Abstract
A kneeler device for use in applying pressure when making carpet seams includes a rectangular board member formed with a knee receiving curved recess at its forward end and toe ridges at the rear to allow a user to comfortably kneel on the upper surface and advance the member along the seam. The recess may be padded and the toe ridges adjustable.
Description
BACKGROUND OF THE INVENTION
This invention concerns a device useful in carpet laying and more particularly in making seams. Seams are now usually made using a hot glue seaming tape which is positioned beneath adjacent carpet sections to be joined with a heating iron moved along its length to melt adhesive on the upper face of the tape. The carpet sections are pushed together and pressed into the adhesive just behind the heating iron.
Carpet layers often stand on a tool box to exert pressure on the carpet section to insure that the adhesive is pressed into the carpet backing, but this technique is not convenient or particularly effective.
U.S. Pat. No. 4,780,173 issued on Oct. 25, 1988 for a “Carpet Seam Finishing Tool” describes a tool comprised of hinged bodies which are knelt on to exert a bonding pressure on the carpet sections.
However, that device is not any more convenient, comfortable, or efficient to use than the tool box. In fact, that device has the disadvantage of blocking a user's view of the seam, due to its shape at the front which curves under the upper surface on which a user kneels.
A sharp edge on the bottom creates a tendency for glue to mat down the carpet fibers into the glue, making the seam more apparent.
Accordingly, it is the object of the present invention to provide a device for exerting pressure on joined carpet sections which is convenient and comfortable to use, and allows the seaming process to be efficiently carried out.
SUMMARY OF THE INVENTION
This object is achieved by an elongated board-like member having a flat unencumbered bottom enabling pressure to be exerted on a carpet seam under the weight of one leg of the user. The member is of sufficient width to enable kneeling thereon on one leg by a carpet layer. The front end of the member has a curved recess extending across its width terminating in a ridge at the front edge able to be engaged with the top of the user's knee with the knee resting in the recess. The recess is preferably padded to reduce the pressure on the bent knee.
A curved hump blending into the recess may also aid in fitting the member to the user's shin and knee.
The ridge enables the member to be scooted along by a simple leg motion to be easily advanced along the carpet seam without use of the hands.
The front edge of the member is squared off to allow good visibility of the carpet joint as it passes under the flat bottom of the member, allowing the carpet layer to inspect and adjust the joint as necessary.
Toe ridges are also provided to restrain the foot from straightening and to aid the user in hands-free advancing of the member as the carpet layer moves along the seam, and also to engage the toe of his or her shoe to resist any tendency for the foot to straighten and cause cramping.
The lengthwise position toe ridges are preferably adjustable to adapt the device to persons of different size.
Venting holes are preferably formed in the member to assist the venting of steam and to speed cooling of the glue.
A carrying handle may be formed by a crosswise slot at the rear end.

DETAILED DESCRIPTION
In the following detailed description, certain specific terminology will be employed for the sake of clarity and a particular embodiment described in accordance with the requirements of 35 USC 112, but it is to be understood that the same is not intended to be limiting and should not be so construed inasmuch as the invention is capable of taking many forms and variations within the scope of the appended claims.
Referring to the drawings and particularly
FIGS. 1 and 2
, a kneeler device
10
according to the invention comprises an elongated board-like rigid member
12
of generally rectangular shape, having a width so as to readily enable kneeling on the upper surface with the bent knee of one leg at the forward end
14
, and the lower leg and foot extending to the rear and also supported on the upper surface
16
. A width on the order of six or more inches and a length of two feet or longer will enable comfortable use by most persons. The bottom of member
12
is flat and unencumbered to be free of obstructions so as to lie flat on carpet to enable pressure to be exerted across and along a carpet seam by the weight of the user.
A curved recess
18
extends across the width of member
12
at the forward end thereof, leaving a ridge
20
at the leading edge
22
. A padded covering
24
overlies the recess
18
which reduces the pressure felt when the user's weight is supported on one knee positioned atop the covering
24
, the padding compressing sufficiently so that the knee moves partially behind the ridge
20
.
A pair of longitudinally spaced apart toe ridges
26
,
28
extend crossways to the length of the member
12
at the approximate location of the toe of the user's shoe when the knee is positioned in the recess
18
. The toe ridges
26
,
28
are preferably mounted on a slider
30
movable in a lengthwise dovetail slot
32
(
FIG. 2A
) so as to allow adjustment of its location to match the mating of the user. The slider
30
is able to be fixed in any adjusted position as by screws
34
.
The rearmost toe ridge
26
restrains the foot of the user from a tendency to straighten and create discomfort and cramping, while the forward ridge
28
enables the user to scoot the member
12
by hooking of the shoe toe and advancing leg movement. The forward ridge
20
can also be used to an advantage in this maneuver. thus, hands-free advance of the member
12
is conveniently enabled.
A pattern of a plurality of through holes
36
penetrate the member
12
to allow venting of steam to speed cooling of the hot melt adhesive.
In use, the device
10
is placed lengthwise in alignment with a seam to be made between two carpet sections. A heating iron
38
is moved along atop the carpet tape
40
with adjacent sections of carpet above each side of the heating iron
38
in conventional fashion.
The user has the bottom of his or her knee pressed into the recess
18
and the toe of his or her shoe inserted in the space between the toe ridges
26
,
28
.
The pressure applied to the forward end is used to apply pressure with the flat bottom of the member to the carpet edges above the just heated segments of the tap
40
.
The forward edge
22
is squared off to afford a good view of the seam just prior to passing under the member
12
to be pressed into the heated adhesive.
The device
10
is conveniently advanced without use of the hands by leg movement by means of the user's engagement of the toe ridges
26
,
28
and/or forward ridge
20
.
Preferably, a backer board
42
comprised of a thin sheet of plywood is placed below the carpet tape
40
to insure solid application of pressure of the carpet underside to the tape.
The configuration of the kneeler device is such as to result in only minimal pressure on the user's leg to insure allow comfort even during sustained use during the making of carpet seams. The device is also very efficient in affording excellent quality seams to be made quickly with reduced effort in comparison to past practices.
FIG. 3
illustrates variations in the kneeling device
44
which are possible. A carrying handle is created by a crosswise extending slot
46
at the rear edge.
A series of spaced apart fixed toe ridges
48
can be provided rather than the position adjustability described above.
A gently curved hump
50
blends into the forward recess
52
bounded by the forward ridge
54
to comfortably fit the device to the user's knee without padding.
Many other variations are of course possible.
The member
12
can be constructed of various materials, such as finished wood, molded plastic, etc. in the interest of ease of manufacture, as will be appreciated by those skilled in the art.
