Description

  The present invention relates to an auxiliary support that can be coupled to a wheelchair, chair, bed, or the like.

  In some places, for example, in classrooms and conference rooms, the chair on which an attendee sits must have a service tray. This tray allows attendees to take notes on paper or electronic equipment, for example.

  It is obvious that the chair with this service tray has the disadvantage of taking up too much space because the tray is not used continuously.

  In order to solve these drawbacks, chairs having a tray that can be placed in a use position and a folding position are known. However, the mechanism that enables folding of the tray is complicated, and the cost of the chair is increased. .

  Another disadvantage of such chairs is that they are not modular because they are not designed to join other accessories.

  In other situations, it may be beneficial to provide a service tray on a wheelchair or bed, for example, to place the article where the user can easily reach.

  The need for an auxiliary support comprising a tray for a wheelchair, chair or bed, for example, which can be mounted in a removable manner and placed in place in a simple and economical manner is therefore self-evident. .

  The auxiliary support of the present invention solves the above-mentioned drawbacks and has other advantages as described below.

  The auxiliary support according to the present invention includes a substantially vertical arm and a substantially horizontal arm connected to each other, and an auxiliary element mounted on the substantially horizontal arm, and the substantially vertical arm is a bearing surface for the substantially horizontal arm. It is characterized by including.

  The substantially vertical arm advantageously includes a connecting element with a hinge at its upper end, and one end of the substantially horizontal arm is connected to this hinge.

  The connecting element is preferably mounted rotationally on the substantially vertical arm and includes a blocking element for blocking the rotation of the connecting element relative to the substantially vertical arm. This block element further allows complete separation of the substantially vertical arm, which is a great advantage for the transport of the auxiliary support of the present invention.

  According to a preferred embodiment, the substantially vertical arm includes at least two telescopic bars.

  The auxiliary support further includes an auxiliary element that is pivotally mounted to the substantially horizontal arm.

  It is advantageous if the substantially vertical arm further comprises, for example, a wheelchair, chair or bed, or a coupling element for coupling the arm to the lower end as a complement.

  With the auxiliary support according to the invention, auxiliary elements which can be coupled to wheelchairs, chairs, beds, etc., such as trays, are held in a stable position by the bearing surface and can be used in a simple and economical manner.

  Still further, as a result of the great freedom of movement of the support, the position of the tray can be changed and adapted in a comfortable manner.

  For a better understanding of what has been described above, attached is a drawing schematically illustrating a practical embodiment as a non-limiting example only.

1 is a perspective view of an auxiliary support according to the present invention in a use position.

  FIG. 1 shows an auxiliary support according to the invention, identified in its entirety by the reference number 1, in use.

  The auxiliary support 1 includes a substantially vertical arm 2 and a substantially horizontal arm 3 which are connected to each other by a hinge 6 so that the substantially horizontal arm 3 is to the left with respect to the substantially vertical arm 2 (according to FIG. 1). Can be rotated.

  The upper end of the generally vertical arm 2 defines a bearing surface on which the generally horizontal arm 3 is supported, so that the arm is stably maintained in the use position without having to fasten or adjust any accessories.

  The hinge 6 is preferably mounted on a connecting element 5 that is mounted rotationally on the upper end of the substantially vertical arm 2.

  The generally horizontal arm 3 includes an auxiliary element 4 near one of the ends, which is a tray in the embodiment shown in FIG. 1, but the tray is any suitable element, such as a coaster, stand, etc. Also good. This auxiliary element 4 is advantageously pivotally mounted on the substantially horizontal arm 3.

  The generally vertical arm 2 further includes a coupling element 8 at the lower end that can couple the auxiliary support 1 to a wheelchair, chair, bed, etc., for example. This coupling element 8 is rotatably mounted on the substantially vertical arm 2.

  In order to allow height adjustment, the substantially vertical arm 2 is formed by two or more telescopic bars, one of which is housed inside the other.

  The blocking element identified by the reference numeral 7 since it performs the same function and is substantially the same has been devised to block the movement of the various components of the auxiliary support 1 according to the invention.

Specifically, these block elements 7 are:
Between the auxiliary element 4 and the substantially horizontal arm 3 to block the pivoting of the auxiliary element 4;
Between the connecting element 5 and the substantially vertical arm 2 to block the rotation of the connecting element 5;
Between the two telescopic bars of the substantially vertical arm 2 to block the relative movement,
Between the coupling element 8 and the substantially vertical arm 2 to block the rotation of the substantially vertical arm 2;
Installed.

  These block elements 7 can be easily released by rotating them. Movement of the various components relative to each other is possible upon rotation and only needs to be rotated in the opposite direction to re-block the components relative to each other. The block is implemented by suitable means, for example by a cam that is pressed against one of the accommodated arms 2, 3 in the block position.

  The blocking element can separate the components of the auxiliary support to facilitate transportation.

  Reference has been made to specific embodiments of the invention, but it has been noted that the auxiliary support described may be subject to variations and modifications without departing from the scope of protection defined by the appended claims. It will be apparent to those skilled in the art that all the details can be replaced with other technically equivalent details.
