Description

DETAILED DESCRIPTION OF THE INVENTION [First technical field] This invention relates to a mounting structure for a valve cap of an automobile wheel cover.

[Prior art]

As a conventional valve structure of this type, there is one shown in FIG. 7 and subsequent figures, for example. That is, conventionally, the wheel cover body 1 that is attached to the surface side of the rim is decorated with decorative properties, and the cover interior is provided with ventilation to prevent heating and corrosion of the wheel rim 19. In order to prevent this, a large number of air vent holes 1a are formed at intervals in the circumferential direction as shown in the example, which are approximately rectangular in shape and have sloped portions on the inside. Among the 13 groups of air vent holes, In order to inject pressurized air into the tire through a tube 20 installed at one end of the inner rim 19, a part of the inner rim 19 is used for fitting an air injection nozzle 21 into this tube 20 from the outside. Since the somewhat large openings 2X, which serve as nozzle insertion operation openings, were provided in a mixed manner, there were the following drawbacks.

(11) Since the opening 2X is somewhat large, the missing mass becomes large, and the center of gravity of the wheel cover main body 1 is slightly higher than the axis.As a result, the cover main body 1 There was rattling, and an air vortex was generated at the position of the opening 2X, which caused wind noise.

(2) Somewhat large openings 2X are mixed in the part where the above-mentioned ventilation holes 1a are arranged at intervals, so
The appearance of the wheel cover body 1 was significantly impaired.

[Summary of Katsumei]

In this application, a cap that closes this opening is attached to the periphery of an opening installed in a part of the ventilation hole group of the wheel cover main body, and a cap that closes this opening forms the main part, and an opening is provided on the back side of the cap. For the above-mentioned installation on the peripheral side of the cap, a locking part that can be secured is provided at the main part, and an operation opening in the same shape as the other ventilation holes is opened in the center of the cap so that it can be attached and removed freely. This structure eliminates the above-mentioned drawbacks, and will be explained in detail below using examples.

[Arashi and Nobu's examples]

FIG. 1 to FIG. 4 show an embodiment for this @. The wheel cover main body 1 in this embodiment is constructed as follows. That is, on the surface near the outer periphery of the cover main body 1, a large number of ventilation holes 1a having substantially the same shape as the conventional one are formed at intervals in the opening direction. A somewhat large, approximately rectangular opening 2, which serves as a nozzle insertion operation opening when injecting air into the tire through a tube 20 installed at one end of the rim 19, is intermixed through the rim 19. On the inner side of the four sides of the opening 2 except for the outer periphery side, a slightly wider periphery 2a is formed one step lower, which will serve as a receiving surface when a camp 3 to be described later is attached to the opening 2 in the same plane. ing. A small rectangular locking hole 4 is provided at the left and right positions on one side of the peripheral edge 2a near the axis. In addition, in order to form an engagement air zone E having a partially open rectangular shape on the peripheral edge 2a between the locking holes 4, one side thereof is held in an L-shape in a plan view to hold the support column 5. A piece 6 is formed to protrude from the peripheral edge 2a toward the opening 2. On the other hand, a receiver having an inverted shape when viewed from the front is formed such that the piece 7 is similarly located on the opening 2 side. Next, cutout portions 8 having a slight width are provided at midway positions on the left and right sides of the peripheral edge 2a. Furthermore, the opening 2 near the outer periphery of the cover main body 1
On the other side, a fitting airspace zone F is formed at an intermediate position, and a slightly wide band-like position is formed on the left and right sides as follows. That is, as clearly shown in FIG. 4, this cap 3 has the above-mentioned air vent hole in the lower middle band of the lid body 10 which can be fitted in the peripheral edge 2a of the opening 2 in a flush manner. An operation port 3a having substantially the same shape as 1a is formed. Projecting pieces 11 that can be inserted into the locking holes 4 on the opening 2 side are provided on the upper half of the back side of the cap 3 on the left and right sides of the uppermost position. The surface between the projecting pieces 11 fits into the engagement air zone E on the opening 2 side, and the receiver next to it can be placed on the plane of the piece 7, and when viewed from the front, A plate-shaped locking piece 12 is protruded from the upper side in a substantially horizontal plane so as to form an inverted letter shape, and a connecting piece 13 is formed in a vertically descending shape on a part of the front end side of this locking piece 12. There is. A downward claw 15 is provided at the tip of the locking piece 12 on the side where the connecting piece 13 is not formed, which can be engaged with the holding piece 6 adjacent to the engagement air zone E described above. Further, a slope-shaped pressing piece 14 is integrally attached to the lower end of the connecting piece 13 and is slightly higher on the front end side. A downward claw 16 is provided on the front edge of the pressing piece 14.

In addition, at the center of the back surface of the lower end side of the lid body 10, which is located directly below the operation port 3a, there is a lock that can be inserted into the fitting air area F on the opening 2 side and engaged and fixed to the back surface of the main body 1 at this position. Claw piece 18
is provided in a downwardly protruding manner, and the overall structure is such that the cap is attached to the pulp part of the wheel cover.

Since the present embodiment is constructed as described above, when attaching the cap 3 to the opening 2 of the wheel cover main body 1, as shown in FIG. After inserting the piece 18 into the fitting space vIF formed between the displacement regulating pieces 9 of the opening 2, this locking claw piece 18
When the upper side of the lid 10 is brought close to the peripheral edge 2a of the opening 2 using the fulcrum as a fulcrum, the locking piece 12 protruding from the upper part of the back surface of the lid 10 engages the engagement air zone E of the opening 2. Insert into the inside,
At the same time, the top surface of the connecting piece 13 contacts the upper surface of the piece 7 of the partition receiver. At the time of this contact, the claw 1 of the locking piece 12
5 is locked to the holding piece 6 adjacent to the airspace belt.
This cap 3 can be smoothly and reliably attached to the position of the opening 2. Note that when the cap 3 is attached as described above, the protrusion 11 and the small protrusion 17 of the cap 3 fit into the locking hole 4 of the peripheral edge 2a of the opening 2.
Since the cap 3 is inserted into the notch 8, the cap 3 is guided and positioned when the cap 3 is inserted, and therefore the cap 3 can be attached even more easily. When the cap 3 is attached as described above, the lid body 10 is fitted into the peripheral edge 2a of the opening 2 flush with the same surface, so that it looks like the opening is not visible as shown in FIG. 2 disappears, and an operating port 3a having the same shape as the other 18 groups of air vent holes is located in this part, so that only the air vent hole 1a is provided on the surface near the outer periphery of the wheel cover main body 1. The same appearance can be obtained by arranging them in the circumferential direction.

When removing the cap 3 from the position of the opening 2, as shown in FIG. When the distal end is inserted and pushed upward with the distal end in contact with the claw 16 of the pressing piece 14 located at the upper inner side of the operation port 3a, the fifth
As shown in Figure +d), the claw 15 of the locking piece 12, which had been locked to the holding piece 6 on the opening 2 side, separates from the holding piece 6 due to the above-mentioned pushing up operation, so at this point The manner in which the cap 3 is attached to the opening 2 is released. Therefore, by pulling the upper end of the lid body 10 outward immediately after this, the cap 3 can be removed smoothly and easily.

The above-described removal of the cap 3 is not limited to the use of the jig P using a screwdriver or the like. For example, although not shown, the same removal can be easily and reliably performed using a fingertip or the like by performing the same operation as described above.

Note that the opening 2 from which the cap 3 has been removed is formed in almost the same position as the conventional opening, so insert the air injection nozzle from this position in the same manner as shown in FIG. Work air can be supplied to tires (not shown) through the tube 20.

In the above embodiment, the ventilation hole 1a is configured to have a substantially rectangular shape, but the present invention is not limited to the above shape, and may be, for example, circular or oval. Further, the above-mentioned ventilation holes are not necessarily arranged at regular intervals with a partial pitch, but may be configured such that a plurality of ventilation holes are combined to form one unit of ventilation holes, as shown in FIG. 6, for example.

[Effect of 1% water] As explained above, this tbq has the following effect:
To attach the cap that closes this opening, form the main parts such as a positional displacement regulating piece with a fitting air area band and a holding piece with an engaging air area band, and also attach the above-mentioned attachments on the periphery side of the opening to the back of the cap. In addition to providing a locking claw piece or a locking piece with a claw that can be engaged with the main part of the cap, the lid body of this cap has an operation opening of the same shape as the other ventilation holes. Since the cap is opened and attached in a detachable manner, the cap can be easily and securely attached to the opening, and once attached, the cap can be pressed from the outside via a pressing piece to release the locking piece. It will not come off unless the claws are released from the holding piece. In other words, when the cap is attached to the opening, the claw of the locking piece that is locked to the holding piece on the opening side faces downward, and after the cap is attached, it faces the outside of the wheel cover body. Therefore, when the cover main body is rotated, the centrifugal force can not only easily and reliably prevent the cap from coming off from the opening, but also further increase the ability to hold the cap in place by the centrifugal force. In addition, since a pressing piece is provided directly below the locking claw piece, the cap can be removed by pushing up on this pressing piece, so there is no need to damage the cap or the surface of the wheel cover body. Moreover, when the cap is attached to the opening position, the lid body is fitted flush with the circumferential surface of the opening, and only the ventilation holes are arranged in the circumferential direction in the cover body. Since the condition remains the same, the appearance of the wheel cover can be greatly improved.
