Crib railing

Description

TECHNICAL AREA

[0001] The present invention relates to a crib device with at least one crib side having a longitudinal direction and a vertical direction, with rung profile bars extending vertically between an upper longitudinal profile bar and a lower longitudinal profile bar and arranged parallel at intervals in a longitudinally predetermined grid dimension, and connected to the upper and lower longitudinal profile bars, wherein at least one rung profile bar is designed as a slip-through rung profile bar, which is detachably connected between the upper longitudinal profile bar and the lower longitudinal profile bar.

[0002] A removable side rail is typically two or three bars on one side of a crib, especially a baby crib. These bars can be removed to give a growing child more independence and freedom of movement in their bed. From around 15 months of age, when children can usually crawl, stand, and / or walk, removing the bars allows them to easily climb in and out of bed. When the child is asleep, the bars can be reinserted to prevent them from falling out. These removable side rails are therefore designed for everyday use. STATE OF THE ART

[0003] In the applicant's known cot devices, two types of side rail profile bars are used. These side rail profile bars have a round or more rectangular cross-section.

[0004] In the version of the screen with round, passable bars, a spring is embedded in a bore of the upper longitudinal bar. The passable bar sits in bores of the upper and lower longitudinal bars. When the passable bar is pressed upwards into the bore of the upper longitudinal bar using the spring, a pin of the passable bar is released from the lower longitudinal bar. This allows the passable bar to be swung out and removed. The passable bar is reinserted in the same way, but in reverse.

[0005] Once all the slat profile bars are removed, a passage width of 223 mm must be maintained, as specified by a DIN standard. Due to the narrow width of the slat profile bars (approximately 18 mm) and the slat spacing specified by the DIN standard (45 mm to 65 mm), three slat profile bars are used as slat profile bars in conventional cot systems.

[0006] Unlike the round bars used for the lattice profiles, the spring on the rectangular bars used for the wicket bars is not mounted in the bore of the upper longitudinal profile bar, but rather on the wicket bar itself. For a lattice side of this type with the wide wicket bars (approximately 41 mm), only two wicket bars are required to achieve a passage width of 223 mm.

[0007] In both of the known versions described, the springs are mounted at the top, so that to release the slip-bar profile rod, the rod or the springs must be pushed upwards.

[0008] If the springs were mounted at the bottom, there would be a potential risk that children, by grasping the slat profile bar and additionally using their body weight, could push the slat profile bar downwards and thus remove it themselves, which should be avoided.

[0009] The prior art is known in US 3 026 543 A, CN 203 815 048 U and DE 20 2009 011 518 U1. PRESENTATION OF THE INVENTION

[0013] The fitting device described above provides a functional locking and unlocking unit that offers improved and easier handling compared to the prior art, ensures permanently reliable operation, and has a visually unobtrusive appearance while also meeting high design standards. Furthermore, child safety against unintentional unlocking can be guaranteed. In addition, compliance with DIN standards is easily achieved. A particularly preferred embodiment of the crib device according to the invention is characterized in that the fitting device is designed as a bolt unit with a head unit and a bolt shaft. The head unit has an externally accessible handle unit, and the head unit includes a head stop unit that rests against the outer contour of the lower longitudinal profile bar under the action of the elastic spring unit.

[0014] An advantageous design, which is structurally simple and economically feasible and ensures permanently reliable functionality, is characterized by the fact that the elastic spring unit is designed as a helical spring unit arranged around the bolt shaft of the bolt unit.

[0015] A particularly advantageous embodiment with exceptionally high functionality combined with economically justifiable assembly costs during manufacturing is characterized by the fact that the fitting device has a sleeve unit connected to the bolt shaft, on which the elastic spring unit acts and which, in the connected state, is arranged at least partially in a form-fitting manner in the lower slip-bar profile recess, wherein the sleeve unit can be moved downwards by moving the fitting device up to the first spring stop unit, so that it disengages from the lower slip-bar profile recess.In this context, a preferred embodiment is characterized by the fact that a screw projection with an external thread is connected to the bolt shaft of the fitting device in its upper end region, onto which the bolt sleeve with an internal thread is screwed, wherein the bolt sleeve has a second spring stop unit for the elastic spring unit.

[0016] With regard to economical manufacturing, a particularly advantageous design is characterized by the fact that the continuous recess is designed as a stepped recess, wherein the step formed by the stepped recess serves as the first spring stop unit for the spring unit.

[0017] Preferably, the handle unit is designed as a head unit arranged on the bolt shaft, which advantageously has a continuous recess to which, for example, a loop unit or lever unit is connected to facilitate the pulling movement of the fitting device to release the slip bar profile bar.

[0018] High design quality allows for a preferred configuration characterized by the handle unit having a spherical, hemispherical, elliptical, plate-like or slab-like volume contour.

[0019] This design, with the head unit serving as a handle featuring the aforementioned contoured shape, offers the further advantage that children playing, for example, crawling under the bed, will not injure themselves. A leather ring, a fabric strap, or something similar can be threaded through the hole in the head unit to provide a secure grip. These strap solutions also have the advantage of being less prone to snagging.

[0020] Alternatively, an eyelet with a fixed handle can be mounted in the recess of the head unit of the fitting. This has the advantage that the handle can be folded away through the eyelet to avoid the risk of injury.

[0021] A particularly preferred embodiment, which ensures the implementation of very good grip properties, is characterized by the fact that a head shaft unit is molded onto the grip unit of the head unit, at the end of which the head stop unit is arranged.

[0022] A particularly preferred embodiment is characterized by the fact that the head unit with its shaft is made of a dimensionally stable, elastically deformable material, especially plastic. Thermoplastic elastomer is preferably used as the material. In this embodiment, the handle unit with its head and shaft is dimensionally stable on the one hand, to ensure that the closure can be opened as a handle, and on the other hand flexible and elastic to mitigate and prevent accidental contact, for example, by crawling and playing children. Furthermore, the elastic compliance reduces the possibility of objects getting caught on the handle unit.

[0023] The shape of the handle unit, including the head and shaft, combines and supports the aforementioned features. Firstly, the handle unit is shaped for easy gripping when opening, and secondly, it features a narrow waist to ensure flexibility and elasticity. This elasticity, along with the thickened section of the handle unit below the waist, which forms the head with a downward-sloping shape, reduces the risk of snagging.

[0024] A particularly simple design solution that guarantees high haptic functionality is characterized by the fact that the head shaft unit has a linear, in particular straight, or straight or concave cross-sectional contour that tapers downwards or upwards.

[0025] The fitting device can preferably be made of metal, aluminum or plastic.

[0026] To ensure the required DIN widths for exiting or entering within the side of the crib for the children, several, in particular two, three, four, five or more, slip-out bar profile bars, especially immediately adjacent ones, are preferably present.

[0027] The cross-sections of the rung profile bars or slip rung profile bars are preferably designed as round profiles, elliptical profiles, polygonal profiles, in particular square or rectangular profiles.

[0028] A particularly preferred embodiment of the cot device according to the invention is characterized in that the cot device has a cot side running around each side of the bed, or on two opposite sides of the bed, or on one side of the bed.

[0029] To ensure lasting functionality, a particularly advantageous further development is characterized by the fact that the upper form-locking unit / projection unit of the slip-bar profile bar has a conically tapered cross-sectional contour.

[0030] According to a further advantageous development, the permanently reliable functionality is ensured by the fact that the bolt sleeve of the fitting device has a conical cross-sectional reduction in its upper free end area.

[0031] An advantageous embodiment is characterized in that the fitting device has a screw unit that penetrates the sleeve unit and is screwed to an internal thread of the hollow profile-shaped bolt shaft.

[0032] Another advantageous embodiment is characterized by the fact that the bolt shaft of the fitting device is designed as a screw shaft with an external thread, and the sleeve unit has a sleeve shaft with an internal thread into which the screw shaft of the bolt shaft is screwed.

[0033] A particularly advantageous and simple design with regard to assembly, which does without a screw connection, is characterized by the fact that the bolt shaft of the fitting device is designed as a hollow profile with locking recesses, and elastic locking profiles with locking projections pointing downwards are formed onto the sleeve unit, which engage in the locking recess of the bolt shaft in a form-fitting manner.

[0034] An alternative design, which is designed without the formation of screw connections, is characterized by the fact that elastic locking profiles with locking projections are formed on the upper side of the bolt shaft of the fitting device, which are positively connected to the sleeve unit.

[0035] Another advantageous alternative embodiment, which has a structurally simple design, is characterized by the fact that the bolt shaft of the fitting device has a transverse shaft recess in its upper end area, the sleeve unit has a continuous transverse sleeve recess in its upper end area, and a continuous cotter pin unit for connecting the bolt shaft and sleeve unit is arranged in the transverse shaft recess and the transverse sleeve recess.

[0036] The method for releasing a slip-bar profile bar on a grid side of a grid bed device described above is characterized by the following method steps for releasing the slip-bar profile bar: • Move the fitting downwards vertically, thereby releasing the positive-locking connection between the lower longitudinal profile bar and the slip-bar profile bar, and move the slip-bar profile bar laterally away from the lower longitudinal profile bar. • Release the positive-locking connection between the upper longitudinal profile bar and the upper positive-locking / projection unit of the slip-bar profile bar by pulling it out. • Remove the slip-bar profile bar.

[0037] The method for connecting a slip-bar profile bar to a grid side of a grid bed device described above is characterized by the following method steps for connecting the slip-bar profile bar: • Insert the upper positive locking unit / projection unit of the wicket bar profile bar into the underside recess of the upper longitudinal profile bar. • Move the fitting downwards. • Pivot the wicket bar profile bar until the underside wicket bar profile bar recess is positioned above the continuous recess of the lower longitudinal profile bar. • Release the fitting, causing it to move upwards due to the action of the elastic spring unit, creating a positive locking connection between the upper end of the fitting or the bolt sleeve and the underside wicket bar profile bar recess, thus securing the wicket bar profile bar in a childproof manner.

[0038] Such a method, through the functional locking solution according to the invention, enables improved and easy handling, ensures a high level of child safety and allows for the easy implementation of existing DIN standards.

[0039] Further embodiments and advantages of the invention become apparent from the features further listed in the claims and from the exemplary embodiments given below. The features of the claims can be combined with one another in any way, provided they are not obviously mutually exclusive. BRIEF DESCRIPTION OF THE DRAWING

WAYS TO IMPLEMENT THE INVENTION

[0041] In Fig. 1 Figure 10 shows an embodiment of a crib device 10 in a perspective view, which, viewed from above, has a rectangular perimeter contour with a vertically extending bedpost 11 arranged in each of its corner regions. A crib side 12 is arranged on each of the two longitudinal sides and each of the two end faces of the crib device 10. Each crib side 12 has rung profile bars 14 arranged between an upper longitudinal profile bar 16 and a lower longitudinal profile bar 18, extending vertically H and parallel to each other in a horizontal longitudinal direction L at a predetermined grid spacing.

[0042] The in Fig. 1 The front side of the crib 12 facing the viewer has three rung profile bars symmetrically arranged around its center, which are designed as slip-out rung profile bars 20, meaning that the slip-out rung profile bars 20 can be removed from the crib side 12 or inserted into the crib side 12 as required.

[0043] Below each slip-bar profile bar 20 a fitting device 30.1 is arranged, which enables the removal or insertion of the slip-bar profile bar 20 and is described below.

[0044] In the illustrated embodiment, the rung profile bars 14 and the slip-gate rung profile bars 20 are designed as rectangular profile bars. They can also have a different cross-sectional profile, such as a round, polygonal, square, or other differently shaped cross-sectional profile.

[0045] In Fig. 2 A section of a slip-bar profile 20 between an upper longitudinal profile bar 16 and a lower longitudinal profile bar 18 is shown in an exploded view without the fitting device 30.1.

[0046] The upper longitudinal profile bar 16 has a downwardly open, blind-hole-like recess 22 on its underside. The lower longitudinal profile bar 18 has a recess extending through the vertical direction H, which is designed as a stepped recess 28. The stepped recess 28 has an upper section with a diameter D1 and a lower section with a diameter D2, the diameter D2 being smaller than the diameter D1, so that a first spring stop unit 38 is located inside the stepped recess 28.

[0047] The slip-bar profile 20 has an upper form-locking unit in its upper end area, which is designed as a projection unit 24 and which can be inserted in a form-locking manner into the lower recess 22 of the upper longitudinal profile bar 16 (arrow E).

[0048] On its underside, in its lower end area, the slip-bar profile bar 20 has a slip-bar profile bar recess 26 which is open downwards.

[0049] The Fig. 3 Figure 1 shows a cross-sectional detail of the positive-locking connection of the slip-bar profile 20 to the lower longitudinal profile 18. By means of the fitting device 30.1.

[0050] The fitting 30.1 has a head unit 32 in its lower end region, which includes a handle unit 39 and is hemispherical in the illustrated embodiment. A bolt unit 34, extending upwards in the vertical direction H, is integrally formed on the head unit 32 and passes through the interior of the continuous recess 28 of the lower longitudinal profile bar 18. A screw projection 46 with an external thread is integrally formed on the upper end region of the bolt unit 34. A sleeve unit 44 with an internal thread is screwed onto the screw projection 46. The sleeve unit 44 projects partially into the lower slip-gate profile bar recess 26, ensuring a positive-locking connection.

[0051] Furthermore, the sleeve unit 44 has a second spring stop unit 48. An elastic spring unit 36 ​​rests against this second spring stop unit 48, helically surrounding the bolt shaft 40, with its lower end resting against the first spring stop unit 38 of the stepped recess 28. Thus, the fitting 30.1 is under the spring tension of the elastic spring unit 36, ensuring that the sleeve unit 44 engages positively in the lower recess 26 of the sliding bar profile and that the head unit 32 of the fitting 30.1 is pulled onto the underside of the lower longitudinal profile bar 18. This provides a child-safe, positive-locking connection between the sliding bar profile bar 20 and the lower longitudinal profile bar 18.

[0052] The spring unit 36 ​​can also have a different design. Its function is important, namely that it pulls the head unit 32 of the fitting device 30.1 to the underside of the lower longitudinal profile bar 18 and presses the sleeve unit 44 into the underside recess 26 of the slip-bar profile bar.

[0053] The first spring stop unit 38 can also have a different design. It is important that the first spring stop unit 38 is arranged on the lower longitudinal profile bar 18 and forms a stop for the spring unit 36, and that a counter-stop (second spring stop unit 48) is simultaneously present on the fitting device 30.1.

[0054] In the illustrated embodiment according to Fig. 3 The handle unit 39 has a continuous transverse recess 42 to which a belt unit or lever unit (not shown) can be connected to improve the manual graspability of the handle unit 39.

[0055] To release the connection between the lower longitudinal profile bar 18 and the slip-bar profile bar 20, the fitting 30.1 is pulled downwards in the direction of arrow A (extension direction) by pulling the handle unit 39 until the lower end face of the sleeve unit 44 with the first spring stop unit 38 comes to rest within the stepped recess 28. This disengages the sleeve unit 44 with the lower slip-bar profile bar recess 26, allowing the slip-bar profile bar 20 to be pivoted outwards. By pivoting the slip-bar profile bar 20 away, it is possible to release the positive locking connection of the upper longitudinal profile bar 16 with the projection unit 24 of the slip-bar profile bar 20 (see Fig. 9 ), so that the slip-bar profile bar 20 can be easily removed overall.

[0056] The insertion of the slip-bar profile 20 is carried out in reverse order. First, the projection unit 24 of the slip-bar profile 20 is inserted into the underside recess 22 of the upper longitudinal profile bar 16 (see arrow E in Fig. 2 Then the fitting device 30.1 is pulled downwards from the outside against the action of the spring unit 36 ​​by grasping the handle unit 39 (arrow A in Fig. 3 ) and then the pass-through profile bar 20 is pivoted with its lower end region until the underside pass-through profile bar recess 26 is positioned above the continuous recess 28 of the lower longitudinal profile bar 18. As soon as this position is reached, the fitting device 30.1 is released, causing it to move upwards due to the spring action of the spring unit 36, so that the sleeve unit 44 engages positively in the underside pass-through profile bar recess 26. A child-safe connection of the pass-through profile bar 20 is then ensured.

[0057] To facilitate the insertion of the projection unit 24 into the lower recess 22 of the upper longitudinal profile bar 16, the projection unit 24 has a conical cross-sectional taper in its end region.

[0058] Furthermore, the sleeve unit 44 also has a conical cross-sectional reduction in its upper area to facilitate the insertion of the sleeve unit 44 into the lower slip-bar profile bar recess 26 of the slip-bar profile bar 20.

[0059] The fitting device 30.1 shown in the exemplary embodiment can also be designed in a different way. A key feature of a differently designed fitting device 30.1 is that it can be pulled downwards against a spring force, in particular until it reaches a stop, thereby releasing the positive fit between the slip-bar profile 20 and the lower longitudinal profile 18, allowing the slip-bar profile 20 to be pivoted out. Then, by releasing the positive fit between the projection unit 24 and the upper longitudinal profile 16, the slip-bar profile 20 can be easily removed.

[0060] The Fig. 4 shows a detailed sectional view of the crib side 12 according to Fig. 1 in the area of ​​two slip-bar profile bars connected to the lower longitudinal profile bar 18, each with a fitting device 30.1.

[0061] The Fig. 5 shows a detailed perspective view according to the detailed section view of Fig. 4 in the partially cut-open state of the lower longitudinal profile bar 18 in the area of ​​a fitting device 30.1.

[0062] The Fig. 6 supplements the presentation according to Fig. 5 with an extended cut-out section of the fitting device 30.1, so that the screw projection 46, onto which the sleeve unit 44 is screwed, is visible.

[0063] The Fig. 7 shows the state starting from Fig. 6 in which the fitting device 30.1 is pulled downwards and the sleeve unit 44 is out of engagement with the underside slip bar profile bar recess 26.

[0064] The Fig. 8 shows the condition according to Fig. 7 with the slip-bar profile bar 20 partially swung out.

[0065] The Fig. 9 shows in a detailed perspective the state in which the projection unit 24 of the slip-bar profile rod 20 is pulled out of the lower recess 22 of the upper longitudinal profile rod 16, thus making it easy to remove the slip-bar profile rod 20.

[0066] The Figuren 10 bis 14 Figures 30.2, 30.3, 30.4, 30.5, 30.6 show different design variants of fitting devices 30.2, 30.3, 30.4, 30.5, 30.6 in exploded perspective view with a sleeve unit 44 and a spring unit 36 ​​surrounding the bolt shaft 40.

[0067] The Fig. 10 Figure 1 shows an embodiment of a fitting device 30.2 in which the head unit 32 is designed as a hemispherical handle unit 39 with a transverse recess 42, onto which a bolt shank 40 is integrally formed. The bolt shank 40 is designed as a hollow profile with an internal thread. A sleeve unit 44 is positively fitted onto the bolt shank 40 from above, and the sleeve unit has a central through-hole 62. A screw unit 50 is inserted through this through-hole 62 from above, and its external thread is screwed into the internal thread of the bolt shank 40. The elastic spring unit 36 ​​is arranged extending around the bolt shank 40 and runs in certain areas between the inner wall of the sleeve unit 44 and the outer wall of the bolt shank 40.

[0068] The Fig. 11 Figure 3 shows a further embodiment of a fitting device 30.3 according to the invention, featuring a hemispherical head unit 32 and a handle unit 39. The bolt shank 40 is designed as a screw shank with an external thread. The sleeve unit 44 has a downwardly extending sleeve shank 45 with an internal thread, the sleeve shank 45 having a smaller outer diameter than the sleeve unit 44. To connect the components, the bolt shank 40 is screwed into the sleeve shank 45. This solution is particularly suitable for manufacturing as an injection-molded plastic component.

[0069] The Fig. 12 Figure 1 shows a further embodiment of a fitting device 30.4 with a hemispherical head unit 32 or handle unit 39 with a transverse recess 42 and a hollow cylindrical bolt shaft 40 integrally formed thereon, which has locking recesses 52 in its wall at its lower end. Elastically compliant locking profiles 54, pointing downwards, are integrally formed on the underside of the sleeve unit 44 and have locking projections 56 at their lower end. The locking profiles 54 of the sleeve unit 44 are inserted into the interior of the bolt shaft 44 until the locking projections 56 engage in the locking recesses 52 of the bolt shaft 40, thus ensuring a secure connection between the sleeve unit 44 and the bolt shaft 40. In this embodiment, the sleeve unit 44 is designed as a cup-shaped sleeve unit.

[0070] Fig. 13 Figure 1 shows a further embodiment with a snap-fit ​​connection in which upwardly pointing snap profiles 58 with end-mounted snap projections 60 are integrally formed on the upper side of the bolt shank 40. The sleeve unit 44 is designed as a hollow profile sleeve, so that, to connect the bolt with bolt shank 40 to the sleeve unit 44, the snap profiles 58 are guided through the sleeve unit 44 until their snap projections 60 engage with a snap-fit ​​unit 64 of the sleeve unit 44, thus ensuring a secure connection between the sleeve unit 44 and the bolt shank 40. The snap-fit ​​unit 64 of the sleeve unit 44 is formed by a stepped recess in the upper end region of the sleeve unit 44.

[0071] The Fig. 14 Figure 1 shows an alternative embodiment of a fitting device 30.6 with a cotter pin connection between the sleeve unit 44 and the bolt shank 40. The bolt shank 40 has a transverse recess 41 in its upper end region. A transverse recess 47 is provided on both sides of the wall of the sleeve unit 44 in its upper edge region. For connection, the sleeve unit 44 is slid onto the bolt shank 40, positioned such that the transverse recess 41 and the transverse recess 47 are aligned. A cotter pin 70 is then inserted transversely into the recesses 41 and 47 to connect the two components. In the illustrated embodiment, the cotter pin 70 is designed as a slotted cylindrical hollow profile.

[0072] The Fig. 15 Figure 1 shows an alternative embodiment of a crib device 10.2, in which both longitudinal sides of the crib device 10.2 each have a bed side 12 and plate-shaped bed heads 13 are provided at the end faces, to which the crib sides 12 are connected. The in Fig. 15 The side of the crib facing the viewer 12 has three slip-bar profile bars 20 with a fitting device 30.1 arranged symmetrically around its center.

[0073] The Figuren 16a, b bis 21a, b Figure 1 shows different embodiments of the design of a head unit 32 with a handle unit 39, wherein a head shaft unit 35 is arranged between the head stop unit 33 and the handle unit 39. This means that the head unit 32 is spaced apart from the head stop unit 33, which in principle facilitates the tactile handling of the head unit 32 for grasping and thus for performing the release movement. The bolt shaft 40 is integrally formed on the upper side of the head stop unit 33. The head unit 32, handle unit 39, head shaft unit 35, head stop unit 33, and bolt shaft 40 are designed as a single-piece component.

[0074] This shows Figuren 16a, b an embodiment in which the head unit 32 is essentially spherical and the head shaft unit 35 has a concave cross-sectional contour in the form of a waist.

[0075] Preferably, the handle unit 39 with head unit 32 and head shaft unit 35 is made of elastic material, for example, thermoplastic elastomer. This allows the handle unit 39 to perform an evasive movement B if necessary. This design makes the handle unit 39 with head unit 32 and head shaft unit 35 dimensionally stable, ensuring the opening of the closure, while also being flexible and elastic, mitigating and preventing impacts, for example, by crawling and playing children. Furthermore, the elastic compliance reduces the possibility of objects getting caught on the handle unit 39.

[0076] The shape of the handle unit 39, with its head unit 32 and head shaft unit 35, combines and supports the aforementioned properties. Firstly, the handle unit 39 is shaped to be easy to grip for opening, and secondly, it features, for example, a narrow waist to ensure flexibility and elastic compliance. This elastic compliance, along with the thickened area of ​​the handle unit 39 located below the waist and designed as the head unit 32 with a downward-sloping shape, reduces the possibility of snagging.

[0077] In the embodiment according to the Figuren 17a, b , which is fundamentally similar in design to the embodiment according to the Figuren 16a, b , the handle unit 39 has a more elliptical volume circumference contour.

[0078] The Figuren 18a, b und 19a, b Figure 1 shows embodiments in which the head shaft unit 35 has a cross-sectional contour that tapers straight downwards, and the handle unit 39 has an elliptical or plate-shaped volume contour.

[0079] The Figuren 20a, b show an embodiment in which the handle unit 39 is designed as a spherical shape and the head shaft unit 35 has a straight cross-sectional profile, i.e., is cylindrical.

[0080] A similar design is also found in the embodiment according to the Figuren 21a, b on, with the handle unit 39 having a pyramidal volume contour.
