Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a finger-

More particularly, the present invention relates to a device for preventing fingers for a door, which is installed in a door (including both a sliding door and a sliding door system and used in the meaning including both doors and a door frame) The present invention relates to a finger interlocking device for a door.

As is well known, the doors are of sliding or hinged type. The problem is that both the sliding door and the hinged door have a very high risk of injuring their fingers or hands in the process of closing the open door.

Especially, in the case of the school, there are many young children, so that a hand or a finger is caught in a gap between the door and the door frame and is seriously injured frequently.

Therefore, in order to solve the above-mentioned problems, the applicant of the present invention has proposed a method for controlling a window-type buffer cushion which is disposed alternately at an inner side of an end portion of a window frame and an outer end portion of a window as in Korean Patent Registration No. 10-1548522 A pressure-reducing chamber type buffer, wherein the rod type buffer comprises a cylinder; A rod installed in the cylinder so as to move forward and backward and having a head at an end thereof; And a damper for urging the rod forward, wherein a head of a rod protruded by an elastic portion is protruded on a front surface of the cylinder, and the decompression chamber type buffer comprises a decompression chamfer Wherein the rod head of the rod-like buffer rebounded on the lug portion is configured to secure the safety through hand-fit prevention configured to buffer an instantaneous impact on the rod during the closing of the window set structure while entering the chamber chamber The present invention is directed to an opening / closing assisting device for a window set structure for securing a low noise sensitivity.

However, the Applicant has developed and used such a device. As a result, the biggest problem is that the air inside the cylinder must completely pass through the discharge hole having a small diameter so that the door is completely closed, The disadvantage of having to close the door until all of the air in the air is exhausted and waiting for it to take a considerable amount of time is boring.

Further, the structure is complicated and difficult to manufacture, which causes a problem of increase in manufacturing cost.

FIG. 1 is an exploded perspective view of a door fingertip prevention apparatus according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the combined state of FIG. 1, FIG. 4 is a view for showing the operating state of the present invention. FIG. 4 is a state before the door is closed, FIG. 4 is a state where the instantaneous frictional force acts on the flexible stick as the flexible stick is pushed back, And (c) the door is closed by slowly closing the door and pushing the brace, so that the flexible stick is pushed out to close the door, and FIGS. 5 to 10 are sectional views of other embodiments of the present invention.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The finger interlock device 100 for a door according to the present invention comprises a main body 110 attached to a door A or a door frame B with an attachment means and a main body 110 formed on one side of the main body 110, A flexible stick 120 slidably fitted in the stick built-in groove 115 and having a pair of struts 121; and a flexible stick 120 which elastically supports one end of the flexible stick 120, And a lid 140 coupled to the main body 110 to prevent the flexible stick 120 and the spring 130 from separating from each other.

The outer guide 113 supports the outer side of the flexible stick 120 and the inner guide 114 supports the inner side of the flexible stick 120. The inner guide 114 supports the outer side of the flexible stick 120, . That is, the guides 113 and 114 serve as rails for guiding the flexible stick 120 to be slidable.

The flexible stick 120 is formed so that the horizontal groove 115a, the curved groove 115b and the vertical groove 115c are connected to each other in a continuous manner, that is, in the stick built-in groove 115 formed inside the guides 113 and 114, Is embedded in the stick built-in groove 115 in a bent state.

In the present invention, the concept of the flexible stick 120 is very important. The flexible stick 120 is made of a flexible synthetic resin or a silicon material in a straight line. On the other hand, the brace 121 is preferably made of a hard synthetic resin. This is because unlike the flexible stick 120, a gap can be formed between the door A and the door frame B so that the hand and the finger are not hurt due to the gap.

Therefore, when the flexible stick 120 is bent and embedded in the built-in groove 115, one side is positioned in the horizontal groove 115a, the middle is positioned in the curved groove 115b, and the other side is positioned in the vertical groove 115c. At this time, the intermediate portion of the flexible stick 120 is referred to as a bending portion 122. The bent portion 122 is positioned in the curved groove 115b of the built-in groove 115 of the stick. At this time, the bending portion 122 is originally unfolded by the restoring force of the flexible stick 120 itself, but it must be embedded in the bending state because it must be embedded in the curved bending groove 115b.

As a result, when the door A is closed, the braces 121 located in the horizontal grooves transmit the impact to the flexible stick 120 in a horizontal direction as soon as they strike the door frame B, The force is transmitted to the bent portion, and the bent portion strikes the outer guide 113 located behind the bent portion as it is. At the same time, at the same time, the bending portion acts on the outer guide 113 with the frictional force and the reaction, so that the flexible stick 120 is stopped instantaneously and the bracing 121 is no longer pushed backward.

Therefore, at this time, a clearance is generated between the door A and the door frame B by the length of the bracket 121, so that even if the hands or fingers of the children are caught, the hand or finger is not hurt by the spacing space.

When the door A is closed slowly, the flexible stick 120 overcomes the elastic force of the spring 130 by the force of the person closing the door A and descends along the curved groove and the vertical groove 115c, 121 are also retractable so that the door (A) is finally closed. At this time, the spring 130 elastically supporting the lower end of the flexible stick 120 is set to have a spring force so as not to have enough elasticity to overcome the weight and frictional force of the door A. Once the door A is closed, Is retained in the horizontal groove 115a.

When the door A is opened, the flexible stick 120 is raised by the force of the spring 130, and the elevated flexible stick 120 pushes the brace 121, and the brace 121 again moves forward As shown in Fig.

In the present invention, the flexible stick 120 may be provided in the body 110 in a pair, that is, in pairs. That is, the main body 110 is provided with a pair of stick built-in grooves 115 capable of mounting a pair of flexible sticks 120 so as to be opposed to each other, and is formed such that the elastic force is applied by the respective springs 130, It is possible to suppress the closing of the door A by a force twice as much as that formed by one door 120, thereby preventing the door from becoming more effective.

The present invention is characterized in that a locking protrusion 160 is formed in the curved groove 115b of the guides 113 and 114 and a locking groove 170 for locking the locking protrusion 160 is formed on the flexible portion 122 of the flexible stick 120 The engaging groove 170 of the flexible stick 120 is engaged with the engaging jaws of the guides 113 and 114 so as to prevent the frictional force acting on the flexible stick 120 from weakening due to the frictional force acting on the flexible stick 120, (160) so as to prevent the flexible stick (120) from falling. In this case as well, if the door A is closed gradually, the elastic stick 120 is in a state in which the latching groove of the flexible stick 120 is not caught by the latching jaws of the guides 113 and 114, Can be lowered.

A step 123 is formed in the flexible stick 120 and the step 123 can be caught by the stopper 150 acting as an elastic force by the elastic spring 151, So that the bracket 121 can be prevented from being projected beyond the door A forcibly.

The present invention is also characterized in that a wrinkle portion 180 is formed on one side of the flexible stick 120 so that when the brace 121 abuts against the door frame B and retreats back by impact, The outer diameter of the wrinkle portion 180 is closely attached to the inner surfaces of the guides 113 and 114 forming the horizontal grooves 115a so as to prevent retraction of the braces 121 do. Therefore, when the brace 121 is not retreated, an interval of the braces 121 is formed between the door A and the door frame B, so that the hands and the fingers can be prevented from being caught and injured.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
