Description

  The present invention relates to a power switching device of an opening and closing device having an opening and closing member which is openable and closable, and, for example, a shutter device whose opening and closing member is a shutter curtain and an opening and closing body which slides It can be used for various opening / closing devices such as over-sliding door (overhead door) devices, smoke-proof hanging wall devices, sliding door devices and the like.

  In Patent Document 1 listed below, a shutter curtain 50 (see FIG. 2), which is an open / close member that is openable and closable, and an open / close machine M (FIG. 1 and FIG. 2), a commercial power supply AC (see FIG. 2) which is a first power supply for supplying power to at least the switching machine M at normal times, and at least power for supplying power to the switching machine M at the time of emergency when a power failure occurs. A switchgear configured to include an emergency power supply 45 which is a second power supply, and an emergency switch 46 (see FIG. 3) which is a changeover switch for switching from the commercial power supply AC to the emergency power supply 45 at least in an emergency. A power supply switching device of the shutter device is shown.

JP-A-9-287371

  By the way, when the switch of the power supply switching device described above is operated by a human, that is, when it is a manual type, when the power failure is recovered, the switch of the power supply switching device is operated. It is preferable to immediately switch the power source for supplying power to the switchgear M or the like from the emergency power source 45 to the commercial power source AC.

  Here, the manual changeover switch described above is housed and arranged inside a housing member having an opening which can be opened and closed by a lid member, and the lid member can be pivoted about a hinge. If there is an emergency, the administrator of the shutter device opens the cover member in the fully closed state, and then operates the changeover switch to use a commercial power supply for supplying power to the open / close machine M etc. The power supply AC is switched to the emergency power supply 45.

  After that, when the lid member is closed and the shutter is fully closed again, the administrator of the shutter device who performed the power supply switching operation operates the changeover switch to supply power when the power failure is restored. There is a risk of forgetting to switch the power supply from the emergency power supply 45 to the commercial power supply AC.

  This is because when the administrator of the shutter device closes the lid member after the power switching operation and makes the shutter fully closed again, it is impossible to know from the outside what the state of the changeover switch is. It is.

  Therefore, there is a need for a device for remembering to switch the power source for supplying power by operating the changeover switch from the emergency power source 45 to the commercial power source AC when the power failure is recovered.

  An object of the present invention is a switchgear which can prevent forgetting to switch a power source for supplying power by operating a changeover switch from a second power source to a first power source when a power failure is recovered. To provide a power switching device.

  A power supply switching device of a switching device according to the present invention includes: a switching member which is openable and closable; a driving device for driving the switching member; and a first power supply for supplying power to the driving device at a normal time. And a second power supply for supplying power to the drive device in an emergency, and a changeover switch for switching from the first power supply to the second power supply in the emergency case. In the device, the change-over switch has an operating portion that is rotatable in one of the vertical direction and the lateral direction, and the operating portion is rotated to one rotation limit position. The power from the first power supply is supplied, and the power from the second power supply is supplied by rotating the operation unit to the other rotation limit position, and the changeover switch has a lid Opening and closing by members And the lid member is pivotable about a hinge, and the back surface of the lid member is disposed to be opposed to the opening portion. And the cover member is prevented from closing to the fully closed position when the operating unit being operated is at a position from the center position to the other rotation limit position within the rotating range of the operating unit A cover member full closing operation preventing means is provided.

  In the present invention, the change-over switch has the operation portion which is rotatable in one of the vertical direction and the left and right direction, and the operation portion is rotated to one rotation limit position. Power from the first power supply is supplied, and power from the second power supply is supplied by rotating the operation unit to the other rotation limit position.

  In other words, one rotation limit position of the rotation range of the operation portion of the changeover switch is a position where power from the first power source is supplied, and the other rotation limit position is the second position. It is a position where power from the power supply is supplied.

  Further, in the present invention, the changeover switch is housed and arranged inside a housing member having an opening that is openable and closable by a lid member, and the lid member is pivotable around a hinge. The pivoting direction of the lid member may be left-right or up-down.

  And in the present invention, on the back surface of the lid member, the operation portion of the changeover switch disposed opposite to the opening of the storage member is at the central position (the operation portion is horizontal) within the rotation range of the operation portion. A cover member full closing operation blocking means is provided to block the closing operation of the cover member to the fully closed position when in the position from the posture position) to the other rotation limit position.

  That is, in the present invention, when the operation part of the changeover switch is at the position from the center position to the other rotation limit position, the lid member may be closed to the fully closed position (in other words, it is turned to the closing side) Even if it is made to operate, this lid member will stop the closing operation at a position before the fully closed position.

  For this reason, according to the present invention, switching the power supply for supplying power by operating the changeover switch from the second power supply to the first power supply, in other words, forgetting to return the changeover switch to the normal position It can be prevented.

When the operation unit is at a position closer to the other rotation limit position than the central position (except for the other rotation limit position), in other words, it is closer to the other rotation limit position than the central position. When in the position from the position to the position just before the other rotation limit position, the operating portion may or may not rotate to the other rotation limit position by the lid member which has been closed. .

  When the operation unit is at a position closer to one pivot limit position than the central position (including one pivot limit position), in other words, the side of one pivot limit position than the central position The lid member can be closed to the fully closed position when in the position from the position of 1 to the position of one rotation limit.

  In addition, when the operation unit is at a position closer to one rotation limit position than the central position (except for one rotation limit position), in other words, the side of one rotation limit position than the center position The operating portion may or may not be pivoted to one pivot limit position by the closing member when it is in the position from the position above to the position immediately before the one pivot limit position. Good.

  In the present invention, the operation portion of the changeover switch is rotatable in the vertical direction, and the operation portion is moved to one rotation limit position on the upper side (in other words, up) of the rotation limit position. By rotating, the power from the first power source is supplied, and the second operation is performed by rotating the operation unit to the other rotation limit position on the lower side (in other words, downward direction). When power is supplied from the power supply, the cover member fully closing operation preventing means is in the fully closed position when the operation unit is at the position from the central position to the lower rotation limit position. It will prevent the closing operation.

  In addition, in the case where the operation portion of the changeover switch is rotatable in the vertical direction, the first operation portion is rotated to the lower rotation limit position which is one rotation limit position. In the case where power from the second power supply is supplied by supplying power from the power supply and rotating the operation unit to the upper rotation limit position, which is the other rotation limit position, the lid The member fully closing prevention means prevents the lid member from closing to the fully closed position when the operating portion is in the position from the central position to the upper pivot limit position.

  On the other hand, in the present invention, in the case where the operation portion of the changeover switch is rotatable in the left and right direction, the rotation limit position of the left side (in other words, left direction) which is one rotation limit position of the operation portion. Power is supplied from the first power supply by turning the power supply to the second power supply, and the second rotation limit position of the second operation limit is set to the second rotation limit position. When power from the power supply is supplied, the cover member fully closing operation preventing means moves the cover member to the fully closed position when the operation unit is at the position from the central position to the right rotation limit position. It will prevent the closing operation.

  Also, in the case where the operation portion of the changeover switch is rotatable in the left and right direction, the operation portion is pivoted to the pivot limit position on the right side (in other words, right direction) which is one pivot limit position. Power from the first power supply is supplied, and the operation unit is rotated to the rotation limit position on the left side (in other words, the left direction), which is the other rotation limit position, from the second power supply. In the case where power is supplied, the lid member fully closing operation blocking means closes the lid member to the fully closed position when the operation portion is at the position from the central position to the left rotation limit position. It will be something to prevent that.

  In the present invention described above, the type, structure, etc. of the changeover switch may be arbitrary as long as the first power supply and the second power supply can be switched between each other. For example, the changeover switch operates vertically. It may or may not have a part.

  As a changeover switch in the former case, for example, a knife switch, a toggle switch (where the operation unit moves up and down), a rocker switch, etc. can be mentioned, and as a changeover switch in the latter case, for example, a rotary switch, a selector The switch, the toggle switch (the operation unit moves in the left and right direction), the push button switch, and the like can be mentioned.

  In the present invention, the type and structure of the lid member fully closing operation blocking means is such that the operation portion disposed opposite to the opening portion is at the other rotation limit position from the central position within the rotation range of the operation portion. When in the up position, it may be anything as long as it prevents the lid member from closing to the fully closed position.

  In the present invention, as described above, the operation portion of the changeover switch is rotatable in the vertical direction, and the operation portion is rotated to the upper rotation limit position to obtain the first power source. In the case where power from the second power source is supplied by supplying power from the second power source and rotating the operation unit to the lower rotation limit position, the type and structure of the changeover switch is, for example, the opening The cover portion has a semicircular portion on the side of the portion, and the operation portion protrudes from a groove formed in the circumferential direction of the outer peripheral surface of the semicircular portion and is guided by the groove. It may or may not be rotatable in the vertical direction.

  In the former case, as an example of the type and structure of the lid member fully closed movement preventing means, it is a projecting member arranged to protrude from the back surface of the lid member to the storage member side, and this projecting member is a semicircular portion of the cover member Has a shape substantially corresponding to the outer peripheral surface of the housing and has a recess opened to the storage member side, and the end surface on the storage member side in the portion below the recess is a storage member in the portion above the recess What protrudes to the storage member side by the same or substantially the same dimension as the dimension in the thickness direction, which is the rotational direction of the operation part, can be mentioned from the end face on the side.

  In this example, when the operating part is in the upper rotation limit position before the closing operation of the closing member, the closing member moves to the full closing position when closing the closing member. The entire recess of the projecting member disposed on the back surface of the lid member is in contact (in other words, in close contact) with the outer peripheral surface of the semicircular portion of the cover member of the changeover switch. The end surface on the side of the storage member in the portion is in a state of being in contact with the portion on the opening side of the operation portion at the upper rotation limit position.

  Moreover, in this example, when the operation part is at the lower rotation limit position from before closing the lid member, when the lid member is closed, the portion lower than the recess of the projecting member is The lid member stops the closing operation before the fully closed position when the end face on the storage member side abuts on the opening side portion of the operation part at the lower rotation limit position, and at this time, The entire recess of the projecting member disposed on the back surface of the lid member is not in contact with the outer peripheral surface of the semicircular portion of the cover member of the changeover switch.

  Further, in this example, when the operating portion is at the central position from before the closing operation of the lid, the recess of the projecting member abuts on the tip of the operating portion when the closing operation is performed. The lid member stops the closing operation before (in other words, immediately before) the fully closed position. At this time, the entire recess of the projecting member disposed on the back surface of the lid member is not in contact with the outer peripheral surface of the semicircular portion of the cover member of the changeover switch.

  In this example, when the operation unit is at a position on the side of the pivot limit position above the central position before closing the lid member (except for the upper pivot limit position), the lid member is closed. As it is operated, the operating portion abuts on the projecting member and is pushed up by the projecting member and pivoted to the upper rotation limit position, at which time the lid member is as described above. , Closed to the fully closed position.

  Further, in this example, when the operation unit is at a position on the side of the rotation limit position lower than the central position before the closing operation of the lid member (excluding the rotation limit position on the lower side), the lid member When the closing operation is performed, the operating portion abuts on the projecting member and is pushed down by the projecting member to pivot to the lower rotation limit position. At this time, the lid member is As described above, the closing operation is performed up to (in other words, immediately before) the fully closed position.

  In this example, the lid member fully closing operation preventing means may not be a projecting member separate from the lid member, but may be a projecting portion integrated with the lid member.

  In the present invention, the type and structure of the housing member in which the changeover switch is housed and arranged may be arbitrary, and the housing member may be, for example, a guide member for guiding the opening / closing movement of the opening / closing body A dedicated case member (in other words, a storage box) or the like may be used for storing and arranging the changeover switch (including other parts constituting the power supply switching device) inside.

  In the former case, when the guide members are disposed on both sides in the width direction of the opening and closing body, the changeover switch is the right side of the left and right guiding members disposed on both sides in the width direction of the opening and closing body. It may be housed and arranged inside the guiding member, or it may be housed and arranged inside the guiding member on the left side.

  In the former case, the lid member may be a right-opening door or a left-opening door. The door may be an open door pivotable about a hinge or a sliding door, but in the case of a sliding door, a space for a door bag is required, so the door is preferably an open door.

  When the lid member is a left-open door, when the lid member is opened to perform the power switching operation or the maintenance operation of the power switching device, the administrator of the opening / closing device is opened and exists on the left side. It may be necessary to work in a tight space between the cover member and the building frame such as the wall present on the right side. For this reason, it is more preferable that the lid member is a right opening door, considering that there are many right-handed people.

  In consideration of the above, when the guide members are disposed on both sides in the width direction of the opening and closing body, the changeover switch is one of the left and right guiding members disposed on both sides in the width direction of the opening and closing body It is more preferable to store and arrange the inside of the guide member on the right side, and to set the lid member as a right-opening door.

  In the present invention, in the case where the storage member for storing and arranging the changeover switch inside is the guide member for guiding the opening and closing movement of the opening and closing body as described above, the changeover switch has the same cross-sectional shape but is long It may or may not be housed and disposed inside the guide member directly or further via the mounting member via a seat member having a hat-shaped cross section which is continuous in the direction.

  In the former case, the type and structure of the base member may be arbitrary, and one example is that the cross-sectional shape of the base member is open from the flat portion where the changeover switch is disposed and both ends in the width direction of this flat portion It consists of left and right first bends bent 90 degrees to the side opposite to the part side, and left and right second bends bent 90 degrees outward from the tip of each first bend. It is a thing.

  In this example, on the lower side of the flat portion (in other words, the upper surface portion or the horizontal portion) of the base member, a space portion is formed by the flat portion and the first bending portion on the left and right (in other words, the hanging portion). Therefore, this space portion can be used as a wiring space of components of the power supply switching device including the changeover switch (in other words, a space for arranging a power supply line or the like).

  When the power supply switching device is provided with an outlet into which the power supply plug of the second power supply is inserted, the outlet may be disposed on the flat portion of the pedestal member and integrated with the changeover switch. It does not have to be.

  According to the former case, the changeover switch and the outlet can be assembled in advance in the factory in an integrated form, and at the site where the switchgear is installed, the factory integrated changeover switch and You only have to do the work of arranging the outlet.

  That is, this makes the operation of storing and arranging the changeover switch and the outlet socket inside the guide member and the operation of removing the guide member from the inside thereof easier as compared with the case where they are not integrated.

  Here, integrating the changeover switch and the outlet means, for example, placing and fixing (in other words, placing) the changeover switch and the outlet on the upper surface portion of the pedestal member.

  The longitudinal direction of the base member when stored and arranged inside the guide member may be the vertical direction or the horizontal direction.

  In the latter case, it is necessary to increase the dimension in the width direction (in other words, the direction orthogonal to the opening / closing movement direction of the opening / closing body) which is the left / right direction of the guiding member compared to the former case. It is preferable that the longitudinal direction of the base member when stored and disposed inside the upper and lower directions be the vertical direction.

  In the case where the longitudinal direction of the base member when stored and arranged inside the guide member is the vertical direction, the changeover switch and the outlet may be arranged vertically in the order of the changeover switch and the outlet from above, from above The outlet and the changeover switch may be arranged vertically in this order.

  Here, when the second power supply is disposed on a floor or the like, in an emergency, a power plug that is the tip of a power supply line (in other words, an electrical cord) extending from the second power supply is used. , Will plug into the outlet.

  Therefore, in the case where the changeover switch and the outlet are vertically arranged in order from above, the length of the power supply line extended from the second power supply is shorter than in the case where the outlet and the changeover switch are arranged vertically in order can do.

  The components of the power supply switching device other than the changeover switch and the outlet may or may not be disposed on the flat portion of the base member to be integrated with the changeover switch and the outlet.

  In the present invention, the type, structure, etc. of the guide member may be arbitrary. For example, the guide member accommodates the insertion portion into which the end in the width direction of the opening / closing body is slidably inserted, and at least the changeover switch and the outlet The storage unit may be configured to include.

  In this example, the insertion portion and the storage portion may or may not be partitioned by the partitioning portion.

  According to the former case, even if dust, rain water, etc. may flow from the insertion portion, they are blocked by the partition portion and prevented from flowing into the storage portion. That is, according to this, it is possible to protect the changeover switch, the outlet, and the like stored in the storage portion from the outside.

  The guide member may be formed of only an insertion portion into which the end in the width direction of the opening / closing body is slidably inserted, and at least the changeover switch and the outlet may be accommodated and disposed in the insertion portion.

  In the above invention, the first power source may be a commercial power source, or may be a generator capable of long-term power supply (for example, a diesel generator, a gasoline generator, a solar power generator, a wind power generator, etc.) . On the other hand, the second power source may be a storage battery (in other words, a battery), and may be the above-mentioned generator (it is not always necessary to be able to supply power for a long time).

  In the present invention, the second power source may or may not be movable.

  According to the former case, normally, the second power supply is stored in a place (for example, a storeroom, a warehouse, etc.) other than the installation place of the switchgear, and in an emergency, the installation place of the switchgear Operation to move up to is possible.

  As a result, since it is not necessary to always provide the second power supply inside or in the vicinity of the switchgear, the installation cost of the second power supply can also be reduced.

  In particular, when a plurality of switchgears are installed in the field, it is not necessary to always prepare a second power supply dedicated to each switchgear in or near each switchgear, and there are a plurality of switchgears. It becomes possible to share (in other words, reuse) one second power supply by the switchgear of the above. As a result, the installation cost of the second power supply can be significantly reduced.

  In the latter case (when the second power supply is not movable), if the second power supply has a shape and dimensions that can be accommodated and disposed inside the guide member, the second power supply is You may make it store and arrange inside a guide member with a changeover switch, an outlet socket, etc.

  In addition, it is preferable to arrange the changeover switch at a height position where a person who performs the switching operation of the power supply can easily operate. For example, it is preferable to arrange the changeover switch at a height of about 130 cm from the floor or the ground.

  In the present invention, in the case where a plurality of opening / closing devices are installed at the site, the changeover switch may or may not be provided for each of the opening / closing devices.

  According to the latter case, only one switching switch may be provided, and it is possible to switch the power supply of all the switching devices by operating the one switching switch.

  The present invention relates to a shutter device having a shutter curtain as an opening and closing member, an oversliding door (overhead door) device having a sliding door as an opening and closing member, a smokeproof drip wall device, a sliding door device and the like. Applicable to

  Note that the shutter device may be a management shutter device in which the shutter curtain moves open and closed and movement is stopped by the operation of the operation device described above, or a disaster prevention shutter device forming a disaster prevention section by the fully closed shutter curtain Alternatively, a shutter device for both management and disaster prevention may be used, and further, a garage shutter device, a window shutter device, and the like may be used.

  In the power supply switching device of the opening and closing device according to the present invention, the lid member is prevented from closing to the fully closed position only when the operation part of the changeover switch is at the central position where the horizontal posture is set. It is also good.

  In order to achieve such an action, for example, when the operation portion of the changeover switch is at the center position, the operation portion projects from the opening surface of the opening of the storage member (in other words, protrudes). May be arranged in the storage member.

  For example, a spacer may be disposed between the changeover switch and the housing member to adjust the distance therebetween.

  According to the present invention, it is possible to prevent forgetting to switch from the second power supply to the first power supply by operating the switch of the power supply switching device of the switchgear to supply power when the power failure is recovered. You will get the effect of being able to
