Description

Foldable tea trolley or folding table

The innovation relates to folding tea trolleys and the like, including folding tables, which are in their normal open state have two surfaces on top of each other

The task of the innovation is to create a folding tea trolley or folding table of the kind that is easy and open can be folded up to a small extent

In British Patent 245,828 a folding table is described in which the upper tray afterwards when folded is folded down and the lower tray up. The design described in the cited patent has the disadvantage that the two trays are mounted so that they interfere with each other when folding, which is why the arrangement for folding the lower TabIeJ: ts upwards is complicated, since the lower Tabi

must be folded before the upper tray can be folded down

A later design is in British Patent 921,452 described «With this design springs are provided, which on the pivoting mounting of the lower tray act to load this up into its folded position «This requires the use of a lock, through Correctly hold the lower tray against the stress of the springs when the tea trolley is in it The open position is "Before folding up the tea trolley or the like" this lock must be released. "Outside" the upper tray is also locked provided that must be solved before the tea trolley can be folded. These locks do that Unfolding and folding the tea trolley difficult and is the upper tray of this design its support completely separated when folded.

The task of the innovation is therefore also to create a simple design of a collapsible tea trolley or the like, which can be quickly and easily folded or unfolded «No locks need to be released or in Are engaged and the unfolding and folding is done in a simple manner by, dB the frame parts of the tea trolley are pivoted because the trays are automatically guided into their correct position will.

The object of the innovation is therefore a foldable tea trolley or the like with two articulated U-shaped frame members and two trays arranged in this way are that in the normal unfolded state of the tea trolley, the trays between the two frame members one above and the other below the axis of the

steering connection of the frame members are mounted with each other, which in this state are mutually inclined and provided with stops so that they cannot open any further, while in the collapsed state of the two frame members, one is inside the other and the lower tray is folded up, but the upper tray is folded down, which two trays on one End or «are articulated in the vicinity of one end to the side parts of a frame member, and via an upper one and a lower supporting cross piece can slide, wich cross pieces are provided between the side parts of the other frame member, the articulation of the upper tray is further removed from the axis of the articulation of the frame members with one another in the collapsed state as the support surface of the upper cross piece and the linkage of the lower tray in the folded state is further away from the axis of the articulation of the frame members with one another than the bearing surface of the lower cross piece, so that when the tea trolley is folded up the top tray can swing down, taking it over the upper cross piece slides, while the lower tray by the sliding contact of the lower cross piece on this is pivoted upwards

Of course, in the case of a rolling table or tea trolley, unlike a folding table, swivel castors or the like are provided so that the tea trolley can be moved "

Two stops are expediently provided, which are located in are near the free ends of the undersides of the upper and lower trays and cooperate with the crosspieces to slide them against the trays limit so that the frame members are prevented from spreading beyond their unfolded position

To secure the lower tray in place when

the tea trolley is in the folded state, means can be provided. In a preferred embodiment of the innovation, this means for securing of the lower tray is formed by a lip provided with a stop which is arranged on the underside of the lower tray near the hinged end and in the folded state of the tea trolley cooperates with a safety part of the lower support that the Securing part in a recess between the surface of the Trays and the lip of the stop is held "

One embodiment of the innovation is described in greater detail below, for example in conjunction with the accompanying drawings described and show:

Fig. 1 is a perspective view of a foldable tea trolley od, the like;

FIG. 2 is a view of the tea trolley shown in FIG

in the vertical section, which is made in a plane parallel to the longer sides of the trays, and

Fig. 3 is an end view of the tea trolley shown in Figs. 1 and 2 in the collapsed condition.

The folding tea trolley shown in the drawings has two tubular metal frames 11 and 12.

The frame 11 has two parallel side parts 13 and 14 which are connected to one another by a handle part 15 are. Between the two side parts 13 and 14, a rectangular tray 16 is mounted by means of a metallic retaining bracket 17, which with the side parts 13 and 14 through Screws 18 and 19 are pivotally connected at a distance of, for example, 10 cm (4 ") from the handle 15. The tray

16 1st attached to the bracket 17 by screws 21. A Another tray 22 is between the side parts 13 and 14 at a distance of, for example, 58.5 cm (23 ") from the Handle 15 is mounted in a similar way by means of a second metal retaining bracket 23 and screws 24 and 25 *

The frame 12 is U-shaped and has two straight side parts 26 and 27 and a curved part 28. Connect two transverse rods 29 and 31 that are spaced apart from one another the side parts 26 and 27 together «

The frame 11 is mounted within the frame 12 by pins 32 and 33, which through the side parts 13 and 26 or « 14 and 27 are listed «

In the unfolded state of the tea trolley, the tray 16 is mounted above the tray 22 by the transverse rod 29, which is in a recess between the tray 16 and a lip 35 engages a stop 34 «The tray 22 is supported in a similar manner by the crossbar 31, which engages between the tray 22 and a lip 36 on a stop 37 "

The tea trolley is folded in that the frames 11 and 12 in opposite directions around the pins 32 and 33 are pivoted in such a way that the parts 15 and 28 are moved towards each other «The relative» length of the side parts 13 and 14 with reference to the straight parts 26 and 27 and the position of the pins 32 and 33 are chosen so that when the tea trolley is folded, the crossbar 29 becomes the retaining bracket

17 moves and the tray swings down to the pins 32 and 33, while at the same time the crossbar 31 to the Retaining bracket 23 moves (as indicated by arrow A- in Fig. 2) while the tray 22 is in the direction of the pegs 32 and 33 is folded, as indicated by the arrow A ₂ in Fig. 2).

In this embodiment, the lengths are the innovation for example 12 "from screws 18 and 19 to tenons 32 and 33, 30.5 cm (12 ") from tenons 32, and 33 to bolts 27 and 25, 27.3 cm (10 3/4 ") from crossbar 29 to pegs 32 and 33 and 24.8 cm (9 3/4") from the pins 32 and 33 to the connection points between the ends of the crossbar 31 and the side parts 26 and 27 of frame 12,

In Fig. 3 the tea trolley is shown in the folded state. The cross bar 29 is a straight bar between the straight parts 26 and 27, while the crossbar 31 has a securing part 38 and cranked bands 39 «In the unfolded state of the tea trolley are the Securing part 38 and the cranked ends 39 essentially in the same horizontal plane as that of the tray 22 occupied plane is parallel «In the collapsed state, the cranked ends 39 extend in a direction at an angle to the surface of the tray 22. The securing part 38 is located in front of the plane of the side parts 26 and 27 and in the plane of the side parts 13 and 14 and engages in a Recess between a lip 41 of a stop 42 and the tray 22, and holds the latter in its collapsed position. The tray is on a fold back down through the system of the securing part 38 against the Underside of the tray 22 as well as on a further flap through the abutment of the other side of the securing part 38 prevented against the lip 41 of the stop 42

The side parts 13 and 14 and the straight parts 26 and 27 have ind parts which are shown in FIG Are bent wise and form standing legs when the The tea trolley is in the unfolded state. Swivel castors or the like 43 are attached to these feet.

In another embodiment of the tea trolley, not shown in the drawing, the stops 42, 38 and
