Abstract

The invention concerns an improved lectern for presenting bound books, consisting in a device for receiving the open book with maximum security for its cover and optimal reading comfort. It consists of two plates (1) with a ledge (2) fixed by clamps (3) to pivoting pins (4). Said pins (4) are fixed on a crosspiece (5) whereof the upper profile constitutes a stop for the inclination (6) of the plates and houses springs (7) balancing said plates, a device (C) for extending the crosspiece (5). Said crosspiece (5) is fixed to lateral legs (8) by a system such as, for example, perforations and bolts (9) for varying the lectern inclination from a horizontal plane to a quasi-vertical plane. The legs (8) comprise recesses (10) for receiving a mobile crosspiece (11) or console (12), fixed on either a central (13) or lateral (14) column. In the latter case, the height is adjusted by means of a rack (15) or a clamp assembly (16). To ensure a proper limit stop for the edge (0) of the book pages on the plate ledge (2), the usual slight extra width of the cover (17) is compensated by mobile inserts (18) maintained above said extra width (17) by a fold-up forming a corner angle piece.

Description

DESCRIPTIF
La présente invention concerne un dispositif élaboré de lutrin pour la lecture, compulsation, exposition de livres de formats et épaisseurs les plus variés assurant un confort optimum à l'utilisateur dans les meilleures conditions pour les ouvrage s. DESCRIPTION
The present invention relates to an elaborate lectern device for reading, examining, exposing books of the most varied formats and thicknesses ensuring optimum comfort for the user in the best conditions for the works.

Le lutrin est traditionnellement conçu comme un simple plan continu d'appui avec rebord formant butée, les deux faces de la couverture se trouvant en continuité de part et d'autre du dos, la surépaisseur de celui-ci dû à sa rigidité entraînant un bombement variable de l en- semble. Le dos du livre qui en est la partie la plus utilisable est excessivement sollicitée. Le dispositif selon l'invention permet de remédier à ces inconvénients.The lectern is traditionally designed as a simple continuous support plane with rim forming a stop, the two faces of the cover being in continuity on both sides of the back, the excess thickness of the latter due to its rigidity causing a bulging variable of the whole. The back of the book which is the most usable part is excessively stressed. The device according to the invention overcomes these drawbacks.

Dispositif formant lutrin pour présenter des livres ouverts en permettant une optimisation de la position de leur couverture. du dos et du dos de couverture dans des plans variables, assurant une honne planimétrie des pages exposées, caractérisé en ce qu'il comporte deux plateaux avec rebord frontal pour recevoir la couverture et le dos de couverture du livre , chacun des plateaux avec des étriers de maintien éventuels pivotant sur un axc dorsal, I'esp.acement entre eux assurant libre jeu au dos du livre, les deux axes étant solidaires dune traverse orientable, le dispositif étant complèté par des butées dc basculement des plateaux et des ressorts assurant leur équilibrare. Lectern device for presenting open books allowing optimization of the position of their cover. of the back and the back cover in variable planes, ensuring a good planimetry of the exposed pages, characterized in that it comprises two trays with front edge to receive the cover and the back cover of the book, each of the trays with stirrups holding any pivoting on a dorsal axis, the spacing between them ensuring free play on the back of the book, the two axes being integral with an adjustable cross-member, the device being supplemented by tilting stops for the plates and springs ensuring their equilibrare .

Dispositif de lutrin caractérisé en ce que la traverse est faconnée de manière que son profil supérieur limite la rotation des plateaux. Lectern device characterized in that the crosspiece is shaped so that its upper profile limits the rotation of the plates.

Dispositif en ce que sur la traverse - ou, selon une variante non dessinée, sur les axes dorsaux - sont fixés des ressorts déquilibragc des plateaux
Dispositif selon lequel les extrémités de la traverse sont asou- jettis par un système de réglage et blocage à des piètements. le lutrin pouvant ainsi être orienté de l'horizontale à la quasi verticale.Device in that on the crossmember - or, according to a non-drawn variant, on the dorsal axes - are fixed springs balancing the plates
Device according to which the ends of the cross-member are subjected by an adjustment and blocking system to legs. the lectern can thus be oriented from horizontal to almost vertical.

Dispositif caractérisé par des jambages permettant par une réservation appropriée l'adaptation d'un profilé formant lisse ou console pour fixation sur un support central ou latéral avec système de réglage en altitude par crémaillère ou étrier
Disposition non dessinée en ce que les étriers des plateaux peuvent comporter plusieurs positions de fixation
des axes dorsaux permettant de varier l'espacement des plateaux. Device characterized by legs allowing, by an appropriate reservation, the adaptation of a profile forming a smooth or console for fixing on a central or lateral support with altitude adjustment system by rack or bracket
Arrangement not drawn in that the brackets of the plates can have several fixing positions
back axes for varying the spacing of the plates.

Dispositif en ce qui concerne l'adaptation aux supports d'un système d'éclairage de l'ouvrage disposé sur le lutrin.Device with regard to the adaptation to the supports of a lighting system of the work arranged on the lectern.

Dispositif pour assurer une butée correcte de la tranche du livre sur le rebord des plateaux par des plaquettes mobiles formant cga- le ment rehausse, maintenues par un retour en cornière au dessus du débord habituel que forme la rive de couverture du livre. Device for ensuring a correct abutment of the edge of the book on the edge of the trays by movable plates forming also raised, maintained by a return in angle above the usual overhang that forms the cover edge of the book.

Dispositif caractérisé en ce que la traverse est constituée de deux parties reliées par un dispsitif formant coulisse. Device characterized in that the cross-member consists of two parts connected by a sliding device.

Dispositif caractérisé en ce que le ressort d'équilibrage est à lame prenant appui sur les deux axes dorsaux et formé de manière à laisser libre jeu au dos du livre. Device characterized in that the balancing spring is with a leaf resting on the two dorsal axes and formed so as to leave free play on the back of the book.
