This invention relates to an attachable and detachable book support adapted to be associated with opera, chairs, auditorium chairs, and the like, and in which means are provided for detachably securing an arm for writing or support purposes onto the conventional arm of an opera chair, and the like.

Many times it is necessary, due to crowded conditions in school, to hold classes in auditoriums and assembly halls where the chairs are not suitable for the taking of notes since the students have no place on which to support their note books. By providing a support which can be quickly attached to or detached from an arm of an opera chair, these opera chairs can be thus equipped to convert an auditorium into a class room.

It is an object of this invention to provide means attachable to an arm of an opera chair and the like, whereby a book support and the like can be provided, and said attached arm being jointed, if desired, so that the forward end can be adjusted at any desired angle; or, if desired, in order to permit ingress and egress between the seats, the forward end of the support can be raised to vertical position or slightly off-centered position, so that it will stay in this raised position while persons are moving along the aisles between the seats, and which can be folded downwardly to occupy a substantially horizontal position with relation to the other portion of the support, which is attached to the arm of the opera chair.

Some of the objects of this invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which:

Figure l is a top plan view of a portion of an opera chair, and showing my invention attached thereto;

Figure 2 is a side elevation looking from the lower side of Figure 1;

Figure 3 is a vertical sectional View taken along the line 3-3 in Figure 1;

Figure 4 is a sectional View taken along the line 44 in Figure 1;

Figure 5 is a vertical sectional view taken along the line 55 in Figure 2.

Referring more specifically to the drawings, the numeral I0 indicates one of the two side frames of an opera chair which usually has a seat H pivoted as at 52 and folding to vertical position or to horizontal position when it is to be occupied. These opera chair frames ill have secured thereto suitable brackets l3 to which are secured a back I4. On top of the frames it) are usually secured a conventional arm [6 to thus complete the opera chair. In order to convert this opera chair into a student chair having a book support, I provide a board-like member attachable thereto, and which can be all in one piece or made in two sections and pivoted together if desired. In the present form of the invention, I provide a board member 20 which can be of wood, plastic, aluminum, or any other suitable material, This member 20 has, preferably, a felt or other suitable pad 25 secured to the lower side thereof to rest against the upper surface of the arm It. To the rear end of the member 2!) is secured a bracket 22 which has two forwardly projecting

side lugs

23 and 24, and a lower lug 25, fitting beneath the rear end of the arm 46. This member 20 also has secured to the lower side thereof, by any suitable means, such as screws 21, an inverted U- shaped bracket 28, which has downwardly and inwardly projecting

spring arm portions

29 and 29, which are adapted to fit on opposed sides of the arm It, to clampingly engage the arm and to hold the member 28 onto the arm in a rigid manner and yet which is detachable therefrom when upward pressure is applied to member 20.

The member 20 can extend forwardly to provide a broad portion for supporting a writing pad, book, and the like, but where this detachable arm member is to be secured to opera chairs which do not have a wide aisle therebetween, it is preferable to make the support in two sections, and in whichl provide the forward portion 30 thereof separate and hinged to the portion 20 by means of suitable hinges 3| and 3|, which can swing upwardly and which are imbedded flush with the upper surface of the

portions

28 and 30, and the proximate ends of the portions of the members 26 and 30 serve as a stop for the two portions to hold them in horizontal position. If desired, an additional stop and support can be provided in the form of an L-shaped bracket 32 secured to the lower surface of the portion 20 by means of suitable screws 33, and the downwardly projecting legs of L-shaped member 32 is adapted to be contacted by a screw 34 threadably mounted in the downturned leg of another L-shaped bracket 35 secured to the lower surface of member 30 by means of suitable screws 36.;

These L-

shaped brackets

32 and 35 in association with the screw 34 form a better stop than the proximate ends of the

members

20 and 30 would provide, and in addition, they provide means for adjusting the angularity of the por-- tion 30 with relation to the portion 20. If desired, the screw 34 can be turned in one direction to raise the portion 3!! upwardly to, say, the first dotted line position in Figure 2, closest to the horizontal position, and when not in use and for purposes of allowing the students to pass freely between the rows of opera seats, the portion 30 can be moved up past dead center to the highest raised dotted line position shown in Figure 2.

It is thus seen that I have provided an arm or support attachable to an arm of an opera chair which will support writing pads, books, and the like, and which can be quickly attached to the chair and quickly detached therefrom in case it'- is not desired to be used, and which can have its forward portion folded upwardly, if desired, to permit ingress to and egress from the opera chairs, and which can also be adjusted to suit the individual desires of the occupant as to angularity of the forward portion.

In the drawings and specifications, there has been-setvforth' a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only,'and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim: 1. A- detachable book support adapted to be supported by the armofan opera chair, comprising a planar member, having a bracket at its rear endprovided with a plurality of projections adapted to fit around the rear end of the'arm of theopera chair and against its two sides and the lower surface thereof, and having an inverted U- shaped member secured to its lower side in spaced relation to the. bracket on the rear end thereof and adapted to clampingly engage the opposed sidesof the arm of anopera chair and to rest on said arm.

2; A detachable support adapted to be supported by the arm of an opera chair, comprising a planar member, having a bracket at its rearv end provided with a plurality of projectionsadapted to fit around the rear ends of the arm of the opera chair and against its two sides and the lower surface thereof, and'having an inverted U- shaped member secured to its lower side in spaced relation to: the bracket on the rear end thereof and adapted to clampingly engage the opposed sidesofi the arm of an opera chair and to rest on said arm, the forward portion of said detachable planar member being, separated from the portion resting'on the arm of the opera chair, and beinghinged thereto so that the forward portion can be folded upwardly out of the way when ingress and egress arev desired to the opera chairs.
