[0002] A weight training bench is a chair used by users when performing weight training. It is called a bench bench because it is mostly used for training the supine bench press.

[0003] To accommodate different bench press postures, some bench press chairs are designed with adjustable backrest angles. However, the addition of these angle adjustment mechanisms affects the structural stability and ease of use of these bench press chairs, thus necessitating improvements. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide an adjustable slide rail bench press chair to solve the problems of the prior art.

[0005] The present invention provides an adjustable sliding rail bench press chair to solve the problems of known technologies. The chair includes: a support base comprising a pivot platform, a front inclined column extending forward and downward from the pivot platform, and a rear inclined column extending backward and downward from the pivot platform, such that the pivot platform is supported at a preset bench press height by the front and rear inclined columns; a seat cushion component disposed in front of the pivot platform, comprising a seat cushion portion and a seat cushion pivot portion located behind the seat cushion portion, the seat cushion pivot portion being pivotally connected to the pivot platform, allowing the seat cushion portion to pivot relative to the pivot platform within a seat cushion angle adjustment range to adjust the seat cushion placement angle; and a backrest component. A backrest component is disposed on the rear side of the pivot platform. The backrest component includes a backrest portion and a backrest pivot portion located on the front side of the backrest portion. The backrest pivot portion is pivotally connected to the pivot platform, allowing the backrest portion to pivot relative to the pivot platform within a backrest angle adjustment range to adjust the backrest angle of the backrest portion. A seat cushion angle positioning mechanism includes a pair of front inclined slide rails, a pair of front sliding sleeves, a front slider, a front connecting rod, and a front positioning member. The pair of front inclined slide rails are symmetrically arranged on the left and right sides of the front inclined column in a manner extending forward and downward along the front inclined column. The pair of front sliding sleeves are slidably fitted onto the pair of front inclined slide rails. The front slider is connected to the pair of front sliding sleeves. The sleeves are positioned between and correspondingly span the upper side of the front inclined column, sliding obliquely back and forth along the front inclined column. The two ends of the front connecting rod are pivotally connected to the front slider and the seat cushion component, respectively, so that the pivoting of the seat cushion and the oblique sliding of the front slider are interconnected via the front connecting rod. The front positioning member is disposed on the front slider and configured to adjustably fix the front slider to the selected seat cushion adjustment position on the front inclined column, thereby positioning the seat cushion at the corresponding seat cushion placement angle. A backrest angle positioning mechanism is also included, comprising a pair of rear inclined slide rails, a pair of rear sliding sleeves, a rear slider, a rear connecting rod, and a rear positioning member. The pair of rear inclined slide rails extend downwards and backwards along the rear inclined column. The extension is symmetrically arranged on the left and right sides of the rear inclined column. The pairs of rear sliding sleeves are slidably fitted onto the pairs of rear inclined slide rails. The rear slider is connected between the pairs of rear sliding sleeves and is correspondingly straddling the upper side of the rear inclined column, sliding obliquely back and forth along the rear inclined column. The two ends of the rear connecting rod are respectively pivotally connected to the rear slider and the backrest member, so that the pivoting of the backrest and the oblique sliding of the rear slider are interconnected through the rear connecting rod. The rear positioning member is disposed on the rear slider and configured to adjustably fix the rear slider to the backrest adjustment selection position on the rear inclined column, so that the backrest is positioned at the corresponding backrest placement angle.

[0006] In an embodiment of the present invention, an adjustable sliding rail type bench press chair is provided, wherein the support base further includes a standing device disposed at the rear end of the rear inclined column. The standing device includes a transverse support rod extending left and right from the rear end of the rear inclined column and a longitudinal support rod extending upward from the rear end of the rear inclined column.
