Description

  The present invention relates to a cane that can be changed into a chair, and relates to a one-touch openable / closable chair / cane that can be used as a tripod chair by opening a seat and two first and second auxiliary legs with one touch. .

Conventionally, regarding a cane that can be changed into a chair, two of three shaft members made of isometric pipe material are formed with a threaded portion at the outer periphery of one end and a stone butt at the tip portion, and the other end portion. Is provided with a fixed metal fitting with an inner screw. Furthermore, a screw portion is formed on the outer periphery of the other shaft member, and a stone bump is attached to the head of the other end portion. In the middle of the shaft, there is a mounting hole that can be attached to the three-fork member. The shaft is connected and assembled in a rod shape, and the three-fork member is fixed to the top to form a stick. There has been proposed a simple assembling chair that can also be used as a walking stick, which can be constructed by assembling materials with three-pronged members, standing up in a bowl shape on the ground, and fixing a seat to the top (Patent Document) 1).

  When used as a walking stick, the simple assembling chair also has to be reconfigured by reconnecting three equal-length pipe members, and the assembly is time consuming and troublesome. There are challenges. As a cane for solving the problem, the first leg member having a handle on the upper part, the second leg member connected to the first leg member, and the first leg member and the second leg member are supported. A second connecting portion provided on the second leg member is slidably fitted on a spherical outer surface of the first connecting portion provided on the first leg member. The first leg member includes a slide member that is slidable along the first leg member, and prevents the slide member from sliding below the slide member. A second hinge structure provided on the back surface of the seat member, the seat member being pivotably connected to the slide member via the first hinge structure. Via an upper part of the second leg member via a pivot, A first state in which the leg member and the second leg member intersect at the connecting portion, and the sliding member is prevented from sliding downward by the stopper structure, and the first leg member and the second leg There has been proposed a chair characterized in that the slide member changes to a second state in which the slide member rises upward from the first state (Patent Document 2).

  Since the chair supports a person sitting on the stool member by the two leg members of the first leg member and the second leg member, the chair may not be sufficiently stable in the left-right direction when seated, and as a cane When used, there is a problem that the seat member is heavy and may be obstructive. On the other hand, when two rods combined in an X shape with the hinge axis as the center are folded around the hinge axis and can be polymerized, and when the two rods are expanded in the X shape, 2 A portable chair in which the lower side of the hinge axis of the two rods is a leg part and the seat surface part is arranged above the hinge axis, the two rods being above the hinge axis and one on the other side The swing rod is swingably supported at the upper end of the one rod, and there is flexibility between the predetermined position above the hinge shaft of the other rod and the swing rod. The swinging rod is provided with a locking device so that the seat is locked to the one rod at a position where the seat is formed. When the rod is folded and polymerized, the swing rod is also swung and the The cover band is fixed to the rod adjacent to the sheet or the rocking rod at this time, and the cover band can be wound so as to cover the sheet. A portable chair has been proposed (Patent Document 3).

  The portable chair is reduced in weight as a whole because a seat is used instead of the seat member described in Patent Document 2, and when the two rods are polymerized, the seat is folded. Therefore, even if it is compact, there are still two rods that support the person sitting on the seat, so there is a problem that the stability in the left-right direction when sitting is not sufficient. As a chair that solves the problem, three rods are swingably coupled by a hinge part, and can be converted into a state of being folded around the hinge part and a state of being unfolded around the hinge part. The lower part from the hinge part is a leg part, and the seat part is arranged above the hinge part to form a chair. The hinge part includes a first rod and a second rod among the three rods. The third rod can be expanded and deployed with each other sandwiched between the rods, and the first and second rods deployed with each other can be deployed at an angle with respect to a virtual plane passing through each axis. A portable chair characterized by being capable of being proposed has been proposed (Patent Document 4).

  However, in the portable chair shown in Patent Document 4, since the three rod portions are polymerized at the hinge portion, the frictional resistance of the overlapped portion is likely to be generated, and the frictional resistance may be increased. There is a problem that it is sometimes difficult to deploy three rods.

The cane body main leg portion 1 is formed in a hollow pipe shape to accommodate a coil spring 8 that is lightweight and biases the first auxiliary leg portion 4 in the arrow A direction.

  A rod-shaped first auxiliary leg 4 is rotatably provided on the lower side surface of the cane main leg 1 and is openable and closable with respect to the cane main leg 1. When the first auxiliary leg 4 is in an open state with respect to the main cane 1 of the cane main body, the second auxiliary leg 5 described below is surely X-shaped and rotated. The guide tube 6 having a triangular cylindrical shape is inserted into and fixed to the lower peripheral surface of the main cane main leg 1 so that the first auxiliary leg 4 can contact the side surface 6a of the guide tube 6. In a contact state, the cane body main leg portion 1 is provided on the side surface portion so as to be rotatable about a shaft 4a. Of course, the first auxiliary leg 4 may be provided directly on the lower side surface of the cane main leg 1 so as to be rotatable by the shaft 4a without providing the guide tube 6.

  As shown in FIG. 5 and FIG. 6, the guide tube 6 is formed in a regular triangle shape in cross-section, and the cane main leg 1 is inscribed in the guide tube 6. The first auxiliary leg portion 4 is pivotally supported by the shaft 4a at the center portion in the circumferential direction of the side surface 6a of the guide tube 6 and below the center portion in the axial direction. It penetrates the sub-leg 4, penetrates the side 6 a of the guide cylinder 6 and the main cane main leg 1, and is fixed at the apex 6 c facing the side 6 a of the guide cylinder 6. In this embodiment, the guide tube 6 is formed in an equilateral triangle shape. However, when the first auxiliary leg portion 4 and the second auxiliary leg portion 5 are in the open state with respect to the cane body main leg portion 1, an X shape is formed. Of course, as long as the rotation can be performed smoothly, the cross-sectional shape may be other shapes as long as the shape is substantially triangular as a whole.

  The first auxiliary leg 4 has the end of the wire 7 fixed to the upper part of the shaft 4a, and the other end of the wire 7 passes through the communication hole 1a provided in the lower part of the main leg 1 of the cane body, It is fixed in a biased state to a coil spring 8 which is a biasing means fixed to the inside of the lower part of the main body main leg 1. For this reason, the first auxiliary leg 4 is always urged in the direction of arrow A (the opening direction with respect to the cane main leg 1) by the urging force of the coil spring 8, and a force to rotate is applied.

  At the position (the side surface 6b of the guide tube 6 in this embodiment) facing the attachment portion (the side surface 6a of the guide tube 6 in this embodiment) of the first auxiliary leg portion 4 to the main leg 1 of the cane body, there is a rod-like shape. The second auxiliary leg portion 5 is rotatable and is provided so as to be openable and closable with respect to the cane body main leg portion 1. The second auxiliary leg portion 5 is rotatable about a shaft 5a.

  In the present embodiment, like the first auxiliary leg 4, the second auxiliary leg 5 is made to contact the side surface 6b of the guide cylinder 6 via the triangular cylindrical guide cylinder 6 so that the second auxiliary leg 5 can be smoothly rotated. While being in contact, the side surface of the cane body main leg 1 is pivotable about the shaft 5a, but the second auxiliary leg 5 is directly attached to the lower part of the cane body main leg 1 without providing the guide tube 6. Needless to say, the side surface portion may be rotatably provided by the shaft 5a.

  As shown in FIGS. 5 and 6, the second auxiliary leg portion 5 is a central portion in the circumferential direction of the side surface 6b adjacent to the side surface 6a, and is pivotable by the shaft 5a above the central portion in the axial direction. The shaft 5a passes through the second auxiliary leg 5 and passes through the side surface 6b of the guide tube 6 and the main leg 1 of the cane body, and is fixed at the apex portion 6d facing the side surface 6b of the guide tube 6. Has been. Here, the first auxiliary leg 4 is pivotally supported by the shaft 4a below the axial center of the side surface 6a of the guide cylinder 6, whereas the second auxiliary leg 5 is supported by the guide cylinder 6. The side surface 6b of the side surface 6b is pivotally supported by the shaft 5a above the second side leg portion 5 when the first side leg portion 4 is in an open state with respect to the cane body main leg portion 1. Is opened and the second auxiliary leg 5 abuts on the upper part of the first auxiliary leg 4 and the first auxiliary leg 4 and the second auxiliary leg 5 are in an X-shape. is there.

  The second auxiliary leg 5 has a length equivalent to that of the first auxiliary leg 4 but is shorter than the main cane main leg 1, and the first auxiliary leg 4 is energized by the coil spring 7 to generate the cane main body. When in the open state with respect to the main leg 1, as shown in FIG. 1, the second auxiliary leg 5 abuts on the upper part of the first auxiliary leg 4 and the first auxiliary leg 4 and the second auxiliary leg 5 is formed to be X-shaped. For this reason, when the first auxiliary leg 4 tries to rotate in the direction of arrow A by the urging force of the coil spring 8, a force to rotate the second auxiliary leg 5 in the direction of arrow B is applied.

  Further, the end of the wire 9 that is a rotation restricting means is fixed to the lower part of the second sub-leg part 5 from the shaft 5a, and the other end of the wire 9 is fixed to the lower part 1b of the cane body main leg part 1. Yes. For this reason, the second auxiliary leg 5 does not rotate in the opening method (arrow B direction) with respect to the cane main leg 1 beyond the length of the wire 9, and the first auxiliary leg 4 is The rotation of the second counter leg portion 5 is restricted.

  In this embodiment, the end of the wire 10 is fixed to the lower part of the shaft 4a of the first auxiliary leg part 4 just in case, and the other end of the wire 10 is fixed to the lower part 1b of the cane body main leg part 1. The first auxiliary leg 4 is configured so that the first auxiliary leg 4 does not rotate in the opening method (in the direction of arrow A) with respect to the cane body main leg 1 beyond the length of the wire 10. However, even if the wire 10 is not provided, the first auxiliary leg 4 does not rotate more than a predetermined amount by being pressed by the second auxiliary leg 5, and the first auxiliary leg 4 The wire 10 serving as the rotation restricting means is not essential.

  Further, a protrusion 1 c to which a seating sheet 11 that is deformable in a substantially triangular shape is fixed is provided below the grip part 2 of the cane main leg 1, and the seating sheet 11 is provided on the first auxiliary leg 4. The upper end portion, the upper end portion of the second auxiliary leg portion 5 and the projection 1c portion are stretched to form a hammock so that a person can sit on them.

  In FIG. 1, the first auxiliary leg 4 is opened by the coil spring 8 which is a biasing means, and simultaneously, the second auxiliary leg 5 is also pushed by being lifted from below by the first auxiliary leg 4. The second auxiliary leg portion 5 is opened to a predetermined angle by the wire 9 that is the rotation restricting means. In this state, a person can sit on the seating seat portion 11 so that the main leg portion 1 of the cane body is sandwiched between the left and right feet (thighs) and the grip portion 2 is in contact with the chest.

  FIG. 2 shows a state in which the first auxiliary leg 4 and the second auxiliary leg 5 are closed, but the first auxiliary leg 4 and the second auxiliary leg 5 are closed (from the state of FIG. 2), only the second auxiliary leg 5 is rotated in the direction opposite to the arrow B direction in FIG. As a result, the first auxiliary leg 4 is pushed from above by the second auxiliary leg 5 and rotates in the direction opposite to the biasing direction (in the direction of arrow A) by the coil spring 8, resulting in the state of FIG. When the first auxiliary leg 4 and the second auxiliary leg 5 are closed, the first auxiliary leg 4 and the second auxiliary leg 5 are in parallel with the cane main leg 1. Since this state is a state used as a cane, the lower ends of the first auxiliary leg portion 4 and the second auxiliary leg portion 5 are at least the same position as the lower end of the main cane main leg portion 1 or so It is formed to be in the upper position.

  On the other hand, as shown in FIG. 1, a first auxiliary leg portion locking piece 12, which is a first auxiliary leg portion opening prevention means, is provided at the lower portion of the second auxiliary leg portion 5. When the first sub-leg portion 4 and the second sub-leg portion 5 are closed and parallel to the main cane main leg portion 1, the first sub-leg portion locking piece 12 is positioned below the first sub-leg portion 4. Thus, the first auxiliary leg 4 is prevented from rotating again in the opening direction with respect to the cane main leg 1 by the biasing force of the coil spring 8 which is a biasing means. If the first auxiliary leg portion locking piece 12 is not provided below the second auxiliary leg portion 5, the first auxiliary leg portion 4 and the second auxiliary leg portion 5 are connected to the cane main leg 1. When the first auxiliary leg 4 is closed and in a parallel state, the rotation of the first auxiliary leg 4 is not suppressed by the second auxiliary leg 5, so that only the first auxiliary leg 4 is pressed by the urging force of the coil spring 8. It will open to the leg 1.

  By engaging the first auxiliary leg portion locking piece 12 with the lower portion of the first auxiliary leg portion 4, the first auxiliary leg portion 4 and the second auxiliary leg portion 5 are closed with respect to the cane body main leg portion 1. The seated seat portion 11 is also folded and can be used as a cane.

  The operation of engaging the first auxiliary leg portion locking piece 12 with the lower portion of the first auxiliary leg portion 4 is performed by one operation of rotating the second auxiliary leg portion 5 in the direction opposite to the arrow B. Conversely, in order to release the first auxiliary leg portion locking piece 12 from the engagement of the lower portion of the first auxiliary leg portion 4, the second auxiliary leg portion 5 is slightly rotated in the direction of arrow B. When one operation is performed, the first auxiliary leg 4 and the second auxiliary leg 5 are opened with respect to the main leg 1 of the cane body by the urging force of the coil spring 8 which is the urging means. These operations can be performed with a single touch.

  FIG. 3 shows a one-touch openable / closable chair / cane 30 provided with a seating seat storage portion 31 below the grip portion 2 of the main leg portion 1 of the cane body. The seating seat storage portion 31 can be opened and closed by hook-and-loop fasteners 31a and 31b. When used as a chair, the seating seat portion 11 is taken out of the seating seat storage portion 31 to be in the state shown in FIG. 3, and when used as a cane, the first auxiliary leg portion 4 and the second auxiliary leg portion are used. After closing the leg part 5 and making it parallel with the main leg part 1 of the cane body, the seating sheet part 11 is housed in the seating sheet storage part 31 and the hook-and-loop fasteners 31a and 31b are closed to obtain the state shown in FIG. .
