Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the invention [0001]
  • The present utility model refers to a support or LECTERN for books, notebooks, magazines or similar that has been IMPROVED in relation to the Portable and Adjustable Lectern Utility Model 654, due to the addition of elements to increase the lateral stability, prevent torsion efforts on the joint, increase the support area, varying the inclination angle of the aperture of the book, compensate for the differences in weight and volume between the sides of the books according to the page being consulted, hold the pages in six different points to choose from; elements which due to their characteristics of form, volume, materials and the relationship between them, make the apparatus portable, adjustable and resistant. [0002]
  • 2. Background of the Invention [0003]
  • THE “PORTABLE COMPENSATORY LECTERN” part of the “PORTABLE AND ADJUSTABLE LECTERN” (utility model 654 in Mexico) or COMPACT READING APPARATUS (U.S. Pat. No. 5,918,907 in USA) which can modify the inclination angle of the Book between 0 to 22 to 90 degrees in relation to the working table according to the reader's election; hold pages between 1 and 75 mm; and for its characteristics of form and manufacturing its resistant and easy to transport. [0004]
  • Within the scope of the models of Lecterns, the existing designs present a fixed angle of aperture, either completely opened (180°) or partially opened (135° approximately), moreover they lack of a compensating system for volume and weight according to the text page of the Book being consulted. [0005]
  • The supports for the lower edge of the Book are voluminous and fixed [0006]
  • There exists a lectern with Canadian patent that supports on the upper and lower part, but the constitution and movement of its parts are sufficiently different. [0007]
  • SUMMARY OF THE INVENTION
  • The present utility model refers to a Portable Compensatory Lectern that allows the modification of the inclination angle of the Book in relation to the supporting surface; variation of the aperture angle between the plane of the pages; compensate the differences in weight and volume between the sides of the open book, to stabilize it against lateral movements and to prevent the cutting effort on the seam due to the weight of the book; hold the pages in four points controlled independently or two dependent ones, that allow you, according to the book's characteristics, to use one, two, three, four, or up to six holders whatever results more convenient. Its manufacturing characteristics and the shape of its constitutive parts, makes it portable.[0008]
  • BRIEF DESCRIPTION OF THE DRAWINGS

  • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 and 2, a preferred embodiment of the Portable and Compensatory Lectern is shown: [0017]
  • Frame of the Portable and Adjustable Lectern ([0018] 1) of the technique's state.
  • Supporting Arm for the pages in the base of the Portable and Adjustable Lectern ([0019] 2) of the technique's state.
  • Base of the Portable and Adjustable Lectern ([0020] 3) of the technique's state.
  • Frame of the Portable Compensatory Lectern ([0021] 5).
  • Supporting Sleeve for pages in the base of the Portable Compensatory Lectern ([0022] 6).
  • Base of the Portable Compensatory Lectern ([0023] 7).
  • Inclination regulating Bolt of the Portable Compensatory Lectern ([0024] 8).
  • Volume Compensating Sleeve ([0025] 9).
  • Weight Compensating Sleeve ([0026] 10).
  • Traveling Supporting Sleeve for pages ([0027] 11).
  • Auxiliary Sleeve ([0028] 12).
  • Coupler ([0029] 13)
  • The Portable Compensatory Lectern comprising of a base ([0030] 7) that on its front presents a foldaway page holder (6); an M-shaped frame where the Books or similar rest, which is also foldable and is united to the base (7); the M-shaped frame presents an inclination regulating bolt (8), which can be slided over the M-shaped frame and allows the Lectern to adjust itself to the desired inclination; characterized because the two longer and parallel sections of the M-shaped frame (5) are joint together by a pair of couplers (13), the volume compensating sleeves (9) which are two sleeves that define a rectangular frame with circular cross-section as shown in FIG. 2 which by means of a hinge movement compensate the difference in volume that appears on either side of the book that is leaned on the Lectern as shown in FIG. 3, there's also the possibility of modifying the aperture angle of the book by moving both opposing ends to its joints with the M-shaped frame while turning them towards the book in tends to close, whereas in the opposite direction, tends to open up to a maximum of 180 degrees as shown in FIG. 4, as a third possibility, when put parallel to the frame (5), it allows to broaden the support area so that when a magazine is laid on it, it doesn't bend at the upper corners as shown in FIG. 5, and as proposed they're built of a strip of polished steel, that allows it to be compact and resistant, but they can also be made of wood, plastic or any other material that allows the movements and the mechanical resistance to the efforts made under normal or a exceeded manipulation of the parts. A pair of first “L” shaped sleeves are joint together articulately by couplers (13) to each volume compensating sleeve (9) at the longer section of the L-shaped sleeve and remain located at both ends of the longitudinal section opposed to where the volume compensating sleeves (9) and the M-shaped frame (5) are joint together. This first L-shaped sleeves sum up a total of four, two lower ones, one for each volume compensating sleeve (9)also called weight compensating sleeves (10), keep the book in equilibrium and prevent it from suffering damage due to torsion given that on them rests the lower part of the book, giving them support as shown in FIGS. 3, 4 and 6; and two upper ones which are auxiliaries for support, also called auxiliary sleeves (12), both weight compensating sleeves and auxiliary sleeves have the same shape, a steel rod of circular cross-section, which is bent at 90 degrees forming an “L” with different length between its sides, they also could be made of wood, plastic or any other material capable of resisting efforts due to the weight of the biggest book for the Lectern or due to reasonable exceeded manipulation, as shown in FIGS. 2, 5 and 7; a second group of four L-shaped sleeves, called traveling supporting sleeves for pages (11) as shown in FIG. 2, are joint together by its longer section to each one of the weight compensating sleeves (10), and two auxiliary sleeves (12) by its short section and free in an articulate way by means of couplers (13), what allows a longitudinal and hinge movement, with this adjust itself to the width of the book and allow the holding of the pages that remain frontal, of the book that's rested on the lectern once it's opened as shown in FIG. 6. The material to be used to manufacture these traveling supporting sleeves for pages (11) can be steel, plastic, wood or any other material able to resist the mechanical efforts due to normal or reasonable exceeded manipulation of the Lectern. The couplers (13) which purposes are to joint together the different parts of the Lectern have also the purpose of allowing an articulate movement that is sort of difficult between two pieces, therefore they are built with two materials, a plastic part with a high friction coefficient that can resist impacts with a rectangular parallelepiped shape and with two parallel grooves where the rods of the different sleeves to be assembled will be stored, and a part in shape of a staple of a material resistant as steel which purpose will be that of embracing the plastic part, what will give it resistance, reliability and little volume to the assembly.
