Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water bed, and more particularly to a mattress for a water bed with suppressed waviness.

A water bed usually consists of a strong frame made of a suitable plastic or wood material, and an ice bag, i.e., a water-containing pine tress, which is injected with water via a water injection means and placed on the frame. There is. The frame is
Typically made of vinyl or other flexible tarpaulin, it surrounds and supports the ice bag being filled with water.

In conventional water beds, when the user sits on the pinerest, lies down, or moves, the bed undulates or sinks, and the circumference of the pinerest collapses, which is not only uncomfortable. That's why water beds don't have a good reputation. Previously, to solve this problem,
Various attempts have been made, with varying degrees of success.

For example, a bulkhead device, a tying device, a tying device and a bulkhead device, or a float having both, can be placed on either the lower side of the top or the upper side of the bottom of the ice bag constituting the mattress for water beds. , or take both @+
2. -r, quieting the movement of pine tress. but,
The use of such conventional motion restraint means has the disadvantage that it is necessary to provide an extra waterproof seam at locations where large stresses are applied, and that the waterproof seam can sometimes tear, resulting in water leakage.

Gelling agents may also be used to suppress undesirable vibrations. However, gelling involves not only operational problems such as mixing, heating, and removal, but also because the viscosity changes depending on the amount of mineral components contained in the water used. If removed from the water, a large amount of gelling agent would be required to thicken the pine tress, resulting in significant costs for the user.

It has also been considered to fill the ice bags with foam plastic inserts to control not only the wave motion but also the sinking effect. However, foamed plastic inserts are bulky, and if they are packed in ice bags, they are difficult to package, handle, and ship, even if they are compressed to a certain extent to reduce their bulk. Even so, the ability to return to the original size is extremely low. When water is poured onto a mat containing a foam plastic insert, the insert contains air because it is a foam plastic insert, and this air cannot be evacuated from the pine tress. In addition, expanded foam plastic inserts not only impede heat transfer in the water, but they also act as sponges, making them difficult to drain when replenishing or replacing the water.

SUMMARY OF THE INVENTION It is therefore a principal object of the present invention to provide a pine tress for waterbeds having at least one water injection means which suppresses and controls undesirable wave motions and eliminates the tendency for significant sinking effects in the pine tress, especially at the periphery of the pine tress. be.

As discussed below, this objective may be achieved by diverging the energy of the wave front.

□ Also, to provide a mattress for waterbeds that is simple in construction, can control wave motion and sinking effects without the use of gelling agents or cumbersome foamed plastic inserts, and has supports at the periphery. This is also another object of the present invention.

Safety and advantages are of particular importance in the present invention. Conventional water beds designed to suppress undesirable wave motions include bulkhead devices, coil tie-down devices, foam plastic inserts, gelling agents, or similar materials to inhibit wave motion. Typically, a system is provided. The coil tie device and the structure having the bulkhead device are butt connected to, but are not limited to, the surface of the external ice bag. Therefore, the force of the waves acts on these bulkhead devices, separators,
Alternatively, when the tie hits the device, such restraint means simultaneously confront the wave front and pull the surfaces connected by the butt seams so that these seam points are susceptible to leakage. These restraints typically must restrain more than 1,000 pounds of water from being shifted. The associated stress typically causes tears to form at the butt seam and - If a tear occurs, it becomes impossible to repair the seam.The present invention solves these problems related to water leakage and seam rupture, and for this purpose,
A fibrous material is provided in the waterbed pine tress.

Unlike bulkhead devices, separators, seeding devices, and similar suppression devices that resist wave fronts without yielding, the fibrous materials used in the present invention are reticulated. Alternatively, it forms a lattice-like structure and serves to both break down the wave front and disperse it.

Therefore, unnecessary tension will not be generated. Therefore, the problems caused by strong tension, that is, tensile force, which tend to cause water leakage at the batt seam in mattons for water beds provided with conventional restraining means, can be avoided in the present invention. .

Compared to foam plastic inserts, which are difficult to store and heat, and also have drainage problems, the use of fibrous media as in the present invention simplifies bed preparation. Not only can it be easily packaged, shipped, conditioned, heated, and stored, but the bed can also be easily and easily filled with water, drained, or aerated. .

Furthermore, changes in the peripheral support or reinforcement of the pine tress, the settling effect, and the support in the center can be controlled by appropriately determining the position and shape of the internal fiber filling, as well as the type or type of internal fiber filling. It can be controlled by appropriate selection of materials. For example, one idea is to use a larger amount of filler closer to the periphery of the water bed to strengthen the periphery and reduce the settling effect at the periphery.

The waterbed mattress of the present invention is mounted on and supported by a strong frame, and includes a fibrous material that is resistant to decomposition in water, that is, it does not decompose even when immersed in water. It consists of an inflatable ice bag. The ice bag is typically constructed from a suitable waterproof panel. In a typical construction, the ice bag consists of a top panel, a bottom panel that is separate from the top panel, and edge or side panels interconnecting the top and bottom panels. However, the present invention is not limited to such a configuration, and may include a configuration in which the top, bottom, and side panels are separate members and are not connected.
It can also be applied to an ice bag having an integrated structure. The ice bag is also provided with one or more water injection valve means.

The fibrous material contained in the aforementioned ice bag, which can expand when water is poured into it, is resistant to the decomposition effects of water! ) and must be a nonwoven or very loosely woven expanded fiber product, structurally bound or unbonded.

In use, water is poured into an ice bag provided with a net-like, thread-like, or fiber structure cut into small pieces, and
Adjust the amount of water injected according to the user's preference.

Thereafter, when the user sits, lies down, or moves on the water bed pine dress, the fibrous material or fibrous structure is able to break up and dissipate the wave front created within the ice bag. I can do it. This is because the fibrous material or fibrous structure forms a net-like or lattice-like barrier against the movement of water.

The purpose, advantages, features, etc. of the waterbed mattress capable of absorbing water pressure waves in this way will become clear from the following detailed description of the embodiments, with reference to the accompanying drawings.

According to the invention, the fibrous material or fibrous structure is dispersed in the water within the ice bag. The fibrous material used in the present invention is a nonwoven or a very roughly woven expanded fiber product, or a mixture of both, and may be fixed with a binder or not fixed. It is okay even if it is not. - By way of example, but not exclusively, polyester fiber products may be considered, in which case the polyester fibers may or may not be bonded to each other with an acrylic resin;
It may exhibit a non-woven structure or a very loosely woven structure. Expanded fiber products used in the present invention, whether bonded or not,
It is not limited to the polyester fibers and other artificial fibers mentioned above. Other suitable fibers, cloths, or synthetic resins can be used as long as they can resist the decomposition effects of water. Furthermore, the material, ie the expanded fiber product, must be highly compressible. That is, the expanded fiber product must be capable of being compressed to dimensions of at least about 1710 mm or less of its original dimensions, while being capable of recovering substantially its original dimensions when immersed in water. Therefore, soft coiled materials such as expanded foam materials and "rubberized horsehair"
The material known as ged horse-hair) is insufficient to achieve the objectives of the invention.

The materials used in the present invention must be fibrous, net-like, thread-like, or cut into small pieces, so that air can easily flow through the lattice structure of each material. These properties mean that when air is included in the pine tress, materials such as conventional foam plastic inserts can Pine tresses tend to float toward the surface of the water, and this is important to avoid this tendency. 0.5 to 1 cubic foot, such as bonded or unbonded polyester fibers and other expanded fibers.
Materials having a density of 0.2 bond are suitable for achieving the objectives of the present invention. Also suitable are glass fibers.

Fibers that are not bonded to each other, but only intertwined, such as the rolled cotton commonly used in pillows, are within the scope of the present invention, but do not constitute a preferred embodiment. However, when using such fibers,
The water injection and drainage means must be equipped with a screen or filter to prevent clogging caused by such fibers.

Moreover, when we tried using the aforementioned fibers that were simply intertwined, the wave reduction effect was smaller than that of fibers that were bonded together. Furthermore, since each fiber floats freely in the water, problems remain in draining water. Additionally, such unbonded fibers can be very difficult to use during manufacturing and packaging;
A large amount is required compared to the fibers being bonded. The unbonded fibers used in the present invention include recycled polyester fibers from a garnet machine (waste fiber regenerator) attached to a scrim, recycled polyester fibers, and
Some include coarse polyester fibers.

When the material described here, that is, an expanded fiber product, is used for the pine tress, it is possible to attenuate only the movement of water, that is, the wave motion, without attenuating the thermal conductivity in the water inside the pine tress. .

As an example, the length, width, depth and thickness are each 84°72.
．． Three expanded fiber products made of unbounded glass fibers bonded with a female binder were attached to a 9-inch water bed pine mattress.

The nonwoven glass fibers were resistant to the degrading effects of water. The dimensions of each expanded fiber product (length, width, depth and thickness) are 64° and 64.2 inches, respectively.
I tied three pieces together and put them in one pine tress.

As another example, the length, width, and depth are each 84°72.
．． A 9-inch waterbed mattress was equipped with an expanded fiber product consisting of bonded polyester fibers. Specifically, this expanded fiber product was made of nonwoven reticulated polyester fibers fixed with an acrylic binder. In this example, the length, width,
Three expanded fiber products with a depth of 64° and 64.3 inches were used. In yet another example, two identical expanded fiber products having lengths, widths, and depths of 60.60.3 inches were used. In each case, multiple expanded fiber products were connected together into a single pine tress.

As another example, a waterbed mattress having a length, width, and depth of 84.60.9 inches was used, particularly with reinforcement around the perimeter of the pinetress. The expanded fiber product used was a polyester fiber filler with a length, width, and depth of 60 and 60.3 inches, which were connected together and put into a single pine tress.

As another example, a waterbed mattress measuring 63.45°5T inches in length, width, and depth was filled with 4 pounds of nonwoven, unbonded polyester fiber fill.

As yet another example, the length, width, and depth are 63°40
．． A 6-inch waterbed pine tress was filled with three interconnected glass fiber fillers measuring 60.40.2 inches in length, width, and depth.

All of these fillings were effective in forming a mesh barrier in the water inside the ice bag to suppress and diffuse wave motion.

The water bed pinerest in the above example is as described without any modifications. but,
These other embodiments are also contemplated according to the invention. That is, the ice bag constituting the waterbed mattress could be provided with flotation means along its margin, which would provide the same benefits as described in my U.S. Pat. No. 3,864,768. A peripheral support can be constructed to support a person sitting 2 on the peripheral edge of the bed. In detail, it is also possible to provide a floating peripheral support by providing a tubular air float around the periphery of the water bed mattress and injecting air into the float. In this case, an air valve is provided for injecting and exhausting air from the water bed mattress to the air float located inside the mattress.

Now, in FIGS. 1 to 3, the fiber products provided in the waterbed mattress of the present invention are roughly distributed inside the mattress, but in the drawings, the fiber products are relatively uniformly distributed. It is illustrated as being distributed. During use, textiles, especially unbonded textiles, become concentrated in areas or form cavities. As described above and as is clear from the drawings, the present invention can use either unbonded fibers, bonded fibers, that is, fibers bonded or fixed with a binder, or both.

Further, as mentioned above, the textile products as shown in the drawings may have a density of about 0.5 to 0.2 bonds per cubic foot, but the present invention is applicable to textiles having a density range of about 0.5 to 0.2 bonds per cubic foot. should not be limited to. The weight of the body of the expanded fiber product mentioned above per unit volume is −)(
It should not be confused with the weight per unit volume of each fiber, binder, or scrim alone in its unexpanded state, ie, compressed to reduce bulk. Each fiber, binder, or scrim has a weight per unit volume that is different from the weight per unit volume of the body of the expanded fibrous material placed at a desired location in the water bed to suppress wave motion. It has a weight of . When using bonded fibers, a large amount of binder is used, so the density may be dense. The amount and composition of the binder may vary without departing from the scope of the invention. Furthermore, as mentioned above, the fibers exhibit an expanded shape, that is, in the textile product used for the present invention, although the fibers are separated from each other, they randomly come into contact with each other everywhere. It has all the prescribed shapes.

As can be seen with reference to FIGS. 1 to 3, the water bed consists of a frame and a mattress 15 consisting of an inflatable ice bag with the aforementioned textile 9. The frame consists of a floorboard 11 placed on a base 12, and this floorboard 1.
1 and a side wall 13 that forms a box-like body with an open top as a whole. The floor plate 11 of this frame may be made of wood or other frame material, and may be assembled together with the side wall 13 in a well-known or publicly known configuration.

This pine tress, that is, the water bag 15 is formed on the upper rectangular panel 1.
4, a bottom rectangular panel 16, and a side panel connecting both panels 14,16.

Side panels 17 and end panels 18 connect the peripheries of top panel 14 and bottom panel 16 to each other, giving the pine tress as a whole an ice bag shape. These panels 17.1
8 is usually constructed by using the outer peripheries of the top panel and the bottom panel, and the edges of these outer peripheries are connected to each other by tight contact or by using an adhesive. In such a configuration, in the center of the panel 17.18, as shown in FIGS. will be formed along. Although the mattress of the present invention is not limited to having the shape or configuration described above, it is preferable to have the shape or configuration described above. The ice bag construction shown in FIGS. 1-3, ie, the single seam water bag 15, is suitable for practicing the present invention. Water bag 15
is provided with water injection means 20 in the upper panel for injecting water into the pine tress. As shown, a filter may be attached to this water injection means, if desired.

Water bladder or pine tress 2 in the embodiment shown in FIG.

9, and a water injection means, for example a plug 30, is connected to the top panel 26.
It is set in. However, the textiles used in this embodiment are bonded textiles that form the mesh barrier 31. The size and shape of this net-like barrier body 31 may be of any size without departing from the scope of the present invention. In FIG. 4, the bonded fabric is shown as being stationary on the bottom panel 27 inside the water bag 25, but in normal use, it is Move to.

It should be noted that this main body of the combined textile product 31 is not necessarily positioned as shown in FIG. 4, but may be positioned anywhere within the ice bag using any suitable means. Therefore, the present invention encompasses all the textile products 31 that are arranged within the water bladder 25 without being positioned in the specific state shown in FIG. Also,
