[0003] [Patent Document 1] Utility Model Registration No. 3234794 [Patent Document 2] Utility Model Registration No. 3232378 Summary of the Invention [Problem to be solved by the invention]

[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. [Means for solving the problem]

[0006] A training bench according to one embodiment of the present invention comprises a front leg frame member and a rear leg frame member, each of which can be placed on a floor surface during training, and which are arranged side by side in the longitudinal direction so that their respective longitudinal directions are both included in a single imaginary plane perpendicular to the floor surface, and whose other ends are connected by a connecting portion so as 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 so that their respective longitudinal directions are both included in the plane, and one end of each of which is connected to the connection portion so that each of which can rotate within the plane around the connection portion, and which have a first opening and a second opening, respectively; a seating surface and a back seat that are arranged side by side in the longitudinal direction so that their respective longitudinal directions are both included in the plane, and that are arranged so that one end of each of them faces each other, and that are supported by the seating surface and back seat support frame members, respectively; 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 back seat so that the longitudinal direction of the back seat forms 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-adjusting bow member, one end of which is connected to a position near the connection portion of the seat support frame member and is rotatable within the plane integrally with the seat support frame member, and the other end of which passes through the opening in the front leg frame member and does not pass through the opening in the rear leg frame member depending on the seat angle, and which is adjusted and fixed so that the longitudinal direction of the seat forms the desired seat angle with respect to the floor surface. [Effects of the Invention]

[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. [Brief explanation of the drawings]

[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 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] As shown in Figure 1, the front leg frame member 110 can be placed on the floor during training by a foot 136 attached to one end of the front leg frame member 110. A handle 138 for transporting the unit is attached to the foot 136, as will be described later with reference to Figure 7.

[0011] A T-shaped member 140 is attached to one end of the rear leg frame member 112 by, for example, bolting or welding, and feet 142a and 142b are attached to the lower ends of the T-shaped member 140 by, for example, bolting or welding. This allows the rear leg frame member 112 to be in contact with the floor during training. As will be described later with reference to FIG. 7, casters 146a and 146b for transport are attached to both end side surfaces of the T-shaped member 140 by, for example, bolting or welding.

[0012] The front leg frame member 110 and the rear leg frame member 112 are arranged in a straight line along their longitudinal direction so that their respective longitudinal directions are both included in a single imaginary plane (e.g., the plane of the paper in Figure 3) perpendicular to the floor surface (see 110 and 112 in Figure 4(b)), and are arranged so as to form a predetermined angle α shown in Figure 3 within that imaginary plane, with their other ends connected by a leg connecting member 114, which is the connecting part. The angle α is preferably about 120 degrees, for example, so that the training bench 100 can be used stably on the floor. Furthermore, it is preferable that the longitudinal lengths of the front leg frame member 110 and the rear leg frame member 112 are determined based on the longitudinal lengths of the seat cushion 120 and the back seat 122, respectively. The front leg frame member 110 and the rear leg frame member 112 are provided with a first opening 116 and a second opening 170 (see FIG. 2), respectively, through which an angle adjustment bow member 130, which will be 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 virtual 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 virtual 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 171 a / 171 b , 172 and 173 . Similarly, a back seat 122 is mounted on the back seat support frame member 106 by back seat brackets 129a / 129b. The seating surface sheet 120 and the back sheet 122 are arranged side by side in the longitudinal direction so that the longitudinal directions of both are included in the above-mentioned imaginary plane (see 120 and 122 in FIG. 4(a)). The seating surface sheet 120 and the back sheet 122 are attached so that their respective ends face each other at a gap 180 . A protection plate 150 for preventing contact with the floor surface is fastened to the other end of the back sheet 122 by, for example, a bolt, as will be described later with reference to FIG.

[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 passing a gap adjustment pop pin 173 constituting the seat bracket through any of a plurality of pinholes drilled in the side of the seat support frame member 104, as shown in Fig. 8, Fig. 9, or Fig. 10 described later, when the seat 120 and the back sheet 122 are adjusted to the desired seat angle and back sheet angle, respectively, the gap 180 disappears and adjustment can be made so that one end of the seat 120 and one end of the back sheet 122 fit snugly together. The gap adjustment pop pin 173 is preferably configured so that when the knob is pulled with a finger, the pop pin 173 is aligned with the pin hole and then released, and the pop pin 173 is automatically inserted into the pin hole by the force of a spring. Note that the seat brackets 171a / 171b, 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] Between the back seat support frame member 106 and the rear leg frame member 112, an angle adjustment mechanism is provided which rotates the back seat support frame member 106 around one end of the leg connection member 114 within the aforementioned virtual plane, and adjusts and fixes the longitudinal direction of the back seat 122 so that it forms a desired back seat angle with respect to the floor surface. 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 direction and are attached to, for example, both left and right side surfaces of the rear leg frame member 112 along its longitudinal direction by three sets of 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 has one end rotatably connected to the seat back support frame member 106 by a bolt / nut or the like, and has a rod 162 attached to the other end 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 and is gripped and operated by the user when adjusting the seat back angle. The user can hold the handle 161 and engage the rod 162 with a set of rack gaps 128a / 128b on the ratchet rack members 118a / 118b to fix the back seat 122 at the desired back seat angle corresponding to the rack gaps 128a / 128b.

[0018] One end of the 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 integrally with the seat support frame member 104 and the seat 120. The other end of this 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, and is adjusted and fixed so that the longitudinal direction of the seat 120 forms a desired seat angle with respect to the floor. The angle-adjusting bow member 130 has a plurality of pinholes 132 bored at a plurality of positions in the arc direction. 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 FIG. 2, FIG. 3(a), or FIG. 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 pinhole 132 closest to it. As a result, the angle-adjusting bow member 130 is fixed to the front leg frame member 110, and the seat 120 can be fixed at the desired seat angle. The pop pin 134-1 for adjusting the seat angle is preferably constructed so that when the knob is pulled with a finger, aligned with the pin hole 132, and then released, the pop pin 134-1 will automatically pass through the pin hole 132 due to the force of the 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, and 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 and 118b, the brace members 124a and 124b, the seat brackets 171a / 171b, 172, and 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, and 142b, and the housings of the casters 146a and 146b are each made of a high-strength metal, such as iron or stainless steel, and are painted. However, these components may be made of materials other than metal. A cushioning material such as plastic or felt is glued to the surfaces of the feet 136, 142a, 142b that come into contact with the floor. The rollers of the casters 146a and 146b are made of rubber, plastic, ABS, etc. However, the material of the rollers is not limited. The handles 138, 161 and the protective plate 150 are made of a lightweight metal such as aluminum, which may or may not be painted. However, the materials of the handles 138, 161 and the protective plate 150 are not limited. The seat surface 120 and the back surface 122 are each made of, for example, a urethane pad member covered with a cover material such as cloth, artificial leather, or plastic, and also incorporate washers for bolting the seat surface brackets 171a / 171b, 172, 173 and the back surface brackets 129a / 129b.

[0020] 6 is a diagram showing the stored layout of the training bench 100. When stored, the training bench 100 can be stored upright so that the protective plate 150 at the end of the back seat 122 and the housings of the casters 146a, 146b attached to the T-shaped member 140 integrated 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] 8, 9, and 10 are explanatory diagrams of the setup of the training bench 100 during training. Fig. 8 shows the setup when the seat surface 120 and the back sheet 122 are both placed flat (parallel) to the floor surface. First, the feet 136, 142a, 142b (not shown) are placed on the floor. Next, the seat angle adjustment pop pin 134-1 is set to pass through the pin hole 132-1 slightly inside (towards the seat support frame member 104) of the angle adjustment bow member 130 so that the seat 120 is flat against the floor. At this time, the angle adjustment bow member 130 passes through the first opening 116 of the front leg frame member 110, and the end of the angle adjustment bow member 130 on the outside (towards 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 120 forward, i.e., in the 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 formed between the back seat 122 and the seat cushion 120 is 180 degrees. Thereafter, the gap adjustment pop pin 173 may be operated to move the seat cushion 120 rearward, i.e., in a direction closer to the back seat 122, thereby adjusting the position of the seat cushion 120 so that the gap 180 between the seat cushion 120 and the back seat 122 disappears.

[0023] 9 shows a configuration in which the back sheet 122 is placed flat against the floor, as in the case of 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. 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, the feet 136, 142a, and 142b (not shown) are placed on the floor in the same manner as in Fig. 8. At this time, the gap adjustment pop pin 173 is operated to move the seat cushion sheet 120 to the most forward position, i.e., to the position farthest from the back seat 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 toward the seat 120 and passes just barely 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 its 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 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 flat against the floor. In this state, the angle formed between the back seat 122 and the seat cushion 120 is 90 degrees. Note that the gap adjustment pop pin 173 may be operated to move the seat cushion 120 downward and adjust the position of the seat cushion 120 so that the gap 180 between the seat cushion 120 and the back seat 122 disappears.

[0024] FIG. 10 shows a configuration in which the back sheet 122 is set at a large incline relative to the floor surface, and the seating surface 120 and the back sheet 122 are set flat relative to each other, i.e., the angle between the back sheet 122 and the seating surface 120 is set at 180 degrees. First, the feet 136, 142a, 142b (not shown) are placed on the floor, as in the case of Fig. 8 or Fig. 9. At this time, the gap adjustment pop pin 173 is operated to move the seat cushion sheet 120 forward, i.e., to a position separated from the back seat sheet 122. Next, the rods 162 of the brace members 124a, 124b are engaged with the rack gaps 128a-2 / 128b-2 (not shown) located on the inner side (towards the rear seat 122) of the ratchet rack members 118a / 118b (not shown) attached to the rear leg frame member 112 so that the rear seat 122 rises above 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 to pass through, 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 to pass through. 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 sheet 122 and the seating surface sheet 120 is 180 degrees. After that, the gap adjustment pop pin 173 may be operated to move the seating surface sheet 120 in a direction closer to the back sheet 122, thereby adjusting the position of the seating surface sheet 120 so that the gap 180 between the seating surface sheet 120 and the back sheet 122 disappears.

[0025] As described above, the training bench 100 of this embodiment makes it possible to improve the degree of freedom in setting the seat angle and the back seat angle. [Explanation of symbols]
