JPH0726801A - Embedded type knob lever of door - Google Patents

Abstract

PURPOSE:To prevent a knob lever from projecting out on the surface of a door and, what is more, the enable the door to be opened more easily with either a right hand or a left hand. CONSTITUTION:This embedded knob is formed with a knob lever case 1 fixedly buried in a door and a shutter plate 9 which is inserted into the knob lever case 1 under a spring pressure and buried inside under a depressing force of a finger in such a state that an opening unit of the case 1 may be closed. A window hole is bored on two sides opposed to the knob case 1, where the window hole is designed to hook the finger which has pressed down the shutter plate 9. This construction makes it possible to open the door easily merely by pressing the shutter plate 9 with either a left hand or a right hand irrespective of either hand, and what is more, enhance the outside view more clearly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buried handle for a door in which the handle does not project on the surface of the door and can be easily opened by either the left or right hand.

[0002]

2. Description of the Related Art If a handle of a door projects from the door surface, the appearance of the door may be impaired, or the handle may collide with an adjacent door to damage the door. In such a case, a handle may be provided so as to be buried in the door. The conventional buried handle is slidably buried in the door body, and if necessary, the buried grip is picked out to open the door, or a hollow for catching fingers is inserted into the door in advance. Is forming.

[0003]

However, the conventional buried type handle requires a number of steps to pick up the buried handle each time it is operated, and in the method of providing the depression for the finger hook, this depression is always exposed and the door is closed. The appearance is spoiled and the door design is limited.

The present invention does not expose the recess to the door,
Moreover, the purpose is to open the door easily.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and is a handle case that is embedded and fixed in a door, and is inserted into the handle case under spring pressure to push fingers. It is composed of a shutter plate that is designed to immerse from the closed state of the handle case with pressure, and a window hole for catching the finger that pressed down the shutter plate is punched on the two opposite side surfaces of the handle case. The summary is

[0006]

[Operation] In addition to burying a handle case that is box-shaped in a part of the door frame and has perforated window holes for hooking fingers,
A shutter plate that closes the opening surface of the handle is fitted into the box-shaped handle case under spring pressure. The outer peripheral front surface of the opening of the handle case is attached to the door so as not to project from the door surface, and the shutter plate is housed in the handle case so that it does not project even if the shutter plate is recessed against the spring pressure. This allows the shutter plate to be pushed into the handle case against the spring pressure when the shutter plate is pressed with fingers, and the fingers pressing the shutter plate can be hooked in the window holes of the handle case. If you pull it, the door will open. Moreover, the shutter plate is pushed down regardless of whether the hand pressing the shutter plate is the left hand or the right hand, and in that state the tip of the finger can be locked in the window hole on either side of the handle case, so the door opening operation can be performed. The door is simple and normally closed with a shutter plate, so the appearance of the door is not damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The buried handle of the door of the present invention will be described below with reference to the illustrated embodiment. In the figure, reference numeral 1 denotes a box-shaped handle case which is embedded in a door or the like and fixed by a screw and has a size suitable for opening a door by inserting fingers or the like. The handle case 1 is made of aluminum or aluminum alloy. In addition to such metal as described above, it is molded using synthetic resin or the like. The handle case 1 is box-shaped and has an opening at least on the front surface, that is, on the front surface side of the door when embedded in the door D. The inner peripheral flange 2 and the outer peripheral flange 3 are provided on the inner peripheral side and the outer peripheral side of the opening, respectively. And case are integrally formed, and handle case 1
When embedded in the door, the outer peripheral flange 3 is brought into contact with the outer peripheral outer surface of the mounting hole H formed in the door so that the handle case does not further sink into the door.

Window holes 4 and 4 are formed in two opposite side surfaces of the handle case 1, for example, side surfaces in the longitudinal direction of the handle case as shown in the drawing. The size of the window hole 4 is determined appropriately so that at least the tip of the finger is inserted and the operator can easily open the door by hooking the finger in the window hole.

Further, on the bottom surface 5 of the handle case 1, there are provided a spring stopper 6 for supporting one end of the spring 8 so as to lock or prevent the position from shifting, and a guide hole 7.

A shutter plate 9 which closes the opening is fitted in the handle case 1. The shutter plate 9 is slidable in the handle case so that it can be retracted. The shutter plate 9 is locked at its outer peripheral portion with the inner collar 2 so as not to project outside the handle case even if the elastic force of the spring 8 is received. Do like this.

When the shutter plate 9 is pressed, it is pushed down while maintaining the horizontal position so that the shutter plate 9 is immersed in the handle case.
As shown in FIG. 5, a guide rod 10 is provided on the back surface of the shutter plate, and the guide rod 10 is attached to the guide hole 7 of the handle case.
The shutter plate is inserted into the inside so that the shutter plate can be stably immersed.

If the guide rod 10 is not provided,
As in the embodiment shown in FIG. 4, the four edges of the shutter plate are bent in a stepped manner, and when the four edges 9a are brought into contact with the inner flange of the handle case, they become horizontal, and therefore when the opening is closed, they become horizontal. However, it is not always horizontal when pressed.

As the spring 8 interposed between the shutter plate 9 and the bottom surface 5 of the handle case, one coil spring is used in the embodiment shown in FIGS. 1 and 4, but as in the embodiment shown in FIG. It is also possible to arrange and use two of them in parallel.

Further, a kick spring 1 is used instead of the coil spring.
It is also possible to use 1. Both ends of the kick spring 11 can be directed in the same direction, or they can be arranged symmetrically. When the kick springs are arranged in the same direction as shown in FIG. 6, the shutter plate tilts toward the side that receives the pressing force, is immersed in the handle case, and is pushed by either the left hand or the right hand. The shutter plate tilts and retracts in the correct direction, and it is easy for fingers to get into the window holes. Further, as shown in FIG. 7, when the arrangement direction of the kick springs is symmetrical, the shutter plates are always kept parallel and are sunk in the case, and have the same action as when the guide rod is used.

[0015]

The buried handle of the door of the present invention is a handle case that is embedded and fixed in the door, and is inserted into the handle case under spring pressure, and the opening of the handle case is closed by pressing force of fingers. It is formed with a shutter plate that is designed to be immersed from the state, and a window hole is formed on the two opposite side surfaces of the handle case for catching the fingers that pressed down the shutter plate.Therefore, provide a recess on the door surface. There is also the advantage that the door can be easily opened with either the left or right hand by simply pressing the shutter plate, regardless of the left hand or the right hand, and the appearance can be cleaned.
