Abstract
Description
[0001] The invention relates to a frame, in particular an LED light box frame, comprising: a first frame element, at least one base element for setting up on a surface and a connecting arrangement which is designed to detachably connect the first frame element to the foot element, wherein in a foot connection state of the connecting arrangement the first frame element is connected to the foot element.
[0002] The use of LED light boxes for exhibitions and advertising purposes is known in the art. In one known design, a flat advertising medium, such as a printed fabric, is attached to a frame in a stretched state. To enable the frame to be placed on a surface, base elements are known that are integrally formed with the frame or detachably connected to the frame. In particular, the base elements can be attached to the frame vertically.
[0003] The disadvantage is that foot elements that are formed in one piece with the frame cannot be removed for transport, foot elements that can be screwed to the frame have to be assembled and disassembled in a time-consuming manner and known attachable foot elements do not offer sufficient support for large or heavy frames.
[0004] The object of the invention is therefore to alleviate or eliminate at least some of the disadvantages of the prior art. The invention specifically aims to create a frame of the type mentioned above that can be connected to foot elements quickly, easily, and reliably. In particular, the aim is to prevent the foot elements from becoming accidentally detached from the frame. Furthermore, the invention aims to provide a method of the type mentioned above with which the frame can be connected to foot elements quickly, easily, and reliably.
[0005] This object is achieved by a frame having the features of claim 1 and by a method as described below. Preferred embodiments and further developments are specified in the dependent claims.
[0006] According to the invention, the frame is characterized in that the connecting arrangement has a locking arrangement with a first locking part on the first frame element, a second locking part on the foot element and an operating element which is designed to be adjustable between a locking position in which separation of the first frame element from the foot element is blocked and a release position in which separation of the first frame element from the foot element is released, wherein in the foot connection state of the connecting arrangement, with the operating element in the locking position, the first locking part is locked to the second locking part and in the foot connection state of the connecting arrangement, with the operating element in the release position, the first locking part is released from the second locking part.
[0007] The frame is preferably composed of several frame elements and thus has a first frame element. The frame is preferably self-contained in its circumferential direction, thereby enclosing an interior space of the frame, and can have the shape of a quadrilateral, in particular a rectangle or square. A frame element is understood to be a visible circumferential section of the frame, wherein the first frame element or several frame elements, which have at least a first frame element, together form the frame. The frame elements can be straight or curved. In the case of a polygonal frame, each side edge of the frame can be composed of one, two or more than two frame elements. In particular, the frame can have several first frame elements which abut one another. The frame also has at least one foot element, which is intended for setting up on a surface.The foot element is designed to hold the frame in the intended position.
[0008] The frame further comprises a connecting arrangement configured to detachably connect the first frame element to the foot element. In a foot-connected state of the connecting arrangement, the first frame element is connected to the foot element via the connecting arrangement.
[0009] To prevent accidental release of the connection between the first frame element and the base element, the connecting arrangement has a locking arrangement with a first locking part on the first frame element, a second locking part on the base element, and an operating element. The operating element is different from the first locking part and the second locking part and can be actuated by an operator. Preferably, the first locking part and the second locking part are not visible when the first frame element and the base element are assembled and are accommodated, in particular, hidden in an interior region of the connecting arrangement, whereby the frame conveys a high-quality impression. The operating element, on the other hand, is visible and easily accessible for an operator.
[0010] The operating element is designed to be adjustable between a locking position, in which separation of the first frame element from the base element is blocked, and a release position, in which separation of the first frame element from the base element is released. In the base connection state of the connection arrangement, with the operating element in the locking position, the first locking part is locked to the second locking part. In the base connection state of the connection arrangement, with the operating element in the release position, the first locking part is released from the second locking part. It should be noted that the base connection state of the connection arrangement does not necessarily require the first locking part to be locked to the second locking part. In the release position, the first frame element can thus be manually separated from the base element by applying a separating force, wherein the locking arrangement preferably does not increase the separating force.Before separation, the first frame element and the base element were in the base-connected state of the connection arrangement. In the locking position of the operating element, however, the first frame element cannot be separated from the connected base element by applying the separation force, and in particular, cannot be separated non-destructively.
[0011] The first frame element and the foot element can therefore be quickly and easily connected to one another in correct mutual alignment by the connecting arrangement and can be locked together or released from the locking arrangement by the locking arrangement of the connecting arrangement.
[0012] When reference is made in the course of the description to location and direction specifications such as "top", "bottom", "front", "rear", "side", "longitudinal direction", "width direction" or "height direction", these specifications refer to the intended use of the frame, in which it is positioned on a surface. The term "vertical" means in the direction of gravity, from "top" to "bottom", or vice versa. If the frame is to be used in a different position, the location and direction specifications must be transferred accordingly. The longitudinal direction or the longitudinal extension of the frame element runs at least partially in the circumferential direction of the frame.
[0013] According to a preferred embodiment of the invention, the connecting arrangement can have a first connecting part on the first frame element and a second connecting part on the base element, wherein the first connecting part has the first locking part and the operating element, which is connected to the first locking part, and the second connecting part has the second locking part. The first connecting part and the second connecting part are designed to arrange the first frame element and the base element stably and in the intended position relative to one another when connected. Furthermore, since the first connecting part has the first locking part and the operating element and the second connecting part has the second locking part, the connecting arrangement can be designed to be particularly space-saving.Since the locking parts do not need to be mounted separately from the connecting parts on the first frame element and the base element, the first frame element can also be quickly joined to the base element. Since the control element is connected to the first locking part, the locking arrangement can be operated via the control element.
[0014] For a particularly stable connection of the first frame element to the base element, it is preferred that the first frame element has an inner side facing at least one other frame element of the frame and an outer side opposite the inner side, the first connecting part is fastened to the outer side of the first frame element, in particular is screwed to the outer side, and the second connecting part is fastened to the base element, in particular is screwed to the base element. Thus, in the base connection state, the first connecting part can rest on the second connecting part and the connecting arrangement can reliably absorb the weight of the frame in the vertical direction. In addition, an attractive appearance and a space-saving arrangement of the connecting arrangement can be achieved in this way.
[0015] To achieve a large-area connection arrangement with a small vertical extension, it can be provided that the second connecting part protrudes from the base element and has a connecting plate, and the first connecting part protrudes from the first frame element and has a receiving plate with a receiving groove in which the connecting plate is received in the foot-connected state. The connecting plate and the receiving plate can be designed with a large surface area and therefore prevent tilting of the first frame element on the base element more reliably than a small-area connection arrangement with a greater vertical extension, which is not provided for. In addition, the connecting plate and the receiving plate can be manufactured cost-effectively. In particular, the receiving plate has a larger surface area than the connecting plate received therein.Preferably, the height of the connecting plate running in the direction from the foot element to the first frame element corresponds to the height of the receiving groove, so that in the foot connection state the foot element also rests against the receiving plate in the entire area of the receiving plate surrounding the receiving groove.
[0016] For a particularly reliable design, it can be provided that the receiving groove has a receiving base and a front opening formed in a front side of the receiving plate for inserting the connecting plate and is delimited by two receiving side walls protruding from the receiving base, which run at an acute angle to one another from the front opening in the direction of a rear side of the receiving plate opposite the front side and have an undercut towards the receiving base, and the connecting plate has two connecting side walls which run at an acute angle to one another in the direction from the front opening to the rear side of the receiving plate and engage in the undercut. In the foot connection state, the connecting plate preferably rests against the receiving base and is held in position by the receiving side walls.The acute angle between the receiving side walls makes it easier to insert the connecting plate into the receiving groove. Due to the undercut of the receiving side walls, the distance between the receiving side walls increases towards the receiving base. Likewise, when viewing the connecting plate in the receiving groove, the distance between the connecting side walls increases towards the receiving base. The undercut thus prevents the connecting plate from becoming loose from the receiving groove in a direction perpendicular to the receiving base. It should be noted that the front side of the receiving plate and the front opening formed therein do not necessarily have to be the front side of the first frame element. Instead, depending on the orientation of the receiving plate, the connecting plate can be inserted into the receiving groove in a direction from a frame front to a frame rear or vice versa.
[0017] The locking arrangement can be particularly advantageously designed in that the first locking part connected to the operating element has a locking body which, in the locking position, projects into the receiving groove, and the second locking part is a locking notch in the connecting plate, into which locking notch the locking body engages in the base connection state, with the operating element in the locking position. Because the locking body projects into the receiving groove without actuation of the operating element, i.e., in the locking position of the operating element, and therefore engages in the locking notch in the base connection state of the connecting arrangement, the connecting plate is reliably held in the receiving groove and unintentional detachment of the first frame element from the base element is prevented.To intentionally release the first frame element from the base element, the operating element can be actuated, moving the operating element into the release position, which also changes the position of the first locking part and disengages the locking body from the locking notch. The locking body is preferably designed as a pin or leg. In particular, the locking body can be rigidly connected to the operating element via a transfer plate. The locking body and the operating element can preferably be arranged perpendicular to the transfer plate.
[0018] If the operating element is connected to the first locking part and is preloaded into the locking position by an elastic body, in particular a spring body, preferably resting on the first locking part, the operating element can be reliably held in the locking position without actuation by an operator. The elastic body can be a helical spring, for example. Alternatively, the elastic body can rest on the operating element. However, since the operating element is accessible to an operator and thus an elastic body resting on the operating element would also be accessible and therefore exposed to contamination and damage, the elastic body preferably rests on the first locking part and is in particular covered by the connecting arrangement.
[0019] For easy operation of the control element, the control element may be provided with an operating handle. The operating handle is preferably arranged on the outer side of the first frame element facing the ground.
[0020] The frame can be installed particularly stably on the ground if a longitudinal direction of the foot element is arranged at an angle, in particular perpendicular, to a longitudinal direction of the first frame element. Generally, the longitudinal direction of the foot element can be arranged at an angle in the range of 45° to 90° to the longitudinal direction of the first frame element. The longitudinal direction of the foot element refers to a main extension of the foot element.
[0021] To prevent the first frame element from accidentally detaching from the base element, the operating element can be designed to be adjustable in the longitudinal direction of the frame. Thus, if force is applied to the operating element perpendicular to the longitudinal direction of the frame element, the operating element cannot be moved from the locking position to the release position.
[0022] According to a further embodiment, the first connecting part and the second connecting part can be designed as flat bodies whose height dimensions in a height direction extending from an inner side to an outer side of the first frame element amount to at most 25%, preferably at most 20%, particularly preferably at most 15% of the distance between the inner side and the outer side of the first frame element. Thus, the connecting arrangement can be designed to save material, save space, and be cost-effective.
[0023] For a stable design of the connecting arrangement, it is preferred that the maximum dimension of the connecting plate in a foot width direction of the foot element be between 40% and 90%, preferably between 50% and 80%, of the dimensions of the foot element in the foot width direction. Thus, the connecting arrangement can reliably transfer forces acting on the first frame element to the foot element without damage. The foot width direction runs in a main plane of the foot element, perpendicular to the main extension of the foot element.
[0024] For a stable design of the connecting arrangement, it is further preferred that a dimension of the first connecting part in a frame width direction of the first frame element be at least as large as a dimension of the first frame element in the frame width direction. This allows the connecting arrangement to reliably transmit forces acting on the first frame element to the base element without damage. The frame width direction runs perpendicular to a frame plane spanned by the frame and perpendicular to the frame element longitudinal direction.
[0025] To achieve an attractive appearance, it is advantageous if the first frame element has a visible surface between an inner side facing at least one other frame element of the frame and an outer side opposite the inner side, in which surface illuminating elements, in particular light-emitting diodes, are accommodated. Preferably, the illuminating elements are covered with a translucent cover. Thus, at least a peripheral portion of the frame can be illuminated by the illuminating elements. The translucent cover can prevent accidental damage to the illuminating elements and is preferably removably mounted on the first frame element.
[0026] For an arrangement of advertising spaces of different shapes within the frame, it can be provided that an advertising medium surrounded by the frame is mounted on the first frame element, in particular, that it is rotatably mounted about a rotation axis extending in a frame plane defined by the frame, and that the advertising medium is spaced from the frame at least in sections. Thus, the advertising space can be arranged on at least one advertising medium within the frame.
[0027] According to the invention, the method mentioned at the outset comprises at least the following steps: - Providing the first frame element, the foot element and a connecting arrangement which is designed to releasably connect the first frame element to the foot element and has a locking arrangement with a first locking part on the first frame element, a second locking part on the foot element and an operating element; - To connect the first frame element to the foot element, moving the first frame element with respect to the foot element so that the connecting arrangement connects the first frame element to the foot element and the first locking part is locked to the second locking part; and - To release the first frame element from the foot element, actuating the operating element to transfer the operating element from a locking position in which separation of the first frame element from the foot element is blocked, to a release position in which separation of the first frame element from the foot element is released, whereby the first locking part is released from the second locking part, and separating the first frame element from the foot element.
[0028] The method thus serves to detachably connect a first frame element to a base element of a frame, in particular an LED light box frame. To connect the first frame element to the base element, the first frame element, the base element, and the connecting arrangement are provided. The connecting arrangement can be mounted on the first frame element and the base element even before the first frame element and the base element are provided. The connecting arrangement is designed to detachably connect the first frame element to the base element. The connecting arrangement also has a latching arrangement with a first latching part on the first frame element, a second latching part on the base element, and an operating element.
[0029] To connect the first frame element to the base element, these are moved towards each other and engaged with each other in such a way that the connecting arrangement connects the first frame element to the base element and the first locking part is locked to the second locking part.
[0030] To release the first frame element from the base element, the operating element is preferably operated manually, moving it from the locking position to the release position. Operating the operating element releases the first locking part from the second locking part. The first frame element is then separated from the base element.
[0031] With regard to the features of the method and the advantages achievable by the method, reference is also made to the preceding description of the framework, insofar as this description is helpful for understanding the method and insofar as features and advantages of the method can be derived from the description of the framework. Likewise, with regard to the features and advantages of the framework, reference is also made to the description of the method.
[0032] According to a preferred embodiment of the method, before connecting the first frame element to the foot element, a first connecting part of the connecting arrangement can be fastened to the outside of the first frame element, in particular screwed to the outside, and a second connecting part of the connecting arrangement can be fastened to the foot element, in particular screwed to the foot element.
[0033] The second connecting part can protrude from the foot element and have a connecting plate and the first connecting part can protrude from the first frame element and have a receiving plate with a receiving groove, wherein the connecting plate is received in the receiving groove for the transition to the foot connection state.
[0034] Preferably, in order to lock the first locking part with the second locking part, a locking body of the first locking part, which in the locking position projects into the receiving groove, is brought into engagement with a locking notch in the connecting plate in the foot connection state.
[0035] Preferably, the operating element is pre-tensioned into the locking position via an elastic body, in particular a spring body.
[0036] Preferably, the control element is adjusted between the locking position and the release position by operating an operating handle.
[0037] Preferably, a foot longitudinal direction of the foot element is arranged obliquely, in particular perpendicularly, to a frame longitudinal direction of the first frame element.
[0038] Preferably, the control element is adjusted in the longitudinal direction of the frame.
[0039] Preferably, luminous elements, in particular light-emitting diodes, which are accommodated in a visible surface arranged between an inner side and an outer side of the first frame element, are activated and preferably covered with a translucent cover.
[0040] Preferably, an advertising medium surrounded by the frame is mounted on the first frame element, in particular mounted so as to be rotatable about an axis of rotation, which axis of rotation runs in a frame plane spanned by the frame, wherein the advertising medium is mounted at least partially at a distance from the frame.

[0042] It should be noted that the Fig. 1 to 30 are not necessarily drawn to scale. Furthermore, for the sake of clarity, not all components of the frame are shown in all figures. In particular, different components may be omitted in different figures that depict the same sections of the frame.
[0043] Fig. 1 shows a frame 1, which can in particular be an LED light box frame composed of several frame elements 2. The frame 1 can serve as a support or as a border for advertising spaces. The frame 1 can have four side walls 3, namely an upper side wall 3a, a lower side wall 3b, and two lateral side walls 3c, as in the example shown. The upper side wall 3a and the lower side wall 3b can each be composed of three frame elements 2, while the two lateral side walls 3c can each be composed of two frame elements 2. The frame 1 is in Fig. 1 is designed to be self-contained in its circumferential direction UR and thereby encloses an interior space I of the frame 1. The interior space I is delimited by an inner side 4 of the frame 1, while an outer side 5 of the frame 1 opposite the inner side 4 can partially face a base U on which the frame 1 can be set up. The frame 1 has in particular a front side VS and a rear side RS, wherein at least the front side VS is designed to face a viewer. Each frame element 2 has a frame element longitudinal direction L running along part of the frame circumference, in the circumferential direction UR, a height direction H running from the inner side 4 to the outer side 5 and a frame width direction B running from the front side VS to the rear side RS.
[0044] The frame 1 comprises a first frame element 2a, a second frame element 2b and a Fig. 4 to 12 clearly visible connecting device 6. Preferably, each frame element 2 is a first frame element 2a or a second frame element 2b. The connecting device 6 is designed to detachably connect the first frame element 2a to the second frame element 2b. In Fig. 1, Fig. 3, Fig. 8, Fig. 9, Fig. 12 and Fig. In the connection state of the connecting device 6 shown in Figure 13, the first frame element 2a rests against the second frame element 2b, while in Fig. 4 and Fig. 10, the first frame element 2a is spaced apart from the second frame element 2b. The connecting device 6 has a locking device 7 with a first locking element 8 on the first frame element 2a, a second locking element 9 on the second frame element 2b and a release element 10, see Fig. 4 and Fig. 5. The trigger element 10 is between a Fig. 4, in which separation of the first frame element 2a from the second frame element 2b is blocked, and a release position (not shown), in which separation of the first frame element 2a from the second frame element 2b is released. In the connected state of the connecting device 6, with the release element 10 in the rest position, the first locking element 8 is locked to the second locking element 9. In the connected state of the connecting device 6, with the release element 10 in the release position, the first locking element 8 is released from the second locking element 9. Thus, the locking between the first locking element 8 and the second locking element 9 can be released by the release element 10.
[0045] It should be noted that in a frame 1 composed of first frame elements 2a and second frame elements 2b, each of the frame elements 2 preferably has a connecting device 6 on its two end faces 33 for connection to an adjacent first frame element 2a or second frame element 2b. Thus, for example, the first frame element 2a has Fig. 4 shown left end face 33 the first locking element 8 and at its in Fig. 4 not shown right end face 33, the second locking element 9. For the purpose of describing the connecting device 6, however, the frame element 2 in which Fig. 4 the first locking element 8 is designated as the first frame element 2a and that frame element 2 in which in Fig. 4, the second locking element 9 is designated as the second frame element 2b. Alternatively, for example, the first frame element 2a has Fig. 4 shown left end face 33 a first locking element 8 and also on its in Fig. 4 has a first locking element 8 on the right end face 33 not shown, while the second frame element 2b has a second locking element 9 on both end faces 33.
[0046] In the Fig. In Figures 4 to 7, the locking device 7 is not shown in the locked state, so that the first frame element 2a is spaced apart from the second frame element 2b, in particular, the opposing end faces 33 are spaced apart from each other. The trigger element 10 is in the rest position. Thus, the second locking element 9 is also in a position in which the second locking element 9 would engage the first locking element 8 if the first frame element 2a were connected to the second frame element 2b.
[0047] In the Fig. 8 and Fig. 9, the connecting device 6 is in the connected state and the trigger element 10 is in the rest position, so that without actuating the trigger element 10, ie without transferring the trigger element 10 into the trigger position, the first frame element 2a cannot be separated from the second frame element 2b.
[0048] The connecting device 6 has in the Fig. 4 to 12, a first connecting element 11 and a second connecting element 12. The first connecting element 11 is fastened to the first frame element 2a, and the second connecting element 12 is fastened to the second frame element 2b. In addition, the first connecting element 11 has the first locking element 8, and the second connecting element 12 has the second locking element 9 and the trigger element 10, which is connected to the second locking element 9. Because the trigger element 10, which is intended for actuation by a user, is connected to the second locking element 9, the locking connection between the first locking element 8 and the second locking element 9 can be released if necessary.
[0049] The Fig. 4 and 10 to 12 show, by way of example, that the inner side 4 of the first frame element 2a and the inner side 4 of the second frame element 2b have recesses 13 into which the first connecting element 11 and the second connecting element 12 are countersunk. In particular, the first connecting element 11 and the second connecting element 12 are received flush with the inner side 4, ie, the first connecting element 11 and the second connecting element 12 do not protrude beyond the inner side 4 in the direction of the interior space I.
[0050] In an embodiment not shown, the connecting device 6 can be provided partially on the outer side 5 of the frame 1. In this case, the outer side 5 of the first frame element 2a and the outer side 5 of the second frame element 2b can have the recesses 13 into which the first connecting element 11 and the second connecting element 12 are countersunk and preferably received flush with the outer side 5.
[0051] In the Fig. 4 and 10 to 12, the recesses 13 have a guide groove 14 into which a first fastening part 15 of the first connecting element 11 and a second fastening part 16 of the second connecting element 12 are inserted. In the example shown, the first fastening part 15 and the second fastening part 16 have through-openings 17 into which screws (not shown) can be inserted in order to screw the first fastening part 15 to the first frame element 2a and the second fastening part 16 to the second frame element 2b. The guide grooves 14 preferably have an undercut 18 into which a step 19 on the first connecting element 11, and possibly also on the second connecting element 12, engages. The guide grooves 14 preferably extend in the longitudinal direction L of the respective frame element 2.
[0052] The Fig. 4 to 12 further show, by way of example, that the first connecting element 11 has a connecting projection 20 protruding from the first frame element 2a, and the second connecting element 12 has a connecting recess 21 in which the connecting projection 20 is received in the connected state, preferably with a precise fit. The connecting recess 21 has an insertion opening 22 for inserting the connecting projection 20, an end wall 23 opposite the insertion opening 22, a base 24 extending between the insertion opening 22 and the end wall 23, and two recess side walls 25 protruding from the base 24, which extend at an acute angle to one another in the direction from the insertion opening 22 to the end wall 23 and have an undercut 26 toward the base 24.The connecting projection 20 preferably has two projection side walls 27 extending at an acute angle to each other in the direction of the end wall 23, which engage in the undercut 26 in the connected state. In the connected state, the projection side walls 27 preferably bear at least partially, in particular completely, against the recess side walls 25. The acute angle between the projection side walls 27 facilitates the insertion of the connecting projection 20 into the connecting recess 21.
[0053] In the example according to Fig. 5 clearly shows that the second locking element 9 is connected to the trigger element 10 and has a locking projection 28. In the rest position, the locking projection 28 projects into the connecting recess 21. The first locking element 8 is preferably a locking recess 29 in the connecting projection 20, into which the locking projection 28 engages in the connected state when the trigger element 10 is in the rest position. The locking projection 28 is preferably designed as a pin or leg. In particular, the locking projection 28 can be arranged at an acute angle to the frame element longitudinal direction L so that the locking projection 28 is adjusted by the projection side wall 27 touching the locking projection 28 when the connecting projection 20 is inserted into the connecting recess 21, and as a result the trigger element 10 is also adjusted from the rest position to the trigger position.In the example shown, the locking projection 28 is rigidly connected to the trigger element 10 via a guide plate 30, wherein the locking projection 28 and the trigger element 10 are arranged perpendicular to the guide plate 30.
