The drive gear comprises an input shaft rotatably mounted in a gear housing, which is rotatable about an axis by means of a drive lever between a locking position corresponding to a lowered position of the lifting slide element and a unlocking position corresponding to a raised position of the lifting slide element, wherein the input shaft can be coupled with a travel element for lifting and lowering the lifting slide element with a driving effect via a connecting rod. According to the invention, the drive gear mechanism further comprises a spring claw provided in the gear mechanism housing, by means of which the input shaft is locked in its locking position.
Description
Technical Field
The present invention relates to a drive gear mechanism for a lifting slide element, such as a lifting slide door or a lifting slide window, which is movable along a guide rail and can be moved from a lowered position into a raised position. In this lowered position, the lifting slide element is not movable. In this lifted position, the lifting slide element is movable along the guide rail. The drive gear has an input shaft which is rotatably mounted in a gear box, also referred to herein as a gear housing, and which can be rotated about an axis by means of a drive lever between a locking position, which corresponds to the lowered position of the lifting slide element, and a release position, which corresponds to the raised position of the lifting slide element, wherein the input shaft can be coupled with the travel element in a driving effect via a connecting rod.
Background
The travel elements for lifting and lowering the lifting slide elements described above are generally so-called mobile vehiclesThe movable carriage is disposed in a receiving portion formed at the lower side of the elevating slide member. The mobile carriage has a raised position and a lowered position, wherein in the lowered position the mobile carriage stands on the guide rail, thereby transferring the weight of the lifting slide element to the guide rail. Conversely, in the raised position, the contact of the mobile carriage with the rail is cancelled or the mobile carriage does not stand on the rail, so that the lifting slide element directly rests on the rail and the weight of the lifting slide element is transferred directly to the rail.
In this case, the drive of the mobile vehicle takes place by rotating the input shaft of the drive gear by means of the drive rod, wherein the rotational movement is transmitted to the mobile vehicle via the drive gear and the connecting rod coupled to the drive gear. When the mobile carriage is lowered from its raised position to its lowered position, the drive rod normally first performs an idle stroke over an angle of approximately 40 ° until the rollers of the mobile carriage stand on the guide rail. During the space-time travel, no or only a negligible friction force acts on the mobile vehicle and thus on the drive rod. Only when the drive lever continues to pivot after the idle stroke, the weight of the lifting slide element is loaded onto the mobile vehicle, so that a greater drive force or a greater drive torque is now required in order to lift the lifting slide element by means of the drive lever.
As already mentioned, the drive rod is essentially unstressed during the idle stroke, which results in that: if an operator accidentally hooks onto or rubs against the drive rod, the drive rod experiences an unexpected tilt. The risk of an unexpected tilting of the drive rod can also be intensified, for example, by a drive force reducing means, such as a (gas) spring, which reacts to the weight of the lifting slide element not only during the lowering of the lifting slide element but also during the lifting of the lifting slide element. With such a driving force reducing device, the driving rod may thus perform an idle stroke even without external force, tilting in an undesired manner.
Disclosure of Invention
The invention is therefore based on the object of: the drive gear mechanism of the type proposed at the beginning is improved such that no unintentional tilting of the drive rod occurs, especially in the case of the use of a drive force reducing device.
Based on a drive gear mechanism of the type mentioned at the outset, this object is achieved by the features of claim 1, in particular by: the drive gear further comprises a spring claw (Federraste) provided in the gear housing or the gear box, by means of which spring claw the input shaft is locked in its locking position. Such spring fingers are sometimes also referred to as latchesOr simply also just as a clasp +.>The spring fingers are contained in the gear box and thus form part of the drive gear.
Since the spring pawl is engageable with the input shaft in the locked position of the input shaft, the input shaft is held in the locked position of the input shaft against the torque applied to the input shaft by the braking force reducing device, whereby an unexpected inclination of the drive lever can be prevented.
Likewise, in case that an operator accidentally hooks at the driving lever or accidentally rubs the driving lever, an accidental inclination of the driving lever can be prevented by the spring claw. However, if the operator wants to lift the lifting slide element so that it can move along its guide rail, only a slightly greater driving force is applied to the brake lever by the operator or a slightly greater driving moment is applied to the input shaft in order to overcome the locking action of the spring pawl. Thereby, the spring fingers are disengaged or the spring fingers release the input shaft so that the input shaft can thereafter be freely rotated in a desired manner by means of the drive rod to lift the lifting slide element.
Thus, if it is mentioned here that the input shaft is secured in the locked position of the input shaft by means of a spring claw, this is to be understood as: the input shaft is locked in its locked position against accidental rotation, but conversely can be rotated out of its locked position in a desired manner under the application of large forces.
Now, preferred embodiments of the present invention are discussed below. Other embodiments may also be derived from the dependent claims, the description of the figures and the figures themselves.
Thus, according to one embodiment it may be proposed that: the spring pawl includes a first spring seat fixed at the gear box and thus fixed, and a second spring seat translatable relative to the first spring seat. The spring of the spring pawl is tensioned between the two spring seats, thereby tensioning or pushing the second spring seat against the input shaft. For example, the second spring seat may have a planar contact surface for contacting an likewise planar opposite contact surface which is arranged on the input shaft, wherein the contact surface of the second spring seat and the opposite contact surface of the input shaft are in contact with each other in the locking position. The two contact surfaces in question are in full contact with each other in the locking position of the input shaft, so that the input shaft can be locked in its locking position to a certain extent. More precisely, when the input shaft is rotated into its locking position, the input shaft is subjected to a certain restoring moment in the vicinity of its locking position by means of the spring fingers, by means of which the input shaft is pushed against and locked in the locking position.
According to a further embodiment, the spring claw may have a defined engagement element which engages in a form-fitting manner in at least one recess in the locking position of the input shaft, which recess is provided in or on the input shaft. According to a preferred embodiment it can be proposed that: the engagement element is located on the movable second spring seat. Alternatively, however, it is also possible that: a defined engagement element is formed on the input shaft, which engagement element engages in a corresponding recess on the second spring seat in the locked position of the input shaft.
In order to predefine a defined travel path for the second spring seat, along which the second spring seat can translate, it can be proposed according to a further embodiment: the first spring seat has a first spring seat and a first guide element extending from the first spring seat, and the second spring seat has a second spring seat and a second guide element extending from the second spring seat, the second guide element being translationally guided by the first guide element.
In order to be able to lock the spring against falling down (veriersicher) on the spring fingers, the spring can be supported on a first spring retainer and a second spring retainer and surround both guide elements. Thus, the spring is held in place by the two guide elements so that the spring does not disengage from the two spring races.
According to one embodiment, the first guiding element may for example be a pin extending from the first spring race, while the second guiding element may be a hollow cylinder extending from the second spring race and accommodating the pin. Alternatively, the second guide element may be a pin extending from the second spring retainer, and the first guide element may be a hollow cylinder extending from the first spring retainer and receiving the pin. Thus, as with the pistons of an internal combustion engine, the pins pass through the respective cylinders, whereby it is ensured that: the second spring seat can perform only translational stroke motions in a desired manner.
The direction of movement of the second spring seat is therefore not only predetermined by the spring path of the spring, but is determined by the two guide elements. Since the second spring seat is in contact with the input shaft of the drive gear mechanism, the second spring seat cannot deflect perpendicular to the spring path of the spring, which would otherwise lead to overstressing the spring pawl or even to its breaking.
According to a further embodiment, the engagement element can be provided as a primary cylinder, in particular as a needle, which cylinder/needle is rotatably supported on the second spring element. Thus, when the input shaft rotates, the second spring retainer is not dragged along the input shaft by sliding friction; in contrast, the cylinder or needle rollers roll along the outer circumference of the input shaft, so that undesirable wear phenomena on the second spring race or input shaft do not occur in the long term.
In order to be able to rotatably support the cylinder or needle, according to a further embodiment, the second spring retainer can have a nose (Steg) on its side opposite the second guide element, which nose protrudes perpendicularly to the face of the second spring retainer and forms a recess for rotatably supporting the needle or cylinder.
According to a further embodiment, the cylinder can protrude on both sides from the mentioned nose, and the input shaft has two hub sections axially spaced apart from one another, which each have a recess in which the sections of the cylinder protruding from the nose engage in a form-fitting manner in the locking position of the input shaft. The nose of the intermediate section of the second spring seat, which accommodates the cylinder, extends into the distance between the two hub sections of the input shaft, while the two protruding sections of the cylinder roll on the hub sections in order to be able to engage positively in the mentioned recess in the locking position of the input shaft.
In order to be able to lock the spring fingers in the interior of the gear box, according to a further embodiment the first spring retainer can each have at least one nose-shaped projection on two sides opposite to each other, which projection preferably extends in the plane of the spring retainer. The mentioned projections engage positively in corresponding openings formed in the walls of the gear box facing one another, whereby the first spring fingers positively lock onto the walls of the gear box. Thus, no additional fasteners, such as screws, rivets, etc., are required to be able to secure the first spring retainer in the gear box.
The second spring retainer may also have at least one nose-shaped projection on each of the two opposite sides, which projection preferably extends perpendicularly to the plane of the spring retainer. The mentioned projections can engage in corresponding cutouts or slot openings formed in the opposite walls of the gear box, whereby the second spring retainer is movably locked to the walls of the gear box.
According to another aspect of the invention, a lifting slide element and in particular a lifting slide door or a lifting slide window is provided, which lifting slide door or window has a drive gear mechanism according to the aforementioned embodiments.

Detailed Description
Fig. 1 is a schematic view of a lifting slide element 19 according to the invention, which lifting slide element 19 can be moved in a horizontal direction along a rail on the bottom side, not shown here. For this purpose, the lifting slide element 19 has two running carriages 25 on its underside, which running carriages 25 are arranged in the receiving section 21 in the form of a groove which is formed in the underside of the lower frame part 22 of the frame of the lifting slide element 19.
The lifting slide element 19 has a lowered position and a raised position, wherein the lifting slide element 19 is not movable in the lowered position, unlike the raised position. In order to enable the lifting slide element 19 to be transferred between the lowered position and the raised position, the lifting slide element 19 has lifting means, indicated as a whole with the reference numeral "10", by means of which the lifting slide element 19 can be selectively lifted and lowered.
Here, the lifting device 10 mentioned includes: a driving lever 27 located at the side frame part 23 of the elevating slide member 19; two travel elements in the form of two mobile carriages 25 for lifting and lowering the lifting slide element 19; and a transmission gear via which two travel elements in the form of two mobile carriages 25 are coupled with a drive rod 27 with a driving effect. The transmission gear comprises in particular: a first link 26, the first link 26 being coupled with the driving lever 27 via a driving gear mechanism 100 with a driving effect; a second link 29, the second link 29 being coupled with the two mobile carriages 25 with a driving effect; and a deflector 32, the deflector 32 being in the form of a deflection gear mechanism, for example, via which deflector 32 the two links 26, 29 are in turn drivingly coupled to each other in the corner region of the frame of the lifting slide element 19. By deflecting the drive lever 27 according to arrow 28 from its locking position 27 '(in which locking position 27' the lifting slide element 19 is in its lowered position) shown in dashed lines into its unlocking or locking position 27", the lifting slide element 19 can be lifted by the two mobile carriages 25 so that the lifting slide element 19 can be moved along a guide rail, not shown.
The first connecting rod 26 extends here in a receiving section 20 formed as a recess, which receiving section 20 is formed in the side frame part 23 of the lifting slide element, while the second connecting rod 29 extends in a receiving section 21 formed in the underside of the frame of the lifting slide element 19, which receiving section 21 also serves to receive two mobile carriages 25. The two receiving sections 20, 21 (two connecting rods 26, 29 are arranged in the two receiving sections 20, 21) are locked by a first hemming track (stumpchiene) 34 or a second hemming track 36, along which the respective connecting rods 26, 29 are guided movably, however, wherein the second hemming track 36 is not necessarily necessary, since the lower receiving section 21 is not visible.
As can also be seen from the illustration in fig. 1: the fitting arrangement (beschlaganodnung) also has a gas spring 40, which is only schematically shown in fig. 1, which is coupled on the one hand with the first link 26 and on the other hand with the first crimping rail 34. Additionally or alternatively, the accessory device may further comprise a second gas spring 42, which second gas spring 42 is coupled with the second link 29 on the one hand and with the second crimping track 36 on the other hand. The two gas springs 40, 42 are located in the respective receiving section 20, 21 behind the respective crimping rail 34, 36 and the respective connecting rod 26, 29, respectively, and are therefore not visible from the outside.
Since the gas spring 40 or the gas springs 40, 42 are therefore coupled on the one hand to the respective connecting rod 26, 29 and on the other hand to the respective associated bead rail 34, 36 fixedly mounted on the lifting slide element 19, the respective gas spring 40, 42 is increasingly preloaded when the lifting slide element 19 is lowered and increasingly released when the lifting slide element 19 is lifted. Thus, due to the fact that the gas springs 40, 42 are coupled with the respective links 26, 29, the respective gas springs 40, 42 receive and temporarily store at least a portion of the potential energy of the lifting slide element 19 released when the lifting slide element 19 is lowered, so that these potential energies can be given to the lifting slide element 19 when the lifting slide element 19 is subsequently lifted. The respective gas spring 40, 42 is thus loaded when the lifting slide element 19 is lowered, so that an increasing force is exerted on the respective link 26, 29, which force is directed in the opposite direction to the direction of movement of the respective link 26, 29 when lowered. Thus, the holding force to be applied by means of the drive lever 27 is reduced relative to a situation in which the fitting device according to the invention is not used when lowering, so that the risk of the drive lever 27 bouncing upwards in its locked position is reduced.
Conversely, if the drive lever 27 is pivoted downwards from its locking position 27' shown in fig. 1 according to arrow 28 into an open or unlocking position 27″ in order to be able to be lifted via the mobile carriage 25 and thus via the lifting slide element 19, the force required for this is reduced in comparison with a situation in which the accessory device according to the invention is not used, since a part of the weight force of the lifting slide element 19 to be lifted does not have to be applied via the drive lever 27, but is provided as counter force by the gas springs 40, 42. Thus, the energy temporarily present in the gas springs 40, 42 during the lowering of the lifting slide element 19 is released when the lifting slide element 19 is lifted, wherein forces acting in the direction of movement of the respective links 26, 29 are exerted on the links 26, 29, thereby making lifting easier. The lifting of the lifting slide element 19 is thus supported by the gas springs 40, 42, whereby a small force needs to be applied to drive the lever 27. However, since the drive lever 27 first performs an idle stroke when pivoting from its locked position until the movable carriage 25 stands on the guide rail, there is a risk that: the drive lever 27 is pushed against in the direction of the unlocking position of the drive lever 27 by means of driving force reducing means in the form of gas springs 40, 42, whereby tilting is easy to occur.
In order to prevent such tilting of the drive rod 27, according to the invention, a spring catch 120 is integrated in the gear box 106 of the drive gear 100, also referred to herein as the gear housing 106, by means of which spring catch 120 the input shaft 101 can be locked in its locking position 27'.
Fig. 2 shows the drive gear mechanism 100 according to the invention in a position in which the drive lever 27 is in a position corresponding to the locking position 27' of the input shaft 101. The drive rod 27, which is only schematically shown here, has a square shaft 102, which square shaft 102 engages positively with a head 104 of Fang Taotong, which square sleeve head 104 is rotatably mounted in a gear box 106 and forms the input shaft 101 of the drive gear 100.
Two hub sections 118 are formed on the square sleeve head 104, which are axially spaced apart from one another, the hub sections 118 being each formed as an eccentric cam 108 (see in particular fig. 4 and 5), on which eccentric cams 108 a hinge point 112 of a coupling element 110 is hinged, which coupling element 110 establishes a driving-effect connection between an input shaft 110 of the drive gear mechanism 100 in the form of the square sleeve head 104 and a connecting rod 26, which in turn is coupled in a driving-effect manner to the trolley 25 of the lifting slide element 19 in the manner and method described previously. The coupling element 110 is connected to the connecting rod 26 in a hinged manner, for which purpose it hooks into the connecting rod 26 or into a corresponding opening in the connecting rod 26, which allows both longitudinal and transverse forces to be transmitted from the connecting rod 26 to the coupling element 110. The coupling element 110 is thus hooked into the connecting rod 26 in a drop-proof manner, whereby no additional guide has to be provided, by means of which the coupling element 110 can be prevented from being detached from the connecting rod 26 when the coupling element 110 is pivoted about the hinge point 112.
Since the coupling element 110 is thus coupled on the one hand to the connecting rod 26 and on the other hand to the input shaft 101 or the square sleeve head 104, the rotation of the coupling element 110 is converted into a longitudinal movement of the connecting rod 26, which is necessary for the lifting and lowering of the mobile wagon 25, since the coupling element 110 is eccentrically articulated on the square sleeve head 104.
Since the gas springs 40, 42 as the driving force reducing means pre-tighten the link 26 upward, there is a risk that: the connecting rod 26 is connected to the input shaft 101 via a coupling element 110 with a driving effect, and the drive lever 27 is pivoted from its vertically upwardly oriented locking position 27' in the direction of its unlocking position and is thus slightly tilted. In order to counteract this tilting of the drive rod 27, according to the invention, a spring claw 120 is integrated in the gear box 106 of the drive gear 100, by means of which spring claw 120 this tilting can be prevented.
As best seen in fig. 4: the housing box 106 has two housing shells 122 connected to one another, the drive gear mechanism 100 according to the invention comprising its spring fingers 120 being situated between the side walls 124 of the two housing shells, wherein the drive gear mechanism 100 is carried by the housing walls 124.
As can be derived from the overview of fig. 2 to 5: the spring pawl 120 has a fixed or non-movable first spring seat 126 and a second spring seat 128 translatable relative to the first spring seat 126. Furthermore, the spring claw 120 comprises a coil spring 114, which coil spring 114 is tensioned between two spring seats 126, 128, whereby the second spring seat 128 is preloaded against the input shaft 101 and in particular against the eccentric cams 108 of the hub section 118 that are axially spaced apart from one another. The spring 114 is supported here on the first spring retainer 130 and the second spring retainer 132 and surrounds the two guide elements 134, 136, whereby the spring 114 is locked in a drop-proof manner on the spring fingers 120.
The first spring seat 126 has a first spring seat 130 from which a first guide element 134 in the form of a pin extends in the direction of the second spring seat 128. In a corresponding manner, the second spring seat 128 also has a second spring seat 132 from which a second guide element 136 in the form of a hollow cylinder extends in the direction of the first spring seat 126 and accommodates the pin 134, whereby the second spring seat 128 is guided by the first guide element 134 for performing a translational stroke movement.
To secure the first spring seat 126 on the two housing walls 124, the first spring retainer 130 has two nose-shaped projections 138 on opposite sides of each other, respectively, the nose-shaped projections 138 extending in the plane of the first spring retainer (see fig. 5). The projections 138 engage in a positive-locking manner in corresponding openings 140, wherein the corresponding openings 140 are formed in the housing wall 124 (see fig. 4), whereby the first spring seat 126 is firmly fastened to the gear box 106 or to both housing walls 124.
The second spring retainer 130 also has two nose-shaped projections 142 on two mutually opposite sides, respectively, the nose-shaped projections 142 extending perpendicularly to the plane of the second spring retainer 132 (see in particular fig. 5) and engaging in corresponding cutouts 144 or slot openings 144, which cutouts 144 or slot openings 144 are formed in the mutually opposite housing walls 124 (see fig. 4). The second spring seat 128 is thus translatably locked to the housing wall 124 and can thus be preloaded against the eccentric cam 108 of the input shaft 101 due to the pretensioning action of the spring 114.
Although, by means of the two eccentric cams 108, which are formed with flat contact surfaces, and the second spring retainer 132, which is also formed with flat contact surfaces in a corresponding manner, which contact the flat contact surfaces of the eccentric cams 108 in the locking position of the input shaft 101, the input shaft 101 can be held in its locking position 27' by the spring fingers 120.
However, in the embodiment shown here it is proposed that: the spring pawl 120 has a defined engagement element 146 in the form of a needle roller 146, which engagement element 146 engages in a form-fitting manner in a semicircular recess 154 in the locking position 27' of the input shaft 101, which recess 154 is formed on the eccentric cam 108 of the hub section 118 which are axially spaced apart from one another.
The needle rollers 176 are rotatably mounted on the second spring retainer 132, for which purpose the second spring retainer 132 has a nose 150 on its side opposite the second guide element 136, which nose 150 extends perpendicularly to the face of the second spring retainer 132, and which nose 150 forms a recess 148 for rotatably receiving the needle rollers 146, see fig. 3 for this purpose. The nose 150 is formed parallel to the two housing walls 124 and parallel to the two hub sections 118 of the input shaft 101 such that the nose 150 is located between the two hub sections 118.
As can be initially derived from fig. 5: the needle roller 146 protrudes from the nose 150 on both sides in the axial direction, so that the section of the needle roller 146 protruding from the nose 150 can engage in a recess 154, which recess 154 is formed on the underside of the eccentric cam 108, whereby the input shaft 101 is locked in its locking position 27' in the desired manner by the spring pawl 120.
