The specific embodiment

With reference to the accompanying drawings embodiments of the invention are illustrated.

Fig. 1 is the vertical view of first embodiment of Slipcover of chair leg of the present invention.Fig. 2 is the side view of this Slipcover of chair leg.Fig. 3 is the upward view of this Slipcover of chair leg, and Fig. 5 is the cutaway view of solid lubrication parts among Fig. 3.In addition, Figure 12 is the stereogram of this Slipcover of chair leg user mode.

Slipcover of chair leg 1 of the present invention is the Slipcover of chair leg that adds cover in the end of chair legs 2 (with reference to Figure 12), and it is made of cladding parts 3 that coats chair legs 2 ends and the solid lubrication parts 4 that are sewn on these cladding parts 3 outsides.

Describe these inscapes below successively in detail.

Cladding parts 3 is used to coat the end of chair legs 2.This coating member 3, its top form the bag shape of opening, sew up wheel rubber 5 on this peristome inner rim.Chair legs 2 is taken turns the inboard of using rubber 5 by this, and the side of chair legs 2 clamps with rubber 5 by wheel, and Slipcover of chair leg 1 is contained on the Foot of chair 2.

In the inside bottom surface of this cladding parts 3, the sheet buffer unit 6 that is made of the sponge elastomeric material preferably is set (with reference to Fig. 9～Figure 11).By buffer unit 6 is set, because the end face of chair legs 2 directly contacts with buffer unit 6, so, can relax the impact that chair legs 2 when placing floor 7 (with reference to Fig. 9) to go up gives floor 7 to the chair of adorning Slipcover of chair leg 1.

When buffer unit 6 is set, adhesive (not shown) is set on buffer unit 6, preferably this adhesive can bonding chair legs end.In this case, buffer unit 6 is taken out in cladding parts 3, with adhesive buffer unit 6 is clung, the position of buffer unit 6 is not offset, can adorn cladding parts 3 in the chair legs end of this state in the end of chair.

In addition, can impose the design of all patterns, shown in legend, also petal-shaped margination part 8 can be set in the neighboring of the opening portion of cladding parts 3 to cladding parts 3.At this moment, can enlarge opening portion because grip margination part 8, so Slipcover of chair leg 1 can easily be put into chair legs 2.In addition, design is also very attractive in appearance.

Also have, the shape of clad material 3 is not particularly limited, for example both can be the almost plane square shape, or also can adopt circle to wait other shapes.

Fig. 6 is the state diagram that solid lubrication parts 4 shown in Figure 4 are removed suture 11.Fig. 7 is the A-A cutaway view of solid lubrication parts 4 shown in Figure 6, and Fig. 8 analyses and observe view for the B-B of solid lubrication parts 4 shown in Figure 6.

Solid lubrication parts 4 are the plate-shaped member that directly contacts floor 7, are the parts that chair can move freely on floor 7.The material of these solid lubrication parts 4, so long as coefficient of friction is little and have certain intensity to get final product, and be not particularly limited, can be hard material (non-pliability), perhaps also can be soft material (pliability), for example, can adopt polyethylene, polypropylene etc., wherein, it is only using polyethylene.

Because polyethylene has suitable hardness, coefficient of friction is little, can slide smoothly on floor 7, even and chair is slided, can not damage floor 7 yet, but damage solid lubrication parts 4, so can not damage floor 7 mistakenly.

In addition, in solid lubrication parts 4, as shown in Figures 3 and 4, what be formed with a plurality of plug wire holes 9 that can sew up cladding parts 3 and make the adjacent plug wire hole 9 lateral surface setting at this solid lubrication member 4 connected to one another receives duct 10.

In the 3rd embodiment, as taking out line termination portion 120 basic stitching action in addition, identical with first embodiment, second embodiment, the stitching action shown in Figure 14 a is carried out.

Figure 17 is the stereogram of Slipcover of chair leg the 4th embodiment of the present invention.Figure 18 is the side view of the Slipcover of chair leg shown in Figure 17.Figure 19 is the side view of the Slipcover of chair leg device shown in Figure 17 on chair legs the time.

Slipcover of chair leg 31 among the 4th embodiment is made up of the pedestal part 33 of direct contact floor 32 and the cladding parts 35 that is woven into rounded cylindrical, this cladding parts 35 be arranged on this pedestal part 33 above, mouth 34 is inserted and opening as chair legs in top.

Below, elaborate with regard to these inscapes.

Pedestal part 33 is born the load of chair 36 (with reference to Figure 23), and floor is passed in this load.Pedestal part is made of the little tabular solid lubrication parts of coefficient of friction.The material of lubricating component is so long as coefficient of friction is little and have certain intensity to get final product, and is not particularly limited, and can be hard material (non-pliability), perhaps also can be soft material (pliability), for example, can adopt polyethylene, polypropylene etc., wherein, it is only using polyethylene.

Because polyethylene has suitable hardness, coefficient of friction is little, can slide smoothly on floor 32, even and chair is slided, can not damage floor 32 yet, but damage pedestal part 33, so can not damage floor 32 mistakenly.

Shown in Figure 20 to 22, preferably pedestal part 33 form a plurality of plug wire holes 37 that can sew up with cladding parts 35 be arranged on that pedestal part 33 outsides are connected adjacent plug wire hole 37 receive duct 38.

Plug wire hole 37 is set to a plurality of, but there is no particular limitation its quantity and position.In illustrated example, plug wire hole 37 is along the mutual equally spaced configuration of the periphery of pedestal part 33.The stitching of pedestal part 33 and cladding parts 35 except the hand seam, can also be carried out machinery with sewing machine and make.

The duct 38 of receiving is the parts that are used to take in the suture 39 that adjacent plug wire hole 37 is coupled together that are configured in pedestal part 33 outsides.As long as the degree of depth of duct 38 received is to take in suture 39, be not particularly limited.Such formation even pedestal part 33 contacts with floor 32, owing to suture 39 does not directly contact with floor 32, thereby can prevent to be wiped when suture 39 from contacting with floor 32 disconnected.

In addition, pedestal part 33 plane visuals in the diagram are rounded, also can adopt other shapes such as square.In addition, from the aspects such as easiness of the easiness made, intensity, use, the plane visual shape of preferred pedestal part and the plane visual of cladding parts 35 are shaped as identical shaped.

Cladding parts 35 is used for coating the side face of chair legs 310 ends.Cladding parts 35 is made of the quality with retractility.The retractility quality is meant through circular knitting machine, for example the quality that knits out of socks circular knitting machine.In the present invention, this circular knit is made of the rubber braiding.In general, the weaving method that constitutes circular knit has all kinds such as flat sennit, and the retractility that the rubber braiding of being adopted among the present invention is compared on transverse direction with other braiding is far better, has significant laterally elastic force.Constituting not special qualification of kind of the line of this rubber braiding, for example also can be to be made of 100% bombax cotton.If but can, the preferred use has the fiber of good retractility, as contains the formation of elastomers such as polyurethane fibre.Elastomer is the fiber that demonstrates the above expansion and contraction of 500% (6 times) under the situation of polyurethane fibre.If the containing ratio of such a elastomer in the braiding quality reaches 20%, the retractility of so above-mentioned rubber braiding quality can be outstanding.

The one or both ends of this cladding parts 35 are the tubular (illustrated example among Figure 21,22 is a both ends open) of opening.The cladding parts 35 of rubber braiding, its braiding quality all have a very big retractility in that vertical and horizontal are two-way, and great retractility is particularly arranged in the horizontal.Thus, can be to be close to state device in chair legs end from the thin chair legs end of bore to the various bores of the thick chair legs end of bore.No matter the chair legs end is columns such as cylindrical, cube cylindricality, or different shape such as spherical, and cladding parts can both positively be close on whole basically side face of those chair legs ends.Particularly when the end of chair legs when being spherical, for cladding parts 35, flexible requirement on the direction of footpath and axial each position have nothing in common with each other, the part requires retractility remarkable, and by resembling the circular knit quality that constitutes by the rubber braiding of the present invention, can positively satisfy this requirement, can positively reach at each position and be close to.

Cladding parts 35 is under the situation of shape of the no end of both ends opening, openend periphery radius vector direction inside bend on one side can be formed inside blade of a sword shape portion 311 (with reference to Figure 21,22), and this blade of a sword shape portion 311 is sutured in pedestal part 33.

Cladding parts 35 is under the open-ended situation that end shape arranged, and its bottom can be sutured in pedestal part 33.

Buffer unit 313 preferably is set on pedestal part 33.By buffer unit 313 is set, because the front end face and the buffer unit 313 of chair legs 310 join, the impact of 310 pairs of floor 32 of chair legs in the time of can relaxing chair and be placed on the floor 32.

For instance, buffer unit 313 can the cloth material covers sponge, cotton and constitutes.Buffer unit 313 can be installed on the pedestal part 33 by the whole bag of tricks, for example can install by the mode of sewing up.

Because cladding parts 35 can fully coat the chair legs end of different shape, size, and can positively be close to the whole peripheral surface basically of this end, therefore even when on floor 32, pulling chair 36 it being slided, can not make cladding parts 35 produce dislocation with respect to the chair legs end yet, and, can prevent slip (the two-way slip of chair legs axial length direction and footpath direction) with respect to the cladding parts 35 of chair legs end.In addition, (promptly mill volume: cladding parts 35 Off ライス Knitting body) is that the axial length direction also has very big retractility at longitudinal direction, therefore can positively coat the chair legs end of all lengths by woven the circle that is woven into that constitutes by rubber.

Next, describe with reference to the using method of accompanying drawing at Slipcover of chair leg.Constituting pedestal part (33) with the solid lubrication parts here, is that example describes.

At first, launch the peristome of cladding parts, insert the first end of chair legs 310 from this peristome.Shown in Figure 21,22, the front end face of chair legs 310 and buffer unit 313 are joined, Slipcover of chair leg 31 is loaded on the end of chair legs 310.Next, on floor 32, place chair 36, pedestal part 33 and floor 32 are joined.

When mobile chair 36, by drawing or pushchair 36,, thereby chair 36 just can be slided at an easy rate because pedestal part 33 slides on floor 32 swimmingly along floor 32.At this moment, because the whole peripheral surface basically of the end of chair legs 310 all is close to by cladding parts 35 with fitting together perfectly, therefore at the suturing part of pedestal part 33 with cladding parts 35, on full week, apply the impartial power that is close to usually, can on the suture 39 that connects them, not apply compulsory power, so played the effect that prevents suture 39 deteriorations.In addition, because chair legs 310 ends whole peripheral surface are basically all keeping being close to state with cladding parts 35 with fitting together perfectly, make chair legs 310 ends on pedestal part 33, can not misplace, can prevent that the buffer unit 313 on the pedestal part 33 from producing deterioration owing to friction waits.

Also have, in the present invention, not necessarily leave no choice but on pedestal part 33, be provided with the plug wire hole 37 and the duct 38 of receiving.When these devices are not set, for example, can be pedestal part 33 and cladding parts 35 is fixing with adhesive.Under the situation that plug wire hole 37 only is set, suture 39 can be passed plug wire hole 37 and cladding parts 35 and stitching pedestal part 33 and cladding parts 35.

According to Slipcover of chair leg of the present invention, because suture clamps cladding parts from two sides, so this clamping position that forms on suture becomes the line termination portion of taking out of suture self.In this case, even suture is just in case rupture, sutural extraction will be taken out line termination portion at this and will be blocked, and the influence of sutures breaks can not propagated by taking out line termination portion.

According to Slipcover of chair leg of the present invention, can prevent sutural extraction more reliably.

According to Slipcover of chair leg of the present invention, the seam caudal knot portion that suture forms becomes the line termination portion of taking out of suture itself.In this case, even suture is just in case rupture, sutural extraction will be taken out line termination portion at this and be blocked, and the influence of sutures breaks can not propagated by taking out line termination portion.

According to Slipcover of chair leg of the present invention, in cladding parts, take out buffer unit, with adhesive buffer unit is installed in the chair legs end, the buffer unit position is not departed from, can chair legs end in this state be installed by cladding parts, can correctly be fixed on the chair legs end to buffer unit.

According to Slipcover of chair leg of the present invention,, chair is slided swimmingly on floor because the pedestal part that is made of the solid lubrication parts is set.In addition, because the whole peripheral surface basically of the end of chair legs is close to by cladding parts with fitting together perfectly, therefore at the suturing part of pedestal part and cladding parts, on full week, apply the impartial power that is close to usually, can on the suture that connects them, not apply compulsory power, so played the effect that prevents the suture deterioration.In addition and since the chair legs end basically whole peripheral surface all keeping being close to state with cladding parts with fitting together perfectly, make the chair legs end on pedestal part, can not misplace, can prevent the buffer unit on the pedestal part because friction grade produces deterioration.

According to Slipcover of chair leg of the present invention, on described pedestal part, a plurality of plug wire holes that formation can be sewed up with described cladding parts, because suture passes part or all and cladding parts of this plug wire hole and pedestal part and cladding parts is stitched together, and makes pedestal part positively install by the effect of line.

According to Slipcover of chair leg of the present invention, on described pedestal part, form the duct of receiving that connects adjacent plug wire hole in the outside of this pedestal part, because the suture that will connect adjacent plug wire hole (37) is configured in part outside the pedestal part and is accommodated in aforesaid receiving in the duct, can prevent the sutural deterioration that produces owing to the friction with floor.
