Definitions

  • Wheelchair attachments coupled to wheelchair frames are used to support trays, recepticles and other equipment within reach of an individual confined to the wheelchair.
  • the attachments In order to maximize the advantages of these attachments it is necessary that they be easily adjustable to various verticle, horizontal, angular and combined positions relative to the individual. That is to say, the attachments should be substantially universally adjustable.
  • This invention contemplates a universally adjustable wheelchair attachment of the type which is coupled to the wheelchair frame for supporting equipment or the like for use by an individual confined to the wheelchair.
  • the attachment has three friction joints. A first and second of these friction joints are adjusted by a wrench and a third is adjusted by a knob.
  • a pair of columns coupled by the first joint are adjusted longitudinally and rotationally through an arrangement of collars and collar arms. One of the columns is coupled by the second joint to the wheelchair through a rotationally adjustable block. The other of the columns is coupled through the third joint to rotationally adjustable equipment support member.
  • a wheelchair member is designated by the numeral 2.
  • Wheelchair member 2 may be a horizontal or vertical portion of a wheelchair such as a wheelchair armrest made of metal tubular or bar stock. The wheelchair attachment of the invention is secured to member 2 as will next be explained.
  • An attachment block 4 includes a recess 6 which receives wheelchair member 2.
  • a strap 8 fits over wheelchair member 2 and is secured to block 4 by screws or the like 10, whereby block 4 is securely fastened to the wheelchair member in a rotational position relative thereto.
  • Block 4 has a hole 12 at one end thereof for receiving a bar 14.
  • Bar 14 is secured in block 4 by means of a set screw (not shown) tightened by a block arm 16. With the arrangement shown, bar 14 can be rotationally displaced about the longitudinal axis of bar 14 in opposite directions as shown by arrows (a) and (b) so as to orient the wheelchair attachment relative to wheelchair member 2, as will now be understood.
  • a column 17 includes a tube 18 having a yoke 20 at one end thereof, as best shown in Figure 2.
  • Bar 14 is received in yoke 20 and is separated on either side thereof by washers 22 which may be spring-type washers for purposes to be hereinafter explained.
  • a bolt 24 enters one side of yoke 20, extends through washers 22 and bar 14 and extends through the other side of the yoke where it is secured thereto by a washer 25 and a nut 26 which may be tightened and loosened by a conventional open end wrench.
  • column 17 may be angularly displaced away from and toward bar 14 as indicated by arrows (c) and (d) in Figure 1.
  • Tube 18 of column 17 receives in telescopic fashion a bar 28.
  • Bar 28 is logitudinally displaceable within tube 18 as shown by arrows (e) and (f) in Figure 1.
  • Bar 28 is secured in a desired longitudinal position within tube 18 by a collar 30.
  • Colalr 30 may be a conventional split collar which is tightened against tube 18 to squeeze the tube against the bar and to thereby hold bar 28 in the desired position by a collar arm 32 which tightens a set screw (not shown).
  • bar 28 can be rotationally displaced about its longitudinal axis as shown by arrows (g) and (h) in Figure 1 and secured in a desired rotational position by tightening collar 30.
  • a column 33 includes tube 34 having a yoke 36 at one end thereof as best shown in Figure 3.
  • Bar 28 is received in yoke 36 and is separated on either side therof by washers 38 which ray likewise be spring-type washers.
  • a bolt 40 enters one side of yoke 36, extends through washers 38 and bar 28 and extends through the other side of the yoke where it is secured thereto by a washer 41 and a nut 42 which is loosened and tightened by a conventional open end wrench.
  • tube 34 may be angularly displaced away from or toward bar 28 as indicated by arrows (i) and (j) in Figure 1.
  • Tube 34 receives in telescopic fashion a bar 44.
  • Bar 44 is longitudinally adjustable within tube 34 as shown by arrows (k) and (1) in Figure 1.
  • Bar 44 is secured in a desired longitudinal position within tube 34 by a conventional split collar 46 which is tightened against tube 34 to squeeze the tube against the bar and to thereby hold bar 44 in the desired position by a collar arm 48 which tightens a set screw (not shown).
  • bar 44 can be rotationally displaced about its longitudinal axis as shown by arrows (m) and (n) in Figure 1 and secured in a desired rotational position by tightened collar 46.
  • yoke 50 The end of bar 44 is received by a yoke 50 and is separated on either side thereof by spring washers 52.
  • a bolt 54 enters one side of yoke 50, extends through washers 52 and bar 44 and extends through the other side of the yoke, with a knob 56 being secured to the extending end of the bolt.
  • yoke 50 may be displaced about the axis of bolt 54 through knob 56 as shown by arros (o) and (p) in Figure 1.
  • a supporting plate 60 is secured to yoke 50 by means of a screw 62 and a wing nut 64.
  • Supporting plate 60 may be used to support equipment used by the individual confined to the wheelchair.
  • the equipment may be adapted to be fastened to the plate through screw 62 and wing nut 64 as will now be understood.
  • the aforementioned joints include spring washers 22, 38 and 52 respectively, which separate the bars 14, 28 and 44 from the respective yokes 20, 36 and 50.
  • the spring washers provide a friction force to maintain a desired angular position, but yet do not provide a positive lock in said position whereby an extensive amount of force is required to displace the bar to another angular position as may be desired.
  • This feature of the invention is of importance since it results in less frequent tightening and loosening of nuts 42 and 46 and knob 56 for adjustment purposes as is desireable.
  • a substantially universally adjustable wheelchair attachment is provided, with the adjustment being accomplished more easily than as heretofore been the case.
  • an infinite number of vertical, horizontal, angular and combined positions of the attachment relative to the wheelchair are possible.
  • the arrangement thereby enhances the use of the attachment in that is is capable of supporting a variety of equipment in a variety of positions. Further, the arrangement enhances adjustment by those confined to the wheelchair without the necessity of assistance of others as is desireable.
