Description

[Detailed Description of the Invention] [Industrial field of application] This invention relates to a hinge in which the mounting position of a door or the like can be adjusted up and down, and more specifically, it is mounted by moving the shaft pin up and down by operating the screw engagement amount. The present invention relates to a detachable blade hinge for adjusting the position.

[Prior Art] In this type of hinge, for example, the actual applicant of the present invention Sho 58-1
Those described in Japanese Patent No. 95763 are known. This is a configuration in which a threaded surface is formed on the inner peripheral surface of the end of the shaft cylinder portion of the blade to screw the screw member and the star is screwed to the screw member. Is operated to adjust the vertical movement of the shaft pin. However, in the case of the above-mentioned configuration, there are many screw forming portions, and it is not always desirable from a manufacturing standpoint because it is not easy to form a screw surface in the shaft cylindrical portion that is usually formed by bending the extended portion of the blade plate. However, it was troublesome to remove the Gisoshi at each adjustment operation.

Therefore, the applicant of the present invention, in Japanese Utility Model Laid-Open No. 62-16671, has a structure in which a tapping-capable collar member is fixed in at least one opening of each shaft cylinder portion, and a screw member is tapped into a hole of the collar member. Suggested things.

[Problems to be solved by the device]

By the way, the tapping structure has the advantages that it is not necessary to form a threaded surface on the shaft cylinder portion and the productivity is good, and that the screw member can be directly operated from the outside. However, even if the collar member has a good tapping property, a certain amount of labor for tapping is inevitable, and the mounting work is not always easy. In addition, since the screw surface becomes soft, deterioration over time due to damage to the screw surface cannot be denied.

Therefore, an object of the present invention is to provide a hinge that can be easily attached and operated and that can maintain the strength of the adjusting screw portion for a long period of time.

[Means for solving the problem]

This invention was devised in order to achieve the above-mentioned object, and its feature is that the shaft pin is detachably fitted into the shaft cylinders of the pair of left and right blades, and at least one of the upper and lower ends of the shaft pin is inserted. A screw member is screwed in the screw hole provided in the shaft direction, and a retaining portion for preventing the screw member from coming off is formed at the axial end of the shaft cylinder portion located on the screw member side. In the configuration, an operation hole for rotating the screw member from the outside is formed.

[Action]

According to this invention, if it is necessary to adjust the vertical mounting position of the door with the pair of left and right blades fixed to the main body and the door, for example, the operation tool is inserted from the operation hole of the lower shaft cylinder portion. Then, the screw member is rotated. Since the screw member is retained by the retaining portion, the vertical movement of the shaft pin is adjusted by the amount of change in the screwing amount of the screw member, thereby adjusting the vertical mounting position of the door.

〔Example〕

 1 to 4 show an embodiment of the present invention.

In the figure, reference numerals 2 and 4 are blade plates attached to the solid body A and a door (not shown), 6 and 8 are shaft cylinder portions of the blade plates 2 and 4, and 10 is a shaft inserted into each shaft cylinder portion 6 and 8. Pins, 12 are protrusions provided near the middle of the shaft pin 10 for preventing rotation, and 14 is a protrusion 12
Is a receiving groove provided in the vane plate 2 in a notched manner or in a seam manner for engaging with. In addition, the blade plate 4 has a countersink
15 pieces are formed and fixed with set screws 17.

A collar portion 16a and a cylindrical portion 16b are provided at the axially outer end 8a of the shaft tube portion 8.
Gishiro 16 consisting of and is inserted and fixed by means such as spot welding. The top 10 of the axis pin 10 by this star 16
a is locked out. In addition, a spherical body 18 is embedded in the upper end 10a of the shaft pin 10 in order to reduce contact friction with the star 16 and improve smoothness when opening and closing the door.

A screw hole 20 is formed in the lower end portion of the shaft pin 10 in the axial direction, and a screw member 22 having an operating head portion 22a that can be rotated by an operating tool such as a screwdriver is screwed into the screw hole 20. ing. Correspondingly, a star 24 having a collar portion 24a and a cylindrical retaining portion 24b is fitted and inserted into the axially outer end 6a of the shaft tubular portion 6. The operation head 22a of the screw member 22 has a retaining portion 24b.
It is locked to the upper end 24c of the to prevent it from coming off. Further, the inner hole of the star 24 serves as an operation hole 26, and an operation tool is inserted from the outside through the operation hole 26 to adjust the screwing amount of the screw member 22. A commercially available set screw can be used for the screw member 22, and the inner diameter of the retaining portion 24b can be determined correspondingly.

The operation head portion 22a of the screw member 22 can be variously selected from those having a groove for a driver or the like, and those having a convex portion or a concave portion for a box wrench or a square wrench.

Next, the operation of the vertical adjustment will be described with reference to FIGS. For example, when it is necessary to shift the mounting position of the door upward, the operation tool is inserted into the operation hole 26, the screw member 22 is rotated, and the screwing amount with respect to the screw hole 20 is changed from d ₁ to d _2. It This positions the door upward by the dimension (d ₁ −d ₂ ).

As described above, the screw member 22 is screwed into the end portion of the shaft pin 10, and the screw member 22 is formed at the outer end of the shaft tube portion 6 in the operation hole 26.
If configured to operate from, the shaft pin 10 as a solid member
In addition to the screw forming on the bottom, the productivity is good because there are few screw forming parts. Further, since the screw member can be simply screwed into the screw portion of the already formed shaft pin and directly adjusted from the outside, the mounting work and the operation are facilitated. Furthermore, deterioration due to damage to the screw surface can be avoided.

The hinge according to this example has a structure for adjusting the inclination of the door with respect to the fixed body A.

As shown in FIGS. 1 and 4, the blade plate 2 is provided with a plurality of countersinks 15 for the set screws 17, and a round hole 32 corresponding to the adjustment screw 30 is provided at a vertical position suitable for tilt adjustment. Has been formed. The adjusting screw 30 is formed with a collar portion 30a that is locked to the back side of the round hole 32, and
A concave or convex operation portion 30b for rotationally operating from the front side of the round hole 32 is formed on the head end surface. Adjustment screw 30
Is attached to the fixed main body A via an embedding member 34, and an embedding hole 36 for the embedding member 34 is formed in the fixed main body A. The embedding member 34 can be formed of, for example, a tappable resin in a shape having an inner hole 34a and a multi-step hook portion 34b on the outer peripheral surface.

By making the outer diameter of the hook portion 34b slightly larger than the diameter of the embedding hole 36, embedding and fixing in the embedding hole 36 can be obtained only by the embedding operation. The adjusting screw 30 is screwed into the inner hole 34a by tapping, and its tip is directly screwed into the fixed body A. Of course, the embedding member 34 and the adjusting screw 30 may be screwed together not by tapping, but by screwing with an ordinary preformed screw. The embedding member 34 maintains the screwing strength of the adjusting screw 30 with respect to the fixed main body A, which is usually a wooden material, and avoids problems such as unadjustability, rattling, and positional deviation due to the screw surface collapse. Also, the set screw 17 may be attached via the embedding member 34.

An example of mounting and tilt adjustment according to the above configuration will be described. First, the embedding member 34 is press-fitted into the embedding hole 36, and the adjusting screw 30 is inserted.
Is screwed by tapping or the like. Next, cover the head of the adjusting screw 30 with the blade plate 2 and temporarily fix it, screw in the fixing screw 17 and stop it in about 8 minutes, adjust the adjusting screw 30 by a predetermined dimension c, and then tighten the fixing screw 17 to fix it. To do.

Next, FIG. 5 shows another embodiment, which is an example in which the male and female forms of the shaft pin 10 and the screw member 22 in the above example are reversed. The same parts as those in the above example are designated by the same reference numerals.

A shaft pin 40 that is located approximately in the middle and has a flange 38 integrally formed therewith.
A male screw portion 42 is formed at one end of the, and a screw member 44 having a female screw portion 44a is screwed into the male screw portion 42. Similar to the above example, the screw member 44 is formed with an operating head portion 44b having a concave or convex operating surface. The lower limit position of the blade plate 4 with respect to the shaft pin 40 is regulated by the flange portion 38. The vertical adjustment is the same as in the above example.

In addition, in this example, splines can be formed on the circumferential surface of the cylindrical portion or cylindrical portion 16b of the star 16. By doing so, there is an advantage that the fixing to the outer end portion of the shaft tube portion 8 becomes strong only by a simple press-fitting operation, and a fixing means such as welding can be omitted.

[Effect of device]

According to this invention, since the threaded surface is formed on the shaft pin as a single component, the manufacturing is easier and the productivity can be improved as compared with the case where the shaft pin is usually formed integrally with the blade plate. it can. Further, since the screw member can be simply screwed into the screw portion of the already formed shaft pin and directly adjusted from the outside, the mounting work and the operation can be facilitated and the deterioration due to the screw surface damage can be avoided.
