Description
【０００１】[0001]
この考案はウレタン駒の補強構造に関するものである。 This invention relates to a structure for reinforcing a urethane piece.
【０００２】[0002]
従来、ウレタン駒は図４に示すように連結方向の両端に連結用のピン孔を形成 してメタル駒と交互に噛合わせとピン連結し、またはウレタン駒のみの噛合わせ とピン連結にてバンドを編成してきたものである。 Conventionally, urethane pieces have pin holes for connection at both ends in the connection direction, as shown in Fig. 4, and are alternately engaged with metal pieces and pin-connected, or only urethane pieces are engaged and pin-connected. Has been organized.
【０００３】[0003]
しかしながらウレタン駒はメタル駒より強度が弱いため、バンドに引張圧力が 加わったりすると、連結部分が弛み、または裂断してバンドが分解するというお それが生ずる。 However, since the urethane piece is weaker than the metal piece, if a tensile pressure is applied to the band, the connecting part may be loosened or torn and the band may be disassembled.
【０００４】[0004]
本考案は、ウレタン駒の裏面の連結方向に１条乃至数条にて補強用溝を設け、 該補強用溝に金属板等にてなる補強骨格を組込み、該各補強骨格の連結方向の両 端にウレタン駒と連通する連結用のピン孔を設けて、連結用ピンをウレタン駒と 補強骨格にて受け止めるようにして、かかる課題を解決するようにしたのである 。 In the present invention, one or several reinforcing grooves are provided in the connecting direction of the back surface of the urethane piece, and a reinforcing skeleton made of a metal plate or the like is incorporated in the reinforcing grooves, and both ends of the reinforcing skeleton in the connecting direction are connected. In order to solve such a problem, a connecting pin hole communicating with the urethane piece is provided on the urethane piece, and the connecting pin is received by the urethane piece and the reinforcing frame.
【０００５】[0005]
以下図面に基づいて説明する。 This will be described below with reference to the drawings.
【０００６】 連結方向の両端に連結用の軸孔１１を穿設した噛合わせ用の外側突出部１２a ，１２bを有すメタル駒１３と同径の軸孔１１を設けた内側突出部１４a，１４b を有すウレタン駒１５を形成する。ウレタン駒１５は裏面の内側突出部１４a， １４b間に間隔を置いて２条の補強用溝１６ａ，１６ｂを設け、該補強用溝１６ ａ，１６ｂに金属板の打ち抜きにてなる金属骨格１７ａ，１７ｂを嵌め組込みす る。[0006] Inner protrusions 14a, 14b provided with shaft holes 11 having the same diameter as metal pieces 13 having engagement outer protrusions 12a, 12b having connection shaft holes 11 formed at both ends in the connection direction. Is formed. The urethane piece 15 is provided with two reinforcing grooves 16a, 16b at intervals between the inner protruding portions 14a, 14b on the back surface, and the reinforcing grooves 16a, 16b are provided with a metal skeleton 17a formed by punching a metal plate. 17b is fitted and assembled.
【０００７】 金属骨格１７ａ，１７ｂの両端にはピン孔１１に連通するピン孔１１ａ，１１ ｂが形成される。なお金属骨格１７ａ，１７ｂは図２，図３に示すように両端上 部に突出部１８ａ，１８ｂを設けてウレタン駒１５の両端から見える形状にして いるが、これは耐衝性を強化するため太めの連結用ピン１９を使用し得るように ピン孔１１ａ，１１ｂを大きくしたからであって、ピン１９を通常径とするとき は突出部１８ａ，１８ｂの形成は必要ないこととなる。[0007] At both ends of the metal skeletons 17a and 17b, pin holes 11a and 11b communicating with the pin holes 11 are formed. As shown in FIGS. 2 and 3, the metal skeletons 17a and 17b are provided with protrusions 18a and 18b at the upper ends thereof so as to be seen from both ends of the urethane piece 15. This is because the pin holes 11a and 11b are enlarged so that the thicker connecting pin 19 can be used. When the pin 19 has a normal diameter, the projections 18a and 18b need not be formed.
【０００８】 このように形成したメタル駒１３とウレタン駒１５は交互に噛合わせ、連通す るピン孔１１，１１ａ，１１ｂに連結用ピン１９を挿着して駒間を連結してバン ド２０を編成するのである。The metal pieces 13 and the urethane pieces 15 thus formed are alternately meshed with each other, and connecting pins 19 are inserted into the communicating pin holes 11, 11a and 11b to connect the pieces to form a band 20. Is organized.
【０００９】 また図示してないが金属骨格１７ａ，１７ｂを組込んだウレタン駒同士の噛合 わせとピン１９の挿着にてバンド２０を編成することもできる。Although not shown, the band 20 can be formed by mating urethane pieces incorporating the metal skeletons 17a and 17b and inserting the pins 19.
【００１０】[0010]
本考案は以上のようにして、ウレタン駒の連結方向の裏面に１条乃至数条にて 金属板等による補強骨格を組込み、該補強骨格の両端にウレタン駒と連通する連 結用のピン孔を設けてピン孔を補強強化するようにしたので、ウレタン駒が強度 においてメタル駒より弱いにかかかわらず、連結部はメタル駒と同等の強度を有 して引張圧力が加わってもみだりに駒間が弛んだり、裂断しないという効果を生 ずる。 As described above, in the present invention, a reinforcing skeleton made of a metal plate or the like is assembled on the back surface in the connecting direction of the urethane piece in one or several lines, and connecting pin holes communicating with the urethane piece are provided at both ends of the reinforcing skeleton. Since the pin holes are provided to reinforce and reinforce the pin holes, the connection part has the same strength as the metal piece, and the gap between the pieces is unobtrusive even if tensile pressure is applied, regardless of whether the urethane piece is weaker in strength than the metal piece. It has the effect of not sagging or tearing.
