The specific embodiment

Below in conjunction with drawings and Examples, the utility model is elaborated.

Consult Fig. 1 and Fig. 3, the first preferred embodiment of the utility model hollow plastic railing, this hollow plastic railing extends along an axis L, and comprises a lower rod member 10, upper lever 20, joint 30 and a coating layer 40.

This lower rod member 10 is made hollow rod shape with plastic cement material, and have one be straight shaft-like flat segments 11 and one along this axis L be arranged at the moulding section 12 of these flat segments 11 1 sides, bottom that is arranged at these flat segments 11 1 sides in contrast to this moulding section 12 13, one in contrast to this bottom 13 and be arranged at the cohesive end 14 of these moulding section 12 1 sides, the inserting column 15 and the lower endoporus 16 being extended towards this inserting column 15 by this bottom 13 that are protruded along this axis L by this cohesive end 14 in contrast to this flat segments 11, the length L 1 of this lower rod member 10 is no more than 30 inches.In the present embodiment, this flat segments 11 is square perpendicular to the cross section of this axis L, this moulding section 12 is rounded perpendicular to the cross section of this axis L, and this lower endoporus 16 has one corresponding to this flat segments 11 and is square hole section 161 and class's hole section 162 that is communicated to this inserting column 15 along this axis L by this square hole section 161 and is circular hole perpendicular to the cross section of this axis L of square hole perpendicular to the cross section of this axis L.

This upper lever 20 is connected in this lower rod member 10 1 sides along this axis L, and make circular cone hollow rod shape with plastic cement material, and there is a top 21 along this axis L in contrast to this bottom 13, socket end 22 and a upper endoporus 23 being extended towards this top 21 by this socket end 22 along this axis L in contrast to this top 21, the outer peripheral face of this upper lever 20 is expanded in the time that stretch on these socket end 22 edges gradually by this top 21, and on this, endoporus 23 is also taper hole shape to outer peripheral face that should upper lever 20, and there is a shrinking section 231 corresponding to this socket end 22, the inserting column 15 of this lower rod member 10 is plugged in this shrinking section 231, coordinate ginseng Fig. 4, this shrinking section 231 has an inner ring surface 232 around this axis L and several gum box 233 that arranges and supply to store adhesive agent along this inner ring surface 232, the length L 2 of this upper lever 20 is no more than 30 inches.

Coordinate ginseng Fig. 2, this joint 30 is made with plastic cement material, be installed on this lower rod member 10 and to should bottom 13, and there is a plug member 31 in the square hole section 161 that is fixedly arranged on this lower endoporus 16 and one and be connected in this plug member 31 and protrude from the tenon post 32 of these lower endoporus 16 outsides along this axis L.This plug member 31 perpendicular to the cross sectional shape of this axis L corresponding to the square hole section 161 of this lower endoporus 16 perpendicular to the cross sectional shape of this axis L and be hollow square, and this plug member 31 is the hollow tube-shape of unidirectional opening, and there is an end 311 in contrast to this tenon post 32, outside wall surface of being extended towards this tenon post 32 by this end 311 312, the internal face 313 in contrast to this outside wall surface 312 and a several shrinkage joint 314 of extending and be communicated with this outside wall surface 312, this internal face 313 by this end 311 towards this tenon post 32.This tenon post 32 is hollow circular perpendicular to the cross section of this axis L.

This coating layer 40 is extended to the outer peripheral face of this upper lever 20 by the outer peripheral face of this lower rod member 10.

Again as shown in Figure 3, when the inserting column 15 of this lower rod member 10 is inserted in the shrinking section 231 of upper endoporus 23 of this upper lever 20, and utilize the effect of the adhesive agent storing in described gum box 233, can make this lower rod member 10 and this upper lever 20 be fixed together (seeing Fig. 4), recycle the outer peripheral face that this coating layer 40 is coated on this lower rod member 10 and this upper lever 20, can make the outward appearance of this railing present overall shape.

In the time that railing will be installed, respectively be drilled with a hole 110 in the corresponding position of a stair tread 100 and a handrail 200 in advance, 210 (as shown in Fig. 3 imaginary lines), and the tenon post 32 of this joint 30 is inserted in the hole 110 of this stair tread 100, again the lower endoporus 16 of the lower rod member 10 of affixed all-in-one-piece railing is sheathed on to this plug member 31 outsides, and utilize the setting at described shrinkage joint 314, can make this plug member 31 there is the ability that produces elastic deformation with respect to this axis L, and can to produce packing affixed with the bottom of this lower rod member 10 13, and make the bottom 13 of this railing produce location with respect to this stair tread 100, in the time that also intercalation is positioned the hole 210 of this handrail 200 on the top 21 of this railing, can make railing firmly be installed between stair tread 100 and handrail 200.

Effect of hollow plastic railing of the present utility model can be summarized as follows again:

One, whole the railing being made up of this lower rod member 10, this upper lever 20 and this joint 30 is all to make with plastic cement material, can not expend the forest reserves, and this lower rod member 10, this upper lever 20 and this joint 30 be all hollow structure, and this railing overall weight is lighter.

Two, this railing is made up of this lower rod member 10, this upper lever 20 and this joint 30, and the length L 2 that the length L 1 of utilizing this upper lever 10 is no more than 30 inches and this lower rod member 20 is no more than the effect of 30 inches, so being used for making the die length of this lower rod member 10, this upper lever 20 is less than for making US6,494, the mould of the railing of 438 Patent Cases, it is also comparatively easy that plastic material when ejection formation will riddle the each position of die cavity completely, the material plumpness at this each position of hollow plastic railing is comparatively even, may reduce the fraction defective of product.

Therefore, hollow plastic railing of the present utility model can solve now parapeted problem, and has the fact that effect is promoted.

For another example shown in Fig. 5 and Fig. 6, the second preferred embodiment and first preferred embodiment of the utility model hollow plastic railing are roughly the same, also comprise a lower rod member 10 ', upper lever 20 ', joint 30 ' and one and coat the coating layer 40 ' of this lower rod member 10 ' and this upper lever 20 ' outer peripheral face.

The difference of this second preferred embodiment and the first preferred embodiment is the setting position of this moulding section, that is to say, this lower rod member 10 ' is to be straight shaft-like flat segments 11 ' as main, and moulding section is not set, there is a bottom 13 ', a cohesive end 14 ' in contrast to this bottom 13 ', an inserting column 15 ' being protruded along this axis L by this cohesive end 14 ' and a lower endoporus 16 ' being extended towards this inserting column 15 ' by this bottom 13 ' yet.The length L 1 of this lower rod member 10 ' is no more than 30 inches.

This upper lever 20 ' has a moulding section 220 ' that is the shaft-like extension 210 ' of circular cone and and is arranged at this extension 210 ' one side, this top 21 ' is arranged at a side of this extension 210 ' in contrast to this moulding section 220 ', this socket end 22 ' is arranged at a side of this moulding section 220 ' in contrast to this extension 210 ', on this, endoporus 23 ' has a shrinking section 231 ' corresponding to this socket end 22 ' and this moulding section 220 ', this shrinking section 231 ' also has several confessions and stores the gum box 233 ' of adhesive agent, the length L 2 of this upper lever 20 ' is no more than 30 inches.

Utilize this inserting column 15 ' to be plugged in this shrinking section 231 ' inside, also can make this lower rod member 10 ' and this upper lever 20 ' reach affixed object, and effect that this second preferred embodiment can produce is also identical with the first preferred embodiment.
