Description

Quick release positioning device and its seat

The present invention provides a positioning device and a seat thereof, in particular a positioning device and a seat thereof that are convenient to disassemble and adjust the position.

If the back of the human body is not properly and comfortably supported when sitting for a long time, it will not only cause back pain, but also may cause permanent damage such as spinal deformity. In order to meet the needs of passengers of different heights, the known seats allow users to adjust the relative position of the back cushion and the seat cushion. For example, the seat cushion position can be fixed or loosened by adjusting the bolt rotation. However, the above bolt rotation positioning method is not easy for users to operate.

Another adjustment method is to simply press an object to increase friction so that the user can quickly fix or loosen the seat position. However, the above adjustment method of pressing an object may have insufficient support force after bearing the weight of the human body because there is no interference from a physical object.

In view of the above problems, the main purpose of the present invention is to provide a quick-release positioning device suitable for positioning on a rod having a plurality of positioning grooves. The quick-release positioning device comprises: a clamping ring having a first arc-shaped elastic clamping arm and a second arc-shaped elastic clamping arm, wherein an arc space is formed between the first arc-shaped elastic clamping arm and the second arc-shaped elastic clamping arm. The arc space is provided for the rod to pass through, and the first arc-shaped elastic clamp arm and the second arc-shaped elastic clamp arm define a distance at the end, and the first arc-shaped elastic clamp arm has a through hole; a handle is pivoted to one end of the clamp ring, and the handle can be rotated relative to the end of the clamp ring to present an open state or a buckled state. When the handle is in the buckled state, it will cause The distance is reduced to increase the clamping force of the clamping ring on the rod. When the handle is in the open state, the distance is increased to reduce the clamping force of the clamping ring on the rod. A movable latch assembly is arranged on the clamping ring. The movable latch assembly has a latch, a return spring and a spring. The latch is accommodated in the first arc-shaped elastic clamp arm. The bolt forms an interference state when inserted into any of the plurality of positioning grooves on the rod; wherein, when the handle rotates relative to the end of the clamp ring to present the locking state, the handle causes the bolt to selectively insert into any of the plurality of positioning grooves on the rod through the spring sheet to form the interference state, thereby limiting the quick release positioning device to be positioned on the rod.

In a preferred embodiment, an outer ring set is provided on the outer side of the clamping ring, and the outer ring set has a receiving space, and the receiving space is used to receive the movable latch set.

In a preferred embodiment, the handle has a protrusion, and when the handle is in the engaged state, the protrusion abuts against the spring, so that the pin selectively inserts into any of the plurality of positioning grooves on the rod to form the interference state.

In a preferred embodiment, an inner ring sleeve is provided on the inner side of the clamping ring, and the inner ring sleeve has an opening, and the opening provides the pin for passing through.

As shown in FIG1 , the novel chair comprises a first rod 1, a seat cushion 2, and a quick-release positioning device 3. The first rod 1 has a plurality of positioning grooves 10. The seat cushion 2 is disposed on a second rod 20. The quick-release positioning device 3 is disposed at the end of the second rod 20 to limit the second rod 20 to be positioned on the first rod 1.

As shown in FIGS. 2 to 7 , the quick-release positioning device 3 includes a clamp ring 30, a handle 32 and a movable latch assembly 34. The clamp ring 30 has a first arc-shaped elastic clamp arm 300 and a second arc-shaped elastic clamp arm 302. An arc space S is formed between the first arc-shaped elastic clamp arm 300 and the second arc-shaped elastic clamp arm 302. The arc space S provides the first rod 1 for passing. The end 301 of the first arc-shaped elastic clamp arm 300 and the end 303 of the second arc-shaped elastic clamp arm 302 are separated by a distance. The first arc-shaped elastic clamp arm 300 has a through hole 305. The handle 32 is pivotally connected to one end of the clamp ring 30 (i.e., the end 301 of the first arc-shaped elastic clamp arm 300 and the end 303 of the second arc-shaped elastic clamp arm 302).

As shown in Figures 6 and 7, the handle 32 can be rotated relative to the ends 301, 303 of the clamping ring 30 to present an open state (as shown in Figure 7) or a snap-on state (as shown in Figures 1-3 and 6). When the handle 32 is in the snap-on state, the distance will be reduced to increase the clamping force of the clamping ring 30 on the first rod 1. When the handle 32 is in the open state, the distance will be increased to reduce the clamping force of the clamping ring 30 on the first rod 1.

The movable latch assembly 34 is disposed on the clamp ring 30. The movable latch assembly 34 has a latch 340, a return spring 342 and a spring 344. The latch 340 is accommodated in the through hole 305 of the first arc-shaped elastic clamp arm 300. The latch 340 forms an interference state when inserted into any of the plurality of positioning grooves 10 on the first rod 1. As shown in FIG. 7, the latch 340 can be released from the interference state by the force applied by an external user and the elastic force of the return spring 342, the spring 344, the first arc-shaped elastic clamp arm 300 and the second arc-shaped elastic clamp arm 302.

When the handle 32 rotates relative to the end of the clamp ring 30 to present the buckled state, the handle 32 causes the latch 340 to selectively insert into any of the plurality of positioning grooves 10 on the first rod 1 through the spring 344 to form the interference state, thereby limiting the quick release positioning device to be positioned on the first rod 1.

In a preferred embodiment, an outer ring set is provided on the outer side of the clamp ring 30, and the outer ring set has a receiving space, and the receiving space is used to receive the movable latch set 34.

In a preferred embodiment, the handle 32 has a protrusion 320. When the handle 32 is in the buckled state, the protrusion 320 abuts against the spring 344, so that the pin 340 selectively inserts into any of the plurality of positioning grooves 10 on the rod to form the interference state.

In a preferred embodiment, an inner ring sleeve 5 is provided on the inner side of the clamp ring 30, and the inner ring sleeve 5 has an opening 50, and the opening 50 provides a passage for the latch 340.

In summary, the novel quick-release positioning device and the seat thereof provide the user with a fastening state presented by rotating the handle 32 relative to the ends 301, 303 of the clamping ring 30, so as to quickly increase the clamping force of the clamping ring 30 on the first rod 1, and at the same time, insert the latch 340 into the plurality of positioning grooves 10 to achieve the interference of a substantial object. In this way, after bearing the weight of the human body, the seat can not only be supported by the clamping force of the clamping ring 30 on the first rod 1, but also can achieve the guarantee of double support by the substantial object interference formed by the insertion of the latch 340 into the plurality of positioning grooves 10.

Although the embodiments of the present invention are disclosed as described above, they are not intended to limit the present invention. Anyone familiar with the relevant technology can make some changes to the shape, structure, features and spirit described in the scope of application of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be subject to the scope of the patent application attached to this specification.
