RU206527U1 - Hole punch for stitching holes in a stack of sheets of paper - Google Patents

Abstract

The utility model relates to punching devices and is intended for punching holes on a document. A hole punch for piercing holes in a stack of paper sheets contains a base with two brackets fixed and located along the base parallel to each other at a distance, two spring-loaded rod perforating elements with sharpening at the working end for punching holes of the same diameter installed in the brackets, and a pressure lever, hinged on the brackets and installed with the possibility of interaction with the perforating elements to ensure their movement up and down through the guide holes in the base. In the pressure lever there are two holes on different sides on the same line, into which covers are installed for fastening the laser in an interference fit with the possibility of indicating the evenness of drawing holes on the paper. The result is an even hole pattern. 1 ill.

Description

Technology area

The utility model refers to punching devices and is intended for punching holes on a document consisting of a set of separate sheets, in the process of preparing it for firmware into a single document with the possibility of aligning the holes using lasers, for subsequent placement in a folder in financial, economic, legal, educational and other areas of activity.

State of the art

Known hole punch containing: base, including at least one U-shaped bracket mounted on the base, while each of these U-shaped brackets includes a front end, a rear end, two protrusions formed on the bracket through the gap, at least one cutting device slidably mounted through a guide hole in at least one bracket, one articulated joint corresponding to at least one bracket on the base and connected to at least one bracket on the base, to at least one cutting device and to the top cover and an intermediate segment attached to at least one corresponding cutting device (patent RU 66266, IPC B26F 1/36, published: 09/10/2007 bull. No. 25).

The disadvantage of the known device is the unnecessary complexity of regulating the same distance of the holes in the stack of sheets of paper.

Known hole puncher for firmware, containing a base with two brackets mounted motionless and located along the base parallel to each other at a distance, two spring-loaded rod perforating elements with sharpening at the working end, installed in the brackets, and a pressure lever, hinged on the brackets and installed with the possibility interaction with the perforating elements to ensure their movement up and down through the guide holes in the base, is equipped with a bracket and a spring-loaded rod perforating element installed on it with a sharpening at the working end to a certain diameter (patent RU 103510, IPC B26F 1/00, published: 20.04. 2011 Bulletin No. 11).

The disadvantage of this device is the unnecessary complexity of regulating the same distance of holes in the stack of sheets of paper.

The objective of the present utility model is to provide a hole punch that reduces labor costs and enables the user to easily adjust the same hole spacing in a stack of paper sheets.

Disclosure of a utility model

The technical result of the utility model is the creation of a hole punch for the firmware, indicating the application of holes.

The technical result is achieved in the device a hole punch for piercing holes in a stack of sheets of paper, containing a base with two brackets mounted fixedly and located along the base parallel to each other at a distance, two spring-loaded rod perforating elements with sharpening at the working end for punching holes of the same diameter installed in brackets, and a pressure lever, hinged on the brackets and installed with the ability to interact with the perforating elements to ensure their movement up and down through the guide holes in the base, and in the pressure lever two holes are made, from different sides on the same line, into which the covers are installed in the hole for fastening the laser in an interference fit with the ability to indicate the evenness of drawing holes on the paper.

The hallmark is:

in the pressure lever, two holes are made, from different sides on the same line, into which the covers are installed in the hole for fastening the laser in an interference fit with the possibility of indicating the evenness of applying the holes on the paper, this is the ability to track the evenness of applying the holes on the stack of paper sheets and indicating the application of the holes.

Comparison of the proposed solution with the analogue and the prototype did not allow us to identify in them the features that distinguish the proposed solution, which allows us to conclude that the criterion of "novelty" is met.

Brief description of the figure

FIG. depicts an isometric view of a hole punch for firmware, including: 1 - pressure lever; 2 - spring; 3 - rod perforating element with sharpening at the working end; 4 - the base of the hole punch; 5 - covers in the hole for fastening the laser in an interference fit.

Implementation of the utility model

The device is manufactured using the following technology. The pressure lever of the laser hole punch is manufactured by injection molding into a custom mold.

The device operates as follows. The lasers are installed in the cases 5 fixed in the holes in the tightness up to the stop, made in the pressure lever 1. The lasers indicate the line of the holes. By hand pressure on the pressure lever 1 rod perforating elements with sharpening at the working end 3 make holes on the stack of sheets of paper and the hole punch, with the help of springs 2, returns to its original state.
