  Embodiments of the present invention will be described below with reference to the drawings.

First, an example of a training apparatus using the safety device according to the present embodiment will be described.
FIG. 1 is a diagram illustrating an appearance of the training apparatus 100. The training device 100 is a device that performs balance training for a person who cannot secure balance. As shown in FIG. 1, the training apparatus 100 includes a moving body 200, a display 120, a frame 102, a hoisting machine 106, a hanger 110, and the safety device 1.

  The moving body 200 moves on the trainer P while maintaining the inverted state by operating the trainer P. The display 120 instructs the trainee P where to move the moving body 200 according to the training menu. The frame 102 is a skeleton of the training device 100. The hoisting machine 106 is a height adjusting device for the hanger 110, and is attached to a position above the trainee P in the frame 102. The hoisting machine 106 has, for example, an electric motor, and the height of the hanger 110 is adjusted by hoisting the lifting wire 104 provided with the hanger 110 at one end by the electric motor. The hanger 110 has arm portions 110a on the left and right sides, and a lanyard 3 of the safety device 1 described later is attached to the tip of the arm portion 110a.

  Since the body of the trainee P is held by the safety device 1 during training, the impact received by the trainer P can be reduced even when the trainee P falls. The trainer P performs a predetermined training while viewing the screen displayed on the display 120 in a state where the trainee P is on the moving body 200. For this reason, it is necessary for the safety device 1 to be configured so as not to obstruct the field of view of the trainee P during training.

  FIG. 2 is a diagram illustrating a schematic configuration of the safety device 1 according to the present embodiment. In addition, with the trainer P wearing the safety device 1, the front side is defined as the front, the back side is the rear, the left side is the left, and the right side is the right. As shown in FIG. 2, the safety device 1 includes a harness 2 as a brace and a lanyard 3 as two strips.

  The harness 2 is attached to the upper body of the trainee P. The harness 2 includes a belt 2a wound around the waist of the trainee P and a suspension band 2b attached to the trainer P in a suspender shape. Moreover, the harness 2 is connected with the lanyard 3 mentioned later in the lanyard connection part 2c.

The configuration of the lanyard 3 will be described below.
FIG. 3 is a diagram showing a schematic configuration of the lanyard 3. As shown in FIG. 3, the lanyard 3 is provided with a hanger connecting portion 3a for connecting to the hanger 110 at the upper end portion and a harness connecting portion 3b at the lower end portion. The hanger connection part 3a is formed in a ring shape so that it can be hooked on the tip of the arm part 110a. For example, one of the lanyard connecting portion 2c (see FIG. 2) of the harness 2 and the harness connecting portion 3b of the lanyard 3 may be configured by a tongue plate and the other by a buckle. As the tongue plate and the buckle, common ones used for connecting parts such as seat belts can be used. The configurations of the lanyard connecting portion 2c and the harness connecting portion 3b are not limited to the configuration using the tongue plate and the buckle, and any configuration is possible as long as the harness 2 and the lanyard 3 can be easily connected and separated. May be. The connection position between the harness 2 and the lanyard 3 will be described later.

  The lanyard 3 is formed by a member having rigidity capable of maintaining a predetermined shape even during training. 4 is a cross-sectional view taken along line IV-IV in FIG. As shown in FIGS. 3 and 4, the cover 3 c of the lanyard 3 is formed with a bag binding space 3 d at both ends in the short direction. Core wires 3e made of metal or the like are inserted into the bag binding spaces 3d. In order to make the lanyard 3 difficult to twist, the core wires 3e inserted into the bag binding spaces 3d at both ends are connected at the ends so as to form an integral structure. Thereby, the lanyard 3 can maintain a predetermined shape even in a state where the body of the trainee P is held during training.

The predetermined shape of the lanyard 3 in a state where the lanyard 3 holds the body of the trainee P will be described below.
5A and 5B are diagrams illustrating a predetermined shape of the lanyard 3 in a state where the lanyard 3 holds the body of the trainee P. 5A is a view of the trainee P as viewed from the front, and FIG. 5B is a view of the trainee P as viewed from the right side. As shown to FIG. 5A, the lanyard 3 is curving in the direction (arrow A, B in the figure) which left | separated from the trainee P's head H to the side. Furthermore, as shown to FIG. 5B, the lanyard 3 is curving in the direction away from the trainee's head H to the back (arrow C in the figure). By forming the lanyard 3 in this way, it is possible to reduce the possibility of hindering the view of the trainee P during training.

The connection position of the harness 2 and the lanyard 3 will be described below.
FIG. 6A and FIG. 6B are diagrams for explaining a connection position between the harness 2 and the lanyard 3. 6A and 6B are views of the trainee P as viewed from the front. As shown in FIG. 6A, it is assumed that the lanyard 3 is not curved in a direction (arrows A and B in the figure) away from the head H of the trainee P to the side. In order to prevent the lanyard 3 from obstructing the trainee's view during training, at least the width L1 between the lanyard connecting portions is made wider than the sum of the interauricular width L2 and twice the lanyard width L3. (Width L1 between lanyard connecting portions> auricle spacing L2 + lantern width L3 × 2). That is, it is necessary to ensure a certain clearance L5 between the trainee P's head and the lanyard 3.

  As shown in FIG. 6B, a straight line distance between the left and right acromion points (outer edges of the acromial scapula) is defined as an acromial width L4. In order to make the width L1 between the lanyard connecting portions wider than the sum of the interauricular width L2 and twice the lanyard width L3, the width L1 between the lanyard connecting portions is substantially equal to the shoulder width L4 of the trainee P. It is preferable to connect the harness 2 and the lanyard 3 at a position equal to (L1≈L4).

  FIG. 7 shows the clearance L5 (see FIG. 6) between the head of the trainee P and the lanyard 3 when the width L1 between the lanyard connections is substantially equal to the shoulder width L4 of the trainee P. It is a figure which shows an example of a result. The clearance L5 between the trainee P's head and the lanyard 3 can be calculated by {width L1-between lanyard connecting portions (auricle interval L2 + lanyard width L3 × 2)} / 2. The width of the lanyard 3 is 35 mm.

  Note that the numerical values of the shoulder width and the pinna interval in FIG. 7 are based on the “AIST human body size database 1991-92” which is a database issued by the National Institute of Advanced Industrial Science and Technology. “Elderly group girls” means 50 subjects over 60 years old, “Elderly group boys” means 50 subjects over 60 years old, and “Adolescent group girls” means between 18 and 30 years old. 204 female subjects, “young boys”, are 217 male subjects who are 18 years old and younger than 30 years old. The “percentile” is a term indicating what percentage the subject group corresponds to when placed in order from the smallest. That is, the percentile 2.5 means the 2.5% order from the smallest in each subject group, and the percentile 97.5 means the 97.5% order from the smallest in the population.

  As shown in FIG. 7, regardless of the physique of the trainee P, the clearance L5 between the trainee P's head and the lanyard 3 is ensured to be 35 mm or more. If the clearance L5 is 35 mm or more, it is considered that the lanyard 3 is less likely to obstruct the trainee P's view during training. Therefore, by connecting the harness 2 and the lanyard 3 at a position where the width L1 between the lanyard connecting portions is substantially equal to the shoulder width L4 of the trainee P, the head H of the trainee P of the lanyard 3 is connected. Even when the curvature in the direction away from the side to the side is very small (or when there is no curvature), the possibility of hindering the field of view of the trainee P during training can be reduced.

  As described above, according to the present invention, it is possible to ensure the safety of the trainee without obstructing the trainee's view during training.

[Modification]
A modification of the lanyard structure will be described below.
FIG. 8 is a diagram showing a schematic configuration of the lanyard 303. 9 is a cross-sectional view taken along line IX-IX in FIG. As shown in FIGS. 8 and 9, the lanyard 303 has a hanger connecting portion 3a for connecting to the hanger 110 (see FIG. 1) at the upper end portion and a harness at the other end, like the lanyard 3 (see FIG. 3). A connecting portion 3b is provided. The shape of the lanyard 303 is the same as the shape of the lanyard 3 described with reference to FIG.

  The lanyard 303 is encapsulated with a resin plate 303e in the interior 303c so that the lanyard 303 is maintained in a predetermined shape even during training. The resin plate 303e has a shape with low rigidity in the longitudinal direction and high rigidity in the short direction. For example, a plurality of ribs extending in the lateral direction and arranged in the longitudinal direction are provided on the surface of the resin plate 303e. By configuring the lanyard 303 in this way, the lanyard 3 is easy to extend in the longitudinal direction and is difficult to twist. Thereby, the lanyard 3 can maintain a predetermined shape even during training.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
