Description

  The present invention relates to a cane.

  Conventionally, there is a cane composed of four self-supporting columns (see, for example, Patent Document 1).

  However, although the conventional cane can stand independently, it can not be received in a stable posture when the direction of action of the force applied to the cane by the user is slightly offset or inclined with respect to the axial direction of the column. In some cases, there was a problem with stability. In particular, when the ground is uneven, the stability problem is significant because the four columns can not simultaneously touch the ground and can not receive a well-balanced reaction force from the ground.

First Embodiment
Hereinafter, a first embodiment for carrying out the present invention (hereinafter, referred to as “first embodiment”) will be described in detail based on the attached drawings.

  FIG. 1 shows three elevations of the wand according to the first embodiment, FIG. 1 (a) is a front view, FIG. 1 (b) is a plan view, FIG. 1 (c) is a right side view, and FIG. It is a perspective view. 1 (a) and 1 (c) show a state in which the cane 100 is in contact with the ground G at the lower three points of each leg and becomes independent. Note that the upper side in FIG. 1 (b) and the right side in FIG. 1 (c) are respectively referred to as the front, and the lower side in FIG. 1 (b) and the left side in FIG. Let each be called the back.

  As shown in FIGS. 1 (a), 1 (b), 1 (c) and 1 (d), the cane 100 according to the first embodiment branches from the head 40 and the head 40. And a leg having a grounding portion at its lower end that is suspended and contacts the ground G. The legs are comprised of a first leg 10, a second leg 20 and a third leg 30. Thus, there are three legs. Therefore, even if the ground G is uneven, since the lower three points of each leg (the first leg 10, the second leg 20 and the third leg 30) are in contact with the ground G, the head 40 can be Stable and supportable. Therefore, even if a force acts on the cane 100 by the user leaning on the cane 100, a reaction force can be appropriately transmitted to the user by the minimum number of legs. And the cane 100 can support a user firmly without falling, and its stability is high.

  Moreover, the center of gravity of the wand 100 is set so that it can stand in a state where the lower three points of each leg are in contact with the ground G. Thereby, the cane 100 can be in a stable state even when not in use.

  The lower end of the first leg 10 is provided forward of the lower end of the second leg 20 and the lower end of the third leg 30. Thereby, even if the user leans forward and the force directed diagonally forward acts on the upper end of the first leg 10, the lower end of the second leg 20 and the lower end of the third leg 30 are connected. Since the first leg 10 resists the force of the entire cane 100 to rotate forward about the line, the cane 100 can firmly support the user without falling over and has high stability.

  As shown in FIG. 1C, the first leg 10 is inclined forward at a predetermined angle α in a side view. Thereby, even if the user leans forward and the force directed diagonally forward acts on the upper end of the first leg 10, the direction of the force and the upper end of the first leg 10 and the first leg 10 Since the deviation between the lower end and the lower end is reduced, the cane 100 can support the user firmly without falling, and the stability is high.

  Further, the angle α inclined forward of the first leg 10 is larger than the angle β inclined rearward of the second leg 20 and the third leg 30. As a result, even if the user places weight on the cane 100 from the top to the rear as if the user stopped at the place without walking, the second leg 20 and the third leg 30 are mainly Since the force acts in the axial direction, the moment acting between the head 40 and the second leg 20 and the third leg 30 is reduced, so that the deformation of the wand 100 can be suppressed and the user can be supported firmly. If the weight is directed obliquely downward toward the cane 100 as when the user is walking, a force acts mainly on the first leg 10 in the axial direction, so the head 40 The bending moment acting between the first leg 10 and the first leg 10 is reduced, the deformation of the wand 100 is suppressed, the user can be firmly supported, and the stability is high.

  The head portion 40 includes a horizontal portion 41 extending substantially horizontally, and a handle portion provided with a first inclined portion 42 and a second inclined portion 43 continuously extending so as to incline rearward and downward from both sides of the horizontal portion 41. Have. Since the head 40 has the horizontal portion 41 as a handle portion, even if the user leans forward while holding the horizontal portion 41 with his hand, the user's hand is turned substantially vertically from the horizontal portion 41. The hand is hard to slip because the power is transmitted. As a result, the cane 100 can support the user firmly. Similarly, the head 40 has the first inclined portion 42 and the second inclined portion 43 as a handle portion, so that the user holds the first inclined portion 42 and the second inclined portion 43 forward with the hand. Even if the user leans on the hand, since the reaction force is transmitted to the hand of the user substantially perpendicularly from the first inclined portion 42 and the second inclined portion 43, the hand does not slip easily. As a result, the cane 100 can firmly support the user and has high stability.

  The first leg 10 continues to the horizontal portion 41. Thereby, since the rigidity of the horizontal portion 41 is increased, even if a force directly acts on the horizontal portion 41 by the user, the force can be transmitted to the first leg 10, and the displacement of the horizontal portion 41 is suppressed. Be That is, even if a force is applied to the horizontal portion 41, the first leg 10 is stretched by receiving a reaction force from the ground G, and hence the position of the horizontal portion 41 hardly changes. As a result, the cane 100 can firmly support the user and has high stability.

The second leg 20 and the third leg 30 respectively continue to the lower ends of the first inclined portion 42 and the second inclined portion 43. Thereby, the second leg 20 and the third leg 30 and the first inclined portion 42 and the second inclined portion 43 can be integrally formed by bending the rod material or the pipe material. The second leg 20 and the third leg 30, the first inclined portion 42 and the second inclined portion 43, and the horizontal portion 41 may be integrally formed. Thereby, it can shape | mold easily by bending-processing a rod material and a pipe material. The head 40, the first leg 10, the second leg 20, and the third leg 30 are separately provided, and the cane 100 is placed on the head 40 with the first leg 10, the second leg, and the like. The 20 and the third leg 30 may be fitted separately to provide a structure that can be assembled.
Transition portions from the lower ends of the first inclined portion 42 and the second inclined portion 43 to the second leg 20 and the third leg 30 are curved and smoothly connected. As a result, even if the user holds the transition portion by hand, the cane 100 is easy to hold since the reaction force is not concentrated on a part of the hand and dispersed.

  The cane 100 has a symmetrical shape in plan view, as shown in FIG. 1 (b). Thus, the cane 100 can support the user in a well-balanced manner, regardless of whether the user applies a force to the lower left or the lower right. Thus, for example, the user holds the first inclined portion 42 with the left hand and at the same time holds the second inclined portion 43 with the right hand, so that the cane 100 can be used even when walking while holding the cane 100 with both hands. Support people with disabilities.

Second Embodiment
Next, a second embodiment for carrying out the present invention (hereinafter, referred to as “second embodiment”) will be described in detail based on the attached drawings.

2 (a) is a front view, FIG. 2 (b) is a plan view, FIG. 2 (c) is a right side view, and FIG. 2 (d) is a three side view of the wand according to the second embodiment. It is a perspective view. 2 (a) and 2 (c) show a state where the cane 100 is in contact with the ground G at the lower three points of each leg and becomes independent. Unless otherwise described, the upper side in FIG. 2 (b) and the right side in FIG. 2 (c) are respectively referred to as the front, and the lower side in FIG. 2 (b) and the left side in FIG. 2 (c) Let each be called the back.
The difference between the first embodiment and the second embodiment is the configuration of the head 40, so the head 40 will be mainly described below, and the description of the common parts may be omitted.

  As shown in FIGS. 2 (a), 2 (b), 2 (c) and 2 (d), the cane 100 according to the second embodiment is similar to the cane 100 according to the first embodiment, It has a head 40 and a leg which is branched from the head 40 and descends and has a contact portion at its lower end that contacts the ground G. The legs are comprised of a first leg 10, a second leg 20 and a third leg 30. Thus, three legs are provided like the cane 100 according to the first embodiment.

  Further, the head 40 is, similarly to the wand 100 according to the first embodiment, a horizontal portion 41 extending substantially horizontally, and a first inclined portion 42 extending continuously in a row from the both sides of the horizontal portion 41 so as to incline rearward and downward. And the handle portion provided with the second inclined portion 43.

Here, the head portion 40 of the cane 100 according to the second embodiment has a stiffening portion 44 separate from the handle portion. As shown in FIG. 2B, the stiffening portion 44 has substantially the same shape as the handle portion in plan view, and is parallel to the ground G so as to be along the horizontal surface, in other words, It is arranged. The stiffening portion 44 welds or separates the first transition portion between the first inclined portion 42 and the leg portion 20 and the transition portion between the second inclined portion 43 and the second leg portion 30, for example. It may be connected and integrated, or may be integrated by fitting one of the stiffening portion 44 and the transition portion to the other.
As a result, since the rigidity of the entire cane 100 is increased and it becomes difficult to deform as compared to the cane 100 according to the first embodiment in which the legs are directly connected to the handle, the cane 100 supports the user firmly. it can.

  Also, the first leg 10 is connected to the stiffening portion 44. Thereby, the rigidity of the entire cane 100 can be enhanced, and the user can easily hold the handle because the first leg 10 is not connected to the handle. Further, the handle portion is cantilevered on the upper ends of the second leg portion 20 and the third leg portion 30, and is easily elastically deformed in the direction indicated by the white arrow in FIG. 2C. When a person applies a force to the lower front while holding the handle, the force can be absorbed by the elasticity of the handle. Therefore, in particular, when the user walks, it is assumed that landing on the ground G from the state where the cane 100 is lifted from the ground G is repeated, but relieving the impact on the user from the wand 100 at the time of landing. Thus, the cane 100 can be made less tired even if the user uses it for a long time.

Although the present invention has been described above using the embodiment, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiment. It is apparent to those skilled in the art that various changes or modifications can be added to the above embodiment. It is also apparent from the scope of the claims that the embodiments added with such alterations or improvements can be included in the technical scope of the present invention.
For example, a cushioning material may be provided at the lower end of the leg. As a result, effects such as shock absorption, anti-slip, and muffling effect can be obtained.

  The cane 100 of the present invention includes a head 40 and a leg which is branched from the head 40 and descended and has a ground contact portion at the lower end which contacts the ground G, and there are three legs. It is possible to support the user firmly without having a high stability.
