Description

The present invention relates to a rolling element bell that can be used in a wide range of fields, such as doorbells, alarm bells, animal bells and doorbells.

Various bells have been proposed, such as doorbells that alert people to visits, alarm bells that alert people, bells for animal protection such as bears, bells as lucky charms, etc. It would not sound unless it was shaken, and the tone was also monotonous.

Patent Literature 1 discloses a bell that houses a rolling element in a space formed by a thin metal plate, and Patent Literature 2 discloses a bell toy that holds a ball between upper and lower resonators. Sound is produced by shaking.

Some conventional bells make a sound by hanging a weight with a string or the like and hitting a phosphorus portion with the weight. In this case, there is a problem that the period in which the weight swings is determined by the distance from the fulcrum to which the string is fixed to the center of gravity of the weight. In addition, in the type in which the weight is suspended, the angle at which the ball hits the inner wall of the phosphorus portion is constant. Furthermore, there is a problem that even if the phosphorus part is shaken, the weight must give energy exceeding the potential energy (up to the hitting bell part).

It is an object of the present invention to provide a bell that rings with a small amount of vibration and allows easy adjustment of sound volume and tone color.

The rolling element bell according to the present invention is a bell that rings when the entire bell swings, and includes a base portion and a phosphorus portion supported directly or indirectly by the base portion, and the base portion is a recess. The rolling element is placed so as to be able to roll in the recess, and the bell is shaken so that when the rolling element rolls to the peripheral edge of the recess of the base part, the phosphorus part is struck, The sound can be adjusted by the contact angle or height between the rolling element and the inner wall of the phosphorus portion.

Here, the rolling element refers to the one that rolls due to the vibration or shaking of the entire bell and hits the phosphorus portion, and there is no limitation on the shape as long as it rolls, but the one that is easy to roll is preferably close to a sphere.

Further, it is preferable that the base portion and the phosphorus portion are rolled together so as to have a predetermined gap or space, thereby improving the sound of the sound.

The present invention resides in that the rolling cycle (speed) of the rolling element such as a sphere is adjusted by the bottom surface shape (rolling surface shape) of the concave portion of the base portion.
In this way, the conventional bell is greatly influenced by the length of the suspension member, and it is difficult to adjust the sound. On the other hand, the present invention can be easily adjusted by the curvature of the bottom surface of the recess. is there.

In the bell according to the present invention, a rolling element such as a sphere rolls on a rolling surface formed of a concave shape formed in the base portion, and therefore, the rolling element is adjusted according to the shape of the rolling surface for ease of rolling and rolling speed. be able to.

Therefore, if the rolling surface is formed into a spherical shape with the lowest central portion and the curvature of the spherical surface is made small, the rolling element becomes difficult to roll, and the force that the rolling element hits the phosphorus part becomes so weak that the sound becomes small.

When the bell swing is small, no sound is produced by returning to the center before the rolling element hits the phosphorus part.
On the other hand, if the curvature of the rolling surface is increased to make it nearly flat, a sound will be produced even with small shaking.
The shape of the rolling surface does not necessarily have to be a spherical shape, and may have a groove that regulates the rolling direction of the rolling element, for example, it may be formed radially from the center toward the peripheral edge, or the groove may be spirally formed. It may be formed.

Further, if the bottom surface of the concave portion has a spherical surface portion having a predetermined curvature at least in the central portion, it is easy to adjust the rolling cycle of the rolling element and the strength hitting the phosphorus portion.

In the case of a hitting ball suspended by a conventional thread or the like, the angle of contact with the inner wall of the phosphorus portion is constant, whereas the bell according to the present invention has an inclination angle of the rolling surface of the base portion, Since the way of contact with the rolling elements changes depending on the angle of the inner wall of the phosphorus portion, the angle and the height at which the rolling elements hit can be adjusted.
Moreover, although the ringing method of the phosphorus portion varies depending on the size and material of the rolling elements, the rolling elements can be easily replaced.

In the present invention, the base portion may have stop means for stopping and placing the rolling element when the vibration or vibration applied to the bell is not more than a predetermined magnitude.
Here, the rolling element can be stopped by a method of providing a small depression in a part of the rolling concave surface of the base portion, for example, the central portion, or when the base portion is not a ferromagnetic material such as iron. In some cases, there is a method in which a magnet is embedded in the base portion or a magnet is disposed on the back side of the base portion.
In any case, the means is not limited as long as the rolling element does not move when the vibration or vibration of the bell is small.
In this way, the rolling element does not move with a small shake or shake, but becomes larger than a predetermined size, and the rolling element jumps out of the recess or comes out of the magnet and comes into contact with the resonator.

Further, the base part may be supported by an elastic body, or the base part may be supported by the elastic body and the base part may be adjusted in terms of its elastic modulus or the like.

The bell according to the present invention can be used as a single bell.
Further, it can be incorporated into a part of a product or attached to an attached body such as an entrance door.

The front door includes an open door that rotates in the front-rear direction and a sliding door that slides in the left-right direction. The sliding door swings and swings less than the open door.
Since the bell according to the present invention hits the phosphorus portion when the rolling element rolls on the upper surface of the base portion, a loud sound is generated even when the bell is attached to such a sliding door with a small swing.
In addition, it can be prevented from ringing by small shaking caused by wind.

When attaching the bell to the attached body when attaching the bell to the attached body with an elastic body, this elastic body amplifies the vibration and vibration of the bell,
Or conversely.
For example, when a bell is erected on the mounting portion via an elastic body, it acts to amplify the swing of the mounting portion, and when the bell is suspended with an elastic body under the mounting portion, the vibration is suppressed by the elastic body. Sounds long.
When attaching the bell which concerns on this invention to a door, you may attach to the handle which opens and closes a door.

In addition, by providing a control means for controlling or stopping the movement range of the rolling element that rolls on the base portion, it is possible to control the strength of the shaking and the volume of the sound, or to prevent the sound itself from being generated. Of course, the rolling element may be a magnetic substance, and the sound may be prevented from being produced by stopping the operation of the rolling element by using a magnetic force to attract the magnetic force from outside or inside the phosphorus portion. By such a control means, it is possible to prevent the sound from being emitted when the sound is unnecessary.

The bell according to the present invention can adjust the pitch, strength, timbre, and the like of the sound produced by adjusting how the rolling element hits the phosphorus portion.
In particular, the rolling cycle and speed of the rolling element can be easily adjusted by the curvature of the bottom surface, the rolling groove regulation groove, and the like.

Further, when the curvature of the rolling surface is increased to approach a flat shape, sufficient kinetic energy can be given even by fine oscillation, resulting in a loud sound.
It is easy to adjust the volume and tone of the sound by the elastic modulus of the elastic body that supports the base portion.

Furthermore, when the rolling element control means is provided, the rolling range of the rolling element and the rolling itself can be stopped.

Furthermore, the present invention can be easily configured by covering the bell portion with a cover and joining the base portion to the cover portion. In this case, if the bottom part of the base part is formed with a downwardly convex curved surface, the whole part can be shaken when placed on a flat surface. It can also be used as a rolling element bell that softens and soothes with sound.

Moreover, since it is covered with a cover, when used as a bear bell, there is no attenuation of sound due to contact, so it can be comfortably used even if it is put in a pocket or attached to a rucksack.

Specific embodiments of the present invention will be described with reference to the drawings. The drawing of FIG. 1 is an explanatory view of a vertical end view drawn with a freehand at the center. For the sake of brevity, the rolling elements (4) are omitted for the sake of description and are entered for explanation. The rolling element bell shown in the drawing is a rotating body whose axis is the vertical axis direction.

FIG. 1 is an explanatory diagram of freehand. Except for the rolling element (4), it is represented by a longitudinal center end view. This form consists of a base part (5) which covers the phosphorus part (1) with a cover (2) and is continuously connected to the cover (2). The rolling element (4) may be rolled by ringing with the holding hands (3) or the like, or attached to a sliding door or the like. Moreover, when the bottom part of the base part (5) is convex downward, it may be placed on a flat surface and rocked and squeezed like a rising and shaking swaying. In this case, the rolling element (4) rolls on the rolling surface (6) of the base part (5) and collides with the phosphorus part (1), so that it makes a sound and makes a comical movement. Can be obtained.

The material of the phosphorus portion (1) is preferably a metal, but there is no particular limitation, and it is sufficient that it functions as a bell. Further, the base part (5) and the cover (2) are preferably made of resin, but are not particularly limited. The cover (2) may cover the whole or may have a space. Those having a space exhibit the effect that sound is easily transmitted to the outside.
