Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a composite linkage mechanism for foot massage devices that can simultaneously perform rotational massage on the toes and scraping massage on the arch and heel. Background Technology

[0002] With increasing health awareness, massage chairs and other massage equipment are becoming more and more popular. Massage chairs are usually equipped with foot massage devices to massage and relax the feet. The soles of the feet contain multiple reflex zones, and different parts such as the toes, arches, and heels require different massage techniques and pressures to achieve the best massage effect.

[0003] In existing technologies, foot massage devices typically only offer a single massage method. For example, some foot massage devices use rotating rollers to perform rolling massage on the soles of the feet, which can only provide simple squeezing massage and cannot achieve back-and-forth scraping massage, resulting in poor massage effects on the feet. To improve upon these shortcomings, Chinese Patent Publication No. CN213251158U discloses a foot pressing and kneading and calf stretching massage device. This device has a front massage block, a middle roller, and a rear massage block respectively arranged at the front, middle, and rear ends of the lower foot massage area. The middle roller is circumferentially linked on a first drive shaft. The front and rear massage blocks are connected to the first drive shaft via eccentric wheels. The first drive shaft, through the eccentric wheels, can drive the front and rear massage blocks to move back and forth to achieve scraping massage.

[0004] However, the aforementioned existing technology still has the following shortcomings: First, its front and rear massage blocks are two independent components, which perform scraping massage on the front and back of the sole of the foot respectively. The structure is not compact enough, and the middle roller can only provide rotational massage, and the massage coverage of the toe area and arch area is not comprehensive. Second, its scraping massage can only achieve simple forward and backward linear movement, and the massage method is monotonous. It cannot perform precise bionic scraping massage on the curvature of the arch and specific positions of the heel. Third, it does not fully consider the linkage and coordination between toe massage and arch and heel massage, and cannot achieve complete coverage massage of the entire sole of the foot through a single drive mechanism.

[0005] Therefore, there is an urgent need for a compact composite linkage mechanism that can simultaneously perform rotational massage on the toes and scraping massage on the arch and heel, with all massage methods linked together through the same drive mechanism. Utility Model Content

[0006] The purpose of this utility model is to provide a combined linkage mechanism for arch kneading and heel scraping, so as to solve the technical problems of existing foot massage devices having a single massage mode, incomplete massage coverage, and non-compact structure.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A combined mechanism for arch kneading and heel scraping includes a mounting frame and a drive mechanism. The drive mechanism is mounted on the mounting frame and includes a drive motor and a transmission shaft driven by the drive motor. The mechanism is characterized by further comprising: The massage wheel assembly is sleeved on the drive shaft and rotates synchronously with the drive shaft. The massage wheel assembly is provided with an eccentric drive part and massage protrusions on the outer peripheral surface of the massage wheel assembly, which can massage the human toes. The scraping assembly includes a scraping base, which has a connecting part and a massage part. The connecting part is connected to an eccentric drive part, and the massage part has massage protrusions. When the drive shaft rotates, the massage wheel assembly can massage the toes of the human body, while the eccentric drive unit drives the scraping seat to reciprocate linearly, so that the massage unit can perform scraping massage on the arch and heel of the human body.

[0008] By adopting the above technical solution, the massage roller assembly and the scraping assembly are integrated onto the same drive shaft. The massage roller assembly rotates synchronously with the drive shaft, using the massage protrusions on its outer circumference to perform a rotary kneading massage on the toes. Simultaneously, the eccentric drive unit integrated on the massage roller assembly converts the rotational motion of the drive shaft into the linear reciprocating motion of the scraping seat, allowing the massage protrusions on the massage unit to perform a back-and-forth scraping massage on the arch and heel. A single drive motor drives two different massage motions—rotary massage and linear scraping—through a single drive shaft, resulting in a highly compact structure and high transmission efficiency. The rotary massage of the massage roller assembly covers the toe area, while the linear scraping of the scraping seat covers the arch and heel area. The combined effect of these two massage methods fully covers the massage needs of the entire sole of the foot, achieving comprehensive massage of the front, middle, and back of the foot.

[0009] Preferably, the massage wheel assembly includes a main massage wheel sleeved on a drive shaft and a side wheel located on at least one side of the main massage wheel. The outer circumferential surface of the main massage wheel is provided with a plurality of massage protrusions of equal height, and the outer circumference of each side wheel is provided with massage protrusions. The massage protrusions on the main massage wheel and the side wheel work together to massage the human toes.

[0010] By adopting the above technical solution, the massage roller assembly consists of a main massage roller mounted on a drive shaft and a side roller located on at least one side of the main massage roller. The main massage roller and the side roller together form a multi-wheel coordinated massage layout for the toe area. Multiple massage protrusions of equal height are unevenly distributed on the outer circumference of the main massage roller. This uneven distribution design allows the massage protrusions to press against the toes at irregular intervals during rotation, simulating the rhythmic feel of hand kneading and avoiding the monotonous massage sensation caused by evenly distributed massage protrusions. The outer circumference of the side rollers is also equipped with massage protrusions. The massage protrusions on the main massage roller and the side rollers alternately press and knead the toes from different angles, increasing the massage contact area and providing a more comprehensive massage. The layout of the main massage roller in the middle and the side rollers on the sides is adapted to the arrangement of human toes.

[0011] Preferably, there are two side wheels located on both sides of the main massage wheel. Each side wheel has an eccentric wheel body on the side closest to the main massage wheel. The two eccentric wheel bodies constitute the eccentric drive unit. The connecting part of the scraping seat is sleeved on the outer periphery of the eccentric wheel body.

[0012] By adopting the above technical solution, two side wheels are symmetrically arranged on both sides of the main massage wheel, forming a symmetrical massage wheel assembly structure. The side wheels on both sides move synchronously when the drive shaft rotates, resulting in balanced force and smooth operation. Each side wheel has an eccentric wheel body on the side closest to the main massage wheel, and the two eccentric wheels together constitute the eccentric drive unit. Integrating the eccentric drive unit directly onto the side wheel allows it to perform two functions simultaneously: first, it participates in toe rotation massage through the massage protrusions on its outer circumference; second, it provides eccentric driving force to the scraping base through the eccentric wheels. This multifunctional design reduces the number of parts required for additional independent eccentric wheels, making the overall structure more compact. The connecting part of the scraping base is fitted onto the outer circumference of the eccentric wheel body, with a surface contact fit between the two, resulting in a large force transmission area and stable and reliable operation.

[0013] Preferably, the two side wheels are fixedly connected to the drive shaft, and the two sides of the main massage wheel are provided with eccentric connecting parts, which are fixedly connected to the eccentric wheel body of the corresponding side wheel; the outer circumferential surface of the eccentric wheel body is provided with multiple protrusions.

[0014] By adopting the above technical solution, the two side wheels are fixedly connected to the drive shaft, ensuring that the side wheels and the drive shaft rotate synchronously without relative slippage, resulting in precise transmission. Both sides of the main massage wheel are equipped with eccentric connecting parts, which are fixedly connected to the eccentric wheel bodies of the corresponding side wheels, forming a rigid connection between the main massage wheel and the eccentric wheel bodies of the side wheels. Thus, the main massage wheel, side wheels, and eccentric wheel bodies are integrated into one unit. The rotational motion of the drive shaft is simultaneously transmitted to both the main massage wheel and the eccentric wheel body. The main massage wheel is responsible for rotational massage, while the eccentric wheel body drives the scraping seat. Their movements are coordinated and synchronous, without phase deviation. Multiple raised ribs are provided on the outer circumference of the eccentric wheel body. These ribs increase the contact friction coefficient between the eccentric wheel body and the scraping seat body connection, preventing slippage when the eccentric wheel body drives the scraping seat body, and improving the reliability and transmission efficiency of the eccentric drive.

[0015] Preferably, guide grooves are provided on both the left and right sides of the scraping base, and a support shaft is provided on the mounting frame at the position corresponding to the guide groove. The support shaft passes through the guide groove to provide guidance for the linear reciprocating motion of the scraping base.

[0016] By adopting the above technical solution, guide grooves are provided on both the left and right sides of the scraping device body, and a support shaft is provided on the mounting frame corresponding to the position of the guide groove, passing through the guide groove. The cooperation between the guide groove and the support shaft provides precise guidance and limitation for the linear reciprocating motion of the scraping device body: the length of the guide groove limits the maximum stroke of the scraping device body, and the sliding cooperation of the support shaft in the guide groove ensures that the scraping device body can only move in a straight line along the extension direction of the guide groove, without deflection or wobbling. The structure of the guide groove and the support shaft is simple, requiring no additional guide rails or slider assemblies, resulting in low manufacturing costs and convenient assembly. The support shaft also serves to support part of the weight of the scraping device body, reducing the load on the eccentric wheel.

[0017] Preferably, the massage area on the gua sha base includes an arch massage area and a heel massage area. The heel massage area is set lower than the arch massage area. The heel massage area corresponds to the position of the human heel, and the arch massage area corresponds to the position of the human arch.

[0018] By adopting the above technical solution, the massage area on the scraping device is designed with an arch massage area and a heel massage area. The heel massage area is positioned lower than the arch massage area, creating a height difference that matches the physiological curve of the human foot. The human foot arch is an upward-curving arc, and the heel is a protruding circular area, with the arch higher than the heel. The higher arch massage area provides close-fitting scraping to the arched area of ​​the foot; the lower heel massage area provides scraping to the protruding area of ​​the heel. This height difference design allows the arch massage area and heel massage area to apply appropriate pressure to the arch and heel respectively during the back-and-forth movement of the scraping device. The massage intensity matches the physiological structure of each part, resulting in high massage comfort and a good biomimetic effect.

[0019] Preferably, a scraping cover is detachably provided above the massage part, and the massage protrusion is provided on the scraping cover.

[0020] By adopting the above technical solution, the scraping cover and massage part are separately designed. Users can replace the scraping cover with different hardness, different raised shapes, or different raised densities according to their own massage needs, achieving a personalized massage experience. For example, when strong stimulation is needed, a harder scraping cover with higher raised areas can be used, while a softer scraping cover with lower raised areas can be used when gentle massage is needed. When the massage raised areas on the scraping cover wear down due to long-term use, only the scraping cover needs to be replaced, without replacing the entire scraping base, resulting in low maintenance costs and flexible and convenient use.

[0021] Preferably, rotating seats are fixedly provided on both sides of the mounting frame, and the two ends of the drive shaft are rotatably installed in the rotating seats; connecting blocks are provided on the left and right sides of the mounting frame corresponding to the scraping seat, and the two ends of the support shaft are connected between the two connecting blocks.

[0022] By adopting the above technical solution, rotating seats are fixedly installed on both sides of the mounting frame. The two ends of the drive shaft are rotatably mounted in the rotating seats, which provide stable support for both ends of the drive shaft, ensuring its rotational accuracy and stability at high speeds and reducing vibration and noise. Connecting blocks are provided on the left and right sides of the mounting frame corresponding to the scraping base. The two ends of the support shaft are connected between two connecting blocks, which provide fixed support for both ends of the support shaft. Both the rotating seats of the drive shaft and the connecting blocks of the support shaft are fixed to the mounting frame, unifying the installation reference and ensuring the relative positional accuracy between the drive shaft and the support shaft, thereby ensuring precise fit between the massage roller assembly and the scraping assembly.

[0023] Preferably, the drive mechanism further includes a turbine housing, a drive shaft passing through the turbine housing, and a bearing between the drive shaft and the turbine housing; a turbine is provided inside the turbine housing, the turbine is fixedly sleeved on the drive shaft, and a worm is provided on the output shaft of the drive motor, the worm being connected to the turbine drive.

[0024] By adopting the above technical solution, the drive mechanism is equipped with a turbine housing, through which the drive shaft passes. A bearing is installed between the drive shaft and the turbine housing, providing rotational support for the drive shaft, reducing rotational friction, and improving transmission efficiency. A turbine is housed within the turbine housing and is fixedly mounted on the drive shaft. A worm gear is mounted on the output shaft of the drive motor, and the worm gear is connected to the turbine drive. The worm gear turbine drive features smooth transmission and low noise, suitable for the low-noise operating environment requirements of massage equipment. The worm gear turbine drive also has a self-locking characteristic, preventing the massage wheel assembly from rotating in the opposite direction under the pressure of the user's feet when the drive motor stops. The turbine housing encapsulates the transmission components, providing dust and foreign object protection and maintaining lubrication, thus extending the service life of the transmission components.

[0025] Preferably, it also includes a groove frame, which is fixed above the mounting frame. The groove frame has two placement grooves for placing human feet, with a dividing section between the two placement grooves. The bottom of the placement grooves has an opening, and the massage roller assembly and the scraping assembly are set with corresponding openings.

[0026] By adopting the above technical solution, the massage tray frame is fixed above the mounting frame. The tray frame has two placement slots for the feet, separated by a dividing section to accommodate the left and right feet respectively, preventing interference between the feet during massage. The placement slots extend downwards from the top of the tray frame, with openings at the bottom. The massage roller assembly and scraping assembly are positioned corresponding to these openings. The massage protrusions of the massage roller assembly and the scraping assembly protrude through the openings from the bottom of the placement slots, directly contacting the soles of the feet for massage. The placement slots position and guide the feet, ensuring accurate alignment of the foot parts with the massage roller assembly and scraping assembly, resulting in precise and effective massage.

[0027] Compared with the prior art, the present invention has the following main beneficial effects, including but not limited to: a set of drive mechanisms simultaneously drives the massage wheel assembly to rotate and massage the toes and the scraping assembly to scrape the arch and heel in a straight line. The eccentric drive part on the massage wheel assembly converts the rotational motion into the linear reciprocating motion of the scraping seat, realizing the compound linkage of rotational massage and straight scraping. It has a compact structure, high transmission efficiency, and fully covers the entire sole of the foot. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0031] The following is combined with Figures 1 to 6 The technical solution of this utility model will be described in further detail below.

[0032] This embodiment provides a combined linkage mechanism for arch kneading and heel scraping. This combined linkage mechanism can be installed on the foot massage device at the front of the massage chair, corresponding to the human foot, and can massage the entire sole of the foot, including rotating and kneading massage of the toes and scraping massage of the arch and heel.

[0033] Please refer to the foot arch pinching and scraping and heel scraping combined linkage mechanism of this embodiment, which mainly includes a mounting frame 100, a drive mechanism 200, a massage roller assembly 300, and a scraping assembly 400. This combined linkage mechanism simultaneously drives the massage roller assembly 300 to rotate and massage the toes and the scraping assembly 400 to linearly scrape the arch and heel through a set of drive mechanisms 200, realizing the combined linkage of rotational massage and linear scraping.

[0034] Mounting frame 100 The mounting frame 100 serves as the foundation for the entire composite linkage mechanism. It is constructed from welded or bolted metal profiles, possessing sufficient structural strength and rigidity. Rotating seats 102 are fixedly mounted on both sides of the mounting frame 100, and are bolted to the mounting frame 100. Two connecting block seats 103 are provided on the mounting frame 100 corresponding to the positions of the scraping component 400, located on the left and right sides of the mounting frame 100 respectively. A groove frame 500 is fixedly mounted above the mounting frame 100. The groove frame 500 has two placement slots 501 for placing the user's feet, with a dividing section 502 between the two slots 501. The placement groove 501 extends downward from the top of the groove frame 500. An opening 503 is provided at the bottom of the placement groove 501. The massage roller assembly 300 and the scraping assembly 400 are positioned corresponding to the opening 503, allowing the massage parts 402 of the massage roller assembly 300 and the scraping assembly 400 to protrude through the opening 503 from the bottom of the placement groove 501 and contact the soles of the feet for massage. The back of the dividing section 502, corresponding to the bottom of the placement groove 501, is a hollow cavity, and the drive mechanism 200 is positioned corresponding to this hollow cavity.

[0035] Drive mechanism 200 The drive mechanism 200 is mounted on the mounting frame 100 and includes a drive motor 201, a turbine housing 203, and a drive shaft 202. The turbine housing 203 is fixedly mounted on the mounting frame 100 and is positioned in the hollow cavity on the back of the partition section 502 of the trough frame 500. The drive shaft 202 passes through the turbine housing 203, and a bearing 204 is provided between the drive shaft 202 and the turbine housing 203. The bearing 204 provides rotational support for the drive shaft 202 and reduces rotational friction. Both ends of the drive shaft 202 extend towards the massage roller assembly 300 and the scraping assembly 400 on both sides, respectively, and are rotatably mounted in the rotating seats 102 on both sides of the mounting frame 100. The rotating seats 102 provide stable support for both ends of the drive shaft 202.

[0036] A turbine 205 is housed within the turbine housing 203, and is fixedly mounted on the drive shaft 202, forming a single unit with it. A worm gear 206 is mounted on the output shaft of the drive motor 201, also located within the turbine housing 203 and connected to the turbine 205. When the drive motor 201 operates, the output shaft drives the worm gear 206 to rotate, which in turn drives the turbine 205 to rotate, which in turn drives the drive shaft 202 to rotate synchronously. The worm gear 206-turbine gear 205 transmission features smooth transmission, low noise, and a self-locking characteristic, preventing the massage roller assembly 300 from rotating in the reverse direction under the pressure of the user's foot when the drive motor 201 stops.

[0037] Massage roller assembly 300 The massage roller assembly 300 is mounted on the drive shaft 202 and rotates synchronously with the drive shaft 202. The massage roller assembly 300 includes a main massage roller 303 mounted on the drive shaft 202 and two side rollers 304 located on both sides of the main massage roller 303. The main massage roller 303 and the two side rollers 304 work together to massage the toe area of ​​the human foot.

[0038] The main massage roller 303 is fitted at the center of the drive shaft 202, and its outer circumference is unevenly distributed with multiple massage protrusions 302 of equal height. This uneven distribution design allows the massage protrusions 302 to press against the toes at irregular intervals during rotation, simulating the rhythmic feel of hand kneading. Two side rollers 304 are located on the left and right sides of the main massage roller 303, respectively. Each side roller 304 is fixedly connected to the drive shaft 202, ensuring that the side rollers 304 rotate synchronously with the drive shaft 202 without relative slippage. Each side roller 304 has massage protrusions 302 on its outer circumference. The massage protrusions 302 on the main massage roller 303 and the side rollers 304 alternately press and knead the toes from different angles, working together to complete a rotary kneading massage of the toes.

[0039] Each side roller 304 has an integrally formed eccentric wheel body 305 on the side closest to the main massage roller 303, and two eccentric wheel bodies 305 constitute an eccentric drive unit 301. Multiple protrusions 307 are provided on the outer circumferential surface of the eccentric wheel body 305, which increase the coefficient of contact friction between the eccentric wheel body 305 and the connecting part 401 of the scraping seat 408. Eccentric connecting parts 306 are provided on both sides of the main massage roller 303, and the eccentric connecting parts 306 are either eccentrically located on the two sides of the main massage roller 303 or extend outward from the two sides of the main massage roller 303. The eccentric connecting parts 306 are fixedly connected to the eccentric wheel body 305 of the corresponding side roller 304 by fasteners. Thus, the main massage roller 303, side rollers 304, and eccentric wheel bodies 305 are integrated into one unit, and the rotational motion of the drive shaft 202 is simultaneously transmitted to the main massage roller 303 and the eccentric wheel bodies 305.

[0040] Gua Sha Component 400 The gua sha assembly 400 includes a gua sha base 408, which has a connecting part 401 and a massage part 402. The connecting part 401 is located on the side of the gua sha base 408 near the massage roller assembly 300. The connecting part 401 has a ring structure and is fitted around the outer periphery of the eccentric wheel body 305 of the two side wheels 304. The protrusions 307 on the outer periphery of the eccentric wheel body 305 increase the contact friction with the inner wall of the connecting part 401 to prevent slippage. The massage part 402 is located on the side of the gua sha base 408 away from the massage roller assembly 300. The massage part 402 has massage protrusions 403 for gua sha massage of the arch and heel of the foot.

[0041] The massage section 402 on the scraping base 408 includes an arch massage area 405 and a heel massage area 406. The arch massage area 405 is located between the connecting part 401 and the heel massage area 406, and the heel massage area 406 is located on the side of the scraping base 408 away from the massage roller assembly 300. The heel massage area 406 is set lower than the arch massage area 405, corresponding to the position of the human heel, and the arch massage area 405 corresponds to the position of the human arch. This height difference design is adapted to the physiological curve of the human foot: the human arch is an upward arched arc, and the arch massage area 405 is higher, corresponding to the arched area of ​​the arch for scraping; the heel is a protruding circular area, and the heel massage area 406 is lower, corresponding to the heel area for scraping massage.

[0042] A scraping cover 407 is detachably mounted on top of the massage part 402, and massage protrusions 403 are provided on the scraping cover 407. The scraping cover 407 is fixedly connected to the massage part 402 of the scraping base 408 by fasteners. The scraping cover 407 and the massage part 402 are separate, and users can replace the scraping cover 407 with different hardness or different protrusion shapes according to their own massage needs. Furthermore, when the massage protrusions 403 on the scraping cover 407 wear down due to long-term use, only the scraping cover 407 needs to be replaced, without replacing the entire scraping base 408.

[0043] The scraping pad 408 is located below the arch massage area 405 and has guide grooves 404 on both its left and right sides. The guide grooves 404 are straight strips extending along the direction of movement of the scraping pad 408. A support shaft 101 is provided on the mounting frame 100 corresponding to the guide grooves 404, with both ends of the support shaft 101 connected between two connecting block seats 103. The support shaft 101 passes through the two guide grooves 404, providing guidance and limiting for the linear reciprocating motion of the scraping pad 408. The length of the guide grooves 404 limits the maximum stroke of the scraping pad 408, and the sliding fit of the support shaft 101 within the guide grooves 404 ensures that the scraping pad 408 can only move in a straight line along the extension direction of the guide grooves 404, without deflection or wobbling.

[0044] Work process When the drive motor 201 is working, the output shaft drives the worm gear 206 to rotate, the worm gear 206 drives the turbine 205 in the turbine housing 203 to rotate, and the turbine 205 drives the transmission shaft 202 to rotate around its own axis. The rotational motion of the transmission shaft 202 is simultaneously transmitted to the massage roller assembly 300 and the eccentric drive unit 301.

[0045] On one side of the massage roller assembly 300, the drive shaft 202 drives the two side rollers 304 and the main massage roller 303 to rotate synchronously. The non-uniformly distributed, equally high massage protrusions 302 on the outer circumference of the main massage roller 303 rotate with it, sequentially squeezing and kneading the toes; the massage protrusions 302 on the outer circumference of the two side rollers 304 assist in massaging the toes from the left and right sides. Together, the massage protrusions 302 on the main massage roller 303 and the side rollers 304 complete the rotational kneading massage of the toe area.

[0046] On one side of the scraping assembly 400, the eccentric wheels 305 on the two side wheels 304 rotate synchronously with the side wheels 304. The outer circumferential surface of the eccentric wheels 305 pushes the connecting part 401 of the scraping seat 408 sleeved on it, converting the rotational motion into the linear reciprocating motion of the scraping seat 408. Under the constraint of the support shaft 101 and the guide groove 404, the scraping seat 408 makes a linear reciprocating motion back and forth along the extension direction of the guide groove 404. The arch massage area 405 and the heel massage area 406 on the scraping seat 408 move back and forth together with the scraping seat 408. The arch massage area 405 performs a close-fitting scraping massage on the arch area of ​​the human foot, and the heel massage area 406 performs a scraping massage on the heel area of ​​the human foot. The height difference design of the arch massage area 405 and the heel massage area 406 allows the two massage blocks to apply pressure to the arch and heel respectively that matches the physiological structure of each part when they move back and forth.

[0047] A drive motor 201 simultaneously drives the massage roller assembly 300 and the scraping assembly 400. The massage roller assembly 300 rotates and kneads the toes, while the scraping assembly 400 performs back-and-forth scraping massage on the arch and heel. The two massage methods work together to fully cover the massage needs of the entire sole of the foot.

[0048] It should be understood that the above embodiments are merely illustrative examples and are not intended to limit the scope of this utility model. Based on the above embodiments, those skilled in the art can make appropriate adjustments and modifications to the dimensions and number of the main massage roller 303 and side rollers 304, the shape and distribution of the massage protrusions 302, the eccentricity of the eccentric wheel 305, the length and shape of the guide groove 404, the material and protrusion form of the scraping cover 407, and the transmission ratio of the turbine box 203, according to actual application requirements. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of the claims of this utility model should be included within the protection scope of this utility model.
