Abstract

FIELD: hand equipment for obtaining stamp prints on documents. SUBSTANCE: stamping device has outer casing and spring-loaded inner casing enclosed in outer casing for axial displacement within it. Outer and inner casings are interconnected by movable pin carrying stamping plate. Side walls of inner casing are provided with slots for passage of pin which interconnects both casings. Planks with curvilinear slot and two cylindrical pivots are attached to inner surface of each side wall of inner casing for rocking within it. One of pivots serves as axis of rotation of plank and other pivot is inserted into rectilinear slots in stamping plate. Inner casing side walls are made hollow, and rectilinear slots are made in their inner sides. EFFECT: increased efficiency and enhanced reliability in operation. 1 dwg

Description

 The invention relates to the construction of manual stamps designed to obtain prints of seals and stamps on documents, postcards and parcels.

 Known manual stamping device according to US Pat. USA N 4362101, IPC В 41 К 1/30, which has a case with an open lower part limited by a lower edge, with a hole in the upper wall of the case and a stamp impregnated with paint installed in the case itself. In the normal position, the stamp is located above the lower edge of the housing to the upper surface of the stamp, a holder is attached. Relative to the hole, the rod moves vertically, the lower end of which interacts with the holder. During operation, the housing of the device is installed on the marked surface and, after clarifying its position, press the rod.

 The disadvantages of the analogue are the complexity and lack of compactness of the design, as well as the constant openness of the working surface of the stamp, limiting its use and ease of use when traveling.

 The closest analogue to the claimed technical solution is a manual stamping device (certificate N 5382 for a utility model of the Russian Federation, Bulletin PMPO N11, 1997), containing an outer casing in the form of a polyhedron and axially displaced spring-loaded inner casing interconnected therebetween the movable axis on which the stamp plate with the distributor is placed, and on the side walls of the inner case, curved grooves are made for the ends of the axis and a window for accommodating the pallet of the stamp pad. The rotator is made in the form of digital disks with gaskets mounted on an axis in the opening of the stamp plate, with each disk provided with an elastic retainer. The mount of the marking stamp on the stamp body is made in the form of a reverse cone.

 The disadvantages of the prototype device are the presence of complex curved guides that contribute to jamming of the stamp and open grooves on the side walls, which reduce the reliability of the structure, as well as significant noise during operation of the device.

 The objective of the invention is the development of a manual stamping device, which improves the reliability of its operation.

 This problem is solved using the features specified in the claims common to the prototype, such as a manual stamping device comprising an outer casing and axially movable spring-loaded inner casing mounted therein, interconnected by a movable axis on which the stamp is placed, wherein grooves are made on the side walls of the inner case through which an axis passes connecting the bodies and significant distinguishing features such as on the inside of each side wall the tripod housing are fixed with the possibility of swinging the planks with a curved groove having a straight shape in opposite sections and two cylindrical trunnions, one of which serves as the swing axis of the plank, and the other enters into the straight grooves of the stamp plate, and the side walls of the inner case are made hollow, moreover linear grooves are made on their inner sides.

 The above signs characterize the feature of the manual stamping device, which increases the reliability of the structure and reduces the noise level.

 The invention is illustrated by the following drawings. In FIG. 1 shows a longitudinal section of the device, along AA; figure 2 is a top view; figure 3 is a section along BB; figure 4 is a section along BB in the transport state.

 The manual stamping device comprises (Fig. 1) an outer casing 1 with an open lower part, inside of which an inner casing 2 is mounted with axial movement, also with an open lower part. Between the closed parts of the outer 1 and inner 2 cases, an elastic element 3 is installed, tending to push the case 2 out of the case 1. In the front and back walls of the inner case 2 adjacent to its closed part, windows 4 are made through which the pallet 5 with the stamp is installed and fixed cushion 6. The housings 1 and 2 are connected by an axis 7, on which the stamp plate is located 8. On the inner side of the hollow side walls of the inner housing 2, the strips 9 are secured for swinging, provided with pins 10, 11 and a curved groove 12, measuring sections 13 and 14 of a rectilinear shape through which axis 7 passes. Axis 7 also passes through rectilinear grooves 15 on the inner side of the hollow side walls of the inner housing 2. The lower open ends of the hollow side walls of the housing 2 are closed with elastic supports-plugs 16. In this case, the pins 11 are placed in the straight grooves 17 of the stamp plate 8.

 Below is information about the conformity of the features of the claims to the description of the feasibility of the invention.

 The manual stamping device comprises an outer casing 1 and a spring-loaded inner casing 2 mounted therein with axial movement and interconnected by a movable axis 7, on which the stamping plate 8 is placed, and grooves 12 are made on the side walls of the inner casing 2 through which axis 7 passes connecting the case. On the inner side of each side wall of the inner case 2, the strips 9 are fixed with a possibility of swinging with a curved groove 12 having a straight shape in opposite sections 13 and 14 and two cylindrical trunnions 10 and 11, one of which serves as the swing axis of the strap, and the other enters into straight the grooves 17 of the stamp plate 8, and the side walls of the inner case are hollow, and the straight grooves 15 are made on their inner walls.

The device operates as follows. It is necessary to install the device with the open lower part of the inner case 2 above the portion of the document on which to print the stamp and press top down on the outer case 1. At the same time, the case 1 together with the axis 7 and the stamp plate 8 placed on it will begin to move downward, compressing the elastic element 3. Axis 7 moves straight down, because its ends are in straight grooves 15, and makes the bar 9 rotate around the pins 10, because its groove 12 has a curved shape. The strap 9 in the process of its rotation also rotates the pins 11 of the stamp 8 around the axis 7 by 180 ^o . The curved groove 12 of each bar 9 in opposite sections 13 and 14 has a straight shape, which ensures the occupation of the position marking stamp parallel to the document plane, and obtaining an impression, as well as uniform wetting of the marking stamp.
