Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the appearance of the opening and closing control device according to the present invention, Figure 2 is an exploded perspective view of the floor structure including the bottom plate and the base of the opening and closing control device according to the present invention, see this Will be explained.

Opening and closing control device 100 according to the present invention is a steel door 101, the door frame 102 is rotatably connected to the door 101, and the rotating shaft connecting the door 101 and the door frame 102 ( 103, a bottom plate 110 having an area including a moving range of the door 101 and forming a bottom of the door 101, and a receiving space 121 covered by the bottom plate 110, and closed. And a first and second bevel gears 131 and 132, a horizontal frame 136, a lifting table 137, and a locking table 138 which are fixed to each other by being fixed to the base 120 and the accommodation space 121.

The base 120 includes a receiving space 121 having an upper surface opening, and the rotating protrusion 122 and the stopper 123 are formed in the receiving space 121.

The first bevel gear 131 is rotatably fixed to the rotary protrusion 122, and a groove line 131 a formed in an arc shape is formed on the bottom thereof to be engaged with the stopper 123. That is, the first bevel gear 131 rotates only within the range of the home line 131a.

In addition, the first bevel gear 131 is fixed to each other via the rotation protrusion 122 and the torsion spring (139). The torsion spring 139 allows the first bevel gear 131 to return to its original position by turning the first bevel gear 131 when the first bevel gear 131 receives no force from the outside, and in the present invention, the first bevel gear ( The initial position of the 131 is the position of the first bevel gear 131 in the state in which the door 101 is closed.

Therefore, when the first bevel gear 131 is returned to its original position, the cam 134 rotates while the second bevel gear 132 interlocked with the first bevel gear 131 rotates. ) Moves upwards to fill the locking groove 138a with the ridges 137a.

Subsequently, the rotating shaft 103 is inserted into the rotating hole 131b of the first bevel gear 131. At this time, a rubber friction material 135 is inserted between the rotation shaft 103 and the rotation hole 131b. That is, the outer circumferential surface of the rotating shaft 103 and the inner circumferential surface of the rotating hole 131b are connected to each other through the friction ruler 135. When the rotating shaft 103 rotates, the first bevel is driven by the friction force of the friction ruler 135. The gear 131 rotates.

Meanwhile, a plurality of second bevel gears 132 meshing with the first bevel gear 131 are disposed in the accommodation space 121, and the vertically placed rotary shaft 103 for rotating the first bevel gear 131 is provided. ) And a linkage 133 orthogonal to the second bevel gear 132 is connected. In addition, a cam 134 is disposed at the end of the linkage 133 so that the rotational force of the cam when the first bevel gear 131 rotates is passed through the second bevel gear 132 and the linkage 133. 134). In this case, a plurality of sets of the second bevel gear 132, the linkage band 133, and the cam 134 are arranged in a fan shape with the first bevel gear 131. This is to correspond with the platform 137 of the shape corresponding to the arc shape, which is the distal movement path of the door 101, from below for the platform 137 and the horizontal frame 136 and the hanger 138 It explains in detail.

The distal end of the door 101 moves in an arc above the bottom plate 110. Thus, the bottom plate 110 is cut along the movement path of the door 101 end to form a guide line 111 penetrating up and down, and the locking groove 138a at regular intervals in the guide line 111. Fix the formed hanger (138). Meanwhile, the platform 137 having a plurality of ridges 137a inserted into the locking groove 138a and moving up and down is engaged with the plurality of cams 134 via the horizontal frame 136 and the cams 134. 134) moves up and down according to the state. As a result, while the lifting platform 137 moves up and down, the ridge protrusion 137a fills or empties the locking groove 138a.

On the other hand, when the horizontal frame 136 is engaged with the cam 134 is spaced apart from each other, the power is evenly distributed throughout the hanger 138 to support the hanger 138 to move up and down horizontally.

Figure 3 is a partial cross-sectional view showing the operation of the platform according to the present invention, will be described with reference to this.

As shown, the center of rotation of the cam 134 is located eccentrically, the rotation center is engaged with the linkage 133. That is, the rotation of the linkage 133 causes the outer circumferential surface of the cam 134 to move up and down to move the horizontal frame 136 supported on the upper surface of the cam 134 up and down. Of course, the lifting platform 137 uniformly supported by the horizontal frame 136 is also moved up and down, and eventually, the plurality of recesses 137a protruding from the lifting platform 137 are the locking grooves ( Withdraw into 138a).

On the other hand, a groove 106 is formed on the distal bottom surface of the door 101, and the engaging bar 107 is fixed to the groove 106 to be movable up and down. The catching bar 107 is fixedly disposed in the groove 106 via a ball spring 108 that is fixed so as not to fall below a predetermined height, as shown in FIG. ) Is inserted into the locking groove 138a, the locking bar 107 does not enter into the locking groove 138a. Therefore, the door 101 can be opened and closed by moving smoothly without engaging the engaging bar 107 and the locking groove 138a.

On the other hand, as shown in Fig. 3 (b), when the doldol 137a is moved downwards by the rotation of the cam 134, the doldol 137a that was filling the locking groove 138a is also caught while moving downward The groove 138a is emptied. Therefore, the locking bar 107 is moved downward by the elastic force of the ball spring 108 is inserted into the locking groove (138a). Of course, the insertion into the locking groove 138a of the locking bar 107 may prevent the door 101 from moving in the right direction and prevent the door 101 from closing by itself. On the other hand, one side of the lower end of the locking bar 107 forms an inclined surface 107a, so that the door 101 can be moved in one direction even if the locking groove 138a is in the same state as in FIG. .

This is to open the door 101 even if the opening and closing control device 100 according to the present invention in the state of FIG.

Figure 4 is an exploded perspective view showing the operation means connected to the rotary shaft according to the present invention, Figure 5 is an exploded perspective view showing the appearance of the operation means according to the present invention, Figure 6 of the operation means according to the present invention It is a perspective view showing the operation, it will be described with reference to this.

As described above, a lower end of the rotating shaft 103 for rotatably fixing the door 101 is engaged with the first bevel gear 131 and disposed vertically along the door 101.

Accordingly, the rotational force received when the door 101 is opened and closed is transmitted to the rotation shaft 103, so that the first bevel gear 131 also rotates along the rotational direction of the door 101. In this case, the rotation range of the first bevel gear 131 is limited by the home line 131a and the stopper 123. Therefore, the first bevel gear 131 and the rotating shaft 103 is a structure that receives a force by the friction force of the friction member 135, the first bevel gear through the groove line 131a and the stopper 123 When the door 101 is rotated beyond the rotation range of 131, the rotating shaft 103 is separated from the first bevel gear 131 to rotate.

Opening and closing control device 100 according to the present invention should be able to close as the conventional door when the adult opens the door 101. Therefore, the operation means 140 is placed at the position of the door 101 according to the height of the adult, and when the adult opens the door 101 while operating the operation means 140, the platform 137 moves downward. The state of FIG. 3 (a) can be maintained without moving. Of course, when a child who cannot operate the operation means 140 according to the height of the adult opens the door, the state of FIG. 3 (b) is opened when the door 101 is opened, and the door 101 is not closed again. To allow children to enter and exit safely. After the adult as a guardian manipulates the operation means 140, the force applied to the first bevel gear 131 is extinguished and returned to the initial position by the elastic force of the torsion spring 139, and finally the locking The groove 138a is filled by the bubbling part 137a so that the locking bar 107 of the door 101 can slide on the upper surface of the locking table 138 without being caught by the locking groove 138a.

On the other hand, the operation means 140 manipulated by an adult to dissipate the force applied to the first bevel gear 131 has the following structure.

The rotary shafts 103 and 103 ′ have locking grooves 104 and 104 ′ that horizontally penetrate, and are separated into upper and lower portions based on a height at which the operation means 140 is located. Therefore, the locking groove 104 and the locking groove 104 'are separated from each other, as shown in Figs. 6 (a) and 6 (b), respectively, according to the position of the operation means 140, the upper rotary shaft ( 103 ') and the lower axis of rotation 103 can move together or independently.

5 will be described in more detail the operation means 140 according to the present invention.

The linker 148 of the operation means 140 according to the present invention passes through the engaging grooves 104 and 104 'while moving in the horizontal direction as shown in FIG. Therefore, the horizontal movement of the linker 148 should be selectively adjustable. For this purpose, the operation means 140 according to the present invention is mounted in the door 101 and the upper and lower cases 142 and 142 ', the front and rear cases. 143 and 143 'and the enclosure surrounded by the first and second pressing members 141 and 141'.

Here, the first and second pressing members 141 and 141 'may move horizontally, even if pressure is applied to one of the first and second pressing members 141 and 141'. First and second levers 141a and 141a 'are formed on the first and second pressing members 141 and 141', respectively, so that the first and second pressing members 141 and 141 'are horizontally moved. ) Is formed with a pinion 141b which rotates in engagement with the first and second legs 141a and 141a ', respectively. Meanwhile, the first and second pressing members 141 and 141 'are connected to interlock with each other via connecting rods 141c and 141c', and the connecting rods 141c and 141c 'may be engaged and fixed by a piston method. When the carcasses 141e and 141e 'are inserted into the connecting rods 141c' corresponding to the cylinders, the carcasses 141e and 141e 'are extinguished by pressure on the first and second pressing members 141 and 141'. ) To push the first and second pressing members (141, 141 ').

As a result, when an adult presses one of the first and second pressing members 141 and 141 ', the first lever connected to the pressing member rotates horizontally while the pinion rotates, and the pinion is engaged with the second second leg of the other side. Apply horizontal force to the second leg.

Subsequently, coarse cylinders 144 and 144 'and coarse pistons 145 and 145' are connected to the first and second pressing members 141 and 141 ', respectively. When the pressure is narrowed under pressure, the main pistons 145 and 145 'increase the internal pressure of the main cylinders 144 and 144'.

The rear case 143 has a through hole 143b through which the linker 148 penetrates and moves horizontally, and a driven cylinder 146 communicating with the main cylinders 144 and 144 'is disposed. . In addition, a driven piston 147 that engages the driven cylinder 146 is fixed to the linker 148. Therefore, the movement of the driven piston 147 horizontally moving along the driven cylinder 146 causes the horizontal movement of the linker 148.

As a result, when the first and second pressing members 141 and 141 'are pressurized and engaged with the main pistons 145 and 145' to increase the internal pressure of the main cylinders 144 and 144 ', the main cylinder Air or oil filled in 144 and 144 'flows into the driven cylinder 146 to push the driven piston 147. At this time, the volume of the driven cylinder (144, 144 ') is larger than the volume of the driven cylinder (146) driven piston 147 engaged with the driven cylinder 146 even with a small movement of the driven cylinder (144, 144') Moves greatly.

On the other hand, when the pressure is extinguished on the first and second pressing members 141 and 141 ', the first and second pressing members are pressed by the elastic force of the first elastic bodies 141e and 141e' fitted to the connecting rods 141c and 141c '. The member 141, 141 ′ is pushed out, and at the same time, the second elastic body 148a formed at the end of the linker 148 pushes the front case 143 ′ and the linker 148 while the driven piece tone ( 147 to apply pressure to the driven cylinder 146. As a result, the internal pressure of the driven cylinder 146 rises, and while the internal pressure of the main cylinders 144 and 144 'is lowered, the return of the first and second pressing members 141 and 141' to the initial position is of course discharged. The air or oil in the main cylinders (144, 144 ') is also refilled.

Meanwhile, guide grooves 141d are formed at both edges of the first and second pressing members 141 and 141 'to smooth the horizontal movement of the first and second pressing members 141 and 141'. A guide protrusion 143a is formed on the inner surface of the front and rear case 143 and 143 'which is in contact with the guide groove 141d.

Therefore, the opening and closing control device 100 according to the present invention operates in the following process.

When the child exerts a force on the door 101 without manipulation of the operation means 140 to open the door 101 of the opening and closing control device 100 according to the present invention, the rotary shaft 103 along the door 101 is In this case, the linker 148 is engaged with all the engaging grooves 104 formed on the upper and lower rotary shafts 103 and 103 ', respectively, so that the upper rotary shaft 103' and the lower rotary shaft 103 interlock with each other. Therefore, when the upper rotating shaft 103 'rotates together with the door 101, the lower rotating shaft 103 also rotates to transmit the rotational force to the first bevel gear 131, and through the above-described process, the locking groove The engaging bar 107 of the door 101 is inserted into 138a to stop the door 101 from closing.

On the other hand, when an adult presses the door 101 while pressing the first and second pressing members 141 and 141 'of the operation means 140, the linker (operation) having the above-described structure operates the linker ( 148 is horizontally moved away from the engaging grooves 104 and 104 ', thereby separating the upper rotary shaft 103' and the lower rotary shaft 103 from each other. Therefore, when the adult pushes the door 101 and rotates, only the upper rotating shaft 103 'is rotated and the lower rotating shaft 103 is stopped so that the first bevel gear 131 does not rotate. Therefore, the locking groove 138a is filled by the ridges 137a so that the locking bar 107 is not inserted into the locking groove 138a, and the door 101 can rotate without interference.

The drawing number "112", which has not been described, is a cover and closes the receiving space 121 opened together with the bottom plate 110.
