Description

BACKGROUND OF THE INVENTION

This invention relates to an apparatus for use in the installation of floor covering and, more particularly, to an apparatus that can be used for carrying working tools as well as for use as a seaming weight in the installation of floor covering.

It is well known in the flooring industry that a rugged and functional tool box is important. Professional flooring installers, particularly when paid a flat-fee for their work, seek to decrease the time they must spend on the job. Conventional tool boxes used in the flooring industry have only one general purpose, that is, they provide a means for the storage, transportation, and retrieval of numerous tools and miscellaneous items necessary for the installer to properly perform his trade.

Various types of flooring, such as carpet or vinyl, often require separate adjacent pieces of material to be connected along a seam formed along the butting edges of the pieces. It is common for installers to use seaming tape, having hot melt adhesive applied to the upper surface of a backing material along the length of the edges of the flooring material, to join the backing to the floor. A hot iron is moved longitudinally along the length of the seaming tape to melt the adhesive while the backing of the flooring material is pressed down onto the tape with the edges of the flooring material abutting, thereby forming a closely fitted seam as the adhesive cools.

In order to reduce the risk of separation or lifting of the flooring material from the floor, it is important for the flooring material to be properly set while the adhesive cools and dries. Consequently, various weight devices, such as tool box trays, large pieces of wood, metallic weights having handles for manually moving the weight, have been used for compressing the flooring material for a period of time after the flooring has been laid until the adhesive has dried. Such compression has been found to smooth the adhesive and improves the adhesion between the flooring material and the floor.

One problem associated with such weights, such as a seam weight, is that it requires the installer to purchase an extra tool as well as requiring the installer to carry the tool from job to job. Using weighted objects, such as a conventional tool box or tray, is often undesirable because the tool box or trade often has sharp edges which can snag or tear certain types of flooring. Further, such tool boxes and trays are conventionally formed from a metal or a plastic material which can trap heat and is not recommended for use in as a contact surface for a seaming weight and can also leave marks on the flooring due to the color of the tool box or tool tray or due to rusting.

Consequently, a need exists for a tool carrier for storing and transporting the tools of a flooring installer, which is relatively inexpensive, will not snag or discolor the flooring, and which can also be used as a seam weight thereby eliminating the need of an additional tool.

It should be understood, however, that other forms of attachment, such as permanent means such as by glue, rivets, or by other removable means such as by hook and loop means, such as sold by the American Velcro Company under the trademark “VELCRO,” may be used to attach the covering plate 140 to the bottom wall 112 of the tool box 102. Preferably the covering plate 140 is formed from wood, as recommended by the Carpet and Rug Institute having a thickness from about 0.25 in. to about 0.50 in. ( about 0.6 cm to about 1.3 cm), however other materials such as a material selected from the group consisting wood, plastic, glass, paper, or a coated insulated metal which is effective for rapidly dissipating heat may be used. The outer face 146 of the covering plate 140 may also include a layer or coating 141 of an antifriction material such as a wax or polymers of tetrafluoroethylene and copolymers of tetrafluoroethylene and hexafluoropropylene (A commercial embodiment of one such coating is offered by RI DuPont de Nemours under the trademark “TEFLON”).
In a preferred embodiment of the invention, as shown in FIG. 4, the [0046] outer edges 152 of the covering plate 140 are rounded to prevent or reduce the possibility of the covering plate 140 from catching or being snagged by the carpet being seamed, as later described. In another preferred embodiment of the invention, as shown in FIG. 5, the outer edges 152 of the covering plate 140 are rounded and extend over the bottom edge portions of the side walls 106 and 108, front wall 110, and rear wall 114 (FIG. 1) of the tool box 102.
Referring to FIGS. 6 and 7, another preferred embodiment of the invention is shown, wherein the tool carrier and [0047] seam weight 100 includes a tool tray 154 which is adapted to fit within the interior compartment 116 formed withing the tool box 102 and engaging or resting upon an inwardly extending flange or lip 156. As shown, the tool tray 154 is substantially rectangular and includes first and second side walls 158 and 160, respectively, a front wall 162, a rear wall 164 and a bottom wall 166 which define a tray cavity, generally designated 168. The tool tray 154 further includes a pair of substantially triangular flanges 170 which extend from the side walls 158 and 160 away from the bottom wall 166. A handle 172 spans the tray cavity 168 and is suitably attached to the flanges 170, such as by screws, rivets, and the like.
In a preferred embodiment of the invention as shown in FIGS. 8 and 9, the [0048] tool tray 154 is provided with an outer covering plate 176 having an inner face 178 adjacently aligned with the outer face 180 of the bottom wall 166 of the tool tray 154 and a generally flat and smooth outer face 182. Preferably, the covering plate 176 is removably secured in place against the outer face 180 of the bottom wall 166 by a plurality of screws 184 threaded into threaded apertures 186 in the bottom wall 166 of the tool tray 154. It should be understood, however, that other forms of attachment, such as permanent means such as glue, rivets, or by removable means such as hook and loop means, such as sold by the American Velcro Company under the trademark “VELCRO,” may be used to attach the covering plate 176 to the bottom wall 166 of the tool tray 154. Preferably the covering plate 176 is formed from wood having a thickness from about 0.25 in. to about 0.50 in. ( about 0.6 cm to about 1.3 cm), however other materials such as a plastic effective for rapidly dissipating heat may be used. The outer face 182 of the covering plate 176 may also include a layer or a coating 185 of an anti-friction material such as a wax or polymers of tetrafluoroethylene and copolymers of tetrafluoroethylene and hexafluoropropylene (A commercial embodiment of one such coating is offered by RI DuPont de Nemours under the trademark “TEFLON”).
In a preferred embodiment of the invention, as shown in FIG. 8, the [0049] outer edges 188 of the covering plate 176 are rounded to prevent or reduce the possibility of the covering plate 176 from catching or being snagged by the carpet being seamed, as later described. In another preferred embodiment of the invention, as shown in FIG. 9, the outer edges 188 of the covering plate 176 are rounded and extend over the bottom edge portions of the side walls 158 and 160, front wall 162, and rear wall 164 (FIG. 6) of the tool tray 154.
To understand how the parts above described are interrelated, the operation of the tool carrier and [0050] seam weight 100 will now be described. During flooring installation, as shown in FIG. 10, flooring pieces 190, such as carpet pieces, to be joined are laid onto the floor F with the flooring backing 192 facing the floor F. Typically, a strip of tape 194 extends along the abutting edges of the flooring pieces 190 and has a heat-sensitive adhesive 196 or other hot-melt substance, on its side which is contacting the flooring backing 192. A hot iron I is then is then moved longitudinally along the length of the abutting edges 194 of the flooring pieces 190 to melt the adhesive and form a seam S. As the iron I is moved along the abutting edges 194 of the flooring pieces 190, the installer (not shown) moves the tool box 102 of the tool carrier and seam weight 100 having a covering plate 140 such as shown in FIGS. 4 or 5, or the tool tray 154 having a covering plate 176 as shown in FIGS. 7 or 8, along the formed seam S to apply pressure against the seam S to smooth the adhesive 196 and to dissipate heat rapidly away from the formed seam S to ensure better affixation of the flooring pieces 190 to the floor F.
It should now be apparent that the tool carrier and seam weight of the present invention is a cost effective and time effective means of reducing the risk of bubbles or ripples forming along the seam S and the possibility of seam separation. [0051]
It should also now be apparent to those skilled in the art that the use of covering plates reduces the risk of leaving marks, such as rust marks, on the flooring or snagging of the flooring during installation. [0052]
It should also now be apparent that the tool carrier and seam weight of the present invention is effective for applying pressure along the seam to be formed as well as effectively dissipating heat. [0053]
It should also now be apparent that the tool carrier and seam weight of the present invention is not limited to carpet flooring, but can be used for a seam weight for other types of flooring. Further, the tool carrier and seaming weight of the present invention is not limited for use by flooring installers. The use of a smooth, relatively soft covering plate permits easy cleaning thereby reducing or preventing the tool box or tray from marking other surfaces, such as flooring, counter tops, and the like, thus making the tool carrier and seam weight desirable for most professions requiring the use of a tool boxes and the like. [0054]
While the apparatus described constitute preferred embodiments of the invention, it is to be understood that the invention is not limited to the precise apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.[0055]
