Abstract

Pillow, which being constituted by an indeterminate number of spacer fabric elements (2a, 2b, 2c, 2d, 2e, 2f), arranged concentrically to each other, and wherein each element of spacer fabric is joined at its ends to form a substantially oval tubular body, is characterized in that the connection of each of the elements of spacer tissue (2a, 2b, 2c, 2d, 2e, 2f) is made by ultrasonic welding (3a, 3b, 3c, 3d), 3e, 3f), respectively.

Description

Pillow.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a pillow, which is materialized based on tissue elements spacer, also called three-dimensional tissue, providing a high degree of ventilation and comfort with the maximum hygiene

The object of the invention is to simplify the union of the spacer tissue elements constituting the pillow and get better performance as well as greater durability of the same with respect to the conventional ones and that they also use spacer fabric elements, but with different way of joining these.

The field of application corresponds to all types resting body for people, from a mattress to a simple cushion, going through what is a pillow as such, including seats of armchairs, sofas, mats, etc., and even carpets

Background of the invention

As is known, there are different types of pillows, so that depending on the material used in each  case, as well as the thickness, weight and even cover that is used, they will contribute some or other properties of use.

Specifically, there are pillows that they are based on what is known as spacer tissue, which provides a high degree of ventilation, optimal hygiene and high comfort, in addition to allowing easy washing without the need of separating the cover of the constitutive core of the pillow itself. In addition, drying is fast since the water is not adhered to the core, by virtue of precisely nature and characteristics of this, since this type of spacer fabric is formed by two layers separated and joined together by filaments, fibers or threads.

In that sense, the pillow can be cited described in the invention patent W02006 / 1222614, whose core or padding consists of a plurality of tissue elements spacer, with certain treatment processes to get a permanent deformation, and arranged concentrically with each other and joined in each case by adhesive, closing the corresponding envelope in the form of a perimeter finish with a sewn tape or bias, which can lead to its effectiveness may be diminished after several wash cycles.

Said fixing system presents the inconvenience of having to have non-fabric materials spacer, so that over time and after use, it they lose their properties and consequent destructuring of their own pillow core.

On the other hand, the productive process of the pillow as a whole is complex, for having to use Several different materials.

Likewise, it is noteworthy to mention that the use of adherents, regardless of the degree of Solvents containing, may result in a limitation of use of the product (pillow), because there may be users who have allergic reactions upon contact with them.

Description of the invention

The pillow of the invention is based on described in the previous section, that is constituted based on a plurality of spacer fabric elements, arranged concentrically with each other, but with the special particularity of that each element of spacer tissue joins at its ends by ultrasonic welding, forming an element of oval section

The pillow, as is evident, will be constituted through the framework that determines a plurality of elements concentric, each of which closes and joins by its ends with ultrasonic welding, as stated with anteriority.

Another novelty feature of the pillow the invention resides in that the welding of the different concentric elements are alternated; that is, welding of an element at one end and the welding of the adjacent element at the opposite end, determining an alternation of welds to achieve uniformity throughout the section of the fabric that makes up the pillow itself.

Based on the new way of joining the ends of the elements that make up the pillow, that is to say spacer fabric elements, avoid having to use adhesives, which means better performance after several cycles of use (interaction with the user's sweat), also achieving a better behavior in the processes washing

Finally, say that the cover for the core or filling of the pillow of the invention will also be closed by ultrasonic fusion, avoiding sewing and other means conventional perimeter closure; that is, without need, for of course, using materials other than spacer fabrics, ultimately providing a better final finish of the product.

Brief description of the drawings

To complement the description that is going to perform and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive, of a sheet of drawings that allows understanding with more easily innovations and advantages of the object pillow of the invention.

The figure represented on that sheet of drawings, shows a cross-sectional view of the pillow of the invention, showing different concentric elements, each of which joined by its ends and where the welds remain alternated

Description of the preferred embodiment

As you can see in the commented figure, the pillow 1 of the invention comprises a core constituted by  the arrangement of a series of concentric elements 2a, 2b, 2c, 2d, 2e and 2f, the number of elements may be greater or lesser concentric, so that in each case the elements have a oval cross section and are closed at their ends by welding 3a, 3b, 3c, 3d, 3e and 3f, with the particularity that these welds are alternated, that is that the welding of an element is at one end while the welding of the adjacent element is at the opposite end, being able to see in this sense the welding 3a of the element 2a more external, is at the opposite end of welding 3b corresponding to element 2b immediately adjacent to the previous one, and so on, so that that alternative provision of the welds give rise to a uniformity in the thickness of the core corresponding to the pillow, as shown clearly in the figure.

Evidently that core or padding 1 it will be complemented with the corresponding cover, whose closure is will also establish by ultrasonic welding, avoiding with it, on the one hand, use adhesives, and on the other side avoid sewing or other closure elements, with greater durability in the time of use of the pillow itself, and without see the intrinsic properties of the tissue itself diminished spacer that constitutes each of the forming elements of the core of the pillow itself 1.

Claims (2)

1. Pillow, which being constituted by an indeterminate number of spacer tissue elements (2a, 2b, 2c, 2d, 2e, 2f), arranged concentrically with each other, and where each spacer tissue element is joined at its ends to form a substantially oval tubular body is characterized in that the union between each of the spacer tissue elements (2a, 2b, 2c, 2d, 2e, 2f), is carried out by ultrasonic welding (3a, 3b, 3c, 3d , 3e, 3f), respectively. 2. Pillow according to claim 1, characterized in that the welds (3a, 3b, 3c, 3d, 3e, 3f) of the different spacer fabric elements are arranged alternately, determining that the welding of an element is at the end opposite to the welding of the adjoining element, determining that the corresponding core of the pillow (1) has a uniformity throughout the entire section of the core itself.
