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, which includes a vertical hole penetrating upward into the casing, and a horizontal non-circular hole communicating with the vertical hole from the side of the casing. and an adjusting screw part, which is made expandable and retractable by inserting a suspension rod having a sliding slope surface loosely into the vertical hole and screwing the screw rod into a pressing non-circular protrusion having a pressing slope surface at the tip. Inside the horizontal non-circular hole,
By making the sliding door hanging tool so that the pressing non-circular protrusion can slide into the horizontal non-circular hole without rotating, and the lower surface of the pressing slope can come into contact with the upper surface of the sliding slope, the This invention solves the above-mentioned problems by easily and quickly adjusting the upright position of a large and heavy hanging type sliding door.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 9.

Reference numeral A denotes a housing, which is made of synthetic resin, metal, or the like, and has a flat plate shape as shown in FIG. A flat vertical hole 1 is formed inside the casing A, and a polygonal (quadrilateral etc.) cross section,
Horizontal non-circular holes 2, such as elliptical ones, are formed and are perpendicular to each other inside the housing A (see FIG. 2).

A stepped portion 2a is formed at the outer end of the horizontal non-circular hole 2 (outer surface of the housing A), and the portion outward from the stepped portion 2a of the horizontal non-circular hole 2 is a small circular diameter portion. Further, at the lower end of the casing A, a substantially cylindrical enlarged part 3 is horizontally formed which bulges further outward than both sides of the upper part, and a fixing through hole 4 is formed in the enlarged part 3. (See Figures 1, 2, and 9).

Reference numeral B denotes a hanging rod, which is shaped like a strip and has an arcuate upper part, and a bearing hole 5 is bored therein. The width direction of the lower part of the suspension rod B (left and right direction in Figure 2)
A F-shaped notch 6 is formed approximately in the center from one side. 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 upward 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 loosely inserted into the vertical hole 1 of the housing A. At this time, as shown in FIGS. 1 and 2, the F-shaped notch 6 of the hanging rod B is arranged so as to face the inner end of the horizontal non-circular hole 2 (the part perpendicular to the vertical hole 1). .

Reference numeral C denotes an adjustment screw portion, which is composed of a screw rod 7 and a pressing non-circular protrusion 8. The screw rod 7
The flange portion 7b is formed from one end of the threaded portion 7a,
A screw head 7c is formed on the flange 7b. A locking groove 7d for a Phillips or flat head screwdriver is formed on the upper surface of the screw head 7c. The pressing non-circular projection piece 8 has an internal threaded portion 8a formed therein, into which the threaded portion 7a of the threaded rod 7 is screwed (see FIG. 4). The outer shape of the pressing non-circular protruding piece 8 is such that the cross section perpendicular to the longitudinal direction thereof is a polygon (quadrilateral, etc.),
It is formed into a non-circular shape such as an ellipse, and specifically, as shown in FIG. 4, it may be square-shaped, or although not shown, a part of the circle may have a straight portion formed therein. The pressing non-circular projection piece 8 is designed to slide within the horizontal non-circular hole 2 without idling, and therefore, the horizontal non-circular hole 2 also has the same cross-sectional shape as the pressing non-circular projection piece 8. (See Figure 3).

The lower side of the tip of the non-circular pressing piece 8 (in the vertical direction in FIG. 2) is formed with an outwardly upward pressing slope 8b, and specifically, as shown in FIG. It has the same slope as the sliding slope 6a. The upper end of the pressing inclined surface 8b corresponds to the continuous surface 6b of the F-shaped notch 6, and is formed in an inclined shape (see FIG. 4) or a vertical shape (see FIG. 5).

The adjusting screw portion C is installed in the horizontal non-circular hole 2 of the housing A. Specifically, the screw head 7c of the screw rod 7 is exposed from the outer end of the horizontal non-circular hole 2 (at the outer surface of the housing A), and the flange portion 7b abuts against the step portion 2a.

Further, the pressing non-circular protruding piece 8 can freely protrude into the vertical hole 1 from the inner end of the horizontal non-circular hole 2 (a location perpendicular to the vertical hole 1) (see FIG. 2). and,
The pressing inclined surface 8b of the pressing non-circular projection piece 8 and the sliding inclined surface 6a of the hanging rod B are in contact with each other inside the housing A, and the screw rod 7 is exposed from the outside of the housing A to the horizontal non-circular hole 2.
By rotating the screw head 7c with a screwdriver or the like, the pressing non-circular projection piece 8 moves in the horizontal direction without rotating, and the pressing slope 8b slides on the sliding slope 6a of the hanging rod B. Thus, the suspension rod B is configured to move vertically with respect to the vertical hole 1.

Reference numeral 9 in the figure is a hang roller, in which a roller 9b is pivotally supported on a cart 9a. The hanging roller 9 is attached to the bearing hole 5 of the hanging rod B by a shaft rod 9c.

10 is an upper rail on which rollers 9b of the hang rollers 9 roll. 11 is a sliding door, and fixing grooves 11a, 11a are formed at both upper ends of the sliding door 11 in the width direction (left-right direction in FIG. 7) (see FIG. 9).

The fixing groove portion 11a is enlarged into a cylindrical shape so that its lower end corresponds to the enlarged portion 3 of the housing A. The sliding door hanging tool inserted into the fixing groove 11a is inserted into the fixing through hole 4 with a fixing tool 1 such as a bolt or screw.
2 to the sliding door 11 (see FIG. 9).

[Effect]

A hang roller 9 is attached to the hanging rod B of the sliding door hanger of the present invention (the hang roller 9 may be attached in advance) and attached to the upper rail 10. Next, the housing A of the sliding door hanger is inserted into the fixing groove 11a of the sliding door 11 and fixed, completing the installation.

Next, in order to adjust the horizontality of the sliding door 11 or the vertical frame of the opening in which the sliding door 11 fits,
The screw head 7c of the screw locking rod 7 exposed through the horizontal non-circular hole 2 of the casing A is rotated as appropriate, and the hanging rod B is moved vertically to adjust the inclination of the side part in the width direction of the sliding door 11, that is, to adjust the vertical direction of the sliding door 11. Make the following adjustments.

Further, the installation order of the sliding door 11 is not limited, and for example, it is also possible to attach a sliding door hanger to which the hanging rollers 9 are attached to the sliding door 11 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 non-circular hole 2 communicating with the vertical hole 1 from the side of the casing A are formed, and a suspension rod having a sliding slope 6a is formed. Loosely insert B into the vertical hole 1, press the inclined surface 8b
A screw rod 7 is screwed into a pressing non-circular protrusion 8 having an extensible adjustment screw part C inside the horizontal non-circular hole 2, and the pressing non-circular protrusion 8 is inserted into the horizontal non-circular hole. 2, the lower surface side of the pressing inclined surface 8b can come into contact with the upper surface side of the sliding inclined surface 6a, first of all, the sliding door of the hanging type can be slid. 11 can be easily and quickly adjusted, secondly, the vertically position can be adjusted easily, and thirdly, it can be made stronger.

To explain these effects in detail, a sliding slope 6a is formed on the hanging rod B, and a pressing slope 8b of a pressing non-circular protrusion 8 that moves horizontally from above the sliding slope 6a comes into contact with the hanging rod B. By rotating the screw rod 7 of the adjustment screw part C, the pressing non-circular projection piece 8 can be slid into the horizontal non-circular hole 2 without rotating. When the protruding piece 8 moves laterally within the horizontal non-circular hole 2 and the lower surface side of the pressing inclined surface 8b of the pressing non-circular protruding piece 8 comes into contact with the upper surface side of the sliding inclined surface 6a, the pressing non-circular protruding piece 8 becomes horizontal. Power
F _h is converted into a force F _v that pushes down the suspension rod B, and the suspension rod B can be moved in the vertical direction.

In this way, vertical movement can be caused in the hanging rod B by the adjustment screw part C provided horizontally, so when the sliding door hanging tool of the present invention is attached above both sides of the sliding door 11 in the width direction. The verticality of the left and right sides of the sliding door 11 can be freely adjusted. In other words, the vertical position of the sliding door 11 can be suitably adjusted. In particular, adjustment of the vertical position is an important point, and if this cannot be adjusted or is difficult, it is generally said in the industry that it is impossible to provide the sliding door 11 on the upper rail 10.

That is, conventionally, a hanging tool is attached to the top surface of the sliding door 11, and the adjustment portion of the hanging tool also exists between the upper rail 10 and the top surface of the sliding door 11. Therefore, it is necessary to insert a tool such as a spanner between the sliding door 11 and the upper rail 10 to adjust the vertical position, and the adjustment work becomes extremely troublesome because the distance between the sliding door 11 and the upper rail 10 is narrow. However, in the present invention, the adjustment part of the sliding door hanger is connected to the upper rail 10 and the sliding door 1.
There is no gap between the sliding door 1 and the sliding door 1, and it can be adjusted only from the side, making it extremely easy to adjust the standing position.
1 and the upper rail 10 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 11 and the upper rail 10 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 up and adjust only the side of the sliding door 11.

In addition, in the present invention, the adjustment screw portion C replaces the rotation of the screw rod 7 with a horizontal pressing force F _h (see FIG. 6) using a pressing non-circular projection piece 8. Therefore, even if the weight W of the sliding door 11 is extremely large and the contact pressure between the pressing non-circular projection piece 8 and the sliding inclined surface 6a is extremely large, the screw rod 7 can be moved with a relatively small force.
By rotating , the pressing non-circular protruding piece 8 can be moved in the horizontal direction. This can reduce the labor of workers during work, and can also improve work efficiency.

Next, since the pressing non-circular projection piece 8 is formed with the pressing slope surface 8b, the sliding slope 6a of the hanging rod B and the pressing non-circular projection piece 8 come into almost surface contact, and the sliding door 11 Even if the contact resistance between the pressing inclined surface 8b and the sliding inclined surface 6a caused by the weight W is large, it can be sufficiently withstood, and is particularly effective against impact when the sliding door 11 is opened and closed.
