14 Claims, 9 Drawing Figures MOUNTING MEANS FOR GAS CYLINDERS AND T E LIKE BACKGROUND OF THE INVENTION The present invention relates to an enclosure and a clamping means within the enclosure for securing containers to vehicles such as mobile homes, recreational vehicles and the like. Such vehicles generally have provision for heating, cooking, and the like which utilize containers filled with liquid petroleum, water, compressed air, and the like. These containers are normally fixed to the vehicle at the front portion on the tongue, or at a rear portion or within the vehicle and having an external access opening. Since the containers are so psitioned, it is desirable to place them within an enclosure to protect them from the environment and from damage. In addition, from a purely aesthetic stand point when the container is mounted externally of the vehicle, it is desirable to have such containers enclosed. When so placed within the enclosure, the container must be securely fixed therein to prevent loss or damage, especially to the tubing by which they are connected to inside appliances and which will fatigue and crash under continuous vibration, and in addition to meet certain governmental safety standards with respect to the securement of such containers on vehicles. The containers must be periodically removed for service or replacement; therefore, it is necessary that the securing means should allow removal with ease and without the use of special tools. Yet, at the same time, it is necessary to rigidly restrict the movement of the container within the enclosure during normal use.

Container-retaining means known in the prior art do not meet these requirements. Conventionally, the containers are fixed in place on the vehicle by means of special clamp members and bolted into place, thereby requiring special tools for removal. Spring clamping mechanisms have also been proposed, although they have met with only limited success since the severe environment to which such vehicles may be exposed may shake the container loose from the springs, or may shake the containers so severely as to cause damage. If springs heavy enough to guard against such effects are utilized, special tools are required to relieve the tension on the springs so the container can be removed forservice.

It is therefore an object of this invention to provide a container-retaining means which is not subject to the above described deficiencies.

It is another object of the present invention to provide a combined enclosure and retaining means for the container.

More particularly, it is an object of the invention to provide an enclosure and retainer wherein the container is securely fixed within the enclosure yet releasably secured therein for ease of removal and replacement of the container, without the requirement of any tools.

It is a further object of this invention to provide an enclosure having retaining means therein for one or more containers wherein the retaining means is captively held within the enclosure.

These and other important objects, advantages, and features of the present invention will become readily apparent to those skilled in the art upon reading the following specification and with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and, in particular, to FIGS. 1 and 2, the invention will be described in detail. Basically, the invention includes an enclosure 10 having a plurality of wall members forming a box-like structure opened at the front thereof. The enclosure may be formed of sheet metal or the like and includes a pair of

side walls

12 and 14, a back wall member 16, a top 18, and a bottom 20. The walls are fixed to each other as by welding to form the open front enclosure. A door member 22 (FIG. 1) is hinged at one side of the frontal opening to close the same. Suitable vents or louvers 24 are provided in the face of the door to ventilate the enclosure. A container or cylinder 30 of the type normally utilized for liquid petroleum (LP) gas is positioned within the enclosure and rests on the bottom wall member 20. A pair of spacer blocks 32 are positioned on the

side walls

12 and 14, in the approximate center thereof, to captively hold a retaining means 40, as will be more fully described hereinafter. Basically, the retaining means of the present invention includes an elongated strap 42 preferably formed of spring steel. The strap has an overall effective minimum length which is essentially the same as (or preferably, just slightly shorter than) the circumference of the container, and is provided at the ends with a clamping mechanism 44.

The clamping mechanism includes two basic parts, a generally C-shaped buckle 46 pivotally fixed to one end of the strap 42, and a latch 48 pivotally fixed to the buckle and cooperatively engagable with the opposite end of the strap.

Referring now additionally to FIGS. 3 and 4, the C- shaped buckle 46 is formed of rigid wire stock, preferably cadmium or zinc-plated, and includes a back portion 50, a pair of extending arms 52 and a pair of short inwardly-facing legs 54. The back portion 50 of the buckle is fixed at one end 56 of the strap 42 by rolling pair of the holes 64, such that the latch is pivotally mounted on the buckle legs 54. The openings or holes 64 are provided for adjustment purposes, since the diameter of the container to be fixed within the enclosure may vary somewhat from a nominal standard dimension.

The opposite end of the strap 42 is rolled over or curvedto form a hook 68 which is engageable with an inner end 70 of the latch 48. As best illustrated in FIG. 2, the clamping mechanism is shown in two positions, with the released position being illustrated in phantom lines and the closed or locked position in solid lines. To service a container within the enclosure, the inner end 70 of the latch is positioned within the hook 68'and the latch is pressed toward the container 30 and the strap 42. This pivots the latch about the legs of the buckle, with the strap 42 fitting between the side walls 62 of the latch.'The hook 68,'fitting over the end 70 of j. the latch, moves slightly outwardly from the container asthe la'tch'snaps in toggle fashion into a locking position', -to thereby securely hold the ends of thestrap tightlytogether and about the container. v v g a In the embodiment'of'FIG. 2,-the strap 42 .is securedby means of bolts or machine screws 72 and'lock nuts strapare secured together by the clamping mechanism 44 about a' container, the container is firmly fixed to the walls of the enclosure, and no movement of the container, whether lateral or vertical within the enclosureQwill occur/To remove the container for replace rnen t or refilling, the latch is simply grasped'at'the end oppositethe end engaging the hook 68in the strap and lifted outwardly and away fromthe' container. The two ,endsof the strap may then be separated,'spread apart 'and'the container30 easily removed.

One alternate'holding means for the strap 42 is illustrated in' FIGS. and 6. In this embodiment, a U- shaped channelmember or clip 80 having'a pairof out- 'wardly extending flanges 82 is fixed to the

side walls

12 and 14. The bracket 80 is secured by means of rivets 84 passing through its flanges 82'and through the side walls 12 and I4. Alternately, the bracket may be spot welded or fixed in any other convenient manner to the side walls.

The strap may be fixed directly to the rear wall of the enclosure asshown in FIG. -2, but rather than being fixedly secured to the

side walls

12 and 14, it is simply inserted slidably through the opening formed by the channel member 80, i.e., between the center portion of ments; for the'reasons just stated."

the latter and the side walls. This embodiment has the advantage that as the latch 44 is closed, the steam applied to the strap about the container is evenly distributed along the length of the strap and over the entire surface of the container. In addition, in. the event the strap ever requires replacement, only onescrew 74 need be removed and a new strap slipped into place.

In the embodiment illustrated in FIG/7, the strap 42 is formed for direct connection to the

side walls

12 and 14. In this embodiment, a pair of U-shapedbends are formed along the length of the strap at opposite sides of the enclosure. The bent portions 90 each include a pair of side walls 92 and a bottom wall 94,'ancl cooperatively form a biasing means for extension of the container within the enclosure. An opening is provided in the central portion of the bottom wall 94 through which a rivet 96 or other suitable fastening means is passed to fix the strap to the side walls. In this embodi-' ment, as the ends of the strap are pulled toward one another and connected together by the previouslydescribed toggle-type latching mechanism 44, a slight resilient deformation of the strapside walls 92 may occur as the walls spread outwardly, against the bias of the strap material to embrace the container; There may be, additionally,'a' slight bowingorbending (i.e., oilcanning) of the

side walls

12 and 14 of' the enclosure as the latch mechanism 44 is closed. This bowing of the side walls "is not at all undesirable and in fact serves to even more securely hold the container within thee nclosure; furthermore,- suc hbowing of the enclosure sides may also occur in-any of the other embodiments described above, and is desirable in all'such'embodi- Referring again to FIG. 2, it 'mayjalso be notedthat the sidewalls l2 and 14'taper outwardly with respect to each other from the back 16 of the enclosure toward the frontal opening. This feature isfor convenience in "the manufacturing, storage, and shipping of the enclowithin the other to conserve space until such time as the enclosures are installed on or in a vehicle. I It should not be assumed from the foregoing description that the apparatus of the invention is effective .in

retaining only a single cylinder or' other container member 30. On the contrary, as illustrated in FIGS. 8 and 9, thesame basic apparatusis readily usable in em bodiments'wh'ere two"(or more) cylin'de'rs aojare retained together within an enclosure or 210. In the embodiment'of FIG. 8-, the enclosure 1101a very similar scribed or indicated,: including only a. direct boltor rivet. The embodiment of FIG. 9 is directly comparable, except than-asshown, the enclosure 210 is wider (but not deeper) than'that illustrated in FIGS. 1 and 2, thus permitting a pair of cylinders to be laterally aligned in direct side-by-side relation, with the same basic strap 142 and clamping means 44 being used (the strap 1.42, of course, being longerthan the strap 42 of the earlier figures, but essentially the same in other respects).

From a study of the foregoing description and drawings, it will be readily apparent to those skilled in the art that the present invention provides a simple and extremely effective means for mounting and retaining gas cylinders or like containers, and at the same time provides an enclosure as a part of the retaining means. In addition, the latching mechanism for the retaining apparatus is held within the enclosure and yet is readily releasable, such that the containers may be removed for replacement.

While the invention has been illustrated showing an LP gas container, it will be readily apparent that the concepts taught herein are equally applicable to other types of containers which must be securely fixed in place, and in fact the broader aspects of the inventive concepts are usable either with or without an enclosure. It will be also observed by those skilled in the art that the construction of the enclosure and the number of straps positioned therein may be varied to suit varying sizes and shapes as well as varying numbers and arrangements of containers. A plurality of straps and locking members may be positioned within the enclosure to secure one or more containers at one or more positions, depending upon the size.

While a number of embodiments of the invention have been described, together with minor modifications thereof, it will be recognized by those skilled in the art that other embodiments and modifications incorporating the teachings hereof may be readily made in the light of this disclosure.
