A coupling part for a fluid coupling device, especially a hose coupling, which has a looking device switchable between two positions. The locking device has locking elements mounted on a base body, and a socket-shaped actuating element that interacts with the locking elements. The coupling part is switchable between a retaining and releasing positions by an axial releasing movement of the actuating element. In the retaining position, the locking elements hold the counterpart of the coupling, e.g. a hose stem, to prevents it from being pulled out and, in the releasing position, the locking elements release the same in order to disengage the coupling. The actuating element can be moved from the retaining position into a locking position, prohibiting a releasing movement, by rotating the actuating element in a limited manner around the longitudinal axis of the coupling. As a result, the coupling is prevented from being unintentionally disengaged.

Shears ( ) preferably constructed as hand-held garden or pruning shears or secateurs has two shear elements ( ) pivotable against one another about a pivot axis ( ) and which have engaging portions ( ) for mutual cutting engagement and which in the opened state of the shears form a shear mouth widening from the pivot axis becoming smaller on closing the shears. According to the invention rubber-like holding means ( ) are provided for retaining cutting material introduced into the shear opening during the cutting process and which only act up to the completion of the cutting process, i.e. until the cutting material is cut through, so that the cut cutting material is released by the shears without it being necessary to open the latter again for this purpose.

A portable or travelling transporting device for winding material usable as a hose truck has a frame ( ), to which are fitted a travelling mechanism ( ) with ground wheels ( ) for moving on a ground surface, as well as a hose winding drum. The ground wheels ( ) rotating on moving the hose truck can be brought into driving connection with the winding drum by means of a force transfer means ( ) constructed as a flat gear. A slip clutch ( ) located in the force transfer path ensures that during the advance of the hose truck a laid out hose can be wound onto the winding drum with a limited winding force appropriate for troublefree, compact winding on.

A pond insert more particularly intended for insertion in a garden pond is described and which has at least one electromotively driven pump ( ) The pump has an inlet connection and two intercommunicating outlet connections ( ), whereof one is preferably oriented horizontally and one vertically. The pump can be fixed in a basket-like container ( ), which can be filled with a weighting material such as gravel or the like for improving the stability of the pond insert.

In a sprinkling apparatus constructed as a square sprinkler, which has a straight nozzle row with a plurality of nozzles and directionally adjustable nozzle axes, it is possible to tilt the nozzle axes of single nozzles collectively relative to one another. A preferred embodiment has a fan-like sprinkling pattern, the jets of the fan being symmetrically or asymmetrically brought together or moved apart. The fan edges can be adjusted independently of one another.

Method for adjusting the sprinkling pattern of a sprinkling apparatus

A sprinkling apparatus constructed as a square sprinkler has a nozzle arrangement with a straight row of nozzles, whereof each has a nozzle inlet connected by a nozzle duct to a nozzle outlet. At least in a portion between the nozzle inlet and nozzle outlet, the nozzles are constructed as rubber-like water guidance ducts, which are disconnectable by a force action transversely to the water flow direction. For the disconnection of individual nozzles clamping sliders are provided and are displaceable transversely to the water flow direction against the rubber-like nozzles and in the case of a displacement in each case disconnect or release again a nozzle. This permits a very variable adjustment of the sprinkling pattern.

On a sleeve for a gardening tool, for example a quick coupling (12), surface parts of a flexible, soft and grip-promoting material (24) are provided in differing individual sections. These are applied in a two-component injection molding method and may also comprise special bump rims (27). By a differing color design and alternating exposure of the surface of the two composite materials of base body (17) and additional element (24) lettering, marking or configuring the surface may be achieved.

A hose connector with gripping elements (18) pressing a hose (14) on a socket (15) uses a two-part sleeve (24). The two-part sleeve includes a screw piece (25) and an extension sleeve connected to the screw piece by a rotary connection and the two-part sleeve surrounds and supports the hose for a significant portion beyond the clamping area of the gripping elements (18). This inner sleeve (32) also has the funnel-shaped, conical actuating surface (33) for the pressing of the gripping elements.

With a limited separating spacing immediately upstream of a mowing implement rotating in a horizontal plane, a lawnmower has an upward extraction implement rotating in the same direction as the advance direction about a horizontal transverse axis and which is located in a common casing, but in a separate casing chamber. The upward extraction implement is disengagingly driven by means of a gear by the drive motor of the mowing implement and is essentially located between the front wheels, which are vertically adjustable for the joint setting of the working height of the two implements. Thus, it is possible to in each case separately and also jointly and simultaneously work with the two implements, so that numerous use possibilities exist.

A flush sprinkler has a sprinkler unit raisable and lowerable in hydraulic manner in a shaft and, several nozzle units, which, as required, can be switched into a sprinkling state with an upper nozzle selecting handle and whose nozzle jets can be modified independently by a jet spreading member adjustable with an associated jet adjusting handle. There are also rings for varying a spray spreading angle as a function of size and position. The handles are raisable and lowerable with the sprinkler unit and therefore easily accessible. For cleaning the bearing of the sprinkler unit, an automatically valve-controlled flushing device is provided. For the reliable draining of the sprinkler, a drain valve is provided directly in the water flow and its body is clipped into a valve bore of the shaft.

An electric supply device for the cordless operation of electrical appliances has a holder fixed to the electrical appliance for detachably locking and substantially exposing a mounting support of a storage unit. For electrical contact connection, approximately in the plane of a countersunk bearing surface, the storage unit has flat, rigid contacting contacts, with which are associated corresponding countercontacting contacts in the vicinity of the associated counterbearing surface of the holder. The contacting contacts are proximate to a hinge axis formed by a projecting hinged cam and a cam pocket between the storage unit and the holder, so that a favorable leverage is obtained. For detachable locking, two separately, but simultaneously, operable locks are provided in the vicinity of the other end of the storage unit, in which the holder is substantially embedded.

In a drive mechanism for a transportable sprinkler or the like, a hydraulic motor has a reduction gear, whose gear or gear wheels are outside the water distribution system in a separate gear chamber and are therefore dry. However, the gear chamber is so integrated into the casing of the hydraulic motor, that it is adjacent to a reversing chamber used for water distribution purposes and in which is located a reversing valve of a reversing device for the alternating reversing of the hydraulic motor in both rotation directions. The hydraulic motor is drive-connected by means of a driven pinion to a support and in the drive connection is arranged a self-engaging safety clutch. Between the reversing chamber and a rotor chamber connected axially thereto and to the gear chamber is provided a pressure-dependently operating bypass water distribution system with simple flap valves. Thus, high operational reliability with extremely compact construction of the hydraulic motor is obtained.

In a sprinkler (1), the water distributors (10) for supplying the spray nozzles (13, 14, 15) is formed by a separate main channel (15) inserted in a spray nozzle casing (2) and having relatively small flow cross-sections compared with the casing cross-sections, which is also constructed in one piece with the spray nozzles (13, 14, 15), so that the spray nozzle casing (2) does not have to be used for water distribution purposes and can instead merely serve as a support casing. Of the spray nozzles arranged in a row, those which are located at the end of the row can be individually manually disconnected with separate check valves (36), so that in simple manner it is possible to adjust the width of the exiting water curtain within certain limits.
