Definitions
- This invention pertains to a chair and desk system which is well suited for use in an educational environment.
- the system includes chairs, desks, chair/desk combinations and accessories for use therewith.
- Combination desk/chair units are typically employed in primary classrooms, and include a frame having a set of rear legs and a set of front legs.
- a seat is mounted to a seat support structure interconnected with the rear of the frame, and a desk is supported by a desk support structure located at the front of the frame.
- Tables typically consist of a rectangular laminated top with a leg supporting the top at each corner.
- Chairs are typically constructed of thick, hard plastic seats and backs which are mounted to a four-legged frame which includes a seat mounting area and a back mounting area.
- an article of furniture is made up of a supporting frame assembly and a furniture component mounted to the frame assembly.
- the frame assembly is substantially C-shaped when viewed from the side, and includes a pair of interconnected C-shaped side frame sections.
- Each side frame section includes a lower member which engages the floor or other supporting surface, an upright member extending upwardly from one end of the lower member, and an upper member which supports a component of the article of furniture.
- This construction of the frame assembly can be used to form a chair or a desk, and the open area of the frame assembly faces the area occupied by the user's legs. That is, the C-shaped frame assembly of the chair faces forwardly and the C-shaped frame assembly of a desk faces rearwardly, to maximize the amount of leg room available for a user.
- a chair constructed according to the invention has a seat supported by the upper members of the side frame sections.
- Each side frame section further includes an extension of the upright member which extends above the seat, and defines an area to which a back is mounted.
- the upper ends of the side frame sections are interconnected by an inverted U-shaped handle member, which is located behind the back.
- the side frame sections are constructed such that each lower member extends forwardly from the lower end of the upright member, such as at a bend located between the lower member and the upright member.
- a glide is mounted to each side frame section at the bend, and is adapted to engage the floor or other supporting surface at a location rearwardly of the user's center of gravity. In a preferred form, the glide engages the floor at a location rearwardly of the back. In this manner, the chair is resistant to tipping when the forward portion of the chair is raised.
- the back is designed such that its maximum width is at the upper end of the back, with the sides of the back being arcuate in shape and extending downwardly from the upper end of the back.
- the seat and the back define surfaces which support the user at an optimal seating angle and which provide comfort during long periods of setting.
- a desk top is mounted to the upper support members.
- the side frame sections are parallel to each other and extend in a vertical plane, and function to support the desk top above the floor or other supporting surface.
- Each side frame section includes a lower member which engages the floor and an upright extending upwardly therefrom, with the upper member extending from the upper end of the upright in a direction parallel to the lower member.
- the desk frame and top may have a construction suitable for a single student. Alternatively, the frame may be formed to have a greater length and to support a double desk top, to provide a double desk construction.
- the invention further contemplates a tablet desk in which an upright member extends upwardly from the forward end of one of the lower members.
- a tablet support frame is engaged with the upright member and is located over the seat, and a tablet top is mounted to the tablet frame so as to be spaced above and forwardly of the seat.
- the same basic construction of the chair frame assembly is employed to construct a tablet desk of this type.
- the invention further contemplates a double entry desk having a chair frame and a desk frame which are merged together, such that the lower member of each chair side frame section is formed continuously with the lower member of each desk side frame section.
- the desk top is permanently mounted in a fixed location above and forwardly of the seat, and the user can enter or exit the combination desk/chair assembly from either side.

- FIG. 1 illustrates a chair 50 constructed according to the invention.
- Chair 50 includes a frame assembly 52 to which a seat 54 and a back 56 are mounted.
- Chair 50 is well suited for use in an educational environment, although it is understood that chair 50 may be used in any satisfactory setting.
- frame assembly 52 is formed of a pair of side frame sections 58 , which are mirror images of each other.
- Each side frame section 58 defines a lower horizontal base section 60 and an upright 62 , between which a bend 64 is located.
- Upright 62 terminates in an upper end 66 .
- Base section 60 and upright 62 define an angle of approximately 88°, and upright 62 and upper end 66 define an angle of approximately 153°.
- Upper end 66 extends at an angle of approximately 105° relative to base section 60 .
- Each side frame section 58 is formed of a bent elliptical metal tubing material, although it is understood that other satisfactory materials and forming methods could be employed.
- Side frame sections 58 are oriented such that base sections 60 extend parallel to each other in a front-rear direction.
- Uprights 62 extend toward each other in an upward direction, defining an angle of approximately 42°.
- Each upright 62 includes a bend 70 toward its upper end, and bends 70 are oriented such that upper ends 66 of uprights 62 are parallel to each other when viewed from the front or rear.
- An inverted U-shaped handle member 72 is connected to upper end 66 of each side frame section 58 .
- handle member 72 defines an upper horizontal section 74 and a pair of depending side sections 76 .
- Each side frame section 58 is preferably formed of a tubular material defining an internal passage throughout its length, and a lower end of each handle side section 76 , which includes a series of ridges 77 , is received within the upwardly open internal passage defined by upper end 66 of each upright 62 .
- Handle member 72 functions to secure side frame sections 58 together at their upper ends and to span across the space therebetween.
- Each handle side section 76 is curved outwardly toward its upper end adjacent upper horizontal section 74 and curves inwardly at its lower end adjacent upper end 66 of one of uprights 62 .
- handle member 72 defines an open area 78 below upper horizontal section 74 and between side sections 76 , for providing a convenient and ergonomic hand grip area for use in lifting and moving chair 50 .
- a transverse cross-brace member 80 (FIGS. 1 - 3 ) extends between uprights 62 at the level of seat 54 and above base sections 60 .
- Cross-brace member 80 is secured at its ends to the inner facing surfaces of uprights 62 in any satisfactory manner, such as by welding.
- cross-brace member 80 functions to secure side frame sections 58 together into frame assembly 52 for chair 50 .
- a seat support member 82 extends forwardly from each side frame section 58 at a location below bend 70 .
- Each seat support member 82 extends forwardly from one of uprights 62 , in a direction parallel to the longitudinal axis of base section 60 .
- the forward end of each seat support member 82 terminates slightly rearwardly of the forward end of base section 60 .
- seat support members 82 are operable to mount seat 54 to frame assembly 52 .
- Seat support members 82 are preferably formed of the same material as side frame sections 58 , and are connected thereto in any satisfactory manner such as by welding.
- a rear glide 84 is mounted to each side frame section 58 at lower bend 64 .
- Each rear glide 84 defines a slot 86 which receives a tab 88 welded to side frame section 58 at bend 64 .
- An opening 89 is formed in the inner surface of glide 84 for receiving a screw 90 , which is engaged within one of threaded openings 91 formed in tab 88 .
- Glide 84 defines a lower engagement edge 92 which engages a supporting surface such as a floor, and a rear edge 94 extending upwardly from engagement edge 92 .
- An arcuate corner 96 is defined between engagement edge 92 and rear edge 94 .
- An upper, forward edge 98 of glide 84 defines a curved, contoured recess adapted to receive the outer, lower portion of side frame section 58 at lower bend 64 .
- Slot 86 which receives tab 88 , extends inwardly from the recess in upper, forward edge 98 .
- Rear glide 84 is configured and mounted to side frame section 58 such that engagement edge 92 is located at an elevation below the lower extent of base section 60 , to provide a space between the supporting surface and base 60 when chair 50 is supported on the supporting surface.
- Front glide 100 defines a lower engagement portion 104 and a ring 106 extending upwardly therefrom.
- End cap 102 defines an outer cap section 108 and an inner mounting section 110 provided with a series of ridges.
- Ring 106 of front glide 100 defines a passage 111 adapted to receive the end of base section 60 , with a shoulder located at the forward portion of ring 106 engaging the end of base section 60 .
- Mounting section 110 of end cap 102 is adapted to pass through the open area defined by ring 106 and into the open front end of base section 60 , for mounting both front glide 100 and end cap 102 to the forward end of base section 60 .
- Cap section 108 of end cap 102 is configured so as to engage ring 106 outwardly of the open area defined by ring 106 , which defines a recess R for receiving a peripheral outer flange F of cap section 108 which extends outwardly of mounting section 110 .
- Mounting section 110 is sized and configured so as to closely correspond to the shape of the internal passage defined by base section 60 , and the ridges of mounting section 110 provide a friction fit mounting of end cap 102 and front glide 100 to the forward end of base section 60 .
- Front glide 100 is preferably formed of a thermoplastic material such as Santoprene and end cap 102 is preferably formed of a nylon material, although it is understood that other satisfactory materials may be employed.
- An end cap 102 is engaged within the open front end of each seat support member 82 , without a glide such as 100 .
- Flange F is sized and shaped so as to correspond to the end of seat support member 82 . In this manner, end cap 102 functions to close the open forward end of each seat support member 82 and to provide a finished appearance.
- a mounting plate 112 is mounted between seat support members 82 toward the outer end of each mounting member 82 .
- mounting bosses 114 depend from the underside of seat 54 .
- a threaded fastener such as a screw 116 , extends through each of a series of openings 117 in mounting plate 112 and upwardly into a downwardly open internal passage 118 defined by each mounting boss 114 .
- seat 54 is mounted to seat support members 82 .
- seat 54 defines a downwardly facing rear surface 120 which is spaced slightly above the upper surfaces of seat support members 82 .
- the rear edge of seat 54 is spaced forwardly from the forward surfaces of side frame sections 58 .
- the front edge of seat 54 is located forwardly of the forward ends of seat support members 82 .
- Seat 54 is configured so as to define a rearwardly sloping upwardly facing support surface 126 having an angle of approximately 8° relative to horizontal, i.e. relative to the longitudinal axes of seat support members 82 and base sections 60 .
- the rearward slope of seat 54 functions to resist forward sliding of the user when seated in chair 50 .
- Seat 54 is nearly flat in a transverse direction, so as to allow a user to sit in various positions without pressure at the edges of seat 54 .
- the flatness of seat 54 accommodates off-center sitting and varying body shapes, and reduces pressure on softer body tissues which may otherwise cause circulatory discomfort.
- the forward portion of seat 54 shown at 128 (FIGS. 17, 18) slopes forwardly at an angle of approximately 5° relative to horizontal, commencing slightly rearwardly of the forward mounting bosses 114 .
- the front of seat 54 at front edge 124 defines a “waterfall”, providing easy ingress and egress to and from seat 54 .
- a pair of mounting bosses 132 extend rearwardly from the rear surface of back 56 .
- Each mounting boss 132 is located adjacent a mounting section of handle member 72 , shown at 134 , and is adapted to engage a forward area thereof.
- the rearwardly facing surface of each mounting boss 132 is configured so as to correspond to the external configuration of the forward area of mounting section 134 .
- Threaded fasteners, such as screws 136 extend through openings in each mounting section 134 and into one of a pair of passages 138 defined by mounting boss 132 .
- the passage in mounting section 134 defines a shoulder for engaging the head of screw 136 . With this arrangement, screws 136 are operable to engage mounting bosses 132 at each side of handle member 72 , for securely mounting seat 56 to and between handle member side sections 76 .
- Back 56 defines a lower edge 142 located above seat support members 82 and above the seat rear edge 122 .
- back 56 defines an upper edge 144 located above the upper end of handle member 72 .
- the upper area of back 56 which is engaged by a user's back, i.e. the area of back 56 located at and above the location of mounting bosses 132 , is oriented at an angle of approximately 15° relative to vertical in order to relieve muscular fatigue on the user.
- the rear portion of seat 54 and the upper portion of back 56 cooperate to define a sitting angle of approximately 97°.
- the 5° forward slope of the forward edge of seat 54 functions to define a trunk/thigh angle which approaches the optimum angle of 135°.
- This orientation of seat 54 and back 56 has been found to be ergonomically satisfactory and to provide a high degree of comfort for users when sitting for relatively long periods of time, such as can occur in an educational setting.
- Upper edge 144 of back 56 defines a slight upward curvature, and also defines the point of maximum width of back 56 .
- the sides of back 56 shown at 146 , are curved downwardly and inwardly, terminating at lower edge 142 .
- This shape of back 56 provides a high degree of support for the back of a user with a relatively small amount of material, by eliminating material laterally outwardly from the center of back 56 at the lower areas of back 56 .
- FIG. 19 illustrates chairs 50 , 50 ′, 50 ′′ and 50 ′′′ constructed according to the invention, and primed reference characters will be used to facilitate clarity.
- Chair 50 ′ includes a frame assembly 52 ′, and the remaining components of chair 50 ′ are identical to those shown and described with respect to chair 50 .
- Chair 50 ′ is adapted to accommodate a user smaller than the intended users of chair 50 .
- Seat support members 82 ′ of frame assembly 52 ′ are positioned at a lower elevation than in frame 52 , and the overall height of frame 52 ′ is less than that of frame 52 .
- the configuration of seat 54 and back 56 are the same for chair 50 ′ as chair 50 , as is the angular relationship between seat 54 and back 56 .
- the utilization of common components for chair 50 and chair 50 ′ provides economies in the manufacture of two different chair models intended for different groups of end users.
- Chair 50 ′′ includes a frame assembly 52 ′′ constructed generally similarly to frame assemblies 52 and 52 ′. Again, however, chair 50 ′′ is adapted for use with smaller individuals than chair 50 ′, and thus includes seat support members 82 ′′ located closer to base sections 60 ′′ and having a lesser height than frame assembly 52 ′.
- Chair 50 ′′ includes a seat 54 ′ and a back 56 ′, which are similar in shape to seat 54 and back 56 , respectively, but of a smaller scale for seating smaller users than are intended for chairs 50 and 50 ′.
- the configuration of seat 54 ′ and back 56 ′ is similar to that of seat 54 and back 56 , as are the angular relationships between seat 54 ′ and back 56 ′.
- handle member 72 , rear glides 84 , front glides 100 and end caps 102 are the same for chair 50 ′′ as for chairs 50 and 50 ′, thus providing an efficient and economical means for producing chairs of varying sizes with common components.
- Chair 50 ′′′ is adapted to accommodate even smaller individuals than chair 50 ′′.
- Chair 50 ′′′ includes a frame assembly 52 ′′′ which again has a similar overall configuration as frame assemblies 52 , 52 ′ and 52 ′′. Again, however, the seat support members 82 ′′′ are located at a lower elevation relative to base sections 60 ′′′. In addition, the overall height of frame assembly 52 ′′′ is less than that of frame assembly 52 ′′. With this arrangement, seat 54 ′′ is placed at a low elevation relative to the floor or other supporting surface, and back 56 ′′ is positioned so as to accommodate the back of such a user.
- seat 54 ′′ and back 56 ′′ each have a similar configuration as seats 54 , 54 ′ and back 56 , 56 ′, respectively, to provide the same ergonomic advantages as set forth above.
- the angular relationships between seat 54 ′′ and back 56 ′′ are also the same as described above with respect to seat 54 and back 56 .
- handle member 72 , rear glides 84 , front glides 100 and end caps 102 are the same components as shown and described previously, to provide efficiencies in the manufacture of chairs 50 , 50 ′, 50 ′′ and 50 ′′′.
- FIG. 19 illustrates chairs 50 , 50 ′, 50 ′′ and 50 ′′′ in a side-by-side manner, which well illustrates the difference in the chair sizes and the capability of chairs 50 - 50 ′′′ to handle differently sized individuals while utilizing a large number of common components for chairs of various sizes.
- FIG. 20 illustrates the operation of rear glides 84 in providing stability for a chair such as 50 .
- Rear glide 84 engages the floor or other supporting surface 150 , along with front glide 100 , to normally support chair 50 in use.
- Glides 84 , 100 are configured so as to space the base section 60 of frame assembly 52 above supporting surface 150 .

A back is mounted to the back support area. In another form, the furniture component is a desk or table top mounted to the furniture component support. Combination desk/chair units may also be constructed utilizing the same basic frame structure.
Description
- This application is based on and claims the benefit of provisional application Serial No. 60/160,348 filed Oct. 19, 1999.
- This invention pertains to a chair and desk system which is well suited for use in an educational environment. The system includes chairs, desks, chair/desk combinations and accessories for use therewith.
- Furniture used in educational settings, such as classrooms in primary and secondary schools, typically consists of combination desk/chair units or a series of tables in which students are seated in individual chairs. Combination desk/chair units are typically employed in primary classrooms, and include a frame having a set of rear legs and a set of front legs. A seat is mounted to a seat support structure interconnected with the rear of the frame, and a desk is supported by a desk support structure located at the front of the frame. This type of construction is old and well-known, and has been used in classrooms for many decades.
- Educational tables and chairs, which are used in other types of classrooms, are also typically constructed in a manner that is old and well-known. Tables typically consist of a rectangular laminated top with a leg supporting the top at each corner. Chairs are typically constructed of thick, hard plastic seats and backs which are mounted to a four-legged frame which includes a seat mounting area and a back mounting area.
- It is an object of the present invention to advance the design, function, manufacture and aesthetic characteristics of furniture which is typically employed in a classroom setting. It is a further object of the invention to provide such furniture which incorporates similar design elements for desks, chairs, chair/desk combinations and tables, which departs significantly from existing technology and which provides significant advantages in use, manufacture and aesthetics. A still further object of the invention is to provide such furniture which is readily adaptable for manufacture in varying sizes so as to accommodate differently sized users encountered in different educational settings. Yet another object of the invention is to provide such furniture which has ergonomic advantages over the prior art. A still further object of the invention is to provide such furniture which is relatively simple in its components and manufacture, and which utilizes a number of common components so as to reduce the cost of manufacturing furniture of varying sizes.
- In accordance with the invention, an article of furniture is made up of a supporting frame assembly and a furniture component mounted to the frame assembly. The frame assembly is substantially C-shaped when viewed from the side, and includes a pair of interconnected C-shaped side frame sections. Each side frame section includes a lower member which engages the floor or other supporting surface, an upright member extending upwardly from one end of the lower member, and an upper member which supports a component of the article of furniture. This construction of the frame assembly can be used to form a chair or a desk, and the open area of the frame assembly faces the area occupied by the user's legs. That is, the C-shaped frame assembly of the chair faces forwardly and the C-shaped frame assembly of a desk faces rearwardly, to maximize the amount of leg room available for a user.
- A chair constructed according to the invention has a seat supported by the upper members of the side frame sections. Each side frame section further includes an extension of the upright member which extends above the seat, and defines an area to which a back is mounted. In addition, the upper ends of the side frame sections are interconnected by an inverted U-shaped handle member, which is located behind the back.
- The side frame sections are constructed such that each lower member extends forwardly from the lower end of the upright member, such as at a bend located between the lower member and the upright member. A glide is mounted to each side frame section at the bend, and is adapted to engage the floor or other supporting surface at a location rearwardly of the user's center of gravity. In a preferred form, the glide engages the floor at a location rearwardly of the back. In this manner, the chair is resistant to tipping when the forward portion of the chair is raised.
- The back is designed such that its maximum width is at the upper end of the back, with the sides of the back being arcuate in shape and extending downwardly from the upper end of the back. The seat and the back define surfaces which support the user at an optimal seating angle and which provide comfort during long periods of setting.
- In a desk assembly, a desk top is mounted to the upper support members. The side frame sections are parallel to each other and extend in a vertical plane, and function to support the desk top above the floor or other supporting surface. Each side frame section includes a lower member which engages the floor and an upright extending upwardly therefrom, with the upper member extending from the upper end of the upright in a direction parallel to the lower member. The desk frame and top may have a construction suitable for a single student. Alternatively, the frame may be formed to have a greater length and to support a double desk top, to provide a double desk construction.
- The invention further contemplates a tablet desk in which an upright member extends upwardly from the forward end of one of the lower members. A tablet support frame is engaged with the upright member and is located over the seat, and a tablet top is mounted to the tablet frame so as to be spaced above and forwardly of the seat. The same basic construction of the chair frame assembly is employed to construct a tablet desk of this type.
- The invention further contemplates a double entry desk having a chair frame and a desk frame which are merged together, such that the lower member of each chair side frame section is formed continuously with the lower member of each desk side frame section. With this construction, the desk top is permanently mounted in a fixed location above and forwardly of the seat, and the user can enter or exit the combination desk/chair assembly from either side.

- FIG. 1 illustrates a
chair 50 constructed according to the invention.Chair 50 includes aframe assembly 52 to which aseat 54 and a back 56 are mounted.Chair 50 is well suited for use in an educational environment, although it is understood thatchair 50 may be used in any satisfactory setting. - Referring to FIG. 2,
frame assembly 52 is formed of a pair ofside frame sections 58, which are mirror images of each other. Eachside frame section 58 defines a lowerhorizontal base section 60 and anupright 62, between which abend 64 is located.Upright 62 terminates in anupper end 66.Base section 60 andupright 62 define an angle of approximately 88°, andupright 62 andupper end 66 define an angle of approximately 153°.Upper end 66 extends at an angle of approximately 105° relative tobase section 60. Eachside frame section 58 is formed of a bent elliptical metal tubing material, although it is understood that other satisfactory materials and forming methods could be employed. -
Side frame sections 58 are oriented such thatbase sections 60 extend parallel to each other in a front-rear direction.Uprights 62 extend toward each other in an upward direction, defining an angle of approximately 42°. Eachupright 62 includes abend 70 toward its upper end, and bends 70 are oriented such that upper ends 66 ofuprights 62 are parallel to each other when viewed from the front or rear. - An inverted
U-shaped handle member 72 is connected toupper end 66 of eachside frame section 58. Referring to FIGS. 3 and 5, handlemember 72 defines an upperhorizontal section 74 and a pair of dependingside sections 76. Eachside frame section 58 is preferably formed of a tubular material defining an internal passage throughout its length, and a lower end of eachhandle side section 76, which includes a series ofridges 77, is received within the upwardly open internal passage defined byupper end 66 of each upright 62.Handle member 72 functions to secureside frame sections 58 together at their upper ends and to span across the space therebetween. - Each
handle side section 76 is curved outwardly toward its upper end adjacent upperhorizontal section 74 and curves inwardly at its lower end adjacentupper end 66 of one of uprights 62. With this construction,handle member 72 defines anopen area 78 below upperhorizontal section 74 and betweenside sections 76, for providing a convenient and ergonomic hand grip area for use in lifting and movingchair 50. - A transverse cross-brace member80 (FIGS. 1-3) extends between
uprights 62 at the level ofseat 54 and abovebase sections 60.Cross-brace member 80 is secured at its ends to the inner facing surfaces ofuprights 62 in any satisfactory manner, such as by welding. In combination withhandle member 72,cross-brace member 80 functions to secureside frame sections 58 together intoframe assembly 52 forchair 50. - A
seat support member 82 extends forwardly from eachside frame section 58 at a location belowbend 70. Eachseat support member 82 extends forwardly from one ofuprights 62, in a direction parallel to the longitudinal axis ofbase section 60. The forward end of eachseat support member 82 terminates slightly rearwardly of the forward end ofbase section 60. In a manner to be explained,seat support members 82 are operable to mountseat 54 to frameassembly 52.Seat support members 82 are preferably formed of the same material asside frame sections 58, and are connected thereto in any satisfactory manner such as by welding. - Referring to FIGS. 1, 4 and7-11, a
rear glide 84 is mounted to eachside frame section 58 atlower bend 64. Eachrear glide 84 defines aslot 86 which receives atab 88 welded toside frame section 58 atbend 64. Anopening 89 is formed in the inner surface ofglide 84 for receiving ascrew 90, which is engaged within one of threadedopenings 91 formed intab 88. With this arrangement, glide 84 is easily mounted toside frame section 58, and easily removed when necessary for replacement. -
Glide 84 defines alower engagement edge 92 which engages a supporting surface such as a floor, and arear edge 94 extending upwardly fromengagement edge 92. Anarcuate corner 96 is defined betweenengagement edge 92 andrear edge 94. An upper, forward edge 98 ofglide 84 defines a curved, contoured recess adapted to receive the outer, lower portion ofside frame section 58 atlower bend 64.Slot 86, which receivestab 88, extends inwardly from the recess in upper,forward edge 98. -
Rear glide 84 is configured and mounted toside frame section 58 such thatengagement edge 92 is located at an elevation below the lower extent ofbase section 60, to provide a space between the supporting surface andbase 60 whenchair 50 is supported on the supporting surface. - Referring to FIGS. 1 and 12-14, a
front glide 100 and anend cap 102 are engaged with the forward end of eachbase section 60.Front glide 100 defines alower engagement portion 104 and aring 106 extending upwardly therefrom.End cap 102 defines anouter cap section 108 and aninner mounting section 110 provided with a series of ridges.Ring 106 offront glide 100 defines apassage 111 adapted to receive the end ofbase section 60, with a shoulder located at the forward portion ofring 106 engaging the end ofbase section 60. Mountingsection 110 ofend cap 102 is adapted to pass through the open area defined byring 106 and into the open front end ofbase section 60, for mounting bothfront glide 100 andend cap 102 to the forward end ofbase section 60.Cap section 108 ofend cap 102 is configured so as to engagering 106 outwardly of the open area defined byring 106, which defines a recess R for receiving a peripheral outer flange F ofcap section 108 which extends outwardly of mountingsection 110. Mountingsection 110 is sized and configured so as to closely correspond to the shape of the internal passage defined bybase section 60, and the ridges of mountingsection 110 provide a friction fit mounting ofend cap 102 andfront glide 100 to the forward end ofbase section 60. -
Front glide 100 is preferably formed of a thermoplastic material such as Santoprene andend cap 102 is preferably formed of a nylon material, although it is understood that other satisfactory materials may be employed. - An
end cap 102 is engaged within the open front end of eachseat support member 82, without a glide such as 100. Flange F is sized and shaped so as to correspond to the end ofseat support member 82. In this manner,end cap 102 functions to close the open forward end of eachseat support member 82 and to provide a finished appearance. - Referring to FIGS. 2 and 15, a mounting
plate 112 is mounted betweenseat support members 82 toward the outer end of each mountingmember 82. As shown in FIGS. 4 and 16, mountingbosses 114 depend from the underside ofseat 54. A threaded fastener, such as ascrew 116, extends through each of a series ofopenings 117 in mountingplate 112 and upwardly into a downwardly openinternal passage 118 defined by each mountingboss 114. With this arrangement,seat 54 is mounted toseat support members 82. Rearwardly of mountingbosses 114,seat 54 defines a downwardly facingrear surface 120 which is spaced slightly above the upper surfaces ofseat support members 82. - Referring to FIG. 4, the rear edge of
seat 54, shown at 122, is spaced forwardly from the forward surfaces ofside frame sections 58. The front edge ofseat 54, shown at 124, is located forwardly of the forward ends ofseat support members 82.Seat 54 is configured so as to define a rearwardly sloping upwardly facingsupport surface 126 having an angle of approximately 8° relative to horizontal, i.e. relative to the longitudinal axes ofseat support members 82 andbase sections 60. The rearward slope ofseat 54 functions to resist forward sliding of the user when seated inchair 50.Seat 54 is nearly flat in a transverse direction, so as to allow a user to sit in various positions without pressure at the edges ofseat 54. In addition, the flatness ofseat 54 accommodates off-center sitting and varying body shapes, and reduces pressure on softer body tissues which may otherwise cause circulatory discomfort. - The forward portion of
seat 54, shown at 128 (FIGS. 17, 18) slopes forwardly at an angle of approximately 5° relative to horizontal, commencing slightly rearwardly of theforward mounting bosses 114. The front ofseat 54 atfront edge 124 defines a “waterfall”, providing easy ingress and egress to and fromseat 54. - Referring to FIGS. 4, 5 and6, a pair of mounting
bosses 132 extend rearwardly from the rear surface ofback 56. Each mountingboss 132 is located adjacent a mounting section ofhandle member 72, shown at 134, and is adapted to engage a forward area thereof. The rearwardly facing surface of each mountingboss 132 is configured so as to correspond to the external configuration of the forward area of mountingsection 134. Threaded fasteners, such asscrews 136, extend through openings in each mountingsection 134 and into one of a pair ofpassages 138 defined by mountingboss 132. The passage in mountingsection 134 defines a shoulder for engaging the head ofscrew 136. With this arrangement, screws 136 are operable to engage mountingbosses 132 at each side ofhandle member 72, for securely mountingseat 56 to and between handlemember side sections 76. - Back56 defines a
lower edge 142 located aboveseat support members 82 and above the seatrear edge 122. In addition, back 56 defines anupper edge 144 located above the upper end ofhandle member 72. The upper area of back 56 which is engaged by a user's back, i.e. the area of back 56 located at and above the location of mountingbosses 132, is oriented at an angle of approximately 15° relative to vertical in order to relieve muscular fatigue on the user. - The rear portion of
seat 54 and the upper portion of back 56 cooperate to define a sitting angle of approximately 97°. In addition, the 5° forward slope of the forward edge ofseat 54 functions to define a trunk/thigh angle which approaches the optimum angle of 135°. This orientation ofseat 54 and back 56 has been found to be ergonomically satisfactory and to provide a high degree of comfort for users when sitting for relatively long periods of time, such as can occur in an educational setting. -
Upper edge 144 of back 56 defines a slight upward curvature, and also defines the point of maximum width ofback 56. The sides of back 56, shown at 146, are curved downwardly and inwardly, terminating atlower edge 142. This shape ofback 56 provides a high degree of support for the back of a user with a relatively small amount of material, by eliminating material laterally outwardly from the center of back 56 at the lower areas ofback 56. - FIG. 19 illustrates
chairs Chair 50′ includes aframe assembly 52′, and the remaining components ofchair 50′ are identical to those shown and described with respect tochair 50.Chair 50′ is adapted to accommodate a user smaller than the intended users ofchair 50.Seat support members 82′ offrame assembly 52′ are positioned at a lower elevation than inframe 52, and the overall height offrame 52′ is less than that offrame 52. The configuration ofseat 54 and back 56 are the same forchair 50′ aschair 50, as is the angular relationship betweenseat 54 and back 56. The utilization of common components forchair 50 andchair 50′ provides economies in the manufacture of two different chair models intended for different groups of end users. -
Chair 50″ includes aframe assembly 52″ constructed generally similarly to frameassemblies chair 50″ is adapted for use with smaller individuals thanchair 50′, and thus includesseat support members 82″ located closer tobase sections 60″ and having a lesser height thanframe assembly 52′.Chair 50″ includes aseat 54′ and a back 56′, which are similar in shape toseat 54 and back 56, respectively, but of a smaller scale for seating smaller users than are intended forchairs seat 54′ and back 56′ is similar to that ofseat 54 and back 56, as are the angular relationships betweenseat 54′ and back 56′. Again,handle member 72, rear glides 84, front glides 100 and endcaps 102 are the same forchair 50″ as forchairs -
Chair 50′″ is adapted to accommodate even smaller individuals thanchair 50″.Chair 50′″ includes aframe assembly 52′″ which again has a similar overall configuration asframe assemblies seat support members 82′″ are located at a lower elevation relative tobase sections 60′″. In addition, the overall height offrame assembly 52′″ is less than that offrame assembly 52″. With this arrangement,seat 54″ is placed at a low elevation relative to the floor or other supporting surface, and back 56″ is positioned so as to accommodate the back of such a user. Again,seat 54″ and back 56″ each have a similar configuration asseats seat 54″ and back 56″ are also the same as described above with respect toseat 54 and back 56. As before,handle member 72, rear glides 84, front glides 100 and endcaps 102 are the same components as shown and described previously, to provide efficiencies in the manufacture ofchairs - FIG. 19 illustrates
chairs - FIG. 20 illustrates the operation of
rear glides 84 in providing stability for a chair such as 50.Rear glide 84 engages the floor or other supportingsurface 150, along withfront glide 100, to normally supportchair 50 in use.Glides base section 60 offrame assembly 52 above supportingsurface 150. When the user leans back against back 56 and pushes upward on supportingsurface 150 torock chair 50, as shown in the right hand portion of FIG. 12,front glide 100 is lifted off supportingsurface 150.Rear glide 84 engages supportingsurface 150 at a location rearward of back 56 and therefore well rearward of the user's center of gravity during such normal rocking motion ofchair 50, to preventchair 50 from tipping over. The configuration ofrear glide 84 is such as to discourage backward rocking ofchair 50, in that point contact ofrear glide 84 with supportingsurface 150 is located at the most rearward possible location onchair 50. This ensures that the user's center of gravity is at all times located forwardly of the contact point betweenrear glide 84 and supportingsurface 150 during rearward rocking movement ofchair 50.Rear glide 84 is preferably formed of a rigid material such as glass filled nylon, although it is understood that other materials may be used. - While FIG. 20 illustrates operation of
glides 84 in connection withchair 50, it is understood that similar operation occurs with respect tochairs 50′, 50″ and 50′″ so as to prevent chair tipping during rocking movement of the chair. - FIGS. 21 and 22 illustrate a
desk 152 constructed according to the invention.Desk 152 includes aframe assembly 154 and a top 156, and is especially well suited for use with chairs such as 50, 50′, 50″ and 50′″ in an educational setting, although it is understood that the desk and chairs may be used in any setting as desired. - Referring to FIGS. 21, 22 and25,
frame assembly 154 consists of a pair of C-shapedside frame sections 158 in combination with across-brace member 160 extending therebetween. Eachside frame section 158 includes abase section 162, anupright section 164 and anupper section 166 to which top 156 is mounted, in a manner to be explained. Alower bend 168 is located betweenbase section 162 andupright section 164, and anupper bend 169 is located betweenupright section 164 andupper section 166. Eachside frame section 158 is preferably formed of a bent elliptical metal tubing material, although it is understood that other satisfactory materials and forming methods could be employed. - As shown in FIG. 22,
front glide 100 andend cap 102 are engaged with the open forward end of eachbase section 162, in the same manner as described above with respect to frameassembly 52 ofchair 50. Similarly, arear glide 84 is mounted to a mountingtab 88 secured to eachside frame section 158 atlower bend 168, in the same manner as described above with respect to frameassembly 52 andchair 50. In this manner, glides 84, 100 function to supportbase section 162 above the floor or other supporting surface, and prevent tipping ofdesk 152. -
Side frame sections 158 are spaced apart from each other and lie in parallel planes, and the space betweenside frame sections 158 is sufficient to accommodate a chair and a user.Cross-brace member 160 is preferably formed of the same tubular material as used to formside frame sections 158, and is connected toside frame sections 158 in any satisfactory manner, such as by welding. - Referring to FIG. 25,
frame assembly 154 further includes a pair ofparallel cross members 170 which extend betweenupper sections 166. Eachcross member 170 has a pair of spaced openings, and is connected at its ends toupper sections 166 in any satisfactory manner such as by welding. A pair ofrails 171 are mounted to crossmembers 170, extending in a front-rear direction perpendicularly to crossmembers 170 and parallel toupper sections 166. The function ofrails 171 will later be explained. -
Desk top 156 is preferably an injection molded plastic member, although it is understood that other satisfactory materials and forming methods may be employed.Desk top 156 defines atop wall 172, depending front andrear lips side lips 178 extending between front andrear lips - As shown in FIGS.22-24 and 28-30, a series of mounting
bosses 182 depend fromupper wall 172 ofdesk top 156, and each defines a passage adapted to receive a threaded fastener such as ascrew 184 which extends through an opening in one ofcross members 170 into engagement with a passage in one of mountingbosses 182, so as to securedesk top 156 to frameassembly 154. - A pair of
pencil troughs 186 are formed intop wall 172 at its side edges. In addition, a series of reinforcing ribs 188 (FIGS. 28-30) are formed integrally withdesk top 156 for adding rigidity totop wall 172. - FIG. 31 illustrates an
alternative desk top 156′, which is generally similar in construction todesk top 156 as illustrated in FIGS. 21-28.Desk top 156′ includes a recessedtop wall 190, which is adapted to receive aninsert 192, illustrated in FIG. 20. The recess oftop wall 190 is shallow and flat, and is defined by inner edges of front, rear andside lips Insert 192 is placed within the recess and is secured in position in any satisfactory manner, such as by use of an adhesive.Insert 192 provides a hard, smooth surface suitable for writing and for withstanding scratches, bumps and other forces to which the upper surface ofdesk top 156′ is subjected during use. In addition,insert 190 provides the capability of applying a logo, guidelines, lettering or numbering to the upper surface ofdesk top 156′ by application to insert 192, in a manner as is known. - FIG. 33 illustrates
desk 152, along withdesks 152′, 152″ and 152′″, which have the same general construction asdesk 152. As can be seen, however,desks 152′, 152″ and 152′″ increase in height relative todesk 152 and relative to each other, for accommodating different chair heights and sizes of users.Desks same desk top 156 asdesk 152, and each includes a frame assembly having an increasing height for locating top 156 at increasingly higher elevations above the supportingsurface 150. Each frame assembly, shown at 154′, 154″ and 154′″ fordesks 152′, 152″ and 152′″, respectively, has a pair of side frame sections with base sections and upper sections configured similarly tobase section 162 andupper section 166 offrame assembly 154, and the height of the upright section of each such side frame section varies to provide the desired height ofdesk top 156 above the supporting surface, shown at 150. With this arrangement, it can be appreciated that a variety of desk heights can be provided utilizing asingle desk top 156 while only slightly varying the construction and configuration of the desk frame assembly, according to the targeted end users of the desk. - FIGS.34-42 illustrate a
double desk 194 constructed according to the invention.Double desk 194 includes aframe assembly 196 and atop assembly 198, and is adapted for use with a pair of chairs. - Referring to FIG. 36,
