Definitions

  • Seating units such as office chairs may include armrests to support the forearms of a seated user.
  • armrests are often padded, and may include various positional adjustment features to accommodate the needs of a particular user.
  • adjustment features may include height adjustment, side-to-side adjustment, and/or front to rear adjustment.
  • Such adjustment may require that a user manipulate a release lever or the like to unlock the adjustment mechanism to permit movement of the armrest.
  • U.S. Patent No. 5,931,537 does disclose an adjustable armrest assembly including detent arrangement wherein an armrest will move from a normal use position to a retracted position when the chair is moved such as when the armrest engages a desk.
  • known adjustment mechanisms may be somewhat awkward or difficult to use, and may not permit a user to quickly and easily lock the armrest in the desired position.
  • the invention aims to alleviate at least to a certain extent the problems of the prior art.
  • One aspect of the present invention is an adjustable armrest for a chair including a base and a support member slidably coupled to the base for movement in first and second directions between first and second positions relative to the base, wherein the support member is biased into the first position.
  • the armrest includes a device selectively retaining the support member in the second position, and the device includes a catch and a removable retaining member that is engagable with the catch to retain the support member in the second position. The retaining member disengages from the catch upon movement of the support member to permit movement of the support member relative to the base.
  • a seating unit including a frame, a seat, and a pair of armrests movably mounted to the frame for movement between forward and rearward positions.
  • the armrests are biased into the forward position, and each armrest includes a device selectively retaining the armrest in the rearward position. Movement of the armrest releases the device such that the armrest moves to the forward position due to the bias.
  • a seating unit including a frame, a seat, a backrest, and a pair of armrests movably mounted to the frame for movement between forward and rearward positions.
  • the armrests are biased into the forward position, and a heart and pawl device operably interconnects the armrest with the frame.
  • the heart and pawl device selectively retains the armrest in the rearward position, and biases the armrest towards the forward position.
  • a seating unit such as a chair 1 for offices and the like includes a frame 2, a chair base 3 for supporting the chair on a floor surface, a seat 4, and a backrest 5.
  • the armrests 6 are connected to the frame by support members 7, and may be moved forwardly and rearwardly as indicated by the arrow "A" .
  • each armrest assembly 6 may include a support member 10 having a padded cushion 11 for supporting the forearm of a seated user.
  • An armrest base member such as slide block 12 is secured to the armrest support member 7 by screws 13, and is slidably received in a guide member 14.
  • the slide block 12 may be made of a relatively strong material, such as aluminum, and the guide member 14 may be made of a low-friction polymer or other suitable material.
  • the guide member 14 is generally C-shaped in cross section, and slide block 12 includes raised pads 15 at each corner having cylindrical surface portions that slidably engage the curved inner surface 16 of guide member 14.
  • a pin 17 extends through a keyhole shaped opening 18 in guide member 14, and into a slot or track 19 formed in slide block 12 to form what is sometimes referred to as a "push-push mechanism".
  • a push-push mechanism is a device that secures a useful component at one end of a stroke when pushed and released a first time, but then releases the component when pushed in the same direction and released a second time.
  • the track 19 includes an elongated linear portion 20, and a heart-shaped end portion 21.
  • the guide member 14 When assembled, the guide member 14 is positioned between tabs 22 and horizontal web 23 of support member 10.
  • Support member 10 is made of a sheet metal material, and tabs 22 are formed by making U-shaped cuts in vertical side web 10A of support member 10. Tabs 22 are then bent inwardly to form openings 22A.
  • a downwardly extending tab 24 of support member 10 extends through opening 25, and provides a stop for a spring 26.
  • Tab 24 is formed in a similar manner to tabs 22, and forms an opening 24A after tab 24 is bent downwardly.
  • spring 26 When assembled, spring 26 is positioned within channel 27 of slide block 12, with a first end 28 of spring 26 contacting an end 30 of channel 27, and a second end 29 of spring 26 contacts tab 24 of support member 10. Spring 26 is in compression to thereby bias the support member 10 in the forward direction as indicated by the arrow "F".
  • the lower end 31 of pin 17 When assembled, the lower end 31 of pin 17 is received in track 19, and shoulder 32 of pin 17 is sandwiched between the upper web 33 of guide member 14 and the upper surface 34 of slide block 12. Upper end 35 of pin 17 is slidably received in the elongated opening 18 in guide member 14.
  • the pin 17 will engage the elongated portion 20 of track 19. As the support member 10 is pushed rearwardly in the direction of the arrow "R" the pin 17 will travel along track 19 until it encounters the heart-shaped portion 21.
  • the pin 17 will travel as indicated by the arrows E and F and return to the elongated portion 20 of track 19, and the spring 26 will push the support member 10 back to the forward position.
  • the pin 17 may be biased by a spring or the like (not shown) in the direction of the arrow "G" to ensure that the pin 17 shifts into engagement with notch 39 when the force on the support member 10 is released immediately after the support 10 is pushed to the rearward most position wherein end 31 of pin 17 contacts sidewalls portions 37 and 38.
  • an armrest 50 includes a support member 51 that is similar to the support member 7 described above for connecting the armrest 50 to a seating unit such as the office chair 1 of Fig. 1 described in detail above.
  • a padded cushion 52 is secured to a structural member 53.
  • the structural member 53 has a shallow C-shape in cross section with a web 54, sidewalls 55, and lips 56 forming channels 57 that slidably receive extensions 58 of a slide block 59 that is secured to the support member 51.
  • a "heart and pawl" device 60 includes a rod 61 that is pivotably connected to a clevis 62 on structural member 53.
  • Heart and pawl device 60 is a commercially available prior art unit that is available from Lord Corporation, and includes an internal heart and pawl mechanism (not shown) and an internal spring (also not shown) biasing the rod 61 outwardly from the cylindrical section 65 of device 60 to thereby bias the structural member 53 and cushion 52 in the direction of the arrow "F".
  • Heart and pawl device 60 will latch to retain the cushion 52 and structural member 53 in the rearward position 66.
  • an armrest 70 includes a support structure 71 for connecting to a chair frame.
  • Support structure 71 includes a square boss 72 extending from an upper end 73 of the support structure.
  • the square boss 72 is slidably received in an elongated slot 75 in a slide member 74.
  • a fastener 76 extends through an opening 77 in a detent member 78 and into a threaded opening 79 on boss 72.
  • Retainer member 78 includes a cylindrical lower extension 80 that is received in an opening 81 in block 82.
  • a padded cushion 83 is secured to the slide member 74, and the block 82 is positioned within channel 84 of slide member 74.
  • An elongated flexible wire 85 has a curved end portion 86 that is rigidly fixed to the slide member 74 via a threaded fastener 87 and washer 88 that are received in a threaded opening 89.
  • Wire 85 includes a transversely (upwardly) extending end portion 90 that is received in track 91 of block 82.
  • Spring 92 includes a first end 93 that interconnects to a connector 94 on block 82 (see also Figs. 6 and 6A). When assembled, spring 92 is positioned within channel 95 of block 82, and a second end 96 of spring 92 is connected to a connector 97 on slide member 74. The spring 92 is tensioned to bias the slide member 74 and padded cushion 83 in the forward direction indicated by the arrow "F".
  • end 90 of wire 85 is received in track 91 of block 82 to form a heart and pawl device.
  • the end 90 of wire 85 will initially travel along the straight portion 98 of track 91 from the forward most position illustrated in Fig. 6. End 90 eventually contacts the heart-shaped raised portion 99, and travels along track section 100 until it contacts the corner 101. If the force on the slide member 74 is then released, the end 90 will contact extension 102 and member 74 will shift forward slightly in the direction of the arrow F, until the end 90 is positioned in corner 103 as illustrated in Fig. 6A.
  • slide member 74 If the force acting on slide member 74 is then released, slide member 74 will then slide forward in the direction of the arrow F, and end 90 of wire 85 will travel through the track portion 106 and through straight portion 98 of track 91 due to the bias of spring 92 until slide member 74 returns to the forward most position illustrated in Fig. 6.
  • an armrest including the present push-push mechanism may also include the adjustment features illustrated schematically in Figs. 6B, 6C and 6D. More specifically, the armrest 6 may be movable side-to-side relative to the support 7 as indicated by the arrow "S"; Fig. 6B.
  • the side-to-side adjustment mechanism may be a mechanism as illustrated in U.S. Patent Nos. 5,971,484 or 5,439,267, the entire contents of each of which are hereby incorporated by reference.
  • armrest 6 could rotate about a vertical axis 108 relative to support 7 as indicated by the arrow "Z"; Fig. 6C.
  • the mechanism for providing such rotation may be a mechanism as disclosed in U.S. Patent No. 5,971,484, the entire contents of which are hereby incorporated by reference.
  • armrest 6 may be vertically adjustable relative to support 7 as illustrated by the arrow "V"; Fig. 6D.
  • the mechanism for providing vertical adjustment may be the mechanism of the aforementioned U.S. Patent No. 5,971,484.
  • an armrest according to the present invention could have all of the adjustment features illustrated in Figs. 6B, 6C, 6D or any combination thereof. Alternately, the armrest could only have the fore-to-aft heart and pawl movement described in more detail above.
  • an armrest 110 includes a block 82, slide member 74, wire 85 and spring 92 that are substantially the same as discussed in more detail above in connection with Figs. 5-6A. Because this heart and pawl mechanism was described in detail above, it will not be further discussed in connection with the armrest of Figs. 7, 7A and 8.
  • the armrest 110 includes a height adjustment mechanism 111 that telescopically interconnects lower member 112 to upper member 113.
  • Mechanism 111 may be of the type discussed above in connection with Fig. 6D that is operated (released) by button 130.
  • the armrest 110 also includes rotational adjustment provided by detent member 78 and block 82.
  • detent members 135 are received in channels 137 of detent member 78, and are biased outwardly by springs 136.
  • Cylindrical extension 80 of detent member 78 is rotatably received in opening 81 in block 82.
  • Square opening 138 in detent member 78 engages square boss 139 of plate 114, such that detent member 78 does not rotate relative to the base 112.
  • detent members 135 are biased into engagement with notches 141 formed in arcuate detent sidewalls 140 of block 82.
  • Fig. 7A illustrates another version of the rotational adjustment mechanism.
  • the mechanism of Fig. 7A includes smooth sidewalls 140A, but includes detents 141A in the surface 82A of block 82.
  • Detent members are received in vertical channels (not shown) in detent member 78, and are biased downwardly by springs 136A to thereby provide rotational adjustment including detents to retain the armrest at a selected angular position.
  • the rotational adjustment may include smooth detent walls 140A in combination with the detent members 135 of Fig. 8 to thereby provide continuous rotational adjustment, without detents. If this arrangement is utilized, detent members 135 may be made of a relatively high friction material to engage the sidewall 14A and thereby retain the armrest in the selected angular position.
