Description

Technical Field

[0001] The present invention relates to the technical field of passenger ropeways, in particular to a regional damping device for a hanging chair and the hanging chair. Background Art

[0002] A chairlift is a common device in passenger ropeway technology. It consists of a seat cover and a support frame. The cover can rotate relative to the support frame around a rotation axis to open and close. Currently, when opening or closing, the cover of existing chairlifts on the market gradually accelerates due to the force applied by the user and their own weight, stopping when they reach the open or closed position due to an impact. This causes a lot of noise and vibration, which can easily damage the chairlift and cause users to be pinched, posing a significant safety hazard.

[0003] To address this problem, most current solutions are to have the seat cover hit the rubber buffer on the back of the backrest when it is open, and to have it hit the armrests on both sides of the hanging chair when it is closed. This method reduces the impact noise to a certain extent, but the vibration caused by the impact is still unavoidable, and there is still a risk of pinching the user. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention provides a regional damping device for a hanging chair and the hanging chair.

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] The following combination Figures 1 to 6 The present invention describes a regional damping device for a hanging chair and a hanging chair.

[0031] like Figures 1 to 5 As shown, the regional damping device for a hanging chair provided by an embodiment of the present invention includes a damping rubber 210, an adjustment frame 110, a first roller 111, and a second roller 112. The damping rubber 210 is connected to the support frame 200 of the hanging chair and is formed with a first contact end 211 and a second contact end 212; the adjustment frame 110 is connected to the chair cover 100 of the hanging chair; the first roller 111 and the second roller 112 are respectively arranged at both ends of the adjustment frame 110 and are rotatably connected to the adjustment frame 110; when the first roller 111 approaches the first contact end 211, the first roller 111 is adapted to contact the first contact end 211 to generate damping; when the second roller 112 approaches the second contact end 212, the second roller 112 is adapted to contact the second contact end 212 to generate damping.

[0032] The regional damping device for a hanging chair provided in an embodiment of the present invention is configured by arranging a first contact end 211 and a second contact end 212 on the damping rubber 210 and a first roller 111 and a second roller 112 on the adjustment frame 110. In the process of the first roller 111 approaching the first contact end 211 or the second roller 112 approaching the second contact end 212, the rollers contact the damping rubber 210 to generate damping, so that when the chair cover 100 rotates to a position corresponding to the first contact end 211 or the second contact end 212 relative to the support frame 200, the movement speed is slowed down under the action of damping, thereby reducing the vibration and noise caused by the impact when the chair cover 100 is opened and closed, and avoiding the safety problems that may be caused by the sudden compression of the chair cover 100 and the armrest.

[0033] Specifically, if Figure 2 、 Figure 3 、 Figure 5 As shown, the damping rubber 210 is connected to the support frame 200 of the hanging chair via a rubber fixing bracket 220 and corresponding fasteners. It is used to contact the first roller 111 or the second roller 112 to generate damping. The damping rubber 210 is formed with a first contact end 211 and a second contact end 212. It will be readily understood that the first contact end 211 and the second contact end 212 are relatively protruding relative to other locations on the damping rubber 210. This allows them to interfere with the motion trajectory of the first roller 111 or the second roller 112, creating conditions for the rollers to squeeze the damping rubber 210 to generate damping.

[0034] Regarding the fasteners used to secure the damping rubber 210 and the rubber fixing frame 220, those skilled in the art may reasonably select, for example, bolts, etc., according to actual conditions, and this embodiment does not specifically limit this. In other embodiments, the damping rubber 210 may also be connected to the support frame 200 by bonding or other methods.

[0035] like Figures 2 to 4 As shown, an adjustment frame 110 is provided on the seat cover 100. The adjustment frame 110 is formed as an elongated plate and is connected to the seat cover 100 via fasteners. A first roller 111 and a second roller 112 are connected to the ends of the adjustment frame 110, respectively. It is understood that the first roller 111 and the second roller 112 are adapted to rotate relative to the adjustment frame 110.

[0036] In this embodiment, the first roller 111 and the second roller 112 are both connected to the adjustment frame 110 via a fixed shaft 120, and an anti-loosening washer 130 is provided between the fixed shaft 120 and the adjustment frame 110. The anti-loosening washer 130 is used to prevent the first roller 111 and the second roller 112 from loosening due to long-term rotation, thereby ensuring the tight connection of the first roller 111 and the second roller 112 to the adjustment frame 110.

[0037] In some other embodiments, the first roller 111 and the second roller 112 may also be connected to the adjustment frame 110 through other possible structures such as shafts, pins, etc., as long as the first roller 111 and the second roller 112 can be rotatably connected to the two ends of the adjustment frame 110. Those skilled in the art may make reasonable choices based on actual needs.

[0038] In the actual use of a hanging chair, the chair cover 100 often rotates relative to the support frame 200. For example, when a user needs to ride in a hanging chair, the chair cover 100 needs to be opened backward to expose the armrests and seat. When the hanging chair is no longer in use, the chair cover 100 can be rotated forward to cover the armrests and seat to reduce wind resistance and provide protection. When the chair cover 100 rotates relative to the support frame 200, the adjustment frame 110 is adapted to rotate with the chair cover 100 relative to the damping rubber 210 connected to the support frame 200. Furthermore, the first roller 111 or the second roller 112 at both ends of the adjustment frame 110 can contact the first contact end 211 or the second contact end 212 of the damping rubber 210, thereby generating damping.

[0039] Specifically, if Figure 1As shown, when the seat cover 100 rotates relative to the support frame 200 toward the first contact end 211, the first roller 111 approaches the first contact end 211 and contacts the first contact end 211, generating damping. When the seat cover 100 rotates relative to the support frame 200 toward the second contact end 212, the second roller 112 approaches the second contact end 212 and contacts the second contact end 212, generating damping. Specifically, as the first roller 111 moves toward the first contact end 211, starting from contact with the first contact end 211, the pressure between the first roller 111 and the damping rubber 210 gradually increases, and the damping generated also gradually increases. Conversely, as the first roller 111 moves away from the first contact end 211, the pressure between the first roller 111 and the damping rubber 210 gradually decreases, and the damping generated also gradually decreases, until the damping is reduced to zero when the first roller 111 separates from the first contact end 211. The damping change between the second roller 112 and the second contact end 212 is similar to that of the first roller 111 and will not be described in detail here.

[0040] Through such an arrangement, when the chair cover 100 rotates relative to the support frame 200 to a position corresponding to the first contact end 211 or the second contact end 212, the regional damping device for the hanging chair reduces the movement speed of the chair cover 100 through damping, thereby achieving the functions of buffering, vibration reduction and noise reduction, while avoiding safety problems that may be caused by sudden compression of the chair cover 100 and the armrest.

[0041] According to an embodiment of the present invention, a regional damping device for a hanging chair is provided. Along a plane perpendicular to the chair cover rotation axis 140, the cross-section of the damping rubber 210 is elliptical; the sum of the semi-major axis length of the ellipse and the radius of the first roller 111 is greater than the rotation radius of the first roller 111; the sum of the semi-major axis length of the ellipse and the radius of the second roller 112 is greater than the rotation radius of the second roller 112.

[0042] like Figure 1 As shown, the damping rubber 210 in this embodiment is configured to be in the form of an ellipse along a cross section perpendicular to the seat cover rotation axis 140. The axis of the seat cover rotation axis 140 coincides with the center of the ellipse. It is easy to understand that the two ends of the major axis of the ellipse are the first contact end 211 and the second contact end 212 mentioned above. In order to enable the first roller 111 or the second roller 112 to contact the two ends of the major axis of the ellipse to generate damping, the rotation radius of the first roller 111 or the second roller 112 needs to be controlled within a certain range. Specifically, the rotation radius of the first roller 111 is smaller than the sum of the semi-major axis length of the ellipse and the radius of the first roller 111; the rotation radius of the second roller 112 is smaller than the sum of the semi-major axis length of the ellipse and the radius of the second roller 112.

[0043] It is worth noting that in some other embodiments, under the premise of having two contact ends, the damping rubber 210 can also be set to other forms, such as a wedge-shaped surface with variable cross-section or a cam structure with regional contact, etc., as long as the purpose of reducing the movement speed of the seat cover 100 near the two contact ends through damping can be achieved.

[0044] like Figure 4 As shown, the adjustment frame 110 is provided with an elongated hole, and the adjustment frame 110 is adapted to move relative to the seat cover 100 along the length of the elongated hole. In other words, by providing the elongated hole, the adjustment frame 110 can be translated as a whole toward or away from the axis of the seat cover rotation axis 140, thereby adjusting the amount of compression of the damping rubber 210 by the first roller 111 and the second roller 112, and thereby changing the damping. Specifically, when the adjustment frame 110 is translated toward the axis of the seat cover rotation axis 140, the amount of compression of the damping rubber 210 by the first roller 111 and the second roller 112 increases, thereby increasing the damping; conversely, when the adjustment frame 110 is translated away from the axis of the seat cover rotation axis 140, the amount of compression of the damping rubber 210 by the first roller 111 and the second roller 112 decreases, thereby decreasing the damping.

[0045] Furthermore, manually compensating for surface wear of the damping rubber 210 can be achieved by translating the entire adjustment frame 110 toward the center of the seat cover pivot axis 140 through the slotted hole in the adjustment frame 110. In some embodiments, automatic compensation for wear of the damping rubber 210 can also be achieved through structures such as springs.

[0046] According to an embodiment of the present invention, a regional damping device for a hanging chair further includes a rubber fixing frame 220 , in which the damping rubber 210 is nested, and an anti-rotation surface is provided between the damping rubber 210 and the rubber fixing frame 220 .

[0047] like Figure 5 As shown, the damping rubber 210 is connected to the support frame 200 via a rubber mounting bracket 220. The rubber mounting bracket 220 is adapted to be connected to the support frame 200 via fasteners, forming an annular structure. The outer side of the rubber mounting bracket 220 is used to support the damping rubber 210. In other words, the damping rubber 210 is nested within the rubber mounting bracket 220. An anti-rotation surface is also formed between the damping rubber 210 and the rubber mounting bracket 220 to prevent relative rotation between the damping rubber 210 and the rubber mounting bracket 220, thereby ensuring the proper operation of the regional damping device for the hanging chair. It will be appreciated that the inner anti-rotation surface of the damping rubber 210 matches the outer anti-rotation surface of the rubber mounting bracket 220.

[0048] The anti-rotation surface can be at least one of a convex surface, a concave surface, and a flat surface. This embodiment does not impose any specific limitations on this, as long as it can prevent the damping rubber 210 and the rubber mounting bracket 220 from rotating relative to each other. In some embodiments, the damping rubber 210 and the rubber mounting bracket 220 have an interference fit to achieve the same function as described above.

[0049] like Figure 5 As shown, a bearing 230 is disposed on the inner side of the rubber fixing frame 220. The bearing 230 is used to support the seat cover rotation axis 140. In this embodiment, two bearings 230 are provided. In other embodiments, the number of bearings 230 may be adjusted to provide better support.

[0050] According to an embodiment of the present invention, a regional damping device for a hanging chair is provided. The support frame 200 is provided with circumferentially arranged long holes, and the rubber fixing frame 220 is adapted to rotate relative to the support frame 200 along the setting direction of the long holes.

[0051] like Figure 5 As shown, the portion of the support frame 200 for connecting the rubber mounting frame 220 via fasteners has elongated holes arranged along the circumference of the rubber mounting frame 220. The elongated holes allow the rubber mounting frame 220 to be rotated relative to the support frame 200, thereby fine-tuning the angle of the damping rubber 210 nested in the rubber mounting frame 220 and thereby simultaneously distributing the damping area sizes of the first contact end 211 and the second contact end 212.

[0052] According to an embodiment of the present invention, a regional damping device for a hanging chair is provided, wherein the chair cover 100 is suitable for switching between an extreme position and a transition position relative to the support frame 200; in the transition position, the first roller 111 and the second roller 112 are suitable for being separated from the damping rubber 210.

[0053] In this embodiment, to provide a certain degree of cushioning, an anti-collision rubber is installed on the rear side of the support frame 200. The rotation of the seat cover 100 relative to the support frame 200 is limited by the anti-collision rubber and the armrests. Therefore, when the seat cover 100 is opened rearward and contacts the anti-collision rubber (open state), and when the seat cover 100 is moved forward to cover the armrests and seat (closed state), the seat cover 100 is at the extreme end of its movement. When the seat cover 100 transitions from the open state to the closed state, or vice versa, it is in a transition position.

[0054] In the transition position, the first roller 111 and the second roller 112 do not contact the damping rubber 210, allowing the user to more easily change the state of the seat cover 100. As the seat cover 100 switches from the transition position to the extreme position, the adjustment frame 110 rotates relative to the damping rubber 210 following the seat cover 100. Because the rotation radius of the first roller 111 and the second roller 112 at both ends of the adjustment frame 110 gradually interferes with the damping rubber 210 in a regional manner, the first roller 111 and the second roller 112 gradually compress the damping rubber 210 to form damping, achieving a regional damping effect, which plays a role in buffering, reducing vibration, reducing noise, and enhancing safety. It is worth noting that the maximum compression of the damping rubber 210 by the first roller 111 and the second roller 112 is 2 mm.

[0055] An embodiment of the present invention further provides a hanging chair, comprising the regional damping device for a hanging chair as described above.

[0056] The hanging chair provided by the embodiment of the present invention is provided with a first contact end 211 and a second contact end 212 on the damping rubber 210 and a first roller 111 and a second roller 112 on the adjustment frame 110. In the process of the first roller 111 approaching the first contact end 211 or the second roller 112 approaching the second contact end 212, the rollers contact the damping rubber 210 to generate damping, so that when the chair cover 100 rotates to a position corresponding to the first contact end 211 or the second contact end 212 relative to the support frame 200, the movement speed is slowed down under the action of damping, thereby reducing the vibration and noise caused by the impact when the chair cover 100 is opened and closed, and avoiding the safety problems that may be caused by the sudden compression of the chair cover 100 and the armrests.

[0057] According to the hanging chair provided by the present invention, a buffer structure is provided between the chair cover 100 and the support frame 200 at the extreme position.

[0058] Specifically, if Figure 6 As shown, when the chair cover 100 is opened backward and contacts the rear side of the support frame 200, a first buffer structure 251 is provided on the rear side of the support frame 200. When the chair cover 100 is closed and covers the seat forward, a second buffer structure 252 is provided on the hanging chair. The first and second buffer structures 251, 252 can help reduce vibration and noise. In this embodiment, the first buffer structure 251 is anti-collision rubber, and the second buffer structure 252 is an armrest. Of course, in other embodiments, those skilled in the art may also select other suitable buffer structures according to the specific circumstances, as long as they can achieve the same effect as described above.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
