Detailed description of the invention

As it is shown in figure 1, elevator car handle of the present invention, including skeleton 1, polyurethane cladding shell 2, skeleton 1 is along its length Extending, skeleton 1 is wrapped up in the inner by polyurethane cladding shell 2 along its length；

The cross section of skeleton 1 be U-shaped (as in figure 2 it is shown) or Ω type (i.e. the two ends of U-shaped form outside kink 13, As it is shown on figure 3), to form an inner fovea part；The opening 12 of skeleton 1 is forward；

Skeleton 1 is formed by the method such as extruding metal or sheet metal bending, it is possible to use plastic or other material molding is to alleviate weight；

Polyurethane cladding shell 2 is connected by polyurethane material is fixing with the skeleton 1 after molding by the way of pouring；The present invention adopts By the mode poured, it is possible to make the connection between skeleton 1 and polyurethane cladding shell 2 tightr；Compare traditional outside tubing The mode of one layer of clad of set, it connects more firm, should not damage and deform.

The skeleton 1 of the present invention forms an inner fovea part, and this inner fovea part forms the structure of a similar cavity, and this cavity can make handrail There is more space at center, and after skeleton 1 is coated with by polyurethane cladding shell 2, there is more polyurethane material inside such that it is able to Improve buffer capacity.

The kink 13 of Ω type skeleton 1 both wings of the present invention can be greatly improved the rigidity of skeleton itself, to ensure that handrail has foot Enough rigidity.

Clash into usually from the shock in transverse horizontal direction due to elevator car handle, the impact force in other directions all without very big, The direction i.e. clashed into is relatively fixed, and the present invention is directed to this feature, uses U-shaped or the framing structure of Ω type and opening forward, Horizontal cross rum point position can be made to fill more polyurethane material, and less polyurethane material is then filled at upper and lower and back, Both decrease the use of polyurethane material, improve the effect of crashproof buffering the most to greatest extent.

The depth of section of polyurethane cladding shell 2 is between 50mm to 200mm；Too small depth of section due to shock surface too small and Do not have effective crashproof cushioning effect, and depth of section can weaken significantly if greater than 200mm, the integral rigidity of handrail, Lean on handrail time bigger deformation can occur, be susceptible to handrail loosen etc. phenomenon.

The cross-sectional width of polyurethane cladding shell 2 is not less than 20mm；Cross-sectional width directly determines the filling thickness of polyurethane material, If cross-sectional width is too small, the polyurethane material thickness of filling is also the most thinning, have impact on crashproof effect；

In view of the appearance of handrail, the depth-width ratio of polyurethane cladding shell 2, about at 5:1 to 3:1, does not the most affect handrail In the effect that car is overall, wide or long meeting makes it unlike handrail.

The liftoff setting height(from bottom) of elevator car handle of the present invention is between 700mm to 900mm；Due to crashproof object predominantly doctor The sick bed of institute or go-cart etc., too high setting height(from bottom) can make rum point that region beyond handrail occurs, and actual does not has crashproof effect Really.

For some shippings or the elevator of other occasions, it is also possible to consider to install a handrail under first handrail again, double hold up Hands can more efficiently play the effect of crashproof buffering, i.e. car handrail can install single (as shown in Figure 5) or double (as Shown in Fig. 6).

The inner fovea part of skeleton 1 can be distributed multiple skeletal supports 5 along its length；Owing to polyurethane cladding shell 2 passes through Pouring mode molding, skeletal supports 5 is prevented from the framework deformation caused because polyurethane shrinks, i.e. at skeleton 1 by poly-ammonia During ester cladding shell 2 cladding, skeleton 1 will not be towards the Wall deformation of inner fovea part, and the buffering after polyurethane is coated with is imitated Fruit does not weakens because skeleton subsides.

As shown in Figure 4, the back 11 of skeleton 1 can be with welded nut, it is also possible to directly at back 11 tapping 6 of skeleton 1, As shown in Figure 4；The back 11 of skeleton 1 is connected by screw thread 6 is fixing with armrest mounting seat 4, and real by armrest mounting seat 4 Now it is connected with the fixing of lift car；

The density of the polyurethane material that polyurethane cladding shell 2 is used is between 0.09 to 0.12kg/cm3；In this range The buffering effect optimum sick bed of polyurethane or the shock of go-cart, self quality of low density polyurethane material is sparse, is running into During shock, deflection can substantially increase, and the material that the effect of absorption energy is relatively compact is poor, and anti-collision effect also can reduce；Right In the object that the quality such as sick bed or go-cart is bigger, its kinetic energy also can strain greatly mutually；Low density polyurethane material absorbs the energy of energy Power is relatively low, does not fully absorbs at impact kinetic energy, and polyurethane material has been compacted, it is impossible to effectively play the effect of crashproof buffering； Density can preferably absorb impact in the polyurethane material of more than 0.09kg/cm3, plays the effect of crashproof buffering；And poly-ammonia When ester material density is too high, owing to material is the finest and close, the bounce after buffering can strengthen accordingly, is unfavorable for handrail on the contrary Buffering effect.

During forming polyurethane cladding shell 2 by the way of pouring, other compositions can be added in polyurethane material It is made to produce extra effect；In polyurethane material, add antibacterial, handrail can be made to have antibacterial effect, much cleaner, More environmentally friendly, it is especially suitable for the public arenas such as market, subway, hospital；Dyed particles is added in polyurethane material, thus it is possible to vary The color of polyurethane material, makes handrail outward appearance more bright-coloured, improves the qualitative perception that handrail is overall.

The two ends of polyurethane cladding shell 2 are provided with end socket or end cap 3, have the most both played effect attractive in appearance, and also can protect simultaneously The end of polyurethane does not exposes, and protects polyurethane material, increases the service life.
