Description

Technical Field

[0001] The present invention relates to the field of massagers, and particularly to a handheld roller-type massager.

Background Art

[0002] The Chinese patent of Patent Document CN218338690U discloses a massage ball. In terms of its structure, it mainly includes a ball mechanism for rolling massage, a driving mechanism and a following mechanism connected to both sides of the ball mechanism. A rotating motor for driving the rotation of the entire ball mechanism is provided in the driving mechanism. The following mechanism only functions as an auxiliary handle and can rotate freely with respect to the ball mechanism and the driving mechanism. To use it for massage, it is necessary to hold the driving mechanism first and then use it. It is insufficient that the following mechanism cannot be used alone by holding it. That is, when the ball mechanism presses against the massage position and rotation occurs, only the force of one hand that resists the rotational torque of the driving mechanism can be used, resulting in a poor user experience for the user.

[0003] The Chinese patent of Patent Document CN308065631S discloses a roller-type massager in another structural form. The main difference from the above-mentioned document CN218338690U is that a connecting rod is installed between the handles on the left and right sides, whereby the left and right handles are connected as a single body. When massaging, both hands hold the handles on both sides, and both hands can resist the rotational torque, making it relatively labor-saving for the user to use. However, what is still lacking is that since the connecting rod is located on one side of the ball mechanism, a gap is formed between the ball mechanism and the connecting rod, which may entangle the user's clothes or accidentally injure the user. Therefore, there is still room for improvement in this type of rolling massage device.

Advantages of the Invention

[0020] Compared with the prior art, the beneficial effect of the present invention is that since the first handle and the second handle are connected to the bracket assembly in a removable manner, the main body part composed of the split bracket assembly and the roller massage assembly has a relatively short length, which is convenient for storage and carrying.

[0021] Next, the first end stand and the second end stand realize a relatively fixed connection through the end stand connecting pipe. Since the end stand connecting pipe penetrates through the inside of the roller massage assembly, a relatively fixed state is realized after the connection of the first handle, the second handle and the bracket assembly. On the other hand, compared with the case where the end stand connecting pipe is externally attached, a gap is formed between the end stand connecting pipe and the roller massage assembly, avoiding the case of being easily accidentally injured. In addition, the end stand connecting pipe provides a safe arrangement passage for the conductive wire.

[0022] Also, among the main components of the roller massager, as the motor and the battery that are relatively easy to be damaged and deteriorated, by respectively mounting them in the two handles, when problems such as damage to the motor due to improper use or excessive force, or deterioration of the battery occur, the corresponding handle can be replaced to continue using. Alternatively, when the massage time is long, two or more second handles with batteries can be prepared so that when the battery runs out, another second handle can be quickly replaced and continued to be used.

Embodiments for Carrying Out the Invention

[0024] As shown in Figures 1 to 15, this embodiment is a roller-type massager kit, comprising a roller-type massager 2, a bracket assembly 1 rotatably connected to the roller-type massager assembly, and a first handle 3 and a second handle 4 detachably connected to both ends of the bracket assembly.

[0025] As shown in Figure 5, the roller-type massage assembly includes two symmetrically positioned massage end stands 21, a polygonal tube 23 connected between the two massage end stands at an intermediate position, a plurality of connecting rods 24 connected between the two massage end stands, and a massage roller 26 rotatably fitted onto each connecting rod. In this embodiment, the massage roller 26 is composed of a plurality of massage beads rotatably fitted onto the connecting rods 24, which facilitates the manufacture of the massage beads and allows two or more different colored massage beads to be attached to a single roller-type massage assembly, resulting in a richer visual color scheme. The connecting rods are metal rods, or metal tubes 25 are fitted onto the outer walls of the connecting rods. In other embodiments, the massage roller may be an integrally injection-molded lever body having a plurality of longitudinally protruding massage portions, that is, having an external shape similar to a plurality of closely arranged massage beads.

[0026] The bracket assembly 1 includes a first end stand 12a and a second end stand 12b located on the left and right sides of the roller-type massage assembly, and an end stand connecting tube 10 that penetrates the inside of the roller-type massage assembly. The ends of the end stand connecting tube are fixedly connected to the first end stand and the second end stand, respectively, so that when the first handle and the second handle are connected to the bracket assembly, the first handle and the second handle are relatively fixed.

[0027] The first handle contains a motor 33 for rotating a roller-type massage assembly, and the motor is a reduction motor incorporating a planetary reduction gear group. The second handle contains a battery 44 for supplying power to the motor, and also includes conductive wires for electrically connecting the battery and the motor, the conductive wires passing through the end stand connecting pipe 10.

[0028] When using a handheld roller-type massager, the roller massage assembly presses against the muscles, and as the motor rotates, the bracket assembly receives torque in the opposite direction to the rotation of the roller massage assembly. The bracket assembly connects the first and second handles as a relatively fixed, integrated unit, allowing these handles to evenly distribute the torque transmitted from the bracket assembly. In this way, when the user grips the first and second handles with both hands and performs a massage, the force applied by both hands is even, resulting in a comfortable experience.

[0029] By combining Figures 3 and 4, the first and second end stands are each provided with a pipe fitting 120 that fits into the end portion of the end stand connecting pipe. One end of the end stand connecting pipe 10 and the pipe fitting 120 of the first end stand 12a are connected by screw fastening. Specifically, a screw is threaded radially into the pipe fitting 120 of the first end stand 12a, with the tip of the screw either tightly fixed to the outer wall of the end stand connecting pipe or a notch or through hole provided in the outer wall of the end stand connecting pipe through which the tip of the screw is inserted. After the screw is tightened, the first end stand 12a is fixed to the end stand connecting pipe in the circumferential and axial directions. In the end stand connecting pipe, a positioning groove 101 is provided at least at one end connected to the second end stand, and a positioning member is provided in the pipe joint of the second end stand that is inserted into the positioning groove, thereby fixing the second end stand and the first end stand circumferentially opposite the end stand connecting pipe. The positioning member may be a screw, a plug, or the like, and in this embodiment, the positioning member functions only for circumferential positioning of the second end stand relative to the end stand connecting pipe. In this embodiment, positioning grooves are provided at both ends of the end stand connecting pipe, and the bottom of the positioning groove is provided in the notch or through hole so that the screw of the pipe joint 120 of the first end stand 12a can be easily aligned with the notch or through hole.

[0030] The bracket assembly further comprises a hollow screw 16 coaxially connected to the end stand connecting pipe, and after the roller-type massage assembly is mounted between the first end stand and the second end stand, the hollow screw fixes the second end stand and the end stand connecting pipe axially, and the conductive wire passes through the hollow screw. By improving the connection method between the end stand connecting pipe and the first and second end stands, this bracket assembly prevents the bracket assembly from interfering with the rotation of the roller-type massage assembly, avoids unexpected situations such as winding or pinching due to the external mounting of the end stand connecting pipe, and facilitates the arrangement of the conductors between the motor and the battery.

[0031] As shown in Figure 8, the end stand connecting pipe 10 is a metal pipe with a non-circular end face, specifically a hexagonal stainless steel pipe, and the first end stand 12a and the second end stand 12b are each provided with a pipe joint 120 that is inserted into or fitted to the end portion of the end stand connecting pipe 10, and after the first end stand and the second end stand are connected to both ends of the end stand connecting pipe, the second end stand is fixed to the first end stand in the circumferential direction. A tightening screw 18 and a tightening nut that screws onto the tightening screw are further connected between the first end stand 12a and the second end stand 12b. The tightening screw passes through the end stand connecting pipe, and after the tightening screw and the tightening nut are screwed together, the first end stand, the end stand connecting pipe, and the second end stand are fixed relative to each other in the axial direction.

[0032] Combining Figures 3, 6, and 7, an internal gear 211 is provided at one end of the roller-type massage assembly, two or more planetary gears 15 are provided on the first end stand and meshed with the internal gear, a first end cover 13a is further connected to the first end stand, the first end cover is provided with an insertion portion 130 that is inserted into the first handle, a gear bracket 132 is provided at the bottom of the insertion portion, a drive gear 14 is rotatably connected to the gear bracket, and the drive gear is meshed with the planetary gear.

[0033] Specifically, the two massage end stands on either side of the roller-type massage assembly have exactly the same structure, and the internal gear 211 is provided on the outer inner circumference of both. Thus, there is no need to distinguish between the left and right ends of the roller-type massage assembly when connecting it to the bracket assembly, and the fact that the two massage end stands have the same structure is convenient for manufacturing. As shown in Figure 7, there are two notches at the position where the planetary gear 15 is mounted on the first end stand so that the planetary gear can mesh and transmit with the internal gear 211. Similarly, as shown in Figure 6, the gear bracket is generally U-shaped, and notches are formed on both sides of the gear bracket to expose the outer circumference of the drive gear 14, so that the drive gear can mesh and transmit with the two planetary gears, respectively.

[0034] As shown in Figures 7 and 9, a transmission sleeve 141 is provided at the rear end of the drive gear, transmission teeth 142 are provided on the inner wall of the transmission sleeve at equal angles in the circumferential direction, a drive plug 34 is coaxially connected to the output shaft of the motor, drive teeth are provided on the outer wall of the drive plug at equal angles in the circumferential direction, after the first handle is inserted into the insertion part on the first end cover, the transmission sleeve is coaxially transmitted and inserted into the drive plug, the end portions of the drive teeth and transmission teeth are both provided with inclined guide surfaces, the guide surfaces allow the drive teeth to be forcibly rotated between the drive teeth and the drive gear via the guide surfaces, and the drive teeth can be inserted between adjacent transmission teeth so that the drive plug can rotate the drive gear synchronously.

[0035] As shown in Figure 6, the second end stand 12b is connected to the second end cover 13b, and the second end cover is provided with an insertion part 130 that is inserted into the second handle. A pair of electrical connection plugs 17 are attached to the inner bottom of the insertion parts of the first end stand and the second end stand, each pair of electrical connection plugs contains two plugs, and the two pairs of electrical connection plugs are electrically connected by a flexible conductive wire.

[0036] A stud is provided at the tail end of the electrical connection plug, a fixing hole is provided at the inner bottom of the insertion part for inserting the stud, a nut is connected to the stud for fixing the electrical connection plug to the inner bottom of the insertion part, an electrode sheet is connected to the end of the conductive wire, and the electrode sheet is tightened between the nut and the insertion part.

[0037] Combining Figures 9 and 10, the first handle includes a tubular first handle housing 31, to which a first handle back cover 37 is connected at one end, and the other end of the first handle housing is a plug detachably connected to a bracket assembly, a multi-function mounting frame 32 is inserted into the plug and in the portion of the first handle housing adjacent to the plug, the motor is connected to the multi-function mounting frame 32 at one end away from the plug, the multi-function mounting frame is provided with a pair of socket storage grooves 321, an electrical connection socket 36 electrically connected to the motor via conductive wires is mounted in the socket storage grooves, the multi-function mounting frame is inserted into the plug, and the electrical connection socket is fixed in the socket storage grooves. After the plug is inserted into the insertion portion, the electrical connection socket 36 is abutted against the corresponding electrical connection plug 17 and electrically connected, making the conductive wires conductive.

[0038] The side wall of the multi-functional mounting frame is provided with two locking device storage grooves 322, and one elastic locking device 35 is installed in each locking device storage groove. A locking device through hole is provided on the side wall of the plug-in plug at a position corresponding to the locking device storage groove, which is used for the protrusion of the elastic locking device. The elastic locking device includes a locking device body and a spring provided between the locking device body and the bottom of the locking device storage groove. The locking device through hole is slightly smaller than the locking device storage groove, so that after the elastic locking device is installed in the locking device storage groove, only a portion of the outer wall of the locking device is exposed, and the remaining portion is located inside the locking device storage groove, preventing it from coming out.

[0039] The multi-functional mounting bracket can fix the motor 33, and by engaging with the plug side wall, it can also fix the electrical connection socket 36 and the elastic locking device 35. Furthermore, when the multi-functional mounting bracket is inserted into the plug, it provides a reinforcing effect on the plug.

[0040] As shown in Figure 6, the insertion side wall of the first end cover 13a is provided with locking holes 131 that engage with the two elastic locking devices 35, and button mounting holes 122 are provided on the first end stand side wall at positions corresponding to each locking hole, and one release button 11 is slid into each button mounting hole, and when the release button is pressed to its limit position, the inner end of the release button retracts until the outer end of the elastic locking device at the corresponding position is parallel to the outer wall of the insertion plug, thereby releasing the elastic locking device from the locking holes 131. The insertion plug can only be pulled out of the insertion part when the two elastic locking devices have released from the locking holes at their corresponding positions.

[0041] A similar connection structure is employed between the second handle and the second end cover. Two relatively independent release buttons are provided to unlock each of the two elastic locking mechanisms, so that even if one release button is accidentally touched, the first or second handle and the bracket assembly will not detach unexpectedly, preventing damage to the massager or unexpected injury to the user.

[0042] As shown in Figure 11, the second handle includes a tubular second handle housing 41, to which a rear end cover 43 is connected at one end of the second handle housing, and the other end of the second handle housing is a plug detachably connected to a bracket assembly, to which an inner bracket 42 is connected, and a circuit board for controlling the operation of the motor is connected inside the rear end cover, and the circuit board is equipped with a charging port, a power switch, etc. Such a circuit board generally includes a charging module and a speed control module, which is mature prior art and not the focus of the present invention, and will not be discussed further in this text.

[0043] A set of socket storage grooves is provided on the side wall of the inner bracket, and an electrical connection socket, which is electrically connected to a circuit board via conductive wires, is installed in the socket storage grooves. After the inner bracket is inserted into the plug, the electrical connection socket is fixed in the storage grooves.

[0044] As shown in Figures 12 to 14, the roller-type massager includes a storage seat 5, the storage seat comprising one connecting seat 51 and two support seats 52 connected to both sides of the connecting seat, the support seats being provided with end stand support portions 520, the end stand support portions being provided with positioning ribs 5201, and the outer walls of the first and second end stands being provided with storage seat positioning grooves 121 that engage with the positioning ribs to position the storage seat, thereby preventing the first end stand 12a and the second end stand 12b from rotating relative to the end stand support portions after they are placed on the two end stand support portions. Specifically, the outer walls of the first and second end stands are generally cylindrical, the shape of the end stand support portions conforms to the shape of the outer walls of the first and second end stands, and position limiting edges 5202 are provided on the outside of the end stand support portions to prevent the first and second end stands from sliding away from the end stand support portions.

[0045] The two support seats 52 are rotatably connected to the connecting seat 51, and the support seats have an extended state (Figure 12) and a folded state (Figure 14) relative to the connecting seat. When the support seats are in the extended state relative to the connecting seat, the first end stand and the second end stand can be fixedly placed on the end stand support portions of the two support seats. In this state, it is suitable for performing a foot massage by stepping on the roller massage assembly 2 or for massaging the leg muscles by placing the leg on the roller massage assembly.

[0046] When the support seat is folded relative to the connecting seat, a positioning cavity is formed between the two support seats 52 and the connecting seat 51, which can house and secure at least the first handle 3 and the second handle 4. The positioning cavity includes a storage groove 513 provided in the connecting seat and a handle positioning notch 522 provided in the support seat.

[0047] The aforementioned storage base not only reduces in length to facilitate packaging and transport, but is also foldable and designed to accommodate the first and second handles, making the overall space of the roller massager smaller and convenient for fitness users to carry when going out.

[0048] A positioning mechanism is further provided between the connecting seat and the support seat to enable relative fixing of the support seat and the connecting seat when they are in a folded state. Specifically, in this embodiment, the connecting seat is provided with a locking device mounting opening 512 to which a locking device 53 is attached, and the support seat is provided with a locking device mounting opening that engages with the locking device. In another embodiment, magnets are attached to the connecting seat 51 and the support seat 52 at corresponding positions, and when the support seat is folded relative to the connecting seat, the magnets on the support seat and the connecting seat attract each other.

[0049] As shown in Figure 15, symmetrical notches are provided on both the left and right sides of the connecting seat, and a rotating lever 511 is provided in the notches. On one side of the support seat adjacent to the connecting seat, a rotating engagement port 521 is provided that engages with the rotating lever and rotates to connect to the rotating lever. In this embodiment, the connecting seat and support seat are all made of plastic material, the rotating lever and connecting seat can be designed as an integrally molded structure, and the rotating engagement port can directly engage with the rotating lever to form a rotating connection. As a result, there are few assembly structural parts, and manufacturing and assembly are relatively convenient.

[0050] When in use, the first handle 3 is inserted into the insertion portion 130 of the first end cover 13a, and when the elastic locking device 35 engages with the locking opening 131, the elastic locking device pushes out the release button 11, and the outer end of the release button can be seen protruding from the outer wall surface of the first end sheet 12a. Next, the second handle 4 is inserted into the insertion portion of the second end cover 13b. The first handle has a drive plug 34 and the first end cover has a drive sleeve 141 that is alignably connected to it, and the second handle does not have a drive plug and cannot be inserted into the second end cover, so there is no problem of the first handle or second handle being inserted in the wrong position.

[0051] After the first and second handles are connected in their designated positions, simply by turning on the power switch, the motor 33 transmits power to the internal gear 211 sequentially via the drive plug 34, drive gear 14, and planetary gear 15, thereby rotating the entire roller-type massage assembly 2 relative to the bracket assembly 1. At this time, gripping one or both of the first and second handles allows for rolling and massaging the muscles of various parts of the body.

[0052] If you need to massage the muscles of your feet or legs, unfold the storage seat 5 to the state shown in Figure 12, place the first end stand 12a and the second end stand 12b on the support seats 52 on both sides of the storage seat 5, ensuring that the storage seat positioning groove 121 is just hooked onto the positioning rib 5201, and then you can sit on the chair and step on the roller massage assembly 2 to massage your soles, or sit or lie on the mat and place your legs on the roller massage assembly 2 to massage them.
