存在する。 A cylindrical lock is a type of door lock that can be used for both final and temporary tightening with just a latch bolt, and when the inner handle is rotated,
A temporary locking structure in which the rotation of a spindle fitted and fixed to this handle operates a retractor housed in a lock case inside the door at its end, and the latch bolt engaged with this retractor is retracted to open the door. By operating the operation button or key provided on the handle, an interlocking member provided coaxially through the spindle is actuated, thereby blocking rotation of the handle and releasing the blocking structure. It is well known that There are various types of locks, including those with only a temporary tightening mechanism, those with a permanent tightening mechanism, and those with a fixed outer handle.

なかつたのである。[Problems that the invention aims to solve] By the way, in the case of a knob, it is necessary to turn it by grasping it, and it is impossible to turn it by pressing it with the elbow part like a lever handle. can be,
The use of a lever handle, which is used in other door locks, is desired in some cases. However,
If the grip ball is relatively large, like a knob, and has a shape that allows it to be attached by squeezing the exterior body,
It is possible to have a structure in which a cylindrical part is provided in the inner body and the spindle is attached to this cylindrical part, but the lever handle is made of a relatively small cylindrical part for attachment and a grip part that protrudes radially from this cylindrical part. Generally, the structure is integrally cast with zinc die-casting, etc., and it is not possible to attach the inner body with a cylindrical part to the cylindrical part, as in the case of a knob.From this point of view, the lever handle type cylindrical locks were not available.

In this case, a fixed tube that is fitted and fixed into the cylindrical part of the lever handle body is separately provided, and the spindle is fitted and fixed into this fixed tube, and the fixing between the fixed tube and the spindle is almost the same as before. Then, the locking portion of the retaining ring, which is provided at the intermediate portion by a spring bias so that the locking portion always protrudes radially outward from the notch hole, is fitted into the retaining hole formed in the fixed cylinder and fixed. On the other hand, in order to completely prevent the cylindrical part and the fixed cylinder from coming off, the structure is such that a locking pin is driven into a pin hole formed through both of them.
Furthermore, in order to completely prevent the locking pin from slipping out in the outward direction, the pin hole is countersunk at least at the inner opening of the fixing cylinder, and the pin end is caulked.

り止めとしている。 In the exploded perspective view of FIG. 1, reference numeral 1 denotes a lever handle body, which consists of a cylindrical part 2 for mounting and a grip part 3 protruding in the radial direction from this cylindrical part 2, and is integrally made by zinc die-casting or the like. It is cast. Reference numeral 4 denotes a fixed cylinder that is fitted into and fixed to the cylindrical portion 2, and 5 is a spindle that is fitted and fixed to the fixed cylinder 4. This spindle 5 has protrusions 5a, 5a for operating the retractor at the tip, and an axial groove 5b is formed at the bottom. This groove 5b
In the case of an outdoor spindle, for example, when a locking rod provided coaxially through the indoor spindle is pressed via an operation button protruding from the end surface of the knob, the end of the locking rod will fit into the indoor side. It is used to disable rotation of the outer lever handle and obtain a locked state. Pin holes 6 and 7 are formed in the cylindrical part 2 and the fixed cylinder 4 that is fitted and fixed therein. After the fixed cylinder 4 is fitted into the cylindrical part 2, a stop pin 8 is pressed into the pin holes 6 and 7 and driven. Fully fixed cylinder 4
is fixed to the cylindrical part 2. In order to prevent the locking pin 8 from coming off, the inner opening of the pin hole 7 formed in the fixing tube 4 is countersunk, and the inner end of the locking pin is caulked along this countersink. This prevents loosening due to vibration and ensures complete fixation of the fixed cylinder to the cylindrical part. Reference numeral 9 denotes a notch formed at the rear end of the fixed cylinder 4, which engages a rotation prevention protrusion (not shown) formed at the inner rear end of the cylindrical part 2, so that when the lever handle body 1 is rotated, The resistance to the applied rotational torque is shared. Fixed cylinder 4
The fitting and fixing of the spindle 5 and the spindle 5 is almost the same as the conventional method, and the retaining ring 12 is biased by a spring so that the locking part 11 always protrudes radially outward from the notch hole 10 in the middle part of the spindle 5. A stopper hole 1 formed in the fixed tube 4 when the fixed tube 4 is inserted into the fixed tube 4.
3 by fitting the locking portion 11 into it. In this embodiment, the retaining ring 12
and a spring 14 are provided separately, and the spring 1 is formed by winding the inner protrusion 12a of the retaining ring 12 in a U-shape at the middle part.
The retaining ring 12 is biased radially outward by bringing both end portions of the retaining ring 12 into contact with the edges of a notched groove 5c formed perpendicularly to the divided groove 5b.
A conventional spring retaining ring 22 in which a retaining ring and a spring are integrated may also be used. As shown in the figure, the locking portion 11 of the retaining ring 12 has a tapered surface 11a formed at the center of the upper surface in the direction of insertion into the fixed tube 4, and the tapered surface 11a is formed at the tip of the fixed tube 4.
A protrusion 15 that aligns with 1a is formed. Therefore,
When the spindle 5 is inserted into the fixed cylinder 4, the tapered surface 11a is pressed by the protrusion 15, and the locking part 11 can be inserted while being pushed down against the spring pressure, making installation convenient. . 16 is
A protruding part formed on the fixed cylinder 4 that protrudes inward,
When the spindle 5 is inserted, it is inserted into the split groove 5b to prevent rotation.
