  Hereinafter, an embodiment of a deck chair adjusting structure according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an overall perspective view of a deck chair having a seat back portion showing an embodiment of the deck chair adjusting structure of the present invention, and FIG. 2 is a drive mechanism disposed on a base portion on the back side of the seating portion of FIG. FIG. 3 is a perspective view showing a link mechanism disposed on the side surface side of the seating portion of FIG. 1, FIG. 4 is a perspective view of the link mechanism, and FIG. 5 is a side view showing a driving state of the link mechanism. FIG. 6 is a schematic view showing a use state of the deck chair.

  In the figure, reference numeral 10 denotes a deck chair. The deck chair 10 includes a seating portion 1 provided with a stepping plate 4, a seat back 2 disposed at a rear end portion of the seating portion 1, and the seating portion 1. A pair of armrests 3, 3 disposed on the left and right sides and a base frame 5 disposed below the seating portion 1 are configured.

As shown in FIG. 2, one end of a hydraulic cylinder 51, which is a drive mechanism, and a double connecting rod seat 52 are pivotally mounted on the rear end side of the base frame 5, respectively.
The rotating lever 11 fixed to the front end portion of the double connecting rod seat 52 and the lower surface of the seating portion 1 is connected to the tip end portion of the hydraulic rod 511 so as to be interlocked with each other. The double connecting rod seat 52 is provided with a stay 521 to which the bottom end of the armrest 3 is fixed. Further, a saddle type link 41 as a link mechanism is provided on both sides of the stepping plate 4 (see FIGS. 3 and 4), and both moment arms 42 of the saddle type link 41 are respectively connected to the seat portion 1 and the armrest 3. It is being fixed to the lower end part. Further, the rear of both moment arms 42 is connected to the side or end of the seat back 2 by a T-shaped connecting rod 43.

With the above configuration, normally, when the hydraulic rod 511 contracts, the stay 521 is displaced downward as the armrest 3 is displaced downward (the front end of the double connecting rod seat 52 moves up and down as the hydraulic rod 511 expands and contracts. The seating part 1 is pulled backward. That is, when the hydraulic rod 511 contracts, a force for pulling the seating portion 1 rearward is generated via the rotation lever 11.
At this time, the seat back 2 falls backward due to the displacement of the T-shaped connecting rod 41. At this time, the distance between the two moment arms 42 becomes longer and the saddle type link 41 is pushed out.

  In the present invention, as shown in FIG. 5, a design is used in which the saddle type link 41 is controlled to be extended by opening both moment arms 42. Therefore, the foot plate 4 is pushed out so as to rotate upward, whereby the deck chair 10 is fully deployed and falls back. Therefore, the user can take a break with the deck chair 10 easily and enjoy the relaxation and comfort of the deck chair 10 (see FIG. 6).

  On the contrary, when the hydraulic rod 511 is pushed out, the seating portion 1 is interlocked and pushed forward, the armrest 3 is also restored upward, and the angle of the seat back 2 is also changed to the upright state, Return to sitting position. In addition, since the distance between the two moment arms 42 is also shortened in the foot plate 4, the saddle type link 41 is contracted, and the entire deck chair 10 is in a normal sitting posture state.

  Further, in the process in which the hydraulic rod 511 of the hydraulic cylinder 51 extends to the maximum, the front end portion of the double connecting rod seat 52 is pivotally attached to the hydraulic rod 511, so that the front end portion of the double connecting rod seat 52 is hydraulically connected. As the bar 511 is extended, the bar 511 is lifted upward to change its angle and tilt forward. Therefore, the armrest 3 fixed to the stay 521 is lifted and tilted forward. In this process, the seat 1 and the seat back 2 are connected to the armrest 3 via the moment arm 42 and the T-shaped connecting rod 43. The Further, since the pivoting lever 11 and the hydraulic rod 511 of the seating portion 1 are pivotally mounted so as to be interlocked with each other, the seating portion 1 and the seat back 2 together with the armrest 3 are raised and tilted forward, so that the deck chair The whole 10 is lifted and tilted forward.

  In the above state, the user can stand up without using power, and can use the deck chair 10 with peace of mind even for elderly people who are physically disabled.
