Description

[Detailed Description of the Invention] The present invention relates to a bearing for the door of an audio rack, furniture, or other box body, and the object thereof is to enable the door to be installed easily and accurately.

There is a bearing shown in Fig. 7 that supports a support shaft provided at one end of the door that protrudes up and down, but these are generally embedded in the upper and lower walls of the box body facing each other, and the bearings shown in Figs. The support shaft of the shaft fitting shown in is inserted.

Therefore, it is necessary to match the axes of the shaft holes of the pair of upper and lower bearings, but it is quite difficult to make them match, and there is a drawback that it requires a lot of effort to make them match.

If the axes of the upper and lower pair of bearings do not match in the direction of the frontage of the box, the door will be tilted and it will be easy to see, resulting in an extremely unsightly appearance. This can also cause problems in which it becomes difficult to open and close the door.

This proposal aims to solve the above problems.

To explain this with reference to the embodiment shown in the drawings, reference numeral 1 denotes a bearing body, which is cylindrical and can be fixed in a hole provided in a box body.

In the embodiment, the bearing body 1 is fixed to a box etc. by providing a saw blade-shaped protrusion on the outer circumferential surface of the main body 1 and inserting it into the circumferential surface of a hole provided in the box etc. However, it is also possible to use screws or nails.

Reference numeral 2 denotes a bearing, which has a shaft hole 3 with a bottom or a penetrating shaft, and is provided in the bearing body 1 with the axis of the shaft hole 3 parallel to the axis of the bearing body 1.

The bearing 2 is provided with an engagement mechanism between the bearing 2 and the bearing body 1 in the direction of the insertion side end A of the shaft into the shaft hole 3 so as not to be detached from the bearing body 1. 1, it is slidable in a direction perpendicular to its axis.

Therefore, the hole in the bearing body 1 has a rectangular cross section.
Make it long into an oval shape.

In the embodiment, as the engagement mechanism provided between the bearing 2 and the bearing body 1, retaining walls 4 are provided on the inner surface of the bearing body 1, located at both ends in a direction perpendicular to the sliding direction of the bearing 2, and a stepped portion 5 on the outer surface of the bearing 2 that overlaps with the lower side of the engagement wall 4.
are provided and are engaged with each other.

However, this configuration is not limited to this, and any configuration may be used, such as providing protrusions and grooves that engage with each other on the bearing body 1 and the bearing 2 in a direction parallel to the sliding direction of the bearing 2, as shown in FIG. can be adopted.

Reference numeral 6 denotes a sloped surface provided on the outer surface of the bearing 2 in a direction perpendicular to the sliding direction of the bearing 2, and is provided on the opposite end of the shaft to the bearing 2 from the insertion side.

Reference numeral 7 denotes a spring interposed between the bearing body 1 and the bearing 2 at a position opposite to the slope portion 6, and urges the bearing 2 in the direction of the slope portion 6.

The spring 7 may be provided at a plurality of locations, or may be a tension spring, in which case it is provided on the slope portion 6 side.

Reference numeral 8 denotes a support wall provided on the inner periphery of the bearing body 1 facing the sloped portion of the bearing 2 so as to protrude toward the bearing 2 at the insertion side end of the shaft, and a machine screw 10 is inserted into the hole provided in the support wall. ing.

Reference numeral 11 denotes a movable plate interposed between the support wall 8 and the inner surface of the bearing body 1. A small screw 10 is inserted into a screw hole 9 provided in the movable plate 11, and one end of the movable plate 11 is joined to the slope portion 6. screw 1
The movable plate 11 can be moved along the rotation by zero rotation, and the movement of the movable plate 11 causes the bearing 2 to slide in its radial direction.

12 is a support shaft that is installed above and below the door and inserted into the bearing 2;
Reference numeral 3 denotes a mounting body having a concave cross section for attaching the support shaft 12 to the door, and the support shaft 12 is fixedly protruding from this.

Reference numeral 14 denotes a fixing screw that penetrates and is attached to one of the opposing walls of the mounting body 13. Reference numeral 15 denotes a shaft bearing for pivotally supporting the support shaft 12, which is shaped like a pipe and can be fixed to a box or the like.

16 is a box, and 17 is a recess provided in the box 16, into which the main body 1 is fitted.

18 is a door. In the above configuration, the bearing body 1 can also be shaped like a cylinder with a bottom.

The mounting body 12 does not need to be limited to a concave cross-section, but can be made to have a cross-section such as a curved shape so that the support shaft 11 can be fixed to the door.

When this bearing is used to attach a door to a box, etc., it is embedded in the top and bottom walls of the box, and the bearing main body 1 is fixed to one side of the box, and the bearing body 15 is fixed to the other side facing each other.

In this case, instead of the bearing body 15, it is also possible to use only a pair of bearing bodies 1.

In the bearing body of the example shown in FIGS. 2 and 3, the lower surfaces of the bearing body 1 and the bearing 2 are lightly joined to the bottom surface of the recess 17 provided in the box body 16, and the bearing 2 is connected between the engagement wall 4 and the bottom surface of the recess 16. It is suitable that the bearing 2 be in a clamped state and that the bearing 2 cannot be tilted.

A bottom cover to be joined to the bearing 2 may be fixed to the bottom of the bearing body 1.

In the bearing body 1 shown in FIG. 4, the above consideration is unnecessary.

The slope of the door 18 is unsightly if it is tilted in the left-right direction when the door is closed, and it tends to interfere with opening and closing. It is suitable that it be parallel to the rim of the mouth, but this is optional.

To attach the door 18 to the bearing body 1 and the bearing body 5 attached to the box body 16 as described above, insert the support shaft 12 into the bearing 2 and the bearing body 5, and then insert the door 18 into the mounting body 13. Fix it.

Then, if the sliding direction of the bearing body 1 and the bearing 2 is parallel to the line of sight of the box body 16, and the door 18 is tilted in the left-right direction or other direction when it is closed, turn the machine screw 10. Then, the moving plate 11 is moved upward or downward according to the direction of rotation.

The end of the moving plate 11 is joined to the inclined surface 5 of the bearing 2, so when the moving plate 11 is raised, for example, it presses the spring 6 and moves the bearing 2 to the left in FIG. ,
Conversely, if the movable plate 11 is lowered, the movable plate 1
1 releases the bearing 2, and the force of the spring 6 causes the bearing 2 to move to the right in FIG.

Therefore, by rotating the machine screw 10 according to the amount and direction of inclination of the door 18, it is possible to correct the misalignment of the axes of the bearing body 15 and the bearing 2, and to make them coincide with each other, so that the door 18 can be straightened. It can be installed neatly and can be opened and closed smoothly.

As described above, in the bearing of the present invention, since the bearing 2 can be slid in the radial direction, it is possible to adjust the shaft holes of the pair of shaft supports without changing the mounting position of the bearing body 1 after installation. can be easily corrected, the bearing installation work can be made easier, and the door can be installed correctly.
