Abstract
Description
- The present invention relates to a lifting sytem and particularly to a chair lift for use in hospitals and residential homes to lift an immobile patient into and out of a bath.
- In such a system, it is of course important that the chair in which the patient sits is held firmly and cannot rotate about any horizontal axis so as to unbalance the patient.
- Accordingly, the invention provides a lifting system comprising a lift and support for a load, a member on one of the lift and support having a vertically arranged bore to closely receive a pin of the other of the lift and support and having locking means to lock the pin in the bore.
- Preferably the support comprises a seat mounted on a rigid frame. The frame may include means for mounting the seat on a mobile frame for manoeuvering the patient before and after the lifting operation.
- Preferably the member is on the support and ideally a part of the frame.
- The locking means may comprise a selectively operable element horizontally slidably disposed in the member and a groove formed on the pin adapted to be engaged by said element when the pin is in the bore. Preferably said element is C-shaped and said groove is annular, the arms of said C-shaped element being arranged to engage the groove on either side of the pin when it is positioned in the bore.
- Thus in operation a patient seated on the seat carried by the mobile frame is positioned underneath the lift. The lift is lowered such that the pin. engages the bore of the member and the locking means can be engaged to lock the pin in the bore.
- Rotation of the member relative to a horizontal axis is prevented by the arrangement. Thus the lift can be operated and the patient will be raised on the seat without fear of being tipped out of the seat.
- Where the pin. is mounted on the lift it is preferably arranged rotatable about a vertical axis. Preferably the pin is mounted at the end of a horizontally arranged arm, itself rotatably mounted about a vertical axis on the lift.
- Thus once the patient has been lifted by the lift, the arm can be rotated to position the patient above a bath and the pin and thus the member,frame and seat connected thereto can be rotated to position the patient squarely over the bath, whereupon the lift can be lowered to lower the patient into the bath.
- The invention is further described hereinafter with reference to the accompanying drawings in which:
- Fig. 1 is a perspective view of a lifting system in accordance with the invention;
- Fig. 2 is a vertical section through a post and member of a lifting system according to the invention taken along the lines II- II of Fig 3; and
- Fig. 3 is a section along the lines III-III in Fig. 2.
- In Fig. 1 a
lift 10 comprises abase 12 securely fixed to the ground. Thelift 10 has acentral post 14 on which is telescopically mounted asleeve 16. Thebase 12 includes means to raise and lower thesleeve 16 with respect to thepost 14 to effect a lifting operation. Said means is well known in the art and requires no further description here. On the top end of thesleeve 16 is rotatably mounted anarm 18 which at a radial distance from thesleeve 16 rotatably mounts apin 20. Both thepin 20 andarm 18 are rotatable about vertical axes only. - A
support 30 comprises aseat 31 mounted on atubular frame 32 provided with amember 34 positioned above and behind theseat 31. Thesupport 30 is a rigid arrangement. - A
mobile frame 40 haswheels 42 and twoangled sections 44,46 adapted to receiveparts frame 32 of thesupport 30. Themember 34 has abore 38 adapted to receive thepin 20 of thelift 10. Theframe 32 is so arranged that theparts angled sections 44,46 of themobile frame 40 such that, when theframe 40 is on a horizontal floor thebore 38 is arranged with its axis vertical. Although it is not shown in the drawings, it is quite feasible that one or both of theangled sections 44,46 may be rendered adjustable such that where the floor on which thelift 10 is mounted is not horizontal, nevertheless thebore 38 can be arranged substantially vertical when theframe 40 is positioned appropriately. - With the
support 30 on themobile frame 40 theframe 40 is positioned underneath thearm 18 of thelift 10 such that thebore 38 is substantially immediately below thepin 20. Thelift 10 is then lowered to engage thepin 20 into thebore 38. - Turning to Figs. 2 and 3, the
pin 20 is provided with a tapered or chamferedend 22 and likewise thebore 38 in themember 34 is provided with a chamfered opening 39. Thus even if the floor should be non-horizontal or not entirely flat, the chamfers on thepin 20 andmember 34 will allow thepin 20 to be channeled into thebore 38 working it into a vertical position. - In the
member 34 there is mounted a C-shaped element 51 which is slidably disposed in a horizontally alignedgroove 53 formed in themember 34. Thegroove 53 is arranged transversely of thebore 38 and theelement 51 is urged bysprings 55 to a position overlapping thebore 38. Thesprings 55 operate against an end plate 57 connected to themember 34 by, for instance,screws 59. Alever 60 is pivoted in themember 34 about apin 62 channeled in themember 34. One end of thelever 60 is provided with ahandle 64 operable by a user of the lift and the other end is provided with apin 66 engaged in aslot 68 in theelement 51. - Thus when the
pin 20 is to be positioned in thebore 38, the operator first pivots thehandle 64 in the direction of the arrow A in Fig. 2 to withdraw theelement 51 from the region of thebore 38. Thepin 20 is then lowered into thebore 38 until anannular groove 17 formed thereon aligns with thearms 54 of theelement 51. Thehandle 64 will have previously been released once the nose of thepin 20 has been worked sufficiently far into thebore 38 to prevent thearms 54 hindering the further passage of thepin 20. Thus once thepin 20 reaches the position shown in Fig. 2 thesprings 55 will shoot theelement 51 into the position shown where thearms 54 lock around thegroove 17. The extent of the engagement between the pin. 20 and bore 38 prevents anything other than very slight movement therebetween about a horizontal axis, thus when thelift 10 is operated to raise thesleeve 16 and hence thearm 18 andpin 20 there is no possibility of theseat 31 tipping forward, despite the leverage of the load tending in this direction. - In this manner, a patient on the
seat 31 can safely and securely be raised and lowered into a bath.
