' 3 Claims, 8 Drawing Figures COMBINATION TOOL Highway patrolmen and the like are frequently required to attempt to remove injured persons from wrecked vehicles. Quite frequently, the doors of the wrecked vehicle are jammed and are impossible to open in conventional fashion. Additionally, the wrecked vehicle is sometimes lying on its side or top which makes it difficult if not impossible to remove the injured persons therefrom without further injuring them.
Therefore, it is a principal object of this invention to provide a combination tool for opening wrecked vehicles and the like.
A further object of this invention is to provide a combination tool having means thereon for opening the doors of wrecked vehicles.
A further object of this invention is to provide a combination tool having a cutting means thereon which may be used to open the top of the vehicle or which may be used to open the floor board ofa vehicle.
A further object of this invention is to provide a combination toolhaving a chisel means provided thereon.
A further object of this invention is to provide a combination tool comprised of first and second tool members which are slidably connected together, one of the tool members having a hammer head portion thereon which may be used to strike the tool head portion on the other tool member.
A further object of this invention is to provide a combination tool including aflrst tool member which may be slidably struck against a second tool member to enhance the operation of the tool head portion on the second tool member.
A further object of this invention is to provide a combination tool which is economical to manufacture, durable in use and refined in appearance.
These and other objects will be apparent to those skilled in the art.
This invention consists in the construction, arrangements and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in the claims, and illustrated in the accompanying drawings in which:
FIG. 1 is a perspective view of the tool' of this invention in an assembled state.
FIG. 2 is an exploded perspective view of the tool of this invention. i
FIG. 3 is a side view of the tool with portions of the first tool member cut away to more fully illustrate the invention. 2
FIG. 4 is an end view of the tool as seen along lines 44 of FIG. 3.
FIG. 5 is a perspective view illustrating the tool being used to open the vehicle roof.
I FIG. 6 is a perspective view illustrating the tool being used to cut through the metal material of the vehicle roof.
FIG. 7 is a perspective view illustrating the tool being used to open a vehicle door.
FIG. 8 is a perspective view illustrating the tool being used to open a vehicle door. I
The tool of this invention is generally designated by the reference numeral 10 and com prises tool members 1 l2 and 14 which are adapted to be telescopically con- Tool member 14 comprises a bar portion 26 having a I chisel 28 formed at one end thereof. A generally square shaped head portion'30 is welded to the other end of bar portion 26 as seen in the drawings. An arcuate horn-shaped spike means 32 is welded to one face of head portion 30 and extends therefrom in the manner illustrated in FIG. 3. A pry bar means 34 is welded at one end thereof to the outer end of head portion 30 and extends laterally therefrom as illustrated in FIG. 1.
More specifically, pry bar means 34 includes a flat portion 36 and an angularly disposed portion 38 having a sharpened tip 40 at its outer end.
A cutting means 42 is welded to head portion 30 as illustrated in FIG. 3 and includes cutting edges 44 and 46 which are angularly disposed with respect to each other. The numeral 48 refers to the juncture of the cutting edges 44 and 46 and it can be seen thatjuncture 48 is spaced from head portion 30. Cutting means 42 also includes a sharpened point portion 50 at the upper end of cutting edge 44. Head portion 30 is also provid'ed with a striking or tap area .52 adapted to be engaged by the end 20 of pipe section 16 as will be explained hereinafter. v
Preferably, the tool 10 is constructed of a high carbon steel material or the like so as to provide the maximum strength and durability to the tool. The tool can be easily stored in the trunk of a vehicle until such time as it is necessary to use the same. FlGS..5-8 illustrate various ways in which the tool can be usedto open a wrecked vehicle to remove the injured persons therefrom. FIG. 5 illustrates the tool member 14 being used to pierce the roof 56 of a vehicle 58. Bar portion door area by simply striking the hammer head'portion 24 against the flat portion 36 of the pry bar means 34. Force may then be exerted against the tool member 14 to pry open the door. FIG. 8 illustrates a further means of opening the door 60. The tip 40 of the pry bar means 34 is inserted behind the door and the necessary leverage may be applied thereto by simply slidably moving the tool member 12 outwardly with respect to the tool member 14 to achieve the necessary additional I leverage. The tip 40 of the pry bar means 34 may be driven into the area behind the door 60 by utilizing-the hammer head portion 24 on the same.
FIG. 6 illustrates a manner in which the roof of the vehicle may be opened so as to remove persons from the interior of the vehicle. An opening is initially formed in the, roof by striking the roof with the spike means 32 or by driving the point portion 50 of cutting means 42 through the metal roof. Once an opening has i been provided, the point portion 50 is inserted into the opening so that cutting edges 44 and 46 engage the metal roof of the vehicle. The person can grasp the spike means 32 with one hand as seen in FIG. 6 and grasp the hammer head portion 24 in his other hand as also seen in FIG. 6. Tool member 12 can then be slidably moved on tool member 14 in a reciprocal manner so as to cause end of tool member 12 to be driven against the strike area 52 which causes the cutting edges 44 and 46 to cut through the metal roof material. The roof of the vehicle can be opened or removed in a matter of minutes utilizing the tool as seen in FIG. 6 to facilitate the removal of persons from the vehicle through the opening cut in the roof. The cutting means 42 can also be used to cut through the floor board of the vehicle if the wrecked vehicle is resting on its roof.
Thus it can be seen that an extremely unique combination tool has been provided for opening a wrecked vehicle to facilitate the removal of injured persons therefrom. While the tool is ideally suited for such use, it is also well adapted for use by firemen or the like to open doors, etc., of a burning house. Thus it can be seen that the device accomplishes at least all of its stated objectives.
