Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge device.

[0002]

2. Description of the Related Art As a hinge device used to hold a door so that it can be opened and closed within a door frame, there are provided a male member and a female member which are separately provided on the door and the door frame and can be connected to each other. It is well known that the male member is provided with a hinge shaft whose axis is directed up and down, and the other female member is provided with a bearing portion capable of fitting the hinge shaft of the male member. It is.

In the above-mentioned hinge device, a so-called "hinge" which is attached to a rear end surface of a door or an inner surface of a vertical frame of a door frame via a mounting plate parallel to the above is excluded. That is, the male side member and the female side member are mounted at positions corresponding to the upper end and lower end of the door (the one provided with the hinge shaft projecting to one side of the door, Some are provided at the center of the thickness).

[0004]

The female member of the hinge device can easily and quickly perform the operation when the door needs to be attached to or detached from the door frame due to various reasons such as maintenance. In order to do so, it is desired to have a structure that can be easily attached to and detached from the male member, that is, a hinge shaft can be easily fitted and opened.

However, a structure for this purpose is a structure in which a cam mechanism, a crank mechanism, a ratchet mechanism, or the like is combined, and a strong spring is incorporated in some cases, and a security structure for dealing with tampering, theft, and the like is provided. Because of the necessity of adopting such an element, it is very complicated, large, heavy, and expensive, so that there is much room for improvement.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and can be easily and quickly attached to and detached from a male member having a hinge shaft, and can be simplified in structure, reduced in weight, and reduced in cost. It is an object of the present invention to provide a female member of a hinge device capable of achieving the above.

[0007]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the female member of the hinge device according to the present invention, a main body portion provided with a cutout portion capable of horizontally fitting the hinge shaft of the male member, and a shaft slidably provided on the main body portion. A gripping member. The sliding range of the shaft gripping member is between an open position for opening the notch in the main body and a closed position for preventing the hinge shaft fitted in the notch from coming out.

That is, in the main body, the shaft gripping member is opened, the hinge shaft of the male member is laterally fitted into the notch, and the shaft gripping member is set to the closed position in this state.
The hinge shaft can be prevented from coming out of the notch, and the hinge shaft can be easily removed from the notch again by moving the shaft gripping member to the open position from this state.

If the shaft gripping member is configured to be biased by a spring toward the closed position with respect to the notch, there is no need to move from the open position to the closed position, and the hinge shaft is fitted into the notch. In this state, it is possible to prevent the hinge shaft from slipping out and rattling. In this case, if the shaft gripping member has a structure that can be locked and held at the open position with respect to the notch, it leads to an advantage that the operation of fitting the hinge shaft into the notch can be performed easily.

[0010] If the shaft gripping member is configured to swing inward in the radial direction of the notch as it approaches the closed position from the open position with respect to the notch, the shaft gripping member can be swung in a state where the hinge shaft is fitted in the notch. This leads to the advantage that the rattling of the hinge shaft can be prevented. When the shaft gripping member 12 pushes the hinge shaft toward the notch when it is in the closed position with respect to the notch, and holds the hinge shaft together with the notch, the position of the hinge shaft is set accurately and the backlash is improved. It can be surely prevented.

If the shaft gripping member is provided with a cam surface which generates a moving force to the open position upon contact with the hinge shaft, it is not necessary to move the shaft gripping member each time, and the handling is further improved. It becomes convenient. That is, it is assumed that the notch of the main body is empty and the shaft gripping member is stopped at the closed position with respect to the notch. In this state, if the hinge shaft is pushed in the manner of laterally fitting the hinge shaft into the notch, the hinge shaft naturally interferes with the portion of the shaft gripping member that blocks the front of the notch. Become.

Therefore, in the shaft gripping member, the cam surface is formed at a portion receiving the contact, and when receiving the contact force by the hinge shaft, the cam surface is moved to the open position with respect to the shaft gripping member. It is assumed that there is a slope that converts the moving force into the moving force. The main body is provided with a stopper member that can protrude into a movement passage of the shaft gripping member to the open position when the shaft gripping member stops at the closed position with respect to the notch.

That is, by projecting the stopper member into the movement passage, the shaft gripping member cannot be moved from the closed position to the open position, and as a result, the hinge shaft escapes, that is, the female side member and Since the female member and the male member cannot be separated from the male member, the female member and the male member can be protected from mischief or theft. Such a stopper member is positioned so as to be hidden behind the male member when the female member and the male member overlap (when the door is closed). Is preferred.

That is, in such a position,
This is because the stopper member cannot be operated because the male member is in the way and cannot be retracted from the moving passage of the main body in the female member. As a result, the above security effect can be enhanced. By forming the shaft gripping member in a U-shaped cross section sandwiching both side surfaces of the main body, strength can be improved and smoothness in mobility can be obtained.

The main body may be provided with a structure in which the notch can be positioned within the thickness range of the door. As a result, the entire door can be configured to be neat.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. First, the hinge device 1 will be schematically described with reference to FIGS. As shown in FIG. 4, the hinge device 1 is provided at a position corresponding to the upper end of the door 2 (U type), and is provided at a position corresponding to the lower end of the door 2 (L type). It is roughly divided.

Each of these two types is constituted by a combination of a member (d member) attached to the door 2 and a member (f member) attached to the door frame 3. Here, as shown in FIGS. 5 and 6, one of the combination patterns of the d member and the f member is a male member provided with a hinge shaft 5 whose axis is directed vertically. In addition, the other is necessarily a female member provided with a bearing 6 to which the hinge shaft 5 can be fitted.

However, as apparent from FIGS. 5 and 6, whether the d member is a male member or a female member, and the f member is a female member or a male member is not determined. , Without any limitation, U type and L
There is no limitation on how to combine the types. In some cases, the same d member and f member can be used for the U type and the L type.

From the above, the female member of the hinge device 1 according to the present invention is applicable to any of the above-mentioned U-type d members and f members, and L-type d members and f members. Is what is done. FIG. 7 shows a hinge device 1 in which a U-type (upper) f member is a female member and a d member is a male member (ie, the pattern shown in FIG. 5A).
And a hinge device 1 using the L-type (lower) d member as a female member and the f member as a male member (that is, the pattern shown in FIG. 6 (b)). The example attached to the frame 3 is shown.

In this, a female member 10 (first embodiment) according to the present invention is applied as a U-type f member. It is preferable that the male member, which is a mating member of the female member 10, be one in which the hinge shaft 5 is rotatable around its axis. As shown in FIGS. 1 to 3, the female member 10 according to the first embodiment includes a main body 11 and a shaft gripping member 12 movably (slidably) provided with respect to the main body 11. Have. In this shaft gripping member 12, the moving direction with respect to the main body 11 is
When the door 2 is in the closed state with respect to the door frame 3, the direction is parallel to the door surface of the door 2 (hereinafter, this direction is referred to as “left-right direction”).

The main body 11 is formed in a plate shape.
Base plate portion 11 provided with mounting hole 14 for door frame 3 or the like
a, and an extension plate portion 11b extending obliquely forward from the base plate portion 11a. The extension plate portion 11b is provided with a U-shaped notch portion 15 which is open at the front side and allows the hinge shaft 5 of the male member to be laterally fitted.

On the other hand, the shaft gripping member 12 is also formed in a plate shape, and is provided so as to be overlapped on the extension plate portion 11b of the main body portion 11. At the front end of the shaft gripping member 12, a shutter piece 18 that protrudes or retracts across the opening of the cutout 15 as it moves with respect to the main body 11 is provided in a side projection shape. .

In other words, in other words, the range of movement of the shaft gripping member 12 with respect to the main body 11 depends on the position of the hinge shaft 5 in which the shutter piece 18 is fitted in the cutout 15.
Between the closed position (the cutout 15 does not need to be a complete endless hole) and the open position opened so that the hinge shaft 5 can be inserted into and removed from the cutout 15. I have.

Thus, in the female member 10,
The notch 15 of the main body 11 and the shutter piece 18 of the shaft gripping member 12 form a hole for fitting the hinge shaft 5 of the male member.
Is constituted. The shaft gripping member 1
2 is provided with a finger hanging piece 19 so as to rise in a bent shape along the front edge of the shutter piece 18.

A specific structure for allowing the shaft gripping member 12 to move freely with respect to the main body 11 is that a guide groove 23 is formed through the plate surface of the shaft gripping member 12 so that its longitudinal direction is directed to the left and right. And the two support shafts 24 and 25 are spaced apart from each other by a predetermined distance with respect to the guide groove 23.
And the support shafts 24 and 25 are fixed to the main body 11 by screws or press-fitting.

At least one of the support shafts 24 and 25 (both in the illustrated example) is configured to be able to abut the guide groove 23 of the shaft gripping member 12 against the opening edge thereof. , A retaining piece 26 that protrudes in a flange shape is provided. Therefore, the shaft gripping member 12 with respect to the main body 11
Is smoothly performed without rattling, and the shaft gripping member 12 is prevented from being detached from the main body 11.

On one of the support shafts (the support shaft 25 which is closer to the notch 15 in the illustrated example), a spring hook portion 28 is provided which projects beyond the retaining piece 26 in the axial direction. Also,
In order to form a pair with this, the shaft gripping member 12 is provided with a spring hooking pin 29 protruding near an end opposite to the projecting side of the shutter piece 18.
A spring 30 is stretched in a tension state between the support shaft 25 with the above-mentioned spring hook 28 and the spring hook 28.

Therefore, this spring 30 is
A spring force is generated in a direction in which the shaft 9 and the support shaft 25 with the spring hooking portion 28 are brought close to each other, whereby the shaft gripping member 12
The shutter piece 18 is always connected to the cutout 1 of the main body 11.
5, that is, the spring is biased toward the closed position with respect to the notch 15 (the state shown in FIG. 2).

By the way, the guide groove 23 of the shaft gripping member 12
At the end of the groove near the shutter piece 18, a hook-shaped bent portion 33 (see FIG. 2) is provided, and at the opposite end of the groove, an oblique swing guiding portion 34 is provided.
(See FIG. 1). Therefore, the shaft gripping member 1
2 is moved from the closed position to the open position with respect to the notch portion 15, the locking portion 33 is fitted into the support shaft 25 with the spring hooking portion 28 to be in a locked state. The state in which the gripping member 12 is stopped at the open position with respect to the notch 15 (the state shown in FIG. 1) is locked and held.

Therefore, in this situation, the notch 1
There is an advantage that the hinge shaft 5 can be easily taken in and out of the hinge shaft 5 (even one worker can do it). In order to return the shaft gripping member 12 to the original closed position from this state, it is only necessary to push the finger hook 19 lightly so as to push it inward. On the other hand, when the shaft gripping member 12 is moved from the open position with respect to the notch portion 15 to the closed position, when reaching the closed position, the swing guide portion 34 slides on the support shaft 24. As a result, the shaft gripping member 12 swings such that the shutter piece 18 is directed radially inward of the cutout 15. That is, the inner diameter of the notch 15 (the inner diameter of the bearing 6) is reduced accordingly, so that if the hinge shaft 5 is fitted as the bearing 6, the inner diameter of the hinge shaft 5 is reduced. Grasping is strengthened, and it is maintained in a state without rattling.

When the shaft gripping member 12 is in the closed position with respect to the notch 15 in the main body 11 (see FIGS. 2 and 3).
In addition, a stopper member 36 is provided, which can protrude into a movement passage for moving the shaft gripping member 12 to the open position. The stopper member 36 uses a bolt and is screwed to the main body 11 from the lower surface side.

Therefore, by tightening the stopper member 36, it is possible to protrude into the moving passage. As a result, the shaft gripping member 12 cannot be moved from the closed position to the open position. As a result, Thus, the hinge shaft 5 comes out, that is, the male member cannot be separated from the female member 10. As a result, the female member 10 and the male member, and thus the door 2 itself, can be protected from mischief or theft.

The stopper member 36 is connected to the female member 1.
When the door 0 is closed, that is, when the door 0 is closed, the position is hidden behind the male member. Therefore, the stopper member 36 cannot be retracted from the moving passage of the main body 11. Therefore, the above-described security effect can be further enhanced.

In the female member 10 having such a structure,
To assemble the male member, first, the stopper member 36 is loosened and retracted from the movement passage of the shaft gripping member 12,
A finger is hooked on the finger hook 19 of the shaft gripping member 12, and the finger is moved toward the open position. This movement is performed by the guide groove 23.
If it goes to the full length, the locking portion 3 of the guide groove 23 naturally
3 and the support shaft 25 are engaged with each other, whereby the shaft gripping member 12 is engaged.
In the open position is locked and held.

Then, the hinge shaft 5 of the male member is fitted into the notch 15 opened in the main body 11 in a laterally fitting manner. Then, just by lightly pushing the finger-holding piece 19 of the shaft gripping member 12 backward, the engagement between the locking portion 33 of the guide groove 23 and the support shaft 25 is released, and the shaft gripping member 12 exerts the spring force of the spring 30. As a result, the hinge shaft 5 can be fitted to the bearing 6, that is, the male member can be assembled to the female member 10.

In this state, the stopper member 36 may be tightened to prevent the shaft gripping member 12 from being opened relative to the main body 11. When removing the male member from the female member 10, the operation may be performed in a procedure substantially opposite to that described above. FIG. 8 shows a second embodiment of the female member 10 according to the present invention.

The second embodiment differs from the first embodiment in that the shaft gripping member 12 is formed to have a U-shaped cross section so as to sandwich the front and back surfaces of the main body 11. The point is that a cam surface 40 is provided on the front side of the shutter piece 18 of the shaft gripping member 12. The fact that the shaft gripping member 12 has a U-shaped cross section
It is intended to increase strength and facilitate mobility.

The cam surface 40 provided on the shutter piece 18 is in a state where the shaft gripping member 12 is stopped at the closed position with respect to the notch 15 and the notch 15 is empty (the hinge shaft 5 is fitted). When the hinge shaft 5 is pushed into the notch portion 15 when the hinge shaft 5 is pushed into the notch portion 15, a force is applied to move the shaft gripping member 12 to the open position by receiving the contact force with the hinge shaft 5. The direction of the is changed.

Therefore, the cam surface 40 is inclined at about 45 ° with respect to the front-rear direction (the pushing direction of the hinge shaft 5). For this reason, when assembling the male member to the female member 10, there is no need to move the shaft gripping member 12 each time, which makes the handling more convenient.

FIG. 9 shows a third embodiment of the female member 10 according to the present invention.
1 shows an embodiment. In the third embodiment, the shaft gripping member 12 is formed as a single piece, and
In FIG. 3, the locking portion 33 and the swing guide portion 34 are not provided. That is, the structure is simplified as a whole. However, in the shaft gripping member 12,
A cam surface 40 is provided on the shutter piece 18, and an auxiliary finger hook 42 is provided on the side opposite to the shutter piece 18, so that the convenience in use is improved to some extent.

FIG. 10 shows a fourth embodiment of the female member 10 according to the present invention. In the fourth embodiment, the shaft gripping member 12 of the third embodiment (see FIG. 9) is formed in a U-shaped cross section. FIG. 11 shows a fifth embodiment of the female member 10 according to the present invention. In the fifth embodiment, the structure is thoroughly simplified, and the shaft gripping member 12 in which the guide groove 23 is formed is movably stopped with respect to the main body 11 by one support shaft 24. It is just attached. Even such a device sufficiently satisfies the basic principle of the present invention that the attachment / detachment to / from the male member is simple and quick, and can be suitably used in a portion for attaching a relatively lightweight opening / closing body. .

FIG. 12 shows a sixth embodiment of the female member 10 according to the present invention. In the sixth embodiment, in the main body 11, the extension plate 11 extends from the base plate 11a.
The notch 15 is positioned within the thickness range of the door 2 by suppressing the amount of extension of b. In this case, a storage recess 45 for attaching the female member 10 is formed in the upper frame 3a of the door frame 3, and the storage recess 45 is used to move the shaft gripping member 12 and to operate the male member. Are opened downward and forward so as to be able to be attached to and detached from the hinge shaft 5. After assembling the hinge shaft 5, a cover 48 having a notch 47 for escape with respect to the hinge shaft 5 is attached to the upper frame 3a of the door frame 3,
Each opening of the storage recess 45 is closed.

By the way, the present invention is not limited to the above embodiments, and the detailed structure, member shape and the like can be appropriately changed according to the embodiment. Further, the hinge device 1 including the female member 10 according to the present invention.
However, the door 2 to be attached is not limited to the door 2, and can be applied to various kinds of doors, cupboards, and the like.

Further, as a method of swinging the shaft gripping member 12, it is most reliable to form an inclined portion in the guide groove 23, but other methods may be used. It is sufficient that the hinge shaft 5 can be pushed into the notch 15 by the shutter piece 18 and held together with the notch 15 when the shutter piece 18 is brought to the closed position, with the surface on the side of the portion 15 being an inclined surface.

[0045]

As is clear from the above description, the female member of the hinge device according to the present invention has a main body portion provided with a cut-out portion which allows the hinge shaft of the male side member to be horizontally fitted, and this main body. A shaft gripping member movably provided with respect to the portion, the shaft gripping member making an open position for opening a cutout portion of the main body portion and a hinge shaft fitted in the cutout portion unable to escape. It is slidable between the closed position.

Therefore, by simply sliding the shaft gripping member between the open position and the closed position with respect to the main body, the attachment / detachment of the hinge shaft to / from the notch portion, that is, the assembling with the male member having the hinge shaft, and It is very easy and quick to remove. Moreover, only the main body and the shaft gripping member are provided, so that structural simplicity, weight reduction, cost reduction, and the like can be drastically achieved as compared with conventional ones.

The structure in which the shaft gripping member is biased to the closed position by a spring has the advantages that the moving operation toward the closed position is not required, and the escape after the hinge shaft is fitted and the rattling can be prevented. is there. At this time, if the shaft gripping member has a structure that can be locked and held at the open position, it leads to advantages such as easy attachment / detachment of the hinge shaft (can be performed by one worker).

If the shaft gripping member is configured to swing inward in the notch portion at the closed position, it is possible to prevent rattling of the hinge shaft fitted in the notch portion. When the shaft gripping member has a structure in which the hinge shaft is pushed toward the notch when the closed position with respect to the notch is attained, and the hinge shaft is sandwiched together with the notch, the position of the hinge shaft is set accurately and This leads to the advantage that rattling can be more reliably prevented.

If the shaft gripping member is provided with a cam surface which can be moved to the open position only by pushing the hinge shaft when it is in the closed position, the operation for moving to the open position can be obviated. It becomes convenient. If a stopper member is provided for the main body so that the shaft gripping member cannot be moved from the open position to the closed position, the female member, the male member, and eventually the door can be protected from mischief or theft. Become.

By setting the stopper member so as to be inoperable when the female member and the male member overlap each other, the above-mentioned crime prevention effect can be further enhanced. If the shaft gripping member has a U-shaped cross section, the strength can be improved and the mobility can be smoothed.
