ERGONOMIC SUPPORT FOR READING

Ergonomic support for reading

The subject of the present invention is an ergonomic support for reading documents or books, in particular during work on a computer workstation or in a reading room, designed for attachments to computer screen risers (monitor holders, platforms, supports), desks, tables, shelves, bookshelves, cabinets and other furniture. The computer has become a popular tool for working, used in libraries, reading rooms, schools, computer labs, offices and home offices. At all of these locations, computer usage should occur in accordance with the rules of ergonomics which help prevent scoliosis. During long-term work with a computer, the maintenance of a healthy, anatomically correct posture is requisite.

Polish patent description number PL. 179187 discloses a pulpit for reading and writing. This pulpit comprises a usable surface movably mounted on a base and a movable support with a support for books which forces one to assume a correct posture during reading and writing.

A supporting holder, particularly for books, known from Polish patent description PL. 178592 is characterized in that in the front part of the arms of the base there is a shaft. On the shaft there is a movably mounted, elongate supporting element, onto which on one side rod-like holders for books are mounted removably along its long axis, which are connected with transverse walls found at both ends of the element. In one of the transverse walls there is a blockade for the rod- like holders, and in the middle upper portion of the back wall of the base there is a friction delimiter of the variability of the position of the support (over an angle of 180 degrees) and apertures are made in this wall for mounting the supporting holder.

A pulpit for reading and writing known from patent description PLl 67069 possesses a usable surface, whose plane forms an angle with the horizontal plane of the base. Attached directly or indirectly to the usable surface is a movably mounted support in the form of a scaffold equipped with a support for books and possibly writing implements, wherein the usable surface is connected to the base with inclined mounting brackets.

Another pulpit for reading is known from Polish patent application P.327126, and has two brackets mounted onto an inclining plate along its sides, in which are set movable sliders with handles. A board with a support is attached to the sliders. The board possesses two lengthwise perforations through which are threaded elastic elements which attach the book, and the brackets are equipped with indentations for setting the position of the board. To the sides of the base there are attached sliding and rotating legs, and the bottom of the base is finished with a material increasing the friction coefficient.

A stand for holding books during reading is known from Polish patent application P.292268, and has a multipartite arm comprising a first arm and a second arm interconnected via a rotating coupling. On one end of the arm is a first rotating coupling connected to the folding support. The second end of the arm is equipped with a third rotating coupling to which is attached a mounting apparatus for mounting on a base in any orientation. The stand is designed to hold books or notes in any chosen conditions.

A corrective pulpit for reading and writing is known from Polish utility model PL63983, and has an element in the form of an L-beam with two arms attached to the upper portion of the scaffold. The edge of the usable surface is superimposed on one of these arms and forms a trough between the edge of the usable surface and the second arm of the L-beam. The bottom part of the support has a movably mounted footrest. In school conditions, this pulpit ensures the correct posture of the user, preventing scoliosis.

An ergonomic universal pulpit known from Polish utility model PL.114070 has a base of the pulpit made of a board or particleboard, to which a usable surface is attached, interconnected with a furniture hinge. A lath is attached to the usable surface at an angle of 60° in order to keep book pages open. The lath is also attached to the usable surface with a hinge. When the pulpit usable surface is being written on, the lath is kept closed using magnetic locks. The base and usable surface are prevented from opening during pulpit transport by a magnetic lock. The usable surface is maintained at a desired angle by a single friction lock or on both sides, in the case of pulpit formats larger than ordinary.

Another book support is known from Polish utility model application PLl 12245. The support is made of laths constituting the main frame and supporting part. A book can be set into several positions/inclinations as appropriate to the placement of the reader's eyes with the aid of a wire frame. The pages of the book are prevented from closing by appropriate pegs and, additionally, a spring. The support can be mounted permanently to a desktop through suction cups or circles of mounting tape. Books of any format can be placed on the support.

A reading pulpit described in Polish utility model application PL103339, comprises a rectangular portion hinging transversally at three points. The element joins a portion of the pulpit with its after wall, forming an angle of 45° between the part and the plane of the horizontal base through the selection of the appropriate length of this element. These elements join a portion of the pulpit with the part, at the same time maintaining the part in a position facilitating the retention of the text from the bottom. Attachments make it possible to detach the elements and collapse the pulpit.

An ergonomic support for reading according to the present invention is made in the form of a mobile pulpit mounted such that it is mobile in a sliding and rotating motion through at least one positioning element with at least one mobile element of a mounting guide. In the support, the positioning element is set into the mobile element of the pulpit guide, and this element in the immobile element of the pulpit guide located in a wall of the pulpit, preferably its lateral wall. Preferably, an elevation regulator is set into the mobile element of the pulpit guide, which determines the positioning elevation of the mobile pulpit, and which cooperates with the positioning element. Preferably, a regulator of the inclination of the mobile pulpit is set into the mobile element of the pulpit guide, which cooperates with the positioning element. Preferably, the positioning element is in the form of a half-circle, on whose perimeter there is an arc-like indentation for the regulator of pulpit inclination, and near its diameter there is a perforation for the elevation regulator. Preferably, a frame with catchments for documents is set above or in the upper part of the mobile pulpit. Moreover, in the support, the mobile element of the mounting guide is set into the immobile element of the mounting guide, mounted permanently near the reading area. In the support for the computer work station, the immobile element of the mounting guide is set into monitor support, whereas the monitor platform has a usable surface affixed on four legs with adjustable elevation. Preferably, there is a shelf supporting the read materials in the lower part of the pulpit.

The support makes it possible to place the document or book at an appropriate distance from the eyes, under an appropriate angle and an appropriate elevation. The regulated positioning of the pulpit makes it possible to greatly increase the working comfort, particularly with a computer, without undue stress on the muscle, skeletal and visual systems. The support fulfils the ergonomic requirements of adapting a workplace to the anthropometric characteristics of the user.

The subject of the present invention in an example embodiment is shown in the figures. Fig. 1 shows the positioning element set into the mobile element of the pulpit guide set into the lateral wall. Fig. 2 shows the positioning element set into the mobile element of the pulpit guide set into the back wall. Fig. 3 shows the pulpit in lateral view, and Fig. 4 shows the ergonomic support for reading mounted on a support for a computer monitor seen from the front.
