Abstract
This device acts on each of two ropes in a mutually opposite sense. For each rope the device includes a pivotably mounted arm, and the two arms are arranged in a converging arrangement and thus converge towards their free ends and are adapted to be simultaneously actuated by a pushbutton operable for pressing them at their free ends. The pushbutton includes a spring arranged to bias the pushbutton away from the arms and each of the ropes is secured to the free end of a respective one of the arms, these latter being pivotably mounted to a tubular body with the ropes extending through its inside. A cowling is arranged on the tubular body and has an opening in which the pushbutton is guided during its actuation.
Description

BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings:



FIG. 1 illustrates in an elevational view the main components of the device being the object of the invention;



FIGS. 2 and 3 in an elevational section depict the whole device being arranged in its passive and in its active arrangement, respectively; and



FIG. 4 diagrammatically shows in a plan-view the device being fitted to a tubular body also having fitted to it another device of the already known type for the actuation of each of several mechanisms through a respective rope.





DETAILED DESCRIPTION OF THE INVENTION

According to the drawings the device for the actuation of each of several mechanisms through a respective rope comprises two arms (1) and (2) being each at one of its ends linked in a pin-jointed connection by means of a respective pin (3) and (4) to a tubular body (5), said arms being arranged in a converging arrangement and thus converging towards their free ends (6) and (7), each of these latter having the end of a respective rope (8) and (9) secured to it, each of said ropes extending into the inside of the tubular body (5) through a respective orifice (10) and (11) being provided in it.


These two arms (1) and (2) are simultaneously actuated by the action being exerted by a pushbutton (12) being operable for pressing them at their ends (6) and (7).


On the tubular body (5) a cowling (13) is fitted which has an opening (14) shiftingly guiding the pushbutton (12) during its actuation (FIGS. 2 and 3), this latter in its inside comprising a spring (15) being fit to biassedly keep it arranged in its passive arrangement.


In the case being shown the tubular body (5) makes up the middle length of the handle belonging to a carrycot seat or a carrycot being adapted to be fitted to a pram.


In FIG. 4 another device (16) of an already known type is fitted to the tubular body (5) and also allows to simultaneously actuate two mechanisms being actuated by the ropes (17) and (18).


In this concrete case one of these devices will act on the mechanisms being provided for removably fitting the carrycot seat or carrycot to the pram and the other device will act to thereby lock the angular arrangement being chosen for the handle being articulately linked to the carrycot seat or carrycot.


In the device being the object of the invention when pressing the pushbutton (12) as per arrow F (FIG. 1) both arms (1) and (2) will be simultaneously pushed at their ends (6) and (7) and will be thus turned around their pins (3) and (4) as per arrows F′ thus pulling the ropes (8) and (9) as per arrows F″.


Once the action being exerted on the pushbutton (12) has ceased the ropes (8) and (9) will shiftingly move in the opposite sense due to the action of the actual mechanisms to which they are linked, the pushbutton (12) thus regaining its passive position (FIG. 2).

Claims
  • 1. A device for the actuation of mechanisms each through a respective rope by acting on each of two ropes in a mutually opposite sense, comprising a respective pivotably mounted arm for each rope, the two arms being arranged in a converging arrangement and thus converging towards their free ends, and a pushbutton arranged to simultaneously actuate the arms by pressing the arms at said free ends.
  • 2. A device according to claim 1, wherein the pushbutton comprises a spring arranged to bias the pushbutton away from the free ends of the arms.
  • 3. A device according to claim 1, further comprising a tubular body and wherein each of the ropes is secured to the free end of the respective one of the arms, the arms being pivotably mounted to walls of the tubular body and the ropes extending through an interior of the tubular body.
  • 4. A device according to claim 3, further comprising a cowling arranged on the tubular body and having an opening for guiding the pushbutton during its actuation.
  • 5. An actuation device, comprising two arms mounted for pivoting in substantially the same plane, the arms each having a free end proximate to which a respective rope is attached, the arms being pivotable between first and second positions, the free ends of the arms being closer to each other at the first position than at the second position, an actuator mounted between the arms for manual actuation so as to substantially simultaneously engage both of the arms proximate the free ends thereof thereby to pivot the arms from the first position to the second position and draw the ropes toward each other.
  • 6. An actuator device according to claim 5, wherein the actuator comprises a pushbutton and a spring biasing the pushbutton away from the free ends of the arms.
  • 7. An actuation device according to claim 6, further comprising a tubular body to walls of which the arms are pivotably mounted and through which the ropes are conducted.
  • 8. An actuation device according to claim 7, further comprising a cowling surrounding at least a portion of the tubular body to which the arms are pivotably mounted and the cowling having a tubular opening through a wall of the cowling for receiving and guiding the pushbutton for movement of the pushbutton toward and away from the free ends of the arms.
