Definitions

  • the object of the present application is to provide a collapsible armrest device for stretchers, as well as a stretcher provided with said device.
  • the invention proposes the development of a collapsible armrest device for stretchers of those used for physiotherapy, osteopathy, chiropractic and the like, which have a mechanism that enables the adjustment thereof to support the arms of the patient.
  • Stretchers used for physiotherapeutic treatments which have multiple adjustment mechanisms to make it easier for the therapist to perform treatment on a patient are well known.
  • the present invention has been developed with the aim of providing a collapsible armrest device for stretchers which is configured as a novelty within the field of application and solves the aforementioned drawbacks, further contributing other additional advantages which will be obvious from the description below.
  • An object of the present invention is to therefore provide a collapsible armrest device for stretchers comprising a support base intended to be coupled to the frame of a stretcher, a pair of armrest surfaces arranged on both sides of the support base, and a drive mechanism intended to move the two armrest surfaces from a first position to a second position, characterised in that the drive mechanism has a parallelogram articulated mechanism that has a plurality of bars extending from the support base, which are rotatably articulated at one end to the support base while the opposite end is articulated to corresponding plates that are linked to the armrest surfaces, opposite bars being linked to a respective plate articulated to each other, such that the movement of the two plates is carried out in a synchronised manner.
  • the two armrests are moved by means of a mechanism that is simple to manufacture and easy to handle by the user, so that the manufacturing costs thereof are lower. Also, it should be noted that the movement made by the plates of the armrests from the lower to the upper position, or vice versa, is practically vertical, such that it is not uncomfortable for the user in the case of having the arms placed on the armrest.
  • the device includes a damping means linked to the aforementioned interlocking means, which has a manually driven ratchet, the movement of which frees the movement of the bars.
  • a damping means is arranged, preferably a pneumatic piston cylinder that is fixed to the support base at one end and the opposite end thereof is fixed to one of the two plates. This piston cylinder is compressed and decompressed depending on the desired position.
  • Another object of the invention is to provide a stretcher for physiotherapy, osteopathy, chiropractic and the like, which comprises a main frame that has a support structure having at least one horizontal resting platform, comprising an armrest device coupled to the support structure.
  • the horizontal platform has at least one support region for the head of the user and a second adjacent region, the width of the support region being less than the width of the adjacent region, such that it defines two empty side regions intended for the arrangement of armrest surfaces. In this way, the armrests do not protrude the full width of the stretcher.
  • the collapsible armrest device that is described represents an innovative structure with structural and constituent features heretofore unknown for its intended purpose, reasons which, taken together with its usefulness, provide it with sufficient grounds for obtaining the requested exclusivity privilege.
  • the collapsible armrest device for stretchers essentially comprises a support base (1) intended to be coupled to the frame of a stretcher, a pair of armrest surfaces provided with pads (2) for arranging the arms of the patient to relax the neck and shoulder muscles, which are arranged on both sides of the support base (1) and a drive mechanism intended to move the two armrest surfaces from a first position to a second position, the positioning of which will depend on the treatment of the user or patient.
  • the support base (1) is made of metal and has a main body (10) with a substantially Y-shaped longitudinal cross section provided with two flat regions (11) with a plurality of through holes (12), which are intended to be crossed through by screw elements (not shown) intended to be fixed to a portion of the frame of the stretcher, generally indicated with reference (3), with the arrangement of holes and screw elements acting as fastening means.
  • each set is made up of two bars (4), are rotatably articulated to the support base (1) at one end by means of axes (6) while the opposite end is articulated by means of second axes (7) to corresponding plates (5) that are linked to the armrest surfaces.
  • Opposite bars of each set linked to a respective plate (5) are articulated to each other by means of an attachment bar (8) of shorter length, such that the upward and/or downward movement of the two plates (5) is carried out in a synchronised manner.
  • Each of the plates (5) has a first section (50) in an inverted "U” shape and a second flat section (51) provided with a plurality of through holes (52) intended to be crossed through by screw elements (not represented) intended to be fixed to the pads (2) in a manner known per se, such that no more detail will be provided in the description thereof.
  • an interlocking means that has a ratchet (9) easily accessible to the user, the movement of which frees the movement of the bars (4).
  • a pneumatic piston cylinder (13) is provided which is fixed to the support base at one end and the opposite end thereof is fixed to one of the two plates, the cylinder being linked to the ratchet (9) for compressing and decompressing the pneumatic piston cylinder (13).
  • Figures 4 and 5 show a stretcher (3) for therapeutic treatments comprising a main frame that has a support structure (30) resting on a base (31) that has a horizontal resting platform (32).
  • the horizontal platform (32) has at least one support region for the head of the user (33) and a second adjacent support region, the width of the support region being less than the width of the second adjacent region, such that it defines two empty side regions intended for the arrangement of the two armrest surfaces with the pads (2), so that the armrests do not protrude from the perimeter defined by the horizontal platform (32) and do not represent an obstacle.
