BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door opening device of a furniture to which a basket can be attached,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing device for furniture, and more particularly to a hinging device to which a basket capable of holding objects can be attached.

It would be very convenient and space-efficient to be able to place objects inside furniture, such as a tea table, which are not typically used for storage and storage. FIG. 1 is a perspective view showing a door opening / closing device roll capable of placing an object on a basket attached to the door when the door is opened. FIGS. 2 (a) and 2 (b) Shows a perspective view of the door opener of the time.

As shown in the drawing, the known hinge device 1 is provided with a plate-like first bracket 10 fixed to a car table, that is, the inner side wall 5 of the furniture 3, with screws or the like passing through the grooves 11 and 11 ' And a plate-like second bracket 15 having a folded door fixing portion 17 so as to be fixed to the door 6 of the furniture. The folded door fixing portion 17 is provided with a binding portion 19 to which the basket 7 can be attached. The second bracket 15 has a first bracket 15 and a second bracket 15 so as to be rotatable about a predetermined angle with respect to the first bracket 10 by the rotation of the first crank 20 and the second crank 22 bent in a V- And is coupled with the bracket 10. That is, the first crank 20 has a rotating shaft 30 positioned in the second bracket 15 and a rotating shaft 31 positioned in the first bracket 10, and the second crank 22 has a rotating shaft 30 positioned in the second bracket 15, And a rotary shaft 34 positioned on one side of the air cylinder 25 is provided on the other side of the rotary shaft 32 positioned in the second bracket 15 on one side of the rotary shaft 33 located in the V- . The air cylinder 25 includes a main body 26 and a reciprocating piston 27. A first connecting member 28 is provided on one side of the main body 26 and a second connecting member 29 is provided on an end of the piston 26 . Described rotation shaft 34 is located in the second linking member 29. [ On the other hand, the first linking member 28 has a rotation shaft 35 positioned in the first bracket 10. All of the rotating shafts can be made in any manner that allows them to rotate axially, such as in a bolt-nut fashion, and the rotating shafts shown are made of rivets.

Referring to Figure 2 (a), which shows the hinged device 1 when the door 6 of the furniture is in the closed position, the first crank 20 and the second crank 22, It can be seen that the first crankshaft 34 and the second crankshaft 31 are adjacent to each other. When the door 6 is now pulled in the direction of arrow A to open the door 6, the second crank 22 rotates about the rotational axis 33 of the bent portion in the direction opposite to the arrow A, 34 and the rotary shaft 31 of the second crank move away from each other. At this time, the piston 27 is drawn out by a predetermined length while the air cylinder 25 rotates counterclockwise about the rotation shaft 35, and the two rotation shafts 30 and 32 located on the second bracket are rotated by the first bracket 10) Rotate axially from the inside to the outside and upwards. On the other hand, it can be seen that the two rotary shafts 30 and 32 mutually rotate in a relatively horizontal direction during the axial rotation. The rotary shafts 31, 33, 35 of the entire rotary shafts are fixed rotary shafts whose positions are not changed, and the rotary shafts 30, 32, 34 are movable rotary shafts whose positions are changed. Through such a complicated shaft rotation, the door 6 to which the second bracket 22 is attached is in the open position as shown in FIG. 2 (b).

Those skilled in the art will appreciate that the illustrated hinged device 1 and another hinged device having the same configuration as this device but having a mirror symmetrical arrangement should be fixed to the inner walls and doors of the furniture in pairs.

This known hinge device 1 has a problem that an expensive air cylinder 25 is used. In particular, the smaller the size of the air cylinder, the higher the price. The size of the air cylinders commonly used for the hinged devices is about 10 cm, which is an absolute part of the total cost of the hinging device. Furthermore, since the cylinder 25 used in the hinge device 1 is required to have the connecting members 28 and 29 at both ends thereof, there is a problem that the cost is further increased.

The object of the present invention is to solve the above-mentioned problem of the known door-opening device, and it is an object of the present invention to provide a door-opening device which is simple in structure without using an expensive air cylinder.

In order to accomplish the above object, the present invention provides a refrigerator comprising a first plate-shaped bracket fixed to the inside of a furniture, and a plate-shaped second bracket having a basket fixing portion and a bent cranked fixing portion and fixed to the door, A door of a furniture to which a conventional basket can be attached so that the second bracket can be axially rotated at a constant angle with respect to the first bracket by the mutual axial rotation of the linear crank and the V-shaped crank axially rotatably fixed to the bracket, The hysteresis device was modified as follows so that the air cylinder is not necessary.

The two ends of the linear crank are rotatably fixed to the first bracket and the second bracket, respectively, and the V-shaped crank is spaced apart from the linear crank by a predetermined distance, so that both ends of the V- The end portion of the first bracket is rotatably fixed to the first bracket, and the end portion of the first bracket is axially rotatably fixed to the first bracket. The end portion of the first bracket is axially rotatably fixed to the first bracket through the elastic rotation shaft portion .

The elastic rotation shaft portion includes a first spring support portion having one end fixed to the first bracket so as to be rotatable about the axis of the first bracket, a second spring support portion having one end fixed to one end of the V- As shown in Fig.

And a spring support rod into which the first spring support portion and the second spring support portion are inserted. It is also preferable that the first and second spring supports have a pair of guards located on both sides of the spring support rod.

Referring to Figs. 3 and 4 showing one direction and the opposite direction of the hinge according to the present invention, the hinge device 1 'of the present invention is similar to the conventional hinge device 1 in that a plate- 1 bracket 40 and a plate-like second bracket 50 fixed to a door of a furniture and having a basket binding portion 55. The first bracket 40 and the second bracket 50 are rotatable about an axis So that the second bracket 50 can rotate about the first bracket 40 at a constant angle by the mutual axial rotation of the linear crank 60 fixed to the first bracket 40 and the crank 70 bent in the V shape. The basic operation of mutual axial rotation between the first bracket 40 and the second bracket 50 by the linear crank 60 and the V-shaped crank 70 in the hinge 1 'according to the present invention, (1). However, unlike the conventional hinging device 1 using an air cylinder, the hinging device 1 'of the present invention has a large difference in that it adopts the elastic rotary shaft portion 80. These differences and other improvements will be described below.

3 to 5, the first bracket 40 is a plate-shaped body and is fixed to the side wall 5 (see FIG. 9) of the furniture 3. The first bracket body has a bracket section Quot; shaped < / RTI > The linear crank 60, the V-shaped crank 70 and the elastic rotary shaft 80 are positioned in the space in the bent portion 43 so that they can be protected by the main body of the first bracket 40, It is good for cosmetic view because it can not be seen from outside when installed. In order to fix the first bracket 40 to the side wall of the furniture, grooves 41 into which screws or the like are inserted are formed at appropriate positions along the bent portions 43 at appropriate positions.

The second bracket 50 is also formed of a plate-shaped body and is partially bent to form a crank-hooked portion 51. The second bracket 50 is attached to the door 6 (see FIG. 9) of the furniture, and a groove 53 into which a screw or the like is inserted is formed in an appropriate number of suitable positions of the bracket body. The main body of the second bracket (50) is formed with a basket binding part (55) to which a basket capable of holding objects can be attached. In the case of the hinge device 1 'according to the present invention, the basket stopper 57 is provided as another bent portion. The basket stopper 57 serves to block the movement of the basket 7 (see FIG. 9) attached to the basket binding portion 55, as it moves left and right while opening and closing the door of the furniture. In the illustrated embodiment, the basket stopper 57 is formed as a relatively large bend, but may be formed to have any configuration, e.g., a protrusion, that can serve as a bend or stopper of any suitable size.

The second bracket 50 is supported by the first bracket 40 by a shaft rotation of the V-shaped crank 70 and the linear crank 60. In this case, The first bracket 40 and the second bracket 40 are rotatable about their respective axes. More specifically, both ends of the linear crank 60 have rotary shafts 61 and 63 which are rotatably mounted on the first bracket 40 and the second bracket 50, respectively. The V-shaped crank 70 is fixed to the first bracket 40 and the second bracket 50 such that both ends of the V-shaped crank 70 are spaced apart from the linear crank 60 by a predetermined distance, The end fixed to the shaft rotatably is fixed to the first bracket 40 via an elastic rotary shaft 80, which will be described later. That is, the end portion of the V-shaped crank 70, which is rotatably fixed to the second bracket 50, has a rotation axis 73 that is directly rotatably fixed to the second bracket 50, but the first bracket 40 Is rotatably fixed to one side of an elastic rotary shaft portion 80 to be described later. The bent portion of the V-shaped crank 70 has a rotation axis 72 directly fixed to the first bracket 40 for pivotal rotation.

5, the rotating shaft 61 of the linear crank 60 is fixed to the first bracket 40, and a hollow rotary shaft portion 100 having a screw groove is screwed into the linear crank 60 (Not shown) and inserted into a hole 105 formed at one side end of the washer 107 with a washer 107 of a suitable height interposed therebetween. The rotary shaft portion 100 has a jaw 101 for allowing the linear crank 60 to be positioned. All the rotary shafts mentioned here are formed in the same manner, but the jaws 101 may not be formed or the heights of the rotary shafts 100 may be different if necessary. In addition, the rotation shaft may be formed by any method capable of rotating the shaft, for example, a rivet method, a bolt-nut method, or the like, in addition to the same method as the illustrated embodiment.

The opening and closing device 1 of the present invention is configured such that the end portion of the V-shaped crank 70 which is rotatably coupled to the first bracket 40 is connected to the first bracket 40 And the elastic rotary shaft portion 80 will be described in detail below.

The elastic rotary shaft portion 80 includes a first spring support portion 81 having a spring support rod 81 ', a second spring support portion 83 having a spring support rod 83', and spring support rods 81 ', 83', respectively. One end of the first spring support portion 81 has a rotation shaft 71 'which is rotatably fixed to the first bracket 40 and one end of the second spring support portion 83 is supported by the one end of the V- And has a rotary shaft 71 fixed as far as possible. Therefore, as described above, the end portion of the V-shaped crank 70 which is rotatably coupled to the first bracket 40 is not directly rotatably coupled to the first bracket 40, Is rotatably coupled to the first bracket 40 through the spring support portions 81 and 83 and a linear spring 85 supported by the spring support rods 81 'and 83' of the spring support portions 81 and 83 do. In the illustrated embodiment, the spring supports 81,83 of each straight member have a pair of guards 82,84 located on either side of the spring support rods 81 ', 83'. The guards 82 and 84 protect the spring 85 to prevent the spring from being disengaged from the first and second spring supporting portions 81 and 83 and damaging the spring 85 by an external impact or an external thing.

Hereinafter, the operation of the hinge apparatus 1 'according to the present invention will be described with reference to Figs.

6 is a view showing a state in which the door 6 (see Fig. 9) of the furniture is closed. The second bracket 50 fixed to the door 6 is not rotated about the first bracket 40 In the closed position. In this state, the V-shaped crank 70 is restricted in one direction by the first stopper 91 fixed to the main body of the first bracket 40, and the linear crank 60 and the V-shaped crank 70 are relatively In the vertical direction. Since the spring 85 of the elastic rotation shaft portion 80 is slightly longer than the straight line connecting the end portions of the spring support rods 81 'and 83' of the first and second springs 81 and 83, In the left-right direction.

In this state, when the door 6 of the furniture is pulled to the open position (that is, when the second bracket 50 is pivoted to the opening position of the door with respect to the first bracket 40) The linear crank 60 and the V-shaped crank 70 are axially rotated about the rotational shafts 61 and 72 while the rotational shafts 63, 71, (51). When the rotary shaft 71 of the V-shaped crank 70 rotates while moving, the second spring supporting portion 83 constituting the elastic rotary shaft portion 80 is arranged in a more vertical direction as shown, (85) is in a state of being relatively curved in a relatively linear state (Fig. 6). In this maximum curved state, some of the springs (more specifically, the spring portions located in the second spring support portions) are in the maximum compressed state. On the other hand, the first spring supporting part 81 moves only slightly counterclockwise to the extent that it does not move or revolve around the rotating shaft 71 '.

When the door 6 of the furniture is now pulled to the fully opened position (that is, when the second bracket 50 is pivoted to the fully opened position of the door with respect to the first bracket 40) The linear crank 60 and the V-shaped crank 70 are further rotated about the rotational shafts 61 and 72 so that the rotational shafts 63, 71, 51). This axial rotation continues until the other one-directional motion is restricted by the second stopper 93, where the V-shaped crank 70 is fixed to the main body of the first bracket 40. [ When the rotary shaft 71 of the V-shaped crank 70 is rotated while being rotated, the second spring support portion 83 constituting the elastic rotary shaft portion 80 maintains the vertical direction and the spring 85 Becomes a relatively linear state after a maximum curved state. At this time, the compressed spring portion is released in its maximum curved state. On the other hand, the first spring support portion 81 rotates about a rotation axis 71 'in a direction more perpendicular to the axis. The linear crank 60 and the V-shaped crank 70 are in a state of being aligned in a relatively horizontal direction, and the interval therebetween is also maximized.

The operation of the door 6 of the furniture from the fully opened state (state of FIG. 8) to the closed state (state of FIG. 6) proceeds in the reverse order of the steps described above. In the present invention, when the door of the furniture is pivoted from the open position to the closed position or from the closed position to the open position, when the spring 85 is moved from the most curved state to the relatively linear state, The shaft rotation proceeds by the elastic force. The elastic rotary shaft portion 60 used in the present invention may be positioned slightly lower left (in a state shown by a dotted line) with respect to a straight line connecting the rotary shaft 71.71 ', not the state shown by the solid line in FIG. 6, The operation in the state shown by the dotted line is also the same.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
