Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sliding door hanger that can easily and quickly adjust the upright position of a relatively large and heavy hanging type sliding door.

[Conventional technology and its problems]

Various types of hanging tools have been developed for suspending hanging type sliding doors from the upper rail, but most of these hanging tools have a threaded rod with a roller that rolls on the upper rail. The distance between the top surface of the sliding door and the top rail is adjusted by rotating a roller adjustment nut (such as a washer-shaped nut) provided between the top surface of the sliding door and the top rail, and the vertical position of the sliding door is thereby adjusted. be.

A narrow distance between the top surface of the sliding door and the upper rail is preferable for appearance and other reasons, but in order to adjust the rotation of the roller adjustment nut within this distance, a distance of at least about 1 cm is required. However,
When the length is approximately 1 cm, it becomes difficult to insert a tool for adjusting the rotation of the roller adjustment nut, making it difficult to adjust the vertical position of the sliding door, and there is a problem in that it is extremely difficult to vertically position the sliding door.

[Means for solving problems]

As a result of intensive research to solve the above-mentioned problems, the inventor developed the present invention by incorporating a vertical hole penetrating upward into the casing and a horizontal circular hole communicating with the vertical hole from the side of the casing. A suspension rod with a sliding slope is loosely inserted into the vertical hole, a washer with an internal screw is fixed in the middle of the horizontal circular hole, the threaded part of the screw rod is screwed into the internal screw, and the rod is moved within the horizontal circular hole. By using a sliding door hanging tool that is flexible and allows the conical tip of the threaded portion to come into contact with the upper surface of the sliding slope of the hanging rod, it is possible to mount a relatively large and heavy hanging type sliding door. can be adjusted easily and quickly, and the above problems have been solved.

Specifically, the F-shaped notch 6 consists of a sliding slope 6a, a continuous surface 6b, and a horizontal surface 6c, and the sliding slope 6a is inward from the lower end of the hanging rod B from one side in the width direction. It is formed in an upwardly sloping shape toward the direction (see Fig. 2). A continuous surface 6b is formed outwardly and upwardly from the upper end of the sliding slope 6a, and a horizontal surface 6c is formed outwardly from the upper end of the continuous surface 6b. Here, the continuous surface 6b may be formed in an inclined shape, a substantially vertical shape, or an arc shape. The hanging rod B is connected to the vertical hole 1 of the housing A.
It is loosely inserted into. At this time, as shown in FIGS. 1 and 2, the F-shaped notch 6 of the hanging rod B

(hang rollers 10 are often attached in advance) and attached to the upper rail 11. Next, the housing A of the sliding door hanger is inserted into the fixing groove 12a of the sliding door 12 and fixed, completing the installation.

Next, in order to adjust the horizontality of the sliding door 12 or the vertical frame of the opening in which the sliding door 12 fits,
By appropriately rotating the non-circular screw head 7c of the screw rod 7 in the horizontal circular hole 2 of the housing A or the rotary tube portion 9, the suspension rod B
is moved in the vertical direction to adjust the inclination of the sides of the sliding door 12 in the width direction, that is, to adjust the standing position.

Furthermore, the order of installing the sliding door 12 is not limited, and for example, it is possible to attach a sliding door hanger to which the hanging roller 10 is attached to the sliding door 12 and attach it to the upper rail 10.

[Effect of idea]

In the present invention, a vertical hole 1 penetrating upward through the casing A and a horizontal circular hole 2 communicating with the vertical hole 1 from the side of the casing A are formed, and a suspension rod B having a sliding slope 6a is provided. Loosely insert the washer 8 into the vertical hole 1, fix the washer 8 with an internal screw in the middle of the horizontal circular hole 2, and tighten the screw part 7 of the screw rod 7.
A is screwed into the inner threaded part 8a to be movable in the horizontal circular hole 2, and the conical tip 7b of the threaded part 7a can come into contact with the upper surface side of the sliding slope 6a of the hanging rod B. Firstly, the hanging type sliding door 12 can be adjusted easily and quickly, secondly, it can be easily installed, and thirdly, the structure is simple and inexpensive. be effective.

To explain these effects in detail, a sliding slope 6a is formed on the hanging rod B, and the conical tip 7b of the screw portion 7a that moves horizontally from above this sliding slope 6a is brought into contact. By rotating the threaded rod 7, the threaded portion 7a moves laterally within the horizontal circular hole 2, and when the lower edge of the conical tip 7b comes into contact with the upper surface side of the sliding slope 6a, the threaded portion 7a moves laterally within the horizontal circular hole 2. The horizontal force F _h of the threaded portion 7 a of the rod 7 is converted into a force F _v that pushes down the suspension rod B, and the suspension rod B can be moved vertically.

In this way, vertical movement can be caused in the hanging rod B by the screw rod 7 provided horizontally, so when the sliding door hanging tool of the present invention is attached above both sides of the sliding door 12 in the width direction, The verticality of the left and right sides of the sliding door 12 can be freely adjusted. In other words, the vertical position of the sliding door 12 can be suitably adjusted. In particular, adjusting the standing position is an important point, and if this cannot be adjusted or is difficult, generally in the industry,
It is even said that it is impossible to provide the hanging door 12 on the upper rail 11.

That is, conventionally, the hanging tool is attached to the top surface of the sliding door 12, and the adjustment portion of the hanging tool also exists in the narrow space between the upper rail 11 and the top surface of the sliding door 12. Therefore, it was necessary to insert a tool such as a spanner between the sliding door 12 and the upper rail 11 to adjust the upright position, and this work was extremely troublesome because the distance between the sliding door 12 and the upper rail 11 was narrow. However, in this invention,
The adjustment part of the sliding door hanger does not exist between the upper rail 11 and the sliding door 12, and it can be adjusted only from the side, making it extremely easy to adjust the standing position.
2 and the upper rail 11 has the advantage that work can be performed without being affected at all.
Therefore, in the present invention, the distance between the top surface of the sliding door 12 and the upper rail 11 can be almost eliminated (approximately 1 mm to 1 mm).
(approximately 2 mm), which not only improves the appearance, but also makes it extremely easy to stand and adjust only the side of the sliding door 12.

Furthermore, in the present invention, the contact portion between the conical tip 7b of the screw rod 7 and the sliding inclined surface 6a is a line, but
If the strength of the threaded portion 7a is high, the threaded rod 7 can be moved in the horizontal direction by rotating the threaded portion 7a with a relatively small force, and thereby the hanging rod B can be moved up and down. This can reduce the labor of workers during work, and can also improve work efficiency.

As described above, the present invention has a structure in which only the screw rod 7, internal screw washer 8, and hanging rod B, which are screws, bolts, etc., are built into the housing A, and has the advantage that the structure is simple and can be provided at low cost. There is.
