Description

114149 A WATERPROOF DOOR AND METHOD FOR MANUFACTURING A DOUBLE BOAT, PARTICULARLY A LITTLE SHIP, SUCH AS A Kayak Deck.

The present invention relates to a packing hatch formed in the cover of a craft, particularly a small vessel such as a kayak, according to the preamble of claim 1.

10 Small craft, such as kayaks, commonly use packing hatches. The hatches are intended to facilitate the packing of equipment inside the ship. On the other hand, the ship generally has a bulkhead structure which, together with the hatch, forms the required float. For the above reasons, the hatch must be absolutely watertight. It is also advantageous in use that the door can be opened and closed as easily as possible.

According to the state of the art, the products of Figure 1 are known in which the hatch is formed by attaching, for example, a plastic frame (4) to the ship's cover (6). The hatch cover (5) is made of a flexible material, for example rubber. Install the lid:. by stretching the rubber over the frame. This way you get pretty good. water tightness. Weaknesses in the structure include expensive price, high weight of rubber when not floating, hatch can only be black, hatch is 25 centimeters obtuse, release agents used in rubber molding give a dirty surface, rubber and plastic force to use: * lubricants.

. ·. Figure 2 shows another known solution. In it, the hatch cover (5) 30 is made of a hard material. · A separate seal (7) is used under the hard cover. Fastening straps (8) or other similar constructions are used to fasten the lid and to provide the necessary sealing pressure. The drawbacks of this solution include, inter alia, that it is very difficult to achieve full water tightness, since the ship's thin hull lives in the waves, the hatch is usually even more expensive to manufacture than the rubber hatch and the hinging required makes the hatch difficult to use.

The present invention is based on a novel solution which utilizes in a completely new way the advantages of the prior art. According to the invention, it has now been possible to combine the advantages of the above solutions while eliminating their drawbacks. The solution according to the invention can now provide a completely waterproof solution, which can be advantageously manufactured by large-scale production methods, for example, by rye-rolling. Furthermore, the use of the product according to the invention is very easy.

The invention particularly relates to a packing hatch formed on the cover of a craft such as a kayak. It is essential to the invention that a waterproof packing hatch is formed on the cover of a water vehicle, which consists of a frame and a composite hatch cover which can be mounted on top of it. More particularly, the invention is characterized by what is stated in the claims.

. The invention will now be described in more detail by way of one example with reference to the accompanying drawings, in which: i * '25 Figure 3 shows section I -1 of figure 4.

Fig. 4 shows a lid of the packing hatch according to the invention and ...: top view of the frame 1 * Figures 3 and 4 show a preferred solution of the waterproof packing hatch according to the invention. The device according to the invention operates by using the known structure (4) used in the hatches as the hatch frame. The lid (5) is made of two or more thermoforms 3 114149, in the middle of which is used a hard plastic (1). In this case, the lid (5) does not sag and different colors can be used on the same lid. The plastic is lighter in weight than water, whereby the hatch cover (5) floats. At the edges of the door and under the hard plastic, elastic rubber-like muo-5 is used (2). This adheres to the hard plastic so that the hard quality and then the soft quality are injected into the injection molding machine. The plastics are then chemically bonded to each other. The attachment is also mechanically secured so that the soft quality is pressed into the holes in the hard plastic (3).

In addition to the above, the solution of the invention can also be implemented using only one type of plastic. That is, alternatively, the solution according to the invention is made of a single grade of plastic whose hardness can be adjusted in an injection molding machine. In this case, the plastic is molded into the edges soft and hard in the middle.

As shown in Figure 3, the water tightness is ensured by preventing the flow of water at the point (A) where the soft rubber contacts the frame (4). If water is released from the seal (A), the intermediate space of (B) prevents it from being raised capillally upwards. The second sealing is accomplished at (C), where a suitably selected clearance between the soft plastic and the frame allows for 100% water tightness. In other words, the watertightness of the packing hatch is ensured by preventing the flow of water by sealing at (A) both in the intermediate space (B) to prevent any capillary and in the final seal of (C).

According to the foregoing, it is essential for the invention that a waterproof packing hatch is formed on the cover (6) of the craft, which consists of a frame (4) and a composite packing hatch cover (5) mounted thereon. The composite hatch lid (5) is made of either two or more different grades of plastic and / or plastic, the hardness of which can be adjusted in an injection molding machine.

If the cover (5) is made of one type of plastic, the plastic is molded to the edges 10 soft and middle hard. On the other hand, if the lid is made of two or more thermoplastics chemically and / or mechanically bonded to one another, the top (1) of the lid is formed of a rigid thermoplastic and its bottom (2) and the hinged edges of a rubber-like elastic thermoplastic. The elastic thermoplastic is attached to the harder thermoplastic 15 by injection molding machine. In addition to the above, the bonding of the thermoplastics to each other is mechanically secured by pressing the elastic thermoplastic into the holes (3) of the hard thermoplastic.

The invention further relates to a method of manufacturing a hatch formed on the deck of a craft, especially a small vessel such as a kayak. It is essential in the method that a waterproof packing hatch is formed on the • I * of the craft, which consists of a frame and a composite packing hatch cover mounted substantially thereto. The process is characterized by what is stated above and more precisely defined in the claims.

,,,: It will be apparent to one skilled in the art that the invention is not limited to the above. but may be varied within the scope of the appended claims.
