KÁ VESELY 2,136,161 BUTTON IN TWO PARTS Filed July 5, 1936 2 Sheets-Sheet 2 JMW fw: Patented Nov. 8, 1938 2,136,161A *UNITED STATES PATENT OFFICE 2,136,161 BUTTON IN TWO PARTS Karel Vesely, Pilsen, Czechoslovakia Application July 3, 1936, Serial No. 88,871 In Czechoslovakia May 15, 1935 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 2 2,136,161 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). 30 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. What I claim is: 1. A device for effecting the releasable attach through said opening when the button head is not in use, said auxiliary member having a beveled side wall to cooperate with the face of said locking member so as to reduce the ten sion in said locking member when said button Cl head is not in use. 3. A device for attachment to textile and simi lar materials, comprising a button head having an axial opening and a radial bore communicat ing with said opening therein and also an arcu 10 ate groove thereon, an arcuate resilient member engaging said groove and embracing said button head, a locking member projecting from and secured to said arcuate member and arranged Within said radial bore, and a hollow insert mem ber placed within said axial opening where said locking member abuts against it, said. insert member being slidably arranged to allow its dis placement and passage of said locking member into said opening when said button head is in 20 use. 4. A device for effecting the releasable attach ment of pieces of textile and similar material, comprising a button head having a grooved por tion and an opening in said button head, a resil iently urged locking member having a locking tongue projecting transversely into said opening, said locking member comprising a bow embrac ing a grooved button head in one of said detach able parts and a locking tongue. and a hollow 30 auxiliary member initially placed in said opening where said locking tongue abuts against it for preventing said locking tongue from passing through said opening when said button head is ment of pieces of textile and similar material, comprising a button head, an opening formed in not in use. said button head, a locking member having the lar material, comprising a button head having form of a bow and tongue embracing a portion of said head and resiliently urged into said open 40 ing, and a hollow insert member slidably placed in said opening and adapted to form an abut ment for said locking member to prevent said locking member from passing through said open a grooved portion, an axial opening formed in said button head, a resilient member resiliently embracing said grooved portion of the said but ton head, and a locking member secured to said resilient member located in a position transverse ly of said opening and resiliently urged into the path of said opening when said button head is in C. Li 45 ing when said button head is not in use. 2. A device for eiîecting the releasable attach ment of pieces of textile and similar material, comprising a butto-n head having a grooved por tion, an opening formed in said button head, a resiliently urged locking member having a face and being resiliently urged into said opening, said locking member comprising arcuate arms engaging the said grooved portion of said but ton head and a locking tongue, and a hollow auxiliary member slidably placed in said open 55 ing where said locking tongue abuts against it for preventing said locking tongue from passing 36 5.
