Definitions

  • the present invention relates to a portable suitcase which can be converted into an armchair.
  • the object of the present invention is to solve the problems mentioned above by proposing a simple, light and practical portable system for carrying out oral care outside specialized establishments or dental offices.
  • the invention also aims to provide a portable system which can be used in a wide variety of fields of intervention, such as humanitarian missions and disaster medicine, military health services and medical assistance for sports events and communities.
  • the portable system consists of a convertible case provided with two semi-shells complementary to each other.
  • the two half-shells are mounted face to face to enclose a volume in which one can have for example an air mattress, a seat for the practitioner, small instrumentation ...
  • the two half-shells are separable and each provided on the back with an assembly means.
  • the first half-shells are first placed horizontally on the ground with its back facing upwards.
  • the second half-shell is then placed back to back on the first half-shell and assembled using the respective assembly means of the two half-shells.
  • An adjustment means is associated with the assembly means for adjusting the relative position of the assembled half-shells.
  • the second half-shell comprises a first element articulated around an axis located at one side of the half-shell and being able to be folded towards the inside and the outside of the half-shell, a second element articulated around a axis parallel to the first and located on the opposite side of it.
  • the assembly forms a chair whose base is constituted by the first half-shell and whose seat is constituted by the second half-shell completed by the two articulated elements unfolded as bearing surfaces for the legs and the patient's back.
  • the orientation and the inclination of the seat relative to the base can be adjusted by means of the assembly means and the adjustment means.
  • Means can be provided for adjusting the inclination of the articulated elements with respect to the second half-shell in order to be able to adapt the inclination of the backrest and the footrest of the chair.
  • an air mattress can be placed in its inflated state on the seat support surface, this mattress being able to be transported in its deflated state in the initial suitcase before being converted into a wheelchair.
  • Means for assembling the half-shells can be constituted by ribs and grooves, complementary to one another, provided on the respective backs of the half-shells.
  • the back of the first shell preferably has a depression, the shape of which conforms substantially to that of the back of the second half-shell, in order to better distribute the forces undergone by the half-shells, when a patient is lying on the armchair thus converted.
  • the adjustment means can be provided by a blocking device which can vary the friction between the joining means or block the joining means by an attached element.
  • the portable suitcase consists of a first half-shell 1 and a second half-shell 2, of complementary shape to each other, assembled face to face by enclosing a volume to contain Items.
  • the suitcase is substantially ovoid in shape and provided with a handle 3 on a lateral side of the first half-shell.
  • the first half-shell 1 has a depression 4 on the back, the surface of which is curved in the same way as the back of the second half-shell 2.
  • a longitudinal groove 5 is formed on the depression 4 of the first half-shell 1.
  • the groove 5 is of constant section and the width of the bottom is greater than the width of its opening.
  • On the back of the second half-shell 2 is provided a curved longitudinal rib 6, of shape complementary to the groove 5 of the first half-shell.
  • the suitcase is provided with other means, not shown, for holding together the two half-shells 1 and 2 and the opening of the suitcase like a conventional suitcase.
  • the second half-shell 2 comprises two articulated elements 7 and 8 mounted opposite one another around the parallel axes which are located on the two end sides of the half-shell 2.
  • the articulated elements 7, 8 are produced in the form of curved plates of determined length, so that in the folded position, they conform to the shape of the inner face of the half-shell 2, the two free ends 7a and 8a being located at the end tipped at the bottom of the inside of the half-shell 2.
  • the half-shells 1 and 2 are first separated. Then the first half-shell 1 is laid flat on the ground, the depression 4 of the half-shell 1 being oriented to the top. The second half-shell 2 is then placed with its back down on the depression 4 of the first half-shell 1, the curved longitudinal rib 6 on the back of the second half-shell 2 sliding inside the groove 5 of the first half-shell 1.
  • the half-shells 1 and 2 are thus assembled back to back with the possibility of changing the inclination of the second half-shell 2 with respect to the first half-shell 1 using the groove 5 and the rib 6.
  • the first articulated element 7 is then unfolded towards the outside of the second half-shell 2 to a limit position shown in FIG. 3, this limit position can be adjusted by an appropriate means not shown to change the inclination of the 'element 7 relative to the half-shell 2. It is the same for the second articulated element 8.
  • the articulated elements 7 and 8 may include locking means to strengthen their mechanical strength in the deployed position. This provides a support surface for receiving a patient lying on the chair.
  • the chair 9 thus obtained is used in combination with a soft mattress, such as an air mattress, so as to have a more comfortable patient reception surface.
  • a soft mattress such as an air mattress
  • This mattress may include handles on the lateral edges for carrying the patient.
  • the articulated element 7 may include an end portion 7b which can be pivoted so as to form an adjustable headrest support. As shown in FIG. 3, the articulated element 7 can serve as a support for a retractable and removable shelf 10 to allow the doctor to deposit his tools.
  • the inclination of the chair can be adjusted by means of the play between the rib 6 and the groove 5 provided on the back of the half-shells 1 and 2. This inclination can be locked in indeterminate positions using any known locking means in itself.
  • the first half-shell 1 may include a retractable base 11 as illustrated in FIG. 3.
  • a small telescopic lamp mounted on one side of the first articulated element 7 may also be provided. lighting necessary for the doctor's intervention.
  • the chair can be converted back into a portable suitcase in which the doctor takes all his instruments and the deflated air mattress. It thus considerably widens the field of intervention in the service of patients.
