Description

The invention relates to a plug-in individual parts existing range.

Such pallets usually include a plate, usually a flat, sheet-like part, and in opening receptacles used against the plate.

For storage and transport it is useful if the Pallets in individual parts, i.e. in plates and receptacles parts, disassembled to make them effortless when needed by inserting the receiving parts into the openings of the Put the plates back together.

Because single panels and a variety of individual As is known, receiving parts during storage and transport take up a lot of space and especially as individual parts are difficult to handle and incur costs, it is the object of the invention to put one together plug-in parts existing pallet and holding parts for to create such a palette to manufacture, Storage and transportation when not in use improve.  

This object is according to the invention by Creation of a pallet solved the following characteristics having:

• - A flat plate has at least one in one Opening arranged, essentially axially extending holding part on,
• - The holding part comprises a substantially vertical extending from one side of the plate Guide pin in for axial engagement sleeve-shaped end of a support member which is one of extending from one side of the plate Forms leg, foot or spacer, and
• - The guide pin is enclosed by an open one End to a free end tapered Hollow body parts for axial absorption corresponding hollow body parts of a second similar guide pin by plugging together.

Such a pallet thus includes a plate Openings, holding parts and support members, each Holding part has a guide pin on the one Support member can be pushed on. The openings in the Plate are spaced from each other and take one holding part each, each with a Support member can be provided. The support links can be used as legs or feet facing down serve on which the plate to form a Pallet supported for handling with a forklift. The support members can also be used as legs or Spacers serve so that there are several of the same type Allow plates to be stacked vertically one on top of the other Support members the vertical distance between define neighboring panels and thus prevent that the existing on the plate with the overlying plate comes into contact.  

According to a further feature of the invention, the Guide pin in the area of the free end one one coaxial to the axis of the guide pin Circular line lying on the side guide surface, the in a substantially complementary cylindrical Receiving the support member engages, the Guide pin at least two axial hollow lugs which is spaced apart on its circumference are arranged so that the approaches with their respective free ends in the receiving part of the support member intervene and those facing the center Shell surfaces of the approaches from one free end opposite open end tapered towards the free end run, everything in such an arrangement that two Similar holding parts are plugged into one another, whereby the approaches of the guide pin of the first holding part through the open ends of the corresponding second Holding part are included.

The plate has a flat structure and usually consists of a board - is also possible one frame - with two parallel to each other opposite surfaces, one of which is the Guide pin of the holding part axially protrudes. Each holding part is provided with a stop, for example a flange or a shoulder attached to a surface of the plate after insertion into the Opening bears against the holding part against displacement in secure the opening in one direction while resilient locking elements on the holding part, on the plate attack, moving the holding part, in particular of its guide pin in the opening of the plate in prevent the opposite direction.

The guide pin of a holding part is essentially a hollow body and designed and arranged so that several similar holding parts can be nested  are, the pin parts in the stack axially are nestable. Such an arrangement saves space during transport and storage and is consequently inexpensive.

This type of stacking is made possible by the fact that the guide pin preferably from two or more on The circumference of the axially annular hollow lugs exists, which is at a distance from the central axis of the holding part lie and have free ends that the insertion end form for the reception of the support members and the represent detachable connectors. The free ends the approaches are open axially opposite and are beveled towards the free ends so that the Tenon parts of two identical and in the same Direction of holding parts in the aforementioned Way can be nested, the Approaches of a holding part each through the open base the approaches of the associated holding part Are stackable. In the field of free ends of the cylindrical lugs are located lateral guide surfaces that are associated with the Inner wall of the support members in which they can be used are correspond. The sticking end of the Supporting members are usually cylindrical, e.g. B. a Pipe end, and in this case, those mentioned Guide surfaces formed as cylinder sections, the concentric to the inner wall of the intake of the Connect support links. The approaches point to the free end facing away, especially to the mentioned guide surfaces, openings on, into which the guide surfaces of the hollow ones are stacked Approaches of a similar assigned holding part come to lie.

The holding part can also have a second guide pin have the axially in the opposite direction  from the plate. That way you can the plate over the pin parts on both sides support members to be plugged on as spacers for over serve stacked panels in a stack.

The second guide pin is preferably coaxial with the arranged first guide pin and contains as the first guide pin ring-shaped on its circumference arranged hollow lugs with an open end, the from this to the free ends taper and as a guide when inserting one into the insertion end Serve as a support. The approaches of the second pilot pin are circumferentially spaced from each other and preferably with gaps in the approaches arranged of the first guide pin, so that the open ends of the lugs of the second guide pin in the axial direction, the approaches of a second on the circumference in can accommodate the gap inserted retaining part.

Further features of the invention result from the Subclaims.

The formation of the pallet according to the invention is very advantageous.

Before creating a pallet stack, be in the Usually several plates stacked tightly on top of each other transported or stored. When using the interlocking holding parts according to the invention you can namely several of the same and with plates fitted to the holding parts vertically stack one on top of the other, with those assigned to each other Pin parts of the holding parts of the above or below interlocking plate. Such a dense stacking of several with holding parts Plates is especially designed according to the usual use Pallets advantageous if the support members of the  Pallets have been removed, which is easy by pulling it out of the assigned pin parts he follows.

The invention is below with reference to two in the Drawing of illustrated embodiments of a Holding pallet explained.

Fig. 9 is a perspective view of a pallet stack without holding parts for storage and transportation.

The structure of a pallet 100 shown in FIG. 1 comprises a flat plate 1 , generally rectangular, made of rigid plastic or a board, with a bottom and a top surface 2 and 3 . In the plate 1 , a circular opening 4 is provided for receiving a holding part 5 in the form of an integral plastic molding. The holding part 5 has a base or extension 6 with an outwardly directed annular flange 7 . The base 6 merges into an axial guide pin 8 which has a coaxial cylindrical outer profile or guide surface 12 which is concentric with the flange 7 , for the purpose of a simpler description of the general structure, here at its free end. The cylinder profile 7 of the guide pin 8 is significantly smaller in diameter than the opening 4 . On the flange 7 or the base 6 extend in the same direction as the guide pin 8 radially spaced locking elements 9 . These are located on a circular line concentric with the guide pin and corresponding to the opening 4 . The locking elements 9 are arranged on the circle at a mutual distance and are biased radially outward with respect to the guide pin due to the flexibility of the plastic material connecting them to the flange. On the base 6 of the holding part 9 radial end stops 11 are provided between the guide pin 8 and the locking elements.

The holding part 5 can be inserted into the plate 1 . For this purpose, the guide pin 8 is axially guided by pressure on the holding part 5 through the opening 4 in the plate 1 , so that chamfered outer edges 10 of the locking elements 9 slide into the opening over the edge of the plate 1 and are thereby moved radially inward against their bias until the shoulders 9 a engage on the locking elements 9 over the upper surface 2 in the edge of the plate 1 ; see. Fig. 1. In this position, the flange 7 is fixed to the bottom surface 3 , so that the holding part 5 is secured against displacement in an axial direction in the opening 4 via the flange and in the opposite direction by the locking elements.

The holding part 5 of the pallet 100 is connected to a support member 13 made of plastic or cardboard in the form of a cylindrical piece of pipe. The free end of the pipe section 13 forms a cylinder liner 14 , the inside diameter of which corresponds to the outer diameter of the cylindrical guide surface 12 of the guide pin 8 . The pipe section is pushed onto the guide pin 8 with pressure until its lower end is firmly seated on the stop 11 of the holding part. In this position, the outer wall of the pipe section also bears against the latching elements 9 according to FIG. 1, so that these are secured against radial inward displacement and the holding part cannot lift off the plate 1 . The pipe section 13 thus comes into operative connection when it is plugged onto the guide pin 8 with the latching elements 9 and thereby presses them radially outward, so that they are held firmly on the cover surface 2 . By placing the pipe section 13 , the holding part is thus firmly and rigidly connected to the plate 1 .

The support member 13 can be of any length and can be used as a foot, leg or spacer, regardless of whether it points downwards or upwards, it serves as an abutment for supporting the plate 1 and enables the stacking of plates at a defined distance from one another.

The holding part according to FIG. 2 has a single guide pin 8 which can be arranged on a horizontal plate 1 either upwards or downwards, so that a support member is to be fastened plate-specifically directed upwards or downwards. For the stacking, in which several pallets are stacked vertically one above the other with the aid of support members, an intermediate part shown in FIG. 3 with double pins can be used as the holding part for the positioning. This intermediate part with double pin comprises the entire holding part 5 and additionally a second guide pin 8 ', which projects axially opposite the guide pin on the other side of the flange 7 . The guide pin 8 'is similar to the guide pin 8 and also has an outer guide surface 12 ' at its free end. This guide surface 12 'is a cylindrical surface with the same diameter as the cylindrical surface 12 and coaxial with it. To simplify the illustration, the pin 8 'is shown in dashed lines in Fig. 1 on the holding part. The intermediate part 20 with a double pin is a one-piece plastic part and is fastened to the plate 1 in a manner similar to the holding part described above, so that the latching elements 9 also overlap the top surface 2 of the plate 1 here . When using an intermediate part 20, a stack of pallets, according to Fig. 4 erected, the tubular supports and pallets having 100 and 200, wherein the first pallet 100, and the pallet is loaded 200 with the intermediate part 20 with the holding member 5. When stacking, the upper end of the support member 13 of the pallet 100 has a cylindrical receptacle 14 'into which the guide pin 8 ' of the intermediate part 20 of the pallet 200 engages. Another support member 13 is attached to the upwardly projecting end of the guide pin 8 of the intermediate piece 20 of the pallet 200 in order to enlarge the stack in this way. The base of the stack shown in FIG. 4 is expediently a foot part 21 , for. B. in the form of a cylindrical tube which is attached to the plate 1 of the lower pallet 100 coaxially to the support member 13 . The foot part 21 can engage, for example, in openings 23 in the plate 1 by barb-like approaches 22 . Optionally, the holding part 5 in the pallet 100 in Fig. 4 can also be replaced by an intermediate piece 20 with double pin, so that the downward-facing guide pin 8 'can engage in a receptacle on the top of the tubular foot part 21 . The foot part is therefore part of the pallet structure for handling by means of a forklift and is expediently connected to a plate 26 which forms a bottom surface, the forklift being able to engage between the bottom and top surfaces formed in this way. The foot part 21 is preferably firmly connected to the plate 1 , namely via the barbs 23 , in order to ensure that it does not fall off when the stack is lifted. Preferably, the tubular support members 13 and the foot part 21 form a continuous column passing through the stack, which has a considerable load-bearing capacity and prevents the goods 24 stored on the individual plates from being undesirably loaded. A continuous load path between the end of the support member, which bears against the stop 11 and the end of the adjacent support member, which bears against a shoulder 25 oriented perpendicular to the stop 11, which bears against the intermediate part 20 in, provides for the load transmission in the perpendicular to the support members 13 of the pallet 200 in FIG. 4. The pallets generally have a plurality of holding parts 5 , which are arranged distributed over the pallet surface, so that a stable stack of pallets can be erected in which a plurality of support members 13 pass through the adjacent plates in the stack.

A typical pallet stack with holding parts 5 , 20 corresponding to the position of the pallets in the stack is shown in FIGS. 5 and 6. In Fig. 5, the top and bottom plate of the pallets 100 are equipped with the holding parts 5 , while the plates 1 of the intermediate pallets 200 each have intermediate parts 20 , each with a double pin.

In the stacking configuration according to Fig. 5 and 6 is the to be transported and to be stored Good 24 from drums, rolls or coils. Each plate 1 carries five similar coils in a symmetrical arrangement according to FIG. 6 and accordingly it is expedient to arrange five support members 13 between each pair of plates of the pallet stack, one support member being in the center to prevent the coils from moving on the plate. If necessary, reinforcing struts 30 can be provided in the form of corner blocks between the respective floor and top surfaces 2 and 3 . These corner blocks preferably engage in corresponding seats 31 in the cover surfaces 2 and 3 of the plates 1 (cf. FIG. 7) and thus likewise form a continuous column over the stack, which in turn prevents loads from acting on the stacked goods 24 . The reinforcing struts 30 have notches 32 , in which lashing straps 33 for the pallet stack engage.

The plates 1 , holding parts 5 or intermediate parts 20 and the support members 13 are available to the customer as individual parts for the construction of pallets and pallet stacks. Such a delivery is less complex and inexpensive with regard to storage and transport, since this can take place in the non-assembled state.

In order to reduce the volume during storage and transport, the guide pins of the holding parts 5 and intermediate parts 20 are designed as hollow, internally conical shaped parts which can be inserted into one another.

From Fig. 2 it can be seen that the guide pin 8 of the holding part 5 is formed from several axially protruding, hollow shaped bodies or lugs 40 , here four lugs, which are arranged in a circle at a distance around the central axis of the holding part. Each attachment 40 is provided with a stop 11 in the region of the flange 7 and the locking element 9 . The approaches 40 with their stops and locking elements are identical to each other. Each attachment has a closed free chamfered end 41 , which serves as a guide part when inserting a support member into the end 14 serving as a receptacle, and an open end 42 at the attachment 6 of the holding part 5 . Each extension 40 also has, on the inside facing towards the center, from the open end to the closed end, bevelled outer surfaces that correspond to corresponding conical surfaces on the inside of another holding part; see. Fig. 8. In addition, each lug 40 has on its outward side a cylindrical lateral guide surface 12 which lies on a circular line concentric to the central axis of the holding part 5 and corresponds essentially to the inner cylinder surface of the cylindrical insertion end 14 of the support member 13 .

In the lateral surface of each extension 40 , an opening 43 is provided on the side guide surface 12 on the side facing away from the free end 41 .

Two holding parts 5 pointing in the same direction (according to FIG. 2) can be plugged into one another by inserting the free ends 41 of the lugs 42 of a first holding part into the open ends 42 of the corresponding assigned lugs on a second holding part, as shown in FIG. 8 . The two holding parts are then moved axially against each other, so that the four lugs of the first engage in the hollow lugs of the second holding part until the cylindrical guide surfaces 12 in the first holding part lie in the recesses 43 of the second holding part and the flanges 7 of both holding parts essentially parallel and lie concentrically on top of each other. Further holding parts 5 can be added for the formation of a pallet stack in the manner described above by inserting. The stackability of the holding parts is shown in detail in FIG. 8, in which the chamfers of the projections 40 designed as hollow molded parts and the manner of stacking with the cylindrical guide surfaces 12 in the openings 43 are clearly shown.

The intermediate pieces 20 in Fig. 3 have with respect to its guide pin 8 has the same configuration as a hollow body formed collars 40 as previously described for the holding member 5. The second guide pin 8 'namely also consists of four circularly spaced lugs 40 ', which are essentially identical to the lugs 40 , but mirror-inverted, so that the same parts are denoted by the same, but with dashed reference numerals. The approaches 40 ', however, no locking elements 10 are assigned and the stops 11 are formed by shoulders 25 . The approaches 40 'are axially offset from the approaches 40 , that is arranged on a gap. Accordingly, the open ends 42 'of the lugs 40 ' lie in the circumferential direction in each case in the gap between the lugs 40 and substantially in the plane of the flange 7th With this arrangement, a centering intermediate piece 20 with a holding part according to FIG. 8 can be stacked in the manner described above. In addition, two Zentrierzwischenstücke 20 may be nested by the lugs 40 of a first Zentrierzwischenstückes 20 engage axially into the open ends 42 of a second Zentrierzwischenstückes 20 and the projections 40 'of the second Zentrierzwischenstückes 20 axially simultaneously into the open ends 42' engage the first intermediate piece, so that both intermediate pieces are telescopically in the axial direction and the cylindrical guide surfaces 12 of the lugs of the first intermediate piece 20 are 40 in the openings 43 in the lugs 40 of the second Zentrierzwischenstückes 20 while the cylindrical guiding surfaces 12 'of the lugs 40' in the second Zentrierzwischenstück 20 in the Openings 43 'of the approaches 40 ' of the first centering piece 20 lie. Of course, a stack formed in this way can be expanded by further centering intermediate pieces 20 . In addition, the holding parts 5 or spacers 20 can be used in the axial direction for stack formation.

For a skilled in injection molding technology is clear from the description and in particular due to the design of the holding parts in FIGS . 2 and 3 that these with their hollow shapes and openings in the approaches 40 , 40 'and the hollow shape of the pin and Guide parts can be manufactured relatively easily by means of a compression molding process.

It can also be seen from the stacking of the holding parts according to FIG. 8 that this arrangement is always possible, even if the holding parts are not connected to plates 1 (the plates 1 are indicated in broken lines in FIG. 8). If the tubular support members 13 are removed after use of the pallets (namely, simply by pulling them out of the guide members), the pallets can be stacked vertically with almost no space, with the hollow guide members of the holding members intermeshing in a manner similar to that shown in FIG. 8. Such a pallet stack is shown in FIG. 9 and forms a relatively flat pallet structure 26 which can be easily stored and transported. For a simple creation of such a flat pallet arrangement, the holding parts 5 , 20 and the plates 1 can be provided with suitable markings, e.g. B. with raised lines on the flange 7 and the bottom and top surfaces of the plates 1 , which show the assignment of the plates and the holding parts to be connected therewith, so that it is ensured that the approaches 40 , 40 'of the holding parts are arranged so precisely are that they can be stacked on top of each other with the plates.
