Description

  The present invention relates to an operation error prevention tool for preventing an operation error of a rocker switch attached to a wall portion such as a casing of an electronic device.

Manufacturers that develop electronic devices have taken various measures to prevent accidents caused by incorrect operation of the power switch of the electronic device. For example, the operation part of the rocker switch is covered with a slidable cover member to prevent the switch from being turned on or off by mistake (for example, Patent Document 1). In addition, a structure in which the operation unit is recessed with respect to the front surface of the rocker switch has been proposed. Alternatively, it has been proposed to incorporate a lock function in the rocker switch itself.
JP 2001-84858 A

  However, in the conventional measures, it is necessary to change the structure of at least one of a wall portion such as a housing to which the rocker switch is attached and the rocker switch. For this reason, there is a problem that it cannot be applied to existing electronic devices. When applied to an existing electronic device, it is necessary to redesign the rocker switch and the housing, which increases the cost of the electronic device.

  Furthermore, when the operation part of the rocker switch is covered with a slidable cover member, erroneous operation of the operation part can be prevented, but the operation part cannot be contacted. For this reason, when the switch should be turned on or off in an emergency or the like, a quick operation cannot be performed, and there is a problem in safety. Further, if the operating portion is simply recessed, for example, when a sharp object collides with the operating portion, there is a possibility that the switch is switched on and off.

  An object of the present invention is to reliably prevent erroneous operation of a rocker switch.

  Another object of the present invention is to prevent erroneous operation of the rocker switch at a low cost.

  Another object of the present invention is to prevent a rocker switch from being erroneously operated without modifying the rocker switch and a wall portion to which the rocker switch is attached.

  Another object of the present invention is to prevent an erroneous operation of the rocker switch without completely covering the operation part of the rocker switch in consideration of an emergency operation.

  In the rocker switch misoperation prevention device according to the first aspect, first, the frame-shaped cover portion is inserted from the tip of the embedded portion while the pressing portion is inclined outward, and is brought into contact with the embedded portion side of the flange. Next, by releasing the urging force to the outside of the pressing portion, the pressing portion is arranged at a position that covers the off-side end (or on-side end) of the operation portion of the rocker switch by the restoring force of elastic deformation. . At this time, since the protrusion of the off-side end (or on-side end) is restricted by the pressing portion, the rocker switch is fixed in the off state (or off state). The on-side end (or off-side end) of the operation unit cannot be pushed. Therefore, it is possible to prevent the rocker switch from being turned on (or turned off). As a result, the erroneous operation of the rocker switch can be reliably prevented by a simple erroneous operation prevention tool.

  Furthermore, in an emergency, the rocker switch operating portion can be freely operated by simply tilting the pressing portion outward, so that the rocker switch can be easily switched between an off state and an on state.

It is arranged at a position covering the off-side end. At this time, the off-side end is held in the pushed-in state, and the on-side end is held in a state of protruding to the opposite side of the embedded portion (that is, in the off state). In this state, by releasing the biasing force to the outside of the other side of the pressing part (for example, the pressing part corresponding to the on-side end), the other side of the pressing part is opposite to the embedding part by the restoring force of elastic deformation. It abuts on the side of the on-side end that protrudes from the side. Then, the rocker switch is fixed in the off state by the protrusion of the off-side end being restricted by the pressing portion. The on-side end of the operation unit cannot be pushed. For this reason, it can prevent that a rocker switch changes from an OFF state to an ON state. Similarly, by releasing the urging force to the outside of the holding part corresponding to the ON side end first, the protrusion of the ON side end is regulated by the holding part and the rocker switch is prevented from being turned off from the on state. it can. As a result, the erroneous operation of the rocker switch can be reliably prevented by a simple erroneous operation prevention tool. Further, since the pair of pressing portions are formed, the fixing in the on state and the fixing in the off state can be switched without removing the erroneous operation preventing tool from the rocker switch.

  In an emergency, since the rocker switch can be freely operated by simply tilting one of the pressing portions outward, the rocker switch can be easily switched between an off state and an on state. Since the misoperation prevention tool can be used only by being attached to the rocker switch, it is possible to prevent the rocker switch from being erroneously operated without modifying the rocker switch and the wall portion to which the rocker switch is attached. In other words, the erroneous operation prevention tool of the present invention can be easily attached to the rocker switch that is already attached to the wall and used.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a first embodiment of a locker switch misoperation prevention device of the present invention. The erroneous operation preventing tool 10 is attached to the rocker switch 20 and is attached together with the rocker switch 20 to a rectangular attachment hole 24b formed in the wall portion 24a of the housing 24 of the electronic device 22.

  The rocker switch 20 includes an operating portion 20a, a flange 20b formed around the operating portion 20a, and an embedded portion 20c that protrudes on the opposite side of the operating portion 20a in the flange 20b and is inserted into the mounting hole 24b. And have. The operation portion 20a has a seesaw shape having an on-side end 20d and an off-side end 20e, and either the on-side end 20d or the off-side end 20e protrudes. Plate-like stoppers 20f are fixed to the outer surfaces of the embedded portion 20c corresponding to the on-side end 20d and the off-side end 20e, respectively, in order to hold the embedded portion 20c in a pressed state on the inner surface of the mounting hole 24b. Each stopper 20f is formed in a square shape projecting toward the outside of the embedded portion 20c, and has elasticity in the direction opposite to the stopper 20f.

  The erroneous operation preventing tool 10 is integrally formed by, for example, cutting a plate material having a spring property made of phosphor bronze or the like into a predetermined shape with a press or the like and then bending the plate. The erroneous operation preventing tool 10 includes a cover part 12, a rising part 14, a pressing part 16, and a protruding part 18.

  The cover portion 12 has substantially the same thickness as the flange 20b, and has an opening 12a that is larger than the cross-sectional shape of the embedded portion 20c (the shape of the cross section parallel to the flange 20b) and smaller than the outer shape of the flange 20b. It is formed in a frame shape. The length of the opening 12a (the length in the direction from the rising portion 14 toward the slit 12b) is made smaller than the interval between the tops of the pair of stoppers 20f of the rocker switch 20. The outer shape of the cover portion 12 is substantially the same as the outer shape of the flange 20b.

  The cover part 12 has a slit 12b that extends from the opening 12a to the outer edge of the cover part 12 and cuts a part of the frame shape. By forming the slit 12b, both end portions of the cover portion 12 facing each other across the slit 12b can be moved in the axial length direction of the opening portion 12a. As a result of this movement, the slit 12b has a width that allows the electric wire 26 connected to the rocker switch 20 to be inserted into and removed from the opening 12a. The cover portion 12 is inserted from the tip of the embedded portion 20c and then comes into contact with the embedded portion 20c side of the flange 20b.

The rising portion 14 is formed at a position corresponding to the off-side end 20e (or the on-side end 20d) in the cover portion 12, and the cover portion 12 is in contact with the flange 20b as shown in FIG. , Projecting to the opposite side of the embedded portion 20c beyond the outer edge of the flange 20b. The connecting portion 14a between the rising portion 14 and the cover portion 12 is bent at a predetermined curvature. The curved connecting portion 14a has flexibility, and the rising portion 14 and the pressing portion 16 can be inclined in the central direction of the opening 12a and the opposite direction by the connecting portion 14a.

  The holding part 16 is connected to the tip of the rising part 14. As shown in FIG. 2, which will be described later, the pressing portion 16 has a U shape that protrudes toward the center of the opening portion 12a in a state where the cover portion 12 is in contact with the flange 20b. The U-shaped tip portion is disposed at a position covering the off-side end 20e (or the on-side end 20d). As described above, the end portion (U-shaped tip portion) of the pressing portion 16 that contacts the off-side end 20e of the operation portion 20a has a chamfered shape. For this reason, the off-side end 20e (or the on-side end 20d) is prevented from being damaged by the collision of the pressing portion 16. Further, even when a finger is sandwiched between the pressing portion 16 and the off-side end 20e (or the on-side end 20d), injury is prevented.

  The pressing portion 16 is bent at a substantially right angle with respect to the rising portion 14. For this reason, the connecting portion 16 a between the pressing portion 16 and the rising portion 14 is less likely to bend than the connecting portion 14 a between the rising portion 14 and the cover portion 12. Therefore, even when the pressing portion 16 covers the off-side end 20e (the pressed-off state of the off-side end 20e) and the on-side end 20d is pushed, the pressing portion 16 restricts the protrusion of the off-side end 20e. Therefore, the rocker switch 20 cannot be turned on from the off state.

  The protruding portion 18 is formed to protrude to the opposite side of the rising portion 14 in the pressing portion 16. For this reason, the pressing part 16 can be easily inclined outward by biasing the protruding part 18 outward. Further, since the tip of the protrusion 18 is chamfered, it is possible to prevent injury when the protrusion 18 is urged with a finger or the like. Further, even when an operator accidentally hits the erroneous operation preventing tool 10 attached to the electronic device 22 together with the rocker switch 20, it is possible to prevent the projecting portion 18 from being injured.

  FIG. 2 shows a state in which the erroneous operation preventing tool 10 is attached to the rocker switch 20. When attaching the erroneous operation preventing tool 10 to the rocker switch 20, first, the protruding portion 18 is urged outward (opposite the center of the opening portion 12a), and the pressing portion 16 is rotated outward about the connecting portion 14a. . While maintaining this state, the opening 12 a of the cover 12 is inserted from the tip of the embedded portion 20 c of the rocker switch 20. At this time, the vicinity of the top of the stopper 20f is pressed against the inner surface of the opening 12a and is temporarily elastically deformed into a flat shape. And the cover part 12 is arrange | positioned between the flange 20b and the stopper 20f in the state contact | abutted to the embedding part 20c side of the flange 20b.

  Next, the pressing portion 16 is disposed on the off-side end 20e of the rocker switch 20 by the restoring force of the elastically deformed connecting portion 14a by releasing the urging force to the outside of the protruding portion 18, and FIG. It will be in the state shown. At this time, the pressing portion 16 may contact the off-side end 20e or may be slightly separated from the off-side end 20e. In this state, in the rocker switch 20, the protrusion of the on-side end 20d is restricted by the pressing portion 16, and is fixed in the off state.

  As shown in FIGS. 1 and 2, when the electric wire 26 has already been wired between the rocker switch 20 and the electronic device 22, both sides of the slit 12b of the cover portion 12 shown in FIG. The electric wires 26 can be positioned in the openings 12a through the slits 12b that are moved in opposite directions and widened.

FIG. 3 shows a state in which the erroneous operation preventing tool 10 is attached to the wall portion 24 a together with the rocker switch 20. When the embedded portion 20c of the rocker switch 20 is inserted into the mounting hole 24b, the stopper 20f is pressed from the inner surface side of the mounting hole 24b of the wall portion 24a toward the embedded portion 20c and elastically deforms into a flat shape. The rocker switch 20 is fixed to the mounting hole 24b by the frictional force between the stopper 20f and the inner surface of the mounting hole 24b, as shown in FIG. The erroneous operation preventing tool 10 is attached to the wall portion 24a together with the rocker switch 20 in a state where the cover portion 12 is sandwiched between the flange 20b of the rocker switch 20 and the wall portion 24a.

  In the state shown in FIG. 3, even if the on-side end 20 d of the rocker switch 20 is accidentally pushed, the protrusion of the off-side end 20 e is restricted by the pressing portion 16. For this reason, the rocker switch 20 does not change from the off state to the on state. That is, an erroneous operation of the rocker switch 20 can be prevented. In addition, when attaching the erroneous operation preventing tool 10 to the wall 24a, it is not necessary to modify the rocker switch 20 and the wall 24a and the mounting hole 24b of the casing 24, so that the rocker switch 20 is already attached to the apparatus. In addition, the erroneous operation preventing tool 10 can be easily attached to the rocker switch 20. At this time, since the slit 12b is formed, it is not necessary to remove the electric wire 26 wired to the rocker switch 20 as described above.

  4-6 has shown the procedure which makes the rocker switch 20 attached to the wall part 24a with the misoperation prevention tool 10 from an OFF state to an ON state. FIG. 4 shows the same state as FIG. 3 described above, and the rocker switch 20 is fixed to the mounting hole 24b by the frictional force between the stopper 20f and the inner surface of the mounting hole 24b. The cover portion 12 of the erroneous operation preventing tool 10 is sandwiched between the flange 20b of the rocker switch 20 and the wall portion 24a. The pressing portion 16 is disposed so as to cover the off-side end 20e of the operation portion 20a.

  When the rocker switch 20 is changed from the on state to the off state, first, as shown in FIG. 5, the projecting portion 18 is urged outward, and the pressing portion 16 is tilted outward with the connecting portion 14a as an axis. Next, the on-side end 20d is pushed into the wall portion 24a, and the rocker switch 20 is turned on.

  Thereafter, by releasing the urging force to the outside of the protruding portion 18, the pressing portion 16 is protruded to the opposite side of the embedded portion 20 c by the restoring force of elastic deformation as shown in FIG. 6. It abuts on the side of 20e. In this state, since the pressing portion 16 presses the side of the off-side end 20e toward the center of the operation portion 20a, the rocker switch 20 does not switch to the off state.

  When the rocker switch 20 is turned off again, the state shown in FIG. 4 can be easily obtained by simply pressing the off-side end 20e with a finger or the like. 1 to 6 described above, the pressing portion 16 may be disposed not on the off-side end 20e but on the on-side end 20d. In this case, the rocker switch 20 is erroneously operated to change from the on state to the off state. Can be prevented.

  As described above, in this embodiment, since the protrusion of the off-side end 20e (or the on-side end 20d) can be restricted by the pressing portion 16, the on-side end 20d (or the off-side end 20e) of the operation unit 20a can be pushed. Disappear. As a result, the state of the rocker switch 20 can be prevented from switching. That is, erroneous operation can be reliably prevented.

  In an emergency, the operation unit 20a can be freely operated simply by tilting the protruding portion 18 outward, so that the rocker switch 20 can be easily switched between an off state and an on state.

Since the erroneous operation preventing tool 10 can be used simply by being attached to the rocker switch 20, it is possible to prevent erroneous operation of the rocker switch 20 without modifying the rocker switch 20 and the wall portion 24a to which the rocker switch 20 is attached. Moreover, since the erroneous operation preventing tool 10 can be easily manufactured by bending the sheet metal, the manufacturing cost of the erroneous operation preventing tool 10 can be reduced.
As a result, erroneous operation of the rocker switch 20 can be prevented at a low cost.

  Since the electric wire 26 can be positioned in the opening 12a through the slit 12b, even when the rocker switch 20 is already attached to the electronic device 22, the erroneous operation preventing device 10 can be used without removing the electric wire 26 from the rocker switch 20. Can be easily attached to the rocker switch 20. That is, the retrofitting of the erroneous operation preventing tool 10 to the rocker switch 20 can be facilitated. Moreover, the erroneous operation prevention tool 10 can be easily detached from the rocker switch 20 without removing the electric wire 26 from the rocker switch 20 during maintenance of the rocker switch 20 or the like.

  Since the end portion of the pressing portion 16 and the end portion of the protruding portion 18 are chamfered, injury can be prevented when the pressing portion 16 and the protruding portion 18 are touched. Further, the on-side end 20d or the off-side end 20e can be prevented from being damaged by the collision of the pressing portion 16. By forming the protruding portion 18, the pressing portion 16 can be easily inclined outward.

  FIG. 7 shows a second embodiment of the rocker switch misoperation prevention device of the present invention. The same elements as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

  In the erroneous operation preventing tool 30 of this embodiment, the rising portion 14, the pressing portion 16, and the protruding portion 18 are integrally formed on both sides of the cover portion 32 that are opposed to each other using a plate material having a spring property made of phosphor bronze or the like. ing. The sizes of the cover portion 32 and the opening portion 32a are the same as those in the first embodiment. The slit 32 b is formed between the two rising portions 14 in the cover portion 32. Other configurations of the erroneous operation preventing tool 30 are the same as those of the erroneous operation preventing tool 10 of the first embodiment. The same rocker switch 20 and electronic device 22 as those in the first embodiment are used.

  FIG. 8 shows a state in which the erroneous operation preventing tool 30 is attached to the wall portion 24 a together with the rocker switch 20. Before the rocker switch 20 is attached to the wall portion 24a, the erroneous operation preventing tool 30 is attached to the rocker switch 20.

  First, by pressing the protrusions 18 outward, the pressing portions 16 are respectively rotated outward about the connecting portion 14a. While maintaining this state, the opening 32a of the cover portion 32 is inserted from the tip of the embedded portion 20c of the rocker switch 20 as in the first embodiment. The cover portion 32 is disposed between the flange 20b and the stopper 20f in a state where the cover portion 32 is in contact with the flange 20b.

  Next, by releasing the urging force to the outside of the protruding portion 18 (in this example, the off-side end 20e) corresponding to the on-side end 20d and the off-side end 20e that is kept pressed, the off-side end The pressing portion 16 corresponding to 20e is disposed on the off-side end 20e of the rocker switch 20 by the restoring force of the elastically deformed connecting portion 14a. Thereafter, by releasing the urging force to the outside of the protruding portion 18 corresponding to the on-side end 20d, the pressing portion 16 corresponding to the on-side end 20d is caused to have elastic restoring force as shown in FIG. Next, it abuts on the side of the on-side end 20d protruding to the opposite side of the embedded portion 20c. In this state, since the pressing portion 16 corresponding to the on-side end 20d presses the side of the on-side end 20d toward the center of the operation portion 20a, the rocker switch 20 is fixed to the off state and switched to the on state. There is nothing.

The rocker switch 20 to which the erroneous operation preventing tool 30 is attached is fixed to the attachment hole 24b by inserting the embedded portion 20c into the attachment hole 24b of the wall portion 24a, as in the first embodiment. In addition, when the electric wire 26 has already been wired between the rocker switch 20 and the electronic device 22, both sides of the slit 32b of the cover part 32 shown in FIG. Can be easily positioned in the opening 32a through the slit 32b. Therefore, the erroneous operation preventing tool 30 can be retrofitted to the rocker switch 20 already attached to the electronic device 22.

  FIG. 9 shows a procedure for turning the rocker switch 20 from the off state to the on state. First, the protrusion 18 corresponding to the off-side end 20e is urged outward, and the pressing portion 16 corresponding to the off-side end 20e is inclined outward. Next, the on-side end 20d is pushed into the wall portion 24a, and the rocker switch 20 is turned on. Thereafter, by releasing the urging force to the outside of the protruding portion 18 corresponding to the off-side end 20e, the pressing portion 16 is caused by the restoring force of elastic deformation as in the first embodiment (FIG. 6). , Abuts on the side of the off-side end 20e protruding to the opposite side of the embedded portion 20c.
