Definitions

  • the present invention relates to improvements in metcarriagesand arrangements in extensible stretcher sleds or carriages, and particularly in relation to ambulance vehicles in which the stretcher sled can be moved between an inner and an outer end position/locked position, and in which the sled can be extended beyond the rear end of the vehicle when said sled is located in its outer end position, so as to facilitate removal and deposit of a stretcher from and onto the sled.
  • the object of the present invention is to provide a method and an arrangement which will solve the afore ⁇ said problems. This object is achieved by a method and an arrangement having the characterizing features set forth in the following claims.
  • the inventive method and arrangement provide many advantages.
  • the risk of the theft of pharmaceuticals from the ambulance is also reduced, as is also the ingress of exhaust gases.
  • the risk of injury to ambulance personnel is reduced, the spines of the personnel are subjected to less strain, and the stretcher-borne patient experiences a less adventuresome journey into the ambulance interior.
  • existing ambulance vehicles can be readily equpiped with the inventive arrangement.
  • Figure 1 is a schematic, transparent perspective view of an ambulance section with the stretcher sled in a retracted position
  • Figure 2 shows the sled in an extended position
  • Figure 3 is a perspective view of a section of the inventive arrangement in an inactive position
  • Figure 4 illustrates the arrangement of Fig. 3 in an active position.
  • Fig. 1 illustrates schematically and in perspective the rear part of an ambulance vehicle 1, having a rear door 2 and a so-called extensible stretcher sled 3, said sled being shown positioned within the confines of the vehicle-interior.
  • the stretcher sled 3 is intended to support a stretcher (not shown), and can be manouvered between an outer and an inner locked position, said sled being unlocked or released from said positions by manual activation of a lever 4 provided on the sled 3.
  • the sled is locked automatically in its respective end positions.
  • Fig. 1 shows the sled in its inwardly located end position
  • Fig. 2 shows the sled in its extended, outward end position.
  • the sled 3 rests on a support frame 5 provided, inter alia, with a number of rollers 6 which enable the sled 3 to move easily along the frame 5, between the outer and inner end-positions of said sled.
  • Guide means are also provided for guiding the sled 3 in relation to the frame 5, so as to prevent the sled from leaving the frame.
  • the aforedescribed sled 3 and frame 5 are known to the art and have long been used in ambulance vehicles to enable stretcher-borne patients to be placed in the ambulance and empty stretchers removed therefrom in a ready and easy fashion.
  • the stretcher together with the patient, is then placed on the ex ⁇ tended sled 3 and the sled is released from its outer, locked position, by corresponding manipulation of the lever 4, whereafter the stretcher-carrying sled is pushed to its inward, locked position (Fig. 1) and the rear door 2 of the ambulance is closed.
  • the ambulance is now ready to be driven away.
  • the stretcher sled 3 and the frame 5 are modified in the following manner.
  • the stretcher sled 3 is fitted with a gear rack 10 which extends in the direction of the longitudinal axis of the sled, as illustrated in Figs. 1 and 2.
  • a gear or pinion 11 connected to an electric motor 12 is mounted adjacent the stretcher frame 5 or on some suitable part of the ambulance.
  • the electric motor may suitably have the form of electric starting motor of the kind used, for instance, in automotive vehicles, said pinion wheel 11 being manouverable between an inactive position (Fig. 3) and an active position (Fig. 4).
  • the pinion wheel 11 meshes with the rack 10, in the active position of the drive.
  • Movement of the pinion wheel between its inactive and its active state is effected electromagnetically or by means of the elec ⁇ tric starting motor, which incorporates an axially dis- placeable rotor.
  • Current is delivered to the electric motor 12 from the battery of the ambulance vehicle and the electric motor 12 can be rotated over a desired period of time such as to bring the pinion wheel 11 into mesh with the rack 10.
  • the electrical circuit by means of which the electric motor 12 is operated includes an operating device in the form of a button 13 provided at a convenient height on the outside of the ambulance, in the vicinity of the rear door 2, see Figs. 1 and 2.
  • the electrical circuit also includes a microswitch (not shown) which is opera- tive to interrupt the current supply to the circuit, i.e. to stop further outward movement of the sled 3 when said sled has reached its outer end position.
  • the circuit includes a further microswitch (not shown) which is operative to interrupt the current supply to the circuit, i.e.
  • the circuit also includes a third microswitch (not shown) which func ⁇ tions to interrupt current supply to the electric motor 12 when the stretcher sled 3 is locked in its inner position.
  • the inventive arrangement operates in the following manner.
  • the ambulance personnel open the rear door 2 of the ambulance, release the stretcher sled 3 from its internal, locked position by manouvering the lever 4 and manually with ⁇ draw the sled 3 to its outer locked position/end posi ⁇ tion shown in Fig. 2.
  • This can be accomplished, because the pinion wheel 11 is then in its inactive state, shown in Fig. 3, and thus out of engagement with the rack 10.
  • the personnel then remove the stretcher from the sled 3 and push the sled manually to the vicinity of its inner, locked position, although not entirely to this position, whereafter the rear door 2 is closed, although not to its fully locked position.
  • the ambu ⁇ lance personnel then collect the patient.
  • the ambulance personnel take the following steps.
  • One of the stretch ⁇ er bearers presses the operating button 13, which can be done with his/her elbow, due to the convenient position of said button, without jeopardizing the balance of the stretcher bearers.
  • the stret ⁇ cher bearers/ambulance personnel must not stand within the swinging radius of the rear door 2 when pressing the button 13, since they, or the stretcher will then be struck by the door as it is automatically opened, or by the stretcher sled when it is automatically extended from its position within the ambulance. Pressing of the operating button will initiate the supply of current to the electric motor 12, which causes the pinion wheel 11 to move from its inactive position, shown in Fig.
  • the stretcher bearers/ambulance personnel can now comfortably place the stretcher-borne patient on the outwardly extending sled 3, in the aforedescribed manner, and then release the sled from its outer locked position, by appropriate manouvering of the lever 4, and then push the sled to its inner, locked position, shown in Fig. 3, and close the rear door 2.
  • the am ⁇ bulance can now be driven away.
  • the rear door 2 When the ambulance vehicle is equipped, for instance, with a central locking system, the rear door 2 need not be carefully moved to an almost closed and locked position when the ambulance personnel leave the am ⁇ bulance to collect a patient, and the rear door can instead be closed and locked and means can be provided which upon activating the operating button 13 automati ⁇ cally release the rear door so that the door can be opened by the sled 3.
  • inventive arrangement can be used in vehicles other than ambulance vehicles where automatic extension of a sled is desired.

Abstract

La présente invention se rapporte à un procédé et à un agencement pour chariots de brancard extensibles (3) de véhicules du type ambulance (1). Le chariot (3) peut être déplacé manuellement entre une position terminale intérieure (Fig. 1) et une position terminale extérieure (Fig. 2), dans laquelle le chariot (3) dépasse de l'arrière du véhicule (1). Avant la prise en charge d'un patient, le chariot (3) est placé dans une position proche de sa position intérieure bloquée et la porte arrière (12) du véhicule (1) est placée dans une position quasi-fermée ou dans une position fermée. Lorsque le patient est ramené sur le brancard, un dispositif de mise en marche (13) est actionné, ce qui produit l'ouverture automatique de la porte arrière (2) et la mise en mouvement automatique du chariot (3) dans sa position terminale extérieure/position bloquée. L'agencement comprend une crémaillère à engrenage (10) montée sur le chariot (3), un moteur électrique (12) et une roue à pignon (11) portée par le moteur, afin de permettre l'ouverture automatique de la porte-arrière (2) et la mise en mouvement automatique du chariot (3) dans sa position extérieure.
