Abstract
Description
Technical Field
[0001] The invention relates to a baby cradle hook system for connecting a movable baby cradle to a retaining element, a spring cradle system for infants or young children, and the use of a baby cradle hook system in a spring cradle system for infants or young children. Background Art
[0002] Children's cradles for accommodating infants or young children therein are known. Thus, such spring cradles can be used as sleeping places for infants. It has proven to be particularly advantageous if the spring cradle performs certain movements. In this case, the infant feels particularly good, calms down and falls asleep easily. However, in the case of movement of elements, there is always the risk of causing failures of individual components, which can be particularly dangerous in connection with infants or young children. In particular, the interface between the moving elements of the spring cradle and the elements fixed relative to it causes certain potential risks, for example due to spalling in metal-metal contacts. In order to ensure a wide range of fields of use of the spring cradle (for example for infants or young children of different weights or sizes), it is desirable that individual components of such a spring cradle can be replaced without problems by the end user. Summary of the invention
[0003] It is therefore an object of the present invention to provide a connection system between a movable part of a spring cradle and a part of the spring cradle fixed relative thereto which provides a secure connection while still enabling replaceability.
[0004] The invention solves this problem by means of a cradle hook system having the features of claim 1 , by means of a spring cradle system having the features of claim 10 , and by means of the use of a cradle hook system having the features described below.
[0005] According to one aspect of the present invention, a baby cradle hook system is provided for connecting a movable baby cradle to a retaining element in a main direction. The hook system may include a first hook section having a first retaining area for retaining a retaining portion of the baby cradle. The hook system may include a second hook section having a second retaining area for retaining a retaining portion of the retaining element having a rectangular cross section and having a second introduction area for introducing the retaining portion of the retaining element into the retaining area. The second retaining area may be designed so that the retaining portion of the retaining element can only be retained in the retaining area in a first orientation. The second introduction area may be designed so that the retaining portion of the retaining element can only pass through the introduction area in a second orientation along an introduction direction. Preferably, the first orientation and the second orientation are different.
[0006] According to this, a reliable connection between the movable baby cradle and the holding element fixed relative thereto can be achieved by means of the hook system. Therefore, more precisely, it may be necessary that the hook system is twisted around / along a specific axis or curve in order to remove the holding portion of the holding element from the second hook section. Due to the defined relative movement between the holding portion of the holding element and the hook section, the hook system itself can be prevented from loosening. Therefore, the safety of the connection between the baby cradle and the holding element can be improved. In addition, the possibility of the hook system still being loosened from the holding element due to a specific movement can ensure a simple replaceability of the hook system and / or other components. Therefore, the operability can be improved as a whole.
[0007] A movable baby cradle or spring cradle can be a basket structure, a cloth structure or a baby hammock, etc., in which a baby or a young child can be loaded. In addition, the baby cradle can include elastic elements such as springs, etc. In this way, the spring can be placed under stress by the weight of the baby cradle or the baby contained therein, so that the spring element deflects. In other words, the elastic element can be elastically deformed. By the external force applied subsequently (for example, by a drive unit or by a user), the baby cradle can swing. Therefore, the baby cradle can be referred to as a movable element. In other words, the baby cradle can move up and down along the direction of gravity during operation. The holding element of the baby cradle can, for example, be a bow-shaped piece at the elastic element. Therefore, the baby cradle can be connected to the hook system by means of the elastic element. The hook system can also be fixed at the holding element, thereby the baby cradle can be held. The elastic element (for example, spring element) of the baby cradle can be replaceable. In this way, a matching elastic element can be used based on the weight of the baby so that the optimal operation of the spring cradle can be achieved. The movable baby cradle can be connected to the holding element along the main direction. The main direction can basically correspond to the direction of gravity here. The first and second hook sections can be designed to absorb loads. The first and second hook sections can be designed so that in the engaged state (i.e. the state in which one connection fitting is accommodated in the first hook section and the other connection fitting is accommodated in the second hook section) the baby cradle and the retaining element are held so that they cannot be released from each other in the main direction. The first hook section can be a substantially curved J-shaped section. The retaining portion of the baby cradle (e.g. a part of the elastic element) can be accommodated and retained in the first hook section. Retention can mean that the retaining portion is fixed in position or is fixed in position and is fixed in the first hook section (more precisely in the first retaining area). As a result, the elastic element can be loaded in the main direction without releasing the connection between the baby cradle and the hook system. The second hook section can be a substantially curved J-shaped section. The second hook section can have a second retaining area for retaining the retaining portion of the retaining element. The retaining portion of the retaining element can have a substantially rectangular cross section, but the cross section can preferably have a rounded portion determined by production. In other words, the holding portion of the holding element can have a polygonal body with defined corners (i.e. without roundings not determined by production or without roundings with a radius greater than 2 mm). The orientation of the holding portion of the holding element is therefore defined by the hook system when introduced into the hook system and when held. In other words, there can be only one orientation of the holding portion relative to the second hook section in which the holding portion can be introduced into the second hook section and held in the second hook section. The holding element can be a web which has a polygonal cross section in its cross section. The second holding region of the second hook section is dimensioned in such a way that the holding portion of the holding element can be held in the holding region in exactly one orientation.The second introduction area of the second hook section can be an access opening to the holding area. In other words, the holding portion of the holding element must be guided through the introduction area in order to reach the holding area. If the holding portion of the holding element arrives in the holding area, the holding portion of the holding element can be located in the final position. The position of the holding portion of the holding element in the introduction area of the second hook section can be referred to as the introduction position. The hook system can be a plate-like element extending in the first hook plane. The holding element can be a plate-like element extending in the holding element plane. When the hook system and the holding element are assembled together, the first hook plane and the holding element plane can be substantially perpendicular to each other (i.e. not only in the final position but also in the introduction position). Basically, it means here that a deviation of ±5° is still considered to be perpendicular. The hook system can have a second hook plane, which is perpendicular to the first hook plane. In addition, the hook system and the holding element can work together or be designed so that the second hook plane is parallel to the holding element plane in the introduction position and perpendicular to the holding element plane in the final position. It can therefore be achieved that the hook system and the holding element must move relative to each other in a specific manner and method in order to form a connection between the holding element and the hook system. The holding portion can have its maximum extension in the holding element plane. In particular, the holding element plane and the second hook plane can be pivoted by about 90° between the final position and the introduction position, wherein "about 90°" includes a deviation of ±5°. After pivoting (for example, after reorienting the holding portion of the holding element), the holding portion can be introduced in the holding area of the second hook section. If the holding portion of the holding element is arranged in the second holding area, the holding portion of the holding element can be prevented from pivoting by the configuration of the holding area, wherein "pivoting" preferably means pivoting greater than ±5°. In other words, in the final position of the holding portion, the holding portion can be prevented from returning to another orientation. Nevertheless, the holding area can be designed so that the holding element plane and the second hook plane can be pivoted by up to ±20°. This can prevent these hook systems from getting stuck when multiple hook systems are arranged side by side. The design of the hook system can prevent the holding portion of the holding element from being undesirably loosened. In other words, the orientation of the holding element plane and the second hook plane (i.e. the orientation of the holding portion and the orientation of the hook element relative to each other) can be referred to as orientation. Thus, a hook system can be provided which can reliably prevent an unintentional release from the holder, but nevertheless allows a separation of the mating connection element without problems in the case of a defined movement.
[0008] Preferably, the first orientation and the second orientation differ in their angular position with respect to the main direction, preferably perpendicularly. In other words, the first orientation of the retaining portion of the retaining element relative to the second hook section can differ from the second orientation in terms of torsion. The angular position can be defined between the retaining element plane and the second hook plane. In simple terms, the element can pass through the second introduction area in an orientation that can be different from the orientation in which the element is retained in the second retention area. The expression that the angular position is defined perpendicularly to the main direction preferably indicates that the two degrees of freedom are the same in the first orientation and in the second orientation. It can therefore be ensured that the introduction area can only be passed by the retaining portion of the retaining element when the retaining portion of the retaining element is oriented in the second orientation. It is therefore possible to prevent the retaining portion of the retaining element and the second hook section from being undesirably loosened. As a result, the safety of the connection can be improved.
[0009] Preferably, the first orientation and the second orientation differ by at least 45°, preferably by at least 60°, more preferably by approximately 90°. When the first orientation and the second orientation differ by at least 45°, it can be ensured that the second hook section or the holding part of the holding element must be relocated or moved so that the two can be released from each other. It can thus be avoided that the holding part of the holding element and the second hook section are released from each other undesirably by the usual clearance and / or tolerance. In addition, a certain clearance can be provided so that the hook system can be prevented from getting stuck. In the case of electrically driven baby cradles, it has been proven that an angle difference of at least 60° is advantageous. This is due to the following reasons, because the spring cradle that accommodates the baby is actively moved in the vertical direction (i.e. in the direction of gravity) by the drive unit, which can cause a large deviation of the hook system. In the case of an angle difference of at least 60°, it can be ensured that the connection between the second hook section and the holding part of the holding element is also released under this movement. In the case of an angle difference of approximately 90°, it can also be ensured that an undesired operation (for example by the siblings of the baby accommodated in the baby cradle) releases the hook system from the holding element. In other words, in the case of an angular difference of approximately 90°, a defined movement of the hook system may be necessary in order to release the hook system. Approximately 90° may mean that there is an angular difference of ±5° from 90°. Thus, manufacturing can be simplified, since effective tolerances can be utilized.
[0010] Preferably, the second holding region is spaced apart from the second introduction region in the main direction. In other words, the holding portion of the holding element and the hook system move relative to each other in the opposite direction to the direction of gravity (i.e. in the main direction) in order to release from each other. It can thus be ensured that the system remains in the connected state by loading the hook system. Only in the case of a reaction force (i.e. in the opposite direction to the direction of gravity) can the hook system (i.e. the second hook section) be moved in such a way that the holding portion of the holding element can reach the introduction region. This further increases the safety against undesired release.
[0011] Preferably, the second introduction region is designed such that the introduction region is perpendicular to the main direction. In other words, according to the present aspect of the invention, the holding part of the holding element and / or the hook system must be moved relative to one another so that the holding part moves laterally in the introduction direction. As a result, the introduction and withdrawal of the holding part of the holding element into the second hook section takes place in a different direction than the direction of the load application. As a result, the elements can be assembled more easily and held securely when loaded.
[0012] Preferably, the first hook section has a first introduction area for introducing the holding portion of the baby cradle into the first holding area, and preferably the first introduction area has a larger introduction cross section than the second introduction area. A part of an elastic element (e.g. a spring) can be introduced into the first holding area of the first hook section. The elastic element can be fastened at the hook system by means of an external fastening device, for example. It is therefore unnecessary to design the first introduction area of the first hook section so that the holding portion can only be passed through in a specific orientation. Instead of this, it may be sufficient to design the first introduction area so that the holding portion of the baby cradle can be introduced without problems in order to reach the holding area. The operation of the entire system can thereby be simplified. In addition, elastic elements of different designs can also be used, which, for example, have a holding portion that is determined to be larger in size.
[0013] Preferably, the first introduction area and the second introduction area are oriented in the same direction, particularly perpendicular to the main direction. In other words, the first introduction area and the second introduction area can have an opening pointing in the same direction. Thus, the operation of the entire system can be simplified because two introduction openings can be operated from the same direction.
[0014] Preferably, the first holding region and the second holding region are located in a straight line in the main direction. This allows a particularly favorable force flow direction through the hook system to be achieved, since the forces introduced by the holding section of the baby cradle can be directly transferred to the holding section of the holding element. This prevents bending of the hook system, thereby improving the durability of the hook system.
[0015] Preferably, the second hook section can have a rotation area between the introduction area and the holding area, wherein the rotation area is preferably designed so that the second holding portion of the second element can be changed from the first orientation to the second orientation. In other words, a further area can be provided between the introduction area and the holding area of the second hook section, which is designed so that the holding portion of the holding element and the second hook section can be twisted relative to each other. In particular, in the rotation area, the holding element plane and the second hook plane can be twisted relative to each other. Thus, the holding portion of the holding element can be changed from the introduction position to the holding position. In addition, the transition between the rotation area and the second holding area can taper gradually. The area between the holding areas in the rotation area can be rounded so that the rectangular holding portion of the holding element can be advantageously twisted relative to the second hook section in the rotation area, appropriately around an axis perpendicular to the main direction. Therefore, the rotation area can ensure that the holding portion of the holding element can be changed from the first orientation to the second orientation within the second hook section. It can be ensured thereby that the connection between the second hook section and the holding portion of the holding element is prevented from being undesirably loosened.
[0016] Preferably, the rotation region has a larger dimension perpendicular to the main direction than the second holding region. In other words, the rotation region can have a larger dimension than the holding region, so that the holding portion of the holding element can be arranged in the rotation region not only in the first orientation but also in the second orientation. The rotation region can thus be represented as a transition region between an introduction region, in which the holding portion of the holding element can only be arranged in the second orientation, and a holding region, in which the holding portion of the holding element can only be arranged in the first orientation. In contrast, the second holding region can have a constant clear width along the main direction, so that a shape of the second holding region that matches the holding portion is achieved, so that the holding portion of the holding element cannot be twisted in the second holding region.
[0017] Preferably, the hook system is designed asymmetrically in the main direction and / or perpendicular thereto. The asymmetrical design of the hook system ensures that two hook sections cannot be released simultaneously by a movement of the hook system relative to the holding part of the holding element and / or the holding part of the baby cradle. This improves the safety of the system as a whole.
[0018] Preferably, the hook system has a web section which separates the first hook section from the second hook section. The web section can define the first introduction area and / or the second introduction area. In addition, the web section can prevent the retaining part from directly transitioning from one retaining area to another retaining area. It can thus be ensured that each retaining part must first be guided through the introduction area. This ensures that the retaining part cannot be released from the retaining area unintentionally.
[0019] Preferably, the hook system has a through-hole which is designed to accommodate a fastening element. Thus, an additional fastening element can be provided in order to prevent the baby cradle from falling in the event of a failure of the connection between the first hook section and / or the second hook section and the respectively associated retaining portion. According to one aspect, a through-hole can be provided at the hook system on the side of the first hook section, so that the baby cradle can be additionally fixed to the through-hole of the hook system by means of a fastening element, for example a fastening cord. Thus, the baby cradle can also be securely held at the hook system in the event of a failure of the elastic element and / or the first hook section.
[0020] Preferably, the through-hole is located in a line with the first holding area and / or the second holding area. This ensures that, in the event of a sudden load on the fastening element, the load can be reliably removed via the hook system. This is the case in particular when the points of force application (i.e. the through-hole and, for example, the second hook section) are located in a straight line. Preferably, the direction of the straight line corresponds to the direction of gravity. This avoids moments and the like. Moments can occur when the through-hole is not located in a straight line, which preferably extends in the direction of gravity. In these cases, deflections can result, which can cause undesired lateral swings of the system.
[0021] Preferably, the hook system has a substantially rectangular cross section in a cross section perpendicular to the main direction. Preferably, the hook system can be formed by a curved or straight rod element. The rod element can have a substantially rectangular profile cross section. Basically here means that the edges can also be designed in a chamfered or rounded manner. This can improve the feel of the hook system. The rectangular cross section can prevent the hook element from twisting relative to the holding part. In particular, an anti-twist device can be advantageous in the holding part of the holding element, because this ensures a more secure holding.
[0022] Preferably, the first hook section and the second hook section are integrally formed. Integrally here can mean that the first hook section and the second hook section are formed in one piece (ie from one material). Integrally can mean that the first hook section and the second hook section cannot be released from each other without destruction. This can simplify production and improve retainability.
[0023] Preferably, the hook system has a covering element, which can be fixed in the first holding area so that the first introduction area is closed by the covering element. The covering element can be a separate component, which can be releasably placed at the hook system. Here, the hook system and the covering element can be designed according to the key lock principle so that the covering element can only be arranged at the hook system in a specific position. The closure of the introduction area can mean that the holding portion of the baby cradle can no longer be removed from the first hook section without removing the covering element from the hook system. Therefore, the safety of the holding portion of the baby cradle from coming out can be improved. The covering element can be fixed to the holding system, for example, by means of a clip mechanism. The covering element can be formed by an elastic material. In this case, the clip mechanism can be particularly simple to implement. Preferably, the covering element is configured so that the covering element can only (i.e. only) be fixed in the first holding area. In other words, the covering element can be unfixable in the second holding area. Therefore, incorrect operation of the hook system can be excluded.
[0024] Preferably, the covering element is made of a different material than the first hook section. This makes it possible to avoid contact between the same materials of two different elements. This makes it possible to avoid contact corrosion on the one hand and noise generation on the other hand. More precisely, increased wear can occur due to the collision of similar materials with each other. In addition, the covering element can have shock-absorbing properties, since the first hook section and the second hook section are decisively responsible for the stability of the hook system. Thus, even when the baby cradle and thus the holder of the baby cradle are moved, quiet operation can be ensured, since the cover can dampen all movements of the holder of the baby cradle.
[0025] Preferably, the covering element has a holding device for holding the holding portion of the baby cradle. In other words, when the covering element is fixed at the first hook section, the covering element accommodates the holding portion of the baby cradle. Therefore, the holding portion of the baby cradle can only indirectly contact the first hook section. The holding portion of the baby cradle can directly contact the covering element. Here, the covering element can ensure the damping and / or orientation fixation of the holding portion of the baby cradle, while the first hook section can ensure mechanical stability. In addition, the holding device of the covering element can be individually matched to the baby cradle (for example, matched to the spring). Therefore, when replacing the spring, it is also possible to simply match by replacing the covering element without having to replace the entire hook system. In addition, the holding device of the covering element can fix the holding portion of the baby cradle in a specific position (for example, in the middle position of the first hook section). Preferably, the holding device of the covering element can fix the holding portion of the baby cradle in three directions, so that the holding portion of the baby cradle can only be removed from the holding device of the covering element in one direction. This provides a particularly safe holding of the baby cradle.
[0026] Preferably, the covering element can be releasably fixed at the first holding area. The covering element can be designed so that the covering element can be introduced into the first holding area through the first introduction area. In the first holding area, the covering element can be held, for example, by at least partially surrounding the circumference of the first hook section. In addition, the covering element can have a through hole, which coincides with the through hole of the hook system when the covering element is fixed at the first holding area. Therefore, even if the covering element is provided, additional fastening elements can be provided at the hook system (for example at the first hook section). In addition, the covering element can have a gripping section, by means of which the covering element can be simply released from the first hook section. Therefore, it is ensured that the covering element can be released from the first hook section without damage and reversibly.
[0027] According to another aspect of the present invention, a spring cradle system for an infant or young child is provided, the spring cradle system comprising an elastic element, to which the baby cradle is fixed or can be fixed by means of a first retaining portion. The spring cradle system may comprise a retaining element having a second retaining portion. The spring cradle system may comprise a baby cradle hook system according to one of the above design schemes, wherein the hook system connects the retaining element to the elastic element or forms an engagement with the elastic element or can form an engagement. The elastic element may be, for example, a spring. Preferably, the spring cradle system has five elastic elements, which are respectively fixed at the retaining element by means of the baby cradle hook system. The elastic element may have a baby cradle at the side opposite to the first retaining portion, into which the infant or young child may be placed. In addition, the spring cradle system may have a drive unit, which is connected to the baby cradle. The connection may be achieved by a traction element. By driving the traction element, the baby cradle may be placed in a swing.
[0028] Preferably, the second holding portion of the holding element comprises a through hole with a configuration that is at least partially rectangular. In other words, the holding portion can have a through hole into which the second hooking section can be introduced. The through hole can have a shape that is elongated in the direction of gravity (in the operating position of the spring cradle system). In other words, the through hole can be longer in the direction of gravity than perpendicularly to the direction of gravity. As a result, the hooking system can be reliably held without the hooking system twisting. In addition, the holding element can have a thickness that substantially corresponds to the clear width of the second introduction area. It can be ensured that the holding portion of the holding element does not twist relative to the hooking system in the engagement area. It is thus ensured that the holding portion of the holding element can only pass through the introduction area in the second orientation. The spacing between the through hole and the edge of the holding element can define a first dimension of the holding portion. The first dimension of the holding portion can substantially correspond to the clear width of the rotation area. In other words, the holding portion of the holding element can be arranged in the rotation area in the second orientation. However, in order to reach the holding area of the second hooking section, the orientation of the holding portion relative to the second hooking section must be changed. The clear width of the second holding area can substantially correspond to the thickness of the holding element. Thus, by rotating the holding element by 90° relative to the hook section, the holding portion of the holding element reaches the second holding area of the second hook section. As long as the holding portion is accommodated in the holding area, the first length of the holding element now prevents the holding element from twisting relative to the hook section.
[0029] According to another aspect of the present invention, there is provided a use of the baby cradle hook system according to one of the above designs in a spring cradle system for infants or young children for connecting a retaining element with an elastic element.

[0043] Figure 1 A three-dimensional schematic view of a hook system 1 of a baby cradle according to one embodiment of the present invention is shown. The hook system 1 comprises a first hook section 3 and a second hook section 4. The first hook section 3 has a first holding area 31 and a first introduction area 32. The second hook section 4 has a second holding area 41 and a second introduction area 42. The first introduction area 32 and the second introduction area 42 are separated from each other by a tab 5. The first hook section 3 and the second hook section 4 are each formed by a substantially rectangular rod. The second hook section 4 also has a rotation area 43. The hook system 1 extends mainly along a main direction H. The hook system 1 is designed to hold the holding portion (in the middle) of the baby cradle 11 by means of the first hook section 3. Figure 1 Furthermore, the hook system is designed to hold the holding portion 6 of the holding element 2 (in Figure 1 ). Thus, the hook system 1 can fix the baby cradle on the holding element.
[0044] Figure 2 Show Figure 1Schematic top view of the hook system 1 in FIG. The second hook section 4 has a rotation region 43. The rotation region 43 has a clear width in the introduction direction R1, which is greater than the clear width of the holding region 41 in the introduction direction R1. The introduction region 42 has a clear width in the main direction H, which substantially corresponds to the clear width of the holding region 41 in the introduction direction R1. The first introduction region 32 has a larger clear width in the main direction H than the second introduction region 42.
[0045] Figure 3 1 shows a schematic perspective view of a hook system 1 which engages with a retaining element 2. More precisely, the second hook section 4 surrounds the retaining portion 6 of the retaining element 2. The retaining portion 6 of the retaining element 2 is Figure 3 , i.e. the end position, has its maximum extension in the main direction H. As a result, the retaining portion 6 of the retaining element 2 can be retained in the retaining region 41 of the second hook section 4, so that a relative twisting of the hook system 1 relative to the retaining element 2 is not possible. In other words, in Figure 3 The configuration shown in has a first orientation of the hook system relative to the retaining element. In this orientation, it is not possible to release the hook system 1 from the retaining portion 6 of the retaining element 2.
[0046] Figure 4 A schematic perspective view of the hook system 1 together with the holding element 2 is shown. More precisely, Figure 4 , the configuration corresponding to the second orientation is shown in . More precisely, the retaining portion 6 of the retaining element 2 can be introduced into the tilting region 43 of the second hook section 4 in the second orientation precisely via the introduction region 42. Due to the design of the retaining region 41 of the second hook section 4, however, it is not possible to introduce the retaining portion 6 of the retaining element 2 (in the second orientation) into the retaining region 41. For this purpose, the hook system 1 must be twisted relative to the retaining element 2 so that the narrow side of the retaining portion 6 of the retaining element 2 points in the main direction H. Subsequently, the retaining portion 6 of the retaining element 2 can be introduced into the retaining region 41 of the second hook section 4. The rotation region 43 is designed to allow such a relative movement between the hook system 1 and the retaining element 2. In other words, the rotation region 43 is the only region in the second hook section 4 in which a first orientation as well as a second orientation of the retaining element relative to the hook system 1 is possible.
[0047] Figure 5AA schematic view of a covering element 7 according to one embodiment of the invention is shown. The covering element 7 is a separate element and is made of a different material than the first hook section 3 and the second hook section 4.
