Abstract

In an attachment for sales counters, in particular having an angled panel, joint heads are arranged at the upper end of upright fixed hollow profile supports, which joint heads fasten to connecting arms the upper end of a gas pressure spring which is arranged in the interior of the hollow profile and at that point finds a pivot point for its lower end. The panel can thus pivot between a folded-down position covering the interior of the counter and a folded-up position making the interior of the counter accessible. In order to facilitate assembly and demounting of defective gas pressure springs, it is proposed to connect the connecting arm releasably to the joint head, specifically in the folded-up position to make the handles freely accessible for engaging and disengaging this connection. As a result, the connecting arm with the connected gas pressure spring can slide conveniently into and out of the inside of the profile.

Attachment for counters, especially sales counters

The invention relates to a sales counter of the type mentioned in the preamble of claim 1. The gas pressure spring accommodated in the profile interior of the support has the task of facilitating the folding movement, securing this end position and damping the closing movement.
Io

The gas pressure springs are indeed in such counter attachments Protected inside the support profile and therefore not annoying to the outside, but the assembly is and Disassembly of the rod ends with the gas pressure springs is cumbersome and time consuming. If, in the event of a defect, a gas pressure spring needs to be replaced, so so far, the disc had to be dismantled in order to release the joint head in question from its support and to be able to remove the defective gas spring. The weight loosing. Positioning and adjusting the large disc is extremely time-consuming and energy-consuming.

The invention is based on the object of providing an article of the type mentioned in the preamble of claim 1 to develop, which enables a comfortable and quick assembly of its various components. this will achieved according to the invention by the measures set out in the characterizing part of the claim.

As a result of the detachability of the connection arm, various defective components can be easily removed and replaced with new ones without the need to remove the window as a whole from the sales counter. When the window is in the upright position, the relevant handles can be conveniently operated in order to couple or uncouple the connection between the joint head and the connecting arm. After uncoupling, the connecting arm can be detached from the joint head _t and the gas pressure spring linked to the connecting arm can be pulled out of the inside of the profile through the remaining cross-section at the end opening of the support next to the joint head. The folded-up disc does not hinder this process and is held in place by the neighboring rod ends. After this dismantling, the defective components, such as the gas pressure spring, can be replaced without the associated joint head having to be removed at the same time; on the contrary, the joint head can remain coupled to the disk so that it does not lose its adjusted position. After replacing the defective components, assembly is carried out in the opposite direction. These operations can be carried out quickly and easily.

A connection that can be handled quickly results from a plug connection between the joint head and the connection arm. Manipulation inside the profile is easy avoid if you change the plug-in direction of this connection during the coupling and uncoupling process in the direction of oriented towards the profile front opening of the column, what should happen with at least one component.

Such a plug connection can be secured by means of a threaded screw, which is expediently also points with its screw axis in the direction of the profile front opening. It is advantageous to change the direction of insertion

the connection on the one hand and the screw axis of the associated threaded screw on the other hand parallel to be arranged to each other, which has particular advantages during assembly and disassembly, as follows should be explained.

First of all, it is very useful to give the threaded screw a second function, namely to

To serve to secure the bearing position of the bolt, around which the joint head is pivoted at the upper end of the support. This is achieved when the threaded screw in the joint head can be screwed through to such an extent that it is with her

Bearing inner end is supported on this' bolt and thereby secures its position in the joint head. The bearing pin is thus held in bearing bores in the profile walls of the support without additional safeguards being required. If a threaded pin is used as such a screw, this ^{pin, which clamps the "1 J} " bolt, protrudes with its end piece from the joint head, serves to put on the connection arm with an opening provided on it and sets its coupling position through a screwable on the protruding end of the pin Nut tight. If the gas pressure spring is defective, it is sufficient to unscrew the nut without removing the threaded pin from its end position in the joint head. The threaded pin consequently holds the joint head unchanged in its adjusted position on the Lacjor bolt. Manipulations and adjustments of the joint head are Because of the aforementioned parallel arrangement between the plug-in direction of the connection and the screw axis of the threaded pin or its nut, it is also possible to exert a desired preload on the gas pressure spring

both on the side of the connection arm and on the side of the joint head connector parts and receptacles to use, which together like a toothing, works. When the parts are plugged into one another, longitudinal guidance is achieved from the outset. In case of a The use of set screws supports this guide in this area. You get a twist-proof Two-point attachment of the connecting arm to the joint head.

To install and remove a gas spring inside To make it easier to use a support, it is advisable to also connect the lower end of the gas pressure spring via a plug-in connection to be coupled with the support, for which all known plug connections can be used, e.g. the Connector pair fork opening - cross pin. A lateral auxiliary opening in the area in front of the lower one Fixed hinge point of the gas pressure spring facilitates assembly by means of a threaded pin, which is indicated in the description is to be dealt with in more detail.

Such a connection according to the invention can be rod ends of uniform basic training for one uniform set of supports, even if these are at different desired angles of inclination associated counter body should be mounted. You can namely the joint head with a wedge-shaped Block provided, the upper side of which can be processed as far as possible, depending on the inclination angle occurring in each case is that the top assumes a defined position and as an attachment surface for the attachment of a Disc holder is used. The pivot points of the gas pressure spring and the axis of rotation of the joint head take one

fixed position inside the column, regardless of how steep or how flat the column is runs. The only adjustment work is carried out on the joint head itself. The opening moment of the As a result, the gas pressure spring does not change when the column inclination changes. Working off the top the wedge-shaped block can be done by milling or grinding. When the disc is in the closed position, the joint head takes up always the same position at the top end of the column, regardless of the inclination of the column was chosen. No bevel cuts need to be made at the upper end of the column to adapt to the incline of the column to become. Cutting work is only required at the lower end of the support, where the Support length must be adapted to the respective requirement. At the top end of the column is therefore, regardless of the selected inclination, always the same size of the profile opening. A joint head can therefore be more uniform Cross-section dimension for all inclinations be used; the underside of its wedge-shaped block therefore covers the constant profile front opening at every angle of inclination.

In order to still move the joint head into a very far pivoted open position, which is a comfortable one Handling of the connection when coupling and uncoupling the connecting arm allows, it is advisable to use a Provide recess that separates the wedge-shaped block from a bearing piece, which on the one hand the pivot pin receives and on the other hand has the connector for the connection arm. In this recess namely, the profile wall of the support can be inserted in the upright position. Further measures and advantages of Invention are shown in the claims, the following description and in the drawings.

provided, at the free ends of each a joint head • is seated, which via a disc holder 15 holds the disc firmly connects to the joint head 14. The joint head is about an axis of rotation determined by a bolt 16 pivotable. When pivoting, the joint head takes the disk 11 mounted by the disk holder 15 with it and leads them into the flip-up position shown in FIG. 3. During the pivoting movement of the disc, there are still the following important components involved:

The supports 13 consist of a hollow profile, in the present case a rectangular profile. Inside the profile a gas pressure spring 18 is arranged, which in the usual manner consists of a cylinder and a propellant gas a piston movable therein via a piston rod. The gas pressure spring 18 strives to be in their To reach the extension position and therefore exerts a force in its longitudinal direction. The lower end of the Gas pressure spring is fixed via a stationary joint inside the support 13, for which in the present case, as Fig. 4 illustrates, a transverse pin 19 is used, which is in transverse bores in the side walls of the support stuck. The upper end 21 of the gas pressure spring 18 is connected to a connecting arm 23 via a hinge pin 22, which is releasably connected to the joint head 14.

In the present case, the joint head 14 consists of a wedge-shaped block 24, which has an arcuate Web 25 is connected in one piece with a special bearing piece 26. This bearing piece 26 is of an on Bearing bore 27, best shown in FIG. 6, is traversed into which, in the case of assembly, the bearing pin 16 is introduced, which is received in bearing eyes 28 in the profile side wall 29 of the support 13. The attachment

of the joint head 14 takes place via a threaded pin 3o which has a radial threaded hole 31 in the bearing piece 26 penetrated and is firmly clamped with its inner end 32 against the bearing pin 16. The inside end of the pen engages 32 in a groove 33 provided in the bolt, so that not only the joint head is fixed on the bearing bolt 16, but at the same time the bearing pin 16 is seated in the defined insertion position in the bearing eyes 28 of the profile. The two ends of the bearing pin can be covered by cover caps 34, which with shafts in Axial bores of the bearing pin 16 sit. The threaded pin 3o is long enough to make it even more special To fulfill coupling tasks in connection with the connection arm 23.

Between the connecting arm 23 and the bearing piece 26 of the joint head 14 there is initially a plug connection 35, which is designed in the manner of a toothing, namely, on both connecting sides from each other Complementary plug parts 36, 37 and plug receptacles 36 ', 37' exist, as can be seen from FIG. Between the wedge-shaped block 24 and the bearing piece 26 there is a recess 38 which allows the to retract the rear profile wall 47 when the pane is in the upward position as shown in FIG. 3. In this Fold-up position is through the plug parts and plug receptacles 36 to 37 'determined by the arrow 39 marked insertion direction on the front opening 4o oriented towards the profile. In the present case, this plug-in direction 39 runs parallel to the through the dash-dotted line in Fig. '3 indicated screw axis of the threaded pin 3o. The arm 23 still has a boom 43 provided with a hole 42 and, in the case of coupling, this boom hole 42 is on the one from the

Bearing head 14 protruding end piece of the set screw pushed and on the boom 43 is then screwed a nut 44, which the coupling of the Connection arm 23 on the joint head 14 secures.

The nut 44 is the essential handle for coupling and uncoupling the connecting arm 23. In the folded-up position, According to FIG. 3, this handle 44 is easily accessible; the nut can be removed without the clamping position of the threaded pin 3o on the bearing pin 16. Rather, the bearing pin 16 holds the joint head 14 and thus the disc 11 in its adjusted position. After removing the nut 44, the whole arm 2 3 from protruding end piece of the threaded pin 3o can be removed by pulling it against the arrow indicated indicated insertion direction 39 moves. The hinge connection at the upper end 21 of the gas pressure spring 18 remains unsolved, so that the gas spring 18, together with dome arm 23, can be easily removed. The arm can be grasped on the boom 43, which, according to FIG. 3, from the front opening 4o of the support profile 13 protrudes. Because also at the lower end 2o of the gas pressure spring one is even closer Descriptive plug connection 45 is present, with this pull-out movement, without additional dismantling measures, the entire gas pressure spring 18 from the profile interior 17 pulled out. Manipulation inside the profile is avoided. In the fold-up position according to FIG. 3, even the upper joint 22 of the gas pressure spring 18 in the profile interior 17 remain. From the dimension arrow 46 in Fig. 3 it can be seen that a sufficient residual cross-section next to the bearing piece 26 of the joint head 14 remains when the arm 23 is removed to the gas pressure spring 18 completely pull out. This means that the gas spring can be repaired or replaced outside of the hollow profile

take place. Installation is carried out in the opposite direction, for which the following measures are useful:

Outside the profile, the upper articulated connection 22 between the extension arm 23 and the repaired or new gas pressure spring 18 executed. Then this will Assembly pushed through the front opening 4o in the area of the mentioned remaining cross-section 46 into the profile interior 17, because the tightened pivot pin 3o is the bearing piece 26 and thus the entire joint head 14 unchanged in its storage position on the bearing pin 16. It would now be conceivable in the area of the lower Provide fixed bearing 19 for the lower end 2o of the gas pressure spring 18 guide surfaces, which in this Insertion process the lower end of the spring 2o automatically in the exact storage position via the aforementioned plug connection convict. Such internals are expensive and. can also be avoided by taking the following additional measures. The plug connection 45 consists in the present case at one end only from the already mentioned cross pin 19, which is fixedly arranged in the profile interior 17 of the support 13 and from a fork opening 48 on the can be seen in FIG Lower end of spring 2o. Instead, other plug-in connection elements 45 known per se could of course also be used such as a ball socket and a ball. So that in the present case the fork opening 48 den Cross pin 19 meets, one uses an assembly pin 49 shown in FIG. 3, which passes through an opening in the front profile wall 51 of the support 13 can be introduced after this opening 5o normally sealing cap 52 has been removed. With this mounting pin 49, in the direction of the arrow 53 is inserted, the gas pressure spring 18 is so far pressed against the opposite profile wall 47 during gas spring installation that the lower end 2o at the

Moves along the inner surface of the wall and with security on the Cross pin 19 hits. In this installation, the hole 42 in the arm 43 of the connecting arm 23 is again via the . protruding end piece of the threaded pin 3o pushed and can now also be secured by the nut 44. The connector parts 36 are of course leading the way, 37 and the plug receptacles 36 ", 37 'of the upper plug connection 35 engaged. Now the connecting arm 23 forms a joint head 14 that is connected to it again Whole. Now the disk 11 can again ■ be transferred into its closed position 11 without Adjustments to the disk holder 15 would be required.

In the exemplary embodiment in FIGS. 2 and 3, the pane holder 15 consists of a section of a U-profile 54, into the U-space of which the longitudinal edge area of the pane 11 is inserted and glued, as can best be seen in FIG. This profile section 54 extends in the plane of the support 13, which, as the right part of FIG. 6 shows, can also be designed as a double support 13 ' ^x . This double support 13 'is provided in the middle of the bar, where two adjacent disks 11 collide, so in their double rod ends 14 and associated components are provided in a double, the profile section 54 is at an on top of the wedge-shaped block ^24: fixed provided for attachment surface 55 , the ,, corresponding to the rear end region of the cranked disc 11 extends horizontally. This is of particular importance in connection with the inclination of the support 13, which will be explained in more detail in the end. ^{x x} -

In Fig. 5 a different disc holder 15 'is shown, which is composed of a two-part fastening rail 56, 57, which the to a disk 11 belonging adjacent joint heads 14 connects to one another, that is to say extends perpendicular to the plane of the supports 13. One rail part 57 is on the already mentioned horizontal attachment surface 55 of the wedge-shaped block 24 attached and has a tilting joint 58, opposite the upper rail part 56, by means of suitable profiling, so that this is pivoted like a lever by an end grub screw and in the manner of a claw the rear longitudinal edge of the disk 11 is pinched between the two rail parts 56, 57. As can be seen from Fig. 5, the profile also has an opening 59 in the profile side walls, through which a locking pin can be inserted, which is shown in Fig. apparent insertion position through the recess 38 in the joint head 14, but at an edge of the bearing piece 26 comes to the plant. With the locking pin inserted, the disk 11 can consequently no longer be opened swivel up. A corresponding safeguard could also be present in the fold-up position.

The support 13 is at a desired angle of inclination 6o on a plate 61 of the counter body 12 over a mounting block 62 is attached, as can be seen from FIGS. 2 and 6. For this purpose, the plate 61 has the top a slot 63 into which the mounting block is inserted and inserted through a slot on the underside Cylinder screw 64, which engages in a threaded hole of the mounting block 62, is tightened. The mounting block 62 also has transverse bores for the passage of fastening bolts 66, which are in corresponding openings engage in the support 13 and thereby the support 13

hold in the inclined position. For this purpose, the support is cut at its lower end 67 in accordance with _unc 3 taking into account the desired tilt angle 60 cut at an angle. In the area of the upper front opening 4o, however, no cutting work has to be carried out on the support, because all adaptations in the invention can advantageously be carried out on the wedge-shaped block 24, as will be explained in more detail with reference to FIG.

At a given angle of inclination 60 of the support 13, the wedge-shaped block 24 has a wedge angle 68, the above mentioned attachment surface 55 in a horizontal position, parallel to the rear edge

Now a steeper angle of inclination 60 is selected, the top of the wedge-shaped block 24 is to be worked off to such an extent that this new one The angle of inclination of the wedge angle is reduced to a smaller value 68 'indicated in FIG the new attachment surface 55 'in the dashed lines in Fig. Indicated.

Location. For this reason, a basic profile of a wedge-shaped block 24 is assumed, which is designed for the flattest possible prop inclination and with a correspondingly desired steepness the support undergoes the described processing by milling or cutting on the top side.

Because the upper front opening Ao of the support profile 13 is not changed even when the inclination is changed, there is a constant opening that is always covered by the underside 69 of the wedge-shaped block 24 without protruding and without a gap. The plug-in direction for coupling the plug connection 45 at the lower end of the spring is marked in FIG. 2 by an arrow which is directed towards the upper front opening 4o of the support profile.
