Description

FIELD OF THE INVENTION

The utility model relates to stationery, or rather, to devices that allow you to fix the spread of the printed product (for example, passports) in the clear.

BACKGROUND

A device is known for fixing the turn of a stitched printed product in an open form containing a plate (which in the working position is located behind the stitched product) and the protrusions connected to it located at the ends of the plate, while the turns of the product in the working position are located in the space between the said plate and the protrusions ( Japan Patent No. JP 3115676 U).

A disadvantage of the known device is its bulkiness (as shown in the figures in the patent, the dimensions of the device correspond to the dimensions of the printing product approximately as 1: 2), and, as a consequence, the high material consumption. Such dimensions will not allow the user to carry the device with them in a purse or in the cover for a passport. In addition, the size of the protrusions of the known product is so large, and their location (approximately in the center of the pages of the printing product) is so unfortunate that they obscure a rather significant area of the text.

DISCLOSURE OF USEFUL MODEL

The objective of this utility model is to create a compact device for fixing the turn of a stitched printed product in an open form.

The technical result of the utility model is that the proposed device for fixing the turn of the stitched printed product in open form is more compact and to a lesser extent prevents the reading of text from the pages of the printed product.

The specified technical result is achieved due to the fact that the device for fixing the turn of the stitched printed product in open form, contains:

the jumper and the protrusions connected longitudinally elongated in one direction; the central protrusion and the first and second lateral protrusions located at a predetermined distance from it on the sides, together forming a figure with outlines of the letter W in plan,

wherein said lateral protrusions are located essentially in the same plane,

said central protrusion at least partially located at a distance from the plane in which said lateral protrusions are located at a predetermined distance from it.

As will be understood by a person skilled in the art, compactness is ensured mainly due to the fact that in the proposed construction, the rotation is secured with a sufficiently close arrangement of the protrusions to the spine, while the protrusions are located on the free field of the spread and do not block the text.

Further, the above described device, characterized in general categories, is illustrated by the example of some particularly preferred forms of execution, providing additional benefits.

The jumper and the central protrusion, in one of the preferred forms of execution of the above device, are located in the same plane, and the side protrusions, at least partially in the coplanar plane.

Said jumper, in one of the preferred embodiments of the device described above, is located in the same plane with said lateral protrusions.

The location of the planes of the central and lateral protrusions at a distance from each other is necessary to avoid excessive force when installing the product in the working position and to prevent the formation of traces (permanent deformation of the paper, wrinkling) on the printing product. The distance between the planes, it is desirable to choose approximately equal to 0.4-1.2 thickness of the printing product.

Said jumper, central and / or side protrusions, in one of the preferred forms of execution of the above device, are made in one piece. With this form of execution, the least number of stages is required in order to make the product by polymer casting.

Said jumper and / or said protrusions, in one of the preferred embodiments of the above-described device, have a plate shape. The lamellar shape allows to provide the largest contact area of the protrusions with sheets of paper and prevents them from slipping out of the gap between the central and side protrusions.

Said jumper and / or said protrusions, in one preferred embodiment of the apparatus described above, have a circular cross section.

The distance between the said central protrusion and the lateral protrusions in the plan, in one of the preferred forms of execution of the above device, is from 2 to 12 mm, preferably from 7 to 9 mm.

The distance between the at least part of the central protrusion and the plane in which the lateral protrusions are located, in one preferred embodiment of the above device, is from 1 to 8 mm, preferably from 1.5 to 2.5 mm.

The width (from one to the other side protrusion) of the device, in one of its preferred forms of implementation, is 25-55 mm, preferably 41-43 mm, and the length (from the jumper to the end of the protrusions) is 30-75 mm, preferably 46 -48 mm. With the indicated dimensions, the strength of the product will be sufficient to withstand the spontaneous closing of the spread of a printing product, such as a passport.

The gap between the central protrusion and the side jumpers, in one of the preferred embodiments of the above-described device, is at least partially tapering in the direction from the free ends of the protrusions to the jumper. This embodiment allows you to adjust the compression density of the pages of the printing product.

In one of the preferred forms of execution of the above device, it can be made of plastic, preferably transparent plastic.

In one of the preferred forms of execution of the above device, it is made of metal.

The design and use of the device is clearly illustrated by figure 1 on the example of one of the specific embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 (A) and (B) are photographs of the proposed device in working condition - the device captures the spread of the passport.

View "A" - a front turn, a jumper and side protrusions are visible.

View "B" - a reversal at the back, a jumper and a central ledge are visible.

IMPLEMENTATION OF A USEFUL MODEL

As shown in FIG. 1A and B, the proposed device for fixing the turn of the stitched printed product in open form, contains a jumper and protrusions longitudinally elongated in one direction: a central protrusion and first and second side protrusions located at a predetermined distance from it on the sides, together forming a figure with the outlines of the letter Ш in the plan. Said lateral protrusions are located essentially in the same plane. Said central protrusion is at least partially located at a distance from the plane in which said lateral protrusions are located at a predetermined distance from it. The device is preferably made in one piece of plastic. The gap between the central protrusion and the side jumpers is at least partially tapering in the direction from the free ends of the protrusions to the jumper, which allows you to adjust the compression force of the pages of the page depending on how far they are retracted relative to the jumper.

To fix the spread of a printing product, for example, a passport, part of the turn (left and right relative to the spine) is threaded into the gaps between the left and right side protrusions and the central protrusion, respectively, while the central protrusion abuts the spine of the printing product from the back, and the side protrusions devices prevent closing of the left and right parts of the printing product. The side protrusions are removed a short distance from the central protrusion and in the working position are located near the root of the passport without obscuring the text.
