Abstract
Abstract An apparatus for recharging a storage battery employed in a self-running vehicle, for example, a cart, a carrier or the like for transporting loads. The recharging is carried out without interrupting the loading, unloading or transporting work. A plug means and a socket means are securely connected by some specific means and never disconnected from each other during the recharging process. According to the present invention, there can be obtained a high recharging effect and elimination of loss of time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
233 words
An apparatus for recharging a self-running vehicle for loading and/or unloading a working machine, employing as a power source a storage battery, comprising a socket means attached to the self-running vehicle; a plug means adapted to be connected with said socket means; a rail adapted to move up and down to connect and disconnect said socket means with said plug means, respectively, said plug means being adapted to reciprocatingly travel on said rail; an actuating means for actuating said rail to move up and down; a detecting means for detecting arrival of the self-running vehicle at a predetermined position to start recharging and for transmitting a signal; a signal receiving means for receiving said signal to operate said actuating means to move said rail up to connect said socket means with said plug means; a recharging means connected to said plug means for recharging said storage battery; said signal receiving means being adapted to receive a signal from another detecting means for detecting the completion of the loading and/or unloading after recharging and to operate said actuating means to move said rail down to disconnect said plug means from said socket means; and a means for returning said plug means to a starting position; said plug means, said rail, said actuating means, said detecting means and said means for returning the plug means being attached to a frame connected to said working machine.
Claim 2
Independent Claim
233 words
An apparatus for recharging a self-running vehicle for loading and/or unloading a working machine, employing as a power source a storage battery, comprising a socket means attached to the self-running vehicle; a plug means adapted to be connected with said socket means; a rail adapted to move up and down to connect and disconnect said socket means with said plug means, respectively, said plug means being adapted to reciprocatingly travel on said rail; an actuating means for actuating said rail to move up and down; a detecting means for detecting arrival of the self-running vehicle at a predetermined position to start recharging and for transmitting a signal; a signal receiving means for receiving said signal to operate said actuating means to move said rail up to connect said socket means with said plug means; a recharging means connected to said plug means for recharging said storage battery; said signal receiving means being adapted to receive a signal from another detecting means for detecting the completion of the loading and/or unloading after recharging and to operate said actuating means to move said rail down to disconnect said plug means from said socket means; and a means for returning said plug means to a starting position; said plug means, said rail, said actuating means, said detecting means and said means for returning the plug means being attached to a frame connected to said working machine.
Claim 3
Dependent Claim
16 words
An apparatus as claimed in claim 1, wherein said actuating means is a fluid pressure-operated means.
Claim 4
Dependent Claim
28 words
An apparatus as claimed in claim 1, wherein said recharging means is adapted to operate through a timer means for recharging the storage battery for a predetermined time.
Claim 5
Dependent Claim
32 words
An apparatus as claimed in claim 2, wherein said self-running vehicle is slidably connected with said frame through a roller fixed to said vehicle and a guide rail fixed to said frame.
