DETAILED DESCRIPTION OF THE DRAWINGS
FIG. 1A shows a top, front, right perspective view of an apparatus 1 in accordance with an embodiment of the present invention. FIG. 2 shows a top, front, left perspective view of the apparatus 1 of FIG. 1A.
Referring to FIGS. 1A and 2, the apparatus 1 includes a left support 10, a right support 20, a device 30, a beam 50, device 60, a beam 70, cage stabilizing portion 80, inverted L-shaped members 90, 92, 94, and 96, brackets 100, 102, 104, and 106, and a bar, rod, or member 110.
Bench apparatus members 300 and 302 shown in FIG. 11, to be described later, can be rotated in the direction C1 about pivot pin 304. The bar, rod, or member 110 shown in FIG. 1A may be a chin up bar which can be held on by clips or nuts at its opposite ends in the configuration of FIG. 1A and which can be removed or detached from the members 14 and 24 and inserted into a side opening of the member 13 and an side opening of the member 23 so that the member 110 is held up by the combination of the members 13 and 23 (one at each end), and so that the member 110 is substantially parallel to the member or beam 70 and to the ground. With the member 110 in place, held up by the combination of members 13 and 23, the bench apparatus members 300 and 302 can be rotated back in the direction opposite to C1, until the ends of the members 300 and 302 opposite the pivot pin 304, rest on member or chin up bar 110. This allows for an inclined bench setup, i.e. the members 300 and 302 of the bench apparatus are held in an inclined position.
In at least one alternative embodiment the chin up bar or member 110 does not get attached with bolts or screws to members 13 and 23, rather bar or member 110 may be placed on so one of its ends rests on top of member 100b of the bracket 100 (or on an analogous member of bracket 102) and simultaneously the opposite end of the bar or member 110 rests and on top of member 104b of the bracket 104 (or analogous member of bracket 106), similar to the way the barbell 160 rests in FIG. 3, so that bar or member 110 is parallel to the member 70 (shown in FIG. 1A) and the ground. In at least one embodiment, the brackets 100, 102, 104, and 106 are bolted in place (brackets 100 and 102 on member 13 and brackets 104 and 106 on member 23) when the apparatus 1 is constructed. In at least one embodiment, at that time it will be determined how high they will want either the barbell 160 or the incline bar (the chinup bar or member 110) to sit, so that determines what level the brackets 100, 102, 104, and 106 will be attached, in at least one embodiment, i.e. typically the incline bar, chin up bar or member 110, determines what angle the members 300 and 302 (rotated in the C1 direction) (shown in FIG. 11), and the seat portion 308 (to which 300 and 302 are attached) will be placed at. Because the incline bar or chin up bar or member 110 just rests on two of the brackets, in at least one embodiment, such as 100 and 104, for example, the bar or member 110 can be put into place or taken away quickly. It makes it convenient between workout sets to change the member 110. There may be additional brackets, similar or identical to brackets 100, 102, 104, and 106 so that there are more levels to choose from for weight lifting exercises, such as many different incline heights to choose from.
The left support 10 includes members 11, 12, 13, 14, 14a, 14b, 15, 16, 17, and 18. Each of members 11, 12, 13, 14, 14a, 14b, 15, 16, 17, and 18 may be a hollow rectangular beam made substantially or entirely of a rigid strong metal, such as five gauge steel, in at least one embodiment. The members 11, 12, 13, 14, 14a, 14b, 15, 16, 17, and 18 may be integrated into one unit by welding, for example, so that for ease of assembly of apparatus 1, the left support 10 may be supplied as a single integrated unit. The member 13 has a plurality of front surface holes 13a and a plurality of side surface holes 13b. The member 23 has a plurality of front surface holes 23a and a plurality of side surface holes 23b (shown in FIG. 2).
The right support 20 includes members 21, 22, 23, 24, 24a, 24b, 25, 26, 27, and 28. Each of members 21, 22, 23, 24, 24a, 24b, 25, 26, 27, and 28 may be a hollow rectangular beam made substantially or entirely of a rigid strong metal, such as five gauge steel, in at least one embodiment. The members 21, 22, 23, 24, 24a, 24b, 25, 26, 27, and 28 may be integrated into one unit by welding, for example, so that for ease of assembly of apparatus 1, the right support 20 may be supplied as a single integrated unit.

The device 120 keeps the chain 122 from bunching up or tangling around the barbell 160, or snagging up on the barbell 160 (and/or the dumbbell 310 or 330, when the analogous or identical device is used on the dumbbell 310 or 330 shown in FIG. 15) when the U-shaped member 130, or the barbell 160 is lifted upwards in the direction U2 shown in FIG. 3. The use of device 120 also prevents or inhibits the chain 122 from going below the barbell 160 as the barbell 160 is lifted up in the direction U2, and this prevents or inhibits the chain 122 from adding to the weight of the barbell 160. I.e. when the barbell 160 is lifted upwards in the direction U2, if part of the chain 122 ended up vertically below the barbell 160, then a weightlifter would be lifting both the barbell 160 and part of the chain 122. The devices 140, 200, and 220 provide the same functions for their respective chains 142 (FIG. 3), 202 (FIGS. 4 and 5), and 222 (FIGS. 4 and 5), i.e. to keep their respective chains from tangling, bunching up or adding to the weight of the barbell 160. There are also analogous devices in FIG. 15 providing for the same function to keep the chains 320, 324, 340, and 344 from tangling, bunching up, or adding to the weight of the appropriate dumbbell (dumbbell 310 for chains 320 and 324, and dumbbell 330 for chains 340 and 344).
The inventor has determined that having two elastic cords 123a and 124a which are attached in the manner shown at one point from the same vertical height (i.e. spools 123 and 124 are at the same vertical height), but connected to points at two different vertical heights (i.e. spools 126 and 128 are connected at two different vertical heights) helps greatly to keep the chain 122 from tangling or bunching up and/or reduces the slack when someone lifts the barbell 160 (and thereby the U-shaped member 130) in the direction U2.
The spools 123, 124, 126, and 128 are fixed to the chain 122 by the devices 125 (for spools 123 and 124), 127 (for spool 126), and 129 (for spool 128) so that the spools 123, 124, 126, and 128 do not substantially change orientation or distance with respect to the particular chain link that they are attached to. The inventor has determined that this also helps to reduce slack, bunching up, or interference of the chain 122 while a person is lifting barbell 160 (and U-shaped bolt 130 in the direction U2 shown.

FIG. 10 shows a top, front, right perspective view of the apparatus 1 of FIG. 1A along with a first set of portions of a bench apparatus. As shown in FIG. 10, the bench apparatus may include a beam or member 260, which is shown parallel to the member 12 and 22 in FIG. 10, but whose angle with respect to members 12 and 22 can be changed as will be described. The bench apparatus may also include a rectangular tubes 266, 270, and 276 which are fixed to a top of the member 260. The bench apparatus may also include L brackets 268 and 272 which are fixed to the tube 270 and L brackets 274 and 278 which are fixed to the tube 276. The L-brackets 268, 272, 274, and 278 have slots 268a, 272a, 274a, and 278a into which screws can be inserted to attach a bench seat 298 shown in FIG. 11 to the member or beam 260. The member 260 is fixed perpendicularly or substantially perpendicularly to a member 286, by a tube 280 (in which an end of the member 260 resides) and by plates 282 and 284 which are fixed to the tube 280 and the member 260 by nut and bolt combinations. The plates 282 and 284 are also fixed to the member 286 by nut and bolt combinations.
A member 294 can slide within a hollow cavity of the member 286 in the directions D8 and D9 when not fixed with respect to the member 286. A pin 296 can be used to set the member 294 at a vertical position in the cavity of the member 286. Members 288 and 290 are fixed, such as by welding to the member 286, substantially perpendicularly or perpendicularly. The member 294 is fixed to the member 292 substantially perpendicularly or perpendicularly.
In at least one embodiment, the member 286 may be fixed to the plates 284 and 282 by a pin 284a and a rod 284b. In at least one embodiment, the pin 284a can be removed and the member 286 can rotate about the pivot point of the rod 284b in the direction C3 (shown in FIG. 11) to bring the member 286 inward against the member 260 (shown in FIG. 10) under the seat portion 298 (shown in FIG. 11). In at least one embodiment, the member 286 does not rotate outward from the position shown in FIG. 12 in the direction C4 and is prevented from doing so by a stop plate (not shown) fixed to one or more of the plates 282 and 284 and/or underneath the tube 280, shown in FIG. 10. Rotating the member 286 in the direction C3 shown in FIG. 11 makes the bench apparatus more compact and makes transport of the bench apparatus components (such as 260, 282. 284, 286, and other components shown by FIGS. 10-12, but not shown in FIG. 1A) easier and keeps the members 260, 286, and other bench apparatus members out of the way when the member 260 of the bench apparatus is lifted up and clockwise in the direction C1 shown in FIG. 10 to make room for squat exercises or other exercises.
FIG. 13A shows a top, front, right perspective view of the member 294 fixed to the member 292, such as by welding. FIG. 13B shows a top, rear, left perspective view of the member 294 fixed to the member 292 such as by welding. The member 294 includes a plurality of openings 294a through which the pin 296 can be inserted to set the member 294 at different vertical height positions within a cavity of the member 286, which allows and end 298a of the seat 298 to be tilted upwards with respect to the beam or member 70. The members 294 and 292 and any other members of the apparatus 1 or of the bench apparatus may be made of a hard rigid material such as five gauge steel, in at least one embodiment.
FIG. 11 shows a top, front, right perspective view of the apparatus 1 of FIG. 1A along with a second set of portions of the bench apparatus. FIG. 11 shows the seat 298 which may include a cushion 298b on top and a backing 298c which is fixed to the L brackets 268, 272, 274, and 276. FIG. 11 also shows incline beams or members 300 and 302 and member 306. The member 306 is fixed to the back of the backing 308 shown in FIG. 12. The member 306 sits on tube 262 when the seat back 308 is down. Members 300 and 302 are pivotally attached to the member 266 by a pivot pin 304 going through aligned openings in 300, 266 (opening 266a) shown in FIGS. 10, and 302. The members 300 and 302 can pivot about the pin 304 with respect to the member 266 which remains fixed to the member 260 shown in FIG. 10. Thus the members 300 and 302 (shown in FIG. 11) can be parallel to the member 260 (shown in FIG. 10) or can be pivoted in the direction C1 shown in FIG. 11, to make an angle with the member 260 for an inclined bench exercise. The members 300 and 302 have openings 300a and 302a shown in FIG. 11 through which the members 300 and 302 can be fixed to the seat back 308 (which is shown in FIG. 12). The seat back 308 has a cushion 308a and a backing 308b shown in FIG. 12, to which the members 300 and 302 can be fixed. The cushion 308a is attached to the backing 308b.
A pin 262a can be inserted through an opening in the tube 262 and through an opening in member 260, to prevent the member 260 from sliding within the tube member 262. When not locked into place with pin 262a , the function of 260 is to slide through 262 in either direction. This allows the weightlifter to adjust the length of the bench based on their body size or different kinds of workouts. Another use for shortening the length of the bench is for lifting it up out of the way so it clears the barbell 160 (pivotting in the direction C2 shown in FIG. 10) when the weightlifter is performing squats and other leg exercises. The member or beam 260 can be pivoted in the direction C2 (shown in FIG. 10) about a pivot pin that goes through opening 71a of L-shaped bracket 72 (shown in FIG. 1A), the opening 73a of L-shaped bracket 74 (shown in FIG. 2), and an opening in member 264 (shown in FIG. 10), wherein member 264 is between the L-shaped bracket 72 and 74.

The number “1” is shown upside down in FIG. 19, so that when attaching the appropriate chain link to hook 322 the number will be right side up. A link is skipped between numbers to allow for consistent orientation of a dumbbell such as 310 or barbell, such as 160, such links tend to orient themselves at angles, and it is better to skip a link. FIG. 19 shows upside down numbers “1”, “2”, “3”, and “4” and rightside up numbers “5”, “6”, “7”, “8”, “9”, “10”, “11” and “12”. In FIG. 19, the setting is “5” meaning that the chain link 321b has been placed on the hook 322 to set the height to a setting of “5”. In at least one embodiment, the numbering of the links of chain 320 and other chains mentioned in this application, ends prior to the start of devices for attaching the spools, such as device 347 for attaching spools 345 and 346 shown in FIG. 15. I.e. only alternate links above the spools would be numbered with numbered settings. In this way one can see the numbered settings on the chain, such as chain 320. Note that the chain 320, and other chains may be longer than shown and may have more settings, and an example was given for descriptive purposes.
