Description

  The present invention relates to a lever handle for a door installed in a house or the like, and more particularly to setting an angle of a lever handle.

  2. Description of the Related Art Conventionally, a structure provided with a lever handle that is rotated in a door installed in a house or the like is known. A lock box is embedded inside the door, and a latch bolt is projected and retracted at an end surface of the door on the door end side (see, for example, Patent Documents 1 and 2).

  When opening the door, it is possible to open the door by rotating the lever handle so as to push down the tip of the lever handle and immersing the latch bolt into the door.

  In addition, when the door is closed, the latch bolt is projected by the biasing force of the spring in the lock box, and the latch bolt is pushed into the strike on the door frame side to maintain the door closed. Is done.

  In the configuration including such a lever handle, as shown in the conventional example of FIG. 7, the through hole 91 in the thickness direction of the door is hidden by a plate-shaped receiving seat 92, and the lever handle 93 is located at the center of the receiving seat 92. In general, the rotating base end portion 93a is configured to be positioned.

  Further, as shown in the conventional example of FIG. 7, the lock box 94 housed in the door is provided with a rotary hub member 96 for advancing and retracting the latch bolt 95 in conjunction with the turning operation of the lever handle 93. Is provided. The hub member 96 is abutted against the stopper by the urging force of the spring 97 and is set to a standby angle. At this standby angle, the lever handle 93 becomes horizontal and the latch bolt 95 protrudes. Further, the hub member 96 is formed with a square hole 96a, and the square hole serving as the pivot shaft of the lever handle 93 is inserted into the square hole.

JP 2011-47175 A JP 2001-323707 A

  As described above, when the hub member 96 is at the standby angle by the biasing force of the spring 97 provided in the lock box 94, the lever handle 93 is installed so as to extend substantially horizontally from the base end portion toward the tip end portion. The Thus, by installing the lever handle 93 so as to be substantially horizontal, the operation of pushing down the lever handle 93 can be easily performed. Moreover, by installing it substantially horizontally, it is possible to give a good impression that the lever handle 93 is correctly constructed.

  Here, the angle of the lever handle 93 in a state where the door is closed, that is, in the standby state is set by the angle of the hub member 96 in the standby state, and the angle of the hub member 96 in the standby state. Is determined by the biasing force of the spring 97.

  For this reason, when the urging force of the spring 97 decreases with time, the angle of the hub member 96 in the standby state is affected, and consequently the angle of the lever handle 93 in the standby state. That is, when a long period of time elapses after installation, the lever handle 97 is not substantially horizontal, and the tip end side is lowered.

  In consideration of such a decrease in the urging force of the spring 97, there is known a method in which the lever handle 93 is installed with the tip end side slightly raised. For example, even when the angle θ of the square hole 96a of the hub member 96 is set, an inclination θ that slightly increases the tip end side of the lever handle 93 is provided at the beginning of installation, and even if the urging force of the spring 97 is reduced due to aging, the lever This is a measure to keep the handle 93 substantially horizontal.

  Here, when the tip end side of the lever handle 93 is slightly tilted and installed, as shown in FIG. 7, when the door is viewed from the front, the surface of the seat 92 is not rotated by the lever handle 93. When it is larger than the moving base end portion 93a, the presence of the seat 92 may be conspicuous, and the inclination of the lever handle 93 becomes inconspicuous and can be seen as being installed substantially horizontally. In particular, as shown in the example of FIG. 7, when the seat 92 has a round shape, a specific angle does not remain in the impression in the relationship between the outlines of the lever handle 93 and the seat 92, The angle will be inconspicuous.

  On the other hand, there are various demands for the seat 92, for example, by making the size of the seat 92 less conspicuous and realizing a clean design in which the seat 92 is not noticeable.

  However, if the seat 92 is made inconspicuous, the inclination of the lever handle 93 becomes conspicuous, and there is a concern that the impression of the lever handle 93 may be reduced.

  Also, for example, when it is desired to realize a design with a sense of unity between the seat and the lever handle by matching the contour line of the seat with the contour line of the lever handle in front view, Cannot be matched. For this reason, the seat design has to take into account the inclination of the lever handle.

  As described above, it can be said that there was a design restriction for the seat in relation to the fact that the lever handle is tilted.

  In view of the above problems, the present invention enables the lever handle to be installed so as to extend at a predetermined angle (for example, horizontal), and removes the design restrictions on the seat due to the angle of the lever handle. It proposes a new technology.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, as described in claim 1,
A lever handle structure that is provided so as to be rotatable with respect to a seat installed in the door body and is urged to rotate so as to maintain an angle in a standby state by an urging force of a spring,
The lever handle has an arm portion, a rotation base portion, and a rotation shaft portion,
The rotation shaft portion is provided to protrude from the rotation base portion toward the door body side,

Further, as described in claim 2 , in the front view, the seating surface is included in the range of the rotation base that overlaps the seat.

  As effects of the present invention, the following effects can be obtained.

  According to the present invention, it is possible to install the lever handle so as to extend at a predetermined angle (for example, horizontal), and it is possible to remove the design restrictions on the seat due to the angle of the lever handle. Further, since the setting of the specified angle is realized by a lever handle and a seat that are arranged close to each other, more accurate angle setting can be realized. Further, the angle setting by the mechanism in the lock box inside the door body is unnecessary, and the angle can be set by a member arranged outside the door body, so that the adjustment work can be easily performed.
