Abstract

The present invention relates to a toy in the form of a helical spring formed of a single continuous strip (11) of small thickness and of a width of the order of 0.6% of the maximum outside diameter of the reference spring. These springs can have a cylindrical (10) or polygonal tubular helical format or else a spiral helical format.

Description

-1- The present invention relates to a new

  toy in the form of a helical spring.

  Toys in the form of a helical spring with a cylindrical tubular configuration are already known.

  are composed of a continuous strip arranged helically-

  ment, which has a certain flexibility nour allow a deformation ce its turns when ies those ends of the spring are manipulated by both hands

  from the same user or by the hands of two different users

  rents, producing in this way a series of movements

  continuous, wave-like or not, pleasant to see and fun

health.

  We know that these toys of the prior art

  only allow a limited range of movements of their turns when the toy is subjected to a determined movement on the part of the user. These toys therefore present a considerable limitation as to the richness of

  movements presented by their turns during their use.

  This limitation of movements is normally due to the fact that the turns are double and composed of materials

hard metal.

  The duplication of the turns tends to cause their own entanglement during the use of the toy by considerably interfering with the elastic movement of the turns and, consequently, of the strip. In addition, the use of hard metallic materials causes a movement of

  unpleasantly noisy, heavy and inconvenient turns.

  The present invention aims to create a toy in the form of an elongated helical spring of reduced weight and which allows, during its manipulation by a user, to

  produce a wide range of harmonic movements, amu-

  healthy and relaxing without the risk of tangle of turns and without producing unpleasant contrasting noises

  with the harmony of movements that will be possible

hold on.

  This object is achieved according to the present invention

  by means of a toy in the form of a coiled spring

  led by a continuous strip of plastic

  high odor, with a rectangular cross-section

  gular of small thickness and whose width is

  about 0.6% of the maximum outside diameter of the res-

  comes out. The invention will be better understood if one observes all of the accompanying drawings in which: FIG. 1 represents a perspective view of a toy conforming to the invention in the form of a cylindrical tubular helical spring; 2 shows a side elevational view of the same spring illustrated in Figure 1, but in a state of rest after its upper end has undergone a rotation of 1800 and has been placed laterally at the same level as the lower base of the spring; FIG. 3 represents a side elevation view of the same spring illustrated in FIG. 1, during a series of wave movements carried out on different successive levels; 4 shows a perspective view of a toy according to the present invention, in the form of a tubular helical spring of polygonal hexagonal cross section in the rest state; FIG. 5 represents a perspective view of a toy according to the present invention in the form of a

  tubular coil spring with cross section for

  octagonal lygonal and in resting state; FIG. 6 represents a perspective view of a toy in accordance with the present invention in the form of a tubular helical spring of helical configuration and of a hexagonal polygonal cross section twisted and completely compressed;

  Figure 7 shows a top plan view

  laughing of a toy according to the present invention in the form of a helical spring of conical configuration also in a state of rest; FIG. 8 represents a side elevation view of the same spring illustrated in FIG. 7, with its base mounted on a sort of racket; Figure 8 further representing, so-us exploded form, a hook

  optionally incorporated at the top of the spring and replaced

  racking the racket; and FIG. 9 represents an elevation view of the same spring illustrated in FIGS. 7 and 8, in the rest state. As shown in the accompanying drawings, the toy according to the present invention consists of a spring 10, 20, 30, 40 and 50 formed by a single continuous strip 11, 21, 31, 41 and 51 developed helically and made of plastic of high stiffness with a rectangular cross section of very small thickness and a width of the order of 0.6% of the diameter

maximum outside of the spring.

  In the tubular helical configurations of Figures 1, 2, 3, 4, 5 and 6, the spring bands

  , 20, 30 and 40 are developed in the form of coiled loops

  tied against each other at their main faces when the springs are in a rest position. Tubular coil springs 10, 20, 30

  and 40 illustrated in FIGS. 1 to 6 allow the reaction

  reading on a plane of wave movements of di-

  pouring intensities when their ends are transversely displaced in reciprocal movements by the user

  or the users The tubular coil springs per-

  still put getting wave movements

  when going down steps, as shown in the figure

  gure 3 or even the formation of, different curves

  like the one illustrated in figure 2.

  The coil springs in Figures 7, 8 and 9

  allow reciprocal axial movements

  thanks to their spiral conformation, since during these reciprocal axial movements the spiral coil springs execute the movement illustrated in Figure 8, passing through an intermediate state

  neutral of rest illustrated in figures 7 and 9.

  In the example of figure 8, we can see a

  ring 52 fixed to the base of the spiral coil spring

  rale 50, and which incorporates a connecting handle 53 so

  lesson in defining a structure of the open racket type, through which the helical coil spring moves from one side to the other when subjected to a

  certain movement applied to the racket by the user.

  This spiral helical spring 50 can optionally be fixed, by its top, to a hook of

  manual link 54 to perform reciprocal movements

axial with the spring.
