Description

  The present invention relates to a switch operation adapter used for switch operation.

  In a power transmission / distribution system, power generated at a power plant is transmitted / distributed to each home, facility, etc. while gradually decreasing the voltage at a plurality of substations. In such a power transmission / distribution system, electric facilities (on-site equipment) installed at each substation are managed by remotely operating the control station device installed at the control station. Such a control center apparatus includes a control panel provided with various switches for remotely operating field equipment.

  The switches provided in the control center device are provided in the same number as the number of field devices to be remotely operated and the number of locations to be remotely operated in the field devices. In recent years, the number of switches provided on the control panel has increased with the increase in the number of field devices to be remotely operated and the number of locations to be remotely operated in the field devices.

  As the number of switches increases, the size of each switch provided on the control panel is reduced as compared with the conventional switches. In addition, the size of each switch provided in the control panel has been reduced as compared with the conventional switch in accordance with the recent miniaturization of the control panel.

  The switch provided on the control panel includes a torsion type operation switch that is operated by being gripped and twisted by an operator. When such a twist type operation switch is miniaturized as described above, it is difficult to grasp it with the entire hand. In this case, the operator performs an operation by twisting the operation switch with the fingertips, specifically, the fingertips of only the first finger and the second finger while holding the twisting operation switch.

  As a technology related to the twist type operation switch, in the conventional operation knob attachment that can be attached to and detached from the bending operation knob disposed in the operation portion of the endoscope, the information display portion of the bending operation knob is formed to be exposed. There has been a technique in which a cutout portion is provided (see, for example, Patent Document 1 below).

JP 2007-222651 A

  However, as described above, when the twist type operation switch is reduced in size, it becomes difficult to grasp the operation switch. For this reason, the conventional method of twisting a twisting type operation switch as described above using a hand or fingers is applied to the operation switch when a miniaturized twisting type operation switch is to be operated. There was a problem that it was difficult to apply force and the operability was poor.

  Moreover, the conventional method of maintaining the twisted state with only the first finger and the second finger is a state in which a miniaturized twist type operation switch is continuously twisted for a long time, for example, during a trial operation of a local device. When it is necessary to do this, there is a problem that the fingertips easily slip with respect to the torsion type operation switch due to sweat or the like, and it is difficult to keep the operation state of the local equipment constant. When the operating state of the local equipment changes during the trial run, there are problems that the equipment including the local equipment involved in the trial run has troubles or the trial run fails.

  In addition, the conventional method of maintaining the twisted state with only the first finger and the second finger is, for example, the operation of the fingertip so that the fingertip does not slip with respect to a miniaturized twist type operation switch. When the switch is continuously twisted with a strong force for a long time, there is a problem that the first finger and the second finger may get tired or the skin may become scratched.

  As described above, downsizing of various operation switches including a twist type operation switch is performed in order to arrange an increased number of operation switches in a limited space in the control panel. For this reason, it is difficult to replace the downsized operation switch with a large operation switch as a countermeasure against the above-described problems. Moreover, replacing an existing miniaturized operation switch with a large operation switch is inferior in feasibility because it costs a lot of money. Further, as described above, since the purpose of downsizing various operation switches including the twist type operation switch is to reduce the size of the control panel, it is preferable to replace it with a large operation switch as a countermeasure against the above-mentioned problems. Absent.

  Also, in a control panel provided with a small operation switch, the distance between the switches is small in order to reduce the size of the control panel. There is a concern that the operation switch may contact an operation switch adjacent to the operation switch and operate an unnecessary operation switch unintentionally. For this reason, it is difficult to replace the downsized operation switch with a large operation switch.

  An object of the present invention is to provide a switch operation adapter capable of easily and surely operating a miniaturized twist type operation switch in order to eliminate the above-described problems caused by the prior art.

  In order to solve the above-described problems and achieve the object, the switch operation adapter according to the present invention is fitted to the tip of a twist type operation switch that switches the connection state of an electric circuit by twisting around an axis. A socket portion extending in a direction away from the tip portion in a state in which the recess is fitted to the tip portion, and a direction intersecting the extending direction of the socket portion as a longitudinal direction. And a handle portion connected to the socket portion at a position eccentric from the central portion in the longitudinal direction.

  In the switch operation adapter according to the present invention as set forth in the invention described above, the concave portion opens in the direction of the distal end and the outer peripheral surface of the socket portion.

  In the switch operation adapter according to the present invention as set forth in the invention described above, the concave portion has a tapered shape with a larger opening on the distal end side than on the handle portion side in the socket portion.

  Further, in the switch operation adapter according to the present invention, in the above invention, the recess has a tapered shape that opens so that the width on the outer peripheral surface side is wider than the inner peripheral side in the socket portion. Features.

  Further, in the switch operation adapter according to the present invention, in the above invention, the recess has a step shape in which the width gradually decreases along the direction from the tip side to the handle portion side in the socket portion. It is characterized by that.

  The switch operating adapter according to the present invention is characterized in that, in the above invention, the inner surface of the concave portion is subjected to anti-slip processing.

  In the switch operation adapter according to the present invention as set forth in the invention described above, the socket portion is formed of a material having at least a distal end portion that is transparent.

  Exemplary embodiments of a switch operation adapter according to the present invention will be explained below in detail with reference to the accompanying drawings.

(Embodiment 1)
First, the configuration of the switch operation adapter according to the first embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing a switch operation adapter according to a first embodiment of the present invention. FIG. 1 shows a perspective view of the switch operation adapter according to the first embodiment of the present invention.

  In FIG. 1, the switch operation adapter 100 according to the first embodiment of the present invention includes a socket part 110 and a handle part 120. The socket part 110 has a substantially cylindrical shape. The socket part 110 may have a so-called “kamaboko” shape in which a part of a cylindrical outer peripheral surface is cut off along the axis of the cylinder.

  A concave portion 111 (a fitting opening) is provided at the tip of the socket portion 110 (the end portion opposite to the handle portion 120). The recess 111 opens in the direction of the tip and outer peripheral surface of the socket part 110. That is, the recess 111 opens in two directions, that is, the tip of the socket part 110 and the outer peripheral surface. Thereby, the recessed part 111 has comprised the slit shape dented inside from the corner | angular part in the front-end | tip of the cylinder which the socket part 110 makes.

  In addition, the recess 111 has a tapered shape that opens larger on the tip side than on the handle part 120 side in the socket part 110. Thereby, the shape (cross-sectional shape) in the plane orthogonal to the axial center direction of the socket part 110 of the recessed part 111 has comprised the trapezoid which expands toward an outer peripheral surface side (refer FIG. 4). The shape (cross-sectional shape) of the recess 111 in a plane orthogonal to the axial direction of the socket portion 110 may be a substantially “U” shape or a substantially “V” shape.

  In addition, the recess 111 has a tapered shape that opens larger on the outer peripheral surface side than on the inner peripheral side in the socket portion 110. Thereby, the shape (cross-sectional shape) in the plane parallel to the axial direction of the socket part 110 of the recessed part 111 has comprised the trapezoid which expands toward the front end side (refer FIG. 5). The shape (cross-sectional shape) of the recess 111 in a plane parallel to the axial direction of the socket portion 110 may be a substantially “U” shape or a substantially “V” shape.

  The inner surface of the recess 111 is anti-slip processed. The anti-slip process can be realized, for example, by providing an anti-slip member exposed on the inner surface of the recess 111. The anti-slip member is provided by coating the inner surface of the recess 111 with a material having a high coefficient of friction such as silicon or rubber. Alternatively, the socket portion 110 may be formed of a material having a high coefficient of friction such as silicon or rubber so that the inner surface of the recess 111 is subjected to anti-slip processing.

  The recess 111 is fitted to the tip of the twist type operation switch when the switch operation adapter 100 is used. The socket part 110 extends in a direction away from the tip part in a state where the recess 111 is fitted to the tip part of the operation switch. The length (height dimension) of the socket part 110 in the length direction is the shape of the twist type operation switch to be operated, the shape of the operation switch around the twist type operation switch, and the twist to be operated. It can be set appropriately depending on the size of the interval between the rotary operation switch and the surrounding operation switches.

  Specifically, the dimension in the length direction of the socket part 110 is determined when the switch operation adapter 100 is attached to a twisting type operation switch (see reference numeral 600 in FIGS. 6 and 7) to be operated. The handle 120 is set to a dimension that does not contact the operation switches around the twist type operation switch to be operated. Specifically, the length of the socket part 110 is such that the handle part 120 and the handle part 120 are gripped when the switch operation adapter 100 is attached to a twisting type operation switch to be operated. The dimensions are set so that the operator's hand and fingers do not touch the operation switches around the twist type operation switch to be operated.

  A twist type operation switch is provided on a control panel (see reference numeral 610 in FIGS. 6 and 7) and the like, for example, by twisting around an axis such as a dial, the connection state of an electric circuit is changed. Switch. Specifically, the twist type operation switch includes, for example, a shaft portion attached to the control panel and a handle provided at the tip of the shaft portion. Such a twisting type operation switch has a substantially L shape by a shaft portion (see reference numeral 601 in FIGS. 6 and 7) and a handle (see reference numeral 602 in FIGS. 6 and 7).

  A plurality of twist type operation switches are arranged side by side in a control panel for remotely operating electrical equipment (field equipment) installed in each substation. The control panel is installed at a control station that is different from the site where the site equipment is installed and is separated from the site. The control panel includes a twist type operation switch, and various operation switches for remotely operating the field equipment are provided. The various operation switches including the twist type operation switch are provided in the same number as the number of field devices to be remotely operated and the number of locations to be remotely operated in the field devices.

  In recent years, the number of switches provided on the control panel has increased with the increase in the number of field devices to be remotely operated and the number of locations to be remotely operated in the field devices. For this reason, as the number of switches increases, the size of each switch provided on the control panel is reduced and the interval between the operation switches is narrower than that of the conventional switch. By reducing the size of each switch and reducing the interval between the operation switches, the control panel can be reduced in size.

  The handle portion 120 has a substantially spindle shape (rugby ball shape). The handle portion 120 has a cylindrical shape, and has a shape with a thick central portion and gradually narrowing at both ends. The socket part 110 and the handle part 120 are connected to each other at a position eccentric from the central part in the longitudinal direction of the handle part 120. The socket part 110 and the handle part 120 can be molded integrally. The socket part 110 and the handle part 120 may be formed separately and connected by bonding or the like.

  The handle 120 is not limited to a smooth surface, and may be provided with irregularities. The unevenness can be realized, for example, by a depression provided in a portion where the operator's finger contacts when the switch operation adapter 100 is used. Further, the unevenness may be provided in a shape along the finger, for example, at a portion where the operator's finger contacts when the switch operation adapter 100 is used.

  FIG. 2 is an explanatory diagram showing dimensions of each part in the switch operation adapter 100 according to the first embodiment of the present invention. In FIG. 2, the symbol A indicates the dimension of the handle portion 120 in the length direction. Specifically, the dimension A in the length direction of the handle 120 is preferably about 80 mm, for example.

  In FIG. 2, the symbol B indicates the dimension at the maximum portion of the dimension (diameter) in the thickness direction of the handle part 120.

  In FIG. 2, the symbol D indicates the dimension (diameter) of the socket part 110 in the thickness direction. The dimension (diameter) D in the thickness direction of the socket part 110 can be set to, for example, about 27 mm. Since the recess 111 opens toward the outer peripheral surface of the socket part 110, the dimension (diameter) D in the thickness direction of the socket part 110 is based on the length dimension of the handle in the twist type operation switch to be operated. Can also be reduced. Thereby, size reduction of the adapter 100 for switch operation can be achieved.

  As described above, since the socket part 110 and the handle part 120 are connected at a position eccentric from the central part in the longitudinal direction of the handle part 120, the dimension indicated by reference sign E and the dimension indicated by reference sign F in FIG. Is different. Specifically, the portion indicated by the symbol E in FIG. 2 is preferably about 20 mm, for example. In this case, the portion indicated by the symbol F in FIG. 2 is about 33 mm.

As shown in FIG. 3, the dimension G in the width direction of the socket part 110 is smaller than the dimension B in the thickness direction at the maximum part of the handle part 120. By making the dimension G in the width direction of the socket part 110 smaller than the dimension B in the thickness direction at the maximum part of the handle part 120, the operator can easily grasp and feel a sense of stability when grasping. Can be given. Thereby, the operator can operate an operation switch reliably. The recess 111 is provided at a substantially central portion of the socket part 110 in the diameter direction of the socket part 110.

  FIG. 4 is an explanatory diagram showing dimensions of each part in the switch operation adapter 100 according to the first embodiment of the present invention. 4 shows a state in which the socket part 110 is viewed from the front end side of the socket part 110 along the length direction of the socket part 110. FIG. In FIG. 4, the symbol H indicates the dimension of the maximum position of the concave portion 111 having a tapered shape in a plane orthogonal to the axial direction of the socket portion 110. Specifically, the dimension H is preferably about 20 mm, for example. In FIG. 4, the symbol I indicates the size of the minimum position of the concave portion 111 having a tapered shape on a plane orthogonal to the axial direction of the socket portion 110. Specifically, the dimension I is preferably about 10 mm, for example.

  FIG. 5 is an explanatory view showing dimensions of each part in the switch operation adapter 100 according to the first embodiment of the present invention. FIG. 5 shows a cross section of the socket part 110 cut along a plane passing through the axis of the socket part 110 and parallel to the axis. In FIG. 5, the symbol J indicates the dimension of the maximum position of the concave portion 111 having a tapered shape in a plane parallel to the axial direction of the socket portion 110. Specifically, the dimension J is preferably about 20 mm, for example. In FIG. 5, the symbol K indicates the dimension of the minimum position of the concave portion 111 having a tapered shape in a plane parallel to the axial direction of the socket portion 110. Specifically, the dimension K is preferably about 10 mm, for example.

  6 and 7 are explanatory views showing an example of use of the switch operation adapter 100. FIG. For example, as shown in FIG. 6, the switch operation adapter 100 is used by being gripped by an operator's hand 620. In this way, by holding the switch operation adapter 100 with the operator's hand 620, the contact between the twist type operation switch 600 and the switch operation adapter 100 is used as a fulcrum, and the principle of leverage is used. The shaft portion 601 of the rotary operation switch 600 can be reliably rotated with a small force. Thereby, the twist type operation switch 600 can be easily and reliably operated.

  Further, the switch operation adapter 100 can be used by being gripped by the operator's hand 620 as shown in FIG. 7, for example. In this case, the operator separates the second finger and the third to fifth fingers with the socket portion 110 therebetween, and uses the second finger while holding the second finger hooked on the tip of the switch operation adapter 100. By gripping in this way, the twist type operation switch 600 and the switch operation adapter 100 can be reliably engaged, and a rotational force can be applied to the twist type operation switch 600 more reliably.
