Description

[0026] Hereafter, the invention will be further described by means of a drawing. The drawing shows in:

[0027] FIG. 1 a side view of the device according to the invention,

[0028] FIG. 2 a sectional view of the device according to the invention,

[0029] FIG. 3 a perspective explosion view of the device according to the invention,

[0030] FIG. 4 an explosion view from the side of the device according to the invention,

[0031] FIG. 5 a sectional explosion view of the device according to the invention, and

[0032] FIG. 6 a perspective view of the device according to the invention, a tire and a pump.

[0033] The same and similar parts and features have been denoted by the same reference numerals in the figures. However, for ease of understanding the figures, not all parts that are required for a practical embodiment have been shown in the figures.

[0034] FIG. 1 shows a side view of the device 1 according to the invention. The device 1 comprises a body 2 with a connector 3 for a hose of a pump (not shown in this figure). The hose may be clampingly fitted as such or a hose clamp may be applied. An elastic band 4 is coupled to the body 2. A first end 5 of the band 4 is coupled to a first side 6 of the body 2 whereas the band 4 is coupled to the body 2 at a remote position 7 to an opposite side 8 of the body 2. Hence, the elastic band 4 forms a loop.

[0035] Coupling of the band 4 to the body 2 is easily obtained by means of notches 9, for example at the body 2, for mutual cooperation with openings 10, for example in the elastic band 4. As shown also in FIG. 1 and FIG. 2, the band 4 may comprise a notch 19 for positioning behind a shoulder 20 of a coupling member at the body 2.

[0036] FIG. 2 shows a sectional view of the device shown in FIG. 1. The parts as referred to in the description of FIG. 1 can be easily recognized. In addition, FIG. 2 shows the fluid flow path 11 (indicated by a dashed line) gas will flow when operating the pump referred to above for inflating a tire (not shown). The flow path extends from the connector 3 to an opening 13 in the body 2 for receiving a valve of a tire.

[0037] The band 4 comprises a plurality of openings 10 so as to be able to increase or decrease the length of the loop.

[0038] FIG. 2 shows an insertable piece 12 in the body 2. This insertable (and removable) piece 12 comprises a pump nipple 12 for receiving a valve (not shown) of the tire to be inflated. The tire's valve is to be received in the recess 13 through access opening 14, as shown in FIG. 5. Since the inside wall 15 (also as shown in FIG. 5) of pump nipple 12 is tapering towards the inside, the depth to which the valve is inserted depends on the diameter of said valve and said inside wall 15. Valves of many different sizes can be used with the present pump nipple 12 due to the tapering wall 15.

[0039] In FIG. 3 an explosion view of the device 1 has been shown. The body 2 and the insertable pump nipple piece 12 as well as the elastic band 15 are clearly distinguishable in this drawing.

[0040] FIG. 4 and FIG. 5 show an explosion view of FIG. 1 and FIG. 2, respectively.

[0041] Finally, FIG. 6 shows a perspective view of the device 1 in operation. A valve of a bicycle tire 16 is inserted in the recess 13 of the pump nipple 12. A hose 17 of a pump (not shown) is connected to the connector 3 of the device 1, such that when operating the pump air will be moved through the fluid flow path 11, inflating the tire 16. The elastic band 4 is guided over the tire 16 and rim 18 and is coupled to the device 1.

[0042] The invention is not limited to the embodiments as mentioned above and as shown in the drawings. The invention is limited by the claims only.

[0043] The invention also relates to all combinations of features described here independently of each other.
