I..'t,;SCIZIPTION AND SPECIFICATIONS for
Eric de Langavant's Boxset I3rams
The Boxset Drams were designed to solve 3 inherent problems that all
serious
drummers face today.
1) The transporiatioa: problem : most conventional drums are voluminous, and
requiY-e
many hands (or trips) to move from one place to another. If one does not have
a car
or a van, one will have to be found, and the drurris usually take up most of
the cargo
space avaiiable. The problem is worse if the drummer wants to take his
instrument on
any kind c;f trip. TN4any drummers have to take their instruments with them on
an
airplane; tae;- traditionally have to pay extra to be able to take the most
essential parts
of their kit, and the drums require special boxes or packing to be secure.
2) The security p.-ol~,lem : There is no way a drummer can leave his
traditional drum set
somewhere (in a club, studio, or pal's house) and be sure that noone will play
with it,
or even steal parts of it.
3) The sound leve". problem : There are many ways a drummer can deaden the
sound of
liis instrumellt : the use of brushes is a traditional way. However, most
traditional
bar drums will still be heard by the neighbours no matter how much damping or
insonorizat;on is used. The lowe: frequencies are very difficult to contain.
Most
serious drumn>:;rs are therefore forced to rent a studio space to practice so
as not to
disturb t,l_e neJbhbors.
The cu=-rent sc3uticnv : Some drum manufacturizlg companies such as Yamaha and
Arbiter iiave tried to remedy the transportation problem'with various formats.
The Yamaha << Hipgig is a complete drumset t~hat fits into a two part ~
(hinged)
conventional bass drum. This is a good sounding conventional drumset, but it
is still
quite voiuminous, it :s not secure (anyone can see that it is a drumset, and
there is nothing
to stop them from touching it), and it is as loud as any other drumsset.
T :-:e 1-,r'citer :< Flat is a drum set that is basically a collection of
skins stretched
on hoops; these drun s have no shell. 'I'his drum set can be packed into its
canvas
carrying bag and transported quite easily. But one cannot leave it unattended
for there is
no way to really lock it (a canvas bag can easily be cut). And the sound is
lacking in the
warmth rhat awood.ein shell will produce.
One solution to the sound level problem has been the emergence of electronic
drara;. Tl.eir volurne can be adjusted ieven cut out) as you would an electric
guitar, but
the sound is dif:erent than tliat of a cog,ventional set and most importantly,
the playing
feel of an electronic drum is very different from that of a conventional
set. Also, the
electronic drum set is not designed for easy transportation., and is even more
vulnerable
to rnis;,andiing.
7'lae t< 13oxset solution : What has been developed by Eric de Langavant is
a
conventional drumset that fits inside a rigid wooden canying box. The carrying
box is an
integral pas-t of the instrument (it serves as the bass drurn's resonance case
when the
instrument is played), and the Box can be locked up securely. It can even be
easily
chained to a wall i-F so desired.

The druin slie;ls used were designed to give the deepest, warmest tones
possible
coi:sidering the sniuls sizes used. The result is a warm, deep sound from very
small
druir.:S ... and tlieir volurne is also reduced. The result is a great
sounding conventional
drum th~~_t i,s suitable for any small to naid-sized roonl. A large room will
require
amplification for tlie bass drum speci ica.lly (there is a trap door in the
bass druni section
to accornodate a microphone).

Specifications of the Iloxset di<arrss : Size - 20 inches x 16 inches x 11
inches;
Weight :,~ lbs. packed. The box consists of two halves that can be locked
shut. The
right half contains the Bass Drum panel, its resonance case, the microphone
trap door,
and storage space for the cymbals, the staare drum and some of the hardware.
*(*box
spurs, torn liolder + s.y nlbal arm). The left half contains the high hat,
storage space for
the 2 tcnis and some of the 1lardware. Every thing has been designed to weigh
the least
pcssisbie, and in such a way that it will all fit inside the box. See Annex 1:
color
pictures oY all an~;tes (Box + hardware), open & closed. Annex 2 : teclmical,
explicative
drav,in,s oi the box and of the hardwax e. (Facultative : Construction of drum
shells :
The shel's are made on 1nolds with2 different types of wood. The 3 inner plys
are
marlogany and the 3 outer plys are maple. The shells are made of only 6 or 7
plys in all,
and are 4 inrn tl:icit (very thin)_
There are 2 bcatures of the Box set that I would like to have in the
patents :
1) the fact that all the druni's components fit into one carry-all wooden box
that also
serves as tl?e bass drurriresonance casu when the instrument is played. aiw 2)
The fact
that rn--st of the hardware has been given a dual function, such as the tom
holders double
as cymbal arnns, and the box spur mounts double as the box's locking
mechanisni.
