Description

Technical Field

[0001] The utility model relates to a body correction device, in particular to a body correction stick with a telescopic rotating pillow with gear positions, which is used for opening shoulders, beautifying backs and correcting standing postures. Background Art

[0002] The body stick, also known as the back-opening stick, standing posture correction stick, etc., has two crossed sticks. The user leans against the vertical stick and hooks the horizontal stick with his arms backwards with his elbows, thereby opening the shoulders and beautifying the back, and correcting the standing posture.

[0003] For example, the posture corrector disclosed in the invention patent with the authorization announcement number CN114396419B includes a connector, a first stick and a second stick. The connector includes a first connection seat, a second connection seat and an axle pin. The first connection seat and the second connection seat are connected by the axle pin. The first stick is inserted into the first through hole of the first connection seat, and the second stick is inserted into the second through hole of the second connection seat. The axle pin radially passes through the first stick and the second stick in sequence. The first connection seat and the second connection seat are pulled apart and rotated relatively. The first connection seat and the second connection seat can be switched between two states. In the first state, the first stick and the second stick are parallel to each other; in the second state, the first stick and the second stick are staggered to form a cross.

[0004] In order to further correct the body shape of the neck, some body sticks add a headrest or neck support at the upper end of the vertical stick. For example, the utility model patent with authorization announcement number CN220736108U discloses a body correction training device, in which a neck and headrest is arranged on the second body stick. The user can use the neck and headrest to prevent the head from tilting during training and relieve neck pain.

[0005] However, the body stick with a headrest or a neck rest exposed two problems during use: first, when the first stick and the second stick are stored parallel to each other, the headrest or the neck rest is still horizontal relative to the two vertical sticks after being stored, which destroys the portability of the body stick for storage and carrying; second, different users have different heights, and some users like to lean their necks against the sticks, while other users like to lean their heads against the sticks.

[0074] like Figures 1 to 7 The figure shows a body stick 100 with a telescopic rotating pillow provided in this embodiment, which includes a first stick 101 and a second stick 102. The first stick 101 and the second stick 102 can be switched between a first state parallel to each other and a second state perpendicular to each other. The specific implementation method thereof can refer to the posture corrector disclosed in the invention patent with the authorization announcement number CN114396419B.

[0075] like Figure 2 and Figure 3 As shown, the body stick 100 with a gear-retractable rotating pillow also includes a pillow assembly 103 installed at the end of the first stick 101. The pillow assembly 103 includes a pillow 10, a rotating mechanism 20 and a gear-retractable mechanism 30. Among them, the rotating mechanism 20 is used to make the pillow 10 Figure 2The use position L1 shown and Figure 3 The gear telescopic mechanism 30 is used to adjust the height of the pillow 10 relative to the first stick 101 by rotating and switching between the storage positions L2 shown.

[0076] First, let's look at the rotating mechanism 20 in detail. Figure 4 and Figure 5 As shown, the rotating mechanism 20 includes a rotating disk 21 and at least one ball 22. The rotating disk 21 has a rotating surface 23, and at least two positioning pits 24 are recessed on the rotating surface 23, including a first positioning pit 24a and a second positioning pit 24b. The rotating surface 23 is also recessed with a ball track 25 that passes through the positioning pits 24.

[0077] The pillow 10 is rotatably connected to the turntable 21, and the ball 22 is held between the rotating surface 23 and the pillow 10. The pillow 10 rotates relative to the turntable 21, and the ball 22 rolls in the ball track 25. When the ball 22 enters the first positioning pit 24a, the pillow 10 is locked in the use position L1 perpendicular to the first stick 101. When the ball 22 enters the second positioning pit 24b, the pillow 10 is locked in the storage position L2 parallel to the first stick 101.

[0078] When the first stick 101 and the second stick 102 are in the Figure 1 and Figure 2 When the two sides are in the second state perpendicular to each other, the pillow 10 is rotated to the use position L1 perpendicular to the first stick 101, and the user can Figure 1 As shown in the figure, the body stick 100 with a gear-type telescopic rotating pillow is carried on the back, the back is against the first stick 101, the two arms are backward, the elbows are hooked on the second stick 102, and the back of the head or the back of the neck is against the pillow 10, so as to correct the body shape of the entire back, cervical spine, and head, and achieve the effect of opening the shoulders and beautifying the back.

[0079] When the first stick 101 and the second stick 102 are in the Figure 3 In the first parallel state shown, the pillow 10 is rotated to the storage position L2 parallel to the first stick 101, and then the pillow 10 together with the entire body stick 100 with a telescopic rotating pillow with gears are stored into a bundle, which is convenient to carry and saves storage space.

[0080] When the pillow 10 rotates relative to the turntable 21, the ball 22 rolls on the rotating surface 23 to reduce friction and make the rotation process smoother. The ball track 25 guides the rolling of the ball 22. The ball 22 enters the positioning pit 24 to lock the relative position of the pillow 10. The entire rotation and locking process is easy and quick.

[0081] like Figure 4 and Figure 5As shown, in the present embodiment, there are two balls 22, and they are centrally symmetrically arranged on the back side of the pillow 10. There are four positioning pits 24, including two centrally symmetrical first positioning pits 24a, and two centrally symmetrical second positioning pits 24b. The straight line where the two first positioning pits 24a are located is orthogonal to the straight line where the two second positioning pits 24b are located, so as to lock the pillow 10 in the mutually orthogonal use position L1 and storage position L2. The ball track 25 is an annular track that runs through the four positioning pits 24. The use of two centrally symmetrical balls 22 in conjunction with the four centrally symmetrical positioning pits 24 makes the force on both sides of the pillow 10 more balanced, the rotation is smoother, and the locking is more reliable.

[0082] like Figure 5 As shown, two ball retaining columns 11 are provided on the back side of the pillow 10, and a spring compartment 12 is provided in the ball retaining column 11, and a spring 13 is placed in the spring compartment 12. The ball 22 is retained between the rotating surface 23 and the ball retaining column 11, and the ball 22 is guided by the ball retaining column 11 to roll in the ball track 25 and enter and exit the positioning pit 24. The spring 13 elastically acts on the ball 22 to make the ball 22 enter and exit the positioning pit 24, that is, the spring 13 is almost always compressed and maintains the elastic pressure on the ball 22. When the ball 22 enters the positioning pit 24, the spring 13 slightly extends to press the ball 22 to prevent the ball 22 from easily leaving the positioning pit 24. When the pillow 10 is rotated, the spring 13 is slightly compressed to make the ball 22 leave the positioning pit 24 and enter the ball track 25.

[0083] like Figure 4 and Figure 5 As shown, a rotation hole 26 is provided at the center of the turntable 21, and a fixing hole 14 is provided on the back side of the headrest 10, through which a fixing bolt 15 passes and is fixedly connected to the fixing hole 14, and the fixing bolt 15 can rotate in the rotation hole 26, so that the headrest 10 and the turntable 21 can be rotatably connected. During assembly, the fixing bolt 15 can be fixedly connected to the fixing hole 14 by thread fastening, screw fastening, gluing, etc.

[0084] Let's look at the gear telescopic mechanism 30 in more detail. Figures 4 to 7 As shown, the gear telescopic mechanism 30 includes a telescopic tube 40 that can be telescoped relative to the end of the first stick 101, a gear locking bead 31 and an unlocking sleeve 50. A plurality of gear holes 41 are arranged on the side wall of the telescopic tube 40 along the telescopic direction, and the unlocking sleeve 50 is sleeved on the end of the first stick 101 to keep the gear locking bead 31 between the telescopic tube 40 and the first stick 101.

[0085] like Figure 4 and Figure 5As shown, the turntable 21 is fixed on the telescopic tube 40 to rotatably fix the pillow 10 on the telescopic tube 40. In the present embodiment, the turntable 21 is fixed to the top end of the telescopic tube 40. Of course, in other embodiments, the top end of the telescopic tube 40 may be further extended to fix other components, such as expanding a second pillow, etc. Therefore, the pillow 10 may also be fixed at a position below the top end of the telescopic tube 40.

[0086] like Figure 7 As shown, the unlocking sleeve 50 moves to the locking position L3 relative to the end of the first stick 101 to push the gear locking bead 31 into a gear hole 41. At this time, at least a part of the gear locking bead 31 enters the gear hole 41, and the other part remains on the first stick 101, so the telescopic tube 40 is locked at the extended length corresponding to the gear, and then the headrest 10 is locked at the height corresponding to the gear.

[0087] like Figure 6 As shown, the unlocking sleeve 50 moves to the unlocking position L4 relative to the end of the first stick 101, and the gear locking bead 31 leaves the gear hole 41. At this time, the telescopic tube 40 is unlocked and can be extended and retracted along the extension direction of the first stick 101, thereby adjusting the height of the pillow 10 relative to the first stick 101. The user can quickly and easily adjust the pillow 10 to a suitable height to adapt to the height and body characteristics of different users, and it is also convenient for the pillow 10 to switch between the headrest and neckrest functions.

[0088] like Figures 4 to 7 As shown, the gear telescopic mechanism 30 also includes an end sleeve 60 fixed to the end of the first stick 101. The side wall of the end sleeve 60 is provided with a locking bead holding hole 61, and a telescopic hole 62 is axially provided for the telescopic tube 40 to pass through, and the telescopic hole 62 is connected with the locking bead holding hole 61. The telescopic tube 40 passes through the telescopic hole 62 to telescope relative to the end of the first stick 101, and the unlocking sleeve 50 is sleeved on the outer periphery of the end sleeve 60, and the gear locking bead 31 is retained in the locking bead retaining hole 61, and then no matter the gear locking bead 31 is pushed into or out of the gear hole 41, or the telescopic tube 40 is telescoped along the extension direction of the first stick 101, the gear locking bead 31 is always retained in the locking bead retaining hole 61 and is not easy to fall off.

[0089] The end sleeve 60 provided in this embodiment is independent of the end of the first stick 101, which is convenient for assembly and disassembly. In other embodiments, the end sleeve 60 can be integrated with the end of the first stick 101, or the end sleeve 60 can be omitted, and the end of the first stick 101 is provided with a locking bead retaining hole to retain the gear locking bead 31.

[0090] In addition, the gear locking bead 31 is used as the gear locking piece. When the unlocking sleeve 50 moves and the telescopic tube 40 is extended and retracted, there is rolling friction between the gear locking bead 31 and the inner wall of the unlocking sleeve 50, the outer wall of the telescopic tube 40 and the end of the first stick 101 or the locking bead retaining hole 61 of the end sleeve 60. The friction force is small, and the operation is smoother when adjusting the gear.

[0091] like Figure 4 and Figure 5 Combination Figure 6 and Figure 7 As shown, the side wall of the telescopic tube 40 is provided with a first plane 42 along the telescopic direction, and the gear holes 41 are arranged on the first plane 42. The inner wall of the telescopic hole 62 is provided with a second plane 63 that matches the first plane 42, and the locking bead holding hole 61 is opened on the second plane 63. The first plane 42 and the second plane 63 cooperate to restrict the telescopic tube 40 in the circumferential direction to prevent the telescopic tube 40 from rotating circumferentially during the telescopic process, so that the moving track of the locking bead holding hole 61 on the side wall of the telescopic tube 40 coincides with the straight line where the gear hole 41 is located, so that the gear locking bead 31 can accurately enter the gear hole 41 to lock the telescopic tube 40 relative to the end sleeve 60 and the first stick 101.

[0092] like Figure 6 and Figure 7 As shown, a limiting protrusion 43 is provided at the bottom end of the first plane 42, and a limiting wall 64 is provided on the inner wall of the telescopic hole 62. The limiting protrusion 43 abuts against the limiting wall 64 to limit the maximum distance that the telescopic tube 40 extends out of the first stick 101, so as to avoid the telescopic tube 40 being pulled out of the first stick 101 as a whole when the telescopic tube 40 is telescopically adjusted.

[0093] like Figure 6 and Figure 7 As shown, the inner wall of the unlocking sleeve 50 includes a first inner wall 51 and a second inner wall 52. When the unlocking sleeve 50 is sleeved on the end of the first stick 101, that is, in this embodiment, it is sleeved on the outer periphery of the end sleeve 60 to be sleeved on the end of the first stick 101, the distance between the first inner wall 51 and the side wall of the telescopic tube 40 is smaller than the distance between the second inner wall 52 and the side wall of the telescopic tube 40.

[0094] like Figure 7 As shown, the unlocking sleeve 50 moves to the locking position L3 along the first direction V of the extension direction of the first stick 101. Figure 7 In the figure, the first inner wall 51 moves downward relative to the first stick 101 and the end sleeve 60, and contacts the gear locking bead 31 and pushes it into a gear hole 41 to achieve gear locking. Figure 6 As shown, the unlocking sleeve 50 moves to the unlocking position L4 in the opposite direction of the first direction V of the extension direction of the first stick 101. Figure 6In the middle, the first stick 101 and the end sleeve 60 move upward, and the second inner wall 52 is located outside the gear locking bead 31 and releases it, and the gear locking bead 31 can leave the gear hole 41 to unlock.

[0095] It should be noted that, in this embodiment, the inner wall of the unlocking sleeve 50 has a conical surface, the first inner wall 51 is the inner wall with a smaller diameter at the upper part of the conical surface, and the second inner wall 52 is the inner wall with a larger diameter at the lower part of the conical surface. In other embodiments, the first inner wall 51 and the second inner wall 52 with a radial depth difference can also be processed on the inner wall of the unlocking sleeve 50, and the first inner wall 51 and the second inner wall 52 with a certain elastic stress and a radial depth difference can be further used to push and release the gear locking bead 31.

[0096] Furthermore, if Figure 6 and Figure 7 As shown, a limiting edge 65 is convexly provided on the top of the end sleeve 60, a first limiting platform 66 is convexly provided on the peripheral side wall of the end sleeve 60, and a second limiting platform 53 is convexly provided on the inner peripheral wall of the unlocking sleeve 50. The top end of the unlocking sleeve 50 abuts against the limiting edge 65 to limit the limit position of the unlocking sleeve 50 moving in the opposite direction of the first direction V, and the first limiting platform 66 abuts against the second limiting platform 53 to limit the limit position of the unlocking sleeve 50 moving in the first direction V.

[0097] Dynamically, the unlocking sleeve 50 moves to the locking position L3 along the first direction V of the extension direction of the first stick 101, that is, moves downward relative to the first stick 101 and the end sleeve 60, when the first limiting platform 66 abuts against the second limiting platform 53, the first inner wall 51 pushes the gear locking bead 31 into the first gear hole 41; the unlocking sleeve 50 moves to the unlocking position L4 along the opposite direction of the first direction V of the extension direction of the first stick 101, that is, moves upward relative to the first stick 101 and the end sleeve 60, when the top of the unlocking sleeve 50 abuts against the limiting edge 65, the second inner wall 52 releases the gear locking bead 31. This not only facilitates the locking and unlocking operations, but also prevents the unlocking sleeve 50 from coming off the end sleeve 60 when moving.

[0098] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
