Horn device Cross-reference to related applications

This application claims US Application Serial No. 11/678,818 (applied on February 26, 2007, in the trial) and US Design Application Serial No. 29/249,441 (Application on November 6, 2006) The priority of each of them is incorporated herein by reference.

Field of invention

The present invention relates to a hand-held signaling device for use in remote signaling. In particular, the present invention relates to a portable electrical horn having improved security, portability, reliability, and enhanced power storage capabilities.

Background of the invention

Horns are widely used, including for sports, hunting and rescue work. Typically, horns are divided into two distinct types: gas horns and electrical sirens.

The operation of the hand-held gas horn device uses compressed gas released from a high pressure tank, which may be compressed air, butane, hydrofluororocarbon (HFC) 134 A gas (environmentally safe chlorofluorocarbon) , Freon as a HCFC refrigerant 22 and any other type of compressed gas combination (nitrogen, argon, etc.) (each of these conventional gases and gas compositions/mixtures are referred to as "gas (air or air)", as discussed later) .

This type of gas horn typically has an acoustically required horn-like fixture that, together with the actuator button and a tapered horn nozzle Operating, the gas horn is configured to produce a loud horn sound as the gas is released from the high pressure tank and through the horn fixture and released outwardly from the cone horn nozzle.

Handheld gas horns generally have limited capabilities because the size of the high pressure tank is critical to the portability of the horn. Due to the numerous mechanical components, the configuration of a gas horn device is quite complex, including the high pressure tank, horn nozzle and the required and related seals mentioned above, but it has historically been used to generate some A notice that one of the signals is loud.

In particular, conventional gas horn devices should be assembled to have excellent sealing characteristics to prevent leakage of compressed fluid through the outer casing of the device, suffer from functional loss, poisoning, contamination, and other damages mentioned below. . In addition, the unexpected loss of gas pressure causes a gas horn to lose its function, and a slow loss of pressure (through a slow leak) results in a decreasing audio output.

However, many conventional gas horn devices may not be satisfactory for leak prevention due to limitations in sealing technology. Therefore, the condensate formed during the use of the gas horn device (from the high pressure to the low pressure and the heat transfer from the liquid to the gas) may leak through the poorly sealed joint and burn to the user's hand, here The condensate is extremely cold or irritating to the skin.

A poorly sealed gas horn device has a further negative result regarding the user's hand, i.e., may become slippery during use of the device, which may negatively impact the user's grip on the device. In addition, when used at high altitudes, gas horn devices may be hazardous to health due to the expansion of the compressed fluid/propellant, which may minimize the effectiveness of the device and In the case of the end, it may cause a fire for the selected gas composition. Structural countermeasures against minimizing the above problems often result in an overly complex device structure that can be cost prohibitive.

Finally, for many conventional gases, an additional damage includes the problem of accidental poisoning or accidental oxygen substitution. For example, an accidental Freon 22 (monochlorodifluoromethane) poisoning case on a fishing boat has been reported (see February 18, 2006, Forensic Sci. Int., Kumamoto, Japan 860) -8556, 1-1-1, Honzen, Kumamoto University Medical Science Research Institute, Department of Forensic Medicine, Koreeda A.).

The electrical horn mitigates at least some of the problems associated with gas type horn devices. Typically, electrical horns conventionally use a vibrating diaphragm that is driven by an electromagnetic device. The current pulse is generated by a mechanical switch that responds to diaphragm motion, whereby the normally turned-on switch will excite a magnetic coil to cause the diaphragm to move in a direction relative to its elastic deviation. The movement of the diaphragm will in turn not turn the switch to allow the diaphragm to return to the other direction, thereby turning the switch on and causing the cycle to be repeated. The life of such horns is limited by the life of the power source used in the horn, which unfortunately may not be satisfactory. Similarly, the decibel (dB) range of a typical electrical horn is limited by an initial response of about 90 dB based on the low current level available from the self-contained battery system.

Accordingly, there is a need for a portable electrical horn that has an enhanced power storage capability with a simple structure that allows for convenient storage and easy replacement of power supplies with extended useful shelf life without Damage caused by leakage and it is used by all users (including Children and those who do not need special training are safe to operate without danger.

There is a further need for such a portable electrical horn to provide a clear indication of the end of the current power supply life and automatic switching between the current power source and a backup power source.

Summary of invention

These and other needs are met by a portable electrical horn that is assembled in accordance with the present disclosure. The disclosed electrical horn has an outer casing that is provided with two spaced apart compartments that are assembled to accommodate respective primary and backup power sources. Preferably, but not necessarily, a power source comprises a nickel cadmium (NiCad) battery or other form of battery that extends life or increases current strength. The presence of the backup power supply increases the life of the exposed horn, allowing the user to easily replace the main power source that is exhausted by the power supply in a time efficient and simple manner, without the result of continuous electrical connections. Exhaustion of the risk of storing power.

The disclosed horn housing preferably has a pistol configuration including an elongated handle and a housing extending laterally relative to the longitudinal axis of the elongated handle. The outer casing is preferably formed and has one of the battery storage compartments in the handle and the other compartment is in the casing. Thus, the enclosure encapsulates, protects, and provides for the installation of electronic, mechanical, and electrical components for the disclosed horn in a secure manner without the risk of damage during transportation and long term storage (eg, in emergency storage). .

Each of the battery containment compartments is positioned to provide a simple access for the user. Preferably, the compartment provided in the handle of the outer casing leads to the handle The bottom of the handle, while the other compartment is positioned adjacent the proximal end of the housing. Both compartments are closed by respective shutters that are detachably mounted to the housing and that are easily handled by the user and are sufficient to withstand moisture during long term storage or severe use.

The compartments are inconsistently assembled, and each shape and size allows a battery to be properly routed to a storage/operating position. The doors can be provided with respective locking or spring-locking mechanisms to securely secure the batteries within the respective compartments while allowing the user to easily open the doors to insert the batteries into the compartment The cells are removed from or from the compartments.

While alternative operational circuitry may be provided without departing from the scope and spirit of the present invention, a preferred design provides an electronic driver for the disclosed horn to supply short current pulses to an electrical sound producing device. The driver is configured to have an oscillator that provides a series of pulses for use by an electromagnet that attracts a ferromagnetic diaphragm. The pulses have a repetition rate that is substantially less than the natural frequency (3000 Hz) of the diaphragm. For each pulse, the electromagnet attracts and then releases the diaphragm to allow it to vibrate for several cycles before applying another pulse. It is further proposed that a feedback circuit that responds to the diaphragm position causes the pulse timing to be slaved to the diaphragm frequency to ensure efficient coupling. This arrangement is preferably adapted for high frequency horns (100 dB or higher) that have relatively small diaphragm motion and easily continue to vibrate when the input pulse is removed, but are not limited to any particular type of dB range. Or frequency.

In order to effectively operate the first horn, it is recommended to couple the electrical energy to the system in a manner that best utilizes the energy that has been given to the diaphragm assembly. In the part. The synchronization of the input pulse and diaphragm motion is of great importance in achieving the highest acoustic energy output for a given electrical power input. In accordance with this alternative aspect of the present disclosure, the disclosure horn has a central processing unit (CPU) that performs operations to provide the desired synchronized software, although it will be recognized that aspects of the present invention may be implemented by various electronic modes of operation. The circuits operate without departing from the scope and spirit of the invention.

In a further aspect of the disclosure, the software executable by the CPU is operable to monitor the operation of a currently operating battery, and when the resources of the current working battery have been exhausted or may be determined in the near future A backup battery is activated when the degraded point is about to be exhausted (in normal use or at elevated or lowered temperatures).

In addition, it will be appreciated that the present invention can also be provided with a simple electrical circuit that does not have a central processing unit (CPU) whereby a trigger is simply activated to complete a battery power source and the sound producing loudspeaker An electrical circuit between. It is envisioned that while any embodiment is suitable under certain manufacturing or user conditions, a particular configuration would be preferred under a selected condition. For example, when low cost is critical, no CPU is included, or otherwise, a control CPU can be optionally included when delicate power and sound management are critical; all without departing from the scope and spirit of the present invention.

In accordance with a further aspect of the present disclosure, a device for conveniently hanging the horn on a user includes a strap attached at one end to the user's clothing. The other end of the strap is detachably coupled to the horn housing to allow the user to unlock the horn when the user's position requires such an action. In alternative variations, it should be recognized that the above cable can be It is a change in the tightening cable, the lasso, the belt clip or the shoulder strap attachment without departing from the scope and spirit of the invention.

Detailed description of the preferred embodiment

Reference will now be made in detail to the preferred embodiments of the claims Wherever possible, the same or similar reference numerals are used in the drawings and the description The drawings are in simplified form and not in precise scale. For the sake of convenience and clarity, directional terms such as top, bottom, up, down, over, above, and below may be relevant. The It is used as a graphic. These and similar directional terms are not to be construed as limiting the scope of the invention in any way. The words "attached," "connected," "coupled," and similar terms, with the morpheme, are not necessarily intended to mean a direct and a contiguous connection, but also include an intermediate element or device. Mechanical and electrical connections.

Figure 1 illustrates one of several applications using an electrical horn 10, for example, in this example, for sending an emergency signal to a hunter who is lost in the forest. Additionally, it will be appreciated that the horn 10 can be easily planned and also used to provide a pre-recorded digital sound to seduce it, for example, by mimicking the sound of a wild turkey. Therefore, the horn 10 should be considered for both emergency and sports purposes. In non-emergency sports activities (here hunting), a user 100 uses the horn 10 to produce an acoustic signal that is generally similar to the frequency and pitch of the wild turkey. However, the horn 10 can be used during athletic activities, rescue operations, and many other operations that require different acoustic signals.

Referring to Figure 2, the horn 10 is assembled to have a housing 12 having a handle 14 and a housing 16 that extend laterally to each other. The outer casing 12 can have a wide variety of shapes and sizes, which are associated with the characteristics of a particular horn application, and are not limited to the general T-shaped cross-section illustrated in FIG. Preferably, the outer casing 12 is formed as a two-piece unit comprising half blocks 11 and 13 centered on a longitudinal axis A-A and by any conventional fastener means 15 ( Including, for example, screws, bolts, and pins are detachably coupled to each other.

The coupling halves 11 and 13 are realized whereby the entire outer casing is substantially waterproof, allowing the horn 10 to be effectively used even under adverse weather conditions (moisture, moisture, ice, etc.). Each of the half blocks 11, 13 includes a respective handle 14 and the cover 16 part. However, it is contemplated that the outer casing 12 can be formed as a single body. Thus, the outer casing 12 is made of lightweight plastic and, due to its configuration and material selection, the outer casing 12 is characterized according to the degree of robustness selected by the manufacturer or consumer. The molding technique is not the only manufacturing possibility to manufacture the outer casing 12, and it can be easily replaced by any other suitable technique without departing from the scope of the invention.

The handle 14 is ergonomically assembled to provide a comfortable grip to the user 100 and can have a structured surface 18 that prevents undesired movement of the user's hands and horns 10 relative to one another. Preferably, the handle 14 is assembled to allow the entire length of the user's hand to rest on the handle 14, and the finger rests on a push button trigger 22 that is operable to respond to the user's The horn 10 is activated by the pressure applied by the push button 22. As illustrated in the figures, the casing 16 has a generally funnel-shaped body having an end 20 at the edge of the body of the casing. In a related design, the casing 16 is optionally assembled to act to concentrate the sound in a given direction, although in the case where a loudspeaker assembly (slightly mentioned) is preferably located in the open face This does not need to be.

In accordance with one of the many notable features of horn 10, housing 16 and handle 14 are provided with individual devices III and IV for receiving and storing power. Each storage device includes a compartment that is configured to receive and store a battery, as will be explained below. Also, each compartment may be removably and selectively connectable to a control electrical circuit, or both compartments may be connected in series, and ultimately only one compartment may be connected such that the unconnected compartment is allowed Store only one battery (power supply).

The horn 10 can be conveniently hung on the clothes worn by the user. For example, a strap assembly 24 can include an elastic band with one end of the two ends coupled to the garment and the other end 26 provided with a loop. A spring lock fitting has a bracket operable to securely engage the loop end 26 of the elastic band, and a snap lock 28 attached to the bracket. The spring lock 28 is operable to have an open position and a closed position in which a safety ring 30 passes through the outer side of the spring lock 28 in response to an external force applied by the user to a spring lock actuator. In the closed position, after the external force is stopped, the safety ring 30 and the spring lock 28 are reliably engaged with each other. The safety ring 30 is also operable to assume an open position to pass through a flange 32 formed on the outer casing 12. For example, the flange 32 can be provided at the bottom of the handle 14, although other locations that are configured to couple the safety ring 30 and the outer casing 12 are contemplated within the scope of the present invention. The flange 32 has a through opening that is configured to allow the body of the safety ring 30 to freely hang over the flange 32, whereby the safety ring 30 can be rotated or rotated relative to the flange 32 in the suspended position of the ring.

Figure 3 illustrates a selectable central processing unit (CPU) 44 (as disclosed below) that is configured to receive and store the interior of the housing 12 of the plurality of power supplies 36 and 40, operable to control the performance of the horn 10. A sound generating unit, generally indicated at 42, and a wire 34 that couples all of the elements together. The plurality of power supplies 36 and 40 can be individually assembled, preferably a typical DC-9V battery. The batteries 36 and 40 are preferably housed in respective compartments III and IV formed in the handle 14 and the casing 16, as will be explained below. As mentioned above, the present invention can be retrofitted to operate with or without the central processing unit 44, depending on the manufacturer or user. Expectation depends. For example, in the case where reduced cost and circuit simplification are desired, a simple hard-wired (CPU-free) circuit can be provided, as will be appreciated by those of ordinary skill in the art of consumer product electrical design. As an alternative example, in the event that a CPU system is desired, for example, to simultaneously or continuously use two power sources to manage sound, signal or power output, a CPU system can be configured to achieve this goal.

The sound generating unit 42 (amplifier) generally has an elastic diaphragm (generally made of spring steel or a rigid plastic or Mylar) and a coil forming an electromagnet. As is well known, the horn 10 acts in a manner known to those of ordinary skill in the horn field and is generally based on Hooke's law, which states: "Assume that the spring is not exceeded (here is the loudspeaker diaphragm) The elongation is directly proportional to the applied load". If properly designed, the elastic diaphragm continuously oscillates back and forth as long as current is applied. The rapid vibration of the diaphragm removes the gas and produces an output wave of the sound. The horn produces a constant variety of tones or frequencies, and a CPU hydroxy 44 (containing a pre-recorded signal) can be used to reproduce previously recorded signals, such as animal sounds, alarm signals, and the like. The pitch of the first horn is determined by the elasticity of the diaphragm, its physical size, the power of the electromagnet, the mass of the diaphragm, the mechanical arrangement of the switch contacts, the size and shape of the horn's outer casing, and some other contributing factors. As is readily understood by those of ordinary skill in the electrical and audio arts, the frequency can be easily adjusted to produce the desired sound. A software executable by the CPU 44 is operable to change the sound in accordance with the user's selection, which can be accomplished by an indicator 72 that is schematically shown in FIG. 3 and coupled to the CPU 44. . For example, the sound produced by the horn 10 can be Choose from, but not limited to, the sounds of selected animals in the group of animals: hens, bulls, horses, sheep, cocks, frogs, dogs, ducks, cats, wild turkeys. Similarly, the duration and rate at which the sound is produced can be adjusted by the software executable by the CPU 44.

Referring to Figure 4, a bottom portion 46 of the handle 14 has a compartment III that is assembled to receive a battery 36 that can be slid into the compartment III to a mounting position in which a spacer 47 The electrodes of the battery are reliably joined. To reliably secure the battery 36 in the installed position, a shutter 48 is assembled to releasably close the opening of the compartment III and hold the battery within the compartment. After manually inserting the battery 36, the shutter 48 is juxtaposed with the opening of the compartment III and then pushed therein, whereby the outer surface of the door and the bottom of the handle when the door 48 reaches its closed position 46 The outer surface is flush. The body of the shutter 48 has a window 50 provided with a bias locking unit 52 that is assembled to have a curved end or inner end that resiliently opposes the inside surface of the compartment III. Accordingly, the shutter 48 is frictionally engaged with the handle 14, and can be disengaged after application of an external pulling force sufficient to overcome the friction generated by the end of the locking unit 52 to remove the door 48 from the compartment III. In order to prevent the door 48 from being uncontrollably displaced into the compartment III, the latter has a stop surface 49 that abuts and extends in a closed position to one of the surfaces 51 of the door 48 in the closed position of the door. Preferably, but not necessarily, the battery 36 mounted to the handle 14 is a main power source.

Turning to Figure 5, the compartment IV is provided in a proximal end 54 of the casing 16 and is assembled to accommodate the backup battery 40. The opening of the compartment IV cuts into one of the opposite edges of the casing 16 and terminates at a distance from the other end. When the battery Upon being slid into the compartment IV to its desired mounting position, a door 56 closes the opening and secures the battery in the desired position. The door 56 has a generally U-shaped cross section including a central bottom portion 64 that is provided with an interior surface that abuts the opposing surface of the battery 40 in the closed position of the door. The two angled sides 66 and 68 are adjacent the central portion 64 and have respective coplanar inner surfaces offset from the inner surface of the central portion 64, whereby when the shutter 56 closes the opening of the compartment IV, The outer surfaces of the sides 66 and 68 are flush with the outer surface of the casing 16 and the central portion 64 is concave. The desired closed position of the shutter 56 is further recessed through the bottom plate of the compartment IV and assembled to slidably receive a fin provided on the inner surface of the side surface 68 and extending beyond the side surface 68 (for clarity) The purpose of the guide channel 70 is not shown, but is well understood by those skilled in the art. During installation of the shutter 56, initially, it is slightly tilted such that an arm 62 provided on the inner surface of the side 66 abuts against the floor of the compartment. Next, the shutter 56 is substantially parallel to the longitudinal axis of the opening of the compartment IV such that the fin is received in the channel 70. Further, the shutter 56 is pushed inward to achieve the desired closed position. In order to secure the shutter 56 in the desired closed position, it has a locking unit 58 that is similar to the locking unit 52 (Fig. 4) of the shutter 48. Thus, in the desired closed position of the shutter 56, one of the inner ends 60 of the locking unit 58 is resiliently biased relative to the opposing surface of the compartment IV. To open the shutter 56, an external force can be applied to the locking unit 58 to pull it with a force sufficient to overcome the biasing force of the inner surface 60 of the locking unit 58 relative to the inner surface of the casing 16.

In a practical operation of the alternative example, the user presses the switch 22 (the first 3)), which can be assembled by a push button or a toggle switch, and the electrical contact allows current to flow to a relay, which in turn provides current to the horn of the horn, which attracts the sound generating unit 42. The diaphragm. Thus, the diaphragm shrinks to its mechanical limit and out of the contact, which stops the flow of current to the electromagnet. The diaphragm is released to return to the previously neutral position, turning the switch on again and thereby pulling the diaphragm back to establish a uniform oscillation.

In addition to FIG. 3, referring also to FIG. 6, during step 80, in response to the start switch 22 (FIG. 3), the software executable by the CPU 44 that is optionally included may determine the power/lifetime state of the currently operating battery. For example, battery 36 (Fig. 4), as illustrated in step 82. Among various monitoring techniques, CPU 44 may, for example, include software for tracking and storing the actual life of the battery (i.e., the time at which the battery has actually provided power to horn 10). If the stored reference value has been reached, the software executable by the CPU 44 can automatically switch the battery 36 to the battery 40 (Fig. 5). Those of ordinary skill in the art will readily recognize a simple battery switching circuit that is activated by CPU 44 in response to a signal indicating that the resources of battery 36 have been used up or are about to be exhausted. Having determined that the battery 36 is to be replaced, the backup battery 40 is activated by the software executable by the CPU 44, as illustrated in step 86.

The horn 10 can be operated under different climatic conditions. One of the important climatic conditions that can seriously affect the useful life of a battery is temperature. If the horn 10 is used at normal temperature, as indicated by step 90, the batteries 36 and 40 will generally operate longer than at elevated temperatures. For example, the CPU 44 can execute a software that not only operates to track the actual operating time of the battery, but also the ambient temperature. If the battery is operated under adverse weather conditions, as indicated in step 94 As shown, the software can adjust the expected actual life of the battery, and if the temperature has been detected above a certain reference value for a predetermined period of time, the life should be shortened.

Having ensured that the horn 10 is properly powered, the software executed by the CPU 44 can further adjust the pitch, frequency and/or duration of an acoustic signal as selected by the user, as illustrated in step 84. Finally, when the horn 10 is ready for operation, the software executed by the CPU 44 activates the sound generating unit 42 to produce the desired sound.

It is of course easy for those with ordinary knowledge in electrical engineering to understand that the actual life of the battery can be monitored in various ways. Additionally, or the user can always manually switch the batteries by operating a manual switch. Additionally, only one compartment III and IV (Fig. 2) can be assembled to provide an electrical connection between the battery and the remaining components of the horn. In this case, the user will have to manually replace a waste battery and will be re-guaranteed that the non-use/storage battery will include the remaining power for emergency use. Although the horn 10 is preferably made of plastic, other materials, such as metal, can be successfully used.

In addition, it should be appreciated that the power source 36 can be used interchangeably as a rechargeable power source that can be removably retained in the body 14 or can be fixedly coupled thereto without departing from the scope and spirit of the present invention. . Where the manufacturer uses an option that includes a rechargeable battery/power source, it will be appreciated that the horn 10 can be equipped with recharging mechanisms of the type that are known to those of ordinary skill in the art of rechargeable consumer electronics.

In the context of the patent application, a device or a step plus functional term is intended to cover the structure described or suggested herein as performing the recited functions, and not only It is a structural equivalent but an equivalent structure. Thus, for example, although a nail, a screw, and a bolt may not be structural equivalents, since a nail relies on the friction between a wooden portion and a cylindrical surface, the helical surface of a screw positively joins the wooden portion. And a bolt head and nut are pressed against opposite sides of a wooden portion, and in the environment of fastening the wooden portion, a nail, a screw and a bolt can be easily understood by those of ordinary skill in the art to be equivalent structures.

The specific features described herein may be used in some embodiments and not in other embodiments, without departing from the spirit and scope of the invention.
