12 Claims.
This invention relates to improvements in a combination door and supporting member, and more particularly to means operable by the movement of a door for automatically projecting and retracting a supporting structure, I
An object of our invention is to provide improved means adapted to be operated by the opening and closing of a door for projecting and retracting a step, shelf, tray or other supporting structure.
Another object of our invention is to provide an improved combination comprising a door, a supporting structure and means connecting the door and the supporting structure, whereby upon the opening and closing of the door the supporting structure may be first projected to a position where it is readily accessible and then retracted or moved to an out-of-the-way or concealed position.
A further object of our invention is to provide an improved door and step combination for Veh-icles, whereby when the door is opened the step may be automatically projected from a concealed or out-of-the-way position to one in which it is available for use by a person desiring to enter the vehicle through the door, and when the door is closed the said step is automatically returned to its initial or normal position.
Other and further objects of our invention will be pointed out hereinafter, or will be indicated in the appended claims, or will be obvious to one skilled in the art upon an understanding of the our invention herein shown and described is for the purpose of illustration only, and that therefore it is not to be regarded as exhaustive of the variationsof the invention; nor is it to be given an interpretation such as might have the effect of limiting the claims short of the true and most comprehensive scope of the invention in the art.
In the accompanying drawing:
Fig. 1 is a sectional view taken horizontally through a closed door having our projectible and retractable step operatively connected thereto;
' Fig. 2 is a similar view showing the door opened and the step in a projected position;
Fig. '3 is a sectional view taken on the line 3-3 of Fig. 1;
Fig. 4 is an enlarged detail view showing the spring pressed members which are located in the slotted arcuate bar carriedby the door.
Referring, to Figs. 1,, 2, 3 and l of the drawing,
the numeral I. designates a side wallof a, vehicle or other structure. having an opening which is normally closed by ahinged door 2.. The thresh-. old 3- of the door,,and, the. structure 3f: beneath. "and to the rear of it, are horizontally slotted or recessed as at 4,. andjwithin the same a step or supporting structure 5. is slidably and pivotally positioned. The end of the step .5 located adjacent the hinged side of the door is pivoted as at 6,,and the said step is adapted to be actuated when the door is opened and closed, first to a projected position, as shown in Fig. 2, and then to a retracted position, as shown in Fig- 1.
Secured as by a vertical extension 1 screwed to the door 2 near its hinged side is a horizontaltion is decidedly closer to the latter than tothe former.
' Carried'by the bar 1 and projecting into the slot lot" are opposed spring'pressed balls oryield able members 9 which are positioned fairly near that end of the slot located closesttothe door 2.
When the door 2 is ina closed position, the :pin 8 is positioned between the yieldable members 9 and that end of theslot 1a; located adjacent the depending vertical extension 1'. As soon as the door is slightly opened the slotted bar '1 is carried with it to a position whereby the iyieldable members 9 engage with the upwardly projecting pin 8 of the step 5. As the door is further opened the yieldable members 9 continue to engage with the pin 8, and as the bar I is bodily actuated'through a segment of a circle with the door hinge as a pivot, the step 5 is also pivotally actuated aboutits pivot 6 to a projected position. The free end of'the step 5 is provided with a protuberance 5' which is adapted to engage with a notch or stop member 3a on the I structure 3', thereby limiting the outward movement of the'said step. As soon as theprotuberance 5" of' the step 5 engages with the notch or stop member 3a, the outward. movement ofthe step is discontinued, and asthe door 2 is further J opened and the slotted bar 'I is also carried with it, the yieldable members 9 ride past the pin 8 to allow the said door to fully open. When the door is swung inwardly the step 5 is not moved inwardly until the yieldable members 9 are carried into engagement with the pin 8, and at that particular time the said door has already been almost closed. The final movement of the door to a closed position after the yieldable members 9 engage the pin 8 causes the step 5 to be carried inwardly to a fully retracted position.
When the step 5 is fully projected it remains in such a position, irrespective of whether the door is moved about its hinge either toward or away from the opening in the wall I it normally closes, providing, however, said movement in a direction toward the said opening is not sufficient to bring the yieldable members 9 of the slotted bar 1 into engagement with the pin 8 of the said step.
In the commercial embodiment of our invention suitable ball bearings or other anti-friction means is interposed between the supporting structure 5 and its mounting. The small and large circles shown by the dotted lines in Fig. 2 show, respectively, the arcuate path's described by. the pin 8 and the arcuate slotted bar 1 when they are moved about the pivot pin 6 and the door hinge during the opening and closing of the door. It is apparent that in place of the yieldable members 9 on the link I, other means may be used for releasably engaging with and actuating the supporting structure 5 about its pivot.
