FOLDING WHEEL FOR FURNITURE OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a folding wheel for furniture. It presents characteristic advantages of novelty, which will be described in detail below, which are an alternative in the current state of the art.

The object of the present invention falls on a folding wheel for furniture, attachable on any furniture already manufactured, especially by the end user.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the furniture manufacturing and modification sector, whether for domestic or office use.

BACKGROUND OF THE INVENTION

As a reference to the current state of the art, it should be noted that commercially available furniture, tables, cabinets, sideboards, etc. It is sometimes heavy and difficult to move. However, for reasons of hygiene it is necessary to move it to be able to sweep, scrub or remove the dirt that accumulates.

On other occasions, it is the accidental broth of an object that requires moving the furniture to recover it.

There are in the market some skates that can be placed under the furniture for these functions. However, they force to lift the furniture to introduce them, and it is not possible to leave them placed by breaking the aesthetic.

Well, the objective of the present invention is to develop a collapsible and hidden wheel that facilitates the movement of the furniture without damaging its appearance, it should be noted that, at least by the applicants, the existence of any other device that presents is unknown technical or structural characteristics equal or similar to those presented by the one now proposed and as claimed.

EXPLANATION OF THE INVENTION

The wheel that the invention proposes is thus configured as a novelty within its field of application, the distinguishing details being conveniently set forth in the final claims that accompany this specification.

The folding wheel for furniture of the invention comprises an elongated housing with protrusions on the outside to be secured inside the furniture. As a preferred example, projections of cradle section are preferred. Inside the housing is arranged a spring that drives a base against an annular stop that closes the housing. Therefore, the annular stop is disposed at the end of the housing. For its part, the base has a sphere inside, with a free turning capacity inside said base, and which appears from that base on the side of the annular stop.

The wheel can be adjusted by changing the spring, or by arranging a worm, adjacent to the inside wall of the housing and threaded inside. This screw can be, for example, tubular or be formed by several parallel plates. The spring must rest on the base and on a threaded element mounted inside the screw. Thus, the rotation of the base will cause the screw to rotate and the movement of the threaded element, tensioning or tensioning the spring.

The described collapsible wheel consists of an innovative invention of characteristics unknown until now for the purpose to which it is intended, reasons that, together with its practical utility, provide it with sufficient grounds for

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a descriptive set of drawings is attached as an integral part thereof, with an illustrative character and non-limiting the following has been represented:

Figure number 1.- Shows an exploded view of the wheel in a first example of embodiment of the object of the invention, appreciating the parts and elements it comprises and its disposition;

Figure number 2.- Shows a perspective view of a piece of furniture with four wheels attached, according to the previous example; Y

Figure number 3.- Shows a section of a piece of furniture showing the position of the wheel of the example of figure 1.

PREFERRED EMBODIMENT OF THE INVENTION

The wheel shown in the example of Figure 1 comprises an elongated housing (1), normally circular in section to facilitate insertion into the furniture. This housing (1) has locking projections (2) to ensure its position once inserted. In figures 1 and 3, these projections (2) are four cribs, but the shape and quantity of said projections (2) can be varied.

The housing (1) is hollow to admit a spring (3), which on one end rests on one end of the housing (1) and on the other on a base (4) that carries a sphere (5). The base (4) is arranged inside one end of the housing (1) and a complementary annular stop (6) prevents its exit from it. The sphere (5) must appear from the base (4) on the side of the annular stop (6), and can rotate

freely within said base (4).

In use, the housing (1) is inserted and fixed inside the base of the furniture (7), so that the annular stop (6) is approximately flush with it. Several wheels should be placed on each piece of furniture (7), generally depending on the total weight of the same.

When the furniture (7) is at rest, the weight of the furniture (7) forces the base (4) and the sphere (5) to hide inside the housing (1) against the spring action (3 ).

If you want to move the furniture (7), it should be lifted slightly with the help of the springs (3) of the different wheels installed. At that time, the sphere (5) of each wheel appears and serves as a multidirectional wheel for the movement of the furniture (7). Therefore, by configuring the force of the spring (3), the effort required to move the furniture (7) can be controlled.

The spring (3) of the wheel can be replaced by a stronger or weaker one by removing the ring stop (6) and the base (4), which allows adjusting the wheel assistance. A second variant consists in arranging a screw (not shown) in the inner wall of the housing (1) and integral with the base (4), while the other end of the spring (3) is supported by a threaded element. Thus, the user can change the internal length available for the spring (3) by turning the base (4), and by pressing or distending the said spring (3).]

Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other modes of realization that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify its fundamental principle .

Claims (3)

R E I V I N D I C A C I O N E S 1. - Folding wheel for furniture, characterized in that it comprises an elongated housing (1) with protrusions (2) on the outside, which contains a spring (3) 5 that drives a base (4) against an annular stop (6) at one end of the housing (1), said base (4) presenting in its interior a sphere (5) capable of free spin that appears on the side of an annular stop (6). 2. - Wheel, folding for furniture according to claim 1, characterized 10 because the base (4) is integral with an internally threaded screw and adjacent to the inner wall of the housing (1), and because the spring (3) is supported on a threaded element on the side opposite the base (4). 3. - Wheel, folding for furniture according to claim 1, characterized in that the projections (2) have a cradle section.
