ATTORNEYS COMBINATION ANCHOR AND SUPPORT UTILIZED TO SECURE A MOBILE HOME TO AN UNDERLYING FOUNDATION SUMMARY OF THE INVENTION This invention relates to a combination anchor and support utilized to secure a mobile home or similar structure to an underlying foundation.

This invention includes a housing having a base and a top wall spaced from the base. The housing base includes means for securing the housing to a foundation underlying the mobile home. The top wall of the housing has an internally threaded opening therein through which an adjustment bolt is threaded. The bolt is generally vertically oriented and includes a head which is located above the housing top wall and which carries a mounting plate. The bolt is provided with means by which it can be rotated within the housing top wall opening so as to cause its longitudinal movement relative to the housing and a resulting variation in spacing between the bolt head and the top wall of the housing. The mounting plate is secured to the head of the bolt by means which permits rotation of the bolt relative to the mounting plate. Suitable anchoring means is provided for attaching the mounting plate to the mobile home.

When locating a mobile home at its home site, it is the preferred practice to provide supports for the home which rest upon an underlying foundation and which permit the wheels of the home to be removed or at least relieved from bearing the weight of the home. Such supports generally constitute concrete blocks which rest upon firm earthen or concrete slab foundations. These blocks may either make direct contact with underlying frame members of the mobile home or, as illustrated in U. S. Pats. NOs. 3,380,205 and 3,022,980, carry adjustable screw means which contact the mobile home frame members. Experience has shown that the concrete block supports have a tendency to shift due to settling of the foundation on which the blocks are set and to deteriorate and crack due to their exposure to the weather. The anchor and support device of this invention can be connected between a concrete support embedded within the ground and the frame of the mobile home in such a manner so as to permit leveling of the home, even after any subsequent settling of ground which carries the concrete support, and to firmly anchor the home against high winds, thus preventing the mobile home from being damaged by ground settlementor by tipping over.

Accordingly, it is an object of this invention to provide a support for a mobile home at its home site which enables the home to be leveled, thus accommodating settling of the underlying foundation for the home.

Another object of this invention is to provide a combination support and anchoring device for a mobile home at its home site which can be secured to the underlying foundation for the home and which serves to anchor the home against high winds during storms and other similar elements of nature.

Still another object of this invention is to provide a combined anchor and support means which is utilized for securing a mobile home to an underlying foundation and which is of economical construction and of simple and easy installation and operation.

Other objects of this invention will become apparent upon a reading of the inventions description.

BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of this invention has been chosen for purposes of illustration and description wherein:

FIG. I is a perspective view of the anchor and support device.

FIG. 2 is a vertical sectional view of the anchor and support device of FIG. 1 shown attached to a channel member of a mobile home frame and anchored to a concrete support embedded in the earthen foundation underlying the mobile home.

FIG. 3 is a fragmentary vertical sectional view of the anchor and support device of FIG. 1 shown attached to an I-beam which constitutes a part of the frame of another type of mobile home.

DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described in order to best explain the principles of the invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.

The illustrated embodiment of the anchor and support device of this invention includes a housing 10 having a cylindrical side wall 12 onto which is welded or similarly secured a base plate 14 and a top wall 16. Top wall 16 of the housing includes a boss 18 which is preferably located on the center axis of the housing. An internally threaded opening 20 is formed in boss 18 and extends through top wall 16. In some constructions of this invention boss 18 may constitute a nut which is positioned over an unthreaded opening formed in a side wall-supported plate and which is welded to the plate. The plate and attached nut will form top wall 16 with the threaded opening of the nut being smaller than and aligned with the unthreaded opening in the plate.

An adjustment bolt 22 is threadedly connected to housing 10 by having its shank 24 turned into opening 20 in top wall 16. Bolt 22 includes an enlarged head 26 which is positioned above top wall 16 of the housing. A generally horizontal mounting plate 28 is carried by bolt head 26. Mounting plate 28 extends across bolt head 26 with the top of the bolt head normally abutting lower face 29 of the plate. A cup-shaped retainer 30 is welded or otherwise secured to lower plate face 29 and encloses bolt head 26 which fits with slight clearance within retainer 30. Shank 24 of the bolt extends with clearance through an opening 31 in the bottom wall of retainer 30. In some constructions of thisinvention, retainer 30 may be U-shaped instead of cup-shaped. A transverse bore 32 extends through shank 24 of the bolt adjacently below retainer 30. Bore 32 is provided so as to enable a rod or similar pivotal means to be inserted through the bolt shank and swung about the axis of the bolt, thus causing rotation of the bolt relative to housing 10 and a raising and lowering of mounting plate 28.

A pair of angle irons 34 is provided to secure the mobile home to mounting plate 28. Referring to FIG. 2, mounting plate 28 is shown attached to a channel member 38 which constitutes a part of the frame of mobile home 36. Angle irons 34 are positioned on 0pposite sides of channel member 38 with the vertical flange parts or legs of the angle irons confronting the sides of the channel member and the horizontal flange parts or legs of the angle irons being secured to the upper face 33 of mounting plate 28 by bolts 40 which extend through registering

apertures

39 and 41 in the angle irons and the mounting plate respectively. One or more bolts 42 extend through registering apertures in the sides of channel member 38 and apertures 44 in the angle irons.

Bolts

40 and 42 are secured in position by suitable nuts 46.

Base plate 14 of housing rests upon a concrete footing or support 48 embedded in soil 50 of the foundation which underlies the mobile home. A plurality of L-bolts 52 or similar anchoring means are embedded within concrete support 48 and have their threaded end portions protruding upwardly through openings 56 in housing base plate 14. Nuts 58 are threaded onto the protruding end portions 54 of bolts 52 and turned down against the upper face of base plate 14 so as to anchor housing 10 to support 48.

There will be two or more, depending on the size and construction of the mobile home, anchor and support devices of this invention spacedly positioned along each side of the home. The pouring of the concrete supports and the subsequent connection of the anchor and support devices between the concrete supports and the mobile home can be accomplished while the home is temporarily supported upon jacks. Once all the anchor and support devices have been attached to the mobile home and anchored to their respective concrete supports, the temporary jacks can be removed with the mobile home load being transferred to the anchor and support devices. By inserting a turning bar through bore 32 in each adjustment bolt 22 and thereafter turning each adjustment bolt, the supported mobile home can be initially leveled and, if necessary, later releveled to accommodate any settling of concrete supports 48. Head 26 of each adjustment bolt 22 fits with sufficient clearance within retainer 30 carried by supported mounting plate 28 so as to permit the head to rotate within the retainer as the adjustment bolt is turned. Additionally, the clearance of bolt head 26 within its retainer 30 also allows for angular movement between the mounting plate and adjustment bolt 22 to prevent binding between the bolt and mounting plate during leveling of the mobile home and to allow for the usual installation of the anchor and support device in which the adjustment bolt will not be located truly vertically.

In FIG. 3, the anchor and support device of FIG. .1 is shown secured to the base flange 59 of an l-beam 60 which constitutes part of another type of a mobile home frame. In securing l-beam 60 to mounting plate 28, base flange 59 of the beam abuts the upper face 33 of the mounting plate with angle irons 34 positioned with their horizontal legs overlying opposite margins of base flange 59 and with their vertical legs extending preferably downwardly and over the side edges of the mounting plate. Bolts 40 extend through registering

apertures

39 and 41 in the angle irons and mounting plate and serve in association with nuts 46 to secure each angle iron to the mounting plate with base flange 59 of the l-beam being clamped therebetween as illustrated.

Each concrete support 48, to which housing 10 of an anchor and support device is attached, may extend a foot or more into the underlying ground foundation depending upon its soil consistency, and, if necessary, can be strengthened by suitable reinforcing rods. The anchor bolts 52 which serve to secure housing 10 to its concrete support should be of sufficient size and embedded sufficiently far into the support so as to prevent the housing from being torn from the support when the mobile home is subjected to high winds.

Leveling of the mobile home is accomplished without detaching the mounting plates 28 of the anchor and support devices from the frame of the home due to relative movement between the mounting plates and bolt heads 26 as the bolts 22 are turned. Thus, the mobile home can be precisely leveled by finite adjustments of bolts 22. Also, in using the anchor and support devices, the concrete supports 48 may be pre-poured at the mobile home site before the mobile home is moved onto the site. The home is then positioned over the concrete supports and the anchor and support devices secured between the home and pre-poured supports.

it is to be understood that the invention is not to be limited to the details herein given but may be modified within the scope of the appended claims.
