Description

Application of Article 30, Paragraph 2 of the Patent Act The patent applicant, Tsutomu Hayashida, made public by selling his invention, an assembly-type loft bed (product name, Enie), through an online shopping site on March 4, 2018. did

The present invention relates to a knockdown loft bed.

There has been an increase in Internet sales of foldable beds.
In other words, because the bed itself (a bed that is not assembled; hereinafter referred to as a "finished product bed") is a relatively large product, it is difficult to sell a finished product bed as a product in retail stores. In addition to exhibiting and securing inventory, a large space is required. For this reason, the types of finished beds that can be sold must be limited to some extent according to the available space, and the fixed costs for sales tend to be large due to the securing of space.
On the other hand, in online sales, such product displays can be done online using photographs, etc., and it is easy to flexibly change the inventory according to the sales volume. In particular, as for the assembled bed, compared with the finished product bed itself, it is possible to reduce the storage capacity as a product, and it is possible to secure more inventory in a smaller space.
For this reason, the knockdown bed has a high affinity with online sales and can be said to be a product that is very suitable for online sales.

In addition, the foldable bed can be said to be a product suitable for the current lifestyle.
In other words, there are various needs such as family structure and living environment, and there are various needs from highly versatile to niche. Cheap. In addition, the knockdown bed is more difficult to transport than a complete bed, compared to a detached house such as an apartment, and is easy to handle even when there is limited space for delivery.
For this reason, the foldable bed can be said to be a product suitable for the current lifestyle.

On the other hand, issues such as safety and durability tend to be a problem with knockdown beds.
That is, since a knockdown bed is completed by assembling a plurality of members, the members themselves tend to be smaller than a finished product bed. In addition, since the knockdown bed is assumed to be assembled by general consumers, it cannot have a complicated structure compared to the finished product bed, and needs to have a simpler structure. From this point of view, assembled beds are generally inferior in terms of safety and durability compared to finished beds.
Among these assembled beds, the bunk bed called a loft bed has more safety and durability concerns than a single-tiered bed. Various technologies have been proposed (Patent Document 1).

Patent Literature 1 discloses a technique related to an assembly type loft bed, which is called a recombination type furniture. This technique provides a desk in the longitudinal direction of the first level (lower level) and a floor on the second level (upper level).
In this technique, a tabletop member that serves as a desk is provided on the far side in the widthwise direction so that it can be used as a desk.
However, in the ladder portion, the fixing points are the supporting column and the side frame portion of the upper step, and the balance as the fixing points is not preferable. In such a case, the ladder part is weak against the force from the inside or outside in the horizontal direction, and there is a problem that the fixed part of the ladder gradually loosens.

In addition, the current trend of assembled loft beds is of the type described in Non-Patent Document 1.
In other words, the loft bed and the ladder are designed to be easily separated from each other, and the ladder is hooked diagonally to the upper part of the loft bed.
In the case of such a structure, although there is not much concern about it coming off when climbing a ladder, there are problems in that it can easily come off due to the force from the inside in the horizontal direction, and the hooked part on the upper level becomes weak. was

a first reinforcing frame arranged and fixed in the longitudinal direction on the same side as the fence side frame;
a second reinforcing frame arranged and fixed in a lateral direction on a side orthogonal to the fence side frame;
at least
Said top plate member is arranged in the short direction of said lower part and fixed to three members, ie, said first reinforcing frame, said second reinforcing frame, and said lifting ladder. It's a loft bed.

In a second configuration of the present invention, the ascending/descending ladder comprises a pair of ladder supports and a plurality of ladder treads installed on the pair of ladder supports,
Furthermore, a top plate fixing member separate from the ladder treads is installed on the pair of ladder supports, and the top plate member is fixed to the lifting ladder via the top plate fixing member. It is an assembly type loft bed described in.

A third configuration of the present invention is the knockdown loft bed according to the first or second configuration, wherein the ascending/descending ladder is arranged at a longitudinal end of the knockdown loft bed.

Below, the case where the ladder 5 for raising/lowering is installed in the right side of loft bed 1' is mentioned as an example, and is demonstrated.
When installing the lifting ladder 5 on the right side of the loft bed 1', the installation side frame second component member 2C2 is assembled to the installation side frame first component member 2C1 as shown in FIG. 11 to fix. As shown in FIG. 1, when the elevating ladder 5 is installed on the left side of the loft bed 1, the installation side frame second component member 2C2 is turned upside down and assembled to the installation side frame first component member 2C1. All you have to do is

Next, as shown in FIG. 3, the headboard 9 and the footboard 10 are fixed to the front and rear ends of the fence side frame 2B and installation side frame 2C using round nuts 12 and screws 13 and 14, respectively. As a result, the upper stage portion 1A is supported by the supports 4 erected at the four corners.

Next, as shown in FIG. 4, a pair of upper and lower first reinforcing frames 7A, 7B are installed and fixed between the left support columns 4, 4 of the headboard 9 and footboard 10 using round nuts 15 and screws 16, respectively. This improves the longitudinal stability of the loft bed 1'.

Next, as shown in FIG. 5, twin beam protectors 17A and 17B are fixed using screws 30 to the lower parts of the opposite surfaces of the fence side frame 2B and the installation side frame 2C, respectively, and the twin beam protectors Both ends of 17A and 17B are fixed to a pair of front and rear struts 4 and 4 using round nuts 18 and screws 19, respectively.

Next, as shown in FIG. 6, (1) two hooks 21 are fixed to the hook decoration 20 using thin wooden dowels 22 and screws 23, and (2) the hook decoration 20 is attached to the headboard 9 and the footboard. 10 is fixed to the upper end of the lower stage portion 1B using a screw 24. As shown in FIG.

Next, as shown in FIG. 7, a climbing ladder 5 is installed vertically at the front end on the right side of the loft bed 1'. More specifically, the upper end of the lifting ladder 5 is fixed to the installation side frame 2C using screws 25 .

Next, as shown in FIG. 8, the top plate member 6 is fixed to the three members of the first reinforcing frame 7A, the second reinforcing frame 8A and the lifting ladder 5 using screws 26. As shown in FIG. In this case, the top plate member 6 is fixed to the lifting ladder 5 via the top plate fixing member 5C.

Next, as shown in FIG. 9, the anti-warp member 27 is installed and fixed using screws 28 between the twin beam protectors 17A and 17B.

Finally, as shown in FIG. 10, the first floor member 2A1 and the second floor member 2A2 are arranged on the twin beam protectors 17A and 17B.

As described above, the assembled loft bed 1' is obtained.

In the above embodiment, a top plate fixing member 5C separate from the ladder treads 5B is installed on the pair of ladder supports 5A, 5A, and the top plate is attached to the lifting ladder 5 via the top plate fixing member 5C. Although the case where the member 6 is fixed with screws has been described as an example, the present invention is not necessarily limited to such a configuration. For example, an auxiliary member that bridges the lifting ladder 5 and the top plate member 6 may be used. Alternatively, screw holes may be provided in the ladder post 5A and the ladder footboards 5B, and the top plate member 6 may be directly screwed and fixed to the ladder post 5A and the ladder footboards 5B.
