Definitions

  • the present invention relates to a carriage and/or lifting device and a method of assembly and disassembly of such a device for use in carrying articles and objects such as but not limited to human bodies. More particularly, the invention relates to stretchers and/or litters of the general type having a flexible load support cradle sheet connected to gripping handles whereby the cradle sheet and handles may be readily assembled and disassembled.
  • carriage device of the present invention will primarily be described with reference to its application in carriage of sick, dead or injured persons this is not to be construed as a limiting application of the invention as the article to be carried is largely inconsequential to the utility of the device.
  • stretchers used in the first aid and ambulance field for use in the carriage of injured, sick or dead bodies.
  • These generally comprise a cradle sheet comprising a woven fabric or like soft, pliable material such as plastic or other synthetic which is attached to carry beams which generally run longitudinally along the periphery of the cradle material.
  • the beams of the prior art devices generally terminate at their ends in carry handles which enable an operator to grip the stretcher one at each end.
  • these stretchers have proven to be useful, they do have the significant disadvantage that they require a body to be lifted rather than rolled onto the stretcher. This constitutes both a difficulty to the assistants and a danger to a patient particularly if an injury has been sustained which makes movement of the patient unwise.
  • the subject prior art comprises a woven fabric cradle sheet divisible into two portions and comprising joining means for attaching said portions.
  • the sheet material also has loops which are adapted to receive carry handles therethrough.
  • this stretcher offers the advantage that it can be readily detached from the handles by sliding the handles through the loops and divided into two portions by release of the said joining means when the fabric cradle is to be pulled from under the patient, the handle connection arrangements are unsafe in that they are predisposed towards sliding out of the loops and the means for disconnection of the two portions is not entirely suitable as often the joining strap must be pulled when under the dead weight of a patient or other article on the stretcher. Furthermore, the fabric used in these stretchers is not intended for disposal in the event of soiling with blood or other matter. When the prior art sheets are to be cleaned, difficulties arise due to the ingress of soiling or infection matter between weaves and stitches.
  • the present invention therefore, seeks to ameliorate the disadvantages of the prior art stretchers by providing a stretcher having versatility in handling and assembly, optional disposability of the cradle sheet, security in relation to handle attachment and the ability to adjust the handles so as to optionally stiffen the support along the end edges and longitudinal edges of the sheet where articulation of the stretcher at the mid length region is not required.
  • the present invention combines a disposable sheet with a highly strong and effective releasable facility for engagement between the sheet and handle mechanisms without compromise to the overall structural integrity which existed in the prior art devices.
  • the present invention comprises; a carriage device of the type and class known as a stretcher or litter and having a cradle sheet supported by at least two carry handles characterised in that the device comprises; a continuous or segmented cradle sheet material having means connected thereto or integral therewith to releasably engage at least one outstanding retaining buckle on said carry handles.
  • said releasable engagement between said sheet and handles effected by interleaving of said means around at least one loop and return buckle attached to each of said handles.
  • said means on said sheet comprise tabs which outstand from the side edges of the sheet and which are configured so as to releasably engage said buckles.
  • the said buckles are optionally adapted to be movable along or around said handles or fixed in one position.
  • the present invention comprises: a) laying an opened out cradle sheet prostrate on the ground, b) laying first and second handles on the ground adjacent opposing edges of said sheet, c) feeding a tab on said sheet through a first opening at least partially formed by or in said buckle which is on said first handle, d) feeding the end of the tab back through a second opening formed by or in said buckle, e) repeating the process for additional buckles, f) repeating the process for said second handle.
  • the present invention comprises a method of assembly of a carriage device comprising the steps of a) laying an opened out cradle sheet prostrate on the ground, b) laying first and second handles on the ground adjacent the longitudinal edge of said sheet so that at least one buckle on said handles is faced away from said sheet, c) feeding a tab on said sheet over said first handle thence through a first opening, d) feeding the end of the tab back through a second opening so that the end of said tab points in the direction of the said sheet, e) rotating the handle in a direction away from the sheet so as to effect gripping engagement between the tab of said sheet and said handle, f) repeating the process for each buckle and for said second handle.
  • Figure 1 shows an assembled stretcher or litter according to the preferred embodiment of the present invention.
  • Figure 2 shows a developed profile view of the cradle sheet used in the stretcher of figure 1.
  • Figures show the steps in the method of attachment 3a, b & c: sheet of the cradle sheet of figure 2 to the handles of the stretcher in figure 1.
  • Figure 4 shows an alternative handle arrangement to that shown in figure 1.
  • Figure 5 shows the handles of figure 4 with a cradle sheet attached.
  • Figure 6 shows the device of figure 5 with handles on either side of the cradle sheet mated,
  • Figure 7 shows an exploded view of the invention according to an alternative embodiment having detachable end handles disposed at either end of the device which are adapted to engage the ends of the carry handles,
  • Figure 8 shows the device of figure 7 with the end carry handle attached.
  • FFiigguurree 99 shows a smaller version of the embodiment of figure 7 without the junctions at the midpoint of the handles.
  • Figure 10, 11 and 12 shows the end handles used in the device of figure 9 joined together following the elimination of the carry handles according to varied embodiments.
  • Figure 13 shows a partially exploded view of the embodiment of figure 8 but this time with segmented cradle sheets.
  • Figure 1 shows the carriage device 1 of the present invention according to a preferred embodiment.
  • the device comprises generally carry handles 2, 3, 4, 5 each having at least one fixed or movable buckle 6 which enables detachable support of a cradle sheet 7 via tabs 8 which are attached to or integral with the sheet 7.
  • Figure 2 shows a plan view of one configuration of the cradle sheet 7 with a series of outstanding tabs 8.
  • Figures 3a, b and c diagramatically detail the steps in interleaving the tabs 8 with typical buckle 6 located on handle 3 for illustration.
  • the device 1 is assembled according to the following steps. Sheet 7 is laid prostrate with tabs 8 pointing outwardly as shown in figure 2. Next, the handle 3 is laid substantially parallel to the longitudinal axis of the cradle sheet 7 with the buckle 6 turned away from the preventing tab. The tab 8 is then fed through gap 9, under bars 10 and 11 which form buckle 6, thence back through gap 12 between the bars. Arrow 13 defines the path of the tab 8 through gap 12 of bars 10 and 11.
  • the handle 3 is then rotated in the direction of arrow 14 so as to jamb and restrain the tab from slipping out of the buckle 6.
  • the resultant tension of the tab when the sheet is under load tends to increase the binding effect about bars 10 and 11.
  • the binding effect is at its strongest when the cradle sheet is under maximum load.
  • the cradle sheet 7 is made of polyethylene or polypropylene which is intended to be disposable however a longer life material such as a woven fabric could be substituted.
  • This device is particularly suitable for carrying injured, sick or dead people, especially where limited movement of such a person is desirable prior to carriage.
  • the device is also suitable where limited patient movement or manual lifting of a patient onto a stretcher is required is necessitated. In this case the patient may be rolled onto the cradle sheet first one way thence the opposite way before the handles are connected.
  • the embodiment of figure 1 is also suitable where some articulation of the carriage device is required.
  • Handle 3 is adapted with a telescopically operable member adapted to connect with end 16 of handle 2 to effect engagement between the handles. In like fashion, engagement between handles 4 and 5 is effected to form a single handle 20 running almost the full length of the carry sheet. This option is available where a more stiffened carriage device is required.
  • a spring loaded locking device holds the male joining member in position to effect positive engagement between the initially separate handles.
  • figure 1 shows two buckles per handle, it will be appreciated that a series of buckles could be used according to requirements.
  • Figure 4 shows an alternative configuration of buckles, on carry handles 2, 3, 4 and 5 whereby there are three aligned buckles.
  • the two handles 2 and 3 or 4 and 5 may also be attached together via two adjacent buckles by means of a flexible ring 17 or analogous linkage.
  • FIG. 5 shows the embodiment of figure 4 with a cradle sheet 18 attached.
  • Figure 6 shows the embodiment of figure 5 but this time with handles 2 and 3, 4 and 5 linked together by means of male female mating of male profile part 15 and end 16. The figure shows the handles mated together to form full length rigid handles 19 and 20.
  • male profile part 15 and end 16 can be interchanged without affecting the resultant connection between the handles 2 and 3 or 4 and 5.
  • the carrying device of figure 6 is shown in figures 7 and 8 with the addition of end support handles 21 and 22.
  • Figure 7 shows an exploded view of the device and figure 8' shows the handles 21 and 22 in situ.
  • the end handle 21 is essentially a mirror image of handle 22 and comprises a substantially U shaped portion which defines first and second legs 23 and 24 respectively and a bight whose base is bounded formed by member 25.
  • Each leg has a telescopic male member 26 shown extended from member 24 which is adapted to engage a corresponding female recess 27 in the handles 19 and 20.
  • the end handles 21 and 22 facilitate end carriage and stiffen the device peripherally for circumstances where rigid support of all edges of the sheet 7 is required.
  • Member 25 is preferably adapted with a buckle 29 to receive an end tab 30 on sheet 8 as shown in figure 8.
  • Figure 9 shows a further embodiment of the invention with the longitudinal handles abbreviated so that handles 2 and 4 remain unlike previously described embodiments. Connections of the sheet 7 to the handles are effected in a similar manner to that previously described for the other embodiments. End handles 21 and 22 are shown engaged with handles 2 and 4. This configuration of the invention is appropriate for small persons such as babies and children or small articles.
  • Figures 10, 11 and 12 show another embodiment of the invention whereby handles 21 and 22 are interengaged to form a miniature carriage device. In this embodiment a miniature cradle sheet 32 (see figure 12) is used. Junction between handles 21 and 22 is effected in a similar manner to that previously described with reference to figure 7 and 8.
  • Figure 13 shows an exploded view of one further embodiment of the invention where a segmented cradle sheet has been utilised.
  • the sheet is made from like but discrete intermediate segments 33 and end segments 34.
  • End segments 34 differ from segments 33 in that they have an additional end tab 35 which engages with buckles 29.
