[0001] The invention relates to an escape door having automatically disengageable structure.
[0002] Typical doors for house buildings or vehicles comprise a door panel pivotally secured
to a frame. When the panels or the frames are squeezed or jammed, during such as earthquakes,
or traffic accidents, the panels may not be easily opened by the users and thus may
not easily escape from the house buildings or the vehicles.
[0003] The invention to provide an escape door having a panel to be automatically disengaged
from the frame of the house buildings or the vehicles, for allowing the users to be
easily escaped from the house buildings or the vehicles.
FIG. 1 is a plan view of an escape door;
FIGS. 2, 3, 4 are cross sectional views of the escape door;
FIG. 5 is a perspective view of the escape door;
FIG. 6 is a cross sectional view illustrating the operation of the escape door;
FIGS. 7, 8, 9 are partial cross sectional views;
FIG. 10 is an upper view of a vehicle having an escape door;
FIG. 11 is a side view of the vehicle; and
FIG. 12 is a side view of an armored tank.
[0004] Referring to FIGS. 1-6, an escape door comprises a door panel 10 having one side
pivotally secured to a door frame 20 with joints 30, and lockable to the frame 20
with a lock 40. The frame 20 is disposed in a wall 1 and supported on the ground 2.
The panel 10 includes a peripheral portion or four sides (two lateral sides and an
upper side and a lower side) each having an inclined surface 11. The frame 20 also
includes a peripheral portion or four sides (two lateral sides and an upper side and
a lower side) each having an inclined surface 21 engageable with the inclined surface
11 of the panel 10.
[0005] As shown in FIGS. 4-6, when either side forces and/or upper or lower forces are applied
onto the panel 10 and/or the frame 20, the panel 10 may be forced and opened from
the frame 20, such that the users may easily escape from the house buildings. The
inclined surfaces 11, 21 of the panel 10 or the frame 20 may be faced outdoors, for
allowing the panel 10 to be forced out.
[0006] As shown in FIGS. 7-9, the inclined surfaces 11, 21 of the panel 10 or the frame
20 may be flat or curved and arranged for allowing the panel 10 to be forced and opened
from the frame 20 when either side forces and/or upper or lower forces are applied
onto the panel 10 and/or the frame 20. The panel 10 and/or the frame 20 may include
circular, square or various polygonal structure, and may be made of metal, concrete,
plastic or other materials.
[0007] As shown in FIGS. 10-12, an escape door for vehicles 5 or armored tanks 7 also comprises
a door panel 10 pivotally secured to a door frame 20. The panel 10 and the frame 20
each also includes a peripheral portion or four sides (two lateral sides and an upper
side and a lower side) each having an inclined surface 11, 21 engageable with each
other.
[0008] When either side forces and/or upper or lower forces are applied onto the panel 10
and/or the frame 20 of the vehicles 5 or armored tanks 7, the panel 10 may also be
forced and opened from the frame 20, such that the users may easily escape from the
house buildings.
