It is activated by moving a switch mechanism called a switch in the axial direction. This invention relates to a switch for a portable light source.

A button that opens and closes an electrical circuit between a light bulb and a source of electrical energy (usually a battery) Flashlights and other portable light sources with tongue switches are well known.

It is particularly important that such switches be robust and reliable. because , the design of most portable light sources does not allow the bulb to emit light if the switch fails. This is because it is impossible. Switch failure is common in these devices. This is one of the problems encountered in Generally, a switch failure is caused by a mechanical failure of the switch mechanism. or failure of the electrical contacts of the switch to make a proper connection. arises from In addition to being rugged and reliable, switches are relatively simple and inexpensive. It should be constructed from well-designed components that are easy to assemble and economically manufactured. stomach. These features cannot be obtained with conventional push-button switches for portable light sources. .

Another concern in the design of portable light sources is that the switch may act unexpectedly when not desired. This is to prevent electrical circuits from being connected. handheld portable light In the case of a typical flashlight, the switch is generally connected to the handle (in the case of a typical flashlight, the switch is The holding part is located on the body of the flashlight or the battery compartment), and the user That I! You can conveniently operate the switch with your thumb while holding the grip with your palm. It is now possible to To reduce the risk of the switch tripping unexpectedly, Place the switch in the retracted position of the grip so that the button is clear from the surface of the grip. It can be prevented from protruding too much.

However, for other types of portable light sources, a pushbutton switch is preferred. or in a position that is impractical for pressing the switch. this For example, if a flashlight is placed inside its tail cap. This is the case when the device is equipped with a pushbutton switch. Flash lights like this In this case, the user grasps the body of the flashlight with the palm of his hand and slides his thumb over the edge of the body. It is designed to extend and push the tail cap switch in the axial direction. This structure With this thumb angle, you cannot easily press down on the recessed switch. Therefore, the button should not be placed beyond the end of the body. It is easy for the switch to turn on and off unexpectedly, so it is difficult to solve this problem. There is a need for a switch of this type that can be turned off and is easy to operate.

Highlights 91 uniforms According to the present invention, a switch for portable light sources is provided that is robust, reliable, and easy to assemble. A first assembly is provided.

The camf The follower face 166 is preferably inclined at 45° relative to the central axis of the switch; The full lug 152 of the plunger 120, which is the locking partner of the cam follower surface 166, It follows the secondary cam surface. The secondary cam follower surface 166 has a corresponding There is a part of the dark area between the cam follower surface and the gap. However, the guide sleeve 14 0 guide surface and the half lug 164, each half lug 16 4, the complementary part (i.e. the other half of the full lag) has been omitted. dark part 16 0, the trough 162 and the half flag 164 form a contact support surface 168 extending laterally. (line surface 168 supports base 170 of metal contact 172) .

The contact 172 connects the coil spring 72 and the retainer 74 (and therefore the switch body 56). Connect electrically and switch on the flashlight. The contact 172 is The base 170 of the contact 172 is passed around the cylindrical contact support 176 of the motor 130. An opening 174 is provided for the purpose. Preferably, contact 172 has four resilient leaves. 178, which improves electrical contact ability and also has a self-aligning function. have. Each leaf portion 178 has a rectangular cross-sectional shape and has a contact point. 172 and radially outwardly from the base 170 of the flashlight. It extends axially towards the minute. Each leaf 178 is oriented toward the central axis of the switch. Once bent inward, the rectangular end of each leaf 178 contacts the switch body. I try not to. Preferably, only the middle portion of each leaf 178 is switched. to come into contact with any other part of the body. Also, the contact is between the middle part of each leaf. Preferably, this is done at two points (ie at the side edges). This makes the electricity Adds integrity to the gas contact and increases the self-wiping action of linear and rotating contacts. Ru.

A coil spring 72 is supported by the base 170 of the contact 172 and extends forward relative to the battery. , and a rearward pressing force to the rotor and plunger. Also , the coil spring 72 functions to provide electrical contact between the battery electrode and the contact 172. It also has

Preferably, coil spring 72 comprises a dual diameter/double bift spring (FIG. 13). , the space between the base 170 of the contact 172 and the bushing 76 is formed to have a large diameter and a large pitch; The portion extending from the bushing 76 and making contact with the battery is formed to have a small diameter and small pitch. Large diameter portion provides stronger electrical contact between spring 72 and contact 172 and The ring 78 of the bush 76 comes into contact with the bush 76, the contact 172 and the rotor 130. form a shelf that provides the required amount of tensile force to the

The coil spring 72 also connects to the contact 172 and the buffer (M-plane member) of the rotor 130. This results in differences in the amount of compression in the small diameter section between different battery sizes. However, depending on the amount of compression in the large diameter portion between the bushing 76 and the contact point 172 in the rotor 130, Doesn't have a big impact. The center of the spring relative to the switch is fixed and therefore the battery so that the compression caused by If this were done, a single diameter spring would work well.

When the flashlight switch is in the "off" position, 120 and A portion of the rotor 130, all of the contacts 172, and a portion of the coil spring 72 are attached to the guide slide. It is now fitted into the tube 140. Plunge mid and low with 4 lugs If a sector is used, the guide sleeve 140 also has four sectors. Each section Since the sector is the same as the other three sectors, in the following we will refer to one sector. I will only explain. Each sector is spaced approximately 90” apart and and extends axially toward each end of the sleeve 140. Guide sleeve 1 40 has the following three areas in the axial direction, namely the plunge +120 in the axial direction. A lock area 180 (FIG. 13) that locks the rotor 130 so that it does not move. An intermediate rotor control gj that controls the axial movement and rotation of (and thus contact 172) region 182 and the entire contact 172 within the plastic guide sleeve 140. separated into a contact area 184 for holding (and thus maintaining an open circuit). Ru. Each sector has a support surface that guides the lugs on the plunger 120 and rotor 130. A boss 186 is provided. This support surface acts on the negative cam surface 150. The contact area 184 extends from the proximal end of the guide sleeve 140 to the contact area 184. Groove 188 guides axial movement of plunger 20 through full lug 152. Ru. The lug 152 of the plunger 120 is approximately in contact with the base of the guide sleeve 140. It is possible to move up to point area 184. The lock area 180 has a pocket 190. We are prepared. Inside this pocket 190, the full lug 152 of the plunger 120 is rotation from a first angular position within groove 188 to a second angular position within pocket 190; , which causes the cusp of lug 152 to align directly with a portion of boss 186 .

When the plunger 120 is in this position, the forward axial direction of the plunger 120 Movement is prevented by boss 186.

One side of the boss 186 forming the groove 188 has a rearwardly inclined half lug support. It terminates in surface 191. This half lug support surface 191 is the half lug support surface 191 of the rotor 130. Ability to guide flag 164 into a recess that places the flashlight in the "on" position have.

This position is defined by a trough 192 in the guide surface. Opposite side of valley 192 The surface is formed by an axially oriented support surface 194. This support surface 194 has , the half flag 164 rests when the rotor 130 is in the "on" position. Also, The support surface 194 supports the half lug 164 when pushed by the plunger 120. It has the function of guiding upward. The support surface 194 has a second slope for an "off" position. It terminates in a support surface 196. This second inclined support surface 196 is connected to the half flag 164. to the next groove 188.

The inclined support surface (half flag support surface) 191 corresponding to the "on" position is the second inclined support surface. The rotor 130 is longer than the bearing surface 196, so that the rotor 130 remains in the dark area of 120 during the plunge. The dark portion 160 of the rotor 130 rotates further with respect to the It can be advanced far enough to pass the cusp.

Switch body 56 is preferably formed from a conductive material such as aluminum. , 0-rings can be standard products, such as button buttons, button locks, plunge rings, etc. Preferably, the carrier, rotor and guide sleeve are made of plastic. Bush 76 Preferably, it is also made of plastic. The coil spring 72 and the contact 172 can be constructed by a person skilled in the art. Made of metals known to Used for the remaining parts that make up the flashlight Materials that can be used are well known to those skilled in the art, and material selection is determined based on end use, etc. Melt.

Next, assembly of the switch will be explained. First, guide it into the switch body 56. Position sleeve 140 and align ribs 142 with corresponding grooves 144 in switch body 56. Align. The rib 142 of the guide sleeve 140 allows the plunger 120 to Initial alignment of switch body 56 with tongue 70 is made. In addition, due to the rib 142 , rotation of the guide sleeve 140 within the switch body 56 is prevented. Next, Pass the full lug 152 of the plunger 120 along the groove 188 of the idle sleeve 140. and connect the link body 122 of the plunger 120 to the small diameter bore 1 of the switch body 56. 32 into the guide sleeve 140. . The link body 122 has grooves 134 on its outer surface that engage the sides of the rectangular opening 102. The bore of the button 68 is pressed inward until it inserted within. Next, seat the button cap 88 on the button 68. When aligned, the locking ridge on the insertion post 118 of the cap 8 will be inserted into the plunger. It engages a slot 138 in the wall of U-shaped groove 137 (FIG. 6) of carrier 120. Once you do that When the button 68 is locked into the plunger 120, it destroys one or more parts. It is not possible to disassemble plunger 120 and button 68 without This may result in the loss of one or more parts due to inadvertent disassembly of the switch. It never goes away.

Next, rotor 130 and contacts 172 are inserted into the open end of switch body 56. child This causes the cylindrical portion 158 of the rotor 130 to fit within the bore 148 of the plunger 120. will be placed in The plunger 120 has a full lug 152 that is connected to the guide sleeve 120. 0 within the guide sleeve 140 such that it is located within the corresponding groove 188 of the Directed. The diameter of the cylinder (cylindrical portion) 158 of the rotor 130 is 1. The contact Because it is larger than the diameter of point support 176, rotor 130 may be inadvertently damaged during assembly. The half lug 164 of the rotor 130 would not be placed in the opposite direction. Because it falls into either the groove 188 or the trough 192 of the guide sleeve 140, the The positioning of data 130 is not critical. Next, the cylindrical contact of the rotor 130 is The coil spring 72 is attached to the point support 176, and the rubber bush is attached to the coil spring 72. placed on the small diameter part of the Next, tighten the female screw provided in the bore of the switch body 56. The retainer 74 is screwed onto the end of the switch body 56 through the retainer 74. Dimensions of retainer 74 In this case, the end adjacent to the guide sleeve 140 is connected to the opposite end of the guide sleeve 140. The inner diameter of the guide sleeve 140 is equal to or greater than the inner diameter of the retainer 74. The leaf portion 178 of the contact 172 is smaller than the guide sleeve 140. as it transitions from the contact area 184 of the retainer 74 to the internal bore of the retainer 74. 178 is defined so that it can be easily moved. Do not screw retainer 74 completely. When seated together, preferably, the lower surface of the wrench gripping flat portion of the retainer 74 and the A gap is left between the end of the switch body 56 and the end of the switch body 56. Bush 76 is When the coil camp 46 (Fig. 1) is screwed on, the coil spring 72 is supported laterally. Ru. Further, the bush 76 is attached to the retainer 74 to the extent that it can come out of the retainer 74. 74. The coil spring 72 is pushed by the battery. When pressed, the bushing 76 also moves slightly with the battery. During final assembly, switch The tip is screwed onto the body 32 and is in the state shown in FIG.

The flashlight 30 of the above embodiment is particularly suitable for one-handed operation. Hula The body 32 of the flash light 30 holds the push button 68 between the thumb and index finger. Grasp so that it can be rotated from the locked position to the unlocked position (and vice versa) be able to.

The flashlight 30 is activated by pressing the button 68 with your thumb or any finger. It can be easily lit by adding .

Next, the operation of the switch will be explained. The power of the battery 34 directly adjacent to the switch A complete circuit exists between the pole and the end of the barrel 32 to which the tail cap 46 is threaded. It is assumed that the This circuit can be configured in any desired form. Also, Characteristics of the electrical connections between the switch and the battery and between the switch and the circuitry within the shell 32 The specific form can also be configured arbitrarily. Considering the illustrated embodiment, FIG. and FIG. 17 show the switches in the locked and unlocked positions, respectively. is shown. The flashlight 30 is in the off state, and the contact 172 is contained entirely within guide sleeve 140. 120 during plunge (according to The corresponding full lug 152) is moved from the first position in FIG. 17 to the second position in FIG. rotated into position. Each cusp has a corresponding pocket 19 in the guide sleeve 140. 0 and thus prevents axial movement from right to left as viewed in FIG. Ru. In this state, the tongue 70 of the switch body 56 is attached to the cap of the button 68. The bushings are placed directly opposite the corresponding shelves 114 in the tray 96. It will be appreciated that the lens 68 has also been rotated to an angular position. Stopping surface 116 (No. 9) and the side of the pocket (Fig. 3), the button 68 and plunger Further rotation of the carrier I20 is prevented. Also, in this state, the plug The primary cam surface 150 of the plunger 120 is connected to the corresponding primary cam follower of the rotor 130. (compare Figures 16 and 17). these two aspects are adjacent to each other, rotate the plunger 120 to the position shown in FIG. Returning is easily done. In addition, the shank on the secondary cam surface 154 of the full lug 152 - Movement of the cusp of the flag 164 is also facilitated. Furthermore, the half flag 164 The movement is caused by the return downward movement through the cusp of Lulug 152 to the position shown in FIG. There will be an audible "click" sound indicating that the process is complete. “Click” like this This audible sound occurs when the plunger 120 is rotated in the opposite direction for the same reason. occurs.

In the state shown in FIGS. 16 and 17, the rotor 130 is at its lowest position of equilibrium. , the plunger 120 is not expanded, and the large diameter portion of the coil spring 72 is at its maximum. It is in a stretched state. Additionally, each of the four leaves 178 of the contact 172 has a guide slide. It is in contact with the inner plastic surface of the tube 140.

To turn on the flashlight 30, press the button 68 and press the button. Push the plunger 120 axially forward toward the flashlight battery 34. Ru. This causes the O-ring 126 of the plunger 120 to It slides within the diameter bore 132. Primary cam surface 150 and secondary cam of plunger 120 Surface 154 corresponds to the corresponding primary cam follower surface and secondary cam follower surface of rotor 130. It engages surface 166 and pushes rotor 130 against the opposing force of coil spring 72 .

The rotor 130 is prevented from rotating by the side walls of the groove 188 of the guide sleeve 140. be done. However, due to the presence of the sidewalls of groove 188, the half plate of rotor 130 The plug 164 runs along the secondary cam surface 154 of the full lug 152 of the plunger 120. It slides down towards the rim of the plunger 120.

As plunger 120 and rotor 130 move forward, leaves 178 of contact 172 , the end of the guide sleeve 140 is moved into the bore of the retainer 74 to remove the retainer. An electrical connection is made with 74. As a result, the flashlight bulb 40 The electric circuit is closed and the light bulb 40 emits light. Guide sleeve 140 and retainer 7 4, half lug 164 of rotor 130 remains in groove 188. It is held between two walls. Therefore, if the flashlight 3o is When the flashlight 30 is in the closed state, the half lug 164 leaves the groove 188. with a minimum amount of movement and producing an audible sound, as when rotating after It is lit without any problem. Before rotor 130 rotates along guide sleeve 140, When the pushbutton 68 is released, the plunger 120 and rotor 130 are Return to the respective positions shown in the figure. As a result, necessary information is provided when performing law enforcement work, etc. If there is, Franchlite 30 can be used quietly.

When the bush button 68 is pushed further, the tip of the half lug 164 will fit into the groove 188. Clear (get over) the side edge. Is the button 68 completely pushed in? When plunger 120 moves to its maximum axial limit, coil spring 72 The spring pressing force from the half flag 164 and the inclined surface of its support surface 191 cooperate The rotor 130 is then rotated to the position shown in FIG. Contact 172 is also The same amount as the flag 164 moves along the support surface 191 is aligned with the rotor 130. rotate together. When the button 68 is in this state, the tongue 70 is The bottom of the cavity 110 of the button 68 has been reached. However, the plan The O-ring 126 of the switch 120 connects the O-ring groove and the small diameter bore of the switch body 56. It is still under pressure between the two. The trough 162 of the rotor 130 is a plunger. When the peak of the primary cam surface 150 of the camera 120 is reached, an audible "click" sound is emitted. live.

When the button 68 is released, the apex of the half flag 164 will move along the slope. Since the rotor 13 slides in the direction of the portion 192, the pressing force of the coil spring 72 causes the rotor 13 to o1 plunger 120 and contact 172 are pushed axially rearward. Rotor 13 0 is an angle of 45'' from the groove 188 of the guide sleeve 140 to the trough 192. Rotate slightly beyond. Dark area 160 and valley 1 between half flags 164 62 indicates that the primary cam surface 150 of the plunger 120 is part of the dark portion 160 of the rotor 130. The rotation of the rotor 130 is not hindered except in the area where it slides along the next cam surface. . This is because only the cam follower surface of the half flag 164 is connected to the guide sleeve 140. This is because it comes into contact with the supporting surface. In response to the pressing force of the coil spring 72, the rotor 13 0 rotates continuously, the plunger 120 has a corresponding half lug 164. It is pushed far enough back until it comes to rest in the trough 192. In this position, the rotor 130 has a corresponding position on the primary cam surface 150 of the plunger 120. It is rotating beyond. In the state shown in FIG. 19, the contact 172 has a 45" The retainer 74 has been rotated slightly beyond the The wiping action is performed between the edges of each part of the leaf. This wiping action is axial movement of the contact and rotational movement of the contact achieved through rotation of the motor 130; is done as a result of. This wiping action reduces the current flow when the circuit is closed. is enhanced. While the contact 172 rotates due to the rotation of the rotor 130, the switch It is not necessary for contact 172 to rotate the same amount as rotor 130 for each operation of 45" The following rotations may also occur:

In the state shown in FIG. 19, the plunger 120 must be fully retracted by hand. This allows the plunger 120 to be rotated to open the pocket of the guide sleeve 140. This allows the tongue 70 and its corresponding shelf to be moved back into the cut 190. At the same time, orient the button 68 and the tongue 7o so that they align with each other. arise. This will actually lock the flashlight 3o. . However, the button 68 or plunger 120 is not in the position shown in FIG. The pressing force to prevent return is between the O-ring 126 and the bore of the switch body 56. It is nothing more than a frictional force acting on the This pressure is applied to the button 6 to unlock it. After rotation to the position, it is defeated by pressing the button 68.

The O-ring 126 of the plunger 120 provides the desired uniformity to smooth the operating force of the switch. It contributes to the generation of a uniform resistance force, that is, a tensile force (drag force). Also, 0 phosphorus When the switch is in the "on" state, the actuator component (i.e. In other words, the pressing force of the spring is not acting on the plunger 120 and the button 68). It serves to hold these actuator parts in place when needed.

To return the tail cap switch to the state shown in Figure 17, press the button 68. push the plunger 120 against the rotor 130 and move it forward. . The primary cam surface 150 of the plunger 120 is connected to the primary cam surface 150 of the dark portion 160 of the rotor 130. The rotor 130 is pressed against the pressing force of the coil spring 72 by contacting the rotor 130. Ru.

The longitudinal sides of the half lug 164 touch the support surface 194 of the guide sleeve 140. As soon as it rears up, the half flag] 64 descends on the support surface (second support surface) 196. Return to groove 188. The rotor 130 and contacts 172 then move 90''. The plunger 120 can be rotated as before to relock the switch.

According to the flashlight equipped with the switch of the above embodiment, the button 68 The skirt of the switch body 56 is guided along the outer surface of the switch body 56. Button button 68 is due to any impact force applied from the side to the button 68. Rocking is substantially prevented. This is the skirt switch book The button should be placed close to the body, and the button and the plunger should be firmly connected. Both because they are interconnected. Also, the skirt is attached to the switch body. Since it is located on the side, the button 68 can be moved to the locked position and the unlocked position. You can easily rotate it between the two. Also, tongue and butshubo The interaction with the tongue is combined with the locking function of the plunger and guide sleeve. Locking function through tail camp, which acts as a locked locking function is preferably equivalent to the locking function produced by the plunger.

Contacts through the use of plungers, rotors, and corresponding cam surfaces and cam follower surfaces rotation, which provides a wiping action on the contacts and , an audible "click" sound can be generated when the switch mechanism is operated.

Furthermore, the button and plunger are partially advanced to close the circuit. The flashlight can be turned on instantly without producing an audible clicking sound. You can also set it to the “on” state.

Importantly, except when full and half lugs are retained within groove 188, Even if the full lug and half lug are aligned, the rotor will not be stable during the plunge. This means that the equilibrium state cannot be reached.

Therefore, as soon as the half lug is freed from the constraint of the groove 188, the half lug It becomes possible to rotate freely in response to the pressing force of the coil spring.

It should be noted that while the embodiments described above are preferred, other configurations are possible. Should. The embodiments of the present invention described above are preferred embodiments, and the present invention The scope of the present invention extends beyond such implementation. It is not limited to the examples. Those skilled in the art will appreciate that it deviates from the spirit and scope of the invention. Various other configurations could be considered without departing from this.
