The operation of an apparatus for lifting and lowering the kitchen utensils according to the first through third embodiments of the present invention.
First, the apparatus for lifting and lowering the kitchen utensils according to a first embodiment of the present invention does not use an additional locking and unlocking apparatus, but lifts or lowers the kitchen utensils by an elastic force of the plate shaped spring or stops the same at a certain position. As shown in Figures 2A and 2B, in the kitchen utensils 200, the engaging groove(not shown) fomied in the back surface is engaged by the hook shaped engaging plate 22 of the driving plate 20 for thereby being engaged to the driving plate 20. In the plate shaped coil spring 42 of the lifting and lowering suspension apparatus 40 which is wound on the roller 41, the fixing plate maintains a balance at a certain position. When a user uses an electric grill G of the kitchen utensils 200, the user pulls the handle 210 in the downward direction of the fixing plate, the plate shaped coil spring 42 of the lifting and lowering suspension apparatus 40 is unwound from the roller 41, so that a certain balance is obtained between the elastic force of the coil spring and the weight of the kitchen utensils at a certain position that the user wants. Therefore, the kitchen utensils 200 is fixed. Here, the guide rail 30 installed between the brackets 211 and 21 of the fixing plate
10 and the driving plate 20 guides the kitchen utensils for being smoothly sled. Since the bearings 33 are disposed in the bent portions which are opposite to each other in both sides of the outer rail 31 and the inner rail 32, the kitchen utensils smoothly slides by the bearings. The outer rail and the inner rail operate as the bracket(double bracket function) for guiding the lifting and lowering weight together with the bracket and for supporting the weight.
Therefore, when the user lowers the kitchen utensil at a desired position and releases the handle, the plate shaped spring 42 implements a balance between the weight of the kitchen utensil 200 and the elastic force thereof for thereby maintaining the kitchen utensil at the position.
In order to move the kitchen utensil which is at a certain position to the origin position(for example, the uppermost position), the user pulls down a little the handle of the kitchen utensils and then releases in the upward direction, so that the kitchen utensil returns to its original position. Therefore, the lifting and lowering apparatus of the kitchen utensil according to the present invention is capable of easily adjusting the position of the kitchen utensil by the user without using an additional fixing unit, hi addition, since the kitchen utensil such as an electric oven is installed together with the hood, it is possible to fully discharge a gas from the food when the food is cooked and a gas from the kitchen utensils to the outside. The lifting and lowering apparatus of the kitchen utensils according to a first embodiment of the present invention does not use an additional fixing unit, the plate shaped coil spring which corresponds to the weight of the kitchen utensils which is changed based on the size and type of the kitchen utensils must be changed.
In order to overcome the above problems, in the second embodiment of the present invention, a certain fixing unit is further provided. The operation of the lifting and lowering apparatus of the kitchen utensils according to the second embodiment of the present invention will be explained.
As shown in Figures 3 through 5 and Figures 7A through 7C, in order to prevent the kitchen utensil from being upwardly moved by the plate shaped coil spring, a stopper 60 additionally installed in the fixing plate controls the lifting and lowering operation of the kitchen utensils.
Since one end of the engaging portion 61 hinged to the stopper bracket 63 fixed to the driving plate 20 by the stopper pin 64 is engaged to the toothed portion 51 of the stopper bar 50 fixed to the fixing plate 10, the kitchen utensils 200 which is moved together with the driving plate 20 is positioned at the uppermost portion or a certain portion of the fixing plate 10. Here, the stopper pin is installed together with the torsion spring 65 and operates by an elastic force of the torsion spring.
The other end of the engaging portion 61 is connected with the action wire 62. Therefore, when the user pulls the action wire 62, the engaging portion 61 compresses the torsion spring 654, and one end of the same is disconnected from the toothed portion, so that the user moves the kitchen utensil in the upward or downward directions by holding the handle of the kitchen utensils. Next, when the kitchen utensils is positioned at a certain position that the user wants, the user releases the force for pulling the action wire 62, and the engaging portion 61 is moved to the toothed portion by the torsion spring 65. Since one end of the engaging portion is engaged with the toothed portion, the kitchen utensils is stopped at a certain position that the user wants.
Here, a unit for pulling and releasing the action wire 62 may be implemented by a certain known member.
A unit for pulling and releasing the action wire 62 according to the present invention may be installed in the interior of the handle pipe of the kitchen utensils. The operation of the same will be explained with reference to Figures 7A through 7C.
As shown in Figure 7A, if the action wire 62 is not pulled, the slider 78 fixed to the end of the action wire 62 does not contact with the first end cap 73 by the slider spring 77. When the user pushes the knob 79 vertically engaged to the slider 79, the slider 78 is guided by the tap rod 75 and is moved in the direction in which the slide spring 77 is compressed, and the action wire 62 is pulled for thereby moving the kitchen utensil according to the first and second embodiment of the present invention.
Here, the slide knob support member 76 may be fixed in the interior of the pipe 72 in the Icnown method.

Here, the operation of the lifting and lowering apparatus of the kitchen utensil according to the fourth through sixth embodiments of the present invention will be explained.
First, the lifting and lowering apparatus of the kitchen utensils according to the fourth embodiment of the present invention does not use an additional locking and unlocking apparatus and does not use an additional locking and unlocking apparatus after the lifting and lowering operation and lifts or stops the kitchen utensils at a certain position by the elastic force of the gas spring.
As shown in Figures 8A and 8B, in the kitchen utensils 200, an engaging groove(not shown) fomied in the back surface of the same is engaged with the hook shaped engaging plate 22 of the driving plate 20 for thereby being fixed to the driving plate. The gas spring 40 A is installed between the bent flanges 10F and 20F of the fixing plate 10 and the driving plate 20. As the driving plate 20 is lifted and lowered, the length of the gas spring 40A is increased and decreased for thereby maintaining a balance with respect to the kitchen utensils, and the kitchen utensils is stopped with the changed length or at a certain position. When the user pulls down the handle 210 of the kitchen utensils 200 for using the electric grill G of the kitchen utensils 200, the kitchen utensils 200 fixed to the driving plate 20 is downwardly moved below the fixing plate 10 as the body and rod of the gas spring 40A are escaped, so that the kitchen utensil 200 is fixed at a certain position that the user wants. At this time, the elastic force of the gas spring 40A is balanced with the weight of the kitchen utensil based on the changed length of the gas spring 40A. The guide rail 30 installed between the brackets 11 and 21 of the fixing plate 10 and the driving plate 20 guides the kitchen utensils for a smooth downward movement. Since the bearings 33 are inserted in the bent portions which are fomied opposite to each other at both sides of the outer rail 31 and the inner rail 32, the kitchen utensils are smoothly lifted or lowered based on the bearings. In addition, the outer rail and the inner rail operate as the bracket(double bracket function) which guides the lifting and lowering operations together with the bracket and supports the weight of the same.
Therefore, when the user lifts or lowers the kitchen utensils at a certain position that the user wants and then releases the handle, the gas spring 40A implements a balance between the weight of the kitchen utensils 200 and the elastic force of the same at the position in which the kitchen utensils 200 is stopped, so that the kitchen utensils is stopped at the above position.
In order to move the kitchen utensils from a certain position to an original position(for example, the uppermost position), the handle of the kitchen utensils is held and pulled down a little and then released, so that the kitchen utensils is retumed to the original position.
Therefore, in the lifting and lowering apparatus of a kitchen utensils according to the present invention, it is possible to easily adjust the position of the kitchen utensils without using an additional fixing unit. In addition, since the kitchen utensils such as the electric oven is installed together with the hood, it is possible to fully discharge a gas of the food when the food is cooked and a gas from the kitchen utensils to the outside.
Since the lifting and lowering apparatus of the kitchen utensils according to a fourth embodiment of the present invention does not use an additional fixing unit, it is need to design the gas spring 40A which corresponds to the weight of the kitchen utensils which is changed based on the size and type of the kitchen utensils. In order to overcome the above problems, in a fifth embodiment of the present invention, a certain fixing unit is further provided. The operation of the lifting and lowering apparatus of a kitchen utensils according to the fifth embodiment of the present invention will be explained. As shown in Figures 9 through 11 and Figures 13A through 13C, in order to maintain the kitchen utensils at a certain position using the gas spring 40A, the stopper 60 installed in the fixing plate controls the lifting and lowering operation of the kitchen utensils like the second embodiment of the present invention.
Since one end of the engaging portion 61 which is hinged to the stopper bracket 63 fixed to the driving plate 20 by the stopper pin 64 is engaged to the toothed portion 51 of the stopper bar 50 fixed to the fixing plate 10, the kitchen utensils 200 which is moved together with the driving plate 20 is stopped at the uppermost position or at a certain position. Here, the stopper pin is installed together with the torsion spring 65 and operates by an elastic force of the torsion spring. The other end of the engaging portion 61 is connected with the action wire 62.
Therefore, as shown in Figures 13A through 13C, when the user turns the knob 65 and then pulls the action wire 62, the engaging portion 61 compresses the torsion spring 65, and one end of the same is disconnected from the toothed portion. The user holds the handle and moves the kitchen utensils in the upward or downward direction. When the kitchen utensils is positioned at a position that the user wants, the user releases the action wire 62, and the engaging portion 61 is moved to the toothed portion by the torsion spring 65. One end of the engaging portion is engaged with the toothed portion 51, the kitchen utensils is positioned at a certain position that the user wants.
As shown in Figures 13A through 13C, the unit for pulling and releasing the action wire 62 according to the present invention is the knob apparatus 70A installed in the front surface of the kitchen utensils. The operation of the same will be explained.
First, when the user turns the knob 71 A, the ball spring 73 A installed in the fixing portion 75 A enables a smooth rotation of the rotation plate 78 A on the fixing plate 75 A. At this time, the rotation angle of the rotation plate is limited and stopped by the engaging shoulder portion 75. Therefore, when the knob is rotated by the rotation angle that the user wants, the action wire cable 62-1 is moved from the toothed portion by the length corresponding to the circular of the rotation of the knob.
Therefore, when the action wire cable 62-1 is moved to the knob apparatus, the end of the engaging portion fixed to the toothed portion is disconnected from the toothed portion. The kitchen utensils 200 fixed to the driving plate 20 is lifted and lowered with respect to the fixing plate 10 based on the elastic force of the gas spring 40A. When the kitchen utensils 200 is moved to the position that the user wants, the knot is retumed to the original position. The end of the engaging portion is fixed to the toothed portion, and the kitchen utensils is fixed at the above position.
