Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an improvement of an ironing board, and more specifically, to an improvement of an ironing board whose height is adjustable.

``Prior Art'' Conventionally, as this type of ironing board, the one shown in FIG. 2 is known.

This conventional ironing board has an upper side 2b' of a rectangular frame-shaped leg 2' on one side of the lower surface of the ironing board main body 1, and a vertical frame 2a' of the leg 2',
At the center of 2a', there is a vertical frame part 4 of the other side leg 4', which has a rectangular frame shape and intersects with the one side leg 2' in an X shape.
The central parts of a' and 4a' are pivotally connected by horizontal shafts 3' and 3', and on the other side of the lower surface of the ironing board main body 1, the other side legs 4' are arranged at multiple stages in the longitudinal direction of the ironing board main body 1.
Locking claws 20, 20, 20 that lock the upper side 4b' of the
... are fixed, and by selecting the locking position of this upper side 4b', both upper sides 2b' of both legs 2', 4',
By changing the distance between 4b', the ironing board body 1
The height from the floor can be adjusted.

Further, in the above conventional example, the locking claws 20, 20, 20
When the locks are released, both legs 2', 4' are pivotally connected to the ironing board main body 1 only at the upper side 2b' of the one side leg 2', so the upper side 4b' of the other side leg 4' Since the ironing board body 1 may be far away from the ironing board body 1 and folding and assembling may be complicated, a sliding rail is provided in the longitudinal direction of the lower surface of the ironing board body 1, on which the upper end of the other leg 4' is slidably guided. There are also suggestions.

``Problem to be Solved by the Invention'' However, in the former example of the conventional ironing board shown in FIG. 2, the locking position of the upper side 4b' of the other leg 4' is changed. It has the disadvantage that it is very complicated to do. That is, when changing this locking position, if the upper side 4b' of the other side leg 4' and the locking pawl 20 at an appropriate location are unlatched, both legs 2', 4' will be moved to the one side leg 4'. The upper side 2b' of 2' and the horizontal shafts 3', 3' become rotatable as axes of rotation, and the other side leg 4'
Since the upper side 4b' can change its position freely, in order to lock the upper side 4b to another locking pawl 20, both the rotation angles of the legs 2' and 4' must be adjusted. It becomes indispensable. Therefore, in order to perform this adjustment, it is necessary to overturn the entire ironing board and then use both hands to hold one leg 2' in one hand and the other leg 4' in the other hand. Ta.

In addition, the latter type of sliding rail not only requires an increase in the number of parts, but also requires a long distance to fold both legs into a flat shape that is approximately parallel to the ironing board body. However, it had the disadvantage that it resulted in a considerable increase in overall weight.

[Purpose] The present invention was developed in view of the above-mentioned drawbacks, and an object of the present invention is to provide an ironing board that has a simple and lightweight structure and whose height can be easily adjusted.

``Means for Solving the Problems'' In line with the above-mentioned purpose, the structure of the present invention, whose gist is the scope of the above-mentioned utility model registration claims, is to solve the above-mentioned problems by connecting the horizontal shaft portion 2b at the upper end to the lower end. The upper end of the one side leg 2, which is formed into an I-shape by connecting horizontal foot parts 2c, is pivoted to one side of the lower surface of the ironing board main body 1 by pivoting the horizontal shaft part 2b, At the center of the body 2, the center part of the other leg 4, which has an I-shape with a horizontal shaft part 4b at the upper end and a horizontal foot part 4c at the lower end, is pivoted by the horizontal shaft 3. The base end of a horizontal arm 6 facing the upper end of the one leg 2 is rotatably connected to the upper horizontal shaft 4b of the other leg 4, and the lower surface of the free end of the horizontal arm 6 has a Locking recesses 5a, 5 at desired intervals
b, 5c... are arranged in parallel, and a guide frame 9 from which the horizontal arm 6 protrudes freely is fixed to the lower surface of the ironing board main body 1, and a tip locking claw is provided on the ironing board main body 1. A locking lever 10 is pivotally mounted, and the locking lever 10 is biased by a spring 11 in a direction in which the portion 10a is locked in the locking recesses 5a, 5b, 5c, . This was achieved by taking technical measures.

"Function" Therefore, the ironing board of the present invention has the locking lever 10.
Rotate the handle portion 10c in a direction such as pulling it up against the biasing force of the spring 11 to release the lock between the tip locking claw portion 10a and the locking recesses 5a, 5b, 5c, etc. The horizontal shaft portion 2b, which is the upper end of the horizontal arm 6 to the other leg 4, is guided by the guide frame 9 and can freely slide in the horizontal direction (direction to change the distance from the upper end of the one leg 2). Become.

Therefore, when the ironing board main body 1 is on top and the lower ends of the one leg 2 and the other leg 4 are in contact with the floor in the normal usage state (upside down as shown in the first figure), the locking When the ironing board main body 1 is pushed down while the locking claw 10a at the end of the lever 10 and the locking recesses 5a, 5b, 5c... If the distance between the upper ends of the foot 2 and the other foot 4 is increased, and conversely the ironing board main body 1 is lifted, the distance between the upper ends of the foot 2 on one side and the foot 4 on the other side will be narrowed by their own weight. ,
Changing the intersection angle between the one side leg 2 and the other side leg 4 according to the height of the ironing board main body 1 from the floor,
At the same time, the distance (height) between both upper ends and both lower ends of one side leg 2 and the other side leg 4 is changed. Therefore, the end locking claw portion 10a of the locking lever 10 and the locking recess 5
a, 5b, 5c... with the locks removed and removed, the ironing board main body 1 is raised and lowered, and the ironing board main body 1
After selecting the height of
b, 5c... to prevent the ironing board main body 1 from descending against the load on the ironing board main body 1, and to set the height of the ironing board main body 1 to a desired height. It is possible,
The horizontal arm 6 has both a locking function and a sliding guiding function.

``Example'' Next, an example of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the ironing board main body. This ironing board main body 1 has a mesh 1b such as a lath mesh stretched over the upper surface of a frame 1a having an appropriately shaped shape, and a cushion material such as a non-woven fabric, although not shown, placed on the mesh 1b.
Further, a cover fabric (not shown) is disposed on the cushion material, but this is not limited to the illustrated embodiment, and any conventionally known shape and material may be used. In addition, when carrying out the implementation, the cover fabric, which covers the upper surface of the ironing board main body 1 through the cushion material, has its peripheral cord passage part turned to the back side of the ironing board body 1, and the If the string is tightened and detachably arranged on the ironing board main body 1, the cover fabric can be replaced, which is more practical.

In addition, 2 is a one-side leg body 2 having an I-shape with a horizontal shaft part 2b at the upper end and a horizontal leg part 2c at the lower end.
The upper end of this one side leg 2 is pivotally mounted to one side of the lower surface of the ironing board main body 1 by supporting the horizontal shaft portion 2b.

That is, the one side leg body 2 has one vertical bar 2a.
A horizontal shaft portion 2b is provided at the upper end, and a horizontal foot portion 2c is provided at the lower end.
The horizontal shaft portion 2b of the bearings 7, 7 is fixed to the frame 1a.

The horizontal arm 6 has its base end connected to a tube 12 through which the horizontal shaft portion 4b is inserted, so that it can rotate about the horizontal shaft portion 4b as a central axis.
a, 5b, 5c... may be appropriately shaped and arranged in a desired number at appropriate intervals, but if they are formed into rectangular recesses on the sides with the horizontal shaft portion 4b side being an inclined surface as shown in the illustrated example, the ironing board main body 1 When lifting the device, the tip end locking claw portion 10a can be naturally unlatched without having to operate the handle portion 10c of the locking lever 10 in your hand.

Since the horizontal shaft portion 4b slides in contact with the lower surface of the frame 1a, the portion of the frame 1a in contact with the frame 1a is covered with mantles 4d, 4d.

Further, a guide frame 9 is fixed to the lower surface of the ironing board main body 1, through which the horizontal arm 6 protrudes freely. This guide frame 9 is movable only in the horizontal direction where the horizontal arm 6 approaches and separates from the upper end of the one leg 2, and is formed into a cylindrical shape with an appropriate width so that the horizontal arm 6 is inserted through it. Good.

Furthermore, the ironing board main body 1 is biased by a spring 11 in a direction in which the tip end locking claw portion 10a is locked in the locking recesses 5a, 5b, 5c, . A locking lever 10 that can be attached and detached is pivotally mounted. This locking lever 10 is held with an intermediate shaft portion 10b pivotally supported by a support stand 13 fixed to the back surface of the ironing board main body 1, and a vertically bent end locking claw portion 10a uses this intermediate shaft portion as a rotation axis. By rotating, the locking lever 10 is attached to and detached from the locking recesses 5a, 5b, 5c, .
When the handle portion 10c bent into a crank shape is manually rotated against the urging force of the spring 11, the tip locking claw portion 1
0a to the locking recesses 5a, 5b, 5c, . . . can be attached and detached. Note that this locking lever 10 has a locking recess 5a of a tip locking claw portion 10a,
5b, 5c..., instead of the illustrated embodiment, a conventionally known method such as a slide type in which the handle portion 10c is slid in the horizontal direction using an appropriate link mechanism or the like, or a push button type may be used. It goes without saying that you can use other materials.

[Effects of the Invention] Since the present invention is as described above, it is possible to provide an ironing board in which the height of the ironing board main body 1 can be adjusted only by operating the locking lever 10 and raising and lowering the ironing board main body 1.

Particularly, in the present invention, the upper end of one leg 2 is pivotally supported on the lower surface of the ironing board main body 1, the upper end of the other leg 4 is connected to the lower surface of the ironing board main body 1 via the horizontal arm 6, and Since the foot body 2 and the other side foot body 4 are interconnected by the horizontal axis 3,
Even when the distal end of the locking claw 10a of the locking lever 10 is disengaged from the locking recesses 5a, 5b, 5c, etc., the other leg 4 does not separate from the back surface of the ironing board main body 1, and the horizontal arm 6 remains inserted in the guide frame 9, the height can be adjusted without looking at the back of the ironing board main body 1, and the height can be adjusted while the ironing board main body 1 is in the position in which it is used. The height of the ironing board main body 1 can be easily set.

In addition, a noteworthy effect of the present invention is that the horizontal arm 6 serves both of the functions of locking the other leg and slidingly guiding it, so the number of parts can be omitted, the structure is simple, and it is lightweight and inexpensive to manufacture. be.
