Abstract

PURPOSE:To open or close a door in an automotive manner by winding an A plate, serving as a fulcrum at the pole side and provided with a projection zone spiraling downward, and a B plate, provided with an upward projection zone being fitted in the former at the door side, together with each other into coalescence. CONSTITUTION:A hinge is composed of an A plate serving as a fulcrum at the pole side winding on an axial rod 1 and a B plate operating as attached to the door side. Then, a projection zone 2 spiraling downward is installed in the A plate, and another projection zone 2 spiraling upward in the B plate, respectively. Next, as for each one intertwining both these projection zones 2, 3 with each other, the A plate is attached to the pole side in a closed state, and the B plate to the door side, respectively, and these plates are unified in one with the axial rod 1 as the center. With this constitution, when the door is opened, the projection zone 3 of the B plate uplifts little the projection zone 2 of the A plate by the angle whereby some shift is produced there, and this shift is able to generate such an action as closing the door automatically with its own weight.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a door natural closing hinge that allows an opened door to close naturally.

(b) Conventional technology Until now, the role of hinges was merely to open and close doors. In addition, a separate door check was required to close the opened door. This was not only expensive but also very annoying.

(c) Problems to be solved by the invention Conventionally, the hinge for opening and closing the door and the door check for closing the door have had separate functions. The problem lies in how to make these separate functions work simultaneously using just a hinge.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the door self-closing hinge according to the present invention is made as follows. In other words, the shaft α that is combined as a hinge)
In this section, plate A, which serves as the fulcrum on the pillar side, was provided with a downward spiral, and plate B, which operates on the door side, was provided with an upward spiral. The spiral parts of A plate and Bi are intertwined alternately and combined, and in the closed state, the A plate and B plate are aligned at the same height, and the A plate is attached to the pillar side and the B plate is attached to the door side. .

In this manner, when the door is opened, the spiral portion of the plate B rises above the spiral portion of the plate A due to the angle, and the door is slightly raised. The door is made to close naturally by utilizing the downward force of the weight of the door itself to compensate for this upward deviation.

(E) Function The door natural closing hinge according to the present invention can be used to close an open door naturally by opening it from the left or right side of the hanging base, or opening inward.
The spiral angle is reversed due to outward opening. To install this, choose the one that meets the conditions, when the door naturally closes and the hinge is opened, the lower side should be attached to the pillar side with plate A, and the upper side should be attached to the door side with plate B. . Furthermore, the closing speed is related to the condition of the helical angle, the weight of the door, or the resistance of the spiral parts of the A plate and the B plate against each other.

(F) Example Example 1 Figure 1 shows the basic shape of the A and B plates that serve as the base. FIG. Cut along this solid line and
Make a board and a B board. The left side of this is the fulcrum side A plate for pillar mounting, and the right side is the actuating side B plate for door mounting. The dotted line is the bending line to narrow the gap between the pillar and the door due to the thickness of the shaft rod.
Round holes are drilled with screw holes for installation. At this time, the length, width, and angle of the A-plate protruding band (2) and the B-plate protruding band (■) wound around the shaft 0) are determined by the circumference of the shaft 0), but these A The tip of the protruding band ■ on the board should be connected in between to the starting point of the next lower protruding band ■ on the same A plate, or the tip of the protruding band ■ on the B plate should be connected to the starting point of the next lower protruding band ■ on the same B plate. When winding each shaft rod 0) so that it connects to the starting point of the protruding band (2) in the middle, the angle and dimensions are such that the tip reaches the position where it connects to the next starting point of the same plate.

Figure 2 is the protruding band (2) of A plate made based on Figure 1.
It is a perspective view with the shaft rod 0) removed, with the protruding band (3) of plate B combined and wound around the shaft rod 0). This is done by inserting plates A and B into each other according to the angles of their protruding bands, so that they intersect, and AN protruding band (2) and B plate protruding band ■ come out on the same plane. If they are rolled at the same time according to step 1), they will become intertwined with each other alternately and coalesce into a spiral shape as shown in the figure. By combining in this way, it becomes one automatic door closing hinge that can function even without the shaft rod 0).

FIG. 3 is a closed perspective view of a completed door that naturally closes with the door opening outward from the left hanging base or opening inward from the right hanging base. In this state, it is convenient to align the fulcrum side A plate and the operating side B plate at the same height.

FIG. 4 is a perspective view of the closed door of FIG. 3 with the self-closing hinge opened 90 degrees. At this time, the fulcrum (plate B on the operating side from the IFIA plate spirals up by the angle at which the door opens, creating a step. This allows the length of the shaft rod 0 to be adjusted depending on the angle at which the door is opened).

FIG. 5 is a cross-sectional view showing the position of the door self-closing hinge attached to the pillar and the door, with the door closed and opened.

Example 2 Figure 6 is the reverse basic form of Figure 1, with the door opening outward from the right hanging base.
Or an inside plan view of the left hanging base that opens inward. In this case, the right side is the fulcrum side A plate for the pillar attachment, and the left side is the actuation side B plate for the door attachment, which is different from Figure 1 of Example 1. Both protruding belts ■ and ■
is the opposite angle. Other differences are left and right, inside and outside, but Example 1
It acts according to the following.

The above is one embodiment of the present invention.

(G) Effects of the Invention When the door has a natural closing hinge according to this invention, just by attaching this hinge, the door can close naturally even if it is left open, without having to close the opened door every time. It's convenient, hassle-free, and most of all, it's cheaper than before, and it looks better.

Claims (1)

[Claims] 1. Of the two bases constituting the hinge, the side that will be the fulcrum is A.
plate, and the operating side is plate B. The protruding bands wound around both shaft rods (1) are an A-plate protruding band (2) and a B-plate protruding band (3), which are formed at a predetermined oblique angle. The angle leading to the tip is the protruding band of plate A (2
) is at a downward angle, and at the projecting band (3) of plate B, it is at an upward angle. The protruding bands (2) and (3) are cut out alternately in a concave and convex shape and are provided so as to fit together. In other words, the protruding belt between plate A and plate B (2)
The protruding directions of (3) and (3) are such that they face each other and interpose each other. The protruding band (2) of plate A and the protruding band (3) of plate B are loosely fitted around the shaft rod (1) at the same time. The door naturally closes with a hinge made of this structure.
