BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This is an application pursuant to 35 U.S.C. 371 of International Application PCT/AT95/00235 filed 29 Nov. 1995.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a stamping device with top inking, a preferably metallic receiving frame for a stamping insert guided in side portions of the receiving frame and reversible by means of a reversing mechanism between an ink receiving position in engagement with a ink pad and a printing position by a U-shaped preferably metallic actuator bow connected to the stamping bow and manually moveable against the bias of a spring relative to the receiving frame.
2. The Prior Art
Stamps of this type, as known, for instance, from German Offenlegungsschrift 2,020,162, are used in large numbers, and because of the requirement of longevity even under rough treatment they have hitherto been made almost entirely of metal components, with the bias spring of the actuator element being guided in a central hollow cylinder or the like extending between the upper surface of the housing and the metal bow so that the space above the upper surface of the housing cannot be used for other purposes, such as, more particularly, providing a replica of the entire image of the stamp. Moreover, the fabrication of all components from metal is exceedingly expensive and it is disadvantageous because of the scarce possibility of reusing the components making up a stamp which is no longer useable.
OBJECTS OF THE INVENTION
The invention aims at providing a stamping device of the type referred to supra which while maintaining a robust construction is, on the one hand, user-friendly relative to devices known heretofore and which, on the other hand, makes possible a more cost-efficient fabrication and reuse of the stamp. At the same time, the stamp is to ensure an improved stamped image.
SUMMARY OF THE INVENTION
The stamping device in accordance with the invention is characterized by a frame for receiving the stamping insert being mounted in a substantially parallelepiped outer housing made of plastic, in the two side portions of which there are provided receptacles for the side portions of the receiving frame and for one pressure spring each or for the arms of the actuator bow, and by the actuator bow being inserted in an external frame made of plastic the lateral portions of which extend into the two pressure spring receptacles.
In accordance with a preferred embodiment of the invention, the frame for receiving the stamping insert and the reversing mechanism forms an upwardly facing U-shaped opening, is integrally formed and is provided with a support frame portion embracing an opening through which the stamping insert may be moved.
In accordance with a further characteristic of the invention the transverse braces connecting the support frame portion are covered by rubber-like plastic staves supporting pins penetrating through openings in the transverse braces in the direction of their lower side. In this manner, slip proof placing of the stamping device and flawless centering of the printed image are ensured.
As an element of the invention, the lateral components of the external plastic housing are connected by upper and lower transverse connections and are provided with cavities for receiving the pressure springs as well as the arms of the actuator bow.
The upper transverse connection of the lateral components for practical purposes forms a coverable receptacle for receiving a replica of sample the stamp image.
In the stamping device in accordance with the invention the actuator bow of the actuator element and the U-shaped plastic frame embracing it may be connected by a pin which lockingly engages an actuator knob extending from the actuator frame.
