DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat handle device used for a rotary door and the like.

[0002]

2. Description of the Related Art In general, a flat handle device is an actual open flat type.
As disclosed in Japanese Unexamined Patent Publication No. 29670/1992, it is composed of a casing attached to a door and a handle attached to this casing. The casing includes a flat plate part having a rectangular plate shape elongated vertically, and a protruding part formed along the longitudinal direction on the back surface of the flat part, and a front part of the flat part corresponding to the protruding part is provided. An accommodating recess extending therefrom to a protruding portion is formed along the longitudinal direction of the flat plate portion. The casing is attached such that the front surface of the valve closing portion is substantially flush with the front surface of the door.

On the other hand, the handle has a vertically long rod-like or plate-like shape, and its upper end is rotatably supported by the upper end of the accommodation recess. It is housed in the housing recess so as to be on the same plane. On the other hand, at the time of use, it is rotated by a predetermined angle around the upper end, for example, about 30 °, and the lower end protrudes outside from the accommodation recess. The door is opened by gripping the protruding lower end and pulling it toward the front.

[0004] If the handle is formed in a simple rod or plate shape, the handle is inclined by a predetermined rotation angle with respect to the vertical direction when the lower end of the handle protrudes from the accommodation recess. Therefore, the longitudinal direction of the handle is not orthogonal to the direction in which the handle is pulled (horizontal direction). Therefore, it is difficult to pull the handle.

Therefore, in the conventional handle device,
A protrusion is formed on the back surface of the lower end of the handle, and a flat surface portion is formed on the back surface side of the protrusion so as to slope downward from the front side toward the back side. When the handle is pivotally opened by a predetermined angle, the handle is substantially perpendicular to the horizontal direction. Therefore,
By grasping the handle by putting a finger on the flat part, the handle can be reliably pulled toward the user.

[0006]

In the above-structured flat handle device, the length of the flat portion (length in the vertical direction) must be increased in order to more reliably hold the handle. Is good. However, when the length of the flat portion is increased, the height of the projection (the height from the front side to the back side) is correspondingly increased. For this reason, the depth of the accommodation recess for accommodating the handle must be increased. As a result, there is a problem that the dimension from the front surface of the flat plate portion to the tip end surface of the protruding portion increases, and the casing becomes larger. When the casing becomes large, there is an inconvenience that the handle device cannot be attached to the thin door.

Of course, such a problem does not occur if the height of the projection is reduced by shortening the length of the flat portion. However, if the length of the flat portion is shortened, the handle can be securely gripped. And it becomes difficult to open the door.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has as its object to provide a flat handle device which can surely open a door and can be attached to a thin door. I do.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a casing having an elongated accommodating recess, and one end of each of the accommodating recesses of the casing is rotatably supported. A pair of handles that can rotate within a predetermined angle range from a storage position where the entirety is stored in the storage recess to an open position where the other end protrudes outside;
An urging means for urging the pair of handles to rotate from the storage position to the open position, and one end rotatably connected to each of the other ends of the pair of handles so that the pair of handles are housed. When located at the position, the gripping portion accommodated in the accommodation concave portion with the longitudinal direction directed in a direction substantially parallel to the accommodation concave portion, provided between the casing and the gripping portion, the gripping portion A locking mechanism for releasably locking in the housing recess, wherein the casing, the pair of handles and the gripping portion are arranged so that when the pair of handles are rotated, the gripping portions move substantially in parallel. Constitute a substantially parallel link mechanism.

[0010]

[Operation] It is assumed that a pair of handles are located at the storage position. In this state, the grip portion is substantially parallel to the housing recess. Therefore, it is not necessary to increase the depth of the accommodation recess. When the locked state of the grip portion by the locking mechanism is released, the pair of handles are rotated to the open position by the biasing means, and the grip portion moves from the housing recess to the outside. At this time, since the casing, the pair of handles, and the gripping part constitute a substantially parallel link mechanism, the gripping part moves in parallel while substantially maintaining the attitude of being housed in the housing recess. That is, a state substantially parallel to the housing recess is maintained. Therefore, the longitudinal direction of the grip portion is substantially orthogonal to the pulling direction.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. 1 and 2 show a flat handle device A according to an embodiment of the present invention.
FIG. 1A is a longitudinal sectional view showing a state in which a pair of handles are turned to a storage position, FIG. 1B is a longitudinal sectional view showing a state in which a pair of handles are turned to an operation position, and FIG. It is a top view of A. As shown in these figures,
The flat handle device A includes a casing 1, a pair of handles 2, 3, a grip portion 4, and a locking mechanism 5 as main components.

The casing 1 has a flat plate portion 1a and a protruding portion 1b.
And The flat plate portion 1a has a long and narrow rectangular flat plate shape, and has screw insertion holes 1c, 1c at both ends.
Are formed respectively. The protruding portion 1b is formed on the back surface of the flat plate portion 1a along the longitudinal direction. In the flat plate portion 1a and the protruding portion 1b, an accommodation recess 1d extending from the front surface of the flat plate portion 1a to the protruding portion 1b is formed along the longitudinal direction of the flat plate portion 1a.

The casing 1 constructed as described above is housed in a mounting recess 20a formed in the door 20, and is attached to the door 20 by screws (not shown) inserted into the screw insertion holes 1c. In this case, the casing 1 is attached such that the front surface of the flat plate portion 1a is located on the same flat plate as the front surface of the door 20.

In this embodiment, since the casing 1 is attached with its longitudinal direction oriented in the vertical direction, one end is hereinafter referred to as an upper end and the other end is referred to as a lower end for convenience of explanation. Called. Of course, casing 1
May be attached with the longitudinal direction facing left and right.

The housing recess 1d has a shaft 6 having its axis oriented in a direction orthogonal to the longitudinal direction of the housing recess 1d.
7 are provided. One shaft 6 is arranged on the front side of the upper end of the housing recess 1d. The other shaft 7 is disposed slightly closer to the lower end side than the shaft 6 and on the back side.

The upper ends of the handles 2 and 3 are connected to the shafts 6 and 7 respectively.
And is rotatably supported by the casing 1 via the. As will be described later, the handles 2 and 3 are configured to rotate in conjunction with each other, and are rotatable within a predetermined range from an accommodation position accommodated in the accommodation recess 1d to an open position. From the storage position to the open position, the handle 2 is rotated by a spring (biasing means) 10 for biasing the handle 2 in the direction of arrow A.

The storage position is regulated by a locking mechanism 5 described later. In the housing position, one handle 2 is housed so that its front surface is substantially flush with the front surface of the flat plate portion 1a, and the other handle 3 is entirely housed in the housing recess 1d. At this time, handle 2 and handle 3
Means that most parts except the former upper end part and the latter lower end part overlap.

As shown in FIG. 1A, there is a slight gap between the handle 3 and the bottom surface of the accommodation recess 1d at the accommodation position. It is further rotatable, but when the handles 2, 3 are free, they are returned to the storage position by the spring 10.

On the other hand, the open position is regulated by the contact surface 3a formed on the upper end of the handle 3 abutting against the engagement surface 1e formed on the bottom surface of the housing recess 1d.
In this open position, the lower ends of the handles 2 and 3 project outside from the accommodation recess 1d. The open position can also be regulated by forming a protrusion 2a on the handle 2 and arranging the protrusion 2a so as to abut on the handle 3 when the handles 2 and 3 are turned to the open position. It is.

At the lower ends of the handles 2 and 3, shafts 6 and
Shafts 8, 9 parallel to 7 are provided. The upper end of the gripper 4 is rotatably connected to the handles 2 and 3 via the shafts 8 and 9. The grip portion 4 is connected to the handles 2 and 3 with its longitudinal direction facing up and down. When the handles 2 and 3 are turned to the storage positions, the front surfaces thereof are housed in the housing recesses 1d so as to be flush with the front surface of the flat plate portion 1a.

Here, the distance between the axes 6, 7 and the distance between the axes 8, 9 are set to be the same, and the distance between the axes 6, 8 and the distance between the axes 7, 9 are the same. Is set. Therefore, the casing 1, the handles 2, 3 and the gripper 4
Constitute a parallel link mechanism. Therefore, handle 2,
3 rotate in synchronism with each other by the same angle and are always parallel. In addition, the posture of the grip portion 4 is always constant irrespective of the turning position of the handles 2 and 3, and the longitudinal direction thereof is directed in the up-down direction.

The locking mechanism 5 is for keeping the handles 2, 3 and the gripping portion 4 in the storage position when not in use. As shown in FIG. 3, a locking member 5A and a pressing member 5B are provided. And

The locking member 5A has a flat plate shape, a locking portion 5a is formed at the upper end, and inclined surfaces 5a are formed on both sides.
b is formed, and a spring portion 5c is formed at the lower end.
A long hole 5d that is long in the vertical direction is formed at the center. The locking member 5A is provided in a through hole 1f penetrating both lower end portions of the flat plate portion 1a and the protruding portion 1b so as to be movable in the vertical direction and not to move forward. Movement is blocked. Moreover, the locking portion 5a of the locking member 5A is
d, the engaging portions 5a are fitted into engaging concave portions 4a formed on the lower end surface of the grip portion 4, so that the handles 2, 3 and the grip portion 4 are located at the storage positions. ing.

On the other hand, the pressing member 5B has a pressing portion 5e in the form of a flat plate, and this pressing portion 5e is inserted into the through hole 1f so as to be movable in the front-rear direction and immovable in the vertical direction. . An inclined surface 5f (only one inclined surface 5f is shown) is formed on both sides of the pressing portion 5e. This slope 5
f is in contact with the inclined surface 5b of the locking member 5A.
Therefore, when the pressing member 5B is pressed, the locking member 5A moves downward against the spring portion 5c, and the engagement between the locking portion 5a and the engagement recess 4a is released. In the center of the back surface of the pressing portion 5e, a projection 5g is formed to penetrate the elongated hole 5d so as to be movable in the vertical direction. Slot 5 of this projection 5g
d on both sides of the tip protruding therefrom.
h is formed, and this locking projection 5h is formed by a locking member 5A.
The pressing member 5B is prevented from falling out of the through-hole 1f to the near side (the right side in FIG. 1).

In the above-structured flat handle device A,
Now, it is assumed that the handles 2, 3 and the gripper 5 are located at the storage position. In this state, the pressing member 5B
When the is pressed, the locking member 5A moves downward against the urging force of the spring portion 5c, and the engagement between the locking portion 5a and the engagement recess 4a is released. Then, the handles 2, 3 and the gripper 4 are opened and rotated in the direction of arrow A by the spring 10, and stop at the open position. Thereafter, the door 20 can be opened by grasping the grasping portion 4 and pulling it toward the user. At this time,
The longitudinal direction of the grip portion 4 is oriented in the up-down direction, and is orthogonal to the pulling direction. Therefore, the door 20 can be easily opened. In addition, since the handles 2 and 3 are connected to the upper end of the gripper 4, the lower end of the gripper 4 is open. Therefore, it is easy to hold the holding portion 4.

When the device A is not used, the handles 2, 3 and the gripper 4 located in the open position are rotated in the direction of arrow B against the urging force of the spring 10. When the gripper 4 approaches the accommodation position, the lower end of the gripper 4 hits the inclined surface of the locking portion 5a, and pushes down the locking member 5A against the urging force of the spring portion 5c. Then, when the handles 2, 3 and the grip portion 4 reach the storage position, the locking member 5A moves upward by the urging force of the spring portion 5c, and the locking portion 5a fits into the engagement recess 4a. As a result, the handles 2, 3 and the gripper 4 are held at the storage position. At the accommodation position, the grip portion 4 has its longitudinal direction oriented in the vertical direction, that is, the same direction as the longitudinal direction of the accommodation recess 1d. Therefore, even if the grip portion 4 is lengthened, the depth of the accommodation recess 1d needs to be deep. There is no. Therefore, the casing 1 can be reduced in size.

In the flat handle device A, the square formed by the shafts 6, 7, 8, 9 is rectangular at the open position, and the distance between the handles 2, 3 is the largest. In the storage position, the shaft 6,
The square formed by 7, 8, 9 becomes a parallelogram, and the distance between the handles 2, 3 is reduced. Also in this regard, the depth of the housing recess 1d can be reduced.

Next, another embodiment of the present invention will be described. In the following embodiment, only the configuration different from the above embodiment will be described.

The flat handle device B shown in FIG.
The interval between the shafts 7 and 9 is slightly larger than the interval between the shafts 8 and 9, and the interval between the shafts 6 and 8 is slightly larger than the interval between the shafts 7 and 9. In this case, while the longitudinal direction of the gripper 6 is oriented vertically in the storage position, the lower end of the gripper 4 is slightly inclined with respect to the vertical direction in the open position such that the lower end of the gripper 4 approaches the casing 1 from the upper end. . However, the amount is small, and there is no inconvenience in gripping the grip portion 4.

The flat handle device C shown in FIG. 5 is different from the device B in that the distance between the shafts 6 and 7 is slightly smaller than the distance between the shafts 8 and 9 and the distance between the shafts 6 and 8 is Are slightly smaller than the intervals. In this case, when the longitudinal direction of the gripper 4 is in the open position, the lower end of the gripper is slightly inclined with respect to the vertical direction so as to be farther from the casing 1 than the upper end.

Here, the flat handle device A,
In B and C, a pair of handles 2 and 3 are connected only to one end of the grip portion 4, and the grip portion 4 is in a so-called cantilever state. This is for the following reason.

That is, FIG. 6 shows a flat handle D having both holding portions 4 for comparison with the flat handle devices A, B and C. In this flat handle device D, a handle is provided. One end of the handle 2 is rotatably supported by the upper end of the housing recess 1d, and one end of the handle 3 is rotatably supported by the center of the housing recess 1d. Both ends of the gripper 4 are rotatably connected to the other ends of the handles 2 and 3, respectively. As a result, the grip portion 4 is supported by the handles 2 and 3 in a double-supported state. When both ends of the gripper 4 are connected to the handles 2, 3, respectively, the space surrounded by the handles 2, 3 and the gripper 4 is narrow if the rotation angle of the handles 2, 3 toward the open position is small. Therefore, a hand cannot be put in the space, and the grip portion 4 cannot be gripped. Therefore, the turning angles of the handles 2 and 3 are increased, and as shown in FIG.
It needs to be turned 0 °. However, handles 2, 3
When the rotation angle of the spring 10 is increased, the urging force of the spring 10 becomes extremely large when the handles 2 and 3 are rotated to the storage positions. For this reason, when the locking state of the grip portion 4 by the locking mechanism 5 is released, the handles 2 and 3 and the grip portion 4 vigorously rotate from the housing recess 1d. Moreover, the rotation angle is large. For this reason, there is a possibility that the hands 2, 3 or the gripper 4 may injure the hand.

In this regard, the flat handle device A of the present invention,
In B and C, since the handles 2 and 3 are connected only to one end of the gripper 4, the other end of the gripper 4 is opened. Therefore, even if the rotation angles of the handles 2 and 3 from the storage position to the open position are small, the grip portion 4 can be sufficiently gripped. By reducing the rotation angles of the handles 2 and 3, the urging force of the spring 10 when the handles 2 and 3 are rotated to the storage position can be reduced. Therefore, the risk of injury to the hand by the handles 2, 3 or the gripper 4 can be greatly reduced.

[0034]

As described above, according to the flat handle device of the present invention, since the casing, the two handles and the grip portion constitute a substantially parallel link mechanism, the longitudinal direction of the grip portion is accommodated. In both the open position and the open position, it can be made substantially parallel to the longitudinal direction of the housing recess, so that the door opening operation can be reliably performed, and the casing is downsized and attached to a thin door. be able to. In addition, the grip portion can be easily gripped only by rotating the pair of handles by a small angle, and the effect that the risk of injury to the hand by the handle or the grip portion can be greatly reduced can be obtained. Can be
