Abstract
A lateral armrest support adjustment mechanism has a bracket attached underneath the chair with a slot receiving a lateral extension of the armrest support. A rack of teeth projecting into an opening extending along the lateral extension of the armrest support receives two pins depending from a knob carried on the bracket. A bar is biased into blocking relation with the teeth of the rack of teeth in order to latch the mechanism. When a user turns the knob, the pins walk along the teeth in order to laterally adjust the armrest support. The knob has four circumferentially equally spaced notches which facilitate ready gripping and turning by the user. The bracket has a square hole through one of its faces and a circular hole registered with the square hole through its opposite face. This allows the bracket to be utilized with another lateral adjustment mechanism. More particularly, a post with a square cross-sectional portion may be received through the further bracket openings and through a slot in an armrest support member. A knob may then be threaded to the post so that the knob extends through one of the bracket openings and pushes the armrest support extension against a face of the bracket thereby frictionally locking the armrest support to the bracket. Adjustment is accomplished by loosening the knob, moving the armrest support, and retightening the knob.

Background of the Invention 1. Field of the Invention This invention relates to a lateral adjustment 5 mechanism for a chair armrest.
2. Description of the Related Art Office chairs are typically adjustable so that they may accommodate a wide range of users. In this regard, one desirable adjustment is the width between the chair armrests. A known mechanism permitting such adjustment comprises a bracket mounted underneath the chair seat with a slot receiving a lateral extension of an armrest support member. A post extends through both openings in the bracket and a slot which runs along the lateral extension in the support. A large knob is threaded to 15 the post so that it abuts the support and pushes the support against the back of the bracket, thereby frictionally locking the support to the bracket. To laterally adjust the armrest, the knob is loosened, the armrest support pulled or pushed to an appropriate lateral position, and the knob then tightened to lock the support - and the armrest - in its new lateral position.
Because this mechanism relies on friction for locking, the knob must be made relatively large to allow the user a sufficient moment arm. Even so, two-handed operation of the knob is often required. In any event, adjustment while seated is difficult.
Furthermore, adjustment is a multi-step process: loosening the knob, moving the support, then tightening the knob.
There is therefore a need for a lateral adjustment mechanism which permits easy one-handed operation while seated.
There is also a need for a versatile apparatus adapted to permit construction of different adjustment mechanisms.
Summary of the Invention According to the present invention, there is provided a lateral adjustment mechanism for a chair armrest, comprising the following: an armrest support having an upstanding portion and a lateral extension, said lateral extension having an opening extending therealong and a rack of teeth extending therealong and projecting into said opening; a bracket adapted for mounting underneath a chair seat, said bracket having a slot slidably receiving said lateral extension of said armrest support; a bar within said armrest support opening biased into blocking relation with said teeth; a knob having a pair of depending pins extending through an aperture in said bracket and received within spaces between the teeth of said rack; whereby, when said knob is turned, said pins walk along said rack such that said armrest support moves with respect to said bracket.
According to another aspect of this invention, there is provided a bracket for a lateral adjustment mechanism for a chair armrest comprising the following: means for mounting said bracket underneath a chair seat; a slot for reception of a lateral extension of an armrest support, said armrest support of the type having an armrest support opening extending along said lateral extension; a first aperture extending through a face of said bracket to said bracket slot, said first aperture adapted for reception of walking pins whereby said bracket slot may receive an armrest support with a rack of teeth extending along said lateral extension and projecting into said armrest support opening, said rack of teeth for receiving said walking pins, and with a bar within said armrest support opening biased into blocking relation with said teeth; a second aperture extending through said face of said bracket, said aperture being non~
circular and adapted for reception of a post having a threaded end and a non-circular cross-section such that said post is held against rotation when within said aperture, whereby said bracket slot may receive an armrest support with an armrest support opening, said second aperture and said armrest support opening may receive said post, and a knob may be threaded onto said post into abutting relation with said armrest support in order to frictionally lock said armrest support between said knob and said bracket.

Detailed Description of the Preferred Embodiments Turning to Figure 1, a lateral adjustment mechanism illustrated generally at 10 comprises an armrest support 12 having an upstanding portion 14 and a lateral extension 16.
Referencing Figure 3 as well as Figure 1, the lateral extension has an opening 18 extending therealong and a rack of teeth 20 extending along, and projecting into, opening 18. A bracket 24 has a slot 30 which slidably receives the lateral extension 16 of armrest support 12. Bracket 24 has flanges 26 (Figure 1) with bolt receiving openings 28 (Figure 1) which adapt the bracket for mounting underneath a chair seat.
As best seen in Figure 3, a bar 34 within the armrest support opening 18 is biased by a spring 36, which acts between wall 38 of bracket 24 and the bar 34, into blocking relation with the rack of teeth 20.
A knob 40 has a pair of depending pins 42a, 42b extending through an aperture 44 in the bracket 24. The depending pins 42a, 42b are received within spaces 48 between the teeth 50 of the rack of teeth 20.
With reference to Figure 2, knob 40 has four circumferentially equally spaced finger receiving notches 52.
As will be apparent from that Figure, each of these notches is radiused.
5Returning to Figure 1, a back plate 56 is received by a recess 58 in bracket 24. Screws 60 received in shouldered openings 62 of the back plate and are threaded into threaded openings in pins 42a, 42b so that the back plate 56 holds the knob 40 in place.
10In operation, referencing Figure 2, a user sitting in a chair to which bracket 24 has been attached may reach under the chair seat and grasp knob 40. The four radiused notches 52 allow the knob to be grasped comfortably with little re-orientation of the user's natural hand position. The user may then turn the 15knob. Referring to Figure 4, if the knob is rotated in a clockwise sense, it rotates about pin 42a so that pin 42b leaves its space 48 between teeth 50 at one side of pin 42a.
Referencing Figure 5, pin 42b continues to move while the knob is rotated until pin 42b enters a space 50 which is at the 20opposite side of pin 42a. At this point the knob has rotated through 180 degrees. Clearly, the knob 40 may be turned clockwise or counterclockwise, as desired, and will alternately rotate about pins 42a and 42b as the knob is turned in one sense.
Consequently, pins 42a, 42b "walk" as the knob is rotated in one 25sense, therefore, these pins may be described as "walking pins".
Walls 17 and 19 limit rotation of the knob when one of the pins comes into abutment with one of these walls. Because knob 40 is laterally fixed with respect to bracket 24 and the bracket is fixed underneath a chair seat, it is the rack of teeth 20 which must move laterally when knob 40 is turned. However, the rack is fixed with respect to the armrest support 12.
Consequently, turning knob 40 moves the armrest support 12 laterally.
It will be noted from Figure 4 that bar 34 is displaced by a pin against the urging of spring 36 when the knob 40 is turned. The bar and spring therefore act to latch the lateral adjustment mechanism until knob 40 is turned.
As will be apparent to anyone who reaches under a chair while seated, the range of rotational motion of the hand allowed by human joints is limited. Furthermore, the torque which may be imparted is also more limited in this position. It will be apparent to those skilled in the art that the provision of the multi-notched knob 40 facilitates lateral adjustment of the armrest even given the limited rotational freedom of a user's hand. Furthermore, the torque required to turn knob 40 of adjustment mechanism 10 is sufficiently low that adjustment while seated is easily accomplished. This is in contrast to an adjustment mechanism relying upon a friction lock.
With reference to Figures 1 and 2, bracket 24 also has an opening 66 through its back face 68 and an opening 70 through its front face 72. Opening 66 has a square cross-section.
Opening 66 and 70 adapt bracket 20 for use with a second lateral adjustment mechanism as is described here following.
Turning to Figures 6 and 7, armrest support 112 of armrest adjustment mechanism 110 has an upstanding portion 114 and a lateral extension 116. The lateral extension has a slot 118 extending therealong. A post 180 extends through opening 66 of the back face 68 of bracket 24, slot 118 of armrest support 112, and opening 70 of the front face 72 of bracket 24. The post has a square cross-sectional portion 182 which is received within opening 66 in order to lock the post 180 against rotation. Post 180 also has a threaded end 184 for reception of knob 186. Knob 186 has a reduced diameter portion 188 which has a diameter less than that of opening 70 through the front face of bracket 24.
Accordingly, when knob 186 is threaded down on post 180, the 10reduced diameter portion 188 extends through opening 70 and abuts the lateral extension 116 of armrest support 112 on either side of slot 118. By tightening knob 186, the lateral extension 116 is therefore sandwiched between the knob and the inside back face of bracket 24 and frictionally locked in place.
15In operation, knob 186 may be loosened, the armrest support 112 moved laterally as desired and then knob 186 retightened. The lateral adjustment mechanism 110 is of simpler construction than that of mechanism 10 of Figure 1 so as to provide a less expensive option. It is not, however, preferred as one-handed operation while seated is not facilitated.
Nevertheless, bracket 24 may be used in either mechanism 10 of Figure 1 or mechanism 110 of Figure 6 which reduces overall manufacturing costs.
Bracket 24 and armrest support 12 (of Figure 1) and 112 (of Figure 6) are preferably made of glass reinforced nylon.
This is particularly useful in mechanism 110 of Figure 6 as glass reinforced nylon has a higher coefficient of friction than many other materials, such as steel, thereby enhancing frictional locking between the bracket and the armrest support.
Modifications with be apparent to those skilled in the art and, therefore, the invention is defined in the claims.
Because this mechanism relies on friction for locking, the knob must be made relatively large to allow the user a sufficient moment arm. Even so, two-handed operation of the knob is often required. In any event, adjustment while seated is difficult.
Furthermore, adjustment is a multi-step process: loosening the knob, moving the support, then tightening the knob.
There is therefore a need for a lateral adjustment mechanism which permits easy one-handed operation while seated.
There is also a need for a versatile apparatus adapted to permit construction of different adjustment mechanisms.
Summary of the Invention According to the present invention, there is provided a lateral adjustment mechanism for a chair armrest, comprising the following: an armrest support having an upstanding portion and a lateral extension, said lateral extension having an opening extending therealong and a rack of teeth extending therealong and projecting into said opening; a bracket adapted for mounting underneath a chair seat, said bracket having a slot slidably receiving said lateral extension of said armrest support; a bar within said armrest support opening biased into blocking relation with said teeth; a knob having a pair of depending pins extending through an aperture in said bracket and received within spaces between the teeth of said rack; whereby, when said knob is turned, said pins walk along said rack such that said armrest support moves with respect to said bracket.
According to another aspect of this invention, there is provided a bracket for a lateral adjustment mechanism for a chair armrest comprising the following: means for mounting said bracket underneath a chair seat; a slot for reception of a lateral extension of an armrest support, said armrest support of the type having an armrest support opening extending along said lateral extension; a first aperture extending through a face of said bracket to said bracket slot, said first aperture adapted for reception of walking pins whereby said bracket slot may receive an armrest support with a rack of teeth extending along said lateral extension and projecting into said armrest support opening, said rack of teeth for receiving said walking pins, and with a bar within said armrest support opening biased into blocking relation with said teeth; a second aperture extending through said face of said bracket, said aperture being non~
circular and adapted for reception of a post having a threaded end and a non-circular cross-section such that said post is held against rotation when within said aperture, whereby said bracket slot may receive an armrest support with an armrest support opening, said second aperture and said armrest support opening may receive said post, and a knob may be threaded onto said post into abutting relation with said armrest support in order to frictionally lock said armrest support between said knob and said bracket.

Detailed Description of the Preferred Embodiments Turning to Figure 1, a lateral adjustment mechanism illustrated generally at 10 comprises an armrest support 12 having an upstanding portion 14 and a lateral extension 16.
Referencing Figure 3 as well as Figure 1, the lateral extension has an opening 18 extending therealong and a rack of teeth 20 extending along, and projecting into, opening 18. A bracket 24 has a slot 30 which slidably receives the lateral extension 16 of armrest support 12. Bracket 24 has flanges 26 (Figure 1) with bolt receiving openings 28 (Figure 1) which adapt the bracket for mounting underneath a chair seat.
As best seen in Figure 3, a bar 34 within the armrest support opening 18 is biased by a spring 36, which acts between wall 38 of bracket 24 and the bar 34, into blocking relation with the rack of teeth 20.
A knob 40 has a pair of depending pins 42a, 42b extending through an aperture 44 in the bracket 24. The depending pins 42a, 42b are received within spaces 48 between the teeth 50 of the rack of teeth 20.
With reference to Figure 2, knob 40 has four circumferentially equally spaced finger receiving notches 52.
As will be apparent from that Figure, each of these notches is radiused.
5Returning to Figure 1, a back plate 56 is received by a recess 58 in bracket 24. Screws 60 received in shouldered openings 62 of the back plate and are threaded into threaded openings in pins 42a, 42b so that the back plate 56 holds the knob 40 in place.
10In operation, referencing Figure 2, a user sitting in a chair to which bracket 24 has been attached may reach under the chair seat and grasp knob 40. The four radiused notches 52 allow the knob to be grasped comfortably with little re-orientation of the user's natural hand position. The user may then turn the 15knob. Referring to Figure 4, if the knob is rotated in a clockwise sense, it rotates about pin 42a so that pin 42b leaves its space 48 between teeth 50 at one side of pin 42a.
Referencing Figure 5, pin 42b continues to move while the knob is rotated until pin 42b enters a space 50 which is at the 20opposite side of pin 42a. At this point the knob has rotated through 180 degrees. Clearly, the knob 40 may be turned clockwise or counterclockwise, as desired, and will alternately rotate about pins 42a and 42b as the knob is turned in one sense.
Consequently, pins 42a, 42b "walk" as the knob is rotated in one 25sense, therefore, these pins may be described as "walking pins".
Walls 17 and 19 limit rotation of the knob when one of the pins comes into abutment with one of these walls. Because knob 40 is laterally fixed with respect to bracket 24 and the bracket is fixed underneath a chair seat, it is the rack of teeth 20 which must move laterally when knob 40 is turned. However, the rack is fixed with respect to the armrest support 12.
Consequently, turning knob 40 moves the armrest support 12 laterally.
It will be noted from Figure 4 that bar 34 is displaced by a pin against the urging of spring 36 when the knob 40 is turned. The bar and spring therefore act to latch the lateral adjustment mechanism until knob 40 is turned.
As will be apparent to anyone who reaches under a chair while seated, the range of rotational motion of the hand allowed by human joints is limited. Furthermore, the torque which may be imparted is also more limited in this position. It will be apparent to those skilled in the art that the provision of the multi-notched knob 40 facilitates lateral adjustment of the armrest even given the limited rotational freedom of a user's hand. Furthermore, the torque required to turn knob 40 of adjustment mechanism 10 is sufficiently low that adjustment while seated is easily accomplished. This is in contrast to an adjustment mechanism relying upon a friction lock.
With reference to Figures 1 and 2, bracket 24 also has an opening 66 through its back face 68 and an opening 70 through its front face 72. Opening 66 has a square cross-section.
Opening 66 and 70 adapt bracket 20 for use with a second lateral adjustment mechanism as is described here following.
Turning to Figures 6 and 7, armrest support 112 of armrest adjustment mechanism 110 has an upstanding portion 114 and a lateral extension 116. The lateral extension has a slot 118 extending therealong. A post 180 extends through opening 66 of the back face 68 of bracket 24, slot 118 of armrest support 112, and opening 70 of the front face 72 of bracket 24. The post has a square cross-sectional portion 182 which is received within opening 66 in order to lock the post 180 against rotation. Post 180 also has a threaded end 184 for reception of knob 186. Knob 186 has a reduced diameter portion 188 which has a diameter less than that of opening 70 through the front face of bracket 24.
Accordingly, when knob 186 is threaded down on post 180, the 10reduced diameter portion 188 extends through opening 70 and abuts the lateral extension 116 of armrest support 112 on either side of slot 118. By tightening knob 186, the lateral extension 116 is therefore sandwiched between the knob and the inside back face of bracket 24 and frictionally locked in place.
15In operation, knob 186 may be loosened, the armrest support 112 moved laterally as desired and then knob 186 retightened. The lateral adjustment mechanism 110 is of simpler construction than that of mechanism 10 of Figure 1 so as to provide a less expensive option. It is not, however, preferred as one-handed operation while seated is not facilitated.
Nevertheless, bracket 24 may be used in either mechanism 10 of Figure 1 or mechanism 110 of Figure 6 which reduces overall manufacturing costs.
Bracket 24 and armrest support 12 (of Figure 1) and 112 (of Figure 6) are preferably made of glass reinforced nylon.
This is particularly useful in mechanism 110 of Figure 6 as glass reinforced nylon has a higher coefficient of friction than many other materials, such as steel, thereby enhancing frictional locking between the bracket and the armrest support.
Modifications with be apparent to those skilled in the art and, therefore, the invention is defined in the claims.
