Description

  The present invention relates to a cane auxiliary tool and a cane. More specifically, the present invention relates to a cane auxiliary tool and a cane which are capable of being self-supporting and having excellent stability and handleability when being grounded on the ground or the like.

  A cane is used as a tool for supporting the user's body and assisting walking and the like. The cane generally has an elongated rod-like main body, and a proximal end side is provided with a handle serving as a hand grip, and on the distal end side in contact with the ground, a ground made of rubber or the like for anti-slip A department is provided.

  In addition, when a person who can not walk stably can walk, he / she can support his / her own weight, and as a cane for enabling stable walking, it has multiple contact parts with three or four contact parts at the tip of the cane. Leg-shaped canes are used.

  However, in multi-legged canes, if the ground contact surface is inclined or there is unevenness, the direction of gravity and the axis of the cane will shift, and it will become rather unstable at the time of grounding, so a flat, flat contact surface It is difficult to use outside. In addition, the weight tends to be heavy as compared with the structure in which the single grounding portion is provided, and there is a problem that the burden on the user is increased when long-term use is considered.

  Among these, while the auxiliary leg is opened at the tip of the cane to enable the cane to stand alone, there is a cane structure whose weight is not much different from that of a cane having a single contact portion, for example, Patent Document 1 The staff described in is proposed.

  Here, the cane described in Patent Document 1 is provided with three or more rectangular slits in the axial direction in the lower part of a hollow cane shaft, and is provided with a movable portion and a fixed portion in the slit. Further, auxiliary legs are attached to the movable portion and the fixed portion, and a coil spring is disposed between the movable portion and the fixed portion. Furthermore, a wire is mounted between the movable portion and the locking portion at the top of the wand shaft.

  In the wand described in Patent Document 1, when it is desired to make the wand stand by itself, the wire of the locking portion is loosened, the movable portion moves downward by the tensile force of the coil spring, the auxiliary leg moves away from the slit, and the tip of the wand shaft It can spread and stop as it descends to the lower end of the part, and the cane can stand on its own. Further, by pulling up the wire of the locking portion, the auxiliary leg moves upward, is stored in each slit, and can be used as a normal wand.

Registered utility model No. 3054316

  However, with the wand described in Patent Document 1, processing for providing a large slit on the outer peripheral surface of the existing wand is required, and it takes time and effort to manufacture. In addition, since the slit is formed, the strength of the cane itself is lowered, and there is a possibility that the stability when supporting the weight of the user by touching the ground or the like and the durability of the cane may be impaired.

  In addition, depending on the length of the cane, it may be difficult to manufacture an auxiliary leg in an open state or a form in which the auxiliary leg is folded and stored neatly in the slit so as to have an appropriate size.

  Further, this cane does not have a structure for fixing the auxiliary leg in the open state, and this state is maintained by the tensile force of the coil spring. Therefore, when the support leg is in contact with the tip of the cane and the body is supported while the support leg is open, a force is applied upward from the lower side to the support leg, the movable portion is pushed up, and the support leg closes. There is a possibility that the structure is rather unstable.

  Also, it is conceivable to increase the elastic force of the coil spring in order to stabilize the state in which the auxiliary leg is open, but when storing the auxiliary leg, a strong force is required to pull up the wire of the locking portion It gets worse.

  The present invention has been made in view of the above points, and it is possible to provide a cane auxiliary tool and a cane which are capable of being able to stand on their own and which are excellent in stability and handleability when grounded on the ground or the like. It is the purpose.

  In order to achieve the above object, the cane assisting device of the present invention is positioned with a predetermined distance from the tip of the cane in the longitudinal direction of the stick and protrudes outward from the outer peripheral surface of the cane. A lock piece provided, a through hole through which the cane can be inserted, and a cylindrical leg unit body movable between the lock piece and the tip of the cane, and one end of the leg unit body The other end is configured to be rotatable in a direction toward or away from the wand centering on the one end side, and the leg unit main body is in contact with the lock piece and pushed in the direction of the tip end of the wand In the closed state, the other end is rotated in the direction approaching the wand to be stored, and the leg unit main body is released from the lock piece in the direction of the tip of the wand. The other end is A plurality of legs rotating in a direction away from the wand to form an open configuration, and a cylindrical body attached to the leg unit main body and having a through hole through which the wand and the lock piece can be inserted; The leg unit is configured to be movable in the longitudinal direction of the cane integrally with the leg unit, and is engaged with the lock piece so that the leg unit main body abuts against the lock piece in the direction of the tip of the cane The leg unit main body is positioned on the tip end side of the cane, and the leg supports the cane in a self-supporting manner by being fitted with the storage position groove portion capable of fixing a pressed state and the lock piece. And a holder portion formed on the inner peripheral surface thereof.

  Here, by forming a through hole through which the cane can be inserted in the cylindrical leg unit main body, the cane can be inserted into the through hole, and the leg unit main body can be disposed outside the cane.

  Further, a lock piece is provided at a predetermined distance from the tip end of the wand in the longitudinal direction of the wand, and a through hole through which the wand can be inserted is formed with a lock piece provided to project outward from the outer peripheral surface of the wand. Between the tip and the lock piece in the longitudinal direction of the cane, with the leg unit main body disposed outside the cane by the tubular leg unit body movable between the lock piece and the tip of the cane , The position of the leg unit body can be changed. The predetermined distance referred to here is a position where the leg portion is in an open form and the other end of the leg portion protrudes beyond the tip end portion of the cane with respect to the leg portion integrally moving with the leg unit main body described later. The legs are in the stored form, which means the distance the legs can move (also the distance the leg unit body can move) to the point where the other end of the legs is closer to the lock piece than the tip of the cane .

  Further, the leg portion is configured to be rotatable in a direction in which one end is attached to the leg unit main body and the other end is moved toward or away from the cane about the one end side, whereby the leg portion is substantially parallel to the longitudinal direction of the cane It becomes possible to make it be in the normal orientation (stored form), or to tilt the longitudinal direction of the cane and the leg in a direction forming a certain angle (open form).

  Further, the leg unit body is movable between the lock piece and the tip of the cane, and the plurality of legs are attached to the leg unit body at one end, and the other end is separated from the cane centering on one end side By being configured to be rotatable in a direction, the longitudinal direction of the cane and the legs can be inclined at an angle, so that a plurality of legs can be opened (open configuration) about the cane . Also, with the plurality of legs open, by positioning the leg unit body on the tip end side of the cane, the other end of the legs is grounded to the ground and the canes are supported by the plurality of legs. It can be structured. The structure supporting the cane by the plurality of legs not only enables the cane to stand alone, but also supports the weight of the cane user at the time of grounding.

  Further, the plurality of leg portions are in a state where the leg unit main body is in contact with the lock piece and pushed in the direction of the tip end of the cane, and the other end is rotated in the direction approaching the cane The leg unit body and the lock piece can be brought into contact with each other to close the leg. That is, for example, with the cane held by one hand, the other hand moves the leg unit body along the longitudinal direction of the cane toward the lock piece, and the lock piece and the leg unit body abut And the leg unit body is further pushed in the direction of the lock piece (it can be said that the operation with one hand holding the leg unit body and the other hand pushing the cane in the direction of the leg unit body). It can be closed. That is, the leg can be easily closed and stored only by an operation of moving the leg unit main body along the cane. Also, in this case, since the other end of the leg moves to a position located on the lock piece side from the tip of the cane in the longitudinal direction of the cane, the leg is not opened and only the tip of the cane is grounded The leg portion has a structure that does not disturb walking easily when walking.

  Further, the plurality of leg portions are released by rotating in the direction in which the other end is separated from the wand by releasing the state where the leg unit main body is pushed from the lock piece toward the tip end portion of the wand. The leg can be opened only by an operation of moving the leg unit main body away from the lock piece in the longitudinal direction of the cane. That is, it is possible to easily open the leg only by moving the leg unit body along the cane.

  In addition, the cane and the lock piece are inserted into the through hole by the holder portion being a tubular body attached to the leg unit main body and having the through hole through which the cane and the lock piece can be inserted. In addition, the holder unit can be disposed together with the leg unit body.

  Further, the holder portion is a cylindrical body attached to the leg unit main body and having a through hole through which the cane and the lock piece can be inserted, and is configured to be movable in the longitudinal direction of the cane integrally with the leg unit. By changing the position of the holder unit integrally with the leg unit main body moving between the tip end in the longitudinal direction of the cane and the lock piece, with the leg unit main body and the holder unit arranged by the outside of the cane Can. Also, the user of the cane can hold the holder portion by hand to change the position of the leg unit body and the holder portion in the longitudinal direction of the cane.

  In addition, a storage position groove portion is formed on the inner peripheral surface of the holder portion, which can be engaged with the lock piece to fix the state in which the leg unit body abuts on the lock piece and is pushed in the direction of the tip of the cane. Thus, the lock piece and the storage position groove can be fitted to maintain the position of the leg unit body in the longitudinal direction of the cane in contact with the lock piece and pushed in the direction of the tip of the cane. That is, the other end of the plurality of legs rotates in the direction in which the other end approaches the wand to be in the storage form, and the closed state of the plurality of legs can be fixed.

  Also, a ground position where the leg unit main body is positioned on the tip end side of the cane and the leg supports the cane in a self-supporting manner by being fitted to the lock piece on the inner peripheral surface of the holder portion By forming the groove portion, the lock piece and the grounding position groove portion can be fitted, and the position where the leg unit main body in the longitudinal direction of the cane is located on the tip end side of the cane can be maintained. In the same position, the plurality of legs are in an open state. That is, the other ends of the plurality of legs project beyond the tip of the cane to form an open configuration, and can be fixed in that state. At this time, for example, the cane can stand upright with the cane oriented vertically with respect to the ground or the like and the other ends of the plurality of legs touch the ground. Moreover, the weight of the user of the cane can be supported while the plurality of legs are in the open configuration.

  In addition, when the lock piece and the storage position groove portion or the grounding position groove portion can be fitted by rotating the holder portion about the axis of the cane, only a simple movement for rotating the holder portion The position of the leg unit body in the longitudinal direction of the cane can be fixed. That is, for example, the holder unit is moved to move the leg unit main body with respect to the longitudinal direction of the cane, and the holder unit is easily rotated when located at the storage position of the leg or the ground contact position of the leg. It can be fixed in the storage form of the leg or in the open form.

  In addition, when a guide groove portion communicating with the storage position groove portion and the ground position groove portion is formed on the inner peripheral surface of the holder portion to restrict the rotation of the lock piece about the axial center of the cane, the longitudinal direction of the cane In the above, the movement for moving the leg unit body and the holder portion is guided by the guide groove, and it becomes easy to fit the lock piece into the storage position groove and the ground position groove. That is, it is possible to more easily fix the legs in the stored form or the open form.

  In addition, when the area facing the outer peripheral surface of the cane on one end side of the leg abuts on the outer peripheral surface of the cane, and the rotation in the direction of separating the other end away from the cane is restricted, the leg and the cane The angle formed can be stopped at a predetermined angle. That is, when the legs are open, it is possible to define the degree of opening of the plurality of legs relative to the cane. In addition, when the leg is open and the cane is grounded to the ground and the user's weight is supported by the other end of the leg, the force applied to the leg is in contact with the leg on the outer peripheral surface of the cane. It becomes a structure to receive it. As a result, the stability at the time of grounding on the ground or the like can be improved, and the durability of the wand aid can be enhanced.

  Further, the leg unit main body is provided on the side opposite to the side of the first leg unit member configured to be in contact with the lock piece and the side in contact with the lock piece of the first leg unit member, the first leg unit And a second leg unit member connected to the first leg unit member via an elastic body that biases the first leg unit member disposed between the members toward the lock piece. The first leg unit member is integrated with the second leg unit member via the elastic body. In addition, when the leg unit main body is moved in the longitudinal direction of the cane and the lock piece and the first leg unit member abut against each other and pushed further toward the second leg unit member, the biasing force of the elastic body is resisted. Thus, the distance between the second leg unit member and the first leg unit member can be reduced. Also, by releasing the contact between the lock piece and the first leg unit member, the biasing force of the elastic body makes the distance between the second leg unit member and the first leg unit member constant. Can be returned to the distance. That is, it is possible to reciprocate the first leg unit member so as to move closer to or away from the second leg unit member via the lock piece and the elastic body.

  Further, in the case where the rod is provided with a rod attached at one end to the first leg unit member via the first pin, it is possible to interlock the movement of the first leg unit with the movement of the rod. That is, the rod interlocks with the above-mentioned reciprocation that moves the first leg unit member closer to or away from the second leg unit member via the lock piece and the elastic body.

  In addition, the rod is provided with a rod having one end attached to the first leg unit member via the first pin and the other end rotatably supporting the leg via the second pin; When the second leg unit member is rotatably supported by the second leg unit member via the pin, the first leg unit member, the leg portion and the second leg unit member are connected by the rod. .

  The first leg unit constitutes a slider crank mechanism in which the first leg unit member is a slider, the third pin is an original coaxial, and the region between the second pin and the third pin of the leg is a crank. As the member abuts against the lock piece and the first leg unit member is pushed in the direction of the tip of the cane against the biasing force of the elastic body, the circumference around the third pin is When the second pin moves and the third pin rotates and the other end of the leg rotates in the direction approaching the cane, the leg is released by the reciprocation of the first leg unit member. The form and the storage form can be switched. That is, the leg unit main body is moved in the longitudinal direction of the wand, and the lock piece and the first leg unit member abut against each other, and further pushing toward the second leg unit member or releasing the abutted state This makes it possible to switch between opening and closing the legs. The slider-crank mechanism referred to here is a mechanism that converts reciprocating linear motion into rotational motion.

  In this slider-crank mechanism, the slider on which the first leg unit member reciprocates, the region between the second pin and the third pin of the leg is the crank, and the third pin is the original coaxial. Also, the reciprocating motion of the first leg unit member is transmitted to the third pin through the rod, the first pin, the second pin and the leg (crank), and the third pin is made to be the center of rotation. It changes to rotational movement. The rotational movement about the third pin changes the position of the second pin on the circumference of the rotational movement. At this time, since the third pin itself is also rotated, the leg portion pivotally supported by the third pin is configured to be rotated.

  Further, in order to achieve the above object, the cane of the present invention is formed in a rod shape and has a cane main body provided with a handle at a base end, and a predetermined length from the tip of the cane main body in the longitudinal direction of the cane main body. There is formed a lock piece which is located with a distance and protrudes outward from the outer peripheral surface of the cane main body, and a through hole through which the cane main body can be inserted, and the tip of the lock piece and the cane main body And a cylindrical leg unit body movable between the one end and one end attached to the leg unit body, and the other end is configured to be rotatable in a direction toward or away from the wand body about the one end side At the same time, the leg unit main body abuts against the lock piece and is pushed in the direction of the tip end of the cane main body, whereby the other end is rotated in the direction approaching the cane main body to be stored. And the leg unit body The plurality of legs that are opened in the direction in which the other end is separated from the wand main body by releasing the state where it is pressed from the lock piece in the direction of the tip end of the wand main body; It is a cylindrical body attached to the unit body and formed with a through hole through which the cane body and the lock piece can be inserted, and is configured to be movable in the longitudinal direction of the cane body integrally with the leg unit.

  Further, the upper end of the connection spring 53 is fixed to a spring attachment hole 52b (see FIGS. 2, 3 and 4 (b)) formed in the slider 52, and the leg unit base 55 and the slider 52 is connected. Further, the connection spring 53 biases the slider 52 upward from below to keep the distance between the slider 52 and the leg unit base 55 constant in the vertical direction when no external force is applied to the connection spring 53. It becomes.

  Further, the leg unit base 55 is provided with auxiliary leg attachment grooves 55c in which parts of the leg unit base 55 are cut in the vertical direction at four places in the circumferential direction (see FIG. 5). The auxiliary leg attachment groove 55c is formed in communication with the through hole 55a.

  In the auxiliary leg attachment groove 55c, a part of the upper part of the auxiliary leg 51 and a part of the lower part of the rod 54 are arranged. Further, the auxiliary leg 51 is rotatably attached to the leg unit base 55 via the auxiliary leg pivot pin 63 (see FIG. 3). The auxiliary leg pivot pin 63 mentioned here corresponds to a third pin (original coaxial) in the claims of the present application.

  The auxiliary leg 51 has a pin hole 51a (see FIG. 7) formed at the top. The auxiliary leg pivot pin 63 is located where the pin hole 51a and the pin hole 55d (see FIG. 5) provided on the inner peripheral wall constituting the auxiliary leg attachment groove 55c of the leg unit base 55 are on the same straight line. Is inserted. With this structure, the auxiliary leg 51 is rotatable relative to the leg unit base 55.

See Figure 8). With this structure, the tip end side 520 of the auxiliary leg 51 is in contact with the ground and is supported by the cane main body 2 at a position in contact with the cane main body 2 even when the weight of the user is applied to the auxiliary leg 51 Ru. Thereby, for example, even if the auxiliary leg 51 is formed of a light resin material or the like to reduce the weight, it is difficult to be damaged when a load is applied, and the durability can be improved.

  Here, the upper side surface 510 of the auxiliary leg 51 does not necessarily have to be structured to abut the outer peripheral surface of the wand main body 2. However, as described above, the load applied to the auxiliary leg 51 can be supported by the cane main body 2, and the strength and durability of the entire cane can be enhanced, and a light resin material or the like is adopted for the auxiliary leg 51. It is preferable that the above-described structure be adopted, because the weight of the cane can be reduced.

  The auxiliary leg 51 is provided with a pin hole 51b (see FIG. 7) in the vicinity of the pin hole 51a. The hinge pin 62 (see FIG. 3) is inserted in a place where the pin hole 51b and the pin hole 54a (see FIG. 6) provided in the lower part of the rod 54 are positioned on the same straight line. That is, the auxiliary leg 51 and the rod 54 are connected via the hinge pin 62. The hinge pin 62 referred to here corresponds to a second pin in the claims of the present application. Further, a region between the pin hole 51 a and the pin hole 51 b in the auxiliary leg 51 corresponds to a crank in the claims of the present application. In FIG. 7B, the region corresponding to the crank is shown surrounded by a dotted line indicated by reference numeral 530 (crank portion 530).

Further, the inner circumferential diameter of the pin hole 51 b of the auxiliary leg 51 is formed to be larger than the outer circumferential diameter of the hinge pin 62. By this structure, even if the hinge pin 62 and the pin hole 51b are in contact with each other, the hinge pin 62 smoothly rotates inside the pin hole 51b. Further, the hinge pin 62 does not slide with respect to the pin hole 54a, and the hinge pin 62 and the rod 54 are configured to rotate integrally.

  In the slider 52, a through hole 52a (see FIG. 4) is formed, and the cane main body 2 can be inserted. Further, as described above, the slider 52 is provided with a substantially flat region inside, two of the above-mentioned spring attachment holes 52b are formed in the same portion, and the upper end of the connection spring 53 is fixed.

  Further, in the slider 52, rod attachment grooves 52c are provided at four locations in the circumferential direction, in which a part of the slider 52 is cut away in the vertical direction (see FIG. 4). The rod mounting groove 52c is formed in communication with the through hole 52a.

  In the rod attachment groove 52c, a part of the upper portion of the rod 54 is disposed. In addition, the upper portion of the rod 54 is fixed to the slider 52 via the hinge pin 61 (see FIG. 3). The hinge pin 61 referred to here corresponds to the first pin in the claims of the present application. Moreover, the rod 54 has a shape having a crank shape 54c (see FIG. 6) in part.

  In the slider 52, a pin hole 52d and a pin hole 52e are formed on the wall surface of the rod attachment groove 52c. The hinge pin 61 is inserted where the opposing pin holes 52d and 52e and the pin holes 54b of the rod 54 are positioned on the same straight line. With this structure, the upper portion of the rod 54 is fixed to the slider 52 via the hinge pin 61, and the rod 54 moves integrally with the movement of the slider 52 in the vertical direction.

Further, the slider 52 and the auxiliary leg 51 are connected via the rod 54. Furthermore, the slider 52 and the leg unit base 55 are indirectly connected via the rod 54 and the auxiliary leg 51.

  About the cane 1 demonstrated above, the detail at the time of using the cane auxiliary tool 3 is demonstrated. More specifically, the vertical movement of the wand aid 3, the movement of opening and closing the auxiliary leg 51 interlocked therewith, and the movement of fixing the same will be described.

[Open form of auxiliary leg and fixing at grounded position]
FIG. 8A shows a cross section in a state in which the auxiliary leg 51 is in an open configuration and the tip end side 520 of the auxiliary leg 51 is in contact with the ground to make the wand body 2 stand alone. Further, in this state, the movement of the holder portion 4 and the leg unit 5 in the vertical direction is in a state where the lock piece 23 and the ground position groove portion 42 are restricted by fitting and fixed.

  The state where the lock piece 23 and the grounding position groove portion 42 are fitted is shown in the second drawing from the top of FIG. 9C (a sectional view in the direction of arrow C-C in FIG. 9B). The lock piece 23 and the ground position groove 42 are located in the same direction. Further, the guide groove 41 is formed in a direction in which the ground contact groove 42 is slightly inclined.

  The lock piece 23 can not be rotated in the counterclockwise direction as viewed in FIG. 9C by the contact position groove 42 with respect to rotation around the cane body 2 as a central axis. On the other hand, the lock piece 23 can be rotated from the ground position groove 42 to the shape of the guide groove 41 in the clockwise direction from the state of FIG.

  The lock piece 23 can be rotated by rotating the holder 4 relative to the wand body 2. For example, when the user holds the cane body 2 with one hand and rotates the holder 4 with the other hand, the direction in which the lock piece 23 is fitted with the grounding position groove 42 and the guide groove 41 are fitted. You can switch the matching direction. Further, at this time, the lock piece 23 needs to be positioned at the same height position as the ground position groove 42 in the upper part of the holder 4 in the vertical direction.

  Further, the top view of FIG. 9C is a schematic cross-sectional view of the grounding position groove portion 42, but as shown in the figure, a projection is formed in a region adjacent to the guide groove 41 of the grounding position groove portion 42. The part 42a is provided. The projection 42 a rotates the lock piece 23 in the horizontal direction, and contacts the lock piece 23 when switching between the direction of fitting to the grounding position groove portion 42 and the direction of fitting to the guide groove 41. At the same time, it becomes a resistance that impedes the rotational movement. When the user rotates the lock piece 23 firmly, it can get over the protrusion 42 a and switch the horizontal direction of the lock piece 23.

  The provision of the projection 42 a prevents the lock piece 23 from being rotated by an operation not intended by the user and easily released from the state where the lock piece 23 is fitted and fixed to the grounding position groove 42. be able to. Although not shown, a projection having a similar structure is also provided in the area adjacent to the guide groove 41 of the storage position groove 43.

  When the lock piece 23 is rotated and fitted in the guide groove 41 from the state where the lock piece 23 is fitted in the ground position groove portion 42, the holder 4 and the leg unit with respect to the wand body 2 (lock piece 23) in the vertical direction. It is possible to move 5 downward (see the second figure from the bottom of FIG. 9C).

  Further, in the state where the lock piece 23 is fitted in the ground position groove portion 42, the end 520 of the tip end side of the auxiliary leg 51 protrudes downward from the ground portion 22 of the wand 2 and is grounded to the ground. That is, the contact portion 22 of the wand 2 does not contact the ground, and the wand body 2 is supported only by the end 520 of the auxiliary leg (see FIG. 8A).

  When the end 520 of the auxiliary leg 51 is open, the angle between one auxiliary leg 51 and the cane main body 2 is about 45 degrees, and between the ends 520 of the two opposing auxiliary legs 51. The distance is about 150 mm. Furthermore, as described above, the upper side surface 510 (see FIG. 8A) of the auxiliary leg 51 abuts on the outer peripheral surface of the wand main body 2, and the degree of opening of the end 520 of the auxiliary leg 51 relative to the wand main body 2 is set. The load applied to the auxiliary leg 51 is supported by the cane body 2.

  As described above, the lock piece 23 is fitted in the ground position groove 42 of the holder 4 to restrict the vertical movement of the holder 4 and the leg unit 5 with respect to the cane main body 2. The structure of the walking aid 3 is fixed.

  Even if the weight of the user is supported by the auxiliary leg 51 or the reaction force at the time when the end 520 is grounded to the ground is fixed by the cane auxiliary 3 being fixed at this ground contact position, the auxiliary leg 51 may be applied. , Can stably support the load. Moreover, the cane main body 2 can be stably made independent.

[Opening and closing structure of auxiliary leg by slider crank mechanism]
The slider crank mechanism responsible for switching between opening and closing of the auxiliary leg 51 in the present invention will be described. The main members constituting the slider crank mechanism are the slider 52, the connection spring 53, the leg unit base 55, the rod 54, the auxiliary leg 51 (including the crank area 530), the hinge pin 61, the hinge pin 62 and the like in the leg unit 5 described above. The auxiliary leg pivot pin 63 is provided. In FIG. 8, the structure and the motion of the slider crank mechanism are schematically shown by a solid line and a circle shown by symbol A and a dotted line and a circle shown by symbol B.

  First, the structure in which the slider 52 is connected to the leg unit base 55 by the connection spring 53 enables vertical movement (vertical reciprocation) of the slider 52. In addition, this movement occurs in the vertical direction, and the through hole 52a of the slider 52 and the through hole 55a of the leg unit base 55 are positioned on substantially the same straight line, and the structure through which the cane main body 2 is inserted at that position also contributes. doing.

  In the state where the auxiliary leg 51 is in the open configuration at the ground contact position shown in FIG. 8A, there is no member in contact with the upper portion of the slider 52, and the slider 52 has the leg unit base 55 A constant distance is maintained between them. In this state, the hinge pin 61, the rod 45, the hinge pin 62, the crank portion 530 (area between the pin hole 51a and the pin hole 51b of the auxiliary leg 51), and the auxiliary leg pivot pin 63 (original coaxial) are indicated by symbol A. It is in such a positional relationship.

  Then, from the state shown in FIG. 8A to the position where the storage position groove 43 and the lock piece 23 shown in FIG. Move it.

  Here, the upper end 52 f (see FIGS. 4 and 8B) of the slider 52 abuts on the lock piece 23. Further, when the upper end 52f of the slider 52 is pushed upward on the lock piece 23 side (the lock piece 23 is pushed downward), the force of the pushing operation causes the connection spring 53 to contract against the biasing force of the connection spring 53. The slider 52 moves downward, and the lower region of the slider 52 is accommodated in the through hole 55 a of the leg unit base 55.

  As the connecting spring 53 is contracted and the slider 52 is lowered, the rod 54 connected via the hinge pin 61 is also lowered. As the rod 54 moves downward, the hinge pin 62 is lowered downward along the arc shape with the auxiliary leg turning pin 63 as the original coaxial through the crank 530 (part of the auxiliary leg 51). The auxiliary leg pivot pin 63 rotates with respect to the pin hole 55d together with the downward movement of the hinge pin 62 along the arc. When the auxiliary leg 51 rotates integrally with the rotation of the auxiliary leg pivot pin 63, the end 520 on the tip end side approaches the wand main body 2 to be stored.

  That is, the downward movement of the slider 52 in the vertical direction is converted into a rotational movement by the hinge pin 61, the rod 54, the hinge pin 62, the crank 530 and the auxiliary leg pivot pin 63, and the auxiliary leg 51 is closed by this rotational movement. It is structured to move in the direction (stored form).

  When the upper end 52f of the slider 52 abuts on the lock piece 23 and is released downward, the biasing force of the connection spring 53 causes the slider 52 to move upward and between the leg unit base 55 The distance of returns to a constant state.

  Due to the upward movement of the slider 52 due to the biasing force of the connection spring 53, the auxiliary leg pivot pin 63 rotates in the reverse direction with respect to the pin hole 55d, together with the upward movement of the hinge pin 62 along the arc. Do. The auxiliary leg 51 rotates integrally with the rotation of the auxiliary leg pivot pin 63, and the end 520 on the tip end side is separated from the wand body 2 to be in an open configuration. That is, a motion in the opposite direction to that when the auxiliary leg 51 is in the stored form is generated.

  As described above, the members constituting the leg unit 5 realize the slider crank mechanism that converts the reciprocating motion in the vertical direction into the rotational motion. By this mechanism, the holder portion 4 and the leg unit 5 are moved up and down relative to the wand main body 2 to push the slider 52 downward with the lock piece 23 or to release the contact state, and the auxiliary leg 51 is It is possible to open and close easily.

[Form of storage of auxiliary legs and fixing at storage position]
Further, as described above, the upper end 52f of the slider 52 is brought into contact with the lock piece 23, and the upper end 52f of the slider 52 is pushed upward on the lock piece 23 side (the lock piece 23 is pushed downward). 53 shrinks and the slider 52 descends downward. When the slider 52 descends downward, the lock piece 23 is positioned at a height position where it can be fitted in the storage position groove 43 of the holder 4 in the vertical direction (see FIG. 8B).

  The lock piece 23 is lowered along the guide groove 41 as shown in the bottom view of FIG. 9C (a cross-sectional view in the direction of arrow A-A in FIG. 9B). When the cane body 2 is rotated in the clockwise direction about the cane main body 2 from the height position where it can be fitted in the storage position groove 43, the lock piece 23 is fitted in the storage position groove 43.

  When the lock piece 23 is fitted in the storage position groove portion 43, the movement of the lock piece 23 in the vertical direction at the same position is restricted. As described above, the lock piece 23 is fitted in the storage position groove 43 of the holder 4 to restrict the vertical movement of the holder 4 and the leg unit 5 with respect to the cane main body 2. The structure of the walking aid 3 is fixed.

  By fixing the cane auxiliary tool 3 in this storage position, the auxiliary leg 51 is in a closed storage form, and in the vertical storage position, the end 520 of the tip end side of the auxiliary leg 51 is the ground of the wand 1 It will be located above the part 22 (refer FIG.8 (b) and FIG.9 (a)). That is, since the auxiliary leg 51 is not only closed but also fixed at a position sufficiently away from the ground or the like, it does not disturb the grounding of the wand 1 on the ground portion 22 and is compact. Convenience can be improved.

  As described above, in the first embodiment of the present invention, the lock piece 23 of the cane main body 2 and the cane auxiliary tool 3 that can be externally fitted to the cane main body 2 are provided in the area on the tip side of the cane 1 It is possible to easily change the switching of the ground position or the storage position of the auxiliary leg 51 in the open configuration by using the movement of moving the auxiliary tool 3 up and down with respect to the cane main body 2.

  Further, the auxiliary leg 51 brings the lock piece 23 into contact with the upper end 52f of the slider 52 constituting the wand assisting tool 3 and enables the slider 52 to move up and down by utilizing the biasing force of the connection spring 53. Thus, the vertical movement of the slider 52 can be converted into the opening / closing movement of the auxiliary leg 51. That is, the opening and closing of the auxiliary leg 51 can be switched with a simple operation and a small force for moving the holder 4 and the leg unit 5 up and down to the storage position or the ground position along the longitudinal direction of the wand body 2.

  Furthermore, each position of the holder 4 and the leg unit 5 in the storage position or the ground position in the vertical direction is simply by rotating the holder 4 with respect to the wand main body 2 so that the lock piece 23 can be stored in the storage position groove 43 or the ground position groove 42. Can be fitted and fixed. By fixing the cane auxiliary tool 3 at the storage position and the ground position, it is possible to have a stable structure in a state in which the auxiliary leg 51 is opened and in a state in which the auxiliary leg 51 is closed and stored.

  Moreover, the process with respect to the cane main body 2 is only the operation | work which forms the through-hole which attaches and fixes the lock piece 23, and the cane auxiliary tool 3 can be attached easily. Moreover, since the area | region which processes the cane main body 2 is also small, the intensity | strength of the cane main body 2 itself can fully be ensured.
