Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of daily necessities, and particularly to a foldable floor mat inner core structure.
Background Art
[0002] In existing floor mat products such as bathroom mats and doormats, in most cases, a one-piece sponge or high-density polyurethane is used as the filling inner core.
[0003] However, the applicant has discovered that the prior art has at least the following technical problems.
[0004] In the design of conventional floor mats, since the filling inner core adopts a complete one-piece structure, the floor mat occupies a relatively large space during storage, and the size after storage still exceeds the capacity range of the washing machine, resulting in inconvenience in storing, carrying, and washing the floor mat. Furthermore, when the user folds the floor mat, in order to reduce the occupied space in the storage state, a certain amount of external force is inevitably applied. Since the existing inner core has no effective stress dispersion structure, the inner core is easily damaged or deformed at the folded position.
[0005] Furthermore, since the filling inner core is made of a sponge with excellent elasticity, the floor mat easily bounces back after being folded, making it difficult to maintain the folded state and further difficult to store.
[0006] In view of the above, the present invention is proposed.
Summary of the Invention
Problems to be Solved by the Invention
[0007] The object of the present invention is to solve the technical problems existing in the prior art that the inner core for filling the conventional floor mat has design defects, adopts a complete one-piece structure, lacks an effective stress dispersion structure, occupies a relatively large space when storing the floor mat, and the inner core is easily damaged or deformed at the folded part. To achieve this, a foldable inner core structure for a floor mat is provided. Hereinafter, among various technical solutions according to the present invention, various technical effects that can be achieved by preferred technical solutions will be described in detail.
Means for Solving the Problem
[0008] In order to achieve the above object, the present invention provides the following technical solutions.
[0009] The foldable inner core structure for a floor mat according to the present invention includes an inner core layer, and at least one groove is formed on the upper surface and / or the lower surface of the inner core layer. The groove extends parallel to the longitudinal direction, width direction or diagonal direction of the inner core layer and is provided through the inner core layer.
[0010] Preferably, the grooves on the same surface are arranged in parallel.

Advantages of the Invention
[0019] The preferred technical solution of the present invention can achieve at least the following technical effects.
[0020] In the present invention, since the inner core for filling the conventional floor mat has design defects and adopts a complete one-piece structure, it lacks an effective stress dispersion structure, occupies a relatively large space when storing the floor mat, and is prone to damage or deformation of the inner core at the folded part. To solve the technical problems existing in the prior art, a foldable floor mat inner core structure is provided.

The groove extends parallel to the longitudinal direction, width direction, or diagonal direction of the inner core layer and is provided through the inner core layer. Thereby, when folding, the inner core layer naturally bends along the direction of the groove, reducing the occupied space after folding, making the folded floor mat more compact, enabling the floor mat to easily fit within the capacity range of a household washing machine, improving the convenience of washing, as well as the convenience of storage and carrying. Furthermore, the provision of the groove also provides a natural bending region in the inner core layer. When folding, the groove has a structure that evenly disperses the stress generated during folding, avoiding damage to the inner core layer at the folding location, thereby improving the structural stability of the floor mat in the folded state.

[0032] When the grooves on the upper surface and the grooves on the lower surface are provided in a staggered pattern, folding the inner core layer provides more possible folding configurations, thereby improving the flexibility of folding and enabling the floor mat to meet various folding requirements.
[0033] As a possible embodiment, the groove is formed by a non-penetrating cut.
[0034] In such a configuration, not only the strength of the overall structure of the inner core layer is maintained, but also an effective guiding action is achieved by the grooves when folding.

[0038] In such a configuration, the usage needs in various scenarios can be satisfied.
[0039] As a possible embodiment, the inner core layer includes a polyurethane sponge layer, a recycled sponge layer, or a rubber sponge layer.

[0042] In such a configuration, the usage needs in various scenarios can be satisfied.
[0043] As a possible embodiment, the maximum depth of the groove is 0.5 cm to 4.5 cm.
[0044] In such a configuration, the flexibility of folding is ensured by the groove, and the stress generated during folding is effectively dispersed.
[0045] Note that the thickness of the inner core layer, the number and maximum depth of the grooves, and the interval between the grooves may be designed according to the usage needs so as to be applicable to the floor mats in various usage scenarios.
