Claims
What is claimed is:
1. A demountable archery bow to be fitted with a bow string,
comprising a handle and limbs having rear sides along which the
string extends and having front sides facing the target, one of the
limbs being separate from the end of said handle,
said end of the handle having a recess opening forwardly and
endwise and removably receiving the end of the limb therein, the
handle having front and rear abutment surfaces at the front and
rear sides of the recess against which the front and rear sides of
the limb bear, the limb bearing against said abutment surfaces with
substantial pressure as the limbs are flexed rearwardly for
stringing the bow and as the bow is drawn and released for casting
an arrow to maintain a rigid relationship between the handle and
limbs, the front abutment surface extending along and confronting
only the inner end of the recess to permit the limb to tilt
forwardly out of the recess for removal, and
latching means on the limb and handle and including a cooperating
insert and socket spring pressed together transversely of the limb
and restraining the limb and handle against endwise separation, the
insert and socket being separable upon manually tilting the limb
forwardly to permit the limb to be withdrawn from the handle, the
insert and socket being located beyond the outer end of the
abutment surfaces of the handle and being spaced along the limb
from the end thereof to permit the limb and handle to fully and
firmly bear against each other at said abutment surfaces.
2. The demountable archery bow according to claim 1 and including a
leaf spring on the handle and lying along the front side of the
limb adjacent the recess, the leaf spring having a free end
adjacent the insert and socket and bearing against the limb to
restrain said limb against forward tilting.
3. A demountable archery bow to be fitted with a bowstring,
comprising a handle and limbs having rear sides along which the
string extends and also having front sides facing the target, one
of the limbs being separate from the handle,
one end of the handle having a rigid bracket affixed thereto, the
bracket having sideplates lying flush against the sides of the
handle and having a rigid strap extending across the front of the
handle, said sideplates extending beyond the end of the handle and
having a rigid pin extending therebetween and spaced rearwardly
from the front of the handle.
Description
BRIEF SUMMARY OF THE INVENTION
Demountable archery bows in the past have had complicated latching
arrangements which have been cumbersome and have had various
protuberances and mechanical devices which made such release
devices quite undesirable for reasons of difficult operation and
because such mechanisms would get caught on branches and leaves
when hunting and would also be damaged and rendered inoperative.
The present invention provides for the simple and efficient
demounting of the limbs of a bow from the handle by providing a
simple socket into which the end of the limb is extended and a
latching device comprising a socket on the limb and an insert or
projection on the handle which restrains the limb against endwise
retraction from the handle. A leaf spring urges the insert and
socket together under normal circumstances, but the limb can be
tilted against the spring for ready and easy removal from the
handle. When the bow is strung up for shooting and when the bow is
subsequently drawn for casting an arrow, the limb and handle are
secured very tightly together without regard to the latching
mechanism so that the limbs are essentially rigid with the handle
and the demountable aspect of the bow has no undesirable shooting
features.

DETAILED DESCRIPTION OF THE INVENTION
One form of the invention is shown in the drawings and is described
herein.
The demountable archery bow is indicated in general by numeral 10
and has a handle 11 and limbs 12, both of which are demountable
from the handle 11. The coupling construction 13 at the joint
between each of the limbs 12 and the handle are identical for each
of the limbs and only one of these will be described.
In FIG. 1, the bow is illustrated in strung condition so that an
arrow may be applied to the string 14 and laid on the arrow rest of
the handle so that the bow may be drawn and then released to cast
the arrow toward the target. It will be recognized that the front
sides 12a of the limbs 12 and the front side 11a of the handle face
the target; and the string 14 lies against or confronts the rear
sides 12b of the limbs 12 and confronts the rear side 11b of the
handle.
As illustrated in FIG. 2, the end of the handle 11 has an elongate
recess 15 extending endwise or longitudinally and also opening
forwardly for receiving the inner end 16 of the limb 12. A rigid
steel bracket 17 is affixed as by screws 17a to the wood base 11.1
of the handle, and the bracket 17 has opposite side panels 17.1 and
17.2 which define the opposite sides of the recess 15. The bracket
17 has a front strap portion 17.3 which extends across the front of
the wood base 11.1 of the handle and defines the front side of the
recess 15, extending a short distance upwardly from the bottom of
the recess 15. The strap 17.3 which defines the front wall of the
recess retains the front side of the lower end 16 of the limb 12
while the rear side of the limb bears against the rear abutment
surface 11.2 which defines the rear side of the recess 15.
Above the strap 17.3, the front side of recess 15 is substantially
open to permit the limb 12 to tip forwaRdly in the direction of
arrow A when the limb is relaxed and the bow is unstrung or let
down. However, forward tipping of the limb 12 in the direction of
arrow A is restrained by an elongate leaf spring 18 which is
affixed as by welding or brazing at its lower end to the rigid
cross strap 17.3.
The handle 11 is provided with a rigid cross pin 19 which is
affixed as by welding to the opposite sideplates 17.1 and 17.2 of
the bracket 17 at a position opposite the upper end of the leaf
spring 18. At this same location, the limb 12 is shaped to define a
pin-receiving socket 20 so as to prevent the limb 12 from
separating endwise from the handle 11.
The pin or insert 19 is normally retained in the socket 20 by the
leaf spring 18 which restrains forward tipping of the limb 12 with
respect to the handle.
The tapered shape of the lower end 16 of the limb prevents any
binding of the limb in the recess 15 when the limb is tipped
forwardly for removal from the handle.
In the normal operation of the bow, the spring 18 maintains the pin
or insert 19 and socket 20 in coupled relationship so as to prevent
any accidental or undesired separation of the limb 12 from the
handle 11 while the limb is in relaxed condition.
When the bow is strung so as to adjust the string 14 in a position
to facilitate shooting, the limbs 12 are both flexed in the
direction of arrow F in FIG. 2, and are retained in this state of
flection until the bow is again let down. While the bow is strung
as illustrated in FIG. 1, the lower end 16 of the limb bears
forwardly against the strap 17 and rearwardly against the rear side
of the recess, particularly adjacent the upper portion of the
recess 15 so as to establish a very rigid relationship between the
limbs and the handle.
When an arrow is applied to the string and laid across the arrow
rest on the handle, the bow may be drawn so as to additionally flex
the limbs 12 in the direction of arrow F, and this flexing has no
undesirable effect at all on the joint between the limbs and the
handle. The pressure applied against the strap 17.3 and against the
rear side 11.2 of the recess, is somewhat increased and the
rigidity between the limbs and the handle is therefore increased.
As the string and arrow are released so as to cast the arrow
forwardly, the limbs 12 return to the position illustrated in FIG.
1 wherein the lower end 16 of the limb continues to apply
substantial pressure against the rear side 11.2 of the recess and
against the strap 17.3 defining the front side of the recess 15. It
can be said that this bow operates like a conventional bow and has
no adverse effect upon the casting of an arrow.
When shooting has been completed, the bow may be let down so that
the tension on the string 14 is relieved and the limbs 12 return to
relaxed position. When this condition exists, the limbs may be
swung or tilted forwardly in the direction of arrow A so as to tip
the lower end 16 of the limb against the spring 18 and separate the
socket 20 from the insert or pin 19. After this tipping occurs, the
limb 12 may be withdrawn endwise from the socket 15, and the bow
may thereby be taken down for storage within a small space.
When the bow is to be again prepared for shooting, the inner end 16
of the limb may merely be inserted into the space between the pin
19 and the spring 18 and then inserted downwardly into the recess
15 until the socket 20 seats against the pin 19 under influence of
the spring 18. The bow may be strung up to the position of FIG. 1,
whereupon the bow is ready for shooting.
It will be seen that I have provided a new and improved demountable
bow wherein the limbs are demountable from the handle by means of a
connection involving a recess in the handle into which the inner
end of the limb is extended. The limb is removed by simply tilting
it forwardly so as to uncouple the pin and socket which normally
restrains the limb from endwise separation from the handle.
Normally, while the bow is unstrung and in relaxed condition, the
leaf spring retains the insert or pin and socket in coupled
condition. When the bow is strung up and shot, it operates like any
other bow.
