うこともあつた。 However, in conventional gravity hinges of this type, most of the load of the door is received by the horizontal plate of the L-shaped base plate in the lower support via the lower pivot, so the horizontal plate bends downward. It could bend and deform, making it difficult to open and close the door, and even cause the part to break.

嵌挿させたことを特徴とするものである。 The gravity hinge reinforcing device of this invention was proposed to reinforce the L-shaped base plate of the lower support and increase the durability of that part. An upper pivot fixture that fits together and is attached to the door side, a lower support fixture that has an L-shaped board that is attached to the fixed member side, and a lower pivot fixture that rotatably fits thereto and is attached to the door side. In the gravity hinge, a concave portion is provided on the bottom surface of the horizontal plate portion of the L-shaped substrate of the lower support, and
It is characterized in that the upper end of the support body whose lower end is fixed to the floor surface is fitted into the recess.

より、その支持体５を床面Ｆに固定してある。 In the present invention, a recess 34 having a circular, square or other arbitrary planar shape is provided on the bottom surface of the horizontal plate portion 31b of the L-shaped base plate 31 of the lower support 3. As shown in the illustrated example, the recess 34 can be provided directly below the cylindrical body 32, which serves as the point of application that receives the load of the door B, and preferably concentrically with the cylindrical body 32. The upper end of the support 5 whose lower end is fixed to the floor surface F is fitted into the recess 34.
The support body 5 is made of metal, hard synthetic resin, or the like, and it is desirable that its cross-sectional external shape correspond to the planar shape of the recess 34 . In the illustrated example, the support body 5 is formed of a circular tubular body, and has an integrally attached flange 5a at its lower end. The support body 5 is fixed to the floor F by fixing the flange 5a with screws 6.
支持体５を中空の管状体にした理由は、一つに

示例に限るものではなく、例えば中実の柱体を用
いてもよい。また、支持体５の床面Ｆに対する取
付け手段も、フランジ手段に限らず、埋設手段そ
の他任意の固定手段を用いてよい。 The reason why the support body 5 is made into a hollow tubular body is that it can be easily cut according to the installation distance between the bottom surface of the horizontal plate portion 31b of the L-shaped substrate 31 and the floor surface F; The other one is the horizontal plate part 31b.
This is to prevent the deformed bulge 33a from getting in the way when the lower end of the shaft rod 33 is caulked in the recess 34 of the support body 5, but the form of the support body 5 is not limited to the illustrated example. For example, a solid column may be used. Further, the means for attaching the support body 5 to the floor surface F is not limited to the flange means, but may be any other fixing means such as embedding means.

させるに極めて有効である。 Although the gravity hinge reinforcing device of this invention described above has an extremely simple structure, the horizontal plate portion 31b of the L-shaped base plate 31 in the lower support 3, which receives most of the load of the door B, is the support. Since the displacement of the upper end of the support body 5 is restrained within the recess 34 of the horizontal plate portion 31b, the load from the door B can be reliably received, improving the durability of the gravity hinge. It is extremely effective for
