Description

Rebound device for child climbing window

Technical Field

The invention relates to an appliance for preventing children from casualty, in particular to an appliance for preventing children from climbing a window to cause injury.

Background

The children are curious and vivid in nature, have the desire of no suppressible exploration on unknown things, and have great attraction to the unknown things in the world outside the window, so as long as parents neglect, the parents can climb up the window, and most parents climb out uncontrollably, so that irreparable loss is caused. At this time, if the child can reversely push the child when climbing the window, tragedy can be avoided. Sometimes the captain is not at the right side at this time, or is found to be a distance from the toddler, sometimes only a tragedy of looking at the eyes open occurs. If this is done with an implement mounted on the window, the child is forced in a timely reverse direction when he steps out of this dangerous step, and the child may not say something is going to fall, but something tragic is avoided. According to the idea, an appliance for enabling the child to climb the window to rebound can be designed.

The DC linear motor is an advanced technology, and a coil in a magnetic field can freely move along an iron rod. In the stroke range of the coil, the permanent magnet gives a substantially uniform magnetic field B, and when direct current I is introduced into the coil, the part of the conductor coil in the magnetic field is acted on by electromagnetic force. The direction of this electromagnetic force may be determined by the electromagnetic induction left hand rule. According to the ampere rule, the magnitude of the electromagnetic force can be calculated by the following formula:

BIL B is the magnetic induction T (tesla), I is the current intensity a (amperes) in the conductor, and L is the length M (meters) of the conductor in the magnetic field. As long as the electromagnetic force applied to the coil is larger than the static friction force FS existing on the coil support, the coil can generate linear motion. This is the operating principle of a linear dc motor. This principle and apparatus can provide a straight thrust.

The switch of the hook switch in the telephone has the function of connecting different circuits when the switch is pressed or not, for example, the ringing circuit can be connected when the telephone is hung up, and the communication circuit can be disconnected when the telephone is off-hook. When a child presses on the electric switch, the connection direction of the circuit can be changed, and the electric switch is suitable for changing the circuit when the child presses on the electric switch.

The astable circuit (self-excited multivibrator) in the electronic switch circuit can emit oscillating waves with different frequencies, and if a buzzer is connected, the electronic switch circuit can play a role in alarming.

The device can be combined into an appliance which can prevent children from climbing the window to cause casualty by properly combining the components of a power supply, two fork spring switches, a self-excited multivibrator, a buzzer and two self-designed direct current linear motors. It excels in saving life, shan Da .

Disclosure of Invention

In order to achieve the above-mentioned idea and the above-mentioned object of composing a 'child climbing window rebounder' with the related elements, the structure and composition thereof will be described in detail. The product is composed of two major parts respectively. One is a 'trigger', and the other is a 'rebounder'. The two parts are combined together, and when a child touches the trigger by pressure, the child is rebounded by the rebounding device at the same time.

The 'trigger' is a rectangular frame whose length is slightly longer than 1/2 of the length of a set of aluminum alloy sliding windows (because a set of two aluminum alloy sliding windows always only opens one). A long wood board is embedded in the rectangular frame to form a frame, and the height of the frame is equal to that of the rebound device. The upper surface, the left side and the right side of the wood board are respectively provided with a fork spring switch, a compressible spring is fixed at the equal distance between the fork spring switches, the spring is slightly higher than the fork spring switches, and when pressure is applied, the spring can drive the press plate to press the fork spring switches. The reverse side of the wood board is provided with a wiring of two groups of cross springs, and two output wires of a group of cross spring switches are connected with the 'multivibrator' and the 'buzzer'. The other set of cross spring switches has two output lines jumping out of the 'trigger' into the 'rebounder'. And each input end of the two groups of fork spring switches is respectively connected with the positive pole and the negative pole of the input direct-current power supply 12V. The press plate of the trigger is a strip-shaped wood plate, is tightly connected with the upper end of the spring reversely, is slightly higher than the pressable part of the fork spring switch, is arranged right above the fork spring switch, and is provided with a bulge at the opposite position of the reverse side of the press plate respectively, so that the fork spring switch can be just pressed when the press plate is pressed, and the fork spring switch can not be touched at ordinary times. The pressing plate is slightly higher than the whole body, so that the pressing plate is certainly contacted when the child climbs the window.

The ' rebounder ' is a frame with a bottom, the length of the rebounder ' is as long as that of the ' trigger ', the bottom plate is divided into two ends, two iron sheets with a short iron cylinder at the center are fixedly arranged on the bottom plate, and the iron sheets are adsorbed with the circular rings of the permanent magnets to form two powerful magnetic fields. Winding two coils, the skeleton of which can freely slide on a short round iron column in a magnetic field, installing a long rebound plate on the top of a wooden frame, the rebound plate is slightly shorter than the length of the frame so as not to influence the ejection, and the coil frame is fixed on the rebound plate, when the coil is electrified, the whole coil frame is acted by ampere force, and when the coil is ejected outwards along the round iron column, the whole rebound plate is collided with the body of a young child (equivalent to providing a thrust for the young child). Because the coil of the direct current linear motor must have the leading-out wire, and the pop-up distance is very long when the elasticity is large, so that the longer leading-out wire is needed, the framework of the coil is connected with the rebound board, a certain length must be firstly kept on the rebound board, then the positive and negative currents connected on the fork spring switch are connected through the contact point on the rebound board, and the rebound device can normally work.

The power supply is the foundation of the product and provides the thrust of the rebounder, when the magnetic field intensity and the coil (the length of the conducting wire) are fixed, the ampere force is related to the current, so that a direct current power supply with low voltage and large current is selected, therefore, the voltage of the power supply is not more than 12V, and the larger the current is, the better the direct current power supply of the transformer is.

Two small independent copper sheets are fixed on the reverse side of a trigger-mounted cross spring switch wood board and are respectively used as the connection points of positive and negative incoming wires, two groups of cross spring switches are positive, negative first connection points are respectively connected to the positive and negative electrodes, and two second connection points of one cross spring are respectively connected to the positive and negative electrodes of a self-excited multivibrator. The trigger of the other fork spring switch with two second contacts jumping out is connected with the rebounder through wiring, and is respectively connected with one end of the coil in parallel to form a complete current path of the whole appliance.
