Abstract

(57) [Summary] [Purpose] It is possible to hang it on the wall of a warehouse, etc., and to organize it during storage and improve its appearance. [Structure] The handle stay side flange (3) and the cylinder side flange (5) can oppose each other, and are gripped by the dragonfly (6) at the end of the hose when they are facing each other. As a result, the cylinder (4) is securely locked to the handle stay (2), and the air pump can be suspended on the wall.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air pump for injecting air into a bicycle tire or the like.

[0002]

[Prior art]

 Generally, the air pump is stored with the dragonfly 6 locked to the spring 15 when not in use, as shown in FIG.

[0003]

[Problems to be solved by the device]

 However, in the conventional air pump, the dragonfly 6 is generally held upright against the wall of the warehouse while the dragonfly 6 is locked by the spring 15. It was impossible because the cylinder 4 was lowered due to its own weight, and the storage was poorly organized, and the appearance was spoiled.

In view of the above points, the present invention provides an air pump that can be hung on the wall of a warehouse, etc., and has an object to improve the arrangement and aesthetics during storage.

[0005]

[Means for Solving the Problems]

 In order to solve such a problem, the air pump according to the present invention is provided with a handle stay side flange and a cylinder side flange which can be opposed to each other, and each flange is gripped by the dragonfly at the end of the hose in the opposed state. Is characterized by.

[0006]

[Operation and effect of the device]

 When the air pump according to the present invention is not used, the handle stay side flange and the cylinder side flange are held by the dragonfly at the tip of the hose with the flange facing each other. Therefore, when this air pump is hung on the wall of a warehouse, the cylinder can be securely locked to the handle stay, and the cylinder can be prevented from dropping due to its own weight. Therefore, it is possible to organize the storage and improve the appearance.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

Most of the air pump according to this embodiment is made of synthetic resin, and a handle stay 2 having a handle 1 at the upper end is provided with a flange (handle stay side flange as shown in FIG. 3 at the lower end. ) 3 is formed. Further, a flange (cylinder side flange) 5 as shown in FIG. 3 is also formed on the upper end of the cylinder 4.

The handle stay side flange 3 and the cylinder side flange 5 are illustrated when the air pump is not used, that is, when the piston rod 2 b connected to the handle stay 2 is accommodated in the cylinder 4. As shown in 2, they face each other with almost no gap. In this facing state, the handle stay side flange 3 has the first base member 6a (see FIGS. 2 and 4) of the recess 6 and the cylinder side flange 5 has the second base member 6b (see FIGS. 2 and 4). 2) is locked by the elastic biasing force of the spring member 6c (see FIG. 2) of the dragonfly 6, and the handle stay side flange 3 and the cylinder side flange 5 are sandwiched by the dragonfly 6, as shown in FIG. It is configured .

As shown in FIG. 3, the lower end surface of the handle stay 2 and the upper end surface of the cylinder 4 are provided with a pair of convex portions 7 and concave portions which are matingly connected to each other when the flanges 3 and 5 are opposed to each other. 8 are formed, and one pair or plural pairs (two pairs in FIG. 3) of the pair of protrusions 7 and recesses 8 are formed. Since the handle stay 2 is rotatable with respect to the cylinder 4, the pair of protrusions 7 and recesses 8 perform a positioning action when the flanges 3 and 5 are opposed to each other.

Further, as shown in FIG. 1, a horizontal through hole 10 for passing the hook 9 when the air pump is hung on the wall is formed in the center of the handle 1. In the figure, the other reference numeral 11 represents a hose and 12 represents a floor.

As described above, in the air pump according to this embodiment, when not in use, the handle stay side flange 3 and the cylinder side flange 5 are held by the dragonfly 6 in a state of facing each other, and the through hole is formed. It is hung on the wall of the warehouse through the hook 9 at 10. Therefore, the cylinder 4 can be securely locked to the handle stay 2, and the cylinder 4 can be prevented from being lowered due to its own weight, so that the storage can be organized and the appearance can be improved.

It should be noted that instead of the handle stay side flange 3 and the cylinder side flange 5, the handle stay 2 is configured in the same manner as in the above embodiment by forming locking recesses into which the hoses 11 can be fitted. Alternatively, the cylinder 4 may be securely locked.
