Abstract

A fan blade comprising a mount supporting a plurality of superimposed fan blade segments arranged to slide relative to one another from a retracted storage configuration to an extended operative configuration.

Description

Ceiling fan

Technical field

The present invention relates to a kind of ceiling fan, relate more specifically to a kind of ceiling fan with scalable flabellum.

Background technique

The problem of many ceiling fans is when this ceiling fan does not use, and radial outstanding flabellum becomes disgusting dust-collector.Ceiling fan usually comprises lighting installation, and has proposed this lighting installation and comprise collapsible flabellum, and when not in this collapsible flabellum retraction lighting installation boundary, and radially outward launches thus runs as conventional flabellum in use.

The problem of this ceiling fan relates to will guarantee a kind of balanced arrangement, especially when flabellum moves between retracted position and running position.Another problem of this ceiling fan is that the length of flabellum is restricted in order to flabellum then can in retraction lighting installation boundary.This requires that each flabellum is nested usually, is positioned on the root of its adjacent flabellum by the front end of a flabellum, thus causes ugly the relaxing of flabellum.If make shorter in order to reduce overlapping needs by each flabellum, then this flabellum will lack aerodynamic force to drive enough air thus effective operation as fan.

These problems have drawn the present invention.

Summary of the invention

According to an aspect of the present invention, provide a kind of flabellum, described flabellum comprises assembling set, and this assembling set supports the flabellum section of multiple superposition, and this flabellum section is arranged to store form from retraction and slides relative to each other to stretching, extension operation form.

According to another aspect of the present invention, provide a kind of ceiling fan, this ceiling fan comprises electric motor, described electric motor is suitable for driving swivel plate, described swivel plate supports multiple flabellums of equi-spaced apart, described flabellum extends from described swivel plate radial direction, each flabellum comprises the root and end that are connected with trailing edge by leading edge, this root is suitable for being fixed to described plate, wherein each flabellum comprises multiple flabellum section, described multiple flabellum section is arranged to telescopic slide in another, thus described flabellum section can stretch by radially outward generally within the circumference of described plate and in operation form in retraction form.

Embodiment

Ceiling fan 10 shown in the drawings comprises the electric motor 11 on top, the room of hanging over.Electric motor 11 is connected to circular plate 12, and motor 11 is around vertical axis swivel plate 12 whereby.Plate 12 is suitable for the equally spaced flabellum assembly 20,21,22,23 of support four.Each flabellum assembly 20 to 23 comprises three flabellum sections 30,31,32, these three flabellum sections 30,31,32 can be slided from retracted position (Fig. 2) mutually to outside running position (Fig. 1), plate 12 boundary is positioned in this flabellum section of retracted position, give prominence to from plate 12 radially outward at this flabellum of outside running position section 30-32, thus be convenient to air flowing when plate 12 is rotated by electric motor 11.Be appreciated that electric motor 11 can be positioned on plate 12 or plate 12 times.

Each flabellum assembly 20-23 is positioned on the periphery of plate 12 by the assembling set 40 being fixed to plate 12.As shown in Figure 2 a, assembling set 40 around the periphery equi-spaced apart of plate, thus diametrically.

In this embodiment, flabellum comprises three flabellum sections, i.e. the first outer section 30, stage casing 31 and internal lobe end 32, and stage casing 31 telescopically is installed in outer section 30, and internal lobe end 32 again telescopically is installed in stage casing.

Each assembling set 40 comprises a pair supporting leg 41,42, and supporting leg 41,42 has outward extending flange 43,44, and flange 43,44 enables supporting leg be screwed to the surface of plate 12.Supporting leg 41,42 supports bridge 45, and bridge 45 defines the groove 46 of accommodation first siphonal lobe section 30.This groove limits a passage, and this passage permission leaf section 30 is smooth-going to be slidably fitted in groove 46.The supporting leg 41,42 of mounting assembly is also arranged so that (see Fig. 2 b) between groove slant 10 degree to 15 degree.This angle of groove gives flabellum established angle (otherwise being plane), thus when being positioned at expansion and running position, obtains desirable air flowing.

Leaf section 30,31,32 is all slided mutually, thus is positioned at stage casing 31 completely at retracted position (Fig. 2) end 32, and stage casing 31 is positioned at outer section 30 completely.Expanded position shown in Fig. 2, end 32 is given prominence to from stage casing 31 radially outward, and stage casing 31 is given prominence to from outer section of 30 radially outwards conversely.The scalable layout of 3 leaf sections allows each section of outwards motion, and forces the power of this outside motion to be the centrifugal force produced by electric motor 11 swivel plate 12.

Each is interconnected by chain 50 to flabellum assembly 21,22 or 23,24 diametrically, and chain 50 rotates around the chain gear 51 be positioned on the downside of each assembling set 40.This chain is also connected to the chain gear 52 being positioned at center, and chain gear 52 is connected to the helical spring 53 in housing 54 conversely.Chain 50 is connected to elongate rod 60 via adjustable linkage.

As shown in Figure 6, bar 60 is parallel to chain 50 and extends and the inner end being connected to siphonal lobe section 32.Bar 60 radially-inwardly pulls by the motion of chain 50, thus siphonal lobe section 32 is drawn in stage casing 31, until the stop member 63 on the inner end in the inner end contact stage casing 31 of leaf section 32.The further motion of bar 60 causes the inwardly displaced of stage casing 31 until it coordinates with the stop member 64 on the inner end of the first leaf section 30.Then all these leaf sections 30,31,32 to be drawn in below assembling set 40 by bar 60 thus are presented the complete retracted position of Fig. 2.

When the centrifugal force of ceiling fan 10 forces leaf section 30-32 outside, the motion of each leaf section causes the chain gear 51 under assembling set 40 to rotate thus spring 53 center of rotation chain gear 52 resisted conversely by chain drive-belt 50.When ceiling fan 10 slows down, helical spring 53 promotes center chain gear 52 rotating link chain 50 and leaf section 30-32 is retracted retracted position.By this way, the driving of chain gear and chain not only controls the outside motion of leaf section, and each leaf length of tape is not returned retracted position by spring 53 by the used time.In order to avoid chain 50 collides, different vertical planes arranges two center chain gears, higher chain gear drives flabellum assembly 20 and 21 and lower chain gear drives another to flabellum assembly 22 and 23.

Flabellum section 30-32 uses plastics molded thus limits leading edge and trailing edge.Leaf section 30-32 substantially flat and end segment 32 has crooked end.

Above-mentioned ceiling fan has many advantages relative to traditional ceiling fan with flexible flabellum.Because, so there is not risk of collision during telescopic process between flabellum in flabellum not pivotable from running position to retracted position.

In addition, leaf section is radial or launch in the vertical to mean that flabellum can be designed to have the length of increase, thus increases air flowing.In addition, the telescopic location of leaf section allows ceiling fan to present compact and form that is relative thin at retracted position, and this makes this ceiling fan (especially when it comprises lighting installation) on lighting installation, form other ceiling fan more attractive with scalable flabellum of ugly neck than flabellum when retracted position.

In claim subsequently and description above of the present invention, unless due to language performance or necessity hint and context needs difference, word " comprises " and such as " contains " or the variant of " comprising " is used in the meaning of inclusive, namely particularly point out the existence of described feature, but be not precluded within various embodiment of the present invention and there is other feature or add other feature.
