Field of the Invention The present invention relates to the handling of lines and particularly to the manipulation of loops in lines so as to place such loops around objects. More specifically, this invention is directed to line carrying and placing apparatus. Accordingly, the general objects of the present invention are to provide novel and improved methods and apparatus of such character.

2. Description of the Prior Art There are numerous activities which require the placement of a line, for example a rope, around an object. Examples of such activities and the prior art devices which have been employed therein may be found in US Pat. No. 2,591,638 to Trafton, US. Pat. No.

2,81 1,217 to Palsson, US Pat. No. 2,944,518 to Hawks and US Pat. No. 3,072,429 to Stipan. As will be obvious from perusal of the above-mentioned Trafton, Hawks and Stipan patents, most prior art line handling devices have been characterized by a relatively high degree of mechanical complexity considering the nature of the task to be performed. Such mechanical complexity, of course, increases the cost and weight of the apparatus while simultaneously having a deleterious effect on reliability. At the other extreme of the prior art are devices such as that exemplified by the Palsson patent which, while rather simple in nature from a mechanical standpoint, required a great deal of attention and care during use in order to prevent disengagement of the line from the device at an undesired time.

While not limited thereto in its utility, the present invention has been found to be particularly well suited for use as an aid to the mooring of boats. There has been a long standing desire in the art to provide a line or rope holding device for use by the owners of small boats. To have such utility a rope holding device should be characterized by mechanical reliability, ease of use and moderate expense. With particular respect to facilitating use of the device, it is a requisite that the rope holder be capable of storing a loop in any position prior to the actual moment of use and that the rope holder device itself be of such nature that it will not take up undue space on board a boat when not in use.

SUMMARY OF THE INVENTION The present invention overcomes the above briefly discussed deficiencies and other disadvantages of the prior art by providing a novel and improved line carrying and placing apparatus. The apparatus of the present invention is characterized by ease of use, detachability from a handle for storage and comparatively low fabrication cost.

The foregoing characteristics result from and the abovestated objectives are accomplished by a line holding device comprising a pair of arcuate flexible arms. These flexible arms define arcs of the same radii and of less than 180 whereby a circle having an opening or gap between the oppositely disposed ends of the arms is transcribed. The arms are hollow in nature and are slotted along their entire length. The arms are supported in such a manner as to cause the slots to face toward the center of the circle transcribed thereby. Accordingly, a loop at the end of a line may be inserted within the arms via the slots therein and the loop will thus bridge the gap between the arms. The supporting BRIEF DESCRIPTION OF THE DRAWING The present invention may be better understood and its numerous objects and advantages will become apparent to those skilled in the art by reference to the accompanying drawing wherein like reference numerals refer to like elements in the several figures and in which:

FIG. 9 is a perspective view of the FIG. 1 embodi- I DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the drawing, and as may best be seen from joint consideration of FIGS. 1 and 9, the disclosed embodiment of the present invention comprises a pair of

flexible arms

10 and 12.

Arms

10 and 12 will typically be comprised of rubber or other suitable rubber-like plastic material. Thus, by way of example,

arms

10 and 12 may be formed from commercially available hoses which are cut to length and thereafter split as shown in FIG. 7. The slot in each of

arms

10 and 12 formed during the splitting operation will, of course, be smaller in width than the inner diameter of the hose material which defines the arms. The length of

arms

10 and 12 is selected so that, when installed on the support structure to be described below, each of

arms

10 and 12 defines an arc of less than Thus, with the apparatus assembled as shown in FIGS. 1 and 9, the

arms

10 and 12 transcribe a circle having a gap in its circumference between the oppositely disposed free ends of the flexible arms. As may be seen from FIG. 9, the split or slot in

arms

10 and 12 faces toward the center of the circle defined thereby.

The support structure for

arms

10 and 12 may best be seen from a joint consideration of FIGS. 1-3. A metallic band 14, which may be comprised of a strip of spring steel, is inserted into

arms

10 and 12 and fastened to each of the arms by a plurality of suitable appropriately spaced mechanical means as indicated at 16. Band 14 will be resilient and will be formed into an are having a radius commensurate with the radius of the circle defined by arms and 12. The length of the are transcribed by band 14 will be approximately 180 of the circumference of the circle of

arms

10 and 12. Band 14 supports

arms

10 and 12 internally thereof along a substantial portion of their length while simultaneously permitting movement of the free ends of

arms

10 and 12 away from one another.

Partial external support for

arms

10 and 12 is provided by

brace members

18 and 20. Brace

members

18 and 20 will typically also be comprised of metal and will be possessed of at least a limited degree of resiliency whereby

members

18 and 20 will provide support for

arms

10 and 12 but will not substantially impede movement of the free ends of

arms

10 and 12 in the plane of the circle defined thereby. Brace

members

18 and 20 are formed as shown so that the first ends thereof will assist in defining the closed" shape of the circle"; i.e., the gap between

members

10 and 12. The first ends of

brace members

18 and 20 are attached to

arms

10 and 12 while the second end of each of the brace members is affixed to a common member as will be described below. To secure the first ends of

brace members

18 and 20 to the line holder, suitable fastening means such as rivets 22 will pass through each of

members

18 and 20, the adjacent one of

arms

10 and 12 and the band of spring metal 14 as shown in FIG. 3.

The support structure for

arms

10 and 12 also comprises a bracket member 24 which is attached, by any suitable means, to band 14. Bracket member 24 will typically be comprised of plastic and will be in the form of a T-shaped reducing socket having a flat top bar extending transversely from a tubular leg. The top bar of member 24 is provided with apertures which receive fasteners, such as fasteners 26, which pass through strip 14. The tubular leg of member 24 will, as shown in phantom, typically have a first threaded portion 28 of reduced diameter and a lower unthreaded portion 30 of increased diameter. Accordingly, in the manner to be described below, when in use either a threaded detachable handle 32 or any conveniently available unthreaded pole-like member of appropriate diameter may be employed with the invention.

The second end of each of

brace members

18 and 20 is, as may best be seen from joint consideration of FIGS. 2 and 6, provided with a slot or cut-out whereby those members can function as hasp plates. A pair of arcuate

pressure plate members

34 and 36 are positioned inwardly toward handle 32 from the second ends of

brace members

18 and 20.

Members

34 and 36 may be comprised of metal and will be stamped to define hasp staple portions which extend outwardly through the slots in

brace members

18 and 20 as shown in FIG. 6. The band 38 of an adjustable spring clamp will pass between the exterior surfaces of

members

18 and 20 and the interior of the staple portion of

pressure plates

34 and 36, as also shown in FIG. 6, whereby the pressure plates and brace members are locked together. Manual adjustment of the spring clamp via its wing nut will permit the rope holding device to be securely affixed to the handle 32 after its insertion between the

pressure plates

34 and 36 and into the socket of member 24. It will, of course, be understood that there are numerous other possibilities with respect to the manner of joining the pressure plates, brace members and spring clamp. Thus, by way of example, the

pressure plates

34 and 36 may be made integral with the

brace members

18 and 20 and the loops for receiving the band 38 of the spring clamp may be integral with or attached to

members

18 and 24 such as, for example, by welding.

If deemed necessary or desirable a further split hoselike member 40 may be mounted on the band 38 of the spring clamp for providing additional support for a line as depicted in FIG. 9. The manner of mounting member 40 to band 38 may be as shown in FIG. 5 although obviously other possibilities are available.

Referring to FIGS. 7 and 8, the free ends of

flexible arms

10 and 12 may be formed as shown to enhance the utility of the apparatus. Thus, the free end of arm member 10 may be formed into a point as shown so that arm 10 may be readily passed beneath a line which will thereupon fall into the center of the circle" and may be lifted with the apparatus. Similarly, the end of arm 12 is formed into a V-shaped groove whereby a line may be supported in the groove and manipulated; the apparatus having to be turned clockwise or counterclockwise from the position shown in FIG. 9 in order to implement the added functions permitted by the shaped ends of

arms

10 and 12.

With reference now to FIG. 9, a typical use of the disclosed embodiment of the present invention is depicted. In FIG. 9 a hawser 42 having a loop at the end thereof has been inserted in the apparatus in such a manner that the loop is fitted within and supported by the slotted

flexible arms

10 and 12. Hawser 42 is also supported intermediate its length by split-member 40. Although various modes of operation are possible, it will be presumed that the rope holding device has been stored on board a boat with the hawser already installed thereon. When it is desired to moor the vessel a handle 32 is inserted between

pressure pads

34 and 36 and into socket member 24. Secure attachment of the handle to the remainder of the apparatus is achieved by tightening the spring clamp and, if appropriate, by turning the handle to engage the threaded endthereof with the internal threads in member 24. Employing the handle, the rope holder is extended outwardly and then brought down over the piling to which it is desired to moor the boat. The rope holder is thereupon withdrawn longitudinally with

arms

10 and 12 flexing outwardly as they pass about the piling. As the rope holder is withdrawn the hawser 42 will be pulled out of the slots in

arms

10 and 12 and the looped end thereof will remain about the piling. Should it later be desired to disengage the hawser from the piling the loop may be loosened and the hawser raised using the apparatus of the present invention and particularly by taking advantage of the shaped ends of

flexible arms

10 and 12.

While a preferred embodiment has been shown and described, various substitutions and modifications may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understoodthat the present invention has been described by way of illustration and not limitation.
