Definitions

  • the invention relates to a scale, more particularly intended for toys. It relates in particular to a scale intended to adapt to a load-bearing element, such as for example a truck, a horse, etc., on which a child is likely to sit.
  • a load-bearing element such as for example a truck, a horse, etc.
  • rocking toys generally do not include an amplitude adjustment device.
  • these rocking toys can be relatively dangerous for children, since when the tilting amplitude becomes too high, the instability of the toy, sometimes sought increases the risk of falling of the toy, and therefore of the child.
  • rocking toys were then proposed comprising a fixed stop, secured to the rocker either at the front or at the rear, then limiting the amplitude according to a value determined by the manufacturer.
  • This fixed stop is either snap-on on the frame of the rocker, or fixable on the latter by any other fixing means, or can also be obtained from molding. It has the drawback of limiting the tilting amplitude to a well-defined value, without proposing intermediate values, adaptable for example according to the progress of the child's balance.
  • a toy or a baby chair also capable of tilting, comprising two side members having at each of their two ends a cam, intended to limit the amplitude of the tilting.
  • this cam is capable of pivoting around the cross member of section circular, so that, when it is subjected to the forces generated by the actual tilting, it pivots around the beam, so that once again, no intermediate position of the cam can be obtained, and therefore, no amplitude Tipping intermediary cannot be reached.
  • This system therefore works again according to two possible tilting amplitudes, namely according to a first position of the cams, fully pivoted around the side members, and allowing a maximum amplitude, and a second position, in which the cams come into immediate abutment with the ground. , strongly prohibiting or limiting tilting.
  • the cam can be locked in the intermediate position by means of a ring, capable of sliding along the cylindrical spar.
  • systems are not proposed which are capable of varying the degree of amplitude, which is both simple to implement and reliable.
  • the invention aims to overcome these drawbacks. It offers a rocker, the amplitude of which can be varied in a simple and progressive manner.
  • This rocker in particular for a toy, comprises two parallel arched longitudinal members, integral with one another, each longitudinal member comprising in the vicinity of its two ends an articulated cam.
  • This rocker on which the carrier element is positioned in particular a truck, a horse, etc., can be attached under the toy, or it is integral with the toy.
  • each cam is capable of extending in an adjustable and progressive manner along the vertical plane perpendicular to the corresponding spar by pivoting around a horizontal axis integrated in said spar, the adjustment of the cam is effecting by means of a handle formed at the level of the external lateral face of the spar, secured to the cam along the axis of articulation of the latter.
  • the invention consists in providing each of the ends of the two longitudinal members constituting the rocker with a cam, adjustable in travel by means of an external handle, so as to be able to limit in an adjustable manner the amplitude of tilting of the side members and therefore of the rocker.
  • the cam when the rocker is in the position of maximum amplitude, the cam is completely retractable inside the spar.
  • the assembly constituted by the handle and the cam is in one piece, the spar consisting of two parts, welded at a weld line after the cam / handle assembly has been put in place.
  • the handle is provided with a stud, which cooperates with orifices provided on the external lateral face of the spar, advantageously located in an arc of a circle and positioned at 20 ° from each other.
  • the cam is provided with an elastic spring, intended to oppose the withdrawal of the handle and in particular of the stud from the adjustment orifice.
  • the spring is a leaf spring, integral with the cam and resulting from molding.
  • the cams are positioned symmetrically with respect to the axis of equilibrium of the beam and aligned two by two from one beam to the other.
  • the cams are made of a resistant material, for example polypropylene or polyoxymethylene. These easy-to-mold materials have the resistance necessary for wear and for the stresses generated during tilting.
  • Figure 1 is a schematic representation of a side view of the scale according to the invention.
  • Figure 2 is a schematic representation seen from above of a spar of the invention.
  • FIG. 3 is a schematic sectional representation of the cam provided with its handle according to the invention.
  • the lever consists of two parallel beams (1) integral with each other, of arcuate shape, and resting on the ground on the side of their curvature.
  • These two side members thus constituting a rocker, are intended to receive a bearing element, such as for example a truck, a horse, or any type of equivalent device, intended to receive a child.
  • a bearing element such as for example a truck, a horse, or any type of equivalent device, intended to receive a child.
  • a bearing element such as for example a truck, a horse, or any type of equivalent device
  • the carrier device can thus tilt in view of the arched shape of the side members, in a known manner.
  • each of the side members receives at its ends, symmetrically with respect to the equilibrium plane referenced (10), a cam (4) of oval shape, intended to deploy in the vertical plane at vertical to the spar.
  • This cam is articulated at a horizontal articulation axis (5), capable of allowing its extension to be adjusted in said vertical plane containing the longitudinal member (1) considered, as can be clearly seen in FIG. 1 , where different possible positions of the cam (4) have been shown.
  • This cam is intended to reduce the amplitude of tilting of the side members (1) between two extreme positions, namely a first position in which the anterior and posterior cams are vertical and bear on the ground, so that the whole of the rocker is blocked and can no longer tilt, and a fully retracted position inside the side member, allowing maximum tilting.
  • the cams (4) can be adjusted according to different intermediate positions, by means of a handle (7), as best shown in FIG. 3.
  • This handle (7) formed on the wall lateral lateral side member, is integral with the cam (4) at one of its ends by an axis (11), itself collinear with the axis (5) of articulation of the cam (4) on the side member (1).
  • the handle (7) has at its face opposite said spar a stud (8), or equivalent member, intended to cooperate with orifices (6) formed in the external lateral face of the spar (1).
  • this articulated handle (7) integral with the cam (4) describes a disk sector, and therefore the corresponding stud (8), located at one of the ends of said handle (7), opposite to that receiving the articulation axis (11), describes an arc of circle which can typically reach 80 °.
  • the holes (6) are drilled at the side member every 20 ° so as to have approximately three possible intermediate adjustment positions. It goes without saying that more can be provided, it suffices for this to provide more orifices (6), spaced by a lesser distance.
  • the cam / handle assembly is provided with a spring (9), inducing in the absence of stress, the retention of the stud in place in the chosen opening.
  • the spring (9) exerts its compression action between the cam (4) and the inner lateral face of the beam (1). In this way, it tends to oppose the spacing of the handle (7) of the external lateral face of said spar, and therefore, at the outlet of the stud (8) outside the orifice (6) selected.
  • the spring (9) is advantageously chosen so that the thrust it exerts is large enough to prohibit the selection of the orifice (6) by children, likely to play with this toy.
  • this spring (9) comes from molding and is integral with the cam (4), as clearly shown in FIG. 3.
  • This leaf spring with memory effect therefore induces the maintenance of the handle (7) in the desired position.
  • the assembly constituted by the cam (4), the pin (11), the handle (7), the stud (8) and the spring (9) is in one piece and comes from the molding.
  • the assembly constituted by the cam and the handle is made of polypropylene, and more particularly of polyoxymethylene, sold under the registered trademark DELRIN (DUPONT DE NEMOURS).
  • the four cams namely the anterior and posterior cams of each of the two side members, are strictly identical, thereby simplifying the production of the device. They are as already said located on either side and symmetrically with respect to the plane (10) of equilibrium of each beam, and parallel two by two between the two beams.
  • the thickness of each of the cams is close to 14 mm, each cam thus being rigid enough to provide the resistance necessary for tilting, taking into account the weight of the child.
