본 고안은 의자의 다리에 달아서 이동시에는 구를 수 있고 사람이 앉았을 시는 구르기 않고 정지하도록하는 의자의 이동 및 제지장치에 관한 것이다.The present invention relates to a device for moving and restraining a chair attached to a leg of a chair so that the user can roll when moving and stop without rolling when a person sits down.
종래의 의자 다리에 다는 바퀴는 빈 의자일때 의자를 이동시키려면 밀어서 굴릴 수 있고 사람이 앉았을 때도 앉아 있는 채로 밀고 굴릴 수 있는 것이었기 때문에 이동할 필요가 없을 때에도 앉은 사람의 몸의 자세의 변동에 의해서 의자가 스스로 굴러가서 불필요하게 이리저리 이동하게되는 폐단이 있었다.The wheels on the conventional chair legs can be pushed and rolled to move the chair when it is an empty chair, and can be pushed and rolled while sitting, even when a person is seated. There was a pulsation that would roll over and move around unnecessarily.
본 고안은 이와 같은 폐단을 없애기 위하여 사람이 앉았을 때는 의자 스스로 구르지 않고 제지되게 하므로서 안정된 의자를 제공하는데 목적이 있다.The present invention aims to provide a stable chair by allowing the chair to be restrained without rolling the chair itself when a person sits in order to eliminate such a waste.
본 고안의 구성을 도면에 의하여 상세히 설명하면 다음과 같다.Referring to the configuration of the present invention in detail as follows.
제 1 도, 제 2 도 및 제 3 도에서 바퀴(1)(1')는 니들 베어링(2)을 개재하여 바퀴축(3)에 꽂고 바퀴축(3)은 바퀴축 지지간(6)(6')의 양단에 뚫린 바퀴축 지지공(4)(4')에 끼운후 바퀴축지지와셔(5)(5')로 고정한다.In FIG. 1, FIG. 2 and FIG. 3, the wheel 1, 1 'is inserted into the wheel shaft 3 via the needle bearing 2, and the wheel shaft 3 is connected to the wheel shaft supporting section 6 ( 6 ') is inserted into the wheel shaft support hole (4) (4') drilled at both ends and fixed with the wheel shaft support washers (5) (5 ').
이와 같이 전후 두개의 바퀴를 달아서 바퀴세트(10)를 구성하는 것이다. 바퀴축 지지간(6)(6')의 중심부에는 현가(懸架)축 지지공(7)(7')을 뚫고 현가축(8)을 관통 삽입하되 현가장치(20)의 현가축 작동용 수직장공(12)을 중심부에서 관통시켜 현가장치를 현가토록하고 현가축(8)의 양단은 현가축지지와셔(9)(9')를 끼워서 고정한다.In this way, the front and rear two wheels to configure the wheel set 10. Insert the suspension shaft support hole (7) (7 ') through the suspension shaft support hole (7) (7') in the center of the wheel shaft support section (6) (6 '), but the vertical suspension for suspension axis operation of the suspension device (20) The long hole 12 is penetrated at the center to suspend the suspension device, and both ends of the suspension shaft 8 are fixed by inserting the suspension support washers 9 and 9 '.
현가장치(20)는 상부에 의자고정편지지공(14)이 뚫리고, 하방전후 4개소에 걸림편 걸림구멍(13)(13')이 있는 현가상자(11) 밑으로 부터 브레이크브럭(30)을 삽입고정 하여서 구성되는데, 브레이크브럭(30)은 브레이크명판(26)위의 중앙부에 스프링지지판(21)이 일체로 형성되고, 이 스프링지지판(21)을 보강하면서 현가상자(11)의 걸림편 걸림구멍(13)(13')에 삽통되어 걸리도록한 현가상자 걸림편(23)(23')을 앞뒤로 형성하고 스프링지지판(21)과 평행방향으로 안내편(22)(22')을 직립구성하여 스프링지지구(32)(32')를 안내편(22)(22')사이에 세우면서 이 스프링 지지판(21)과 안내편(22)(22')사이의 양모서리에 각각 끼워지도록 구성한 것이다.Suspension device 20 is a chair fixing piece support hole 14 is drilled in the upper portion, and the brake block 30 from the bottom of the suspension box 11 having the locking piece engaging holes 13, 13 'in four places after the downward discharge. It is configured by inserting and fixing, the brake block 30 is a spring support plate 21 is integrally formed in the center portion on the brake name plate 26, while holding the latch of the suspension box 11 while reinforcing the spring support plate 21. Suspension box locking pieces 23 and 23 ', which are inserted into and held by the holes 13 and 13', are formed back and forth, and the guide pieces 22 and 22 'are erected in a direction parallel to the spring support plate 21. The spring supports 32, 32 'between the guide pieces 22, 22' and fitted to the two edges between the spring support plate 21 and the guide pieces 22, 22 ', respectively. will be.
스프링지지판(21)에는 스프링지지홈(24)과 현가축 걸림홈(25)을 절결하여 형성한다.The spring support plate 21 is formed by cutting the spring support groove 24 and the suspension shaft engaging groove 25.
이 스프링지지판(21), 현가상자 걸림편(23)(23') 스프링지지구(32)(32') 및 안내편(22)(22')은 프라스틱 사출성형으로 모두함께 일체로 성형할 수도 있다.The spring supporting plate 21, the suspension box locking pieces 23, 23 ', the spring supports 32, 32' and the guide pieces 22, 22 'may all be integrally molded together by plastic injection molding. have.
전기한 바퀴세트(10)에 브레이크브럭(30)이 삽입된 현가장치(20)를 결합한후 코일스프링(31) 하단을 현가축(8)위에 얹고, 그 코일스프링 상단은 스프링 지지돌기(35)로 스프링(31)의 위치를 맞추면서 스프링받이(34)를 덮고 그 위에서 의자 고정편(36)을 누르면서 의자 고정편 지지공(14)에 끼워 넣어서 완성하는 구조이며, 의자(40)는 의자고정볼트(38)로서 의자고정편(36)상에 뚫린 의자 고정넛트(37)에 나작함으로서, 현가장치(20)상부에 고정된다.After combining the suspension device 20 into which the brake block 30 is inserted into the wheel set 10, the lower end of the coil spring 31 is placed on the suspension shaft 8, and the upper end of the coil spring is a spring support protrusion 35. It is a structure that is completed by covering the spring receiving 34 while adjusting the position of the low spring 31 and inserting it into the chair fixing piece support hole 14 while pressing the chair fixing piece 36 thereon, and the chair 40 is a chair fixing bolt. (38) is fixed to the upper part of the suspension apparatus 20 by screwing into the chair fixing nut 37 drilled on the chair fixing piece 36. As shown in FIG.
이와같이 구성된 본 고안의 작용, 효과를 설명하면, 제 2 도에서 의자(40)에 부하가 걸리지 않았을때 즉 사람이 앉지 않았을 때에는 현가축(8) 상에 얹혀진 코일스프링(31)의 탄발력에 의해 스프링받이(34)가 윗쪽으로 떠밀려지고 이 스프링받이는 현가장치(20)상부의 의자고정편지지공(14)에 끼워져 고정된 의자고정편(36)저면에 맞닿아 있으므로 현가장치(20)와 그 하부에 고정된 브레이크브럭(30)은 바퀴 축지지간(6)(6')사이의 현가축(8)상에서 윗쪽으로 떠있게되고, 브레이크면판(26)이 바퀴(1)(1')의 최저면보다 위로 저면에서 떨어지게 됨에 따라 바퀴는 자유유동 상태가 된다.Referring to the operation and effect of the present invention configured as described above, when the chair 40 is not loaded in FIG. 2, that is, when a person is not seated, the elastic force of the coil spring 31 mounted on the suspension shaft 8 is applied. The spring bearing 34 is pushed upward and the spring bearing is fitted into the chair fixing piece support 14 of the upper part of the suspension device 20 so as to contact the bottom of the chair fixing piece 36 fixed thereto. The brake block 30 fixed to the lower portion of the brake block 30 floats upward on the suspension shaft 8 between the wheel shaft support sections 6 and 6 ', and the brake face plate 26 is connected to the wheels 1, 1'. The wheels are free-flowing as they fall from the bottom above the bottom.
한편 의자(40)에 부하가 실리면 즉 사람이 앉으면 의자는 화살표 방향으로 누르는 힘이 생기고 제 3 도와 같이 현가축 작동용 수직장공(12)의 최상단까지 현가축(8)에 안내되면서 현가장치(20)가 수직하향하게 됨과 동시에 브레이크브럭(30)하부의 브레이크면판(26)이 저면에 닿게 되므로 바퀴세트(10)에 제동력이 발생되어 구르지 못하고 의자(40)는 그 자리에 안착되게 되는 것이며, 이때 코일스프링(31)은 현가축(8)과 스프링받이(34)사이에서 압축되어 의자 상에서 부하가 제거되면 다시위로 떠밀어 올리려는 탄발잠재력을 갖게된다.On the other hand, when the load is loaded on the chair 40, that is, when the person sits down, the chair has a pressing force in the direction of the arrow and guides the suspension shaft 8 to the top of the vertical long hole 12 for suspension operation as shown in the third way. At the same time as the 20 is vertically downward, the brake face plate 26 of the lower part of the brake block 30 comes in contact with the bottom, and thus, the braking force is generated on the wheel set 10 and the chair 40 is not seated. At this time, the coil spring 31 is compressed between the suspension shaft 8 and the spring bearing 34 to have a shot potential to push up again when the load is removed from the chair.
이와같이 본 고안은 의자외에도 집회장, 강의실, 연수실등의 강단 및 연극영화등의 무대 세트 등에서 범용적으로 사용할 수 있다.In this way, the present invention can be used universally in stage sets, such as pulpits such as meeting halls, lecture rooms, training rooms, and theater films.
상기 같은 작용에 의해서 짐을 설치 않았을 때는 자유자재로 굴려서 이동가능하나 일단 짐을 실은후에는 요지부동으로 안착되어 절대로 안정을 유지하는 효과가 있다.When the load is not installed by the same action, it can be rolled freely and moved, but once loaded, the seat is seated with the main body and has an effect of absolutely maintaining stability.
