Sling according to embodiment of the present invention is illustrated in Fig. 1 to Figure 17, and is designated as 10 usually.

Sling comprises four basic elements of character, that is, and and main body 12, connector 14, spring 16 and backboard 18.All these parts can be made by plastics or metal.Also may form main body 12, connector 14 and the backboard 18 of plastics, and form the spring 16 of metal.

Main body 12 has antetheca 20, relative rear wall 22 and base 24, thereby limits the satchel (pocket) 26 with open upper end.Two

holes

28,30 are formed on the antetheca 20 of main body 12.With of the rear wall 22 vertical extensions of integrally formed two the general

cylindrical shape extensions

32,34 of main body 12 from main body 12.

Pass extension

32,34 and

form hole

36,38 respectively, rear wall 22 is also passed in hole 36,38.Hole 28 in the antetheca 20 is aimed at the hole 38 of passing extension 34 and rear wall 22, and the hole 30 in the antetheca 20 is aimed at the hole 36 of passing extension 32 and rear wall 22.By this layout, rope can pass hole 28 and be inserted in the satchel 26 and pass hole 38; Rope can pass hole 30 and be inserted in the satchel 26 and pass hole 36.

Especially in Figure 15 as can be seen, extension 34 has the head 34b of 34a of cylinder body portion and expansion.Extension 32 has identical structure.

Main body 12 and the 3rd extension 40 are integrally formed, and the 3rd extension 40 vertically extends from rear wall 22.When from top or below when observing, the 3rd extension 40 is the general shape of letter " T ".Still can see, on the base 24 of satchel 26, be formed with upwardly extending jut 42, to close with a vertical termination of spring 16.

Turn to connector 14 now, the head 46 that connector 14 has main part 44 and enlarges slightly, and elongated groove 48 is formed in the main part 44.Jut 50 is formed on the closing end place of groove 48, to close with another vertical termination of spring 16.Two

holes

52,54 are formed in the main part 44 of connector 14.

When assembled, in satchel 24, admit at least a portion of connector 14, make that connector 14 can be in satchel 24 with respect to main body 12 up and down (promptly, shown in the double-ended arrow F-F among Figure 16) move, this double-ended arrow F-F is perpendicular to the longitudinal axis D-D of the extension 34 of main body 12 and the longitudinal axis E-E of extension 32.When assembled, spring 16 makes base 24 biasings of connector 14 away from satchel 26.Be illustrated as separate part here though it will be understood by those skilled in the art that spring 16, alternately use and connector 14 or the bias unit integrally formed, to realize bias capability with the base 24 of satchel 26.

In the process that connector 14 moves in satchel 26, the active porosity that passes sling 10 changes, make when connector 14 space maximum during near the base 24 of satchel 26, when connector 14 from the base 24 of satchel 26 space minimum farthest the time.By this layout, if rope passes the

hole

28,38 of main body 12 and the hole 52 of connector, so when connector 14 when the base 24 of satchel 26 fully moves (" disengagement form "), rope can slide with respect to the

hole

28,38 and the plug hole 38 of main body 12, and when connector 14 during fully away from the base 24 (" joint form ") of satchel 26, rope with locked to be prevented from sliding motion with respect to sling 10.This is identical with the situation in hole 54 that rope passes the

hole

30,36 of main body 12 and connector 14.It should be noted, because the bias of spring 16, so connector 14 is towards engaging the form biasing.

As for backboard 18, also with reference to Figure 18, backboard 18 comprises two

outer arms

56,58, and

outer arm

56,58 has end difference (stepped portion) 60,62 separately.Two outer arms 56 all are resilient, and therefore can be pulled away from or push away the central longitudinal axis H-H of backboard 18 slightly.Central area along backboard 18 is formed with elongated slotted eye 64.Vertical end 64a of elastic tongue piece 66 and slotted eye 64 is integrally formed, and extends towards another vertical end 64b of slotted eye 64, but does not contact with another vertical 64b that holds of slotted eye 64.The free vertically end of tongue piece 66 is from vertical end 64b one distance of slotted eye 64, and this distance equals or slightly greater than the thickness t (seeing Figure 15) of the extension 40 of main body 12.Two

end differences

68,70 are formed at vertical end 64b place of slotted eye 64.

Figure 19 to Figure 23 B shows the step that sling 10 is assembled to article 72, and wherein Figure 22 B is the side view of Figure 22 A, and Figure 23 B is the side view of Figure 23 A.Article 72 can be fabrics of a part that forms the wall of support bag or knapsack or luggage.

For sling 10 is assembled to article 72, at first in satchel 26, admit spring 16, then connector 14 is assembled in the satchel 26, make an end of spring 16 engage with the jut 50 of connector 14, and the other end engages with the jut 42 of the base 24 of main body 12, so that connector 14 is away from base 24 biasings of main body 12.As shown in figure 20, the head 46 of connector 14 extends above the satchel 26 of main body 12, thereby can be operated by the user.On article 72, form three

holes

74,76,78, as shown in figure 21.The shape in

hole

74,76 is circular, and the shape in hole 78 is rectangles.Hole 74,76,78 is determined size and dimension to receive

extension

32,34,40 respectively.

Therefore, when the main body 12 of sling was installed on the article 72, backboard 18 moved along the direction of being represented by arrow K among Figure 22 A and Figure 22 B with respect to main body 12, and this direction is substantially perpendicular to the longitudinal axis of

extension

32,34.

In this motion process, slide on the tongue piece 66 of the free end of extension 40 in the slotted eye 64 of backboard 18 and along tongue piece 66, because the elasticity of

arm

56,58, the end difference 62 of arm 58 slips into the space between the head of expansion of the rear wall 22 of main body 12 and extension 32, and the end difference 60 of arm 56 slips into the space between the head 34a of expansion of the rear wall 22 of main body 12 and extension 34.Therefore,

arm

56,58 engages with

extension

32,34 in the mode of buckle.Joint between the head that enlarges separately of the

end difference

60,62 of

arm

56,58 and

extension

34,32 prevents that

arm

56,58 is along being separated with

extension

34,32 by the direction shown in the arrow P among Figure 23 B.

When being assembled validly, shown in Figure 23 A and Figure 23 B, arm 58 engages with the outer surface of extension 32, and arm 56 engages with the outer surface of extension 34, and because the elasticity of tongue piece 66, extension 40 passes vertical end 64b place that slotted eye 64 was received and was positioned at slotted eye 64.When being in this position, the free end of tongue piece 66 in abutting connection with or contiguous extension 40, thereby prevent backboard 18 along separating with main body 12 by the direction shown in the arrow R, the direction shown in the arrow K is opposite among the direction shown in this arrow R and Figure 22 A and Figure 22 B.

In addition, vertical end of extension 40 also is positioned on the

end difference

68,70 at vertical end 64b place of slotted eye 64, and this helps also to prevent that backboard 18 is along being separated with main body 12 by the direction shown in the arrow P among Figure 23 B.

When by appropriate assembling, two

ropes

80,82 can pass sling 10, shown in Figure 24 A to 25C.Shown in Figure 24 A to Figure 24 C, when the bias force that overcomes spring 16 when connector 14 moved to and throws off form, rope 80,82 can slide with respect to sling 10.On the other hand, shown in Figure 25 A to Figure 25 C, when moving to the joint form under the bias force effect of connector 14 at spring 16, rope all is prevented from sliding with respect to sling 10.

The embodiment that the present invention thus can realize only is shown above it should be understood that, and under the situation that does not break away from spirit of the present invention, can carries out various modifications and/or change embodiment.

In addition, for for simplicity, the of the present invention various features of describing with single embodiment also can provide separately or provide in any suitable sub-portfolio here.
