Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to an arm support device. Background Technology

[0002] In modern life, the multi-functionality of chairs is becoming increasingly prominent. Taking the armrests of office chairs as an example, the position of existing chair armrests can generally be adjusted to meet people's usage needs. However, the most important function of existing armrests is to support the human arm. On this basis, and considering cost factors, the armrest surface is uniformly long and thin. This shape of armrest can effectively achieve the function of supporting the human arm at a lower cost, so manufacturers have always adhered to this design.

[0003] In some situations, such as small meetings in an office that are not held at a conference table, people who want to take notes have to raise their arms and write on their notebooks with their hands suspended in the air. Although there are armrests to support their arms, it is not convenient to write and is not as comfortable as placing the notebook on the table. Moreover, maintaining this posture for a long time can be very tiring.

[0004] Take sofa armrests as another example. Sofa armrests are generally larger and usually consist of block-shaped boxes, with a long and narrow surface. However, some sofas have hidden flip-out trays within the armrests. Users can open the armrest, rotate the tray upwards, and then rotate it horizontally. They can then place their belongings on the tray, as seen in some movie theater sofas. Of course, some trays are designed to fold to accommodate different storage spaces.

[0005] Office chairs, due to their portability and simplicity, do not have enough space in their armrests to accommodate a small table, thus they cannot be used to place items. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model provides an arm support device, including an armrest and a support base. A flip-up support is provided on the armrest, which can rotate between vertical and horizontal positions. When the flip-up support is vertical, the device is in its normal state, with the flip-up support hanging down beside the armrest and support base. When the user uses the device as an armrest to support their arm, they will not be affected by the flip-up support, nor will the device protrude in the left or right direction and obstruct passersby. When the flip-up support is horizontal, the device is in a placement state, with the flip-up support lying flat beside the armrest, forming a larger placement area, i.e., a small table, for the user to place items. Moreover, in the placement state, the upper surface of the flip-up support is flush with the upper surface of the armrest, which is more conducive to placing items.

[0007] The technical solution of this utility model is implemented as follows:

[0008] An arm support device includes an armrest and a support base. The support base is configured as a main support, and the armrest is mounted on the support base. A flip support is rotatably disposed on the armrest. The arm support device has a normal state and a placement state. In the normal state, the flip support hangs vertically beside the armrest and the support base. In the placement state, the flip support is laid horizontally beside the armrest, and the upper surface of the flip support is flush with the upper surface of the armrest.

[0009] In this design, a flip-up support is installed on the handrail. The flip-up support can rotate and switch between vertical and horizontal positions. When the flip-up support is vertical, the device is in its normal state, with the flip-up support hanging down beside the handrail and support base. When the user uses the device as a handrail to support their arm, they will not be affected by the flip-up support, nor will the device protrude in the left and right directions and obstruct passersby. When the flip-up support is horizontal, the device is in its storage state. The flip-up support lies flat beside the handrail, forming a larger storage area, i.e., a small table, for the user to place items. Moreover, in the storage state, the upper surface of the flip-up support is flush with the upper surface of the handrail, which is more conducive to placing items.

[0010] Preferably, the armrest also includes a shaft protruding from the armrest in the front-to-back direction, and the tilting support is rotatably connected to the armrest via the shaft. A locking mechanism is provided between the shaft and the armrest or between the shaft and the tilting support, and the locking mechanism is configured to keep the tilting support horizontal when an item is placed on it. The shaft can be a single shaft passing through the armrest, or two shafts located at the front and rear ends of the armrest, respectively. The shaft can be fixed to the armrest and rotate with the tilting support, or it can be fixed to the tilting support and rotate with the armrest. The presence of the locking mechanism ensures that the tilting support remains horizontal, thus maintaining stability in the placed state and allowing items to be smoothly placed on the small table formed by the armrest and the tilting support.

[0011] Preferably, the shaft is fixed to the handrail component, and the locking mechanism is a Japanese snap-fit ​​hinge, located between the shaft and the tilting support. This method of positioning the locking mechanism between the shaft and the tilting support is more convenient and easier to implement than integrating it into the handrail component.

[0012] Preferably, in the left-right direction, the shaft is positioned near the end of the handrail and on the upper part of the handrail; the projection of the shaft in the front-back direction is on the handrail. Because the device already has an additional flip support, it is slightly more abrupt than a conventional handrail. This design ensures that the shaft does not protrude from the handrail in the left-right direction, minimizing the abruptness of the arm support device.

[0013] Preferably, the flip support includes a connecting part and a main body. One end of the connecting part is rotatably connected to the shaft, and the other end is connected to the main body. In the placed state, the main body is located next to the handrail. In the normal state, the connecting part protrudes upward from the main body.

[0014] Preferably, there is a notch between the main body and the connecting part, which is configured to avoid the handrail when the tilting support rotates. The tilting support needs to rotate between horizontal and vertical positions, and it is easy to interfere with the handrail when rotating. To avoid collision and interference, a notch is provided between the main body and the connecting part.

[0015] Preferably, the distance from the end edge of the armrest near the shaft to the shaft is no greater than the length of the connecting part protruding from the main body. Furthermore, while maintaining clearance, it also ensures that there is only a small gap or no gap between the flip support and the armrest when the item is placed on it.

[0016] Preferably, in the normal state, the flip support is located below the upper surface of the armrest. In the normal state, the flip support does not affect the normal use of the armrest, and the arm will not be blocked or bumped when resting on the armrest.

[0017] Preferably, the length of the flip support in the front-to-back direction is greater than the length of the handrail. The longer length of the flip support allows the connecting part to be outside the handrail, that is, in the front-to-back direction, the connecting part is located in front of and behind the handrail, which is also to avoid the handrail as much as possible and not interfere with the normal use of the handrail; of course, the connecting part of the flip support can also be directly rotated to the handrail, but the handrail needs to be slotted.

[0018] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0019] In this design, a flip-up support is installed on the handrail. The flip-up support can rotate and switch between vertical and horizontal positions. When the flip-up support is vertical, the device is in its normal state, with the flip-up support hanging down beside the handrail and support base. When the user uses the device as a handrail to support their arm, they will not be affected by the flip-up support, nor will the device protrude in the left and right directions and obstruct passersby. When the flip-up support is horizontal, the device is in its storage state. The flip-up support lies flat beside the handrail, forming a larger storage area, i.e., a small table, for the user to place items. Moreover, in the storage state, the upper surface of the flip-up support is flush with the upper surface of the handrail, which is more conducive to placing items.

[0020] Because an additional flip support is installed in this device, it is relatively abrupt compared to a conventional handrail. This solution aims to minimize the abruptness by adjusting the position of the shaft and the structure of the flip support. Furthermore, the position of the shaft and the structure of the flip support work together to ensure that the flip support does not interfere with the handrail when flipped, while also minimizing the gap between the flip support and the handrail when items are placed on it.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] The specific implementation of this utility model is as follows:

[0031] like Figure 5 As shown, this utility model provides an arm support device, including a handrail 1 and a support base 2. The support base 2 is configured as the main support, and the handrail 1 is installed on the support base 2. A flip support 3 is rotatably arranged on the handrail 1. The arm support device has a normal state and a placement state. In the normal state, the flip support 3 hangs vertically next to the handrail 1 and the support base 2. In the placement state, the flip support 3 is laid horizontally next to the handrail 1, and the upper surface of the flip support 3 is flush with the upper surface of the handrail 1.

[0032] In this design, a flip support 3 is installed on the armrest 1. The flip support 3 can rotate and switch between vertical and horizontal. When the flip support 3 is vertical, the device is in its normal state, with the flip support 3 hanging down beside the armrest 1 and the support base 2. When the user uses the device as an armrest to support their arm, they will not be affected by the flip support 3, nor will the device protrude in the left and right directions and obstruct passersby. When the flip support 3 is horizontal, the device is in a storage state, with the flip support 3 lying flat beside the armrest 1, forming a larger storage area, i.e., a small table, for the user to place items. Moreover, in the storage state, the upper surface of the flip support 3 is flush with the upper surface of the armrest 1, which is more conducive to placing items.

[0033] Specifically, the armrest 1 is movably mounted on a support base 2, which is used to connect with the seat. The support base 2 itself can extend and retract to raise and lower the armrest 1. The armrest 1 can move in multiple directions on the support base 2. The relevant structure will not be described in detail here. The multi-directional movement not only allows the armrest 1 to adapt to different arm positions, but also allows the small table formed to be moved to different positions of the human body, which is convenient for use in different situations, such as the small table being located in front of or to the side of the human body.

[0034] To be more specific, such as Figure 1-4As shown, the device also includes a shaft 4, which protrudes from the handrail 1 in the front-to-back direction. The tilting support 3 is rotatably connected to the handrail 1 via the shaft 4. A locking mechanism (not shown) is provided between the shaft 4 and the handrail 1 or between the shaft 4 and the tilting support 3. The locking mechanism is configured to keep the tilting support 3 horizontal when an object is placed on it. The shaft 4 can be a single shaft that passes through the handrail 1, or there can be two shafts located at the front and rear ends of the handrail 1, respectively. The shaft 4 can be fixed to the handrail 1 and rotate with the tilting support 3, or it can be fixed to the tilting support 3 and rotate with the handrail 1. 1. Rotation; The presence of the locking mechanism enables the flip support 3 to remain horizontal, thus ensuring the stability of the placement state and allowing items to be smoothly placed on the small table formed by the armrest 1 and the flip support 3; In this embodiment, the shaft 4 is a single rod and is fixedly mounted on the armrest 1, with both ends of the shaft 4 protruding from the armrest 1 and rotatably connected to the flip support 3; The locking mechanism is a Japanese snap hinge, and the locking mechanism is located between the shaft 4 and the flip support 3; The locking mechanism is located between the shaft 4 and the flip support 3, which is more convenient and easier to implement than being located in the armrest 1.

[0035] Furthermore, in the left-right direction, the shaft 4 is positioned near the end of the armrest 1 and above the armrest 1. This is to allow the flip support 3 to flip to a horizontal position to form a small table. The projection of the shaft 4 in the front-back direction is on the armrest 1. Because the device already has an additional flip support 3, it is already slightly abrupt compared to a conventional armrest. This design ensures that the shaft 4 does not protrude from the armrest 1 in the left-right direction, minimizing the abruptness of the arm support device.

[0036] The flip support 3 includes a connecting part 31 and a main body 32. One end of the connecting part 31 is rotatably connected to the shaft 4, and the other end is connected to the main body 32. In the placed state, the main body 32 is located next to the handrail 1. In the normal state, the connecting part 31 protrudes upward from the main body 32. There is a notch 33 between the main body 32 and the connecting part 31. The notch 33 is configured to avoid the handrail 1 when the flip support 3 rotates. The flip support 3 needs to rotate between horizontal and vertical. When rotating, it is easy to interfere with the handrail 1. In order to avoid collision and interference, a notch 33 is provided between the main body 32 and the connecting part 31. There are two connecting parts 31, located at the front and rear ends of the main body 32 respectively. In the placed state, the connecting parts 31 are also located below the upper surface of the main body 32. After the two connecting parts 31 are sleeved onto the two ends of the shaft 4, a Japanese snap hinge is provided between the corresponding connecting parts 31 and the ends of the shaft 4.

[0037] The distance from the end edge of the handrail 1 near the shaft 4 to the shaft 4 is not greater than the length of the connecting part 31 protruding from the main body 32; while further maintaining avoidance, it can also maintain that there is only a small gap or no gap between the flip support 3 and the handrail 1 when the item is placed.

[0038] Furthermore, under normal conditions, the flip support 3 is located below the upper surface of the handrail 1; under normal conditions, the flip support 3 will not affect the normal use of the handrail 1, and the human arm will not be blocked or bumped by the flip support 3 when resting on the handrail 1; the length of the flip support 3 in the front-back direction is greater than the length of the handrail 1; the longer length of the flip support 3 allows the connecting part 31 to be outside the handrail 1, that is, in the front-back direction, the connecting part 31 is located in front of and behind the handrail 1 respectively, which is also to avoid the handrail 1 as much as possible and not hinder the normal use of the handrail 1; of course, the connecting part 31 of the flip support 3 can also be directly rotated to the handrail 1, but the handrail 1 needs to be slotted.

[0039] Because the device has an additional flip support 3, it is relatively abrupt compared to a conventional handrail. In this solution, the abruptness is minimized by setting the position of the shaft 4 and the structure of the flip support 3. Moreover, the position of the shaft 4 and the structure of the flip support 3 work together to ensure that the flip support 3 does not interfere with the handrail 1 when flipped, and at the same time, the gap between the flip support 3 and the handrail 1 is minimized when the object is placed on it.
