Description

BACKGROUND

Adjustable benches, such as, for example, fitness benches, may have various designs including without limitation, fixed horizontal, fixed inclined, fixed decline, or with one or more adjustable portions. A common problem with fitness benches having adjustable portions is a noticeable gap between a movable seat back and a seat bottom when the seat back is in the inclined position. This gap can cause discomfort to a user while weight training or otherwise using the bench.

In addition, adjustable benches that are used with a weight rack often position a user away from the weight rack when the bench is adjusted. This can create a safety issue for the user.

Additional and/or alternate configurations of the channel may be used within the scope of this disclosure. The undersurface 134 of the seat bottom may provide a surface upon which at least a portion of the link 700 may support the seat bottom 130 from underneath and may slide against to allow for sliding contact between the seat back 120 and seat bottom 130, as will be described in more detail below.

The seat back 120 and seat bottom 130, as shown in FIG. 4, may be fabricated from compressible resilient material for the comfort of the user while lying on the adjustable fitness bench 100 and lifting weights. Such materials may include, for example, soft goods, foam, wood, gel, metal, plastic, padding or the like.

The shuttle 110, as shown in FIG. 6A, may include one or more bumpers 602 upon which a portion of the bar 320 may rest when the bench is placed in an incline position, such as, for example, that shown in FIGS. 2C and 5. The bumper 602 may be fabricated from natural rubber, Silicone rubber, Neoprene rubber, Butyl rubber, Ethylene Propylene Diene Monomer (EPDM) rubber, Nitrile butadiene rubber (NBR), foam, cork and/or the like.

In various embodiments, one or more bumpers may be positioned on a portion of the bar 320 as illustrated in FIG. 6B. When the bench is placed in an incline position, such as, for example, that shown in FIGS. 2C and 5, the bumper of the bar 320 may contact at least a portion of the shuttle 110.

FIG. 7A illustrates an isometric view of the link 700. The link 700 may extend from a portion of the seat back 120 and provide a sliding surface against which the undersurface 134 of the seat bottom 130 may rest. In an embodiment, the link 700 may include two parallel link hooks 720. Each of the link hooks 720 may extend away from and upward from a first end of the link towards a second end of the link. In various embodiments, a link may include a single link hook 720 or more than two link hooks.

In various embodiments, a link may include a link plate 710. A link plate may be a substantially flat surface that covers at least a portion of one or more of the link hook(s) 720. A link 700 may be connected to a seat back 120 via the link plate 710. A groove 722 along a first edge of each link hook 720 may provide a receptacle for the edge 712 of the link plate 710.

In an alternate embodiment, a link may not include a link plate as illustrated by FIG. 7B. In this embodiment, a link 700 may be connected to a seat back 120 via a surface 721 of one or more of the link hooks 720.

In various embodiments, a link 700 may include a link end 730. One of these embodiments is illustrated in FIG. 7A, which shows the link end 730 as a cylindrical bar fixed to an end of the link hooks 720. The link end 730 may include a solid core or it may be hollow. A curved groove 724 along a second edge of each link hook 720 may provide a receptacle for the link end 730. The curved surface 732 of the link end 730 may provide a sufficient sliding contact surface to support the undersurface 134 of the seat bottom 130. The curved surface 732 of the link end 730 may also have a low coefficient of friction to allow to provide a smooth surface for sliding contact.

In other embodiments, a link 700 may not include a link end. Rather, an end portion of one or more link hooks 720 may have a finished end portion 719 that may be configured to rest against and/or underneath a seat bottom 130, depending on the configuration of the bench, as illustrated by FIG. 7C. A link plate 710 may or may not be used with a link of this configuration. Although FIG. 7C illustrates a link 700 having a finished end portion 719 that is generally rounded, it is understood that different designs or configurations, such as for example, squared off, may be used within the scope of this disclosure.

In operation, the link 700 may allow the seat back 120 and seat bottom 130 to be connected with a sliding contact. This sliding contact allows the seat back 120 to rotate up and forward over the back edge of the seat bottom 130 when transitioning from the flat position to the incline position as shown in FIGS. 2B-2D and may reduce the size of the gap between the seat back 120 and the seat bottom 130 in the incline position.
