Description

[Detailed explanation of the invention] This invention can be stored as one of the drawers in kitchen furniture such as sinks, cooking tables, washstands, or in the lower architrave or recessed part. This is about the springboard that was created. especially,
To make it easier for people of short stature and children to sit on top of the cabinet for cooking and washing the toilet, to make it easier to put in and take out items stored in the upper part of a hanging cupboard that cannot be reached, and to also make it possible to freely put in and take out the sink, etc. by using this step stool. This was an attempt to make better use of space and improve usability.

Various types of stepping stones have been proposed in the past, but
It wasn't actually on the market. This seems to be because most kitchen furniture such as sinks and countertops have architraves or inlets that can be pulled out as they are.

In other words, the height of the architrave is approximately 10 centimeters due to functional and design constraints, and even if you try to pull it out as is, you will not be able to obtain the necessary height as a step stool.

Another disadvantage of washstands is that the storage space under the washbasin is narrowed by the step, and the strength of the architrave is weakened.

Therefore, in this design, a foldable step stool using a parallel movement mechanism using a four-section rotation chain is integrated into the drawer, so that it can be stored neatly as one of the drawers. Even if it is stored in a ring or barge, the required step stool can be obtained without changing its height.

The following will explain the embodiments shown in the drawings.

1 is a step stool related to this invention, which is constructed integrally with a recessed plate 2 at the bottom of the sink.

A pressure welding rod 3 is attached to the back side of the recessed plate 2, and main frames 4, 4 are placed under the pressure welding rod 3 on both sides of the back side of the recessed plate 2.
are arranged in parallel, and at the rear of the main frames 4, 4, a support frame 5 connecting the main frames 4, 4 is connected by a support frame shaft 6, so that the entire frame is shaped like a frame. Note that 2a is a handle configured as a hole.

Four legs 7, 7, 7, 7 are rotatably supported on a rotating shaft 8 on the main frames 4, 4 and the inner recess plate 2 side. The one close to the recess plate 2 of legs 7, 7 is
When raised, it comes into pressure contact with the pressure contact rod 3 and stops vertically. Support frames 9, 9 are provided over the upper part of the leg 7 in the front-rear direction, and the support frames 9, 9 are also supported on the leg 7 by a rotating shaft 8. A top plate 10 is fixed onto the support frame 9 by means of adhesive, screws, or the like. leg 7
The upper end is formed in an arc shape so that it does not get in the way when the rotating shaft 8 is brought down. The lower ends of the legs 7 are designed to protrude downward from the main frames 4, 4 and stand on their own when raised. The pressure contact rod 3 serves as a front stopper for supporting the leg 7 on the side of the recess plate 2, and also serves to secure a space for the lower end of the leg 7 to escape when it is folded down.

A horizontal bar 11 is provided between the legs 7, 7 at approximately the center of the main frames 4, 4.

From the supporting frame 5, the legs 7, 7 are brought into contact with the horizontal beam 11. Leg support arms 12, 12 which are narrower than the inner diameter of the legs 7, 7 are provided in series, and the leg support arms 12, 1
A backing plate 13 is provided above the open end of 2. Therefore, the support frame 5, the leg support arm 12, and the backing plate 13 are formed into a frame shape, and function as a rear stopper by swinging around the support frame 5 as a fulcrum. The backing plate 13 prevents the horizontal beam 11 and the leg support arm 12 from coming off when raised.

A thin bottom plate 14 is provided on the supporting frame 5 side of the main frames 4, 4. The side of the recessed plate 2 is open because the legs 7 protrude. Since the bottom plate 14 and the recessed plate 2 touch the floor when they are slid, it is preferable that they are made entirely of resin, which is easy to slip, or that they are coated with resin.

When using the step stool 1 having such a structure as a part of the sink plate 2, the legs 7 stand upright when the entire table is pulled out and the top plate 10 is pulled up.
At the same time, the leg support arm 12 located under the top plate 10 is pulled up by the horizontal bar 11 and comes into contact with the horizontal bar 11 of the leg 7 to support it vertically. At this time, the backing plate 13 hangs on the horizontal beam 11 and supports the leg support arm 12 so that it does not fall down.

In order to store this step stool 1, first the leg support arm 12
Lift up the horizontal bar 11 and the leg support arm 12, and place the leg support arm 12 between the horizontal bar 11 and the top plate 10.
It is to push it deep inside. Then, the support frames 9, 9 overlap the main frames 4, 4, and can be slid into the architrave and stored.

In the explanations so far, a case has been shown that is integrated with the recess plate 2 of the sink, but of course, when constructed as an integral part of a general drawer, the recess plate 2 becomes the front plate of the drawer.

This idea consists of the above structure,
In other words, a folding step stool using a parallel movement mechanism using a four-section rotation chain is integrated into the drawer, and a stopper for when the step stands up is separately incorporated, so it can be stored in a folded state, allowing the step stool to be set to the desired height. You can either integrate it into the drawer that is usually attached to the sink, countertop, or vanity, or you can integrate it into the bottom drawer.
It can be stored in the architrave.

The step stool can be raised and lowered freely and can be pulled out, so it looks good and is easy to operate.It is always in a frequently used place, so it is not only easy to use, but also has a separate storage area for the step stool. There will be no need to do so.
