AN ARRANGEMENT FOR THE ASSEMBLY OF FRONTAL HANDRAILS TO CHILDREN'S PUSHCHAIRS OR STROLLERS

Abstract: The invention concerns an arrangement for assembling frontal handrails to children's pushchairs or strollers. Al­ though the known arrangements for the assembly of the handrails perform such a function generally they have a complex structure and are very difficult to be handled by women. Therefore, the object to be solved by this invention is to provide a very simple arrangement for the assembly of the handrails being easily engaged and disengaged by only pressing a flexible retainer. This object is solved by a structure characterized in that the handrail (1) at least shows at one of the handrail sides a box component (6, 7) with a lower opening being detachably inserted into a shank (10) provided in a frontal housing (21) of the associated armrest (9) of the pushchair or stroller, this insertion to be eventually kept up by a flexible retainer (18) also provided in said housing, a tooth (8) of the box component (6, 7) engaging therefrom.

Description: The present invention refers to an arrangement for assembling frontal handrails to childrens's pushchairs or strollers. For several years are already known in the art several types of frontal handrails detachably engageable to the armrests of the pushchair or stroller or either detachably engageable to an end while in the other they are being pivotedly fitted,all that to have the child easily placed and removed at the pushchair or stroller whereas an arrangement for a carrycot on the pushchair or stroller seat can also be available when the seatback is reclined backwardly. Although the known arrangements for the assembly of the handrails perform such a function generally they have a complex structure, albeit being antiaesthetic,and become very difficult to be handled by housewifes or people in charge of a child,some of these arrangements have externally projected members and can thus be a cause for injuries or damages to the child. The present patent refers to a very simple arrangement being easily engaged and disengaged by only depressing a flexible retainer. The structure of this arrangement enables it to be advantageously applied to a frontal handrail placed at the pushchair or stroller being the object of the Spanish Utility Model no. 275 941 of the same applicant, the handrail is pivoting by its ends onto the upper end of a tierod combining the armrest with the frontal leg of the pushchair or stroller. This new arrangement is essentially characterized in that a box component with an opening at the bottom part is provided at least at one of the ends of the handrail for being detachably inserted into a shank made up by the upper end of said tierod and being located at a frontal housing in the associated armrest, this insertion being eventually kept up by means of a flexible retainer, a tooth of said box component is engaging therefrom. It is also provided the box component with an upper opening to be intrlocked with the pushchair or stroller sidemember and the shank to be a portion of a pivoted component at the end of the handrail, this component to be a retainer-holder for engagement with the tooth provided in the shankholder component. These and other characteristics should be better understood in the following details of the description by reference to the attached drawing sheet wherein a preferred embodiment is shown only by way of non-exhaustive example of the scope of the present patent. In the drawings: Figure 1 shows a perspective view of the whole of this arrangement with the handrail not engaged. Figure 2 shows in an elevation view said arrangement with the handrail engaged to the armrest. Figure 3 also shows in a perspective view and while not en gaged another version of the arrangement and Figure 4 shows in a larger scaled elevation cross-sectioned view said version with the arrangement engaged. Referring to the drawings, handrail-l- comprises a core-2made up with several mutually pivoted lengths and covered by a stuffed sheath-3-.At least one of the ends of the handrail shows at the top ring-4- the pivoting effect by means of a pin -5- of a component-6- making up the box-7- with a lower opening and comprising a tooth--8-at the external side. In the engaging of the handrail to the armrest-9- the box component-6-7- is engaged on a flat shank-l0- made up by the inflectioned upper end of a tierod-ll- pivotedly associating the armrest to the front leg-12-,whereby said tierod is pivoted in the armrest on being crossed by an armrest transversally interlocked shaft-13-and is pivoted to the front leg on being downwardly crossed by a pin-14- in turn crossing the lugs-15of a flange-16- locked by means of rivets-17- to the leg. Eventual retention of the box component in the shank-l0is achieved by means of a flexible retainer-18- interlocked to a bushing-19- strung onto the shaft-13- and showing a tooth-20at the inMrnal side which is engaging onto the tooth-8- of the box component-6-. The shank-l0-, the engaged box component-6- and the retainer -18- are at a frontal housing -21- of the armrest, a retainer terminal -22- upwardly being projected therefrom for access to the retainer, this retainer on being laterally separated releases the box component and thus the handrail can be detached. The handrail engagement is automatically performed upon engaging the box component-6- into the shank-lu- since in the downwardly motion of said component, the lower inclined plane shown by the tooth-8- laterally separates the flexible retainer -18- in a way such as when said tooth overrides the tooth-20- of the retainer, the retainer is resiliently retrieved by said tooth-20engaging onto the one of the component-6-. One of said rivets-17- makes up the pivoting shaft of the front leg-12- to the side-23- of a flexible seat-24-. By numeral -25- is shown a profile of plastic materiaI decoratively covering the tierod-ll-and by numeral-26- is shown a decorative plate engaged into the armrest external side. As seen in the version of the figures 3 and 4 the arrangement for the assembly of the handrail comprises a pIastic material moulded component -6'- which is overlapped and clamped on the tierod-ll- pivotedly associating the frontal end of the armrest-9'- with the frontal leg-12-, which leg is being pivoted to the side-23- of the frame of the pushchair or stroller1 s seat -24-, said seat comprising sides-24'- being folded on the armrests by making up some lips -27- showing fastening means-28-. Said component-6'- at the upper half shows a thickening making up a box-7'- with an upper opening-7"- frontally compris ing a tooth-8'-. Said box is provided with a flat shank-l0'downwardly interlocked to one component-29- linked by a hinge -5- to the endpiece-4- of the frontal handrail being covered by a stuffed sheath-3-, said handrail being made up with several mutually pivoted components to allow transversal folding of the pushchair or stroller. The holding component of the shank-lû'- comprises the positioning of a flexible retiner-18'- involving an engaging tooth -20'- into the tooth-8'- of the component-6'-, said retainer extending along by making up a gripping appendage-22'-. As figure 3 is also illustrating, to engage the handrail it would be sufficient to insert the shank-l0'- in the box-7'- automatically engaging the tooth-20'- of the retainer into the tooth-8'- of the component-6'-. The handrail is disengaged by pulling the appendage-22'from the retainer and the disengagement is thus obtained and then the shank-l0- can be freely released as regards the box of the component-6'-. This arrangement can be provided in only one of the handrail ends or either in the two handrail ends, in the first case the other handrail end must be pivoted to the armrest so that the child is easily placed and removed. In the second case, with the handrail removed a carrycot can be provided and fitted on the pushchair or stroller seat when the child is still very young or a totter. The handrail due to the pivoting joints allows the pushchair or stroller to be folded both downwardly as transversally. The patent within its essentiality can practically be embodied in other ways of performance only differing in detail from the one shown herein by way of example to which other ways the protection applied for shall also be extended to. This arrangement therefore can be manufactured for the assembly of frontal handrails to children's pushchair or strollers, in any size or shape with the most suitable means and materials and most convenient accessories since alI that is comprised in the scope of the following claims.
