Description

The invention relates to a bed reading device with an articulated holding arm and adjustable bookplate to hold books, magazines or newspapers without the use of arms and hands to be able to read the printing units in a lying position, which can be folded down with one grip and over the bedside table can be swiveled aside next to the bed to take over the function of a bedside lamp when not in use.

The previously known devices for reading in a lying position in their basic concept, as well as in detail, are not designed in such a way that they can be used universally, for everyone Desires for convenient handling in practical use are sufficient and do not look like a technical, space-consuming foreign body in a bedroom furniture.

In detail, the known devices of this type are often too complicated and therefore not to be produced efficiently.

You have control elements with worm gear and gear drives, they have complex retaining rods and require special coil springs to compensate for their weight. After use they must be cleared away, otherwise they will be in the way when getting out of bed. They will rest over your head if the person is at rest, you can endanger them. The holding arms "often get in the way and the person lying down cannot stand move freely underneath. They cannot be placed at the head of the bed between the side bed frame and the bedside cabinet as the stand, which protrudes on all sides, cannot be accommodated here. The book plate with the The book is often not set in the most favorable reading position, but the person lying down has to be aware of the position of the book adjust. When reading lying on its side, the direction of the lines must be vertical in order to be parallel to the line connecting the two To be eyes, this book setting is usually not possible.

To turn the pages, the whole book often has to be moved or lifted become, which is awkward. Releasing, turning the pages and reattaching a book page is usually only possible with the help of

could take both hands, but operation is desirable with just one hand.

Previous devices are also often only for limited book formats and book thicknesses and do not allow magazines and newspapers to be attached.

The fact that new books cannot be opened flat because of their rigidity is not taken into account, but rather with Allow only a V-shaped opening and must therefore also be attached to the bookplate in this V-shape. Not enough attention is paid to optimal illumination of the reading surface to protect the eyes while reading with a glare-free light is necessary and therefore the right reading light becomes an indivisible component belongs to a reading device for the bed.

Furthermore, insufficient attention is paid to the important point of how to place the device on the bed and how to fix it therewith the holding arm carrying the book plate has a firm hold and can withstand the stress of heavy books.

The invention has set itself the task of the above Disadvantages of the previously known devices for reading lying down Fix position in bed.

An overall view of the bed reader, which is activated when it is used can be folded down to a small size and swiveled aside in order to then only take the puncture of a bedside lamp, Fig. 1 shows.

The articulated support arm carrying the book plate 3 a, 3 b consists of individual, e.g. four sub-elements 1 a, 1 b, 1 c and 1 d, which are connected to one another by joints 2 a, 2 b, 2 c with a vertical axis of rotation. This allows the long joint support arm to be buckled to a small extent, as shown in Fig. shows. The sub-elements come to lie one above the other in a vertical plane, they are covered by the book plate, Fig. 2.

In the exemplary embodiment, the joint is a threaded joint, i.e. it consists of a threaded cup 2a and a threaded washer 20 screwed together. Fig. 4 shows the threaded joint in section and its attachment to the sub-elements 1 a and 1 b of the joint support arm using screws like 22 a and 22 b with flat threaded pieces inserted into the square tubes 22 a and 22 b. The rotation takes place in the threads that also take the load. It is therefore a very stable one and easy to assemble articulated connection created. Also, no fastening screws can be seen from the outside, the joint has a pleasing appearance.

The last sub-element 1 d of the joint holding arm is about halfway as long as the sub-elements in front of it and again shorter than the width of the book plate. As a result, the book plate cannot see the folded joint holding arm from the front cover more visibly.

The ball joint 17 is attached to the sub-element 1 d via the threaded joint 2 d and a conical transition piece 28, which screwed with a splash 19 on the back of the book plate 3a is, Fig. 3.

The joint holding arm is with its first sub-element 1 a the protruding angle part 5 a of the sliding sleeve 5 screwed. The screwing is done in the same way as with that Threaded pot with a threaded flat piece inserted into the square tube 1 a from below through the angle part 5 a.

The height-adjustable sliding sleeve 5 on the column 6 can be held with a clamping screw K. An adjusting ring 7
secures the height adjustment when the clamping screw K to
Pivoting of the holding arm is released.

The column 6 is a square pipe section 9 »which is attached to a
Corner of the U-shaped stand 8 is inserted and fastened with a diagonally pressing screw 10.
To adjust the bookplate with the book attached to it in the direction and inclination desired for reading, e.g. also hanging over the front or with a vertical line when reading on the side, the column-like ball joint, which clamps very strongly but can only be operated with little force, is used 17. Fig. 5 shows a section through the ball joint. His flange 19 is with the part 3 a of
Book plate connected.

The ball 31 is pressed by the threaded spindle 24 via a pressure piece 25 against the spring snap ring inserted in a groove
pressed with a rectangular material cross-section.
The operating lever 18 is in a, to adjust the
Clamp with several threaded bores, cylindrical part 23 of the threaded spindle is screwed in and goes through a circumferential slot 27 in the housing. To cover the circumferential slot, a sleeve 26 is used, which rotates when the actuating lever is moved.

A conical transition piece 28 extends from the ball and is screwed to the threaded cup 2 d, as can be seen from the drawing is.

In the threaded pot, a threaded washer is screwed again, which in the manner already described with the sub-element 1 d of the joint holding arm is attached.

The one from a main part 3 a and a laterally extendable Part 3 "b of existing book board with one attached to it Book Fig. 6 and Fig. 7 show in front and top view.

With the part 3 b, two parallel guide rods 15 are fixed
connected, which are guided in the main part 3 a of the book plate in the holes 15 f.

3098 3 2/0171

With the part 3b that can be pulled out to the side, the book plate can be adapted to the size of the book or, for example, the daily newspaper. The guide is "clamped in" with the knurled screw 33.

The book plate has at right angles protruding, flat support strips 16 a and 16 b at the lower edge, the with elongated holes 17 a are provided for pushing through a retaining clip 34 to a particularly heavy book 37 when sloping forward Book plate possibly also to be attached in the manner shown in Fig. 10 by grasping the book cover 36.

The bookkeeping double fingers 12 a and 12 b consist of two leaf or flat springs, which at the end of a small column 14 u, which is guided and displaceable in a hole perpendicular to the book plate, are rotatably attached, they can be e.g. V-shape or on top of each other, Fig. 1, Fig. 6, Fig.

To attach the book to the book plate, place the double-leaf stick fingers between the pages of the book and press you with the book against the book plate and clamps the small column 14 u with the knurled screw 32 in the guide, like on fig. 6 and fig. 7 it is shown on the right. The bookkeepers can double-finger through the pull-out small pillars can also be used to take account of the changing Z-shape of the book at the beginning and end of reading by adding man.nur clamps the book cover between the book-holding fingers and pulls the small column 14 u forward as far as it can corresponds to the respective Z-shape of the book. Fig. 7 shows this function of the bookkeeping double finger at the beginning of the Book on the left.

Fig. 8 shows that a new, stiff book can only be opened in a V-shape to protect the cover the book plate can attach. To do this, pull out the small column with the double bookkeeping fingers and lets the book cover rest.

The blade holding fingers 13 a and 13 b, can be seen e.g. in Fig. and Fig. 7, consist of a leaf spring bent at the end to form a curve. The blade holding fingers are also rotatable on small columns 14, which in the same way as with the Buchhaltedpppelfingern in guide holes perpendicular to the

The surface of the Bach plate can be moved to adapt to the book thickness and can be clamped with a trading screw 32.

So that the bookkeeping and page holding fingers in every position, in if you turn it to stop, a rotation lock is provided in the manner shown in Fig. 9 by means of a plate spring, in the turning of a at the end of the small column 14-u screwed-on disc 36 is inserted and presses against the leaf spring 12a. Via an intermediate disk 38 and an end cap 39 with thread, the whole thing is screwed together, with the cap 39 rests on the inner collar of the disk 36, which is kept so long that the parts in between are not jammed, but rather for the effect of the disc spring Game remains.

Fig. 11 shows the use of the retaining clip 34 »to z. B. to attach a newspaper to the upper edge of the book plate.

One problem with bedside reading devices is where and how to place them and how to fix them so that the not-r maneuverable long holding arm at the attachment point attacking great forces, especially when a heavy book is being held must be intercepted and the whole arrangement has sufficient stability. If the bed frame is not very stable this is often particularly problematic.

FIGS. 12 and 13 show, in an exemplary embodiment, a view from above of the bed with the installation of the stand 8 the column 6 starting from a corner on the left and on the right side of the bed. The corner arrangement allows the same Puss can be used for both sides of the bed, on one side of the bed the legs of the U-shaped stand run parallel to the longitudinal direction of the bed, Fig. 13 and on the other side perpendicular to it, Fig. 12. Above all, however, this corner arrangement allows the the column supporting the G-joint support arm all the way to the head end 48 of the bed Move between the side bed frame 47 and the bedside cabinet and thus no longer interfere.

The arcuate deflection of the joint holding arm extending from the column 6 to the side of the bed around the person lying down and back towards the head so that the book plate with the book is free can be seen in Fig. 12. When not in use

If the long articulated support arm is folded down to small and swiveled aside over the bedside cabinet 49, it is out of the Away and is covered by the bookplate, but the book remains open on the bookplate, ready for reading; the bed reader now has the puncture of a bedside lamp. From lying down you can read on with one hand in seconds the joint holding arm can be swiveled forward again, unfolded and brought into the reading position.

To increase the stability of the stand 8 with the column 6, this is additionally attached to the side bed frame 57 with a clamp 50, Fig. 14.

Fig. 19 shows an example of the embodiment of this Terminal 50. It must be as flat as possible so that the space between the bed and the bedside table can remain small. Two threaded hooks 44 and 45 protrude through a plate 41 with firmly connected sleeves 42 and 43, and enclose the side Bed frame 47. The threaded hooks are tightened with the knurled nut 46 and firmly clasp the edge of the bed 47 · At the A ring or a short pipe part 40 is attached to the plate, the column 6 passing through is fastened with a screw (in Fig. 19 not shown) clamped like an adjusting ring.

Another type of attachment of the articulated support arm Fig. 15 shows column 6 on the bed without using a stand. The column is held here by a three-point attachment namely on the upper and lower edge of the side bed frame 47 each with a clamp 50 and additionally with a clamp 50k on the headboard.

The clamp 50k is in the same way on the bed with two threaded hooks attached as in Fig. 19. Only here is the / l receiving pillar 6 Ring 40 is connected to the plate 41 of the clamp via a spacer A.

The additional drawing Fig. 15a shows the clamp 50k and the fastening on the headboard 48 in plan.

For using the bed reader on a hospital bed made of tubular steel frame a prismatic clamp 54 is provided, which is attached to a vertical part of the bed frame with the steel tube 51 comprises two jaws and pulled together with the screws 54k

will, AtTb. 16, Fig. 18. The pipe section 53 is attached to it with the clamping screw 56. The first part 1a of the joint holding arm is here as a tube part bent at right angles formed, which can be inserted and held in the tubular part 53 of the prismatic clamp. A screw fastening of the bed reader e.g. in the version with a tube part 52 bent at right angles as the first sub-element of the articulated support arm with a plate 55 supporting the pipe section 53 on a vertical surface of the bed or on the wall, Fig. 17 shows

The correct illumination of the reading surface is of particular importance for protecting the eyes when reading; therefore heard the reading lamp becomes a component that cannot be separated from a bed reader and requires careful adjustment. It only a cold light lamp is suitable for this, not only because of the uniform light emission over an extensive area, but also about the heat radiation, which is annoying for many people to the head, which emanates from an ordinary light bulb.

About the annoying hum of the ballast in a fluorescent tube turn off what is in the silence of a bedroom The series reactor and starter are easily perceived as a nuisance housed in a housing 11, which is hung on the wall away from the bed, Fig. 1.

The use of the bed reader is not limited to the bed. With an appropriately adapted attachment to an armchair in the area to the side of the backrest, the articulated arm that stretches around in an arc, the book for the person sitting comfortably and leaning back freely in the most favorable way Reading position held.
