Description

[Detailed Description of the Invention] The present invention relates to a pull lever handle device, and is particularly characterized by the combination of the device and a click mechanism of its rotating shaft.

Conventionally, as a structure for imparting a click motion to the rotating shaft of a pull lever handle device, the rotating shaft is elastically sandwiched between leaf springs, so that it is difficult to reduce the width of the pedestal that supports the leaf spring.

Since the aluminum sash frame to which the pedestal is attached tends to be thin, conventional devices have difficulty attaching the pedestal to the narrow aluminum sash frame.

In view of the above, the present invention narrows the width of the pedestal on which the coil spring is provided by pressing the rotation shaft of the pull lever handle device with a coil spring to give the rotation shaft a click motion.

Examples of the present invention will be described in detail below.

In the drawing lever handle device shown in the figure, a lever handle 2 is mounted on a base 1 so as to be rotatable about a rotating shaft 3, and a pulling piece 4 is disposed between the handle and the base on a common axis with the rotating shaft. It is set up so that it can rotate.

The handle 2 can be rotated 180 degrees, but the pulling piece 4
can be rotated by 90', with a 90° play between them to prevent the handle from protruding sideways when in the open/closed position.

The pedestal 1 has an elongated shape, and a rectangular space 5 is provided on the back side of the pedestal 1.
is in great shape.

The rotation axis 3 of the handle passes through the center hole 7 of the top surface 6 of the base and extends to the back side of the base, and in the part surrounded by the space, two thousand faces 8 are parallel to each other and approximately perpendicular to the longitudinal direction of the handle. It is shaped by a relationship that intersects with

The opening of the space is closed by a back cover 9, which engages with the shoulder 10 of the pedestal, and a fixing ring 12 fixed to the rotating shaft 3 with a pin 11 holds the back cover and assembles the handle to the pedestal.・There is.

Two compression coil springs 13 are provided in the space 5 of the pedestal so as to sandwich the rotating shaft 3, and a U-shaped backing plate 14 is provided between the spring and the rotating shaft.

The pulling piece 4 has an arm 16 extending perpendicularly to the axis of the rotating shaft 3, and an engaging part 18 extending perpendicularly from the tip of the arm and engaging with the receiver 17. Pull relative to the frame.

In the figure, the handle 2 is in an unlocked position facing the longitudinal direction of the base 1 together with the pulling piece 4, and the flat part 8 of the rotating shaft 3 is engaged with the backing plate 14 and receives the pressing force of the spring 13, and the handle is in the unlocked position. Forcibly held in unlocked position.

The handle 2 can be rotated through 180°, while the pulling piece 4 can be rotated through 90°, with a play of 90° between them.

Therefore, the pulling piece 4 remains in the unlocked position until the handle 2 is rotated 90 degrees in the direction of the arrow from the state shown in the figure.

When the handle 2 exceeds 90 degrees, the pulling piece 4 follows the handle and rotates in the same direction as the handle.

When the handle has been rotated through 180° and reaches the position facing the longitudinal direction of the base 1, the pulling piece 4 reaches the locking position facing laterally at 90'.

While the handle 2 rotates 180 degrees, the rotating shaft 3 rotates with its arcuate surface 15 pushing against the backing plate 14 against the pressing force of the spring 13, so that the flat part 8 of the rotating shaft engages with the backing plate 14 again. The rotating shaft stops at the engaged position and is forcibly held.

When the handle 2 rotates from the locked position to the unlocked position,
Within the first 90° range, only the handle rotates;
When it exceeds ゜, the pulling piece also rotates following the handle and returns to its original position.

Note that 14' is a U-shaped spring holder that receives one end of the spring.

The present invention provides a pulling device comprising a lever handle 2 that can rotate approximately 180 degrees as described above, and a pulling piece 4 that has approximately 90 degrees of play with the lever handle and is rotated approximately 90 degrees. Plate for shaft 1
The lever handle is held in the locked position and the unlocked position by the engagement of the flat part 8 and the backing plate 14, which are sandwiched between two compression coil springs 13 via the lever handle 4 and parallel to the rotating shaft. Therefore, the lever handle rotates more smoothly than a lever handle using a leaf spring, and the lever handle with 90' of play makes it easier to pull the shoji.

In addition, a thousand planes 8 parallel to each other of the rotation axis 3 of the lever handle 2
The coil spring 13, which is inserted into the elongated space of the pedestal 1 along the longitudinal direction thereof, is located in a plane substantially perpendicular to the longitudinal direction of the lever handle. The width of the base can be made slightly larger than the diameter of the coil spring, making it narrower than that of conventional springs.

As a result, it becomes possible to narrow the width of the aluminum sash frame to which the pedestal is attached.
