PATENT OFFICE.

The present invention relates to a book or other cabinet, its locking panel can be brought into a standing or sitting position and thus serves the dual purpose of one Sitting or standing usable writing desk and bookcase is used.

The attached drawing shows:

Fig. Ι the perspective view of the bookcase in a closed position,

Fig. 2. the corresponding view of the same, with the locking plate lifted and in Brought a standing desk, and

Fig. 3 shows one with the closure plate lowered and in a seated position. brought is;

Fig. 4 is a detailed representation of a side part of the bookcase, and

FIG. 5 shows, in partial view and in section, the guidance of the closure plate in FIG the side parts.

The bookcase α is closed at its front by a closure plate b representing the place of a door. The same hangs in the closed position, carried by pin b ¹ (Fig. 5), in slots forming guide rails c, namely in the laterally widened or. curved Theilen'c ¹ thereof. The rails c are embedded in the side parts α ¹ α ^{2 of} the cabinet. At the lower free end of the plate h, to which a lock can be attached, by means of pins b ' ² levers dd' engage, which are connected to the side parts a ¹ a ^{2 of} the cabinet in that their pins ee ¹ at the other end step through curved guide slots ff ¹ running diagonally from top to bottom. These slots are directed a short distance downwards at their lower end i. When the plate b is closed, the levers ^{dd l} rest with their pin ee ¹ , as can be seen from FIG. 1, in the upper end of the guide slots ff ¹ .

If one wishes to bring the Verschlufsplatte b in lectern position as shown in Fig. 2, so it is only necessary, the same as far as to raise the lower end until the lever dd ^1, which have to follow this movement, BEZW. whose tenons ee ^{l have} entered the downwardly inclined part i of the slots ff ¹ . A falling of the plate is prevented by the engagement of the pins b ^l in the slot parts c ^{1 of} the rails c on the one hand and by the lever dd ¹ attacking the lower end of the plate on the other hand; the pins of these levers are located in the slot parts i of the slots ff ¹ .

In order to bring the closure plate b into the seated position, as shown in FIG. 3, it must be lifted a little upwards and pulled forward. This movement is sufficient to lift the pin b ¹ out of the slot parts c ^{1 of} the rails c and into the path of the straight slots c. The upper part of the closing plate can now, after the lower end has been raised a little at the same time, be lowered unhindered as far as the slots c resp. those intervening in them

Claims (1)

Allow pin b ^l of plate b . The levers dd ¹ respectively. their tenons ee 'follow this movement until they reach the parts i of the slots ff ¹ . The same now hold the plate b in association with the pin b ¹ b ^{2 of the} same and the pin ee ^l unchanged in this position. The return of the locking plate b into its locking position is effected by simply lifting the upper end of the same and by inserting the pin b ^x into the slot parts c ¹ . Patenτ claim: A bookcase, the closure plate (b) of which is used to set up a standing or. Seating desk can be used that it is articulated to the side parts of the cabinet by support levers dd ⁱ , the pins ee ^l are guided in curved slots ff ^{1 of} the cabinet side parts, while the suspension pins b ^{1 of} the plate a slide in lateral guide slots c of the cabinet and the pin (e ^l or b ^A ) is fixed by the slot parts (i and c ¹ ) .
