BARNES ATTORNEYS ANCHOR DEVICE FOR TRAILERS BACKGROUND OF THE INVENTION The present invention relates, in general, to improvements in anchoring devices for trailers, and, more particularly, to a novel arrangement for lashing a mobile home, travel trailer, or the like in a manner to prevent it from being rocked, moved, or otherwise disturbed under severe weather conditions involving high velocity winds.

With the increasing mobility of people in this country, due in part to the proliferation of highways, and in part in increased leisure time, the use of travel trailers and mobile homes has greatly increased. A further increase in the use of mobile homes is due to the rapidly increasing costs of building and owning a home, and many have found it economically advantageous to utilize mobile homes for their permanent residence. A general complaint about such arrangements, however, is that such trailers, being mounted on spring supported axles and wheels, are subject to a considerable amount of rocking and moving about during windy conditions, making these living arrangements somewhat uncomfortable.

Where a mobile home is to be used in a permanent location, some of the foregoing difficulty can be overcome by placing the home on a permanent foundation, but even in such a case, the relatively light weight of these trailers can result in severe damage in a high wind.

Although many trailer parks and camping sites where mobile homes and travel trailers may be parked have provided concrete bases or aprons on which to locate the trailers, in order to level and stabilize the trailer, and while the weight of the trailer is sufficient to permit it to remain in its parking place when blocks are placed around the wheels, such arrangements do not secure the trailer to the ground. Thus, in order to prevent such trailers from being damaged or destroyed by weather conditions, means must be provided to provide a secure anchorage. Various attempts have been made to accomplish this purpose in the prior art; however, these prior devices have been found to be difficult to use and install because of their complexity. Other devices fail to provide the required support, and in order to obtain sufficient stability, must extend a considerable distance from the base of the trailer. These assortments of rods and straps spaced away from the trailer not only are unsightly, but are dangerous, for they generally extend into areas around doors and pathways where people must walk, presenting serious hazards not only to children, but to adults. Further, these arrangements are unsatisfactory because they generally provide only a limited number of contact points between the support members and the trailer, and in severe conditions these contact points can bend the trailer wall, thus loosening the trailer in its anchor, and allowing damaging movement. The rods or bars used in such prior devices then may be brought forcefully into contact with the trailer wall, and the narrow contact area thus presented can permit the bars to cut through the wall, severely damaging the trailer and its contents.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a simple and inexpensive way of protecting and stabilizing parked trailers such as mobile homes or travel trailers from damage due to high winds and other serious weather conditions.

Another object of the invention is to provide an anchor device for a mobile home which permits the trailer to be secured to a concrete base or apron or to other suitable ground anchors.

Another object of the present invention is to provide a mobile home anchor which is unobtrusive, easy to handle and install, and which provides firm lateral support to the trailer while eliminating the hazards of prior devices.

In accordance with the present invention, a trailer anchoring device is provided which consists of a multiple bar support column which in a preferred form consists of three spaced parallel bars in a triangular configuration. The bars are interconnected by suitable braces, or cross members, with the upper and lower ends of the bars being connected to corresponding face plates. In its preferred form, the vertical support column extends from'the ground to the roof level of the trailer, and then extends transversely at least part way across the roof of the trailer. The second similar support column extends up the opposite side of the trailer and across the roof toward the first column, with the upper face plates of the two columns being adjustably connected to each other, as by a turnbuckle arrangement. By fastening the lower face plates of each column to suitable ground anchors adjacent the corresponding sides of the trailer, the support columns may then be drawn up tightly against the trailer by means of the turnbuckle to hold the trailer'firmly in place. One or more such columns may be provided for a trailer, depending upon the size and strength requirements. The columns are covered by a suitable housing to provide a pleasing appearance and a broad surface of contact, and each anchoring device may be installed by means of only three fasteners, one at the bottom of each column, and the interconnecting adjustable fastener at the top.

In another embodiment of the invention, which may supplement or in some cases replace the abovedescribed anchoring devices, a reinforced web is provided as a part of the structure of the trailer. This anchoring device is located within the wall of the trailer, and preferably is secured to the entire upper frame structure of the unit. The ends of the web extends down below the trailer, and are provided with suitable anchor rings for connection to the ground anchors provided in the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and additional objects, features and advantages of the invention will be apparent from the following description, taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a diagrammatic illustration of a mobile home supported by the anchoring devices of the present invention;

FIG. 2 is an end view of the trailer of FIG. 1, illustrating in enlarged detail the multi-bar anchoring device of the present invention;

DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to the drawings, wherein like numerals represent similar parts in each figure, and more particularly to thediagrammatic showing of FIG. 1, the numeral 2 indicates in general a mobile home, travel trailer, or other similar vehicle which is mounted on spring supported wheels and which thus requires an anchoring device to provide stability. The trailer is shown as being parked on a concrete base or apron 4 in which is embedded a plurality of ground anchors 6, 8, '10 and 12 which are adapted to receive the trailer supportdevices, as will be described. These anchors are embedded at preselected locations on" the concrete slab, so that the trailer need only be properly positioned on the slab and the anchoring devices connected to provide the desired stable'and safe securing of the trailer to the ground. It will be apparent that the ground anchors 6, 8, l0 and 12 and the corresponding anchors (not shown) on the other side of the trailer, will be so positioned as to accommodate a particular trailer or the anchors may be so placed as to accommodate a variety of trailer sizes and dimensions. In this latter event, more anchors may be provided than are required for agiven trailer, in which caseit will be desirable to place the anchors in recesses or provide them with ground anchors. Preferably, at least one end of each web is adjustably attached to an anchor so that the trailer may be firmly tied down.

Turning now to FIG. 2, the trailer 2 is shown in an end view, with portions removed in both the vertical and horizontal directions to reduce the size of the illustration, while showing the support columns 16 and 16' in detail. As may be seen from FIGS. 1 and 2, the support column 16 consists of three parallel, spaced, and vertically extending rods or

bars

24, 26 and 28, the three bars forming a column that is generally triangular in cross-section. It will be apparent that by using additional bars, columns of various cross-sectional configurations may be provided, but it has been found that the triangular configuration illustrated anddescribed herein provides the required amountof support and strength.

Bars

26 and 28 are adjacent the wall 29 of the trailer, with bar 24 being spaced therefrom, whereby bars '26 and 28 define a wide surface area for supporting the trailer without damaging it, while bar 24 is spaced therefrom to provide lateral strength to the structure. .In a'preferred embodiment, bar 26 isspaced about 5 inches from. bar 28, thereby providing the width required to prevent damageto the walls of the vehicle. As illustrated in FIG. 2, the column extends fromthe'ground level, where the three bars are connected to a common face plate 30, up along the side of the trailer to the roof edge 32. There, the column is bent or otherwise deformed to extend in a generally horizontal direction transversely of the trailer, across 1 and adjacent to the roof 34. Although the column is shown, it being understood that corresponding columns 16' and 18' are provided on the far side (not shown) of the trailer and meets

columns

16 and 18 at the roof, where they are adjustably connected. The

support columns

16 and 18 are shown with the sheet metal housing removed so as to illustrate the construction of the devices; however, it should be understood that in normal practice the vertical bars and the cross mem-' bers shown in these two columns would be covered so as to provide an attractive and unobtrusive appearance. Preferably, the covering for the support columns would be of the same material from which the outer skin of the trailer is made so that the color and texture would match.

Also illustrated in FIG. 1 are

flexible webs

20 and 22 which may be used in addition to, or in some cases in the. place of the

support columns

16 and 18. These reinforced flexible webs preferably are placed in the trailer during its manufacture so that they are a permanent part of the trailer. These webs extend inside the exterior wall of the trailerand preferably pass up one side, across the roof, and down the other side to provide firm overall support for the trailer, so as to provide a secure support for the trailer. The lower ends of the webs extends out of the trailer body at the exterior walls thereof and carry suitable anchor rings, as will be described, which may be attached to corresponding shown as being bent over at the corner 32, it will be understood that this bend could be made by welding the upper, or horizontally extending, bars at an angle to corresponding vertically extending bars, thereby forming the required angle. It will also be understood that the specific angle between the vertically extending portion of the support column and the generally horizontally extending portion will depend upon the slope of the roof 34, the support column being adapted to follow the contours of the trailer so as to be in contact throughout its length and thereby provide the maximum amount of support.

To provide the required lateral strength for the support column 16, a plurality of braces or cross members 38 are provided between vertical bar 24 and vertical bar 26; similarly, cross braces 40 extend between vertical bar 24 and vertical bar 28. Finally, cross braces 42 are provided between bars 26 and 28 (see FIG. 3) to further strengthen and stabilize the structure. Again,

the number and size of these cross braces will depend upon the strength characteristics required for the column.

In order toimprove the appearance of the support columns,'to provide additional strength, and to provide a wide flat surface of contact between the support column and the trailer wall, the column is encased in a suitable housing or covering 44 which is shown in partial section in FIGS. 2 and 3. As was noted above, this exterior covering or housing 44 preferably is a sheet metal of sufficient thickness to provide an effective continuous surface between the vertical support bars 26 and 28, where the column is in contact with the exterior surface of the trailer. This column surface provides additional support for the trailer walls and eliminates the problems encountered in prior art devices which utilized a single bar that would tend to cut through the outer wall of the trailer. This housing preferably completely encases the column, although it is broken away in FIG. 3 to reveal the structure of the

cross members

38, 40 and 42.

Interposed between the support columns 16 and the side wall 22 and between the column 16 and the roof 34 of the trailer is a flexible resilient pad 46 which may be of rubber, soft plastic, or the like. This resilient pad serves to protect the exterior finish of the trailer, by preventing the support column from directly contacting the trailer wall and roof during assembly of the support columns, during normal use of the anchor device, or under conditions of high wind.

The lower face plate 30, to which the lower ends of the vertical support bars 24, 26 and 28 are fastened, as by welding, provides the means by which the support column may be secured to the ground. As illustrated in FIGS. 2 and 3, the support plate may be generally triangular in shape, and preferably is provided with a centrally located aperture adapted to receive a ground anchor 10. In the embodiment of FIGS. 2 and 3, the ground anchor is shown as being a toggle bolt having a threaded shaft 48 carrying a pair of spreadable arms 50. The toggle bolt may be inserted through the concrete pad 4 in known manner, by drilling a hole therethrough, folding the arms 50 and inserting the assembly through the drilled hole. The arms then open up, and may be drawn up against the bottom of the pad to hold the threaded bolt 48 in position. The upper end of the bolt may then be secured by a nut 52, with bolt 48 extending above the surface of the concrete pad. The face plate may then be placed over the bolt so that the bolt extends through the centrally located aperture, and the plate held in place by a washer 54 and nut 56.

An alternative form of ground anchor is illustrated in FIG. 4, where the threaded bolt 48 is fastened to, or forms a part of a spiral auger 60 which may be twisted into the ground to a depth sufficient to provide the required holding power for the support columns. Again, the bolt 48 extends above the surface of the ground 62 and the face plate 30 is secured thereto by means of a washer and

nut

54 and 56. This arrangement permits the support columns to be used when the trailer is parked in areas not provided with a concrete pad.

Returning to FIG. 2, it will be seen that the anchor device 16 extends transversely over approximately one half of the trailer; a corresponding support column 16' is located on the opposite wall 22' of the trailer and extends up the wall and transversely across the trailer roof toward the first support 16. The two uppermost ends of the support columns are then connected together, as by a turnbuckle 64 which is adjustable so that the two support columns may be drawn together so as to fit snugly against the opposing sides of the trailer and hold the trailer firmly in position. As illustrated, the turnbuckle may conveniently be connected to the

upper face plates

36 and 36 by means of bolts 66 and 68 passing through the centrally located apertures in the corresponding face plates. As is well known, the bolts 66 and 68 are oppositely threaded so that the buckle 70, when rotated, will draw in both bolts and thus draw the face plates toward each other.

Although in the preferred embodiment the support columns 16 and 16' are substantially identical and thus meet at approximately the center of the trailer, it will be apparent that one of the columns can be made sufficiently long to reach completely across the trailer, so that the turnbuckle would be located at one of the corners of the trailer for easier access. Another alternative would provide a continuous support column reaching from the ground on one side of the trailer up the wall of the trailer, across the roof, and down the other side to a point near the ground, with this end of the support member being fastened by means of a turnbuckle to the ground anchor. In any of these alternatives, the support columns form a generally U-shaped support which is adjustably fastened at some point to permit adjustment of the device whereby a tight fit is provided.

As indicated in FIG. 1, a plurality of the anchoring devices formed of the

vertical support columns

16 and 16 may be used for a single trailer, the anchor devices being spaced along the length of the trailer as needed. However, where a trailer is to be moved often, the storage and installation of the support columns may become somewhat inconvenient, and in this event support devices such as the reinforced

webs

20 and 22 may be used. A partial front elevation of such a web is illustrated in FIG. 5, and is shown in cross-section in FIG. 6. The web 20 may take several forms, but in its preferred form comprises a plurality of steel straps illustrated, for example, in FIG. 5 at 80, 82, and 84 connected between two

anchor plates

86 and 88. These steel straps preferably are encased. in a plastic, fabric, or other suitable covering 90 which serves to facilitate the handling of the strap, to hold the bands in the proper relationship, and to protect the trailer from damage by the steel bands. In addition, the covering provides a surface for the web which permits it to be used exteriorly of the trailer, as desired, without marring or damaging the trailer surface.

Although the steel straps may be connected to the anchor plates in numerous ways, a preferred method is to provide loops at each end of each strap, as by folding over the end of the strap on itself and securing it with a clamp 91, the loops passing around a pin 92 in anchor plate 86, and a pin 94 carried by anchor plate 88. These pins pass through corresponding loops formed in the anchor plates, and thereby fasten the straps to the corresponding anchor plates in a hinge-like fashion. The

anchor plates

86 and 88 preferably are provided with

apertures

96 and 98, respectively, which are adapted to receive an anchor bolt or the like so that the ends of the strap may be securely fastened to the ground. Alternatively, one or both of the anchor plates may be fastened to corresponding anchor bolts on opposite sides of the trailer by a turnbuckle or other suitable adjustable fastener so that the straps can be pulled tight to hold the trailer securely in place. Such a turnbuckle may simply thread onto the threaded bolt 48 of the ground anchor, with the opposite end of the turnbuckle carrying a threaded hook-shaped bolt, the hook extending through one of the apertures in the anchor plate, whereby the anchor plate may be pulled down tightly as the turnbuckle is rotated. Other arrangements will be apparent to those skilled in the art.

FIG. 6 is a cross sectional view of the web of FIG. 5, illustrating the manner in which the steel straps 80, 82 and 84 may be embedded in a webbing 90. Various and alternative arrangements may, of course, be used; however, it has been found that the steel strap and the hinge-like connection to the anchor plates provides a most satisfactory arrangement.

As has been explained, the web preferably is ar ranged to pass around three sides of a trailer to form an inverted U-shaped anchor, with the

anchor plates

86 and 88 hanging below the side walls of the trailer on in a given web, and the number of webs provided for a trailerwill be dependent upon the required strength characteristics, and can be varied according to the size and weight of the trailer, its exposure to the weather, and like factors.

Thus, there has been illustrated an improved anchoring device for trailers such as mobile homes, travel trailers, tent trailers and like vehicles, which will firmly hold the vehicle in place even in the face of severe weather conditions. Although specific embodiments of the invention have been shown and described in detail, it will be apparent to those of ordinary skill in the art that numerous changes and modifications in the described arrangements will be possible without departing from the true spirit and scope of the invention as described in the following claims.
