Description

Door stopper

Technical Field

The utility model belongs to the technical field of children's protective articles for use, concretely relates to door stopper for door leaf is spacing opened.

Background

The door stopper, also called as a door stop, is a device which is padded under the door leaf to limit the door leaf and prevent the door leaf from being accidentally closed under the use of wind or external force. On one hand, the adverse effect of noise and impact force generated by sudden closing of the door due to the action of wind after the door is opened on the structure of people or the door can be avoided, and on the other hand, fingers can be prevented from being injured by children who operate and close the door leaf when playing.

The existing door plug is provided with two inclined planes with different lengths and or inclination angles, so that the door plug is suitable for doors with different ground clearances; meanwhile, the whole structure is mostly a whole solid structure. For example, CN205663332U, a chinese utility model patent application for a door stopper with easy storage, discloses a door stopper with a storage fixing sleeve 1, the main body of which is a wedge 4 with two inclined planes; CN206429092U a door plug of chinese utility model discloses a door plug with an additional module B to produce different heights for use by separating or combining module a and module B to match door leaves with different ground clearances; CN206429093U a chinese utility model patent of combined door stopper, discloses a combined door stopper with adjustable module B, which makes its inclined plane length adjustable through independent module a or different combination states of module B and module a, thereby making the door stopper adaptable to wider ground clearance.

For all door plugs in the prior art including the above patents, the inclined plane for blocking the bottom of the door leaf is solid, the door leaf inquiry of different ground clearances is blocked mainly by the difference of the distance between each point on the inclined plane and the bottom surface of the door plug, and the main acting force is derived from the matching of the shape of the inclined plane and the bottom of the door leaf (the door plug is fixed by the friction force between the bottom surface and the ground under the action of the inclined plane). The existing optimization scheme is to arrange soft materials or anti-slip edges or points on the inclined surface to increase the friction force, which can be improved to a certain extent but is not fundamentally solved.

In addition, such a structure can only achieve the limiting effect when the door leaf is at the maximum opening position (or when other supporting force is applied to the back surface), and if the door leaf is to be limited at any other position, a door plug may need to be arranged on each of the front surface and the back surface. Therefore, a need exists for a novel door plug which is convenient to use, has a good limiting effect, and is not easy to damage the door plug and the door leaf.

Detailed Description

In order to better understand the invention for those skilled in the art and to define the claimed scope more clearly, the invention will be described in detail below with respect to certain specific embodiments of the invention. It should be noted that the following description is only a few examples of the present invention, and the specific and direct descriptions of the related structures are only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of the present invention. Conventional alternatives and substitutions made by those skilled in the art in light of the teachings of the present disclosure should be considered as within the scope of the present disclosure.

As shown in fig. 1 to 3, a door plug is used to be placed at the bottom of a door leaf when the door leaf is opened, so as to limit the door leaf, prevent the door leaf from being accidentally closed under the action of wind and the like, and avoid the adverse effect on the service life of a door frame or the door leaf caused by impact force and the safety problem caused by the adverse effect.

The door plug comprises a bottom surface 13, a first supporting surface 11 and a second supporting surface 12 which are respectively arranged at two ends of the bottom surface 13 and are made of tough materials, wherein the first supporting surface 11 and the second supporting surface 12 have different lengths and/or inclination angles, so that the first supporting surface and the second supporting surface can be suitable for door leaves with different ground clearances.

Different from the traditional door stopper, the first supporting surface 11 and the second supporting surface 12 of the door stopper of the present invention are both designed to be in a long strip shape (i.e. the length thereof is larger than the width and the thickness), the lower ends of the two are respectively connected with the two ends of the bottom surface 13, and the upper ends are vacant, obviously, the two and the bottom surface 13 are hollowed out to form a cavity; this is a distinct structure and shape from the traditional solid door plug, so that on one hand, the overall shape of the door plug can be distinct from the existing one and more beautiful, and on the other hand, the door plug can be supported and limited by the toughness of the first support surface 11 or the second support surface 12, and compared with the traditional pure friction force or slight deformation of surface material, the effect of stopping and limiting is better, and the accidental closing of the door leaf caused by natural wind and children unauthorized operation can be avoided. Of course, the first support surface 11 and the second support surface 12 do not necessarily need to be connected to both ends of the bottom surface 13, and it is also possible to arrange them in the middle of the bottom surface 13, only to ensure that they are arranged at an angle.

In order to enable the structural strength of the door plug to meet the use requirement, the first supporting surface 11, the bottom surface 13 and the second supporting surface 12 may be integrally formed, that is, the door plug with the structure is formed by one-step molding through a mold, or is obtained by processing and molding materials such as iron, stainless steel and the like; so that the connection of the first support surface 11 to the bottom surface 13 and the connection of the bottom surface 13 to the second support surface 12 are structurally strong.

The angles α and β of the first support surface 11 and the second support surface 12 relative to the bottom surface 13 may be 25-35 ° and 15-25 °, α and β are preferably 30 ° and 20 °, respectively, the gap between the two support surfaces may be 2.5-5cm and 0.5-3 cm., respectively, other values or ranges of values may be provided, and the first support surface 11 and the second support surface 12 are not necessarily flat but may be curved.

Therefore, the first supporting surface 11, the second supporting surface 12 and the bottom surface 13 are similar to ∠, the two supporting surfaces are only contacted with the bottom surface at the connection position, the supporting surfaces can deform relative to the bottom surface by adopting a flexible material, so that the relative included angle between the two supporting surfaces is reduced, the limiting force is increased, and the door leaf can be limited in two aspects at any position due to the increase of the limiting force.

In addition, in order to increase the strength and toughness of the two supporting surfaces, the first supporting surface 11 and the second supporting surface 12 may also have supporting members separately or simultaneously, the supporting members include a first supporting member 111 and a second supporting member 121, the first supporting member 111 is a rib disposed on the back surface of the first supporting surface 11, and the second supporting member 121 is a leg having two ends disposed on the back surface of the second supporting surface 12 and the upper surface of the bottom surface 13, respectively; the first supporting part 111 in the form of the convex rib and the second supporting part 121 in the form of the leg can increase the supporting force of the two supporting surfaces under the condition of unchanged material or unchanged thickness; furthermore, the legs of the second support 121 are adapted to deform in response to the second support surface 12, and are therefore preferably arranged at the same inclination as the second support surface 12 (typically at a greater angle).

Preferably, the bottom surface 13 is further provided with a supporting block 131, and the supporting block 131 can limit the maximum deformation angle of the first supporting surface 11 and/or the second supporting surface 12, so as to avoid breaking the two supporting surfaces in extreme cases; for example, as shown in fig. 1, the supporting block 131 is disposed below the top end of the second supporting surface 12, when the second supporting surface 12 deforms downward, the material property of the supporting surface itself and the second supporting member 121 may generate resistance, so as to generate a limiting action force on the door leaf, and when the top end of the supporting block moves downward to contact with the supporting block 131, the supporting block cannot deform further, so as to protect the second supporting surface 12, and prevent the second supporting surface from being excessively deformed and broken or elastically attenuated.

For the first support surface 11, the support block 131 may not directly function as a support, but indirectly function through the second support surface 12. Specifically, based on the above structure, the top end of the second supporting surface 12 extends to the lower side of the first supporting surface 11, the top of the first supporting surface 11 is displaced downward after being deformed, and is contacted with the top of the second supporting surface 12 after a certain degree, at this time, the second supporting surface 12 supports the first supporting surface 11 when the first supporting surface 11 is further deformed, and further, the top end of the second supporting surface 12 is extended to the lower side of the first supporting surface 11, and then the first supporting surface 11 is further deformed, and further, the second supporting surface 12 supports the

When the second supporting surface 12 is deformed to be in contact with the supporting block 131, the deformation of the first supporting surface 11 reaches a maximum value.

In fact, it is feasible and predictable to arrange the two supporting members to respectively limit the maximum deformation angles of the two supporting surfaces, or to change the structure of the supporting block 131 so that the maximum deformation angles of the two supporting surfaces can be simultaneously limited; in addition, it is possible and contemplated that the first and second supporting

members

111 and 121 may be simply changed, that is, two different types of supporting members may be used, or only one of the two supporting surfaces may be provided with a supporting member, and thus, the description thereof is omitted.

In other preferred embodiments, as shown in fig. 4-6, the door plug is composed of an inner part and an outer part, i.e. it is composed of an outer door plug 21 and an inner door plug 22, which are fitted to each other. The inner door plug 22 can be made of tough materials such as hard glue, plastics, metal or metal alloy, and can be integrally formed by injection molding or plate processing; structurally, the support consists of three major parts, namely a bottom surface, a first support surface and a second support surface; the outer door plug 21 is made of soft/soft materials such as soft rubber and silica gel, and may be assembled with the inner door plug 22 after being processed respectively (for example, by glue bonding or screw fixation), or formed by encapsulating the inner door plug 22 and the outer door plug 22 after the inner door plug 22 is added. The latter is however relatively preferred, for which purpose the outer surface of the inner plug 22 may also be provided with an encapsulation aid in the form of a corresponding protrusion or depression.

For example, a rib 221 is provided on the bottom surface of the inner plug 22 as shown in fig. 6, so that the encapsulated outer plug 21 can be firmly encapsulated with the inner plug 22 on the bottom surface by the rib 221. At this time, the first supporting member 111, the second supporting member 121 and the supporting block 131 are preferably disposed on the inner door stopper 22 and integrally formed therewith. Fig. 7a and 7b are two perspective views of an alternative structure of the inner door stopper 22 in the embodiment, to show its encapsulation aid structure on two support surfaces and the bottom surface, respectively; as can be seen in fig. 7a, b, it employs several bumps 222 provided on the outer surface of the inner door plug 22 as encapsulation aid; in fact, other shapes such as grid or array-like bumps or grooves are also possible, which can be expected in the prior art and will not be described in detail.

It should be noted that, the above description is related to the door plug having two supporting surfaces (i.e. the first supporting surface 11 and the second supporting surface 12), and it is obvious that it is also feasible and predictable to reduce the number of the supporting surfaces and only provide one supporting surface (the first supporting surface 11 or the second supporting surface 12), and the description thereof is omitted; in addition, without mutual conflict, a person skilled in the art may reasonably recombine the above technical features within a reasonable range, and the present invention also belongs to the implementation scope of the present invention.

The utility model discloses the structure to traditional door stopper has carried out the innovation, becomes it by becoming the contained angle setting and only constitute at the bottom surface and the holding surface that the junction links to each other for both become by the integrative structure of direct rigidity and can make the holding surface carry out the toughness of deformation for the tie point and press from both sides angle structure, thereby effectively increase spacing power, promote the security, and can carry out spacingly to the door leaf in the optional position, but its structure and manufacturing cost obviously increase, be an effective and practical novel door stopper.
