摘要： The hose, which is particularly adapted for use with an electrically-driven vacuum cleaning apparatus, comprises a substantially air-tight, flexible tube which is pneumatically coupled between the vacuum pump and the suction head. The suction hose comprises one or more elongated strips which is or are helically wound into tubular form. In a pair of parallelly placed strips, the strip margin of the first strip is secured to an adjacent margin of the second strip at adjoining convolutions of the strips. Electrical conductors are carried by the strips within helically extending cavities formed at the edges or margins of each of the strips and are a portion of that means which electrically couples the cleaning brush to the electrical power supply.

摘要： Apparatus (42, 72) is used to fill a hose (36) with water (12), from which a secondary source of power is derived, and simultaneously to expel air from the hose while connected to the vacuum side of a pump (20) without loss of the prime in the pump. The apparatus comprises a housing (44, 74) submergeable in the water and having a pair of chambers (46, 48 & 76, 78) respectively having inlets (58, 80) and outlets (64, 86), with the inlets being open to the water and the outlets being coupled respectively to the pump and to the hose. Impellers (54, 100 & 56, 102) respectively in their chambers are coupled together by a shaft (52, 98) in which a first of the impellers (54, 100) is driven by a second of the impellers (56, 102) when water is drawn by the pump past the second of the impellers. In one embodiment, when the hose is used as a suction conduct, an elbow conduit (110) can be slid from a first position where water purges air from the hose to a second position where the hose is used to clean debris from the swimming pool. In another embodiment, a hose end is first coupled to the pump's pressure side (24) to expel air from the hose and thereafter, without removing the hose end from the water, the hose end is coupled to the pump's vacuum side (22) when the hose is used to vacuum the pool.

摘要： One or more electric conductors (36, 236) in a flexible hose (10, 210) are protected from tensile and compressive forces exerted on or by the hose by providing an enclosure (32, 232) for the conductor(s) whose radial dimension (46, 246) provides a path for movement of the conductor(s) that is greater than any movement thereon exerted on or by the hose which might otherwise harm or break the conductor(s).

摘要： A fitting (10) secures a vacuum hose (20) to a wand or tank of a vacuum cleaner. The hose is swivelably and pneumatically sealed within the fitting through use of a sealing surface (18) on the fitting in engagement with a flexible lip (28) at the end portion (24) of the vacuum hose. A ring (30) engageable with the fitting compresses the end portion in order to bias the flexible lip into engagement with the sealing surface. The electrical terminations including slip rings (144) are used to terminate a hose (120) with electrical conductors therein to cooperating electrical connections.

摘要： A flexible hose having resistance to radial crush is formed from a bonded and interlocked helically wound rod or strip of plastic co-extrusion. The co-extruded profile of the strip is defined by a pair of matable rib components which are joined by a web. The rib components are bonded, sealed and interlocked together at adjoining convolutions of the profile not only to form the hose but also to form a composite rib integrated into the hose for resisting radial crushing and axially directed deformation forces exerted on the hose. The composite rib is formed from a material having a hardness which is greater than that of at least a part of the web for rendering the rib with a relatively stiff bend resistance characteristic and the web with a relatively soft and flexible characteristic. The web itself may be a co-extrusion of two materials placed in series, or in parallel as a laminate, or a combination thereof. If a laminate, one of its materials may be the same as that of the rib but much thinner so as to provide a larger surface area for greater bonding or adhesion among the several parts of the extruded profile. Different materials, especially in a laminate, enable the hose to be tailored for specific uses and environments which come into contact with either or both the inside and outside of the hose.
摘要翻译： 具有抵抗径向挤压的柔性软管由粘合和互锁的螺旋缠绕的棒或塑料共挤条形成。 条带的共挤出型材由一对可通过纤维网连接的可配对的肋部件限定。 肋部件在轮廓的相邻卷圈处被接合，密封和互锁在一起，不仅可以形成软管，而且还可以形成集成到软管中的复合肋，以抵抗施加在软管上的径向破碎和轴向引导的变形力。 复合肋由具有大于网状物的至少一部分的硬度的材料形成，以使得具有相对刚性的弯曲阻力特性的肋具有相对柔软和柔性的特性。 网状物本身可以是两种材料的共挤出物，它们作为层叠体或它们的组合串联或并联放置。 如果层压材料中的一种材料可以与肋的材料相同，但是更薄，以便在挤出型材的几个部分之间提供更大的表面积用于更大的粘合或粘合。 不同的材料，特别是在层压板中，使得软管可以针对与软管的内部和外部接触的特定用途和环境进行定制。
