The fixing bracket 25 is a member fixed by welding to the rear of the support frame 21 , and supports the horizontal shaft 26 axially in a state where the two are spaced apart from each other. Both ends of the horizontal shaft 26 are supported by the fixing brackets, and the horizontal shaft 26 is maintained horizontally at the rear of the pedestal.

The rotating body 31 is formed by bending a metal plate having a T-shape, and the central portion is coupled to the horizontal shaft 26 . The coupling method of the rotating body 31 with respect to the horizontal shaft 26 may vary. The rotating body 31 is rotatable using the horizontal shaft 26 as a rotation center axis.

The upper end of the rotating body 31 is inserted and fixed in the receiving space 41a of the cover body 41 as an insert plate 31a. The insert plate 31a and the cover body 41 can be disassembled. The cover body 41 can be replaced. A plurality of covers 40 to which various designs are applied or other pictures are drawn, the cover 40 can be replaced and operated. A wire connection part 31e is positioned at the lower end of the rotating body 31 . The wire connecting portion 31e is a portion in which one end of a tensile wire 56 to be described later continues.

The cover 40, in a state coupled with the insert plate 31a, rotates downward according to the rotational movement of the rotating body to cover the seat or rotates upward to cover the backrest. 8 is a state in which the cover 40 covers the seat 13 , and FIG. 9 is a state in which the backrest 15 is covered. Of course, the cover 40 has a larger area than the seat and backrest.

The cover 40 is composed of a hollow cover body 41 and an elastic pad 45 coupled to the cover body 41 . The cover body 41 is a hollow square plate made of synthetic resin or wood, and has an accommodation space 41a on one side. The accommodation space 41a is a groove into which the insert plate 31a described above is fitted. Reference numeral 41c denotes a space part. Since the space portion 41c is applied to the cover body 41, the weight of the cover body 41 is light by that much.

The elastic pad 45 is an elastic member of a certain thickness fixed to one side of the cover body 41 , that is, the surface facing the seat 13 . The elastic pad 45 may be a rubber plate or a waterproof sponge plate. As shown in FIG. 8 , the elastic pad 45 protects the seat 13 in a state in close contact with the upper surface of the seat 13 . In addition, as shown in FIG. 9 , a cushion is provided on the user's back in a state leaning on the backrest 15 .

The lifting unit rotates the cover 40 upward in the direction of the arrow b, and includes the housing 51, the pressing block 53, the horizontal bar 22, the first and second pulleys 54 and 55, and the tension wire 56. includes

The housing 51 is a box-shaped member installed in the center lower portion of the pedestal and has a vertical slit 51b on the front side. The vertical slit (51b) has a certain width and guides the lifting movement of the pressing block (53) as a vertically extended gap. In addition, as shown in Figure 4, the guide groove (51c) is formed in the inward surface of the vertical slit (51b). The guide groove 51c accommodates the slider 53a of the pressing block 53 .

In addition, a power source 57 is provided inside the housing 51 . The power source 57 is a rechargeable battery, and may be charged by receiving power supplied from the external solar module 59 . The photovoltaic module 59 is an existing facility located in the vicinity of a park or a walking path.

The pressing block 53 is a member mounted so as to be able to move up and down in the vertical slit 51b, and is partially exposed to the front of the housing. The reason why a part of the pressing block 53 is exposed to the front of the housing is to step down the pressing block 53 with a foot, as shown in FIG. 8 . When the pressing block 53 is lowered by stepping on it, the tension wire 56 is tensioned in the direction of the arrow g, and the cover 40 rotates upward.

Sliders 53a are provided on both sides of the push block 53 . The slider 53a guides the lifting motion of the pressing block 53 while being inserted into the guide groove 51c. In addition, a ring (53c) is provided at the rear of the pressing block (53). The ring 53c is coupled to the other end of the tension wire 56 .

The horizontal bar 22 is a rod-shaped member fixed by welding to the lower portion of the support frame 21, and extends horizontally in a direction perpendicular to the horizontal shaft. The horizontal bar 22 is accommodated in the inner space of the housing 51 .

In addition, the tensile wire 56 is a member made of a steel wire, one end is fixed to the wire connection part 31e, the lower part of the first pulley 54 and the upper part of the second pulley 55 , and the other end is a ring (53c) is connected. The tension wire 56 is tensioned when the pressing block descends in the arrow a direction to rotate the rotating body 31 in the arrow f direction. Of course, as the rotating body 31 rotates in the arrow f direction, the cover 40 rotates upward toward the backrest 15 .

On the other hand, the cover pushing unit 60 pushes the cover 40 leaning on the backrest 15 in the arrow d direction of FIG. 6 , so that the cover 40 rotates downward toward the seat 13 . The cover 40 is pushed by the cover pushing unit 60 and erected vertically, and then descends to the pedestal 13 side by the action of gravity. The cover pushing unit 60 is connected to the weight sensor 24 and operates when the weight of the user is not detected on the pedestal.

The cover pushing unit 60 includes a case 61 , a pushing arm 63 , a motor 65 , a rotary finger 66 , a wireless communication unit 67 , and a control unit 68 .

The case 61 is fixed to the rear surface of the backrest 15 and has an opening 61a on one side. A support pin 62 is fixed to the opening 61a. The support pin 62 serves as a rotation shaft that rotatably supports the pushing arm 63 . The central axis of the support pin 62 is equal to the angle of the backrest. That is, it is inclined by an angle θ with respect to the vertical line.

In addition, a stopper 61c is provided outside the opening 61a. The stopper 61c prevents the pushing arm 63 from sagging in the arrow k direction. By means of the stopper 61c, the pressure roller 63a is positioned in the gap 15a (when the cover pushing unit is in a standby state) and waits for the operation of the cover pushing unit.

The control unit 68 transmits the electric power applied from the power source 57 to the motor 65 to rotate the motor 65 . The rotation speed and rotation speed of the motor 65 are determined by the motor 65 . In addition, the wireless communication unit 67 is connected to the control unit 68 and transmits the operation status of the control unit 68 to the external manager 71 or transmits a signal received from the manager 71 to the control unit 68 . It is possible to control the motor 65 by a wireless communication method from a remote location.

The pushing arm 63 is a member extending in the longitudinal direction and having a curved shape, and includes an extension part 63b and a power transmission part 63c. The extension portion 63b is a portion extending to the outside of the case 61 with respect to the support pin 62 and has a pressing roller 63a at the extension end thereof. The pressure roller 63a is rotatable while supported by the extension part 63b. The power transmission unit 63c is a portion extending inside the case 61 with respect to the support pin 62 .

The motor 65 outputs a rotational force by electric power supplied from the power source 57, and has a rotary finger 66 on the drive shaft 65a. The drive shaft 65a and the support pin 62 are parallel. The rotary finger 66 rotates in the direction of the arrow m by driving the motor 65 and pushes the power transmission unit 63c in the direction of the arrow n.

The pushing arm 63 rotates clockwise by the rotary finger 66 and moves the cover 40 in the arrow d direction. The cover 40 is pushed by the pushing arm 63 and spreads from the backrest 15 , then tilts forward over the vertical line V and descends toward the seat 13 .

8 and 9 are views for explaining an operation method of the bench 10 provided with a cover for preventing contamination according to an embodiment of the present invention.

First, as shown in FIG. 8 , in a state in which the cover 40 covers the pedestal 13 , (in order to use the bench 10 ) the user steps on the pressing block 53 with their feet to descend. As the pressing block 53 descends in the arrow a direction, the tension wire 56 is tensioned in the arrow g direction and pulls the wire connection part 31e.

As the wire connection part 31e is pulled, the rotating body 31 rotates in the arrow f direction and the cover 40 rotates upward and reaches the backrest 15 over the vertical line V. In this state, the user can sit on the exposed pedestal 13 and lean his back against the elastic pad 45 . At the same time, the weight sensor 24 senses an increase in the load and transmits the detected content to the control unit 68 .

When the user leaves the seat, the weight sensor 24 detects that the load is reduced and transmits the detected fact to the control unit 68 . The control unit 68 receiving the signal from the weight sensor 24 operates the motor 65 . As the motor 65 operates, the pushing arm 63 rotates and the cover 40 moves in the arrow d direction to rotate downward. While the cover 40 rotates downward, the rotating body 31 pulls the tension wire 56 rearward, and the pressing block 53 rises and returns to the initial position. When the user leaves the seat, the cover 40 automatically operates to cover the pedestal 13 .

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
