Description

Technical Field

[0001] This utility model relates to the technical field of lifting human body sitting and lying devices, specifically a lifting human body sitting and lying device with a safety device. Background Technology

[0002] Human-shaped seating and reclining furniture (such as hanging chairs and swings) has always been popular as a tool for rest or entertainment. To increase space utilization, some electrically operated lifting human-shaped seating and reclining furniture are now available. They lower to a suitable height when needed and rise when not in use to avoid taking up space. However, because these electrically operated lifting and reclining furniture are electrically driven, accidental raising while the user is in use can easily cause a safety accident, thus posing a certain safety hazard. Utility Model Content

[0003] In order to overcome the defects in the existing technology, the objective of this utility model is to provide a lifting human body sitting and lying device with a safety device.

[0004] This utility model achieves its objective through the following technical solutions:

[0005] A lifting-type human sitting / reclining device with a safety device includes a human sitting / reclining device body, an electric lifting device, and a safety device. The human sitting / reclining device body is for sitting or lying down and is suspended from a building by a suspension mechanism and a first suspension rope. The electric lifting device can drive the human sitting / reclining device body to rise and fall. The safety device is adapted to the electric lifting device and can disconnect the transmission connection between the human sitting / reclining device and the electric lifting device by mechanical or electrical means; or, disconnect the power supply to the electric lifting device; or, lock and brake the electric lifting device to ensure that the electric lifting device cannot drive the human sitting / reclining device body to rise during use.

[0006] As a preferred technical solution, the suspension mechanism includes a transmission part, and a clutch mechanism is provided between the transmission part and the electric lifting device or between the electric lifting device and the power source; or, a second suspension rope is provided, with the upper end of the second suspension rope connected to the electric lifting device and the lower end connected to the body of the human sitting and lying device. The electric lifting device drives the second suspension rope, thereby driving the body of the human sitting and lying device to rise and fall. When it is lowered to the height of use, the first suspension rope bears the force. The second suspension rope is detachable from the body of the human sitting and lying device.

[0007] As a preferred technical solution, the lower end of the second suspension rope is provided with a detachable connection structure that can magnetically attract or snap onto the body of the human sitting and lying device, so as to realize the detachable connection between the second suspension rope and the body of the human sitting and lying device.

[0008] As a preferred technical solution, the suspension mechanism further includes a mounting base, a bearing seat slidably connected to the mounting base, and a spring disposed between the bearing seat and the mounting base. The transmission part is a transmission shaft that is rotatably supported by the bearing seat. When a person sits on the human reclining device, the transmission shaft and bearing seat can be compressed to overcome the spring force and descend, thereby disengaging the clutch mechanism. When the person leaves, the spring force can drive the transmission shaft and bearing seat to move upward, thereby engaging the clutch mechanism. Alternatively, at least one of the suspension mechanism and the electric lifting device is provided with a lateral slide rail and can slide laterally relative to each other. In use, the clutch mechanism can be disengaged by driving one of them, and when lifting is required, the clutch mechanism can be engaged by driving one of them.

[0009] As a preferred technical solution, it also includes a physical quantity triggered detection switch or a human presence induction trigger switch. When a user is sitting on the human body sitting or reclining device, the physical quantity triggered detection switch or the human presence induction trigger switch can be triggered, thereby cutting off the power supply to the electric lifting device or controlling the electric locking component to lock and brake the electric lifting device through electronic control.

[0010] As a preferred technical solution, a locking mechanism is provided between the suspension mechanism and the electric lifting device. The electric lifting device includes a motor and a rotating shaft driven by the motor. The rotating shaft can wind up the first suspension rope to achieve the lifting function. The suspension mechanism includes a mounting base, a bearing seat that is slidably connected to the mounting base, and a spring disposed between the bearing seat and the mounting base. The rotating shaft is rotatably supported by the bearing seat. When a person sits on the human reclining device, the rotating shaft and bearing seat can be compressed to overcome the elastic force of the spring and descend, thereby engaging and locking the locking mechanism. When the person leaves, the elastic force of the spring can drive the rotating shaft and bearing seat to move upward, thereby disengaging and unlocking the locking mechanism.

[0011] Compared with the prior art, this application has the following main advantages:

[0012] This application provides a lifting-type human reclining chair with a safety device. In use, when a user is seated on the chair, the device compresses the drive shaft and bearing seat, overcoming the spring force to descend and disengage the clutch mechanism. This disconnects the chair from the electric lifting device, ensuring the electric lifting device cannot lift the chair and preventing it from bearing stress, thus extending its lifespan. When not in use, the spring force drives the drive shaft and bearing seat upward, engaging the clutch mechanism and restoring the connection between the chair and the electric lifting device. The chair can then be lifted by the electric lifting device. The upper stop point of the chair is located near the building ceiling, allowing for easy storage of the chair.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] Example 1:

[0021] like Figure 1 As shown, a lifting-type human sitting or lying device with a safety device includes a human sitting or lying device body 1, an electric lifting device 2, and a safety device. The human sitting or lying device body 1 is for sitting or lying down and can be a swing, hanging chair, hammock, etc. It is suspended from the building by a suspension mechanism and a first suspension rope 4. The electric lifting device 2 can drive the human sitting or lying device body 1 to rise and fall. The safety device is adapted to the electric lifting device 2 and can mechanically disconnect the transmission connection between the human sitting or lying device and the electric lifting device 2.

[0022] The method of mechanically disconnecting the transmission connection between the human-shaped reclining device and the electric lifting device 2 specifically includes: the suspension mechanism includes a transmission part 31, the electric lifting device 2 includes a motor 21 and a rotating shaft 22 driven by the motor 21, and a clutch mechanism 5 is provided between the rotating shaft 22 and the electric lifting device 2. The suspension mechanism also includes a mounting base 32, a bearing seat 33 slidably connected to the mounting base 32, and a spring 34 disposed between the bearing seat 33 and the mounting base 32. In use, the mounting base 32 can be fixedly installed on the load-bearing wall or load-bearing beam of the building in a relatively load-bearing manner so that it can support a person sitting on the human-shaped reclining device body 1. The transmission part 31 is a transmission shaft and is rotatably supported by the bearing seat 33. When a person sits on the human-shaped reclining device, it can compress the transmission shaft and the bearing seat 33 to overcome the elastic force of the spring 34 and descend, thereby disengaging the clutch mechanism 5. When the person leaves, the elastic force of the spring 34 can drive the transmission shaft and the bearing seat 33 to move upward, thereby engaging the clutch mechanism 5. In this embodiment, the clutch mechanism 5 can be a mechanical clutch mechanism 5 that can transmit torque in the prior art.

[0023] This embodiment provides a lifting-type human reclining chair with a safety device. In use, when a user is seated on the chair body 1, the device compresses the drive shaft and bearing seat 33, overcoming the spring force of the spring 34 to descend and disengage the clutch mechanism 5. This disconnects the transmission connection between the chair body and the electric lifting device 2, ensuring that the electric lifting device 2 cannot drive the chair body 1 upwards during use and preventing the electric lifting device 2 from bearing stress, thus extending its service life. When not in use, i.e., when no one is seated on the chair body 1, the spring force of the spring 34 drives the drive shaft and bearing seat 33 upwards, engaging the clutch mechanism 5. This restores the transmission connection between the chair body and the electric lifting device 2, allowing the electric lifting device 2 to drive the chair body 1 upwards. In this embodiment, the upper stop point of the chair body 1 is located near the building ceiling, allowing for easy storage of the chair body 1. In other embodiments, the clutch mechanism 5 can also be located between the electric lifting device 2 and the power supply, so that the power supply to the electric lifting device 2 can be cut off when in use, thereby ensuring that the electric lifting device 2 cannot drive the human body sitting and lying device body 1 to rise when in use; when not in use, the power supply to the electric lifting device 2 is restored, so that the human body sitting and lying device body 1 can be driven to rise by the electric lifting device 2 to realize the storage of the human body sitting and lying device body 1.

[0024] Example 2:

[0025] like Figure 2As shown, a lifting-type human sitting or lying device with a safety device includes a human sitting or lying device body 1, an electric lifting device 2, and a safety device. The human sitting or lying device body 1 is for sitting or lying down and can be a swing, hanging chair, hammock, etc. It is suspended from the building by a suspension mechanism and a first suspension rope 4. The electric lifting device 2 can drive the human sitting or lying device body 1 to rise and fall. The safety device is adapted to the electric lifting device 2 and can mechanically disconnect the transmission connection between the human sitting or lying device and the electric lifting device 2.

[0026] The method of mechanically severing the transmission connection between the human-shaped seating / reclining device and the electric lifting device 2 specifically includes: the suspension mechanism includes a transmission part 31, a clutch mechanism 5 between the transmission part 31 and the electric lifting device 2, and the suspension mechanism also includes a mounting base 32 and a bearing seat 33 fixedly mounted on the mounting base 32. The suspension mechanism is provided with a transverse slide rail 35, which can be fixedly installed on a load-bearing wall or beam of a building in a relatively load-bearing manner to support a person sitting on the human-shaped seating / reclining device body 1. The mounting base 32 and the transverse slide rail 35 are slidably connected. In use, the clutch mechanism 5 can be disengaged by driving the transmission part 31 to move laterally, and the clutch mechanism 5 can be engaged by driving the mounting base 32 to move laterally when lifting is required. In other embodiments, the electric lifting device 2 can also be slidably connected to the transverse slide rail 35 to achieve the engagement or disengagement of the clutch mechanism 5. In this embodiment, the clutch mechanism 5 can be a mechanical clutch mechanism 5 capable of transmitting torque in the prior art.

[0027] This embodiment provides a height-adjustable reclining human body support with a safety device. When ready for use, the clutch mechanism 5 can be disengaged by laterally moving the drive mounting base 32, thereby cutting off the transmission connection between the human body support and the electric lifting device 2. This ensures that the electric lifting device 2 cannot drive the human body support body 1 to rise during use, and also avoids stress on the electric lifting device 2, thus extending its service life. When not in use and height adjustment is required, the clutch mechanism 5 can be engaged by laterally moving the drive mounting base 32, restoring the transmission connection between the human body support and the electric lifting device 2, allowing the electric lifting device 2 to drive the human body support body 1 to rise.

[0028] Example 3:

[0029] like Figure 3As shown, a lifting-type human sitting / reclining device with a safety device includes a human sitting / reclining device body 1, an electric lifting device 2, and a safety device. The human sitting / reclining device body 1 is for sitting or lying down and can be a swing, hanging chair, hammock, etc. It is suspended from the building by a suspension mechanism and a first suspension rope 4. The electric lifting device 2 includes a motor 21 and a rotating shaft 22 driven by the motor 21. The suspension mechanism includes a mounting base 32 and a bearing seat 33 fixedly installed in the mounting base 32. In use, the mounting base 32 can be fixedly installed on the load-bearing wall or load-bearing beam of the building in a relatively load-bearing manner so that it can support a person sitting on the human sitting / reclining device body 1. The electric lifting device 2 can drive the human sitting / reclining device body 1 to rise and fall. The safety device is adapted to the electric lifting device 2 and can mechanically disconnect the transmission connection between the human sitting / reclining device and the electric lifting device 2.

[0030] The mechanical disconnection of the transmission connection between the human sitting / reclining device and the electric lifting device 2 specifically includes: a second suspension rope 6, the upper end of which is connected to a rotating shaft 22 and can be wound up through the rotating shaft 22, and the lower end of which is connected to the human sitting / reclining device body 1. The electric lifting device 2 drives the second suspension rope 6, thereby driving the human sitting / reclining device body 1 to rise and fall. When it is lowered to the height of use, the first suspension rope 4 is subjected to force. The second suspension rope 6 is detachable from the human sitting / reclining device body 1. The lower end of the second suspension rope 6 is provided with a detachable connection structure 7 that can magnetically attract or snap onto the human sitting / reclining device body 1, so as to realize the detachable connection between the second suspension rope 6 and the human sitting / reclining device body 1. In this example, the detachable connection structure 7 can adopt the magnetic attraction structure or snap-on structure in the prior art.

[0031] This embodiment provides a lifting-type human reclining posture aid with a safety device. In use, when a user is seated on the posture aid body 1, the body 1 is supported by a first suspension rope 4, while the second suspension rope 6, which is connected to the electric lifting device 2, is disconnected from the body 1. This ensures that the electric lifting device 2 cannot drive the body 1 upwards during use, and also avoids stress on the electric lifting device 2, thus extending its service life. When not in use, i.e., when no one is seated on the posture aid body 1, the second suspension rope 6 is connected to the body 1, allowing the electric lifting device 2 to drive the body 1 upwards.

[0032] Example 4:

[0033] like Figure 4As shown, a lifting human sitting or lying device with a safety device includes a human sitting or lying device body 1, an electric lifting device 2, and a safety device. The human sitting or lying device body 1 is for sitting or lying down and can be a swing, hanging chair, hammock, etc. It is suspended from the building by a suspension mechanism and a first suspension rope 4. The electric lifting device 2 can drive the human sitting or lying device body 1 to rise and fall. The safety device is adapted to the electric lifting device 2 and can lock and brake the electric lifting device 2 by mechanical means.

[0034] The mechanical locking and braking of the electric lifting device 2 specifically includes: a locking mechanism 8 is provided between the suspension mechanism and the electric lifting device 2; the electric lifting device 2 includes a motor 21 and a rotating shaft 22 driven by the motor 21; the rotating shaft 22 can wind up the first suspension rope 4 to achieve the lifting function; the suspension mechanism includes a mounting base 32, a bearing seat 33 slidably connected to the mounting base 32, and a spring 34 disposed between the bearing seat 33 and the mounting base 32; the rotating shaft 22 is rotatably supported by the bearing seat 33; in this embodiment, the mounting base 32 can be fixedly installed on the load-bearing wall or load-bearing beam of the building in a relatively load-bearing manner so that it can support a person sitting on the human body sitting and reclining device body 1; the locking mechanism 8 includes a locking pin respectively disposed on the mounting base 32, a locking hole disposed on the rotating shaft 22, or a brake disc disposed on the rotating shaft 22 and having a locking hole. When a person sits on the human reclining device, the pressure of the pivot 22 and bearing seat 33 overcomes the elastic force of the spring 34 and causes the locking mechanism 8 to engage and lock. When the person leaves, the elastic force of the spring 34 can drive the pivot 22 and bearing seat 33 to move upward, thereby disengaging and unlocking the locking mechanism 8.

[0035] This embodiment provides a lifting-type human reclining posture aid with a safety device. In use, when a user is seated on the posture aid body 1, the rotating shaft 22 and bearing seat 33 are compressed to overcome the spring force of the spring 34, causing the locking mechanism 8 to engage and lock. This locks and brakes the electric lifting device 2, ensuring that the electric lifting device 2 cannot drive the posture aid body 1 upwards during use, and also preventing the electric lifting device 2 from bearing stress, thus extending its service life. When not in use, i.e., when no one is seated on the posture aid body 1, the spring force of the spring 34 drives the rotating shaft 22 and bearing seat 33 upwards, disengaging the locking mechanism 8. This releases the locking brake on the electric lifting device 2, allowing the electric lifting device 2 to drive the posture aid body 1 upwards.

[0036] Example 5:

[0037] A lifting-type human sitting or lying device with a safety device includes a human sitting or lying device body 1, an electric lifting device 2, and a safety device. The human sitting or lying device body 1 is for sitting or lying down and can be a swing, hanging chair, hammock, etc. It is suspended from the building by a suspension mechanism and a first suspension rope 4. The electric lifting device 2 can drive the human sitting or lying device body 1 to rise and fall. The safety device is adapted to the electric lifting device 2 and can cut off the power supply to the electric lifting device 2 through an electric control method; or, lock and brake the electric lifting device 2.

[0038] The electrical control method specifically includes: the installation of a physical quantity-triggered detection switch or a human presence-sensing trigger switch (such as pressure sensors, photoelectric sensors, infrared sensors, ultrasonic sensors, proximity switches, etc. in the prior art). When a user is seated on the human-shaped reclining device 1, the physical quantity-triggered detection switch or the human presence-sensing trigger switch can be triggered, thereby cutting off the power supply to the electric lifting device 2 or controlling the electric locking component (such as an electromagnet) to lock and brake the electric lifting device 2 through electrical control. The accompanying drawings for this embodiment are omitted, and the specific control circuit structure and working principle of this embodiment are electrical control technologies known in the technical field. They will not be described in detail in this example and do not affect the implementation by those skilled in the art.

[0039] It should be further explained that the above implementation is only described with two suspension ropes. When the lifting human body sitting and reclining equipment is a hanging chair or hammock, multiple suspension ropes are required to maintain balance. When implementing a multiple suspension rope scheme, multiple suspension ropes are adapted to multiple suspension mechanisms, transmission parts, and lifting devices; or multiple suspension ropes can be combined and adapted to the same suspension mechanism, transmission part, or lifting device.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
