RU2152313C1 - Stamp back for mounting replaceable printing letters - Google Patents

Abstract

FIELD: office equipment. SUBSTANCE: stamp back is made from flexible material and has dovetail-shaped mounting rollers, closed rectangular or curved restricting frames whose ends define stamp surface. Mounting rollers are formed as wavy lines or closed curved lines, concentric or single, arranged all together or apart, or in other combination. Restricting frames are extending along back perimeter or in some parts of back restricting frames are positioned apart or together. Rectangular mounting rollers are arranged on back in groups of equal or differing length, with groups of mounting rollers being oriented in parallel or perpendicular relation or at an angle one to the other. EFFECT: wider operational capabilities, convenient operation and simplified construction. 3 cl, 3 dwg

Description

 The invention relates to office equipment, and more specifically to equipment for stamps and can be used in office work.

A stamp is known in which a stamping plane in the form of printing marks is formed on a substrate and the substrate is further provided with a window in which there are replaceable printing marks. [1]
The disadvantage of this stamp is the limited use due to the small possibility of making changes to the print, since for making such changes it is necessary to make a practically new substrate.

The closest to the claimed object in its technical essence and the achieved effect is a substrate for mounting interchangeable printing characters made of elastic material with straight and parallel mounting rollers with a dovetail profile made on it. On the specified substrate mounted interchangeable signs with a printing surface, and installation is not difficult. [2]
The disadvantage of this substrate is the limited scope, because for example it does not allow you to mount the text in any desired direction on the plane.

 The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention, and the definition from the list identified analogues of the prototype, as the closest in the totality of the characteristics of the analogue, allowed to identify a set of essential in relation to to the applicant the technical result of the distinguishing features in the claimed object set forth in the claims.

 To verify the conformity of the claimed invention to the requirements of the inventive step, the applicant conducted an additional search for known solutions in order to identify features that match the distinctive features of the prototype of the claimed invention, the results of which show that the claimed invention does not explicitly follow from the prior art defined by the applicant, the influence of the salient features of the claimed invention transformations to achieve a technical result.

 The aim of the invention is to increase ease of use and expansion of functionality.

 The essence of the invention lies in the fact that on the stamp substrate for mounting interchangeable printing signs with mounting rollers having a dovetail profile, additionally, along its perimeter or in separate sections together or separately or in various combinations, closed rectilinear or curvilinear bounding frames are made, the end surface of which forms the stamping plane and the mounting rollers are made in the form of wavy lines or closed curves - ellipses or circles, concentric or single GOVERNMENTAL in various combinations, while rectilinear mounting rollers disposed in different parts of groups of the substrate perpendicularly or at an angle to each other.

 It should be noted that in the explanatory figures below, the dovetail profile is represented with technological rounding of the corners. Accordingly, the shape of the groove formed by two adjacent mounting rollers looks somewhat different from the classic representation of the dovetail lock.

 Thermoplastics such as polyethylene, polypropylene and the like are used as the substrate material. polymers, as well as elastic polymeric materials, such as rubbers, rare copolymers of ethylene with polypropylene, polyurethanes and the like, capable of deforming under the influence of various mechanical stresses, but at the same time possessing high relaxation characteristics.

 The inventive substrate can be made by known methods: for example, by mechanical action with cutting devices (caliper), injection molding, etc.

 If necessary, for the manufacture of the inventive substrate can be used laser engraving with the use of computer monitoring of the technological process, as is, for example, described in British application N 2253112 (publ. In 1992).

 It should be noted that the number, location and shape of the bounding frames made on the stamp substrate, as well as the mounting rollers, are unlimited within reasonable limits, as are the dimensions and the two-dimensional shape of the stamp substrate itself.

 The inventive stamp substrate for mounting interchangeable printing characters is illustrated by drawings.

 In FIG. 1 shows a general view of a substrate in planimetry with partially mounted print marks.

 In FIG. 2 is an enlarged sectional view of a portion of a substrate.

 In FIG. 3 is an enlarged sectional view of a portion of a substrate.

 The inventive stamp substrate for mounting interchangeable printed characters (Fig. 1) is a base 1, on which the restrictive frames 2, 3, 4, etc. are made. between which and inside of which the mounting rollers are parallel and rectilinear 12, curved 13, in the form of concentric circles 14, elliptical 15, located at an angle of 16 or perpendicular to 17. Bounding frames 2, 3, etc. (see Fig. 2 and Fig. 3) form with their end surface 18 and 19 a stamping plane, at the same level with which are mounted signs 20 and 21 with printing surfaces 22 and 23.

 For a better understanding, the claimed technical solution can be illustrated, but not exhausted by the following example of its specific implementation.

 Example 1

 Stamp substrate material FOAM / CUSION, Davies company (Great Britain). The substrate is made by laser engraving. On the substrate plane, various combinations of mounting rollers and bounding frames are performed. Engraving is carried out with a TROTEC-25ER laser. The processing speed is 2.5 cm / s. A rectangular substrate of 5x10 cm in size is obtained on which various signs can be mounted.

 As can be seen from the description, explanatory drawings and diagrams, as well as manufacturing examples, the inventive stamping substrate improves the usability and expands the functionality.
