DETAILED DESCRIPTION

(6) FIG. 1 shows a first embodiment of a retainer housing 1 according to the present disclosure for a door check. The retainer housing 1 comprises a housing part 2, which, in this case, can be seen in a sectioned view parallel to the longitudinal axis L of the housing part 2. As can be clearly seen, the hollow cylindrical housing part 2 has a cavity 3 which is provided for receiving a spring system and a brake body of a door check. The cavity 3 is delimited by an inner face 2a of the housing part 2. The housing part 2 has a first end 2b and a second end 2c, wherein a closing piece 4 is arranged at the first end 2b of the housing part 2, which closes the first end 2b of the housing part 2 or the cavity 3 on one side. An upper face 4a of the closing piece 4 has a plurality of circular depressions 5 and the lower face 4b of the closing piece 4 has accordingly corresponding circular elevations 6.

(7) In the embodiment of a retainer housing shown in FIG. 1, some of the elevations 6 are arranged concentrically about a center of the closing piece 4, wherein elevations 6 adjacent to one another have the same distance from one another. Furthermore, an elevation 6 is arranged in the center of the closing piece 4. The elevations 6 each have a flat stop surface 7, with which a spring system arranged in the cavity can be brought into contact and thus forms an abutment for the spring system. The stop surface 7 has a circular border and faces the second open end 2c of the housing part 2.

(8) In one side region, the housing part 2 has a bore 8 which runs parallel to the longitudinal axis L and said bore is designed for receiving a rivet pin shown in FIG. 3. The rivet pin serves on the one hand to connect the first housing part 2 and a second housing part and at the same time to fix the closing piece 4, in particular with respect to a rotary movement.

(9) On a lower face 2d of the housing part 2 there is provided a recess 9 which is T-shaped in cross section and in which a fastening part 10 made of metal is arranged in a positive manner. The fastening part 10 is expediently used for fastening the housing part 2 to one of the body part and the flap part of a vehicle, the fastening part 10 having an internal thread so that the housing part 2 can be fastened easily and safely via a screw connection.

(10) On an upper face 2e of the housing part 2, a hole 11 is provided, which serves to allow water that has accumulated in the cavity 3 to flow off. This advantageously prevents impairment of the functionality, in particular of the spring system and of the brake body preloaded by the spring system.

(11) Furthermore, two ridges 12 running parallel to the longitudinal axis L of the housing part 2 are provided on the upper face 2e, only one of the two ridges 12 being visible in the sectional view shown in this case. A resilient piece of material 13 shown in FIG. 2 can be pressed into the second end 2c of the housing part 2 between the ridges 12, the piece of material 13 serving as a stop buffer to dampen noises when closing the door.

(12) In order to prevent the piece of material 13 from being displaced in the direction parallel to the longitudinal axis L of the housing part 2, a web 14 running approximately perpendicular to the ridges 12 is provided on the upper face 2e. The piece of material 13 has a corresponding recess 13a on the lower face thereof, so that the web 14 is fitted into the recess 13a when the piece of material 13 is arranged on the upper face 2e of the housing part 2.

(13) FIG. 2 shows a second embodiment of a retainer housing 101 according to the present disclosure for a door check. Components that are structurally the same as those of the first embodiment in FIG. 1 are provided with the same reference signs, whereas structurally changed components have been given a reference sign incremented by 100.

(14) Compared to the first embodiment from FIG. 1, the closing piece 104 used in the second embodiment does not have a central elevation 6 in the center of the closing piece 4, but rather elevations 6 arranged equidistant from one another and circularly about the center of the closing piece.

(15) FIG. 3 shows the closing piece 104 of the retainer housing from FIG. 2 in a perspective view. As can be clearly seen, the closing piece 104 is designed as an embossing plate made of metal, wherein a nose-shaped projection 115 is provided on two opposing sides, wherein a bore 116 respectively is provided in the projection 115, which is used to guide the rivet pin shown in FIG. 4 or to fix the closing piece 104 in the housing part 2.

(16) FIG. 4 shows a preferred embodiment of a door check 30 according to the present disclosure. The door check 30 comprises the first housing part 2 shown in FIG. 2, a second housing part 20 being arranged opposite the first housing part 2, which is otherwise constructed in the same way as the first housing part 2. The two housing parts 2, 20 are connected to one another via two rivet pins 16, only one of the rivet pins 16 being visible in the cut-away view shown in this case. A coherent retainer housing 201 is formed thereby.

(17) In the cavities 3, 23 of the first housing part 2 and the second housing part 20, a spring system 40 and a brake body 50 are arranged, which are designed as half-open hollow cylinders, the closing end portion 50a thereof facing one another and protruding from the cavity 3, 23. A door retaining rod 21 passes through the retainer housing 201 formed by the first housing part 2 and the second housing part 20, the brake bodies 50 arranged in the cavities 3, 23 touching two opposing guide surfaces 21a, 21b and thus providing the desired braking effect.

(18) The braking member 50 has an inner hollow cylinder 50b which adjoins the end portion 50a and projects into the cavity 3, 23 and which is surrounded by an outer hollow cylinder 50c. The outer hollow cylinder 50c runs radially around a first end of the spring system 40 preloading the first brake body 50 against the guide surface of the door retaining rod, wherein the first end is facing the end portion 50a.

(19) The spring system 40 comprises a first helical spring 41 which rests in a positive manner on an outer face of the inner hollow cylinder 50b or runs around it. The first helical spring 41 passes completely through the braking member 50 and the second end thereof rests against the closing piece 104, which closes the cavity 3, 23 at a first end 2b, 20b of the respective housing part 2, 20 facing away from the end portion 50a. It is thereby achieved that the first helical spring 41 preloads the axially displaceable braking member 50 against the guide surface 21 a, 21 b of the door retaining rod 21.

(20) The spring system 40 further comprises a second helical spring 42, which has a larger outer diameter than the first helical spring 41 and which runs radially around the first helical spring 41. The second helical spring 42 rests with a first end on an inner face of the first end portions 50a of the brake body 50 and with the second end thereof on the flat stop surfaces 7 of the concentrically arranged elevations 6 arranged on the lower face 104b of the closing piece 104. This ensures that the second helical spring 42 also preloads the axially displaceable braking member 50 against the guide surface 21a, 21b of the door retaining rod 21, the preload being able to be set by setting or selecting the height of the elevations 6.

(21) A door check according to the present disclosure was explained above on the basis of an embodiment in which the braking members and the spring system are arranged or formed mirror-symmetrically to one another. It is understood that the two braking members, which are arranged mirror-symmetrically to the door retaining rod, can each also be preloaded against the first and second guide surfaces by different spring systems. In this case it can also be provided that the closing pieces used are adjusted accordingly.

(22) The door check according to the present disclosure explained above with reference to an embodiment is preferably intended for installation in automobiles. A first end of the door retaining rod is attached to a stationary body part so that it can pivot about an axis, and the second end of the door retaining rod is fastened to the pivoting door. The retainer housing, in which the braking members and the spring systems which preload them against the opposing guide surfaces of the door retaining rod are accommodated, is advantageously accommodated in an inner region of the door. As an alternative to this, however, a receptacle can also be provided in the body part.
