Definitions
- the present invention relates to a portable table for wheelchair users, specifically for carrying out academic exercises, that is, writing, drawing, operating laptops, etc.
- the table basically consists of a main base made of a translucent material, preferably polycarbonate or acrylic, allowing users, who have lost the sensitivity of their legs, to be aware of their position so as not to generate pressure points. This is easily installed and removed from the back frame of the wheelchair
- the table of the present invention is characterized in that it is practical and when used, provides a feeling of independence and inclusion to the user.
- the table is safe and versatile to allow installation in the vast majority of manual wheelchairs. In addition to its high functionality it is accessible to any type of users, especially for students with limited financial resources.
- This accessory or table has the characteristics of having a specific dimension and is stored in the compartment provided under the arm of the chair, without having reduced these dimensions.
- This device represents a problem for the user since it can affect the mechanical and movement systems of the chair, exposing it to an accident, which is contrary to the objective sought with these technical aids, which is to provide security and confidence to the person sitting in it. In addition, it also restricts its usefulness to wheelchairs with armrests.
- US 6,450,570 relates to a removable wheelchair tray with an adjustable work surface, where said work surface has two parts or portions connected to each other by means of a hinge.
- the first part is a horizontal stationary support base and the second part is a movable upper portion that can be tilted at an angle that is in the range of 90 Q to 180 Q relative to the horizontal base.
- the system described in this document is based on the fact that the table can be folded in a sense that it is placed in front of the user, but does not allow the table to be folded to reduce its size and allow it to be stored more easily and compactly.
- WO 1987/005478 relates to a portable table for a wheelchair, which can be stored adjacent to the frame of the chair.
- the table is attached to the horizontal frame of the chair and includes a tilting device to vary the angle of the top of the table relative to the horizontal.
- the upper part of the table can also be slidably connected to the frame of the wheelchair thus allowing lateral movement.
- the table includes sections that can be folded and that are joined together by means of a magnetic retention device until the sections are separated by the user.
- the invention described in said document is based on the application of a kind of hinge or bending system which in this case is not a hinge as such, but is a magnetic joining device, which has the disadvantage of allowing
- the table can be separated relatively easily, even when the user needs it fixed in a certain place.
- it does not have its own arm rest and when carrying out academic activities such as fine and concentration tasks, if the wheelchair does not have the arm rest, it would have a disadvantage compared to other solutions as it does not have support for the forearm.
- the ergonomic table adaptable to wheelchairs, which is easy to use and installed in the wheelchair, so that when performing activities academics provide the student with a support surface to carry out these activities and at the same time that their aesthetics and form allow them to identify with the product. Additionally, it is necessary that the ergonomic table has a hinge system that allows it to be fixed in a suitable position for the student, guaranteeing the user a proper posture that avoids risk factors such as degeneration of the vertebral discs, possibility of ulcers in the lower limbs, fatigue in the back muscles among others found in this population.
- a need that is evident is the possibility of a table that can be fixed to wheelchairs that have or do not rest - arms and if the chair does not have any, that the table guarantees a postural support for the arm, given that in academic activities sometimes fine movements of the fine lines are required.
- the main need that exists in the state of the art is that it is required to transport the ergonomic table to any place, without the need to carry it installed in the wheelchair, but by the contrary, the user can install it only when You will develop academic activities. Therefore, the table is required to be portable, low weight and that can be folded into several parts to be stored or stored in a briefcase or backpack.
- Figure 1 corresponds to a lower perspective of the ergonomic table of the present invention.
- Figure 2 corresponds to an upper perspective of the ergonomic table of Figure 1.
- Figure 3 corresponds to a flat view of the lower part of the work surface of the table of Figure 1.
- Figure 4 corresponds to the exploded view of the ergonomic table of the figure
- Figure 5 corresponds to a detailed view of the attachment mechanism of the ergonomic table to the frame of the back of the wheelchair.
- Figure 6 corresponds to a general view of the ergonomic table of Figure 1 installed in a wheelchair.
- the ergonomic table (1) adaptable for academic exercises in wheelchairs, object of the present invention comprises the following elements or parts:
- An arm rest (3) which adapts to one of the sides of the wheelchair, depending on whether the user is right-handed or left-handed, who does not need the armrest (12) of the wheelchair (10) to be located.
- This arm rest (3) is attached to the work surface (2) by means of a hinge (31), which allows it to bend and the main surface (21) is located at the top of said.
- a coupling system (5) responsible for making the connection between the table (1) and the wheelchair (10) by means of the clamping mechanism (4).
- This coupling system (5) is located on the lower surface of the table between the main surface (21) and the arm rest (3).
- a connecting tube (6) which allows the connection between the table (1) and the wheelchair (10) to be made by means of the coupling system (5) and the clamping mechanism (4).
- the main surface (21) and the auxiliary surface (22) of the work surface (2) have housings (21 1, 221) that are located at the edge that makes the union between the two surfaces (21, 22), so that they can move up and down to rotate the auxiliary surface (22) and be able to locate it at the bottom of the main surface (21), as shown in the figure Four.
- the hinges (23) are safety hinges and move towards the same ends, in order to provide a fixed support to the user.
- These hinges (23) are attached to the surfaces (21, 22) by means of a series of screws, which securely fix them and prevent the auxiliary surface (22) from detaching from the table (1) during use and hit the user who is in the wheelchair (10) and stay on said surfaces in the spaces (212, 222) so that the "leaves" or flat part of said hinges (23) are at the same level of the surfaces (21, 22) and do not affect their movement.
- the main surface (21) has a pencil slot (213) to allow the user to store the pencils or pens he uses while developing an academic activity, without them rolling and falling from the table (one ).
- the work surface (2) is made of a translucent material, such as polycarbonate, PVC, glass or acrylic, which is also low and resistant.
- a translucent material such as polycarbonate, PVC, glass or acrylic
- Another preferred form may include the same opaque materials or include cheaper ones such as wood.
- the arm rest (3) has on its upper surface a hinge (31), which is installed on a minimum portion of the main surface (21) and on the surface of the arm rest (3), thereby allowing said piece to rotate without obstructing the movement of the other parts of the table (1).
- This hinge (31) allows the arm rest (3) to be folded over the upper part of the main surface (21), as shown in Figure 3, and thus provide portability to the table (1), complemented by the fold of the auxiliary surface, to be able to keep it in a briefcase or backpack.
- the mechanism for securing the chair (4) is composed of a lower support (41), which is fixed and does not allow the vertical movement of the table (1), a coupling structure (42) that is joins clamps (43) that surround the frame (1 1) of the back of the chair (10), so that the whole table can be fixedly attached to the chair (10) and screwed by means of a series of screws that are installed in the holes (431) to attach them to the coupling structure (42).
- the lower support (41) has a hole (41 1) which allows the joining of the connecting tube (6) to the clamping mechanism (4). This hole (41 1) has the same internal diameter as the external diameter of the connecting tube (6).
- This clamping mechanism (4) is installed on the back of the chair and remains fixed, which does not require disassembly when the user wishes to store the table (1) and move to another place or change activity to one in the that it is not necessary to use the table (1).
- This clamping mechanism (4) also allows the table to be rotated on the axis of the wheelchair's back tube (10) by placing the desk in a horizontal but rotated position. This function allows the user to clear the leg area any activity while still having functional the table stand to locate some objects. Also the rotation of the clamping mechanism (4) without the table (1) installed allows clearing the lateral area of the user and for example performing the thrust action of the wheels without the mechanism (4) bothering him and in a safe way.
- the coupling system (5) is attached to the main surface (21) by means of a series of screws (51) that cross said surface (21), in order to fix them two pieces and avoid undesirable movements of the table (1 ).
- This coupling system (5) makes it possible to make a connection between the work surface (2) and the clamping mechanism (4) that joins the chair (10), by means of the connecting tube (6), which it enters the clamping mechanism (4) at one end and the coupling system (5) at the other end.
- the coupling system (5) has a receiving hole (52), into which the tube (6) is inserted and adjusted by means of the screw (53) which passes through the hole (52) to its inner wall and fits into a series of slots (61) that are at the end of the tube (6) that is inserted into the coupling (5).
- the coupling system has two holes in the inner side face through which two pins (53) are inserted whose function is to fit in the slots (61) of the coupling tube (6) and allow when the coupling (6) attached to
- the table (1) moves vertically a suitable distance can rotate and place the table (1) horizontally.
- the grooves (61) of the tube ((6) have an arc greater than 90 ° allowing the table (1) when rotated and in an upright position to stay in this position and allow it to accommodate your legs or pick up fallen utensils.
