Definitions

  • the present invention relates to an elevator device comprising a support structure and at least one laterally fixed column fitted with a hoistable load carrier, which is mounted for pivotal movement about the column, and with a lifting unit and a power unit, said units preferably mounted on the support structure to allow displacement of the load carrier vertically along the column.
  • An elevator device of the kind defined above is often used to allow disabled persons to reach e.g. elevated entrances and to bypass stairways.
  • Elevator devices of this kind comprises a plurality of mutually movable parts arranged to provide safe and convenient transportation. For instance, they often include a load-carrying platform, which is arranged to be lifted vertically when affected by a power unit, such as a motor. Often, the load-carrying platform is arranged to slide or be displaced in a horizontal plane in order to reach the top of the stairway or the like following the lifting operation. Likewise, such movements often are effected by means of a separate power unit . In order to avoid that the platform obstructs the entrance, it is of- ten arranged to pivot about a vertical axis.
  • the platform While being hoisted from a basic position at ground level to an unloading position, the platform is suitably pivoted over a quarter of a full turn. This pivotal movement usually is effected by means of an additional separate power unit, which serves to effect this movement of the elevator device.
  • the elevator structures In order to enable all three displacement movements, the elevator structures often become heavy, since every motor adds weight to the structure, in addition to which each motor needs a strong frame to which it may be attached, which adds further weight to the elevator structure .
  • the main object of the present invention therefore is to suggest an elevator device, which is capable of effecting the above displacement movements by means of one common power unit. Another object of the invention thus made possible is a reduction of the weight of the elevator device in order among other things to simplify the mounting work involved in installing the elevator.
  • the invention thus concerns an elevator device comprising a support structure and at least one laterally fixed column equipped with a hoistable load carrier, which is mounted for pivotal movement about the column, and with a lifting unit and a power unit, said units preferably mounted on the support structure to allow displacement of the load carrier vertically along the col- umn, said device being characterised by the provision of a follower and a guide, said follower and guide being arranged to engage one another in a groove in a point of contact located between the load carrier and the support structure, either the guide or the follower arranged to be fixed relative to the pivotal plane of the load carrier, thus causing a relative motion between the load carrier and the column, whereby the load carrier is forced to pivot about the column while being displaced vertically.
  • the follower preferably is arranged to be raised and lowered and to pivot about the column.
  • the load carrier is associated with the follower. Consequently, in a convenient manner the guide may be placed in engagement with the previously mentioned groove in the follower, at a suitable level relative to the curvature of said groove, in order to thus provide an advantageous pattern of the pivotal movement of the load carrier while the latter is being lifted from a starting position to an unloading position.
  • the inventive elevator device is adapted to allow exchange of follower of different kinds to suit the lifting unit and the column in dependence on the requirements on the lifting range and the radius of the pivotal movement of the load carrier.
  • This arrangement gives an addi- tional advantage in the industrial manufacture of the inventive elevator device, since the same basic model may be used to suit a large number of different entrances, as it is easy to exchange a follower the groove of which has an extension that is suitable for the intended entrance.
  • the guide comprises a pin for at least guiding engagement in the groove.
  • the pin is devised so as to make possible also at least some load transfer between the guide and the follower.
  • the invention allows the pivotal movement of the load carrier to be effected at a preferred level in a most simple manner because the pivotal movement is controlled by the position of the guide relative to the curved groove.
  • the guide could be e.g. a simple stud that may be attached at the desired level in a simple manner.
  • the elevator device is fitted with a load carrier comprising a platform-supporting runner, which runner together with the platform is arranged to slide relative to the support structure in a plane that essentially is perpendicular to the extension of the column.
  • a load carrier comprising a platform-supporting runner, which runner together with the platform is arranged to slide relative to the support structure in a plane that essentially is perpendicular to the extension of the column.
  • the platform may be arranged for sliding movements without additional power supply being required.
  • the runner may slide between two lateral extreme positions in response to at least two mutually tightened traction elements, which interconnect the runner and the lifting unit from opposite directions relative to the runner sliding-direction by suitable deflection of the traction elements, being acti- vated when the lifting unit causes vertical displacement of the load carrier to displace the platform forwards or backwards, respectively, between said lateral extreme positions, one of the traction elements pulling the sitions, one of the traction elements pulling the runner and consequently the platform in the desired direction.
  • the invention thus provides an elevator device which, by means of a single power unit, permits displace- ment of a platform perpendicularly to the vertical extension of the elevator device, as well as lifting a load carrier, lowering it alongside and pivoting it about a vertical axis.
  • the load carrier of the elevator device comprises a platform fitted with side members at the platform edges, said side members preferably being hinged.
  • This arrangement allows convenient rolling-on and rolling-off of a wheelchair or the like. Because the side members may be folded upwards, there is no risk that objects or persons may slide off the elevator platform supporting them.
  • the inventive elevator device should not either be regarded as a restricting factor but rather as an important advantage in normal use of the device.
  • the inventive elevator device could very well be given extra power in the form of e.g. additional motors.
  • the guide may be arranged to be moved and be locked in position.
  • An additional object of the inventive elevator device is that it should be simple to mount and dismantle. Thanks to the considerable reduction in weight that is obtained as a result of the lesser number of power units compared with those used in prior-art structures, an ele- vator device has been provided wherein each one of the components included therein may also be made lighter. This is a considerable advantage, considering that elevator devices of this kind for various reasons often need to be moved. In this case it is a great advantage that mounting and dismantling may be performed by one person only, which is made possible in accordance with one preferred embodiment, wherein each component has a maximum weight of 25 kilos.

  • the lifting unit 3 is shown when affected by a retracting force from the power unit 2, which force pushes the sleeve 4 upwards along the column 10 and consequently also urges the follower 7 upwards.

  • This second extreme position of the elevator device 1 is shown in Fig Id. In this position, the lifting unit 3 assumes its maximum contracted position.
