Description

  The present invention relates to an attachment / detachment / replacement device for a straight tube fluorescent lamp in which a base is brought into contact with a spring-displaceable socket accommodated in a socket case, and a base pin is inserted into a terminal hole of the socket to be electrically connected.

  As a straight tube type fluorescent lamp, the sockets on both sides are accommodated in socket cases so that they can be spring-displaced, and the cap pins on both sides are inserted into the terminal holes of each socket, and the caps are brought into contact with the sockets to be installed as a crossover. There is something.

  In the case of the fluorescent lamp, since the socket on one side is immersed in the socket case, the other base (including “base pin”, the same hereinafter) is separated from the opposite socket (including “terminal hole”, hereinafter the same). The entire lamp is removed, or the other base is attached together with the opposite socket so that it can be attached and detached.

  In order to support the attachment and detachment and replacement of fluorescent lamps installed in relatively high places such as the ceiling, conventionally, there is a long handle bar that can be extended to high places, and a chuck that can hold or release the glass tube of fluorescent lamps. A fluorescent lamp attachment / detachment exchange fixture that is attached and fixed to the tip end of the handle bar, and has a movable claw that can be displaced laterally in the axial direction by holding the fluorescent lamp base, and is attached to the tip side of the handle bar that is spaced from the chuck. Is known (patent documents 1 and 2).

  Separately, instead of the above-mentioned movable claw, the engaging piece that can be pressed from the end face of the base is inserted into the gap between the base and the socket so as to laterally shift the entire lamp in the axial direction. An attaching / detaching / changing device for a fluorescent lamp is also known (Patent Documents 3 and 4).

  The fluorescent lamp attachment / detachment / replacement device will be explained when the fluorescent lamp is removed. In either case, the fluorescent lamp glass tube is gripped by the chuck, and the entire lamp is fed to the chuck side with a movable claw or engagement piece. It is configured to In other words, the entire lamp is pushed by the movable claw or the movable side of the engaging piece with respect to the grip (fixed point) of the glass tube by the chuck.

  According to this, if the glass tube is not gently gripped by the chuck so that the entire lamp is pushed and fed by the movable claw or engaging piece, the stress caused by the pressing of the movable claw or engaging piece Will be added to the glass tube between the chuck. For this reason, it is necessary to provide a chuck capable of stably holding the glass tube and gently holding the glass tube so as to be relatively displaced.

  In addition to the above, a support base made of a leaf spring bent into a substantially trapezoidal shape is attached to the distal end side of the handle bar, and a hook-shaped clip is interposed inside the support base, and the clip and the support base are relative to each other with a support shaft. Is attached to the gripping part of the handle bar, and a projecting arm with a substantially L-shape is attached to the lower side of the support base. There is known a fluorescent lamp attaching / detaching / changing device that is attached to a side surface of a handle bar by a support shaft so as to extend from a socket case to a socket case (Patent Document 5).

  The fluorescent lamp mounting / dismounting apparatus will be described when the fluorescent lamp is removed. First, the clip is half-opened and applied to the glass tube, and the handle bar extends from the pivot point of the clip to the support base. Keep the slant arm in the opposite direction, place the strut arm on the socket case on one side, hold the glass tube with a clip, and then move the handle bar vertically to socket the strut arm Since the lever is brought into pressure contact with the case, the entire lamp can be moved in the axial direction by a clip holding the glass tube so that the base can be removed from the socket.

In the fluorescent lamp attaching / detaching / replacement device, as described above, the clip is applied to the glass tube in a half-opened state, and the axis of the handle bar is held obliquely so that the tip end of the tension arm is applied to the socket case on one side. It takes a lot of work. In addition, it is necessary to perform an unreasonable work of removing the entire lamp from the socket by rubbing it from the socket case while the lever arm is in a state of being pressed against the socket case.

The chuck is formed in a substantially U-shape by bending the right and left vertical axis portions at right angles from the horizontal axis portion at the center of the tip, and the middle sides of both vertical axis portions are curved in an arc shape in the same direction. Two pairs of gripping frames bent back in a substantially perpendicular direction in the same direction as the arc direction with the lower axis side as the base axis part from both longitudinal axis parts are bent diagonally upward in the opposite direction to the arc direction.
Each base shaft is inserted into the cylinder through a locking hole opened on each side surface of the cross beam frame, and both gripping frames are opposed to both sides of the horizontal beam frame and are arranged in the cylinder of the cross beam frame. Pull each spring end of the tension spring outward from the through hole that opens on each side surface of the cross beam frame, and hang it under the axis of the opposite vertical axis of both gripping frames,
With the base shaft part inserted into the cylinder through the locking hole of the cross beam frame as a fulcrum, both gripping frames are supported by a tension spring so as to be separated or close to each other, and the ends of both vertical axis parts are used as glass tube receiving ports. the middle side of the vertical axis portion, characterized in that the assembly as a clamping portion of the glass tube.

According to claim 2 of the present application, the bottom portion of the chuck is disposed on the lower side of the cross beam frame, each side portion is disposed on both sides of the cross beam frame, and the tip side of each side portion is disposed on the cross beam frame. An upward U-shaped wedge-shaped piece that can be interrupted between the side surface of each gripping frame and the bridging shaft portion of each gripping frame, and planted in the bottom of the wedge-shaped piece and inserted into the cylinder of the cross beam frame , Consisting of a detachable pin that exposes the heel head on the upper surface of the cross frame facing the gripping frame,
The removal pin protrudes from the upper surface of the cross beam frame facing the gripping frame, and each side portion of the wedge-shaped frame is inserted between the side surface of the cross beam frame and the bridging shaft portion of each gripping frame. The holding frame is separated and held, and the wedge-shaped frame is pushed down by the glass tube of the fluorescent lamp that is received between the held holding frames to push the wedge-shaped frame to the side surface of the cross beam frame and the bridging shaft portion of each holding frame. It is characterized by a key that can be taken out from between.

  Claim 3 of the present application includes an operating rod installed in the center, a transverse beam frame extending in both directions facing the glass tube of the fluorescent lamp from the operating rod, and the chucks are respectively disposed on both side portions of the transverse beam frame. It is characterized by.

  Claim 4 of the present application is characterized in that an anti-slip elastic pad is stretched on the upper surface of the cross beam frame facing the glass tube of the fluorescent lamp.

  In the straight tube type fluorescent lamp attaching / detaching / replacement device according to claim 1 of the present application, when removing the fluorescent lamp, the operator lifts the entire tool with the operating rod to the place where the fluorescent lamp is installed, and first pushes the tip of the pusher. When the entire tool is pushed up using the socket case on one side as a reference surface, the chuck accepts and holds the fluorescent glass tube between the holding frames, and the pusher removes the cap from the fluorescent tube glass tube. Accept freely in contact. Next, when the operator pivots the operating rod, the pusher is pushed in an extending direction from one end of the cross beam frame by the eccentric cam, and the cross beam frame contacts the socket case while holding the glass tube of the fluorescent lamp with the chuck. Because it moves relative to the pusher in contact with it, the socket on the other side is immersed inside the socket case through the entire fluorescent lamp, and at the same time, the entire lamp is separated from the socket on the pusher side to include the cap pin. The base can be removed from the socket. When the base is removed, the base including the base pin on the other side remains held by the socket on the other side, but if the operator pulls down the entire tool with the operation rod, the pusher is in contact with the socket case. Remove the base including the base pin from the socket on the pusher side while holding the crow tube of the fluorescent lamp with the chuck, and take the entire lamp diagonally downward from the socket case. Also, connect the base including the base pin on the other side. Since it can be removed from the socket on the side, the fluorescent lamp held by the chuck can be pulled to the hand with the operating rod.

  When attaching the fluorescent lamp, first, the pusher and the base on one side are aligned with each other on the end face of the reference surface, and the glass tube of the fluorescent lamp is held by the chuck, so that the fluorescent lamp is assembled to the cross beam frame. Next, the worker holds the operating rod and lifts the fluorescent lamp to the installation location, aligns the cap on one side and the corresponding socket, and inserts the cap pin into the terminal hole. When the cap pin on one side is inserted into the terminal hole, the tip end of the pusher is slightly inclined to the socket case on one side. When the operator pivots the operating rod from this pusher applied state, the pusher is pushed in the extending direction from one end of the cross beam frame by the eccentric cam as described above, and the cross beam frame is moved to the glass tube of the fluorescent lamp. Because the socket that is inserted into the terminal hole through the whole lamp of the fluorescent lamp is inserted into the socket case through the relative movement of the pusher that is in contact with the socket case while being held by the chuck, The base on the pusher side can be aligned with the socket on that side. When the pusher base is aligned with the socket on that side, when the operator pivots the operating rod in the reverse direction, the pusher is released from pushing by the eccentric cam, so the previous cap pin is inserted into the terminal hole. At the same time that the socket is pushed out inside the socket case, the cap pin on the pusher side can be inserted into the terminal hole of the socket on that side. As a result, the fluorescent lamp can be attached to the equipment location, and if the operator pulls down the entire tool with the operation rod, the chuck can be removed from the glass tube of the fluorescent lamp.

  When attaching or removing the fluorescent lamp, the chuck does not rub against the glass tube of the fluorescent lamp, and the pusher does not slide on the glass tube of the fluorescent lamp, so stress is not applied to the glass tube. Thus, the fluorescent lamp can be easily attached and detached with a simple operation.

When attaching and detaching , the holding frames are supported on both sides of the cross beam frame by a tension spring so as to be separated or close to each other, and the ends of both vertical axis portions are warped obliquely upward to form a glass tube receiving port. Since the chucks of the two pairs of gripping frames which are formed by sandwiching the middle abdominal sides of the two vertical axis portions and used as the glass tube clamping portion are assembled, the glass tube of the fluorescent lamp can be stably held by the chuck.

  In the straight tube type fluorescent lamp attaching / detaching / replacement apparatus according to claim 2 of the present application, the removal pin is protruded from the upper surface of the opposite cross beam frame of the gripping frame so that each side of the wedge-shaped frame is a side surface of the cross beam frame. And hold the gripping frame apart from each other, and when removing the fluorescent lamp, push the removal pin down with the glass tube of the fluorescent lamp that is received between the gripping frames held separately. Since the wedge-shaped frame is assembled with a key that can be moved out between the side surface of the cross beam frame and the bridging shaft of each gripping frame, it is easy to chuck even fluorescent lamps installed in relatively high places such as the ceiling. And it can be surely held.

  In the straight tube type fluorescent lamp attaching / detaching / replacement device according to claim 3 of the present application, the operation rod is installed in the center, and is provided with a cross beam frame extending in both directions facing the glass tube of the fluorescent lamp from the operation rod. Since they are respectively arranged on the side portions near the both ends of the frame, it is possible to hold the operation rod and hold the long straight tube fluorescent lamp stably with the chuck.

  In the straight tube type fluorescent lamp attaching / detaching / replacement device according to claim 4 of the present application, the elastic pad for preventing slipping is stretched on the upper surface of the cross beam frame facing the glass tube of the fluorescent lamp.
