Definitions

  • the invention relates to a device capable of transferring a load over a trajectory connecting two positions situated at different levels and it includes a support member that can be anchored which is located in connection with the upper level and at least one rotating lifting arm pivoted at one end on said support member and equipped on the other end with means to effect its fastening to the load to be transferred.
  • the object of the present invention which attempts to resolve the above mentioned problems, and it consists of a device characterized in that the means for fastening are designed and positioned so as to rotate, by the sole effect of gravity acting on the load in relation to the arm while it completes the whole transfer trajectory so that the barycentric axis of the load itself is always essentially contained within the vertical plane that passes through the point or points of suspension, and in that it possesses means capable of reducing the effort necessary for operating the device, at least for one part of the above mentioned trajectory.
  • figure 1 represents the lateral view of a lifting arm designed according to the invention so as to reduce the effort in the final part of the transfer of the load;
  • FIG. 2 represents the prospective view of a preferred embodiment suited for the loading of a bicycle on the roof of an automobile;
  • figure 3 represents an alternative embodiment for the same device as in figure 2 ;
  • FIG. 4 represents the lateral view of another embodiment of the invention equipped with hooks that can be rotated for holding the -wheels of a bicycle or motorcycle.
  • FIG. 5 represents a further example of an embodiment of the invention suitable for loading several bicycles at the same time
  • FIG. 6 represents a detailed view of the device alone in a more enlarged prospective view according to a preferred embodiment
  • FIG. 7 represents the prospective view of a device according to the invention in which a spring is installed so as to reduce the effort in the final part of the loading trajectory;
  • - figure 8 represents the view in longitudinal cross-section of the hinging pivot of the lifting arm with two elastic springs applied to the torsion
  • - figure 9 represents the lateral view of a preferred embodiment of the device according to the invention with the load free to also rotate around a vertical axis
  • FIG. 10 represents a more close-up prospective view of the device in figure 9.
  • Figure 1 shows, with a diagrammatically represented load, one of the concepts which are the basis for the invention: load 4, connected so that it can rotate in relation to lifting arm 1 during the entire transfer trajectory 5 from lower level ⁇ to higher lever ⁇ , by the effect of gravity, is constantly maintained in a vertical position.
  • the manual effort to operate the device is furthermore necessary only in first segment 5A of the trajectory, inasmuch as in segment 5B, once the barycenter of load 4 has gone beyond the vertical that passes through the hinging pivot, it will be the weight of load 4 itself that will work together with the user in causing lifting arm 1 to rotate until it reaches its final position.
  • Lifting arm 1 is divided into two parallel bodies le and If, both of which can be extended telescopically, integral with one another and folded like an L, the end of the shorter side of which is hinged in 2 on support member 3 suitable in turn for being connected either directly to the roof of the automobile or to structure 15 of the known type (baggage rack, ski-racl) already attached to the roof itself.
  • the means for attaching lifting arm 1 to load 4 consist, for example, in the case of bicycles or motorcycles, of a member connected to the free end of arm 1 itself so that it can rotate in relation to it and equipped with members capable of engaging with the two stanchions forming a "V" (so that either men's or women's bicycles or motorcycles can be attached) of frame 4a of the vehicle that is to be loaded.
  • V a "V" (so that either men's or women's bicycles or motorcycles can be attached) of frame 4a of the vehicle that is to be loaded.
  • the above mentioned member capable of rotating is metal tube 6 that is telescopically extendable to one or both ends, on which connections 6a and 6b that are capable of connecting with the above mentioned "V" stanchions of a bicycle or another similar vehicle.
  • connections 6a and 6b that are capable of connecting with the above mentioned "V" stanchions of a bicycle or another similar vehicle.
  • connections 24 and metal tube 23 are designed in a different manner.
  • figure 4 represents an embodiment adapted for the loading and transporting of motorcycles or the like that have a similar weight: to the free end of lifting arm 1, or to an intermediate member that is integral with it, two hooks 7 and 8 with vertical development, the loops 7a, 7b of which (in the drawing only one is visible, since the two hooks are actually exactly overlapping) are capable of making possible the support and containment of one wheel.
  • hooks 7 and 8 themselves, means for fastening the wheel are then applied, for example threaded bars 7b, which hold it by means of plate 7c interposed among the spokes of the wheel itself and fastening wing-nut 7d.
  • a preferred embodiment (figure 5) is provided in which the member for the fastening of the load to lifting arm 1 is made up of strut 9 that carries several pairs of connections 9a and 9b capable of engaging with the frames of the vehicles to be loaded, pivoted in its intermediate point 9c on the end of lifting arm 1.
  • supplementary arm 10 hinged at its ends respectively on one end 9d of above mentioned strut 9 and on the support member so as to constitute the structure of a pantograph which maintains the strut itself parallel to itself over the entire transfer trajectory of load 4.
  • the fastening points of the above mentioned ends are selected so that the above mentioned springs, in the course of rotation arc 5 made by lifting arm 1 to transfer the load from the lower level to the higher level, exert a traction whose right line of application is such that it contrasts its rotation for a first part 5A of the arc, and it favors it for the remaining second part 5B, so as to reduce the effort in the phase in which it is the heaviest.
  • elastic rod 32 or an equivalent member anchors the device against capsizing.
  • One particular embodiment is finally provided for the event of the transfer of loads which for any reason may have to be able to rotate around their own vertical axis, as for example a marine outboard motor which has to be lowered from a boat or from a dock with a higher level, toward the transom of the craft onto which it is to be used or vice versa.
  • the support member of the device is framed with vertical development 17 and is equipped with means 18 ⁇ capable of connecting it to another vertical structure 19, for example the frame of the bulwark of a hull.
  • the rotation of lifting arm 1 is obtained by exerting traction on its mobile end lc by means of rope 20 and a system of pulleys 21 capable of reducing the effort needed.
  • a similar device it is possible to carry out the haulage of a motor directly to its point of installation on a craft, by adjusting its vertical position and its adjustment around vertical axis of rotation S and by carrying out its fastening onto the craft itself while it is still supported by arm 1 of the device.
  • the operation of the device can be carried out manually, by providing a handle with a handgrip, or by the use of a motor, whether it be an electric motor with a push-button panel or else the motor itself of a means of transportation equipped with a suitable force grip.
  • a motor whether it be an electric motor with a push-button panel or else the motor itself of a means of transportation equipped with a suitable force grip.
  • Such embodiments which can be imagined in an obvious manner by an expert, are not represented.
  • the device if it is anchored to a fixed structure, can also be used as a simple mechanical lift.
