As outlined above, examples of the present technology relate to providing an adjustable bench having an adjustment assembly that includes one or more adjustment pins. The adjustable benches contemplated herein may be used for a variety of activities, such as athletic activities. The adjustable benches disclosed herein may be used as footrests, seats, and/or supports for prone positions. In some cases, the person using the adjustable bench may be generally parallel to, or tilted towards, the floor on which the adjustable bench rests. The swivel supports described below allow a variety of users to comfortably use the bench and can be adjusted to provide individual support and comfort according to the user's specific preferences or needs.

An adjustment assembly described herein may include one or more adjustment pins that engage an arcuate member of the bench to position one or more supports of the bench relative to the frame of the bench. In the protruded position, the adjusting pin allows the support to pivot in a single direction without actuating (eg pulling) the pin. Typically this single orientation coincides with the support structure being pivoted into a raised or elevated position. Thus, the user only needs to lift the support structure to adjust its position without retracting the pin. The structure of the adjustment pin allows the pin to engage the plurality of openings in the arcuate member as the support structure rises. Once the desired lifted position is reached, the bench can be used without further action on the user's part (eg a pin is already engaged with one of the openings to prevent reverse or downward swivel movement of the support structure). To lower the support structure, the user can retract and lower the adjusting pin. Also, if the adjusting pin is held in the retracted position, the support structure can pivot in any direction, like a conventional bench using the adjusting pin.

Another example of an adjustment system includes a striking plate comprising an angled spring pin (described briefly above and described in more detail herein) and a plurality of bent tabs secured to an arcuate member. Such an adjustment system may be incorporated into an adjustable bench that allows movement of the seat and/or rear pad in one direction without retracting the spring pins. There is no user interaction (eg retract or pull) with the spring pins required to move the seat and/or rear pad pad into a reclined position. The arcuate member may include a body and a striking plate fixed thereto. The body defines a slot into which the pin is to be inserted, allowing complete pin engagement. The slot has one flat face with two 90° edges and the pin contacts to engage the body. The opposite side of the opening may be defined by a curved or curved tab extending from the striking plate allowing easy release of the pin when the angled face of the pin contacts the tab. Bent tabs allow for smoother operation, and hole size uniformity eliminates the possibility of partial pin insertion and consequently reduces or eliminates the potential risk of damage.

It can be adjusted either by turning or turning. Additionally, spring 240 will be compressed when plunger 210 is moved to the retracted position.

7 shows a schematic diagram of another steering assembly of the adjustable bench of FIG. 1 in accordance with various examples of the present invention. The steering assembly shown in FIG. 7 is similar to that of FIG. 3 . Accordingly, not all elements shown in FIG. 7 are further described herein. Also, those skilled in the art will be able to relate the structure described in FIG. 3 to the structure shown in FIG. 7 . In FIG. 7 , striking plate 161 is attached to the outer surface of arcuate member 160 to provide a friction reducing surface between arcuate member 160 and angled face 214 of plunger 210 . In addition, the surface 166 of the striking plate 161 facing the angled face 214 is round, which prevents the striking plate ( 161) and the angled face 214 to reduce friction. In another example, surface 166 of striking plate 161 may be angled to reduce friction when in contact with angled surface 214 . The material of striking plate 161 may be selected to further reduce friction with angled face 214 . The rounded surface 166 of the striking plate 161 is configured to contact the angled face 214 of the plunger 210 when the angled face 214 is extended into the arcuate assembly opening 164 .
