Definitions

  • the invention relates to a component for a cold room, comprising a clamping device halves consisting of two clamping device for connecting adjacent components by a clamping bracket and a corresponding thereto trained clamping bolt in the adjacent component.
  • Cold rooms require particularly good insulation in order to minimize the energy expenditure for cooling and to ensure that the temperature in the cold room does not increase, which could lead to the stored products such as food, medicaments, chemical substances or the like becoming unusable , For this reason, one sets such walk-in or non-accessible cold rooms of different sizes of insulated components as a kind of building block with appropriate thickness and insulation together.
  • These components are additionally connected to each other via clamping devices, so that cold bridges are avoided and an effective seal is created.
  • the cassette-type clamping devices are anchored in their position on the front side in the components when manufacturing the refrigerator with a corresponding clamping device in an adjacent component.
  • the actual connection is realized by a clamping bracket and a clamping bolt arranged in the adjacent component as a counter-holder. The hanger lays down with his bail arm around the bolt and is tightened, resulting in a firm connection; adjacent
  • clamping devices consist of two clamping device halves, which are connected to each other and thereby formed so that they have either a clamping bracket or a clamping bolt. It is disadvantageous that two different types must be made by clamping device halves and processed. This not only complicates the manufacturing process, but also the installation of the clamping devices.
  • the present invention has the object, a
  • each clamping device half has a receptacle for a clamping bracket and a receptacle for a clamping bolt.
  • the clamping bracket is designed in three parts and consists of a bail arm, an eccentric shaft and an axle. Accordingly, it is proposed that the clamping bracket is formed by a bail arm and an axle, wherein between the bail arm and axis an eccentric shaft is provided. Axle and eccentric shaft are used to allow the clamping by pivoting the tension bracket.
  • the axis is formed as a separate component which can be inserted from the outside into the clamping device.
  • the Walls of the respective clamping device halves recesses, in which the axis is used, wherein the bail arm and eccentric shaft are already used and then fixed by the same in their position with the same. The manual effort is extremely low, the installation is at the same time safe.
  • a positive connection is provided between the axis and the eccentric shaft.
  • This is expediently a toothing which transmits the torques both on the eccentric shaft side and on the side of the axle.
  • Overlying surfaces of the axis and the eccentric shaft are designed to be adapted accordingly.
  • a further advantageous embodiment of the invention provides that serves as the axis and eccentric shaft, a common component. It is therefore not about the formation of a thru axle, but an advantageous one-piece component, which is inserted into the two walls of the respective clamping device half.
  • the eccentric shaft has on its outer periphery a stop and on the end opposite the stop at least one frictional force on the bail arm practicing nose.
  • bail arm and eccentric shaft are inserted together in the clamping device half between the two opposite walls, then the axis is simultaneously inserted from the outside into the recess in the wall and in the eccentric shaft positioned therein.
  • the stop serves to ensure that the eccentric shaft finds its place in the recess in the clamping bracket.
  • Bail arm is fixed between the stop on the one hand and the nose at the opposite end of the circumference of the eccentric shaft on the other hand with a certain play.
  • the clear distance between stop and nose is dimensioned corresponding to the width of the tension bow. Characterized a frictional force is exerted on the bail arm on the nose, which causes in a particularly simple manner and virtually no additional components, the bracing between the bail arm and the clamping bolt in the opposite component. In particular, a previously necessary spring can now be omitted.
  • the nose has a rounding at its end facing the clamping bracket. This ensures, so to speak, a punctual friction and indeed at a defined point at the tip of the nose. The operating force during clamping of the clamping device is thereby reduced.
  • the eccentric shaft can be used only in a certain position in the recess, whereby in the first Line is prevented that this slip out of the bail arm when assembling the clamping connection.
  • An essential effect of the present invention lies in the good assemblability of the clamping device halves. This is also achieved in that the clamping bolt can be inserted from the outside into the clamping device, which should have corresponding recesses not only for the clamping bracket or the axis, but also the clamping bolt as an anvil for the clamping bracket. So the assembler determines when assembling the device as needed, whether the clamping device half such with a
  • Clamping bar or a bolt should be and uses the components accordingly.
  • clamping bracket and / or the clamping bolt between the spread walls of a clamping device half are used.
  • an adequate aid is to be used during assembly, by means of which the two opposite walls of the respective half can be spread apart, clamping jaws and / or clamping bolts are then used until they have reached their position with the axis in the wall-side recording.
  • This process can be facilitated if a path on the inside of the wall serves as an insertion aid for the clamping bracket and / or the clamping bolt, which opens into the receptacle.
  • This web is preferably arranged obliquely and makes it possible to guide the axis on the inside of the wall from the top edge, whereby comparatively less force needs to be applied to then reach the position in the recording.
  • At least one transversely arranged web is provided between the walls. This can absorb both normal forces, and act as a spacer between the two walls. On transverse load, however, the bridge is labile by correspondingly thin dimensions, so that it is destroyed when inserting the tension bracket and does not hinder this assembly process.
  • a particularly suitable variant provides that the web is formed integrally with the clamping device half.
  • the bridge is also made of plastic, so that no additional material needs to be used here.
  • a particularly advantageous embodiment of the invention provides that the recesses provided for the use of the tensioning bow or of the tensioning bolt are provided in the wall of the tensioning device with detachable covers and / or webbed webs.
  • This is not only advantageous in view of the fact that per chuck half either only the recess for a clamp or only for a clamping bar is actually used, but also in terms of the manufacturing process. In this case, it should be avoided that foam or other impurities can reach the interior between the walls of the clamping device during manufacture of the component with the tensioning device, which would render them useless. Instead, either the recess in the fixture wall for the clamp or that for the clamp bolt is made by removing covers or webs disposed thereon by piercing clamps or bolts.
  • the webs have at their outer edge a reduced thickness, which should facilitate the insertion of clamping bracket or bolt.
  • This area of reduced thickness then advantageously represents, at the same time, a seal after insertion of the stirrup or bow, in that the edge of the skin is applied to the stirrup or bar.
  • the composite of the two halves jig is exposed to particularly high forces, especially since a permanent solid connection between the halves to be achieved.
  • large forces act between the recesses in the wall of the tensioning device, which receive the tension bow or bolt and the connecting edges with which the tensioning device halves to be connected lie on one another.
  • struts are provided, the star-shaped arranged hincicd to the recesses are. These struts thus run virtually from the correspondingly reinforced recesses in the direction of the connecting edge and absorb some of the high forces that act between the clamping bracket and bolt.
  • clamping devices have connection connections at the ends of the connecting edges.
  • clamping device halves have this
  • Connection connections also at their ends facing away from the connecting edges.
  • the invention also relates to a two-part clamping device for a component for a cold room, comprising a clamping device consisting of two clamping device halves for connecting adjacent components by a clamping bracket and a corresponding thereto Clamping in the adjacent component, which is characterized in that each clamping device half has a receptacle for a clamping bracket and a receptacle for a clamping bolt.
  • Clamping device is provided for a component for a walk-in or non-accessible cold room, which is particularly advantageous in the manufacture of the clamping device and the assembly of the component, since it is virtually a universally applicable clamping device.
  • Each of these devices can serve both for receiving a tension bracket and a tensioning bolt. Only when installing must be determined which part function the device should exercise, it is no longer necessary to produce two completely different types of fixtures and vorzuhalten.
  • the assembly is very simple, by either bracket arm and eccentric inserted between the walls and then fixed from the outside by the axis, if it is a jig with clamp or the clamping bolt is, also from the outside, inserted into the wall.

  • FIG. 2 shows the three components bail arm 9, eccentric shaft 8 and 7 axis, from which a clamping bracket is composed.
  • the nose 11 is arranged at the end 12 of the circumference 30, which is opposite to the stop 10.
  • the jig of the bail arm 9 slides with the Recess 15 over the circumference 30 of the eccentric shaft 8, wherein the nose 11 here with the rounding 14 exerts a corresponding frictional force on the bail arm 9, so that a spring can be omitted as an additional component. Because of the high load in this area, the bail arm 9 is shaped separately in the section 16.
  • Figure 3 shows two strained individual walls 42 and 43 of two clamping device halves 1 and 2 in an interior view with the clamping bracket 3, which is pivoted about the axis 7 and is clamped in the end position with the clamping bolt 4. Because of the eccentric pivoting caused by the eccentric shaft 8, it comes to a tension of clamping bracket 3 and clamping bolt 4. Also on top of each other are the connection terminals 27, 28 at the ends 34, 35 of the terminal edge 23, 24th
  • connection terminals 38, 39 are shown in dashed lines on the opposite side 33 of the connection edge 23. Also shown in dashed lines is the outer edge 40, which is to be illustrated that the baying 18 need not be forcibly provided for anchoring the tensioning device in the device.

This is to be prevented on the one hand, that too high a force must be applied to pierce the web 21 with a clamping bar or strap, on the other hand serves the remaining web 21 at the outer edge 22 at the same time as a seal.
  • Figure 6 shows an eccentric shaft 8 with the attached clamping bracket 3, in which case in particular the distance a is illustrated.
  • the distance a on the one hand corresponds to the width of the tension bow 3 and on the other hand, the distance between the inside 19 of the stopper 10 and the end 13 of the nose 11 with the rounding 14, whereby an advantageous frictional force is exerted on the clamping bracket 3 during the clamping operation.
  • the one-piece clamping device half 1 can be seen in a perspective view. Approximately in the middle between the two walls 42 and 44 of this clamping device half 1 is the web 47 at its upper edge 48. This web 47 serves to keep the walls 42, 44 during foaming at a distance, but on the other hand destroyed at a relatively low transverse load as Figure 8 illustrates where the clamping bracket 3 is inserted. Can be seen in Figure 7 and 8 further, the guide rail 45 on the inner side 46 of the wall 44.
