The other end 17b of intermediate arm 17 is connected with the piston shoes that totally are designated 20.In the embodiment shown, piston shoes 20 can be along the vertically moving of second plate 12, and therefore in the embodiment of Fig. 1, can be contained in the leader 19 of second plate 12 and vertically moving along frame side member 2a by slip.But term " piston shoes " should be interpreted as containing and can utilize any combination of the motion that comprises slip, rolling etc. to carry out this mobile any member.
In embodiment shown in Figure 2, leader 19 is the U-shaped with the first shank 19a and second shank 19b basically, and the first shank 19a forms first and second of second shank 19b formation leader 19 of leader 19.The second shank 19b and adjacent part are integrally formed; But other is constructed also can imagine certainly and obtains.Piston shoes 20 are biased, and promptly are subjected to the influence of any device of imposed load on piston shoes.Can provide this biasing by any suitable method.In embodiment shown in Figure 2, this biasing is by spring structure (not shown in this Figure) expression.Under the most frequently used situation, this spring structure comprises a spring or two springs, and as describing in further detail among above-mentioned applicant's European patent No.0 733 146 B1, its content is hereby incorporated by.
As Fig. 3 is more clear illustrate, for clarity sake removed in the drawings second plate and spring the structure, piston shoes 20 comprise check mechanism.Check mechanism comprises coupling mechanism, it comprises by connector 23 two brake members 21 connected to one another and 22, connector 23 extends at a certain angle with respect to each brake member, makes brake member 21,22 and connector 23 can relative to each other present position, a lot of angle.Brake member 21,22 can promptly slide along the first shank 19a and the second shank 19b respectively respectively along the opposite face slip of leader 19.Connector 23 extends towards another brake member 22 from a brake member 21, thereby and the contact surface between the correlation surface of brake member of just discussing and leader forms acute angle, promptly, in the embodiment shown, and the contact surface between the contact surface between the brake shoe 21 and the first shank 19a and/or the brake shoe 22 and the second shank 19b form acute angle.The junction of intermediate arm 17 between a brake member 21 and connector 23 is connected with piston shoes 20, and another brake member 22 is connected with the biasing member of piston shoes 20.For this reason, brake member 22 has hook-type groove 24, and therefore the loading point from biasing member is positioned in groove 24 places.Load is through connector 23, brake member 21 and intermediate arm 17, and the grooves 24 in the brake member 22 are transferred to and recommended arm 14, therefore in the embodiment shown, transfer to sash 1.Each brake member or two brake members all can be provided with the adjustment frictional layer in the face of the respective side on the surface of leader, to reduce the wearing and tearing on brake member and the leader.
Lift apparatus is in being installed to the embodiment of window shown in Figure 1 the time, and its operation is as follows:
The user is from the operating means of make position operation window.This operating means can be the handle (not shown) that is connected with sash bottom 1b, or comprises the assisting in opening device, for example one or more transmission medium cylinder bodies, chain type executor (chain operator) etc.The bias of lift apparatus is on piston shoes 20, and application point is the groove 24 in another brake member 22 as previously mentioned.This load is passed to intermediate arm 17 through connector 23 and a brake member 21, more in turn to recommending arm 14.Recommend arm 14 and apply moment with respect to axis on sash 1, this axis is the hinge axes that is positioned at the window at lift apparatus 10 hinges 13 places in illustrated embodiment.User's applied force of this operating means of binding operation and the moment that therefore produces have overcome the moment that gravity produced of sash 1.In this motion process, piston shoes 20 and move along the leader 19 and the adjacent part 18 of second plate 12 respectively at the intermediate arm 17 and the wheel 16 of recommending junction between the arm 14.In a word, this operation makes sash 1 move on to as shown in Figure 1 open position from make position.
Make the associated components of sash 1 and lift apparatus do reverse motions from the closed window of open position.
In the open and close process of window, the check mechanism that is incorporated in the lift apparatus 10 can be regulated by the power due to the biasing on the piston shoes that act on lift apparatus.
Be the basic principle of explaining that lift apparatus of the present invention contains, with reference to Fig. 4 a and Fig. 4 b, it illustrates the curve that concerns between the spring structure travel distance of a part of relation between expression power and the conventional springs structure travel distance and power and formation lift apparatus of the present invention respectively.
In the structure of the conventional springs shown in Fig. 4 a, power is directly proportional with travel distance, and hysteresis do not occur.That is, the required compressive force of prestrain or bias spring corresponding to discharge because of load or relaxing of spring due to tension force (representing by arrow A and B respectively).
In the effect that occurs in shown in Fig. 4 b in the lift apparatus with piston shoes, these piston shoes comprise the check mechanism of adjusting power.As the conventional springs structure, the prestrain of load and the power in the dispose procedure are directly proportional with the travel distance of spring respectively.But in the load dispose procedure, promptly in the opening procedure such as window, power is with starting from an A ' and terminating in the curvilinear motion of a B '.Its reason is the power that check mechanism has been regulated spring.In the prestrain or biasing process of spring, promptly in the closing course of window, the power that is generated is described as from a B " to A " curve that extends.Therefore, when release and bias spring structure, the curve that is generated is drawn different paths, therefore produces hysteresis.
In the structure that is integrated with lift apparatus of the present invention such as window, this effect make spring structure and check mechanism make a concerted effort to have more cross-domain.The moment with respect to hinge axes due to being made a concerted effort by this is drawn the corresponding curve (not shown) in the open and close process respectively, and this correspondence curve also depends on other factors, for example sash and recommend current angle between the arm.This makes the sash of window can be in stable vent position successively, and for the window in the roof that is installed in different inclination of roof, this vent position is in a lot of open angles.
Hysteresis effect can be carried out optimization according to the requirement of selected mounting condition.Lift apparatus can be made amendment, and makes second plate 12 can be arranged to make first shank of leader 19 and the distance between second shank to increase.This will cause even significant more hysteresis effect.
Obviously, between two shanks of leader be apart from boundary: at two brake members 21 and 22 no longer when the shank of leader is carried out any braking, promptly, at connector 23 no longer between the correlation surface with respect to brake member of just discussing and leader---promptly, in illustrated embodiment, between the brake shoe 21 and the first shank 19a and/or brake shoe 22 and the second shank 19b---contact surface when forming acute angle.
Notice that substitute the distance between the shank that changes leader, the length of connector 23 also can change.
In substituting embodiment shown in Figure 5, have with the embodiment of Fig. 2 and Fig. 3 element identical or similar functions and have identical Reference numeral, just Reference numeral has added 100.Only to being described in detail with respect to the different part of first embodiment.
In the embodiment of lift apparatus shown in Figure 5 110, leader 119 is rod basically.For example, leader or bar 119 can be connected to the second plate (not shown) in the embodiment of Fig. 2 and Fig. 3.A brake member 121 can slide along a side 119a of bar 119, and another brake member 122 can slide along the opposite flank 119b of bar.Therefore side 119a and 119b form the opposite face of bar 119, form leader.Connector 123 extends towards another brake member 122 from a brake member 121, and with a side 119a formation obtuse angle of bar 119, therefore a side 119a constitutes the face that contacts corresponding brake member.In the embodiment of Fig. 2 and Fig. 3, the junction of intermediate arm 117 between a brake member 121 and connector 123 is connected with piston shoes 120, another piston shoes 122 with by 125 schematically the biasing members of sign be connected.
In the above-described embodiment, each brake member that can slide along the opposite face of leader is shown sled shape or the box shaped member that has in the face of the general plane side of leader respective face.In addition, the opposite face of leader is shown parallel to each other and smooth face.
But, can adopt any suitable form that is used for this purpose on the opposite face principle of brake member and leader.Below in the modified example of check mechanism shown in Fig. 6,7,8 and 9.In each of these embodiments, have with Fig. 2 and Fig. 3 embodiment in the element of identical or similar functions of counter element have identical Reference numeral, just Reference numeral has added 200,300,400 and 500 respectively.Only the difference with first embodiment is described in detail.
In the embodiment of Fig. 6, the brake member that piston shoes 220 have roller 221 forms is shown the brake member of box shaped member 222 with another.In the mode corresponding to first embodiment, roller 221 is connected to box shaped member 222 by the connector 223 with respect to the angled extension of each brake member, makes brake member 221,222 and connector 223 relative to each other can present position, a lot of angle.Brake member 221 and 222 can be respectively moves along the opposite face 219a and the 219b of leader 219, that is, can roll in this embodiment and slidably mode move.The junction of intermediate arm 217 between a brake member 221 and connector 223 is connected with piston shoes 220, and another brake member 222 is connected with the biasing member (not shown) of piston shoes 220 through arm 226.Box-like brake member 222 can be provided with the adjustment frictional layer on the side of the face 219b that faces leader 219.
As schematically showing among Fig. 6, first 219a and second 219b draw close towards the right side of figure.This means, under the situation of installment state corresponding to Fig. 1 of lift apparatus, when piston shoes 220 the opening in the motion process when leader 219 moves of sash, the brake member 221 and 222 of check mechanism is forced pressure towards the other side each other.Therefore reduced brake force.This part that can only constitute whole leader of drawing close.This draw close even can be very remarkable, making can not be when leader 219 be further advanced at piston shoes 220, and the motion of sash reaches fully and stops.
In addition, for the precalculated position that much can apply relatively large brake force is provided, one of them of a leader opposite face is provided with a plurality of projections and/or depression.In the embodiment of Fig. 6, this is to be realized by depression 227 in 219 first 219a of leader and projection 228.In the motion process of piston shoes 220, roller 221 is by itself and depression 227 and engaging of projection 228 and temporarily being blocked.When sash was desired to be moved further, the brake member of roller 221 forms must move through projection 228 respectively and 227 shift out from caving in.
First 219a and second 219b can be integrally formed, for example utilize as the leader of the cross section in the embodiment of Fig. 2 and Fig. 3 for U-shaped to form, and therefore this U-shaped narrows down from left to right gradually; But other structure also can be susceptible to certainly.
In another modification shown in the embodiment of Fig. 7, one of them brake member forms box shaped member 321, and another forms roller 322.The opposite face 319a and the 319b of leader 319 form plane and convex surface respectively.This piston shoes 320 along in the motion process of leader 319 for brake force provides variation, so brake force touches the bottom during by the narrowest position at piston shoes 320.Convex surface can have any suitable radius of curvature.Radius of curvature can be constant along the path that piston shoes are advanced or change.
The embodiment of Fig. 8 is the modification of Fig. 5 embodiment, and it demonstrates, and the rod leader 419 of the brake member with a roller 421 and box shaped member 422 forms obviously also can be provided.Moreover rod leader 419 can be provided with projection and/or depression, is provided with a projection 427 in this example.
