Hereinafter, referring to the drawings, the massage device 1000 having the rotatable arm massage unit according to an embodiment of the present invention will be described in detail.
Hereinafter, as will be described below, providing a massage to the user's arm should be understood not only as providing a massage (e.g., pressing massage (or acupressure), tapping massage, kneading massage, etc.), but also as including at least one of various actions of the arm massage unit 1200 provided to the user's arm, that is, stretching performed by rotating or expanding the user's arm in a specific direction, and other medical treatments.
Furthermore, the arm massage unit 1200 can also provide a function that minimizes interference between the arm massage unit 1200 and the user's body by rotating at least in one direction when the user sits in the body massage unit 1100 or stands up after using, thereby facilitating the user's seating or standing up from the body massage unit 1100. For instance, just before the user sits in the body massage unit 1100 or just before the user stands up from the body massage unit 1100, a rotation module can rotate both or one side of the arm massage unit 1200 upwards to open at least one side of the body massage unit 1100, making the seating or standing-up motion more convenient. The arm massage unit 1200 can be placed on both sides of the body massage unit 1100. For example, the arm massage units 1200 can be respectively placed in positions (or areas) corresponding to the user's arms over the entire bilateral area of the body massage unit 1100. Each arm massage unit 1200 may have a space to accommodate the user's arm.
The arm massage unit 1200 may include an arm massage unit frame 1210 connected to both sides of the main frame 1130. The arm massage unit frame 1210 can rotate vertically around a rotational shaft 1230 installed on both sides of the main frame 1130. The rotational shaft 1230 can be placed near one end (or the upper end) of the upper frame 1131. In this case, both top ends of the upper frame 1131 correspond to the user's shoulders, and may correspond to the upper rear of the user's shoulders. The rotational shaft 1230 can be directly connected to the upper portion of the upper frame 1131 near the user's bilateral shoulder rear or can be connected to the upper frame via a bracket, or a plate or a frame structure, and can rotate around an axis extending laterally from the top of the upper frame 1131.
An armrest frame support 1212 having a ‘C’-shaped armrest recess 1213 which is opened to the side interior and the rear may be provided on the front side of the arm massage frame 1210. A ‘C’-shaped armrest frame 1214 into which a user's arm is inserted and mounted may be installed inside the armrest recess 1213 of the armrest frame support 1212. The armrest frame 1214 may be formed in a ‘C’ shape corresponding to the armrest recess 1213. Inside the armrest frame 1214, at least one of an air cell, a massage module, and a heating module for massaging the user's arm may be included. The air cell can massage the user's arm area by expanding and contracting through air supply and discharge, the massage module is configured to vibrate the arm area by an actuator, and the heating module is configured to provide a massage effect by applying heat to the arm area.
The arm massage frame 1210 can rotate vertically around the rotational shaft 1230 by the rotation module 1270. At this time, as illustrated in
Such a positional difference, when the arm massage unit 1200 rotates, may cause the user's arm to be excessively pulled, leading to excessive stretching, or exert a force that contracts the user's arm, so may cause discomfort or pain for the user. Therefore, based on the rotational angle of the arm massage unit 1200, the arm massage unit 1200 can naturally linearly move regarding the rotational shaft 1230, and alter the rotation trajectory of the end of the arm massage unit 1200.
In other words, as illustrated in
The position adjustment module 1250 is configured to allow the arm massage unit frame 1210 of the arm massage unit 1200 to linearly move by sliding relative to the rotational shaft 1230 while simultaneously rotating around the rotational shaft 1230. In other words, the position adjustment module 1250 enables the arm massage unit 1200 to linearly move while sliding relative to the rotational shaft 1230 when the arm massage unit 1200 rotates around the rotational shaft 1230 to adjust the distance between the end of the arm massage unit 1200 and the body massage unit 1100.
In one embodiment, the position adjustment module 1250 may include an shaft coupling member 1251 coupled to the rotational shaft 1230, and a guide part 1255 enabling the arm massage unit 1200 to linearly move by sliding relative to the shaft coupling member 1251 but preventing relative rotation.
The guide part 1255 includes a guide hole 1257, which is elongated on the arm massage unit 1200 in one direction so that the shaft coupling member 1251 is connected in such a way as to be slidable but to be prevented in relative rotation. The guide hole 1257 may be formed in a guide plate 1256 which is fixed to the rear side of the arm massage unit frame 1210. While the guide plate 1256 may be fabricated separately from the arm massage unit frame 1210 and subsequently attached to the arm massage unit frame 1210. Alternatively, the guide plate 1256 may be made of materials which are the same as or different from the arm massage unit frame 1210 to be formed integrally with the arm massage unit frame 1210.
The shaft coupling member 1251 may be installed by being slidably inserted into the inside of the guide hole 1257. Around the approximate center of the shaft coupling member 1251, an shaft coupling hole 1252, through which the rotational shaft 1230 passes, is laterally penetrated. Flanges around the shaft coupling hole 1252 and around the rotational shaft 1230 can be joined by fastening means, such as bolts, so that the shaft coupling member 1251 and the rotational shaft 1230 can rotate together. The shaft coupling member 1251 can be coupled to the guide hole 1257 of the guide plate 1256 in a manner that allows sliding in the length direction but prevents relative rotation. Therefore, when the rotational shaft 1230 rotates by the rotation module 1270, the shaft coupling member 1251 coupled to the rotational shaft 1230 also rotates. At this time, the arm massage unit frame 1210 can also rotate with the shaft coupling member 1251. As the arm massage unit frame 1210 rotates with the shaft coupling member 1251, when the arm massage unit 1200 receives a forward or backward force due to the self-weight, the arm massage unit frame 1210 can slide while being guided by the guide hole 1257 and the shaft coupling member 1251 such that the arm massage unit frame 1210 can move naturally linearly in the back-and-forth direction (or in the length direction) relative to the rotational shaft 1230.
In a state in which the user's arm is inserted into the armrest frame 1214 at the front of the arm massage unit frame 1210, when the rotational shaft 1230 rotates upwards by the rotation module 1270 and the arm massage unit frame 1210 also rotates upwards, the arm massage unit 1200 experiences a force to move downwards due to the self-weight, such that the arm massage unit 1200 can move linearly in the backward direction. Specifically, the arm massage unit frame 1210 slides backward while being guided by the guide hole 1257 and the shaft coupling member 1251, thereby enabling the arm massage unit frame 1210 to move linearly backward. Accordingly, the arm massage unit 1200 can be naturally adjusted to a user-preferred position, so that the airbag of the arm massage unit 1200 can be positioned corresponding to the user's arm.
On the contrary, after the arm massage unit 1200 is rotated upward, when being rotated downward to return to its initial state, the arm massage unit 1200 can move linearly in the forward direction. Specifically, the arm massage unit frame 1210 slides forwards while the guide hole 1257 of the arm massage unit frame 1210 is guided by the shaft coupling member 1251, so that the arm massage unit frame 1210 moves linearly forward.
To prevent shaking while the arm massage unit frame 1210 is guided by the shaft coupling member 1251 and slides in the back-and-forth direction and as soon as rotating vertically by the shaft coupling member 1251, and to allow the arm massage unit frame 1210 to slide smoothly relative to the shaft coupling member 1251, the guide part 1255 may further include a rail groove 1256a formed on the arm massage unit 1200 to be parallel to the length direction of the guide hole 1257, and a rail protrusion 1251b formed on the shaft coupling member 1251 formed to slide along the rail groove 1256a. For example, the guide plate 1256 may have a rail groove 1256a formed parallel to the guide hole 1257, and at least one rail protrusions 1251b protruding from at least one of both wing portions 1251a of the shaft coupling member 1251 to slide along the inner face of the rail groove 1256a. Conversely, the rail groove may be formed on the shaft coupling member 1251, and the rail protrusion may be formed on the guide plate 1256 of the arm massage unit frame 1210.
As described above, in order to reduce the load applied to the arm massage unit frame 1210 when the arm massage unit frame 1210 slides and moves linearly with respect to the shaft coupling member 1251 in conjunction with the rotational action of the arm massage unit frame 1210, the position adjusting module 1250 may further include a cushioning member 1258 which provides elasticity to the arm massage unit frame 1210 with respect to the shaft coupling member 1251.
The cushioning member 1258 has one end connected to the shaft coupling member 1251 and the other end connected to the arm massage unit frame 1210, thereby providing an elastic force to the arm massage unit frame 1210 relative to the shaft coupling member 1251 to provide a cushioning action when the arm massage unit frame 1210 slides with guidance from the guide hole 1257 and the shaft coupling member 1251. In one embodiment, the cushioning member 1258 may be one or more gas cylinders filled with gas or having a built-in spring. In another embodiment, the cushioning member 1258 may be composed using a spring. In a case that multiple gas cylinders are applied as the cushioning member 1258, one end of the gas cylinder may be connected to the arm massage unit frame 1210 by the cylinder bracket 1259.
The rotation module 1270, which rotates the arm massage unit 1200 vertically relative to the main frame 1130, can be configured to rotate the shaft coupling member 1251 by transmitting rotational force to the rotational shaft 1230 and to rotate the arm massage unit frame 1210 by the rotation of the shaft coupling member 1251. Referring to
The motor 1271 is installed on one side (in this embodiment, the upper end) of the module frame 1279, and can operate by receiving power from the control unit 1400 of the massage device (see
The first worm gear 1272 is axially coupled to the motor 1271 and can rotate by receiving rotational force from the motor 1271.
The first worm wheel 1274 and the second worm gear 1275 are provided on both ends of the rotational force transmission shaft 1273, and can rotate together with the rotational force transmission shaft 1273. The rotational force transmission shaft 1273 can be freely rotatably installed on the module frame 1279 through bearings 1278.
The first worm wheel 1274 is provided at one end of the rotational force transmission shaft 1273, and meshed with the first worm gear 1272 to receive the rotational force from the first worm gear 1272. The second worm gear 1275 is provided at the other end of the rotational force transmission shaft 1273, and meshed with the second worm wheel 1276 coupled to the rotational shaft 1230 to transmit the received rotational force to the second worm wheel 1276.
The second worm wheel 1276 is positioned on the external circumferential part of the rotational shaft 1230, and rotates upon receiving rotational force from the second worm gear 1275. At this time, the second worm wheel 1276 can be coupled to the external circumferential part of the rotational shaft 1230 by a coupling member (for example, an adhesive, screws, and the like).
Therefore, when the motor 1271 receives power from the control unit 1400 (see
The rotation module 1270, which includes the first worm gear 1272, the first worm wheel 1274, the second worm gear 1275, and the second worm wheel 1276, can prevent the arm massage unit 1200 from falling and causing an accident in the event of an emergency where the power supply to the motor 1271 is cut off during the rotational operation of the arm massage unit 1200.
In other words, since the worm gears and the worm wheels forms a power transmission mechanism that cannot transmit power through reverse rotation, if the power supplied to the motor 1271 is cut off and the motor 1271 stops operation, even if the arm massage unit 1200 is subjected to a downward load due to its self-weight, the first worm gear 1272, the first worm wheel 1274, the second worm gear 1275, and the second worm wheel 1276 will not transmit rotational force. As a result, the arm massage unit 1200 can maintain its stationary state without rotation and falling.
Furthermore, even if an unintended external force is applied to the arm massage unit 1200 in a direction opposite to the rotational direction, the first worm gear 1272, the first worm wheel 1274, the second worm gear 1275, and the second worm wheel 1276 can prevent the arm massage unit 1200 from rotating in the opposite direction.
In the massage device according to the described embodiment, as the rotational shaft 1230 is rotated by the rotation module 1270, the arm massage unit 1200 rotates around rotational shaft 1230. Depending on the rotation angle of the arm massage unit 1200, due to the self-weight, the arm massage unit 1200 can slide along the shaft coupling member 1251 coupled to the rotational shaft 1230, so that the arm massage unit 1200 can move naturally in the forward and backward direction (or lengthwise) and the position of one end of the arm massage unit 1200 can be adjusted.
Therefore, when performing stretching or massage motions by rotating the arm massage unit 1200, the position of one end of the arm massage unit 1200 relative to the body massage unit 1100 can be naturally adjusted without using any actuator or driving device for moving the arm massage unit 1200, thereby allowing the airbag provided in the arm massage unit 1200 to be adjusted to the user's preferred position.
When the position of one end of the arm massage unit 1200 relative to the body massage unit 1100 is adjusted, the user's arm can be rotated without excessive stretching or strain. Therefore, the present invention can prevent arm injuries, overcome the issue of the arm detaching from the arm massage unit 1200, and safely perform arm stretching actions.
Additionally, through the cushioning member 1258, the arm massage unit 1200 is prevented from sliding excessively, thereby improving durability, reducing noise, and enhancing accuracy and stability in movement of the arm massage unit 1200. Accordingly, consumers' satisfaction with the massage device can be improved.
In the massage device 1000 of this embodiment, the arm massage unit frame 1210 constituting the arm massage unit 1200 does not move forward and backward relative to the rotational shaft 1230. When the arm massage unit frame 1210 rotates around the rotational shaft 1230, the armrest frame 1214 installed on the front side of the arm massage unit frame 1210 can slide in the back-and-forth direction to be automatically adjusted in position.
For example, the massage device 1000 of this embodiment may include a position adjustment module 1260 which adjusts the position of the armrest frame 1214 by synchronizing with the rotational action of the arm massage unit 1200 so that linear movement of the arm massage unit 1200 in the back-and-forth direction by self-weight occurs.
The position adjustment module 1260 may include a position adjustment rail 1261 installed to extend in the back-and-forth direction on the inner side of the armrest groove 1213 of the armrest frame support 1212, an armrest frame 1214 which moves along the position adjustment rail 1261 when the arm massage frame 1210 rotates around the rotational shaft 1230, and a frame cushioning member 1264 which provides an elastic force to the armrest frame 1214 in the back-and-forth direction relative to the armrest frame support 1212 when the armrest frame 1214 moves along the position adjustment rail 1261.
The arm massage unit 1200 may include an arm massage frame 1210 connected to both sides of the main frame 1130. The arm massage frame 1210 can rotate vertically around the rotational shaft 1230 installed on both sides of the main frame 1130. As in the described embodiment, the rotational shaft 1230 can be positioned near one end (or upper end) of the upper frame 1131. At this time, both upper ends of the upper frame 1131 can correspond to the user's shoulders, such as the top rear of both shoulders of the user. The rotational shaft 1230 can be directly connected to the upper portion of the upper frame 1131 near the user's bilateral shoulder rear or can be connected to the upper frame via a bracket, or a plate or a frame structure, and can rotate around an axis extending laterally from the top of the upper frame 1131.
The arm massage frame 1210 can rotate vertically around the rotational shaft 1230 by the rotation module 1270. The rotation module 1270 has the structure and operation which are identical or similar to those of the rotation module 1270 described with reference to
A ‘C’-shaped armrest frame 1214 into which a user's arm is inserted and mounted may be installed inside the armrest recess 1213 of the armrest frame support 1212 to move in the back-and-forth direction or in the length direction by being guided by a position adjustment rail 1261. The armrest frame 1214 may be formed in a ‘C’ shape corresponding to the armrest recess 1213. Inside the armrest frame 1214, at least one of an air cell, a massage module, and a heating module for massaging the user's arm may be included. The air cell can massage the user's arm area by expanding and contracting through air supply and discharge, the massage module is configured to vibrate the arm area by an actuator, and the heating module is configured to provide a massage effect by applying heat to the arm area.
On the lower surface of the armrest frame support 1212, an armrest lower frame 1215 having the position adjustment rail 1261 may be installed. The armrest lower frame 1215 can have a rectangular shape with an open top surface. Within the internal space of the armrest lower frame 1215, one or more position adjustment rails 1261 may be installed to extend in the back-and-forth direction or in the length direction. The position adjustment rail 1261 may have a polygonal bar shape like a rectangle or a circular bar. Additionally, the position adjustment rail 1261 may also be constructed using a linear guide rail (LM guide rail), slide rail, etc.
The armrest frame 1214 can be connected to the position adjustment rail 1261 through a rail connection member 1262 to slide along the position adjustment rail 1261. The rail connection member 1262 can be coupled to the lower surface of the armrest frame 1214 and accommodated within an inner space of the armrest lower frame 1215 to move in the length direction by being guided by the position adjustment rail 1261. Furthermore, the rail connection member 1262 may have an approximate cuboid shape having a guide groove 1263 formed to correspond to the position adjustment rail 1261. For instance, the rail connection member 1262 can move stably by being guided by the position adjustment rail 1261 inserted into the guide groove 1263.
The armrest frame 1214 or the rail connection member 1262 can be connected to the frame cushioning member 1264. The frame cushioning member 1264 operates in conjunction with the rotating movement of the arm massage unit frame 1210 to elasticity to the armrest frame 1214 against the armrest frame support 1212 when the armrest frame 1214 slides and linearly moves relative to the position adjustment rail 1261, thereby reducing the load applied to the armrest frame 1214.
The frame cushioning member 1264 can be accommodated within the internal space of the armrest lower frame 1215. At this time, the frame cushioning member 1264 may be a gas cylinder or a spring of which one end is connected to the armrest lower frame 1215, and the other end is connected to the armrest frame 1214 or the rail connection member 1262.
According to this embodiment, as the rotational shaft 1230 rotates by the rotation module 1270, the arm massage unit frame 1210 rotates around the rotational shaft 1230. Depending on the rotation angle of the arm massage unit frame 1210, the armrest frame 1214 slides while being guided by the position adjustment rail 1261 due to the self-weight of the armrest frame 1214, so that the arm massage unit 1200 naturally moves in the back-and-forth direction relative to the rotational shaft 1230, thereby automatically adjusting the position of the armrest frame 1214.
In this instance, the frame cushioning member 1264 provides elasticity in the opposite direction to the movement direction of the armrest frame 1214 to reduce the movement speed of the armrest frame 1214, so that the armrest frame 1214 can move smoothly within the armrest groove 1213.
Referring to
For instance, as illustrated in
In addition, a guide groove 1263, into which the position adjustment rail 1261 is inserted and guided may be formed on a rail connection member 1262 coupled to the bottom surface of the armrest frame 1214 (see
The fixation protrusion 1292, due to the elasticity of the elastic body 1293, may be caught to the concavo-convex portion 1291 by receiving elasticity from the rail connection member 1262 towards the support sub-frame 1215. The user can position the armrest frame 1214 at a comfortable position due to the concavo-convex portion 1291 and the fixation protrusion 1292 provided on the rail connection member 1262. That is, the user makes the fixation protrusion 1292 caught to another groove included in the concavo-convex portion 1291 by applying force in the back-and-forth direction or in the length direction, thereby easily adjusting the position of the armrest frame 1214 to a desired position.
Therefore, when the arm massage unit 1200 rotates around the rotational shaft 1230 and the entire arm massage unit frame 1210 linearly moves relative to the rotational shaft 1230 adjusting the position of the arm massage unit frame 1210, when the user pushes the armrest frame 1214 forward or pulls the armrest frame 1214 backward, the fixation protrusion 1292 can move over the protrusions and indentations of the concavo-convex portion 1291 and the armrest frame 1214 is fixed at the desired position, so that the position can be adjusted.
Alternatively, as illustrated in
For example, a position adjustment rail 1261 which guides the rail connection member 1262 in the back-and-forth direction and a rack gear 1296 may be installed to extend in the back-and-forth direction within the support sub-frame 1215 installed on the bottom surface of the armrest frame support 1212 (see
In a case in which the back-and-forth position of the armrest frame 1214 is adjusted by using the position adjustment motor 1295, the pinion gear 1297, and the rack gear 1296, the position adjustment rail 1261 may be omitted.
Meanwhile, when the arm massage unit 1200 of the massage device rotates upwards around the rotational shaft 1230, a space is formed between the lower portion of the arm massage unit 1200 and the side of the body massage unit 1100. Through the space, a pet or a child may enter, and, in this instance, when the arm massage unit 1200 rotates downwards, an accident (for example, jam in the arm massage unit) may occur.
To prevent such an accident, as illustrated in
For instance, the side shields 1281, 1282, and 1283 may include a lower side shield 1281 coupled to one side of the body massage unit 1100, an upper side shield 1282 coupled to the arm massage unit 1200 and moving with the arm massage unit 1200, and a middle side shield 1283 connected between the lower side shield 1281 and the upper side shield 1282 to move vertically.
The lower side shield 1281 can be fixed to a side plate 1102 installed on the side of the body massage unit 1100. The lower side shield 1281 can be coupled to the side plate 1102 to prevent the side plate 1102 from being separated to the outside.
The top of the upper side shield 1282 can be fixed to at least one of the bottom or the side of the frame 1210 of the arm massage unit 1200.
The middle side shield 1283 can be slidably installed between one side (for example, the outer side) of the lower side shield 1281 and one side (for example, the inner side) of the upper side shield 1282.
The lower side shield 1281 and the upper side shield 1282 respectively have a lower guide hole 1284 and an upper guide hole 1285 which are formed in an arc shape to extend vertically, and a lower towing pin 1287 and an upper towing pin 1286 which are respectively inserted and guided into the lower guide hole 1284 and the upper guide hole 1285 are respectively provided on the upper portion and the lower portion of the middle side shield 1283.
When the arm massage unit 1200 rotates upward, the upper side shield 1282 may rotate upward together with the arm massage unit 1200. At this time, if the bottom of the upper guide hole 1285 is caught to the upper towing pin 1286 of the middle side shield 1283, the middle side shield 1283 is towed and moved upward, and spread out. In this instance, the lower towing pin 1287 of the middle side shield 1283 may be guided while moving along the lower guide hole 1284.
In this manner, the lower side shield 1281, the middle side shield 1283, and the upper side shield 1282 can spread out while sliding in relation to each other, so as to shield the space between the bottom of the arm massage unit 1200 and the side of the body massage unit 1100, thereby preventing an accident, such as a pet or a child getting caught.
As the arm massage unit 1200 rotates downward, the folding process of the lower side shield 1281, the middle side shield 1283, and the upper side shield 1282 can be performed in reverse of the aforementioned procedure.
In this embodiment, one middle side shield 1283 is placed between the lower side shield 1281 and the upper side shield 1282. However, according to circumstances, the middle side shield 1283 may not be provided, or two middle side shields 1283 may be provided.
Furthermore, one or more side shields in a corrugated shape or a bellows shape may be configured to fold or unfold according to the rotation of the arm massage unit 1200, thereby easily shielding the space between the bottom of the arm massage unit 1200 and the side of the body massage unit 1100. In addition, various foldable shield structures may be applied to the side shields. Meanwhile, as illustrated in
The leg massage units 1300 can be provided to correspond to both legs of the user. For instance, the leg massage units 1300 may include a first leg massage unit 1310, which corresponds to one leg of the user, and a second leg massage unit 1330, which corresponds to the other leg of the user.
The first leg massage unit 1310 and the second leg massage unit 1330 can be controlled independently. For example, the first leg massage unit 1310 and the second leg massage unit 1330 can individually provide a massage function to the user. Additionally, the first leg massage unit 1310 and the second leg massage unit 1330 can rotate independently. As occasion demands, the user may receive different massages on each leg or receive a massage on both legs alternatingly. Additionally, the user may receive stretching or massages on both legs due to rotation. In this case, the first leg massage unit 1310 and the second leg massage unit 1330 may rotate both legs of the user simultaneously or individually.
