Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an assembly structure of a round seat for a door handle. In this specification, the terms "door handle" or "handle" are used as a general term for lever handles, knobs, and other handles that actuate latches or various hanging fittings in doors or sliding doors.

[0002]

2. Description of the Related Art As a conventional assembly structure of a round seat for a door handle, as shown in Japanese Utility Model Publication No. 6-40295, for example, a front circular seat plate fixed to the surface of a door and a thin seat plate are used. A bottomed cylindrical cover member is fitted and engaged by a plurality of detachable engaging means formed by a protrusion and a recess provided between the outer peripheral portion of the seat plate and the inner surface of the body of the cover member. I can list the ones I made.

[0003] One of those disclosed in the publication is that an engaging projection is provided on an inner peripheral surface of a cover member, and an insertion guide concave portion for positioning the engaging projection with respect to a seat plate and an engaging projection fitting attachment member. The invention is provided with a fitting recess, a neck part connected to the engagement recess and a spiral groove connected to the neck part, that is, the invention, and another one disclosed in the publication is an engagement protrusion on the cover member. And a recess for tool insertion and a seat plate provided with an engagement recess and a tool receiving recess, which are mentioned as conventional examples.

[0004]

However, according to the conventional assembly structure of the round seat for the door handle, the round seat including the seat plate and the cover member must be provided with a large number of recesses having different functions. In addition, it is difficult to process, and unless the processing accuracy is high, it cannot be easily and reliably engaged and disengaged.
Alternatively, when removing the cover member, there is a problem that the surface of the cover member, the seat plate or the door is easily damaged by a tool.

The present invention has been proposed in order to solve such problems. That is, the tools are simple in structure, need not be considered so much in machining accuracy, can easily and surely engage and disengage the cover member and the seat plate, and attach and detach the cover member. The purpose is to make it unnecessary to use by hand.

[0006]

In order to achieve the above-mentioned object, an assembly structure for a round seat for a door handle according to the present invention has a front circular seat plate fixed to the surface of a door and a thin bottomed cylindrical shape. Door handle adapted to be fitted and engaged with the cover member by means of a plurality of detachable engaging means formed by projections and recesses provided between the outer peripheral portion of the seat plate and the inner surface of the body of the cover member. In the mounting structure of the round seat for use, the engaging means are provided in pairs near both ends of the diameter of the seat plate, and the engaging means form a pair of engaging means portions at about 90 ° around the central axis of the seat plate. The seat plate is provided with a pair of cutouts at the shifted angular position, and a portion corresponding to the pair of cutouts of the seat plate in the body portion of the cover member is pressed toward the central axis of the seat plate to remove the cover member. To spread each engagement means part in the body part almost in the diametrical direction Ri, is characterized in that so as to resiliently disengage the cover member to the seat plate.

[0007]

The operation of the present invention will be described with reference to FIGS. In order to fit and fix the cover member 2 to the seat plate 1 fixed to the door 10 with the screw rods 13, 14, etc., the pair of notches 11 of the seat plate 1 in the body portion 21 of the cover member 2, A portion corresponding to 11 is pressed inward by fingers as shown by an arrow A, and each engaging means portion in the body portion 21 of the cover member 2 is expanded in a substantially diametrical direction.

At this time, the cover member 2 is elastically deformed and its front outer shape becomes an elliptical shape as shown by the chain double-dashed line in FIG. 1. Therefore, the cover member 2 is fitted into the seat plate 1 in this state. .

In this fitting, the projections 31 of the respective engaging means 3 are fitted with each other (the outer peripheral portion of the seat plate 1 in the illustrated example).
Since it passes a little away from the protrusion 31, the protrusion 31 does not collide with each other and the fitting is not hindered.

Further, the portion of the body portion 21 of the cover member 2 whose diameter is narrowed, that is, the portion which is pressed in the direction of the arrow A is escaped from the collision in the notches 11 and 11 of the seat plate 1, so that it is inserted. Is achieved smoothly.

Next, when the fingers are loosened to release the cover member 2 from the pressed state, the front outer shape of the cover member 2 elastically returns to the circular shape as shown by the solid line in FIG. The protrusions 31 and the recesses 21 are engaged with each other, so that the cover member 2 is engaged with the seat plate 1 in a fitted state.

On the contrary, when removing the cover member 2 from the seat plate 1, the body portion 21 of the cover member 2 may be pushed inward with fingers as shown by an arrow A in FIG. Due to this pushing, the front outer shape of the cover member 2 is elastically deformed into an oval shape, so that the engagement state of the engaging means 3, 3 is released, and the cover member 2 can be easily separated from the seat plate 1.
