Description

[Detailed description of the invention] (Field of industrial application) This invention hinges the upper end of the leg to the back of a support plate for books, etc., and adjusts the inclination angle of the support plate by adjusting the opening/closing angle of this leg. lectern, drawing board,
This relates to angle adjustment fittings used for drawing boards, etc.

(Prior art) The present inventor hinged the upper ends of the legs to the back of the support plate,
A lectern for office use that adjusts the angle of inclination of the support plate by adjusting the opening of the legs by touching the upper ends of the legs with the lower ends of angle adjusters that are slidably arranged up and down on the back of the support plate. Developed (Jikko 57-
No. 60359).

(Problem that the invention aims to solve) However, with this lectern, when changing the inclination angle of the support plate, the angle adjuster must be moved up and down by operating the locking pin each time, so it is difficult to handle. This is inconvenient, and if the locking pin is loosened, the legs may open wide and the inclination angle of the support plate may change. Furthermore, this type of product has a complicated structure and has the disadvantage that production costs cannot be reduced.

It is an object of the present invention to overcome these drawbacks and to provide a convenient angle adjustment fitting for a lectern, drawing board, etc., which is even easier to handle.

(Means for Solving the Problems) The present invention consists of an oblong horizontal plate 1 whose one end is fixed to the back of a support plate 3 for books 2, etc., and a vertical plate 5 integrally connected on the extension thereof. This vertical plate 5 is provided with a long guide hole 6 in the longitudinal direction, into which a stop pin 11 of a leg 9 whose upper end is hinged to the back surface of the support plate 3 is fitted, and a lower edge of this guide hole 6 is provided. This is an angle adjustment fitting for a lectern or the like in which recesses 7 for locking stop pins 11 are formed at intervals, and one end of the horizontal plate 1 is fixed to the lower part of the back of the support plate 3 using screws 4 or the like. A stop pin 11 protruding from the side surface of the leg 9 is fitted into the guide hole 6 of the vertical plate 5 to form a lectern or the like.

(Embodiment) Next, an embodiment of the angle adjustment fitting for a lectern or the like according to the present invention will be explained based on the drawings. It is a horizontally long metal horizontal plate to be fixed, and 5 is a horizontally long vertical plate made of the same material and integrally connected from one side of the other end of the horizontal plate 1 on an extension thereof. An elongated guide hole 6 is formed in the vertical plate 5 over almost the entire length in the longitudinal direction, and a plurality of recesses 7 are formed at intervals on the lower edge of the guide hole 6. Further, a finger hook 8 for operation is curved at the upper edge of the tip of the vertical plate 5.

Reference numeral 9 denotes a leg whose upper end is hinged to the back surface of the support plate 3 with a hinge 10, and a stop pin 11 protruding from the side surface of the leg 9 is movably fitted into the guide hole 6. In addition, the reference numeral 12 is a support rod that is attached to the front surface of the support plate 3 so as to be able to rise and fall and supports the lower end of the book 2, etc., and the reference numeral 13 is a metal fitting for holding down the book 2, etc., with one end fixed to the upper corner of the front surface of the support plate 3. It is.

Since one embodiment of the present invention has the above-mentioned configuration, one end of the horizontal plate 1 is fixed to the lower part of the back surface of the support plate 3 with screws 4, and the vertical plate 5 is fixed as shown in FIGS. When fitting and installing the stop pin 11 of the leg 9 into the guide hole 6, the stop pin 11 moves within the guide hole 6 due to rearward rotation of the leg 9, and the horizontal plate 1 curves accordingly. When it reaches the recess 7, the stop pin 11 is fitted into the recess 7 by the spring action of the horizontal plate 1, the rotation of the leg 9 is stopped, and the support plate 3 is stabilized in a slightly inclined state. Further press the finger hook 8 to release the stop pin 11.
When the leg 9 is removed from the recess 7 and the leg 9 is rotated backward, the stop pin 11 is fitted into the next recess 7, the rotation of the leg 9 is stopped, and the support plate 3 is stabilized in a further tilted state.

Next, if the leg 9 is rotated forward while pressing the finger hook 8, the leg 9 will overlap the back of the support plate 3, and the real product will also overlap the back of the support plate 3 due to the spring action of the horizontal plate 1, and the leg 9 will overlap the back of the support plate 3. This prevents it from rotating backwards.

Incidentally, although the above embodiment shows the case where the device is used as a lectern, it goes without saying that it can also be used as a drawing board, a drawing board, etc. Further, although the horizontal plate and the vertical plate are made of metal, they can also be made of plastic or the like.

(Effects) As detailed above, the angle adjustment fittings for lecterns, etc. according to the present invention can be easily manufactured by punching and bending a single metal plate, and can be easily manufactured by punching and bending a single metal plate. Since it is easy to install, the production cost of lecterns and the like can be greatly reduced.

Moreover, when using the angle adjustment fitting according to the present invention, the legs can be opened and closed easily, and when the legs are opened and the stop pin and the recess fit together, the spring action of the horizontal plate ensures the above-mentioned fitting. Unless the vertical plate is manually pressed, it will not come off and the inclination angle of the support plate will not change, so you can read books with peace of mind. Furthermore, when the legs are folded onto the support plate, the springs on the horizontal plate prevent the legs from moving blindly and the legs are held on the back of the support plate without swinging, making it extremely convenient to handle.
