Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an armrest for a stroller on which an infant is carried. This relates to the armrest rod of a stroller made up of the following structures.

[Prior art and its problems]

2. Description of the Related Art So-called baby strollers for carrying and carrying infants are known to have various structures.

These are widely known as those with a so-called reclining mechanism that allows the relationship between the seat part on which the infant is placed and the backrest part to be freely changed from a seated state to a lying state. It is being

In addition, a U-shaped guard is removably attached to the end of the armrest provided on both sides of the seat so that it can be inserted into the fitting hole. It is also already known that a stroller is configured to prevent an infant seated in a stroller from falling off the tip of the seat floor.

However, in the case of the above-mentioned known structure, when the use of the guard is not required, the fitting hole drilled at the tip of the guard is exposed as it is, which not only looks unsightly but also interferes with the seat floor. It has been pointed out that unexpected trouble may occur if a seated infant inserts his or her fingertip into this fitting hole.

In order to address these problems, the applicant of the present application proposed a device in which the above-mentioned fitting hole can be covered with a removable cover plate when the guard is not in use as Utility Application No. 125713/1983. I suggested it, but
In the case of this invention, since the cover plate that closed the fitting hole was simply fitted, there was a possibility that the cover plate might come off while a child was playing with it, and it could not be said to be perfect.

[Purpose of invention]

In view of the above-mentioned circumstances, the present invention attempts to address these shortcomings, and includes a lid plate that closes the fitting hole drilled at the tip of the armrest, which is firmly attached to the armrest, and which prevents the instrument from being mounted. It is configured so that it cannot be removed unless it is used, and the cover plate attached to the armrest can form a part of the armrest, creating a beautiful structure that looks identical in appearance. The aim is to provide armrests for baby strollers.

Another object of the present invention is to provide an armrest for a stroller whose cover plate can be instantly removed using a simple tool such as a coin or a screwdriver.

[Key points of the idea]

The present invention provides an armrest in which a guard fitting hole is drilled in the end end of the armrest, and a cover plate is attached and detached so as to be flush with the end when fitted into the fitting hole. The cover plate is configured to be able to engage with the back surface of the end portion of the armrest by means of locking protrusions protruding inward at both upper and lower ends, and the locking protrusions engage The key point of the invention is that an operating hole is formed on the lower surface of the matching armrest for releasing the aforementioned locking protrusion.

〔Example〕

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

It should be noted that, although the embodiments show examples of structures most suitable for implementing the present invention, the present invention is not limited to this structure.

Reference numeral 1 denotes a front leg brace, and numeral 2 denotes a rear leg brace. These two leg braces 1 and 2 are pivotally connected to the tip of the armrest 3 at the upper end via a pivot, and the two leg braces can be opened and closed by opening and closing operations. The interval between 1 and 2 is such that it can be opened and closed in a lateral 8-shape.

4 is a handrail formed in a U-shape from the front;
Its base end is pivotally attached to the longitudinally intermediate portion of the rear leg brace 2 via the folding operation bracket 5, and the rear end of the armrest brace 3 is pivotally attached to a portion slightly above the base end. are doing.

The above-mentioned folding operation bracket 5 has a substantially L-shaped side surface, and has a lower end mounted parallel to the rear leg bar 2 and pivotally attached to the rear leg bar 2. The lower end of the pusher 4 is pivoted, and the distal end portion thereof is brought into contact with the back surface of the rear leg lever 2 (the upper surface of the shaft along the length direction) while being parallel to the rear surface.

6 is a planar U-shaped guard attached to the tips of the two opposing armrests 3, 3, and is made of foamed urethane resin or other material with appropriate elasticity. At the same time, there are fitting pipes 61, 61 which serve as core materials inside.
It is made to protrude by a small length.

Reference numeral 62 denotes a locking protrusion that is attached so as to be freely retractable near the tip of the pipe 61 for fitting, and a spring 63 provided inside the pipe 61.
It is constantly urged to protrude outward by the repulsive force of.

Note that the fitting pipe 61 can be configured to be attached only to both ends of the guard 6, but in order to have the function as a reinforcing core that increases the strength of the guard 6, the planar shape of the guard 6 is It is desirable to use a pipe formed in the same shape as that of the guard so that it can be buried or installed inside the guard over its entire length.

Reference numeral 31 denotes a fitting hole formed at the tip end of the armrest 3 in order to fit fitting pipes 61, 61 projecting from both ends of the guard 6; A receiver 7 is attached for inserting and supporting a fitted pipe 61.

In addition, a fitting hole 71 having a size in which the fitting pipe 61 can be fitted is bored in the receiving tool 7 in the horizontal direction, and a part of this fitting hole 71 has a fitting hole 71 in which the fitting pipe 61 can be fitted. A locking hole 72 is bored into which a locking protrusion 62 protruding from the hole 72 is fitted and locked.

73 is a locking protrusion 62 fitted into the locking hole 72
When the release operation plate 73 is lifted, an operation protrusion 74 formed upward in the center of the locking hole 72 projects from the lower surface of the locking hole 72, thereby locking the locking hole 72. The projection 62 is pushed out from the locking hole 72 to release the engagement.

Reference numeral 8 denotes a cover plate for closing the fitting hole 31 formed at the end end portion of the armrest 3, which closes the fitting hole 31 which is exposed when the guard 6 is removed.

This cover plate 8 has locking claws 81, 82 protruding inward from both upper and lower ends of the peripheral edge, and by locking the locking claws 81, 82 to the back side of the wall surface of the armrest 3. Thus, the closed state by the cover plate is firmly maintained, and the cover plate 8 is prevented from being unduly separated from the armrest 3.

The locking pawl 82 protruding from the lower side of the periphery of the cover plate 8 is formed in the shape of an elastic arrowhead, and the locking pawl 82 is formed in the shape of an elastic arrowhead, and the locking pawl 82 is formed in the shape of an elastic arrowhead, and the locking pawl 82 is formed in the shape of an elastic arrow. A push-up tool 9 such as a coin inserted through the bottom portion 32 pushes up this arrow-shaped locking claw 82, thereby releasing the engagement with the armrest 3.

The cover plate 8 is formed to be flush with the surface of the end end portion of the armrest 3 when it is fitted into the fitting hole 31 formed at the end end end end portion.

[Operation of the invention] When using a guard In this case, a fitting hole 31 that is exposed at the tip of the armrest 3 by removing the cover plate 8 is provided with a fitting hole that protrudes from both ends of the guard 6. When the pipe 61 is fitted, it is immediately inserted into the fitting hole 71 of the receiver 7 attached to the back side of the armrest 3.

The locking protrusion 62 formed on the pipe 61 fitted into the fitting hole is initially pushed up by the wall surface of the fitting hole 71 when inserted into the fitting hole 71 of the receiver 7 and sinks into the pipe. However, as the pipe 61 advances, when it reaches the drilling position of the locking hole 72, it immediately protrudes and engages the two, whereby the guard 6 is prevented from protruding. It is now firmly held by the armrest 3.

If you want to remove the guard 6 fixed to the tip of the armrest 3 by the operation described in ``When removing the guard,''
Receiver 7 attached to the inside tip of armrest 3
The opening operation plate 73 is pushed upward from its lower surface.

When the opening operation plate 73 is pushed up, the operation protrusion 74 formed on the opening operation plate enters into the inside of the locking hole 72 formed in the receiver 7 from the back side, and as a result, it is fitted into the locking hole 72. The engaged locking projections 62 are pushed up against the force of the spring 63, and the engagement between the fitting pipe 61 and the receiver 7 is released.

The pipe 61 whose engagement between the locking protrusion 62 and the locking hole 72 has been released can be easily removed by pulling it out in the opposite direction to the insertion direction.

When installing a cover plate After removing the guard 6, a fitting hole 31 is exposed at the tip end of the armrest 3, so fit the cover plate 8 into this fitting hole 31, and then attach the cover plate 8. As a result, the entire surface of the gable surface can be closed.

When inserting the cover plate 8, first, a locking claw 81 formed protruding from the upper end of the periphery of the cover plate 8 is inserted into the insertion hole to lock the upper surface of the cover plate 8.

Next, the other locking claw 82 formed protruding from the lower end of the periphery is pushed in, and the entire surface of the cover plate 8 is fitted into the insertion hole.

Since the above-mentioned locking claws 81 and 82 are locked to the back side of the armrest 3, the cover plate 8 fitted into the insertion hole 31 is strong and has no risk of detaching from the armrest 3. This will ensure proper retention.

When removing the cover plate In this case, use a thin metal plate like a coin or a push-up tool 9 like a thin screwdriver to remove the space exposed between the back side of the armrest 3 and the receiver 7. Insert into the bottom part 32. (See FIG. 4) The push-up tool 9 pushes up the locking claw 82 formed at the lower end of the cover plate 8 from below.

As the locking claw 82 is forcibly pushed up by the push-up tool 9, the engagement with the back side of the armrest 3 is released. The locking force is no longer guaranteed and it immediately pops out to the front side of the armrest 3 and is removed.

[Effect of idea]

Since the present invention is configured as described above, the guard 6
The insertion hole 31 drilled in the tip (end portion) of the armrest 3 can be closed by the cover plate 8 when the armrest 3 is not attached, so if the insertion hole 31 is exposed. It is possible to completely prevent troubles such as a child's fingertips being inserted into the container.

In particular, the cover plate 8 of the present invention is configured to firmly maintain the locked state by locking the locking claws 81 and 82 projecting upward and downward on the peripheral edge to the back side of the armrest 3. Therefore, unlike conventionally known lid structures, there is no fear that the lid plate will be removed even if a child or the like plays with it from the front side, making it extremely safe.

In addition, although the cover plate 8 of the present invention is firmly locked to the armrest 3, when it is desired to remove it, the space formed between the back side of the armrest 3 and the receiver 7 is removed. The lid can be removed by a simple operation of inserting a thin push-up tool 9 like a coin into the lid and pushing up the locking claw 82, and will not come off accidentally due to mischief by a child. The plate 8 also has excellent functional flexibility in that it can be easily removed if an adult wishes to do so.

Furthermore, the present invention has the tip (end portion) of the armrest 3.
Since the cover plate 8 fitted into the armrest 3 is attached so as to maintain the same plane as the end surface of the armrest 3, that is, it is attached flush with the end surface of the armrest 3, the armrest 3 looks better when the guard 6 is not used. It has the characteristic that it can be made into an extremely excellent product.
