Embodiment Construction

[0046] figure 1 Disclosing a first example of a screw retaining device 1 suitable for fixing screws 100, figure 2 The screw holding device 1 is shown when attached to a screw 100 and an attachment point in the form of an object. The screw holding device 1 comprises a connecting element 2 , here in the form of a tether, which in turn comprises a first end 3 , a second end 4 and an intermediate portion 5 connecting the ends 3 and 4 .

[0047] The first end portion 3 serves as a retaining portion and comprises an at least substantially circumferentially extending portion 6 which at least partially surrounds a retaining hole 7 which is arranged in contact with the screw to be retained. The thread 9 of 100 is engaged, and wherein the second end 4 is arranged to be attached to an object 8 . In this example, in order for the retaining hole 7 to engage said thread 9, the retaining hole 7 is flexible and has a released state, such as figure 1 As shown, the retaining hole 7 is subst...

Abstract

The present disclosure relates to a screw-retaining device (1) comprising a connecting element (2) which in turn comprises a first end part (3), a second end part (4) and an intermediate part (5) thatconnects the end parts (3, 4). The first end part (3) comprises an at least mainly circumferentially running part (6) that at least partly encompasses a retaining aperture (7) that is arranged to engage the threads (9) of a screw (100), and the second end part (4) is attached to an object (8). The screw- retaining device (1) further comprises a washer part (20) with a first and second washer portion (21, 22), having a corresponding first and second washer aperture (23, 24). The washer portions (20, 22) are connected and spaced apart by a gap (26), and the washer apertures (23, 24) admit passage of a screw stem (19). The first end part (3) is arranged to be positioned in the gap (26) before a screw (100) that is intended to be retained is mounted to the screw-retaining device (1) via the retaining aperture (7) and the washer apertures (23, 24). The present disclosure also relates to a screw-retaining kit.

Description

technical field [0001] The present disclosure relates to a screw retaining device comprising a connecting element which in turn comprises a first end, a second end and an intermediate connecting these ends. Background technique [0002] For some machines it is desirable or even required that a fastening element not be lost. One such application is, for example, guards or blade guards for moving elements in machines (eg cutting discs or cutting blades of cutting machines), transmission parts of engines or other moving parts. There may of course be other parts that may be covered for other reasons, for example to protect contact with thermal elements in the machine, or to prevent dirt or dust from entering machine parts. Guards, which are essential to the safety of persons using the machine, should be fully fastened, and in many cases screws are used. In general, it is also desirable to occasionally remove these protective covers to gain access to covered components, for exa...
