Description

The invention relates to a holding device with the features of the preamble of claim 1.

The invention also relates to a folding poster stand with two holding devices.

Such a holding device for holding posters or other information carriers on a suitable rear wall is from the EP 2 682 932 A1 known. Such fixtures generally have legs to be placed as needed at a particular destination as opposed to fixed billboards. In addition, known holding devices are generally designed for rapid replacement of the posters held on the rear wall.

The AT 008 943 U1 discloses a poster display with at least one panel-like poster holder, which is provided with a provided for placing the posters back wall and legs. Along the edges of the rear wall retaining strips for holding the posters are arranged. The retaining strips each have a strip-shaped base part and a hingedly connected thereto, strip-shaped front part, which releases the rear wall for inserting and removing the posters in an open position, and presses the posters against the rear wall in a closed position with a border zone. The legs are in the form of a three-legged angle piece, wherein a first substantially vertical leg forms the lower portion of a support leg, and a second substantially horizontal leg is provided to be provided with a arranged at the bottom of the rear wall retaining strip. The third, arranged in extension of the first leg leg is designed as a connecting element and can be inserted into the retaining strip to be screwed or riveted to the retaining strip. In practice, considerable problems have occurred in the connection of retaining strip and pillar.

The DE 20 2010 009 779 U1 relates to a poster stand with one each preferably designed as a folding frame front part and rear part, which are connected to each other via hinges. For holding posters or other information carriers four frame flaps are provided per folding frame. The two snap frames are screwed along their long sides on square profiles, which also form the legs of the poster stand.

The DE 20 2010 010 684 U1 discloses a clamping frame formed from profiled strips in order to receive a groove of a stretchable surface material in grooves of the profile strips. The grooves receiving the piping are covered with frame flaps. The frame flaps are pivotally mounted on frame strips, which are bolted to the profile strips, riveted, glued or welded. In addition, legs are arranged in the lower part of the tenter frame.

The EP 0 895 214 A2 relates to a stand for posters, which has from the bottom to near the upper edge of the stand extending legs, which are connected to a base part of acting as terminal strips side edge strips.

The devices known from the prior art thus have at least one frame for fixing, in particular for clamping an information carrier and legs. The frames, which may be joined together along their longitudinal sides of a plurality of mutually parallel strips, are connected, for example by telescoping and / or screwing, with the legs. In addition to a resulting disadvantageous assembly effort for the connection of the individual components, a reliable, often exposed to strong mechanical loads connection of the legs with the frame generally only by massive, weight-increasing constructions or structures that ensure the largest possible connection area can be achieved.

In contrast, prior art small connection surfaces of the legs with the frame can result in the use of the devices to break the joints.

It is an object of the invention to provide a holding device and a folding poster stand with two holding devices as stated above, which avoid or at least reduce the disadvantages of the prior art. In particular, the holding device, with the lowest possible assembly costs for the connection of the holding device forming individual components, inexpensive and easy to manufacture. The legs are also designed to save weight and space and yet satisfying the high demands on mechanical strength.

This object is achieved by a holding device according to claim 1 and by a folding poster stand with two holding devices according to claim 13. Advantageous embodiments and further developments are specified in the dependent claims.

According to the invention, in the holding device, the two profiled strips each have an extension extending beyond a lower edge of the rear wall and integrally formed with the rest of the profiled strip. The extension can in particular stand legs of the holding device. The legs are thus not designed as separate, manufactured separately from the moldings, components that need only be connected to the assembly of the holding device in a separate step with the moldings or other arranged along the rear wall frame members. Instead, the legs are integrally formed with the profile strips as their extension. The production of the legs is thus particularly simple and inexpensive by the already produced profile strips are produced with greater length. In this way, no joints between the moldings and the legs are required, which could fail in the case of when using the fixture any high mechanical stress.

The one-piece design of the legs with the moldings is space and weight saving, since no additional, arranged on the moldings legs are required. However, the extensions of the profile strips can also be connected to a leg extension, and thus represent only a part of legs of the holding device. Overall, this results in a simple to manufacture and to assemble, stable construction of the holding device, and also because the so extended profiled strips are respectively connected along the longitudinal sides of the rear wall with this. In addition, a retaining strip is in each case pivotally mounted on the two profile strips, with which the information carrier or the poster held on the rear wall, in particular clamped, can be. Preferably, the retaining strips do not extend beyond the upper and lower edges of the rear wall.

When reference is made in this description to vertical longitudinal sides, a top or bottom edge of the rear wall or other positional or directional indications, these data are to be understood on the assumption that the holding device is arranged in its position of use.

In the present invention, at least a portion of a lower cross bar of a common holding frame formed with the receiving frame is formed integrally with at least one receiving channel as a delay element, wherein the receiving channel is formed for at least partially receiving the extension of the profile strip. The delay element is thus pushed, starting from the bottom side of the extension of the profile strip or the supporting leg with its receiving channel on at least a portion of the supporting leg, and at the same time forms at least a portion of the lower cross bar of the receiving frame for the rear wall. In this way, on the one hand a support for the rear wall is created and on the other hand, the legs or the extensions of the moldings, at least in the area covered by the push-pull, better protected against mechanical damage and contamination. In particular, the delay element prevents the area covered thereby the view of the profile of the moldings and thereby ensures an improved visual impression of the legs.

When the receiving channel or a bottom of the push-in extending on the extension of the profile strip state extending beyond the extension of the profile strip down, the delay element represents a leg extension. Thus, the extensions of the moldings together with and without the deferred push member, which optionally causes a leg extension, be considered as legs. The push-on element may also have a color as needed and, in order to increase the stability of the erected holding device, be provided with a non-slip floor covering. For a space-saving design of the delay element and for its easy installation on the legs or extensions of the profile strips, it is expedient that the inner dimensions of the receiving channel are larger compared to the outer dimensions of the legs only to the extent that is required for a simple Aufschiebevorgang.

If the entire lower cross bar is formed with two receiving channels designed to accommodate the extensions of the profile strips as one-piece delay element, the assembly of the delay element on the two legs or extensions of the moldings can be particularly time-saving, while at the same time the moldings or the legs by means of the cross bar , without any other connecting pieces in between, be firmly connected. In addition, the integral construction of the push-on element for both legs reduces the number of components of the holding device to be produced and stored.

In order to fasten the push-on element particularly reliably to the legs or extensions of the profile strips, in particular to be able to screw it, it can be provided that the receiving channels have on the bottom side a passage opening for receiving a screw. As a result, the delay element easily connected to the legs and even After prolonged use without increased force of this again be separated without the mounting screw would be disturbing visible. In order to provide space for the screw head between a substrate on which the holding device is placed, and the bottom of the receiving channels, the bottom may have at least around the passage opening an upward curvature or a corresponding material recess.

In order to be able to derive any moisture penetrating into the receiving channels and to be able to avoid possible damage to the legs or extensions of the profile strips, it is expedient for the receiving channels to have at least one outflow opening. The discharge opening is preferably arranged in the vicinity of the bottom of the receiving channels and extends particularly advantageously up to the top of the soil. Conveniently, a plurality, distributed around the circumference of the receiving channels arranged discharge openings are provided. If the delay element is made of plastic, the production of the delay element can be carried out particularly inexpensively. In addition, a push-fit element made of a suitable plastic offers good resistance to environmental influences and a stable connection of the at least one receiving channel with the at least one section of the lower transverse strip.

For a stable embodiment of the holding device, it is also advantageous if the transverse strip of the push-on element for receiving the lower edge of the rear wall has a groove-shaped depression. By the groove-shaped recess at least partially surrounds the lower edge of the rear wall, instabilities of the rear wall are avoided perpendicular to the surface extent when the receiving channel is pushed onto the leg or the extension of the profile strip. Even if the groove-shaped depression preferably extends along the entire transverse strip, the depression can also be arranged only in an arbitrary subregion of the transverse strip.

It is particularly favorable if the recess is a slot extending between a front and a rear web of the transverse strip, and at least one of the webs or one of the webs connecting bottom has drainage holes. The cross bar can thus be designed to save material with webs or a bottom, which are provided with openings as drainage openings in order to be able to dissipate any penetrating moisture into the slot can. A particularly favorable construction can provide latticed webs or a latticed floor.

In order to increase the stability of the holding device further, it can be provided that an upper cross bar of the receiving frame for the information carrier in each case at the upper, preferably frontal, end of the profile strip, preferably by means of a screw is attached. The upper cross bar thus connects the upper, preferably frontal, ends of the profile strips with each other, whereby a falling apart of the rear wall fixing Profileisten is avoided to the side. Although a screw connection for fastening the transverse strip to the profile strip is preferred, alternative or additional fastening means, such as snap connections, are also conceivable.

The connection of the profile strips with an upper cross bar and / or a delay element can be particularly advantageous if the profile strips each have a circular cross-section channel, which preferably has at its opposite ends in each case an internal thread. The internal threads are thus adapted to receive screws which are inserted through the upper cross bar or the delay element along a longitudinal axis of the circular channel. In this way, additional, to be attached to the profile lists fasteners for the upper cross bar or the delay element are not required. Instead, the circular channels can be made as part of the moldings.

When the channel is partially open on the circumference, the diameter of the channel is not necessarily limited to a predetermined value, so that screws vary depending on the flexibility of the walls of the channel Diameters can be screwed into the channel. In addition, can be saved by a circumferentially partially open design of the channel material, and easily remove any, penetrating into the channel, moisture.

For the connection of the profile strips with the rear wall, it is particularly advantageous if the profile strips each have a longitudinally extending, groove-shaped recess for receiving the rear wall. The rear wall can thus be advantageous, without additional fasteners, connected by insertion into the groove-shaped recess with the profile strips and thereby absorbed between them. The width of the groove-shaped recess can in this case be adapted to the thickness of the rear wall, so that the rear wall is slightly pressed into the recesses, or be designed to be larger in order to accommodate in a single type profile strips back walls of different thicknesses.

According to a further embodiment of the invention, it is provided that the profile strips each have a projection extending in the longitudinal direction, which has an axis for the pivotal mounting of the retaining strip. The axis preferably has a partially circular circumference, which is encompassed by a counterpart connected to the retaining strip.

The axis is in any case formed as part of the respective profile strip and there are no own steps for a separate production of a pivot bearing or its mounting on the profile strip required.

The design of the pivot mechanism can also be further simplified if the projection also has a groove-shaped recess for receiving at least one spring element, preferably a leaf spring. By means of the spring element, which is accommodated with one end in the groove-shaped depression, the retaining strip between an open, the placement of a poster on the rear wall enabling position and a closed, the poster on the rear wall by spring force holding position, be reliably pivoted. To connect the other end of the spring element with the retaining strip may also have a groove-shaped recess.

The invention is further achieved by a hinged poster stand with two holding devices according to the above description, in that the upper transverse strips each have at least one fastening device for a hinge connecting the two holding devices. The two holding devices can thus be pivotally connected to each other by means of at least one hinge, so that the poster stand can be stably erected without additional equipment when the holding devices are unfolded. In contrast, the poster stand can be stored to save space by folding the holding devices. The hinge may also have a spring element, which favors a folding of the holding devices in the unassembled state of the poster stand. In order to set up the poster stand stable, it is also advantageous if the hinge is designed for limiting the opening angle between the unfolded holding devices or additional, the holding devices connecting boundary devices are arranged.

The connection of the transverse strips or the holding devices to the hinge can be produced particularly advantageously if the fastening device has a slot opening for insertion of a leg of the hinge. The slot opening allows a reliable, circumferentially limited recording of a leg of the hinge.

In order to reliably hold the leg of the hinge in the longitudinal direction in the slot opening, it is preferably provided that the slot opening in the upper transverse strip crosses a passage opening for receiving a screw for connection to the profile strip. Thus, when the upper cross bar is bolted to the respective profile strip, hereby also the leg of the slot in the opening inserted hinge, which for this purpose has a correspondingly positioned through hole, bolted.

Fig. 1 shows a holding device 1 for an information carrier, not shown, for example, a poster P, with a two substantially vertical longitudinal sides 2, 2 ' having the rear wall 3, on which the poster P can be placed. Along the longitudinal sides 2, 2 'are connected to the rear wall 3 profile strips 4, 4' are arranged, which are each connected to a pivotable retaining strip 5, 5 'for holding the poster P. As in Fig. 1 is clearly visible, the two profiled strips 4, 4 'in each case beyond a lower edge 6 of the rear wall 3 outgoing and with the rest of the profile strip 4, 4' integrally formed extended to thereby legs 7, 7 'to form.

About the profile of the moldings 4, 4 'having legs 7, 7' can also be a in Fig. 1 integrally shown push-on element 8 are pushed, which a cross bar 9 and connected thereto, in the extension of the legs 7, 7 'extending receiving channels 10, 10' for at least partially receiving the legs 7, 7 'has. In particular, the push-on element 8 thus offers protection against mechanical or environmental damage to the legs 7, 7 'and can also be made visually appealing. Alternatively to the in Fig. 1 illustrated one-piece design of the delay element 8 could also be two, not shown, separate push members 8 may be provided, in which case each of the push-8 at least a portion of the lower cross bar 9 and a receiving channel 10, 10 'has. The cross bar 9 together with the retaining strips 5, 5 'and the profile strips 4, 4' at least part of a receiving frame 11 for the poster P or the rear wall 3. Separate devices for the connection of the cross bar 9 with the profile strips 4, 4th 'are therefore advantageously not required. To reliably connect the push-8 with the legs 7, 7 'and optionally also be able to solve this again, screws 12, 12' are provided, the bottom side through the receiving channels 10, 10 'in the legs 7, 7' are screwed can. Even if in the illustrated embodiment, the extensions 7, 7 'of the profile strips 4, 4' as legs 7, 7 'are formed and reach to the bottom of the receiving channels 10, 10' of the deferred push-8, could in another, not shown Embodiment, the receiving channels 10, 10 'be longer than the extensions 7, 7' of the profile strips 4, 4 'and thus serve as support leg extension, in which case the extensions 7, 7' of the profile strips 4, 4 'together with the receiving channels 10 slid onto it , 10 'legs make.

Fig. 2 shows in cross-section, by way of example for a receiving channel 10, 10 ', for the screw in the receiving channel 10, 10' provided on the bottom passage opening 13, 13 'for receiving the screws 12, 12'. In addition, at least one outflow opening 14 for the discharge of possibly in the receiving channel 10, 10 'penetrating moisture in the receiving channel 10, 10' is arranged. The drain opening 14 may be formed passing through the bottom or through at least one side wall of the receiving channel 10, 10 '.

In Fig. 3 the push-8 is shown in perspective in a front view and a rear view, wherein the delay element 8 is preferably formed symmetrically, with any front and back facing forward to the legs 7, 7 'can be arranged. The delay element 8 shown has for receiving the lower edge 6 of the rear wall 3, a groove-shaped recess 15, which extends in a preferred embodiment along the entire lower cross bar 9. The recess 15 is formed in particular as a running between a front web 16 and a rear web 17 of the transverse bar 9 slot. In order that any moisture which may penetrate into the depression 15 can flow away, at least one of the webs 16, 17 or a bottom connecting the webs 16, 17 has outflow openings 19. Although the recess 15 is shown extending along the entire lower cross bar 9, the cross bar 9 could also only each have a narrow, such as fork-shaped elevation at the front and back to the function of receiving the lower edge 6 of the rear wall 3 and dissipate moisture to fulfill.

Referring again to Fig. 1 the holding device 1 also has an upper cross bar 20, which Part of the receiving frame 11 is and in each case on the push-on element 8 opposite, frontal end 21, 21 'of the profile strips 4, 4', preferably by means of a screw 22, 22 ', attached. In this way, an even more stable embodiment of the holding device 1 is achieved.

Fig. 4 shows a view of a profile strip 4, 4 'of the holding device 1 in cross section. The integrally formed profiled strip 4, 4 'has a support channel 23 and a circular in cross-section, circumferentially partially open channel 24, each with an arranged at its opposite ends internal thread 25, 25', in which the screws 12, 12 'for attachment of the delay element 8 and the screws 22, 22 'can be screwed for fixing the upper cross bar 20. Between the support channel 23 and the circular channel 24, a groove-shaped recess 26 is formed, which is provided for receiving a longitudinal side 2, 2 'of the rear wall 3. In addition, the profile strip 4, 4 'has a projection 27 with an axis 28 for pivotal mounting of the retaining strip 5, 5' and with a groove-shaped recess 29 for receiving at least one spring element 30, preferably a leaf spring on. The profiled strips 4, 4 'formed in this way extend from their front ends 21, 21' to the lower ends of the legs 7, 7 'with a uniform profile.
