BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a carrier device for a bakery, roast or other food product. This carrier is adapted for e.g. in an oven to support the plug so as to rotate or rotate about a substantially vertical axis that the wheels of the plug are lifted above and thus out of contact with a floor under the carrier.

On this floor, on the other hand, the pushchair is rolling on its wheels transportable to and from the carrier.

A prior art carrier of this kind, for rotatably and freely carrying a plug wagon over a furnace floor, has a combined member for the lifting of the plug truck and for its rotation at the ceiling of the furnace.

This combined lifting and carrying means has control elements which cooperate with other control elements on the top of the plugs to result in a control for the plug, so that the cart wheels are lifted off the floor during insertion of the plug in the carrier means. The force required to insert the carriage into the carrier means is manually applied in an area which provides a natural and convenient roof in the rear corner pillar of the carriage and is usually positioned slightly above the half height of the carriage. Since the lifting and running-in resistance to be overcome gives a braking force at the level of the driver, above the top of the plug, a tipping moment appears on the plug which easily results in such unevenness in the run-in movement of e.g. roasting cloud or gravy, splashes over the edges of the tubs, which are located on the plug.

It is also known that the control of an upper means arranged for rotation of the plug only provides the rotation protection necessary for the rotation of the plug, while the lifting devices which, in conjunction with an elevation, form a control in a vertical direction, are arranged on the underside of the plug-in truck and on the oven floor. Thus, in this case, a braking force resulting from the lifting resistance, upon insertion into the furnace, attacks the undercarriage of the plug car at a considerable distance from the propulsive force at the level of the handle, thereby producing a tipping torque and consequent disadvantages even in this known design for the carrier.

The object of the invention is to provide a support device such as when receiving a plug-in, it lifts under the influence of the manual drive-in force, but without causing any significant tipping moment.

This is achieved by providing the carrier with the features set forth in the following claim 1.

The invention will be explained in greater detail below with reference to the drawing, in which 1 is a side view of a pushchair and a hanger-shaped carrier according to the invention, wherein the plug is not inserted into the support but is resting on its wheels on the floor; FIG. 2 shows the carrier and plug of FIG. 1 is a front view; FIG. 3 is a sectional view taken along line III-III of FIG. 1 and shows the lower bend arm of the support device seen from above in plan section.

The trolley 1 is of a conventional nature to support a number of plates (not shown) with baked goods, roasts or other food products to be processed in e.g. an oven.

The carrier device 2 is adapted to, e.g. in an oven, supporting the plug so that it is rotated or rotated about a substantially vertical shaft line 3 with its wheels 4 raised freely hanging over the floor 5 of the oven, on which the plug is assumed to be able to drive on its wheels 4 to and from the carrier 2nd

A motion transmitting mechanism 6 is arranged on the carrier 2 to utilize the force which can be extracted from the manually propelled plug truck 1 introduced into the carrier, to effect the desired lifting movement.

The mechanism 6 has an abutment member 7 for the adjacent plug carriage 1. This abutment element is, in the design of the mechanism 6, resiliently substantially in a horizontal direction and arranged at such a height above the floor 5 that the plug which is inserted into the support device 2 contacts the abutment element. 7 at a location spaced from the upper and lower ends of the plug, Preferably, this impact point for the element 7 is located at about a height with a normal handle on the plug (e.g., around the rear corner post 8 of the cart) by pushing the cart manually in the usual way.

When the plug is manually pressed against the impact member 7f so that it is displaced horizontally, this movement is transmitted to the mechanism 6, which is in turn adapted to transfer the movement to a lifting member 9, 10 on the carrier 2, so that it lifts the plug.

Specifically, the support device 2 comprises a bracket 11 which is arranged for crank-like movement about said shaft line 3 and, in this regard, downwardly mounted in a floor-fixed bed 12 and upwardly has a shaft 13 by which it is driven (for rotation of the trolley) and stored in the oven ceiling. the bearing and drive devices at the ceiling are left out in the drawings. The bracket is further designed to accommodate the trolley 1 between its legs 14 and 15, the lower part 14 being substantially arranged along the floor 5 and having a height less than the ground clearance of the trolley in a central trolley portion which is located above the leg 14 as the carriage is driven into the hoop with its wheels on each side of the leg 14. This limited height is at least 4 along a distance from the outer end of the legs to such a depth in the hoop that wheel 4 still rolls toward floor 5 during its insertion into the shackle when it comes into contact with impact member 7. The shackle body 16 is telescopically adjustable in height for installation and operation reasons.

The movement transmitting mechanism 6 is arranged on the shackle 11. It comprises a lifting arm 17 which is pivotally secured in the body of the shackle 16 so that it is rotatable about a horizontal shaft 18. The lifting arm 17 extends with its upper portion above the shaft 18 from the shackle. body 16 is inclined upwardly toward the opening of the hanger, and has at its upper end the impact member 7. The swivel of the lever provides substantially horizontal movement toward the body of the hanger 16 as the plug is pressed against the impact member. The lifting arm 17 is as shown in FIG. 2 and 3, double formed with two equal arm parts, one on each side of the body of the bracket 16 and jointly arranged on the shaft 18. The upper arm has at its upper end its two identical arm parts together by the impact member 7 extending transversely and with its outer ends grip the plug. Devices for adjusting the gripping width are indicated in FIG. 2. The portions of the two equal parts of the lifting arm 17 located below the shaft 18 are connected at each side 19 to each connecting link 20. These two connecting links 20 run parallel to each side of the lower shackle leg 14 formed of two vertical plates , which is joined by a horizontal plate facing downwards, in the region of the bearing 12, and constitutes the connection of the shackle to the bearing.

The connecting joints 20 run with some movement in the vertical direction through each of their guide ears 21 on the hanger leg 14 and each carry a freely rotatable roller 10 which, as cam followers, cooperates with an upwardly extending cam 9 on the outside of the hanger leg 14. The lugs 9 and the lugs 10 constitute the previously mentioned lifting member 9, 10.

For lifting the trolley 1, when the cam followers 10 of the connecting links 20 are pressed up over the lugs 9, lifting rollers 22, one on each joint, are arranged. Each lifting roller 22 is freely rotatably mounted on a pin 23, which also supports one of the cam wheels 10. the lifting roller 22 is larger in diameter than the cam roll 10 and is located in the axial direction outside the cam roll 10 and is free of the cam 9. The two pins 23 are coaxially located and the lugs 9 are designed for synchronous lifting motion. Upon entering a plug 1, the lifting rollers 22 are located within the side flanges of a guide beam 24 arranged on the underside of the plug.

Claims (4)

A thrust roller 25 is positioned freely pivotally on a shaft on the lower strut 14, within the two lifting rollers 22 and at such a distance from it that it contacts the guide beam 24 of the plug car when the cam rollers 10 reach the highest point of the cam 9. The cam rollers are then lowered somewhat by taking a rest position in a recess in the respective cam. By removing a plug 1 from the carrier 2, the lowering to floor level can be achieved by the coupling engagement of the carriage with the impact member 7 being designed to follow the impact element for a while so that the cam rollers 10 leave their resting position and are then driven outside for the cam by the weight of the plug truck. It is also conceivable that with separate release means (not shown) directly affecting the lifting means or the motion transmitting mechanism, to allow the caster rollers to leave the resting position. in the embodiment shown, the movement of the lifting arm 17 towards the hanger opening is limited by a stop 26 on each connecting link 20. The stops 26 interrupt the movement upon impact on the respective guide ears 21. In a design with the carrier comprising a hanger of the type described, the lifting means must instead of , as shown and described, could be arranged to affect the entire lower leg leg by lifting, whereby this leg leg alone can be provided with rollers for the plug.
