Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a blade hinge mounted as an opening / closing support member between a fixed body of a building or furniture and a door installed in the fixed body.

[Prior Art] Conventionally, in this type of blade hinge, a blade plate having a shaft tube formed on one side between a fixed main body such as a frame body and the door, and both shaft tubes in the axial direction of the door. It is fixed in a state of being communicated with each other, and a shaft pin is inserted between each shaft tube.

Generally, when installing a door on the fixed body, it is possible to set the shaft pin on the vane plate of either the fixed body or the door, align the shaft pin with the shaft tube and fit it while moving the door. It is being appreciated.

[Problems to be solved by the device]

By the way, in the above-mentioned case, it is necessary to position the door in a state in which the door is axially displaced by at least the length in which the shaft pin projects from the shaft tube in which the shaft pin is set.

In the frame structure in which the surface positions of the fixed main body and the side surface of the door substantially match with the door installed at the predetermined position, the axial movement of the door regulates the fixed main body at a rotation position of approximately 90 ° with respect to the fixed main body. Since it is not received, it is possible to move more than the protruding amount of the shaft pin and it is easy to fit, but in a frame structure in which the surface position of the fixed main body protrudes from the surface position of the door, such as a decorative frame, Even at a rotating position of about 90 °, the fixed body is still restricted, and only a moving distance within the axial clearance gap between the fixed body and the door, which is usually set to several mm, can be obtained. For this reason, in the case of a frame structure such as a decorative frame, with the shaft pin removed in advance, the doors are moved within the allowance gap dimension to align the shaft tubes, and after the alignment, the shaft pin must be inserted. I don't get. However, since the alignment of the shaft tubes is a simple butt alignment that does not have an engaging shape, it is easy to misalign and the mate of extremely small areas can also be aligned, so smooth insertion of the shaft pin can be obtained. It is extremely difficult to match such a case, and it becomes more difficult when the outer shape and the weight of the door are large. Even in the frame structure in which the surface positions are substantially the same, the same problem occurs when some structure is fixed near the frame and the rotation of the door is hindered.

Therefore, an object of the present invention is to provide a blade hinge that can easily attach or detach the door within a moving distance within the axial clearance gap of the door with respect to the fixed body regardless of the frame structure.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the invention is directed to a fixed main body such as a frame body, a pair of blade plates fixed to a door rotatably installed on the fixed main body, and one side of these blade plates. In a blade hinge consisting of a shaft tube formed so as to be able to communicate in the axial direction and a shaft pin inserted between the shaft tubes, an axial margin of the door with respect to the fixed body is provided at the opposite end of each shaft tube. The structure is such that an engaging portion capable of temporarily suspending the door is formed at a moving distance within the gap size.

[Action]

According to this invention, the axial tubes are aligned with each other by the movement distance of the door within the margin size, and the axial tubes are engaged with each other by the engaging portions formed at the opposite ends. Due to this engagement, the door is temporarily suspended, and the shaft pin is inserted between the shaft tubes, whereby a predetermined mounting is performed.

〔Example〕

1 to 6 show an embodiment of the present invention. Wall surface W
A frame 2 is installed in the frame 2, and a door 6 having a knob 4 is rotatably attached to the frame 2 via a plurality of blade hinges 8. A clearance gap d is provided between the frame body 2 and the upper end of the door 6.
Is set.

The blade hinge 8 is, as shown in FIG. 2, a pair of blade plates 10 and 12 fixed to corresponding positions of the frame 2 and the door 6, respectively.
And the shaft tubes 14 and 16 formed to be able to communicate in the axial direction on the one side 10a and 12a of the vane plates 10 and 12, and the shaft pin 18 inserted between these shaft tubes 14 and 16. There is. In addition, the opposite ends 14a, 1 of the shaft tubes 14, 16
Between the 6a, a collar member 20 made of synthetic resin or the like having good slidability or lubricity is appropriately set so that smoothness at the time of turning the door 6 can be obtained, or rubbing noise can be suppressed. It has become so.

A plurality of countersink holes 22 having countersinks on the front surface side are formed in each of the vane plates 10 and 12, and are fixed by set screws 24.

The shaft tubes 14 and 16 are formed relatively at the upper and lower half positions in the axial direction of the blade plates 8 and 10, and for example, the extension pieces of the blade plates 8 and 10 are bent or separated. The formed hollow member can be fixedly formed by means such as welding. A sealing member 28 having a head shape substantially similar to the head 26 of the shaft pin 18 is fitted to the lower end of the shaft tube 14 on the side of the frame body 2 from the viewpoint of obtaining external symmetry. At the opposite end 14a of the shaft tube 14, a small-diameter convex portion 30 as an engaging portion for temporarily suspending the door 6 is formed,
On the other hand, corresponding to this, the opposite end 16a of the shaft tube 16 on the door 6 side
A concave portion 32 as an engaging portion that fits into the convex portion 30 is formed in the. Of course, the convex portion 30 and the concave portion 32 may be formed in the opposite manner.

The dimension of the convex portion 30 as the engaging portion is set to the dimension d ₁ within the allowance gap d between the frame body 2 and the upper end of the door 6, and the dimension of the corresponding concave portion 32 is equal to d ₁ . It is set higher than that.

When installing the door 6, first, as shown in FIG. 3, the door 6 is moved by a moving distance within the allowance gap d so that each axial pipe 14, 1
6 are aligned so that their engaging portions face each other. Then, by moving the door 6, as shown in FIG.
4, 16 are engaged with each other. Engagement is convex 30 and concave 32
Due to the fitting structure, the work becomes easy. Due to this engagement, the door 6 can be temporarily suspended, and the holding force of the operator becomes unnecessary. Further, the shaft tubes 14 and 16 are communicated with each other in the axial direction, and after the temporary suspension, the shaft pin 18 is inserted between the shaft tubes 14 and 16 to complete the attachment.

In addition, when the collar member 20 is installed, as shown in FIG. 5, the protrusion 30 further has a thickness d of the collar member 20.
It is set to the size with ₂ added.

Therefore, regardless of the frame structure, the door 6 can be removed with a slight movement adjustment within the clearance d.
The workability can be improved, and the same range of functions can be obtained even under the condition that the rotation of the door 6 is restricted, so that the range of application can be expanded.

In this example, a specific concavo-convex structure is illustrated as the engaging portion, but the engaging portion is not limited to this, and can be appropriately determined within a range that enables engagement and has temporary suspension strength.

Further, in this example, below the head portion 26 of the shaft pin 18,
A step portion 34 having a small diameter is formed to separate the head portion 26 and the upper end of the shaft tube 16 from each other. In the conventional blade hinge, since the lower surface of the head of the shaft pin and the upper end of the shaft tube are in close contact with each other, it is not easy to remove the shaft pin when removing the door. That is, when the shaft pin is pulled out, it is usual to push a member such as a driver 36 having a sharp tip into the tight contact portion and knead it up. It was not easy, and the hinge member was sometimes damaged by forced pushing.

Therefore, by adopting a structure in which the step portion 34 is formed,
Such an inconvenience can be avoided, and the driver can easily perform the extraction operation using familiar members. The shape or size of the step portion 34 can be appropriately selected within a range that does not impair the outer appearance of the hinge.

[Effect of device]

According to this invention, the door can be temporarily suspended by adjusting the movement of the door in the axial clearance gap with respect to the fixed body, so that the door can be attached or detached regardless of the frame structure, thus improving workability. Can be improved. Further, the same range of functions can be obtained even under the condition that the rotation of the door is restricted, so that the range of application can be expanded.
