Definitions

  • This invention relates to crutches.
  • a principal object of the present invention is to provide a crutch assembly which better distributes the weight of the user, relieving the pressure points conventionally produced under the arms and at the wrists, hands and elbows, and thus requiring less energy.
  • Other objects include providing such crutch assemblies that can be easily adjusted in length according to the particular user or, during use, to the particular situation.
  • the invention features a cross-member adapted to be strapped to a user, and a pair of crutch members attached to the cross-member in such a way as to be free to pivot through a solid angle with respect to the cross-member.
  • the crutch members of the assembly are free to pivot through solid angles of about ⁇ /2 steradians, i.e., 45° to the front and rear, and 30° in towards and 60° out away from the user.
  • Each crutch member may either be a short assembly adapted for connection to a conventional crutch, or a full length crutch.
  • a full length crutch member comprises a pair of telescoping supports to be moved relative to each other to adjust the crutch member in length, and at the proper length to be locked in position.
  • Fig. 1 is a perspective view of a first preferred embodiment
  • Fig. 2 is a perspective view of portion of the first embodiment
  • Fig. 3 is a sectional plan view taken at 3-3 of Fig.
  • Fig. 4 is a sectional view taken at 4-4 of Fig. 3;
  • Figs. 5 A-C show the embodiment of Fig. 1 attached to a user
  • Fig. 6 is a perspective view of a second preferred embodiment
  • Fig. 7 is a sectional view taken at 7-7 of Fig. 6;
  • Fig. 8 is a perspective exploded view of portion of the embodiment of Fig. 6; and.
  • Figs. 9 and 10 are perspective, partially exploded views of a third embodiment.
  • Figs. 1-5 disclose a crutch assembly, generally designated 10, comprising a cross bar 12 having crutches 14 attached to the opposite ends thereof by ball and socket joints 16.
  • a padded sleeve 18 covers bar 12 along most of its length.
  • the opposite ends of an adjustable strap 20 are attached by split "D" rings 22 to bar 12 adjacent its ends. As shown, each "D" ring 22 projects into diametrically-opposed drilled holes 24 in bar, a series of such holes being provided adjacent each end of bar 12 so the distance between the ends of straps 20 may be varied to fit a particular user.
  • Each ball and socket joint 16 includes a ball 25 attached to the upper end of a crutch 14 and received within a socket 26 at the adjacent end of bar 12, and permits the crutch 14 to pivot relative to bar 12 through a solid angle (i.e., both back and forth and to the side).
  • the solid angle is about ⁇ /2 steradians (i.e., momement is permitted through an arc of about 45° both back and forth, and 30° in and 60° out away from the user); and preferably the movement permitted will never be less than about 30° back and forth and out from the side.
  • Each crutch 14 includes a pair of telescoping cylindrical tubes 28, 30.
  • a broad-based flexible rubber tip 32 fits on the bottom of the lower, smaller diameter tube 28; and ball 25 is fixed to the top of the larger diameter tube 30.
  • upper tube 30 is bent about 25° in an area, designated 31, about one-third of the way down from its upper end.
  • Lower tube 28 is straight.
  • Handle 34 projects generally perpendicularly from upper tube 30, about one foot below bend 31 and a short distance above the bottom 33 of tube 30. The upper portion of tube 28 fits within tube 30, forming a slip-fit so that the two tubes may be moved axially relative to each other.
  • a helical spring 36 within tube 30 is interposed between a stop 38 carried by through bolt 39 and the upper end 40 of tube 28.
  • a stepped cylindrical plug 42 projects axially downwardly from stop 38 a short distance into the top of spring 36; and a similar plug 43 is fitted into tube upper end 40, both engaging the lower axial end of the spring 38 and projecting a short distance into the bottom of the spring.
  • the exterior upper portion of tube 28, front end downwardly a distance of slightly over a foot, defines a number of circular axially spaced ribs 44, the outer periphery of which form slip-fits with the inner surface of tube 30.
  • Handle assembly 34 comprises a "T", including sleeve 46 surrounding and attached to tube 30 and a cylindrical grip 48 projecting generally perpendicular to the axes of sleeve 46 and tube 30.
  • a generally annular recess 50 aligned with grip 48 within and midway the length of sleeve 46, overlies a cut-away portion 49 of the cylindrical wall of tube 30.
  • an adjusting stop 52 is mounted in recess 50 surrounding tube 28.
  • the inner bore 54 of stop 52 has a width (perpendicular to the axis of grip 34) slightly greater than the outside diameter of tube 28, a length (parallel to the axis of grip 34) greater than the sum of the diameter of tube 30 and the height (peak to valley) of tube ribs 44.
  • a plurality of axially-spaced grooves 56 arranged to receive and engage ribs 44 are provided on the side of stop 52 oppositegrip 48.
  • a push rod 58 is attached to the side of stop 52 opposite grooves 56, and extends axially through the length of grip 48, providing a projecting push button 60.
  • Compression spring 62 surrounds rod 58, within grip 48, with the opposite ends of the spring engaging the end 66 of grip central bore 64 nearest stop 52 and an annular ring 68 on rod 58.
  • spring 62 tends to draw grooves 56 of stop 52 onto engagement with tube ribs 44, thus locking tube 28 in place axially relative to tube 30.
  • push button 60 is depressed (as shown in Fig. 3), moving the grooves 56 of stop 52 out of engagement with ribs 44 of tube 28, so that tube 28 is free to slide axially, relative to and within tube 30.
  • a wearer 100 places cross bar 12 behind his back and straps himself to it.
  • cross bar 12 is positioned just below the user's shoulder blades, and strap 22 is buckled under his arms and across his chest, all as shown in Figs. 5 A-C.
  • Crutches 14 may be positioned, as desired, when walking or standing; and their length may be adjusted at any time, even in use as, for example, when descending stairs 102 as shown in Fig. 5B.
  • FIG. 6-8 illustrates a second embodiment, generally designated 10', for use with conventional crutches.
  • clamp assemblies 104, 106 are connected by ball and socket joints 16' to the opposite ends of padded cross bar 12'.
  • Each clamp assembly 104, 106 securely engages the adjacent uprights 108 of a conventional crutch 110, just below the padded rest 112 of the top of the crutch 110.
  • Each of clamp assemblies 104, 106 includes a base member 114 one end 116 of which is attached to the post 118 carrying ball 25' and the other end 120 of which engages a slot 122 in clamp cover member 124.
  • Recesses 125 in base member 114 and cover member 124 are shaped to receive crutch uprights 108, and bolts 126 attach the base and cover members to each other securely engaging the crutch uprights therebetween.
  • the user straps the entire crutch assembly 10' into place, with cross bar 12* held in place behind his or her back and chest encircling strap 20' passing under arm.
  • Figs. 9 and 10 also illustrate the construction of the ball and socket joint used in all the herein described embodiments, and of a modified connector 210, for use in any of the described embodiments, for connecting strap 20;; to bar 12 ' '.
  • socket 26 '' is formed by a cylindrical bore 212 at an end of bar 12 ' ' , the top and bottom of which are closed by identical circular plates 214, 216, bolted in place.
  • Ball 25'' fits closely within bore 212, with its post 216 extending through a central hole 220 in plate 16, and engages ball recesses 222 (each in the form of a spherical zone) on the inner surfaces of plates 214, 216 surrounding holes 220.
  • One end of post 208 is welded in place in a radial bore in ball 25' '; its other end is pinned in a bearing sleeve 224 at one end of cap 200.
