Abstract
Description
Technical Field
[0001] This utility model relates to the field of massage chair technology, specifically to a commercial chair with anti-occupancy function. Background Technology
[0002] In society, various work and life pressures can easily lead to physical discomfort. People rarely have enough time outside of work to go to gyms or massage parlors. Massage chairs, as a tool for relieving fatigue, are very popular. However, due to their high price, the proportion of households owning massage chairs is relatively low. To meet the public's demand for massage chairs, some public places such as shopping malls, hotels, leisure squares, and parks have placed massage chairs for people to use for a fee. However, these public massage chairs are often occupied by people who don't need massages, preventing those who do need them from using them and thus reducing their utilization rate.
[0003] After a massage, people often leave items such as cell phones and bags on the massage chair. Existing anti-occupancy structures retract the anti-occupancy brackets directly via an electric cylinder after they are extended, and the retraction force is relatively large, which can easily damage the aforementioned cell phones, bags, and other items. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a commercial chair with anti-seat-occupancy function and protection of foreign objects after the anti-seat-occupancy function ends, in order to address the shortcomings of the prior art.
[0005] To achieve the above objectives, the following technical solution is adopted, including a base frame and a seat frame movably connected to the base frame. A first electric cylinder is connected between the seat frame and the base frame to drive the seat frame to move on the base frame. One end of the seat frame is connected to a small leg frame. A rotating shaft is provided at the end where the base frame and the small leg frame are connected. An anti-occupancy frame is hinged on the rotating shaft. A second electric cylinder is connected between the anti-occupancy frame and the base frame to drive the anti-occupancy frame to rotate. The anti-occupancy frame includes a first anti-occupancy frame and a second anti-occupancy frame. The second electric cylinder can cause the first and second anti-occupancy frames to lift or fall synchronously. When there is a foreign object between the first and second anti-occupancy frames, the first and second anti-occupancy frames can rotate and separate along the rotating shaft, and the first anti-occupancy frame can be tilted up to protect the foreign object.
[0006] Using the above technical solution, the anti-occupancy frame rotates through a rotating sleeve on a rotating shaft. Its power source is a first electric cylinder. The first electric cylinder is fixed to the bottom of the base frame and the anti-occupancy frame respectively through pins. When the first electric cylinder retracts, the anti-occupancy function is not activated. When the first electric cylinder extends, the anti-occupancy frame is lifted up, and the anti-occupancy function is activated. When there are no foreign objects between the first and second anti-occupancy frames, the first electric cylinder can make the first and second anti-occupancy frames rise or fall synchronously.
[0007] A commercial chair with anti-occupancy function can be further configured such that: the first anti-occupancy frame and the second anti-occupancy frame are detached; the first electric cylinder drives the second anti-occupancy frame to lift or lower; and the first anti-occupancy frame moves closer to and adheres to the second anti-occupancy frame when the first electric cylinder is pressed down, either by a pivot or by its own weight.
[0008] Using the above technical solution, the first electric cylinder can make the first anti-spot frame and the second anti-spot frame rise or fall synchronously. When there is a foreign object between the first anti-spot frame and the second anti-spot frame, the first anti-spot frame will be lifted by the foreign object, and the second anti-spot frame will fall with the electric cylinder. At this time, the second anti-spot frame and the second anti-spot frame will rotate and separate along the pivot, so that the first anti-spot frame and the second anti-spot frame have a space, so that the foreign object will not be injured and the foreign object will be effectively protected. At the same time, the first anti-spot frame can also be lowered by its own weight or by manual means to directly press the first anti-spot frame and the second anti-spot frame together, so that the two can rise or fall synchronously.
[0009] A commercial chair with anti-occupancy function can be further configured such that: a reset torsion spring is sleeved on the rotating shaft, the reset torsion spring is connected between the first anti-occupancy frame and the seat frame, and the reset torsion spring causes the first anti-occupancy frame to always rotate toward the second anti-occupancy frame.
[0010] Using the above technical solution, when there are no foreign objects between the first and second anti-occupancy frames, the return torsion spring keeps the first and second anti-occupancy frames in contact, allowing them to rise or fall synchronously. When there are no foreign objects between the first and second anti-occupancy frames, the first anti-occupancy frame overcomes the force of the torsion spring through the foreign object, thus tilting up and rotating away from the second anti-occupancy frame. Since both the first and second anti-occupancy frames are covered with sponge and leather in daily use, and the torsion spring is slowly lifted, it is less likely to damage foreign objects.
[0011] A commercial chair with anti-occupancy function can be further configured such that: the first anti-occupancy frame includes an anti-occupancy plastic frame that comes into contact with the human body and a reinforcing steel frame embedded in the bottom of the anti-occupancy plastic frame, and one end of the reset torsion spring is connected to the reinforcing steel frame.
[0012] By adopting the above technical solution, the anti-occupancy plastic frame makes the first anti-occupancy frame lighter and less likely to damage foreign objects, while the reinforcing steel frame is used to increase the overall strength of the anti-occupancy plastic frame and also has a longer service life when used to connect the reset torsion spring.
[0013] A commercial chair with anti-occupancy function can be further configured such that: the anti-occupancy plastic frame and the reinforcing steel frame have an arc-shaped head at the end away from the pivot to fit the seat frame, and the anti-occupancy plastic frame has a detection device on the side away from the reinforcing steel frame to detect the human body.
[0014] By adopting the above technical solution, an arc-shaped head is provided at the end of the anti-occupancy plastic frame and the reinforcing steel frame away from the pivot, which can make the first anti-occupancy frame fit more closely with the seat frame when it is not anti-occupancy. At the same time, it can also increase the overall length of the first anti-occupancy frame, thereby increasing the contact area with the human body. When the massage chair is unpaid and the human body sits on the anti-occupancy plastic frame, the detection device can send a signal to make the first electric cylinder lift the anti-occupancy frame, thereby achieving the anti-occupancy effect.
[0015] A commercial chair with anti-occupancy function can be further configured such that: a second electric cylinder is connected between the seat frame and the base frame to drive the seat frame to move on the base frame, and the base frame is provided with a small leg support at one end of the pivot.
[0016] Using the above technical solution, the seat frame can lie down or stand up on the base frame, and its power source is a second electric cylinder. The leg frame can be connected to the rotating shaft by hinge or direct positioning, thereby making the massage more comfortable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Figures 1-5 The commercial chair shown includes a base frame 1 and a seat frame 2 movably connected to the base frame 1. A second electric cylinder 6 connects the seat frame 2 to the base frame 1 to drive the seat frame 2 to move on the base frame 1. The seat frame 2 can recline or stand up on the base frame 1, and its power source is the second electric cylinder 6. One end of the seat frame 2 is connected to a leg support 4, which can be hinged to the seat frame 2 or directly positioned. A pivot 11 is provided at the connection end between the base frame 1 and the leg support 4, and an anti-occupancy frame 5 is hinged to the pivot 11. A first [unclear] connection is established between the anti-occupancy frame 5 and the base frame 1. The electric cylinder 3 drives the anti-occupancy frame 5 to rotate. The anti-occupancy frame 5 rotates via a rotating sleeve on the rotating shaft 11. Its power source is the first electric cylinder 3, which is fixed to the bottom of the base 2 and the anti-occupancy frame 5 via pins. The anti-occupancy frame 5 includes a first anti-occupancy frame 51 and a second anti-occupancy frame 52, which are rotatably connected to the rotating shaft 11. The first electric cylinder 3 can cause the first anti-occupancy frame 51 and the second anti-occupancy frame 52 to rise or fall synchronously. When the first electric cylinder 3 retracts and presses down, the anti-occupancy function is not activated. When the first electric cylinder 3 extends and lifts, the anti-occupancy frame 5 is lifted, and the anti-occupancy function is activated. Figure 2 As shown, when there are no foreign objects between the first anti-occupancy frame 51 and the second anti-occupancy frame 52, the first electric cylinder 3 can cause the first anti-occupancy frame 51 and the second anti-occupancy frame 52 to rise or fall synchronously; as Figure 5As shown, when there is a foreign object between the first anti-spot frame 51 and the second anti-spot frame 52, the first anti-spot frame 51 and the second anti-spot frame 52 are disengaged. The first anti-spot frame 51 is lifted by the foreign object, and the second anti-spot frame 52 descends with the first electric cylinder 3. At this time, the first anti-spot frame 51 and the second anti-spot frame 52 rotate and separate along the rotating shaft 11, creating a space between them. This prevents the foreign object from being injured and effectively protects it. Therefore, when there is a foreign object between the first anti-spot frame 51 and the second anti-spot frame 52, the first anti-spot frame 51 and the second anti-spot frame 52 can rotate and separate along the rotating shaft 11, causing the first anti-spot frame 51 to be lifted to protect the foreign object. A return torsion spring 53 is sleeved on the rotating shaft 11. The return torsion spring 53 is connected between the first anti-spot frame 51 and the base frame 2. The return torsion spring 53 ensures that the first anti-spot frame 51 always faces the second anti-spot frame. When the frame 52 rotates, and the return torsion spring 53 is not used, the first anti-spotting frame 51 moves closer to and adheres to the second anti-spotting frame 52 when the first electric cylinder 3 is pressed down by the pivot 11 or its own weight. The first anti-spotting frame 51 includes an anti-spotting plastic frame 511 that comes into contact with the human body and a reinforcing steel frame 512 embedded in the bottom of the anti-spotting plastic frame 511. The anti-spotting plastic frame 511 and the reinforcing steel frame 512 have an arc-shaped head 513 at the end away from the pivot 11 to fit the seat frame 2. The anti-spotting plastic frame 511 has a detection device 7 on the side away from the reinforcing steel frame 512 to detect the human body. The anti-spotting plastic frame 511 makes the first anti-spotting frame 51 lighter and less likely to damage foreign objects. The reinforcing steel frame 512 is used to increase the overall strength of the anti-spotting plastic frame 511. The return torsion spring 53 is connected to the reinforcing steel frame 512. The reinforcing steel frame 512 is used to connect the return torsion spring 53 and also has a longer service life.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
