Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a multifunctional armrest. 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 a multifunctional handrail, including a support member for supporting a human arm. A receiving groove is formed in the support member, allowing a moving part to reside within the groove in its normal state. The handrail has a conventional overall design, providing a place for the user to rest their arm. The moving part is slidably positioned within the receiving groove, engaging with the support member. When switching from the normal state to the extended state, the moving part can be simply pulled out of the receiving groove. In the extended state, the moving part is located beside the support member, forming a small table for the user to place items, thus realizing the multifunctionality of the handrail.

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

[0008] A multifunctional handrail includes a support member for supporting a human arm, the support member having a laterally open receiving groove, a moving member being disposed in the receiving groove, and the moving member being slidably disposed in the receiving groove; the multifunctional handrail has a normal state and an extended state; in the normal state, the moving member is placed in the receiving groove; in the extended state, the moving member slides out of the receiving groove and is located beside the support member.

[0009] A receiving groove is provided in the support component so that the moving component can be placed in the receiving groove in the normal state. The handrail has a conventional shape and provides a place for the user to rest their arm. The moving component is slidably set in the receiving groove and slides in cooperation with the support component. When switching from the normal state to the extended state, the moving component can be pulled to slide out of the receiving groove. In the extended state, the moving component is located next to the support component, so that the two together form a small table for the user to place items, realizing the multi-functionality of the handrail.

[0010] Preferably, the receiving groove is equipped with a telescopic rod, and the moving part is mounted on the telescopic rod. The telescopic rod enables the moving part to slide within the receiving groove.

[0011] Preferably, the moving part and the telescopic rod are rotatably configured. In the extended state, the moving part is located beside the support and flips upward onto the telescopic rod, with the upper surface of the moving part roughly flush with the upper surface of the support. This rotatable configuration allows the moving part to flip, placing it below the upper surface of the support. After flipping, the moving part raises its height, making its upper surface roughly flush with the upper surface of the support, thus making the small table more effective at securing items.

[0012] Preferably, the moving part includes a main body and an extension. The main body is connected to the telescopic rod, and the extension protrudes from the main body along the length of the support. In the extended state, the extension rests against the telescopic rod from top to bottom. The resting of the extension against the telescopic rod limits the movement of the moving part, keeping it at that height and increasing the stability of the small table during use.

[0013] Preferably, the main body is provided with a sliding rotation groove, which is arranged along the width direction of the support member; the telescopic rod is arranged in the sliding rotation groove and slides and rotates in cooperation with the main body. The telescopic rod can slide in the sliding rotation groove and also cause the moving part to rotate relative to it. The relative sliding between the two increases the sliding distance of the moving part, so that there is enough space between the moving part and the support member to allow the moving part to flip to the side of the support member, and the rotation of the moving part can be realized without obstruction.

[0014] Preferably, the sliding rotation groove is an elongated groove, which includes a first end and a second end. In the normal state, the extension is located below the telescopic rod and the telescopic rod is located at the first end; in the extended state, the extension is located above the telescopic rod and the telescopic rod is located at the second end.

[0015] Preferably, the telescopic rod includes a first rod and a second rod that are nested together, with one end of the second rod bent and inserted into a sliding rotation groove.

[0016] Preferably, the telescopic rod includes a U-shaped rod, which comprises a rotating part and two telescopic parts located at both ends of the rotating part. A first rod is sleeved or inserted onto the telescopic part, and the first rod is fixedly connected to the support member. A sliding rotating groove extends along the length of the support member, and the rotating part is inserted into the sliding rotating groove. The connection between the U-shaped rod and the moving part is more stable, and the rotating part being located in the sliding rotating groove increases the contact area between the U-shaped rod and the moving part, preventing the moving part from detaching from the telescopic rod.

[0017] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0018] A receiving groove is provided in the support component so that the moving component can be placed in the receiving groove in the normal state. The handrail has a conventional shape and provides a place for the user to rest their arm. The moving component is slidably set in the receiving groove and slides in cooperation with the support component. When switching from the normal state to the extended state, the moving component can be pulled to slide out of the receiving groove. In the extended state, the moving component is located next to the support component, so that the two together form a small table for the user to place items, realizing the multi-functionality of the handrail.

Detailed Implementation

[0029] 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.

[0030] 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.

[0031] 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.

[0032] The specific embodiments of this utility model are as follows:

[0033] like Figure 1-8 As shown, this utility model provides a multifunctional handrail, including a support member 1 for supporting a human arm. The support member 1 has a laterally open receiving groove 11, and a moving member 2 is provided in the receiving groove 11, and the moving member 2 is slidably disposed in the receiving groove 11. The multifunctional handrail has a normal state and an extended state. In the normal state, the moving member 2 is placed in the receiving groove 11. In the extended state, the moving member 2 slides out of the receiving groove 11 and is located next to the support member 1.

[0034] A receiving groove 11 is provided in the support member 1 so that the moving member 2 can be in the receiving groove 11 in the normal state. The armrest is of a conventional style and is provided for the user to rest their arm. The moving member 2 is slidably set in the receiving groove 11 and slides in cooperation with the support member 1. When switching from the normal state to the extended state, the moving member 2 can be pulled directly to slide out of the receiving groove 11. In the extended state, the moving member 2 is located next to the support member 1, so that the two together form a small table for the user to place items, realizing the multi-functionality of the armrest.

[0035] Specifically, the support member 1 is movably mounted on a support base 5, which is used to connect with the seat. The support base 5 itself can extend and retract to realize the lifting and lowering of the support member 1. The support member 1 can move in multiple directions on the support base 5. The relevant structure will not be described in detail here. The multi-directional movement not only allows the support member 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.

[0036] To be more specific, such as Figure 3-9 As shown, a telescopic rod 3 is provided in the receiving groove 11, and a moving member 2 is disposed on the telescopic rod 3. The moving member 2 is slidably disposed in the receiving groove 11 through the telescopic rod 3. The moving member 2 includes a main body 21 and an extension 22. The main body 21 is connected to the telescopic rod 3, and the extension 22 protrudes from the main body 21 along the length direction of the supporting member 1. The moving member 2 and the telescopic rod 3 are also rotatably disposed. A sliding rotation groove 4 is provided on the main body 21, and the sliding rotation groove 4 is disposed along the width direction of the supporting member 1. The telescopic rod 3 is disposed in the sliding rotation groove 4 and slides and rotates in cooperation with the main body 21. The sliding rotation groove 4 is an elongated groove, which includes a first end 41 and a second end 42. In the normal state, the extension 22 is located below the telescopic rod 3 and the telescopic rod 3 is located at the first end 41. In the extended state, the extension 22 is located above the telescopic rod 3 and the telescopic rod 3 is located at the second end 42.

[0037] In its extended state, the moving part 2 is located beside the support 1 and flips upward onto the telescopic rod 3. The extension 22 rests against the telescopic rod 3 from top to bottom, and the upper surface of the moving part 2 is roughly flush with the upper surface of the support 1. The rotating arrangement of the moving part 2 and the telescopic rod 3 allows the moving part 2 to flip. The moving part 2 itself is below the upper surface of the support 1. After flipping, the moving part 2 can raise its own height and make its upper surface roughly flush with the upper surface of the support 1, making the small table more effective at preventing items from falling. The extension 22 rests against the telescopic rod 3 to limit the movement of the moving part 2, keeping it at that height and increasing the stability of the small table during use.

[0038] The existence of the sliding rotation groove 4 allows the telescopic rod 3 to slide in the sliding rotation groove 4 and also allows the moving part 2 to rotate relative to it. The relative sliding of the two can increase the sliding distance of the moving part 2, so that there is enough space between the moving part 2 and the support 1 to allow the moving part 2 to flip to the side of the support 1, and the rotation of the moving part 2 can be achieved without obstruction.

[0039] Furthermore, such as Figure 3 , 5 As shown in Figure 9, the telescopic rod 3 includes a U-shaped rod 31, which includes a rotating part 311 and two telescopic parts 312 located at both ends of the rotating part 311. A first rod 32 is sleeved or inserted on the telescopic part 312. The first rod 32 is fixedly connected to the support member 1. In this embodiment, in order to prevent the moving part 2 from interfering with the first rod 32 when it is stored, the first rod 32 is inserted into the U-shaped rod 31. The sliding rotation groove 4 runs through the length of the support member 1, and the rotating part 311 is inserted into the sliding rotation groove 4. The connection between the U-shaped rod 31 and the moving part 2 is more stable. The rotating part 311 is set in the sliding rotation groove 4 to increase the contact area between the U-shaped rod 31 and the moving part 2, preventing the moving part 2 from separating from the telescopic rod 3. In addition, the telescopic rod 3 can also be a simpler two-set rod, such as the telescopic rod 3 including a first rod 32 and a second rod that are sleeved on each other, with one end of the second rod bent and inserted into the sliding rotation groove 4.

[0040] The operation of the multi-functional armrest when switching states is as follows: When switching from the normal state to the extended state, first pull the moving part 2 out of the receiving groove 11, and there is a gap between the moving part 2 and the supporting part 1. Then, flip the moving part 2 upward and fill the gap. At the same time, the moving part 2 rests on the telescopic rod 3, so that the upper surface of the moving part 2 is roughly flush with the upper surface of the supporting part 1, thereby forming a small table for use.
