Description

Technical Field

[0001] The utility model relates to photographing equipment, in particular to a hand support device and a handheld stabilizer having the same. Background Art

[0002] As handheld stabilizers have more and more functions and accessories, they are becoming heavier. Photographers using handheld stabilizers often adjust their grip to obtain different camera positions and effects. In this case, the photographer's arms and wrists are prone to fatigue, resulting in a poor user experience. Therefore, the known prior art provides a hand rest for the photographer to support the wrist and relieve fatigue when holding a handheld stabilizer. However, such hand rests have a simple structure and cannot adjust the angle according to the photographer's hand grip, resulting in poor practicality. Alternatively, such hand rests use a worm gear or a stepped adjustment structure without a self-locking function, which has problems such as large device size, poor adjustment flexibility, high component cost, and poor stability.

[0003] Therefore, the industry urgently needs to improve the angle adjustment structure of the hand support device and design an adjustable angle hand support device with simple and reliable structure, small space occupation, low manufacturing cost and user-friendly. Utility Model Content

[0004] The utility model aims to provide a hand support device which can at least solve some of the above technical problems.

[0005] The utility model also aims to provide a handheld stabilizer using the improved hand support device.

[0006] According to one aspect of the present invention, a hand rest device is provided, comprising a hand rest, a connecting seat, a rotating shaft, a transmission member, a screw, and a driving member. The hand rest comprises a support portion and a connecting portion, wherein the connecting portion is movably connected to the connecting seat via the rotating shaft, thereby enabling the hand rest to rotate within a preset range about the axis of the rotating shaft relative to the connecting seat. The driving member is connected to the screw and can drive the screw to rotate. The connecting portion is further provided with a groove for accommodating the transmission member, wherein the groove wall of the groove prevents the transmission member from rotating. The transmission member is threadedly connected to the screw, and when the transmission member moves along the axis of the screw, it abuts against the groove to drive the hand rest to rotate about the axis of the rotating shaft. Thus, the hand rest device, through the above structure, in particular, uses a threaded transmission member having an external thread matching the screw as a bridge to form a movable connection between the screw and the hand rest, respectively, to transmit and convert the self-rotation of the screw into a rotational adjustment of the hand rest angle within a certain range. Due to the threaded connection between the screw and the transmission member, the adjustable rotation angle of the hand rest is more precise and self-locking after adjustment, resulting in a simple and stable structure.

[0007] In some embodiments, the connecting base includes a housing chamber, in which the connecting portion, the rotating shaft, the transmission member, and the threaded section of the screw are all housed. The rotating shaft extends through the connecting portion and is connected to the wall of the housing chamber. The driving member is at least partially disposed outside the housing chamber. The housing chamber has an opening at the intersection of the connecting portion and the supporting portion, the size of which matches the range of rotation of the hand rest. The provision of the housing chamber prevents dust and dirt, making the device more compact and reliable, and the external driving member facilitates assembly and operation.

[0008] In some embodiments, the screw is disposed through the wall of the accommodating cavity and is spatially orthogonal to the rotating shaft, and one end of the screw extending through the cavity wall is fixedly connected to the driving member. This allows for manual screwing, simple assembly, low cost, and flexible and controllable adjustment of the hand rest angle.

[0009] In some embodiments, the transmission member is a hollow, internally threaded, cross-shaped transmission shaft or trunnion coaxially sleeved with the screw. Using a simple cross-shaped transmission shaft to transmit motion from the screw to the hand rest reduces the volume occupied by the structure, provides a stable and reliable structure, and reduces manufacturing costs.

[0010] In some embodiments, an anti-slip member is fixedly connected to one end of the screw away from the driving member, and the transmission member is located between the anti-slip member and the driving member to prevent the transmission member from falling off the screw. The provision of the anti-slip member further increases the stability of the hand support device.

[0011] In some embodiments, a guide groove is provided on the portion of the connecting portion facing the screw, the groove is located in the middle of the guide groove and communicates with the guide groove, and the screw is at least partially located within the guide groove. This prevents the screw from interfering with the movement of the connecting portion, makes the structure more compact, saves space, and reduces weight.

[0012] In some embodiments, the support portion is provided with a support surface, which is configured as an upwardly convex arc, and the surface of the support surface is provided with shock-absorbing material, thereby better conforming to the posture of the wrist and improving user comfort, effectively reducing user fatigue.

[0013] In some embodiments, the connection base includes an upper surface, a lower surface, and two opposite side surfaces. The connection base also includes a connecting bolt extending from the upper surface for connecting to a handheld stabilizer, a screw hole located on the lower surface for connecting to a tripod or other accessories, and an expansion port located on one of the side surfaces for connecting to auxiliary accessories. The hand rest is mounted on the other side surface. This fully utilizes all surfaces of the device, thereby increasing the practicality and scalability of the device, and preventing interference between functional components.

[0014] According to another aspect of the present invention, a handheld stabilizer is provided, comprising a handheld portion and the above-mentioned hand support device, wherein the connecting base of the hand support device is fixedly connected to the lower end of the handheld portion, thereby improving the experience of holding the handheld stabilizer and enriching the functions of the handheld stabilizer with a simple, reliable and low-cost structure.

[0015] In some embodiments, the palm rest can be adjusted in an angle range of -30 degrees to +30 degrees. When the support portion (111) rotates to the highest point, it is closest to the hand-held portion. When the support portion rotates to the lowest point, it is farthest from the hand-held portion. The adjustment range is appropriate and conforms to the range of motion of the average human wrist. It neither wastes space nor fully covers the adjustment range required for normal use.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The hand support angle can be adjusted by rotating the screw, with high adjustment accuracy and self-locking function, so that users can flexibly and conveniently adjust the hand support angle according to the wrist posture to greatly reduce wrist fatigue; and the utility model realizes the transmission of the hand support angle adjustment action through the simple cooperation of the screw, the rotating shaft and the transmission part. The structure is simple and compact, the stability is high, the manufacturing and assembly costs are low, and the scalability is strong. The connecting seat can also expand the attachable accessories according to the needs. The hand support device can adjust the drive mode by selecting manual or automatic drive parts. It is easy to modify and has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is described in detail below with reference to specific embodiments.

[0037] Example 1

[0038] like Figures 1 to 4 As shown, a hand rest device includes a hand rest 11, a connecting seat 12, a rotating shaft 13, a transmission member 14, a screw 15, and a driving member 16. The hand rest includes a supporting portion 111 and a connecting portion 112. The connecting portion 112 is movably connected to the connecting seat 12 through the rotating shaft 13, so that the hand rest can rotate around the axis of the rotating shaft 13 relative to the connecting seat 12 within a preset range. The axis of the rotating shaft 13 is the rotation axis for adjusting the angle of the hand rest. The transmission member 14 is movably connected to the screw 15 through a thread. The driving member 16 is connected to the screw 15 and can drive the screw to rotate. The connecting portion 112 is also provided with a groove 1121 for accommodating the transmission member. The groove wall of the groove 1121 prevents the transmission member 14 from rotating and abuts against the transmission member 14 in the movable direction.

[0039] Specifically, the lower part of the transmission member 14 can just be accommodated in the groove 1121 opened on the upper surface of the hand support connecting part 112, and there is almost no gap between the two, or only a very small gap exists, thereby limiting the movement or rotation of the transmission member 14 relative to the groove 1121, and the screw 15 and the transmission member 14 have matching threads. When the screw 15 rotates in one direction (such as clockwise), the distance between the end of the screw 15 close to the driving member and the transmission member 14 is shortened. When the screw 15 rotates in another direction (such as counterclockwise), the distance between the end of the screw 15 close to the driving member and the transmission member 14 increases, which is equivalent to causing the transmission member 14 to move forward or backward along the axis of the screw 15 by rotating the screw 15 in different directions, and stick to the groove wall of the groove in its moving direction, abutting against the groove 1121, and then pushing the hand support 11 to rotate around the axis of the rotating shaft 13. The screw 15 is driven by the driving member 16 to rotate, so the driving member 16 can be located at one end of the screw 15 and connected to the screw 15 in a fixed or integrally formed manner. It can be a component that requires manual operation or an automated component such as a motor.

[0040] Preferably, the connecting seat 12 includes a accommodating cavity 121, which has the functions of accommodating, limiting and supporting parts, preventing dust and being beautiful, and making the device stable and reliable. The connecting portion 112 of the hand rest and the rotating shaft 13, the transmission member 14, and the threaded section of the screw 15 are all accommodated in the accommodating cavity 121. The entire accommodating cavity 121 is a semi-enclosed structure, including a cavity wall 1211 for enclosing and an opening 122 communicating with the outside world, so that the supporting portion 111 of the hand rest connected to the connecting portion 112 can extend out of the accommodating cavity 121 and be rotated and adjusted within the size of the unenclosed opening 122. The two ends of the rotating shaft 13 are respectively connected to the cavity walls 1211 on the opposite sides of the accommodating cavity 121, so that the cavity walls 1211 of the accommodating cavity 121 support the rotating shaft 13 and the hand rest 11 connected to the rotating shaft 13.

[0041] Furthermore, the rotating shaft 13 can sequentially pass through the cavity wall 1211 on one side of the accommodating cavity 121, the connecting portion 112 of the hand rest, and the cavity wall 1211 on the other side of the accommodating cavity 121. The two ends of the rotating shaft 13 are fastened to the cavity wall 1211 supporting it by interference fit, glue, or threads. When the angle of the hand rest 11 is adjusted, the rotating shaft 13 and the hand rest 11 rotate relative to each other. Of course, the rotating shaft 13 can also be fixed to the hand rest 11, and the connecting portion 112 extends two shaft ends in opposite directions in the direction of the rotation axis. The two shaft ends are respectively inserted into the support holes 1212 provided on the two opposite cavity walls 1211, thereby being rotatably connected relative to the connecting seat 12. The rotating shaft 13 can be specifically connected to the connecting seat through a sleeve or a bearing to facilitate smooth rotation of the shaft end, or a gasket or spring can be added in the support hole to increase the stability and damping force of the shaft end.

[0042] Preferably, when the hand support device 1 is designed for simple and reliable manual adjustment, the driver 16 is at least partially disposed outside the accommodating cavity 121. For example, the screw rod 15 and the driver 16 are integrally formed as a bolt, and the driver 16 is the head of the bolt disposed outside the accommodating cavity. Alternatively, the driver 16 is a nut, wrench, or handle fixed to the screw rod 15, to facilitate manual adjustment by the user. Of course, the hand support device 1 can also be electrically adjustable, with the driver 16 correspondingly selecting a suitable motor and switch. In this way, the motor portion can be disposed inside the hand support device, such as inside the accommodating cavity, while the driver switch can be disposed outside the hand support device for user operation. After activation, the motor drives the screw rod to rotate.

[0043] Furthermore, if Figures 1 to 5 As shown, when the driving member 16 is a hand-tightening handle, for ease of assembly, a through hole 1214 is provided on the cavity wall 1211 between the two opposing cavity walls 1211 of the aforementioned accommodating cavity 121. The screw 15 passes through the through hole 1214 from the accommodating cavity 121 and is rotatably connected to the accommodating cavity 121, so that the middle threaded section of the screw 15 is located within the accommodating cavity. The end of the screw 15 that passes through the through hole 1214 is fixedly connected to the hand-tightening handle. Rotating the hand-tightening handle can drive the screw 15 to rotate, wherein the screw 15 is arranged orthogonally to the rotating shaft 13. To prevent the hand-tightening handle and the screw 15 from loosening, the two can be connected using adhesive or riveting. To ensure smooth rotation of the screw 15 relative to the accommodating cavity 121, the screw 15 can be rotatably connected to the inner side of the through hole 1214 via a bearing or nylon sleeve.

[0044] Of course, the screw 15 does not necessarily need to be perpendicular to the shaft 13. It is sufficient as long as the movement of the transmission member 14 within the groove 1121 can drive the support portion 111 to rotate relative to the shaft 13. For example, the screw 15 can be parallel to the shaft 13 and the movement direction of the transmission member 14, while the groove 1121 can be configured as a helical groove. However, this approach would require the screw and shaft to be supported on the same surface, which could result in a large space requirement and complicated assembly.

[0045] Preferably, the end of the screw 15 away from the driving member 16 is fixedly connected to an anti-slip member 17, and the transmission member 14 is located between the anti-slip member 17 and the driving member 16. The anti-slip member 17 is used to prevent the transmission member 14 from escaping from the screw 15 from the end away from the driving member.

[0046] Furthermore, the anti-slip member 17 is an anti-slip nut screwed onto the end of the threaded segment of the screw rod 15. The anti-slip nut and the accommodating cavity wall 1211 supporting the screw rod 15 together constitute two end limits on the moving path of the transmission member 14. The screw rod 15 located between the two end limits is a threaded segment, so as to ensure that the transmission member 14 will not be separated from the threaded connection of the screw rod 15 during any movement along this path. The specific form of the anti-slip member 17 is not limited, and it can also be a boss integrated with the screw rod 15. As long as it is located at the end of the screw rod 15 that needs to be limited, and the distance between the edge of the boss and its rotation center is greater than the inner radius of the hollow shaft of the transmission member 14, the boss abuts against the transmission member 14 that has moved there, thereby preventing the transmission member 14 from continuing to move in the extension direction of the end.

[0047] Of course, a further limiting structure can be provided within the restricted range of the opening 122 to further reduce the rotatable angle of the hand rest 11. By providing a limit on the rotation angle and appropriately designing the length of the threaded section of the screw 15 to match the transmission member 14, the anti-slip member 17 or other limiting means for the movement path of the transmission member 14 can be eliminated, thereby further optimizing the structure, reducing parts, and simplifying assembly.

[0048] Preferably, the portion of the connecting portion 112 facing the screw 15 is provided with a guide groove 1122. The groove 1121 is located in the middle of the guide groove 1122 and communicates with the guide groove 1122. The screw 15 is at least partially located within the guide groove 1122. The guide groove serves as a guide to prevent the screw from wobbling. It also makes the device more compact and avoids wasted space. Furthermore, the guide groove 1122 can also leave space for an anti-slip component.

[0049] Furthermore, a guiding structure is also provided on the cavity wall 1211 relative to the guide groove 1122, such as the reinforcing ribs 1213 arranged parallel to both sides of the screw 15. The reinforcing ribs 1213 not only serve to reinforce the cavity wall 1211, but also assist in positioning the screw 15 and the transmission part 14 during assembly.

[0050] Preferably, if Figure 6 As shown, the transmission member 14, which is threadedly connected to the screw 15, is a hollow, cross-shaped transmission shaft or trunnion with internal threads, or other components with internally threaded hollow shafts 141, and has protrusions 142 perpendicular to the hollow shaft. The protrusions 142 are located within grooves 1121. When the hand rest is adjusted, the protrusions abut the groove walls. As a result, the screw 15 can be screwed into the transmission member 14 from one end along the internal threads of the hollow shaft portion and unscrewed from the other end of the transmission member 14, forming a coaxial sleeve relationship between the transmission member 14 and the screw 15. The hollow shaft portion of the transmission member 14 is used to convert the rotational motion of the screw 15 into linear movement of the transmission member 14.

[0051] Of course, the transmission part 14 does not necessarily have to be an internal threaded part. As long as it is at least partially threadedly connected to the screw 15 and at least partially abuts the groove 1121 on the hand rest, it can transmit force between the screw and the hand rest and convert the rotation of the screw 15 into rotation of the hand rest 11.

[0052] Preferably, if Figure 7 As shown, the outer surface of the support part 111 of the palm rest 11 for supporting the user's wrist includes a support surface 1111, which is constructed into an upwardly convex arc. The surface of the support surface 1111 is provided with a shock-absorbing material, such as a soft pad made of sponge or silicone, so that the user's wrist can experience more comfort when contacting the support surface.

[0053] Preferably, if Figure 8 As shown, the connecting base 12 includes an upper surface 123, a lower surface 124, two side surfaces 125 opposite to each other, a connecting bolt 126, an expansion interface 127, and a screw hole. Among them, the connecting bolt 126 passes through the upper surface 123 and is used to connect the handheld stabilizer; the screw hole is provided on the lower surface 124 and is used to connect a tripod or other accessories; and the expansion interface 127 and the hand rest 11 for connecting auxiliary accessories are respectively provided on the two side surfaces 125. Specifically, the expansion interface 127 can be used to connect an auxiliary handle or an expansion bracket, or to install a remote control, etc. It can be an interface with an electrical connection to serve both the function of power supply and signal transmission. In other embodiments, other surfaces of the connecting base 12 can also be provided with a variety of connection structures or expansion interfaces, which are not limited here.

[0054] Furthermore, the palm rest 11 also has a bottom surface 1112, which is set as an anti-slip surface, for example, by attaching anti-slip material or making granular or striped patterns on the surface. When the bottom surface 1112 is flush with the lower surface 124 of the connecting seat, it can be placed on a flat surface, and the anti-slip surface increases the safety of the flat palm rest device.

[0055] Example 2

[0056] This embodiment provides a handheld stabilizer, including the hand support device mentioned in the first embodiment, such as Figure 9 As shown, the connection base 12 of the hand rest device 1 mentioned in the first embodiment is fixedly connected to the lower end of the handheld portion 21 of the handheld stabilizer 2. When using the handheld stabilizer, the user can rest their wrist on the hand rest device to reduce the stress on the wrist, increase the comfort of using the handheld stabilizer, and expand its usage modes and functions.

[0057] Typically, the bottom of the handheld portion has a standard quarter-thread thread, which facilitates connection to tripods, monopods, and other supports with matching bolts. Therefore, the simplest way to connect the hand-held stabilizer 1 in Example 1 to the handheld stabilizer is to connect the connecting bolts 126 on the connecting base to the standard threaded thread on the bottom of the handheld portion 21. To ensure a secure connection to the handheld stabilizer, a rotation stop can also be provided on the upper surface of the connecting base 12 to prevent the handheld stabilizer 2 from accidentally loosening after being tightened to the connecting bolts 126.

[0058] Of course, the fixed connection method between the connecting base 12 and the lower end of the hand-held part 21 is not limited to this, and also includes providing mutually matching quick-release and quick-installation and locking structures, such as dovetail grooves and dovetail slides, on the upper surface 124 of the connecting base and the lower end of the hand-held part, or providing a clamping structure on the connecting base 12 that can clamp the lower end of the hand-held part, such as a clamping arm or a clamping ring.

[0059] The aforementioned methods can all achieve a detachable connection between the hand-supporting device 1 and the hand-held stabilizer 2 , and the two can also be connected in an integrally formed, welded or other non-detachable fixed manner.

[0060] In addition, the adjustable angle range of the hand rest 11 is preferably -30 degrees to +30 degrees. When the support portion 111 rotates to the highest point, it is closest to the hand-held portion 21. When the support portion 111 rotates to the lowest point, it is farthest from the hand-held portion 21. It can be understood that the position range of the support portion 111 from the center to the highest point is more suitable for the posture of holding the hand-held portion 21 and lifting the hand-held stabilizer 2 to shoot in the middle / high position, and the range of the support portion 111 from the center to the lowest point is more suitable for the posture of holding the hand-held portion 21 and lifting the hand-held stabilizer 2 to shoot in the middle / low position.

[0061] like Figure 10 As shown, the handheld portion 21 of the handheld stabilizer 2 is vertically mounted on the upper surface 123 of the connecting base, and the upper and lower surfaces of the connecting base are parallel. When the bottom surface 1112 of the support portion is flush with the lower surface 124 of the connecting base, the hand rest 11 intersects the connecting base 12 at 0 degrees. The hand rest 11 can adjust the angle within the range of ±30 degrees of intersection with the connecting base 12. This range is a comfortable range for human wrist movement, and meets the user's wrist support requirements when changing postures when holding the handheld stabilizer to switch between high and low positions for shooting.

[0062] In summary, the utility model drives the screw 15 to rotate through the driving member 16, and the screw 15 can adjust the position of the transmission member 14 when it rotates. In the process of the transmission member 14 moving back and forth along the screw 15, it cooperates to push the palm rest 11 to adjust the angle. The adjustment is accurate and can be self-locking, so that the user can flexibly adjust the palm rest angle according to the wrist posture to greatly reduce wrist fatigue. The utility model realizes the transmission of the palm rest angle adjustment action through the simple cooperation of the screw, the rotating shaft and the transmission member. The structure is simple and compact, the stability is high, the manufacturing and assembly costs are low, and the scalability is strong. The connecting seat can also expand the attachable accessories according to the needs. The palm rest device can adjust the drive mode by selecting manual or automatic drive members. It is easy to modify and has strong adaptability.

[0063] The handheld stabilizer provided by the utility model is more labor-saving with the help of the hand support device, is suitable for shooting in various camera positions, increases user comfort, and expands the functions of the handheld stabilizer while occupying as little space as possible.

[0064] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
