Definitions
- This invention relates to securing deformable hoses on rigid cylindrical fittings such as those found in automobile engines.
- Hose clamps have been designed in a great variety of forms which fall into three general types.
- a first of these types is a continuous band which includes an upstanding portion or "ear" which can be deformed after assembly to tension the band around a hose.
- Such clamps are sometimes referred to as "Oetiker” clamps after the inventor.
- the clamps are engaged on a hose by using a special tool to deform the ear and thereby tension the band to apply a compressive radial stress on the hose.
- a second type of clamp includes a mechanical actuator, such as a worm screw, acting directly on a band to bring the band into firm engagement with the hose.
- the third type is a clamp of spring steel made to have a diameter slightly less than that of the outside diameter of the hose, so that when the clamp is deformed to enlarge the clamp, there will be stored energy in the clamp which can be released to apply a compressive radial force to hold the clamp on the hose.
- the invention provides a locating device for locating and holding a hose clamp on a cylindrical hose having a selected radius of curvature.
- the device has a resilient C-shaped clamp engaging element having opposed free ends defining a gap, the element being generally cylindrical about a first axis and the gap being smaller than an internal diameter of the element so that the clamp can be pushed through the gap and gripped by the element with radial projections on the clamp extending through the gap.
- a pair of resilient hose engaging elements are attached to the clamp engaging element and spaced axially with the clamp engaging element between the hose engaging elements which are proportioned to apply a load on the hose contained in the device to bias the hose away from the gap and into contact with the clamp at a location diametrically opposite the radial projections.
- the invention provides a locating device for locating a hose clamp loosely as a cylindrical hose having a selected radius of curvature, clamp being in an open position and the device having structure to engage the hose and the clamp to bias the clamp into an orthogonal relationship with the hose for subsequent actuation to clamp the hose, the device being characterized in that the device includes a generally cylindrical clamp engaging element arranged about a first axis and a pair of generally cylindrical hose engaging elements attached to the clamp engaging element, with the clamp engaging element positioned between the hose engaging elements, the hose engaging elements being arranged about a second axis parallel to said first axis and spaced from said first axis, the elements being resilient and terminating at free ends so that the elements are cantilevered from the clamp engaging element, whereby upon creating an assembly of the device and the hose clamp with the clamp contained between the hose engaging elements and within the clamp engaging element, the assembly can be engaged over the hose with the hose loose in the open clamp and the hose engaging elements deflect
- Fig. 1 is a perspective view of a hose clamp locating device according to a preferred embodiment of the invention
- Fig. 2 is an end view of the device shown assembled with an exemplary hose clamp (drawn to a smaller scale than that used in Fig. 1);
- Fig. 3 is a view similar to Fig. 2 after the device and hose clamp have been positioned on a hose and prior to release of the clamp to engage the hose. Best Mode for Carrying Out the Invention
- Fig. 1 illustrates a hose locating device designated generally by the numeral 20 consisting essentially of a resilient C-shaped central clamp engaging element 22 bordered by a pair of resilient hose engaging elements 24, 26 which are cantilevered by attachment to a central land 28 of the clamp engaging element 22.
- the elements 24, 26 run in opposite circumferential directions from the attachment to the element 22.
- the element 22 is intended to locate on a clamp and hold it in place while the elements 24, 26 are designed to draw the hose into engagement with the clamp and retain the clamp orthogonally with respect to the hose.
- the element 22 has a pair of clamp engaging arms 30, 32 which extend in opposite directions from the central land 28 and, together with the land, form the generally cylindrical element 22.
- the arms terminate at opposed free ends 34, 36 which define a gap 37.
- the gap is chosen to have a dimension less than the internal diameter of the element 22 for engagement on a clamp.
- Clamps usually are designed to include circumferentially spaced openings which are there to better distribute stress.
- an internal surface of the element 22 defines a pair of pegs 38, 40 which of course could be shaped differently if the openings in the clamp required it.
- the hose engaging elements 24, 26 are similar in shape but, as previously mentioned, extend peripherally from the central land 28 in opposite directions.
- the elements 24, 26 are generally cylindrical but of smaller diameter than that of the element 22, and the elements 24, 26 terminate in respective free ends 42, 44 normally located adjacent the respective connections to the central land 28 of element 22.
- FIG. 1 shows the clamp engaging element 22 disposed about a central axis 46 and the hose engaging elements 24, 26 disposed about an axis 48.
- the central axis 46 is spaced from the axis 48 which is nearer the central land 28.
- an exemplary clamp 50 seen in Fig. 2 is simply pushed through the gap between free ends 34, 36 and positioned so that conventional openings in the clamp (not shown) engage about the respective pegs 38, 40 (Fig. 1). Upstanding radial projections 52 on the clamp are then centered in the gap. These projections are exemplary of any such arrangements commonly used in clamps of this kind. In this case the elements are maintained in an open position by a clip 54.
- the clamp 50 is gripped between the resilient arms 30, 32 which were resiliently deflected as the clamp became trapped in the clamp engaging element 22.
- the assembly shown in Fig. 2 is now ready to receive a hose 56 as shown in Fig. 3. This is achieved by sliding the hose through the resilient hose engaging element 24, through the open clamp 50 and then through the other hose engaging element 26. Once in position, the hose comes under the influence of three forces.
- the hose engaging elements have been deflected in Fig. 3 and the energy stored in these elements causes downward forces (as drawn) to both sides of the hose engaging element 32. This creates a reactive load on the hose where it meets the clamp 50 and located between the hose engaging elements 24, 26.
- the axial spacing of these loads positions the clamp 50 orthogonally on the hose 56.
- the clamp uses stored energy to close the clamp around the hose thereby locking the hose on a rigid cylindrical fitting (not shown).
- the locating device 20 is passive and permits removal as if the device were absent.
- the device 20 can be of any suitable resilient material and is typically of Nylon (registered trademark) or glass-filled Nylon.
- the shape of the device can be changed provided that the clamp is held in the device and loads are applied to the hose to push the hose away from the gap and into contact with the clamp. These loads must be balanced to either side of the clamp in order to hold the clamp orthogonally with respect to the hose.
- the clamp engaging element must be made to match the size of the clamp which in turn is selected to be applied to a particular hose.
- the gap between the free ends 34, 36 should be less than the transverse dimensions of the open clamp in order that the arms 30, 32 deflect as the clamp is engaged in the device.
- the hose engaging elements 24, 26 are proportioned to be deflected by the hose sufficient to store enough energy in these elements to create the loading needed to hold the assembly on the hose in an orthogonal arrangement.
- the prestressed clamp has been used as exemplary of clamps generally.
- the device can be used with any hose clamp having the general form of a cylindrical main portion with radial projections to activate the clamp. Such variations are within the scope of the invention as described and claimed.
- the locating device permits pre- assembly with a hose clamp for subsequent engagement over a hose.
- the device grips the hose thereby aligning the clamp orthogonally on the hose to minimize the risk of actuating the clamp in an unacceptable orientation on the hose.
- the device is particularly suitable for use in automobile manufacture.
