Embodiment Construction

[0037] figure 1 A schematic cross-sectional view of a telescopic pole 10 according to a first embodiment of the invention is shown. The telescopic rod 10 is provided as a connecting element between a handle, handle, guide rail or operating lever on the one hand and a manually guideable device or device system on the other hand.

[0038] The telescoping rod 10 has an outer tube 12 , an inner tube 14 , a retaining clip 16 and a lock nut 18 . The inner tube 14 is displaceable inside the outer tube 12 along a common longitudinal axis. Instead of the inner tube 14 , the telescopic rod 10 can have, for example, a solid or at least partly solid rod that can be displaced within the outer tube 12 along a common longitudinal axis. The advantage of the inner tube 14 is that connecting rods or cables and / or cables for mechanical force transmission can be arranged in the inner tube 14 and thus inside the telescopic rod 10 .

[0039] Optionally, the inner tube 14 is also rotatable inside...

Abstract

The invention relates to a telescopic rod (10), in particular for a handheld device (40) or device system. The telescopic rod (10) has an outer tube (12) and an inner tube (14) or a rod. The inner tube (14) or the rod can be moved in the outer tube (12) along a common longitudinal axis. The telescopic rod (10) further comprises a retaining clip (16) with a sleeve (20) for receiving an end region of the outer tube (12) and a clamping ring (22) for surrounding the inner tube (14) or rod. The telescopic rod (10) additionally has a union nut (18) which is screwed or can be screwed onto the clamping ring (22) of the retaining clip (16) such that the clamping ring (22) exerts a force onto the surrounded region of the inner tube (14) or rod, and thus the inner tube (14) or the rod is fixed or canbe fixed to the retaining clip (16). The end region of the outer tube (12) and the sleeve (20) are connected or can be connected by means of a latching mechanism or mutually complementary elements (26, 48).

Description

technical field [0001] The invention relates to a telescopic rod, in particular for a manually guided device or device system. Furthermore, the invention relates to a guide device for a manually guideable device or device system. Furthermore, the invention relates to a manually guided device or device system having at least one telescopic rod. For example, a telescopic rod is provided as a connecting element between the handle or handle and the manually guideable device or device system. Background technique [0002] Manually guided devices with telescopic rods are found in numerous applications. Gardening equipment such as manual or motor-driven trimmers, lawn trimmers, hedge trimmers, lawn trimmers or lawn mowers often have telescopic poles. In this case, the telescopic rod enables adaptation to the height of the user and / or to the geometry of the area to be processed. [0003] Known telescopic rods are mechanically in most cases relatively complex in design and have a...
