Abstract

Support frame, consisting of two longitudinal members (21) and two trusses (10), for receiving a loading surface forming plate, in particular for a trolley equipped with rollers, characterized in that arranged on the short transverse sides traverses (10) from a to Support frame to the center open U-profile (11) and an extension (12) of the lower U-leg consist, which has an arcuate, downwardly open curvature (13).

Description

The Invention relates to one of two longitudinal beams and two trusses existing support frame for receiving one a loading surface forming plate, in particular for a trolley equipped with wheels.

Dolly Of the type mentioned are often called platform trucks formed in which the surrounding the platform frame of a or more profile blanks is formed and with connection receptacles for other components such as castors or handlebars Is provided. Often platform cars have two castors and two fixed castors rotatable about fixed axes, which are arranged below the handlebar.

From the DE 39 17 279 C2 Transport trolleys or transport platforms with plug-mounted pipe supports are also known in which the coaxial with their respective pipe ends can be inserted into a plug-in sleeve welded to the frame of the trolley. However, such dolly have a relatively low load capacity.

It Object of the present invention, a support frame of the above specify the type mentioned, which is also suitable, higher Loads to withstand heavy goods. Furthermore, the support frame should be simple and inexpensive be produced.

These Problem is solved by a support frame according to claim 1, in accordance with the invention, on the short transverse sides arranged trusses from a support frame center towards open U-profile and an extension of the lower U-leg, the one arched, downwards open vault having. Further developments of this invention are described in the subclaims.

The The present platform has the advantage of high carrying capacity. In particular, the force resulting from the contact weight is over the loaded loading area on the traverse and, if that Carriage is part of a trolley, introduced to the rollers. This facilitates the handling of the trolley.

Of the Supporting frame creates also by the design of the Traverse large area Mounting options for attachments such as rollers, Central lock or directional lock.

To a further embodiment of the invention has the down open vault at least one, preferably three Incisions for receiving longitudinal bars. Such longitudinal bars serve to further strengthen the support frame, depending on the number the additional longitudinal bars used, higher Can absorb loads.

To a concrete embodiment of the invention is after below open vault in cross-section trapezoidal and has an upper flat roof surface below of the upper U-profile leg, wherein the distance is preferably the same is large the thickness of the insertable plate. This form of Vaulting allows the crossbeam to lightly out of one Sheet metal blank can be produced by bending deformation. The chosen ones Clearances allow a flush Completion of the inserted plate with the upper leg of the U-profile the traverse. Preferably, the traverse of a single Sheet metal cut are made, which is bent several times. The Side members will be followed by welded to the trusses, the traverses described connected with different lengths of longitudinal members can be different frame sizes manufacture.

Preferably has the downwards open curvature of the traverse to the Pages each have a recess which is at least one of the width of a longitudinal member has corresponding width. This construction helps stability to increase the welded support frame. Furthermore becomes a flush by the above measure Completing the side members created with the trusses.

To a further embodiment of the invention have the trusses integrated thread or retracting nuts on the underside for thread fastening from roller carriers to the assembly of a manufactured To facilitate transport trolley. Preferably, when used of the supporting frame in a dolly crossbars to the central Operation of two parking brakes in the open camber arranged, if necessary, on couplings or the like, what for wagons may be necessary, receives. Such attachments, which are arranged within the vault learn in particular Good protection against external damage.

After all have the upper U-profile legs holes as insertion for handlebars or pipe ends of supporting walls on.

The Support frames according to the invention are for different Transport equipment, in particular a platform truck, Table trolley or shelf trolley can be used.

Further Embodiments and advantages are shown in the drawings described. Show it:

1 a top view of a cross member of a support frame,

2 . 3 each side views of this Traverse,

4 a perspective view of the traverse after 1 to 3 .

5 a plan view of a support frame according to the invention,

6 a sectional view along the line AA,

7 a side view of the support frame after 5 and

8th a perspective view of the support frame after 5 to 7 ,

The in 5 to 8th shown support frame consists essentially of two arranged on the short transverse sides trusses 10 , two side rails 20 as well as three longitudinal spars 21 ,

The traverse 10 is made of a single sheet metal blank and bent so that they open to the support frame center U-profile 11 owns that one upper thigh 111 , One Base 112 , which serves as a sidewall, and a lower leg 113 which has an extension 12 with a vault that opens at the bottom 13 has. In this vault are on the sides recesses 15 and otherwise three cuts 14 arranged. The cuts 14 serve to accommodate the longitudinal bars 21 whereas the lateral recesses 15 for the introduction of the side members 20 serve up to the U-profile 11 pass. Here are the side members 20 on the tongue-shaped sections 18 the extension. To the side, the U-profile has a cap 114 which is shaped by bending. The traverse 10 as well as the side members 20 are welded together. The traverse 10 has a length L and a width B, wherein the edge lengths a and b of the U-profile (see 2 ) are the same length. The distance c of the upper leg 111 from the roof area 121 is equal to the thickness of an insertable plate. The distances d and e of the threaded holes 16 as well as the size of the threaded hole or the nut used f usually correspond to standardized distances from holes of the support plate for roles. The side members 20 have like the cross member a height h, wherein the longitudinal members in cross section have an L-profile.

• 1.) Direkte Krafteinleitung der Last über die Ladefläche auf die Rollen durch Ausgestaltung der Traverse.
• 2.) Leichte Rollenmontage eines Transportwagens durch die in der Traverse integrierten Gewinde oder Einzugmuttern.
• 3.) Vorbereitung für den Einbau von Lenkrollen mit Zentral-Feststellern und/oder Zentral-Richtungsfeststellern. Durch die erfindungsgemäße Konstruktion ist auch eine nachträgliche Umrüstung auf solche Rollen möglich.
• 4.) Einfache mögliche Traglasterhöhung durch Einsatz von Längsholen 21 als Verstärkungsunterzügen.
• 5.) Einfache Fertigung, da neben den Blechkantteilen für die Traverse nur glatte Profil-Zuschnitte benötigt werden und die Position der Schiebebügel oder Etagenbügel im Traversenteil eindeutig durch Bohrungen bzw. Ausstanzungen fixiert sind.
• 6.) Durch die spezielle Ausgestaltung des Tragrahmens kann eine für Etagenwagen identische Abmessung aller Ladeflächen erzielt werden.

The described support frame can be formed, for example, for different payload ranges. Possible maximum payloads are, for example, 600 kg, 1200 kg or 2400 kg, whereby the longitudinal profiles must be dimensioned correspondingly larger. The supporting frame is a welded construction with trusses 10 , which are made of sheet-metal edging for the front sides, and special profiles as side members 20 , which serve as longitudinal connectors. The trusses on the front sides allow the following advantages:

• 1.) Direct application of force of the load on the loading area on the rollers by design of the traverse.
• 2.) Easy roller assembly of a trolley through the built-in traverse thread or retracting nuts.
• 3.) Preparation for installation of swivel casters with central locks and / or central direction locks. Due to the construction according to the invention also a subsequent conversion to such roles is possible.
• 4.) Simple possible load increase by using Längsholen 21 as reinforcing beams.
• 5.) Simple production, since only smooth profile blanks are required in addition to the Blechkantteilen for the Traverse and the position of the handlebar or floor brackets in the truss part are clearly fixed by holes or punched.
• 6.) Due to the special design of the support frame can be achieved for a floor car identical dimension of all loading areas.
