Description

[Detailed description of the invention] This invention relates to a hanging health device that also serves as a stepladder.

Traditionally, the hanging health device and the stepladder were independent, and both had a considerable height, and the hanging health device required quite large legs, so it was economical to have both of them. There were problems in that it was a heavy burden and required a large space for storage when not in use.

This idea solves the above-mentioned problem by making the stepladder double as the legs of the health device.
It is possible to obtain these at a lower cost than purchasing them separately, and the storage space when not in use is small, and the hanging frame of the hanging health device can be used as a handrail or safety fence when used as a stepladder. It is an object of the present invention to improve safety by making the hanging frame easier to adjust, and to make it possible to easily adjust the height position of the hanging frame with a simple structure.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, 1 and 2 are the front and rear stepladder bodies,
These have left and right vertical rods 3, respectively. Connecting plates 5 are fixed to the upper ends of the left and right vertical bars 3 of one stepladder body 1, respectively, and the upper ends of the left and right vertical bars 3 of the other stepladder body 2 are pivotally connected to these connecting plates 5. The front and rear stepladder bodies 1 and 2 are connected so as to be openable and closable. An inverted dish-shaped upper tread plate 4 is fixed to the upper bent portion of the connecting plate 5, and this upper tread plate 4 allows the front
The upper ends of the vertical rods 3 of the rear stepladder bodies 1 and 2 are covered. The vertical rods 3 on both sides of the front and rear stepladder bodies 1, 2 are connected to angle-shaped tension rods 6b, 6c which are bendably connected at the pivot axis 6a of the body, and the end of the connecting plate 5 is bent. This prevents the front and rear stepladder bodies 1 and 2 from opening beyond a predetermined angle. On one of the front and rear stepladder bodies 1, 2, a plurality of upper and lower treads 7 are fixed at required intervals between the left and right vertical bars 3, and the front and rear stepladder bodies 1,
On the other side of the left and right vertical bars 3, a reinforcing bar/pedestal health bar 8 with at least a rounded upper part is installed at the lower end of the left and right vertical bars 3, and one is also installed at the top of the left and right vertical bars 3. A footboard 7 is fixed.

The vertical rods 3 of the stepladder bodies 1 and 2 are made of aluminum pipes having a substantially rectangular cross section and have vertical grooves 3a formed on at least the outer surface thereof, and the upper and lower fixing plates 10 of the support member 9 are connected to one of the stepladder bodies 1, 2 vertical rod 3,
They are fixed by being fitted into vertical grooves 3a provided on their outer surfaces. A support pipe 11 is attached to the fixed plate 10.
Both ends of the vertical rod 3 are fixed, and a support member 9 made up of these is disposed on the top of the vertical rod 3. Both sides 12a of a hanging frame 12, which is a pipe bent into a substantially U-shape from the front, are slidably fitted into the support pipe 11, and the upper end 12b of the hanging frame 12 is approximately perpendicular to the other stepladder main body 2 side. The upper tread plate 4 is slightly bent to the outside and protrudes outward.

The fixing means 13 for the hanging frame 12 is constructed as follows. That is, the connecting rod 15 is inserted from the inner end of the left and right locking rods 14 which are slidably and rotatably passed through the connecting plate 5 and the upper end of the vertical rod 3 of one stepladder main body 1. The left and right side portions 15a are integrally bent downward and are provided with one round bar. Further, the lower end portion of the connecting plate 5 is bent inward in the left and right direction, and the left and right side portions 15 of the connecting rod 15 are
a forms a cam 16 to be engaged, and on both sides 12a of the hanging frame 12, locking portions 17 consisting of holes into which the locking rods 14 are elastically engaged are formed in multiple upper and lower stages at required intervals. . When the left and right side portions 15a of the connecting rod 15 are rotated to engage the cam 16, the connecting rod 15 is elastically deformed, and the locking rod 14 provided integrally with the connecting rod 15 is elastically deformed. Retracts and enters the closed state, and both ends 1 of the hanging frame 12
2a becomes slidable. In this state, set the hanging frame 12 to approximately the desired height, and then
When the right side 15a is removed from the cam 16, the locking rod 14
is energized in the direction of advancing and opening, so the locking rod 1
4 and the locking part 17 of the hanging frame 12, the locking rod 14 immediately advances and engages with the locking part 17, and if they do not match, the hanging frame 12 is moved. By slightly moving it downward or upward, the locking portion 17 and the locking rod 14 are brought into alignment and engaged. When the locking rod 14 is engaged with the locking portion 17, even if the user hangs from the hanging frame 12, the weight of the user is supported and the hanging frame 12 does not fall down unnecessarily.
Note that when the hanging frame 12 is at the lower end that is almost horizontal with the upper tread plate 4, the locking rod 1 is attached to the locking portion 17.
Even if 4 is not engaged, the bending of the upper end of the hanging frame 12 prevents it from lowering.

When the device configured as described above is not in use, the front stepladder main body 1, the rear stepladder main body 1,
2 is closed, and the hanging frame 12 is positioned at the lower end and along the vertical rod 3, thereby making it approximately the same size as a normal stepladder.

In addition, when in use, by opening the front and rear stepladder bodies 1 and 2 as shown by the solid lines in Fig. 1, it can be used almost in the same way as a conventional stepladder. let it rise,
If the hanging frame 12 is fixed by engaging the locking rod 14 with the locking part 17, the hanging frame 12 can function as a handrail or a safety fence when standing on the upper tread 4 or the upper tread 7. This allows work to be done safely. Furthermore, in order to use it as a hanging health device, by raising the hanging frame 12 to a height where the user can hang it and fixing it, the opened stepladder bodies 1 and 2 can be used as the legs of the hanging health device. It can be used like a health container. In this embodiment, with the front and rear stepladder bodies 1 and 2 open, the reinforcing rod and tread health bar 8 provided at the lower end of the other stepladder body 2 is stepped on with bare feet, so-called green bamboo stepping. Similar exercises can be performed.

In this invention, in order to prevent the connecting rod 15 from being located near the treadle plate 7 or being operated when it is not engaged with the cam 16 and getting in the way, the connecting rod 15 is connected to the upper footplate by a spring. 4 or may be held by an appropriate holder. Further, the support means for the hanging frame may have sliding bodies fixed to both sides thereof engaged with guide rails formed on the stepladder body so as to be slidable in the vertical direction. Furthermore, multiple steps of upper and lower steps are provided in the middle of both the front and rear stepladder bodies, and the upper stepboard is divided and fixed into the front and rear stepladder bodies, so that both stepladder bodies are extended in a straight line, similar to conventional stepladders. It may also be possible to use it as a ladder. Further, the locking portion may be provided with a recessed portion in the hanging frame instead of a hole.

As explained above, according to this invention, it can be used as both a dangling health device and a stepladder, and compared to the case where these are separate, the legs to stand up the dangling health device are not required, so it can be provided at a low cost. When not in use, the hanging frame can be lowered to the lower end, making it almost the same size as a regular stepladder, so the storage space is small, and when used as a stepladder, the hanging frame can be lowered to the desired height. By protruding it, it can be used as a handrail or a safety fence, making it possible to work at heights safely.Moreover, by engaging a part of the connecting rod with the cam, the left and right locking rods can be retracted at the same time. The locking rod is urged outward by disengaging the connecting rod and the cam, and when these align with the locking portion formed by the hole or recess of the hanging frame, the locking rod is engaged by elastic engagement. Since the hanging frame can be held at a desired height by engaging with the locking part, the left and right locking bars can be easily operated at the same time, and the locking rods can be held in the locking part by elastic engagement. The effect is that the height position of the hanging frame can be easily adjusted by engaging the hanging frame with a simple structure.
