The present invention relates to a vacuum table for clothes, and more particularly, to a technology that imparts a vacuum suction function so that clothes can be fixed to a table top plate during manufacture and ironing of clothes, controls the foot plate for controlling vacuum suction so as to maintain the vacuum state without being pushed by an operator one by one, and thereby enhances the convenience of an operator' work and enables adjustment to suit the operator's body by adjusting the height of the table top plate.
Generally, a vacuum table (or vacuum board) having a vacuum suction function is used on the table when performing sewing work in the process of manufacturing clothes or ironing in a laundry room, etc., thereby allowing the clothes to easily fix to the table top plate and enhance the convenience of the operator.
The vacuum table is composed of a top plate on which clothes are placed, a vacuum suction device is fixedly mounted at the lower part of the top plate, and the vacuum is controlled in the form of opening or closing the damper of the vacuum suction device through control of a foot plate mounted at the lower part of the table.
Due to such an operating method, vacuum suction is performed only in the state of stepping on the foot plate. Thus, the operator frequently step on and release the foot plate repeatedly. In addition, in order to maintain the vacuum suction state for a long time, since the foot plate must be pressed continuously, an operator's fatigue cannot but be weighted.
In the actual work site, it is difficult to press the foot plate continuously, and thus it is used in a cumbersome form, such as placing heavy objects such as bricks on the upper part of the foot plate or pulling the foot plate with a string in the direction of pressing to be fixed.
In addition, there is a problem that the height of the vacuum table cannot be adjusted structurally because the foot plate is connected to the damper of the vacuum suction device due to the characteristics of the vacuum table. Considering that the heights of the operators are diverse, it is necessary to adjust the height of the vacuum table
As related prior arts, Korean Utility Model Registration No. 20-0182435, entitled “Vacuum Suction Type Ironing Board”, and Korean Utility Model Registration No. 20-0127505, entitled “Wind Direction Changing Device for Ironing Board for Manufacturing Clothes”, disclose that a vacuum suction device is mounted on the above-mentioned table, and the clothes are fixed to the table when ironing or manufacturing clothes, thereby enhancing the convenience of operators.
However, as mentioned above, all of the above prior arts have a problem that since the foot plate that operates the vacuum suction device is only operated when it is pushed, the operator's legs and feet become more fatigued. All of the prior arts have in common the problem that the height of the table cannot be adjusted structurally.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, in the following description, a detailed explanation of known related function or technologies may be omitted to avoid unnecessarily obscuring the subject matter of the present invention.
A vacuum table for clothes according to the present invention comprises: a plurality of support bases 100 which is mounted vertically, an upper plate part 200 which is mounted on the upper part of the support base 100 so that clothes are placed on it, and has a vacuum suction hole 210 formed at the lower part thereof, a vacuum suction device 300 which is mounted at a lower part of the upper plate part 200 and generates suction pressure in the upper plate part 200 by a motor 310, a foot plate 400 which is mounted on a mounting rod 110 in the form of horizontally connecting the support base 100 and opens and closes a damper 320 of the vacuum suction device 300 to control the suction propriety of the upper plate part 200, a position fixing means 500 which is mounted on one side of the foot plate 400 to fix the position of the foot plate 400 in the form of supporting the upper part of the foot plate 400, and height adjusting means 600 which are respectively mounted on both sides of the support base 100 to adjust the height of the upper plate 200 by the operation of a cylinder 610, as shown in
The support base 100 of the present invention plays a supporting role so that the upper plate 200 can be spaced apart from the ground, and can be mounted at a total of 4 locations or 2 locations. Preferably, it is mounted at two locations so that the cylinder 610 of the height adjusting means 600 can easily ascent or descend both sides at the same time.
The upper plate part 200 is configured to place clothes on it, wherein a space is formed inside so that the vacuum pressure of the vacuum suction device 300 is generated, and a vacuum suction hole 210 is formed at the lower part so that air suction of the vacuum suction device 300 mounted at the lower part is transmitted to the upper plate part 200.
The vacuum suction device 300 is mounted at a lower part of the upper plate part 200 and generates vacuum pressure by the operation of the motor 310. At this time, a damper 320 is mounted in the vacuum suction device 300, and the damper 320 is connected with the rod-shaped operating rod 321 toward the lower part.
The foot plate 400 is configured to move the operating rod 321 to open and close the damper 320 of the vacuum suction device 300, wherein by opening and closing operation of the damper 320, the upper plate part 200 can be brought into a vacuum state, or the vacuum state can be released. That is, when the foot plate 400 is stepped on, the operating rod 321 is pulled and the damper 320 is opened, so that the suction of the motor 310 is transmitted to the vacuum suction hole 210 of the upper plate part 200. Further, when the foot is released from the foot plate 400 again, the operating rod 321 is restored to its original state and the damper 320 is closed.
The foot plate 400 is mounted on the mounting rod 110 in the form of horizontally connecting the support base 100, which can greatly improve the convenience of work by the position fixing means 500 mounted on one side of the foot plate 400.
The position fixing means 500 of the present invention is configured to be mounted on one side mounting rod 110 of the foot plate 400 as shown in
The position fixing means 500 specifically comprises: a clamp 511 fixed to the mounting rod 110 and a body part 510 in which a support plate 512 is formed to extend to the upper part of the clamp 511, operating shafts 520 which are horizontally mounted to protrude on both sides of the support plate 512 and mounted to be movable in the horizontal direction, a support block 530 which is mounted at one side end of the operating shaft 520 and supported in a form being placed on the upper part of the foot plate 400, a spring 540 which is mounted between the support block 530 and the support plate 512 to push the support block 530 toward the foot plate 400, a stopper 550 which is integrally formed on the operating shaft 520 and supported by the support plate 512 on the opposite side of the spring 540 to support the restoring force of the spring 540, and an operating plate 560 which is formed on the operating shaft 520 on the opposite side of the support block 530 to control the movement of the operating shaft 520, as shown in
The body part 510 is integrally formed with a clamp 511 and a support plate 512. As shown in the drawing, the clamp 511 is formed to be divided into an upper clamp 511a and a lower clamp 511b in the form of wrapping the mounting rod 110 in half. Further, one side are connected by a hinge to facilitate separation and coupling to the mounting rod 110, and the other side is structured so that it is fixed through screw coupling. That is, since the clamp 511 can be horizontally moved and rotated on the mounting rod 110 in a state where the screw is not coupled, the mounting position and mounting angle can be freely adjusted. Therefore, the mounting position of the operating shaft 520 can be changed according to the mounting angle of the clamp 511, thereby being able to apply in compliance with the structure of the foot plate 400.
The support plate 512 is formed on the upper clamp 511a, and has a hole formed there through so that the operating shaft 520 can be provided. A guide bushing 570 is integrally formed on one side of the support plate 512 to guide and support the operating shaft 520. The guide bushing 570 is formed to have a sufficient length so that the operating shaft 520 is stably supported and can move smoothly.
The operating shafts 520 are coupled to the support plate 512 in a penetrating manner, protrude from both sides of the support plate 512 and are mounted to be movable in a horizontal direction. In addition, a support block 530 and an operating plate 560 are formed at both ends of the operating shaft 520, respectively.
The support block 530 is formed in the direction of the foot plat 400 of the operating shaft 520, and is supported in a manner to place on the foot plate 400 during operation, so that the foot plate 400 remains pressed. And, the operating plate 560 moves the operating shaft 520 so that the support block 530 is moved away from the upper part of the foot plate 400 when the foot plate 400 is not desired to be fixed according to circumstances.
Further, the spring 540 is mounted between the support block 530 and the support plate 512 and serves to push the support block 530 toward the foot plate 400. The support block 530 is stably supported on the upper part of the foot plate 400 by the force of the spring 540. As the spring 540 is coupled, a stopper 550 supporting the restoring force of the spring 540 is formed on the operating shaft 520. The stopper 550 is formed on the opposite side of the spring 540 and is supported by the support plate 512, and has a shape of being in contact with the guide bushing 570 formed on the support plate 512.
In addition, it is preferable that the support block 530 is rotatably mounted at the end part of the operating shaft 520. When the support block 530 is coupled in a rotatable form in this way, the angle of the support block 530 is also rotated to match the inclined surface of the foot plate 400, so that the entire bottom surface of the support block 530 is in contact with the foot plate 400 and thus, it can be stably supported.
The operation process of the position fixing means 500 according to the present invention will be described with reference to the drawings. First,
Then, in order to fix the foot plate 400, the operating plate 560 is moved to the outside while pressing the foot plate 400 as shown in
Finally, when the operating plate 560 is placed as shown in
As described above, since the position fixing means 500 of the present invention controls the operation through the operator's feet, so that it is excellent in operational convenience. Because the mounting position can be freely adjusted through the clamp 511, it has the advantage of being applicable to the vacuum tables for clothes having various structures.
In addition, the support base 100 of the present invention comprises a lower frame 130 that supports the floor and an upper frame 120 connected to the upper plate part 200 in a form of being inserted into the lower frame 130 as shown in
In addition, the height adjusting means 600 mounted on the support base 100 is configured such that a cylinder 610 body is fixedly mounted on the first mount base 140 formed to protrude from the lower frame 130, and a piston rod of the cylinder 610 is connected to the protruding second mounting base 150 of the upper frame 120, so that the upper frame 120 is ascended by the operation of the cylinder 610 to adjust the height of the upper plate part 200.
Further, a third mounting base 160 is further formed on the lower frame 130, and the vacuum suction device 300 is installed in the form of being placed on the third mounting base 160, so that the position of the vacuum suction device 300 is fixed even when the height of the upper plate 200 is adjusted. Due to such a structure, the operation of the vacuum suction device 300, which could not be realized in the prior art, is performed smoothly, and the height of the upper plate part 200 can be adjusted.
A fixing pin 170 passing through the upper frame 120 and the lower frame 130 may be further coupled. The fixing pins 170 form pin holes (not shown) at predetermined heights in the upper frame 120 and the lower frame 130 so that they are inserted at appropriate heights according to the height adjustment of the upper plate part 200. In this way, as the fixing pin 170 is more defective, the load on the cylinder 610 can be minimized.
Further, the vacuum suction device 300 is preferably controlled so that the vacuum suction pressure becomes stronger as the height of the upper plate part 200 is higher. As the distance between the vacuum suction device 300 and the upper plate part 200 increases, the suction power may decrease. Thus, it is preferable to adjust the suction strength to suit the distance with the upper plate part 200. The detection of the height of the upper plate part 200 can be connected to the operation timer of the cylinder 610, and a separate sensor capable of detecting the distance to the upper plate part 200 may be provided.
The present invention has been described above with reference to the above embodiments, but it goes without saying that various modifications can be made within the scope of the technical idea of the present invention.
