Abstract

In a holder and a structure for organizing excess length by winding cables and the like, an excess length organizing holder comprises a baseboard which has a rotation axis vertical to a fixed plane, and a spool which has a flange whose edge is provided with two incisions and a winding portion. The spool is rotated around the rotation axis in a state where a cable is folded by way of the winding portion and the two incisions, thereby winding the cable twofold around the winding portion. Also, an excess length organizing structure comprises a door detachable from a box-shaped rack, a mounting hardware connecting the door to the rack and pivoting on one side so as to make the door openable and closable, and at least one excess length organizing holder mentioned above whose baseboard is attached on a surface of the door when the door is attached to the mounting hardware.

Claims

1. An excess length organizing holder comprising:

a baseboard which has a rotation axis vertical to a fixed plane; and

a spool which has a flange whose edge is provided with two incisions and a winding portion, and rotates around the rotation axis in a state where a cable is folded by way of the winding portion and the two incisions, thereby winding the cable twofold around the winding portion.

2. The excess length organizing holder as claimed in claim 1, wherein a guide channel is provided on a surface of the flange so as to connect the two incisions.

3. The excess length organizing holder as claimed in claim 2, wherein the guide channel is curved so that in combination with the winding portion, equal to or more than a predetermined bend radius is maintained for the cable as folded.

4. The excess length organizing holder as claimed in claim 1, further comprising anti-reverse rotation means which stop a rotation in a reverse direction to a winding direction of the spool.

5. The excess length organizing holder as claimed in claim 4, wherein the anti-reverse rotation means comprise a salient rotation stopper provided on one of contacting surfaces between the spool and the baseboard and a rotation stopper catching slot provided on the other surface.

6. The excess length organizing holder as claimed in claim 1, wherein the baseboard is provided with fixing means which fix the baseboard to a desired fixing position.

7. A multistage excess length organizing holder comprising:

a plurality of excess length organizing holders as claimed in claim 1,

one of the excess length organizing holders being made a primary holder, and the other excess length organizing holders being made extension holders, whereby at least one of the extension holders is connected to the primary holder with connecting means so that the rotation axes of the extension holders are fixed on a same axis as the rotation axis of the primary holder.

8. The multistage excess length organizing holder as claimed in claim 7, wherein the connecting means comprise a combination of a ridged axis provided on each of the baseboards and a slotted bearing that fits the ridged axis.

9. The multistage excess length organizing holder as claimed in claim 7, wherein the baseboard of the primary holder has fixing means which fix the baseboard to a desired fixing position.

10. An excess length organizing structure comprising:

a door detachable from a box-shaped rack;

a mounting hardware which connects the door to the rack and pivots on one side so as to make the door openable and closable; and

at least one excess length organizing holder as claimed in claim 1 whose baseboard is attached on a surface of the door when the door is attached to the mounting hardware.

11. The excess length organizing structure as claimed in claim 10, wherein the door has a rail and a projection, and the mounting hardware has a rail groove fitting the rail and a slantly formed depressed groove enabling the projection to slide, so that the door is attached to the rack by sliding down the projection slantly along the depressed groove.
