reference will now be made in detail to the description of the invention as illustrated in the drawings . although the invention will be described in connection with these drawings , there is no intent to limit the invention to the embodiment or embodiments disclosed therein . on the contrary , the intent is to include all alternatives , modifications and equivalents included within the spirit and scope of the invention as defined by the appended claims . fig1 shows a hand powered carpet stretcher 100 that comprises a head 1 having teeth ( not shown ) which engage the carpet and a shaft 2 which is fixed to the head 1 . a lever 3 is pivotally attached to the head 1 by a pin 4 and has a handle 10 . the lever 3 is pivotally connected to a link member 5 by a second pin 6 . the opposite end of the link member 5 is pivotally connected to a base member 7 by a bracket 8 and a third pin 9 . the cylinder member 7 supports the bracket 8 and slidably receives the shaft 2 . a tail block 11 is attached to a short tube 12 by a pin 13 . the short tube 12 can be used to engage additional stretcher tubes 14 between the short tube 12 and the base member 7 in order to lengthen the carpet stretcher . the base member 7 comprises a cylinder member which mates with the stretcher tubes 14 commonly used in carpet stretcher assemblies . the stretcher tubes 14 typically have one male end and one female end such that multiple stretcher tubes 14 can be used together . the number of additional stretcher tubes 14 utilized is dependant upon the size of the carpet to be stretched . the means of assembling them and securing them together are well known in the art . any suitable materials and securing mechanisms may be utilized in the construction of the carpet stretcher . fig2 illustrates the conventional carpet stretcher of fig1 in use , showing the undesirable side - to - side arcing of the stretcher tubes . this arcing reduces the effective carpet stretching force . according to the invention , this problem is overcome by attaching a stabilizer bar as will be described hereinbelow with reference to fig3 , 4 , 5 and 6 . fig3 shows the carpet stretcher 100 of fig1 with a stabilizer bar 15 attached to the top of the carpet stretcher tubes 14 and / or the base member 7 . fig4 shows a perspective view of the underside of the stabilizer bar 15 . in one embodiment , the stabilizer bar 15 consists of a rectangular bar 16 of a light weight and stiff material , such as aluminum or the like . fixedly attached to the bar 16 are a plurality of clips 17 . in operation , the bar 16 with the attached clips 17 are snapped over the top of the stretcher tubes 14 . as the bar 16 is much wider than it is thick , the bar 16 prevents the stretcher tubes 14 from flexing on a horizontal plane with the floor . in an alternative embodiment depicted in fig5 , the top of the stabilizer bar 15 can have a single or a plurality of hinges 18 along the length of the bar 16 in order to accommodate varying numbers of stretcher tubes and for compact storage when not in use . in another embodiment of the invention , shown in fig6 , the flat rectangular bar 16 is replaced with an angular bar 19 . in this embodiment , the clips 17 are also used to attach the stabilizing bar to the carpet stretcher . the angular bar 19 could also be hinged to provide for more compact storage . the angular bar prevents the stretcher tubes from flexing in both a horizontal and vertical plane to the floor . in another embodiment , the stabilizing bar , either rectangular 16 or angular 19 can be permanently affixed to the stretcher tubes 14 in lengths roughly equal to the stretcher tube lengths . thus , as stretcher tubes 14 are added to the carpet stretcher , the stabilizer bars are already attached to prevent flexing of the stretcher tubes 14 .
a carpet stretcher is provided with the improvement of a stabilizing apparatus and method that attaches to a carpet stretching tool to prevent the carpet stretching tool and any of its additional stretcher tubes from bending or bowing when utilized to stretch carpeting during carpet installation . the stabilizing apparatus consists of a bar with appropriate means for attachment to a carpet stretcher .
