Description:
Device for jumping and water activities

Various types of garden trampolines and swimming pools are previously known. Some of these are referenced in a number of patent publications, including United States Patent 6447426, United States Patents 5385518, 4598904, 4393528, 5813946, as well as the United States Patent Application 2005/0043122.

The above publications describe everything from trampolines in the form of some kind of inflatable fleet for use in open water or in the sea to more specialized arrangements such as an inflatable pool or a so-called "jumping castle" which can be filled with water, among other things.

Among the commonly known typical trampoline arrangements are the circular trampolines, which are widely used in gardens all over the world. Also well-known are various types of garden pools, both inflatable and other types. The subject of the present invention, which is not previously known, is a device of a type comprising both a pool and a trampoline in a single device.

Some people have both the space and financial resources necessary to have both an ordinary garden trampoline and a swimming pool in the garden. However, a common constraint among the current users of both existing trampolines and swimming pools is probably the lack of space or economics to acquire both a trampoline and a swimming pool.

The present invention aims to overcome this and other limitations of existing trampolines and swimming pools by providing a type of garden pool trampoline which is combinable and is neither more expensive nor more space-consuming than such trampolines and pools.

The objects of the present invention are achieved by a device for jumping and water activities, being of either a permanent or transportable and/or inflatable type, characterized in that the pool and trampoline constitute two juxtaposed and integrated parts of the same device, with the trampoline 1 and pool 4 sections being separated by a suitable division at the center of the device in the form of a crossbar, and this division also being a means for attaching the trampoline section. Preferred embodiments of the device are set forth with more particularity in claims 2 through 9.

The present invention will be explained in more detail with reference to the accompanying drawings, in which:

Fig. 1 is a sectional view of the device for jumping and water activities,

Fig. 2 is a top view of the device,

Fig. 3 is a sectional view of an alternative embodiment of the device, Fig. 4 is a top oblique view of the device, in another embodiment for a permanent swimming pool,

Fig. 5 is a top oblique view of the device, in another embodiment for a permanent swimming pool,

Fig. 6 is a side view showing a particularly preferred embodiment of the device, and

Figs. 7a, b, c, d are side views of a further embodiment of the device.

In a particularly preferred embodiment of the invention, an inflatable (using a pressure pump, for example) device is contemplated wherein a one part of the device includes a trampoline section 1 of a suitable typical trampoline mat rubberlike fabric, which is attached to the inside of the pool edge by way of attachment means 2, such as springs, rope, mounting loops, or the like. Optionally, trampoline section 1 may also be provided with a silicone coating or another "antiskid" coating as it, as a possible consequence of the novel features of the device, may become wet during use.

The other part of the device is separated from the trampoline section by some kind of partition wall or a suitable division 3, so that pool section 4 and trampoline section 1 are adjacent to each other but still separated, so as to prevent anyone from being able to swim under the trampoline, for example. This is fully prevented through the use of such a partition wall or suitable division 3. Another intended and important function of said partition wall 3 is to allow an optional level difference between the trampoline and pool sections. To enable the invention to be imple- merited as a safe and secure structure, the water depth of the pool and/or the height difference between the pool and trampoline must be sufficient, so that a user will not hit the pool bottom when jumping from the trampoline section to the pool section. This latter feature is not a necessity but rather a contingency in consequence of what is provided by the invention.

Constructing the device in such a manner that there is a height/level difference from the trampoline to the water surface of the pool reduces the risk of accidents and also creates a new and exciting dynamics with respect to the jumping and water activity. Said partition wall may be designed so that it is necessary to "jump over" the partition wall to get into the pool, and also so that it prevents water from migrating or leaking from the pool section into the trampoline section.

As such, this division constitutes an important part of such a preferred implementation of the device of the invention, and may generally be of an inflatable type. Additionally, the device can be constructed in such a manner that the height above the ground of the trampoline section is adjustable according to which holes are used for attachment means 2. For instance, notches or holes can be provided in the outer walls of the device, around the trampoline section, with a spacing of 10- 20 cm, for example, so that the trampoline section can be used at different heights. A semi-circular trampoline section 1 is then obtained which can be pushed into one of the "notches" from outside the device.

However, in the simplest embodiment of the device, the trampoline section is integrated at a given height and appears when the device is inflated.

As an exemplary height difference between the two sections, trampoline section 1 could be situated 50-100 cm above the ground, and division 3 could be situated at approx. 120-130 cm, or perhaps even higher (se Fig. 1 ). This will force the user to jump at a lower level (e.g. 50-60-70 cm) than the water level of pool section 4 (e.g. 1 10-120 cm). Additionally, this will make sure that the user does not achieve too much height when jumping, relative to the water surface and depth of the pool.

In the particularly preferred embodiment of the device, as seen from above

(Fig. 2), it could have the form of a circle divided at the centre, consisting, for ex- ample but not necessarily, of two semi-circular parts (being shaped as either a "Φ" or mirrored "D's").

Fig. 3 shows another exemplary embodiment of the device, in which a lower division 3, below water level, or alternatively no division at all, is used, so that the water also fills the trampoline section, but only to such an extent that the user jumps on a trampoline section suspended in water, forming a type of "underwater trampoline", and in which one may let oneself fall or jump into the pool section. The water depth in this trampoline section will be sufficiently shallow to render jumping possible, with a depth of 20-50 cm, for example, being preferred.

Other embodiments of the invention can be either a type of "tent equipment" like package which is specially adapted for different types of swimming pools (either inflatable or other types), or garden trampolines.

For the former case, the package can be conceived as being based on a circular garden pool, in this case fitted with attachment means 2 around the edge and with a suitable division 3 in the form of a padded crossbar having attachment points across the centre of the pool, in which springs or mountain-climbing loops are attached and in which the trampoline is then mounted to extend an angle of 180 degrees around half the swimming pool.

The next step is then to install a suitable trampoline mat (suitability refers to springiness of the material relative to the water/pool depth as well as other physic- cally desirable features such as water robustness, antiskid coating, and so on) in such a manner that a 180 degrees trampoline is obtained, leaving the remaining 180 degrees available for swimming. Also included in this case is a stronger division in the form of a soft or padded crossbar as well as an underwater net extending from division 3 to the bottom of the pool, which both ensures the stability of the device and also prevents a user from swimming under trampoline section 1 while one or more other users are using the trampoline section for jumping.

In a further example, one may use existing garden trampolines as a base for using the invention, and then carry out the invention in adaptation thereto. Then, for example, one would keep the iron frame around the garden trampoline (typically cir- cular) but, according to the invention, add a crossbar across the centre thereof to divide the frame into two sections (as in Fig. 2), after which an e.g. semi-circular trampoline mat is strapped from the crossbar to the pre-existing attachment means 2.

As an alternative, an existing trampoline mat could be used by stretching the mat around the crossbar, which is located in the position of division 3 as illustrated in Fig. 2, and back so that it is "folded double" and has a semi-circular shape instead of a circular shape. Then a pool section (inflatable or made of a hard plastic or another material typically suited for a garden pool) having a semi-circular shape, for example, is installed into the remaining part of the trampoline frame. As in other implementations, also in this case a partition wall or suitable division 3 and height difference is ensured, so that the pool has a depth that is greater than the trampoline height. Division 3 may then simply comprise the pool edge, possibly including a soft pad extending down to the crossbar to protect a falling jumper, etc.

In this latter implementation of the invention any existing trampoline can be converted into the device for jumping and water activities by way of a few but innovative steps as described.

An antiskid fabric or impregnation may be applied to the trampoline mat, so as to make it easier to use should it become wet. As a further feature of novelty, and also as a security measure, it is possible to provide rubber swimming shoes or the like which may be used for increased safety and at the same time provide a perhaps even more general and new overall concept in using the device, especially in the embodiment of Fig. 3.

An additional feature is that the bottom of pool section 5 of Figs. 1 and 3 can be padded to protect from impact against the bottom, etc., either by way of foamed rubber pads, air from the inflation process, or the like. This constitutes a further way of providing a device which differs significantly from the prior art and at the same time is safe in use.

As a result of these and several variants of the invention, a new type of device for jumping and water activities is obtained which combines two of the most widely used and popular outdoor toys, namely pools and trampolines, in a single device in a secure and safe manner as compared to what is known from the prior art. Regardless of how the invention is carried out, it will also be possible to install a safety net around the trampoline section, as in conventional garden trampolines.

Moreover, in various implementations of the invention, different shapes for the device as well as other design variations are conceivable that don't differ significantly in the technical solution. Hence, the device may also be implemented as a set of parts, so that the invention can be used with existing garden pools or permanent (built-in) swimming pools. This would also benefit those that already have a garden pool of some type and that have neither the space nor the financial resources needed to acquire a separate trampoline.

It is also contemplated that the invention can be further secured for its safe use by selectively preventing the users from jumping into the pool section by covering this section in an appropriate manner, e.g. using a padded pool cover. In the present invention it is considered to be a feature of novelty in itself that the trampoline and pool components are embodied in a single device for outdoor use.

It is further contemplated that the division 3 (which may be formed by an inflatable pool edge) can also be configured in such a manner that it provides a small slide into the pool section. This is in itself a marginal design change which may provide for additional functionality.

As a result of the adaptations for garden pools and the like, the above mentioned limitations are overcome for users of both conventional trampolines and conventional garden pools and the like and a device is provided that combines a trampoline and a pool in a safe and feasible manner, for users which are prevented from acquiring both. As such, an invention bringing about greater versatility and joy especially for families with children is provided, of which a possible additional benefit is even more outdoor play as compared with more technologically sophisticated indoor toys. Figs. 4 and 5 show an embodiment in which division 3 includes a support structure 6 extending downwardly into the pool section, e.g. in the form of a telescopic (height adjustable) support leg provided with suction cups, for example, for added grip, and which is attachable to a custom-made underwater net 9 as mentioned above for preventing a user from swimming under the trampoline section. The net may also be secured at the bottom of the pool section in an appropriate manner e.g. by way of weights, small suction cups 10, or the like. The height of trampoline section 1 can be adjusted by means of, for example, a number of height adjustable support legs 6 or other means suited for the purpose, which ensures a safe and sound use in the vicinity of the edge of the pool section as well as an appropriate height relative to the water surface in pool section 4. Also in this type of embodiment it will be possible to use some kind of safety net 8 or the like for added security so that it will not be possible to unintentionally fall off the trampoline section onto a hard surface.

Trampoline section 1 , as a further advantage of its adjustable height, can also be conceived to slope downwardly towards the pool section to make it easier to jump into the water, and such a slope, perhaps in the range of ten to twenty degrees, will reduce the chance that a user jumps in the opposite direction if not a safety net 8 or the like is used.

These and other embodiments of the invention are intended to benefit those who already have some kind of permanent garden pool, but who have neither the space, desire, nor economy to also acquire a separate trampoline.

Fig. 6 simply is a three dimensional illustration of the embodiment described above and referred to in Figs. 1 , 2, and 3, showing how a typical safety net 8 may be added and also how a fully inflated (by a pressure pump or the like) device for jumping and water activities 1 1 may appear.

Fig. 7 shows an example of said package variant or conversion kit enabling the conversion of an ordinary traditional trampoline to a device for jumping and water activities as described, with Figs. 7a, 7b, 7c and 7d each showing steps for carrying out this conversion. In Fig. 7a, an ordinary garden trampoline is shown, and in Fig. 7b the trampoline mat has been removed. Fig. 7c shows how to add a cross- bar 3 and mount a specially adapted trampoline section 1 using attachment means 2. Fig. 7d then shows, in a last step, how to fit the protection over the crossbar 3 and pool section 4 at a height difference above the trampoline section and having bottom floor protection 5, with the possibility for a safety net 8 surroun- ding the arrangement.
