JPS5937080Y2 - Composition of bed floor with variable elastic force - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a structure of a floor portion of a bed whose elasticity is variable.

Conventionally, as this type of device, there is a device in which a horizontal bar with elastic force is installed between side plates.

However, since the elastic force of the floor is uniform over the entire surface and is fixed, this does not take into account the size of the user's body or sleeping position when the pinerest is placed on it.

For example, some people may say that if your lower back slumps, you'll get tired of sleeping, so it's better to have a hard center part, and if you feel pressure on your back, it's difficult to sleep, so it's better to have a softer part of your back. Some people may say so.

Further, even if a floor structure that can meet such demands is created, the number of component parts increases, and technical problems remain, such as imprecise operation and difficulty in operation.

This invention solves the above-mentioned problems and allows the user to easily change the elastic force of the floor, that is, the hardness of the pinerest, to achieve a sleeping position that matches his or her own preference, providing a pleasant feeling of use. The purpose of this invention is to provide a structure for the floor of a bed that provides the following.

An embodiment of the present invention will be described based on the accompanying drawings.

The bed 1 consists of a base 2 and a floor placed on the base 2.

The base body 2 is separated from a headboard 4, a footboard 5, and a pair of side plates 6, and each end is connected to a bracket 7 by a bolt 8 (not shown).

Next, the structure of the floor section of the present invention will be described. Reference numeral 9 represents a crosspiece attached to the inside of the pair of side plates 6.

Reference numeral 10 denotes a flexible piece attached to the upper side of the crosspiece 9, and is formed such that 18 recesses 10a alternate with protrusions 10b.

Reference numeral 11 designates 18 U-shaped horizontal bars, all of the same size, which have sloped portions on both inner surfaces of their cross sections, and grooves 13 and curved protrusions 14 on both outer surfaces in order to have elasticity. .

Both ends of the horizontal bar 11 are fitted into the recesses 10a on the bar 9 to prevent outward deformation.

Reference numeral 15 indicates the inclined portion 1 when a load is applied to the horizontal bar 11.
In order to prevent the horizontal bar 11 from being more inclined, the horizontal bar 11
The fastener 15 is fitted into the groove 13 through curved protrusions 14 on the outer surfaces of both sides, and the fastener 15 is U-shaped with spherical protrusions 16 inside both ends.

Furthermore, by providing the fastener 15 with an elastic synthetic resin coating, it has the effect of preventing damage to the horizontal beam 11 and generation of abnormal noise.

The larger the number of fasteners 15 attached to the horizontal bar 11, or the narrower the interval, the harder the horizontal bar 11 becomes.

17 is a center wire with hooks 1 at both ends.
7a is firmly fixed to substantially central portions of the pair of parallel side plates 6 via the pillars 9.

Therefore, in addition to preventing the pair of side plates 6 from curving, the horizontal beam 11 is also prevented from separating from the recess 10a of the flexible piece 10 and falling.

In the above configuration, when assembling the center wire 17 to the base body 2, the center wire 17 is first attached to the pair of side plates 6 as described above.
Install it approximately in the center of the

Next, both ends of the horizontal beam 11 are engaged with the recesses 10a of the flexible piece 10 provided on the pillar 9, so that the horizontal beam 11 is placed thereon.

At this time, attention must be paid to the mounting position and number of the fasteners 15, and they must be mounted from the bottom surface of the horizontal bar 11 according to the part of the body that the user wants to stiffen and the degree of stiffness required.

Another possible method is to attach the stopper 15 so as to cover it from the upper surface of the horizontal beam 11, but in this case, both sides of the stopper 15 need to be long, and the load on the stopper 15 is reduced due to an increase in moment force. This is undesirable.

As described above, according to the present invention, the hardness of the horizontal rail can be changed simply by attaching and detaching the metal fittings, so the user can easily change the partial hardness of the floor part, and the pinerest can be placed on it. However, the cushioning properties and firmness can be made partially variable, and the partially variable cushioning properties and firmness can be adjusted to suit the user's body and sleeping position, making the bed comfortable for the user. It is possible to create a comfortable sleep for the user.

In addition, as an additional effect, compared to conventional horizontal bars that are made by cutting non-quality materials, the horizontal bars of the present invention can be manufactured by roll forming of steel plates or extrusion molding of synthetic resin, resulting in uniform quality. improvement of productivity, etc.
