Description

Technical Field

[0001] The utility model relates to a carrying box and a pump for an inflatable water vehicle and a stand-up paddle board (SUP) with the carrying box. Background Art

[0002] A carrying box for a stand-up paddle board, also known as an SUP, is known from WO 2018 / 020308 A1. Utility Model Content

[0003] The purpose of the utility model is to improve the known carrying box.

[0004] Starting from a carrying box for an inflatable water vehicle, the carrying box has a container, which extends in a space spanned by a height direction, a longitudinal direction perpendicular to the height direction, and a transverse direction perpendicular to the height direction and the longitudinal direction and has a container accommodating space, which is limited by a top side, a bottom side opposite to the top side in the height direction and constructed as a container bottom, and a container wall connecting the top side to the container bottom, and the carrying box has a container external flange retained at the top side of the container for fastening the container to the SUP, the container external flange pointing outward when viewed from the container accommodating space, the proposed carrying box according to the utility model includes an inlet guided through the bottom for allowing air to enter the inner cavity of the SUP and at least one wall rib retained on the container wall, which wall rib is arranged to maintain a wall distance between a pump that can be accommodated in the container accommodating space and the container wall.

[0005] The proposed carrying box can be used for any inflatable water craft, such as a stand-up paddleboard called SUP, a kayak or other canoe, an inflatable boat, a sailboat.

[0006] The proposed carrying case is based on the consideration that conventional carrying cases for SUPs often have the disadvantage that the pump is either fixedly mounted and cannot be removed after the SUP is inflated, or the pump is loosely inserted and can fall out during use. If the pump remains permanently in the SUP, this results in unnecessary weight increase or, if the pump is not securely fixed, potential functional impairment.

[0007] The proposed carrying case is designed to safely and securely integrate the pump during SUP inflation, while also allowing for multifunctional use when the SUP is already inflated. The container's external flange provides a stable attachment to the SUP, while an inlet through the bottom allows direct air supply into the SUP's interior. Wall ribs ensure that the pump can draw sufficient air by maintaining the distance between the pump and the container wall.

[0008] In addition to these advantages, the carrying box offers the possibility of using it as storage space for personal items such as drinks, towels, or wallets after the SUP is inflated. The enclosed carrying box protects these items from water and ensures easier and more practical use of the SUP. A further advantage is that the carrying box, due to its structure, increases the structural integrity of the SUP and provides additional stability.

[0009] In a further development, the proposed carrying case includes bottom ribs designed to maintain a base distance between the pump and the container bottom. This further improves the pump's air intake, as the distance from the container bottom ensures that the pump does not rest directly on the bottom, thus enabling unimpeded air flow. This contributes to the pump's efficiency and performance and prevents any blockage or restriction of the air supply.

[0010] In another refinement, the bottom and wall ribs are constructed integrally. This significantly improves the mechanical structure of the load-bearing box due to the increased strength and stability of the integral rib structure. This results in better load distribution and reduces the likelihood of material weakening or cracking. Furthermore, since fewer separate components are required, manufacturing and assembly are simplified, reducing production costs and potential sources of error.

[0011] In an additional refinement, the carrying box includes at least one, and preferably several, additional wall ribs, wherein the wall ribs are arranged rotationally symmetrically with respect to one another about an axis of rotation extending in the height direction. This further improves the pump's air intake, as the pump is completely spaced from the wall. This ensures uniform air flow distribution and prevents clogging, thereby maximizing the pump's efficiency and power. Furthermore, the rotationally symmetrical arrangement contributes to the structural integrity of the carrying box, as it ensures uniform distribution of mechanical loads.

[0012] In a special improvement, the carrying box comprises a retaining wall extending around the inlet and extending into the container receiving space, the retaining wall having a fastening device preferably in the form of an internal thread, which serves to retain a valve into which the mouth of the pump can be inserted. In this way, the valve can retain air in the SUP while the pump remains removable. The advantage of the retaining wall is that it prevents water entering the container receiving space from entering the SUP. This effectively protects the inner cavity of the SUP from moisture. In addition, the valve is replaceable, which significantly improves the maintainability of the system. This makes it possible to simply maintain and replace the valve when necessary without having to dismantle the entire pump or the carrying box.

[0013] In a preferred embodiment, the valve includes an outer valve flange on its top side, as viewed in the height direction, and the bottom rib has a recess extending toward the bottom in the region of the receiving opening for accommodating the valve flange. This recess provides a stop against which the valve can be positioned, allowing the pump and the support box to be oriented relative to each other so that the nozzle can be precisely inserted into the valve. This ensures a precise and reliable connection between the pump and the valve, which increases the efficiency of the air extraction and minimizes the risk of leakage.

[0014] In another refinement, the container has an inner flange on the inlet extending inward from the retaining wall to limit the movement of the valve body. This restricts the path of the valve body, which improves the functional reliability of the valve. An additional advantage is that the inner flange prevents the valve body from moving beyond its designated position, thereby preventing potential damage and malfunction. This contributes to the durability and reliability of the valve.

[0015] In another refinement, the carrying case includes a protrusion, typically designed as a threaded protrusion, that is slipped onto the top side of the container onto the flange and serves to receive and retain the lid that closes the container. The container can be closed using this protrusion. This design offers several advantages: First, the lid pushes the pump into the inner cavity, so that the nozzle is securely pressed against the valve, ensuring a reliable air supply. Second, the protrusion provides a watertight seal of the receiving space, protecting the pump and other electronic components from moisture and water damage, particularly in humid environments, such as when used on water.

[0016] According to another aspect of the present invention, a pump for inserting into the container accommodating space of a carrier box in the proposed carrier box includes a housing, which extends in a space spanned by a height direction, a longitudinal direction perpendicular to the height direction, and a transverse direction perpendicular to the height direction and the longitudinal direction and has a pump accommodating space, which is defined by a housing cover, a housing bottom opposite to the housing cover in the height direction, and a housing wall with multiple suction openings connecting the housing bottom to the housing cover, wherein a pump mechanism for outputting an air flow through an opening in the housing bottom, which is preferably implemented as a mouth, a pump-electric device for driving the pump mechanism, and an electric energy supply source for supplying electric energy to the pump-electric device are accommodated in the pump accommodating space, and an operating switch is maintained on the housing cover.

[0017] The pump is based on the principle of directing the air flow downward while being operable from above. This offers several advantages. Firstly, it allows for simple and comfortable operation of the pump, as the operating switch is easily accessible on the top side of the pump. Furthermore, the suction opening assembly in the housing wall provides an efficient air supply that maximizes the pump's performance. Furthermore, the downward-directed delivery of the air flow ensures a direct and loss-free supply of air to the SUP, which shortens inflation time and increases efficiency. Finally, the integration of the pump electronics and energy supply within the pump housing allows for a compact design that minimizes space requirements and simplifies the operation of the pump.

[0018] According to a further aspect of the invention, a stand-up paddle board referred to as SUP comprises an inflatable chamber enclosed by an outer skin, on which one of the proposed carrying boxes is retained, wherein the proposed pump is inserted into the container receiving space of the carrying box.

It is shown:

[0022] Figure 3 Show Figure 1 and Figure 2 A three-dimensional view of the carrying box. DETAILED DESCRIPTION

[0023] In the figures, identical technical elements are provided with identical reference numerals and are described only once. The figures are purely schematic and in particular do not reflect actual geometrical relationships.

[0024] refer to Figure 1 , which shows a stand-up paddle board called SUP 2 in a space bounded by a height direction 4 , a longitudinal direction 6 perpendicular to the height direction 4 , and a transverse direction 8 perpendicular to the height direction 4 and the longitudinal direction 6 .

[0025] The SUP 2 is a water sports equipment embodied as a floating flat platform 10 , which serves to carry a user in a standing position in a height direction 4 while the user moves forward with the aid of a paddle (not shown in further detail).

[0026] The platform 10 of the SUP 2 consists of a standing surface 12 viewed in the height direction 4 and a vertical support 12 arranged opposite the standing surface 12 viewed in the height direction 4 and Figure 1 The water-supporting surface, which cannot be further seen in the middle, is in contact with the water during use and ensures the floatability of the SUP 2. The surrounding lateral SUP sheaths 14 connect the standing surface 12 with the water-supporting surface and contribute to the shape and strength of the SUP 2.

[0027] The standing surface 12, the water bearing surface and the SUP cover 14 are part of an outer skin 16 which surrounds the Figure 1 The inflatable air chamber is not further visible. When the SUP is inflated, the air chamber gives the SUP 2 its shape and rigidity and is accessible via valve 18, through which air can be introduced and exhausted. The outer shell is made of a robust, membrane-like plastic material that provides lightness and durability.

[0028] The SUP 2 may also be equipped with additional elements, not shown, such as invisible fins on the water-bearing surface, to improve stability and directional stability in the water. The entire construction of the SUP 2 is designed to evenly distribute the weight of the user standing on the standing surface 12 and ensure a stable, safe paddling feel.

[0029] In this embodiment, valve 18 is arranged in container receiving space 20 of carrying box 22, into which pump 24 can be inserted. Container receiving space 20 is located in container 26, which has a container bottom 28 (viewed from the bottom side in height direction 4) and an open container top side 30 opposite container bottom 28 in height direction 4, which are connected to each other by a container wall 32. A plurality of wall ribs 34 oriented in height direction 4 are attached to container wall 32.

[0030] For inflating the SUP 2, the pump 24 has a mouth 36 on its bottom side, viewed in the height direction 4, which can be used to inflate the SUP 2. Figure 2 The pump 24 has a housing 38 which is formed by a plurality of holes 4 at the bottom. Figure 2 The housing bottom 40 , which is visible in the figure, is defined by a housing cover 42 which is situated opposite the housing bottom 40 in the height direction 4 and a housing wall 44 which connects the housing bottom 40 and the housing cover 42 to one another.

[0031] The housing wall 44 of the pump housing has a slot 46, Figure 1 For the sake of clarity, only two of the slots are provided with reference numerals. The slot 46 opens the housing 38 toward the housing interior (not shown in detail), in which the pump mechanism, the pump electronics that drives the pump mechanism, and the electrical energy supply that supplies the pump electronics with electrical energy are accommodated.

[0032] The pump electronics consist of various electronic components responsible for controlling and driving the pump mechanism. They include a control circuit that receives signals from a switch 48 located on the housing cover, and a motor controller that regulates power to the electric motor. The electric motor itself converts electrical energy into mechanical energy, which is required to move the pump mechanism. By controlling the motor's speed and operating status, the pump electronics ensure efficient and reliable pump operation.

[0033] The pump mechanism consists of the mechanical components directly responsible for generating the air flow. This typically includes a piston or diaphragm driven by the motion of a motor. The piston or diaphragm moves within a cylinder, drawing and pressurizing air through slit 46. This air is then introduced into the air chamber of the SUP 2 through the nozzle 36. The pump mechanism is designed to achieve high-pressure performance and maintain a continuous and uniform air flow.

[0034] The electrical energy supply for the pump electronics can consist of batteries or rechargeable batteries. This energy source is housed within the housing and provides the necessary electrical energy to operate the pump electronics and the electric motor. An efficient energy supply is crucial to ensure that the pump has sufficient operating time and can fulfill its purpose without interruption.

[0035] Switch 48 is used to turn the pump on and off. When operated, it activates the pump electronics, thereby starting the electric motor. The electric motor then drives the pump mechanism, which generates an air flow through the nozzle 36. Thus, the nozzle 36 is the starting point for the generated air flow to exit the pump and enter the air chamber of the SUP to inflate the SUP. This coordinated function of the pump electronics, pump mechanism, and electrical energy supply provides an efficient and user-friendly inflation system for the SUP.

[0036] Furthermore, a charging connection, which passes through the housing 38 and is not visible, can be arranged on the pump 24 in order to recharge the electrical energy supply after the SUP 2 has been inflated.

[0037] In addition to the switch 48 , a handle element 50 is also formed in the housing cover 42 , which will be discussed in more detail below.

[0038] Now refer to Figure 2 and Figure 3 , the carrying tank 22 and the pump 24 will be described in more detail with the aid of these figures.

[0039] The container 26 has bottom ribs 52 that are held on the container bottom 28 and point toward the container receiving space 20. Each bottom rib 52 is formed integrally with one of the wall ribs 34. The individual rib combinations 34, 52 are arranged rotationally symmetrically about a rotational symmetry axis 54 oriented in the height direction 4. This means that the arrangement of the rib combinations repeats regularly when rotated about the rotational symmetry axis 54, but does not necessarily have continuous rotational symmetry.

[0040] Rotational symmetry means that the object can be brought into a position indistinguishable from its initial position by a certain number of rotations (e.g., 90°, 120°). The rib assemblies 34, 52 are arranged so that they overlap within a certain angular step when rotated about the axis of rotational symmetry. This evens out the mechanical loads and improves the structural integrity of the container.

[0041] In contrast, rotational symmetry involves continuous symmetry around an axis. An object with rotational symmetry remains unchanged under any arbitrary rotation about the axis of rotation. A cylinder or a sphere are examples of objects with rotational symmetry, as they remain unchanged under any rotation about their axis.

[0042] The inlet 56 is guided through the container bottom 28 and is covered and not visible in this embodiment by the valve body 58 of the valve 18. The valve 18 itself is constructed similarly to a valve as described in DE 10 2015 105719 A1, so its structure will not be discussed in detail.

[0043] A retaining wall 60 rises around the inlet 56 and is supported against the container bottom 28 by a plurality of supporting ribs 62. An internal thread (not mentioned further) is formed on this wall, into which the external thread of the valve 18 (as known from DE 10 2015 105 719 A1) can be screwed.

[0044] Each bottom rib 52 has, on its side facing toward the inlet 56, a recess 64 at the upper corner, as seen in the height direction 4, which recess forms a support shoulder for a valve flange 66 of the valve 18. During use, the valve is thus screwed into the retaining wall 60 until the valve flange 66 rests on the recess 64, counter to the height direction 4.

[0045] Once the valve 18 is screwed in and the inlet 56 is sealed against air escape, the pump 24 is installed in the container receiving space 20. The wall ribs 34 guide the housing 38 of the housing wall 44, allowing the mouth 36 to be precisely inserted into the valve 18. The mouth 18 is designed as a male bayonet lock element, as required for the bayonet lock according to DE 10 2015 105 719 A1. Once the mouth 36 is axially inserted into the valve 18, the bayonet lock can be closed on the handle element 50 by rotating the pump 24. This not only securely holds the pump in the container receiving space 20, but also creates a reliable, airtight connection between the pump 24 and the valve 18.

[0046] In order to fasten the container 26 and thus the carrying box 22 on the SUP 2, the container 26 has a container flange 68 on its top side viewed in the height direction 4. This container flange is bonded to the outer skin 16 from the inside of the SUP 2 against the height direction 4, thereby forming a container flange 68 on the top side of the SUP 2. Figure 1 By gluing the container 26 to the outer skin 16 from the inside of the SUP 2, the mechanical stability of the connection is improved because the container flange 68 is pressed against the outer skin 16 in the inflated state of the SUP 2.

[0047] Furthermore, a container outer thread 74 extends from the container flange 68 in the height direction, onto which a cap 76 for closing the container receiving space 20 can be screwed.
