CORD HOLDER Filed April 28. 1965 INVENTOR. SAMUEL 5/410 ATTORNEY United States Patent 3,312,434 CORD HOLDER Samuel Simon, Poughkeepsie, N.Y., assignor to Prosit Service Corporation, Wappingers Falls, N.Y. Filed Apr. 28, 1965, Ser. No. 451,403 1 Claim. (Cl. 248-62) The present invention relates to a cord holder, and more particularly to a balanced cord holder for the water, power and light cords of a cystoscope.
In the use of the cystoscope for examination and surgery, a problem has always been in the supporting of the water, power and light cords of the cystoscope. These cords must be supported so that they do not contact the patient and so as to permit movement of the cystoscope without any tension or pull on the cystoscope. Heretofore, the cystoscope cords were either held by a nurse or an attendant, or were supported by such makeshift arrangements as twisted rubber bands with safety pins or overhead steel cables with pulley arrangements. However, none of these support-ing means were satisfactory.
It is an object of the present invention to provide a novel cord holder.
It is another object of the present invention to provide a novel holder for the water, power and light cords of a cystoscope.
It is still another object of the present invention to provide a cystoscope cord holder which provides an overhead, balanced support for the cords and permits the cords to follow movement of the cystoscope without applying tension or pull on the cystoscope.
It is further object of the present invention to provide a cystoscope cord holder which is simple in construction, light in weight and easy to use.
Other objects will appear hereinafter.
For the purpose of illustrating the invention, there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIGURE 2 is a sectional view taken along line 22 of FIGURE 1.
FIGURE 3 is a sectional view taken along line 33 of FIGURE 1.
- FIGURE 4 is a sectional view taken along line 44 of FIGURE 1.
Referring initially to FIGURE 1, the cord holder of the present inventionally is generally designated as '10.
Cord holder comprises a vertically extending mounting tube 12 having a flat mounting plate 14 secured to its upper end. The mounting plate 14 has a plurality of holes 16 therethrough through which screws or bolts can extend to secure the mounting plate 14 and mounting tube 12 to the ceiling of a room. A headed set screw 18 is threaded through the wall of the mounting tube 12 adjacent the lower end of the tube (see FIGURE 3). The upper end of a vertically extending mounting rod 20 slidably extends into the mounting tube 12 and is secured therein by the set screw 18. As shown in FIG- URE 3, the bottom end of the mounting rod 20 is bent to form a pivot pin 22 which is perpendicular to the mounting rod. The free end of the pivot pin 22 is threaded.
A supporting rod 24 is pivotally mounted on the pivot pin 22. Supporting rod 24 has a plurality of spaced, diametrically extending holes 26 therethrough at the center portion of the rod. The pivot pin 22 extends through one of the holes 26 and a nut 28 is threaded on the pivot pin to secure the supporting rod on the pivot pin. A hanger sleeve 30 is slidably mounted on the supporting rod 24 at one side of the pivot pin 22. Hanger sleeve 30 has an eye 32 forward on its outer surface. A headed set screw 34 is threaded through the wall of the hanger sleeve 30 and engages the supporting rod 24 to secure the hanger sleeve at a desired position on the supporting rod. A counterbalance sleeve 36 is slid-ably mounted on the sup porting rod 24 at the other side of the pivot pin 22. A headed set screw 38 is threaded through the wall of the counterbalance sleeve 36 and engages the supporting rod 24 to secure the counterbalance sleeve at a desired position on the supporting rod. Separate headed pins 40 extend diametrically through the supporting rod at the ends thereof to prevent the hanger sleeve 30 and counterbalance sleeve 36 from sliding off of the supporting rod.
A hanger plate 42 is supported from the hanger sleeve 30 by a hanger rod 44. Hanger rod 44 has a loop 45 at its top and which extends through the eye 32 of the hanger sleeve 30, and a loop 48 at it bottom end which extends through a hole 50 in the center of the hanger plate 42. Three clips 52 are secured in spaced relation to the hanger plate 42 by screws 54. Each of the clips 52 comprises a pair of arms 52a and 52b pivotally connected together. The arms 52a and 52b have mating cord re- 'ceiving notches 53a and 53b respectively in the lower ends of their facing surfaces. A spring 55 is compressed between the facing surfaces of the arms 52a and 52b adjacent their upper ends and normally holds the bottom ends of the arms together. The screws 54 extend through the top ends of the arms 52a of the clips 52 with the cord receiving notches 53a and 53b being below the hanger plate 42.
To use the cord holder 10 of the present invention, the cords 56, 58 and 60 of the cystoscope are each placed through the cord receiving notches 53a and 53b of a separate one of the clips 52 as shown in FIGURE 1. The mounting rod 20 can be moved vertically within the mounting tube 12 to adjust the height of the support for the cords and locked at the desired position by the set screw 18. The hanger sleeve 30 can be moved along the supporting rod 24 to properly position the support for the cords with respect to the patient, and the hanger sleeve is locked in the desired position by the set screw 34. The pivot pin 22 is inserted through the proper hole 26 in the supporting rod 24 to provide the desired movement of the cords 56, 58 and 60. If a large amount of movement of the cords is desired, the pivot pin 22 should be inserted in the hole 26 furthermos-t from the hanger sleeve 30, whereas if only a limited amount of movement is required, the pivot pin can be inserted through the hole 26 closest to the hanger sleeve 30. The counterbalance sleeve 36 is positioned along the supporting rod 24 so -as to balance the weight of the cords 56, 58 and 60, and is locked in position by the set screw 38.
In the use of the cord holder 10, the cords 56, 58 and 60 are firmly supported out of contact with the patient. However, upon movement of the cystoscope, the supporting rod 24 will pivot to permit the cords 56, 58 and 60 to follow the movement of the cystoscope. Since the weight of the cords is balanced by the counterbalance sleeve 36, only a slight force is necessary to move the cords, yet the cords will remain in any set position without any pull or tension on the cystoscope. In addition, the cord holder 10 of the present invention is of simple construction so that it does not take up much room and can be easily assembled and used.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claim, rather than to the foregoing specification as indicating the scope of the invention.
