[62] A cushion 81 is placed on the upper side of the elevating portion 3 and the supporting member 5, and is elastically supported by the elevating portion 3 and the plurality of springs 80. Top plate 8 is provided.
[63] The top plate 8 is connected to the lift / lower portion 3 via a spring 80 to be constantly operated upward.
[64] The operation of the present invention configured as described above will be described.
[65] Figure 1 is an overall exploded perspective view of the present invention, Figure 2 is a front view showing the first coupled state of the present invention, Figures 3 to 4 in accordance with operating the operating lever applied in the present invention wins The perspective view is shown in which the lowering part is operated and the support member and the top plate move upwards.
[66] As shown in the drawing, a state before use, or a folded state, of the pillow according to the present invention becomes a state as shown in FIG. 2.
[67] That is, in the first state as described above, the spring 80 which interconnects the top plate 8 and the lifting and lowering portion 3 side is kept in a tensioned state, but the connecting bar of the lifting and lowering portion 3 is maintained. (37) The bent portion of the actuating pin 38 is in close contact with the inclined portion 37a provided on one side, and the through bar of the guide portion 4 fitted in the polygonal groove 38a of the actuating pin 38 ( 42 is a state in which the outer circumferential surface thereof is in contact with the inner circumferential surface of the groove 38a and is in contact with each other and overcomes the elastic restoring force of the spring 80.
[68] In the above state, the outer circumferential surface of the polygonal lifting and lowering guide bar 35 positioned inside the polygonal hole 34a formed in the lifting and lowering guide tube 34 of the lifting and lowering part 3 is also formed. It is in a state of being supported so as not to move in a state of being in close contact with the inner circumferential surface of the hole 34a.
[69] When the height of the pillow is adjusted in the initial state as described above, the operation lever 2 protruding to both sides of the outer frame 11 is moved in one direction.
[70] As described above, when the operation lever 2 is moved in one direction, the operating rod 21 and the operation piece 22 which are integrally connected to the operation lever 2 are sequentially moved, and the operation rod fitted to the operation piece 22 ( 23) is moved in one direction.
[71] As described above, when the operating rod 23 is moved in one direction, the connecting bar 37 connected to the operating rod 23 is moved in one direction, and accordingly, the inclined portion 37a installed in the connecting bar 37 is It is moved in one direction while overcoming the elastic restoring force of the elastic pin 39 held on the operation pin 38 supported on the inclined surface.
[72] When the inclined portion 37a provided in the connecting bar 37 moves in one direction while overcoming the elastic restoring force of the elastic pin 39, as shown in a to b of FIG. 6, the operation pin 38 and the connection are provided. The bar 37 is parallel so that the through bar 42 penetrating the polygonal groove 38a formed in the actuating pin 38 is slidable therein.
[73] In addition, at the same time, the operation piece 23a provided on both sides of the operating rod 23 is pushed upward of the lower side of the lifting and lowering guide piece 36 located above the upper and lowering guide pieces 36. ) Is to overcome the elastic force of the elastic member (36a).
[74] Therefore, the lifting and lowering guide bar 35 which penetrates inside the polygonal hole 34a formed in the lifting and lowering guide tube 34 can slide without contacting each other like the operation pin 38 described above. As it is going up and down member 30 is to be moved upward.
[75] On the other hand, at this time, the left and right moving gears 41 of the guide portion 4 is centered in the state of meshing with the drive gear 40a formed in the pair of the guide gear 40 as shown in b of FIG. The axis is moved in parallel in opposite directions on both sides, and smoothly guides all the above operations.
[76] As a result, the elevating / lowering member 30 of the elevating / lowering portion 3 is caused by the elastic restoring force of the spring 80 which is mutually supported between the top plate 8 and the elevating / lowering portion 3. Is lifted by crossing a plurality of pins upwards on the axis.
[77] At this time, the supporting member arranged at the outermost side of the supporting member 5 and the inner supporting member connected by the torsion spring 51 are first lifted by the operation of the torsion spring, and the other supporting members disposed therein are Subsequently, it is lifted up sequentially.
[78] In addition, all of the above series of operations are performed simultaneously, and if the operation of the operation lever 2 which has been operated is released, all the above operations are in the original position and the inclined portion attached to the connection bar 37 and one side thereof. The operation pin 38 is again positioned at the portion where the inclination of the 37a starts, and the elastic pin 39 is pressed by one side of the elastic pin 39 to maintain the initial state, that is, the fixed state.
[79] Here, when the height of the elevating and lowering member is operated as described above, when the height is arbitrarily adjusted, the operating lever 2 is operated again, and then the elevating top plate 8 can be pressed downward to arbitrarily adjust the height.
[80] Of course, the lifting / lowering member lifted and lowered by the above operation is lifted to the height of the highest point.
[81] On the other hand, in the above state, for example, when operating the height adjustment unit 6 to adjust the height of the pillow step by step to rotate the control dial 61 exposed to the outside of the outer frame 11 in one direction The drive pulley 60 is rotated, and the driven pulley 62 is rotated through the belt 63, and the rotating shaft 64 is idling accordingly.
[82] However, the stopper 66 screwed to the screw thread 65 is moved forward or backward in one direction or the other direction according to the rotation direction even when the rotation shaft 64 is idle.
[83] As described above, when the stopper 66 is moved in one direction or the other direction and stops at the set position, the stopper 66 is positioned on the stopper 66 side even if the stopper 66 tries to move upward as in the operation of the lifting and lowering unit 3. Since the edge provided on the edge side of the left and right shifting gears 41 is supported by the stopper 66, only the position where the stopper 66 is installed is movable.
[84] Therefore, at this time, the height can be adjusted by adjusting the distance by which the raising / lowering member 30 opens as much as possible by moving the stopper 66 to the left and right.
[85] In addition, when the adjustment dial 61 is rotated as described above, the adjustment gear 67 is integrally rotated to move the flexible rack gear 68 engaged thereunder in one direction and the other direction. At the same time, the display unit 68a provided at one end of the rack gear 68 is moved while being exposed to the outside of the outer frame 11 and reaches the height indication scale formed on the upper side of the plate, so that the appropriate height can be adjusted. Will be.
[86] On the other hand, when operating the height maintaining unit 7 operates the lever 70 exposed to the outside of the outer frame 11 in one direction.
[87] When the lever 70 is operated as described above, the operation shaft 71 is rotated, and the rotary cam 76 installed at one side thereof rotates while generating a "click" sound.
[88] Therefore, the stopper 75 placed on the upper side thereof, that is, the ball 75c held on the spring 75b provided on the inner side of the tubular body 75a has the elasticity of the spring 75b. Limited by the ball 75c in contact with the restoring force, the operation thickening portion 71a provided on the other side thereof is flipped to one side in a state of supporting the catching jaw 73 provided in the stop member 72 upward. At the same time, the support state is released.
[89] As a result, the stop member 72 is moved to the lower side by the elastic restoring force of the torsion coil spring 79, and thus the locking jaw 73 'positioned at the lower side is one side of the left and right moving gear 41. Since the support plate is supported on the inner side of the locking plate 74 provided on the upper side, the left and right movement gears 41 are prevented from moving inward.
[90] Therefore, since the left and right moving gears 41 are operated only up to the engaging jaw 73 'of the stop member 72 moved downward by the operation of the lever 70, the lifting and lowering part 3, that is, lifting and lowering. The height of the member 30 is limited.
[91] According to the pillow according to the present invention as described in detail above, by adjusting the height of the pillow according to the user's taste and purpose of use, there is an effect of providing convenience in use.
[92] Until now illustrated and described with respect to the preferred embodiments according to the present invention, but not limited to this can be variously changed and used by those skilled in the art.
[93] However, it is apparent that such modifications fall within the scope of the present invention.
