DETAILED DESCRIPTION

[0020] Turning now to the drawing figures, an exemplary reformer apparatus 100 in accordance with the present disclosure is shown in perspective views in FIGS. 1 and 2. The apparatus 100 includes a generally rectangular frame 102 that has a pair of parallel side rail members 104, a head end member 106, and a foot member 108 spacing the side rail members 104 apart. Each end of the side rail members 104 is joined to one of a head or foot member 106, 108 by a corner member 110. Each side rail member 104 includes a horizontally extending longitudinal flange 111 forming a track upon which a carriage 112 is mounted for back and forth movement between the head end member 106 and the foot end member 108. The carriage 112 is resiliently biased toward the foot end member 108 by one or more springs 114 connected to an anchor bar 116 fastened to the frame 102 adjacent the foot end member 108.

[0021] The carriage 112 has a set of four roller wheels 118 supporting the carriage 112 on the flange 111 of each side member 104 and four side guide rollers 120 (see FIG. 6) for maintaining the carriage 112 in proper alignment between the side members 104 during use. As shown in FIG. 6, each end of the anchor bar 116 is supported in one of a plurality of slots 124 in a bracket 122 fastened to one of the side members 104. The other end of each of the springs 114 is fastened to an underside of the carriage 112. Referring back to FIGS. 1 and 2, the reformer exercise apparatus 100 includes an adjustable foot bar 126 adjacent the foot end member 108. The carriage 112 has a pair of spaced apart shoulder stops 128 and a headrest 130 therebetween. A user can sit or recline on the carriage 112 and push his or her feet against the foot bar 126 to move the carriage 112 away from the foot end of the reformer apparatus 100. Alternatively, the user may pull arm cords (not shown) that run from the carriage 112 through pulleys 132 to hand grips (not shown) to also move the carriage 112 away from the foot end member 108 during exercise.

[0022] Turning now to FIGS. 3 and 4, FIG. 3 is an exploded view of one of the corner members 110 showing features of the extrusion side rail member 104, one of the end members 106, 108, and the internal connection components of the corner member 110. Each corner member 110 joins one of a head or foot end member 106 or 108 to one of the side rail members 104. FIG. 4 is an exploded view of the corner member 110 cover assembly components associated with each corner member 110.

[0023] Each side member 104 and each end member 106, 108 is a metal or rigid polymeric extrusion member 140 having, in cross section, an outer vertical wall 142, an inner vertical wall 144, a top wall 146 joining the outer vertical wall 142 to the inner vertical wall 144, and a bottom wall 148 joining the outer vertical wall 142 to the inner vertical wall 144. Each of the top wall 146, the bottom wall 148 and the inner vertical wall 144 has an interior projecting single screw race 150 formed therein. The outer vertical wall 142 has a pair of spaced apart interior projecting screw races 150 formed therein. The side members 104 each differs from the end members 106, 108 in that the side members 104 each have a longitudinally extending flange 111 projecting from the bottom wall 148 at a right angle to the inner vertical wall 144. This flange 111 serves as a track or rail supporting the roller wheels 118 of the carriage 112 described above.

[0024] As noted above, each of the inner vertical wall 144, the top wall 146 and bottom wall 148 of the extrusion members 140 has a single screw race 150 extending from the wall into the interior of the extrusion member 140 and extending lengthwise from the inside surface of the extrusion member 140. The outer vertical wall 142 of each extrusion member 140, however, has two equally spaced screw races 150 extending lengthwise from the inside surface of the extrusion into the interior space of the extrusion toward the screw race 150 projecting from the inner vertical wall 144. Each of the interior projecting screw races 150 in the outer wall 142 is preferably equidistant from the screw race 150 projecting from the inner vertical wall 144.

[0025] There are preferably three threaded studs 152 installed in three of the five races 150 in each of the members 104, 106 and 108. In particular, the outer vertical wall 142 carries two studs in its two spaced races 150 and one stud 152 in the race 150 extending from the inner wall 144. The end member 106, 108 carries one threaded stud in each of the races 150 in the top wall 146 and the bottom wall 148, and preferably one threaded stud 152 in either the upper or lower race 150 in the outer wall 142 of the end member 106 or 108 to which the side rail member 104 is to be connected.

[0026] Each corner member 110 includes a rigid elongated angle extrusion member 160 having an L shape cross section with a first leg 162 and a second leg 164 extending at a right angle from the first leg 162. The elongated angle member 160 has an upper end 166 and a bottom or lower end 168 and has a longitudinal boss 170 extending lengthwise adjacent the distal end or side of each leg 162 and 164. This boss 170 forms a longitudinal groove 172 for receiving a cover 180 described more fully below.

[0027] The upper end 166 of the angle extrusion member 160 has a set of five spaced apertures or apertures 174 through each leg 162 and 164 located complementary to the screw races 150 in each of the side rail members 104 and end members 106, 108. When either a side rail member 104 or an end member 106 or 108 is positioned with its top wall 146 flush with the upper end 166 of the corner angle extrusion member 160 and against one of the legs 162, 164, these apertures 174 each align directly with one of the screw races 150 in that side rail member 104 or end member 106, 108. The three studs 152 project through corresponding three of these apertures 174. A suitable washer 176 and nut 178 are then installed on each of the studs 152 to fasten the member 104, 106, 108 to the leg 162 or 164 of the corner angle member 160.

[0028] The other of the side rail member 104 or end member 106, 108 is likewise fastened to the other leg 162 or 164 in a similar fashion. When all six studs 152 are fastened to the corner angle extrusion member 160, the assembled corner member 110 will look like that shown in FIG. 4. Upper portions of the boss 170 are preferably machined away adjacent the apertures 174 to permit access of a suitable wrench (not shown) to tighten each of the nuts 178 in place. Only three of the apertures 174 in each leg 162, 164 are utilized to fasten the rail or end member 104, 106 or 108 to the corner extrusion 160. Furthermore, a different set of three apertures 174 are used depending on which member, a side rail member or end member 106 or 108, is abutting the leg 162 or 164 of the corner extrusion member 160. This particular arrangement permits wrench access to each of the studs 152 and nuts 178 with sufficient clearance for tightening of the nuts without interference with an adjacent nut.

[0029] An alternative assembly of the corner member 110 to that shown in FIG. 3 is shown exploded in FIG. 7. In this alternative each corner member 110 again includes a rigid elongated angle extrusion member 160 having an L shape cross section with a first leg 162 and a second leg 164 extending at a right angle from the first leg 162. The elongated angle member 160 has an upper end 166 and a bottom or lower end 168 and has a longitudinal boss 170 extending lengthwise adjacent the distal end or side of each leg 162 and 164. This boss 170 forms a longitudinal groove 172 for receiving the cover 180 described more fully below.

[0030] The upper end 166 of the angle extrusion member 160 has a set of five spaced holes or apertures 174 through each leg 162 and 164 located complementary to the screw races 150 in each of the side rail members 104 and end members 106, 108. In FIG. 7, the end member 106 or 108 has a stud 152 protruding from the top screw race 150. When the rail member 104 or an end member 106 or 108 is positioned with its top wall 146 flush with the upper end 166 of the corner angle extrusion member 160 and against one of the legs 162, 164, these apertures 174 each align directly with one of the screw races 150 in that side rail member 104 or end member 106, 108. One stud 152 projects through a corresponding top one of the apertures 174. A suitable washer 176 and nut 178 are then installed on the stud 152 to fasten the member 106, 108 to the leg 162 or 164 of the corner angle member 160. The angle extrusion member 160 has a plurality of press pins 151 pressed into the apertures 174 that will not be used for passage of fasteners, in this case, bolts 153 shown in FIG. 7, that extend into corresponding screw races 150 in the abutting side rail member 104 or end member 106, 108.

[0031] As shown in FIG. 7, there are three press pins 151 that align each of the leg 162 and 164 to the abutting member 104 or 106, 108. Each of these pins 151 is frictionally press fit into one of the apertures 174 as shown and has a protruding distal end which is sized to extend into one of the screw races 150. In particular, preferably the upper and lower screw races 150 in the side rail member 104 receive press pins 151 so as to align the remaining three screw races 150 in the inner and outer walls with the corresponding apertures 174 in leg 162 of the angle extrusion member 160. These three screw races each receive a bolt 153 that fastens the member 104 to the leg 162. The screw races 150 in the outer and inner walls 144 and 142 of the end member 106, 108 similarly align with and receive press pins 151 protruding outward from the apertures 174 in the other leg 164 of the angle extrusion member 160. These press pins 151 along with the stud 152 installed in the upper screw race 150 of the end member 106, 108 ensure precise alignment of the end member 106, 108 with the leg 164 of the angle extrusion member 160. Two bolts 153 pass through the remaining apertures 174 in the leg 164 into the aligned screw races 150. Thus the end member 106, 108 is fastened to the angle extrusion 160 via these two bolts 153 and the stud 152 via a nut 178 installed thereon.

[0032] When all six fasteners, either studs 152 with nuts 178 or bolts 153 are fastened to the corner angle extrusion member 160, the assembled corner member 110 will essentially look like that shown in FIG. 4. Upper portions of the boss 170 are preferably machined away adjacent the apertures 174 to permit access of a suitable wrench (not shown) to tighten each of the bolts 153 or nuts 178 in place. Only three of the apertures 174 in each leg 162, 164 are utilized to fasten the rail or end member 104, 106 or 108 to the corner extrusion 160. Preferably the other two apertures 174 in each leg 162, 164 receive press pins 151. Furthermore, different sets of three apertures 174 are used for fasteners depending on which member, a side rail member or end member 106 or 108, is abutting the leg 162 or 164 of the corner extrusion member 160. This particular arrangement permits wrench access to each of the studs 152 and nuts 178 or bolts 153 with sufficient clearance for tightening of the bolts or nuts without interference with an adjacent nut or bolt head.

[0033] Turning now to the exploded view in FIG. 4, the corner member 110 also includes an elongated cover 180, a top cover 182, and a bottom foot 184 that together hide the connections between the head and foot end member 106 or 108 and the side rail member 104 thereby presenting a smooth corner joint assembly to the frame 102.

[0034] The elongated cover 180 is preferably an elongated metal or polymer extrusion having an L shaped cross section and having a single longitudinal internal screw race 182 formed along the apex between the legs 184 and 186 of the extrusion. The outer edges of each leg 184 and 186 has a rib like boss 188 extending therealong that fits within the groove 172 along each leg 164 and 166 of the corner angle extrusion 160. To assemble to cover 180, one slides the extrusion 180 downward along the length of the corner extrusion 160 so that the rib like bosses 188 fully engage the grooves 172 until the cover 180 is fully seated down alongside the extrusion 160.

[0035] A foot pad 190 has a aperture therethrough that aligns with the screw race 182. A suitable screw is inserted through the aperture in the foot pad 190 and threaded into the race 182 to hold the cover 180 in place.

[0036] FIG. 5 shows an exploded view of the upper end of the cover 180 and underside of the top cap 192 separate from the corner angle extrusion 160. This top cap 192 has a smooth upper surface for joining or abutting against the upper sides 146 of the end member 106, 108 and rail member 104 joined as shown in FIG. 4. The underside of the top cap 192 has a tapered stub 194 projecting therefrom adjacent its outer corner spaced and aligned to frictionally fit within the screw race 182 in the cover 180. The underside of the top cap 192 also has two corner or L shaped bosses 196 projecting therefrom positioned to frictionally engage against the sides of the bosses 170 adjacent the upper end 166 of the extrusion 160 to firmly fasten the top cap 192 to the corner extrusion 160.

[0037] Together the cover 180, the foot 190 and the top cap 192, when installed on the corner angle extrusion 160, present a smooth corner 110 joining the side rail member 104 to one of the end members 106 or 108 such that the actual joint technique is hidden from view. To disassemble the corner member 110, the screw through the foot pad 190 is removed and the cover 180 pushed upward until the ribs 188 disengage from the grooves 172. The nuts 178 may then be accessed for disassembly from the studs 152 in a conventional manner.

[0038] Many changes may be made to the apparatus, which will become apparent to a reader of this disclosure. For example, the corner cover 180 and top cap 192 may be formed as a single member or may be permanently fastened together via cement or other permanent joint. The upper screw race 150 in the end member 106 may be utilized instead of the lower screw race 150 in the outer vertical wall 144 as shown in FIGS. 3 and 4. Although illustrated in FIG. 3, the side rail member 104 having studs 152 in the inner three races 150 in the outer and inner vertical walls 142 and 144 respectively, may be reversed with those of the end members 106 and 108 such that the combination is reversed, without the necessity of relocating the apertures 174. If the dimensions of the side rail member 104 and 106 and 108 are larger, then all five races 150 in each member may incorporate studs 152 provided sufficient space exists for engaging the adjacent nuts 178 in the assembled corner member 110.

[0039] Studs 152 and nuts 178 and/or bolts 153 may be interchangeably utilized in the embodiments set forth in this disclosure. Furthermore, the use of five apertures 174 and five races 150 is merely exemplary. A different number and orientation of these elements may be utilized. Therefore all such changes, alternatives and equivalents in accordance with the features and benefits described herein, are within the scope of the present disclosure. Any or all of such changes and alternatives may be introduced without departing from the spirit and broad scope of my disclosure and invention as defined by the claims below and their equivalents.
