Description

"Suspension device".

  The present invention relates to a suspension device.

  Recently, fashion has come to decorate interiors

  foliage plants placed in the living rooms

  day of apartment buildings or office windows.

  For small plants, it is common to

  hanging on the ceiling, in a room, a cord at the end

  The purpose is to place the plant of small dimensions in a place where it is worthwhile However, if the plant is placed too high,

  it is necessary during each watering to depend on the cord of sus-

  board or use a stepladder.

  In view of the foregoing, the present invention provides

  a suspension device which makes it possible to modify

  denies the level or height of a hanging article, which may typically be the aforementioned small-leafed plant. To achieve the above-mentioned purpose, the suspension device according to the present invention comprises first a sufficiently large housing in which is mounted on an inner shaft, a drum to which is fixed the inner end i

  of a suspension cord, a restoring force being applied

  to the drum, in the winding direction of the cord of

  pension, using the elasticity of a spiral spring from this

  In fact, the suspension cord is in the absence of a load,

  rolled on the drum and housed in the case However, this

  This is not the only characteristic of the device

  According to the present invention, when

  pulling the suspension cord into the housing

  veloppe on a suitable length, against the elas-

  the spiral spring acting in the winding direction to suspend the article at the end of the cord, the suspended article descends to completely unwind the cord, and the weight of the suspended article generally exceeds the force of the spiral spring, and the article can not be kept suspended at the appropriate level. According to the second feature of the present invention, it overcomes this

  difficulty and, to that end, there is resistance

  against traction applied to the suspension cord, on

  the drum or on the suspension cord inside the wood

  in order to prevent the article from descending to the end of the race. The present invention is thus briefly described, but

  better understand it, as well as other goals and

  on reading the description of various modes of

  Preferred embodiments given below with reference to the accompanying drawings in which: Figure 1 is a longitudinal sectional view of a suspension device according to a first embodiment of the present invention; Figure 2 is a sectional view through II-II of Figure 1; Figure 3

  In the accompanying drawings; Figures 1 to 6 illustrate a first

  embodiment of the present invention.

  Referring now to Figures 1 and 2, the reference 1 designates a hollow housing composed of front shells 2 and rear 3 secured to each other In the center of the housing, a fairing 4 projecting from the inner face of the front shell 2 is mounted on the rear shell 3, the hollow housing 1 having an outer upper end secured to a suspension ring 5, a drum, indicated at 6, has an axial hole 7 through which it pivots on the axis 4 and a spring ral ral 9 t angularly exerting a restoring force in the direction indicated by the arrow B, is interposed between the bottom of a winding gor 8 formed in the outer periphery of the drum e the fixed axis 4, the spiral spring having its end the inner end fixed by engagement on the axis 4 while its outer end is fixed by engagement on a portion of the bottom of the groove 8 of the drum 6 A rotational resistance disc, in diqué 10, is mounted libr e to rotation, between the periphery

  outside of a boss 11 of the drum 6 and a perimeter shoulder

  12 formed, coaxially with the axis 4, on the surface

  2 of the front shell, a series of springs with angular rotation resistance blades, or antagonists 14, protruding elastically from the peripheral shoulder 12 inwards, mesh under pressure with corrugated teeth 13 of resistance in rotation or antagonists provided on the outer circumference of the disc 10 to provide a mechanism for resistance to rotation Locking pawls 17, constituted by a series of inclined leaf springs

  and protruding inwardly from an axial hole 16 of the annular disk

  tagonist 10, meshing with a ratchet wheel 15 formed in

  the outer periphery of the boss 11 whose teeth are not

  in one direction to form a ratchet mechanism

  the elements cooperate to let the disk spin

  10 when the drum 6 turns in the direction of the

  arrow A A suspension cord 18 whose inner end

  the upper part is fixed on a part of the groove 8 of the drum 6, is extracted through a cord hole 19 drilled in the lower part of the casing 1, the cord being wound in the same direction as the spiral spring 9 and its outer end being

  provided with a suspension member such as a hook 20.

  To use the suspension device having the structure described above is mounted on the lower surface of the ceiling using the suspension ring 5, as shown in Figure 3, and the hook is suspended 20 a pot to flowers or the like, the suspension cord 18 is extracted from the

  length by applying a determined pull,

  to adjust the suspension height.

  Indeed, when pulling on the suspension cord 18, the

  6 rotates in the direction of the arrow A, the ratchet wheel 15 meshes with the locking pawls 17 and thus the suspension cord 18 is extracted under the effect of the traction force applied to it which is greater to the sum of the total resistance force exerted between the teeth

  antagonists 13 of the rotational resistance mechanism

  in the outer periphery of the rotation resistance disk 10 and the opposing leaf springs 14 as well as

  by the banding force of the spiral spring 9 and, when the force

  this traction ceases to be exercised, the drum 6 rotates in the direction of the arrow B under the effect of the elastic spring return

  spiral 9, and the suspension cord 18 is wound in the wood.

  Tier 1 through the cord hole 19 Whereas at this time the ratchet mechanism provided between the rotation resistance disk 10 and the drum 6 is driven in the direction in which it does not resist rotation, the force elastic return

  spiral spring 9 does not come up against the strength of the machine.

  As a result, the suspension device makes it possible to stably suspend at an appropriate level an article to be suspended at

  having a weight between the spring force of the spring

  9 and the pulling force required to extract the

  In addition, if one makes sure to introduce a slight shift

  in the relative positions of each leaf spring antago-

  14 and cooperating teeth 13, it is possible to extract

  In addition, it is possible to

  incorporate in the mechanism of resistance to rotation a mechanism

  While in the mode of

  described above, the case 1 is suspended, it will be noted that it can be mounted in various ways, either directly

  as shown in Figure 5, either on the wall, the cord of

  pension 18 being extracted from the end of a support arm 21 protruding from a body as shown in FIG. 6,

  or in other forms As described above, the

  Suspension of suspension mentioned above may serve to suspend

  an article carrying a specified load at an appropriate level.

  Figures 7 to 14 of the accompanying drawings illustrate a second embodiment of the present invention.

  In Figures 7 and 8, the reference 31 designates a housing.

  In the center of the housing 31, is mounted fixed an axis 32 between a wall 31a and an outer wall 31b, and a drum 34, fixed

  by the bottom of its groove 34 has at the outer end of a res-

  spiral spring 33 itself fixed by its inner end on the fixed axis 32, journalled on the fixed axis 32 In the groove 34 a of the drum 34 is wound in the winding direction of the spring

  spiral 33, a suspension cord 35 whose integral end

  is attached to a part of the drum and this cord is

  by the elastic return force of the spiral spring 33

  the outer end of the cord passes through a load control mechanism 36, first guided by a guide wall 50a and then by a guide wall 50b, and it exits through a cord hole 37 drilled in the case 31 An organ of

  suspension such as hook 38 is attached to the end of the cord.

  The load control mechanism 36 includes a first fixed pin 39 projecting near the location where the cord leaves the drum 34, a second fixed pin 40 located

  adjacent to the cord hole 37, a rotational adjustment member

  41 located between the two fixed pins 39 and 40 and rotatably mounted on the outer wall 31c of the casing 31, and two movable pins 43 mounted between the element 41 and a shaft 42

  itself mounted in the partition 31 to the shaft 42 is cyan-shaped

  lindrique and journalled in an axial hole of the partition 31 a; the outer end of the rotary adjusting element 41 is of cylindrical shape and journalled in an axial hole of the outer wall 31c, and small meshing studs 45, radially projecting and equidistant on the inner end of the element 41 engages, in each angular position, in receiving receptacles 46 Men, és in the inner end surface of the axial hole of the outer wall 31 c A coil wound 47, interposed between the shaft 42 and the partition 31 a, does not elastically urge the rotary adjusting element 41 in a direction opposite to the arrow C, so that the pins 45 engage in the receiving recesses 46 to oppose

  rotation of the rotary adjusting element 41 and that, when

  that the element 41 is forced in the direction of the arrow C by

  mdntant the elastic force of the coiled spring 47, the nipples 4

  are cleared receptor recesses 46, to turn

  screwdriver to turn element 41 at will.

  49 refers to a suspension ring projecting 1 '

  interior of the upper part of the case 31.

  To use the suspension device having the above-mentioned structure, it is mounted on the bottom surface of the bottom plate, by means of the suspension ring 49, as shown in FIG. 9, and the hook 35 is suspended. a flower pot a or the like The load adjusting mechanism 36 is set according to the load applied by the suspended article

  to the suspension cord 35 so that it, when

  extracted on the desired length, remains stable in

  the corresponding position, which makes it possible to vary

the suspension height.

  Indeed, when pulling on the suspension cord 35, it unwinds the drum passing through the adjustment mechanism of the load 36 However, when the angular position of the rotary adjusting ele- ment 41 is changed, the arrangement relative to the first fixed spindle 39, the second fixed spindle of the first fixed spindle 39, the second fixed spindle

  and two movable pins 43,44 is modified,

  shown in Figures 10 to 12, and the portion of the suspension cord 35 between the two fixed pins 30 and is displaced from a position in which the cord does not contact the movable pins 43, 44, as shown in Fig. 10, to a position where the bead has varying deflection angles between the fixed, movable, movable pins 39, 40, 43, 44 to vary the slip resistance as shown in Figs. 11 and 12, the suspension cord length extracted from

  stable because there is a balance between the load

  by the suspended article a and the friction force opposed to the slip existing between the fixed pins 39,40 and movable 43, 44 of the load control mechanism 36 and the suspension cord 35, on the one hand, and the spring return force

spiral 33, on the other hand.

  Therefore, the length of the suspension cord can be reduced.

  35 by abolishing the charge applied by the above-mentioned article

  hung so as to eliminate the sliding friction resistance introduced by the fixed pins 39, 40 and movable 43, 44, which causes the cord to wind on the drum 44 under the effect of return of the spiral spring 33 Quoique in the

  embodiment described above the housing 31, or of the spherical type

  It should be noted that it is also possible to use various other forms such as the direct-ceiling type shown in FIG. 13, or the rosette type illustrated in FIG. 14. In a variant, the end of FIG. suspension cord 35 can be fixed to the ceiling or the like and serve to suspend the body of the housing 31 As described above, the suspension device in question can be used to suspend at the desired level of articles applying various loads.

  Therefore, the suspension device according to this

  vention is very useful for suspending items at level 3 that can be mod Xfier to vary the presentation or to suspend foliage plants that it is desirable to be able to sink to water, Although it has been described only certain preferred embodiments of the present invention, it is clear that one can adopt various modifications and variants without departing from the scope of the invention,
