Description

The invention relates to a mobile device for mixing and/or conveying flowable building materials. Mobile devices for mixing and/or conveying flowable building materials, especially mortar, are typically used on construction sites to mix and/or convey materials such as cement, mortar, plaster, screed, tile adhesive, or similar substances. These devices are relatively heavy and often need to be moved or transported within the construction site. They are often equipped with casters to allow for pushing or pulling. Handles are provided to carry the device over obstacles. These handles are usually positioned at the same height, allowing for easy transport along a largely horizontal plane. Low obstacles can also be easily overcome. However, transporting the device on an incline or stairs is more difficult when the handles are at the same height. Furthermore, transporting the device by people of different heights can pose challenges. The invention is based on the objective of providing a mobile device for mixing and/or conveying flowable building materials that can be transported without difficulty both along a horizontal plane and along an inclined plane or stairs. This problem is solved by the device according to claim 1. According to the invention, a mobile device for mixing and/or conveying flowable building materials is provided, which has the following features: - a frame, - at least two mounting elements attached to the frame, and - at least one handle which can be detachably attached to one of the receiving elements by means of a fastening element, wherein - at least two mounting elements are attached to the frame at different heights, - the handle is provided for carrying and/or moving the device, and - the handle can be manually attached to and detached from the mounting element. The option to attach the handles at different heights facilitates the transport of the mobile device. The device can be easily transported along a horizontal plane if the handles on opposite sides are positioned at the same height. Along an incline or stairs, the device can be transported without difficulty if the handles on opposite sides are positioned at different heights. Since the handle can be manually attached to and detached from the mounting elements, its position can be easily adjusted. In particular, the frame has at least one, preferably two or four, vertical frame members, each of which has at least two receiving elements attached at different heights. Optionally, three or more receiving elements can be attached to the vertical frame member at different heights. For example, the mounting elements are permanently attached to the frame, in particular welded on. This contributes to the stability of the entire device. Preferably, the receiving elements each include at least one through-hole. The through-hole in the receiving element is suitable for receiving fasteners. Furthermore, the handle can have at least one, preferably two, through-holes at a proximal end. The through-hole in the handle is also suitable for receiving fasteners. In particular, the handle can have a notch at its proximal end, in the side walls of which two serial through-holes are formed. The notch with the two serial through-holes is suitable for coupling with the receiving element. For example, the proximal end of the handle and the receiving element are at least partially complementary to each other, with the through-holes of the handle and the receiving element sharing a common axis. This means that a single fastening element is sufficient to connect the handle to the receiving element. Preferably, the fastening element comprises a locking pin and a pivotable fastening part. The locking pin is designed to penetrate the through holes, while the The swiveling mounting part allows the locking pin to be secured. In particular, the fastening element is designed as a pipe cotter pin. The pipe cotter pin typically comprises, in addition to the locking pin, a curved double pin that is pivotally attached to the rear end of the locking pin. The two ends of the double pin are slightly offset at the rear end of the locking pin, so that the double pin is subjected to a preload. This preload causes the double pin to be pressed against the front end of the locking pin. The curved double pin is permanently attached to the locking pin and therefore cannot be lost. The pipe cotter pin remains functional even when dirty. The pipe cotter pin can be removed and tightened by the user without tools or other aids. Alternatively, the fastening element can be designed as a hinged bolt. The hinged bolt can also be easily loosened and tightened without tools. Furthermore, the fastener can have a locking pin and a spring clip. The locking pin and spring clip allow for easy attachment and removal of the handle. Alternatively, a screw connection could be used as a fastening element. Using a wing nut or similar fastener, the handle can be attached and detached without tools.
