Patent Application
20120305601
The present invention relates to electric vibrating devices.
There are numerous forms of dispensing devices for condiments such as salt, pepper, herbs and the like, which are provided with perforated caps, through which the contents are dispensed by inverting the dispenser and manually shaking it so that a portion of the contents drops out through the perforations, as required. However, it may be more convenient to dispense with a device that can mechanically dispense.
There are also to be found numerous forms of dispensing devices, such as for seeds and grain, which employ a form of electrically-induced vibration to dispense the contents.
U.S. Pat. No. 3,435,994 to Arnold Frede describes a vibrating dispenser having a lower chamber provided with a battery-driven motor having a rotatable shaft on which is mounted an eccentric weight. A support disk is disposed in the bottom chamber, the disk having an opening and an actuating pin is disposed therethrough and is freely vertically movable. The motor is on the disk. When the dispenser is lifted from the surface the pin is released and drops to close a circuit, whereupon the eccentric weight is caused to rotate on its shaft, creating a constant vibration for the dispenser. The vibration stops only when the dispenser is replaced on a flat surface.
Some disadvantages of the device described in U.S. Pat. No. 3,435,994 are that it is somewhat wasteful of the battery charge to have the motor operate in non-dispensing positions, which may also be annoying or cause the user to suspect something is wrong with the dispenser. The proper operation of the dispenser is also limited to use with a flat and hard surface for resting the dispenser, and the pin might catch on surfaces such as tablecloths and bags or disfunction due to dirt, lint etc accumulating on the pin, motor, electrical connections etc.

According to one aspect, a vibrating device is provided, comprising: a body comprising a first chamber, the first chamber having a housing therein and a bottom open end; a base securable to the bottom open end; a serial electrical circuit comprising: a battery; an electric motor secured to the housing, the motor provided with a rotatable shaft having an eccentric weight mounted thereon, and a bulb having: walls; a first and a second electrical bulb wire, each extending through a wall of the bulb and with an end extending into the bulb, and at least one bead in the bulb, the bead made of high electric conductivity material and the walls made of low electric conductivity material, wherein the bulb is configured so that when the device is tilted beyond a predetermined angle, the bead moves and comes into simultaneous contact with the bulb wires, whereby the motor and the battery are electrically engaged, allowing the device to vibrate, and when the device is below the predetermined angle, the device does not vibrate.
in
Disposed within the first chamber 26 is the bulb 30, the motor 40, and battery 50. The chamber 16 bordered by the top open end 17 is hereinbelow referred to as the second chamber.
a shows in a greatly enlarged view the bulb 30. A drop of mercury 31 rests on the bottom of the interior space 36 of the bulb 30. Note the vertical and unfilled orientation of the bulb 30 in this figure and in
The bulb wires 34a and 34b may have different lengths in the bulb 30, as indeed shown in the figure, but in other embodiments may have similar or identical lengths. The length of the wires 34a, 34b and the dimensions of the bulb will affect the tilt angle at which the device is activated to vibrate.
Referring now to
In some embodiments (not shown) the bulb is not in the first chamber, for example it may be placed in an external alcove in the body, such that it can be manipulated by a user without need to access the first chamber. A user may thereby adjust the tilt angle at which the vibrating commences. This may be done simply by changing the position of the bulb relative to the body.
When the bead is a mercury drop 31, it is perhaps preferable to able to have the bulb 30 inside the first chamber 26, for safety reasons. Other beads such as one or more iron beads, or graphite powder, may be preferable to a mercury drop in some embodiments, such as ones with the more easily accessible bulbs.
In some embodiments (not shown), the electrical circuit further comprises a switch configured to allow the device to be turned on and off by a user, which may be handy when people such as babies are tempted to mishandle the device.
Some embodiments (not shown) may further comprise means such as sockets available to a user, that allow the battery of the device to be electrically chargeable.
In some embodiments (not shown), the device further comprises means for controlling the vibrations of the device, such as voltage controllers, alternative batteries and adjustable resistors as part of the electrical circuit. In a salt/spice dispenser, the vibration intensity or strength may determine heavy or light sprinkling of the salt/spice, according to the user's taste.
In some embodiments (not shown), the electrical circuit further comprises means for warning a user that the perforated cap is not secured to the top open end, for example in a salt shaker such means may save a user for inadvertently ruining a food preparation due to insecure fastening of the cap after filling with salt. For example, the cap and the top open end may simply have contacts leading by wires to adjoin the electrical circuit, such that a red light and/or sound alarm is turned on when the cap is improperly secured, and/or a green light is turned on when the cap is properly secured. Furthermore, the device may thus be set to vibrate only when the cap is secured to the top open end.
Preferably, the device is impact resistant, for example to help protect it from damage from inadvertently falling on the floor. Preferably, at least the body 12, base 18 and cap 22 are made of impact-resistant material. The housing 60 may also be made of impact-resistant material.
In some embodiments, the body has a roll-resistant shape to help preventing the device from falling and breaking.
The scope of the present invention is defined by the appended claims and includes both combinations and sub combinations of the various features described hereinabove as well as variations and modifications thereof, which would occur to persons skilled in the art upon reading the foregoing description.
In the claims, the word “comprise”, and variations thereof such as “comprises”, “comprising” and the like indicate that the components listed are included, but not generally to the exclusion of other components.
