[Figure 11]This figure shows the seated position of the sixth embodiment described above, where (A) is a front view and (B) is a side view. [Modes for carrying out the invention]

[0026] Next, embodiments for carrying out the present invention will be described. In the following explanation, the direction of arrow F in the diagram will be considered forward, and the opposite direction will be considered backward.

[0027] [First Embodiment] Figures 1 to 3 show a standing posture support device according to the first embodiment of the present invention. This example is explained with the right direction in Figure 1 being the front.

[0028] [Overall structure] The standing posture support device of this embodiment comprises a base portion 10, an upright portion 20 that stands upright above the base portion 10, and a backrest portion 30 provided on the upper part of the upright portion 20.

[0029] [Base section 10] In this example, the base portion 10 is formed by curving a steel pipe into a roughly U-shape. The base portion 10 has a foot-operated portion 11 that the user can step on with their feet. In this example, the portion corresponding to the connecting side that connects the two sides of the roughly U-shape described above mainly functions as the foot-operated portion 11.

[0030] [Standing section 20] In this example, the upright section 20 is formed by bending a steel pipe in a continuous manner with the base section 10. In other words, the upright section 20 is formed by steel pipes extending from both sides of the roughly U-shaped structure described above, each pipe being bent forward in a V-shape, and then their ends being bent vertically upward, so that it stands upright above the base section 10. The two steel pipes on the left and right are reinforced by fixing a first reinforcing bar 12 to the rear bends. Similarly, the two steel pipes on the left and right are reinforced by fixing a second reinforcing bar 22 to the upper bends.

[0031] [Backrest section 30] A backrest portion 30 is provided on the upper part of the upright portion 20. In this example, the backrest portion 30 is composed of a pair of swinging arms 32 and a support member 33 attached across both swinging arms 32.

[0032] In this example, the two swinging arms 32 that constitute the backrest portion 30 are supported so as to be swingable by a pair of ratchet gears 31 provided at the upper end of the upright portion 20. As a result, the backrest portion 30 is configured to be switchable between a support state that supports the user's standing posture (Figure 1(A)) and a seated state that allows the user to sit down (Figure 1(B)).

[0033] The ratchet gear 31 functions as a switching means for switching between a support state and a seated state for the backrest portion 30, and the switching between the support state and the seated state can be performed by the ratchet gear 31. The ratchet gear 31 is a conventionally known type and can swing the swing arm 32 and the support member 33 between the support state and the seated state, temporarily maintaining their position in the support state and temporarily maintaining their position in the seated state.

[0034] The seated state is when the swinging arm 32 and the support member 33 are in a horizontal position, and the supported state is when the swinging arm 32 and the support member 33 are in a vertical position. The ratchet gear 31 swings the swinging arm 32 and the support member 33 between the supported state and the seated state, and its ratchet mechanism also allows the swinging arm 32 and the support member 33 to be temporarily maintained at any angle between the vertical and horizontal positions.

[0035] In other words, the support state in which the swinging arm 32 and the support member 33 are vertical is the limit position of the forward swing angle, and in this state the ratchet gear 31 maintains that position. In this support state, the user can stabilize the standing posture support device with their body weight by stepping on the foot pedal 11, and can reduce fatigue by leaning their back and waist against the backrest 30 in the support state.

[0036] The device is configured to switch to the seated position by tilting the backrest portion 30 in the support position backward. By pushing the backrest portion 30 in the support position slightly forward, the ratchet is released, and the backrest portion 30 can be tilted backward to the seated position. The seated position, when the swing arm 32 and the support member 33 are horizontal, is the limit of the backward swing angle, and the ratchet gear 31 maintains this position. In this seated position, the user can rest by sitting on the support member 33.

[0037] When the backrest 30 is swung forward from the seated position described above, the ratchet gear 31 allows the backrest 30 to be stopped at any angle and maintained in that position. The user can adjust the backrest 30 to their preferred angle to lean their back or waist against it or sit on it. Swinging the swaying arm 32 and the support member 33 until they are vertical returns them to the support position described above.

[0038] In this example, the rear end position of the backrest portion 30 in the seated position (arrow R in Figure 3) is configured to be at the same position as or further forward than the rear end position of the base portion 20 (arrow B in Figure 3). By doing so, the standing posture support device is stabilized when the user sits on the backrest portion 30 in the seated position, reducing the risk of falling or other accidents.

[0039] [Effects of the First Embodiment] As described above, the first embodiment provides the following effects.

[0040] The standing posture support device of the first embodiment described above comprises a base portion 10, an upright portion 20 that stands upright above the base portion 10, and a backrest portion 30 provided on the upper part of the upright portion 20. The backrest portion 30 is configured to be switchable between a support state that supports the user's standing posture and a seated state that allows the user to sit down. Therefore, the user can reduce fatigue from standing by leaning their back and waist against the backrest portion 30 in the support state. Furthermore, by switching the backrest portion 30 to the seated state, the user can also rest by sitting on the backrest portion 30 in the seated state. Thus, the standing posture support device of the present invention not only supports the standing posture but also allows for a light rest by sitting down on the spot.

[0041] The standing posture support device of the first embodiment described above has a footrest 11 on the base 10 that the user can step on with their feet. Therefore, when the user steps on the footrest 11, mainly in a standing position, the user's weight stabilizes the standing posture support device when the user leans their back or waist against the backrest 30 in the supported state, reducing the risk of falling. In addition, when the user moves away from the footrest 11, the standing posture support device can be easily carried.

[0042] The standing posture support device of the first embodiment described above is configured to switch to the seated state by tilting the backrest portion 30 in the support state backward. Therefore, the seated state can be easily switched to by tilting the backrest portion 30 in the support state backward.

[0043] In the first embodiment of the standing posture support device described above, the rear end position of the backrest portion 30 when in a seated position is located at the same position as or further forward than the rear end position of the base portion 10. Therefore, when the user sits on the backrest portion 30 in a seated position, the standing posture support device is stable, reducing the risk of falling over.

[0044] [Second Embodiment] Figure 4 shows a standing posture support device according to a second embodiment of the present invention. This example is described with the right direction in Figure 4 being the front.

[0045] In this example, the base portion 10 is configured to include a pair of legs 14 extending front to back, and a footrest plate 15 positioned towards the front between the two legs 14.

[0046] Furthermore, the upright section 20 is formed from a pair of support columns 16, each consisting of a square pipe standing upright on top of the two leg sections 14. The upper parts of the two support columns 16 are reinforced by fixing reinforcing crossbars 27 made of square pipes.

[0047] Furthermore, a rod-shaped footrest 28 is provided on the lower part of both support columns 16. The footrest 28 allows the user to rest one foot by placing it on it while standing.

[0048] A ratchet gear 31 is attached to the upper part of each of the two support columns 16, and a pair of swinging arms 32 are supported by the ratchet gears 31 so that they can swing. A support member 33 is attached across both swinging arms 32, and the support member 33 across both swinging arms 32 constitutes a backrest section 30.

[0049] Otherwise, it is the same as the first embodiment described above, the same parts are denoted by the same reference numerals, and it produces the same effects and advantages as the first embodiment.

[0050] [Third Embodiment] Figure 5 shows a standing posture support device according to a third embodiment of the present invention. This example is described with the right direction in Figure 5 being the front.

[0051] In this example, the base portion 10 is a floor fixing portion 13 that can be fixed to the floor surface. In the illustrated example, the floor fixing portion 13 is embedded in a part that makes up the floor surface (for example, a concrete foundation). Otherwise, it is the same as the second embodiment described above, and the same parts are denoted by the same reference numerals.

[0052] In the third embodiment of the standing posture support device described above, the base portion 10 is a floor fixing portion 13 that can be fixed to the floor surface. Therefore, because the base portion 10, which is the floor fixing portion 13, is fixed to the floor surface, when the user leans their back or waist against the backrest portion 30 in the support state while standing, the risk of falling is avoided. The same applies when the user sits on the backrest portion 30 in the seated state. Otherwise, it exhibits the same effects and advantages as the second embodiment described above.

[0053] [Fourth Embodiment] Figure 6 shows a standing posture support device according to the fourth embodiment of the present invention. This example is described with the left direction in Figure 6 being the front.

[0054] In this example, the seated position is switched by tilting the backrest portion 30 in the support position forward. Otherwise, it is the same as the second embodiment described above, and the same parts are denoted by the same reference numerals.

[0055] The standing posture support device of the fourth embodiment described above is configured to switch to the seated state by tilting the backrest portion 30 in the support state forward. By tilting the backrest portion 30 in the support state forward, it is possible to easily switch to the seated state. Otherwise, it exhibits the same effects and advantages as the second embodiment described above.

[0056] [Fifth Embodiment] Figures 7 to 9 illustrate a standing posture support device according to a fifth embodiment of the present invention.

[0057] In this example, the base portion 10 is configured to include a forefoot portion 41 located in front of the backrest portion 30 and a rearfoot portion 45 located behind the backrest portion 30.

[0058] In this example, the upright portion 20 includes a first upright portion 51 to which the backrest portion 30 is attached in conjunction with the rear foot portion 45, and a second upright portion 55 that is attached in conjunction with the front foot portion 41 and fixed to the first upright portion 51. The first upright portion 51 and the second upright portion 55 are joined by welding or other methods in such a way that the front foot portion 41 and the rear foot portion 45 make contact with the floor surface.

[0059] The forefoot portion 41 is composed of two steel pipes extending forward and two footrests 15 (which form the footrest) connecting the two steel pipes. The second upright portion 55, which is continuous with the forefoot portion 41, is a roughly U-shaped steel pipe that extends upward from the two pipes and bends upward. The roughly U-shaped horizontal bar 56 of the second upright portion 55 functions as a reinforcing bar and a footrest.

[0060] In this example as well, the rear end position of the backrest 30 in the seated position is configured to be at the same position as or further forward than the rear end position of the base 10 (i.e., the rear foot section 45). Therefore, when the user sits on the backrest 30 in the seated position, the standing posture support device is stabilized, reducing the risk of falling or other accidents.

[0061] The rear foot portion 45 is made of a roughly U-shaped steel pipe. The first upright portion 51, which is continuous with the rear foot portion 45, is made up of two support columns 51A that are bent upward and stand upright, continuously from the open end of the roughly U-shaped steel pipe. An inner pipe 51B is inserted through each of the support columns 51A from above.

[0062] A ratchet gear 31 is attached to the upper end of each of the inner pipes 51B, and a pair of swinging arms 32 are supported by the two ratchet gears 31 so that they can swing. A support member 33 is attached across both swinging arms 32, forming a backrest section 30. The two support columns 51A are connected by a first reinforcing bar 52, and the two inner pipes 51B are connected by a second reinforcing bar 53.

[0063] Figure 9 illustrates the lifting mechanism for adjusting the height of the backrest section 30.

[0064] A pair of opposing lock holes 61 are drilled in the upper peripheral wall of the support column 51A. A lock pin 62 is inserted through the lock holes 61. The inner pipe 51B, which is inserted into the support column, has a pair of opposing adjustment holes 63 through which the lock pin 62 can be inserted. Multiple adjustment holes 63 are formed at predetermined intervals along the longitudinal direction of the inner pipe 51B. The height of the backrest portion 30 can be adjusted by sliding the inner pipe 51B within the support column 51A to adjust its height, aligning the adjustment hole 63 of the desired height with the lock hole 61, and passing the lock pin 62 through the aligned lock hole 61 and adjustment hole 63.

[0065] The lock pin 62 is integrated with a C-shaped pin holder 64 made of synthetic resin. The tip of the lock pin 62 is located in the center of the C-shaped opening, and the lock pin 62 is positioned to pass through the center of the C-shape and is integrated with it. The pin holder 64 is designed to hold the support column 51A when the lock pin 62 passes through the lock hole 61 and the adjustment hole 63 and reaches the locked position.

[0066] The two support columns 51A are connected by a first reinforcing bar 52, and the two inner pipes 51B are connected by a second reinforcing bar 53. Therefore, when the inner pipes 51B are removed from the support columns 51A with the backrest section 30 installed, the distance between the support columns 51A and the distance between the inner pipes 51B are kept stable. This makes it easy to reinsert the inner pipes 51B into the support columns 51A.

[0067] The standing posture support device of the fifth embodiment described above has a base portion 10 that includes a front foot portion 41 located in front of the backrest portion 30, and a rear foot portion 45 located behind the backrest portion 30. Primarily in a standing position, when the user steps on the foot portion of the front foot portion 41 with their foot, the user's weight stabilizes the standing posture support device when leaning their back or waist against the backrest portion 30 in the supported state, thereby reducing the risk of falling. Furthermore, when the user moves away from the foot portion, the standing posture support device can be easily carried. In addition, because the rear foot portion 45 is located behind the backrest portion 30, the standing posture support device is stable, reducing the risk of falling.

[0068] The standing posture support device of the fifth embodiment described above has a standing portion 20 which includes a first standing portion 51 to which the backrest portion 30 is attached in conjunction with the rear foot portion 45, and a second standing portion 55 which is attached in conjunction with the front foot portion 41 and fixed to the first standing portion 51. With this configuration, the standing posture support device can be manufactured by first creating the first standing portion 51 which is in conjunction with the rear foot portion 45 and the second standing portion 55 which is in conjunction with the front foot portion 41, and then fixing the second standing portion 55 to the first standing portion 51, making it easier to manufacture.

[0069] Otherwise, it produces the same effects and advantages as the first and second embodiments described above.

[0070] [Sixth Embodiment] Figures 10 and 11 show a standing posture support device according to the sixth embodiment of the present invention.

[0071] In this example, the base portion 10 is configured to include a forefoot portion 41 located in front of the backrest portion 30 and a rearfoot portion 45 located behind the backrest portion 30.

[0072] In this example, the upright portion 20 includes a first upright portion 51 to which the backrest portion 30 is attached in conjunction with the rear foot portion 45, and a second upright portion 55 that is attached in conjunction with the front foot portion 41 and fixed to the first upright portion 51. The first upright portion 51 and the second upright portion 55 are joined by welding or other methods in such a way that the front foot portion 41 and the rear foot portion 45 make contact with the floor surface.

[0073] The forefoot section 41 is composed of two steel pipes extending forward and two footrests 15 (which form the footrest) connecting the two steel pipes. The second upright section 55, which is continuous with the forefoot section 41, is a roughly U-shaped steel pipe that extends upward from the two pipes and bends upward. In this example, the second upright section 55 bends forward in a "V" shape midway. A footrest 28 is attached slightly below the "V" shaped bend. The U-shaped horizontal bar 49 of the second upright section 55 functions as a reinforcing bar.

[0074] The rear leg portion 45 is composed of a horizontal bar 47 made of steel pipe that is bent into a roughly U-shape. The first upright portion 51, which is continuous with the rear leg portion 45, consists of two support columns 51A, which are vertical bars that are roughly U-shaped and bent slightly backward midway upright. A ratchet gear 31 is attached to the upper end of each of the support columns 51A, and a pair of swinging arms 32 are supported by the two ratchet gears 31 so that they can swing. A support member 33 is attached across the two swinging arms 32, forming the backrest portion 30.

[0075] In this example as well, the rear end position of the backrest 30 in the seated position is configured to be at the same position as or further forward than the rear end position of the base 10 (i.e., the rear foot section 45). Therefore, when the user sits on the backrest 30 in the seated position, the standing posture support device is stabilized, reducing the risk of falling or other accidents.

[0076] The standing posture support device of the sixth embodiment described above has a base portion 10 that includes a front foot portion 41 located in front of the backrest portion 30, and a rear foot portion 45 located behind the backrest portion 30. Primarily in a standing position, when the user steps on the foot portion of the front foot portion 41 with their foot, the user's weight stabilizes the standing posture support device when leaning their back or waist against the backrest portion 30 in the supported state, thereby reducing the risk of falling. Furthermore, when the user moves away from the foot portion, the standing posture support device can be easily carried. In addition, because the rear foot portion 45 is located behind the backrest portion 30, the standing posture support device is stable, reducing the risk of falling.

[0077] The standing posture support device of the sixth embodiment described above has a standing portion 20 which includes a first standing portion 51 to which the backrest portion 30 is attached in conjunction with the rear foot portion 45, and a second standing portion 55 which is attached in conjunction with the front foot portion 41 and fixed to the first standing portion 51. With this configuration, the standing posture support device can be manufactured by first creating the first standing portion 51 which is in conjunction with the rear foot portion 45 and the second standing portion 55 which is in conjunction with the front foot portion 41, and then fixing the second standing portion 55 to the first standing portion 51, making it easier to manufacture.

[0078] Otherwise, it produces the same effects and advantages as the fifth embodiment described above.

[0079] [Variation]
