Description

Technical Field

[0001] The invention relates to a blower and / or extractor, in particular a leaf blower and / or leaf extractor, which can be carried by a user. Summary of the invention

[0002] The object of the present invention is to provide a user-portable air blower and / or leaf extractor, in particular in the form of a leaf blower and / or leaf extractor, which has improved properties.

[0003] This object is achieved by the subject matter of the independent claims. Preferred embodiments are the subject matter of the dependent claims.

[0004] According to the present invention, the user-carryable blower and / or suction device has a blower and / or suction pipe, which is used to pass through and guide the blowing and / or suction flow along the pipe axis of the blowing and / or suction pipe. "Along" can be understood synonymously with "parallel" in this context. In particular, the blowing and / or suction pipe extends longitudinally along the pipe axis. The user-carryable blower and / or suction device can be a leaf blower and / or leaf suction device. The user-carryable blower and / or suction device has a blower for generating a blowing and / or suction flow, which can be guided through the blowing and / or suction pipe. The user-carryable blower and / or suction device also has a housing. The housing carries the blowing and / or suction pipe. In particular, the housing also carries the blower. The housing has a particularly integral handle. In addition, the housing has two side sections, particularly on the outside. The handle is particularly at least or only partially extended longitudinally in a reference plane containing the tube axis of the blower and / or the extractor. The reference plane can include the tube axis. The reference plane extends between the side sections. In particular, the longitudinal extension direction of the tube axis and the handle opens the reference plane. The side sections can then be placed on both sides of the reference plane. The handle is particularly extended longitudinally along its longitudinal extension direction. In particular, the two side sections can be transverse to the tube axis, especially just opposite the handle, especially in the reference plane. The blower and / or the extractor that can be carried by the user also has a first fastening device in the form of a first bearing eyelet and a second fastening device in the form of a second bearing eyelet. The first fastening device and the second fastening device are arranged at the same side section of the housing. Here, the first fastening device and the second fastening device are particularly arranged perpendicular to the tube axis and are arranged relative to each other at intervals along the tube axis. In particular, only the spacing between the fastening devices extends and / or is measured along the tube axis, wherein these fastening devices can be at different distances from the reference plane. In other words: the first fastening device is arranged at one of the side sections, and the second fastening device is arranged at a distance from the first fastening device along the tube axis at the same relevant side section. In particular, the blower and / or the extractor can be carried by the user together by means of the first fastening device and by means of the second fastening device. The bearing force for the user to carry the blower and / or the extractor can be introduced into the housing by means of two fastening devices. Here, the bearing force can be advantageously introduced into different parts of the housing by means of two fastening devices. Correspondingly, it is feasible that the fastening devices are respectively designed only for a part of the transmission bearing force. The bearing force corresponds to the weight of the blower and / or the extractor that can be carried by the user in terms of value. By arranging the fastening devices at a distance relative to each other along the tube axis, it is therefore advantageously possible to provide a free space between the two fastening devices, which free space can be used, for example, for the user's hand that the user grasps the handle.Since the two fastening devices are arranged laterally on the housing near the handle, the blower and / or suction device carried by the user can be automatically aligned due to gravity in such a way that the handle is tilted away from the user. This can facilitate the user's grip.

[0005] In particular, a user-carryable blower and / or suction device is carried by the user only when the blower and / or suction device is actually carried by the user. In contrast, if the blower and / or suction device is designed to be carried by the user but is not currently (yet) carried by the user, the blower and / or suction device is only capable of being carried by the user and is not (yet) carried by the user. In particular, when the blower and / or suction device is carried by the user, the reference plane is inclined relative to the direction of gravity.

[0006] In the embodiment of the invention, the handle is arranged along the tube axis between the first fastening device and the second fastening device. In particular, the first fastening device and, alternatively or additionally, the second fastening device are located in the region of the transition between the relevant side section and the handle of the housing. Advantageously, the handle can then be arranged in the region adjacent to the free space between the two fastening devices, so that the handle can be grasped by the user's hand through the free space, particularly without hindrance.

[0007] In another embodiment of the present invention, the first fastening device and the housing are constructed in one piece or two pieces and / or are connected to each other. As an alternative or additional solution, the second fastening device and the housing are constructed in one piece or two pieces and / or are connected to each other. The one-piece connection can advantageously save the complicated assembly of the corresponding fastening device at the housing. In contrast, the two-piece connection of the corresponding fastening device and the housing can achieve the replaceability of the relevant fastening device, especially in the event of damage. If the corresponding fastening device is connected to the housing in one piece, the relevant fastening device can be integrally formed at the housing. If the corresponding fastening device is connected to the housing in two pieces, the relevant fastening device can be screwed to the housing.

[0008] In another embodiment of the present invention, the housing is constructed in multiple parts. Here, the first fastening device and the second fastening device are arranged on a common housing part of the housing or on different housing parts of the housing.

[0009] In a further embodiment of the invention, the housing has an air-permeable ventilation grille housing part. In this case, the blower device is arranged, in particular along the tube axis, between the ventilation grille housing part and the blowing and / or suction pipe in order to convey air for the blowing and / or suction flow through the ventilation grille housing part. In this case, the first fastening device is arranged, in particular, integrally formed on the ventilation grille housing part.

[0010] In a further embodiment of the invention, the blower device can be electrically driven in order to generate the blowing and / or suction air flow.

[0011] In another embodiment of the present invention, the blower and / or extractor that can be carried by the user has a replaceable battery pack carried by the housing, which is used to supply the blower with electric drive energy. The battery pack can be a storage battery pack. The battery pack is arranged, in particular, accommodated opposite the handle and at a distance from the pipe axis. This can result in a particularly advantageous positioning of the overall center of mass of the blower and / or extractor that can be carried by the user.

[0012] In another embodiment of the present invention, the user-carryable blower and / or suction device has a belt element. The belt element has a first belt end and a second belt end. The first belt end can be arranged opposite the second belt end, especially along the tube axis. Here, the first belt end is coupled to the first fastening device and the second belt end is coupled to the second fastening device, especially releasably.

[0013] In another design of the present invention, the belt element has a connecting device, which is arranged between the first belt end and the second belt end, especially along the tube axis. The connecting device can be arranged between the two belt ends of the belt element centrally or eccentrically. The belt element can be at least partially elastically and can be longitudinally extended and / or can be constructed in an essentially inelastic manner. The position of the connecting device between the two belt ends can be adjusted and locked, especially in order to determine the inclination of the tube axis of the blower-and / or the absorber carried by the user relative to the direction of gravity. As an alternative or additional solution, at least one belt section of the belt element between one of the two belt ends and the connecting device can be configured with a variable length, especially with a length that can be set without longitudinal extension. As an alternative or additional solution, at least one or just one belt section in the belt section can be configured elastically and can be longitudinally extended. The connecting device is configured to connect the belt element to a carrying device carried by the user or that can be carried by the user, especially in the form of a carrying belt. In particular, the carrying device is not a component of the blower-and / or the absorber that can be carried by the user. In particular, the connecting device has a belt loop for hanging a hook of a carrying device. If the user-carryable blowing and / or suction device is carried by the user by means of a carrying device carried by the user, the connecting device of the belt element can be arranged in the direction of gravity, in particular substantially just above the total center of mass of the user-carrying blowing and / or suction device.

[0014] In another embodiment of the present invention, the total center of mass of the blower and / or the suction device that can be carried by the user is arranged between the first fastening device and the second fastening device along the tube axis. As an alternative or additional solution, when the blower and / or the suction device that can be carried by the user is carried by the user together with the first fastening device and with the second fastening device, the first fastening device and the second fastening device are respectively arranged perpendicular to the tube axis with respect to the direction of gravity above the total center of mass of the blower and / or the suction device that can be carried by the user. This promotes the above-mentioned automatic alignment of the blower and / or the suction device that is carried by the user, which is determined by gravity.

[0015] Further advantages and features of the invention are apparent from the claims and from the following description of preferred exemplary embodiments of the invention, which are shown with reference to the drawings. In this context, identical reference numerals denote identical or similar or functionally identical components. BRIEF DESCRIPTION OF THE DRAWINGS
