DESCRIPTION:
BRIEF SUMMARY
The subject invention concerns a method of preparing a pipe, a hose or the like, such us e.g. hydraulic lines onboard a vehicle, a vessel or the like for securement thereof by means of a number of fasteners, such as e.g. clasps of plastics, metal or combinations of metal and rubber.
The subject invention likewise concerns a fastener adapted to be used in the manner indicated.
The majority of modern machinery adapted to perform bending and machining operations on pipes intended for use primarily within the car industry as a rule is so called CNC-controlled machinery. The fastener in accordance with the invention is arranged to be advantageously utilized in conjunction with the use of such machinery, the latter being fitted with suitable tools one single station or in several stations in succession, in order to perform the various operations involved.
The main purpose of the invention is to provide a method and a fastener which are suitable for use in conjunction with performing the machining referred to above, however, without necessarily being restricted to such use. The fastener is to be of such a nature as to allow it to be put in operative condition by means of only a small number of operational steps while offering good possibilities for determination of the position of the fastener on the associated pipe or similar means.
This purpose is achieved in the manner defined in the characterizing clause of claim 1 and by means of the device defined in the characterizing clause of claim 4.
The snap-engagement portion of the securement member in addition preferably is formed with an edge which faces rearwards as seen in one direction of insertion and one of the legs of the yoke-shaped clamp is formed with an edge which faces forwards as seen in the same direction, the insertion member in addition having a shoulder which faces forwards as seen in the same direction and which is spaced from said rearwardly facing edge a distance corresponding to the distance separating the forwards facing edge of the snap portion of one of the leg end portions of the yoke-shaped clamp from an abutment face on the end portion of the second leg of the yoke-shaped clamp when said clamp assumes its pipe-encircling position. Owing to this arrangement anchoring of the pipe may be effected in a very simple manner, possibly without a tool, while at the same time the yoke-shaped clamp is efficiently kept together in its firm and non-losable position about the associated pipe or the like.
The insertion portion of the securement member. in addition is a tongue, preferable of sheet metal and the recesses in the leg end portions of the yoke-shaped clamp are slits having a cross-section which essentially corresponds to that of the sheet metal tongue. This arrangement provides e.g. the additional advantage of minimizing the extension of the yoke-shaped clamp in the transverse direction of the pipe on the side of engagement or securement. This is of considerable importance, particularly when the space available for the securement or engagement is limited. Furthermore, the tongue shape, having an extension in the longitudinal direction of the pipe or equivalent means, attributes to it being possible to obtain a firm securement of the pipe.
Preferably the leg end portions of the yoke-shaped clamp comprise hook-shaped portions which are in cooperating interengagement as the clamp legs are pressed together, in order to hold the yoke-shaped clamp in position, at least until the securement member has been joined thereto. This arrangement facilitates the orientstion of the pipe or equivalent means with respect to the supporting structure onto which the pipe is to be mounted and onto which the securement member preferably has been previously mounted.
Preferably, the pipe-encircling portion of the yoke-shaped clamp has a non-round shape matching a non-roundness in the associated pipe. Owing to this arrangement the position of the yoke-shaped clamp may be determined very conveniently in a peripheral direction relatively the pipe on which the clamp is to
