Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applied to the sliding part of the shaft part corresponding to the pipe part of the slat panel, which is used in particularly heavy doors such as doors and doors that open and close. This invention relates to a new type of ball flag hinge (hereinafter simply referred to as a hinge) that incorporates a ball.

(Prior art) Conventionally, a flag hinge used for a heavy door, etc., is constructed by combining the pipe parts 33 and 34 of the left and right slats 31 and 32, as shown in FIG. Part 3
By inserting the shaft core 35 into 3 and 34, both blade plates 31,
32 is rotatably held. Reference numeral 36 denotes a rotating member containing a ball attached to sliding parts of both the tube parts 33 and 34, and 37 denotes a rotation member of both the tube parts 33 and 34.
The pseudo-jewel attached to the open end of the
Screw holes used to fix 1 and 32 to the target object,
39 is a flag hinge.

This flag hinge 39 fixes the left wing board 31 to a wall, door frame, etc. with screws etc. through each screw hole 38,
It is used by fixing the right wing plate 32 to one end of a door or the like.

(Problems to be Solved by the Invention) The flag hinge 39 is made of a thick material so that it can withstand the weight of a door or the like. Therefore, it is extremely difficult to form the tube portions 33, 34 at one end of the slats 31, 32 in terms of machining, and there is a drawback that the machining costs are high and the flag hinge 39 is expensive.

On the other hand, if you make the wall thickness thin enough to make it easier to work with,
Since it will not be able to withstand the weight of the door etc.
Weld the ends 40 of 3 and 34 to the blade plates 31 and 32 4
1, but this time the welding became very difficult and the processing cost was high, and in the end, the flag hinge 39
becomes expensive.

(Means for Solving the Problems) The present invention has been made by focusing on such conventional problems, and by examining flag hinges from a new perspective, The purpose of the present invention is to solve the above problems by creating a new type of structure that does not require .

The present invention provides an upper shaft plate having an upper ball receiving plate extending downwardly from the upper part of one end in the width direction of a member main body, and an upper ball receiving plate and an end of the upper shaft plate. One blade plate having an upper shaft portion formed by molding synthetic resin around the body; and an upwardly protruding lower blade plate extending symmetrically to the upper shaft plate at the lower part of one widthwise end of the main body of the other member. The other blade plate is attached to the lower shaft plate provided with the ball receiving plate, and the lower shaft portion is molded from synthetic resin in the same manner as the upper shaft portion; the upper and lower shaft portions are attached through the upper and lower ball receiving plates. With a steel ball interposed between the upper and
This hinge is characterized by connecting both ends of the lower part with a connecting tube.

(Function) The hinge is extremely easy to manufacture, as both of its slats do not require tubes unlike the slats of conventional flag hinges, and can be made by simply punching them out of a flat plate material. Unlike flag hinges, there is no need for difficult processing to fix the imitation orb to the open end of the tube, and the upper and lower shaft parts are simply formed on both shaft plates using synthetic resin suitable for mass production, significantly reducing the manufacturing man-hours. Can be reduced.

Furthermore, since the hinge is rotated by a ball interposed between the upper and lower shaft portions, it can be opened and closed very smoothly, has little wear, and has a very long life.

Furthermore, the hinge has a unique shape that is not seen in conventional flag hinges, and is made of synthetic resin and has a colorful appearance, giving it a completely different appearance, which stimulates customers' desire to purchase it.

(Embodiment) The present invention will be described in detail below based on FIGS. 1 to 6 showing one embodiment thereof. 1 has an upper ball receiving plate 3 cut out in a semicircular shape at the center of the tip at the upper end of one side in the width direction of a member main body 2 made of a rectangular plate of a required thickness, and is spaced at a predetermined distance from the member main body 2. This member is a right wing board member in which an upper shaft plate 6 having a rectangular upper ball receiving plate 5 protruding downward from the shaft plate main body 4 extends in a predetermined width in the width direction parallel to the member main body 2. A plurality of mounting holes 7 are bored at required locations in the main body 2. Note that an axis X is set parallel to one side end of the member main body 2 and passing through the center point a of the upper ball receiving portion 3. Further, a small uneven surface 4' is carved on the outer end surface of the shaft plate main body 4 above the upper ball receiving plate 5.

Reference numeral 8 denotes an upper ball receiving plate 5 and a bearing body 4 connected to the upper ball receiving plate 5 so that the surface of the upper ball receiving portion 3 is exposed and a substantially hemispherical concave portion including the upper ball receiving portion 3 is formed. The circumference near the end of the axis
The right wing plate is formed into a cylindrical shape with the center line at the top and is formed by molding synthetic resin such as nylon to form the upper shaft part 9, and the upper shaft part 9 around the upper ball receiving plate 5.
The diameter of the lower part is smaller than that of the upper part to form the upper connecting part 10.
is formed.

Reference numeral 11 denotes a left slat member 11 which is arranged symmetrically to the right slat member 1 by turning back the top and bottom of the right slat member 1 shown in FIG. , a lower ball receiving plate 13 having a semicircular notch at the center of the tip and a rectangular lower ball receiving plate 15 projecting upward from the shaft plate main body 14 at a predetermined distance from the member main body 12; The shaft plate 16 is made to extend in a predetermined width in the width direction on the same side as the right slat member 1 and parallel to the member main body 12, and
A plurality of mounting holes 17 are drilled at required locations. Note that an axis x' is set parallel to one side end of the member main body 12 and passing through the center a' of the lower ball receiving part 13. Further, like the upper shaft plate 6, a small uneven surface 14' is carved on the outer end surface of the lower shaft plate 16.

Reference numeral 18 designates a lower ball receiving plate 15 and a lower ball receiving plate 15 so that a steel ball 21 is fitted into the lower ball receiving portion 13 to expose a spherical surface slightly smaller than the hemisphere of the ball 21 and to be held rotatably. The left wing plate is formed by molding synthetic resin into a cylindrical shape so that the center line is on the axis X', forming a lower shaft part 19 near the end of the shaft plate main body 14 connected to the lower ball. The diameter of the upper part of the lower shaft part 19 around the receiving plate 15 is made smaller than that of the lower part, and the lower connecting part 20 is formed to have the same diameter as the upper connecting part 10. A projection 22 is provided.

Reference numeral 23 denotes a connecting pipe having an inner diameter slightly larger than the outer diameter of the upper and lower connecting parts 9 and 19, and has a locking hole cut out so that the protrusion 22 of the lower connecting part 19 fits into one of the open ends. 24 are provided.

25 fits the locking hole 24 into the protrusion 22 and inserts the connecting pipe 23 into the lower connecting part 20, and then inserts the upper connecting part 10 into the connecting pipe 23, and then connects the upper and lower shaft plates 6, This is a hinge in which the left and right wing plates 8, 18 are connected by aligning the axes X and X' of 16.

This hinge 25, like a conventional flag hinge, fixes the left wing board 18 to a wall, door frame, etc. through each mounting hole 7 with screws, etc., and fixes the right wing board 8 to one end of the door, etc. used.

In this case, the hinge 25 has both wings 8, 1
8 does not require a tube part like the slats of a conventional flag hinge, and after punching out a flat plate material, the double shaft plates 6, 1
It is extremely easy to manufacture because it only requires bending the base of the plate (the conventional one requires three or more steps, and the processing work is very difficult when the thickness of the plate becomes hot, but the one of the present invention) Furthermore, unlike conventional flag hinges, there is no need for the difficult processing of fixing the artificial jewel to the open end of the tube, and the upper and lower shaft plates 6 and 16 are made of synthetic resin suitable for mass production. Since the lower shaft portions 9 and 19 are simply molded, the number of manufacturing steps can be significantly reduced.

In addition, since the hinge 25 rotates via the balls 21 held in the upper and lower ball receiving parts 3 and 13 provided on the upper and lower ball receiving plates 5 and 15, the opening and closing of the hinge 25 is extremely smooth, and wear is prevented. It has a very long lifespan. Even after applying a load of 35 kg to the hinge 25 and performing an opening/closing test 300,000 times, no abnormality occurred.

Furthermore, the hinge 25 has a unique shape that is not seen in conventional flag hinges, and is made of synthetic resin and has a colorful appearance, giving it a completely different appearance, which stimulates the consumer's desire to purchase it.

In the above embodiment, the left and right slats 8, 1
8, the upper and lower shaft plates 6, 16 are bent at their bases so that they are parallel to the member bodies 2, 12, but depending on the purpose of use, they may be formed as flat plates without being bent.

Furthermore, although the upper and lower shaft plates 6 and 16 are each provided with a step on the outside, if necessary, the shaft plate may be shaped as shown by the two-dot chain line in FIG. 6A without providing this step. In addition, in order to increase the adhesive strength between the synthetic resin and the upper and lower shaft plates 6 and 16, small uneven surfaces 4' and 14' were carved on the outer end surfaces of the upper and lower shaft plates 6 and 16. Upper and lower shaft plates 6, 1 covered with synthetic resin
It is also possible to form an appropriate number of through holes at 6 locations.

Furthermore, the upper and lower shaft parts 9 and 19 are made of synthetic resin and are formed into cylindrical shapes, but they have the necessary adhesive strength with the upper and lower shaft plates 6 and 16, and also hold the ball 21 securely.
As long as it can withstand the load of a door, etc., it does not necessarily have to be cylindrical, but may have a polygonal cross-section, for example.

Further, a protrusion 22 is provided at the lower end of the lower connecting portion 20, and a locking hole 24 is provided in the connecting pipe 23, so that the connecting pipe 2
3, but the protrusion 22 and the locking hole 24 are removed, and the connecting pipe 23 is connected to the lower connecting part 20.
It may be fixed with an adhesive or the like.

The lower shaft part 19 was formed by inserting the ball 21 into the lower ball receiving part plate 13 and molding the synthetic resin so as to expose a slightly smaller spherical surface than the hemisphere of the ball 21. It may be formed similarly to the upper shaft portion.

(Effects of the Invention) Since the present invention has the above configuration, it has the following effects.

(1) Both vanes can be manufactured by simple press processing without the need for pipe parts, and the shaft part can be formed by synthetic resin molding suitable for mass production without using a shaft core, so the processing man-hours can be significantly reduced. It contributes to reducing the cost of products and can be supplied to customers at low prices.

(2) Since it has a unique shape not found in conventional flag hinges and colorful colors made from synthetic resin, it stimulates customers' desire to purchase and contributes to increased sales.

(3) Since it is rotated by balls held in the upper and lower shafts, opening and closing are extremely smooth and it has an extremely long life.
