The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Referring to Fig. 1, Fig. 1 is the structural representation of overboard relief school bag one embodiment of the present invention.In the embodiment shown in Fig. 1, the overboard relief school bag of this structure comprise main bag 20 and with braces 30, and cover the water wings 10 on described main bag 20, front bag 40, subband 31 and aerating device 50.Wherein, described water wings 10 covers on described main bag 20, and is connected with described main bag 20 by some the first junction buttons 60.Therefore, water wings 10 can be by the sack sealing of main bag 20 when usually using.The first junction button 60 is a kind of dismountable jockeys, and water wings 10 both can be arranged on main bag 20, also can some or all of and main bag 20 separation.In addition, apparent, what water wings 10 adopted is airtight at least two which floor structure, and the edge in its outside is connected with main bag 20 by the first junction button 60, and adopts air-locked material to make.In addition, described braces 30 is connected with described water wings 10, and its link position can be according to real experiences setting, and the present invention is not restricted this.
In addition, in the embodiment illustrating shown in Fig. 1, described front bag 40 is positioned at the front of described water wings 10, and is communicated with described water wings 10.In orientation of the present invention term, described " front " and " rear " are to shoulder under state at this school bag, and user's front is described " front ", and user's rear is described " rear ".Therefore, shouldering under state, this front bag 40 is positioned at the position of user's front.Referring to Fig. 3, Fig. 3 is the structural representation of the front bag 40 of overboard relief school bag one embodiment of the present invention.In the embodiment shown in Fig. 3, front bag 40 is communicated with water wings 10, and described front bag 40 is olive-shaped that middle part is wide, two ends are narrow, and its two ends are connected with described braces 30 respectively.Gas in water wings 10 can enter among front bag 40 swimmingly, and front bag 40 is heaved.Referring to Fig. 4, Fig. 4 is the schematic diagram at the front bag 40 A-A place under inflated condition in Fig. 3.The cross section of described front bag 40 is water-drop-shaped, and its area near a side of main bag 20 is less than the side away from described main bag 20.At front bag 40 under inflated condition, the cross section of close the user's of front bag 40 a side is narrower, can embed like this user's neck part, by user's head picking-up, the organ that prevents from exhaling is immersed in the water.In addition on the one hand, in order to increase the buoyancy of front bag 40, the cross section of an other side that front bag 40 is set is wider, the buoyancy of bag 40 before improving.
Because user is under overboard state, the external force of school bag has become buoyancy upwards by downward gravity.In this case, braces 30 is excessive with the closed loop that main bag 20, water wings 10 form, and is difficult to buoyancy to be passed to user, helps user's floating.Therefore,, in the embodiment shown in Fig. 1, can use subband 31.Described subband 31 one end are connected with described water wings 10, and one end is connected with described braces 30 by the second junction button in addition, form a closed loop with described braces 30.When in use, the closed loop that subband 31 and braces 30 form is enclosed in the outside of user's arm, and after user is overboard, subband 31 can be passed to user by the buoyancy of water wings 10 in time, prevents that user from sinking.For easy to use, for example can person easy to use take off school bag or shoulder school bag, subband 31 can be connected with braces 30 by dismountable the second junction button.Shouldering school bag mouth, subband 31 is being connected with braces 30 by the second junction button.In the time of need to putting down school bag, can take the second junction button apart, subband 31 and braces 30 are departed from.
Described aerating device 50, for after user is overboard, is inflated rapidly in water wings 10, and water wings 10 can be kept afloat.Referring to Fig. 2, Fig. 2 is the structural representation of the aerating device 50 of overboard relief school bag one embodiment of the present invention.In the embodiment shown in Fig. 2, aerating device 50 comprises the master controller 52, gas generator 53 and the tactile water sensor 51 that are positioned among described water wings 10, and described tactile water sensor 51 is positioned at the bottom of described main bag 20, and is connected with described master controller 52; Described gas generator 53 is positioned among described water wings 10, and is connected with described master controller 52.In gas generator 53, be provided with the materials such as sodium azide (NaN3) or ammonium nitrate (NH4NO3), master controller 52 sends ignition order, and gas generator 53 is lighted a fire.The reaction of blasting after igniting of material in gas generator 53, can there are rapidly decomposition reactions in these materials, produce a large amount of gas, is full of air bag.Wherein, sodium azide decomposes generation nitrogen and solid-state sodium; Decomposing ammonium nitrate produces a large amount of nitrous oxides (N2O) gas and steam.
Some preferred embodiment in, also comprise the auxiliary bag being attached on described subband 31, described auxiliary bag and described water wings 10 and/or front bag 40 are communicated with, and further improve buoyancy.
Referring to Fig. 5, Fig. 5 is the structural representation of the first junction button 60 of overboard relief school bag one embodiment of the present invention.In the embodiment shown in Fig. 5, described the first junction button 60 comprises the head rod 61 being connected with described water wings 10, and the bottom-hinged of described head rod 61 has some connection pawls 62, and the bottom of described connection pawl 62 is provided with the first crotch portion 621; Also comprise bottom and described main bag 20 the second connecting rods 63 that are connected, the top of described the second connecting rod 63 is the second crotch portion 631 corresponding with described the first crotch portion 621.Wherein, described connection pawl 62 is along the circumferential direction evenly articulated with the bottom of described head rod 61, and described the first junction button 60 also comprises the spring of the upper outside that is enclosed in described the first crotch portion 621.Under connection status, the first crotch portion 621 is connected with the second crotch portion 631, and head rod 61 is connected with the second connecting rod 63.And when the second junction button is under off-state, connect pawl 62 to open, when connecting pawl 62 to the distance of the axis of head rod 61 and increasing, the first crotch portion 621 and the second crotch portion 631 depart from, and head rod 61 and the second connecting rod 63 are separated.
In the embodiment shown in Fig. 5, described the first junction button 60 also comprises the electromagnet 64 being connected with described master controller 52, described electromagnet 64 is near described the first crotch portion 621, can control the first junction button 60 by electromagnet 64 like this, especially can control according to the control signal of master controller 52 state of the first junction button 60.When master controller 52 detects currently during in dewatering state, control the first junction button 60 and open, make main bag 20 and water wings 10 depart from the weight that alleviates school bag.
Some preferred embodiment in, this school bag can also comprise with described master controller 52 and be connected signal generator, described signal generator is positioned among described water wings 10.Wherein, described signal generator comprises one or more in buzzer, flashing light, GPS position indicator and wireless signal transmitter.When master controller 52 detects currently during in overboard state, control signal generator sends control signal and cries for help, and further improves drowning people's the rate of surviving, and ensures student's life security.
Should be appreciated that, the present invention is not limited to above-mentioned embodiment, every various changes of the present invention or modification are not departed to the spirit and scope of the present invention, if these are changed and within modification belongs to claim of the present invention and equivalent technologies scope, the present invention also means and comprises these changes and modification.
