direction of the arcuate groove 4 are almost the same, the steel balls 6 circulate and roll as described above, and when the direction of the groove 4 is not the same, the steel ball 6 rolls downward in the groove 4. Since the steel balls 6 rotate at each position, the steel balls 6 roll smoothly no matter where the contact area between the runner and the hanger rail 1 is, and unlike conventional runners, only a part of the steel balls will wear out. Since there are no holes, it is extremely effective in ensuring that the sliding door always opens and closes easily and smoothly.

Claims (1)

[Claim for Utility Model Registration] Arc-shaped grooves 4, which are divided into multiple equal parts of a circle, are dug in the same position on both the top and bottom surfaces of the main body 2 of the sliding door runner. It has a width and depth that allows it to roll and move freely, and a vertical hole 5 through which a steel ball 6 can freely pass is bored at each end of each groove 4 on both sides of the top and bottom surfaces. Fit the steel balls 6 into all of the holes 5 and the corresponding grooves 4 on the top and bottom surfaces with some allowance, and then complete the main body 2.
A top cover 3 is attached to the upper surface, and a bottom plate 7 having an arcuate hole 8 corresponding to the groove 4 is attached to the bottom surface. Runner for sliding door fixed and assembled. The two adjacent vertical holes 5 of the main body 2 in item 1 above are collectively inserted, and the pins 12 are inserted into several places in the center of one oblong vertical hole 5.
The steel balls 6 are fitted into the respective grooves 4 on the top and bottom surfaces of the main body 2 with a slight margin so that the steel balls 6 can freely pass through both sides of the pin 12.
