The specific embodiment

Below, tilt forward and back the swing that chair sways with reference to description of drawings according to the court of the preferred embodiment of the invention.

Fig. 1 shows that court according to the present invention tilts forward and back the oblique view of the swing that chair sways, and Fig. 2 shows that court according to the present invention tilts forward and back the side view of the swing that chair sways.With reference to Fig. 1 and Fig. 2, according to the structure of swing 100 of the present invention for comprising support 110, top 120, cross bar 130, rotating shaft 140, perpendicular rod 150, chair 160.At first, thereby the support 110b of the support 110a of support 110 one sides and opposite side is spaced from each other the width of determining swing 100, and uses as the device that supports swing 100.This support 110 has " ∩ " glyph shape respectively, thereby brings into play the function of four legs.Top 120 be installed in support 110 above, play to being sitting in the function that user on the chair 160 stops rain or snow etc.And following function is also brought into play at top 120, though support 110 is fixed on ground, its top is not fixed, therefore in conjunction with and fixing this support 110, prevent that it from rocking or fall down.

Cross bar 130 is installed in the inside upper part of support 110, is made of the opposite side cross bar (not shown) that is installed in the side cross bar 130a on the side stand 110a and be installed on the opposite side support 110b.

Rotating shaft 140 is combined in the top of cross bar 130 and rotates.Form board 141 on the upper central integrally ground of cross bar 130, in order in conjunction with rotating shaft 140.And can buried bearing between board 141 and rotating shaft 140, so that the rotation swimmingly of rotating shaft 140.

Perpendicular rod 150 be from rotating shaft 140 two ends in abutting connection with the position down side extend and form, hang chair 160 in its lower end.At this, the perpendicular excellent 150a of a side and the perpendicular excellent 150b of opposite side are combined into one with rotating shaft 140 by modes such as welding, so when chair 160 moved towards front and back, each erected excellent 150a, 150b and does not take place to misplace and carry out back and forth movement simultaneously.Namely, if perpendicular rod 150 is not combined as a whole with rotating shaft 140, each perpendicular excellent 150a, 150b will move separately, thus the back and forth movement of chair 160 just has some setbacks.

For the ease of sitting down, chair 160 is provided with seat, backrest, sole, and the width of chair is directly proportional with the standoff distance of perpendicular rod 150.Integrally formed towards the vertically extending installing plate 162 of downside at the both sides of this chair 160 central portion.

Installing plate 162 possesses for the perpendicular rod 150 of combination, and at a side and the opposite side of chair 160 a side installing plate 162a and opposite side installing plate (not shown) is set respectively.At this moment, installing plate 162 has the del shape, and carries out hinge 155 combinations at the position, downside summit of del with perpendicular rod 150.

The chair 160 of combination is because its pivot is positioned at the chair downside like this, therefore have since deadweight easily toward the clockwise direction or the structure that counterclockwise tilts.

On the other hand, as previously mentioned if chair 160 forward or towards rear-inclined, the user just can not take chair or play on a swing, the locating part that therefore needs the restriction chair to rotate.

Locating part 170,180 is in 160 liang of side-prominent formation of chair, and is divided into rear locating part 170 and the place ahead locating part 180.Namely, rear locating part 170 plays with the place ahead locating part 180 and makes chair 160 be stuck in the function of perpendicular rod 150.

This locating part 170,180 not only limits the rotation of chair 160, and is sitting under the state on the chair 160 when tilting forward and back the user, and chair 160 will wave between locating part 170,180, and swing is moved towards front and back gradually.

Namely, according to locating part 170,180 interval, the movement that can further increase chair 160 therefore according to user's hobby, when wanting more firmly to rock, is necessary to widen locating part 170,180 interval.Therefore rear locating part 170 is designed to removable pattern, and is provided with patchhole 190 in chair 160 sides, in order to fixing rear locating part 170.At this moment, for safety, rear locating part 170 can not break away from fully, therefore possesses the button (not shown) that touches mode dismounting rear locating part with single.

And, adorn the clamping projection (not shown) of carrying out lifting by button within it in the portion.And, according to swing 100 of the present invention, when the elderly takes chair 160 for the first time, as long as set foot on the sole of chair 160, can make chair 160 and perpendicular rod 150 mobile towards the rear because being applied to the load on the sole, thereby the elderly is not easy to take.

Therefore, install and fix rope 200 at support 110, and fix this static line 200 at perpendicular rod 150, thereby even apply load to sole, chair 160 can not move at the rear yet, thereby can take swing safely.One end of this static line 200 is installed in the support 110 that is positioned at chair 160 seat direction the place aheads, and the other end optionally hangs on the hook 210 that forms on the perpendicular rod 150 or from hook 210 and unclamps.Therefore tangle static line 200 in the time of will being sitting in swing and fix, and then unclamp static line 200 after taking, thereby can freely use.

And static line 200 can conveniently can not use the user of legs and feet or the elderly of strength deficiency to rock swing with pulling rope.

The court that following schematic illustration constitutes as previously mentioned tilts forward and back chair and the movement technique of the swing 100 that sways.

Fig. 3 to Fig. 7 shows that court according to the present invention tilts forward and back the side view of the motion principle of the swing that chair sways.

After the user takes chair 160 under the peacetime state of Fig. 2, apply strength towards the backrest side, just chair 160 rolls tiltedly backwards as shown in Figure 3.Chair 160 rolls tiltedly backwards like this, and perpendicular rod 150 will be close to the place ahead locating part 180, originally keeps perpendicular excellent 150 center of gravity hypsokinesis of balance in the vertical direction, as shown in Figure 4, erects excellent 150 and will rotate towards the place ahead.

As shown in Figure 5, so under the state that swing rotates towards the place ahead, for side shifting swing backwards again, weaken the power that backrest is applied, and on sole the application of force, chair 160 square neck forward is oblique, on 150 contacts of perpendicular rod rear locating part 170, the center of gravity of perpendicular rod 150 leans forward accordingly.Therefore, swing as shown in Figure 6, perpendicular rod 150 rotates towards rear direction.

Because foregoing effect, the back and forth movement of swing forms a circulation, as shown in Figure 7, the application of force on back and the chair that tilts backwards, then hypsokinesis of center of gravity, swing rotates towards the place ahead, if the movement of application of force swing will strengthen gradually again.

As above be illustrated with reference to preferential embodiment of the present invention, but the skilled worker of affiliated technical field can carry out various modification and change for the present invention in not exceeding the thought of putting down in writing in the patent claims of the present invention and field.
