Description

[Technical Field]

[0001] The present invention relates to an uphill walking assist device for assisting walking uphill on a slope. [Background technology]

[0002] Viewing scenery from a high vantage point is one of the joys of traveling. Historical buildings such as shrines and temples are often built on mountaintops and other locations with great views. However, to see these views or shrines and temples, one must climb long slopes and stairs, making it difficult for people with weak muscles to climb on foot.

[0003] For this reason, in recent years, there has been an increasing need for devices that allow climbers to easily walk up slopes, stairs, and inclined ground. In this regard, Japanese Patent Laid-Open Publication No. 61-235259 proposes a rope lift as a device to assist climbers in climbing slopes, etc., in which an endless rope is stretched along a slope at a height suitable for guiding the climber and returns through a tunnel formed below, and this endless rope travels from the lower end of the slope to the higher end at walking speed (Patent Document 1). According to Patent Document 1, by holding on to the endless rope, the climber can easily move up the slope because the endless rope can be pulled by hand. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 61-235259 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the installation of the rope lift described in Patent Document 1 requires digging a tunnel to return the endless rope, which results in high installation costs. Another problem is that the endless rope is difficult to grab because it moves continuously.

[0006] Furthermore, if you trip or are about to fall and try to grab the endless rope to support yourself, the endless rope will continue to move upwards, and you may be dragged along by the endless rope, which could result in serious injury.

[0007] The present invention has been made to solve the above problems, and aims to provide an ascending walking assistance device that is easy to install and allows people to walk uphill easily and safely. [Means for solving the problem]

[0008] The uphill walking assist device of the present invention is an uphill walking assist device that assists walking uphill on a slope, in order to solve the problem of being able to walk uphill easily and safely after installation without requiring large-scale installation work, and comprises a long handrail means that is placed along the slope, and a reciprocating motion means that is connected to the handrail means and moves the handrail means back and forth along the slope at a distance approximately the length of a human stride.

[0009] In addition, as one aspect of the present invention, in order to solve the problem of making the handrail means reciprocate in accordance with the pace of the walker, the handrail means may be composed of a rope, and the reciprocating motion means may be composed of a crank section having the upper end of the rope connected to its tip, and a rotary drive section that supports the base end of the crank section and rotates the tip of the crank section in a circular motion to cause the rope to reciprocate.

[0010] Furthermore, as one aspect of the present invention, in order to solve the problem of accommodating users with different stride lengths, the reciprocating means may be provided with multiple crank portions of different lengths, and the rotation drive portion may be configured to rotate and drive each of the crank portions simultaneously.

[0011] In addition, as one aspect of the present invention, in order to solve the problem of increasing safety by stopping the reciprocating motion when excessive load is applied to the handrail means, the rotational drive unit is composed of an electric motor that generates rotational force and a power transmission mechanism that transmits the rotational force of the electric motor to the crank unit, and the rotational force is transmitted from the electric motor to the power transmission mechanism by frictional force, and the mechanism is configured to slip and stop the reciprocating motion of the rope when a load greater than a predetermined value is applied to the handrail means.

[0012] Furthermore, as one aspect of the present invention, in order to solve the problem of making the handrail means easier to grip and less likely to slip when gripping, the handrail means may be provided with protrusions at intervals of approximately the length of a human stride.

[0013] In addition, as one aspect of the present invention, in order to solve the problem of stopping the reciprocating motion and ensuring safety when excessive load is applied to the handrail means, the handrail means may be composed of a rope, the upper end of which is suspended via a pulley installed at the top of the slope, and the reciprocating motion means may be composed of an upper end weight connected to the end of the rope suspended at the top of the slope, and a lifting means which raises and lowers the upper end weight over a distance approximately the length of a human stride while carrying it.

[0014] In addition, as one aspect of the present invention, in order to solve the problem of reciprocating the handrail means with a simple structure, the handrail means may be composed of a plurality of posts erected at predetermined intervals on the slope, and a long, rod-shaped handrail bar that is erected on each of the posts and supported so as to be able to slide, and the reciprocating motion means may be composed of a cylinder device that extends and retracts the handrail bar by a distance approximately the length of a human stride.

[Figure 5] FIG. 10 is a side view showing another embodiment of an upward walking assist device according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, a first embodiment of an upward walking assist device according to the present invention will be described with reference to the drawings.

[0018] The uphill walking assist device 1 is a device that assists a person in walking up a slope 10 easily and safely, and in this first embodiment, as shown in Fig. 1, it has handrail means 2 that are placed along the slope 10, and reciprocating means 3 that reciprocates the handrail means 2. Each component will be described in detail below.

[0019] The handrail means 2 is for transmitting assist force to the user, and in this first embodiment, is made up of two ropes 21. Each rope 21 is made up of a rope material with ends on both the top and bottom, and is formed to a thickness that allows it to be gripped by hand.

[0020] The diameter of the rope 21 is preferably about 5 mm or more, since if it is too thin it is difficult to grip and may dig into the hand when weight is applied, causing pain, and if it is too thick it is difficult to grip, so a diameter of about 30 mm or less is preferable.

[0021] The rope 21 also has protrusions 22 to improve the anti-slip effect and ease of grip. In this first embodiment, the protrusions 22 are formed by knots in the rope 21, and are formed at intervals approximately equal to a human stride so that they serve as a guide for re-gripping after each step. Specifically, the protrusions 21 on the upper rope 21a are for people with long strides and are formed at intervals of approximately 70 cm, while the protrusions 21 on the lower rope 21b are for people with short strides and are formed at intervals of approximately 60 cm.

[0022] The protrusion 22 is not limited to a knot, but may be formed as appropriate by gluing or bolting a member having a larger diameter than the rope 21 to the rope 21.

[0023] As shown in Fig. 1, each rope 21 is arranged along the slope 10. In this first embodiment, the upper end of each rope 21 is connected to the crank portion 31 of the reciprocating motion means 3 installed at the top of the slope 10, and the ropes are arranged along the slope 10 to the bottom. In this way, there is no need to construct an underground tunnel as in the past to install the ropes 21, so the installation work is easy and the installation cost can be kept low.

[0024] Furthermore, return means 23 is provided at the lower end of each rope 21 to return the rope 21 that has moved upward to its lower position. Return means 23 for the upper rope 21a comprises a weight 23a, which is attached to the lower end of the hanging rope 21 via a pulley 24. The weight of this weight 23a is set to a weight necessary to return the rope 21a to its lower position.

[0025] Returning means 23 for lower rope 21b is made of elastic material 23b and is installed so as to connect the lower end of rope 21b suspended down to the ground via pulley 24. The returning force of elastic material 23b is sufficiently weaker than the force that moves rope 21b upward by reciprocating motion means 3, and is set to a weak force necessary to return rope 21b to the lower position.

[0026] The return means 23 is not an essential component, and if the rope 21 can return to the lower position by its own weight alone, it does not have to be provided on the rope 21 as shown in FIG.

[0027] The reciprocating motion means 3 is used to move the handrail means 2 back and forth along the slope 10, and in this first embodiment, as shown in Figures 1 and 2, it is installed at the top of the slope 10 and is composed of a crank section 31 that connects the rope 21 and a rotational drive section 32 that supports the clamp section 31 and drives it to rotate.

[0028] The crank portion 31 rotates to cause the connected rope 21 to move back and forth. The crank portion 31 in this first embodiment has a length of about half a step, and the upper end of the rope 21 is connected to its tip. In this first embodiment, a bicycle pedal mechanism 311 is provided at the tip of the crank portion 31 to prevent the rope 21 from becoming tangled when the crank portion 31 rotates, and the rope 21 is connected by being fastened to this pedal mechanism 311.

[0029] When the tip of crank 31 rotates in a circular motion, rope 21 moves back and forth within a length range of a human stride, which is said to be about 70 cm to 80 cm for adult men and about 60 cm to 70 cm for adult women.

[0030] In this first embodiment, two crank portions 31a, 31b of different lengths are used, with the upper crank portion 31a being approximately 35 cm long and the lower crank portion 31b being approximately 30 cm long. As a result, the upper crank portion 31a can reciprocate the connected rope 21a at a distance of approximately 70 cm, and the other crank portion 31b can reciprocate the connected rope 21b at a distance of approximately 60 cm.

[0031] 1 and 2, the crank portions 31a, 13b in the first embodiment are disposed at equal intervals of 180 degrees in the rotation direction. This allows the crank portions 31a, 13b to alternately exert assisting force, so that the load of the assisting force from the ropes 21a and 21b is not simultaneously applied to the rotation drive portion 32.

[0032] The number of crank portions 31 is not limited to two, but may be one as shown in FIG. 5, or may be three or more although not shown.

[0033] The rotation drive unit 32 pivotally supports the base end of the crank unit 31 and rotates the crank unit 31. The rotation drive unit 32 in the first embodiment has an electric motor 33 that generates a rotational force, and a power transmission mechanism 34 that transmits the rotational force of the electric motor 33 to the crank unit 31.

[0034] The electric motor 33 is a machine that generates a rotational force by passing an electric current through it, and is a DC motor that can rotate a rotation shaft 331 by connecting it to a battery (not shown) of a car or the like.

[0035] The electric motor 33 is not limited to a DC motor, and an AC motor that can be driven by an AC power source may also be used.

[0036] The power transmission mechanism 34 is a mechanism for transmitting the rotational force exerted by the electric motor 33 to the crank portion 31, and in the first embodiment, utilizes the structure of a bicycle.

[0037] 2, the bicycle comprises a frame 341 corresponding to the bicycle body, a bottom bracket 342 supporting the crank portion 31, a chain wheel 343 that rotates together with the bottom bracket 342, a rear wheel 344 and a rear tire 345 supported by the frame 341, a sprocket 346 fixed to the rear wheel 344, and a chain 347 that connects the chain wheel 343 and the sprocket 346. The frame 341 is supported by a single pipe 348 or the like and is fixed to the ground at the top of the slope 10.

[0038] In the first embodiment, the transmission of rotational force between the electric motor 33 and the power transmission mechanism 34 is performed by frictional force. That is, as shown in Fig. 2, the rotating shaft 331 of the electric motor 33 and the rear wheel tire 345 are in contact with each other and are arranged so that the rotational force is transmitted by frictional force. As a result, when a load greater than a predetermined value is applied to the handrail means 2, the rear wheel tire 345 slips relative to the rotating shaft 331, and the reciprocating motion of the rope 21 stops.

[0039] The power transmission mechanism 34 in the first embodiment is not limited to one that utilizes the structure of a bicycle, but may be selected appropriately from among configurations that appropriately rotate and drive the crank portion 31 using gears or the like.

[0040] Next, the operation of each component of the ascending walking assist device 1 of the first embodiment will be described.

[0041] In the first embodiment, electricity is supplied from a battery to the electric motor 33 to rotate the rotary shaft 331. The rotary shaft 331 transmits the rotational force to the rear wheel tire 345 by frictional force.

[0042] The rotational force received by the rotary shaft 331 from the rear tire 345 rotates the rear wheel 344 and a sprocket 346 fixed to the rear wheel 344. The sprocket 346 rotates the chain wheel 343 and the bottom bracket 342 via a chain 347. The crank unit 31 then rotates together with the bottom bracket 342.

[0043] Crank portion 31 reciprocates rope 21 connected to its tip. Specifically, rope 21a connected to one crank portion 31a rotates so that its upper end traces the path of the tip of crank portion 31a, tracing a circle with a diameter of approximately 70 cm. Rope 21b connected to the other crank portion 31b rotates so that it traces a circle with a diameter of approximately 60 cm.

[0044] As a result, the upper rope 21a moves circularly along the trajectory of the tip of the crank portion 31a, and the entire rope 21a moves back and forth along the slope 10 for a distance of about 70 cm, which corresponds to the length of a human stride. Similarly, the lower rope 21b moves back and forth by the crank portion 31b for a distance of about 60 cm.

[0045] A user who wants to receive assistance for walking uphill grasps the rope 21. In the first embodiment, the rope 21 is arranged along the slope 10, so that the user can grasp the rope from anywhere along the slope 10.

[0046] Each rope 21 moves back and forth at a distance about the length of a human stride, so the user is pulled strongly as the rope 21 moves upward, allowing them to receive a maximum assist force equivalent to about one step. The upper rope 21a is supported at a high position by pulleys 24, making it easy for tall people with large strides to grasp, while the lower rope 21b is supported at a low position by pulleys 24, making it easy for short people with narrow strides to grasp. In addition, each rope 21 has protrusions 22, making it easy to grip and preventing slipping when receiving the assist force, ensuring that the assist force is received reliably.

[0047] Furthermore, when the circular motion of the tip of each crank portion 31 is converted into reciprocating motion, the movement speed of each rope 21 becomes slower, similar to a human walking pace, near the top dead center and bottom dead center (near the highest and lowest positions of the rope 21 in this first embodiment). Therefore, the user can easily match their walking pace with the reciprocating motion of the rope 21.

[0048] If the user takes one step and wants to continue receiving assistive force, he or she moves upward the position where he or she grips rope 21. Protrusions 22 on rope 21 are provided at intervals of approximately the same distance as a human stride, which corresponds to the distance of the reciprocating movement, and therefore serve as a guide when moving the gripping position.

[0049] By appropriately shifting the grip position, the assist force can be obtained step by step when climbing the slope 10, making it easy to climb the slope 10.

[0050] Furthermore, even if a user stumbles and grips the rope 21 tightly to support themselves, the rope 21 only moves back and forth at a distance equivalent to a human stride, so they are not continuously dragged upward. This reduces the risk of injury and allows for safe use.

[0051] Furthermore, in the first embodiment, when a reaction force of a predetermined magnitude or greater is applied to the rope 21, exceeding the frictional force that transmits the rotational force from the rotary shaft 331 of the electric motor 33 to the rear wheel tire 345 of the power transmission mechanism 34, the rotary shaft 331 and the rear wheel tire 345 slip, causing the reciprocating motion of the rope 21 to stop. This makes it possible to further improve safety when an unintended load is applied, and also to prevent breakdown of the device due to an overload.

[0052] Furthermore, each rope 21 that has moved upward can be reliably returned to the lower position by its own weight and the return means 23. The force with which the return means 23 returns the rope 21 to the lower position is sufficiently weak compared to the force pulling the user upward, so there is little risk of the user being pulled downward and falling, and safety is ensured.

[0053] According to the first embodiment described above, the following effects can be achieved. 1. Since there is no need to construct an underground tunnel at the location where the rope 21, which is the handrail means 2, is to be installed, the installation work can be carried out easily and inexpensively, and it can also be installed separately later. 2. By holding the rope 21, one step of assistance can be obtained, and by changing the grip accordingly, assistance can be provided for walking uphill on the slope 10, one step at a time. 3. By converting the rotation of the crank portion 31 into the reciprocating motion of the rope 21, the speed at the start and end of the reciprocating motion is slowed down, making it easier to keep pace with the assisting force. 4. The protrusions 22 on the rope 21 make it easy to grip, provide a non-slip effect, and serve as a guide when changing hands. 5. Since the cranks 31 are provided with two different lengths, the user can select the one that best suits his or her stride length. 6. Even if you grab the rope 21 tightly to support your body when you trip and fall, the rope only moves back and forth at a distance of about a human stride, so you will not be dragged upward and suffer serious injury, and it can be used safely. 7. When a load greater than a predetermined value is applied to the rope 21, the reciprocating motion automatically stops, thereby increasing safety and preventing equipment failure due to overload. 8. The return means 23 can reliably and safely return the rope 21 that has moved upward to its lower position.

[0054] Next, a second embodiment of the uphill walking assist device according to the present invention will be described with reference to the drawings. Note that components that are the same as or correspond to those described in the first embodiment will be assigned the same reference numerals and will not be described again.

[0055] The handrail means 2 is composed of a rope 21. As shown in Fig. 3, the upper end of the rope 21 is wound around a pulley 24 installed at the top of the slope 10 and hangs down. In the second embodiment, the lower end of the rope 21 is also wound around a pulley 24 installed at the bottom of the slope 10 and hangs down.

[0056] The reciprocating means 3 in the second embodiment is composed of an upper end weight 35 connected to the hanging upper end of the rope 21, and an elevating means 36 that raises and lowers the upper end weight 35 while carrying it. In addition, a lower end weight 37 is connected to the hanging lower end of the rope 21 as the returning means 23.

[0057] Upper end weight 35 exerts an assisting force by its weight, which in the second embodiment is set to 30 kg to 40 kg per person depending on the number of people expected to use it at the same time. Upper end weight 35 is placed without being fixed to lifting means 36 in order to stop the reciprocating motion of rope 21 when a force greater than a predetermined value is applied to rope 21.

[0058] The lifting means 36 raises and lowers the upper end weight 35, thereby causing the rope 21 connected to this upper end weight 35 to move back and forth along the slope 10. As shown in Figure 3, the lifting means 36 of the second embodiment is configured as a pantograph-type elevator. This lifting means 36 rises and falls within a height range equivalent to a distance of about a human stride, and the rope 21 moves back and forth following the rising and lowering movement of the upper end weight 35 placed on this lifting means 36.

[0059] The lifting means 36 is not limited to a pantograph type lifting device, but may be appropriately selected from lifting devices using a cylinder device, rack gear, or the like.

[0060] The lower end weight 37 functions as a return means 23 for returning the rope 21 that has moved upward to a lower position. The lower end weight 37 in this second embodiment is formed to be light enough to allow the rope 21 that has moved upward to return to the lower position by its own weight and the weight of the lower end weight 37.

[0061] It should be noted that the return means 23 in the second embodiment is not limited to the lower end weight 37, and may be formed of an elastic material 23a or the like, as in the first embodiment. In addition, if the rope 21 can be returned to the lower position by its own weight, it is not necessary to connect the lower end weight 37 or the like to the lower end of the rope 21.

[0062] Next, the operation of each component of the ascending walking assist device 1 of the second embodiment will be described.

[0063] In the second embodiment, the lifting means 36 raises and lowers the upper end cone 35 at a distance approximately equal to the length of a human stride. At this time, it is preferable to slow the speed near the most elevated position and the speed near the most lowered position to approximately the same as a human stride.

[0064] When the upper weight 35 descends, the connected rope 21 is pulled upward by the weight of the upper weight 35. The user can receive assistance in walking uphill by grasping the rope 21 that is being pulled upward.

[0065] On the other hand, when the lifting means 36 raises the upper end weight 35, the rope 21 returns to the lower position due to its own weight and the weight of the lower end weight 37. At this time, the lower end weight 37 is sufficiently lighter than the upper end weight 35, and the force pulling the user downward is weak, so the risk of falling can be reduced.

[0066] Furthermore, in the second embodiment, the upper end weight 35 is placed on the lifting means 36 without being fixed, so when a load greater than a predetermined value is applied to the rope 21, the upper end weight 35 separates from the lifting means 36, and the rope 21 stops moving upward any further and stops reciprocating. Therefore, as in the first embodiment, it is possible to improve safety when an unintended load is applied, and also to prevent breakdown of the device due to an overload.

[0067] As described above, according to the ascending walking assist device 1 of the second embodiment, the upper end weight 35, the lifting means 36, and the lower end weight 37 as the reciprocating means 3 can provide the same effects as those of the first embodiment.

[0068] Next, a third embodiment of the uphill walking assist device according to the present invention will be described with reference to the drawings. Note that components that are the same as or correspond to those described in the first and second embodiments will be assigned the same reference numerals and will not be described again.

[0069] As shown in Figure 4, the handrail means 2 in this third embodiment is composed of multiple posts 25 erected on the slope 10 and long, rod-shaped handrail bars 26 installed on each post 25.

[0070] The posts 25 are for supporting the handrail bar 26 so that it can slide along the slope 10, and in this third embodiment, each post 25 is provided with a ring-shaped support ring 251 with an inner diameter large enough to insert the handrail bar 26, at a height of 75 cm to 85 cm from the ground, which is the height of a typical handrail. In this third embodiment, five or so posts 25 are erected at equal intervals on the slope 10, as shown in Fig. 4.

[0071] The number and spacing of the posts 25 are not particularly limited, and may be selected appropriately depending on the length of the slope 10, the number of posts required to support the handrail bars 26, etc.

[0072] The handrail bar 26 is a long rod-shaped member for transmitting assistive force to the user, and like the rope 21 in the first and second embodiments, is formed to a thickness that can be held in the hand.

[0073] As shown in Figure 4, the handrail bar 26 in this third embodiment is installed by inserting it into the support rings 251 of each support post 25 erected on the slope 10, and is supported so that it can slide along the slope 10.

[0074] The reciprocating motion means 3 in this third embodiment reciprocates the handrail bar 26, which is supported so that it can slide along the slope 10, and is composed of a cylinder device 38 that can extend and retract over a distance approximately equal to the length of a human stride.

[0075] The cylinder device 38 is a device for reciprocating the handrail bar 26, and in this third embodiment, as shown in Figure 4, is composed of a hydraulic cylinder 381 and a connecting member 382 that connects this hydraulic cylinder 381 to the handrail bar 26.

[0076] The hydraulic cylinder 381 is extended and retracted by hydraulic pressure and is fixed to the top support 25 so that the extension direction is parallel to the sliding direction of the handrail bar 26. Although not shown, the hydraulic cylinder 381 is connected to a hydraulic pump, and is configured so that the speed, extension distance, etc. can be appropriately controlled.

[0077] The connecting member 382 transmits the expansion and contraction force of the hydraulic cylinder 381 to the handrail bar 26 to cause the handrail bar 26 to move back and forth, and connects and fixes the hydraulic cylinder 381 and the handrail bar 26 together.

[0078] The cylinder device 38 is not limited to one using the hydraulic cylinder 381, but may be appropriately selected from a pneumatic cylinder, an electric cylinder (electric actuator), or the like.

[0079] Next, the operation of each component of the upward walking assist device 1 of the third embodiment will be described.

[0080] Hydraulic cylinder 381 receives hydraulic pressure from the hydraulic pump and expands and contracts at a distance roughly equivalent to a human stride. The expansion and contraction of hydraulic cylinder 381 is transmitted to handrail bar 26 via connecting member 382, ​​causing reciprocating motion of handrail bar 26. It is preferable to control the speed near the most extended position and the speed near the most retracted position so that they are roughly the same speed as a human stride.

[0081] The handrail bar 26 moves back and forth at a distance approximately equal to a human stride as the hydraulic cylinder 381 expands and contracts. A user who wishes to receive assistance in walking uphill grasps the handrail bar 26. The handrail bar 26 in this third embodiment is supported at about the same height as a typical handrail, making it easy for the user to grip.

[0082] When the handrail bar 26 moves upward, the user is pulled strongly and receives an assistive force equivalent to approximately one step. If the user wishes to receive an assistive force continuously, the user can move forward one step at a time by switching grips as needed.

[0083] As described above, according to the uphill walking assist device 1 of the third embodiment, it is possible to obtain the same effects as those of the first and second embodiments.

[0084] The uphill walking assist device according to the present invention is not limited to the above-described embodiments and can be modified as appropriate. For example, the installation position of the reciprocating means 3 is not limited to the top of the slope 10, but may be installed midway along the slope 10 or on multiple slopes.

[0085] Furthermore, the slope 10 on which the upward walking assist device 1 is installed is not limited to a slope, but may be a stepped one as shown in Fig. 5. In this case, it is preferable that the distance over which the handrail means 2 is reciprocated is matched to the stride length based on the step height of the stairs. [Explanation of symbols]
