Abstract

PURPOSE:To improve handleability, by a method wherein a motion-relaying device which transmits a sinking motion of the lock button to a lock piece and releases an engaging state between the lock piece and a main body case, is provided between a middle point between elastically repulsive members for a lock button and the lock piece. CONSTITUTION:A switch button 8 is fitted on an outer wall of a main body case 1, and both a lock button 9 and a lock piece 14c whereby the switch button 8 is locked at the closed position of a switch, are provided. Elastically repulsive members 9a, 9b are located between both ends in the direction of the width of the lock button 9 and the outer wall of the main body case 1, and the lock button 9 is always protruded by their repulsive force from a window 8c. A motion-relaying device 9c is also provided between a middle point between the elastically repulsive members 9a, 9b and the lock piece 14c in the main body case 1. When the lock button 9 is pushed and sunk, a locked state that a switch button 8 is kept at the closed position of the switch by the lock piece 14c through the motion-relaying device 9c, is released. Since the lock button 9 and the switch button 8 are integrally formed, the lock is released and then the switch-opening operation can be, without intermission, done, while the main body case 1 is gripped by hand.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to electric shavers, Franche lights, and other small electric appliances, and particularly relates to improvements in locking means for switch buttons.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 1 denotes a synthetic resin main body case with electrical insulation properties, which is composed of two parts, a front case 2 and a back case 3, which are butted against each other at their side faces, and has a flat box shape as a whole. Also, at the bottom, a container-shaped bottom case 4 made of synthetic resin such as ABS is sandwiched between front and back cases 2 and 3. An outer cutter holder 5 is detachably attached to the upper part of the main body case 1, and an outer cutter 6 made of a 2.7 Kel cobalt electroformed or pressed thin stainless steel plate is attached to the outer cutter holder 5 in an arched shape. It is strung up. 7 is a sharp edge block that rotatably protrudes from the main body case 1;
Reference numeral 8 represents a switch button for opening and closing the power source and for operating the protruding blade block 7, and reference numeral 9 represents a lock button for preventing the switch button 8 from being moved inadvertently. Further, numeral 10 is a light emitting diode for displaying power on to indicate that charging is in progress. The main body constructed in this way has tended to become thinner in recent years, and has a flat shape with the abutting surfaces of the two-part case located on the side surfaces, and absorbs the force applied to the front and back surfaces. There is an urgent need to improve mechanical strength and eliminate squeaks from the case.

Therefore, in the above embodiment, shock-absorbing elastic plates 11a and 11b are provided on both side surfaces of the main body case 1, that is, on the abutting surfaces of the front and back hook cases 2 and 3, and on both side surfaces of the outer blade holder 5.
-12a and 12b are installed. This elastic plate 11a
-11b, 12a, and 12b are made of high-pressure polyethylene and preferably have a Shore hardness of about 70 to 80.
mm), and is formed into a large, arched shape, so that the inner surface is recessed to exhibit surface elasticity rather than local elasticity. It is also possible to form it with a silicone rubber plate.

Next, the driving portion housed in the main body case 1 will be explained with reference to FIG.

This type of small electric appliance, especially one such as an electric razor in which a slide-type switch button 8 is turned on and off while holding the main body case 1 in the hand, is easy to operate, especially for left-handed people. For this reason, it is desirable to enlarge the shape of the switch button 8. In addition, considering when carrying the device, it is desirable to provide a lock button 9 for locking the switch button 8 in the closed position to prevent the switch from being accidentally turned on by being hit by other items in a bag or the like. Rarely 4゜In this case, the lock button 9 may be provided independently on the outer wall of the main body case L in a different position from the switch button 8, but it would be better to continue holding the main body case L with your hand after unlocking. 0721 Exit 9 so that you can operate the switch by
It is preferable to provide the switch button 8 integrally with the switch button 8. In this case, it is preferable to provide a lock button 9 across the width direction perpendicular to the sliding direction of the switch button 8, taking into account left-handed users.

Therefore, a lock button 9 and a switch button 8 that partially covers the lock button 9 are attached to the outer surface of the front case 2 so as to be able to slide freely on the outer surface. Insert the side posts 8a and 8b into the guide holes 13 of the front case 2.
A and 13b are inserted into the mounting holes 14a and 14b of the polyacetal switch moderation plate 14, respectively, and the protruding tips are heat welded to sandwich the front case 2 between the switch button 8 and the switch moderation plate 14. become. At this time, as shown in Figure 3, the polyacetal Rofuku button 9
is housed between the switch button 8 and the front case 2 so that a portion thereof protrudes from the window 8c of the switch button 8, and the lock button 9 is located at both ends of the left and right width direction, and is slightly inclined downwardly and outwardly. Since the lock button 9 is provided with tongue-shaped elastic rebound members 9a and 9b having elasticity that extend to the sides, the lock button 9 can be locked as shown by the broken line by pressing the protruding portion as shown in FIG. The elastic repulsion members 9a and 9b are deformed to slightly expand and descend with elasticity. The elastic repulsion members 9a and 9b may extend inward. Two pins 9C and 9d are protruded from the center of the lock button 9, and are inserted into elongated holes 15a and 15b of the front case 2, respectively, and one pin 9C that passes through the elongated hole 15a is operable. It is a relay means and is in contact with the arm portion (indicated by @ in FIG. 3) of a lock piece 14c integrally formed on the side edge of the switch moderation plate 14, and is raised and lowered in response to the rise and fall of the lock button 9. . A triangular hook protrusion 16 is formed on the inner side edge of the elongated hole 15a, and the protrusion of the lock piece 14c engages with the protrusion 16 when the switch button 8 is normally closed. When pressed by 9c, the bulge descends and comes off from the projection 16, releasing the locked state. The other pin 9d inserted into the elongated hole 15b serves as a sliding guide for the lock button 9 and restricts its sliding along the elongated hole 15b.

As described above, the lock button 9 needs to be easy to operate regardless of the user's dominant hand.

For example, as shown in FIG. 5, even if the finger H is placed on only one end of the lock button 9 in the left and right width direction, the lock button 9 itself is long and soft in the width direction, and the width of the lock button 9 is long and soft. Elastic repulsion members 9a and 9b are provided at both ends of the lock button 9, and the pin 9c, which is an operation relay means for pressing the lock piece 14c that creates a locked state, is the elastic repulsion member 9 of the lock button 9.
Since it is provided at an intermediate position between a and 9b, if only the left end side is pressed, the elastic repulsion member 9a on the left end side will expand and be elastically deformed, and the left half of the lock button 9 will also be significantly elastically deformed, and the right half will be particularly deformed. Regardless of the elastic deformation of the right-end elastic repulsion member 9b, the pin 9C descends and the locking piece 14c is pressed to release the locked state.

In other words, elastic repulsion members 9 are provided at both ends of the lock button 9 in the width direction.
a and 9b are provided, so when only the left end side is pressed, the elastic repulsion member 9a on the left end side mainly acts, and the pressing operation force is light.

This leads to a large push amount of the lock button 9, and therefore, even when pushed on one side, the elastic repulsion member 9a
The pin 9C located at the intermediate position between the pins 9b can be pushed in sufficiently to reliably release the locked state. Conversely, if a right-handed user presses the right end side of the lock button 9, the opposite effect will occur and the locked state will also be reliably released.

In addition, by integrally molding the elastic repulsion members 9a and 9b on the lock button 9 to protrude, the elastic repulsion members 9a and 9b can be slid integrally with the lock button 9 and the switch button 8 when the switch button 8 is slid. Because it is possible to
It is possible to slide the lock button 9 while keeping the pressure of the lock button 9 constant during the slide.In other words, it prevents the finger from getting caught during the slide, and the moderate repulsive force applied to the fingertip increases the feeling of the fingertip getting caught. This allows the slide operation of the switch 608 to be performed smoothly.

By pressing the lock button 9 in this manner, the lock piece 14C is pressed down by the pin 9C, and the bulge at the tip is removed from the vertical surface of the triangular hook projection 16 of the elongated hole 15a, releasing the locked state. If the switch button 8 is then slid, the switch moderation plate 14 will slide. Elastic arms 14d and 14e are integrally formed at both lower ends of the switch moderation plate 14, and engage the moderation pin 17 on the inner surface of the back case 2 in three stages to generate elastic force. Further, a round hole 14f is provided in the center of the switch moderation plate 14 that slides in this manner, into which an operating pin 18a of the switch section 18 (indicated by a broken line in FIG. 2), which will be described later, is fitted.
You will have to slide 8. Along with this, a hook-shaped portion 14g is integrally formed on the upper side of the switch moderation plate 14. This hook-shaped portion 14g is located in the second stage of the switch moderation plate 14, which is positioned in the upward sliding state in three stages, that is, in the state in which the power switch part 18 is turned ON for the first time.
The notch 19 engages with the right end notch 19a of the seesaw plate 19 and rotates and protrudes the edge block 7 in three stages, that is, while the switch portion 18 remains in the ON state.
This is to push up a.

In other words, the seesaw plate 19 is connected to the rotating pin 2 on the inner surface of the back case 2.
0 is fitted with a rotation hole 19b, and can be rotated around this pin 20. The pin 19b is provided at the left end, and this pin 19b is inserted into the horizontal slide hole of the rotation 1 mulberry lever integral 21. 21a, and the seesaw plate 19
The tip of the rotating bottle 20 further protrudes from the seesaw plate 19 when it is fitted into the rotating bottle 20, so this tip engages with the vertical slide groove 21b of the rotating operating lever unit 21. .

Therefore, if the seesaw plate 19 rotates counterclockwise,
The bottle 19b slides within the horizontal slide hole 21a of the rotary operating lever unit 21 and acts to push down the lever unit 21, while the lever unit 21 is
a vertical slide groove 2 engaged with the pivot pin 20;
Since the rotation is restricted by 1b, the rotation operation lever unit 21 ends up sliding downward.

An inverted-shaped elastic lever 2 is attached to the upper part of the rotation operation lever integrated 21.
1c is integrally formed, and its tip engages with a right-angled notch 7b provided slightly rearward of the rotating pin 7a of the sharp blade block 7, and the rotating pin 7a is connected to the front case 2. It engages with rotation recesses 23 provided on both sides of the protruding window 22 of the scraper blade block 7.

Therefore, when the rotary operating lever unit 21 slides downward, the elastic lever 21C engaged with the right-angled notch 7b acts to press the notch 7b downward, but the edge-to-edge blade block 7 rotates. Since it is rotatably supported by the movable pin 7a, this blade block 7 rotates and closes the protruding window 2.
2, it will protrude at a right angle. At this time, while the elastic lever 21C moves downward, the notch 7b rotates, so the elastic lever 21c is elastically deformed inward in a slightly arched shape, and then, after the blade block 7 protrudes, it returns to its original position. The state will be restored, and at this time, click error will occur.
A protruding state can be maintained.

Reference numeral 24 denotes a motor, and an eccentric stand 27 equipped with an eccentric pin 26 is attached to the rotating shaft 25, and is projected upward from the through hole 29 of the drive stand 28. In this state, screws 30 and 31 are inserted into the motor 2.
Screw into the screw holes 32 and 33 of No. 4 and fix.

34 is a drive converter made of bo+f acetal, and four deformed S-shaped thin elastic legs 35 are integrally provided at the side end in the reciprocating direction, and each leg 35 has two legs on each side attached to a mounting base 36. Four round pins 37 are connected to each other, and four round pins 37 are protruded from the bottom surface of the mounting base 36.
The drive converter 3 is inserted into the mounting hole 38 of the drive base 28.
4 and the drive base 2 are temporarily fastened, and in this fastened state, the eccentric pin 26 is fitted into the elongated hole 39 on the back surface of the drive converter 34. Further, a drive rod 40 is integrally formed on the upper surface of the drive conversion body 34, and a hair catch plate 41, an inner blade push-up spring 42, and an inner blade mount 43 are sequentially attached to the drive rod 40, and a mounting bracket 44 is attached to the drive rod 40. Extraction has been stopped.

Reference numeral 45 denotes a semicircular arc-shaped inner cutter body that is detachably attached to the inner cutter mounting base 43. The drive base 28 and the drive converter 34 temporarily fixed together are the sum (T3) of the wall thickness of the drive base 28 (T) and the wall thickness (T2) of the mounting base 36 of the drive converter 34. Concave/! Ifi 46 is formed on the inner wall of the front case 2, and is slid into the groove 46 for positioning. For the press-fitting locking force required at this time, it is appropriate for the material of the drive converter 34 to be made of a soft or elastic synthetic resin such as nylon or polyacecool.

In this state, the protruding window 22 of the sharpening blade block 7 is closed by a shielding plate 47 formed on the front surface of the drive base 28 to prevent hair from entering.

Further, elastic arms 48 extending from both ends of the drive base 28 are exposed through openings 49 opened at the mating surfaces of the front and back cases 2 and 3, and as shown in FIG. Its tip projection 48a is engaged with a hooking recess 50 on the inner surface of. Therefore, to remove the outer cutter holder 5, pinch its left and right walls as shown in Figure 6, and then pull it up.
As shown by the broken line in the figure, the elastic arm 48 bends inward, the tip protrusion 48a comes off the hook recess 50, and the outer cutter holder 5
can be removed. At this time, as shown in FIG.
Due to the inward deflection of the base, a gap a is created at the base. Generally, hair tries to enter the main body case 1 through this gap, but in this case, the shock-absorbing elastic plate 11a
- Since the upper surface of llb has elasticity and abuts against the base of the elastic arm 48, the above-mentioned gap can be prevented from occurring, and there is no need to attach a filler such as a sponge body to the conventional gap. do not have.

When removing the outer cutter holder 5, use the elastic arm 4.
Sufficient lifting force is required to deform 8 inward. Generally, a recess is provided in the finger rest at the finger rest position of the outer cutter holder 5 for this purpose, but this is undesirable as it causes discomfort and pain to the fingertips. However, in this case, elastic plates 12a and 12b are attached to the side surface of the outer cutter holder 5 at the finger contact positions, and meat relief recesses 12c and 12d are provided on the inner surface at the position where the finger hits the strongest, so the As shown, the elastic plates 12a and 12b are recessed in response to fingertip force, and the finger rest forms a surface to prevent slipping. Fine irregularities 12e in the lower part of Fig. 6
・12[ is a component that effectively prevents slipping when the outer blade holder 5 is attached.

Next, the power supply section will be explained in detail with reference to FIGS. 8 and 9.

8 and 9, 51 is a wiring board, a transformer 52 with a temperature fuse 57, a rectifier 53, and a rechargeable battery 54.
, a display light emitting diode 55, and a display current limiting resistor 56 are respectively soldered and mounted at the positions indicated by the dashed lines in FIG. Welded.

The wiring state is as shown in FIG.

As shown in FIG. 11, the switch section 18 has a T-shaped movable contact plate 60 on contacts 65 and 66 exposed on the lower surface of the wiring board 51.
, attach the operation plate 61 thereon, cover the mounting frame 62 from above, and insert eight pins 63 protruding from the mounting frame 62 into positioning holes provided on the periphery of the switch section 18 of the wiring board 51. 64 and the bins 63 in the four corners.
Only the pins 63 are thermally deformed and used as fixing means, and the remaining four pins 63 near the center are left to protrude as they are and are used as positioning pins for the rechargeable battery 54. A conductive plate 67 with a U-shaped tip is spot welded to one end of the rechargeable battery 54, and a plurality of long holes 69, 70, and 71 are formed in a connecting plate 68 protruding from the tip of the switch section. The long holes 69, 70, and 71 are bent from each position according to the total length of the rechargeable battery 54, and the U-shaped holes are inserted from below into the open state of the long holes 69, 70, and 71 that are formed when bent. Temporary positioning can be achieved by inserting the conductive plate 67 and pulling it upward, and soldering can be carried out as is. Furthermore, by providing the elongated holes 69, 70, and 71, it is also possible to prevent deformation stress during bending from affecting the inside of the wiring board 51. Note that a large number of holes 72 are provided on the back surface (upper surface in FIG. 12) of the switch section 18 to partially expose the contacts 65 and 66.
It has a heat dissipation effect when the contacts open and close.

Next, a method for manufacturing the wiring board 51 will be explained.

In FIG. 13, first, conductive pieces 73 patterned based on the wiring diagram shown in FIG. 10 are interconnected and molded so that they do not fall apart individually. The base material of the conductive piece 73 is a thin plate made of a tin-containing cupronickel alloy with a thickness of 0.12 to 0.2 mm, and is patterned by pressing or etching. Although the pattern shown in FIG. 13 is for one machine, it is convenient for post-processing to continuously form it into a hoop-shaped thin plate.

Next, this patterned conductive piece 73 is loaded into a synthetic resin injection mold, and a substrate 51 having a thickness of 2n is molded from glass fiber-containing ABS resin as shown in FIG. In this state, the conductive pieces 73 are connected to each other and are not configured as a circuit, so they are cut by a press at a point indicated by θ in FIG. 13. At this time, the stress caused by pressing tends to promote partial deformation of the wiring board 51, but in this case, the cut portions are placed on the outer periphery of the board 51, for example, as shown at 74, 75, and 76, thereby preventing cracks due to the stress.
Chips and deformation can be suppressed.

In particular, by detouring the conductive piece 73 to the outside of the substrate at the portion indicated by the reference numeral 74, the cut portion can be actively moved away from the substrate 51, and the degree of freedom in pattern creation can be improved.

Further, the portion indicated by the reference numeral 76 is connected by making a detour to connect the conductive pieces 73, but the broken line portion is cut while leaving a certain length.

By cutting outside the board in this way, the wiring board 5
1 to form partial protruding pieces Kr, Kt, K:I, and when this wiring board 51 is assembled into the main body case 1, the press edges are caught on the inner wall surface of the main body case 1 and have elasticity. Therefore, the wiring board 51 can be simply pushed into the main body case 1 during assembly.

The above-mentioned power supply part is a rechargeable power supply that is equipped with a transformer 52 itself, but it has two types of power supply that are popular in recent years: a direct drive power supply using an external power supply, and a rechargeable power supply that is charged by an external power supply. In the case of a 2-way type, it is inconvenient to manufacture a separate wiring board from the standpoint of versatility and economy. Therefore, a method for manufacturing a wiring board that satisfies both will be described below.

Regarding the rechargeable power supply, as explained in Figures 10 and 13, the circuit of the 2-way type is shown in the first
It is shown in Figure 5. Pl is the so-called adapter side that converts commercial power to the necessary low DC voltage, and fuse TFt,)
It consists of a lance T4 and diodes DI and D that rectify the alternating current low voltage of the transformer T4 into direct current low voltage, and the output thereof is supplied to the main body side power supply P2 through a plug P3 shown by a broken line in FIG. The main body side power supply P2 has a charging current limiting resistor R8,
It consists of a rechargeable battery 54, a light emitting diode 55 for display, a current limiting resistor 5G for display, and a switch section 18', and the terminal of the motor 24 is connected to the output end. This main body power Rpz
FIG. 17 shows the patterned state. The pattern itself is the same as that of the rechargeable power supply described above in FIG. 13, and the shape after injection molding is also the same, but the portion cut by press working (indicated by ■) is slightly different.

The major differences are as follows. In the one shown in FIG. 17, the first
As shown in Figure 6, a conductive piece 80 connects the connecting pins 78 and 79 of the front-shaped bottom case 4' into which the plug P is inserted and connected.
・While 81 was left without press cutting, 13th
The one shown in the figure has the above-mentioned conductive piece 8 on the power supply connection plate 77.
0.81 is removed by press cutting, leaf springs 82 and 83 are left, and these leaf springs 82 and 83 are configured to slide into contact with a plug blade 84 that is inserted into a commercial power outlet.

Therefore, the dedicated wiring board 51 for the rechargeable power supply and the 2-way
- There is no need to mold 51' individually, and it is only necessary to slightly change the cutting position by press working, for example, by simply replacing the punch position of the press mold, which is economically superior.

In this method of manufacturing a wiring board, in which pre-patterned conductive pieces are injection-molded with synthetic resin as a mechanical strength structural material and embedded, it is important to note that the buried conductive pieces are bent into a curved shape due to the injection molding pressure. The substrate itself may warp due to distortion or a difference in shrinkage rate between the conductive piece and the synthetic resin. For this reason, when parts such as wide transformers or straight rod-shaped rechargeable batteries are mounted and mounted, gaps tend to be created between the board and these parts, causing parts to wobble and imperfections in the soldered parts. Undesirable.

Therefore, in this case, the surface of the wiring board 51 on which the components are mounted, that is, the surface 51a shown in FIG. 9, is almost completely covered with synthetic resin, while the surface on which the component lead wires are soldered In other words, the presser rib 87 which opens most of the surface 51b appearing in FIG. 19 and prevents the conductive piece 73 from lifting up.
88, 89, and 90 are provided, and these presser ribs 87,
By extending and intersecting 88, 89, and 90 in a straight line, it is formed so that the warp due to the surface 51a side is pulled in the opposite direction and absorbed. Of course, it is possible to absorb this type of shrinkage strain by mixing insulating reinforcing materials such as glass fibers into the synthetic resin, but this is insufficient, so a linear shape with strong mechanical strength is used. By arranging the conductive pieces 73 in a lattice pattern with a large area within the frame, it is possible to improve the holding performance of the conductive pieces 73 during molding, making it easier to prevent positional displacement due to injection pressure, and also to prevent the conductive pieces 73 from being exposed within the frame. Since the conductive piece 73 is wide, thermal deformation of the synthetic resin by the tip of the soldering iron during soldering of components and partial lifting of the conductive piece 73 due to this thermal deformation can be prevented. The structure of the power supply part and the manufacturing method of the wiring board described above can be effectively applied not only to electric shavers but also to refillable flood lamps and other small electric devices.

Note that the power supply connection plates 77 and 77' have projecting pieces 85 and 85 on both ends.
85' is temporarily assembled by elastically fitting into recesses 86 and 86' provided on both inner walls of the boat-shaped bottom cases 4 and 4'. An example thereof is shown in FIG.

In addition, 91 and 92 in Fig. 14 are the rechargeable battery 54 and the motor 24.
cushioning material in the form of sponge or rubber tape, each elastically pressed.
The hook-shaped hooks 93 and 94 for easily attaching the elastic plates 11a and 11b to the main case 1 are protrusions, and the two-part case 2
- The notch formed on the mating surface of No. 3 is for elastically deforming and hooking into the hole 95, and when the elastic plates 11a and 11b having an arcuate cross section are deformed by external force, the above hook is attached to the protrusion 93.
- 94 expands and deforms to hold it more strongly and can compensate for the amount of deformation of the elastic plates 11a and 11b.

Also, for this purpose, a gap S is provided between the mating surfaces of the front and back cases 2 and 3 and the elastic plates tia and llb, as shown in FIG. 14.
