QUICK PLUG-IN FASTENER

Abstract

A fastener comprises a receiving part comprising a housing defining a recess configured to receive a head of a plug-in part. The housing comprises at least two locking legs bordering the recess and pivotably mounted on the receiving part. The at least two locking legs each comprise an locking legs and extending along a spring axis. Movement of each actuating section toward each other acts to compress the spring member and open the recess to define an unfastened state. Once the head is inserted into the recess, release of each actuation section enables the spring member to exert a force along the spring axis to push the actuation sections away from each other and move each locking leg section to engage and retain the head to define a fastened state.

Claims

1-8. (canceled)

9. A fastener comprising: a receiving part comprising a housing defining a recess configured to receive a head of a plug-in part, wherein the housing comprises, at least two locking legs bordering the recess and pivotably mounted on the receiving part, wherein each of the at least two locking legs comprises, an actuating section, and a locking leg section, and a spring member positioned between the at least two locking legs and extending along a spring axis. wherein movement of each actuating section toward each other acts to compress the spring member and open the recess to enable the head of the plug-in part to be inserted into the recess and thereby defining an unfastened state, and wherein, once the head is inserted into the recess, release of each actuation section enables the spring member to exert a force along the spring axis to push the actuation sections away from each other and move each locking leg section to constrict the recess and engage and retain the head of the plug-in pail to define a fastened state, wherein the receiving part is coupled to one of: (1) a rope; (2) a belt; and (3) a rod to be connected.

10. The fastener according to claim 9, wherein in the fastened state, the actuating sections of the at least two locking legs extend obliquely upward and away from the one of: (1) the rope; (2) the belt; and (3) the rod coupled to the receiving part.

11. The fastener according to claim 9, wherein the at least two locking legs are pivotably mounted on the housing of the receiving part.

12. The fastener according to claim 9, wherein the actuating sections of the at least two locking legs are engaged by the spring member.

13. The fastener according to claim 9, wherein in the unfastened state, the at least two locking legs form a part of the housing of the receiving part.

14. The fastener according to claim 9, wherein the recess of the receiving part comprises an inner wall, and wherein the inner wall comprises a shape that is at least partially conical.

15. The fastener according to claim 9, wherein the housing of the receiving part comprises a cylindrical shape.

16. The fastener according to claim 9, wherein in the fastened state, a contact surface of the plug-in pan strikes against a connecting surface of the receiving part, and wherein the contact surface of the plug-in part is located on a collar surrounding a column of the plug-in part.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The invention will be explained in detail below with reference to an exemplary embodiment in conjunction with the drawing. In the figures:

[0011] FIG. 1 illustrates a schematic cross-sectional view of an embodiment of a quick plug-in fastener in a first position; and

[0012] FIG. 2 illustrates a schematic cross-sectional view of the embodiment of the quick plug-in fastener from FIG. 1 in a second position.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Referring to FIG. 1, the depicted quick plug-in fastener possesses a receiving part 1 with a housing 3 in which a plug-in part 2 can be inserted. FIG. 1 shows the plug-in part 2 in an uninserted state. Receiving part 1 and plug-in part 2 possess column-like attachments that are provided with suitable fixing apparatuses for connecting ropes, belts, rods, etc. as only schematically indicated at 5 and 6.

[0014] The receiving part 1 is furthermore provided with two locking legs 4, by the actuation of which the fastener can be opened and closed. These locking legs 4 each form a section of the w all of the housing 3 and extend by actuating sections 10 upward out of the housing 3. By manually moving the actuating sections 10 radially inward, the fastener is opened. By releasing the actuating sections 10, they are moved back by spring pressure into their initial position depicted in FIG. 1.

[0015] FIG. 2 shows the plug-in part 2 in an inserted state. It can be seen that a spring 9 mounted in the housing 3 presses the actuating sections 10 of the locking legs 4 radially outward, whereby locking sections 7 projecting radially inward of the locking legs 4 that are pivotably mounted at 11 are pressed radially inward. FIG. 2 shows a slate in which a plug-in part 2 with a mushroom head 8 has been inserted into a corresponding recess in the housing of the receiving part. In this state, the projecting locking leg sections 7 hook behind the mushroom head 8, w herein a plate-shaped section 12 of the plug-in part 2 lies against the bottom side of the housing of the receiving part.

[0016] To open the fastener, the two actuating sections 10 of the locking legs 4 are moved radially inward, whereby the projecting locking leg sections 7 are moved radially outward. This allows the plug-in part 2 to be pulled downward out of the recess in the housing 3. By releasing the actuating sections 10, the projecting locking leg sections 7 return back to their initial position in which they form a part of the wall of the housing 3 of the receiving part 1.
