Definitions

• the present invention relates to a hinge, in particular for a vehicle door, with two hinge halves which are pivotably connected by means of a hinge pin and of which the one, fixed hinge half consists of two parts which are detachably connected to each other and is intended for fixed assembly to the vehicle.
• the hinge pin is fixed in the moveable hinge half and can be fitted with its lower end in a lower part of the fixed hinge half.
• the upper end of the hinge pin is thereafter fixed with the aid of an upper part included in the fixed hinge half, which upper part is screwed securely on the lower part.
• the lower end of the hinge pin is moreover fixed in the lower part by means of a nut.
• One disadvantage of this design is that several loose parts, namely the upper part in the fixed hinge half and the screw and the nut must be handled and assembled.
• a further important disadvantage of this type of hinge, as in many other conventional types of hinges, is that it is necessary upon rehanging to accurately adjust the hinge parts before the door can be hung. Since the door is usually hung on a number of hinges, this involves the simultaneous adjustment of a number of hinges, which makes the hanging work- intensive, especially in those cases when the door is in addition heavy.
• the aim of the invention is to eliminate these disadvantages and to provide a hinge which is simple and is easier to handle upon hanging and rehanging of, for example, a vehicle door.
• This aim is achieved according to the invention by virtue of the fact that the one part of the fixed hinge half is pivotably mounted on the moveable hinge half by means of the hinge pin, and is locked relative to the moveable hinge half in the axial direction of the hinge pin, and by virtue of the fact that the hinge pin has a downwardly directed free end which can be axially introduced into an attachment on the other part of the fixed hinge half intended for fixed assembly to the vehicle, the two parts of the fixed hinge half being designed in such a way that, while the free end of the hinge pin is located in the attachment and thereby makes it possible to hold a vehicle door hung, they can be joined to or released from one another, by which means hanging or demounting of a vehicle door can be carried out without demounting the whole hinge.
• the attachment can advantageously consist of a lug projecting in the lateral direction at the bottom of the other part of the fixed hinge half. In this way it is easy, when rehanging the door, to hinge the latter securely.
• the lower end of the hinge pin is dimensioned so as to fit with considerable play in a hole in the attachment. This permits a simple hanging of the door without any need for accurate adjustment of the parts of the hinge relative to each other.
• the two parts of the fixed hinge half can be connected to each other by means of a screw connection, in which respect a screw can advantageously be screwed into the other part of the fixed hinge half.
• a hinge is obtained with fewer loose parts than previously, which considerably facilitates handling.
• the parts of the hinge are designed in such a way that a simple secure hinging of the door is possible upon rehanging of the door.
• Fig. 1 shows a perspective view of a section of a vehicle which is provided with hinges according to the invention
• Fig. 2 shows a side view of a complete hinge according to the invention
• Fig. 3 shows an exploded sketch of a hinge according to the invention
• Fig.4 shows a view, corresponding to Fig. 2, of an alternative embodiment of a hinge according to the invention.
• a vehicle door 1 is intended to be hung on a door post 2 in a vehicle body 3 with the aid of two hinges 4 according to the invention.
• the two hinges are separable.
• Each hinge 4 has a moveable hinge half 5 intended for securing on the door 1 and a fixed hinge half 6 intended for securing on the door post 2, which halves are joined pivotably by a hinge pin 7.
• the fixed hinge half 6 is in turn divided into two parts, a pin part 8 intended for the hinge pin 7 and a post part 9 intended for the door post, which parts are detachably connected to each other, for example by means of a screw connection, where a screw 10 is threaded into the post part 9.
• the hinge pin 7 has a downwardly directed free end 11, which is intended to be located in an attachment 12 projecting in the lateral direction and in the form of a lug at the bottom of the post part 9 of the fixed hinge half.
• the hinge pin 7 is mounted in the moveable hinge half 5 at two mutually separated bearing positions, an upper and a lower bearing position 13 and 14, respectively. If appropriate, bushings 15 and 16, respectively, may be situated at these bearing positions for the hinge pin 7.
• the pin part 8 is intended to be accommodated between the bearing positions 13 and 14, while, according to Fig.4 in contrast, it is designed to surround the bearing positions 13 and 14. This prevents the pin part 8 from being released inadvertently from the moveable hinge half 5.
• the moveable hinge half 5 consists advantageously of a bent metal part (see Fig. 3), which has been provided with suitable holes for retaining screws and hinge pin.
• a single, extended bearing position can be used, in which case the moveable hinge half 5 can, for example, be cast instead of bent.
• the hinge pin 7 is advantageously axially locked, and this locking can be effected in a number of different ways, for example by means of the hinge pin 7 being pressed into the pin part 8.
• the attachment 12 is designed with a continuous hole, the diameter of which is so much greaterthan the diameter of the free end 11 of the bearing pin that a considerable play is obtained between the hole and the end 11.
• both the hole and the end 11 can be essentially cylindrical.
• the hole and the end 11, or either one of them can have, for example, a conical or rounded form in orderto facilitate hinging of the door.
• the screw 10 advantageously has a conical section, the screw hole 17 in the pin part 8 having a corresponding design. In the hung position and before the screw 10 has been completely tightened, there is a radial play between the screw 10 and the screw hole 17.
• cooperating members on the pin part and the post part can of course instead be other types of cooperating members on the pin part and the post part in orderto facilitate correct hanging.
• hinges according to the invention will be used.to hang a vehicle door, hinges 4 mounted together according to Fig. 2 or 4 will be used, and the post part 9 of each hinge will first be fixed on the door post 2, for example by welding. Thereafter, the door 1 will be hung by means of the moveable hinge halves 5 being secured on the door by means of retaining screws, which are tightened when the door has been adjusted to the desired position.
• the door 1 can now be demounted easily, without any new adjustment of the position having to be made upon rehanging. This is achieved simply by means of separating the two parts 8 and 9 of the fixed hinge halves by removing the screws 10. The door can then be easily unhinged, i.e. the free end 11 of each hinge pin 7 is raised together with the door out of its attachment 12 (see Fig. 1). In the demounted state, it is now possible, with the aid of the free ends 11 of the two hinge pins 7, for the door to be hinged easily into suitable attachments in a fixture which is intended to hold the doortemporarily in the normal position.
• each pin part 8 is centred relative to its screw with the aid of respective guide surfaces, which have been exemplified above as a conical section on the screw 10 and a corresponding section in the screw hole 17. The door is thus rehung in the previously adjusted position.
• the radial plays between, on the one hand, the hinge pin 7 and the cooperating hole in the attachment 12 and, on the other hand, the screw 10 and the screw hole 17 are chosen in such a way that it is possible, upon rehanging, to make the screw 10 fit tightly in the screw hole with its threads, despite the fact that the door is only roughly secured.
• the plays are chosen such that, when the screws 10 are tightened fully and the door is situated in the adjusted position, the free ends 11 of the pins run completely freely in their holes in the attachments 12.
• the moveable hinge half 5 and the attachment 12 should advantageously also be axially separated with a certain play.
