Abstract
An adjusting assembly adopted for a seat of a chair comprises a support plate including a plurality of slots formed at four corners thereof respectively; two positioning members mounted on two sides of the top panel of the legs and each including a number of recesses arranged on one side thereof; two spacing members coupled with the positioning members and each including a plurality of guiding ribs fixed thereon; a plurality of engaging members, each including an actuating member fitted thereon, retained in a notch of the support plate and covered by a housing member, the engaging member further including at least one resilient element fitted on one side thereof, the actuating member including an extension disposed on end thereof, and one end of the actuating member which extends out of the housing member being limited in the support plate by ways of a locking member.
Description
- 1. Field of the Invention
- The present invention relates to an adjusting assembly adopted for a seat of a chair that can adjust the seat to a preferred position stably.
- 2. Description of the Prior
- Conventional chair includes a seat, a back, a plurality of legs, and two armrests, all of which allow to be adjusted. However, the seat of the chair can not be adjusted to slide along the support plate stably.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The primary object of the present invention is to provide an adjusting assembly adopted for a seat of a chair that can adjust the seat to a preferred position stably.
- An adjusting assembly adopted for a seat of a chair in accordance with a preferred embodiment of the present invention comprises:
- a support plate including a plurality of slots formed at four corners thereof;
- two positioning members mounted on two sides of the top panel of the legs and each including a number of recesses arranged on one side thereof;
- two spacing members coupled with the positioning members and each including a plurality of guiding ribs fixed thereon;
- the positioning members and the spacing members being axially connected to the slots of the support plate by using screwing elements with sleeves fitted thereon;
- a plurality of engaging members, each including an actuating member fitted thereon, retained in a notch of the support plate and covered by a housing member, the engaging member further including at least one resilient element fitted on one side thereof so as to bias against the housing member and push one end of the engaging member to retain in one of the recesses, the actuating member including an extension disposed on end thereof so that when a first driving stem of the actuating member is driven, the engaging member is controlled to engage to or disengage from the recess, and one end of the actuating member extending out of the housing member is limited in the support plate by ways of a locking member.
- Furthermore, a controlling line inserted through a second driving stem is used to control the engaging member to engage to or disengage from the recess as well.
-
FIG. 1 is a perspective view showing the exploded components of an adjusting assembly adopted for a seat of a chair in accordance with a preferred embodiment of the present invention; -
FIG. 2 is a perspective view showing the operation of the adjusting assembly adopted for the seat of the chair in accordance with the preferred embodiment of the present invention; -
FIG. 3 is a partial cross section view showing the operation of the adjusting assembly adopted for the seat of the chair in accordance with the preferred embodiment of the present invention; -
FIG. 4 is a perspective view showing a chair being adjusted to a predetermined position; -
FIG. 5 is another partial cross section view showing the operation of the adjusting assembly adopted for the seat of the chair in accordance with the preferred embodiment of the present invention; -
FIG. 6 is a perspective view showing a controlling line inserted through a second driving stem being used to control the engaging member; -
FIG. 7 is a perspective view showing the controlling line being used to position the seat and the support plate. - The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
- Referring to
FIG. 1 , anadjusting assembly 8 adopted for a set of a chair in according to a preferred embodiment of the present invention is connected with aseat 2 and disposed on atop panel 11 of a plurality oflegs 1 of the chair, wherein theadjusting assembly 8 comprises: - a
support plate 3 including a plurality ofslots 31 formed at four corners thereof respectively; - two positioning members 4 (as shown in
FIG. 1 ) mounted on two sides of thetop panel 11 of the legs 1 (as illustrated inFIG. 4 ) and each including a number ofrecesses 41 arranged on one side thereof; - two
spacing members 5 coupled with thepositioning members 4 and each including a plurality of guidingribs 51 fixed thereon (as shown inFIGS. 1 and 4 ); - the
positioning members 4 and thespacing members 5 being axially connected to theslots 31 of thesupport plate 3 by usingscrewing elements 32 with sleeves 33 (as illustrated inFIG. 4 ) fitted thereon; - a plurality of engaging
members 7, each including an actuating member 6 fitted thereon, retained in anotch 37 of thesupport plate 3 and covered by ahousing member 34, theengaging member 7 further including at least oneresilient element 71 fitted on one side thereof so as to bias against thehousing member 34 and push one end of theengaging member 7 to retain in one of the recesses 41 (as shown inFIG. 5 ), the actuating member 6 including anextension 61 disposed on end thereof (as illustrated inFIG. 1 ) so that as afirst driving stem 62 of the actuating member 6 is driven, theengaging member 7 is controlled to engage to or disengage from the recess 41 (as shown inFIGS. 1 , 3, and 5), and one end of the actuating member 6 extending out of thehousing member 34 is limited in thesupport plate 3 by ways of alocking member 35. - Each of the four corners of the
support plate 3 is fitted a washer 36 (as illustrated inFIGS. 1 and 2 ) so that theseat 2 is fixed on thesupport plate 3 stably. In operation, as shown inFIGS. 2 and 3 , thefirst driving stem 62 of theadjusting assembly 8 is pulled upward to actuate the actuating member 6 to rotate in the same direction, and theextension 61 of the actuating member 6 rotates to contact with thehousing member 34 so that theengaging member 7 is pushed outward by the resilient element 71 (as shown inFIG. 3 ) to disengage from therecess 41 of thepositioning member 4, hence thesupport plate 3 and theseat 2 allow to be adjusted forward and rearward. - After adjusting the
seat 2, thefirst driving stem 62 is released (as illustrated inFIGS. 4 and 5 ) so that the actuating member 6 returns to its original position and theextension 61 rotates downward (as shown inFIG. 5 ), such that theengaging member 7 engages to therecess 41 by using theresilient elements 71, positioning thesupport plate 3 and theseat 2. - Furthermore, in another operation of the
engaging member 7 as shown inFIGS. 6 and 7 , a controllingline 64 inserted through asecond driving stem 63 is used to control the engaging member 7 (as shown inFIG. 6 ) to engage to or disengage from the recess 41 (as illustrated inFIG. 6 ). - While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
