' 6 Claims. (ill. 248-445) This invention relates to book holders and more specifically to a novel support therefor which may be locked in a plurality of positions.

This invention is an improvement over my construction shown in US. Patent No. 2,834,149 and is adapted to hold magazines, sheet articles and the like as well as books.

The general object of the invention is to provide a novel holder or support for reading matter, in which a novel, simple and eflicient locking mechanism is provided to secure the holder in a selected angular position.

A further object of the invention is to provide'in a book support which comprises a holder portion pivotally mounted on a leg structure for swinging about a generally horizontal axis, a novel locking means comprising a spring loaded bolt on the leg structure which is selectively entered into any of a series of apertures in a part swingable with the holder portion to hold the holder portion in selected positions, one of the apertures being located. to hold the leg assembly and holder portion in folded position for compact storage and ease of shipping.

A further object of the invention is to provide a novel locking device between the holder and the support therefor such that the locking device is readily accessible and easily operated so that the book may be tilted to desired position while it is held in the holder without the necessity of removing the book, then adjusting the holder and then replacing the book within the holder.

More specifically, the invention comprehends provid ing the hinge flange of the holder portion with slots to serve as one locking element and utilizing a portion of one of the support legs as a mounting for the bolt in position to cooperate with the slots.

These and other objects and advantages inherent in and encompassed by the invention will become more readily apparent from the specifications and the drawings, wherein:

' FIGURE 1 is a right front perspective view of the book holder;

FIGURE 2 is an enlarged plan view taken substantially on the line 2-2 of Figure 1 with portions of the holder shelves broken away;

FIGURE 3 is a side elevational view with ken away;

FIGURE 4 is an enlarged cross-section on line 44 of FIGURE 2;

FIGURE 5 is a fragmentary sectional view taken substantially on line 55 of FIGURE 3; and

FIGURE 6 is a fragmentary side elevational view of the device in folded position.

Describing the invention in detail and having particular reference to the drawings, there is shown a book holder generally designated 2 comprising a holder portion 3 and a supporting leg assembly 4. The leg assembly comprises front and rear bail-

type leg structures

5 and 6. The rear leg structure 5 comprises a bight portion 6' and generally

parallel side portions

7 and 8 projecting upwardly'and forwardly as seen in FIGURE 1 from opposite ends of the bight portion 6' which is provided with suitable spaced sleeves 9' and 18' of rubber or other nonmarring material for seating upon any suitable supporting surface such as a table or the like.

18 and 19 of the front leg structure 6. The

elements

18 and 19 merge at their lower ends into opposite ends of the bight element 24 of leg structure 6. The bight element 20 is also provided with rubber or

plastic sleeves

21, 21 which is adapted to engage the support surface such as a table or the like. 7 I

It will be noted that the

distal edges

22, 33 of the

side elements

18 and 19 are rounded and concentric with the axis of the pins 13 and 14 to accommodate passage of the

locking lugs

24, 25 which extend from the ends 11 and 12 substantially normal to the planes of the

legs

18 and 19 and engage with their

forward edges

26, 27 to limit the angular spread of the

leg structures

5 and 6.

The holder' portion 3 comprises a generally rectangular body 30 which is elongated axially of the pivot axis of the leg structures and spans the space between the pivots 13 and 14. The body 30 has an upright front wall with rearwardly directed

end flanges

32, 33 which arepivoted re:

spectively on the pivots 13 and 14 outwardly of the leg structures. The front wall has a pair of upwardly projecting book or

article holding tabs

34, 35 which oppose and cooperate with

backing plates

36 and 37 which are mounted on

parallel arms

38, 39 and 40, 41 respectively, by means of

pivot pins

42, 43, and 44, 45.

The

pins

42, 43 extend vertically through the outer ends of the

arms

38, 39 and through top and

bottom flanges

46, 47 of a bracket 48 which is formed integral with the lower edge of plate 36. The

flanges

46, 47 are disposed respectively above and below the

arms

38, 39 and are interconnected by a vertical rear wall or web 50 which is disposed behind the

arms

38, 39. Similarly pins 44, 45 extend vertically through the outer ends of

arms

40, 41 and through top and

bottom flanges

51 and 52 of bracket 53 which is formed with its top flange 51 integral with the lower edge of plate 37 and extends rearwardly therefrom. The

flanges

51 and 52 are disposed respectively above and below the

arms

40, 41 and are interconnected by a vertical web 54 which is disposed behind the

arms

40, 41.

The lower edges of the

plates

36 and 37 are provided,

edge of a book which is fitted between the

tabs

34, 35 and the

plates

36,37.

The

backing plates

36, 37 are biased toward the

tabs

34, 35 to hold a sheaf of pages 58 or those of a book inserted therebetween, by a torsion spring 60 which has its coil portion 61 sleeved over an upright pin 62 which extends through intercalated portions of the inner ends of the

legs

38, 40 and through the bottom wall 63' of the body portion of the holder substantially medially between the ends thereof and through a centrally disposed lug 64 projecting rearwardly from the upper edge 65 of the front wall 31 of the body portion 30. The

end por tions

66, 67 of spring 60 react against the back sides of

legs

38, 40 urgingthem forwardly. The inner ends of

arms

39,41 pivot on an upright pin 68 which extends through the lug 64 and bottom wall 63. Thus the backing plates are carried on parallel arms and in moving toward and away with respect to the opposing tabs are held generally parallel thereto.

The hinge or end flange 32 has a rear edge 70 curved substantially concentric with pin 13 and flange 32 is provided with a plurality of slots 71 extending inwardly from edge 70. These slots 71 selectively receive a bolt 73 therein, said bolt being formed as an extension of the top wall 74 of a box-like body of spring latch generally designated 75.

The latch 75, in addition to wall 74 has side walls 76,

13 77 depending from wall 74 and a bottom wall 78 which extends from wall 76 to wall 77 and with the other walls provides an enclosure 79 for a compression spring 80.

The latch is sleeved over the side member segment 9 and has its inner side wall 76 slidably engaging the inner face 81 of portion 9. The spring 80 is disposed between portion 9 and the wall 77 and reacts between a seat 82 in the form of a flange 83 on an L-shaped bracket 84 which has itsother flange 85 secured as by welding to portion 9.

The spring 80 bears against a front wall 86 of the latch and urges the latch toward the hinge flange 32 engaging the bolt portion within the respective slots.

It will be noted that the seat 82 and wall 86 are not normally disposed with respect to the

parallel walls

76, 77 and that the spring 80 thus develops a lateral thrust on the latch whereby the front edge portion 87 of the inner wall 76 is biased inwardly of leg portion 9. This action is developed so that in the folded position of the device as shown in FIGURE 6 wall 76 is caused to releasably engage against the outer side 88 the side ele-.

ment 18 of the leg structure 6 while the bolt portion 73 of the latch extends into the top slot 90 in the upper edge 91 of the hinge flange 32.

The angularity of the

leg sides

7 and 8 causes the portions 92, 93 of these legs to fold into the plane of the body portion.

It will be noted that the portion 20 has forwardly projecting hooks 94 which serve as holders for a large copy.

From the folded position shown in FIGURE 6, the leg portion 6 is swung rearwardly against the resistance of the latch body 75 with the bolt portion 73 sliding edgewise in slot 90. The legs and 6 are positioned as shown in FIGURE 3 with the

lugs

24, 25

engaging edges

26, 27 of

legs

18 and 19 of part 5 as seen in FIGURE 2 and the latch body is pressed back to release the bolt portion from notch 90 and entered into any selected notch 71 disposing the

backing plates

36, 37 in any desired position. The book is entered between

plates

36, 37 and tabs 34, by manually springing the plates rearwardly. If angular adjustment of the book is required the user merely presses the latch body rearwardly with his thumb and then swings the book and holder portion about the pins 13 and 14 until the desired position is obtained. The latch is then released and the spring causes the body and bolt portions to move forwardly entering the .bolt portion into the appropriate slot 71. The outer and

inner members

5 and 6 are U-shaped supports and are fitted one within the other.

. Having thus described a preferred embodiment of the invention, it will be realized that various other modifications will now become readily apparent to those skilled in the art within the scope of the appended claims.
