SOLUTION: A lever 3 is extended on a ring-like member 2 in an auxiliary lever 1, a stop screw 5 is provided through a resilient body 4b on both the sides of the root part of the lever 3 of the ring-like member 2, and the resilient body 4a is interposed at the opposite position. A pad plate 6 is interposed between the stop screw 5 and the resilient body 4b so that the edge of the stop screw 5 does not bite into the resilient body 4b. An inward rib 8a is formed on the inner peripheral edge of an inlet in which the ring-like member 2 is fitted to a knob 7, the inside diameter is equal to or slightly larger than the outside diameter of the knob 7. A rib 8b is also formed on the reverse side, and the inside diameter is smaller than the outside diameter of the knob 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary lever of a door knob for switching from opening and closing of a door by a knob to opening and closing of a door by a lever.

[0002]

2. Description of the Related Art Knobs have been attached to doors for opening and closing the doors. However, with the aging and welfare measures or the upsizing of houses, doors can be opened and closed by operating levers and handles. It has been adopted.

Under these circumstances, there has been a demand for a new type of door which can be opened and closed by a lever, instead of the conventional type which can be opened and closed by a conventional knob.

[0004]

In order to fulfill the above demand, the entire door must be replaced, which not only increases the economic burden, but also causes the balance between the old house and the replaced door to collapse and return to an ugly state. There are problems such as becoming.

The present invention has been made in view of the above problems, and has been made to provide an auxiliary lever of a door knob for improving a door which can be easily opened and closed by lever operation without imposing an economic burden and without breaking the balance of a house. Is what you do.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a lever is extended from an annular member fitted on a knob of a door, and the lever is located at least on the front side of the door knob of the annular member. An auxiliary lever having an inward rib formed on a peripheral edge thereof, and means for fixing the auxiliary lever to the door knob, wherein the means for fixing the auxiliary lever to the door knob is an elastic member provided between the annular member and the door knob. , Or fixed by an eccentric cam mechanism through an elastic body between the annular member and the door knob.

[0007] With the above configuration, the door can be changed to a door that can be opened and closed easily by operating the lever without imposing a large economic burden, without breaking the balance of the house.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings.

[First Embodiment] FIGS. 1 and 2 show a state in which the auxiliary lever of the first embodiment is applied to a bowl-shaped knob. The auxiliary lever 1 includes an annular member 2 having a lever 3 extending therefrom.
A set screw 5 is provided on both sides of the base of the lever 3 via an elastic body 4b, and an elastic body 4a is interposed at a position facing the set screw 5. A contact plate 6 is interposed between the set screw 5 and the elastic body 4b so that the tip of the set screw 5 does not bite into the elastic body 4b.

An inward rib 8a is formed on the inner peripheral edge of the entrance where the annular member 2 is fitted to the knob 7, and its inner diameter is equal to or slightly larger than the outer diameter of the knob 7. Similarly, a rib 8b is formed on the opposite side, and the inside diameter is smaller than the outside diameter of the knob 7 so that the annular member 2 does not pass through and can be positioned.

FIG. 3 shows a state in which the auxiliary lever of the first embodiment is applied to a round knob, and the configuration is exactly the same as in FIGS.

In the above embodiment, the annular member 2 is fitted on the knob 7, the elastic members 4a and 4b are interposed between the annular member 2 and the knob 7, and are screwed through the backing plate 6 to assist. Lever 1 is attached to knob 7. At this time, the rib 8a comes into contact with the outer periphery of the front surface of the knob 7 and is positioned and does not pass through.

[Embodiment 2] FIG. 4 shows Embodiment 2 and the basic configuration is the same as that of Embodiment 1. Therefore, only different points will be described.

An eccentric cam 10 integral with a shaft 9 is rotatably provided at the base of the lever 3, and a handle 12, which can be raised and lowered around a pin 11, is connected to the shaft 9. The cam 10 comes into contact with the convex piece 14 of the fixing bracket 13 to which the elastic body 4b is attached, and the eccentric cam 10
By being rotated by 2, the fixture 13 moves forward and backward, and the auxiliary lever 1 can be fixed or removed. When the auxiliary lever 1 is in the fixed state, the handle 12 is tilted down, and the fixed state is maintained by fitting the handle 12 into the recess 15.

According to the above embodiment, the annular member 2 is
The auxiliary lever 1 is fixed by turning the handle 12 to advance the fixing bracket 13 and fitting the handle 12 into the recess 15 of the lever 3. The auxiliary lever 1 can be easily removed by the reverse operation.

[0016]

As described above, according to the present invention, the door can be opened and closed by operating the lever without incurring a large cost and without breaking the balance with the conventional door.
