Description

Technical field:

[0001] The present invention relates to a retractable sleeping device for travelers. State of the art

[0002] The patent family for US10383451B2 describes a portable head support system consisting of a base plate and a headrest connected by an adjustable hinge. This device is integrated into carry-on luggage or backpacks and allows for individually adjustable tilt to enable travelers to sleep more comfortably with their head tilted forward. However, the angle of the neck when the head rests on the headrest is unfavorable and could lead to tension. Furthermore, the overall stability of the construction is inconsistent, which is problematic during sleep movements, could cause awakenings, and thus disrupt sleep.

[0003] WO2007071977A2 shows a seat support consisting of an inclined main support surface for the upper body and head, supported by two fold-out legs. One pair of legs rests on the seat, the other on the floor. The support allows for a forward-leaning resting position. However, this design is unstable due to the elongated support on the floor and the soft seat, and its size makes it unsuitable for transport in a backpack or laptop bag.

[0004] WO2011146525A2 describes a portable sleeping device with a headrest and torso support connected by an adjustable axis. The device allows the user to sleep in a forward-facing position while seated, with adjustments to the head and torso position. However, the complex design with multiple moving parts and a ratchet mechanism is expensive to manufacture, bulky to transport, and cumbersome to handle in confined spaces such as airplanes.

[0005] US patent US5645319A describes an inflatable travel pillow that fills the space in front of the passenger and is supported on a surface (e.g., a folding table). It consists of several air chambers that can be individually adjusted. However, this design makes quick adjustments difficult when the front seats move, does not offer sufficient stability for deeper sleep, and requires time and effort to set up and take down.

[0006] US8528970B2 describes an adjustable support device that can be integrated into train seats and provides a forward-tilted resting position by supporting the head, chest, and arms. The device is foldable and size-adjustable. However, it requires installation in the seat in front and is therefore not universally applicable and unsuitable for individual body sizes. Furthermore, vibrations from the train are transmitted from the seat to the body, which would disrupt sleep. Additionally, the device is intended for public use and is not portable, which significantly reduces hygiene. Disadvantages of the state of the art • difficulties in carrying such sleeping devices, • uncomfortable sleeping positions with and without a sleep aid, • complex and / or lengthy setup and dismantling, • unstable and therefore restless sleep • the transmission of the vibrations of the travel vehicle directly to the sleeping device. Object of the invention

[0007] The object of the invention is to overcome the disadvantages of the prior art. According to the invention, these disadvantages are overcome by the sleeping device described in the first, second and third main claims. Description of the invention

[0008] The invention relates to a sleeping device for travelers that is easy to transport. The sleeping device is designed to be foldable and collapsible. In its folded position, the sleeping device is just large enough to fit comfortably into a laptop bag. Furthermore, it is no more than 50 mm thick, preferably no more than 40 mm thick, and most preferably no more than 30 mm thick. "Thicker" here refers to the thickness of the folded sleeping device.

[0009] The sleeping device can be unfolded. To do this, the sleeping device is placed on the legs (thighs) with the leg support or leg plate, and then the body support or lying plate is lifted essentially parallel to the leg plate.

[0010] The sleeping device is essentially constructed like a scissor lift with a hinge. The legs are formed from rectangularly bent tubes, also called tube legs, and are connected along two long sides. In other words, the two tube legs are connected to each other at their midpoints via a hinge joint. It is also conceivable that the legs are not made of tubes, but of solid material. The tube legs can be round, square, or other shapes. The legs can also be open on one side. For the sake of simplicity, all these configurations are referred to as "tube legs."

[0011] The tubular legs are hinged to a plate at one end. They are not connected at the other end of the same tubular leg. This allows the other end to engage with a locking strip or locking element, thus securing it in a fixed position. Furthermore, this design allows the other end to slide along the respective plate. This is also typically used in scissor lifts, although in those cases the other end of the tubular leg is guided longitudinally in a guide.

[0012] The end of the tube leg that slides along the underside of the leg plate when the sleeping device is unfolded can be positioned in a locking element, preferably with several possible locking positions. Meanwhile, the other end slides along the inside of the lying surface, i.e., the side facing away from the sleeping area, and is freely positioned without this end of the tube leg being locked in place. The position of this end of the tube leg is automatically determined by the other three fixed points of the scissor mechanism, specifically by the two fixed points and the point secured by a locking element.

[0013] Now, sleeping position one is reached. This position is essentially similar to sleeping while sitting upright, with your upper body and head resting on a table. Most people remember this from school. However, the sleeping device also allows for a second sleeping position that some may find more comfortable. In this position, the lying platform, which is articulated to a tubular leg, is folded upwards at an angle. One leg, which for clarity will be referred to as the lying platform leg, is attached to the loose end of the tubular leg on which the lying platform rests in sleeping position one. Locking elements are incorporated into the lying platform itself, into which the lying platform leg engages to hold the lying platform at an angle.

[0014] Typical sleeping angles are 30°, 45°, or 60°. However, other angles are also possible. In the second sleeping position, even higher angles are conceivable, for example, 70° or 80°. In the first sleeping position, the lying surface is essentially parallel to the leg support.

[0015] It is also conceivable that the locking positions are recessed or milled into the plates. For example, in the form of a groove into which a section of a pipe leg can engage and be held in position.

[0016] The two platforms (leg and lying platform) are preferably made of wood or plastic, but can also be made of other materials. The platforms can also be covered with fabric and / or padded. It is also conceivable that the platforms differ from each other in their materials and designs.

[0017] The term "essentially planar" refers to a planar plane that is not linear but can also be curved or bent. Therefore, it is conceivable that the plates do not have to be flat.

[0018] In one particular design, the leg plate is made in two parts. The first leg plate rests on a second leg plate and is rotatably mounted opposite the first leg plate, which is also connected to a tubular arm. This has the advantage of widening the narrow side sufficiently for the user to comfortably position it on their thighs.

[0019] The joint connection that connects the pipe legs to each other can essentially be a screw connection or any other type of connection. Position designations 1 lying platform 2 Leg plate 3 pipe legs 4. First sleeping position (parallel) 5 Second sleeping position (angled) 6 Joint connection 7. Collapsed position 8 Extended position 9 lying plate thighs 10 Snap-in element Description of the characters Fig. Figure 1 shows a sleeping device according to the invention in a retracted position and with the lying surface hidden. Fig. Figure 2 shows a sleeping device according to the invention in a retracted position. Fig. Figure 3 shows a sleeping device according to the invention in an extended position and a first sleeping position. Fig. Figure 4 shows a sleeping device according to the invention in an extended position and a second sleeping position in a three-dimensional view. Fig. Figure 5 shows a sleeping device according to the invention in an extended position and in a second sleeping position in a side view. Detailed description of the invention:

[0020] Fig. Figure 1 shows a sleeping device according to the invention in its collapsed position 7. The lying surface 1 is hidden to reveal the interior. The two tubular legs 3 are articulated to the leg plate 2 or the lying surface 1 (not shown). This connection is achieved here with a bent steel sheet. This steel sheet has been drilled and screwed to the respective plate 1, 2 with screws (not shown). Furthermore, two lying surface legs 9 in a resting position and two additional locking elements 10 are visible. The lying surface leg 9 is screwed to the lying surface (not shown) with another bent and drilled steel sheet using screws (not shown). The steel sheet is designed such that the lying surface leg 9 is connected to the steel sheet by a screw connection in such a way that it can be pivoted.The two legs of the lying platform 9 are further glued together with a round wooden rod, so that both legs of the lying platform 9 can be pivoted symmetrically. The locking elements 10 are screwed to the leg plate 2. It can also be seen that the tube legs 3 are only articulated at one of their end faces to one of the two plates 1, 2.

[0021] Fig. Figure 2 shows a sleeping device according to the invention in a collapsed position. Recesses in the lying surface 1 allow the projections of the lying surface legs 9 and the locking elements 10 to extend into these recesses. This has the advantages that, on the one hand, the lying surface leg 9 and the locking elements 10 have more space to hold the tube legs 3 more stably in position, and on the other hand, the overall design can be made flatter.

[0022] Fig. Figure 3 shows a sleeping device according to the invention in an extended position 8 and a first sleeping position 4. The tubular legs 3, which have a hinged connection at the center of their longitudinal side, are extended in an X-shape. It can also be seen that the tubular legs 3 engage in the locking elements 10 on the leg plate 2 and are thus held in position. The lying surface 1 lies flat on the tubular legs 3 and is still pivotable. The leg supporting the lying surface is at rest and is held in a horizontal position against the lying surface 1 by magnets (not shown).

[0023] Fig. Figure 4 shows the sleeping device according to the invention in an extended position 8 with a second sleeping position 5. In this case, the lying plate 1 was raised at an angle and the lying plate leg 9 was attached to the front face of a tube leg 3 with one of its locking positions.

[0024] Fig.Figure 5 shows the sleeping device according to the invention again in an extended position 8 and with a second sleeping position 5, illustrating the complete setup once more. It can be seen that there are several locking positions for the lying platform leg 9 and the locking elements 10, allowing the user to select the height and angle. QUOTES INCLUDED IN THE DESCRIPTION
