- This invention relates to improvements to a bench, and more particularly to an adjustable bench which self-adjusts the gap between the bench seat pad and the back support pad to keep a minimal gap as the angle of the back rest is adjusted.
- A workout bench is a common exercise equipment for the users who work out in their homes or in club gyms. The workout bench is designed for the users to efficiently perform sit-ups, abdominal work, and upper body workout. A conventional type of bench comprises a body bench, and a foam-cushioned leg pad on a supporting frame that supports the body bench standing on the ground floor. The frame has limited adjustment for the angle of inclination of the back support with respect to the ground floor. This type of bench can be designed to be folded or compact for easier storage.
- In addition, an improved adjustable workout bench is provided in the current market, wherein the improved adjustable workout bench comprises a seat support, a back support, a pair of foam-cushioned leg pad, a supporting frame to support the seat support and the back support standing on the ground floor to form a predetermined angle of inclination with respect to the ground floor, and a back adjusting arrangement adapted to adjust the angle between the back support and the supporting frame. In other words, the angle between the back support and the supporting frame is adjustable to meet the user needs for a variety of exercises. However, this improved adjustable workout bench has a major drawback. The mechanism structure of the back-adjusting arrangement allows for a gap between the seat and the backrest. While the user is sitting or lying on the improved adjustable workout bench, the user's lower back is not supported due to the gap that is created between the backrest and the seat. Additionally, the structure of many benches creates a miss-match opening between the surfaces and creates a protrusion that passes through the gap that will dig into the user's back.
- What is needed is a bench with an adjustable seat and adjustable backrest that includes many angles and provides full lower back support by eliminating the gap between the backrest and the seat. The elimination of the gap between the seat and backrest also prevents pain due to the user encountering the bench frame. The disclosure found in this document provides the solution with an adjustable bench which self-adjusts the gap between the bench and the back support.
- It is an object of the adjustable bench to provide an adjustable bench which comprises an inclinable back support and a seat support which can adjust the distance between the seat and the back support as the angle of the back support is adjusted.
- It is another object of the adjustable bench to provide an adjustable bench, wherein the adjustable bench comprises a supporting frame having a first leg member and a second leg member adapted to support the back support and the seat support to securely standing on the ground floor.
- It is another object of the adjustable bench to provide an adjustable bench, wherein the adjustable bench comprises a back adjusting arrangement having a plurality of angle adjusting retainers arranged on the first leg member and an adjusting arm inclinedly arranged between the back support and the first leg member to securely lock on one of the angle adjusting retainers.
- It is another object of the adjustable bench to provide an adjustable backrest, wherein the adjusting arm comprises a pivot end pivotally connected on a predetermined position of a bottom face of the back support and a free end movably locked on the angle adjusting retainer to form an adjusting angle between the back support and the first leg member.
- It is another object of the adjustable bench to provide an adjustable seat, wherein the supporting frame comprises a seat adjusting arrangement having a common pivot end pivotally connected on the bottom front end of the back support adapted to activate transversal movement of the seat support.
- It is still another object of the adjustable bench to provide an adjustable bench, wherein no expensive and complicated structure is required to be employed in the present invention to achieve the above-mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution that allows the user easily adjust locations of the back support and the seat support to fit with different kinds of bodies of the users.
- According to the adjustable bench, the foregoing and other objects and advantages are attained by an adjusting bench, comprising: a back frame comprising a back support and a back adjusting arrangement to adjust the back support. A seat frame comprising a seat support and a seat adjusting arrangement to adjust a height of the seat support and a distance between the seat support and the back support. A supporting frame comprising a first leg frame and a second leg frame adapted to support the back support and the seat support securely standing on a ground floor.
- Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.

FIG. 1 shows a perspective view of a bench with a self-adjustinggap 10. Bench with a self-adjustinggap 10 is supported on afront support tube 20 and arear support tube 24. Each of thesetubes pads 19 that protect the support tubes from harming a floor and further reduce movement of the self-adjustinggap 10 on the ground. Afront leg 23 is connected between thefront support tube 20 and the main frame plate(s) 53, and therear leg 25 connects from thesupport tube 24 to the frame plate(s) 53. Therear leg 25 has a plurality ofstops 26 that provides stops for setting an angle for thetravel 99 of aback rest 70 relative to aseat 50. A pair ofguide tubes 28 keep thehandle 31 in proximity to the plurality ofstops 26. The stops 26 hold the backrest at 0, 20, 30, 45, 60, 85 degrees of rotation. While these rotation positions are identified, there can be more or less positions and degrees of rotation. - The
handle 31 is connected through abrace 30 to theback rest 70 with a pivoting connection that is visible in other figures. Theback rest 70 is shown in its range-of-motion travel 99. At the lowest position theback rest 70 sits on astop pad 27. At the other extreme oftravel 99 theback rest 70R is in an essentially vertical position. -
FIG. 2A shows a first bottom perspective of the bench with a self-adjustinggap 10 andFIG. 2B shows a second bottom perspective view of the bench with a self-adjustinggap 10. These two opposing underside views show a preferred embodiment that uses arack 77 and apinion 32 to move 96 or translate theback rest 70 as the angle of thebrace 30 is rotated relative to theback rest 70. The self-adjustinggap 10 is supported on thefront supporting tube 20 and therear supporting tube 24 onpads 19. Therear support tube 24 is shown with wheel(s) 21 that allows the self-adjustinggap 10 to more easily be moved. When the self-adjustinggap 10 is flat on the ground thewheels 21 are elevated. Therear leg 25 is shown connecting throughplates 53 to thefront leg 23. - The
handle 31 is constrained to move between therear leg 25 and theguide tube 28. As theback rest 70 is lifted, the angle of thebrace 30 relative to theback rest 70 changes throughpivot axis bolt 76. The frame/tube 71 pivots atpivot bolt 78 to change the angle of theback rest 70 relative to theseat 50. The angular change rotates thepinion 32 on therack 77 that forces theback rest 70 to move 96 or translate. Theback rest 70 has a plurality ofslide bolts 73 that travel inslots 72 in atube 71 that allows theback rest 70 to move relative to theseat 50. At the lowest rotation position of theback rest 70, the underside of theback rest 70 will rest against thestop pad 27. Theplates 53 support of theseat 50 including an angle of theseat 50 relative to therear leg 25 andplates 53. -
FIG. 3A shows a cross-sectional view of the bench with a self-adjustinggap 10 cut through the center of the bench with a self-adjustinggap 10 andFIG. 3B shows a bottom perspective view of the bench with a self-adjustinggap 10. Thehandle 31 is constrained to move between therear leg 25 and thebrace 30. The constraint causes the angle of the guide tube to change and forces thepinion 32 to drive therack 77. As theback rest 70 is lifted, the angle of thebrace 30 relative to theback rest 70 changes throughpivot axis bolt 76. The frame −tube 71 pivots atpivot bolt 78 to change the angle of theback rest 70 relative to theseat 50. The angular change rotates thepinion 32 on therack 77 that forces theback rest 70 to move 96 or translate. - The
back rest 70 has a plurality ofslide bolts 73 that travel inslots 72 in atube 71 that allows theback rest 70 to move relative to theseat 50. At the lowest rotation position of theback rest 70, the underside of theback rest 70 will rest against thestop pad 27. Therear leg 25 has a plurality ofstops 26 with astop tube 29 engaged on a stop. The stops 26 set an angle for the travel of aback rest 70 relative to aseat 50. A pair ofguide tubes 28 keep thehandle 31 in proximity to the plurality ofstops 26. A user can lift thehandle 31 and move the handle within the opening between theguide tube 28 and therear leg 25. Thehandle 31 controls the sequence of motion for theback rest 70 and thebrace 30. Images of the moved backrest relative to the frame are shown and described in the preceding figures. -
FIG. 4A shows a side sectional view of the bench with a self-adjustinggap 10 with the bench at a negative incline,FIG. 4B shows a side sectional view of the bench with a self-adjustinggap 10 with the bench set at neutral andFIG. 4C shows a side sectional view of the bench with the backrest set vertically. InFIG. 4A thetube 71 is shown sitting on thestop pad 27. With theback rest 70 in thenegative rotation 98 position thepinion 32 is at one extreme of therack 77, whereas isFIG. 4C with theback rest 70 inpositive rotation 97 thepinion 32 is at the other extreme position of therack 77. In these figures thegap 90 is essentially the same and prevents the cushions of thebackrest 70 from “crashing” into the seat or become deformed. When theseat 50 andbackrest 70 rub or crush together it can cause harm and requires pre-mature replacement of one or both cushions. -
FIG. 5A shows a perspective view of the bench with a self-adjustinggap 10 at a third embodiment andFIG. 5B shows another perspective view of the embodiment shown inFIG. 5A . These figures show another embodiment of akeeper 35 that maintains the position of thebrace 30 in relative position near therear leg 25. Thekeeper 35 hasside plates 34 or bars with akeeper tube 33 that essentially boxes the keeper around therear leg 25. As the angle of thetube 71 is moved, thetube 71 will pivot on thepivot bolt 78. This will change the angle of thebrace 30 relative to thetube 71 and thepinion 32 will rotate on thebolt 76 to move 96 or translate therack 77 and theback rest 70. Theback rest 70 has a plurality ofslide bolts 73 that travel inslots 72 in atube 71 that allows theback rest 70 to move relative to theseat 50. Theslide bolt 73 can have asleeve 74 to cushion theslide bolt 73 within theslot 72. Slide pads or glides 75 also cushions the underside of theback rest 70 on the tube(s) 71. -
FIG. 6 shows a perspective view of the bench with a self-adjusting gap at a third embodiment. This embodiment uses abelt 60 that is retained by aclamp 64 to the underside of thebackrest 70 at a mid-point and is clamped at the ends of the belt on to thebrace 30. This embodiment uses thekeeper tube 33 withside plates 34 to guide the guide tube, but other embodiments that were previously disclosed to guide thebrace 30 could be equally used. Instead of a rack and pinion, thestrap 60 is tracked around bearingtubes strap 60 is clamped onto the underside of thebackrest 70. As thebrace 30 pivots on theaxis bolt 76 thestrap 60 is placed into tension and will move 96 or translate the back rest on theframe tube 71. -
FIG. 7 shows a perspective view of the bench with a self-adjusting gap at a fourth embodiment. This embodiment uses astrap 60 that is retained to thebackrest 70. Theclamp 64 connects thestrap 60 to anelastic cord 65 and thebackrest 70. Theelastic cord 65 also connects to theframe tube 71 and maintains both tension of thestrap 60 and pulls thebackrest 70 away from theseat 50. The other end of thestrap 60 is secured with aclamp 61 onto thebrace 30. As thebrace 30 is rotated the strap wraps (or unwraps) around the bearingtube 63 to allow thebackrest 70 to move and maintain the gap between thebackrest 70 and theseat 50. -
FIG. 8A shows a perspective view of the bench with a self-adjusting gap at a fifth embodiment andFIG. 8B shows the fifth embodiment at adifferent backrest 70R rotational position. In this embodiment, thebackrest 70 pivots onpivot bolt 78 without thebackrest 70 translating. The gap is maintained by movement of theseat 50. Aplate 38 is secured to thebackrest 70 and rotates with thebackrest 70. Theplate 38 has acurved slot 45 and athird pivot 42 follows thecurved slot 45. Ashort arm 41 is connected at a first end to afirst pivot 40 and at a second end to asecond pivot 43. Theshort arm 41 constrains movement of along arm 44. Thelong arm 44 is connected at a first end to athird pivot 42 that tracks in thecurved slot 45 and at a second end to afourth pivot 46 that connects to abent arm 47. Thebent arm 47 pivots through afifth pivot 48 and is connected at a first end to thefourth pivot 46 and at a second end to aseat pivot 39 in aslot 49. Theslot 49 pushes and pulls on theseat pivot 39 pin on theseat 50 to push the seat forward or back. - Thus, specific embodiments of a bench with a self-adjusting gap have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
