As Fig. 1 to shown in Figure 7, a kind of gliding style bus escape window down, it comprises window frame 11 and forms 13, this window frame 11 comprises left and right sides wall, upper wall and lower wall, simultaneously, the side that this window frame 11 is positioned at car is called inner surface, be positioned at a car side outward is called external surface.This escape window links to each other with the upper edge of forms 13 gliding mass 12 is set, and the chute that matches with gliding mass 12 is set in the two side of window frame 11, and gliding mass 12 moves down synchronously along chute; This escape window also comprises: pushing hands 14, and pushing hands 14 is hinged in the inner surface of forms 13 lower edges, can rotate relative to forms 13 lower edges after pushing hands 14 is stressed; Torsion spring 15, torsion spring 15 connect pushing hands 14 and the forms 13 adjacent with this pushing hands 14 respectively, and pushing hands 14 is subjected to behind the operation torque of torsion spring 15 forms 13 outside opened with certain angle relatively; Block 16, block 16 is fixed in the inboard of window frame 11, and when forms 13 were positioned at closure state, pushing hands 14 linked mutually with block 16; Safety lock 17, when forms 13 were positioned at closure state, safety lock 17 one ends connected pushing hands 14, the other end connects block 16.The pushing hands of this escape window is subjected to moving outside the lower edge of forms after the pushing force of survivor in the car, gliding mass is because the self gravitation downslide like this, simultaneously, the lower edge of forms also moves down after losing and supporting, and finally after pushing hands is opened, form an inclined-plane slide under the effect of support force, in car, move on to ground for the survivor along the inclined-plane slide.
Outwards be offset for the ease of forms 13 relative gliding masses 12, first jointed shaft 19 preferably is set between gliding mass 12 and forms 13, forms 13 rotate around this first jointed shaft 19.Also can adopt other articulated structure, only need guarantee forms and gliding mass when the bus normal operating condition, the sealing of this escape window well gets final product.
Because pushing hands is also rotated relative to forms, so second jointed shaft 20 is set between forms 13 and pushing hands 14, pushing hands 14 is rotated around this second jointed shaft 20, and the relative forms of pushing hands outwards open with final support forms and keep the inclined-plane slide.Torsion spring 15 is two, and it is sheathed on the two ends of second jointed shaft 20 respectively.When forms were in closure state, this torsion spring correspondence was in deformation state, and pushing hands this moment is subjected to the restraint forces of operation torque and the block of torsion spring simultaneously, and restraint forces turns round greater than operation torque, forms is stablized be in closure state.After restraint forces is eliminated, under the powerful pushing force effect that survivor's consciousness of seeking survival produces, when breaking the safety lock safety groove, pushing hands is moved with forms direction outside the vehicle body that hangs down, final under the operation torque and position limiting structure effect of torsion spring, have certain angle between pushing hands and the forms, forms, pushing hands constitute an acute angle shape like this, and promptly forms form an inclined-plane slide.
This escape window comprises and is used to the synchronizing control 18 that guarantees that gliding mass 12 levels move down.Synchronizing control 18 comprises first belt wheel, second belt wheel, first steel wire and second steel wire, first, second belt wheel 181,182 levels are hinged in gliding mass 12 inner surfaces, first, second steel wire 183,184 diagonal angles are fixed in the two side inner surface of window frame 11, simultaneously, this first, second steel wire 183,184 is all walked around first, second belt wheel 181,182.First, second steel wire 183,184 that is paperwrapped in first, second belt wheel 181,182 is 8 fonts.
Pushing hands 14 is L-shaped with the face that links of block 16.
The utility model is no more than preposition in order to guarantee pushing hands 14 when opening, between pushing hands 14 and forms position-limit mechanism is set.Between forms and pushing hands, also limiting section can be set when in addition, forms are opened.
The escape method of this escape window may further comprise the steps: the pushing hands 14 that is hinged in forms 13 lower edges is subjected to external force, departs from window frame 11 until these forms 13 lower edges; Forms 13 continue to depart from window frame 11, and simultaneously, the gliding mass 12 that is positioned at forms 13 upper edges moves down owing to gravity; Gliding mass 12 is displaced downwardly to the lower wall near window frame 11; Forms 13 outwards depart from the inclined-plane slide at the certain inclination angle of final formation, and at this moment, the lateral surface that pushing hands 14 props up the bus vehicle body supports forms 13.
In the process that gliding mass 12 moves down, be hinged in first, second belt wheel 181,182 on the gliding mass 12 and first, second steel wire 183,184 of being fixed on the window frame 11 guarantees that gliding masses 12 move down for level.First, second steel wire 183,184 diagonal angles are fixed in two inside walls of window frame 11, simultaneously, this first, second steel wire 183,184 is all walked around first, second belt wheel 181,182, and first, second steel wire 183,184 that is paperwrapped in first, second belt wheel 181,182 is 8 fonts.
Pushing hands 14 is subjected to the active force that the survivor applies in the car, and this force direction points to outside the car; This active force surpasses the maximum safe holding capacity that connects the safety lock 17 between the block 16 on pushing hands 14 and the window frame 11; After this safety lock 17 was opened, pushing hands 14 was left block 16 back forms and is departed from window frame 11.
Second jointed shaft 20 is set between forms 13 and pushing hands 14, and pushing hands 14 is rotated around this second jointed shaft 20.Torsion spring 15 is two, and it is sheathed on the two ends of second jointed shaft 20 respectively; The lower edge of supporting forms 13 is opened in the operation torque realization pushing hands 14 of torsion spring 15.The angle of inclination of inclined-plane slide is 42～60 °, perhaps directly elects 45 ° as.In order to guarantee to open the angle that back pushing hands and forms remain on setting, preferably between pushing hands and forms, position-limit mechanism is set.

This escape window not only can be opened stressed back automatically, and after opening, does not need I or other people to assist to support forms 13 fully, makes the safe and reliable easily escape of survivor.
The inclination angle design principle of the inclined-plane slide of this escape window is as follows:
The survivor slides to ground by the inclined-plane slide in car, can the inclination angle size of this inclined-plane slide be leaned on by the survivor and slide to ground under the self gravitation and determine, i.e. the inclination angle of inclined-plane slide minimum
Should equal the angle of friction between survivor and the oblique slide
Glide voluntarily on the inclined-plane slide with the guarantor, locking phenomenon do not occur.Friction factor between people and the inclined-plane slide is taken as f=0.9, according to friction and condition of self-locking, and the inclination angle of oblique slide
For:
So the angle of inclination of inclined-plane slide is preferably greater than 42 °, in the time of also can be less than 42 °, this moment, the survivor gets final product along the downward slippage of exerting oneself of inclined-plane slide.When greater than 42 °, consider under the virtual condition survivor can be safely, reliable and glide smoothly, further preferred oblique slide and ground elevation are 45 °.
The survivor is constantly tight in danger, and its pushing force can reach the gravity of human body self, is assumed to be 75kg, i.e. F
1=735N.Because safety lock 17 is made up of a security thread 173 and first, second hold-down bolt 171,172, security thread 173 is pressed between pushing hands 14 and window frame 11 blocks 16 by first, second hold-down bolt 171,172, safety groove 174 structures that its middle part has the cross section to diminish, when the survivor pushes pushing hands 14, during security thread 173 tensions, the small bore place of safety groove 174 produces bigger stress and concentrates, the moment brittle fracture.Break the tensile force f of steel wire through an experimental calculation
2=479 * 735/40=8801N considers that stress is concentrated and to the simulation of actual conditions, dwindles the pushing force several times that steel wire is 740Mpa with the tensile strength of material, the minimum diameter d=1mm that steel wire is broken.
The hands-off design principle of pushing hands 14 motions of this escape window:
Synchronizing control 18 design principles of this escape window:
Because the restriction of forms 13 length and width sizes along moving down direction, can not guarantee that gliding mass 12 glides synchronously.Now adopt first, second steel wire 183,184 of the left and right sides, it be fixed on window frame 11 medial surfaces angie type, respectively be hinged on two belt wheels on the gliding mass 12 and intersect and hold.Regulate the length and the rate of tension of steel wire, when gliding mass 12 glided, two belt wheels moved down synchronously, guaranteed gliding mass 12 parallel downslides.
The principle analysis of this escape window:
Escape window is made up of torsion spring 15 and the safety lock 17 and the position-limit mechanism etc. of 13 of window frame 11, gliding mass 12, forms 13, pushing hands 14, pushing hands 14 and forms.Wherein " safety lock 17 " is made up of the steel wire and the hold-down bolt that are fixed on 14 of window frame 11 and pushing hands, broken as steel wire, and 17 of safety locks are opened, otherwise safety lock 17 is closed.
Under the normal condition, people's pushing force can not be broken safety lock 17 steel wires, and pushing hands 14 is near window frame 11 link stoppers, and is spacing by it, makes forms 13 be in closed condition, and this moment, the angle of torsion that adds in advance of torsion spring 15 was 20 degree, and escape window uses as ordinary window; When on the car emergency taking place, the survivor is when turmoil is crowded, and instinct produces powerful pushing force F
1, produce a tensile force f by fulcrum
2Act on the steel wire of safety lock 17, because stress is concentrated, steel wire is instantaneous to be disconnected from middle part small bore fragility, pushing hands 14 is extrapolated fast with forms 13 along movement locus, forms 13 downslide opening mechanisms quicken downwards to slide under the effect of gravity simultaneously, the distance that gliding mass 12 glides is determined by the limited block on the window frame 11, to slide into for 12 times apart from window frame 11 lower edges be the 17mm place and stop when gliding mass, torsion spring 15 angle of torsion become working torsional angle 90 degree by adding angle of torsion 20 degree in advance, working torsional angle is kept by the position limiting structure between forms 13 and the pushing hands 14, same because the effect of gravity, motion can oppositely not gone up by mechanism, so the former forms 13 instantaneous unlatchings oblique slide at 45 that uses as ordinary window forms a safety, reliable and passway for escaping efficiently.
The application of this escape window is as follows:
I. the survivor is under emergency situation, the crowded pushing force that produces escape outside car by the light of nature, and the forms 13 of will escape are opened, are opened 45 degree and form the inclined-plane slides self-servicely, make the survivor rapidly, safely, reliably, skid off outside the car easily, and do not need other people to assist.
II. utilize gliding mass, realize that deadweight moves down, quicken to open forms 13, formation is particularly suitable for handicapped person, as special survivors' such as old man, child, pregnant woman, baby-holder, individuals with disabilities escape, only need this moment they are put slide, can slide to ground automatically, smoothly.
III. sharply go out the diagonal angle and be connected in two steel wires on the window frame, respectively be hinged on the gliding mass 12 about two belt wheels, intersect and twine, two belt wheels can move down synchronously, guarantee that gliding mass 12 levels glide, and are not stuck in chute.
IV. connect with a security thread 173 between pushing hands 14 and the window frame, just often user's pushing force can not be broken steel wire; The powerful pushing force of survivor when critical is broken security thread from middle small bore fragility, escape window is released fast, and moment opens.
Gliding style is opened automatically under adopting when V. escape window is opened, and compares the escape window of other form, has dwindled the space of opening.
This escape window creatively utilizes deadweight to realize that gliding style is opened escape window automatically down, not only alternative upset, push-and-pull, lift, skylight and smash the escape window of formula, and the various accidents that take place in the suitable more actual life, in very little space, can open quickly and easily;
Ingenious, simple to operate, the excellent performance, with low cost of this escape window design, its series of products are applicable to the safe and quick escape of various crowds on the bus, alternative like product in the market has actual application value.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
