SU1335486A1 - Clamp for sheets of books - Google Patents

Abstract

The invention relates to office supplies, namely, clamps holding books (magazines, notebooks) in the open position. The aim of the invention is to improve the usability. The clamp contains the bottom 1 pivotally connected by the axis 3 and the upper clamping element 2 and the spring 4 on the axis 3. The lower clamping element 1 has a pointed flat head protruding beyond the upper element 2, i.e. beyond the clamping part of the clamp . In addition, the upper element 2 has wings (stops), i.e. T-shaped. The clamp allows the magazines and books to be held in the open position, for which the lower clamping element 1 is inserted between their pages, and the upper element 2 acts by wing-stops on these pages and holds them by the force of the spring 4 placed on the axis 3. 4 Il.

Description

The invention relates to office equipment, in particular to stationery accessories such as clips for book sheets, in order to hold it in the open position, similarly to magazines and notebooks.

The aim of the invention is to improve the usability.

FIG. 1 shows a clip attached to a book, a general view (setting with a cliff and a bend line of a book); in fig. 2 - the same, side view (without furnishing); in fig. 3 - lower base; in fig. 4 - the same, bottom view.

The clamp comprises a lower element 1 and an upper element 2 movably connected by an axis 3, and a torsion spring 4 (the ends of the spring are shown) located on the axis 3 between the lower element 1 and the upper element 2.

The clamp works as follows.

The book 5 is opened on the desired page, the pointed flat head of the lower element 1 is inserted into the gap between the sheets, capturing an unspecified number of sheets sufficient to secure the clamp, moving closer to the bend line of the book 5 so that the T-wing of the upper element 2 crosses the line bend the book 5, pressing the ends of the bottom 1 and top 2 elements opposite the head of the bottom element 1, open the clamp and feed it slightly forward and close the clamp with the help of the top element 2, compressing a certain amount of sheet on both sides, a clamp is secured instantly, and wings (stops) located camping on both sides of the fold line 5 of the book, hold both

parts from closing.

At the end of the work, pressing the ends of the lower 1 and upper 2 bases, the clip is removed from the book.

The presence of wings (stops) at the top

the clip element 2 allows it to be used to hold the sheets of the book 5 in the open position of the book, ensuring the open position of the book on the desired pages.

In addition, the presence of a protruding pointed trapezoidal flat head at the lower element 1 allows the protruding pointed flat head to be quickly inserted into the gap between the sheets of the open book 5 without damaging the sheets, and also use the same head to cut the sheets of the book 5.

Claims (1)

Invention Formula A clip for book sheets containing pivotally connected spring-loaded flat clamping elements, characterized in that, in order to increase usability, one of the clamping elements is T-shaped and the other is trapezoidal with protruding beyond the limits of the first clamping element sharp edges. 2 Phi2.
