Description
Die vorliegende Erfindung hat eine Vorrichtung zum Aufspannen photographischer Papiere o. dgl. beliebiger Größe auf einem Brett o. dgl. zum Gegenstand. Das Wesen der Erfindung besteht darin, daß an den vier Ecken eines verhältnismäßig großen Brettes Spannfüße drehbar vorgesehen sind, die aus mehreren Gelenken bestehen und gegen die Brettwand federn. Durch die gelenkige Ausgestaltung und die drehbare Anordnung der Füße ist es möglich, jede beliebige Blattgröße ohne Mühe auf dem Brett festzuhalten, so daß das lästige Befestigen mittels Reißstifte überflüssig wird.The present invention has apparatus for mounting photographic printing Papers or the like of any size on a board or the like on the subject. The essence the invention is that at the four corners of a relatively large board Clamping feet are rotatably provided, which consist of several joints and against the Spring board wall. Due to the articulated design and the rotatable arrangement of the Feet it is possible to hold any size of sheet on the board without effort, so that the annoying fastening with drawing pins becomes superfluous.
Die Füße bestehen zweckmäßig aus drei oder mehr miteinander drehbar verbundenen Teilen, von denen der eine Endteil beispielsweise mittels Holzschraube befestigt wird, während der andere Endteil mit einer Abbiegung versehen ist, derart, daß diese Abbiegung auf das Brett drückt, während die anderen Teile das Brett nicht berühren.The feet expediently consist of three or more rotatably connected to one another Parts of which one end part is fastened, for example by means of a wood screw, while the other end part is provided with a bend such that this bend presses on the board while the other parts are not touching the board.
Statt der Federung des freien Teiles in sich könnte dieser auch mit einem federnden Druckstift versehen sein.Instead of the suspension of the free part in itself, this could also be done with a resilient pressure pin be provided.
In der beiliegenden Zeichnung ist eine Ausführungsfonn
des Erfindungsgegenstandes beispielsweise dargestellt, und zwar zeigt:
Fig. ι ein Brett mit an jeder Ecke befestigten! Spannfuß,In the accompanying drawing, an embodiment of the subject matter of the invention is shown as an example, namely shows:
Fig. Ι a board with attached to each corner! Clamping foot,
Fig. 2 einen Spannfuß in Aufsicht, und Fig. 3 denselben in Seitenansicht.2 shows a top view of a clamping foot, and FIG. 3 shows the same in side view.
Bei dem dargestellten Ausführungsbeispiel bezeichnet ι ein Brett beliebiger Größe,, wie es zum Aufspannen photographischer Papiere zwecks Vergrößerung in der Dunkelkammer benutzt wird. An diesem Brett sind die Spann-füße 2, 3, 4, 5 mittels der Holzschrauben 6 oder auch in anderer zweckentsprechender Weise befestigt. Jeder der Füße 2,3, 4, 5 besteht aus dem mittels Schraube zu befestigenden Teil 2', einem mittleren Teil 2", 3", 4", 5" und einem Endstück 2'", 3'", 4"', 5'". Die drei Teile sind gelenkig miteinander verbunden. Das Endstück 2'", 3'", 4'", 5"' ist zweckmäßig abgebogen, und zwar εο, daß das Ende 2a, $a, 4?, 5a auf das Brett drückt.In the illustrated embodiment, ι denotes a board of any size, as it is used to stretch photographic paper for the purpose of enlargement in the darkroom. The clamping feet 2, 3, 4, 5 are fastened to this board by means of the wood screws 6 or in another appropriate manner. Each of the feet 2, 3, 4, 5 consists of the part 2 'to be fastened by means of a screw, a middle part 2 ", 3", 4 ", 5" and an end piece 2'", 3 '", 4 "', 5 '". The three parts are articulated together. The end piece 2 '", 3'", 4 '", 5"' is appropriately bent, namely εο that the end 2 a , $ a , 4 ?, 5 a presses on the board.
