861,120 10/1940 France Primary ExaminerAlfred R. Guest Attorney-Charles R. Rutherford [57] ABSTRACT The safety garment structure is designed for use in the construction industry and is adapted to be supported by the shoulders of the body of the wearer. It includes a pair of front and back panels molded or otherwise formed from suitable light weight material, with the panels being hingedly connected at a pair of opposing side edges. The panels when closed on the body surround and protect the chest and the upper part of the body with adequate clearance between the panels and the body to permit lung and abdominal expansion. The panels are provided with opposing arcuate edges to define the neck opening and arm holes and have a configuration generally following the contour of the body?ReleasablTasfening means interconnect the other pair of opposing side edges of the panels to permit the panels to be fastened together on the body. At least one of the panels is provided on the outer surface witha staple-like half-loop or grasp. In the event of an accident, as an example, if a tunnel or trench should collapse, it may be possible to remove the workman by a suitable lifting device which would engage the grasp provided on the safety garment structure and lift the workman to safety.

5 Claims, 2 Drawing Figures SAFETY GARMENT STRUCTURE BACKGROUND OF THE INVENTION 1. Field of the Invention The safety garment structure is particularly suited for use by workers in the construction industry and in particular by persons engaged in the excavation of trenches, tunnels, etc. In the past, even though safety precautions may have been taken by shoring the ground accidents still occur. The shoring or ground collapses trapping the workmen. In the past it has been difficult to remove the injured workmen promptly. The ground and other material must be removed from the area of the trapped workman without injuring him and such removal is normally done manually. The safety garment structure of the present invention protects the upper part of the body from serious injury in the event the workman is trapped by the ground collapsing and in addition a lifting device is adapted to engage the garment structure and help to lift the workman to safety.

2. Description of the Prior Art Various types of garments, vests and armor devices for protecting the body of the wearer are typified by the following U. S. Pats: Webster et al., U. S. Pat. No. 2,517,615, Aug. 8, 1950; Lipshitz, U. S. Pat. No. 2,755,475, July 24, 1956; De Grazia, U. S. Pat No. 2,954,563, Oct. 4, 1960; and Blakeney, U. S. Pat. No. 3,337,875, Aug. 29, 1967.Even though the prior art discloses protective vests or devices adapted to cover the front and back of the wearer, such devices are not suitable for use in the construction industry.

SUMMARY OF THE INVENTION I 'and is substantially concavo-convex in transverse sections so as to follow the contour of the body. The panels are provided with arcuate edges which cooperate to define openings for the neck and for the arms. One pair of opposing side edges of the panels are provided with a hinging device. The other pair of side edges is provided with a releasable fastening device which closes the panels when the structure is mounted on the body.

A feature of the present invention is to provide a safety garment structure made from a material which will suitably withstand the forces exerted by the ground or soil when it collapses around the workman. The safety garment structure must be of a light weight material so as not to unduly interfere with theworkman during the performance of his assigned duties. However, it must be sufficiently rigid and firm in order to withstand the forces exerted by the collapsing ground and to thereby prevent serious injury to the upper part of the bod Abother feature of the present invention is to provide on the outer surface of one or both of the panels a staple-like grasp. In certain types of accidents it may be possible to move a lifting device suchas a crane to the accident site and to engage the hook of the lifting device with the grasp provided on the garment structure and to thereafter lift the workman to safety.

A further feature of the present invention is to provide on the side edges of the panels provided with the releasable fastening device a plurality of fingers on each edge which are spaced apart, the fingers on each panel being adapted to interfit in the spaces between the fingers on the other panel and help to retain the panels together.

Another feature of the present invention is to provide on the generally horizontally extending edges of the panels connecting the neck opening with the arm openings a plurality of fingers which are spaced apart, with the fingers on each panel being adapted to interfit in the spaces between the fingers on the other panel and help to retain the panels together.

Still another feature of the present invention is to provide panels made from a moldable material, each panel containing a plurality of relatively small air ventilation holes.

IN THE DRAWINGS FIGS. 1 and 2 are perspective views of the safety garment structure mounted on a person.

DESCRIPTION OF A PREFERRED EMBODIMENT The safety garment structure illustrated in the drawings is designated by the numeral 10. The structure 10 includes front and

back panels

12 and 14 respectively. The

panels

12 and 14 as illustrated are elongatedfrom top to bottom and each are concavo-convex or slightly curved in transverse sections so as tofollow the contour of the body.

The

panels

12 and 14 are molded from a suitable relatively light weight material such as from aluminum, a magnesium alloy or from one of any number of plastic materials. It is important that the material selected be rigid enough to withstand the forces exerted by the collapsing ground in order to prevent serious injury to th upper part of the body of the workman.

The front panel 12 includes a first arcuate edge 16 for the neck, a pair of second arcuate edges 18 for the arms and a pair of generally horizontally extending edges 20 overlying and adapted to engage the shoulders of the body. The horizontal edges 20 extend between opposite portions of the first edge 16 and the pair of second arcuate. edges 18. The panel 12 is further provided with a pair of vertically extending

side edges

22 and 24 which extend from the second arcuate edges 18 to the bottom of the front panel 12.

The rear or back panel 14 includes a first arcuate edge 26 for the neck, a pair of second arcuate edges 28 for the arms and a pair of generally horizontally extending edges 30 overlying and adapted to engage the shoulders of the body. The horizontal edges 30 extend between opposite portions of the first arcuate edge 26 and the pair of second arcuate edges 28.

The first

arcuate edges

16 and 26 define a neck opening and the cooperating and opposing pairs of second

arcuate edges

18 and 28 define arm openings.

The back panel 14 is further provided with a pair of vertically extending

side edges

32 and 34 which extend from the second arcuate edges 28 to the bottom of the back panel 14.

The opposing longitudinal or

vertical side edges

24 and 34 of the front and

back panels

12 and 14 are arranged opposite one another and are connected by a hinging device or mechanism 36. The hinging mechanism is be in the form of an elongated, vertically and pivotally stable piano type hinge having two

elongated hinge elements

38 and 40 which are provided with interengaging-interfitting pintle-like elements 42 throughout their lengths the interfit inhibiting relative vertical shift of the panels l2, 14. An elongated hinge or pivot pin 44 extends through the pintle like elements 42 to connect

panels

12 and 14 for a controlled stable swing thereof to and from the operative positions of FIGS. 1 and 2. The flanges of the hinging mechanism 36 are secured to the

panels

12 and 14 by conventional fastening methods or devices, not shown.

The opposing longitudinal or

vertical side edges

22 and 32 of the front and

back panels

12 and 14 are arranged opposite one another when the panels are in a closed position as illustrated in the drawing. An appropriate releasable type fastening mechanism 50 secured to

panels

12 and 14 by appropriate means, not shown,

is interposed between side edges 22 and 32 midway between the arm opening and the bottom of the

panels

12 and ,14 as shown in FIG. 1. The fastening mechanism 50 may be opened to permit the

panels

12 and 14 to separate or closed to permit the

panels

12 and 14 to close as shown in the drawing.

The horizontal shoulder edges 20 and of the panels l2 and 14 on each side of the neck opening are each provided with a plurality of elongated fingers, flanges or elements 52 separated by spaces 54. The fingers 52 on one edge interfit in the spaces 54 opposite same in the other opposing edge. The

interfitting finger construction

52, 54 interlock the panels together. The fingers have substantially the same thickness as the panels, are formed when the panels are molded and when interlocked rest upon the shoulders of the wearer.

The opposing side edges 22 and 32 are also provided on each edge with a plurality of elongated fingers, flanges or elements 56 separated by spaces 58. The fingers 56 are arranged in upper and lower sections on opposite sides of the releasable fastening mechanism 50 as shown in FIG. 1. The fingers 56 on one

edge

22, 32 interfit in the spaces 58 opposite same on the opposing edge. The

interfitting finger construction

56, 58 interlock the

panels

12 and 14 and assist the fastening mechanism 50 in maintaining edges '22 and 32 together. The fingers 56 have substantially the same thickness as the panels, are constructed integral with the panels when the panels are molded and when the fingers 56 are interlocked are located at a side of the body of the wearer.

As an optional feature, the

panels

12 and 14 are each provided with a series of perforations or holes 60. The holes 60 are circular in shape and extend completely through the

panels

12 and 14 in order to insure adequate air ventilation or circulation. The use of such holes 60 will not destroy the stability or rigidity of the panels. The

panels

12 and 14 may be partially or entirely perforated.

The front panel 12 and the back panel 14 are each provided with a generally U-shaped staple like halfloop or grasp 62. The grasps are mounted externally. Each grasp 62 is located along the longitudinal center line of the garment structure 10 in the area of the panels intermediate the arm openings. The staple like grasps 62 may be securedto the panels 12 and l4 in any appropriate manner. As an example, the ends of the grasps 62 may be threaded and inserted through the

panels

12 and 14 with washers inserted over the ends of the grasp and retained thereon by means of nuts threaded on the ends of the grasps 62. Other conventional type fastening devices may be used to secure grasps 62 to the panels, as an example welding, staples, etc. It should be understood that one or any number of grasps 62 may be provided on one or both of the panels. The staple like grasp or eyelet 62 must be large enough in order to fit over a hook provided on a conventional lifting device.

The safety body garment 10 when mounted on the user is supported by the shoulders. The body garment 10 fits on the shoulders but leaves the deltoid muscles free for movement. The garment structure 10 fits close to the neck as illustrated in the drawings without restricting the sternocleidomastoid. It will be noted by referring to the drawing that adequate clearance is provided between the panels and the upper part of the body to permit normal lung and abdominal expansion. The panels are curved and follow the contour of the body.
