본 고안은 의자의 좌판이 사람이 착석후 기립하면 스프링에 의해 자동으로 입설되는 의자좌판의 기복탄력장치에 관한 것이다.The present invention relates to a relief device of the chair seat that is automatically entered by the spring when the seat plate of the chair stands up after a person is seated.

종래에도 의자의 좌판이 스프링의 탄력으로 입설되는 장치가 있었으나 주로 좌판하부의 고정축이 양측판과 베어링으로 회전되면서 스프링의 탄력으로 입설되는 것으로 좌판에 고정된 하부축이 양측판에서 회전되기 위한 베어링 장치구조와 베어링의 마모시 교체방법 등이 복잡하고 좌판이 착석시와 기립시 스프링의 탄력으로 상, 하부에서 제한하는 양측판의 제한돌기와의 접촉충격으로 소음이 발생하는 결점이 있었다.Conventionally, there was a device in which the seat plate of the chair was installed by the elasticity of the spring, but mainly the fixed shaft of the seat under the seat was rotated by both side plates and bearings, so that the bottom shaft fixed to the seat was rotated on both side plates. The device structure and replacement method of bearing wear are complicated, and the seat plate has the defect that the noise occurs due to the impact of contact with the limiting protrusions of the upper and lower plates, which are restricted at the upper and lower sides due to the spring elasticity when seating and standing.

본 고안에서는 이와 같은 결점들을 개선하고져 양측끝단이 4각축단으로 형성된 환봉축의 가운데에 중공체좌판을 횡으로 삽입시키고 이 환봉축의 양쪽에서 코일스프링으로 중공체좌판이 탄발력으로 조정이 되게 결속시키고 이 양외측으로는 외측벽후부상단에형 패킹을 결속시킨형 패킹 결속구가 돌출되고 측벽중간의 축삽입공에는 선단부가 상하로 절개된 걸림턱으로 조립이 용이한 합성수지베어링을 압삽시킨형 철재받침판을 합성수지 베어링이 양측끝단의 4각 축단을 지나 환봉축에 축설되게 나사못으로 중공체좌판과 체결시켜서 중공체좌판이 고정된 환봉축에 양측후부쪽 철재받침의 합성수지 베어링으로 축설되어 상하로 회전되게 하고 양측으로 노출된 4각축단을 측판내측 중간의 상부걸림단과 전방걸림단으로 형성된형 제어축대 중간의형 결속축대에 나사못으로 고정시켜 착석시 중공체좌판이 전방으로 회전하여 철재받침판의형 패킹 결속구에 결속된형 패킹의 상부면이 제어축대의 상부걸림단에 걸리면서 충격이 없이 부드럽게 수평유지가 되고 착석후 기립하면 중공체좌판이 코일스프링의 탄력으로 상향으로 회전하여 패킹결속구의 패킹저면이 제어축대의 전방걸림단에 걸려서 충격과 소음이 없이 자동으로 입설될 수 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention, these defects are improved, and the hollow body seat is inserted transversely in the center of the round bar shaft formed at the both ends of the four-axis ends, and the hollow body seat is fixed with elastic force by the coil springs on both sides of the round bar shaft. On both sides of the outer wall Binding Mold Packing The type packing binding hole is protruded and the synthetic insert bearing is inserted into the shaft insertion hole in the middle of the side wall by the locking jaw whose tip is cut up and down. The steel bearing plate is fastened to the round bar shaft by the synthetic bearings across the four-axis shafts at both ends and screwed together with the hollow seat plate. It is rotated and the quadrilateral shaft exposed to both sides is formed by the upper and the front locking end of the middle of the side plate. Type control shaft middle When the seated body is fixed with a screw with a screw, the hollow body seat rotates forward to Bound to mold packing brace When the upper surface of the mold packing is caught by the upper locking end of the control shaft, it is horizontally maintained smoothly without impact. When standing, the hollow body seat rotates upward with the elasticity of the coil spring, and the packing bottom of the packing binding port is caught by the front of the control shaft. It can be automatically entered without a shock and noise due to the stage described in detail according to the drawings as follows.

양측끝단이 4각축단(10a)으로 형성된 환봉축(10)의 가운데에 중공체좌판(1)을 양측후부쪽 저면코너의 함입부에 횡으로 관통된 축심공(2)으로 삽입시키고 이 환봉축의 양쪽에는 코일스프링(12)을 내측의 축방향쪽 고정끝단(13)으로 환봉축(10) 하부에 부착된 수개결속공(11)에 탄력강도에 맞게 선택하여 삽입시키고 외측의 전방쪽걸림끝단(14)으로는 중공체좌판이 탄발되도록 저면요입홈(3)에 접속시키고 이 양측후부쪽 저면코너의 함입부에는 외측벽 후부상단에형 패킹(22)을 결속시킨형 패킹 결속구(21)가 돌출되고 측벽중간의 축삽입공에는 합성수지베어링(23)을 선단부가 상하로 절개가 된 걸림턱(23a)으로 압삽시킨형 철재받침판(20)을 양측끝단의 4각축단을 지나 합성수지베어링(23)이 환봉축(10)에 축설되게 나사못으로 중공체좌판에 체결시킨후 철재받침판(20)의 양측으로 노출된 4각축단(10a)을 축판(30) 내측중간의 전부쪽에 상부걸림단(33)과 전방걸림단(34)으로 형성된형 제어축대(31) 중간의형 결속축대(32)에 나사못으로서 고정시켜서 된 것으로 미설명부호 (35)는 등판지지대이다.Insert the hollow seat plate 1 into the center of the round bar shaft 10 formed at both ends of the axial end 10a through the axial bore 2, which is laterally penetrated into the recess of the bottom corner of the rear side, and the round bar shaft. On both sides of the coil spring (12) to the inner axial fixed end 13 of the inner rod shaft (10) attached to the number of fastening holes (11) attached to the lower portion of the selected according to the elastic strength and the outer front hook end (14) is connected to the bottom concave groove (3) so that the hollow body seat plate is resilient. Binding Mold Packing (22) The shaped packing binding hole 21 protrudes and the synthetic resin bearing 23 is pressed into the locking jaw 23a in which the distal end is cut up and down in the shaft insertion hole in the middle of the side wall. The square steel support plate 20 is passed through the four-axis shaft ends of both ends, and the synthetic resin bearing 23 is fastened to the hollow body seat with screws to be laid on the round bar shaft 10, and then the four-sided shaft exposed to both sides of the steel support plate 20. The end 10a is formed as an upper locking end 33 and a front locking end 34 on all of the inner middle of the shaft plate 30. Type control shaft (31) The screw 35 is fixed to the type binding shaft 32, and the reference numeral 35 is a back support.

이와 같은 구조로된 본 고안은 양측끝단이 4각축단(10a)으로 형성된 환봉축(10)의 가운데에 중공체좌판(1)을 횡으로 관통된 축심공(2)으로 삽입시키고 이 환봉축의 양쪽에는 코일스프링(12)으로 내측의 축방향쪽 고정끝단(13)은 환봉축하부에 부착된 수개결속공(11)에 기복되는 중공체좌판의 탄력강도에 맞추어 위치를 선택하여 삽입시키고 외측의 전방쪽걸림 끝단(14)은 중공체좌판(1)이 탄발되게 저면요입홈에 접속시켰으므로 환봉축은 고정되고 이 환봉축에 중공체좌판의 코일스프링(12)으로 탄발되면서형의 철재받침판(20)의 합성수지베어링(23)에 축설되었으므로 착석시 중공체좌판이 전방으로 회전되었다가 기립하면 코일스프링의 탄발로 중공체좌판이 자동으로 입설되는 것이며 이렇게 환봉축을 중심으로 기복될 수 있는 중공체좌판을 측판(30) 내측중간의 전부쪽에 돌출왼형 제어축대(31) 중간의형 결속축대(32)에 철판받침판의 양측으로 노출된 환봉축의 4각축단(10a)으로 고정시켰으므로 착석시 중공체좌판이 철재받침판(20)의 합성수지베어링(23)에 의해 전방으로 회전되면서 철재받침판의형 패킹결속구 (21)에 결속된형 패킹(22)의 상부면이 측판(30)형 제어축대(31)의 상부걸림단(33)에 걸려서 패킹의 탄력성으로 충격없이 부드럽게 지지가 되어 중공체좌판이 수평을 유지할 수가 있고 기립하면 코일스프링의 탄력으로 중공체좌판(1)이 자동으로 입설되면서 이때 철재받침판의 패킹결속구(21)의 패킹(22)의 저면이 측판(30) 제어축대(31)의 전방걸림단(34)에 걸려서 코일스프링의 탄발을 패킹의 탄력성으로 흡수시켜 소음과 충격이 없이 입설될 수가 있는 것이다.The present invention having such a structure inserts the hollow body seat plate (1) into the axial bore hole (2) transversely in the center of the round bar shaft (10) formed at both ends of the four-axis shaft (10a) and the On both sides of the coil spring 12, the inner axial fixed end 13 of the inner side is selected and inserted in accordance with the elastic strength of the hollow body seat plate undulated to the several binding holes 11 attached to the lower end of the round rod shaft. Since the front end 14 is connected to the bottom recess groove so that the hollow body seat 1 is repulsed, the round bar shaft is fixed and is reeled with the coil spring 12 of the hollow body seat plate to the round bar shaft. Since the hollow bearing seat is rotated forward when standing, the hollow bearing seat is automatically placed by the coil spring's coil when it is seated on the synthetic resin bearing 23 of the steel support plate 20 of the type. The hollow body seat can protrude left side of the side plate 30 inside Type control shaft (31) Since the fixing member is fixed to the square shaft end 10a of the round bar shaft exposed to both sides of the steel plate support plate 32, the hollow body seat plate is rotated forward by the synthetic resin bearing 23 of the steel support plate 20 when seated. Of steel support plate Bound to mold packing Binding Sphere (21) The upper surface of the mold packing 22 is the side plate 30 The hollow body seat plate (1) is automatically supported by the elasticity of the coil spring when it is caught by the upper locking end (33) of the mold control shaft (31) and is supported smoothly without impact due to the elasticity of the packing. While being placed, the bottom of the packing 22 of the packing fastener 21 of the steel support plate is caught by the front catching end 34 of the side plate 30 control shaft 31 so that the coil spring of the coil spring is absorbed by the elasticity of the packing to make noise. It can be entered without excessive impact.

이상과 같이 본 고안은 환봉축(10)은 고정되고 중공체좌판이 양측의 철재받침판에 압삽된 합성수지베어링(23)에 의해 축설되어 회전되므로 구성이 간단하고 장기간 사용하여 합성수지베어링이 파손시에는 교체가 매우 용이한 것이다.As described above, the present invention is a round bar shaft 10 is fixed and the hollow body seat plate is installed by rotating the synthetic resin bearing 23 is pressed in the steel support plate on both sides, so the configuration is simple and replaces when the synthetic resin bearing is damaged for a long time use Is very easy.
