[Embodiment of the invention]

 FIG. 1 shows an example of a cane with a sitting seat to which the present invention is applied. (A) shows the back side of the seat in a closed state, (b) shows the side surface thereof, and (c) shows the side surface of the seat opened state. The cane with a sitting seat includes a main leg 1 in the central portion, side legs 2 and 3 on both sides, a pin 4 as a connecting member, a seat 5 for sitting, a seat locking member 6, a stopper ring 7 as a stopping member, an engaging portion. L-shaped ridge 8 as the above, a coupling piece 9 as the closed position holding means, and the like.

The main leg 1 is provided with a grip portion 1a as a receiving portion that receives a force as a cane on the upper side, and has sufficient strength as a cane and one leg of a stool. The grips 1a may be on both sides of the upper end, or may be simply rounded portions. It may also be located below the upper end. The side legs 2 and 3 are divided in the illustrated example, and are bent lower parts 2a and 3a so as to form a tripod on the lower side together with the main leg 1 and an upper end part 2b for supporting the seat 5 on the upper part. And 3b. Further, in this example, the upper end portion is bent in the horizontal direction, and the end thereof comes into contact with the main leg 1. The legs 1, 2, and 3 can be made of a light metal such as aluminum, wood, bamboo, plastic, or the like, but is preferably a light and strong material. Further, it is desirable that the cross-sectional shape of the circular pipe or the square pipe has a large bending rigidity for its weight.

The pin 4 is provided between the main leg 1 and the side legs 2, 3 between an open state in which a tripod can be formed as shown in (c) and a closed state as shown in (a) and (b). And are connected so that they can be opened and closed. In the closed state, the lower ends 1c, 2c and 3c of the main leg 1 and the side legs 2 and 3 are substantially on the same plane (a plane parallel to the paper surface in the figure). At this time, the lower ends 2c, 3c of the side legs are slightly separated from the installation surface 100 by a distance d when the main leg 1 is upright on the installation surface 100. This distance d varies depending on the length of the cane, the opening angle of the lower portions 2a, 3a, etc., but is determined so that it can be easily used as a cane and a tripod with good balance can be formed with the main leg. Depending on the use and user of the cane, the lower ends 1c, 2c and 3c may be at the same height, or the lower ends 1c may be slightly raised from the installation surface and the legs 2 and 3 may be used as a cane. Can be adopted.

Both ends of the pin 4 are prevented from coming off by caulking or nuts. When the side legs 2 and 3 are separate bodies, each can be freely moved only by the pin 4, so a connecting member 10 for connecting the two is provided as shown by a chain double-dashed line in the figure, and a cane with a sitting seat is provided. The handling may be facilitated.

The seat 5 may be of any size and shape so that a person can easily sit on it, and is made of plastic, light metal, wood or the like. Like the legs, it should be lightweight and strong. In particular, in the case of light metal, the surface may be covered with a soft, heat-retaining and weather-resistant coating material. As shown in FIG. 2A, brackets 11 are erected on the seat 5 at one end side 5a thereof at intervals on both sides in the width direction, and pins 12 are attached between them. .

The seat locking member 6 includes a ring portion 6a that is movably attached to the main leg 1 above the position of the pin 4 and the seat 5 that allows the seat 5 to rotate as shown in FIG. 2A. And a bracket 6b into which the pin 12 is rotatably fitted.

The stopper ring 7 is fixed to the main leg 1 to stop the downward movement of the seat locking member 6, but in this example, the coupling piece 9 is interposed therebetween. This position is related to the length of the side legs 2 and 3, the size of the seat 5, and the like, so that the seat 5 is substantially horizontal when the legs are opened as shown in FIG. 1 (c). . The stopper ring 7 and the main leg 1 may be fixed to each other by any method such as caulking, screwing, or shrink fitting. In the case of screwing, the height and inclination of the seat 5 can be adjusted. In this case, the stopper ring 7 may be prevented from rotating with a set screw.

The L-shaped ridge 8 is provided at the other end side 5 b of the seat 5, and at a position where the seat locking member 6 is stopped by the stopper ring 7, the seat 5 is rotated so that the seat 5 can be seated. The side legs 2 and 3 are engaged with the upper ends 2b and 3b of the side legs 2 and 3 so as to hold the positions thereof. That is, it is formed by side portions 8a that restrain both sides of the upper end portions 2b and 3b and a tip portion 8b that restrains the escape in the opening direction. The side portion 8a may be extended so as to guide the upper end portions 2b and 3b, as shown by a chain double-dashed line in FIG. 1 (a).

As shown in FIG. 1 (c), the L-shaped ridge 8 of this embodiment engages with both sides of the upper end portions 2 b, 3 b and the front end side to restrain the movement in that direction, so that the seat 5 is restrained. When a person sits on the top, the weight of the person sits on the seat 5 and the side legs 2, 3 in a stable state, but when the side legs 2, 3 are moved in the closing direction, the upper end 2b, It can be separated from 3b. As a result, the seat locking member 6 that locks the seat 5 can freely slide on the main leg 1 regardless of the side legs 2 and 3. However, the other end 5b of the seat 5 and the upper ends 2b, 3b of the side legs may be connected to each other so that they can rotate freely.

The connecting piece 9 can hold the main leg 1 and the side legs 2 and 3 in a closed state as shown in FIGS. 1 (a) and 1 (b). That is, as shown in FIG. 2B, a tubular portion 9a fitted into the main leg 1 and capable of moving up and down along with it, is fitted into the side legs 2 and 3 and binds these to the main leg 1. This is a structure in which a downwardly opening groove portion 9b for the above is integrally formed. The lower opening of the groove 9b is narrowed to be slightly smaller than the diameter of the upper ends 2b, 3b of the side legs 2, 3.

In this example, the seat locking member 6 and the connecting piece 9 are shown separately, but this is for the purpose of making the functions of them easy to understand and for the closed position holding means to be the connecting piece 9. This is because various means other than the above can be adopted, and it goes without saying that these may be formed as one body. Therefore, in the example of FIG. 1, the seat locking member 6 may be omitted, the stopper ring 7 may be set at a slightly higher position, and the seat 5 may be joined to the joining piece 9.

The cane with a sitting seat as described above is used in the following manner to exert its action and effect. When used as a cane, the state shown in FIGS. 1 (a) and 1 (b) is set. In addition, in order to make the figure easy to understand, (a) shows a state in which the joining piece 9 is not fitted into the upper end portions 2b, 3b of the side legs and is lifted up, but (b) and FIG. ), The seat locking member 6 and the coupling piece 9 are actually lowered and fitted into the upper end portions 2b and 3b.

In this case, since the groove surface of the groove-like portion 9b of the connecting piece 9 contacts the side surfaces of the upper legs 2b, 3b of the side legs, the fitting between the connecting piece 9 and the side legs should be separated between them. Force does not occur. Therefore, only by slightly narrowing the open side of the groove, the fitting between the joining piece and the side leg is ensured, and the danger of separation of the leg when using the cane is completely prevented. Although the open side of the groove is slightly narrowed, a strong elastic gripping force is not used to connect the legs, so a large force is required when fitting the connecting piece 9 to the side leg. The operation is easy.

By such a connection, the main leg 1 and the side legs 2 and 3 are restrained from moving relative to each other at two portions, that is, the pin 4 portion and the coupling piece 9 portion apart from this, so that the entire It is integrated and all legs can function as a cane. That is, the cane shown in FIGS. 1 (a) and 1 (b) is a three-legged cane, and it is easy to feed the cane according to the progress of walking, and it is a cane that is especially useful for the elderly and people with physical disabilities. In the use as such a cane, only the seat 5 is unnecessary, but since it is small and light, it does not cause much trouble when using the cane. If you are worried about the wobbling of the seat 5, put a torsion spring in the pin 12 to urge the seat 5 to the closing side, or fix the seat to the leg with an appropriate clamp mechanism. You may do it.

In order to change the state from a cane to a stool state, from the state shown in FIGS. 1 (a) and 1 (b), the seat 5 and the seat locking member 6 and the connecting piece 9 are pulled up a little, and the connecting piece 9 is pulled up. The fitting state between the upper ends 2b and 3b of the side legs is released. In this case, since the connecting piece 9 is not tightly fitted to the side leg as described above, the pulling operation is easy.

Next, the seat 5, the seat locking member 6, and the connecting piece 9 are lowered and applied to the stopper ring 7, and the seat 5 and the side legs 2 and 3 are opened to move the seat 5 to the upper end portion 2b of the side leg. Place on top of 3b. When the seat 5 rides on the upper end, the upper end moves with the opening of the side legs, but is stopped and held in position by the side and tip of the L-shaped protrusion 8 of the seat.

As a result, the seat 5 is supported by the main leg 1 on one end side and the side legs 2, 3 on the other end side via the seat locking member 6, the stopper ring 7, etc., and a person is seated on it. As mentioned above, it is in a substantially horizontal and stable support state. Also, in order to improve the function of the cane, it is good to slightly lift the armpit from the installation surface in the closed state, but even if it does so, the length of the cane does not change much, so the main leg and armpit are stable. A tripod is formed. As a result, it becomes a stable stool.

In order to return from the seated state to the cane state, the seat 5, the seat locking member 6 and the connecting piece 9 are pulled up, and the seat 5 and the side legs 2 and 3 are closed to close the legs 1, 2 ,. Align 3 so that they are in the same plane, and lower the connecting piece 9 etc. and fit it on the upper end of the side leg as described above.

As described above, with the cane with a sitting seat according to the present invention, the switching between the cane state and the sitting state can be performed by a simple operation close to one touch. By skillfully adopting and combining all the members, most of the members can be utilized for both cane use and stool use, and at the same time, the improvement of the function as a cane and the securing of a stable state as a stool can be satisfied at the same time. Further, since the tip end side of the seat and the side legs can be separated, the position of the seat 5 when used as a cane can be set to a well-balanced low position as shown by the solid line in FIG. 1 (b). . The two-dot chain line in the figure shows the position of the seat 5 when the front end side of the seat and the side leg are joined so as not to be separated.

FIG. 3 shows an example in which the upper ends 2b, 3b of the side legs 2, 3 on both sides are continuously integrated. Such a structure can be formed by pressing when using an aluminum tube or the like. Further, in order to connect the side legs 2 and 3 to each other, the side legs may be connected by an appropriate joint 13 as shown in FIG. In this way, when the side legs 2 and 3 are integrated, the connecting piece 9 has a shape corresponding to the continuous portion. It should be noted that if the side legs 2 and 3 have an integral structure, the connecting member 10 as shown in FIG. Also, the state of connection with the main landing gear 1 is strengthened.

FIG. 4 shows an example in which the seat 5 is provided with a guide portion for guiding the upper end portions 2b, 3b of the side legs 2, 3. The guide portion (a) is provided with brackets 14 and 15 on one end side 5a and the other end side 5b of the seat 5, a guide rod 16 is attached between them, and the upper end portions 2b and 3b are rotatable respectively. A movable body 17 is provided so that the side legs 2 and 3 can slide along the guide rod 16 in the direction of arrow A via the movable body 17. The guide portion (b) has a structure in which a guide member 18 having a groove 18a is provided in the seat 5, and a slider 17a that fits into the groove 18a is provided at the tip of the moving body 17 on the side legs 2 and 3 side. . The end of the groove 18a is closed by a stopper 18b. According to these guide portions, the upper end portions 2b, 3b of the side legs 2, 3 do not necessarily have to be curved as shown in FIG. That is, the shape may be such that the rod is cut off. Also, it is not necessary for the side legs 2 and 3 to be continuous.

In (c), the guide portion is a guide plate 19, and the upper end portions 2b, 3b of the side legs 2, 3 are directly slidable therein. If the guide portions as described above are provided, the side legs 2, 3 and the seat 5 are integrated, and the switching operation between the cane application and the stool application is further facilitated. Further, in any structure, the bracket 14, the stopper 18b, and the guide plate end 19a engage the side legs 2, 3 and the seat 5 so that the upper end portions 2a, 3a do not separate from the seat 5 when sitting. It also has the function of a mating engaging portion, and has the advantage that the L-shaped protrusion provided on the seat 5 as shown in FIG. 1 can be omitted. On the other hand, in these examples as well, since the upper end portions 2a and 3a are movable with respect to the other end side 5b of the seat 5, the seat 5 can be freely moved independently of the side legs, as shown in FIG. 1 (b). You can lower its position.

FIG. 5 shows another example of the closed position holding means. Actually, the seat 5 is in the vertical direction, but it is illustrated laterally because of the space limitation. The closed position holding means of this example includes a cover portion 20 as a holding portion provided on the seat 5 and a groove member 21 as a seat holding portion attached to the side legs 2 and 3. The cover portion 20 has an upper end portion so as to maintain the space between the upper end portions 2b, 3b of the side leg and the seat 5 when the main leg 1 and the side legs 2, 3 are in the closed position as shown. Hold 2b and 3b in position. The groove member 21 holds the other end side 5b of the seat 5 in position when the main leg and the side leg are in the closed position.

According to such a structure, the seat 5 is integrated with the side legs 2 and 3 on both sides of the one end side 5a and the other end side 5b, so that the main leg 1 and the side legs 2 and 3 are At the position of the side 5a, the seat locking member 6 (FIG. 1 (b)), the seat 5 and the cover 20 are integrated, and the pin 4 is integrated at a position apart from one end side downward. . As a result, the closed positions of the main leg and the side legs are firmly and reliably maintained.

FIG. 6 shows another example of the seat locking member, and is a view of the seat 5 viewed from the back surface side. The seat locking member 6 of this example includes a bracket 6b provided at two positions apart from each other in the direction of arrow B, which is the width direction of the seat 5, two brackets 11 and a pin 12 attached to one end side 5a. It is connected to one end side 5a of the seat 5 through. Note that the brackets and pins may be continuous without separating into two places. With such a structure, it is not necessary to widen the width of the seat 5 on the other end side 5b, and the seat 5 can be formed in a saddle shape such as a spinning wheel as shown in the drawing to have a simple structure. Further, the L-shaped ridge 8 can be integrated, and the side legs 2 and 3 can be simply extended upward. Further, the connecting piece 9 is made into a three-cylinder shape as shown in FIG. 2B to simplify the structure and further improve the easiness and certainty of binding the main leg / side leg. be able to.

Although the above description has been made by taking a normal cane as an example, the present invention can be applied to a special-purpose cane such as a crutch.

[Effect of the invention]

 As described above, according to the present invention, in the device of claim 1, the cane with a sitting seat is provided with a main and side legs, a seat for sitting, a connecting member for connecting the main leg and the side leg so as to be openable and closable, and one end of the seat. A locking member that rotatably locks the side, a stop member that positions the locking member, an engaging portion that engages the other end of the seat and the upper end of the side leg, and the main leg and the side leg are closed. Since the closed position holding means that can be maintained in the state is constituted as the main part, it is possible to effectively utilize these constituent parts to satisfy both the use as a cane and its function and the use as a stool. it can.

That is, in the closed position, the main leg and the side leg can form a three-legged cane. Therefore, as the walking progresses, the landing position of the cane also advances, and the landing position becomes close to the position just below the hand when the cane is worn, and the walking assist function of the cane is improved. In the open position, the main leg and the side legs form a tripod that can support the load of a person sitting on the upper seat. Therefore, all two legs are effectively used. One end of this seat is supported by the main leg by the locking member and the stop member, and the other end is engaged and supported by the upper ends of the side legs by the engaging portion. Can sit down. In this case, it is desirable to form the seat so as to support the seat at three points so that the seat is stable when seated.

Switching between the closed position and the open position is performed by opening and closing between the main leg and the side leg that are openably and closably supported while rotating the seat that is rotatably locked, and keep the closed position at the closed position. This is done by bringing the means into the holding position, releasing it in the open position, and engaging the seat and the side leg with the engaging portion. These operations are easy.

According to the second aspect of the invention, in addition to the above, the engaging portion is detachably engaged with the upper end portion, so that the seat can be freely moved independently of the upper end portions of the side legs. . As a result, the position of the seat can be lowered to improve the balance when walking as a cane. Further, since the upper end portion is released from the seat, this portion can be used for the construction of the closed position holding means, and the structure can be made simple and highly safe.

According to the third aspect of the present invention, in addition to the first aspect of the invention, since the upper ends of the side legs on both sides are continuous and integrated, the operability is further improved. Further, since the side legs are already connected to each other, it is possible to easily and stabilize the binding between the main leg and the side legs.

According to the invention of claim 4, in addition to the invention of claim 2, since a guide portion for accommodating the upper end portion of the side arm is provided in the seat, separation between the seat and the side arm is prevented and operability is improved. The guide part can be used as an engaging part. On the other hand, since the upper end of the side leg can be moved away from the engaging portion, the effect of the invention of claim 2 is retained.

According to a fifth aspect of the present invention, in addition to the first aspect of the invention, a holding portion for maintaining the distance between the upper end of the side leg and the seat in the closed position is provided in the seat, and the seat is provided in the closed position. Since the closed position holding means is formed by providing the seat holding portion for holding the end side to the side leg, the main leg and the side leg can be firmly and reliably integrated via the seat in the closed position. It

In the invention of claim 6, since the seat locking member is coupled to one end side of the seat at positions separated in the width direction of the seat, the seat can be supported at two points on the one end side. Therefore, on the other end side, the seat can be stabilized even if the support interval of the seat is narrowed. As a result, the seat can be formed in a saddle shape, and the shape can be simplified. Further, since the upper ends of the side legs can be brought close to each other, the structure of the closed position holding means can be simplified and the holding state can be further ensured.
