Referring to FIGS. 1a to 5b, a multifunctional sliding exercise machine 100 in accordance with an embodiment of the present disclosure includes a pair of bodies 110, a rotary shaft 130, and a pair of slide plates 140.
The pair of bodies 110 is formed in a symmetric shape and each of the pair of bodies 110 is hinge-coupled at one end thereof.
Each of the pair of bodies 110 includes a first frame 112 including a pair of connection brackets 112a at both ends thereof, a pair of rails 114 coupled at one ends thereof to one side of the first frame 112 so as to be spaced apart from each other by a predetermined distance, and a second frame 116 coupled to the other ends of the pair of the rails 114.
In addition, a pair of guides 118 is disposed at both sides of each of the pair of bodies 110 in such a manner as to be coupled at one ends thereof to a side of the first frame 112 and coupled at the other ends thereof to a side of the second frame 116.
The pair of guides 118 has an effect on the outer appearance of a product and plays an important role in rigidity of the entire structure. Thus, each of the guides 118 is preferably not formed in a linear shape, but is formed in a shape in which one or more inwardly convex sections and one or more outwardly convex sections are alternately arranged with each other along the lengthwise direction of the guides 118.
In this case, the pair of guides 118 includes a pair of extending sections 118a formed at one ends thereof, and a support shaft 118b is disposed between the pair of extending sections 118a in such a manner as to be penetratingly coupled at one end and the other end thereof to the extending extensions 118a. 
A pair of rotating rollers 119 is coupled to predetermined lengthwise positions of the support shaft 118b in such a manner as to be spaced apart from each other by a predetermined distance so that one side of each of the rotating rollers 119 abuts against each of the extending sections 118a. The pair of rotating rollers 119 serves as moving wheels when a user desires to move the multifunctional sliding exercise machine 100 to another place after using it.
A height adjustment support 120 is installed at the pair of extending sections 118a so as to adjust the height of the pair of bodies 110. The height adjustment support 120 includes a pair of holders 122 rotatably coupled to both ends of the support shaft 119b and a connection bar 124 configured to interconnect the pair of holders 122.
Herein, each of the pair of holders 122 is formed in an isosceles triangular shape, any one of three vertexes of each holder 122 is coupled to the support shaft 118b, and a rotating roller 126 is coupled to any one of the remaining two vertexes of each holder 122. In this case, the rotating roller 126 performs the same function as that of the rotating roller 119 coupled to the support shaft 118b. 
Further, the sides interconnecting three vertexes of each of the holders 122 are preferably formed in a curved shape. This is to prevent the sides of the holders 122 from colliding with each other to cause interference to occur when a user desires to store the pair of bodies 110 with them folded after the use of the multifunctional sliding exercise machine 100 and is to prevent the sides of the pair of holders 122 from abutting against the ground surface when the user desires to move the pair of bodies 110 to another place with them folded.
In addition, a pair of permanent magnets 115 for applying a magnetic force to each other is preferably disposed at predetermined lengthwise positions of one sides of the first frame 112 and the second frame 116 so as to confront each other. This is to maintain the pair of bodies in a state of being folded when the pair of bodies has been folded.
Meanwhile, a pair of elastic elements 117 each having a handle 117a formed at an end thereof is disposed at a pair of hinge units 113 to which the pair of bodies is hinge-coupled so that a user can do an exercise after sitting on a pair of slide plates 140 which will be described later and then gripping the handles 117a coupled to ends of a pair of elastic elements 117.
In this case, any material can be used as the elastic element 117 as long as it has elasticity, such as a rubber band, a spring or the like.
The rotary shaft 130 is rotatably coupled at one end and the other end thereof to the hinge units 113 to which the pair of bodies 110 is hinge-coupled so that the height of the hinge unit 113 can be adjusted.
In addition, when the user lifts the rotary shaft 130 with him or her gripping the rotary shaft 130, the pair of bodies 110 is folded.
The rotary shaft 130 includes a pair of support plates 132 eccentrically coupled to the pair of hinge units 113, respectively, and a connection plate 134 that interconnects the pair of support plates 132. The connection plate 134 is preferably formed in a shape in which both sides thereof are curved in a mutually symmetrical manner. This is to allow the user to easily grip the rotary shaft 130.
Here, a method for adjusting the height of the hinge units 113 hinge-coupled to the pair of bodies 110 is performed such that when the user rotates the connection plate 134 with him or her gripping it, the pair of support plates 132 eccentrically coupled to the pair of hinge units is rotated so that the height of the hinge units 113 is changed depending on a surface of the hinge units, which abuts against the ground surface.
In other words, the change of the height of the pair of bodies 110 makes different the inclined angle at which the pair of slide plates 140 slidably coupled to the pair of bodies 110 is slidably moved so that the exercise strength can be increased or decreased.
A pair of slide plates 140 is slidably coupled to the top surfaces of the pair of bodies 110 so that a user can do various exercises, i.e., abdominal extension, fly push up, lunge, squat, leg curl, and hip up using the pair of slide plates 140.
The pair of slide plates 140 includes a pair of movable members 142 slidably coupled to the pair of rails 114 and a plate 144 coupled to the top surfaces of the pair of movable members 142.
Herein, preferably, the plate 144 includes first and second handles 144a and 144b disposed at widthwise both sides thereof so as to be opposed to each other, and a plurality of incised grooves 146 formed at both sides of thereof, in which the first and second handles 144a and 144b are disposed, so as to allow the user to grip the first and second handles 144a and 144b. 
Further, the sliding distance of the pair of slid plates 140 is adjusted by a distance adjustment assembly 150 disposed at a predetermined lengthwise position of each of the pair of bodies 110. In other words, the user can adjust the sliding distance of the pair of slide plates 140 so as to fit his or her body.
The distance adjustment assembly 150 includes a stopper block 152 coupled at one end thereof to a predetermined position of one side of the first frame 112 and coupled at the other end thereof to a predetermined position of one side of the second frame 116, and a stopper 154 slidably coupled to any one of the pair of rails 114 so that the stopper 154 is inserted into any one of a plurality of stopper grooves 152a formed on the top surface of the stopper block 152 so as to be spaced apart from each other at predetermined intervals along the lengthwise direction of the stopper block to adjust the sliding distance of the slide plates 140.
In this case, the sliding distance of the slide plates can be adjusted by the collision the movable member 142 with the stopper 154 along the rail 114 with the stopper 154 and the movable member 142 confronting each other. The inventive multifunctional sliding exercise machine is preferably configured such that the user's body can be prevented from being injured by an impact due to the collision between the stopper 154 and the movable member 142.
To this end, the stopper 154 includes a seating protrusion 154a formed on a side surface thereof so as to confront the movable member 142, and the movable member 142 includes a seating hole 142a formed therein so as to confront the stopper 154 so that the seating protrusion 154a is inserted into the seating hole 142a and a retaining step 142b formed on the inner peripheral surface of the seating hole 142a so as to suppress an additional advance of the seating protrusion 154 inserted into the seating hole 142a. An elastic part such as a spring washer 154b or a rubber ring (not shown) is mounted around the seating protrusion 154a. By virtue of this configuration, an impact caused by the collision between the retaining step 142b and the seating protrusion 154a can be reduced.
Hereinafter, the operation of the multifunctional sliding exercise machine in accordance with an embodiment of the present disclosure as constructed above will be described.
First, a user puts the pair of bodies 110 on the ground surface with it unfolded, and then adjusts the sliding distance of the pair of slide plates 140 through the distance adjustment means 150 to fit his or her body, i.e., the lengths of two arms and two legs of the user.
Thereafter, the user can do various exercises such as abdominal extension, fly push up, lunge, squat, leg curl, and hip up as shown in FIGS. 5a and 5b after placing his both feet on the plate 144 of each of pair of the slide plates 140 or gripping the first and second handles 144a and 144b disposed at the plate 144 of each slide plate 140.
Subsequently, the user folds the pair of bodies 110 and then moves the multifunctional sliding exercise machine 100 to a place of storage after finishing the exercise.
Thus, the multifunctional sliding exercise machine in accordance with an embodiment of the present disclosure enables users to effectively perform a variety of exercises without constraints of place, time, and space so that they can perform an exercise on various muscular regions of their bodies.
In addition, the users can do a variety of exercises to fit their physical sizes and can easily store and carry the multifunctional sliding exercise machine.
While the present invention has been described in connection with the specific embodiments illustrated in the drawings, they are merely illustrative, and the invention is not limited to these embodiments. It is to be understood that various equivalent modifications and variations of the embodiments can be made by a person having an ordinary skill in the art without departing from the spirit and scope of the present invention. Therefore, the true technical scope of the present invention should not be defined by the above-mentioned embodiments but should be defined by the appended claims and equivalents thereof.
