Abstract

The bookstand has a revolver provided in the center of a base plate (14) to rotate a book support plate (6), which is fixed at a carriage (9). An upwardly extending guide rail (7) is connected with the revolver by a hinge (13) to adjust a tilting angle of the support plate. The carriage glides on the guide rail to adjust the height of the support plate and a positioning bolt provided between the rail and the support plate positions the support plate after the rotation of the plate.

Description

technical area

The The invention relates to a rotatable bookstand, which rotates arbitrarily can be.

State of technology

Of the Table usually shows a horizontal table surface. When reading, the book can lie on the table surface or by one hand held by the reader. However, this is very tedious.

Out the patent on 27.03.2002 this inventor (CN 02209361.3) is a bookstand known, which has a complicated structure and not with the Table top can be combined. Therefore, the inventor has one another bookstand developed, which is mounted on the table top. This bookstand is however unrotatable.

Task of invention

Of the Invention is based on the object, a rotatable bookstand create that can be rotated arbitrarily.

These The object is achieved by the bookstand according to the invention, consisting of a base plate, a revolver in the middle of the base plate and a rail that goes over one Joint is connected to the revolver and extends upward, where a slide can slide on the rail, on which a support plate is attached, and being between the rail and the support plate a positioning is provided.

Of the Revolver is over a bearing is rotatably received in the base plate and has a toothed peripheral side, wherein the base plate on the front Side is provided with a spring-loaded positioning pin, which in the toothed peripheral side of the revolver can engage.

Of the Spring-loaded positioning pin has recesses into which a push button can project on the base plate, whereby the spring-loaded positioning pin positioned is.

The Positioning between the rail and the support plate is through a rack in the rail and a spring-loaded latch on the bottom of the support plate is attached, is formed, wherein the spring-loaded pawl can engage the rack and a handle having.

between the rail and the support plate is provided a return element, which is formed by a spring, whose two ends on the rail and the carriage are fixed, the carriage by the spring in the highest Position is held.

The Carrying plate has at the bottom of a raised edge at an angle of about 90 °.

The Carrying plate is with a spring-loaded, magnetic or detachable clamp provided to clamp the worn book.

There the rail over The joint is connected to the revolver, the angle of inclination the rail and thus the support plate are adjusted. Farther can the height the carrying plate by the slide, which slide on the rail can be adjusted. Furthermore, the carrying plate can be replaced by the revolver rotated and positioned by the positioning pin. Therefore be a rotational adjustment, an angle adjustment and a height adjustment of the Carrying plate allows.

Ways to execute the invention

Like from the 1 . 2 and 3 it can be seen, the invention consists of a base plate 14 a revolver 15 in the middle of the base plate 14 and a rail 7 that have a joint 13 with the revolver 15 is connected and extends upward. On the rails 7 can a sled 9 slide on which a support plate 6 is attached.

Like from the 1 and 3 it can be seen, the support plate 6 at random point of the rail 7 be positioned. That's what the rail is for 7 with a rack 10 provided, their teeth on the support plate 6 point. At the bottom of the support plate 6 is a spring-loaded latch 12 provided in the rack 10 can intervene, reducing the support plate 6 is positioned. The spring-loaded latch 12 is on a rotation axis 11 attached, which is provided with a spring on the latch 12 acts. The handle 12 has a handle 2 on. By a pressure on the handle 2 can the latch 12 the rack 10 leave, leaving the support plate 6 can be moved.

Like from the 1 and 2 can be seen, the revolver can 15 to be turned around. That's what the revolver is for 15 rotatable about a bearing in the Grundplat th 14 added. The revolver 15 has a toothed peripheral side 3 on. The base plate 14 is on the front side with a spring-loaded positioning pin 5 and a push button 4 Mistake. The spring-loaded positioning pin 5 has two recesses into which the push button 4 can protrude, causing the spring-loaded positioning pins 5 in the toothed peripheral side 3 of the revolver 15 engage or the toothed peripheral side 3 of the revolver 15 can leave, leaving the revolver 15 can be positioned and released.

When used, the revolver 15 and thus the carrying plate 6 rotated and positioned in the desired angular position. Because the rail 7 over the joint 13 with the revolver 15 is connected, the inclination angle of the rail 7 and thus the carrying plate 6 be adjusted. In addition, the height of the support plate 6 through the sledge 9 who is on the rail 7 can slide, be adjusted. Therefore, a rotational adjustment, an angular adjustment and a height adjustment of the support plate 6 allows.

To adjust the height of the support plate 6 To facilitate, can be between the rail 7 and the sled 9 or the carrying plate 6 be provided a return element. In the present embodiment, a spring 8th provided, whose both ends to the rail 7 and the sled 8th are attached. By the spring 8th becomes the sled 9 held in the highest position. When height adjustment, the support plate must 6 only against the spring force of the spring 8th pulled down and can by the restoring force of the spring 8th be easily positioned at the desired height.

Like from the 1 and 2 it can be seen has the support plate 6 at the bottom a raised edge 1 to hold the worn book. In addition, the support plate 6 be provided with a spring-loaded, magnetic or releasable clamp to clamp the worn book.

by virtue of the above facts, the invention corresponds in its availability, Progressiveness and novelty fully on the requirements for a utility model.

The The above description represents only a preferred embodiment of the invention and should not be used as a definition of boundaries and serve the scope of the invention. All equivalent changes and modifications are included to the scope of this invention.
