Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle device. More specifically, the present invention relates to a movable handle device that can operate a latch lock provided on a door.

[0002]

2. Description of the Related Art As a conventional handle device for this type of door, for example, the one disclosed in Japanese Utility Model Laid-Open No. 27069/1992 can be cited. The handle device has one end, which is a lower end or an upper end of a vertically elongated handle, pivotally supported on a lower or upper seat attached to a surface of a door, and is the upper end or the lower end of the handle. The end is exposed to the upper or lower seat and engaged with an operating piece rotatably provided inside the seat, and the handle is perpendicular to the door surface and the door opening direction. It is provided so as to rotate the above-mentioned operating piece by pushing or pulling it, and the tip end of the operating piece is engaged with the latch operating member of the door lock, and the handle is pushed or pulled to retract the latch of the door lock. The door is configured to be opened as well as to be opened.

[0003]

However, according to the above-mentioned conventional device, since the vertically elongated handle has only one end pivotally supported and the other end swingable back and forth, the handle is disposed near the pivot. Depending on the moment, there is a difference in the operating force required to push or pull the handle between when the handle is grasped and when the handle is grasped at a position away from the pivot, and the handle operation may not be performed smoothly.

The door handle device according to the present invention enables a vertically long handle to be smoothly operated with almost the same operating force regardless of the position of the handle.

[0005]

In order to achieve the above object, the door handle device of the present invention has a vertically long handle on a pedestal fixed to the front surface of the door via a first arm and a second arm. Movably supported; the base end and the tip of the first arm are pivotally attached to the upper ends of the pedestal and the handle at the first and second pivots, respectively; the tip and the base end of the second arm are the third pivot and Pivotally attached to the lower end of the handle and the pedestal at a fourth pivot; first, second, third and fourth
Four links connecting the pivots in sequence form a parallelogrammatic link mechanism; the link mechanism is provided with a return spring for returning the link mechanism to a normal position; and
By pushing and pulling the handle, the latch of the latch lock provided on the door is retracted or the retracting of the latch is allowed to open to open the door. Therefore, the first arm or the first arm of the link mechanism is connected to the latch of the latch lock via the linking member. The construction condition is that two arms are linked.

[0006]

When the door 10 is in the closed state (see FIG. 1), the handle 2 which forms one link of the parallelogram linkage mechanism 6.
Is manually pulled in the direction of arrow A against the return spring 8, the handle 2 is displaced in parallel with the swing of the first and second arms 3 and 4 by using the base 1 as a fixed link in the link mechanism 6. To do.

At this time, the linking member 9 swings in the direction of arrow B as the first arm 3 swings, and the tip of the latch (not shown) of the latch lock 20 linked to the linking member 9 is locked. The door 10 can be opened in the direction of arrow C by continuing to pull the handle 2 as it is.

On the contrary, when the door 10 is closed and the hand is released from the handle 2, each displaced member returns to its original normal position by the urging force of the return spring.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings. When the handle device of the present invention is provided on the door 10 as an entrance / exit, it is usually attached to both the outside surface and the inside surface of the door, but when it is provided to the door of the container, it is sufficient to attach it only to the outer surface thereof. .

In the illustrated embodiment, handle devices are attached to both the inside and outside surfaces of the door 10. The pedestals 1 and 1 in the pair of inner and outer handle devices may be fixed to both sides of the door 10 by attaching screws 91 including female and male screws.

Here, the outdoor side of the door 10 (right side in FIG. 1)
The handle device mounted on the surface will be described as a representative.

Although the pedestal 1 in the illustrated example is provided as a pair in the upper and lower sides, the upper and lower pedestals may be integrated.
The pedestal 1 movably supports a vertically long handle 2 at the upper and lower ends via a first arm 3 and a second arm 4.

The upper and lower mounting portions 21 and 21 of the handle 2 and the facing portions 11 and 11 of the pedestal 1 are provided with hollow portions for mounting the arms 3 and 4, the return spring 8 and a linking member 9 which will be described later. Each is provided.

The base end and the tip end of the first arm 3 are pivotally attached to the upper ends of the pedestal 1 and the handle 2 above via the first pivot 51 and the second pivot 52, respectively.
The distal end and the proximal end of the arm 4 are pivotally attached to the lower end portion of the handle 2 and the lower pedestal 1 via a third pivot shaft 53 and a fourth pivot shaft 54, respectively.

Each pivot is preferably mounted horizontally and parallel to the surface of the door 10. Reference numerals 12 and 22 denote the above-mentioned pivot 5
1 to 54 and the like are attached to the hollow portion of the pedestal 1 and the hollow portion of the handle 2 with fixing screws 92 and the like. Reference numeral 13 is a lid portion forming a part of the attachment piece 12.

First, second, third and fourth pivots 51-54
The four links connecting in sequence form a parallelogram-shaped link mechanism 6.

In other words, the parallelogrammatic link mechanism 6 shown schematically and in principle by the one-dot chain line in FIG.
The pedestal 1 fixed to the first arm 3, the first arm 3 movable with respect to the door 10, the handle 2 and the second arm 4 are connected to both ends by pivots 51, 52, 5
3 and 54 are sequentially connected.

The movement range of the handle 2 which can be moved in parallel with respect to the fixed base 1 is limited by the movement limiting means 7 provided between the two.

The movement limiting means 7 in the illustrated example includes first and second movement limiting means 7.
The arms 3 and 4 and the mounting pieces 12 and 12 fixed in the upper and lower pedestals 1 and 1 are provided as a pair, and the means 7 is a fixed pin 71 and a long hole into which the pin 71 is fitted. 72
The range of parallel movement of the handle 2 is limited by limiting the swing range of the first and second arms 3 and 4.

Reference numeral 8 is the upper and lower pedestals 1, 1 and the first and second pedestals.
The link mechanism 6 is a return spring such as a torsion spring that is vertically suspended between the arms 3 and 4, and the link mechanism 6 is returned by the return spring to the normal position in the non-operating state (direction opposite to arrow A). ).

In the embodiment, each torsion spring 8 is wound around the pipe body of the first pivot shaft 51 (or the fourth pivot shaft 54), and one end thereof is located in the first arm 3 (or the second arm 4). It is locked to a pin 71 fixed to the handle 2, and thus applies a required biasing force to the handle 2 via both arms 3 and 4 of the link mechanism 6.

A working piece forming a part of the linking member 9 is fixed to the first arm 3 or the second arm 4.
The linking member 9 is linked to a latch (not shown) of a latch lock 20 dug into the door 10, and the push-pull operation of the handle 2 moves the latch backward or backward. Allow it to open the door.

The above-mentioned latch may be of an oscillating type or an inversion type, but the latter inversion type is preferable from the viewpoint of reducing the displacement amount.

The structure of the handle device fixed to the outside of the door 10 (right side in FIG. 1) is as described above.

The handle device which can be provided symmetrically with the door device, that is, the handle device which is mounted on the surface of the door 10 on the indoor side (left side in FIG. 1) is different from the above-mentioned one mainly in the following structure. Since other parts are almost the same, further detailed description will be omitted.

When the door 10 is opened, it is convenient to push the handle 2 in the direction of the arrow D to open the door, so that the return spring (8) is biased away from the base 1.

Further, when the handle 2 is operated, the handle 2 is pushed into the pedestal 1 from the normal position, so a sufficient clearance between the two is required between the two. In FIG. 1, arrow E indicates the swinging direction of the operating piece that forms a part of the linking member 9 on the indoor side during operation.

[0028]

In the door handle device of the present invention described above, the vertically long handle is configured to form a part of a parallelogram-shaped link mechanism, and therefore, when the handle is pushed and pulled, Since the handle is displaced in parallel, no matter which position is held in the vertical direction, the handle can be smoothly operated with substantially the same operating force.
