Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The regional damping device for a glider and the glider of the present utility model will be described with reference to fig. 1 to 6.

As shown in fig. 1 to 5, the regional damping device for a glider according to the embodiment of the present utility model includes damping rubber 210, an adjusting bracket 110, a first roller 111 and a second roller 112. Wherein the damping rubber 210 is connected to the support frame 200 of the glider, and a first contact end 211 and a second contact end 212 are formed on the damping rubber 210; the adjusting frame 110 is connected to the chair cover 100 of the hanging chair; the first roller 111 and the second roller 112 are respectively disposed at two ends of the adjusting frame 110 and are rotatably connected with the adjusting frame 110; the first roller 111 is adapted to contact the first contact end 211 to create damping during the first roller 111 approaching the first contact end 211; the second roller 112 is adapted to contact the second contact end 212 to create damping during the second roller 112 approaching the second contact end 212.

According to the regional damping device for the glider provided by the embodiment of the utility model, the first contact end 211 and the second contact end 212 on the damping rubber 210 and the first roller 111 and the second roller 112 on the adjusting frame 110 are arranged, and in the process that the first roller 111 is close to the first contact end 211 or the second roller 112 is close to the second contact end 212, the rollers are contacted with the damping rubber 210 to generate damping, so that when the chair cover 100 rotates to a position close to the first contact end 211 or the second contact end 212 relative to the supporting frame 200, the movement speed is slowed down under the damping effect, and therefore vibration and noise caused by impact when the chair cover 100 is opened and closed are reduced, and meanwhile, the safety problem possibly caused by sudden compression of the chair cover 100 and handrails is avoided.

Specifically, as shown in fig. 2, 3 and 5, the damping rubber 210 is connected to the support frame 200 of the glider through the rubber fixing frame 220 and the corresponding fastening members for contacting with the first roller 111 or the second roller 112 to generate damping. A first contact end 211 and a second contact end 212 are formed on the damping rubber 210. It is easy to understand that the first contact end 211 and the second contact end 212 are protruded relative to other positions on the damping rubber 210, so that the first contact end and the second contact end can interfere with the movement track of the first roller 111 or the second roller 112, thereby providing conditions for the damping rubber 210 to be extruded by the rollers.

For the above-mentioned fastening members for fixing the damping rubber 210 and the rubber fixing frame 220, those skilled in the art can reasonably select, for example, bolts, etc., according to practical situations, and the embodiment is not limited thereto. In other embodiments, the damping rubber 210 may be attached to the support frame 200 by bonding or the like.

As shown in fig. 2 to 4, the chair cover 100 is provided with an adjusting frame 110. The adjustment frame 110 is formed as an elongated plate member connected to the chair cover 100 by fasteners. A first roller 111 and a second roller 112 are respectively connected to both ends of the adjustment frame 110. It will be appreciated that the first roller 111 and the second roller 112 are adapted to rotate relative to the adjustment frame 110.

In this embodiment, the first roller 111 and the second roller 112 are both connected to the adjusting frame 110 through a fixing shaft 120, and a locking spacer 130 is disposed between the fixing shaft 120 and the adjusting frame 110. The anti-loose washer 130 is used to prevent the loosening caused by the long-term rotation of the first roller 111 and the second roller 112, so as to ensure the fastening connection of the first roller 111 and the second roller 112 on the adjusting frame 110.

In other embodiments, the first roller 111 and the second roller 112 may be connected to the adjusting frame 110 by other possible shafts, pins, etc. as long as the first roller 111 and the second roller 112 can be rotatably connected to two ends of the adjusting frame 110, and those skilled in the art can reasonably select according to practical needs.

In an actual use scenario of the glider, it is often the case that the chair cover 100 rotates relative to the support frame 200. For example, when a user needs to sit on the hanging chair, the chair cover 100 needs to be opened backward to expose the armrests and the seat; when the hanging chair is not needed, the chair cover 100 can be rotated forwards to cover the armrests and the seats, so that the effects of reducing wind resistance and protecting can be achieved. When the chair cover 100 rotates relative to the supporting frame 200, the adjusting frame 110 is adapted to follow the chair cover 100 to rotate relative to the damping rubber 210 connected to the supporting frame 200, and further, the first roller 111 or the second roller 112 at both ends of the adjusting frame 110 can contact with the first contact end 211 or the second contact end 212 of the damping rubber 210, thereby generating damping.

Specifically, as shown in fig. 1, when the chair cover 100 rotates relative to the supporting frame 200 in a direction approaching the first contact end 211, the first roller 111 approaches the first contact end 211 and contacts the first contact end 211 to generate damping; when the chair cover 100 rotates relative to the support frame 200 in a direction approaching the second contact end 212, the second roller 112 approaches the second contact end 212 and contacts the second contact end 212 to generate damping. In particular, during the movement of the first roller 111 close to the first contact end 211, starting from the contact with the first contact end 211, the pressure with the damping rubber 210 increases progressively, the damping produced also increases progressively; conversely, during movement of the first roller 111 away from the first contact end 211, the pressure against the damping rubber 210 decreases gradually, and the resulting damping decreases gradually until the damping decreases to zero upon separation 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 herein.

By this arrangement, when the chair cover 100 is rotated relative to the supporting frame 200 to a position close to the first contact end 211 or the second contact end 212, the regional damping device for the glider reduces the movement speed of the chair cover 100 through damping, thereby realizing the functions of buffering, vibration reduction and noise reduction, and simultaneously avoiding the safety problem possibly caused by the sudden compression of the chair cover 100 and the armrests.

According to the regional damping device for the glider provided by the embodiment of the utility model, the section of the damping rubber 210 is elliptical along the plane perpendicular to the chair cover rotating shaft 140; the sum of the oval-shaped half-length axis length and the radius of the first roller 111 is larger than the radius of gyration of the first roller 111; the sum of the oval-shaped half-length axis length and the radius of the second roller 112 is greater than the radius of gyration of the second roller 112.

As shown in fig. 1, the damping rubber 210 in the present embodiment is provided in the form of an oval in cross section perpendicular to the seat cover rotation axis 140. The axle center of the chair cover rotating shaft 140 coincides with the center of the ellipse. It is readily understood that the two ends of the major axis of the oval shape are the first contact end 211 and the second contact end 212 described above. In order to allow the first roller 111 or the second roller 112 to be in contact with both ends of the major axis of the oval shape to generate damping, the radius of gyration of the first roller 111 or the second roller 112 needs to be controlled within a certain range. Specifically, the radius of gyration of the first roller 111 is smaller than the sum of the half-length axial length of the ellipse and the radius of the first roller 111; the radius of gyration of the second roller 112 is less than the sum of the elliptical half-length axis length and the radius of the second roller 112.

It should be noted that, in other embodiments, the damping rubber 210 may be provided in other forms, such as a tapered surface with a variable cross section or a cam structure with a regional contact, if the damping is capable of reducing the movement speed of the chair cover 100 near the two contact ends.

As shown in fig. 4, the adjusting frame 110 is provided with a long hole, and the adjusting frame 110 is adapted to move relative to the chair cover 100 along the length direction of the long hole. That is, by providing the long hole, the whole translation of the adjusting frame 110 toward or away from the axis of the chair cover rotating shaft 140 can be realized, so that the compression amount of the damping rubber 210 by the first roller 111 and the second roller 112 can be adjusted, and the damping size can be changed. Specifically, the adjusting frame 110 is translated towards the axial direction of the chair cover rotating shaft 140, the compression amount of the damping rubber 210 by the first roller 111 and the second roller 112 is increased, and the damping is increased; conversely, the adjusting frame 110 is translated away from the axial direction of the chair cover rotating shaft 140, the compression amount of the damping rubber 210 by the first roller 111 and the second roller 112 is reduced, and the damping is reduced.

In addition, the long hole of the adjusting bracket 110 translates the adjusting bracket 110 toward the axis of the chair cover rotating shaft 140, thereby manually compensating the surface abrasion amount of the damping rubber 210. In some embodiments, the compensation for the amount of wear of the damping rubber 210 may also be automatically achieved by a spring or the like.

According to the regional damping device for the glider provided by the embodiment of the utility model, the regional damping device for the glider further comprises a rubber fixing frame 220, the damping rubber 210 is nested in the rubber fixing frame 220, and an anti-rotation surface is arranged between the damping rubber 210 and the rubber fixing frame 220.

As shown in fig. 5, the damping rubber 210 is connected to the support frame 200 through a rubber fixing frame 220. The rubber mount 220 is adapted to be coupled to the support frame 200 by a fastener, formed in a ring-like structure. The outer side of the rubber mount 220 is used to support the damping rubber 210, in other words, the damping rubber 210 is nested in the rubber mount 220. An anti-rotation surface is further formed between the damping rubber 210 and the rubber fixing frame 220 to prevent the damping rubber 210 and the rubber fixing frame 220 from rotating relatively, so that the regional damping device for the glider can work normally. It will be appreciated that the inner anti-rotation surface of the damping rubber 210 matches the outer anti-rotation surface of the rubber mount 220.

The anti-rotation surface may be at least one of a convex surface, a concave surface, and a flat surface, and this embodiment is not particularly limited as long as the purpose of preventing the damping rubber 210 and the rubber mount 220 from rotating relative to each other can be achieved. In some embodiments, the damping rubber 210 and the rubber mount 220 are interference fit to perform the same function as described above.

As shown in fig. 5, a bearing 230 is provided inside the rubber mount 220. The bearing 230 is used to support the seat cover pivot shaft 140. In the present embodiment, two bearings 230 are provided. In other embodiments, the number of bearings 230 may be adjusted for better support.

According to the regional damping device for a glider provided by the embodiment of the utility model, the supporting frame 200 is provided with a circumferentially arranged long hole, and the rubber fixing frame 220 is suitable for rotating relative to the supporting frame 200 along the arrangement direction of the long hole.

As shown in fig. 5, long holes are formed in the portion of the support frame 200 for connecting the rubber mount 220 by fasteners, the long holes being arranged along the circumferential direction of the rubber mount 220. By providing the long hole, the rubber fixing frame 220 can be rotated relative to the supporting frame 200, so that the angle of the damping rubber 210 nested on the rubber fixing frame 220 can be finely adjusted, and the damping area of the first contact end 211 and the damping area of the second contact end 212 can be synchronously distributed.

According to an embodiment of the present utility model, there is provided a regional damping device for a glider, the chair cover 100 being adapted to switch between an extreme position and a transitional position relative to the support frame 200; in the transition position, the first roller 111 and the second roller 112 are adapted to be separated from the damping rubber 210.

In this embodiment, in order to play a certain role of buffering, an anti-collision rubber is provided at the rear side of the supporting frame 200. The rotation of the chair cover 100 relative to the supporting frame 200 is limited by the anti-collision rubber and the armrests, so that the chair cover 100 is in a limit position of movement when the chair cover 100 is opened backward to be in contact with the anti-collision rubber, in an opened state, and when the chair cover 100 is covered on the armrests and the seat forward, in a closed state. When the chair cover 100 transitions from the open state to the closed state, or from the closed state to the open state, the chair cover 100 is in the transition position.

In the transition position, the first roller 111 and the second roller 112 are not in contact with the damping rubber 210, so that the user can change the state of the chair cover 100 more conveniently. In the process of switching the chair cover 100 from the transition position to the limit position, the adjusting frame 110 rotates relative to the damping rubber 210 along with the chair cover 100, and as the turning radiuses of the first roller 111 and the second roller 112 at the two ends of the adjusting frame 110 gradually interfere with the damping rubber 210 in a regional way, the first roller 111 and the second roller 112 gradually compress the damping rubber 210 to form damping, so that regional damping effect is realized, and the effects of buffering, vibration reduction, noise reduction and safety enhancement are achieved. It should be noted that the compression amount of the damping rubber 210 by the first roller 111 and the second roller 112 is 2 mm at maximum.

The embodiment of the utility model also provides a hanging chair, which comprises the regional damping device for the hanging chair.

According to the hanging chair provided by the embodiment of the utility model, the first contact end 211 and the second contact end 212 on the damping rubber 210 and the first roller 111 and the second roller 112 on the adjusting frame 110 are arranged, and in the process that the first roller 111 is close to the first contact end 211 or the second roller 112 is close to the second contact end 212, the rollers are contacted with the damping rubber 210 to generate damping, so that when the chair cover 100 rotates to a position close to the first contact end 211 or the second contact end 212 relative to the supporting frame 200, the movement speed is slowed down under the damping action, and therefore vibration and noise caused by impact when the chair cover 100 is opened and closed are reduced, and meanwhile, the safety problem possibly caused by sudden compression of the chair cover 100 and armrests is avoided.

According to the hanging chair provided by the utility model, a buffer structure is arranged between the chair cover 100 and the supporting frame 200 in the limit position.

Specifically, as shown in fig. 6, in an opened state in which the chair cover 100 is opened backward to be in contact with the rear side of the supporting frame 200, the rear side of the supporting frame 200 is provided with a first buffer structure 251; in the closed state in which the chair cover 100 is forward-covered on the seat, the chair lift is provided with a second buffer structure 252. The first and second buffer structures 251 and 252 may play a role in reducing vibration and noise to some extent. 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 choose other suitable cushioning structures as appropriate, so long as they function in the same manner as described above.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
