Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auto-hinge for mounting a joint concealing member that closes a gap in a fitting portion of a door such as furniture that uses a double-opening type.

[0002]

[Prior art]

 In recent years, a joint concealing member that closes the gap between the door summing portions has been rotatably attached to the free end of one door by an automatic hinge so that it can be opened and closed from either the left or right door.

That is, as shown in FIG. 4, the base 11 of the auto hinge 1 is attached to the inside of the free end of one door 21, and the main body 12 of the auto hinge is freely rotatable on the base 11 by a pivot pin. The joint hiding member 3 is attached to the auto-hinge main body 12 so as to be biased in the opening direction by a coil spring (not shown) attached to the pivot pin.

When the doors 21 and 22 are closed, the joint concealing member 3 abuts on the door catch 5 attached to the opening end of the furniture main body 4 and is substantially parallel to the doors 21 and 22 against the biasing force of the coil spring. The joint 6 is designed to close the gap 6 between the doors 21 and 22 and the joint hiding member 3 is opened by the biasing force of the coil spring when the door 21 with the joint hiding member 3 is opened. The door 21 can be opened by rotating in the opening direction without hitting the other door 22.

[0005]

[Problems to be solved by the device]

However, in the conventional auto hinge 1 , as shown in FIG. 5, the auto hinge main body 12 is pivotally attached by the pivot pin 8 whose tip is press-fitted to the other bearing portion 72 formed on the base 11. However, there is a problem that the assembly is difficult.

That is, at the time of assembly, a pair of pivot shafts formed on the auto hinge main body 12 are positioned between the bearing portions 71 and 72, and a coil spring is interposed between the pair of pivot shafts to provide one bearing portion 71. It is necessary to insert the pivot pin 8 from the side and press the tip of the pivot pin 8 into the other bearing portion 72 through one pivot shaft, the coil vane, and the other pivot shaft.

Therefore, the pin hole of the pivot shaft and the pivot pin penetration portion of the coil spring must be aligned with the pin holes of the bearing portions 71 and 72 by using a jig or the like, but the coil spring has an elastic force. Therefore, there is a problem that the work is difficult and requires skill.

[0008]

[Means for Solving the Problems]

 Therefore, the present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an auto hinge that can be easily assembled, and the auto hinge main body is formed on a base attached to a free end of a door. One of the paired bearings is provided with a fitting hole into which the pivot shaft formed in the auto hinge body is rotatably inserted, and the pivot shaft is rotatably fitted inside the other bearing. A fitting groove is formed, and a pivot pin insertion hole whose hole core coincides with the fitting hole is formed in the bearing portion, and the fitting hole is formed in one of the pair of pivot shafts of the auto hinge body. It is characterized in that a fitting insertion part for fitting and fitting is extended and a fitting part for fitting in the fitting groove is formed on the other pivot shaft.

【Example】

Hereinafter, the present invention will be described according to illustrated embodiments. 50 is a automatic hinge for attaching the joint hidden member closing the gap between the mating portion callings casement doors, is configured to auto hinge body 51 and the automatic hinge body 51 from the base 52 to be attached to the rotating available-to door There is.

[0010] pivot shaft 53, 54 forming a pair to the base end sides of the automatic hinge body 51 is formed, hand extended in fitting portion 531 is integrally projecting from automatic hinge body 51 in the pivot shaft 53 of the The other pivot shaft 54 is integrally provided with a fitting portion 541 projecting from the auto hinge main body 51 and shorter than the fitting insertion portion 531. Reference numeral 532 is a pin hole formed in the pivot shaft 53, and 542 is a pin hole formed in the pivot shaft 54.

A pair of bearings 55, 56 for pivotally mounting the auto hinge main body 51 is formed on the surface of the base 52 , and one of the bearings 55 has a fitting insertion portion 531 formed on the auto hinge main body 51. A fitting hole 551 for fitting and fitting is formed in the other bearing portion 56, and a fitting groove 561 for fitting the fitting portion 541 formed in the auto hinge main body 51 is formed in the other bearing portion 56.

The fitting groove 561 is a U-shaped groove having a semicircular bottom portion, and the center of the semicircular arc is made to coincide with the core of the fitting hole 551.

Further, the bearing portion 56 is provided with a pivot pin insertion hole 57 whose hole core coincides with that of the fitting hole 551, and a slot which reaches the pivot pin insertion hole 57 from the outside of the bearing portion 56. The hood 58 is formed. The diameter of the pivot pin insertion hole 57 is formed to be slightly smaller than the diameter of the pivot pin 59. In the figure, reference numeral 60 is a coil spring.

Next, a method of assembling the auto hinge 50 will be described. First, the fitting insertion portion 531 of the auto hinge main body 51 is fitted into the fitting hole 551 of the base 52, and the fitting portion 541 is fitted into the fitting groove 561. At this time, since the hole core of the fitting hole 551, the semicircular arc-shaped center of the bottom of the fitting groove 561 and the hole core of the pivot support pin insertion hole 57 are aligned with each other, the pivot support pin insertion hole is formed. The hole core of 57 and the pin holes 532 and 542 of the pivot shafts 53 and 54 coincide with each other.

Next, a jig such as a driver is inserted into the slit 58, and the pivot pin insertion hole 57 is widened together with the slit 58. Then, the pivot pin 59 is inserted through the pivot pin insertion hole 57, and when the tip thereof comes to the middle of the pivot shafts 53, 54, the coil spring 60 is fitted to the pivot pin 59, and the tip thereof is further. After inserting the pin hole 532 of the pivot shaft 53, the jig is removed.

[0016]

[Effect of device]

 As described above, according to the present invention, the pivot shaft formed on the auto hinge body is rotatably fitted and inserted into one of the pair of bearings formed on the base that mounts the auto hinge body on the free end of the door. A fitting hole is bored, a fitting groove for rotatably fitting the pivot shaft is formed inside the other bearing portion, and a pivot pin is inserted into the bearing portion such that the fitting hole and the hole core are aligned. A hole is formed, and a fitting insertion portion for fitting and fitting into the fitting hole is extended to one of a pair of pivot shafts of the auto hinge body, and a fitting portion for fitting to the fitting groove is fitted to the other pivot shaft. When the auto hinge body is attached to the base by forming a joint, the pin hole of the pivot shaft and the hole center of the pivot pin insertion hole are aligned so that the pivot pin is extremely easy. Can be inserted into.

Further, according to the present invention, the hole diameter of the pivot pin insertion hole is formed slightly smaller than the diameter of the pivot pin, and the slit reaching from the outside of the bearing portion to the pivot pin insertion hole is formed. When inserting the pivot pin, it can be inserted smoothly by expanding the pivot pin insertion hole with a jig such as a screwdriver, and after insertion, by removing the jig, the diameter of the pivot pin insertion hole becomes As it returns and tightens the pivot pin, it is securely fixed and will not come off. Therefore, it is not necessary to press-fit or crimp the pivot pin as in the conventional case.
