Disclosure of the invention

[0002] The invention is based on a holding device for releasably holding a rechargeable battery, in particular a bicycle rechargeable battery, on a frame, in particular on a bicycle frame, with at least one carrier unit which has at least one carrier element, in particular a guide rail, for at least partially receiving and / or guiding the rechargeable battery. The object of the invention is to provide a holding device with a compact carrier device. It is proposed that the holding device has at least one variation unit, arranged at least partially on the carrier element, for a variable arrangement of a locking unit, in particular viewed along a longitudinal axis of the carrier element, at different positions of the carrier element. The design of the holding device according to the invention advantageously makes it possible to achieve a high degree of flexibility when mounting a rechargeable battery on the holding device.In particular, a convenient radial and / or axial assembly and / or disassembly of an accumulator can be advantageously realized.

[0003] Preferably, the holding device is designed as a bicycle battery holder. In particular, the holding device is intended to enable at least temporary positioning of a battery in and / or on a bicycle. Specifically, the battery can be easily mounted in or removed from the holding device, preferably without tools. The holding device is specifically designed to be fixed to a bicycle frame, preferably within a bicycle frame, for example, in a top tube, seat tube, head tube, or preferably a down tube of the bicycle frame. For fixing in or on a bicycle frame, the holding device includes, in particular, fastening elements, such as screws, plug-in fasteners, or locking elements.Alternatively or additionally, it is conceivable that the holding device, preferably the carrier unit or the carrier element, is at least partially formed in one piece with the bicycle frame or at least a part of the holding device, preferably the carrier unit or the carrier element, is connected in one piece with the bicycle frame, for example welded or glued.

[0004] Preferably, the variation unit is designed to fix the locking unit at different positions on the support element. Preferably, the variation unit fixes the locking unit to the support element in at least one direction. More preferably, the variation unit fixes the locking unit to the support element in a fixed position. Particularly preferably, the variation unit fixes the locking unit to the support element in a rotationally fixed and / or positionally fixed manner. In particular, the variation unit is designed to arrange locking units of different configurations on the support element. It is conceivable that the variation unit has several positions for an arrangement of the locking unit.The variation unit preferably comprises at least one element that is provided for a positive and / or non-positive connection with the locking unit and / or the support element in order to arrange at least the locking unit on the support element in a positionally variable manner. The element of the variation unit can be designed as a positive-locking recess, a clamping element, a latching element, or another element that appears appropriate to a person skilled in the art. The variation unit is preferably intended to interact with a positive-locking element, such as a latching element or the like, arranged fixedly or movably on the locking unit, in particular on a base body of the locking unit. The variation unit is preferably designed such that the locking unit and / or a stop unit of the holding device can be arranged at different positions on the support element.

[0005] In particular, the locking unit is designed to fix the accumulator to the support unit. It is conceivable that the locking unit is attached to the support element. It is also conceivable that the locking unit is permanently connected to the accumulator. Preferably, the locking unit fixes the accumulator to the support element in at least one direction. More preferably, the locking unit fixes the accumulator to the variation unit arranged on the support element in a fixed position. Particularly preferably, the locking unit fixes the accumulator to the support element in a rotationally fixed and / or positionally fixed manner.

[0006] The variation unit can be designed as a locking unit, a clamping unit, a screwing unit, a rail slide unit, or any other unit deemed suitable by a person skilled in the art, which is intended to position at least the locking unit variably on the support unit by means of a positive and / or force-fit connection. At least a part of the variation unit is preferably arranged on the support element, in particular formed integrally with the support element. It is also conceivable that the variation unit is at least partially arranged on the locking unit. In an embodiment of the variation unit as a rail slide unit, the variation unit preferably comprises at least one rail slide which is movably mounted on the support element along a longitudinal axis of the support element.Particularly preferably, the variation unit designed as a rail slide unit has at least one locking element arranged on the rail slide, which is subject to spring tension. For example, the locking element is designed as a pin or the like. It is also conceivable for the variation unit designed as a rail slide unit to have at least one screw element or clamping element arranged on the rail slide. In particular, the locking element arranged on the rail slide can engage in corresponding form-fitting elements, in particular locking recesses, of the variation unit in certain positions of the rail slide on the support element. In particular, the variation unit designed as a rail slide unit has an actuating unit which is provided for releasing the locking element from a locked state when the actuating unit is actuated.

[0007] Furthermore, it is proposed that the variation unit have at least two form-locking elements for a variable arrangement of the locking unit, in particular viewed along a longitudinal axis of the carrier element, at different positions of the carrier element. This advantageously makes it possible to realize a simple and space-saving holding device. The design according to the invention particularly advantageously ensures that the locking unit can be arranged in different positions. In particular, the form-locking elements of the variation unit are provided for an arrangement of the locking unit. In particular, the form-locking elements are provided to establish a form-lock connection with at least part of the locking unit in an operating state.In particular, the positive locking elements form positive locking recesses designed to receive a part of the locking unit, especially positive locking mating elements of the locking unit, for the purpose of creating a positive locking connection. Preferably, the positive locking elements are designed as recesses or depressions in the variation unit, particularly recesses or depressions arranged on the support element. Particularly preferably, the positive locking elements of the variation unit are designed as polygonal, especially rectangular, recesses. It is also conceivable that the positive locking elements of the variation unit are designed as elongated holes, as round, oval, elliptical, or as other recesses or depressions that would appear useful to a person skilled in the art. It is also conceivable that the positive locking elements of the variation unit are designed as recesses with different shapes.In particular, the form-locking elements can be arranged on any side, for example a right side, a left side, a top side or a bottom side, of the support element or the frame, as seen relative to a setting-up direction of the frame, in particular of the bicycle frame.

[0008] It is further proposed that the at least two form-locking elements are arranged at different distances from a stop unit of the holding device, which is arranged in particular at one end of the carrier element, along a longitudinal axis of the carrier element. This advantageously makes it possible to provide a holding device that allows the installation of batteries of different lengths. The design according to the invention particularly advantageously makes it possible to realize a space-saving holding device. In particular, the stop unit is provided to limit at least one axial movement of the battery relative to the carrier unit in an installation or insertion direction during installation and / or in an operating state. Preferably, the stop element is connected to the carrier unit, in particular to the carrier element of the carrier unit, in a force-fitting, form-fitting and / or material-fitting manner.In particular, the accumulator is clamped, especially clamped and / or snapped, between the locking unit and the stop unit in an operating state arranged on the support element. Preferably, the accumulator is clamped between the stop unit and the locking unit such that, in the clamped operating state, the locking unit exerts a compressive force on the accumulator, which acts in the direction of the stop unit, especially parallel to a longitudinal axis of the support element. Alternatively or additionally, it is conceivable that the holding device includes an adapter element, which is designed to be clamped between the stop element and the accumulator. Preferably, the adapter element is plated through to ensure an electrical connection between the accumulator and the stop element.

[0009] Furthermore, it is proposed that the holding device comprises the locking unit, in particular the previously mentioned one, which is variably arranged on the carrier unit by means of the variation unit. The locking unit is designed to detachably fasten the accumulator to the carrier unit. In particular, it is conceivable that the locking unit is attached to the variation unit of the carrier element and that the accumulator is clamped, in particular clamped and / or snapped, between the stop unit and the locking unit by radially sliding the accumulator. However, it is also conceivable that the locking unit is fixedly arranged on the accumulator and that the locking unit is arranged in one step on the variation unit to form a detachable holder for the accumulator on a frame, in particular a bicycle frame.

[0010] Furthermore, the holding device according to the invention comprises an accumulator, in particular the aforementioned one, wherein the accumulator has a locking unit for the releasable attachment of the accumulator to the variation unit arranged on the support element. This advantageously allows axial mounting and dismounting of the accumulator on the holding device. The holding device according to the invention particularly advantageously enables the releasable mounting of accumulators of different lengths. Preferably, the locking unit is arranged on one side of the accumulator, in particular on the side of the accumulator opposite the side of the accumulator facing the stop unit.Preferably, the locking unit comprises a clamping unit designed to fix the accumulator to the support unit in a clamped operating state and to clamp the accumulator between the locking unit and the stop unit in an operating position, in particular by clamping and / or snapping it into place, such that the clamping unit exerts a compressive force on the accumulator in the clamped operating state, acting in the direction of the stop unit, in particular parallel to a longitudinal axis of the support element. The term "clamped operating state" is understood to mean, in particular, a state of the holding device in which the clamping unit is clamped, in which the accumulator is fixed in the holding device, and / or in which the accumulator is in the operating position, i.e., in particular, in which energy output from the accumulator, for example to the auxiliary motor, is enabled.It is conceivable that the clamping unit has an operating element which, apart from a key for operating a lock, is designed to be operated without tools. This can advantageously enable particularly simple assembly, disassembly, or battery replacement. In particular, the clamping unit can be operated entirely by hand via the operating element. This can advantageously achieve a particularly high level of user-friendliness. An "operating element" is understood to mean, in particular, an element that has a control surface for an operator to adjust the operating state, especially the clamped and unclamped operating states, of the clamping unit.In particular, the operating element is designed as a lever, for example as a rocker switch, a pull lever, or a rotary lever, or as a button, for example as a push button or a push button. Particularly when the operating element is designed as a rocker switch, simple ergonomics can be advantageously achieved, especially since in this case the actuation direction of the rocker switch overlaps with the insertion direction of the accumulator into the holding device as defined by the support element. It is particularly conceivable that the clamping unit has a toggle lever, wherein the operating element preferably forms at least a part, in particular a leg, of the toggle lever. By using a toggle lever, a high clamping force can advantageously be achieved with manual operation while maintaining a substantially constant effort from the operator during the clamping process.In particular, an actuating force for actuating the operating element is at least substantially constant or linear, while the compressive force generated by a clamping element of the toggle lever, which in particular forms another leg of the toggle lever, increases or decreases exponentially. In addition, a toggle lever can advantageously ensure that the operating element is mounted at least substantially force-free in the clamped state, since in particular the compressive force acts on another leg of the toggle lever. This advantageously makes it possible to achieve a long service life of the clamping unit. Alternatively or in addition to a toggle lever, the clamping unit can have a rotary latch, a screw cap, a bayonet lock or the like as a clamping mechanism. In particular, the operating element simultaneously forms a handle element, which is provided at least to facilitate removal of the battery.In particular, the handle is designed as a pull tab. The pull tab can advantageously be grasped by the operator's hand and used to pull the accumulator out of the holding device. The clamping unit preferably includes a clamping element designed to support at least a large portion of the compressive force occurring in the clamped operating state against the support element or the frame. This advantageously ensures secure clamping of the accumulator. In particular, higher forces can be absorbed by the clamping unit when the distance between a point of application of the clamping force on the accumulator and a point of application of the clamping force on the support element is smaller than the distance perpendicular to the mean force direction. In particular, the clamping element forms at least a part, especially a leg, of the toggle lever, which is preferably different from the operating element.In particular, the clamping element is connected to the operating element via a joint. Alternatively, however, it is also conceivable for the clamping unit to have only a simple rocker lever without a toggle lever geometry. In this case, the operating element in particular can also be formed integrally with the clamping element. In particular, the clamping element is intended to engage with part of the support unit or with part of the frame during the clamping process in order to generate the compressive force. It is conceivable for the locking unit to be fastened to the support element using a clamping unit as described above, so that an accumulator pushed radially between the locking unit and the stop unit can be clamped between the locking unit and the stop unit, for example by means of latching elements or clamping elements arranged on the locking unit. It is also conceivable for the locking unit to be screwed to the support unit.

[0011] Furthermore, it is proposed that the support element has at least one side wall curved or angled relative to a principal extension plane of the support element, which at least partially covers the accumulator laterally in at least one state arranged on the support unit. It is conceivable that, in an alternative embodiment, the holding device for solving a problem according to the invention is designed independently of the variation unit.Preferably, in the alternative embodiment, particularly in the embodiment designed independently of the variation unit, the holding device comprises at least the support unit, which has at least one support element, in particular a guide rail, for at least partially receiving and / or guiding the accumulator. The support element has at least one side wall curved or angled relative to a principal extension plane of the support element, which at least partially covers the accumulator laterally in a state arranged on the support unit. This advantageously allows at least partial guidance of the accumulator. In particular, the accumulator is partially guided by the side walls, at least during assembly. In particular, the accumulator is at least partially supported by the side walls in an operating state. It is conceivable that the side wall has a sliding element.This advantageously prevents damage, such as scratching of the accumulator and / or the support element, to a large extent. It is also conceivable that the side wall has several sliding elements. For example, the sliding element can be designed as a sliding roller or as a sliding film. "Laterally covered" is understood to mean, in particular, that an axis perpendicular to an outer wall of the accumulator intersects both the side wall and the outer wall of the accumulator, wherein preferably the maximum extent of the side wall is smaller than the maximum extent of the outer wall of the accumulator, especially along a direction perpendicular to the longitudinal axis of the support element and parallel to the outer wall of the accumulator. Most preferably, the side wall is formed integrally with the support element.Preferably, the side wall is arranged on the support element such that a principal direction of extension of the side wall runs parallel to the longitudinal axis of the support element. It is conceivable that a maximum length of the side wall, particularly along its principal direction of extension, corresponds to the maximum length of the support element, particularly along its longitudinal axis. A "principal direction of extension" of a component is understood to be, in particular, a direction that runs parallel to a longest edge of the smallest geometric cuboid that just completely encloses the object. A "principal plane of extension" of a component is understood to be, in particular, a plane that is parallel to a largest face of the smallest possible imaginary cuboid that just completely encloses the component, and in particular, that passes through the center of the cuboid.Preferably, the side wall of the support element forms an angle with the main extension plane of the support element, particularly of less than 180°, more preferably of less than 120°, and most preferably of more than 90°. It is also conceivable that the side wall completely covers the accumulator laterally.

[0012] Furthermore, it is proposed that the support element has at least one side wall curved or angled relative to a main plane of extension of the support element and at least one further side wall curved or angled relative to the main plane of extension of the support element, wherein the variation unit is arranged at least in a region between the side wall and the further side wall. This advantageously allows for guidance of the accumulator on both sides, particularly during assembly and / or disassembly. Preferably, when arranged on the support element, the locking unit is guided at least partially through the side wall and / or the further side wall. In particular, the side wall and the further side wall can at least partially support the accumulator in an operating state. Specifically, the side walls can protect the accumulator against damage.It is conceivable that the locking unit is at least partially supported by the side wall and the additional side wall. This advantageously results in high stability of the holding device. It is conceivable that the additional side wall has a sliding element. This advantageously prevents damage, such as scratching of the accumulator and / or the support element, to a large extent. It is also conceivable that the additional side wall has several sliding elements. In particular, the additional side wall is formed integrally with the support element. Preferably, the additional side wall is arranged on the support element such that a principal direction of extension of the additional side wall runs parallel to the longitudinal axis of the support element.It is conceivable that the maximum length of the additional side wall, particularly along its principal extension direction, corresponds to the maximum length of the support element, particularly along its longitudinal axis. Preferably, the additional side wall of the support element forms an angle with the principal extension plane of the support element, particularly of less than 180°, more preferably of less than 120°, and most preferably of more than 90°. The side wall and the additional side wall are arranged such that their principal extension directions are parallel to each other. It is conceivable that the side wall and the additional side wall have identical dimensions. It is also conceivable that the side wall and the additional side wall have different dimensions.It is conceivable that the angles, in particular the magnitudes of the angles, at which the side wall and the further side wall are angled at least to the main extension plane of the support element, are identical. It is also conceivable that the angles, in particular the magnitudes of the angles, at which the side wall and the further side wall are angled at least to the main extension plane of the support element, are different. It is also conceivable that the further side wall completely covers the accumulator laterally.

[0013] Furthermore, it is proposed that the carrier element has at least one side wall, in particular the one already mentioned above, which is curved or angled to a main extension plane of the carrier element, in particular the one already mentioned above, and at least one further side wall, in particular the one already mentioned above, which is curved or angled to the main extension plane of the carrier element, wherein the variation unit is arranged at least partially on the side wall and / or on the further side wall. This can advantageously improve the holding strength of the holding device. It is conceivable for the side wall and / or the further side wall to have form-fitting elements. This can advantageously achieve a high level of stability of the holding device. The variability of the arrangement of the locking unit on the carrier element can advantageously be increased.It is conceivable for the side wall and / or the further side wall to have one or more form-locking elements of the variation unit. It is conceivable for the form-locking elements of the side wall and / or the further side wall to be provided for arranging the locking unit. In particular, the form-locking elements of the side wall and / or the further side wall can, in an operating state, establish a form-lock connection with at least part of the locking unit. Preferably, the form-locking elements of the side wall and / or the further side wall form form-locking recesses which are provided for accommodating part of the locking unit, in particular form-locking fitting elements of the locking unit, in order to establish a form-locking connection. The form-locking elements are preferably designed as recesses or as depressions in the side wall and / or the further side wall of the carrier element.Particularly preferably, the form-locking elements of the side wall and / or the further side wall are designed as polygonal, in particular rectangular, recesses. It is also conceivable for the form-locking elements of the side wall and / or the further side wall to be designed as elongated holes, as round, oval, elliptical, or as other recesses or depressions that appear appropriate to a person skilled in the art. It is also conceivable for the form-locking elements of the side wall and / or the further side wall to be designed as recesses with different shapes. It is conceivable for the variation unit to have one or more sliding elements.

[0014] Furthermore, a frame, in particular a bicycle frame, with at least one holding device according to the invention is proposed. Preferably, the frame has at least one elongated element; particularly advantageously, the frame is formed entirely of elongated elements. In this context, an "elongated element" is understood to be, in particular, an element in which the smallest possible imaginary cuboid that can just accommodate the element has a length that is at least five times, advantageously at least ten times, and particularly advantageously at least fifteen times the width and height of the cuboid. In particular, the frame can have at least one recess for receiving the holding device, in particular the support element, and the accumulator. The recess can, for example, be designed as a depression or a cavity in the frame.By at least partially arranging the holding device, in particular the support element, within a cavity of the frame, the appearance of the frame can be improved in the state where the accumulator is arranged on the support element, and / or the wall thickness of the frame can be reduced, and / or the penetration of contaminants and / or liquids into the accumulator can be prevented. Arranging the holding device and / or the support element within the cavity is particularly advantageous when the frame is designed as a lightweight frame, for example, a carbon frame.

[0015] It is also proposed that the frame comprise a tubular frame element which is intended to accommodate at least a large part of the holding device and at least a large part of a rechargeable battery held by the holding device within its interior. This advantageously enables particularly space-saving storage of the rechargeable battery. In addition, a storage option for particularly long rechargeable batteries, which therefore have a high energy storage capacity, can advantageously be created. A “large part” of a component should be understood to mean in particular at least 30%, preferably at least 50% and particularly preferably at least 70% of the total volume of the component. The rechargeable battery is preferably inserted into the frame element along its longitudinal axis. In particular, the support element extends parallel to the frame element.In particular, during assembly, the battery is guided along the support element until it hits the stop unit fixed to the support element. Alternatively, however, it is also conceivable for the battery to be inserted into the interior of the frame element through a lateral opening in the frame element. It is also conceivable for the battery to be mounted radially on the support element when inserted through a lateral opening in the frame element.

[0016] The holding device and / or the frame according to the invention are not intended to be limited to the application and embodiment described above. In particular, the holding device and / or the frame according to the invention can have a number of individual elements, components, and units that differs from the number stated herein to fulfill a functionality described herein.

The fitting elements 80a are intended to engage in corresponding recesses (not shown) of the battery 10a. This makes it possible to achieve an advantageous holding of the accumulator 10a and / or to largely prevent an unsuitable accumulator 10a from being pushed into the receiving area 78a and thus possibly damaging the plug element 44a.

[0023] Fig. 4 shows a schematic representation of the holding device 48a with the locking unit 106a arranged on the carrier unit 14a for radially mounting a battery 10a on the holding device 48a. The locking unit 106a is preferably arranged at a position on the carrier element 16a. In particular, the locking unit 106a is arranged at a position on the carrier element 16a by means of the variation unit 104a. The locking unit 106a preferably has form-locking elements corresponding to the form-locking elements 32a, 34a, which can engage in the form-locking elements 32a, 34a for fixing. It is conceivable that a clamping unit 20a analogous to the clamping unit 20b of the locking unit 106b is used to fix the locking unit 106a to the carrier element 16a.After the locking unit 106a has been arranged on the support element 16a, the accumulator 10a can be slid radially onto it and fixed to the support element 16a by the locking unit 106a. In particular, the accumulator 10a is fixed to the support element 16a by means of detent elements, clamping elements or other fastening elements that are obvious to a person skilled in the art and arranged on the locking unit 106a.

[0024] Fig. Figure 5 shows a side view of the holding device 48a with an alternative accumulator 10a'. The alternative accumulator 10a' is shorter than the accumulator 10a shown previously. Viewed along the longitudinal axis 24a, the alternative accumulator 10a' is shorter than the receiving area 78a. Furthermore, the Fig. 5 an alternative clamping unit 20a'. The alternative clamping unit 20a' is fixedly connected to the support element 16a. The alternative clamping unit 20a' is designed separately from the alternative accumulator 10a'. The holding device 48a has an adapter element 58a. The adapter element 58a is designed to fill a gap 102a formed between the stop unit 18a and the alternative accumulator 10a'. The adapter element 58a has a longitudinal extent corresponding to the longitudinal extent of the gap 102a. The adapter element 58a has at least one plug element 94a, 96a on each of two opposite sides. The first plug element 94a of the adapter element 58a is designed to connect to the plug element 44a of the stop unit 18a. The second plug element 96a of the adapter element 58a is intended for connection to a plug element 98a of the alternative accumulator 10a'.The plug elements 94a, 96a of the adapter element 58a are connected to each other by an electrical line 100a. The adapter element 58a is plated through.

[0025] In the Fig. Figures 6 to 10 show a further embodiment of the invention. The following descriptions and drawings are essentially limited to the differences between the embodiments, whereby, with regard to identically designated components, in particular components with the same reference numerals, reference is also generally made to the drawings and / or the description of the other embodiments, in particular the Fig. 1 to 5. To distinguish the embodiments, the letter a is added to the reference numerals of the embodiment in the Fig. 1 to 5. In the examples of the Fig. In paragraphs 6 to 10, the letter a is replaced by the letter b.

[0026] Fig. 6 shows a schematic representation of a holding device 48b with a locking unit 106b arranged on a battery 10b for axially mounting the battery 10b on the holding device 48b. The battery 10b has a clamping unit 20b, which is intended to arrange the locking unit 106b on a variation unit 104b arranged on a carrier element 16b of the carrier unit 14b. During axial mounting, the battery 10b is pushed onto the carrier element 16b along a longitudinal axis 24b and is guided at least partially by side walls 110b, 112b until the battery 10b encounters a stop unit 18b. The clamping unit 20b can be moved from a relaxed state to a clamped operating state 22b in this position to fix the accumulator 10b to the support element 16b.

[0027] Fig. Figure 7a shows another part of the holding device 48b in the tensioned operating state 22b with the accumulator 10b and the locking unit 106b. The locking unit 106b includes the clamping unit 20b. The clamping unit 20b is designed to fix the accumulator 10b to the support unit 14b in the tensioned operating state 22b. The clamping unit 20b is designed to clamp the accumulator 10b between the clamping unit 20b and the stop unit 18b in an operating position such that the clamping unit 20b exerts a compressive force on the accumulator 10b in the tensioned operating state 22b, which acts in the direction of the stop unit 18b. The compressive force exerted on the accumulator 10b by the clamping unit 20b in the tensioned operating state 22b acts parallel to the longitudinal axis 24b of the support element 16. A force in the Fig. The spring device 38b shown in Figure 6 generates a spring force in the tensioned operating state 22b that counteracts the tensioning force of the tensioning unit 20b. The tensioning unit 20b is fixedly connected to the accumulator 10b. The tensioning unit 20b is mounted on the accumulator 10b. The tensioning unit 20b has a housing 54b. The housing 54b closes off the tensioning unit 20b to the outside, at least on a side facing away from the accumulator 10b. The tensioning unit 20b has an operating element 26b. The operating element 26b is designed as a rocker lever. The operating element 26b is designed to be operated without tools. The tensioning unit 20b has a locking device 36b. The locking device 36b secures the operating element 26b in the tensioned operating state 22b. The locking device 36b has a further operating element 66b. The additional control element 66b is designed as a push button.The additional operating element 66b is designed, at least, to release the locking device 36b when actuated. In a closed state, i.e., in the tensioned operating state 22b, the operating element 26b is flush with a front face of the clamping unit 20b, in particular with the housing 54b of the clamping unit 20b. This advantageously prevents unwanted manipulation (e.g., theft). Furthermore, this provides an operator of the operating element 26b with a clear indication that the operating element 26b, and thus the accumulator 10b, is correctly secured.

[0028] Fig. Figure 7b shows a vertical section through the further part of the holding device 48b. Fig. 7a. The clamping unit 20b of the locking unit 106b has a clamping element 28b. The clamping unit 20b has a toggle lever 82b. The operating element 26b forms one leg of the toggle lever 82b. The clamping element 28b forms another leg of the toggle lever 82b. Pivoting the operating element 26b causes the clamping element 28b to pivot. In the clamped operating state 22b, the clamping element 28b is designed to support at least a large part of the compressive force on the support element 16b. Alternatively, in the clamped operating state 22b, the clamping element 28b can be designed to support the compressive force directly on the frame 12b. The clamping element 28b has a positive locking element 30b. The positive locking element 30b is claw-shaped. The clamping unit 20b is designed to maintain the compressive force in the clamped operating state 22b.The variation unit 104b of the support element 16b has corresponding positive locking elements 32b, 34b. The corresponding positive locking elements 32b, 34b are designed to engage with the clamping element 28b of the clamping unit 20b to establish the clamped operating state 22b. The corresponding positive locking elements 32b, 34b are formed as recesses in the support element 16b. In the clamped operating state 22b, the claw-like positive locking element 30b engages with a corresponding positive locking element 32b, 34b and locks into place. Due to the toggle lever geometry of the toggle lever 82b, the clamping unit 20b is pressed towards the accumulator 10b when the operating element 26b is closed. The variation unit 104b of the holding device 48b is analogous to the variation unit 104a. Fig. Three corresponding positive locking elements 32b, 34b are arranged. The different corresponding positive locking elements 32b, 34b are arranged at different distances from the stop unit 18b along the longitudinal axis 24b of the support element 16b. The different corresponding positive locking elements 32b, 34b serve to enable the assembly of accumulators 10b of different lengths.

[0029] The Fig. 8a and Fig. 8b show the part of the holding device 48b with the locking unit 106b in a relaxed operating state 84b. The operating element 26b is completely folded outwards. Due to the toggle lever geometry, the clamping element 28b is folded out of the corresponding form-locking element 32b, 34b of the variation unit 104b of the carrier unit 14b. The operating element 26b and the clamping element 28b are free from contact with the carrier unit 14b. The accumulator 10b with the locking unit 106b, which has the clamping unit 20b, can be removed from the receiving area 78b along the longitudinal axis 24b of the carrier element 16b in the relaxed operating state 84b. The operating element 26b forms a gripping element, in particular a pull tab, in the relaxed operating state 84b. For the sake of clarity, Fig. 7a and Fig. 7b Parts of the locking device 36 omitted.

[0030] The Fig. Figure 9 shows a horizontal section through part of the clamping unit 20b of the locking unit 106b with the locking device 36b. In the Fig. In the position shown in Figure 9, the operating element 26b is secured in the tensioned operating state 22b by the locking device 36b. The locking device 36b has a detent element 60b. The detent element 60b is designed as a detent hook. The locking device 36b has a locking element 62b. The locking element 62b is inserted into the operating element 26b. The locking element 62b has the further operating element 66b. The locking element 62b has a counterpart 86b. The counterpart 86b rests against the detent hook in the tensioned operating state 22b secured by the locking device 36b. The locking element 62b is engaged with the detent hook via the counterpart 86b.The locking of the counterpart 86b of the locking element 62b with the locking hook prevents movement of the operating element 26b connected to the locking element 62b, at least in one pivoting direction of the operating element 26b, in particular in a direction parallel to the longitudinal axis 24b of the support element 16b. The locking device 36b has a spring element 88b. The spring element 88b supports the locking element 62b relative to the operating element 26b. The locking element 62b is supported on the operating element 26b by the spring element 88b in the direction of an actuation direction 90b of the locking element 62b, in particular of the further operating element 66b. By pressing on the further operating element 66b, the spring element 88b is compressed and the counterpart 86b is disengaged from the locking element 60b.As a result, the spring mechanism 38b of the stop unit 18b pushes the accumulator 10b slightly out of the receiving area 78b. This causes the operating element 26b to pivot slightly, preventing the locking element 62b from re-engaging with the detent element 60b. The accumulator 10b is thus released and can be removed from the receiving area 78b along its longitudinal axis 24b. The locking element 62b has a positioning element 92b. The positioning element 92b is designed to prevent the locking element 62b from detaching from the operating element 26b. Furthermore, the positioning element 92b is designed to limit the maximum extension of the spring element 88b.

[0031] Fig. Figure 10 shows an exploded view of part of the clamping unit 20b. Individual parts of the in Fig. The clamping unit 20b shown in 10 differs from the previous ones. Fig. 6 to 9 exhibit slightly differing forms, but their functions are essentially identical. Components bearing the same designations or reference numerals in the following description and drawing correspond to the aforementioned components and have their functions. In addition to the design of the Fig. The holding device 48b shows 6 to 9 from the Fig. 10. A lock 40b is installed. The lock 40b is designed to lock and / or unlock the clamping unit 20b. The lock 40b is integrated into the housing 54b of the clamping unit 20b.
