PROTECTIVE PIECE FOR THE CENTER HOLE OF VINYL RECORDS

[0001] .

[0002] DESCRIPTION OBJECT OF THE INVENTION

[0003] The invention to which this utility model specification refers, as its title indicates, refers to a protective piece for the center hole of vinyl records, as an element that is placed over the central part of the vinyl record to maintain the exact measurement of its center hole despite the intensity of use. FIELD OF INVENTION

[0004] The present invention falls within the field of designing adaptable parts for handling hard plastics and can be particularly applied in the industrial field of manufacturing. BACKGROUND OF THE INVENTION.

[0005] The inventor has not found any noteworthy precedent that could be considered a direct precedent, which could represent any barrier to granting the proposed utility model.

[0006] The inventor declares that he is unaware of any protective pieces for vinyl that offer the novel features and functionalities of the proposed invention. DESCRIPTION OF THE INVENTION

[0007] The invention referred to in this document focuses on protecting the central hole of vinyl records to prevent problems caused by wear and tear from continued use.

[0008] For this purpose, a piece in the form of adhesive sheets has been provided, simple and easy to use, which corrects the tendency of the disc to wear axially and sometimes not symmetrically.

[0009] This adhesive sheet is made of a wear-resistant material, always framed within the central information circle of the vinyl records, and has a circular hole in its center that fits perfectly on the axis of the record player.

[0010] The protective piece can have different perimeter profiles, but always sufficiently balanced so as not to distort the rotation speed of the vinyl record.

[0011] The protective piece has a free advertising surface on its upper side and an adhesive surface on its lower side that adheres to the upper side of the vinyl record. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] To complement the description being made and in order to help a better understanding of the characteristics of the invention, five sheets of drawings are attached to this descriptive report as an integral part thereof, in which identical elements are indicated with identical references and where, for illustrative and non-limiting purposes, the following has been represented: FIGURE NO. 1.-

[0028] The invention referred to in this document focuses on protecting the central hole of vinyl records to avoid problems caused by wear and tear.

[0029] For this purpose, a piece in the form of adhesive sheets has been provided, simple and easy to use, which corrects the tendency of the disc to wear axially and sometimes not symmetrically.

[0030] In a preferred embodiment, the designed protective piece (2) consists of a sheet of wear-resistant material, always framed within a circle with a diameter (9) of 50 mm, with a maximum of 100 mm, which is the maximum diameter of the central circular information label they bear, and a thickness (10) between 0.2 mm and a maximum of 0.7 mm. These dimensions are suitable so that when the vinyl record rotates on the turntable platter, the moment of inertia does not distort the speed of the vinyl record (3). It has a circular hole in its center with a diameter of 7.3 mm that fits perfectly on the spindle of the standard 7.2 mm turntable.

[0031] In the case of a turntable spindle with a diameter larger or smaller than the standard, the protective piece (2) will always have a diameter 0.1 mm larger than said diameter.

[0032] The protective piece (2) can have different perimeter profiles (7), but must always be sufficiently balanced so as not to distort the rotation speed of the vinyl (3). Depending on the profile (7), it may have gaps without material so that the sum of the missing material in the gaps (8) and the material defined by the profile (7) helps to balance the assembly and achieve the necessary equilibrium so that the protective piece (2) does not distort the rotation speed of the vinyl (3).

[0033] The protective piece (2) has on its upper face a free advertising surface (6) and on its lower face an adhesive surface (5) that adheres to the upper face of the vinyl record (3).

[0034] Having sufficiently described the nature of the invention, as well as the manner of carrying it out, it should be noted that the provisions indicated above and represented in the accompanying drawings are subject to detailed modifications as long as they do not alter their fundamental principles, established in the preceding paragraphs and summarized in the following claims.

Claims

Protective piece for the center hole of vinyl records characterized in that the protective piece (2) is made of a sheet of wear-resistant material, always framed within a circle with a maximum diameter (9) of 100 mm and a thickness (10) between 0.2 / 0.7 mm, which has in its center a circular hole (4) of 7.3 mm in diameter to fit perfectly on the axis of the turntable (1) of standard size 7.2 mm, and where said protective piece (2) adopts different perimeter profiles (7), and depending on the profile (7), it may have windows (8) without material, and having on its upper face a free advertising surface (6) and on its lower part an adhesive surface (5) that adheres to the upper face of the vinyl record (3) Protective piece for the central hole of vinyl records according to claim 1 and characterized in that for a turntable shaft (1) of more or less diameter than the standard, the protective piece (2) will always have a diameter 0.1 mm greater than said diameter. Protective piece for the central hole of vinyl records according to claim 1 and characterized in that the protective piece (2) can adopt different perimeter profiles (7), but always sufficiently balanced so as not to distort the rotation speed of the vinyl (3). Protective piece for the central hole of vinyl records according to claim 1 and characterized in that, depending on the profile (7), it has windows (8) without material so that the sum of the lack of material of the windows (8) with that of the material defined by the profile (7), balance the assembly so that the protective piece (2) does not distort the rotation speed of the vinyl (3).
