Abstract

This invention discloses a multifunctional chair for the elderly, relating to the field of medical assistive device technology. It includes a seat, a massage section, and a cover. The invention features two symmetrical massage mechanisms at the lower leg position of the seat. A semi-circular plate conforms to the contour of the lower leg. The drive assembly employs a structure of a drive motor, an eccentric block, a sliding frame, and a push rod, driving a pushing inclined block to reciprocately push a pushing column. This causes the massage column to extend and retract along movable holes. Combined with the resetting action of a reset frame and a tension spring, this achieves reciprocating massage of the lower leg. Simultaneously, the distance between the pushing inclined block and the pushing column changes linearly with the height of the massage column, allowing different parts of the lower leg to receive sequential massage. This effectively simulates manual massage movements, promoting blood circulation in the lower legs of elderly people who sit for long periods, relieving numbness and soreness in the lower limbs, improving coldness in the lower legs caused by weakened blood circulation in the elderly, and reducing health problems such as lower limb edema and venous thrombosis.

Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a multifunctional chair for the elderly. Background Technology

[0002] The demand for mobility aids for the elderly is growing. Due to the decline in physical strength, the elderly cannot stand or walk for long periods of time and usually need to sit down to rest. As a movable seat for the elderly, wheelchairs can provide a place for them to rest and also provide mobility. At the same time, as the main means of transportation and a commonly used seat for the elderly in their daily travel and home life, the functional design of wheelchairs is gradually expanding from simple mobility support to comfort and care. While existing multi-functional wheelchairs on the market have integrated some massage or heating functions, such as adding seat cushions, to improve the comfort of the elderly, there are some problems with the design for the care of the lower limbs, especially the calves. Currently, to keep warm, a blanket is often placed under the legs of the elderly while they are sitting. However, the blanket hangs down at the calves and does not fit the calves. Moreover, the blanket at the calves will slip off due to gravity. At the same time, prolonged sitting can lead to poor blood circulation in the lower limbs, which can also cause the temperature of the calves to drop. The front of the calves is easily exposed to cold, and the blood circulation in the lower limbs of the elderly is inherently weak, making them prone to feeling cold in their calves, thus affecting the health of the lower limbs. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, this invention provides a multifunctional chair for the elderly. In addition to providing a movable chair for the elderly, a massage component is designed at the lower leg position to promote blood circulation in the lower leg. At the same time, a heated blanket is designed on the front side of the lower leg to protect the front of the lower leg and prevent heat loss.

[0004] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: A multifunctional chair for the elderly includes a seat, a massage section, and a cover. The seat has a massage section at the lower leg position. The massage section includes two sets of massage mechanisms, each of which includes a massage component and a drive component. The drive component drives the massage component to work. The massage section has a cover, which includes a fixing component and a heating component. The fixing component is located at both ends on both sides of the massage section, and the heating component is located inside the fixing component.

[0005] Preferably, the seating portion is configured as a seat.

[0006] Preferably, the seat is configured as a wheelchair.

[0007] Preferably, the massage component includes a semi-circular plate, which is disposed at the lower leg position of the seat. An outer frame is fixedly connected between the semi-circular plate and the seat. Several movable holes are opened on both sides of the semi-circular plate, and massage columns are slidably connected in the movable holes.

[0008] Preferably, a push column is fixedly connected to the end of the massage column away from the center of the semi-circular plate. The push column is perpendicular to the massage column. The drive assembly includes a push rod, which is located on the side of the push column away from the massage column. Several push blocks are fixedly connected to the push rod, and the push blocks cooperate with the push column.

[0009] Preferably, the distance between the pushing wedge and the pushing column varies linearly according to the height position of the pushing column in the semi-ring frame; that is, as the height decreases, the distance between the pushing wedge and the pushing column gradually increases.

[0010] Preferably, the drive assembly further includes a drive motor, with drive shafts on both sides of the drive motor. An eccentric block is fixedly connected to the drive shaft, and a sliding column is fixedly connected to the eccentric block at a position away from the drive shaft. A sliding frame is provided on the sliding column, and a sliding groove is opened in the middle of the sliding frame. The sliding column is slidably connected in the sliding groove, and a connecting rod is fixedly connected between the sliding frame and the push rod.

[0011] Preferably, a reset frame is fixedly connected to the side of the push column near the outer frame, and a tension spring is fixedly connected between the reset frame and the outer frame.

[0012] Preferably, the outer frame on the first side is provided with a covering strip, the first end of the covering strip is fixedly connected to the outer frame on the first side, the second end of the covering strip is engaged with the outer frame on the second side, the second end of the covering strip is fixedly connected with an adhesive surface, and the outer frame on the second side is fixedly connected with a fixing surface, the adhesive surface and the fixing surface are adhesively engaged.

[0013] Preferably, a heating wire is fixedly connected inside the covering strip, and a controller is fixedly connected to the outer frame position on the first side of the covering strip, and the controller is electrically connected to the heating wire. The heating element is controlled by a controller, which is electrically connected to the drive motor.

[0014] The beneficial effects of this invention are: This invention discloses a multifunctional chair for the elderly. Two symmetrical massage mechanisms are installed at the lower leg position of the seat area. A semi-circular plate conforms to the contour of the lower leg. The drive assembly consists of a drive motor, an eccentric block, a sliding frame, and a push rod. This drives a pushing inclined block to reciprocately push a pushing column, causing the massage column to extend and retract along movable holes. Combined with the resetting action of a reset frame and a tension spring, this achieves a reciprocating massage of the lower leg. Simultaneously, the distance between the pushing inclined block and the pushing column changes linearly with the height of the massage column, allowing different parts of the lower leg to receive sequential massage. This effectively simulates manual massage movements, promoting blood circulation in the lower legs of elderly people who sit for long periods, relieving numbness and soreness in the lower limbs, improving coldness in the lower legs caused by weakened blood circulation in the elderly, and reducing health problems such as lower limb edema and venous thrombosis.

[0015] This invention features covering sections on both sides of the massage area, with the adhesive surface of the covering strip and the fixing surface of the outer frame enabling detachable fixation. This allows the heated blanket to conform to the front of the calf according to individual body shape and needs, avoiding the problem of the front of the calf being exposed due to gravity-induced sagging or slippage, as is common with traditional blankets. Simultaneously, the covering strip integrates heating wires, and the temperature is regulated by a controller, continuously providing warmth and protection to the front of the calf and reducing heat loss. The heating and massage functions work synergistically; heating dilates blood vessels, enhancing the blood circulation-promoting effect of massage and further improving cold calves, making it especially suitable for autumn and winter or for elderly people with a cold constitution.

[0016] This invention provides a covering on both sides of the massage area, and uses the adhesive surface of the covering tape and the fixing surface of the outer frame to achieve detachable fixation, so that the heated blanket fits tightly against the front of the calf, avoiding the problem of the front of the calf being exposed due to gravity falling or slipping of traditional blankets.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] like Figures 1 to 12As shown, this embodiment of the present disclosure provides a multifunctional chair for the elderly (1), including a seat, a massage part and a cover part. The seat is provided with a massage part at the lower leg position. The massage part includes two sets of massage mechanisms. The massage mechanism includes a massage component and a drive component. The drive component drives the massage component to work. The massage part is provided with a cover part. The cover part includes a fixing component and a heating component. The fixing component is located at both ends on both sides of the massage part. The fixing component is provided with a heating component inside. The seating section is configured as a seat (1); The seat (1) is configured as a wheelchair; Compared with existing technologies, this setup is advantageous on the basis of like Figures 2 to 8 As shown, in some embodiments, the massage assembly includes a semi-ring plate (2), which is disposed at the lower leg position of the seat. An outer frame (201) is fixedly connected between the semi-ring plate (2) and the seat. Several movable holes (202) are opened on both sides of the semi-ring plate (2), and massage columns (210) are slidably connected in the movable holes (202). The massage column (210) is fixedly connected to a push column (211) at one end away from the center of the semi-circular plate (2). The push column (211) is perpendicular to the massage column (210). The drive assembly includes a push rod (220). The push rod (220) is located on the side of the push column (211) away from the massage column (210). Several push inclined blocks (221) are fixedly connected to the push rod (220). The push inclined blocks (221) cooperate with the push column (211). The distance between the pushing wedge (221) and the pushing column (211) varies linearly according to the height position of the pushing column (211) in the semi-ring frame; that is, as the height decreases, the distance between the pushing wedge (221) and the pushing column (211) gradually increases. The drive assembly also includes a drive motor (230), with drive shafts (231) on both sides of the drive motor (230). An eccentric block (232) is fixedly connected to the drive shaft (231). A sliding column (233) is fixedly connected to the eccentric block (232) at a position away from the drive shaft (231). A sliding frame (223) is provided on the sliding column (233). A sliding groove (224) is opened in the middle of the sliding frame (223). The sliding column (233) is slidably connected in the sliding groove (224). A connecting rod (222) is fixedly connected between the sliding frame (223) and the push rod (220). A reset frame (212) is fixedly connected to the push column (211) on the side near the outer frame (201), and a tension spring (213) is fixedly connected between the reset frame (212) and the outer frame (201). Compared with existing technologies, this setup is advantageous because the semi-circular plate can precisely conform to the contour of the calf, and multiple massage columns can be used to wrap and massage the calf. The height matching design of the push block and the push column allows for a differentiated massage sequence for different parts of the calf, improving massage comfort. The tension spring reset mechanism enables the massage columns to reciprocate stably, simulating the dynamic effect of manual pressure and promoting blood circulation in the calves of the elderly.

[0022] like Figures 9 to 12 As shown, in some embodiments, the outer frame (201) on the first side is provided with a covering strip (3), the first end of the covering strip (3) is fixedly connected to the outer frame (201) on the first side, the second end of the covering strip (3) is engaged with the outer frame (201) on the second side, the second end of the covering strip (3) is fixedly connected with an adhesive surface (301), and the outer frame (201) on the second side is fixedly connected with a fixing surface (302), the adhesive surface (301) and the fixing surface (302) are adhesively engaged; A heating wire (311) is fixedly connected inside the covering strip (3), and a controller (310) is fixedly connected to the covering strip (3) at the position of the first side outer frame (201). The controller (310) is electrically connected to the heating wire (311). The heating wire (311) is controlled by the controller (310). The controller (310) is electrically connected to the drive motor (230). The drive motor (230) is controlled by the controller (310).

[0023] Compared with existing technologies, this design allows the covering strip to fit snugly against the front of the calf through an adhesive fixing structure, solving the problems of traditional blankets slipping off easily and failing to provide continuous protection for the front of the calf; the heating function is integrated into the covering strip to keep the front of the calf warm and reduce heat loss; and it works in conjunction with the massage function to improve blood circulation in the lower limbs.

[0024] In summary, this invention provides a multifunctional chair for the elderly (1). The invention features two symmetrical massage mechanisms at the lower leg position of the seat area. A semi-circular plate (2) conforms to the contour of the lower leg. The drive assembly consists of a drive motor (230), an eccentric block (232), a sliding frame (223), and a push rod (220). This drives the pusher block (221) to reciprocately push the pusher column (211), causing the massage column (210) to extend and retract along the movable hole (202). Combined with the reset mechanism (212) and the tension spring (213), this achieves reciprocating massage of the lower leg. Simultaneously, the distance between the pusher block (221) and the pusher column (211) changes linearly with the height of the massage column (210), allowing different parts of the lower leg to receive sequential massage. This effectively simulates manual massage, promotes blood circulation in the lower legs of elderly people who sit for long periods, relieves numbness and soreness in the lower limbs, improves the problem of coldness in the lower legs caused by weakened blood circulation in the lower limbs due to old age, and reduces health problems such as lower limb edema and venous thrombosis.

[0025] This invention provides a covering section on both sides of the massage area, and utilizes the adhesive surface (301) of the covering strip (3) and the fixing surface (302) of the outer frame (201) to achieve detachable fixation. This allows the heated blanket to fit the front of the calf according to ergonomic differences and needs, avoiding the problem of the front of the calf being exposed due to gravity-induced drooping and slipping of traditional blankets. At the same time, the covering strip (3) integrates an electric heating wire (311), and the temperature is regulated by a controller (310), continuously providing warmth and protection to the front of the calf and reducing heat loss. The heating function and the massage function work together. Heating can dilate blood vessels, which helps to enhance the effect of massage on promoting blood circulation and further improve the problem of cold calves, especially suitable for the elderly in autumn and winter or those with a weak constitution.

[0026] The present invention provides a covering part on both sides of the massage part, and uses the adhesive surface (301) of the covering strip (3) and the fixing surface (302) of the outer frame (201) to achieve detachable fixing, so that the heated blanket fits tightly against the front of the lower leg, avoiding the problem of the front of the lower leg being exposed due to gravity falling and slipping of the traditional blanket.
