Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a hinge used for a door, and provides a novel hinge having a locking mechanism for locking the door in the open position.

"Prior Art" and "Problems to be Solved by the Invention" A conventional hinge has two blades connected via a shaft so that they can be opened and closed, and one of the blades is attached to the edge of the door. The other end is attached to a pillar or the edge of a building entrance, and the hinge supports the door and opens and closes the door.

The conventional hinge structure described above does not allow the door to be fixed in the fixed position, so the door may move or slam due to wind or vibration. Therefore, a method is generally used to fix the opening position of the door at a required opening angle, such as 90 inches, by attaching a door chair, car, or stopper known in the art.

However, if the above-mentioned door chairs, cars, and stoppers are installed, they can cause tripping when passing by, become an obstacle when cleaning, and require the effort to lock the door every time the door is opened. This makes opening and closing the door a hassle.

If such attachments are installed, installation work will be labor-intensive, and the door structure will become complicated.
Further, the above-mentioned door chairs and cars have many disadvantages, such as difficulty in attaching them to gates and the like.

The present invention aims to solve the above-mentioned drawbacks of the prior art, and provides a novel hinge incorporating a locking mechanism for locking the door in the open position.

``Means for Solving the Problems'' The present invention that achieves the above objects has ``a pair of tubular bearings that are vertically combined along a common axis, and that can be opened and closed freely in the pair of tubular bearings. In the hinge provided with a wing portion, the pair of tubular bearing portions are rotatable in conjunction with the tubular bearing portion on one side, and are rotatable relative to the tubular bearing portion on the other side. A common slide shaft that is constantly biased in the direction of is mounted, and furthermore, both ends of the slide shaft are in pressure contact with the edge of the tubular support on the other side, and the ends of the slide shaft are in pressure contact with the edges of the tubular support on the other side. A locking pin with both ends accommodated in the storage notch of the tubular support is horizontally fixed, and a locking groove for receiving the end of the locking pin is formed at the edge of the other side of the tubular support. The present invention is characterized in that a locking structure is provided in which the locking pin and the locking groove engage with each other at a required opening position of the door to lock the door in the open position.

``Operation'' The hinge of the present invention, which has the above-mentioned means as its main part, has a sliding shaft that is biased and rotates in conjunction with the tubular support on one side at any opening position of the door. The door slides toward the tubular support, and the locking pin of the slide shaft engages with the locking groove of the tubular support on the other side, so that the door can be automatically locked in the open position.

"Example" A detailed explanation will be given below based on an example. Referring to FIG. 1.2 showing one embodiment thereof, the hinge of the present invention has a pair of tubular bearing parts 2A2B combined on the upper side and the lower side along a common axis 2'. Each of 2A2B is provided with one blade IB in the vertical direction. A door is attached to one blade of the upper tubular support 2B, and the blade IB of the lower tubular support 2B is fixed to a pillar or the like.

In the hollow part of the tubular support part 2B, a common slide shaft 8 is installed "without play", and the slide shaft 8 connects the tubular support part 2B to the blade part 1B. The two tubular support parts 2B are fitted in such a way that they can slide vertically inside the two tubular support parts 2B. and,
The slide shaft 8 has a slide groove 5 cut into a deep groove shape at the upper end, and a fixing pin 6 fixed across the two tubular bearings is fitted into the slide groove 5. , the slide shaft 8 extends along the slide groove 5 into the tubular support portion 2.
It can slide relative to a person, and together with a stone, the tubular support rotates in conjunction with two people.

On the other hand, at the lower end of the slide shaft 8, the biasing door is attached along the axis 2, and a coil is placed between the head 8 of the biasing door and the stepped portion 9 in the hollow of the tubular support 2B. p spring 1
0 is mounted in a compressed manner, and the slide shaft 3 is always biased toward the lower end of the tubular support portion 2B.

Further, a locking pin 12 is provided in a transverse manner in the intermediate portion of the slide shaft 8, and has both ends protruding from both side surfaces of the slide shaft 8. The slide shaft 3 is always pressed against the upper edge by the biasing force of the coil spring 10, and is slidable vertically within the tubular support 2B.
It is configured to be rotatable relative to B.

A storage notch 13 for storing both end portions of the locking pin 12 is formed at the lower edge of the two tubular bearings that are in contact with the upper edge of the tubular bearing 2B. The opposite edges of the frame 2B are always in contact and joined as shown in FIG. 1). And the joined tubular support part 2B
On the upper edge, as shown in Fig. 2, when the blade part IAIB opens relatively and the door reaches the required opening angle θ (the opening angle shown is 90''), there is a tubular support part. A locking groove 14 is formed to receive approximately the lower half of both end portions of the locking pin 12 of the slide shaft 8 that rotates in conjunction with the two people.

Note that the biasing force of the slide shaft 8 is due to the rotation of the biasing force door! It can be freely adjusted by adjusting the compression height of the spring 10. In addition, 11 in the figure is a washer attached between the coil spring 10 and the stepped part 9, 15 is a plug attached to both ends of the tubular support part 2A2B, and 16 is a screw for fixing the blade part IAIB to a door etc. It is a hole.

In the hinge of the present invention having the above configuration, the locking groove 14 has a diameter of 90 mm, for example.
If it is formed to correspond to the required opening angle of the door, such as 180", for example, when the door attached to one blade is opened, the blade IA can be rotated relative to the blade IB fixed to the pillar side. When this happens, the slide shaft 3 rotates in conjunction with the tubular support 2A on the blade IA side while being biased toward the tubular support 2B on the blade IB side, and both ends of the locking pin 12 are connected to the tubular support 2A on the fixed side. It slides in pressure contact with the upper edge of the support portion 2B.When both ends of the locking pin 12 reach the position of the locking groove 14, the slide shaft 8 is swiped by the biasing force of the coil Y spring 10, and the second As shown in the figure, the locking pin 12 horizontally installed in the middle part of the coil spring 10 fits into the locking groove 14.The locking pin 12 fitted into the locking groove 14 then Since it receives a biasing force, it is possible to lock the required opening position of one blade, that is, the required position of the door.The locking action of the door is achieved by the sliding action due to the biasing force of the Sphiid shaft 8. Therefore, even when the door is opened, closed, and locked, the relative spacing between the illustrated blade portions IAIB is always maintained constant, and
The two upper tubular supports can be assembled and connected by simply inserting them from above the slide shaft 8 that has been previously attached to the lower tubular support 2B, making it easy to remove and install doors installed at building entrances, etc. Not only is it simple and easy to repair and replace, but it also has the unique effect of allowing one-touch assembly on-site by separating the blade parts IAIB and attaching them to doors and pillars individually when newly installed.

In addition, when closing the door that is locked at the required opening position as shown in Figure 2, the locking pin 12 is rotated by the rotational force of the door.
It separates from the lock @14 against the biasing force of the spring 10.

In the above structure of the present invention, a plurality of locking grooves 14 are used to lock the door in multiple stages such as 45° and 90°, or a ring-shaped locking groove is formed in the tubular support portion 2M or 2B. A cover may be fitted so that the storage notch 13 and locking groove 14 are not visible from the outside.

"Effects of the Invention" As explained above, the hinge of the present invention has a locking action by the locking pin 12 and the locking groove 14 at the required opening position of the door, so that the opened door is protected from wind. There is no risk of the door moving due to vibration and becoming half-open, closed, or slamming, and the opening position of the door is stable. Since the open position can be automatically locked only by the door opening operation, the trouble of hooking on conventional fasteners is eliminated, and the door opening operation becomes extremely simple.

Furthermore, since there is no need to provide accessories such as fasteners near the door, there are advantages in that there are no obstacles during passage, the door structure is simplified, and the door installation work is simplified.

Furthermore, since the hinge of the present invention simplifies the separation and connection of the two tubular support parts 2B, it becomes easier to install the hinge and the door when installing the door, and it is extremely easy to maintain, inspect, and replace the door and the hinge. It has excellent effects such as
