Handheld and Remote-Controlled Bell

Abstract

To provide a bell that has both hand-operated and remote-operated functions.SOLUTION: A bell includes a bell body and a striker for striking the bell body, and further includes pressing means for operating the striker in the direction in which the bell rings, and a solenoid for operating the striker with electromagnetic force.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to doorbells such as counter bells and desktop bells.

Background Art

[0002] Conventional doorbells such as counter bells and desktop bells could not be rung unless they were placed at hand. (Patent Document 1) On the other hand, an electric doorbell that can be remotely operated by electromagnetic force could not be used as a counter bell. (Patent Document 2)

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to provide a bell having both functions of hand operation and remote operation.

Means for Solving the Problems

[0005] The hand and remote operation type bell according to the present invention includes a bell main body and a striker for ringing the bell main body, and is characterized by including pressing means for operating the striker in the direction in which the bell rings, and a solenoid for operating the striker by electromagnetic force.

[0006] For example, the pressing means is a shaft biased upward, the shaft has an acting portion that operates the striker in the direction in which the bell rings when the shaft descends, and the shaft is a mover of the solenoid or is connected to the mover. A structural example can be considered.

[0007] As the counter bell, it has a through hole in the center of a bowl-shaped bell body with an open bottom, and there is one having a push button inserted through this through hole. This push button is biased by a spring or the like in a direction to return upward. When this push button is pressed and pushed down, a striker biased in a direction away from the bell body is operated in a direction to ring this bell body. The present invention is characterized in that this push button is used as a mover (movable iron core) in a solenoid.

Effect of the Invention

[0008] In the present invention, since the shaft portion constituting the push button for manually operating the bell is used as the mover in the solenoid, not only the manual operation of ringing the bell by pressing the push button with a finger, but also an electric signal can be transmitted to ring the bell remotely. By combining the mechanism of the solenoid with the push button in this way, when the push button is pressed with a finger, this movement can be detected as a magnetic signal by the coil constituting the solenoid, and thus it can also be recorded as information data taken into a personal computer or the like and left in the record.

Mode for Carrying Out the Invention

[0010] An example of the structure of the manual and remote operation type bell according to the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show the case of manual operation, and FIG. 3 shows an example of remote operation by sending an electric signal. The bowl-shaped bell main body 11 with an opening at the lower side is supported by a support cylinder 12d erected from the base portion 17. The support cylinder 12d is provided at the central portion of the bell main body 11, has a shaft 12a supported therein so as to be vertically movable, and has a pressing portion 12 functioning as a push button on the upper end side of the shaft 12a. This pressing portion 12 is biased upward by a spring 12c fitted on the shaft 12a. Note that as long as the shaft 12a is supported so as to be vertically movable, it is not limited to this support cylinder. Further, an operating portion 12b for operating the striker 13 is provided on the shaft 12a.

[0011] The example shown in FIG. 1 is an example of a counter bell, and the striker 13 is pivotally attached to a support member 13a provided inside the bell main body 11 using a pivot portion 13b, and the striker 13 is biased in a direction away from the bell main body 11 by a spring or the like (not shown). When the push button is pushed downward, the operating portion 12b provided on the shaft 12a descends, and by pushing down the operating rod 13c, the striker 13 hits the inside of the bell main body 11, and the bell rings. When the finger or hand is released from the push button 12, the push button 12 returns to its original position by the spring 12c.

[0012] In the present invention, the tip portion 112a of the shaft 12a serves as a mover (movable iron core) and is inserted inside the solenoid coil 14. Here, the mover 112a only needs to be movable by a magnetic field, and it is not necessary for the entire shaft 12a to be a magnetic material. A magnetic material may be provided as a part of the shaft 12a, or it may be a magnet having a magnetic force. A fixed iron core 15 is attached to the lower side slightly away from the tip of the shaft 12a. By passing an electric current through the solenoid coil 14, it functions as a solenoid, the shaft 12a descends by an electromagnetic force, the striker 13 hits the inside of the bell main body, and the bell rings. The operation of this solenoid can be remotely controlled by sending an electrical signal to the control unit 16. Also, when the bell main body is manually rung, the movement of its shaft 12a can be detected by the solenoid, and the signal can be taken in as information by an external personal computer or smartphone via the control unit 16. Furthermore, by operating the solenoid with an external signal, various applications regarding the usage method of the bell become possible, such as controlling it in a direction that prevents pressing the push button by hand.

[0013] FIG. 4 shows an example of a striker, in which overlapping strikers 23 are suspended by a suspension member 23a such as a string or wire. In this case, when the shaft 12a is pressed with a finger or descends by an electrical signal, the acting part hits the striker 23 suspended by the suspension member. As a result, the striker 23 swings left and right and hits the inside of the bell main body, ringing the bell main body.
