TILTABLE DRUMMER'S SEAT
Abstract
A stool having a horizontal plate constrained to a horizontal

Claims
What I claim is as follows:
1. In a stool having a standard supporting a first plate
constrained to a horizontal position, a second plate having
substantially the same conformation as said first plate
superimposed on said first plate, a hinge connecting said first and
second plates at the forward edges thereof, a cushion on said
second plate, said first plate having two spaced threaded holes
therethrough positioned near but spaced from the rearward edge
thereof, elongated screwbolts threadably registering in said holes
and having the upper ends thereof engaging the bottom of said
second plate.
2. In a stool according to claim 1, said cushion having a thickness
which increases progressively in a direction from said rearward
edge of said second plate to said forward edge thereof.
3. In a stool according to claim 2, said cushion being composed of
a plurality of layers including a bottom layer extending across
approximately the forward one-third of said second plate, an
intermediate layer extending across approximately the forward
two-thirds of said second plate and overlapping said bottom layer,
and a top layer surmounting the rearward one-third of said second
plate and all of said intermediate layer.
4. In a stool according to claim 1, said second plate including
spaced buffers on the underside thereof positioned in the paths of
said bolts.
5. In a stool according to claim 4, said buffers having recesses
therein in which the upper ends of said bolts register.
6. In a stool according to claim 5, said cushion having a thickness
which increases progressively in a forward direction.
Description
Besides playing a drum, the drummer in a band actuates various
pedals with his feet. By having his seat tilted in a forward
direction he is not only made more comfortable but he can actuate
the pedals with reduced muscular effort.
Tiltable seats in general are known in the prior art, but they are
complicated structures and their adjustment is attained in a series
of step positions spaced from each other with no provision for
positioning the seat between such stepped positions. The present
invention provides what may be termed an "infinite" number of
tilted positions between the horizontal and the maximum angle of
tilt within the range of the structure. This is desirable since
even minute adjustments in the tilt angle in many cases make a
substantial difference in the feeling of comfort to the individual
drummer.
The invention is illustrated in the accompanying drawing,
wherein:
FIG. 1 is a side elevational view of a drummer's stool showing the
cushioned seat tiled forward at an angle to the horizontal.
FIG. 2 is an enlarged fragmentary rear elevational view of the
stool of FIG. 1, with parts broken away and partly in section.
FIG. 3 is a top plan view of the cushioned seat per se as viewed
along the lines 3-3 of FIG. 1.
FIG. 4 is a fragmentary enlargement of FIG. 1, partly broken away
and partly in section.
FIG. 5 is a sectional view taken on the line 5-5 of FIG. 3.
Referring in detail to the drawing, the numeral 10 designates a
representative type of support for a drummer's swivel seat, which
support includes a member or collar 11 rotatably mounted on the
standard 18 thereof. A horizontal plate 12, hereinafter termed the
fixed plate, is secured to the collar 11. The essential feature
insofar as the present invention is concerned, is merely that the
plate 12 is constrained to a horizontal plane, whether it is itself
solely a seat, as in the usual drummer's stool, or whether it is
part of the combination described below. In other words, the
instant invention may be applied to any common type of drummer's
stool, whether of the swiveling or nonswiveling type.
A substantially similarly shaped plate 13, hereinafter termed the
seat plate, is superimposed on the fixed plate and has its forward
end or edge pivoted to the corresponding end or edge of the fixed
plate by means of a hinge 14. Mounted on the seat plate 13 is a
cushion 15 which may be cemented or otherwise fixed to the
plate.
Spaced equidistantly from the axis of the standard 18 and a
substantial distance from each other near the rear edge of the
fixed plate 12, are a pair of internally threaded holes 16
extending through the plate, and elongated screwbolts 17 which are
preferably metallic and may be of the wing type shown, register
threadably in the holes 16.
As far as now described, it is obvious that the seat plate 13 may
be tilted forward to any desired angle within the range of the
device, by screwing the bolts 17 upward against the seat plate 13.
However, in order to protect the underside of the seat plate from
wear by the tips of the bolts as well as to prevent slippage of the
seat plate and to provide lateral stability thereof, the following
added structure is provided: Secured to the underside of the plate
13 in the paths of the bolts 17, are buffers 19 which may be in the
form of metallic plates and which are provided with recesses 20 in
alignment with the bolts, in which recesses the tips of the bolts
engage. The buffers may, however, be formed integral with the seat
plate, especially if the whole is made of a sturdy plastic
material, and even the bolts may be made of such plastic.
The cushion 15 is preferably built up of layers which may be
cemented together; an example of such a layered structure is shown
in FIG. 5. Preferably the cushion should have a slight constant
slope upward in a forward direction, as shown. The bottom layer 21
is shown extending across approximately the forward one-third of
the seat plate 13, an intermediate layer 22 is shown extending
across approximately the forward two-thirds and overlapping the
layer 21, while a top layer 23 surmounts all. When so built up in
layers, a cover 24 conceals the layers; or a cover, not shown, may
extend around the plate 13 to conceal the latter also.
It is thus apparent that by adjusting both bolts 17 to the same
degree either upward or downward, the angle of tilt of the seat
plate may be altered minutely to attain the most suitable angle for
the individual drummer.
The fixed plate 12 and the seat plate 13 obviously need not have
the noncircular conformation shown in the drawing, for they may
have any desired conformation including circular. In the latter
case the forward edge would be that where the hinge is located.
As to the holes 16 in the plate 12, especially where this plate is
made of wood or plastic, they may be reinforced by an internally
threaded bushing or by a nut imbedded in the plate. Since such an
expedient is common and well known it is believed unnecessary to
illustrate it in the drawing or to describe it in detail.
