Table on the table

The present invention relates to a lifting table which can be placed on a table and includes a base and a table and is connected by a scissor table leg, and the scissor table legs can be supported and supported at the center of gravity of the table plate. Zhang He, the table can be more stable without shaking when subjected to weight compression.

For the workers in the office, the sitting pressure is mainly sustained by the ischium, and the wrong sitting posture for a long time will cause the disc to be improperly stressed. In the long run, the disc may be deformed and cause back pain, and sedentary, fearing It is easy to cause decreased muscle endurance and worsening metabolism, which can lead to problems such as obesity and cardiovascular disease.

As early as 2011, Shibuya had many well-known companies such as Google, Facebook, etc., and there was a wave of employees standing up for office work. Therefore, a good table to improve work efficiency must be able to adjust the height of the table at any time. Finding suitable sitting and standing postures, but due to the desk table itself of the old desk, it is impossible to lift, lift or adjust the difficulty, or the desk equipment is difficult to update, so the manufacturer has developed the table table equipment, that is, On the old desk, a table that can be lifted and lowered is placed, and the working tools are placed on the table, so that the user can change to sit in a sitting or standing position at any time according to the needs of the work situation.

At present, most of the table tables we know include a base, a table, and a scissor table leg connected between the base and the table. The scissor table legs usually include two cross bars that are pivotally fixed together. And pivoting the upper and lower ends of the two cross bars closer to the side of the user to the table The inner side of the base and the distal end of the two cross bars are slidably disposed in the guide groove provided on the inner side of the table and the base, such as Taiwan Announcement TWM516896, TWM526853, TWM541243, EP2462868, US20160338486, and mainland notice CN205947441U, CN202681004 The patents such as CN205963350, CN205728692, CN204317907, etc. are all such structures, but the power for providing table lift is based on the spring tension, the electric drive of the motor and the screw, or the top thrust of the gas bar.

Regardless of the driving method, the table can be easily lifted and lowered, but they have a common point in the scissor table, that is, one end of the scissor table is fixed and not moved, and the other end is sliding. When the table is lowered to the lowest position, the two cross bars of the scissor table legs are nearly overlapped, and the upper and lower ends of the upper and lower sides are supported at the farthest point before and after the table and the base.

However, when the table is gradually raised, the pivotal ends of the two crossbars of the scissor table legs are kept in the original position, but the sliding mobile end is gradually approaching the pivotal end, that is, the scissor table. The original support center point of the foot is located at the center of the table and gradually shifts to one side of the table rather than the center, causing the support of the table to lose its center of gravity, thus causing the table to be unstable and unstable. .

The reason is that in order to improve the rise of the table top of the aforementioned known table, the scissor table legs are erected and biased toward one side of the table, causing the imbalance of the center of gravity of the support to cause an easy to shake problem. That is, the upper and lower ends of the scissor legs of the two cross-bars of the two cross-bars are provided, which are all slidably disposed in the front and rear guide grooves provided on the base and the table, and at the same time, the two sides are correspondingly intersected in the same direction. The upper and lower ends of the rod are adjacent to each other, and the connecting rods are pivotally connected with the middle of the table and the base, so that the scissor legs can be kept in the middle of the table below and are always supported in the table. The center of gravity of the room provides a more stable support for the table, making it less prone to sloshing.

The technical solution adopted by the present invention to solve the technical problem is as follows: a scissor table leg is connected between a base and a table, and a guide groove is arranged on the front and rear sides of the base and the opposite side of the table; the scissor table legs A sliding member is disposed on each of the upper and lower ends of the two cross-bars of the two sets of intermediate cross-members, so that the sliding members slide the table and the guide grooves provided in front and rear of the base, and at the same time, the two cross-bars with the two sides facing together The upper and lower ends are adjacent to each other, and a connecting rod is pivoted between the corresponding base and the middle of the table.

In the above solution, a gas pressure rod fixed to the pushing end of the table top is fixed between the two intersecting rods on the two sides of the scissor table.

Therefore, one of the corresponding crossbars of the scissor table legs of the present invention is provided with a connecting rod connected to the middle of the base plate and the table plate, so that the scissor table legs for driving the table plate can be kept at all times. In the middle of the center of gravity below the table, the uniform support supports the table to make it more stable without shaking.

Please refer to Figure 1 to Figure 4. The table on the table is included. Correspondingly disposed, a base 1 and a table 2, and a scissor table leg 3 connected between the base 1 and the table 2, and the scissor table 3 further comprises two groups of distances, The two cross bars 31, 32 of the intermediate cross-shafts of the tensioning can be synchronized, and the upper and lower ends of the cross bars 31, 32 are pivotally provided with the freely rotatable sliders 33, and the two cross-bars with the upper ends of the two ends are repeated. A gas pressure rod fixing seat 35 is disposed between the upper ends of the 32, so that a gas pressure rod 4 having a pushing end 41 is fixed on the seat, and the pushing end 41 of the gas pressure rod 4 is locked on the back surface of the table board 2 A fixing seat 21 fixed at the side.

In addition, the inner side of the base 1 opposite to the table 2 is provided with guide grooves 10, 20 at the front and rear sides, so that the sliders 33 provided at the upper and lower ends of the cross bars 31, 32 of the scissor table legs 3 are arranged. Slide on the bases 1 corresponding to the upper and lower sides and the guide grooves 10, 20 on the table 2, and then make the cross bars 31 (or the cross bars 32) corresponding to the two sides of the scissor table legs 3 in the same direction. A pivotal link 34 is pivoted adjacent to the upper and lower ends, and the other ends of the upper and lower links 34 are respectively pivoted to the pivoting seat 11 provided at the middle of the adjacent base 1 and the table 2. 23, and then the scissor table legs 3 are installed in the middle of the table 2 below.

Secondly, the front side of the table 2 is provided with a carrier 22 for lowering the keyboard and the like, and a wrench 5 for turning on the back side of the table 2 is provided, and then a cable is connected to the fixed gas pressure bar 4. In the fixing seat 21 at the pushing end 41, the stretching of the urging wrench 5 is used to control the expansion and contraction of the pushing end 41 of the gas pressure bar 4, so that the table 2 can be saved and easily lifted and positioned.

Therefore, under the pulling of the connecting rods 34, when the user moves the table 2, the two intersecting rods 31, 32 of the scissor table legs 3 can not only keep the table 2 when the shearing is performed. Vertical lifting without the front and rear offset, and also keeping the position of the scissor table 3 at the center of the center of gravity below the table 2, so that the scissor table 3 is always supported in the middle of the table 2 The stability of the center of gravity of the table 2 is enhanced, so that the table 2 can withstand greater weight and is less prone to Shaking happens.

In addition, as shown in FIG. 5, when the table 2 is lowered to the lowest position, the carrier 22 thereon can also be lower than the height of the originally placed table, which is just suitable for the operation of the keyboard when the user is riding.
