THIS INVENTION relates to a hammer assembly particularly adapted to drive tent pegs, or other elongate members made fr~m bent lengths o~ steel or the like, into an operative position in the ground.
ACI(GROUND TO THE INVENTI ON
The driving of a bent spring steel tent peg into a~ operative position in the ground, where a conve~tional hammer is employed, is not an easy operation.. Vnless the bend of the tent peg is struck squarely, the hammer head can tend to slide or slip on the spring steel, and, in so doing, create a dangerous situation or, at least, an uncomfortable one where shock waves are sent up the arm of the person driving the tent peg into position.
It is the object of this invention to provide a tent peg installation device which will obviate the disadvantage described above.

1~?9737 SUMMARY OF THE INVENTION
. .
In accordance with this invention there is provided a tent peg installation device comprising an .
anvil member having a recess therein for accommodating the bend of a bent spring steel type of tent peg, or other bent elongate member, means for releasably closing the recess to releasably retain said bend therein, and a striker head associated with the anvil member, and adapted to co-operate with hammer means for applying a percussive force to the anvil member.
Further features of the invention provide for the hammer means to be attached to the tent peg installation device, for the hammer means to comprise an axially slidable hammer member held captive on a guide rod fixed to the.anvil member; for the anvil member ~o.have-recesses shaped~to accommodate two ox more differently shaped or dimensioned bent portions of tent pegs or the like; and for the guide rod to be positioned with its axis substanl:ially collinear with, in the operative condition, the axis of l:he limb of a tent peg or the like to be percussively driven into position in the ground.

Preferably the anvil member is of a plate-like construction in hnich a ~roove is defined to receive, in relatively snug ~cnner, the bent zane of a tent peg or the .like, in use, and the means for retaining the tent peg in such recess or groove is conveniently a pivotally mounted plate movable in its own plane to selectively cover or expose the groove or recess.
BRIEF DESCRIPTION OF THE DRAWINGS
. . _ In order that the invention may be more fully understood one embodiment of the invention will now be described with reference to the accompanying drawings in whii_h :-FIG. 1 illustrates, in isometric view, a tent __ .
~~: peg installation dev`ice according to the invention; and, FIG. 2 illustrates the device .in an operative _ ~ condition in side elevation.
.
1~29737 DETAILED DESCRIPTION WITH REFEREI~CE TO THE DRAWINGS
In this embodiment of the invention the tentpeg installation device comprises an anvil member 1 carried at one end of a guide roc 2 on which is axially slidable a hammer member 3 which has a central bore receiving the guide rod therethrough.
A stop 4 is provided at the free end of the guide rod to prevent the hammer member from sliding off the rod and t:he hammer member is provided with radially extending operating handles 5 whereby it can be slid up and down the guide rod. The anvil member 1 has, at its end attached to the guide rod, a striker head 6 for co-operation with the hammer member and against which the latter can impinge in use.
~ le anvil member itself is composed of a heavy plate 7 lying in a plane which includes the axis of the guide rod, and, indeed, in use, the axis of a co-operating tent peg indicated by numeral 9.
.
The plate 7 has a first groove 10 therein which passes through a radiused acute angle 11, as illustrated, so as to accommodate a complementarily shaped corner 12 of the tent peg 9.
' ~
~'~Z9737 The groove is arranged such that the axis of the limb 13 of a tent peg to be driven into an operative position is substantially co-axial with the axis of the guid~ rod 2.
Into the samé face of the anvil plate is cut a second groove 14 shaped to conform to the configuration of the hooked end 15 of a tent wall anchor 16. The second groove is arranged such that the shank 17 of the wall anchor will be parallel to the axis of the guide rod but somewhat offset laterally therefrom simply by reason of physical accommodation of the two grooves in the anvil plate.
Pivotally mounted to the face 18 of the anvil plate in which the grooves are cut, is a cover plate 19 arranged to be swung between two positions, one in which it covers the grooves in order to ~aintain any tent peg or wall anchor in operative position in its associated groove (as shown in dotted lines in Fig. 1 and in Fig. 2) or a second position, in which the grooves are open to allow for lateral introduction of the corresponding part of the tent peg or wall anchor (as shown in Fig. 1 in solid lines).
"' . " ' ' ' '' ' . ', ' , .
.
.
9t737 Finally there is proviced on the anvil plate a hook formation 20 at the end thereof remote from the attachment to the guide rod.
In use, for exam~le, for drivins a tent ~eg into an operative position, the tent peg is located in the above described orientation in its appropriate groove in the anvil plate, and the cover plate is moved to a closed position. Lipped lu~s 23 are provided at the edges of the plate to ensure that it is located properly over the grooves. A handle 21 is provided at the free end of the guide rod to facilitate manipulation of the installation device which, with the tent peg in position, is manipulated to orientate the generally horizontal limb 22 of the peg into a roughly horizontal position with the limb 13 to be installed in the ground in an inclined position as illustrated in ~ig. 2.
The hammer member is then slid up and down the guide rod to impart percussive blows to the striker head of the anvil member and, thereby, drive the inclined limb of the tent peg into the g:round.
' ' `, ~ ' .
.
lZZ9'737 Once the tent peg has been driven into its required position, which can be easily achieved in consequence of the construction of the hammer assembly, the cover plate is simply rotated to expose the grooves and the installation device can be moved laterally away from the installed tent peg.
In order to facilitate the removal of a tent peg or wall anchor subsequent to its being required for use, the hook formation can simply be engaged under the bend of the tent peg and percussive blows used in the opposite directlon against an end stop 4 on the free end of the guide rod.
A similar procedure is employed in order to install a wall anchor peg with the hook formation thereof simply being located in its appropriate groove in the anvil plate. A wall anchor can be removed in exactly the same manner as removal of a tent peg with the aid of the hook formation on the anvil plate.
It will be understood that numerous variations may be made to the above described embodiment of the invention without departing from tne scope hereof. In particular, the guide rod and iZ~9~737 g.
.
hammer member need not be made as a perr,anent part of the assembly but could be detacheble therefrom.
Furthermore, a quide rod is not strictly necessary and the scope of the invention is intended to extend to an anvil member with which a separate manually operated hammer is to co-operate in use.
Also, the anvil member could take a number of various diff,erent forms and could, indeed, be composed of a pair of hinged members interconnected by a hinge pin, the axis of which could extend in any required direction in a plane including the axis of the tent peg in usle. A striker head on the anvil would, however, be necessary.
The invention therefore provides an extremely 8imple yet highly effective installation device which can be used for percussively driving any bent steel articles such as spring steel tent pegs, tent wall anchors or other similarly manufactured articles having an elongate shank.
