Field of the Invention The present invention relates to anchoring devices adapted to be driven into the ground for the purpose of providing boundary markings, points of attachment for guy wires and other similar purposes. Accordingly, the general objects of the present invention are to provide novel and improved apparatus of such character.
2. Description of the Prior Art Numerous ground engaging anchor devices are known in the art. One of the more popular previously available devices includes a rod bent helically; the device being driven into the ground by rotation about the longitudinal axis of the helix. An anchor of the helical type is quite difficult to accidentally withdraw from the ground but suffers from the drawback of requiring a comparatively long time to insert in the ground.
Devices easier to install than the previously described helical anchors have been proposed. A number of such devices comprise a rod having, adjacent the end which is driven into the ground, a plurality of outwardly extending studs or vanes. Anchors characterized by vanes may be installed more easily than the devices which have to be rotated but suffer from the disadvantage that the laterally extending parts disturb the ground as the device is driven into the ground and accordingly the devices may be withdrawn with comparative ease.
Anchor devices are also known wherein the main rod portion is provided with pivotal lateral projections in the vicinity of the leading end. These projections are designed to spread outwardly when an attempt is made to withdraw the anchor thereby enhancing the anchor-- ing effect. Devices with the movable projections possess the inherent disadvantages that they are comparatively expensive, when compared to other devices for performing the same function, and after the devices have been installed for a period of time soil tends to clog the joints thereby possibly preventing the spreading'of the projections when the withdrawing force is applied. Additionally, such devices must be extracted a limited distance in order to obtainmaximum retention effect from the movable projections thereby permitting, at the very least, a degree of vertical movement which may be undesirable.
SUMMARY OF THE INVENTION The present invention overcomes the above briefly discussed and other deficiencies and disadvantages of the prior art by providing a novel and improved an-' choring device which is easy to use, economic to produce and which will resist considerable tractive stress without being pulled from the ground. In accomplishing the above objectives the present invention comprises an elongated member having a first end which will be driven into the ground. The elongated member, adjacent its ground penetrating end, is provided with a plurality of lateral vanes which are oriented so as to define acute angles with the axis of the member at the side thereof which terminates in the second end. The'inclined vanes are each provided with a weakened portion which facilitates the bending of the vanes at a point intermediate their length. The second or head end of the elongated member, which is engaged by a suitable tool or object to drive the device into the ground, is further provided with means which enable the member to be engaged by a tool in order to rotate the elongated member about its axis after it has been driven into the ground to the desired depth.
In accordance with a preferred embodiment, the devices of the present invention are driven into the ground by striking the second or upper end with a suitable weighted object. Thereafter the elongated member portion of the devices are engaged by a suitable tool and rotated through an angle of approximately 90. During rotation the inclined vanes will be subjected to considerable strain and will bend about the weakened point intermediate their length. The bending action will result in the upper portions of the vanes spreading out transversely to the axis of the elongated member thereby providing means which will resist considerable tractive stresses attempting to withdraw the device from the ground.
In a preferred embodiment of the invention the weakened part of each of the vanes defines a line which forms an obtuse angle with the axis of that portion of the elongated member located to the second or head end side of the vanes. Accordingly, by providing the vanes with sufficient length, upon rotation the free ends of the vanes will come to rest against the adjacent vanes after the elongated member has been rotated. Accordingly, when a vertical tractive force is applied the vanes will be supported on one another and will be unable to bend any further about the weakened portions. In accordance with the preferred embodiment each vane will be comprised of a flat metal bar with the weakened portion which enables the vanes to be bent over after installation consisting of at least one notch provided along an edgeof each bar.
The elongated member portion of the devices of the present invention may be comprised of the tubular element open at both ends. If such a tubular element is employed the device may be inserted into the ground with the aid of a pointed bar which is inserted through the tubular element and extends beyond the first end thereof. The device is installed by striking the head portion of the pointed bar whereby the pointed end produces a preliminary'or pilot hole which facilitates the penetration of the ground. The use of a tubular elongated member and pointed rod is particularly advantageous when the anchoring devices are to be installed in rocky ground.
- ing a pair of holes located apart. This enables the rotational movement to be imparted to the anchoring device by means of a simple lever which is provided, adjacent one of its ends, with two parallel radial points designed to interact with the holes in the head of the elongated member.
The present invention also encompasses a tool for use in the installation of embodiments of the anchoring devices which are characterized by an elongated member comprised of a tubular element. The installation tool comprises the aforementioned pointed bar which is provided with a detachable coaxial handle at its other or head end. This arrangement permits insertion of the anchoring device into the ground by causing the bar to slide alternately in one direction and then in the other with the point on the bar producing a preliminary hole in the ground on each downward movement while the head, when contacting the upper end of the anchoring device elongated member, pushes the anchoring device vertically downwards. The tool may also include a bent socket adapted as a first end to be engaged by the elongated member and, at its other end, being provided with the two parallel radial points designed to interconnect with the holes in the head of the anchoring device to achieve rotation.
BRIEF DESCRIPTION OF THE DRAWING The present invention may be better understood and its numerous objects and advantages will become apparent to those skilled in the art by reference to the accompanying drawing wherein like reference numerals refer to like elements in the several figures and in which:
FIG. 1 is a perspective view of a first embodiment of the present invention;
FIG. 2 is a perspective view of the anchoring device of FIG. 1 installed in the ground;
FIG. 3 is a partial cross-sectional side elevation view of a second embodiment of the inventiondepicting a tool utilized in the installation of the device; and
FIG. 4 is a perspective view of the embodiment of FIG. 3, FIG. 4 showing the tool by which the device may be rotated after installation in the ground.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first simultaneously to FIGS. 1 and 2, a first embodiment of the invention comprises an elongated rod 1 terminating at one end in a head 2 of square cross-section. The opposite end 3 of rodl is, as shown in FIG. 2, the end which is adapted to be driven into the ground. In the vicinity of end 3 the rod is provided with four vanes 5 which are welded onto the lateral wall of rod 1. Vanes S consist of flat metal bars arranged in such a manner that the angle a which they form with the rod portion to the head side of .their points of attachm'ent will be an acute angle.
Each of vanes 5 is provided, on two opposite edges at a point intermediate its length, with notches 6 which define a zone of reduced resistance c around which the free ends 7 of the vanes can bend. These zones c of reduced resistance define lines which form an obtuse angle b with the portion of rod 1 to the head side of the vanes.
The anchoringdevice of the embodiment of FIGS. 1 and 2 is driven into the ground to the desired depth, which will be commensurate with a point intermediate the length of rod 1, by striking the head 2 with a suitable weighted object. After the device has been inserted in the ground the rod is caused to rotate about its own axis by means of a tool such as wrench 8 fitted with a long handle 9. During rotation, which should be through an angle of approximately 90, the free end portions 7 of the vanes are subjected to greater lateral force than the parts of the vanes which are supported on the rod since the end portions 7 are further away from the axis of rotation and thus have to move over a greater distance. The vanes 5 accordingly tend to bend and, due to the presence of the notches 6, the free ends 7 will be bent over comparatively easily. The bending over of the ends 7 of vanes 5 reduces the force required for rotation of the device and will result in the ends 7 spreading out in a direction which is substantially transverse to the axis of rod 1. By proper positioning of the notches 6 and selection of the length of the vanes 5 the free ends of the vanes 7 will come to rest against the bending zones 0 of the adjacent vanes as shown in FIG. 2. In this position the device will offer considerable resistance to any force tending to pull it out of the ground and the device can be applied to a number of purposes such as, for example, the anchoring of guy wires.
With reference now to FIGS. 3 and 4, an embodiment of the invention particularly well suited for use by surveyors for marking boundaries is shownsThe boundary marker embodiment comprises a tubular member 11 provided'with vanes 12 adjacent its leading end. As in the embodiment of FIGS. 1 and 2, the vanes 12 of FIG. 3 are provided with notches 13 at an intermediate point along their length. The upper end of tubular member 11 is integral with a spherical cap 14 provided with a pair of oppositely disposed holes 15. The boundary marker device is designed to be driven into the ground with the aid ofa bar 16 having a pointed lower end 17. The upper end of bar 16 defines a head 18 which is comparatively heavy and coaxially prolonged by a tenon 19. One end ofa handle member 20 is fitted on tenon 19 and these elements are thereafter assembled by a pin 21 which is passed through aligned holes in tenon 19 and hole. 20. The bar 16 is slightly longer than tubular member 11 and the boundary device may thus be driven into the ground by sliding the bar 16 within member 11 so that the point 17 of bar 16 bores a hole and the head 18, periodically impacting against the upper end of member 11, drives the device downwardly into the pilot hole formed by bar 16.
In order to rotate the boundary device after it has been driven to the desired depth, the tool 22 of FIG. 4 may be employed. Tool 22 comprises a bent sleeve defining a socket at one end which receives the end of bar 16. The bent sleeve is provided with a pair of radial points 23 designed to engage the holes 15 in spherical cap 14 of member 11.
While preferred embodiments have been shown and described various modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way'of illustration and not limitation.
