Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a cane that can be used as a seat with a foldable seat part that can be used as a seat with simple operation.

[Conventional technology]

Conventionally, as a walking stick with a foldable seat that can be used as a seat, the walking stick part has a pair of vertically extending support plates, such as the cane with chair of Utility Model Application Publication No. 59-194821, and a plate serving as a chair part is used. The proximal end of the cane is pivoted to perform folding or unfolding operations, or the cane with a removable seat of Utility Model Publication No. 49-21052 can be folded into a cylindrical body that is slidably inserted into the cane. A structure in which a seat is attached to the seat is known. However, in the above-mentioned known structure, since the cane chair part is pivoted and folded by pivoting up and down, a locking structure is required when unfolding, which complicates the structure and does not provide sufficient strength when used as a chair. However, if the strength is increased, the weight increases. In addition, in the latter case, the cylindrical body with the seat attached is simply slidably attached to the cane and the cane is tilted for use. In this situation, there is a risk that the barrel may slide off the cane and fall off. Furthermore, when both are used as a seat, the position of the seat is fixed and tilts in conjunction with the slight movement of the cane, resulting in poor sitting comfort.

[Problem that the invention attempts to solve]

This idea was devised as a result of intensive research in view of the above circumstances, and the main problem was that the seat part could be folded with a simple structure, and the cane would not move when used as a seat. The purpose of the seat part is to provide a highly stable cane that can be adjusted to fit along the body at all times.

[Means to solve the problem]

This invention solves the above-mentioned problems by (a) providing a hole in the middle of the stick that is inclined with respect to the axis of the stick and opening at least on one side; (b) providing a hole in the hole. The proximal end is rotatably inserted and the part protruding outward from the hole is bent in a direction substantially perpendicular to the axis of the stick, so that the folded position is parallel to the stick and the stick is approximately parallel to the stick. (c) providing a means for preventing the rotating arm from falling off the stick; (d) providing a seat portion on the protruding side of the rotating arm; We are taking technical measures to form

[Effect]

The base end side of the rotating arm is fitted and inserted at an angle with respect to the axis of the stick, and the protruding side that protrudes outward is bent and extends in a direction substantially perpendicular to the axis of the stick. When the base end side of the rotary arm rotates, the protruding side can be displaced from a folded position parallel to the stick rod to an expanded position substantially perpendicular to the stick stick. Since a seat is formed on the protruding side of this rotating arm, it can be used as a seat in the unfolded position. In this case, the rotation arm is not restricted in its rotation in the deployed position, so it rotates slightly in response to the slight displacement of the user's center of gravity or the wobbling of the stick, and adjusts the angle to fit the user's body. adjusted to. Furthermore, when used as a cane, the seat can be folded up and out of the way by inverting the rotating arm to the folded position. In addition, since the rotating arm is engaged with the stick rod by means for preventing it from falling off, the seat portion will not fall off.

【Example】

Below, preferred embodiments of the cane that also serves as a seat will be described based on the drawings. Walking stick 1 shown in Figures 1 to 4
is the stick stick 2 and the hole 3 that opens in the middle of the stick stick 2.
and the rotating arm 4 and the stick stick 2 of the rotating arm 4.
It is comprised of a retaining means 5 for preventing the arm from falling off, and a seat portion 6 formed on the rotating arm 4. That is, in the case of this embodiment, the stick stick 2 includes a stick stick main body 21 made of reinforced wood with a slightly swollen middle part, and a stone protrusion 22 that is fitted onto the lower end of the stick stick body 21 and has an uneven pattern on the ground surface. It consists of a grip 23 formed at the upper end. And in the middle part of the stick stick main body 21,
A hole 3 is provided which is formed obliquely to the axis 1 of the stick rod 2 and is open at one end. In this embodiment, the hole 3 is bored at an angle of about 45 degrees downward with respect to the axis l of the stick stick 2, and a plastic plate is provided inside the hole 3 to cover the inner peripheral wall surface. A bush 31 is installed inside, which lubricates the rotational movement of the rotating arm 4 (described later), and also allows the stick body 21 to be attached to the opening edge of the hole 3.
This prevents the material from sticking up. A base end side of a rotating arm 4 is rotatably fitted into this hole 3. That is, the rotating arm 4 is made of steel, and the base end 4a is inclined at approximately 45 degrees along the inclination of the hole 3, and the other end 4b (which is the protruding side) is horizontal. It consists of an extending shape. A long elliptical flange 41 is fixed to the protruding side 4b of the rotating arm 4, and a disk-shaped seat 6 is fixed to the flange 41 via screws or the like. The material and shape of this seat part 6 are not particularly limited, as long as the user can sit on it, and the seat part 6 is configured to be fixed to a separate part from the rotating arm 4. Alternatively, the protruding side of the rotating arm 4 may form a series of seat parts 6 on which the user can sit. For example, the protruding side 4b of the rotating arm 4 may be formed into an annular shape, and a net may be stretched thereon to form the seat portion 6. The rotating arm 4 has the above-mentioned curved shape, and its base end 4a is rotatably inserted into the hole 3, so that it is in a folded position parallel to the stick stick 2. (See FIG. 4) and a deployed position (see FIG. 2) that is substantially perpendicular to the stick rod 2. Further, on the base end side 4a of the rotating arm 4, an annular groove 5a is formed in the circumferential direction on the outer periphery of the shaft. On the other hand, on the back side of the hole 3 of the stick rod 2, a locking pin 5b that always abuts a part of the groove 5a is fixedly provided so as to pass through the stick rod 2 in the lateral direction. As a result, the rotating arm 4 can rotate within the hole 3, and the locking pin 5b fixed to the stick rod 2 is always locked in a part of the groove 5a of the rotating arm 4. , prevents the rotating arm 4 from falling off. That is, in this embodiment, the retaining means 5 has a configuration of the concave groove 5a of the rotating arm 4 and the locking pin 5b, but the retaining means 5 of the present invention is not limited to the above configuration.
For example, the proximal end 4a of the rotating arm 4 is attached to the stick stick 2.
A locking flange having a diameter larger than the hole on the opposite side penetrates through the hole to prevent the rotating arm 4 from falling out, or a protrusion is formed in an annular shape instead of a concave groove on the base end 4a of the rotating arm 4. In other words, the rotating arm 4 can be rotated around the stick rod 2 and moved in the axial direction, such as by forming a groove in the hole that protrudes and engages with the protrusion to prevent it from falling off. If so, any configuration that restricts movement in the falling direction may be sufficient. In addition, on the back side of the seat part 6, there is an engaging part 7 for hooking on the stick stick 2 when the seat part 6 is folded.
It is preferable to provide In the illustrated example, the engaging portion 7 has a concave portion 7a corresponding to the curvature of the outer circumferential surface of the stick rod 2 at the center of the bottom surface, and a rounded guide surface 7b that gradually becomes thinner on the sides. (See Fig. 3) To explain how to use this cane 1 that also serves as a seat, with reference to Figs. 5 and 6, first, when the seat part 6 is folded as shown in Fig. concave groove 5
When a is removed from the peripheral wall of the stick stick 2 and the rotating arm 4 is rotated downward via the seat 6, the protruding side 4b of the rotating arm 4 is displaced from the vertical position to the horizontal position as shown in FIG. . In this state, as shown in FIG.
Sit on it and use it as a stool. At this time, the grip 23 may be held by the user as shown in the illustrated example to improve stability as a seat, but as shown in FIG. It is preferable that the grip 23 be placed in the seat and the grip 23 be used like a back support when sitting. In this case, stability will be further improved if both feet are supported at two points in front of the body and the cane stick 2 is placed at the apex of the isosceles triangle formed by the two points. suitable. When used as a seat, the rotating arm 4 is not restricted in its rotation at the unfolded position as described above, so even if the user's center of gravity shifts slightly or the stick becomes unsteady. However, the seat part 6 does not interlock with the cane stick 2 to maintain a predetermined angle, but rotates in the direction in which the load is applied in response to the above displacement, so the seat part 6 is always adjusted to an angle that fits the body. This is suitable. After use as a seat, when the rotating arm 4 is rotated upward in the reverse direction, the protruding side 4b of the rotating arm 4 is displaced from a substantially horizontal position to a vertical position. Then, the concave groove 5 is inserted through the guide surface 7b of the engaging portion 7.
A is inserted into the outer periphery of the stick stick 2, and the seat part 6 is removably hooked to the stick stick 2 as shown in FIG. 3, so that the user can use it as a stick as shown in FIG. . In this embodiment, the folding position of the rotating arm is exemplified as rotating upward relative to the unfolded position. This is preferable because when using it as a stick, the center of gravity is located above the stick, making it easier to operate. However, in the present invention, it is of course possible to adopt a configuration in which the rotating arm is rotated downward and displaced to the folding position.

[Effect of the idea]

Since this invention has the above-mentioned configuration, folding and unfolding operations can be performed by rotating the rotating arm, and the folding mechanism can be extremely simplified. Further, when the seat is used as a seat, even if the user's body moves or the stick stick becomes unstable, the seat is always adjusted to a position that fits the user's body, providing good sitting comfort. Furthermore, since the structure can be simplified and the weight can be reduced, there is no problem in using it as a walking stick.
Furthermore, since the number of component parts is small and the production process can be labor-saving, productivity can be increased, which is advantageous.
