Description

The present invention relates to a pivot hinge that can be used regardless of the door opening / closing direction.

When the main component of the open / close device attached to the opening is a door, the frame around the opening and the door are connected by a hinge (called hinges, hinges, hinges, etc.) and the door is rotated. Hold freely. The hinges can be roughly classified into two types based on the positional relationship between the flat plate used for connecting the frame and the door and the shaft. One is the blade plate surface and the shaft connected in parallel, and the two blade plates are connected to the butterfly around the shaft. There is a type called a pivot that opens and closes like this, and the other type is called a pivot in which the support plate surface and the shaft are cross-connected at right angles, and the two support plates move in a plane around the shaft.

The butterfly shape is attached using either the left or right vertical joint of the frame and the door. Two metal doors and two or three wooden doors are used. The pivot type is attached using the upper and lower joints of the frame and the door, and two pieces are used regardless of whether they are made of metal or wooden. In both cases, the shaft at the center of rotation is used at a position slightly away from the joint, but the butterfly type has the ability to support the load of all hinges, while the pivot type has the load of the lower hinge of the door. The support upper hinge prevents the door from falling down and serves as a guide for rotation. Patent Document 1
Discloses a technique for using interchangeable parts for the upper and lower pivot type hinges.

The door is divided into a left opening and a right opening at the hinge mounting position, and further divided into an inner opening and an outer opening at the place where the door is used. When viewed from the hinge side, the hinge attached to the left end of the door is called the left suspension base, the hinge attached to the right end of the door is called the right suspension base. Become. Therefore, there may be a case where a plurality of types of reverse types are required for the hinge depending on the opening / closing direction of the door to be used.

A flat head screw is used to attach the butterfly hinge and the pivot hinge. In the case of a butterfly hinge, the right and left slats are not symmetrical in the even type, but there is no need for mistakes. However, in any case, the processing content to be applied to the slats is such that a hole is formed in the flat plate and the roundness is determined. In the case of the pivot type hinge, the processing content required for the support plate corresponding to the blade plate is to make a hole in the flat plate and bend it, but the shape is more complicated than the blade plate, and the weight and rotation of the door are at the tip of the support plate. It can not be solved as easily as a butterfly shape because it is supported by the attached bearing.

Although Patent Document 1 uses compatible members for the upper and lower pivot type hinges, it is expected that there are many components and it takes time and effort for assembly and adjustment. Moreover, it does not touch on the case where the door opening and closing directions are different. Applicants trial and error to solve the combined problem when opening and closing direction of the pivot type hinges are different, minimizing the component count increases the commonality and compatibility with other members fastened to freely difference member part For this reason, we have developed a left / right hinge that can be used only by changing the mounting position.

In the present invention, the configuration of the pair of pivot hinges used for the door of the opening / closing device is such that each member shape of the support plate main body of the frame side support plate and the support plate main body of the door side support plate is different, and other members are shaped. When the structure and dimensions are the same to improve commonality and compatibility, and a pair of hinges assembled using these members is installed by selecting either side around the opposite ends of the diagonal connecting the four corners of the door, the door This is a left and right pivot hinge that can change the opening and closing direction of the.

The pivot type hinge of the present invention moves the position of the left and right hinges along the diagonal of the door when the left and right hinges used for the left door is used for the right door. Then, it is an easy-to-handle hinge that is used for right-hand hanging when attached to a required position by reversing the direction of the hinge. In this way, the left and right hinges that do not require any mistakes reduce the burden of inventory, and the reduction in the number of components, the commonality, and compatibility have also been effective in reducing manufacturing costs.

According to the present invention, in an opening / closing device using a pivot type hinge, at least two sets of hinges used for a door are constituted by a small number of members, and the shape, structure and dimensions are made the same for each member. Apart from making the support plates attached to the side and door side different, the shaft, bearing jacket, and cylindrical bearing are made common and compatible, and can be used for doors with different opening and closing directions by changing the hinge mounting position. A structure that can be used. The assembly contents required for setting the positional relationship of the hinge constituent members are not so small, and the necessary functions can be easily provided. The installation work at the site can be done by one worker with a simple tool.

Necessary functions of the hinge used for the door are that the lower hinge supports the door's own weight with a shaft and a bearing so that it can rotate freely, and the upper hinge holds the shaft and the bearing while preventing the door from falling down. In addition, in any hinge, the shaft and the bearing are securely fitted to prevent the door from falling off. In addition, when the door is supported by the lower hinge and the positional relationship between the notch of the bearing jacket of the upper hinge and the cylindrical bearing is adjusted so that the shaft is removed from the notch, the door can be easily removed from the hinge. It can be safely attached and detached.

When using two sets of hinges for doors with different opening and closing directions (different usage), move the upper hinges down and the lower hinges up so that they move along the diagonal line connecting the four corners of the door. Change and install. The adjustment work required for each hinge is to move the cylindrical bearing fitted to the shaft in a direction in which the notch of the bearing outer casing closes. The three-way position adjustment means when installing the hinges are the insertion of a thin plate on the top and bottom and the movement of a cylindrical bearing on the support plate, the insertion of a thin plate on the left and right, and the long hole provided on the support plate on the front and back To make fine adjustments.

As shown in FIG. 1, two sets of pivot type hinges 7.8 used in the opening / closing device 1 include a frame-side support plate 11 with a shaft attached to the frame side of the frame 2 and the right joint 4 on the right side of the door 3. The frame and the door side support plate 21 with a bearing attached to the door side of the joint 5.6 in the horizontal direction of the top and bottom of the door are used in combination. FIG. 2 is an exploded perspective view of the upper hinge, and the difference from the lower hinge is that the bending direction of the support plate body 12 of the frame side support plate and the support plate body 22 of the door side support plate is different from that of the shaft 14. The same parts were used for the rest, with or without the thrust washer 20 between the cylindrical bearing 32 and the cylindrical bearing 32. Install the lower hinge with the thrust washer in the opposite direction. Since the movement and adjustment procedures are the same, detailed description is omitted.

FIG. 3 (ABC) is a cross-sectional view of the hinge integrated with a combination of the frame-side support plate 11 with shaft, the door-side support plate 21 with bearing, and both from the state of FIG. FIG. 3A shows a frame side support plate that fixes the shaft 14 to the support plate main body 12 and the hole 13 (see FIG. 2) at the front end of the main body, and provides the support plate main body with a long hole 17 and a mounting hole 18 that are also used for position adjustment. . FIG. 3B shows a door-side support plate that is fixed by fitting the skirt portion 28 of the bearing mantle 24 into the support plate main body 22 and the hole 23 at the tip of the main body, and engraves screws 26 on the inner surface of the outer mantle body 25 of the bearing mantle. than the shaft diameter which penetrates over the inner surface providing a wide incision 27.

In the state of FIG. 4 (B), when the cylindrical bearing moves upward, the fitting between the shaft and the cylindrical bearing advances and the cut is closed, so that the door does not come off the frame. The upper hinge that only receives a radial load due to the prevention of door collapse and rotation corresponds to this state. In the state shown in FIG. 4C, the cylindrical bearing moves upward so that the tip of the screw 33 and the top end of the screw 26 of the outer shell body 25 are flush with each other. The hinge stops moving in contact.

When considering FIG. 4 (ABC) in the reverse direction, the lower hinge 8 is obtained. The lower hinge is mainly subjected to the weight of the door, so the portion corresponding to the gap H in FIG. 5C, the periphery of the base portion 16 of the metal shaft 14 and the tip 35 of the cylindrical bearing 32 of the synthetic resin molded product. This is different from the upper hinge 7 in that a metal thrust washer 20 is inserted into the contact surface (see FIG. 6) to prevent wear of the cylindrical bearing. A negative, positive, or polygonal hole 36 is formed at the rear end of the cylindrical bearing for inserting a tool. When the cylindrical bearing further moves and H expands, the door moves upward and the position can be adjusted.

The position adjustment with respect to the up-down direction of the door side support plate 21A of the lower hinge 8 will be described with reference to FIG. In FIG. 5A, a required number of thin plates 37 are inserted between the lower end surface 9 of the door 3 and the support plate main body 22A, the positions are determined after temporarily fixing with screws 31 using the long holes 29, and the mounting holes 30 and screws. Secure with the final tightening. FIG. 5B shows that after the hinge is assembled, the door is hung on the frame 2 and the cylindrical bearing 32 is rotated with a tool (not shown) such as a screwdriver to confirm contact with the washer 20 fitted on the shaft 14. Then, the necessary distance is moved and adjusted in the necessary direction (see FIG. 6.7). The cap 10 is put on the outer surface of the bearing jacket 24 of the door side support plate and used for dust prevention and safety measures. It is not necessary to insert the thin plate into the upper hinge 7, and the cylindrical bearing 32 may be adjusted so that the shaft does not come off the notch 27.

FIG. 6 is an explanatory view of the position adjustment of the lower hinge 8 in the left-right direction of the frame side support plate 11A. A necessary number of thin plates 38 are inserted between the frame 2 and the support plate main body 12A and adjusted in the direction of the arrow. Is temporarily fixed with a screw 19. FIG. 7 is an explanatory diagram of position adjustment of the lower hinge with respect to the front-rear direction of the frame-side support plate. After temporarily fixing in FIG. 6, the position of the frame-side support plate is adjusted in the required direction of the arrow using the long holes. The mounting hole 18 is fixed by tightening with a screw.

FIG. 8 is an installation procedure diagram in the case where the same hinge as that used for the right suspender in the opening / closing device 1 is used for the left suspender. In order to attach the hinge of the present invention to the door 3, the opening direction is reversed (unusual) depending on which of the left and right hinges the left and right hinges are on. A frame-side support plate with a shaft of a hinge on each of the upper and lower sides for the right suspender shown in FIG. A-2 and door side support plate with bearing B-1. When B-2 is used for the left hanging base, the vertical hinge is moved along the diagonal line of the door indicated by the arrow, and the frame-side support plate with axis A-1. A-2 and door side support plate with bearing B-1. The purpose can be achieved by reversely arranging B-2.

That is, the combination of the lower hinge B-2 / A-2 that supports the dead weight of the door is moved along the diagonal line to become the upper hinge A-2 / B-2, and the upper hinge A-1 / that supports the door and guides the rotation. The combination of B-1 may be moved along the diagonal line to form the lower hinge B-1 / A-1. At this time, the thrust washer used in the combination of B-2 / A-2 may be changed to the combination of B-1 / A-1. The procedure for adjusting the position in the three directions is the same as the target hinge is replaced. According to the above procedure, the pivot hinge of the present invention can be applied to a door whose opening and closing direction is reversed only by changing two mounting positions.
