Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a medical stretcher table intended for use in an ambulance car.

BACKGROUND OF THE INVENTION

These tables are used to hold the stretcher with an injured person for medical assistance. The desk consists of a pedestal that can be installed on a certain surface, eg on the floor of an ambulance car, and a platform on which the stretcher is placed.

Stretcher tables are usually installed permanently in an ambulance car and must be completely disassembled if necessary to remove them, for example when disinfecting the interior of the car.

SUMMARY OF THE INVENTION

The present invention relates to a stretcher table which can be adjusted to the desired position and returned to the original position.

The device according to the invention consists of a pedestal which can be rigidly connected to the floor, in particular to the floor of an ambulance car, and a platform for supporting the stretcher. It is characterized by having at least one sliding guide device adapted to allow lateral displacement of the platform relative to the pedestal. Thus, the table disassembly can be performed when the displacement lock device is in a locked state.

The table according to the invention is preferably provided with two sliding guide devices located at the distal ends of the table base.

It is particularly advantageous that the pedestal consists of at least one fastening plate which is installed on the floor and one longitudinal member is provided with a locking mechanism for joining and detaching the plate and longitudinal member. This allows quick and single operation to remove the table from the car. the lateral deflection of the platform relative to the base.

The locking mechanism can have a thumb on the mounting plate that is functionally connected! on the one hand, with the opening in the longitudinal member, and on the other hand with the actuating device.

The at least one retaining plate may be provided with centering pins which serve for lateral centering of the longitudinal member relative to the retaining plate.

The at least one sliding guide device may be provided with shafts connected to the platform and one element connected to the pedestal.

The element connected to the pedestal and the shaft support the weight of the platform during its transverse displacement. The element may be, for example, in the shape of a cone, fixedly connected to the longitudinal member.

According to a very advantageous way of realizing my bio-furnace device, the at least one displacement slide located parallel to the sliding guide device. Said bar has spacers which functionally correspond to at least one locking element.

The displacement adjustment bar is suitably connected to the lower platform leg. At least one locking element is disposed on a pedestal, e.g., on the longitudinal member, it is advantageous that the displacement adjustment bar is pivotable between the blocking position, at least one spacer opening being in contact with at least one blocking element, and when the bar is supported on the floor, keeping the stretcher table in position and unlocked between the positions, the spacing holes being released from the blocking element, and the bar no longer resting on the floor. In the locked position, the sliding guide device is fully or partially unloaded from the platform weight and the spacing holes prevent the transverse displacement of the atoll ·

In this embodiment of the invention, the locking is achieved by means of a mechanism that moves the at least one linkage, on whose hill at least one roller is located, towards the displacement adjustment bar. The roller has a functional relationship to the slanting profile of the bar and causes it to deflect. it further comprises a control pedal, the rotation of which causes the drawbar to be displaced, which is provided with an eccentric and is arranged so as to secure it when the pedal is set to the locking position.

At least one displacement adjustment bar has feet that support the platform against the floor. If lateral displacements of the platform are prevented by the blocking device, said feet maintain the weight of the platform and relieve the sliding guide device.

On the upper part of the platform, there may be a securing pin for holding the stretcher.

The invention also relates to a car equipped with a table as defined above.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of a section of the lower part of the table showing the function of the displacement blocking device, and FIG. 2b shows a section C-C of FIG. 2a.

DETAILED DESCRIPTION OF THE INVENTION

The table of FIG. 1 consists of a pedestal 12 and a platform 100. The pedestal 12 has two gripping plates 1, which are fixed at the distal ends of the table in apertures 16 in the floor 19 of an automobile. One of said gripping plates is provided with a thumb 14 which has a functional relationship to the opening 23 of the longitudinal member 2. On both distal ends of the longitudinal member 2 there is a bracket 21 in which the shaft 4 is inserted transversely. Each retaining plate 1 has two centering pins LL, which together with the corresponding pins 22 on each bracket 21 serve to correctly adjust the position of the longitudinal 2 and its bracket 21 relative to the retaining plates 1. while ensuring stability of the longitudinal 2. The vertical thumb 14 has a bevelled edge 17 and a vertical surface 18. The bevelled edge 17 allows the edge 24 of the longitudinal 2 opening 23 to be inserted on the vertical surface 18 of the thumb 14 when the longitudinal 2 is resting on the gripping plates The locking device 3 has a crank 31 and press! This also makes contact of the finger 14 with the edge 24 of the opening 23. In this way, the attachment plates 1 and the longitudinal member 2, which together form the base 12 (see also FIG. 2a), are joined together.

The platform 100 has an upper horizontal plate 101 with two bars 110 between which a locking pin 103 is mounted on the plate 102 and operated by a lever 99. Once the stretcher / not shown / slid over the bars 110 is placed on the platform 100. 103 and the stretcher is automatically locked on the table. By moving the lever 99 the stretcher is released and the injured can be evacuated from the ambulance car,

The top plate 101 is supported by a structure that consists of two arms 98, each with 114 and 115 tilt at each end, to be coupled to the bottom frame (97, 112) of construction. The deflected part of the arm 115 is connected to the lower frame by means of a beam 116, the beams 118 located in the lumped parts of the table contribute to strengthening the structure. The lower table frame is rectangular and consists of two longitudinal elements 97 and two cross members 112. on the one hand, in the 104 with the sides of the shaft 4, on the other, by both eyes 52, which, by means of the return springs 55, allow deflection of the displacement adjustment bar 5 upward (arrow F in Fig. 2a). 9, to the blocking position of the platform 100. at which feet 8 of the displacement adjustment bar 5 ee rest against the floor 19 of the ambulance car and thus carry the platform 100.a to the unlocking position when the displacement adjustment bar 5 ee deflects (approx. axes 52 by means of the return springs 55. thus no longer lean against the floor 19, allowing the platform 100 to transverse free movement, transverse sliding the platform 100 is due to the release of the shafts 4 in the brackets 21 of the longitudinal 2,

The operation of the displacement adjustment bars will now be explained in greater detail in FIGS. 2a and 2b,

The longitudinal member 2 has, at both distal ends and close to the salt 21, a housing 67 (FIG. 2b) in which at least one return spring pin 6 is located? so that the pin 6 is still pressed upwards, i.e., the spring urges the neck 66 of the pin 6, the displacement adjustment bar 5 has the shape of a folded and welded profile on the cut and is provided with spacing holes 51 on its underside 54. the upper ends 68 of one or more pins S. By sliding the pins 6 into the holes 51, the displacement of the platform 100 relative to the pedestal 12 is blocked.

The spacing holes 51 are not visible from above and are illustrated illustratively in FIG. 1. They are distributed along the entire length or part of the length of the displacement adjustment bar 5 to adjust the necessary position of the platform 100. The pedal 9 positioned in the center of one of the longitudinal elements 97 the lower frame (97,112) of the platform 100 has a wheel-shaped eccentric 95 into which the bent ends 96 of the linkage 91 are inserted in 94. The bent ends 96 are like a connecting rod freely rotatable in 94. At the opposite end, each linkage has a yoke 93 in at least one roller 92 is located. The return spring 97 (posed below 97) is guided by two elements (on at least one linkage 91) to allow the pedal to return to the unlocking position of the platform 100.

The displacement locking device operates as follows. Without actuating the pedal 9, the linkages 91 are in the released position and the rollers 92 allow the displacement adjustment flights 5 to deflect on the axis 52.Feets 8 are not in contact with the ambulance floor 19 and spacers 51 are outside The dispenser is moved by sliding the shaft 4 in the brackets 21. The healer adjusts the position of the table in the ambulance according to the need for the procedure. The rollers 92 ee support and press against the tapered profile 53 of the upper part of the slide adjustment rails 5 and cause them to deflect. As a result of the deflection, the feet 8 rest against the floor 19, slightly lift the platform 100 and at the same time one of the spacing holes 51 on the underside 54 of the displacement adjustment bars 5.K In order to ensure a certain and rapid locking, the spacing holes 51 are sufficiently wide and symmetrically spaced. The above operation can be used to lock the platform 100 transversely to the pedestal 12. The bent ends 96 of the linkage 91 extend beyond the center point when the pedal 9 moves. The weight of the platform 100 now rests on the feet 8a thereby relieving the sliding guide device (4.21) from most of the weight of the platform 100. The upper ends 68 of the pins 6 are seated in the spacing holes 51 and thus prevent any displacement of the platform 100, especially in bends.

Upon unlocking, the displacement guide bars 5 swivel on the axes 52 due to the return springs and the platform 100 ceases to be supported by the feet 8. The displacement of the displacement guide bars 5 is sufficient to release the upper ends 68 of the pins 6 from the spacing holes 51.

It will be noted, as a possible variant, that the shafts 4 could be connected to the longitudinal member 2, the brackets 21 are rigidly connected to the transverse element 112 of the lower part of the platform 100. The displacement adjustment bars 5 could be built to deflect relative to the longitudinal member 2 and pins 6 However, in this case, the advantage of relieving the sliding guide device from the weight of the platform 100 is lost.

According to another variant (also not shown), the spacer 51 is formed by means of a plurality of pins extending from the lower portion 54 of the slide adjustment bars 5, which in the present case are in functional relationship with the blocking hole located at both distal ends of the longitudinal 2 near the bracket 21. .
