Definitions

  • the present invention relates to a hose clamp solution for water systems of whirlpool baths.
  • Water systems for whirlpool baths generally comprise a plurality of water-jet outlets connected to the side walls of the tub such that water can be pumped into the tub.
  • the water-jet outlets are therefore interconnected with a water-carrying circuit in order to pump water into the tub.
  • the water-carrying circuit typically comprises one or more water pumps, pipes, hoses, and different kinds of joints.
  • the water-carrying circuit therefore comprises a large number of couplings where for instance a hose is connected to a pipe branch on a water-jet outlet or on a T-shaped joint. These couplings need to be sealed in order to prevent leaking from the water-carrying circuit. It is known that the sealed coupling of a hose to a pipe branch can be achieved by various methods, from simple gluing to mechanical clamping with clips.
  • the water-carrying circuit is often very complex and comprises a large number of sealed couplings.
  • the water-carrying circuits therefore need to be assembled manually which is a very time and cost consuming process because many hoses and pipe branches need to be connected through a sealed coupling.
  • CA 989597 describes a hose clamp fro clamping a hose to a pipe branch.
  • the hose clamp comprises an open-ended hose surrounding band with a interlocking clamping assembly comprising a first and a second interlocking part.
  • US2006/0130285 A1 discloses as hose clamp similar to the one disclosed in CA 989597; however, the hose clamp disclosed in US2006/0130285 further comprises a C-shaped inner band having flexible arms.
  • the C-shaped inner band can be snapped/clicked onto the hose prior to clamping the hose to the pipe branch.
  • the problems concerning the adjustment of the hose clamp position still apply to this type of clamp.
  • EP1134474A1 describes an insert coupling for connecting a flexible hose to a pipe.
  • the pipe comprises a housing with a bore and the insert coupling is mounted in the housing.
  • the insert coupling comprises a clamping bush and a clamping ring comprising projecting teeth, and the clamping ring is adapted to be inserted inside the clamping brush.
  • a hose can be inserted into the insert coupling and the insert coupling would prevent retraction of the hose. This is achieved because the clamping bush is adapted to push the projecting teeth into the hose jacket when the hose is retracted.
  • Lubrication such as oil, soap, vaseline, etc. needs to be provided at the outside of the hose in order to insert the hose into the pipe housing.
  • the object of the present invention is to solve the above described problems.
  • a hose clamp for clamping a hose on a pipe inserted into said hose, said hose clamp comprising a hose-surrounding and clamping means, said hose clamp is adapted to be positioned around said hose for clamping said hose on said pipe where the hose clamp comprises pipe attachment means adapted to attach said hose clamp to said pipe prior to inserting said pipe into said hose and clamping said hose to said pipe.
  • the pipe attachment means makes it possible to premount the hose clamp at the pipe prior to inserting the pipe into the hose.
  • the premounting could for instance be done by a machine at the pipe and hose clamp manufacturer such that the whirlpool installer does not need to mount hose clamps at the pipe.
  • much time is saved when a person connects hoses to pipes due to the fact that the person only needs to insert the pipe into the hose and thereafter clamp the hose clamp.
  • the hose-surrounding surrounds at least a part of the hose and has an inner surface that is substantially aligned with the outer surface of the hose.
  • the hose-surrounding comprises an open-ended band
  • said clamping means comprises at least two interlocking parts.
  • the clamping process is further simplified because the hose clamp could be clamped very tightly and fast.
  • the open-ended band makes it possible to tighten the hose clamp because the inner circumference could be reduced due to the fact the ends of the open-ended band could over lap when the two interlocking parts engage with each other.
  • At least a part of the hose- surrounding has a smaller inner circumference compared to the remaining parts of said hose-surrounding. This causes a tighter clamping of the hose because the clamping force obtained by locking the interlocking parts would be applied to a smaller area of the hose.
  • the hose-surrounding further comprises a number of spikes adapted to fix the surface of said hose when said hose clamp is clamped, such that said hose is retained inside said hose- surrounding.
  • a number of spikes adapted to fix the surface of said hose when said hose clamp is clamped, such that said hose is retained inside said hose- surrounding.
  • the spikes could be made of the same material as the hose-surrounding, e.g. plastic, and be constructed by injection molding. However, the spikes could also be made of metal spikes molded into the plastic.
  • the pipe attachment means comprises at least one support surface extending transversally relatively to the inner surface of said hose-surrounding.
  • the hose clamp could easily be positioned in a longitudinal direction being the direction along the hose and pipe fitting, because the transversally extending support surface could be adapted to engage with a corresponding interlocking surface at the pipe.
  • the hose clamp further comprises observation cuts for observing the position of the hose within said hose clamp.
  • observation cuts could be strategically placed holes or cut outs in the hose-surrounding. They could for instance be placed at the bottom of the hose clamp allowing a person to observe when the hose has been pushed to the bottom of the pipe fitting.
  • the present invention further relates to a pipe adapted to be connected to a hose by inserting said pipe into said hose where the pipe further comprises clamp attachment means adapted to attach a hose clamp as described above prior to inserting said pipe into said hose and clamping said hose to said pipe.
  • a pipe where a hose clamp can be mounted at the pipe prior to connecting a hose to the pipe, is provided.
  • One advantage of the pipe is that the process of connecting the pipe to a hose is simplified and could be made much quicker compared to prior art.
  • the pipe could be made of plastic, metal or a combination of the two. Further, the same advantages as described above are achieved.
  • the clamp attachment means comprises at least one interlocking surface extending transversally outwardly from the outer surface of said pipe surface.
  • a hose clamp could easily be positioned at the pipe in a longitudinal direction being the direction along the hose and pipe fitting.
  • the transversally extending interlocking surface could be adapted to engage with a corresponding locking surface at the hose clamp and thereby automatically bring the hose clamp in the optimal clamping position. Further, the same advantages as described above are achieved.
  • the clamp attachment means comprises at least one supporting flange adapted to interlock with said pipe attachment means of said hose-clamp.
  • the pipe attachment means of a hose clamp could engage and interlock with a support flange at the pipe.
  • the supporting surface would support the hose clamp when it is positioned at the pipe and further when engaging with the pipe attachment means of the hose clamp preventing the hose clamp from getting out of position.
  • the present invention further relates to a system comprising at least one hose clamp as described above and at least one pipe.
  • a complete system comprising pipe and hose clamp is provided whereby the above advantages are achieved.
  • the system further comprises at least one outlet part.
  • the outlet part would allow water to flow inside the system to flow out of the system for instance through a water jet.
  • a pipe system for providing easy montage of a water jet in a whirlpool bath is provided.
  • the pipe system could easily be connected to a water circulation system using a hose, a hose clamp and a pipe as described above.
  • the pipe system could for instance be mounted at the sides or at the bottom of the whirlpool bath such that water would be let into the whirlpool bath through the outlet part of the pipe system.
  • the same advantages as described above are achieved.
  • the invention further relates to a method of connecting a hose to a pipe by inserting said pipe into said hose, said method comprises the step of attaching a hose clamp comprising pipe attachment means to said pipe prior to inserting said pipe into said hose.
  • the hose clamp further comprises clamping means and said method further comprises the step of clamping said hose to said pipe using clamping means.
  • Figure 1 illustrates an exploded view of a first embodiment of the present invention.
  • Figure 2 illustrates a perspective view of a first embodiment of the present invention.
  • Figure 3 illustrates a cross sectional view along line A-A of a first embodiment of the present invention.
  • Figure 4 illustrates a cross sectional view along line B-B of a first embodiment of the present invention.

  • Figure 5c illustrates a cross sectional view along line C-C of a hose clamp.
  • Figure 5b illustrates detail D of a hose clamp.
  • Figures 6a and 6b illustrate exploded views of a second embodiment of the present invention.
  • Figures 7a and 7b illustrate an exploded view and a perspective view of a jet system according to the present invention.
  • Figure 8 illustrates a cross sectional view of a third embodiment of the present invention.
  • Figure 9 illustrates a cross sectional view of a fourth embodiment of the present invention.
  • FIG. 1 illustrates an exploded view of a first embodiment of the present invention and illustrates a hose clamp (101 ), a pipe (102) and a hose (103).
  • the hose clamp comprises a hose-surrounding (104), clamping means and clamp positioning means.
  • the hose-surrounding is in this embodiment carried out as a cylinder, and the clamping means is carried out as two ribs (105) fixed at the top of the cylinder and extending inwardly towards the bottom of the cylinder.
  • the clamp positioning means are carried out as two support surfaces (107) that are placed at the bottom of the cylinder and are extending inwardly and transversally perpendicular to the cylinder surface.
  • the pipe comprises a pipe fitting (110) adapted to be entered in the hose and pipe positioning means comprising a supporting flange (108) placed at the bottom of the pipe fitting and two locking wings (109) extending outwards from and transversally perpendicular to the branch.
  • the supporting flange and the wings are adapted to be able to engage with the support surfaces (107) at the hose clamp, such that the hose clamp can be securely mounted to the pipe. This is achieved by adapting the support surfaces (107) and the locking wings such that the pipe fitting (110) can be inserted in the hose- surrounding and such that the locking surfaces would get in contact with the supporting flange. Thereafter the hose clamp can be rotated 90 degrees resulting in that the support surfaces would engage between the supporting flange and the locking wings.
  • Figure 3 illustrates a cross sectional view along line A-A in figure 2. It can be seen that the supporting surfaces (107) at the hose clamp engage between the supporting flanges (108) and the locking wings (109) at the pipe.
  • the locking wings comprise a locking knot (301) adapted to interlock with an interlocking hole (302) in the supporting surfaces through a snapping engagement. The result is that the hose clamp is further secured to the pipe.
  • Figure 4 illustrates a cross sectional view along line B-B in figure 3. This figure illustrates how the ribs (105) clamp the hose to the branch.
  • the ribs are in this embodiment resilient, so that it is possible to push the hose into the cylinder from the cylinder top, and the ribs would thereafter clamp the hose to the pipe fitting due to the resilient force.
  • the ends of the ribs could be embodied as sharp edges so that the ends would enter the hose jacket making the clamping of the hose more tightly. Further, this would also make it very difficult to pull the hose backwards thereby releasing the hose from the pipe branch.
  • by rotating the hose clamp 90 degrees such that supporting surfaces disengage with the supporting flange and the locking wings it is possible to dissemble the hose and pipe branch.
  • FIG. 5a illustrates a perspective view of another hose clamp (501 ) according to the present invention
  • figure 5b illustrates the same clamp seen from above.
  • the hose-surrounding is in this embodiment carried out as an open-ended band (502), and the clamping means comprises a first interlocking part (503) and a second interlocking part (504).
  • the open-ended band is embodied as an elastic plastic band that in its relaxed position substantially forms a cylinder.
  • the clamp positioning means is carried out as three interlocking surfaces (505) extending inwardly and transversally perpendicular at the bottom of the open-ended band.
  • the open-ended band further comprises an inner surface (506), where the inner circumference of the hose-surrounding band is smaller than the remaining parts of the hose- surrounding.
  • the hose clamp has further been provided with spikes (508) that are embodied as a part of the open-ended band. The spikes would enter the hose (not shown) when the hose-clamp is tightened causing an improved clamping of the hose.
  • the hose-clamp comprises monitoring openings (507) cut out of the open-ended band. The monitoring openings make it possible to monitor when the hose has been correctly placed at the pipe fitting for instance to monitor when the hose has been pushed to the end of the pipe fitting.
  • the second interlocking part (504) has an upper tongue (528) and a lower jaw (530) which cooperate with each other to form an elongated, open-ended cavity (532) there between.
  • the upper tongue (518) and the lower jaw (530) could optionally be somewhat thicker in the radial direction than the lower jaw (520) and the upper tongue (528) in order to maximize the clamping force when the interlocking parts (503, 504) are engaged as will be described hereinafter.
  • the thicker members, e.g. the upper tongue (518) and the lower jaw (530) serve to constrain the clamp in the radial direction, while the thinner members, e.g. the lower jaw (520) and the upper tongue (528), act as guides and supports for the thicker members.
  • Rows of teeth (524, 534) are formed on the lower surface of the upper tongue (518) and the upper surface of the lower jaw (530), respectively.
  • the teeth (524, 534) have any mating, interlocking shape, e.g. a generally triangular shape, and may have a directionality and/or shape that permits relative overriding in the locking direction and resists overriding in the unlocking direction; e.g. the teeth (524, 534) may point into the open-ended cavities (522, 532), respectively.
  • the teeth (524, 534) are formed of intersecting surfaces which define an acute angle relative to the direction of the locking movement and are inclined relative to the jaws (520, 530), respectively, so that the upper tongue (518) and the lower jaw (530) can slide relative to one another towards a locking position, but preventing movement in the opposite direction.
  • Finger grip pads (526, 536) are integrally formed on the interlocking parts (503, 504), respectively, opposite to the cavities (522, 532).
  • the upper tongue (518) of the first interlocking part (503) is sized and shaped to fit snugly into the open-ended cavity (532) of the second interlocking part (503) between the upper tongue (528) and the lower jaw (530).
  • the lower jaw (530) of the second interlocking part (504) is sized and shaped to fit snugly into the open-ended cavity (522) of the first interlocking part (503) between the upper tongue (518) and the lower jaw (520).
  • Figure 5c illustrates a cross sectional view along line C-C in figure 5b.
  • the first interlocking part (503) further comprises releasing grooves (509) where it is possible to insert a sharp-pointed/thin object such as a screwdriver after the first and second interlocking parts have engaged.
  • the interlocking parts can then be disengaged by twisting the sharp-pointed/thin object when it has been inserted into the releasing grooves causing the teeth (524, 534) to disengage.
  • the result is that the hose clamp could be dismounted whereby it is possible to disconnect the hose and the pipe.
  • FIG. 5d illustrates detail D in figure 5c.
  • the hose-surrounding (502) has further been provided with spikes (508) that are embodied as a part of the open-ended band and placed at one end of the inner surface (506).
