Definitions

  • the present invention concerns a motion two- or three-dimensional component absorbing and isolating, connecting element being applicable to machines and mechanical devices and implements, and particularly to portable machines and mechanical devices and implements being carried on the back by an operator and being provided with manipulating and/or control handles to be desirably isolated from the vibrations or alternating motions being generated by the machine.
  • the machines of this kind are frequently of the self-driven type, and thus they are actuated by an internal combustion engine being likely to transmit substantial vibrations to the machine frame or holder.
  • Many of these machines such as for example wreckers, vibrators, hedge cutters, etc., do as well include mechanisms being apt to generate vibration or reciprocating motions between different portions of the machine, these vibrations and/or motions a lso b eing 1 ikely t o b e transmitted to t he m achine frame o r h older, a nd from t his latter to the operator being all the time in contact wit the machine.
  • said vibrations and/or motions can in a short time cause a fatigue in the operator which in the long term can bring about a serious health problem.
  • Vibration absorbing systems are known which are based on resilient elements such as spring members, springs, rubber members, hydropneumatic devices, etc., and/or elastomer blocks. Their main problem is that when they absorb a motion component acting in one direction they at the same time accumulate the energy having been detracted from the system to thereupon release it thereby causing a rebound effect.
  • the elements being made of rubber or another elastomer have besides the drawback that they are only apt to admit movements within a relatively short travel.
  • Other vibration and motion absorbing elements or devices are based on the principle of the articulated parallelogram to absorb movements within fairly long travels. The drawback resides nevertheless in this case in the fact that the opposite sides of the parallelogram are submitted to motions bringing them closer together or farther apart from each other on top of the shifting motions.
  • Patent EP-A-0566436 discloses a device being apt to fixedly secure a load on a support and comprising at least a body being shaped as a band having a width being significantly bigger than its thickness, with two opposite, elongated lengths facing each other, said lengths being at a first end connected to each other through a curved link. The second ends of the elongated lengths make up fastening members being apt to be connected to the load and the support, respectively.
  • Said body is made up of several spring steel layers being sandwiched in elastomer layers and admits relative motions between the load and the support with at least two-dimensional components through resilient deformation. The above- mentioned problem of the accumulation of resilient energy and the consequent rebound effect are nevertheless still persisting due to the resilient nature of the body's material.
  • An object of the present invention is to provide a motion two- or three-dimensional component absorbing and isolating, connecting element being applicable to machines and mechanical devices and implements where said connecting element admits relative two- or three-dimensional motions within relatively long travels between a first and second portions of the machine or mechanical device or implement without accumulating resilient energy in significant amounts.
  • Another object of the present invention is to provide a motion two- or three- dimensional component absorbing and isolating, connecting element being applicable to machines and mechanical devices and implements where said connecting element is apt to be produced in an easy and quick way and at a low cost.
  • a motion two- or three-dimensional component absorbing and isolating, connecting element being applicable to machines and mechanical devices and implements.
  • the element is made up by at least a first body having an annular, elongated configuration and being shaped as a band having a width being significantly bigger than its thickness, said band being made of a resilient, tension resistant material and comprising two opposite, elongated lengths facing each other, said lengths being connected through curved end links, and first and second fastening members connecting said elongated lengths to respective first and second portions of a machine or mechanical device or implement being likely to effect relative motions having at least two-dimensional components.
  • said first body When facing said relative motions said first body operates by means of at least longitudinal shifting motions in opposite directions of the elongated lengths and of the first and second fastening members being attached to them and by means of motions of the elongated lengths which bring them closer together or farther apart from each other.
  • longitudinal shifting motions in opposite directions of the elongated lengths and by virtue of the resilient nature of the material of the bodies each of the elongated lengths progressively adopts the configuration of one of the curved links at an end whereas at the other end it is the curved link that progressively adopts the configuration of the elongated length, thereby acting much like a "track" type crawler tread.
  • connection member permits relative movements in any of the directions included in a plane, in other words, relative movements with at least two-dimensional components.
  • connection of said second attachment member to said second part of the machine, device or mechanical implement is made advantageously by means of a second body having generally an annular elongated shape similar to the first body described above, in other words, in the form a band with two opposed elongated sections, facing each other, linked by curved end sectors.
  • the second attachment member is connected to one of said elongated sections of the second body and a third attachment member connects the other of the elongated sections of the second body to said second part of the machine, device or mechanical implement.
  • Said second body is arranged forming an angle with respect to the first body, with the first and second parts being susceptible of relative movements with three-dimensional components.
  • the group of members works with regard to said relative movements by means of longitudinal movements, in opposed directions, of the respective elongated sections of the first and second bodies, and by means of approximation/distancing movements of the respective elongated sections.
  • said angle between the first and second bodies can be an acute angle, generally a right angle is preferred in order to have movement absorption members in the three directions of the three-dimensional space.
  • the relative movements between the first and second parts of the machine are alternative, of the vibrationary or reciprocal type, with strokes within a determined length range and they can adapt the annular elongated bodies of the member of the invention to said stroke length range upon selecting the length of the band and the features of material.
  • the member of this invention virtually eliminates the transmission of alternative three- dimensional linear movements as well as vibrations in all the magnitudes and frequencies thereof between first and second parts of a machine, device or mechanical implement.
  • Said flexible and tensile resistant material of the first and second bodies has, also, a low flexing fatigue coefficient, and it is selected together with the dimensions of the bodies in order to provide a predetermined resistance to the flattening in said curved end sectors.

Abstract

La présente invention a trait à un élément comportant un corps annulaire de forme allongée (10) sous la forme d'un anneau réalisé en un matériau élastique et résilient et définissant deux longueurs oblongues (12) opposées, lesdites longueurs étant reliées l'une à l'autre par des liens d'extrémité courbes (13). Des premier et deuxième organes d'attache (31, 32) relient lesdites longueurs oblongues (12) à des première et deuxième portions respectives aptes à assurer des mouvements relatifs. Ledit deuxième organe (32) relie de manière avantageuse le corps (10) à ladite deuxième portion à travers un deuxième corps (20) présentant une configuration analogue et à travers un troisième organe d'attache (33). Lorsqu'ils sont tournés vers les composants tridimensionnels, les corps (10, 20) fonctionnent par des mouvements de décalage longitudinaux des longueurs oblongues (12, 22) dans des directions mutuellement perpendiculaires (D1, D3) et par des mouvements des longueurs oblongues (12, 22) en une autre direction (D2) perpendiculaires aux précédentes, lesdits mouvements rapprochant ou espaçant lesdites longueurs l'une de l'autre.
