Abstract

Device for manually lifting a load such as a cart, suitcase and the like, making it easier to ascend and descend staircases and various obstacles. The device has a first part comprising a frame secured to wheels, and handles being fixed to the frame. A second part comprises a load support secured to the wheels and a load being mounted in a fixed manner on the load support, the second part being able to slide with respect to the first part by the action of a telescopic lever arm in order to ascend a step of a staircase in two phases, the telescopic lever arm being fixed to the handles by a first articulation, a second articulation connecting the telescopic lever arm to a transmission which is in turn connected by a third articulation to the load support of the second part.

Description

  • The present invention relates to a device for manually lifting a load with a lever for being used for a cart, a suitcase and the like.
  • Experience has shown that a user currently encounters difficulties when ascending and descending staircases and various obstacles with a cart or a suitcase.
  • The device of the invention, which solves these disadvantages, is remarkable in that the manual effort made by the user will be significantly reduced when ascending and descending staircases and various obstacles.
  • The present invention will be described in detail in the following with reference made to the attached drawings given only by way of example in which:
  • FIG. 1 shows a lateral view of a device according to the invention showing the confrontation of various steps at visible angles.
  • FIG. 2 shows a lateral view of the device according to the invention,
  • FIG. 3 shows a front view of the device according to the invention,
  • FIG. 4 shows a front view of the device according to the invention, and
  • FIG. 5 shows a front view of the device according to the invention with the largest load,
  • FIG. 6 shows a lateral view of the device according to the invention with the largest load and showing details of the embodiment.
    •
  • FIG. 1 shows that the device has two parts:
      • a first part comprising: a frame 1 integral with the wheels 2, wherein the wheels 2 and the handles 3 are fixed to the frame 1,
      • a second part comprising: a load support 4 integral with the wheels 5, the wheels 5 and a load 12 which is mounted in a fixed manner on the load support 4.
  • The second part can slide relative to the first part by the action of a telescopic lever arm 10. The action of ascending a staircase step with the device according to the invention is made in two phases in the following manner:
      • during the first phase by turning the telescopic lever arm 10 upward from an initial low position following a circular movement according to arrow F 1, wherein the second part slides upward relative to the first part and ascends a staircase step,
      • and then, during the second phase, by turning the telescopic lever arm 10 downward following a circular movement according to the arrow F2 until the initial low position of this telescopic lever arm, the first part ascends for its part onto the same staircase step.
  • The telescopic lever arm 10 is fixed to the handles 3 by an articulation 9. A second articulation 8 connects the telescopic lever arm 10 to a transmission 6 which is connected for its part by a third articulation 7 to the load support 4 of the second part.
  • FIG. 1 shows that during the phase 2, by turning the telescopic lever arm 10 downward according to arrow F to its initial low position the wheels 5 move the second part in a movement of translation according to arrows G-G′ so that the first part can reach an angle visible on the staircase edge in order to facilitate the ascent of the first part.
  • FIG. 2 shows that the device comprises a joining pin 13 with a spring 14 joining the frame 1 and load support 4 and allowing the device to move with its four wheels 2 and 5 on a plane surface.
  • Referring again to FIG. 1, it can be seen that the joining pin 13 is released by a cable 15 and rod 15′, allowing the load support 4 to move relative to the frame 1.
  • It can be seen in FIGS. 5 and 6 that the telescopic arm 10 is fixed to the frame 1 parallel to a removable load 12 which is greater, allowing the telescopic lever arm 10 to be turned up and down following a circular movement according to the arrow F without being hindered by the removable load 12.
  • The rotary handle 11, a user aid for manipulating the telescopic lever arm 10 according to arrow F, can be seen on all the figures.

Claims (3)

What is claimed is:
1. A device for facilitating movement of a load up a staircase, comprising:
a load support for supporting said load, said load support including at least one load support wheel;
a frame including a plurality of frame wheels; and
a lever arm connecting said frame to said load support, said lever arm being movable in a first direction to cause said load support to slide upward relative to said frame, and being movable in a second direction to cause said load support to slide downward relative to said frame, such that said at least one load support wheel is caused to move from a first step of said staircase on which said plurality of frame wheels is resting to a second step of said staircase above said first step when said lever arm is moved in said first direction, and said plurality of frame wheels are caused to move from said first step to said second step when said lever arm is subsequently moved in said second direction.
2. The device as set forth in claim 1, further comprising at least a second load support wheel integral with said load support.
3. The device as set forth in claim 1, wherein said lever arm is telescopic.
