A sliding assembly for a seat that facilitates locking and unlocking of a position

Abstract

This invention discloses a sliding assembly for a seat that facilitates locking and unlocking. Its structure is simple and easy to implement. The self-resetting transmission mechanism and its pull cable facilitate the upward movement of the blocking member during reset, allowing it to extend into the limiting hole / groove to lock the upper seat. Simultaneously, pulling the pull cable causes the self-resetting transmission mechanism to move the blocking member downward, disengaging it from the limiting hole / groove to unlock the upper seat. This achieves both self-resetting locking and manual unlocking via the pull cable, offering good practicality. Furthermore, the pull cable can be repositioned to a location convenient for user operation, making its design easy to implement. In practice, a pull cable handle can be installed at a user-friendly location. Additionally, the blocking member includes a connecting seat and a blocking body, allowing for the connection of a blocking body of suitable height to the connecting seat as needed, thus improving its applicability.

Description

Technical Field

[0001] This invention relates to a sliding assembly for a seat that facilitates position locking and unlocking. Background Technology

[0002] Currently, some office chairs are equipped with adjustment devices that lock after adjusting the seat's forward and backward position. These devices mainly use a rack and pinion assembly and a movable pin assembly. The movable pin is unlocked by pulling the lever away from the rack, and the pin is locked by a return spring. This method uses a large number of parts, resulting in relatively high costs and time-consuming installation. In addition, CN217309627U discloses a sliding assembly with a position locking function, which uses a swing rod to control the unlocking. In practice, the swing rod needs to pass through the transverse through hole of the lower seat, and its tail end is located on the left or right side. This method has limitations in assembly, such as being inconvenient to place at the lower front or in other positions on the seat. It is necessary to solve this problem. Summary of the Invention

[0003] The present invention overcomes the shortcomings of the above-mentioned technologies and provides a sliding assembly for a seat that facilitates position locking and unlocking.

The blocking member 3 includes a connecting seat 301 and a blocking body 302 connected and fixed to the connecting seat 301. The self-resetting transmission mechanism 4 is used to drive the connecting seat 301 to move up and down and for driving the connecting seat 301 to move upward when resetting.

[0006] Preferably, the self-resetting transmission mechanism 4 further includes a movable seat 42 capable of moving laterally back and forth, a swing member 43 for driving the movable seat 42 to move laterally back and forth by swinging back and forth, and an elastic reset member 44 for elastically driving the movable seat 42 to reset or elastically driving the swing member 43 to reset so as to reset the self-resetting transmission mechanism 4. One arm of the swing member 43 is connected to the movable seat 42 and the other arm is connected to the pull wire 41. A transmission structure 45 is provided between the movable seat 42 and the connecting seat 301 so as to allow the connecting seat 301 to move up and down when the movable seat 42 moves laterally back and forth.

[0007] Preferably, the swing element 43 is a torsion spring.

[0008] Preferably, the elastic reset member 44 is a reset torsion spring used to drive the swing member 43 to swing in one direction so as to reset the self-resetting transmission mechanism 4.

The transmission structure 45 includes a protrusion 451 provided on the outer wall of the connecting seat 301 and a guide groove 452 provided on the movable seat 42 for the protrusion 451 to extend into. When the movable seat 42 moves back and forth laterally, the protrusion 451 is driven to move up and down through the guide groove 452.

[0010] Preferably, the self-resetting transmission mechanism 4 further includes a first seat body 46 for connecting and fixing to the lower seat 1. The first seat body 46 is provided with a first vertical channel 461 for the connecting seat 301 to be inserted from top to bottom and for vertical guiding movement therein. The connecting seat 301 is provided with protrusions 451 on both the front and rear outer side walls.

The self-resetting transmission mechanism and its pull cable facilitate the upward movement of the blocking member during reset, allowing it to extend into the limiting hole / groove to lock the upper seat. It also facilitates the downward movement of the blocking member by pulling the pull cable, allowing it to disengage from the limiting hole / groove and unlock the upper seat. This achieves both self-resetting locking and manual unlocking via the pull cable, offering good practicality. Furthermore, the pull cable can be repositioned to a location convenient for user operation, making its design easy to implement. Specifically, a pull cable handle can be installed at a user-friendly location. Additionally, the blocking member includes a connecting seat and a blocking body, allowing for the connection of a suitable height to the connecting seat, improving its applicability.

[0016] 2.

[0024] The following examples further illustrate the features and other related characteristics of the present invention in detail, to facilitate understanding by those skilled in the art:

[0025] like Figures 1 to 7As shown, a sliding assembly for a seat that facilitates locking and unlocking includes a lower seat 1. An upper seat 2 capable of moving back and forth is mounted on the upper end of the lower seat 1. The lower end of the upper seat 2 is provided with a plurality of limiting holes / limiting grooves 21 arranged back and forth. The lower seat 1 is provided with a blocking member 3 for moving upward to extend into the limiting holes / limiting grooves 21 to lock the upper seat 2 in a certain position and for moving downward to disengage from the limiting holes / limiting grooves 21 to unlock the upper seat 2 in a certain position. The lower seat 1 is provided with a self-resetting transmission mechanism 4 for driving the blocking member 3 to move up and down and for driving the blocking member 3 to move upward when resetting. The self-resetting transmission mechanism 4 is provided with a pull cable 41 for pulling the self-resetting transmission mechanism 4 to drive the blocking member 3 to move downward when pulled. The blocking member 3 includes a connecting seat 301 and a blocking body 302 connected and fixed to the connecting seat 301. The self-resetting transmission mechanism 4 is used to drive the connecting seat 301 to move up and down and for driving the connecting seat 301 to move upward when resetting.

[0026] As described above, the structure of this invention is simple and easy to implement. The self-resetting transmission mechanism 4 and its pull cable 41 facilitate the upward movement of the blocking member 3 during reset, allowing it to extend into the limiting hole / limiting groove 21 to lock the upper seat 2 in position. They also facilitate the downward movement of the blocking member 3 when the pull cable 41 is pulled, allowing it to disengage from the limiting hole / limiting groove 21 and unlock the upper seat 2. This achieves the functions of self-resetting locking and manual unlocking by pulling the pull cable 41, providing good practicality. Furthermore, the pull cable 41 can be repositioned to a location convenient for user operation, making its design easy to implement. In specific implementations, a pull cable handle can be installed at a convenient location for user operation. Additionally, the blocking member 3 includes a connecting seat 301 and a blocking body 302, allowing the connecting seat 301 to be connected to a blocking body 302 of suitable height according to actual needs, providing good applicability.

[0027] like Figure 3 As shown, in a specific implementation, the self-resetting transmission mechanism 4 further includes a movable seat 42 capable of moving laterally back and forth, a swinging member 43 for driving the movable seat 42 to move laterally back and forth by swinging back and forth, and an elastic reset member 44 for elastically driving the movable seat 42 to reset or elastically driving the swinging member 43 to reset so as to reset the self-resetting transmission mechanism 4. One arm of the swinging member 43 is connected to the movable seat 42 and the other arm is connected to the pull wire 41. A transmission structure 45 is provided between the movable seat 42 and the connecting seat 301 so as to allow the connecting seat 301 to move up and down when the movable seat 42 moves laterally back and forth.

[0028] As described above, pulling the cable 41 causes the swing member 43 to swing in one direction, thereby moving the movable seat 42 in one direction. In this way, the movable seat 42 drives the blocking member 3 to move downward through the transmission structure 45 to unlock. When the cable 41 is released, under the action of the elastic reset member 44, the self-resetting transmission mechanism 4 resets and drives the blocking member 3 to move upward to lock. This is easy to implement.

[0029] As described above, in a specific implementation, the swing member 43 is a torsion spring. In a specific implementation, the torsion spring can be sleeved on the column, and then one arm of the torsion spring is connected to the movable seat 42 and the other arm is connected to the pull wire 41. This is convenient to implement. When the pull wire 41 is pulled, the torsion spring can be driven to swing in one direction, thereby driving the movable seat 42 to move in one direction. In this way, the movable seat 42 drives the blocking member 3 to move downward through the transmission structure 45 to unlock.

[0030] As described above, in a specific implementation, the elastic reset member 44 is a reset torsion spring used to drive the swing member 43 to swing in one direction so that the self-resetting transmission mechanism 4 can be reset. In a specific implementation, the reset torsion spring can be sleeved on the column, and then one arm of the reset torsion spring can be pressed against the fixed object, and the other arm can be connected to the swing member 43 to drive the swing member 43 to swing in one direction, which is convenient to implement.

[0031] As described above, in specific implementation, the connecting seat 301 guides the vertical movement, and the transmission structure 45 includes a protrusion 451 provided on the outer wall of the connecting seat 301 and a guide groove 452 provided on the movable seat 42 for the protrusion 451 to extend into. When the movable seat 42 moves back and forth laterally, the protrusion 451 is driven to move up and down through the guide groove 452, which is convenient to implement.

[0032] As described above, in a specific implementation, the self-resetting transmission mechanism 4 further includes a first seat body 46 for connecting and fixing to the lower seat 1. The first seat body 46 is provided with a first vertical channel 461 for the connecting seat 301 to be inserted from top to bottom and for vertical guiding movement therein. The connecting seat 301 is provided with protrusions 451 on both the front and rear outer side walls. The first vertical channel 461 is provided with a first limiting notch 4611 for supporting the protrusions 451 on the corresponding side upwards and not obstructing the protrusions 451 from extending into the corresponding guide groove 452. The movable seat 42 is provided with a limiting opening 421 for easy fitting onto the outer wall of the first vertical channel 461 and for easy horizontal back-and-forth movement of the movable seat 42. The guide groove 452 is provided on the side wall of the limiting opening 421.

[0033] As described above, the arrangement of the first seat 46 in this case facilitates the connection of the blocking member 3 and the movable seat 42, and makes it easier to assemble the self-resetting transmission mechanism 4 and then connect it as a whole to the lower seat 1, which is beneficial to the specific implementation.

[0034] As described above, in a specific implementation, the movable seat 42 is sleeved on the outer wall of the first vertical channel 461 from bottom to top, and the first seat body 46 is provided with a first limiting part 462 for preventing the movable seat 42 from arbitrarily falling out downwards.

[0035] As described above, in a specific implementation, the lower seat 1 is provided with a first vertical through hole 11 located below the limiting hole / limiting groove 21 for the blocking member 3 to move up and down, and the self-resetting transmission mechanism 4 is provided on the bottom surface of the lower seat 1 for easy implementation.

[0036] like Figure 6 , Figure 7 As shown, in a specific implementation, the connecting seat 301 is provided with an upward-facing slot 3011 for the blocking member 3 to be inserted into, which facilitates connection.

[0037] As stated above, this case protects a sliding assembly for a seat that facilitates position locking and unlocking, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
