ATTORNEYS BATTERING APPARATUS FOR OPENING JAMMED AUTOMOBILE DOORS FlELD OF THE INVENTION BACKGROUND OF THE INVENTION Accident victims frequently die at the scene of the accident because of the inability of rescue workers to quickly remove the victims from the vehicles so that the victims may receive proper medical attention. Since a person can bleed to death in less than a minute, it is readily apparent that the time required to rescue a bleeding accident victim is critical.

Occasionally, the fuel tank of a vehicle involved in an accident will rupture and highly flammable fuel will disperse throughout the accident area. The safety of the accident'victir'ns, as well as that of the rescue workers and innocent bystanders, is further jeopardized by the possible ignition of such fuel and thus it is important that the accident victims should be removed from the vehicle as soon as possible to permit the rescue workers, as well as the victims, to quickly depart the accident area.

Although rescue workers commonly carry pry bars, and the like, for prying open a jammed automobile door so that the vehicle passengers maybe removed, rescue workers find the use of such pry bars physically exhausting as well as time consuming. Accordingly, it is an object of the present invention to provide apparatus for quickly opening a jammed vehicle door.

It is difficult for rescue workers, exerting forces on only the exterior portions of a jammed vehicle door, to pry the door outwardly. It is another object of the present invention'to provide apparatus which will permit a rescue worker positioned on one side of a vehicle to open a jammed vehicle door on the opposite side of I the vehicle by exerting force on the interior surfaces of the jammed door.

Occasionally a rescue worker must work alone/and thus rescue apparatus must be provided to permit a single individual to operate such apparatus. It is also important that such rescue apparatus be constructed so that a rescue worker can quickly, easily, and efficiently apply sharp blows to the jammed door in different locations and in different directions at each location. 7 Other objects and advantages of the present invention will become apparent as the description thereof proceeds.

SUMMARY OF THEINVENTION engageable member swivelably mounted at one end of tion, disposed in operative relation with an automobile,

dinally toward the door so as to exert a sharp blow to the interior of the door tending to move the door outwardly.

The present invention may more readily be described by reference tothe accompanying drawings in which:

FIG. 1 is a sectional side elevational view of apparatus, constructed according to the present invenschematically illustrated in endcross section;

FIG. 2 is a partly exploded, side elevational view of apparatus constructed according to the present invention, parts being broken away for purposes of clarity; and

. FIG. 3 is an end view, taken along the line 34 of FIG. 2, particularly illustrating the fabric engaging plate.

DESCRIPTION OF THE PREFERRED EMBODIMENT Apparatus constructed according to the present invention is particularly adapted for use with an automobile, schematically illustrated at C, having a pair of opposed side doors 10 and 12, each including conventional windows 12a. The interior of each of the doors '10 and'12 is upholstered with fabric material 11, in the normal manner. The door 10 is illustrated as being damaged in such a manner to protrude inwardly a sufficient distance to jam the door 10 and prevent it from being opened in the normal manner.

Apparatus constructed according to the present in-' vention is particularly adapted for opening the jammed car door 10 and includes a pair of telescoping sections,

- generally designated 14 and 16. The section 14 comthe support member, and ram means supported on the other end of the support member for movement in a toand-fro longitudinal path relative thereto to strike a sharp blow to the other end of the support member and drive it, and the upholstery engaging member, longitumember 22, of steel or the like, welded or otherwise suitably fixed to the opposite end 18a of the tubular member 18. The mass member 22 includes a shaft portion 22a, received in the tubular passage 19, which extends through the tube 18, and a head portion 23 having a'slightly enlarged flange 24 in abutting relation with the opposite end 18a of the tube 18 The head 23 is tapered axially inwardly,'in a rearward direction, to assist in guiding the

members

14 and 16 into telescoping relation.

Fixed to the end wall 20 of the support member 18 is a ball shaped member 26 which is received 'in a socket 28 defined by a socket forming member 29 fixed to a denticulated battering plate 30. The denticulated battering plate 30 includes a plurality of pointed, protruding studs, or claws, 32for penetrating the fabric 11 on the interior of the jammed door 10. A handle 34 is fixed to the upper exterior side wall of the tube 18, adjacent the end wall 20, for carrying and supporting the tube 18 while it is being moved to a position in which the studs- 32 engage the fabric 1 l. g

The other telescoping member 16 comprises a ram and includes a tubular member 36 having a passage 37 cident such that the car door is jammed and not openable in the normal manner, a rescue operator passes the

telescoping members

14 and 16 through the window 12a of the opposite side door 12 until the studs 32 penetratingly engage the fabric 11 on the interior of the jammed door 10 so that the end 20 of the support rod 14 is supported thereby. The swivel mount 20, comprising the ball 26 and socket 28, permits the ram portion 16 to be swiveled to the most convenient position, so that the battering force may be applied in any one of a plurality of different directions. The member 16 is manually moved in a reciprocal path designated by the arrow a, from the solid line position shown in FIG. 1 to the chain line position shown in FIG. 1, so that the mass 38 of ram 16 delivers a blow to the mass 23 of support rod 14 to drive the rod 14 and plate 30 toward the door tending to drive it outwardly. The plate 30 can, of course, be moved to another location by merely grasping the handle 34 and moving the studs away from the fabric 11 and repositioning the plate 30 in another location. The mass 38 is repeatedly moved in the reciprocal path to deliver a series of sharp blows to the door until it is opened. The trapped victim can then be removed to a safe location to receive proper medical treatment.

orly upholstered, jammed automobile doors, and the like, which cannot be opened in the normal manner, comprising:

fabric 1 1, the ram 16 extends through the window 12a, of the opposite side door 12, a sufficient distance to permit the ram 16 to be manually grasped and moved in the to-and-fro longitudinal path of travel, designated by the arrow a, into striking engagement with the tubu- S lar member 14.

THE OPERATION When the automobile C has been involved in an ac- It is to be understood that the drawings and descrip- I claim:
