Abstract
A hanger bar for supporting a recessed light fixture is attachable to ceiling joists or a T--bar grid of a drop down ceiling. First and second bars of the hanger bar slide and telescope. First and second spring clips are detachably coupled to the brackets at the ends of the first and second bars, respectively. Each of the first and second clips has a pair of downwardly extending arms bent inwardly toward one another, a first leg extending from a first arm, a second leg extending from a second arm, and an outwardly-extending foot on the second leg. The spring clips snap on to the T-bar grid. Each bracket includes a nail that is angled away from the hanger bar and downward so that the nail head is below the level of the hanger bar. The angled nails enable easy hammer strikes to attach the hanger bar to ceiling joists without accidental hammer blows to the hanger bar. The bracket may be discrete from the hanger bar but attached via tox clinching or a tab pass-through attachment.

The specific embodiment
Fig. 1 is the perspective view of preferred embodiment that is used for the suspension rod 10,12 of built-in lighting light fixture 14.Described suspension rod combines built-in lighting light fixture 14 and the ceiling with ceiling joist 16,18.Light fixture comprises cylinder blanket or the iron sheet cover 20 that is supported on the rectangular frame 22.Be arranged on equally on the framework 22 to be terminal box 24 exchange input electric power and for being installed in the conduit 26,28 that lamp socket in the iron sheet cover 20 and decoration (not shown) provide electric power with being used to receive.
By the suspension rod 10,12 of preferred embodiment, light fixture 14 is supported on its both sides.For guaranteeing that built-in lighting light fixture 14 is fixed on and has wooden ceiling joist for example on 16,18 the ceiling, suspension rod 10,12 preferably is stapled on the corresponding ceiling joist.Therefore, prepare for example nail of 30,32 at each end of suspension rod 10,12.As shown in Figure 1, electrician or installation personnel can use hammer 34 that nail 30,32 hammers are gone into joist.Spring clip 36,38 is arranged on the end of each suspension rod equally, is used for further guaranteeing that suspension rod is fixed on the ceiling joist.Particularly each clip 36,28 comprises the pin with a perforate 40; Nail, screw or other fixture (not shown)s can be fixed on nail below the corresponding ceiling joist by perforate 40.The special geometrical construction and the structure of relevant clip 36,38 are described in greater detail below.
Fig. 2 is mounted in the perspective view of the built-in lighting light fixture 14 on the drop-down ceiling T shape bar 44,46. Clip 36,38 and 42 comprises the 4th clip (not shown), is stinging to clamp on the T of corresponding horizontal shape bar.In this case, owing to need not the nail fixed derrick to horizontal T shape bar 44,46, suspension rod also need not to be tufted into the somewhere of joist.
Comparison diagram 1 and Fig. 2 can see, suspension rod 10,12nd is general, and they can be fixed to above and/or under the ceiling joist on the pull-type ceiling component.For example, the horizontal T shape bar 44 and 46 of Fig. 2. Clip 36,38 is mainly used in fixed derrick to the pull-down ceiling component.But as shown in Figure 1, each clip has respectively and can be fixed in outward extending pin below the corresponding ceiling joist with ailing or other modes.
Consider the structure of a preferred embodiment suspension rod now, and with reference to figure 3-6, suspension rod 10 for example shown in Figure 1 has preferably slidably and interconnected bar 60 and 62.Bar 62 has flanging or the crimping 64,66 that forms a guide groove, and another bar that matches 60 just can slide in guide groove.In this way, finished the structure of slip pole device.This makes that the user can be according to the needs of actual conditions, and according to the interval as the 44 and 46 horizontal T shape bars of Fig. 2, or the length of whole lever apparatus is regulated at the interval of ceiling joist 16,18.Fig. 7 shows the contraction structure of suspension rod 10, and Fig. 8 shows the stretched out structure of same suspension rod 10.By this way, the suspension rod adjustable length is to the needed length of on-the-spot installation personnel.
Get back to Fig. 3-6, nail or other fixtures 30,32 extend through corresponding holder device or ear 70,76.In typical preferred embodiment, nail 30,32 makes nail head (Fig. 3) upwards with respect to the length direction of bar 60,62, and outwards (Fig. 4 and 6) departs from the formation certain angle.By giving the space of hammering nail, avoid using hammer head accident to be hammered onto the suspension rod that metal sheet is made, the angle that nail or fixture form has made things convenient for the structure workman, electrician or installation personnel.Because nail hammers into joist along the axis that is not parallel to the suspension rod major axis, the angle that nail forms also causes corresponding bar to fixedly secure more on corresponding joist.Because nail-shaped is angled, the weight that is pressed in the lighting on the suspension rod is not easy nail is withdrawed from.Yet, be noted that when lighting is fixed on the T shape bar 44,46 of pull-down ceiling, just need not the fixture 30,32 of nail or other types, for example, as shown in Figure 2.
When nail 30,32 is used as fixture, be installed in the appropriate location of support 70,76 usually by friction.Nail can comprise a circle of leaving a bit of distance of flat ailhead, and the spacing collar of similar flange makes nail hammer into the ceiling joist with predetermined distance.When hammering during to the flat ailhead of nail, the top of nail or tip pass completely through suspension rod and enter the ceiling joist.Can select to have circlet shape rib near the nail top, make nail catch wooden joists better.
The rear side of display pole 62 in Fig. 5 has a selectable fold or sawtooth 208 to improve the rigidity and the intensity of bar 62.Sawtooth 206 (not shown)s that sawtooth or projection 204 hinder coupling on the bar 60 come off in full extension to avoid bar 60,62.
Fig. 9 is the birds-eye perspective according to suspension rod 10 of the present invention.The perspective view of Figure 10 shows clip and bracket component in more detail.Figure 11 is the bottom perspective view of suspension rod 10, and Figure 12 is the detailed view of clip and bracket component.Each support 70,76 has first ear part 72,78 and arm portion 74,80.Each arm 74,80 is determined theoretical planes, and forms an obtuse angle (greater than 90 degree) with respect to the theoretical planes of part 72,78 being determined by each first ear.Can the most obviously see this obtuse angle in corresponding Fig. 4 and 6 upward view and the vertical view.Arm 74,80 comprises the nail hole of being passed respectively by nail 30,32 110,112.Because each nail 30,32 passes respectively with respect to first ear part 72,78 is formed the arm 74,80 of an angle, and described ear is parallel to every bar 60,62 usually to part, this obtuse angle causes each nail 30,32 to depart from bar 60,62 equally forming an angle.That is to say that the other end is most advanced and sophisticated because each nail end of 30,32 has a flat ailhead, flat ailhead is in than nail tip from the farther position of bar 60,62.Equally, in Fig. 4 and 6, can be clear that.
In view of Figure 10, the spring clip 38 that has a U-shaped top 82 usually removably is connected to arm 80.Clip 38 preferably by high-intensity spring steel manufacturing, can play the effect of vising or clamping, and clip bends to the U-shaped of compound camber line.Clamping action makes clip 38 firmly bite and hold to the T section of T shape bar 44,46.
Refer to Figure 10 once more, two planes that are in two ends of suspension rod are uneven.Especially, front panel 88 is determined a plane that comprises protuberance 84 and 86 surfaces usually, and this plane is generally perpendicular to the length direction of bar 60,62.Another plane that comprises arm 80 is not parallel, angled with the plane that comprises front panel 88.Because nail 32 perforate 112 of passing is arranged on the surface of arm 80 of certain angle, nail has an angle equally.Therefore, this angle of nail 32 can make flat ailhead depart from bar 62.Owing to there is bigger space between nail and bar, nail forms this angle guarantor makes installation personnel use hammer directly to knock nail, has avoided unexpected and has knocked and action bar 62 in the same way.This and form sharp contrast with the nail of suspension rod parallel orientation.
Further, nail 32 shown in Figure 10 is preferably formed as certain angle makes flat ailhead towards down, perhaps follows closely point towards last.If first and second bars 60,62 drop on theoretical planes, horizontal plane, the nail that forms certain angle so makes flat ailhead be lower than this plane and its ailhead is in or be higher than horizontal plane.Nail 32 downward certain angles make installation personnel when installation is in position, the crown or be higher than the whole built-in lighting light fixture of position, the crown, knock ailhead with hammer from following his present position easilier.If nail is parallel with suspension rod or be positioned at horizontal plane, stand in the installer's nail on the striking head squarely that is lower than the nail position.
Figure 13 is the device after clip 38 is moved down by end user or on-the-spot installation personnel among Figure 10.In order remove clip 38, the three spring arms 150 to place the top of clip 38.Between the main body of the 3rd arm 150 and clip 38, determine an interval 152.The 3rd arm 150 can be selected to comprise and can help to connect the pin 154 of clip 38 to support 76.Support 76 can comprise commissure 160, for example the perforate on horizontal shelf 162.In the embodiment of Figure 13, by the 3rd arm 150 of slide clamp 38 forward, make protrusion 164 embed the opening 160 of holder devices, clip 38 just may be buckled into the fixed position of shelf 162.Selectable, opening 160 is perforates of a recess rather than a standard-sized sheet.Clip 38 is fixed on the support 76 by tight friction or pressure contact.
Because the 3rd arm 150 is spring arms, this arm is used for clip 38 is locked in suspension rod 10 position that requires.On-the-spot installation personnel or electrician can remove clip 38 as required.In order to remove clip, protrusion 164 is broken away from from the opening or the recess 160 of ear handle assembly, clip is that available pliers is pulled out from suspension rod.
What note is that the first arm 140 and second arm 142 are spring arms.They are preferably made by this way: they curve inwardly towards another arm mutually at 170,172 places, zone.Leg 144,146 outwards is crimped onto and forms a neck or relative narrow 174 in the clip.This neck 174 stressed opening at that time, when being pushed downwards to horizontal T shape bar when clip, the T shape bar 46 among Fig. 2 for example, neck 174 is stressed to be opened and the elasticity of spring arm 140 and 142 makes arm clamp T shape bar 46 downwards, so just suspension rod 10 can be securely fixed on the T shape bar 46, thereby built-in lighting light fixture 14 is mounted on the horizontal T shape bar.Arm 140,142 tips that outwards curl form at a gulp subly 176, make installation personnel more easily aim at and push clip to T shape bar.Often, the head term of installation personnel is positioned at the below of T shape grid, and like this, the operation that clip is connected to T shape grid is just above head term, and also with regard to the horizontal line of sight top, operation will be with sensation, thus big opening 176 easy the work of installation personnel.If be certain reason, perhaps because the spatial constraints of ceiling region does not need clip 36,38, installation personnel can take off them rapidly from suspension rod 10,12 simply.
In the above-described embodiments, when two bars were contracted to minimum entire length, the no support end of a bar can not slip over another shaft bar end.As shown in Figure 9, this situation be because the ear that the crimping 64,66 of bar 62 has knocked another bar 60 62, and can not move again, just limited the contracted length of whole suspension rod.On the other hand, Figure 16 shows the optional embodiment of suspension rod 10 ', and it has an improved ear the part of conduct at bar end support.In the embodiment of Figure 16, ear has transition face 200 to 72 ', makes ear extremely in parallel the copline that moves apart with suspension rod 10 '.Transition face 200 among Figure 16, spaced rods 60 ' and ear handle a little, for the crimping 64 ', 66 ' of another bar 62 ' no support end provides the space, with the ear that slips over bar 60 ' 72 '.This is called as " passing through " feature sometimes in industry.
Requiring among the optional embodiment of Figure 16-18 provides other modes, and does not adopt " passing through " feature, just, prevents that the no support end of suspension rod 62 ' from slipping over the support 70 ' of another suspension rod 60 '.Therefore, showing selectable stop 202 in Figure 17 and 18, herein, is the little bonding jumper of a picture finger sample, has stopped that bar 60 ' no support tip forward slides.When bar 60 ', 62 ' shrank, stop 202 can prevent that the no support end of stopping bar 60 ' passes support 76 ' like this.When bar outwards extends, a selectable protruding part or sawtooth 204 are set on bar 60 ', second protruding part or sawtooth (not shown) are set as stop on bar 62 '.Because when bar outwards extended, protruding part stoped mutually in case stopping bar 60 ' skids off guide groove and throws off, thus the mutual moving range between limit rod two bars.
Figure 19 is the perspective view of the optional embodiment of suspension rod 300.As in other embodiments, suspension rod 300 has straight-bar 326 parts that slip into second straight-bar 324, and wherein second straight-bar 324 has folded edge, to form a guide groove.When two bars 326,324 were slidingly connected as shown in FIG., suspension rod 300 was extensile on length by its contractile function.Two ends of suspension rod 300 are axisymmetric.An end of suspension rod 300 be a pentagonal ear part 304, be connected to an end of straight-bar 326.
Ear is the preferably polygonal flat material of part 304, and can separate and separate with straight-bar 326.Ear is connected to part 304 end of straight-bar 326 by joint 328.The structure and the function of this joint illustrate in greater detail below.Ear part 304 drop on the parallel plane theoretical planes of determining by straight-bar 326 in.
Ear is the end edge of part 304 curved edges, and transition changes arm 306 over to.The plane that comprises arm 306 does not form a right angle with respect to the plane of directly being determined by bar 326, describes as the vertical view of Figure 21.In other words, angle A is not 90 degree but is at a slight tilt the more accurate obtuse angle of saying so.312 1 guiding of nail are given at this inclination angle, make its axostylus axostyle and ailhead 314 depart from bar 324,326 and extend.As mentioning and as described in Fig. 1, this makes installation personnel the front, the easier ailhead 314 that is hammered onto of electrician or carpenter is avoided knocking bar 324,326 unexpectedly and is damaged the bar of being made by metal sheet usually.In a preferred embodiment, nail 312 as shown in figure 21 departs from suspension rod 324,326 about 10.2 degree.
Figure 22 is the side view of the same end of the suspension rod 300 described of Figure 21.In this preferred embodiment, nail 312 departs from the angle that horizontal plane forms about 10 degree downwards.Because the installation of suspension rod 300 occurs in and be higher than the installation personnel shoulder position when he stand on the ladder, nail 312 angulations make ailhead 314 be in the position that easier hammer knocks.Therefore, installation personnel can be easier with hammer knock the surface towards under ailhead 314.When needs are installed a lot of built-in lighting light fixture, the installation of each light fixture needs a pair of suspension rod, ailhead 314 has been saved a large amount of labours of installation personnel and time towards the angle of installation personnel, and further having reduced wrong hammering to the undesigned infringement of suspension rod, this infringement had not only been lost time and but also waste material.From nail diameter, the interval of ceiling joist, suspension rod size, the research experience of ergonomics angle is seen, this installed position provides clearance space in ceiling, has found that it is preferable that nail 312 among Figure 22 departs from the angles that bar 324,326 forms about 10.2 degree ± 3 degree.In Figure 22, found that nail 312 is preferable from horizontal level downward bias from the angle of about 10 degree ± 3 degree equally.
Figure 20 is the independent perspective view of another end of suspension rod 300 shown in Figure 19, wherein, ear the optional embodiment of part 304 ' in, shelf 322 ' is a plane, the width of pressing protuberance 308 ' launches.By contrast, Figure 19 middle ear are spent warpages, the nail point of partial restriction nail 312 ' to the preferred shelf of part with 90.The ear that is provided with the crooked shelf of 90 degree in Figure 19 is among the embodiment of part, and the rigidity and the anti-deformation nature of nail 312 ' bending metallic plate have on every side all obtained reinforcement.The bending of in the metallic plate 90 degree is similar to is locating to place a firm angle bar near nail 312 '.Because such rigidity, nail in the suspension rod installation process, any when being tufted into the ceiling joist do not hit ailhead 314 ' and hits ear and will seldom can make the wrong hammering of part 304 ' ear part or shelf distortion.If protuberance or shelf are bent or twist, suspension rod can not nestle up the ceiling joist and meet at right angles and installed.
Except not bending shelf 322 ', the ear of Figure 20 is identical part with ear shown in Figure 19 part.In Figure 20, support 302 ' is connected to the end of guide groove bar 324 by joint 328 '.Support 302 ' comprises the ear that is polygonal shape part 304 ', and this ear has an arm portion 306 with respect to bar 324,326 bendings out of square to part 304 '.Owing to be provided with another end, ear is part 304 ' the independently parts that separate with guide groove bar 324, and fixed thereon by joint 328 ' subsequently.
Having the benefit that a support and its parts and suspension rod separately make is to have reduced the complexity of cost and manufacturing.Suspension rod and support preferably all are by the metal sheets manufacturing.As shown in drawings, for example, be provided with several folding lines, the plane, non-perpendicular angle etc., the manufacturing expense of support is very high and comprise complicated punching press, punches and the metal forming step.Make support with same metallic plate making the bar part and aggravated the complexity of manufacturing and the quantity of manufacturing step, and produce waste material.Therefore, support and bar are separately made, and connect the two portions together at the later stage of making again, and this is very favorable.
