Abstract

Leg for rest equipment, which is provided for its preferred application in bases and support bases for mattresses, is characterized in that it is constituted by an extruded cylindrical profile on whose upper end incorporates a metal insert with an external threaded section for its fixation to the corresponding base or base, while its lower end is capable of incorporating a support cap or a displacement wheel, it being provided that the fundamental cylindrical profile can be constituted by coextrusion with a core of a recyclable or second quality material, which optionally includes a foaming agent in its interior.

Description

Leg for rest equipment.

Object of the invention

The present invention relates to a leg for rest equipment, specifically for application in bases and mattress bases, and in any case set the support medium between the base or bed base and the floor.

The object of the invention is to reduce costs of manufacturing the legs for the elements above referrals (bases and bed bases), as well as obtain a simplification structural of the leg itself, with the consequent advantages of savings on the final product and its corresponding handling and mounting.

Background of the invention

The rest teams, such as the bases and / or canapés and bed bases, incorporate legs for support on the ground, legs that can be of very different constitution and of varied materials, although these are usually made of wood or metal

When the legs are made of wood, it it requires a machining and a coating finish, while when the legs are made of metal, in the process of construction also involves welding and painting of different parts, so together with the amount of measurements and colors possible, manufacturing is expensive.

Description of the invention

The recommended leg has been designed to solve the problem described above, based on a Simple solution but very effective.

More specifically, the leg of the invention is based on an extrusion manufacturing process, whose technology allows to obtain an extruded profile with the shape and color definitive, which simplifies the construction process or Mounting to the single placement of a threaded insert, to join it to the corresponding base or box spring, being able to incorporate in its bottom end any type of support element, from a simple counting to improve the adhesion with the ground, until classic wheels that allow the movement of the base or box spring in which it is applied, all so that the placement of the lower quarry or wheels and the extruded leg will be made by trimming / threading of different types of inserts.

The base material chosen to obtain the leg will preferably be PVC, due to its good properties mechanical and high impact resistance, although it is possible use any other appropriate thermoplastic material.

In addition, in the manufacture of the extruded profile by which the leg itself is constituted, you can also use the technology variant called co-extrusion, in order to reduce the cost of product being able to use recycled or second quality material, in the soul of the profile, this technology that allows besides the savings for the use of savings for the use of the material, the possibility of using a virgin material with different colors and textures in the outside.

In addition to the technology of co-extrusion and in order to reduce the cost of final product, it is considered advantageous to use two of the advantages fundamental that brings the use of extrusion technology and co-extrusion, which correspond to the use of agents foaming materials and longitudinal channels that allow to obtain a profile with less weight.

Obviously, the insert that mounts on the upper end of the leg may be any of the commonly used in this sector of the technique, such as for example a bolt with thread, with its sharpened end for facilitate its penetration, etc.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a representation according to a general perspective of the leg of the invention, looking like It consists of an extruded profile with an insert or bolt with upper thread and a lower cover.

Figure 2.- Shows a perspective view of the upper end of the leg in which the insert has been varied metal.

Figure 3.- Shows the lower end of the leg with the incorporation of a wheel to support the ground.

Figure 4.- Shows an elevation view side of the wheel represented in the previous figure, with the stem or screw fixing to the corresponding leg.

Figure 5.- Shows a perspective view of the leg using co-extrusion technology to incorporate a soul of a recycled or second material quality, also showing the microbubbles generated in the soul as a result of the foaming agent.

Figure 6.- Shows a sectional view. transverse of the leg of the invention provided with channels, in this case of through circular holes, to lighten the same.

Preferred Embodiment of the Invention

As you can see in the referred figures, the leg (1) of the invention, intended for application in bases and / or canapés and bed bases, is based on a manufacturing process by extrusion, obtaining an extruded cylindrical profile that corresponds to the reference itself (1), at one of whose ends incorporates a striated insert (2) with an upper and emergent section (2 ') which is threaded for fixing to the corresponding bed base or base on which it is applied, while at its lower end it is capable of being complemented with a support cover (3), fixed by means of a stud or rod (4), or instead of the cover (3) incorporate a wheel (5) with a support (6) from which a shank with screw (7) fixing to the lower end of the own leg (1).

As for the insert (2), instead of being materialized by a spline bolt, as depicted in the Figure 1, can be defined by a section (2 '') with fillet Thread and pointed end for easy penetration, keeping the emerging part (2 ') of fixation to the corresponding box spring or base.

Obviously, that bolt (2), stem or any element (2 ''), can have one or another embodiment or configuration, since it is only intended for screw fixing or any other system to the end lower leg.

As already stated, leg (1) can use the technology called co-extrusion, in which In addition to being obtained by extrusion, you can use a recycled or second quality material without dye and with addition of foaming agents, constituting a soul (1 ') of the constituent profile of the leg (1) proper, as shown in the figure 5. The addition of foaming agents or other equivalent chemical agents Its main objective is the generation of cavities or microbubbles in the constitutive mass of the soul (1 '), which results in in a decrease in the total weight of the leg (1).

Finally, it is expected that the leg can be provided with holes or emptying (8) of lightening, as shown in the section of figure 6, holes that correspond to longitudinal channels of any section and that they also allow obtaining a leg profile (1) with lower weight.

Claims (2)

1. Leg for rest equipment, which being intended for preferential application in mattress bases and bed bases, is characterized in that it is constituted by an extruded cylindrical profile on whose upper end incorporates a metal insert with a threaded external section for fixing to the corresponding bed base or base, while its lower end is capable of incorporating a support cover or a displacement wheel, it being provided that the fundamental cylindrical profile can be constituted by co-extrusion with a core of a recyclable or second quality material , which optionally includes a foaming agent inside. 2. Leg for rest equipment, according to previous claims, characterized in that it is axially and longitudinally affected by lightening channels or holes.
