1、Air tank bracket with strap-lifting armsBACKGROUND OF THE INVENTIONField of the InventionThis invention relates to the art of brackets and holding devices.More particularly, this invention relates to a bracket for holding afirefighters air tank.In a further and more specific aspect, the instant inve

2、ntion concerns an airtank bracket having means for raising the shoulder straps of the air tank,making it easier for a firefighter to don the tank.Description of the Prior ArtIt is standard procedure to outfit a firefighter or other rescue worker with abreathing apparatus allowing him to breathe norm

3、ally in a smoke-filledbuilding. A typical breathing apparatus consists of a cylindrical air tank orbottle coupled to a face mask, which the firefighter places over his noseand eyes when needed. Shoulder straps, and sometimes a hip harness,are provided on the tank so that the apparatus may be conveni

4、ently carriedon the firefighters back.When not in use, the breathing apparatus is conventionally stored in abracket permanently mounted on a fire truck. The simplest type of bracketconsists merely of a pair of C-shaped clips extending from an elongatedbackplate, with a footplate extending from the l

5、ower end of the backplate tosupport the neck of the air tank. To don the apparatus, the firefighter placeshis back against the air tank and pulls the shoulder straps, which normallyhang limply from the tank, over his shoulders. This is a rather difficultprocedure, especially when the firefighter is

6、clothed in several layers ofheavy, protective clothing, and it can result in a loss of valuable time.Various improvements have been made to conventional air tank bracketsto make it easier for a firefighter to put on an air tank in a shorter period oftime. However, most of the improvements to datehav

7、e centered around making the height or position of the bracketadjustable by, for instance, adding swivels or retraction mechanisms. None,to the best of our knowledge, have addressed the issue of making thetanks shoulder straps easier to slip into.Accordingly, it is an object of the present invention

8、 to provide an improvedair tank bracket with means for raising the straps of the air tank to an easilydonned position.Another object of the invention is a provision of a bracket, according to theforegoing, which is relatively inexpensive to manufacture andcomparatively simple and easy to use.SUMMARY

9、 OF THE INVENTIONBriefly, to achieve the desired objects of the instant invention inaccordance with the preferred embodiment thereof, an air tank bracket isprovided with a pair of pivoting arms for raising the shoulder straps of thetank to a ready-to-wear position.More specifically, the bracket comp

10、rises a pair of resilient, C- shaped clipsprojecting from an elongate, vertically mounted backplate. A footplate forsupporting the neck of an air tank extends from the bottom end of the backplate. A horizontally extending cross bar is secured proximate the upperend of the backplate. An arm, preferab

11、ly of resilient material, is mountedfor pivoting movement at each end of the cross bar. Retaining means, suchas a friction mechanism, are provided to maintain the arms in a raisedposition once they have been lifted. The free end of each arm includes aslit for receiving one of the shoulder straps of

12、the air tank.BRIEF DESCRIPTION OF THE DRAWINGSThe foregoing and further and more specific objects and advantages of theinstant invention will become readily apparent to those skilled in the artfrom the following detailed description of preferred embodiments thereoftaken in conjunction with the drawi

13、ngs in which:FIG. 1 is a perspective view showing an air tank in exploded relationship toa prior art bracket;FIG. 2 is a perspective view showing an air tank mounted in the bracket ofthe present invention;FIG. 3 is a perspective view showing the bracket of the present invention,with the strap-holdin

14、g arms in a raised position;FIG. 4 is a perspective view similar to FIG. 3, showing the strapholdingarms in a lowered position;FIG. 5 is a side view showing a tank mounted in the bracket of the presentinvention, with the strap-holding arms in a raised position;FIG. 6 is a top view of tank and bracke

15、t shown in FIG. 5; andFIG. 7 is an enlarged, exploded fragmentary view showing a retainingmechanism for maintaining the arms of the bracket in a raised position.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTTurning now to the drawings in which like reference characters indicatecorresponding elemen

16、ts throughout the several views, attention is firstdirected to FIG. 1, which shows a prior art mounting bracket 10 and air tank12. The bracket 10 comprises a base member 14, including an elongatebackplate 16 and a footplate 18, and a pair of resilient, C-shaped clips 20,22 which extend outwardly fro

17、m the backplate 16. A pair of auxiliaryfastening straps 24, 26 are also secured to the backplate 16. The basemember 14 is permanently secured to a rigid structure 28, such as the wallof a fire truck.The air tank 12 comprises a cylindrical bottle 30 mounted in a harness 32consisting of a back support

18、 34 and shoulder straps 36, 38. An air mask(not shown) is typically coupled to the neck 39 of the bottle 30. A hipharness and other features could also be included.The tank 12 is mounted neck-down in the bracket 10 with the shoulderstraps 36, 38 facing outwardly. To don the tank 12, a firefighter or

19、 rescueworker puts his back against the harness 32 and threads his arms throughthe shoulder straps 36, 38. However, because the straps 36 are relativelyclose together and hang down loosely, as can be seen in the drawing, thistask is rather cumbersome.The present invention overcomes the foregoing pro

20、blem by providing abracket 40 with means for raising the straps 36, 38 of the tank 12 to aready-to-wear position, as illustrated in FIG. 2.With additional reference to FIGS. 3-6, The bracket 40 comprises a basemember 14 and C-Clips 20, 22 which are similar to their counterparts in theprior art brack

21、et 10, except that a horizontally extending cross-bar 42 hasbeen added at the top end of the backplate 16. A pair of arms 44, 46 isprovided at opposite ends of the crossbar 42. The arms 44, 46 aremounted for pivoting movement from a lowered position generally parallelto the base member 14, as seen i

22、n FIG. 4, to a raised position generallyperpendicular to the base member 14, as seen in FIG. 3. The free end ofeach arm 44, 46 includes a slit 48 for receiving one of the shoulder straps36, 38. The arms 44, 46 are preferably made of a resilient material such asspring steel, rubber or plastic, which

23、allows them to be flexed inwardly forcompact storage when not in use.Other grasping means, such as VELCRO loops, could be provided at thefree end of the arms 44, 46, in lieu of the slit 48.Alternatively, compression springs could be placed at the ends of the arms,with the straps clamped between adja

24、cent coils of the springs.FIG. 7 shows a retaining, or braking, mechanism 50 for maintaining thearms in the raised position after they have been lifted. A pair of friction pads52, 54 are interposed between an ear 56 at each end of the cross-bar 42and the adjacent end of each arm 44, 46. The assembly is held together bya nut 58 and bolt 60. The frictional forces between the pads 52 and 54 aregreat enough to prevent either arm 44, 46 from rotating around the b
