Description

Motion detection bicycle safety lamp and its usage {MOTION SENSITIVE BICYCLE SAFETY LIGHT AND METHOD OF USING SAME}

Several types of motion detection switches have been proposed for many years. In some types of switches, the ball or piston moves inside the cylindrical casing. In some switches, a ball of magnetic material is held inside a cylindrical passage in a nonmagnetic casing and is moved from the contact by a permanent magnet rod located in the casing perpendicular to the passage. When an impact is applied, the ball is driven by a contact to connect a switch. Alternatively, the switch may be closed using a single contact and conductor.

In another type of switch, steel balls are retained relative to the inverted circuit board, and conducting wires pass through the circuit board due to the large magnet on the opposite side of the circuit board. When agitation or vibration is applied, the steel ball passes and moves the casing away from the circuit board, disconnects the contact and alerts.

In another type of switch, a nonmagnetic and electrically conductive ball is suspended inside a nonmagnetic and nonconductive casing filled with a nonconductive magnetic fluid, and a contact portion protrudes into one end of the casing. . A permanent magnet may be disposed at one end or both ends of the casing, and a cylindrical hollow magnet may surround the casing including a region including a weight and a contact portion. When an impact is applied to a vehicle with a sensor, the additional contact is brought into contact, and a circuit is connected so that, for example, the airbag is activated.

In another type of switch, a permanent magnet is held that is movable in place in the nonmagnetic casing by a magnetic yoke. As the magnet moves, it hits the surface of the casing, rupturing the formed magnetic circuit and changing the reed switch from the on position to the off position. Proposed applications include seismic sensing or elevator load sensing.

In another type of switch, a permanent magnet is placed in an electrically conductive cover of a conductive copper alloy housing, which is held in an off position by a ring-shaped attractor and a coil, i.e. a braking force. do. For example, when an automobile is impacted, the magnet is moved away from the braking force to contact the conductor and connect the circuit.

In another type of switch, the magnetizing vibrating piston disposed at the center of the apparatus is held in an inoperative state by the reaction on the magnetic concave body. When a frictional force or impact is applied, the piston is moved and held against the plug to connect the circuit via contact action, such as an ignition cutoff switch in the event of a car crash.

Also described is a spherical piston biased relative to the piston seat by a magnet disposed opposite the piston seat. When an impact is applied, the piston preferably moves through a damping fluid, closing the circuit by impact contact. In another type of apparatus, a movable weight member carrying a contact portion is held in an off position by a spring. When the member moves due to acceleration or deceleration, the member comes into contact with the stationary contact.

In different types of devices, a substantially balanced mass is mounted to pivot about an axis, and a pair of electrical contacts are provided to pivot about an axis. The pair of electrical contacts is provided with at least one contact which lies in the pivotal movement path of the mass. An electromotive force source and irradiation means are connected to the contact means, and the contact means lights up by connecting the irradiation means only when the equilibrium mass is angularly accelerated.

In another type of device, the housing supports a power source and a light source that is electrically connectable. The operation switch is switched between the open position and the connected position in response to the movement of the housing member. The switch may be a pivotally supported member, an elastic member or a moving (ball bearing) member. A magnetic member slidably disposed in a coil or piezoelectric power source may serve as the power source and the switch. In other arrangements, the reed switch used with a wear or garment is operated by a magnet that is movable by friction, the magnet being in the on position where the reed switch is connected by the magnet and the reed switch being opened by the magnet. It is movable between the off positions. The magnet may be biased or air driven to an off position by a compression spring or magnet.

Various devices have been proposed for use as bicycle safety lights. One type of device is a flashlight that is fixed to the wheel spokes of a bicycle. The flashlight may be secured to a bracket mounted to the spoke so that the light from the flashlight is directed radially outward. Background Art It has been proposed to use a string of lights connected to a battery and flashing by a toggle switch to entangle the spokes of a bicycle wheel. Another type of device provides a light emitting diode (LED) strip in a transparent tube mounted on the spokes of the bicycle wheel, mounts a battery power pack on the wheel axle, and electrically connects the wheel to the light emitting diode. do.

In another device, a traffic light is provided to the wheel of the bicycle and the battery is fixed to the frame of the bicycle. The conductive plate is mounted to the nonconductive disc on the wheel hub. By allowing the spring to maintain an electrical circuit relative to the brush, the brush is in electrical contact with the conductive plate as the wheel rotates.

Another bicycle lamp includes a refracting housing in which a battery and a lamp mounted on a bicycle wheel are incorporated, a circuit including light emitting means for turning on a light source intermittently, and an operation sensor for operating the light emitting means such as a mercury switch. There is a bicycle equipped with.

In portable lamps and reflectors used for spokes of bicycle wheels, centrifugal force switches are used to complete the electrical circuit between the light source and the power supply. This centrifugal force switch is actually a mechanical switch, and is further provided to contact the strut so that the lamp is turned on when the centrifugal force is applied to complete the circuit.

In a back configured to be connected to the spokes of a bicycle wheel, the battery of the back is oriented radially inward of the bulb with respect to the axis of the wheel. The switch springs may disengage the battery from contact with the bulb when the wheel is not rotating, but may bias the battery in electrical contact with the bulb in response to centrifugal force.

In bicycle stabilization, the fitting body is configured to be screwed onto the male threaded portion of the bicycle wheel air valve. A safety lamp body equipped with a light bulb, a battery and a switch is fitted to the fitting body. When the fitting is screwed into the air valve, a switch is operated to light the bulb.

1A-1C are cross-sectional views of motion detection switches useful in the present invention. In these figures, the same reference numerals are used for the same components.

In FIG. 1A, the motion detection switch 10a has an elongated casing 12 terminated at one end with a flange 13, a magnetic body 14 such as a steel ball or a soft iron ball, and a permanent magnet 15. This is included. Conductors 16a, 16b, sometimes also referred to as conductors, extend through the flange 13 and the ends of the casing 12 at a distance.

When the switch 10a is in the off position, the magnetic body 14 remains spaced apart from the conductors 16a and 16b by the magnetic field generated by the permanent magnet 15. When the switch 10a receives a motion such as a centrifugal action or a josling motion, the magnetic body 14 moves to the position with respect to the conductors 16a and 16b, as indicated by the dotted line, and thus the conductors 16a and 16b. Contact the inner wall of the casing 12. At least the outer surface of the magnetic body 14 or at least the inner surface of the casing 12 is electrically conductive to complete the circuit with the conductors 16a and 16b. The electrical conductivity of the magnetic body 14 can be enhanced by known methods such as coating with copper or aluminum, for example. Similarly, the inner wall of the casing 12 may be coated with copper or aluminum, or the casing 12 itself may be molded from a conductive material such as copper, aluminum or brass.

In FIG. 1B, the motion detection switch 10b is configured similarly to the motion detection switch 10a except that the conductor 10b has been replaced by a conductor 16c abutting the outer wall of the elongated casing 12. . As shown in FIG. 1A, the permanent magnet 15 is preferably in contact with the flange 13. In this embodiment, the casing 12 needs to be electrically conductive, but the magnetic body 14 need not be electrically conductive. The electrical conductivity of the casing 12 can be achieved as described with respect to FIG. 1A. When the switch 10b is subjected to movement, the magnetic body 14 moves to the position with respect to the conductor 16a, as indicated by the dotted line, so that the conductor 16a comes into contact with the inner wall of the cylindrical casing 12. Complete the circuit with (16a, 16c).

In Fig. 1C, the motion sensing switch 10c is provided with two pairs of conductors, namely conductors 16a and 16b and conductors 16d and 16e. The permanent magnet 15 is located near the midpoint of the longitudinal axis of the elongated casing 12. Thus, when the motion detection switch is at rest, the magnetic body 14 is in the vicinity of the longitudinal intermediate point of the casing 12 in the magnetic field created by the permanent magnet 15. When the switch is in motion, the magnetic body 14 moves and comes into contact with the conductors 16a and 16b or the conductors 16d and 16e, as described with respect to the conductors 16a and 16b of FIG. 1A. According to the movement received by the motion detection switch, the magnetic body 14 alternately contacts the conductors 16a and 16b and the conductors 16d and 16c, thereby causing a flashing effect.

In FIG. 1D, the motion sensing switch 10d is shown in an end view, and the conductors 16f and 16g are disposed across the end of the casing 12a. The ring magnet 15 surrounds the conductor and the remote casing 12a. When the switch is in the resting state, the magnetic body 14 is located in the region of the casing 12a surrounded by the ring magnet 15. When the switch 10d is in motion, the magnetic body 14 moves from the region surrounded by the magnet 15 to contact the conductors 16f and 16g to complete the circuit.

In each of the embodiments shown in FIGS. 1A-1D, the conductor may be connected to a light source, such as a battery, a light bulb, or an LED, for example.

In the embodiment shown in Fig. 2, a motion detection switch 10a as shown in Fig. 1A is connected to both terminals of the battery 17 via the conductor 16a, and through the conductor 16b. 17) is connected to the negative terminal. The lamp 18 is connected to both terminals of the battery 17 via the conductor 19a, and is connected to the negative terminal of the battery 17 via the conductor 19b.

The nonconductive and nonmagnetic inner body 33 may be molded from materials known in the art, such as plastic, rubber, and the like. The conductor 32a is inserted through the port 38a and the port 38b across the through hole 34, as shown in FIGS. 4 and 5. A port 39 extends into the through hole 34 through the cylindrical outer portion 35 of the inner body 33, and the conductor 32a removes the groove 36 and the port 39 from the light source 31. Extends into the through hole 34.

In the nonmagnetic and conductive elongated casing 41 provided with the bore 42, the flange 43 and the window 44, the magnetic body 45 is arranged as shown in FIG. 5. A peg 40 is provided on the flange 43 of the casing 41, and a notch 40a is provided at an end of the inner body 33 away from the inclined plane, so that the conductor 32b and the window are provided. This allows you to align (44) correctly. Of course, the peg may be provided in the inner body, the notch may be provided in the flange. The non-magnetic and conductive elongated casing 41 may be molded from materials known in the art, such as copper, aluminum, brass and the like. Magnetic material 45 is typically molded from a steel material, such as a steel bearing. In order to improve the conductivity of the magnetic body 45, a coating of a metal such as copper, aluminum, or the like may be used.

A permanent magnet 46 surrounds the casing 41 under the window 44 and preferably contacts the flange 43. The permanent magnet 46 may be in contact with the narrow portion 47 of the through hole 34 provided in the inner body 33. The battery 48 is disposed inside the through hole 34 as shown in FIG. 5, and the negative terminal 49 is in contact with the flange 43 of the casing 41, and both terminals 51, that is, the battery 48. ) Is in contact with the end of the conductor 32a where the conductor 32a extends into the through hole 34.

The nonmagnetic protective outer body 52 preferably extends over the elongated inner body 33. The outer body 52 may be formed of a material that is durable enough to protect the conductors and other portions of the motion sensing switch contained in the inner body 33, such as nonmagnetic metal, plastic, and the like. It is preferable that the light transmitting end cap 53 is screwed to one end of the protective outer body 52. The connection between the outer body 52 and the end cap 53 is preferably provided with an O-shaped ring 54 for sealing means, providing attachment means for attaching motion detection safety light to the air valve stem of the bicycle wheel. It is good to provide the thread processing part 59 to the said end cap. The light transmitting end cap 53 may be molded from a material known in the art, such as plastic, and may be colored.

It is advisable to screw the end cap 56 to the other end of the protective outer body 52, the O-ring 56 provides a sealing means, and to the bore 58 of the end cap 55. The inserted spring 57 allows contact between the negative electrode 49 of the battery 48 and the flange 43 of the casing 41. The end cap 55 may be molded from any suitable material known in the art, such as, for example, non-magnetic metals, plastics, and the like.

By providing a ring-shaped magnet 46 around a cylindrical casing in which the magnetic field is made inside the casing 41, a substantially uniform magnetic field can be formed inside the casing 41. This substantially uniform magnetic field keeps the magnetic body 45 away from the conductor 32a and generally keeps the magnetic body suspended (ie floating) in the cylindrical casing. The magnetic attraction force of the magnetic body by the magnet is determined by the appropriate centrifugal force such as that generated when the motion detection safety light is attached to the moving wheel of the bicycle or the wheelchair, or the magnetic body 45 by the appropriate josling action or rotation. Sufficient to complete the circuit in contact with the inner wall of 41) to light the light source. If a motion sensing safety light is attached to the air valve stem of the bicycle wheel, the safety light is sufficient to provide ring-shaped light inside the wheel rim when the bicycle is moved at a sufficient speed. When the motion detection safety light returns to the idle state, the magnetic body returns to the magnetic field region, the circuit is disconnected and the light source is turned off.
