Description

Foldable Table Legs {FOLDABLE TABLE LEGS}

The present invention relates to a gyoza statue that is widely used in general homes, and more specifically, the upper leg that supports the grate plate on a certain height with respect to the floor surface is unfolded by simple operation when using gyoza statues to support it more stably. In the case of storage, it relates to a folding upper leg that provides a mobility and convenience of storage by folding the upper leg in a solid state.

In general, the gyoza statue has a short upper leg to suit the sedentary structure of Korean tradition, and there are various types of small to very large and heavy depending on its size.

In the case of small gyoza, there is no problem in the movement and storage in use, but the bulky and heavy gyoza is difficult to move and store in use.

Therefore, when using a bulky gyoza or a small gyoza phase, if you want to use the upper legs to spread, and when not using the gyosang statues are folded and commercialized a variety of methods to facilitate the movement and storage has been devised, For example, Republic of Korea Utility Model Publication No. 1998-020313 (name: foldable upper legs), the legs are coupled to the bottom edge of the top plate foldable, the sliding portion is formed at one end and the groove is formed below the sliding portion and predetermined A shaft is formed at a position formed on the upper end of the leg, and a guide portion corresponding to the sliding portion is formed along the curved surface and the shaft hole is formed to be coupled to the shaft is fixed to be mounted to the guide panel, and on one side end An elastic bias spring is coupled to the formed protrusion and the guide part is inserted into a predetermined position. A lock guide hole is formed to have the operating handle for moving up and down in the operating groove, and one side is axially coupled to the leg, the other side is fixed to a predetermined position inside the guide panel having a bracket for rotationally supporting the leg We offer folding upper legs.

This folding upper leg presses the operation knob installed on the sliding body with one hand after being used on the gasket and rotates in one direction while holding the leg with the other hand. By sliding along the guide part, the leg is folded inside the guide panel, and the operation handle is released from the fixing groove by the action of the spring by holding the folded leg and rotating it in one direction for using gyoza. By sliding the sliding portion along the guide portion of the fixture, the upper plate is supported in the unfolded state of the leg.

However, the folding upper legs are complicated in structure and the process of assembling the fixing body to the guide panel when assembling the upper leg to the lower part of the gasket, and the sliding body combined with the upper leg to the fixing body is complicated and cumbersome. As a result, the manual labor is increased, resulting in a decrease in productivity.

In addition to the inconvenience of having to hold the upper leg with one hand and press the operating handle with the other hand every time the upper leg is folded, there is no guidance that the upper leg can be moved reliably. It is pointed out that the structure that firmly secures the upper leg in a fully extended and folded state is not strong.

In addition, in Korean Utility Model Registration No. 331869 (name: upper leg folding structure), the upper leg was simply unfolded and folded without lifting or tightening the upper leg with the pivoting section by simply lifting and lowering the upper leg. Or when you want to fold, the upper leg is in contact with the support sphere to support the upper plate on the gallows, so the lifting and lowering movement of the upper leg is not smooth. As a result, the upper leg is held by one hand and the upper leg is held by the other hand. There is a problem in that it is not only difficult to push in a strong direction or pull out in a downward direction, but also the complexity of the structure of the upper and lower legs and the productivity is lowered as well as the unit price of the product increases.

Therefore, it is desirable to provide a gyoza image that can heal the above problems while lowering the gyoza image in terms of cost, and the grate image in which the gyoza legs can be folded more easily and quickly in terms of reliability and simple structure.

Accordingly, an object of the present invention is to provide a folding upper leg that allows the upper and lower legs to be more quickly and stably folded and folded by a simple left and right pivoting operation without inflicting force when folding the upper leg. The inner circumferential surface of the seat is coupled to the inner circumference and the upper outer circumferential surface of the upper leg forms a guide hook that projects vertically downward so that the left and right pivots can be pivotally coupled to the inner circumference of the left leg. When the upper leg is rotated in any one of the left and right directions around the left arm, the upper leg is rotated to its original position and vice versa.

Another object of the present invention is to provide a folding upper leg to support the gyoza more stably without shaking in the open state of the upper leg.

Another object of the present invention is to provide a folding leg to simplify the structure of the leg to contribute to the reduction of production cost.

Further objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

According to the folding upper leg according to the present invention for achieving the above objects, the hemispherical base is coupled to each corner of the bottom surface of the top plate and opened in one vertical direction and has a rotating space portion, and can be rotated without being separated from the base. In gyoza having upper legs folded and unfolded with respect to the seat;

The seat may include: first and second coupling guides formed by cutting vertically downward to face both upper ends of the rotating space part; First and second pivot support portions communicating with the first and second coupling guides, respectively, and cut and formed in a horizontal direction by a predetermined length with respect to the first and second coupling guides; And an inner portion that is rounded and cut by a predetermined length in a horizontal direction on a lower surface of the rotating space portion.

The upper leg is formed in the upper end of the rotating pivot between the cylindrical fitting fitted to the seat; A rotation pin penetrating through an upper end portion of the pivot support and inserted into the first and second coupling guides to move along the first and second pivot support portions; And projected downwardly on the outer peripheral surface of the lower end of the pivot support to be inserted and moved into the inner portion during the expansion of the upper leg, and locked when the upper leg is folded, and moved to the original position along the inner portion during the rotation of the upper leg from the inner portion during the rotation. It includes a rotation hook which is released and the lock is released.

In this case, by using the agitated bed, the pivoting hook formed between the rotational supports of the upper leg is inserted and rotated by locking the upper leg, and then rotating the upper leg downward. In addition, the extended posture of the upper leg is maintained by the surface contact between the pivotal support and the seat, and it can be seen that it can be folded and stored through the reverse process of the unfolded state during storage.

As a result, the upper and lower legs can be unfolded more quickly and easily by simply rotating the left and right sides without effort when using and storing on the gaskets. It can be seen that this contributes to the reduction of production cost.

And, there may be a plurality of embodiments of the present invention, the following will be described in detail with respect to the most preferred embodiment.

Through this preferred embodiment it is possible to better understand the objects, features and advantages of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the folding upper leg according to the present invention.

1 is an exploded perspective view showing the folded upper leg according to the present invention, Figure 2 is an explanatory view for coupling the upper leg to the seat of Figure 1, a perspective view showing the inner peripheral surface of the seat, Figure 3 This is a longitudinal cross-sectional view of the upper leg coupled to the left side of.

As shown in Figures 1 to 3, the folding upper leg according to the present embodiment is largely fixed to each corner of the bottom surface of the upper plate 70 and has a rotating space portion 50a formed to penetrate through one side to open in the vertical direction. The hemispherical base 50 and the upper leg 60 are coupled to the base 50 without rotation and are folded and unfolded with respect to the base 50.

In the above, the seat 50 is for holding the upper leg 60 so that it can be folded, and the screw 72 is formed through a plurality of screw holes 58 formed on the bottom surface of the upper plate 70 having a predetermined shape. It is fixedly installed by a fixing means such as.

The first and second coupling guides 52 and 52a are cut in the vertical direction so as to face each other at the upper sides of the rotating space 50a of the seat 50, and the first and second coupling guides ( The first and second pivot support portions 54 and 54a communicating with the 52 and 52a are formed in the horizontal direction by a predetermined length. In addition, the inner 56 is rounded and cut in the horizontal direction by a predetermined length on the lower end surface of the rotation space 50a between the first and second pivot support portions 54 and 54a.

1 and 2, a cylindrical pivotal support 62 is integrally formed at the upper end of the upper leg 60 so as to be fitted into the pivoting space 50a of the seat 50. Rotating pins 68, which are inserted into the first and second coupling guides 52 and 52a, rotate along the first and second pivotal support portions 54 and 54a through the upper end of the pivot support 62. It is.

In addition, the outer peripheral surface of the lower end portion of the pivot support 62 is inserted and moved to the inner portion 56 of the seat 50 when the upper leg is unfolded, and locked, and when the upper leg is folded, the inner leg 56 is moved to the original position during the rotation. As a result, the rotation hook 66, which is released from the inner portion 56 during the rotation and is released, protrudes vertically downward with respect to the rotation support interval 62. As shown in FIG.

The folded upper leg according to the present invention made as described above will be described in more detail with reference to FIGS. 1 to 5.

1 and 2, in order to assemble them in the state where the base 50 and the upper leg 60 are disassembled, first, the pivot support section 62 of the upper leg 60 is inserted into the rotation space 50a of the base 50. Press it down. In this case, both ends of the rotation pin 68 coupled to the rotation support member 62 coincide with the first and second coupling guides 52 and 52a of the seat 50. In this state, while holding the upper leg 60 and pulling it downward, both ends of the pivot pin 68 move vertically downward along the first and second coupling guides 52 and 52a, and Rotating hooks 66 are supported by the first and second pivotal support portions 54 and 54a which are in communication with each other so as to be horizontally rotatable without being separated downward, and protrude from the pivotal support section 62. The inner space 56 is formed on the rotational space portion 50a of the pedestal 50, which will be described in detail later, and is detachably coupled horizontally. When the base 50 and the upper leg 60 are assembled by the above method, the base 50 is positioned at an appropriate place on the bottom of the upper plate 70 on the gasket, and then the screw hole 58 of the base 50 is screwed ( Inserting and fixing the fixing means as shown in 72) is finally completed as shown in FIG. At this time, the rotation support interval 62 of the upper leg 60 is not separated from the seat 50 because the upper plate 70 blocks the first and second coupling guides 52 and 52a, and only the pivot pin 68. ) And the rotation hook 66 perform left and right rotations, that is, only horizontal rotation operations in the rotation space portion 50a.

In this way, the expansion and folding operation of the upper leg 60 in the completed state will be described in more detail with reference to FIGS. 3 to 5 below.

FIG. 4 is a plan view taken along the line A-A of FIG. 3 and shows the initial state in which the upper leg 60 is unlocked from the pedestal 50. That is, the upper leg 60 is an initial state for folding in the same direction as the dotted line of Figure 3 in a state perpendicular to the base 50. In such a state, in order to extend the upper leg 60 to use a gyoza image, first, hold the upper leg 60 and turn it to the left side with reference to FIG. 4, and the pivotal support 62 of the upper leg 60 is left. As shown in FIG. 5, both ends of the rotation pin 68 which rotates to the left direction in the rotation space part 50a of the 50, and penetrates the rotation support interval 62 are shown in FIG. , Along with the second pivot support portion 54 (54a), and the pivot hook 66 formed on the pivot support interval 62, are also shown in FIG. 5 along the inner portion 56 of the seat 50. Likewise, it rotates to the left direction. As described above, the pivot pin 68 and the pivot hook 66 are rotated to the left along the first and second pivot support portions 54 and 54a of the pedestal 50 and the inner portion 56, respectively. Even if the upper leg 60 is to be folded in the state as shown by the dotted line in FIG. 3, the pivot support 62 is in close contact with the inner surface of the seat 50, and the pivot hook 66 is the seat 50. Since the inner 66 is locked as shown in FIG. 5, the upper leg 60 does not fold at all toward the opened side of the seat 50 and the upper leg 60 is closed with respect to the seat 50. The unfolded and stably maintained in an unfolded state as shown in FIGS. 3 and 5.

And, in order to fold the upper leg 60 in order to store the gyosang image, when holding the upper leg 60, which is locked as shown in FIG. As shown in FIG. 4, the both ends of the pin 68 are rotated to the right along the first and second pivot support portions 54 and 54a of the seat 50, and are returned to their initial positions. The rotation hook 66 formed in the liver 62 also rotates to the right along the inner portion 56 during the rotation of the seat 50, and as shown in FIG. 4, the lock hook is released to its initial position. When the upper leg 60 held in the unlocked state is rotated upward with reference to FIG. 3, the pivot hook 66 formed on the pivot support 62 is rotated inside the seat 50. ) And the pivot support 62 is rotated upward with respect to the pivot pin 68 to escape from the pivot space 50a of the opened seat 50, as shown by the dotted line in FIG. 70) will be folded.

On the other hand, when the upper leg (60) is folded as shown in the dashed line of Figure 3, if you want to extend the upper leg (6) again, while holding the folded upper leg 60 and rotated downward with respect to the base 50 to turn to the vertical state As shown in FIG. 4, the rotation hook 66 of the support rod 62 is inserted into the inner portion 56 of the pedestal 50. As described above, by turning the upper leg 60 to the left in such a state, the upper leg 60 is locked to the pedestal 50 by the pivot hook 66 and the pivot pin 68, and is also pivotally supported. By the surface contact of the liver 62 and the rotation hook 66, it is to maintain a stable state without folding and shaking.

Meanwhile, as an example of comparison, in the conventional technique, ie, the upper leg folding structure of Korean Utility Model Registration No. 33186969, holding the support by one hand and holding the upper leg by the other hand to push upward or force it downward Unlike the difficulty of pulling out forcefully and the complexity of the structure of the upper leg and the support, the productivity is lowered, the present invention supports the rotation of the upper leg by holding the upper leg and rotating it downwards around the left leg and then rotating the upper leg to the left. It can be seen that the rotation hook formed in the liver is inserted and rotated internally during the rotation of the seat so that the upper leg is kept upright, and when it is stored on the gallows, it can be folded and stored through the reverse process of the expanded state.

In this result, according to the present invention, the upper and lower limbs can be unfolded more quickly and easily by simply rotating the left and right without any effort during the use and storage of the gyoza. Of course, due to the simplification of the zoom, there is an advantage that contributes to the reduction of the production cost.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended utility model registration claims of the present invention.

According to the folding upper legs of the present invention, which is clear from the above description, the upper and lower legs can be unfolded more quickly by simply rotating the left and right sides without effort when using and storing on the gasket, and also without shaking in the unfolded state of the upper legs. The more stable the gyoza image, of course, the structure is very simple, which contributes to the improvement of productivity and the reduction of production cost.
