  Each support 20 has a double-cylinder structure having an inner rod 21 on which the leaning member 1 is attached at the upper part, and a fixed outer cylinder 22 into which the inner rod 21 is slidably inserted up and down. , So that it can be expanded and contracted up and down. Further, the pair of support portions 20, 20 is configured to be freely adjustable in height (positionable).

  In the stepless height adjustment structure, a screw hole in the radial direction is formed in the upper part of one outer cylindrical portion 22, and a lever-type operating member 26 having a bolt portion screwed into the screw hole is screwed. I'm wearing When the operating member 26 is operated in one direction of rotation and screwed, the end surface of the bolt portion comes into pressure contact with the outer surface of the one inner rod portion 21, and the inner rod portion 21 itself comes into pressure contact with the inner peripheral surface of the outer cylindrical portion 22. Then, the pair of inner rod portions 21 and 21 is prevented from sliding vertically (positioned). When the operating member 26 is rotated in the other direction and screwed away, the end surface of the bolt portion is separated from the outer surface of the one inner rod portion 21 so that the pair of inner rod portions 21 and 21 can slide up and down. Become. That is, the vertical position of the inner rod portion 21 is determined by the friction caused by the pressure contact, so that the height can be adjusted steplessly.

  The lower end of each support 20 is formed in an inverted T-shape in side view having a front-rear horizontal front protrusion 20d and a front-rear horizontal rear protrusion 20e. In other words, the support member 2 is formed in an H shape in plan view.

The lateral width of the footboard 30 is formed in a trapezoidal shape or a fan shape in a plan view so as to decrease toward the rear (the lower end of the support member 2) in the deployed state. In other words, a pair of left and right side edges of the footboard portion 30 are arranged in a V shape that approaches each other rearward (separates forward from each other).

  The swinging rod member 31 has an L-shape in a side view, and is disposed at the right and left outer positions of the support member 2 (the pair of support portions 20, 20). The swinging rod member 31 is pivotally attached to the lower portion of the support portion 20 and has a base end portion 31a which is in a vertical posture in a deployed state, and a front protruding portion 20d of the support portion 20 extending horizontally horizontally from the base end portion 31a. It has an intermediate portion 31b disposed in parallel, and an arm portion 31c that is inclined forward and left outward from the intermediate portion 31b in a plan view.

  The arm 31 c of the swinging rod member 31 is fixed to a side edge of the footboard 30. That is, the pair of left and right arms 31c, 31c is disposed in a C-shape approaching each other rearward.

Further, as shown in FIG. 5, the base member 3 has a metal band-shaped contact member 32 having left and right ends fixed to the base end 31a of each swinging rod member 31.

The lower connecting rod portion 24 of the support member 2 has a screw hole 24g having a rear opening shape. The contact member 32 of the base member 3 has a through hole 32g (communicating with the screw hole 24g) corresponding to the screw hole 24g of the lower connecting rod 24 in the deployed state.
Further, a set screw member 5 for fixing the contact member 32 to the lower connecting rod portion 24 is provided. The set screw member 5 is screwed into the screw hole 24g through the through hole 32g from behind the contact member 32, and holds the base member 3 in the deployed state. If the set screw member 5 is unscrewed, the base member 3 can swing.

As shown in FIGS. 6 and 7, the base member 3 is swung upward to be in a folded state attached to the support member 2.
In the folded state of the base member 3, the footboard 30 is arranged in a leaning manner on the pair of pillars 20, 20 and swings from the horizontal installation surface G with a swing angle θ of 90 ° or more and less than 110 °. It is preferable to adopt a rearwardly inclined posture (which is referred to as a substantially vertical plane shape) when folded compactly.

  In the folded state of the base member 3, the support member 2 can be self-supported by the rod-shaped front projection 20d and the rod-shaped rear projection 20e at the lower end of the support 20. Installation and storage can be easily performed, and swinging of the base member 3 is also facilitated.

By fixing to the base member 23, the base member 3 is held in a folded state.

  In other words, the upper connecting rod portion 23 and the lower connecting rod portion 24 are used in combination with a portion for reinforcing the pair of columns 20, 20 and a portion for fixing the base member 3, thereby reducing the number of parts. The weight is reduced.

The base member 3 is held by the setscrew member 5 in the folded state, and the column 20 is held (locked) in the shortened state by the operating member 26, so that the storage state (posture) is achieved. Compared to the state of use, the front-rear dimension and the up-and-down dimension are small and compact.
As shown in FIGS. 7 (A) and 7 (C), in the folded state, the base member 3 does not protrude forward than the front end (tip) of the front protruding portion 20d, and is behind the rear protruding portion 20e. It is arranged so as not to protrude backward from the end (tip).

Further, as shown in FIG. 2, in the use state of being most extended struts 20, lean members 1 a leaning load applied from the user and F _1, leaning member 1 O point loading point leaning undergo F ₁ And Further, the pressing load foot board unit 30 receives from the user and F _3, foot board 30 is a Q point presser loading point for receiving the F _3. E is the distance between the point O and the point Q in the front-rear horizontal direction. If an excessive F ₁ is applied, the support member 2 to the fulcrum in contact with the installation surface G when going to fall backward and P point. Further, the height of the lean from the point P to the point O is H, and the distance before and after the load support from the point P to the point Q is S.

H (lean height) is set in advance based on a request from a user, a market survey, or the like. In addition, F ₃ is the weight of the user. Then, in a maximum tension state of the most unstable prone struts 20, if F ₁ is applied to the leaning member 1, since the support member 2 does not fall rearward _{(F 1 × H) <(} F ₃ × S) must be satisfied. That is, even if a large leaning load (F ₁ ) is applied to the leaning member 1, if the value of S is large, the support portion 20 is safe without falling backward. Therefore, by providing the rear protruding portion 20e, it is possible to increase the value of S without extending the base member 3 forward. That is, the size of the base member 3 is reduced while enabling the user to lean on the safety.

  Further, there are no running rolling elements such as wheels near the rear end of the rear protruding portion 20e, so that even if it is slightly inclined, it can be used safely without slipping (not running).

  As shown in FIG. 1, the footrest portion 25 of the support member 2 is configured such that one end of the U-shaped rod member is fixed to one of the pillar portions 20 (the outer cylindrical portion 22) so as to protrude forward, and a U-shaped The other end of the rod member is fixed to the other pillar portion 20 (outer cylindrical portion 22) in a forwardly protruding manner, and the middle portion of the U-shaped rod member is made horizontal left and right. Such a configuration can contribute to a reduction in the overall weight and facilitate manufacturing. In addition, the user is easy to put on the foot and is easy to use.

In the other embodiments, although not shown, the support member 20 is formed as a single unit, and the base member 3 is pivotally attached to the lower portion of the single support unit 20 in a swingable manner. Then, the lower end of one support 20 is formed in an inverted T-shape in side view having a front protrusion 20d and a rear protrusion 20e which are horizontally front and rear, so that the base member 3 can be self-supported in a folded state. It is composed. More specifically, a metal plate material is fixed to the lower end of the outer cylindrical portion 22 in a horizontal plane to form a plate-shaped front projecting portion 20d and a plate-shaped rear projecting portion 20e. The lateral width of the plate-like forward protruded portion 20d, preferably in the lateral width dimension W ₂ of the lower end of the support member 2. Further, a screw hole 24g for holding the base member 3 in an expanded state is provided at a lower portion of the support portion 20, and a screw hole 23g for holding the base member 3 in a folded state at the upper and lower middle portions of the support portion 20. Is provided. Further, a left and right horizontal rod member is fixed to a lower portion of the support portion 20 to form a footrest portion 25. As described above, by making the support member 2 have a single-column structure, the weight can be further reduced, the number of parts can be reduced, and the manufacture becomes easy. Other configurations, functions and effects are the same as those of the above-described embodiment.

  The design of the present invention can be changed, and the shape of the leaning member 1 is free. The leaning member 1 may be provided on the column 20 so as to be movable in the front-rear direction, but is preferably fixed (fixed) to the column 20 for weight reduction and simplification. In FIG. 5, the contact member 32 may be in contact with one of the rear surface 20k of the column 20 and the rear surface 24k of the lower connecting rod 24.
