Technical Field
[0001] This application relates to the field of computer desks, and more particularly to a computer desk with an elbow rest. Background Technology
[0002] A computer desk is an essential piece of furniture for daily office work. It typically contains a mouse and keyboard for the user. When using the mouse, the user's forearm rests flat on the desk, while the upper arm is tilted at a certain angle. The force of gravity on the upper arm is vertically downwards, while the support force from the desk on the elbow is vertically upwards. To maintain this balance, the trapezius muscle and shoulder bones work together to provide an upward force (such as...). Figure 1 As shown in the image, the trapezius muscle is constantly under tension when using a mouse, which can easily lead to muscle strain, myofascitis, and other problems over time. Utility Model Content
[0003] To address the issue of trapezius muscle tension when using a mouse, this application provides a computer desk with an elbow rest.
[0004] The computer desk with an elbow rest provided in this application adopts the following technical solution:
[0005] A computer desk with an elbow rest, comprising:
[0006] The table body includes a tabletop;
[0007] An elbow rest, extending from the desktop toward the operator's body, is used to provide vertical upward support for the operator's elbow;
[0008] The lateral support mechanism includes a slider slidably disposed on the elbow rest and a lateral support rotatably disposed on the slider. The sliding trajectory of the slider is parallel to the width direction of the operator's body. The lateral support abuts against the side of the operator's elbow to provide horizontal support for the operator's elbow. The lateral support mechanism also includes a first locking component for locking the position of the slider and a second locking component for locking the lateral support.
[0009] This application provides horizontal support to the operator's elbow by having a lateral support member abut against the side of the elbow, thereby replacing the force exerted by the trapezius muscle on the upper arm and relieving tension in the trapezius muscle.
[0010] Furthermore, a slide rail is fixedly provided on the lower end face of the elbow support plate, and the sliding member is a slider that is slidably disposed on the slide rail.
[0011] The position of the slider on the elbow support plate can be adjusted by sliding the slider. When the lateral support is needed to provide lateral support for the operator's elbow, the slider is slid toward the operator's elbow and then locked in place by the first locking component. When the lateral support is not needed, the slider is slid away from the operator's elbow so as not to affect the operator's normal work on the table.
[0012] Furthermore, the slider includes an upper slide plate and a lower slide plate arranged opposite to each other, and also includes a connecting slide plate fixed to one side of the upper slide plate and the lower slide plate. The lower slide plate is adapted to slide along the slide rail, and the gap between the upper slide plate and the lower slide plate is used to accommodate the elbow support plate.
[0013] Furthermore, the slide rail includes an upper plate and a lower plate disposed opposite to each other, and also includes a connecting plate fixed to both ends of the upper plate and the lower plate, the gap between the upper plate and the lower plate being used to accommodate the lower slide plate.
[0014] Furthermore, the lower slide plate of the slider is provided with a downwardly protruding protrusion, and the lower plate of the slide rail is provided with a groove that is adapted to slide with the protrusion.
[0015] As the slider slides along the slide rail, the protrusion slides along the groove, thus guiding the slider's movement.
[0016] Furthermore, a first screw is fixedly connected to the lower end face of the slide plate, and an elongated hole for the first screw to slide in the lower plate of the slide rail. The elongated hole extends along the sliding direction of the slider, and the first locking assembly includes a first nut threadedly connected to the first screw.
[0017] When the slider slides along the slide rail, the first screw slides along the elongated hole, further guiding the slider's movement. When it is necessary to lock the slider's position, the first nut is tightened onto the first screw, causing the first nut to abut against the lower end face of the lower plate, thereby fixing the lower slide plate to the lower plate and locking the slider's position on the slide rail.
[0018] Furthermore, a vertical rotating shaft is fixedly connected to the slider, the lateral support is a vertical baffle, and a bushing is fixedly connected to the side of the baffle away from the operator's elbow, with the rotating shaft passing through the bushing.
[0019] The baffle can rotate around a pivot, enabling a rotatable connection between the baffle and the slider. By rotating the baffle, the tilt angle can be adjusted to better adapt to the operator's forearm posture when using the mouse.
[0020] Furthermore, a second screw is fixedly connected to the slider, and an arc-shaped plate is fixedly connected to the side of the baffle away from the operator's elbow. An arc-shaped hole is provided on the arc-shaped plate for the second screw to slide.
[0021] When the baffle rotates around the pivot, the second screw slides along the arc-shaped hole, which guides the rotation of the baffle.
[0022] Furthermore, the second locking component includes a second nut threadedly connected to the second screw.
[0023] When the baffle is rotated to the appropriate position, tighten the second nut onto the second screw so that the second nut abuts against the upper end face of the arc plate, thereby locking the position of the baffle.
[0024] Furthermore, a soft pad is fixed to the side of the baffle facing the elbow.
[0025] The soft padding on the baffle contacts the operator's elbow, which helps improve the operator's elbow comfort.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. This application is securely installed and easy to operate. The lateral support abuts against the side of the operator's elbow, providing horizontal support to the operator's elbow and replacing the force exerted by the trapezius muscle on the upper arm, thereby relieving the tension of the trapezius muscle.
[0028] 2. By sliding the slider, the position of the slider on the elbow support plate can be adjusted. When the lateral support is not needed, the slider can be moved away from the operator's elbow, so as not to affect the operator's normal work on the table.
[0029] 3. By rotating the baffle, the tilt angle of the baffle can be adjusted so that the baffle can better adapt to the posture of the operator's forearm when using the mouse;
[0030] 4. The soft padding on the baffle contacts the operator's elbow, which helps to improve the comfort of the operator's elbow. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.
[0038] This application discloses a computer desk with an elbow rest. (See also...) Figure 2 The computer desk with elbow rest includes a desk body, which includes a horizontal desktop 15 and multiple vertical desk legs supported on the bottom of the desktop 15.
[0039] Reference Figure 2 One edge of the desktop 15 extends towards the operator's body to form an elbow rest 16, which can be integrally molded with the desktop 15. The elbow rest 16 provides vertical upward support for the operator's elbow. Considering that most operators use their right hand to operate the mouse, the elbow rest 16 is usually located on the right side of the desktop 15.
[0040] Reference Figure 2 The elbow rest 16 is equipped with a lateral support mechanism, which includes a slider slidably mounted on the elbow rest 16 and a lateral support rotatably mounted on the slider. The slider is a slider 6, whose sliding trajectory is parallel to the width direction of the operator's body. The lateral support is a vertical baffle 1, which abuts against the side of the operator's elbow, applying a horizontal force toward the operator's body to the upper arm, replacing the force exerted by the trapezius muscle on the upper arm, thereby relieving tension in the trapezius muscle. The lateral support mechanism also includes a first locking component for locking the position of the slider 6 and a second locking component for locking the baffle 1.
[0041] Reference Figure 2 and Figure 3 A slide rail 7 is fixedly mounted on the lower end face of the elbow support plate 16, and the slider 6 is slidably mounted on the slide rail 7. For details, refer to... Figure 4 and Figure 5The slider 6 includes an upper slide plate 601 and a lower slide plate 602 arranged opposite to each other, and a connecting slide plate 603 fixed to one side of the upper slide plate 601 and the lower slide plate 602. The lower slide plate 602 is adapted to slide with the slide rail 7, and the gap between the upper slide plate 601 and the lower slide plate 602 can accommodate the elbow support plate 16. The upper slide plate 601, the lower slide plate 602 and the connecting slide plate 603 can be integrally formed into the slider 6, or they can be fixedly connected by welding or other methods.
[0042] Reference Figure 4 and Figure 5 The slide rail 7 includes an upper plate 701 and a lower plate 702 disposed opposite to each other, and a connecting plate 703 fixed to both ends of the upper plate 701 and the lower plate 702 along their length. The gap between the upper plate 701 and the lower plate 702 is used to accommodate the lower slide plate 602. To reduce the vertical displacement of the slider 6 on the slide rail 7, the distance between the upper plate 701 and the lower plate 702 is adapted to the thickness of the lower slide plate 602. The lower slide plate 602 of the slider 6 is provided with a downwardly protruding protrusion 604, and the lower plate 702 of the slide rail 7 is provided with a groove 704 that is adapted to slide with the protrusion 604.
[0043] To facilitate fixing the slide rail 7 to the elbow support plate 16, refer to... Figure 3 The upper plate 701 has mounting holes 12 at its four corners. Alternatively, the upper plate 701 can be fixed to the lower end face of the elbow support plate 16 by adhesive bonding, thereby fixing the slide rail 7 to the elbow support plate 16.
[0044] Before assembling the slider 6 and the slide rail 7, the upper plate 701, lower plate 702 and connecting plate 703 of the slide rail 7 are in a separate state, while the slider 6 is a whole. During assembly, first, the protrusion 604 of the lower slide plate 602 of the slider 6 is inserted into the groove 704 of the lower plate 702. Then, the two connecting plates 703 are welded to the two ends of the lower plate 702 respectively. Finally, the upper plate 701 is welded to the connecting plate 703, thus completing the assembly of the slide rail 7 and the slider 6.
[0045] When the assembly of slide rail 7 and slider 6 is fixed to elbow support plate 16, refer to Figure 5 In (a), the lower end face of the upper slide plate 601 abuts against the upper end face of the elbow support plate 16, and the inner side of the connecting slide plate 603 abuts against the side of the elbow support plate 16. In another feasible embodiment, in order to facilitate the sliding of the slider 6, there may be a slight gap between the lower end face of the upper slide plate 601 and the upper end face of the elbow support plate 16.
[0046] As the slider 6 slides along the slide rail 7, the protrusion 604 slides along the groove 704, thus guiding the sliding of the slider 6. The position of the baffle 1 on the elbow support plate 16 can be adjusted by the sliding of the slider 6 to accommodate arms of different lengths. When the baffle 1 is needed to provide lateral support to the operator's elbow, the slider 6 is slid towards the operator's elbow, and then the position of the slider 6 is locked by the first locking component; when the baffle 1 is not needed, the slider 6 is slid away from the operator's elbow, without affecting the operator's normal work on the tabletop 15.
[0047] Reference Figure 4 and Figure 5 A vertical first screw 14 is fixed to the middle of the lower end face of the slide plate 602. An elongated hole 11 is opened in the middle of the lower plate 702 of the slide rail 7 for the first screw 14 to pass through and slide. The elongated hole 11 extends along the sliding direction of the slider 6. When the slider 6 slides along the slide rail 7, the first screw 14 slides along the elongated hole 11, further guiding the sliding of the slider 6.
[0048] To lock the position of slider 6, refer to Figure 4 and Figure 5 The first locking component includes a first nut 13 threadedly connected to a first screw 14. When it is necessary to lock the position of the slider 6, the first nut 13 is tightened to the first screw 14, so that the first nut 13 abuts against the lower end face of the lower plate 702, thereby fixing the lower slide plate 602 to the lower plate 702 and locking the position of the slider 6 on the slide rail 7.
[0049] To adjust the rotation angle of baffle 1, refer to Figure 3 and Figure 4 A vertical rotating shaft 8 is fixedly connected to the upper slide plate 601 of the slider 6. A bushing 5 is fixedly connected to the side of the baffle 1 away from the operator's elbow. The rotating shaft 8 and the upper slide plate 601, as well as the bushing 5 and the baffle 1, can be connected by welding. The rotating shaft 8 passes through the bushing 5, thereby rotatably mounting the baffle 1 on the slider 6. Furthermore, an annular protrusion can be fixedly provided at the upper end of the rotating shaft 8. The size of the annular protrusion is larger than the inner diameter of the bushing 5, thereby preventing the bushing 5 from falling off the rotating shaft 8.
[0050] The baffle 1 can rotate around the pivot 8. By rotating the baffle 1, the tilt angle of the baffle 1 can be adjusted so that the baffle 1 can better adapt to the posture of the operator's forearm when using the mouse. When operating the mouse, the forearm needs to swing left and right frequently. The appropriately tilted baffle 1 can make room for the swing of the forearm. When moving the mouse back and forth, the elbow can slide along the baffle 1 so that the baffle 1 always supports the elbow.
[0051] Furthermore, referring to Figure 3 and Figure 4The upper slide plate 601 of the slider 6 is also fixedly connected to a second screw 9. An arc-shaped plate 3 is fixedly connected to the side of the baffle 1 away from the operator's elbow. The arc-shaped plate 3 has an arc-shaped hole 10 for the second screw 9 to slide through. The second screw 9 and the upper slide plate 601, as well as the arc-shaped plate 3 and the baffle 1, can be connected by welding. When the baffle 1 rotates around the pivot 8, the second screw 9 slides along the arc-shaped hole 10, guiding the rotation of the baffle 1.
[0052] To fix baffle 1, refer to Figure 3 and Figure 4 The second locking assembly includes a second nut 4 threadedly connected to the second screw 9. When the baffle 1 is rotated to the appropriate position, the second nut 4 is tightened to the second screw 9, so that the second nut 4 abuts against the upper end face of the arc-shaped plate 3, thereby locking the position of the baffle 1.
[0053] Components such as slider 6, slide rail 7, and baffle 1 can all be made of metal, such as stainless steel. To improve the operator's elbow comfort when contacting baffle 1, refer to... Figure 2 A soft pad 2 is fixed to the side of the baffle 1 facing the operator's elbow. The soft pad 2 can be made of rubber, silicone, etc.
[0054] The implementation principle of a computer desk with an elbow rest according to this application embodiment is as follows: When operating the mouse, the elbow is placed on the elbow rest plate 16, which provides upward support to the elbow. At the same time, the side of the elbow abuts against the baffle 1, which applies a horizontal force towards the operator's body to the upper arm, replacing the force of the trapezius muscle, thereby allowing the trapezius muscle to fully relax. Loosening the first nut 13 and sliding the slider 6 can adjust the position of the baffle 1 to accommodate arms of different lengths. Loosening the second nut 4 can adjust the tilt angle of the baffle 1, making it better suited to the posture of the operator's forearm when using the mouse. When operating the mouse, the forearm needs to swing left and right frequently. The appropriately tilted baffle 1 can make room for the forearm to swing. When moving the mouse back and forth, the elbow can slide along the baffle 1, so that the baffle 1 always supports the elbow. When not using the baffle 1, the slider 6 can be slid to move the baffle 1 to the edge of the desktop 15 without affecting the operator's normal work on the desktop 15.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
