2. Description of the Related Art A device for covering a shaft barrel beautifully by covering the shaft barrel with a hinge is one in which a truncated cone-shaped cap is covered on the shaft barrel (Japanese Utility Model Publication No. 4117052). One in which a pipe is fitted into a barrel (Jpn. Pat. Appln. KOKAI No. 48-278), one in which the bottom of a door hinge cover is provided with water drain (Publication No. 3-19587), and one in which a deformed cap is fitted to the barrel. (Jpn. Pat. Appln. KOKAI Kaihei No. 3-23581), and the like.

[0003]

[Problems to be Solved by the Invention] In the case where a truncated cone-shaped cap is covered on a shaft cylinder, it is difficult to bend the shaft cylinder into a conical shape when a steel plate is used as a material, and other than the cast hinge. It could not be applied to. In addition, the lower conical cap has a structural defect that it is easy to fall off. Note that the gap between the cap walls is made in the diameter direction of the cap, as seen in the figure in the gazette, so when the cap is fitted to the barrel, the fit between the blade surface and the cap edge is poor. , Especially when the boundary between the barrel and the blade is slightly curved (called swage type Swaged), or when the blade is tangential to the barrel (called Flat Flat Bac k). However, there was a step between the edge of the cap wall and the surface of the blade, which impaired the appearance. The structure in which the decorative pipe was fitted into the barrel was for the purpose of decorating only the barrel, and the end of the barrel remained the same as the conventional star-shaped structure. A hinge cover with drainage is a cover that covers the hinges of outdoor vehicles such as automobiles to prevent rain and dew.It has a poor appearance and is unsuitable as a door hinge in general construction. It was Also, in the case where the deformed cap is fitted to the shaft cylinder, the lower cap may loosen and fall off due to vibration during opening and closing of the door, and the cap is fixed to the shaft cylinder with, for example, an adhesive to prevent the cap from falling off. It was necessary to prevent it. Also, the upper cap could rise while the door was in use. In addition, the cap of this shape has a part where the cap and the cylinder are not in tight contact with each other and the thickness of the cap is thin, so that it easily deforms or breaks when an object hits, and the appearance is There is a drawback that it damages.

[0004]

[Means for Solving the Problems] By compensating for the above drawbacks, a hinge cap that has a simple structure and a good appearance, the cap does not fall off during use, and the tensile strength of the hinge also increases They are trying to supply the used hinges at low cost. For that purpose, the following means were used. A locking groove is provided at one end of the shaft barrel of the hinge, and a locking projection provided on the inner surface of the opening end of the cap side wall of the shaft barrel and having a height smaller than the thickness of the hinge blade engages with this locking groove. The relative positions of the locking groove and the locking projections were determined when fitting. The inner diameter of the shaft cap is the same as the outer diameter of the shaft of the hinge, the inner diameter of the housing is the same as the height of the shaft, and the inner diameter is equal to the outer diameter of the shaft of the hinge. And the shaft core accommodating cavity, and the shaft cylinder accommodating cavity and the shaft core accommodating cavity are communicated with each other. The depth of the housing space of the barrel cap and the height of the gap provided in the side wall are made equal to the height of the barrel, respectively. In addition, the opening direction of the air gap was set to be a tangential direction to the inner wall of the shaft cylinder cap.

[0005]

[Operation] A locking groove is provided at one end of the shaft barrel of the hinge, and a locking projection having a height smaller than the thickness of the hinge blade provided on the inner surface of the opening end of the side wall of the shaft cap is provided in this locking groove. The relative position between the locking groove and the locking projection was determined as if they were engaged. Therefore, when the shaft cap is fitted onto the shaft cylinder while inserting the base of the blade into the space of the shaft cap, the locking projections on the inner surface of the cap will rub the shaft surface at first, and the cap will be completely removed. When it goes into, it snaps into the locking groove of the barrel to prevent the barrel cap from falling off. In addition, the inner diameter of the shaft cylinder cap has an inner diameter equal to the outer diameter of the shaft cylinder of the hinge and a depth equal to the height of the shaft cylinder, and an inner diameter equal to the outer diameter of the shaft core of the hinge. Since the shaft cylinder housing cavity and the shaft core housing cavity are made to communicate on the same line, when the shaft cylinder cap is externally fitted to the shaft cylinder, the open end of the shaft cylinder cap is It matches well with the lower end of the barrel, and the upper end of the shaft enters the shaft cavity. Also, because the opening direction of the air gap is tangential to the inner wall of the shaft cylinder cap, when the boundary between the shaft cylinder and the blade is slightly curved (swage type), the blade is tangential to the shaft cylinder. In both cases (flat-back type), the contact between the edge of the side wall of the void and the surface of the blade is good.

The hinges of the type shown in the figure are commonly known as biaxial hinges, French hinges, pommel hinges, etc. There is a functional distinction between "right hand" and "left hand", and the one shown in Fig. 1 is Although it is a "left-handed" hinge in which the left-hand blade of the hinge is attached to a pillar, Fig. 4 shows an enlarged view of the main part of the "right-handed" hinge to facilitate illustration. The column barrel (3) is wound in the same body as the column blade (1), and the door barrel (4) is wound in the same body as the door blade (2). The lower part of the shaft core (7) is vertically fixed to the shaft cylinder cavity (6) of the column shaft cylinder (3), and the upper part of the shaft core (7) is the shaft cylinder cavity (4) of the door shaft cylinder (4). 6), and the upper end of the shaft core (7) projects above the columnar cylinder (3). The shaft cylinder cap (5) is a cylindrical body having a closed head (8) and an opening (9) at the other end, and has a shaft cylinder housing cavity (10) and a shaft core housing cavity (11) inside. And are continuously provided in this order from the end of the opening (9). The shape of the shaft cylinder housing cavity (10) is such that the inner diameter is equal to the outer diameter of the shaft cylinders (3) and (4), and the depth (D) is the length (H) of the shaft cylinders (3) and (4). equal. The shape of the shaft core housing cavity (11) is such that the inner diameter is equal to the diameter of the shaft core (7) and the depth thereof is the protruding portion (12) of the shaft core (7) protruding from the barrel (3) (4). Made deeper than the length of. It is a regrettable that the shaft cylinder housing cavity (10) and the shaft core housing cavity (11) are provided in the shaft cylinder cap (5) coaxially with the center line of the cap. In the side wall (13) of the shaft cap (5), a space (14) through which the blades (1) and (2) are to be inserted is opened in the vertical direction in parallel with the center line of the cap (5). The height (h) of the space (14) is equal to the height (H) of the barrel (3) (4), the width thereof is substantially equal to the thickness of the roots (1) (2), and the space (14) is The opening direction of (14) is tangential to the inner wall (15) of the shaft cap (5). Next, a locking projection (17) is projected inside the opening end (16) of the shaft cap (5). The inward projection size of the locking projection (17) is smaller than the thickness of the blades (1) and (2). The size of the locking projection (17) is smaller than the size of the locking groove (18) provided in the barrels (3) and (4). The position of the locking groove (18) is such that when the shaft cylinder cap (5) is fitted into the shaft cylinder ((3) (4) and finished, the locking projection (17) is locked by the locking groove (18). (19) is a fixing pin for fixing the shaft core (7) to the column barrel (3), and (20) is a washer. In order to manufacture the cylindrical cap (5), the cap (5) that has been completed can be manufactured from the mold in either case of injection molding a plastic material or by metal die casting. The position of the locking projection (17) is set as close as possible to the gap (14) so that it can be easily removed, so that the vicinity of the side wall (13) of the shaft cap (5) where the locking projection (17) is located. Since there is a gap (13), it is easy to soften, so the completed cap (5) can be easily removed from the mold. In the manufacturing process of the hinge, the position of the locking groove (18) that does not hinder the winding work of the barrel (3) (4) is as shown in FIG. ) (4) is near the turning point.

[0007]

[Effects of the Invention] Since the hinge of the present invention is configured as described above, it has the following effects. Hinging blades (1) provided on the inner surface of the opening end (16) of the side wall (13) of the shaft cap (5) are provided with locking grooves (18) at the edges of the shaft shafts (3) (4) of the hinge. ) As the locking projection (17) having a height smaller than the thickness of (2) engages with the locking groove (18), the locking groove (18) and the locking projection (17) are Since the relative position of the shaft cylinder cap (5) is fitted outside the hinge cylinder (3) (4), the locking projection (17) of the shaft cylinder cap (5) is 3) Since it is engaged with the engaging groove (18) of (4), the cap (5) of the barrel does not come off from the barrel even when the hinge is opened and closed. The inner diameter of the barrel cap (5) is equal to the outer diameter of the hinge barrel (3) (4) and the depth (h) is equal to the height (H) of the barrel (3) (4). And a shaft core housing cavity (10) having an inner diameter equal to the outer diameter of the shaft core (7) of the hinge. The cavity (11) communicates with the center line of the barrel cap (5) and the height (h) of the void (14) provided in the side wall (13) is the height of the barrel (3) (4). Since the shaft cylinder cap (5) is externally fitted to the shaft cylinders (3) and (4), the protrusion (12) of the shaft core (7) is accommodated in the shaft core housing cavity (11). Since the side wall of the shaft cylinder head (8) holds the protrusion (12) from the side, a shaft core having a longer protrusion (12) is used as compared with a general shaft core. Has the same effect as the old hinge. Compared to conventional hinges that use a shaft core of the same length as the shaft cylinders (3) and (4), the "tensile strength" of the hinge (counts the force to pull both blades of the hinge horizontally). There is a feature that strength) is larger. Since the opening direction of the space (14) is tangential to the inner wall (15) of the shaft cap (5), the boundary between the hinge shaft cylinder (3) (4) and the blades (1) (2) is Any type of hinge, such as a lightly curved swage-type blade hinge or a flat-back type blade hinge in which the blades (1) and (2) are tangential to the shaft cylinders (3) and (4). On the other hand, there is a feature that the edge of the side wall of the void (14) is well fit to the surface of the blade, there are few steps, and the appearance is extremely good. In the shaft cylinder cap (5) of the present invention, the entire cap is in intimate contact with the shaft cylinders (3) and (4), and there is no space between the cap and the shaft cylinder. It does not have the drawback of being deformed, and has the characteristic that it can withstand long-term use and maintain its aesthetic appearance.
