BUTTON IN TWO PARTS
Karel Vesely, Pilsen, Czechoslovakia
Application July 3, 1936, Serial No. 88,871

6 Claims.
The object of the invention is a button in two
parts which can .be fixed to its support Without
sewing, etc. by pulling a loo-p of the under por
tion through and subsequently pressing this
5 loop‘into a slot Ain `the upper portion of the b-ut
ton.
Several embodiments of
the invention are
shown‘in the accompanying drawings.
Fig. Y1 shows the upper parts of the button
it» with an auxiliary insert in the open position, in
a section along line vI--I of Fig. 3.
Fig. 2 shows the under part of the button in a
section along line I-l of Fig. 3.
Fig. 3 shows the upper part of the button seen
from beneath.
AFigs. 4 and 5 show a section along line III-III
of Fig. 3.
Figs. 6 and 7 are similar to Figs. 1, 2 and 3 and
correspond with the appearance of the button in
20 the »closed position.
Figs. 8, 9, »10 and 11 show two kinds of embodi
ment-of the fixing member in the open and closed
positions respectively.
Figs. 12, 13 and 14 show in longitudinal sec
25 tion another embodiment of the middle part of
the button, the auxiliary insert in the open po
sition, at the beginning of closing and in the
closed position respectively.
Figs. (l5 and 16 are perspective views of two
so embodiments of the auxiliary insert.
‘Figs '17, '18 and 19 show three different em
bodiments of the lower part of the button.
The button according to Figs. 1 to 9 consists
of an upper portion I of usual form having an
3f, axial opening or slot 2, a circumferential groove
3 on yits underside Land a radial bore 4. In the
groove there is carried a securing member of
which the two bow-like side pieces 5 resilientiy
embrace the button portion and of which the
40 central locking pin 6 projects into the radial
50
(Cl. 24-106)
then placed over the pin or loop 9.
As a re
sult of this, the point of the pin 9 raises the aux
iliary insert 1 and moves it out of the path of
the locking pin 6. After further movement, the
opening 19 in the pin 9 comes opposite to the
locking pin 6, which under the influence of its
side parts 5, springs into the opening Ill where
by the button is secured in position (see also
Figs. 8 to 9).
The securing element with the locking pin 5,
5 can also be otherwise formed as is shown, for
example in Figs. 10 and 11 Where the locking
pin 6 is provided with only one side piece 5 em
bracing the upper part of the button. The se
curing element 5, 6 is preferably arranged in
the groove 3 provided underneath the upper
part of the button.
The auxiliary insert 1 and its mode of opera
tion is shown to a larger scale in Figs. 12 to
lifi. Fig. l2 shows the components in the posi
tion before closing the button, Fig. 13 at the
beginning of closing and Fig. 14 in the closed
position.
In Figs. 15 and 16 two embodiments of the
auxiliary inserts are shown in perspective. 'I'he
insert 1 is made of any suitable material, prefer
ably of sheet metal.
One purpose of the insert 1 is to retain the
securing element 5, 6 in tension condition before
the two parts of the button are joined.
The .
point o-f the securing element 5, E abuts against
one wall of the insert 1. The securing element
5, 6 is prevented from penetrating into the bore
4 of the button head as long as the insert 1 in
the bore 4 is not shifted.
A further purpose of the insert »1 is to receive
the point of the pin 9 of the lower part of the
button. When the two parts of the button are
joined, the point of the pin 9 enters the bore 2
in such a way as to penetrate into the hollow
bore 4. In the axial bore 2 abutment means,
comprising an auxiliary insert 1 are carried
against which the locking pin 6 abuts as a result
of the resilience of its bow-formed side pieces 5.
The lower part of the button consists of the
of the insert 1. By further pressure of the
pin 9 against the insert 1 the latter is moved in
plate 8 from which a pointed pin 9 projects.
The pin 9 presents a ilat cross section and is
provided, in its upper part, with an opening l0
opening I0 of the pin 9, thus holding the two
parts of the button together.
Prior to the joining of the two parts of the
or is formed as a loop.
button the insert 1 is retained in the bore 2
The operation of the described arrangement
is as follows:
The lower part of the button with its pointed
pin or loop 9 is pushed through the material Il
until the plate 8 lies against the underside of
55 the material. The upper part of the button is
5
such a way as to uncover the bore 4.
rIl'he se
curing element 5, 6 springs into the free opening
4 and, at the same time, passes through the
by the pressure of the securing element 5, 6
against one wall of the insert 1, thereby pressing
the insert against the opposite Wall of the bore 2.
The insert may be a solid body, as shown in
Figs. l to l1, but it is preferable to give it a hol
low shape and to make it of sheet metal bent ap 66

proximately in the shape of a U (Fig. 16) or Y
(Figs. 12 to 15), because in the latter shapes the
two arms of the insert press agamst the walls
of the bore 2 by their own elasticity, and there
by secure the insert in the bore. Another ad
vantage of such shapes consists in stabilizing
the position of pin 9 and keeping it from Wob
bling in bore 2 after the two parts of the but
ton have been joined.
The side wall I2 of the insert as shown in
Figs. 12 to 15 is beveled. 'I'he purpose of this
is not to expose the elastic part 5 of the securing
member 5, 6 to any substantial tension when in
inoperative position before the two parts of the
button are joined. In this position the point of
the pin 6 abuts against the narrow part of the
insert, and member 6 is not in full tension. ì Only
by introducing the pin 9 into the bore 2 and
thereby shifting the insert 1 will the point of
pin 6 slide along the inclined wall of insert 1
and put the elastic member 5 in a state of ten
sion. This tension is relieved after pin 6 has
slid into the hole Il) in the pin 9.
In Figs. 17, 18 and 19 are shown, three difier
ent forms of the lower part of the button, ac
cording to which the pin is either formed as
a closed (Fig. 17) or partially closed, loop (Fig.
18, 19).

The button according to the invention is se
cured in position by means of a single hand-grip
after passing the under portion through the ma
terial, and can be easily separated.
