Description

Seat rotation positioning structure

The present invention provides a seat rotation positioning structure, which is mainly capable of obtaining a desired seat freely rotating state by a simpler operation of a group which is arranged to rotate or position a seat controlled between the seats. Temporarily set the seat to a limited orientation.

According to the existing chair, in order to meet the average person's best comfort when sitting in, the relevant operators will consider the mechanism for adjusting the activity when manufacturing such a chair, so that the chair can be The seat cushion unit, the seat back unit, the armrest unit... can be adjusted according to the orientation required to improve the use of the chair.

However, the inventors have previously proposed a group setting for the rotation or positioning of the seat, so that the seat is more convenient when it is necessary to adjust the orientation. The rotation or positioning restriction group of the seat comprises: a sleeve is coupled to the upper end of the gas pressure bar, and a ring is sleeved in the inner space of the sleeve, and the top end of the sleeve is covered by a top cover. A portion of the pipe section extending along one side of the sleeve is sequentially inserted into a spring-incorporated rod section, and a hole extending from the one end of the rod section is protruded from the side of the sleeve, and the outwardly facing section of the section is pulled The upper and lower lugs of the corresponding end of the piece are pivotally connected; thereby, the cutting member can be moved on one side to drive the rod to be pushed in and the inner end is cut into the corresponding recess of the ring to The azimuth rotation of the seat body is restricted to be positioned; and the cutting in the opposite direction drives the outer edge of the rod segment to exit the corresponding pocket of the ring, so that the seat body can perform the required azimuth rotation again.

Here, the present inventors have claimed that the application date of the invention of the above-mentioned application number: 101132908 "seat rotation positioning structure" is taken as the domestic priority of the present case, and the seat rotation or positioning restriction group is further made again. The convenience is improved so that the user has better control in operation.

The invention is further improved according to the limited group which is arranged in the seat as the control azimuth rotation or positioning, so that the group which rotates or positions the control seat can be operated through a simpler operation. Expected seat is free to rotate, or the seat is presented The temporary setting where the orientation is limited.

The main object of the present invention is to include a sleeve for rotating or temporarily positioning the control seat: a sleeve is sleeved on the upper portion of the gas pressure bar, and an upper portion of the sleeve is formed Intercepting space, in order to accommodate the outer ring to form a plurality of pockets, and the opening along the upper end of the sleeve is suitable for tightly covering a top cover to apply the ring ring to the orientation limit; One end of the sleeve facing outward is a pipe section extending at a predetermined end portion to form at least one or more convex portions, so as to fit in an outwardly-facing end combined with a spring-loaded rod segment, and at least one or more recesses are provided at one end of the action. The abutting member of the notch fits into a preset shape recess inside the triggering member, and the notch at one end of the abutting member received between the pulling member is cut into the convex portion of the section of the sleeve corresponding to the sleeve, and then a screw is borrowed Introduced along a hole penetrating the outer side of the triggering member, and locked at one end of the rod portion of the spring sleeve; and the pulling member at one end of the limiting group body is not plucked, because the sleeve is penetrated The rod section inside the pipe section at one end of the cylinder is connected The orientation of the moving member resists, and one end of the rod segment is driven toward the corresponding recess of the inner ring of the sleeve to apply a temporary azimuth restriction to the seat; and when the trigger member is moved, the notch at one end of the abutting member can be used. In order to prevent the convex portion of the tube segment at one end of the sleeve from rotating and displacement, the rod portion that is locked by the screw at one end of the trigger member is displaced outward, and the spring sleeved on the rod segment is pressed and the rod is driven. One end of the segment is separated from the corresponding recess of the ring, so that the seat is free to rotate according to the required orientation.

The second object of the present invention is to form a circular recessed space on the inner end of the pulling member which is inserted into the abutting member at one end of the action, so as to engage a circular space, and the other is The corresponding end of the abutting member incorporated in the inner part of the triggering member is a symmetrical outer inclined layer which is abutting as the abutting member is completely abutted when the inside of the triggering member is not dialed, and is toggled on the pulling member. The trigger member can be ejected outwards by the outer inclined layer of the abutment.

A third object of the present invention is to form a polygonal layer on the inner circumference of the ring placed in the upper portion of the sleeve, and to set the corresponding polygonal peripheral group corresponding to the upper portion of the gas pressure bar.

A fourth object of the present invention is to form a section plane at the outer end of the rod section accommodated inside the pipe section at one end of the sleeve, so as to correspond to the preset part of the outer portion of the trigger member with the abutting member interposed therebetween Set the area for exact arrival, and match the rotation of a screw.

The seat rotation positioning structure designed by the present invention (such as the first to third figures) is a restriction group 8 for rotating or temporarily positioning the control seat: the upper section of the gas pressure bar 1 is sleeved The sleeve 2, and the upper portion of the sleeve 2 is formed with a space 21 so as to accommodate the ring 3 formed with a plurality of pockets 31 on the outer periphery (as shown in the sixth figure), and in the ring The inner periphery of the 3 is a polygonal layer 32, so as to be assembled with the matching polygonal periphery 11 of the upper portion of the gas pressure bar 1 (as shown in the fourth figure), and the opening along the upper end of the sleeve 2 is suitable for pressing and covering A top cover 4 is provided to limit the ring 3 to the orientation.

A pipe section 22 which forms at least one or more convex portions 23 at a predetermined end portion extending along one end of the sleeve 2 is formed to fit into the outer end and the rod portion 5 which is coupled with the spring 52. And four figures], and then the top part 6 which is recessed at one end or at least one notch 61 is inserted into a preset shape recess 71 inside the triggering member 7 (as shown in the seventh figure), and is accommodated in the wrench The end portion 6 of the abutting member 6 in the middle of the movable member 7 is cut into the convex portion 23 of the sleeve portion 22 corresponding to the sleeve 2 (as shown in Figs. 5 and 6), and then a screw 73 is attached to the outside of the trigger member 7 by a screw 73. The side through hole 72 is introduced and locked to one end of the rod segment 5 which is sleeved with a spring 52 on the outer circumference (such as the fourth and sixth figures); the inner portion of the trigger member 7 which is inserted into the abutting member 6 is recessed at the end of the action. The embossed pocket 71 is a section which is symmetrical outwardly inclined at the inner end to engage a circular space (such as the first and seventh figures), and the corresponding end of the abutting member 6 accommodated inside the urging member 7 It is a symmetrical outer inclined layer which is a matching abutting member 6 when it is placed in the trigger member 7 without being toggled. It can be completely abutted (as shown in the sixth figure), and when the triggering member 7 is moved, the triggering member 7 can be pushed out by the outer inclined layer of the abutting member 6 (as shown in the ninth figure); The rod section 5 inside the tube section 22 at one end of the cylinder 2 forms a section plane 51 at the outer end so as to correspond to the triggering member 7 in which the abutting member 6 is placed in the predetermined flat area 74 of the outer section.
