The angle adjustment bow-shaped member 130 is adjusted and fixed such that one end thereof passes through a first opening 116 provided in a front leg frame member 110 and either passes through or does not pass through a second opening 170 provided in a rear leg frame member 112 depending on the seating-surface seat angle, thereby creating a desired seating-surface seat angle between a floor surface and the lengthwise direction of a seating-surface seat 120.

Description

training bench

[0001] The present invention relates to a training bench that allows a user to train abdominal muscles, back muscles, and other muscles while sitting, lying face down, or lying on their back.

[0002] There is known a training bench that allows users to perform various types of training, mainly focusing on the upper body, while sitting on a bench consisting of a seat placed on a base placed on the floor and a back seat connected to the seat so that the inclination angle can be adjusted (for example, Patent Documents 1 and 2).

[0003] Utility Model Registration No. 3234794 Utility Model Registration No. 3232378

[0004] However, while conventional training benches allow the tilt angle of the back seat to be adjusted, they do not allow the tilt angle of the seat cushion to be adjusted, or even if it is, it can only be adjusted within a small range, which limits the freedom of training.

[0005] Therefore, an object of the present invention is to enable the inclination angle of the seat cushion as well as the back seat angle to be freely adjusted, thereby improving the degree of freedom in training.

[0006] One example of a training bench comprises a front leg frame member and a rear leg frame member, each of which can be placed in contact with the floor during training, and which are arranged side by side in a longitudinal direction such that both longitudinal directions are included in a single imaginary plane perpendicular to the floor, and which are connected at a connecting portion to form a predetermined angle within the plane; a seat support frame member and a back seat support frame member, which are arranged side by side in the longitudinal direction such that both longitudinal directions are included in the plane, and which have one end connected to the connecting portion so that they can rotate within the plane around the connecting portion, and which have a first opening and a second opening; a seat and a back seat, which are arranged side by side in the longitudinal direction such that both longitudinal directions are included in the plane, and which are arranged so that one end of each faces each other, and which are supported by the seat support frame member and the back seat support frame member, The seat cushion is provided with an angle adjustment mechanism that is installed between the back seat support frame member and the rear leg frame member, and that adjusts and fixes the longitudinal direction of the back seat to form a desired back seat angle with respect to the floor surface while rotating the back seat support frame member around the connection part; and an angle adjustment bow member that has one end connected to a position near the connection part of the seat support frame member, is rotatable within the plane integrally with the seat support frame member, and has the other end that passes through the opening opened in the front leg frame member and does not pass through the opening opened in the rear leg frame member depending on the seat angle, and is adjusted and fixed so that the longitudinal direction of the seat forms the desired seat seat angle with respect to the floor surface.

[0007] According to the present invention, it is possible to freely adjust the seat back angle as well as the seat cushion angle, thereby improving the degree of freedom in training.

[0009] An embodiment of a training bench for carrying out the present invention (hereinafter referred to as "training bench 100") will be described in detail below with reference to the drawings. Regarding the training bench 100, Fig. 1 is a top rear perspective view, Fig. 2 is a bottom rear perspective view, Figs. 3(a) and 3(b) are right and left side views, respectively, Figs. 4(a) and 4(b) are top and bottom views, respectively, and Figs. 5(a) and 5(b) are front and rear views, respectively. In the following description, Figs. 1 to 5 will be referenced as needed unless otherwise specified.

[0010] 1, the front leg frame member 110 can be placed on the floor during training by a foot 136 attached to one end thereof. A handle 138 for transporting the unit is attached to the foot 136, as will be described later with reference to FIG.

[0011] A T-shaped member 140 is attached to one end of the rear leg frame member 112, for example, by bolting or welding, and feet 142a and 142b are attached to the lower ends of the T-shaped member 140, for example, by bolting or welding. This allows the rear leg frame member 112 to be placed on the floor during training. In addition, casters 146a and 146b for movement and transportation are attached to the side surfaces of both ends of the T-shaped member 140, for example, by bolting or welding, as will be described later using Figure 7.

[0012] The front leg frame member 110 and the rear leg frame member 112 are aligned linearly in the longitudinal direction so that their respective longitudinal directions are included in a single imaginary plane (e.g., the plane of the page in FIG. 3 ) perpendicular to the floor surface (see 110 and 112 in FIG. 4( b)). They are also aligned at a predetermined angle α (shown in FIG. 3 ) within that imaginary plane, with their other ends connected by a leg connecting member 114, which serves as a connecting part. The angle α is preferably approximately 120 degrees, for example, so that the training bench 100 can be used stably on the floor. Furthermore, the longitudinal lengths of the front leg frame member 110 and the rear leg frame member 112 are preferably determined based on the longitudinal lengths of the seat 120 and the back seat 122, respectively. The front leg frame member 110 and the rear leg frame member 112 are each provided with a first opening 116 and a second opening 170 (see FIG. 2) through which an angle adjustment bow member 130 (described later) can pass.

[0013] The leg connecting member 114 is connected to the front leg frame member 110 and the rear leg frame member 112 by, for example, bolting or welding.

[0014] The seat support frame member 104 and the back seat support frame member 106 are arranged side by side in their longitudinal directions so that their respective longitudinal directions are included in the aforementioned imaginary plane (see 104 and 106 in Figure 2), and one end of each is connected to the leg connecting member 114 so that they can rotate within the aforementioned imaginary plane around one end of the leg connecting member 114.

[0015] A seat 120 is attached to the seat support frame member 104 by seat brackets 171a / 171b, 172, and 173. Similarly, a back seat 122 is attached to the back seat support frame member 106 by back seat brackets 129a / 129b. The seat 120 and the back seat 122 are arranged side by side in their longitudinal directions so that their respective longitudinal directions are both included in the aforementioned imaginary plane (see 120 and 122 in FIG. 4(a)). One end of the seat 120 and one end of the back seat 122 are attached so as to face each other at a gap 180. A protection plate 150 for protection against contact with the floor surface, which will be described later with reference to FIG. 6, is fastened to the other end of the back seat 122 by, for example, a bolt.

[0016] Here, the seat brackets 171a / 171b, 172, and 173 to which the seat 120 is attached function as a gap adjustment mechanism, and can slide together with the seat 120 along the longitudinal direction of the seat support frame member 104. Then, by inserting a gap adjustment pop pin 173 constituting the seat bracket into any of a plurality of pinholes drilled in the side of the seat support frame member 104, when the seat 120 and the back sheet 122 are adjusted to the desired seat angle and back sheet angle, respectively, as shown in Figures 8, 9, and 10 described below, the gap 180 disappears and one end of the seat 120 and the back sheet 122 can be adjusted to fit snugly together. The gap adjustment pop pin 173 is preferably configured so that when the knob is pulled with a finger, aligned with the pin pole, and then released, the pop pin 173 automatically passes through the pin hole by the force of a spring. It should be noted that the seat brackets 171 a / 171 b , 172 , and 173 are not limited to the above configuration as long as they can slide the seat 120 along the longitudinal direction of the seat support frame member 104 .

[0017] An angle adjustment mechanism is provided between the rear seat support frame member 106 and the rear leg frame member 112. This angle adjustment mechanism adjusts and fixes the longitudinal direction of the rear seat 122 so that it forms a desired rear seat angle with respect to the floor surface while rotating the rear seat support frame member 106 around one end of the leg connection member 114 within the aforementioned imaginary plane. This angle adjustment mechanism is composed of, for example, ratchet rack members 118a / 118b and brace members 124a / 124b. The ratchet rack members 118a / 118b have multiple rack gaps 128a / 128b in their longitudinal directions and are attached to, for example, both left and right side surfaces of the rear leg frame member 112 along their longitudinal directions by three bolt / nut pairs 160-1a / 160-1b, 160-2a / 160-2b, and 160-3a / 160-3b that penetrate the side surfaces of the rear leg frame member 112. The set of brace members 124a, 124b each has one end rotatably connected to the seat back support frame member 106 by a bolt / nut or the like, and the other end is provided with a rod 162 that can engage with one of the sets of rack gaps 128a / 128b on the ratchet rack members 118a / 118b, and a handle 161 that is installed to pass through the center of each brace member and is gripped and operated by the user when adjusting the seat back angle. The user can fix the seat back 122 at a desired seat back angle corresponding to the rack gap 128a / 128b by holding the handle 161 and engaging the rod 162 with one of the sets of rack gaps 128a / 128b on the ratchet rack member 118a / 118b.

[0018] One end of an angle-adjusting bow member 130 is connected to a bracket 190 installed near the leg connection member 114 of the seat support frame member 104. The angle-adjusting bow member 130 is provided rotatably within the aforementioned imaginary plane together with the seat support frame member 104 and the seat 120. The other end of the angle-adjusting bow member 130 passes through a first opening 116 opened in the front leg frame member 110, and may or may not pass through a second opening 170 opened in the rear leg frame member 112 depending on the seat angle, thereby adjusting and fixing the longitudinal direction of the seat 120 to form a desired seat angle with respect to the floor. A plurality of pinholes 132 are opened at a plurality of positions in the arc direction of the angle-adjusting bow member 130. A housing 134-2, to which a seat angle adjustment pop-pin 134-1 is removably attached, is fixedly connected near the first opening 116 of the front leg frame member 110 (see Figures 2, 3(a), and 4(b)). The user adjusts the seat angle of the seat 120 and, while further fine-tuning the seat angle near the desired position, passes the seat angle adjustment pop-pin 134-1 attached to the housing 134-2 through the nearest pinhole 132. As a result, the angle adjustment bow member 130 is fixed to the front leg frame member 110, allowing the seat 120 to be fixed at the desired seat angle. This seat angle adjustment pop-pin 134-1 is preferably designed so that, when the user pulls the knob with a finger, aligns it with the pin pole 132, and then releases the finger, the pop-pin automatically passes through the pinhole 132 due to the force of a spring.

[0019] In the training bench 100 described above, the front leg frame member 110, the rear leg frame member 112, the leg connecting member 114, the T-shaped member 140, the feet 136, 142a, 142b, the seat support frame member 104, the back seat support frame member 106, the angle adjustment bow member 130, the ratchet rack members 118a, 118b, the brace members 124a, 124b, the seat brackets 171a / 171b, 172, 173, the back seat brackets 129a / 129b, the seat angle adjustment pop pin 134-1, the housing 134-2, the rod 162, the feet 136, 142a, 142b, and the housings of the casters 146a, 146b are each made of a high-strength metal, such as iron or stainless steel, and are painted. Note that these components may be made of materials other than metal. The surfaces of the feet 136, 142a, 142b that come into contact with the floor are provided with a cushioning material such as plastic or felt, which is glued to them. The rollers of the casters 146a, 146b are made of rubber, plastic, ABS, or other materials. The material of the rollers is not limited. The handles 138, 161 and the protective plate 150 are made of lightweight metal such as aluminum, with or without painting. The material of the handles 138, 161 and the protective plate 150 is not limited. The seat cushion 120 and the back cushion 122 are each made of, for example, a urethane pad covered with a cover material such as cloth, artificial leather, or plastic, and each include washers for bolting the seat cushion brackets 171a / 171b, 172, 173 and the back cushion brackets 129a / 129b.

[0020] 6 is a diagram showing the arrangement of the training bench 100 when stored. When stored, the training bench 100 can be stored upright so that the protective plate 150 at the end of the back sheet 122 and the housings of the casters 146a, 146b attached to the T-shaped member 140 integral with the rear leg frame member 112 come into contact with the floor surface.

[0021] Figure 7 is a diagram showing the layout of the training bench 100 when it is being moved or transported. When moving or transporting the training bench, from the upright position shown in Figure 6, the rollers of the casters 146a, 146b attached to the T-shaped member 140 integral with the rear leg frame member 112 can be brought into contact with the floor, and the bench can be pulled while grasping the handle 138 attached to the foot 136 integral with the front leg frame member 110.

[0022] Figures 8, 9, and 10 are explanatory diagrams illustrating the setup of the training bench 100 during training. Figure 8 shows the setup when the seat 120 and the back seat 122 are both placed flat (parallel) to the floor. First, the feet 136, 142a, and 142b (not shown) are placed on the floor. Next, to place the seat 120 flat on the floor, the seat angle adjustment pop-pin 134-1 is set to pass through the pinhole 132-1 located slightly inside the angle adjustment bow member 130 (toward the seat support frame member 104). At this time, the angle adjustment bow member 130 passes through the first opening 116 of the front leg frame member 110, and the outer end of the angle adjustment bow member 130 (toward the back seat support frame member 106) slightly passes through the second opening 170 of the rear leg frame member 112. At this time, the gap adjustment pop pin 173 is operated to move the seat cushion 120 forward, i.e., in a direction away from the back seat 122. Furthermore, the rods 162 of the brace members 124a and 124b are engaged with the rack gaps 128a-1 / 128b-1 (not shown) closest to the T-shaped member 140 on the ratchet rack members 118a / 118b (not shown) attached to the rear leg frame member 112 so that the back seat 122 is also flat against the floor. In this state, the angle between the back seat 122 and the seat cushion 120 is 180 degrees. After that, the gap adjustment pop pin 173 may be operated to move the seat cushion 120 backward, i.e., in a direction closer to the back seat 122, and the position of the seat cushion 120 may be adjusted so that the gap 180 between the seat cushion 120 and the back seat 122 disappears.

[0023] FIG. 9 shows a configuration in which the back sheet 122 is placed flat against the floor, as in FIG. 8 , and the seat 120 is placed at a 90-degree angle relative to the back sheet 122, i.e., the angle between the back sheet 122 and the seat 120 is 90 degrees. By widening the gap between the seat and the back as much as possible, the seat can be raised up to 90 degrees, significantly improving the versatility of training. Note that the training bench 100 according to this embodiment can set the angle between the back sheet 122 and the seat 120 to a maximum of 180 degrees and a minimum of 90 degrees. First, as in FIG. 8 , the feet 136, 142a, and 142b (not shown) are placed on the floor. At this time, the gap adjustment pop pin 173 is operated to move the seat 120 to its forwardmost position, i.e., to the position furthest away from the back sheet 122. Next, the seat angle adjustment pop pin 134-1 is set to pass through the pin hole 132-2 on the outermost side (the side closest to the back seat support frame member 106) of the angle adjustment bow member 130 so that the seat 120 is in an upright position (at a 90-degree angle relative to the back seat 122). At this time, the angle adjustment bow member 130 is pulled out to the maximum extent toward the seat 120, just barely passing through the first opening 116 of the front leg frame member 110, but the outer end (the side closest to the back seat support frame member 106) of the angle adjustment bow member 130 is separated from the rear leg frame member 112 and does not pass through the second opening 170. Also, at this time, the upright seat 120 is at the tip (top) of the seat support frame member 104, so it does not interfere with the back seat 122. 8, the rods 162 of the brace members 124a, 124b are engaged with the rack gaps 128a-1 / 128b-1 (not shown) closest to the T-shaped member 140 on the ratchet rack members 118a / 118b (not shown) attached to the rear leg frame member 112 so that the back seat 122 is flat against the floor. In this state, the angle formed between the back seat 122 and the seat cushion 120 is 90 degrees.The gap adjusting pop pin 173 may be operated to move the seat sheet 120 downward, thereby adjusting the position of the seat sheet 120 so that the gap 180 between the seat sheet 120 and the back sheet 122 disappears.

[0024] FIG. 10 shows a configuration in which the back seat 122 is installed at a large incline relative to the floor surface, and the seat cushion 120 and the back seat 122 are installed flat relative to each other, i.e., the angle between the back seat 122 and the seat cushion 120 is 180 degrees. First, as in the case of FIG. 8 or FIG. 9, the feet 136, 142a, and 142b (not shown) are placed on the floor. At this time, the gap adjustment pop pin 173 is operated to move the seat cushion 120 forward, i.e., to a position separated from the back seat 122. Next, the rods 162 of the brace members 124a and 124b are engaged with the rack gaps 128a-2 / 128b-2 (not shown) located on the inner side (toward the back seat 122) of the ratchet rack members 118a / 118b (not shown) attached to the rear leg frame member 112 so that the back seat 122 rises relative to the floor surface. Next, the seat angle adjustment pop pin 134-1 is set to pass through the pin hole 132-3 on the innermost side (the seat support frame member 104 side) of the angle adjustment bow member 130 so that the seat cushion 120 is flat against the back seat 122. At this time, the angle adjustment bow member 130 is pushed all the way into the first opening 116 of the front leg frame member 110, penetrating it, and the outer end of the angle adjustment bow member 130 (the back seat support frame member 106 side) is also pushed all the way into the second opening 170 of the rear leg frame member 112, penetrating it. At this time, because the back seat 122 is raised, the rear leg frame member 112 and the back seat 122 are separated by a large distance, allowing the angle adjustment bow member 130 to pass through the second opening 170 to a large extent. In this state, the angle between the back seat 122 and the seat cushion 120 is 180 degrees. Thereafter, the gap adjusting pop pin 173 may be operated to move the seat sheet 120 in a direction approaching the back sheet 122, and the position of the seat sheet 120 may be adjusted so that the gap 180 between the seat sheet 120 and the back sheet 122 disappears.

[0025] As described above, the training bench 100 of this embodiment allows for greater freedom in setting the seat angle and back seat angle.
