A holder for a cleaning pad or the like can include a base and one or more features to inhibit damage to a surface adjacent a surface being cleaned. For example, the holder can include a lip extending downwardly from an edge of the base along one or more sides to inhibit the pad from being coupled to the holder so that the pad extends beyond the edge of the base. The holder can also include one or more contacting features extending outwardly from the base on the side(s) including the lip to space the base and lip from the adjacent surface during use. The contacting features can be one or more wheels horizontally disposed on a top surface of the base.

A suction apparatus, a glass-wiping device and a run control method therefor. The suction apparatus comprises a suction cup unit (1). The suction cup unit (1) comprises an inner suction cup (11) and an outer suction cup (12). The inner suction cup (11) is arranged on the inside of the outer suction cup (12). A chamber on the inside of the inner suction cup (11) forms an inner negative pressure chamber (13) via vacuum suction. A chamber between the inner and outer suction cups (11 and 12) forms an outer negative pressure chamber (14) via vacuum suction. The outer negative pressure chamber (14) is connected to a vacuum detection unit. The vacuum detection unit comprises a distensible piece (20) and a distension-sensing piece (21). The distensible piece (20) is sealedly connected onto an opening on the top end of the outer negative pressure chamber (14). The distensible piece (20) has arranged thereon the distension-sensing piece (21). The glass-wiping device is provided with the suction apparatus, when in cases of failure of the outer suction cup (12) in the suction apparatus and of failure of the outer negative pressure chamber (14), the glass-wiping device will take measures immediately to prevent an increased number of small protrusions from entering the inner suction cup (11), thus preventing the phenomenon of the glass-wiping device falling off a wall from occurrence.

Die vorliegende Erfindung betrifft eine Vorrichtung zum Entfernen einer Eisschicht von einer Fläche, umfassend ein Halteelement (12) und ein an dem Halteelement (12) befestigtes Eisentfernungselement (14), wobei das Eisentfernungselement (14) ein Eisbrechelement (16) mit wenigstens einem Eisbrechzahn (22a, 22b, 22c) umfasst und der wenigstens eine Eisbrechzahn (22a, 22b, 22c) eine vordere Eisbrechkante (28a) an der Vorderseite (32a) des Eisbrechzahns (22a, 22b, 22c) aufweist. Der Eisbrechzahn (22a, 22b, 22c) weist an seiner Oberseite wenigstens eine Stufe (26b, 26c, 26d) auf, an deren Vorderseite (32b, 32c, 32d) eine weitere Eisbrechkante (28b, 28c, 28d) ausgebildet ist.
摘要:
The aim of the invention is to improve the manipulation of a suction nozzle, in particular for a portable hard-surface suction apparatus comprising a suction device, for cleaning hard surfaces. According to the invention, the suction nozzle has a suction opening connected to a suction channel, wherein the end of the suction channel facing away from the suction opening can be connected to the suction device. In order to achieve said aim, it is proposed that a joint is disposed or formed between the suction opening and the end of the suction channel so as to move the suction opening relative to the end of the suction channel and that a blocking device is provided for the force- and/or form-fitting blocking of the joint in at least one blocking position. The invention further relates to an improved hard-surface suction apparatus.

This invention relates to a rope access chair which, thanks to its geometry, provides unique comfort and safety conditions to people working in heights, due to its two arms wherein two ropes can be attached, thus increasing the chair's stability. The angle formed between the arms of the chair causes the equilibrium of forces to be achieved, providing the worker with stability in parallel to the work's vertical plane. This invention allows two ropes to be installed, thereby increasing stability, since the opening angle of the arms allows the worker to be balanced in the two ropes in parallel to the work's vertical plane, also ensuring that the space ahead is unobstructed so that he is able to work with his hands. The fact that the arms of the chair are ended with eyelets, allows descenders to be fixed thereto in order to perform lowering and raising operations. This invention is designed to be transported by a single man, thus providing greater work autonomy in what concerns the assembly operations of the ropes' systems intended for securing the workers, and its rigidity (which is similar to a common chair) exponentially enhances the workers' comfort.

An air-releasing valve for use in a suction apparatus and a suction robot having the air-releasing valve are provided. The air-releasing valve comprises an activation unit and an air-releasing valve retaining base (3). An air-releasing hole (11) in communication with a negative pressure chamber (18) of the suction apparatus is provided on the air-releasing valve retaining base (3). The activation unit is provided on the air-releasing valve retaining base (3) and is movable relative to the air-releasing valve retaining base (3) to open the air-releasing hole (11). A switch (4) is provided on the air-releasing valve retaining base (3). The activation unit opens the air-releasing hole (11) and triggers the switch (4) to shut off a vacuuming apparatus (14) of the suction apparatus simultaneously. The air-releasing valve is capable of rapidly releasing air from the suction apparatus and shutting off the vacuuming apparatus (14) in a timely manner.
