EP1607556 describes the door handle designed so that on the side of the grab handle opposite the first swivel axis a lever which is swivel mounted on the grab handle during swivel movement moves the grab handle from the closed and rest position in which the grab handle closes flush with the body and/or grip housing into the operating position where the grab handle protrudes for actuation, and at the end of actuating the door moves it back into the closing position. The lever is mounted on the grab handle to swivel about a second swivel axis which runs parallel to the first. - Door handle assembly and process for its use solves above referenced technical problem by attaching door handle to said door or door handle assembly base by at least one attachment means as well as providing a process during which safety features of said handle are utilized to prevent discomfort or even bodily harm of user of said handle.
- There are many door designs. Intrinsic to door design there is a handle for operating of said door, particularly for closing and opening of said doors. Said handle is usually seen to the outside user but in many instances said handle is flush with said door when not in use.
- This invention deals with a door handle which is normally hidden within the door, be it either completely flush with a door surface, or partially protruding from said door surface. If an user wants to use said handle, said user activates said handle using state of the art actuating means. Said user may either depress said handle, or triggers mechanism by some other means such as breaking a light beam, actuating proximity sensor, depressing a button or some similar mechanism.
- After said handle which has been hidden, either partially, or totally, within body of said door is activated, said handle emerges from a recess in which it was hidden. This can be achieved by means of springs, electric actuators, pneumatic cylinders, oil cylinders or some similar mechanism, or by rack and pinion mechanism as in preferred embodiment.
- After said handle has had emerged, said user may engage is by usually gripping it and proceeding with normal use of said handle.
- The problem which is solved by this invention arises when accidentally, or by design, reverse mechanism for hiding of said handle is actuated, but said user has not yet removed their hand from said handle. As a result of said reverse mechanism, handle is returning to its recess within said door body, and traps said user extremity or plurality thereof such as a hand, finger, or plurality thereof between said handle and edge of said recess. Such a situation may result in bodily harm or unpleasant experience of said user.
- It is therefore logical that some degree of safety must be provided for.
- This invention provides for at least one attachment means between said handle and substructure of said handle and/or door. In this particular embodiment, attachment means uses magnetic force.
- Below the invention is described in greater detail with help of figures, said figures forming part of this patent application.
-
Fig. 1 shows handle in its retracted position inside the door body, presenting handle (1), door body (2), the first magnet serving as part of attachment means (3a), the second magnet serving as part of attachment means (3b), handle connector (5). -
Fig. 2 shows handle in its extended position outside the door body, presenting handle (1), door body (2), the first magnet serving as part of attachment means (3a), the second magnet serving as part of attachment means (3b), base connector (4), handle connector (5). -

Fig. 4 shows handle in its retracted position inside the door body, presenting handle (1), door body (2), light emitting source serving as part of attachment means (3c), light detecting sensor serving as part of attachment means (3d), handle connector (5). -
Fig. 5 (a) shows door with handle in its extended position outside the door body presenting handle (1), door body (2). -
Fig. 5 (b) shows door with handle in its retracted position outside the door body presenting handle (1), door body (2). -
Figures 1 through 5 show door handle assembly and its process during operation with extending and retracting action performed by means of hydraulic or electric actuators. Said handle (1) is connected to handle connector (5). Said handle connector (5) is positioned onto base connector (4) allowing relative movement between handle connector (5) and base connector (4). Such arrangement provides for extending and retracting of handle (1) by sliding of said handle connector (5) up (to extend) and down (to retract) on base connector (4). In order for an assembly not to fall apart said handle connector (5) is attached to either door body (2) or base (6) with at least one attachment means (3). - Attachment means (3) for purposes of this application is described below.
- Said attachment means (3) can be composed of at least two parts, the first part being the first magnet (3a), the other part being the second magnet (3b), both magnets exerting force on each other (attracting one another) causing the handle to be retracted into the recess. Should an obstacle be placed between a handle and a recess, the handle ceases to retract without exerting undue force on the obstacle, said force being limited by magnetic force between both magnets.
- Further, in an embodiment which does not form part of the claimed invention, attachment means (3) can be comprised of a control unit, said control unit actively controlling said driving means (7), said control unit being controlled by sensor or plurality thereof. For example, there can be a light emitting source (3c), and light detecting sensor (3d). If an obstacle is placed between said light emitting source (3c) and light detecting sensor (3d), this is detected by said light detecting sensor (3d), sending a signal to said control unit, said control unit disengaging said driving means (7) to either remain at their present position, or engaging said driving means (7) to re-extend said door handle to extended position.
- Instead of sensor comprised of light emitting source (3c) and light detecting sensor (3d), said sensor can be proximity sensor positioned in such a way as to cover area between said handle and said recess, and detecting proximity of an obstacle, namely obstacle with infrared (IR) properties such as IR emitting hand or somesuch.
- Instead of proximity sensor, photocell sensor emitting electromagnetic (EM) radiation, and receiving reflected EM radiation (e.g. IR radiation) from said obstacle can be used in similar fashion to prevent damage to said obstacle.
- It should be stated that figure show a handle with two handle connectors. There is no particular reason for that, it is solely an embodiment. The same effect is obtained by single handle connector (5) connected to said handle (1), having single attachment means (3).
- Door handle assembly according to this invention is comprised of handle (1), said handle (1) connected to at least one handle connector (5), said handle connector (5) moveably connected to extending and/or retracting means by at least one attachment means (3), said attachment means (3) attached to door body (2) and/or base (6), said attachment means (3) allowing for relative movement between said handle connector (5) and said extending and/or retracting means during retraction of said handle (1) into a recess in order to limit amount of force exerted by said handle (1) on an obstacle between said handle (1) and edge of a said recess into which said handle (1) is retracted. In such a way user whose hand or finger or plurality thereof present an obstacle has on opportunity to remove his or her extremities without handle exerting too large of a force on them during retraction, if said user does not remove his or her extremities in time.
