Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pillars catch that is pressed against a wall covering or the like to detect the position of a base material under the covering according to the degree of pin needle sticking. Is.

[Problems to be solved by conventional techniques and devices]

Conventionally, a pin needle for sticking to a wall surface tool is protrudingly provided at the tip of the handle and a push guide fitted to the pin needle is press-fitted into the handle, and the handle is gripped and held. When the push guide at the tip is pressed against the wall surface tool and press-fitted into the grip handle, the pin needle protrudes from the tip of the push guide and is inserted into the wall surface tool. There is a Pillars catch to detect.

This type of Pillars catch does not look dangerous because a dangerous pin needle is not fitted and protruded by the push guide, but just pressing the push guide causes the push guide to be pressed by the slight pushing force. Since the pin needle is pressed into and protrudes by that amount, and for example, the pin needle is stuck in the pressed hand, on the contrary, it is even more dangerous because it does not look dangerous.

Therefore, a cap that prevents the pin needle from protruding when not in use is required.

Conventionally, a separate cap having the same diameter as the push guide was simply used at the tip of the push guide.

However, in this case, the cap had to be removed one by one, so that there was a problem that the cap was lost, and finally it was troublesome to close the cap, and the cap was left in a dangerous state without the cap.

The present invention provides a Pillars catch that solves these drawbacks.

[Means for Solving the Problems]

 The detailed description will be made with reference to the accompanying drawings.

A pin needle 2 is provided so as to project from the tip of the handle body 1, a push guide 3 fitted on the pin needle 2 is press-fitted into the handle body 1, and the push guide 3 is pressed to press the handle body 1. In the pillars catch in which the pin needle 2 protrudes from the tip of the push guide 3 when it is press-fitted into the inside, the cap 5 having the open opening 4 at the tip is fitted on the tip of the handle body 1 to cover the cap 5. Push the push guide 3 out of the open opening 4,
A lock mechanism a for locking this state and a lock mechanism b for locking the state in which the push guide 3 is slid into the cap 5 by sliding the cap 5 are provided on the tip end portion of the handle body 1 and the inner peripheral portion of the cap 5. The present invention relates to a pillars catch, which is characterized in that

[Action]

A state in which the push guide 3 fitted with the pin needle 2 is projected from the open opening portion 4 of the cap 5 (for example, FIGS. 1 and 2).
The state shown in the figure) is locked by the lock mechanism a and the tip of the protruding push guide 3 is pressed against a surface tool such as a wall to use the product.

When the product is not used, the lock mechanism a is released, and the state in which the cap 5 is slid forward to immerse the push guide 3 in the cap 5 (for example, the state shown by an imaginary line in FIG. 3) is the lock mechanism b. To lock.

In this state, since the push guide 3 is immersed in the cap 5, even if the tip of this product is accidentally pressed against, for example, the palm, this pressing force is applied to the locked tip of the cap 5 and It is not given, and the pin needle 2 does not stick into the palm, for example.

〔Example〕

Referring to the attached drawings, a lock mechanism a for locking the push guide 3 from the open opening 4 of the cap 5 for locking the use state and a lock mechanism for retracting the push guide 3 in the cap 5 for locking the unused state Mechanism b
Will be described in detail.

An L-shaped guide groove 6 as shown in FIG. 4 is formed on the surface of the grip handle 1 at which the cap 5 is fitted, and overcoming projections 7a and 7b are formed at both ends of the L-shaped guide groove 6. On the other hand, on the inner peripheral surface of the attachment ring 5 ″ of the cap 5 provided with the attachment ring 5 ″ at the base end of the tubular body 5 ′, the protrusion 8 that fits into the L-shaped guide groove 6 is provided.

A lock mechanism that locks by sliding the cap 5 along the L-shaped guide groove 6 and the projection 8 on the inner peripheral surface of the attachment ring 5 ″ of the cap 5 gets over the protruding ridges 7a, 7b of the L-shaped guide groove 6. The case where a and b are adopted is illustrated.

That is, FIG. 3 shows a state in which the push guide 3 is projected from the open opening 4 of the cap 5 and the use state is locked. From this state, the cap 5 is pushed forward and the mounting ring 5 ″ of the cap 5 is pushed. This lock state is released when you get over the projection 8 on the peripheral surface and get over the projection 7a,
The cap 5 can smoothly slide forward.

The cap 5 moves forward along the L-shaped guide groove 6, and the projection 8 on the inner peripheral surface of the mounting ring 5 ″ of the cap 5 is exactly the mounting ring 5 ″ provided at the tip of the grip handle 1 to prevent slippage. Slide the push guide 3 into the cap 5 by sliding it to the corner 6'of the L-shaped guide groove 6 that hits, and rotate the cap 5 along the L-shaped guide groove 6 to make the protrusion 8 L-shaped. When the push guide 3 is pushed over the ridge 7b at the end of the guide groove 6, the push guide 3 is locked in the unused state where the push guide 3 is retracted into the cap 5.

In order to return to the use state shown in FIG. 3, the reverse operation may be performed.

Therefore, as shown in FIG. 2, the operation is "OPEN", the unused state is "LOCK", and the operation indicated by the arrow on the cap 5 is appropriately performed.

The drawing shows a case where two L-shaped guide grooves 6 and two protrusions 8 are formed at symmetrical positions.

Further, in the figure, reference numeral 10 is a pin needle stopper, 11 is an inner chamber for accommodating a spare pin needle and the like, 12 is a pin needle guide, and 13 is a spring.

[Effect of device]

Since the present invention is configured as described above, the cap is neither removed nor lost as compared with a conventional separate cap.

In addition, it is possible to lock the usage state with the push guide protruding from the opening opening of the cap and the unused state with the push guide immersed in the cap, so it can be safely left and used. The cap is a pillars catch that is extremely practical and does not cause any inconvenience in use.
