All these fottt-opefotsb door opening devices kxtpwn fforn; The prior art have the common {estate that: They on the one hand enable a relatively rough sad not iseiy tuned, opening of the doorhy means of a foot and lurtherxnorc are linked to a eertalxt potential for injury daring operádon as a resti is of the in part bulky' geometry.

The Inyfcxttidn is therefore concensed witis the problem of avoidings at least in part the aiorexaentioned disadvantages.. This prplrism oxs which the; invention ;is based; is solved^ by a; foph operates door opener according to site jxtvetmon according to Claim I as wéll ás by a door aeeordlxtg to cluim: IT and a use according to claim 18,

The toot-operated door opener accord log so the invention is fined with a feet actuator ekmetn arranged its the fewer region of a door to open she door. It is hereby advamageous that the loot-operated deer opener when not operated Is substantially free of any projection beyond the door profik, i.e. that the foot-operated doer opener dees not project over the door profik. As a result of this configurators the risk of «fiery k markedly reduced since there are m awkward ekntems protruding from tin; door.

The avoidance of assy parts protruding beyond she door profik is aehkved by way of example and more particularly in that the foot actuator ekossent has at least one foot surface desneoi which in «se is pivoted at kast partially snwards so that tbs user by placing hts toot on the font snrfaec: element. which a rale is designed like a phase, and pressing It down, also causes a pivotal movement towards she inside so that a relatively finely motorised actuation is ako hereby possible for slowly opetting: the: corresponding. door sines pivotal movossreuts as a rs.sk, and seen physfelogieaMy, can be snore finely metered than purely trpslatipn movements.

The foot-operated door-opener according to the invention is comprised of several esmsifineítiípatts, more: pariiotfiariy of a Toot actuator element, which has by way of uxasnpls and more particularly a foot surface element which as a ntk is plate-shaped, and an actuator element which in: general translates the pivotal movement and reproduces It in the .form of a translation movement wherein the actuator element is often designed in the farm of a rod or cable so that by fixing the actuator element on a conventional door opening stseehanisns sad by operating the foot actuator element the door can time be opened via she actuator element and the engagement on the opening nsechunisnt of a door

The individual parts of the foot-operated door opener according to the Invention cats more particularly he of a metal type, by way of example and its particular of stainless steel or aluminium alloys, it Is essentsal to the invention that the foot actuator densesn has an uppet foot surface oktsestt add a lower foot spriaoe skfeertt wherein these are both us a rule designed like plates wherein these are connected to one another in nn atiiculated manner and upon foot actuation pivot at least partially in each case into tire interior of the door.

The pivotal movement of the two foot surface elements leads to a greater “space'’ inside the door so that any possible jamm ing at the ismer edges of the door is considerably redtseed. Through this special enufiguratfort is is easier for the over to open die corresponding door since a greater “step surface" - the surface to be stepped: on by the: foot - is asadabk for opening the door cotnpared to s configuratsots having only one foot surface element. Furthermore the risk of jatumfog whets withdrawing the foot, s\ lower through the larger “spstoe’f

Furthermore u Is garikukify advantageous according |:o the invention when at least one foot surface element Is guided1 in a guide slot,, if fit the upper fool surface elcfeghf is guided in a first guide slot aad tub lower fit# surface pieman its guided in a second guide slot, or vice versa,, or bj the upper and the lower foot surface elements are guided In one single guide slot, since a secure reproducible functionality -is hereby provided: ássd distortion ©1' the elements relative to one another .aaá a possible jamming Is thereby reduced to a minimum.

It is furthermore advantageous if the courses of the two guide slots ate different wherein it hits proved reliable to practice it the first and/or second guide slot has/havc a diagonal course, the sbeond guide slot lias a paraboloid-like course, a part of tho second guide slot hns a diagonal .course, a part of the second guide siót has a yertfeal course, as wall as the course of th® second guide slot having a parabobiddike course followed by a cortical: course and then a diagonal course, since with the aid of these GChigufatfons it is possible to adapt neeurately fofhe useful purpose each time with regard to the tlnely tnotorked controilaMUty.

Through dingnnafity, thus how far the courses run straight: and. inclined, and also: the type of paraboloid form, if is possible to adjust the ratio between the pi votal movement and: proportion of a translation movement, since as: a rule through the translation proportion during; the pivotal, htbeemeot this determines the ratio regarding the actuation of as opening tnoehaslstS:of the door, since as a: rule au actuator «lement, which is designed more particularly is the form of a rod or a. cable, functions directly df indirectly· as the intermediary ::®Cibi>er between the loot surface element or foot actuator element, and the actual opening mechanism of foe doer, jussi as hsl jfofoator elemeith

It is obviously also conceivable that other guide slot courses are: produced, by way of eymsxgle, that a first diagonal course m followed by a vertical course which in: turn is followed by a paraboioiddtfes bburse.

It is fortherrnore advantageous if the articulated; ednneeUoO: of the two foot sur&amp;ee; eletaents is realised by means of at least one guide: slot running element which is as a rule designed as n rod and runs as a rod in a guide slot, snore particularly Wherein the at least one guide slot running element is guided in the first or second guide slot or in a single guide slot. More particularly the first guide slot is that of the lower foot surface element, in fob way during pi votal movement of the lon er foot surface element a synchronised automatic pivoting of the upper foot surface element takes plage adapted to the guide slot course, which represents a sunpie but effective configuration as regards adapting the pivotal movement of the two foot surface elements relative to one another in dependence on the absolute pivotal movement of the lower too; surface element. it is likewise in accordance with the invention if (he foormpermed door opener has only one single; guide slot. if; is furthermore advantageous if at least a first spring element directly or indirectly engages on at least one foot surface element in such a way that the latter is drawn into a rest position without foot resistance from an operator, more advantageously in such a way that both foot surface elements dwell in a vertical position and thus la the ideal ease form a punas flush closure with the door surface. fa this connection It is advantageous if the courses of the two guide slots are different in such a way that releasing one foot: surface element causes: a retraction Into the rest position .with· at; least t partial irteítoháf guiding: of foe first m s further guide siót !fotniág: element síned in ibis way, depending on the geometric: arrangement and extent of the friction of the guide: slot naming element In the guide slot, a quasi dentped retraction mm the rest position is possible mám a rule n is avoided (hat the at least one spring element draws the: foot surface dements unbraked Into their rest: positions against corresponding stops, wine is is mostly connected wsth a high nosse level. fe jhts connection it is advantageous if the first spring elemem engages on the tarsi or on a further guide slot running dement.

It is furthermore adiamageonsJs this connection, sitsee this has proved itself in.:practice, if the first spring element or additionally a Ibritter second spring dlemehf directly or iodireeily eapps m an opening mechanism of the door. it. is furthermore mi·, uruageons if the spring constasds: of the two spring elements have dlfterent levels, more particularly if the spring: eonsttmis of the two spring elements are diflkietit from one: another in such a way that doting operation of the loot actuator element the door which is to be opened: is opened In a controlled manner, since thus a precision adjustment is possible between the opening of the opening mechanism of fbe dept and the degree of pivotal movement of the foot surface element or of the two fool sudden elements, By way of example It is cenoelyable Bp two spring elements are connected in series and in alternating action with one another, so that then as a result of a relatively tow spring constant: and thus a relaitvely high resilience of the first spring efentest beyond a rchniveiy high spring constant, the second spring dented: is extended relatively less with the same application of force and thett: front a certain point of the pivotal movement the resulting Iraaslafcry path ό|· dnrmg a rotational movement: the corresponding rotational path is suffieient In order to actuate the doer mechanism of the door in such a way that this can:be? opened, it is furthermore: conceivable that instead of spring dements dampers such as gas compression dampers or coil compression dampers are used.

The invention will stow be described in non-limning manner with reference to an ehihpdimént and the fdttr figures which refute thereto,: wherein

The two spring elements 8 and 11 are connected to hook into one another (at point 18), wherein the second spring element If is directly connected to an upper Éame part of the foot actuator element 1. As a result of the fact that the foot actuator element 1 has two footstep guide slots A anti B with identical structure but drfferent alignment the cable element 12 runs in each ease seen from a footstep guide slot further over the guide pulley id m that the: cable element 12 Is finally cooueeted ut the two guide slot rtthhing elements 10.
