Description

[Detailed description of the invention] The present invention relates to a heating device such as an electric blanket or a bed blanket, which has a heater unit and a bag-like outer fabric covering the heater unit that can be removed. The aim is to provide a structure that can firmly fix the entire structure without causing wrinkles.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof. In FIG. 1, reference numeral 1 denotes an outer fabric made of blanket fabric constructed in the form of a bag. On one long side of this outer fabric 1, there is provided a zipper 2 that can be opened and closed to take in and take out a heater unit, which will be described later. ing. 3 is a male fastener provided on one short side of the outer fabric 1; 4 is a string provided on both ends of the other short side of the outer fabric 1. Reference numeral 5 denotes a plurality of contact fasteners provided on the long side and one short side of the outer fabric 1, and the contact fastener 5 is provided with a large number of raised hooks 6 planted on the fabric as shown in Fig. 4. . In FIG. 2, reference numeral 7 denotes a heater unit incorporating a heating element 8, and one short side of the heater unit 7 is provided with a female fastener 9 that engages with the male fastener 3 of the outer fabric 1. 10 is a fixing hole provided on the other short side of the heater unit 7. Reference numeral 11 denotes a contact fastener 11 which is sewn and fixed over the entire length of the long side and one short side of the heater unit 7 in correspondence with the contact fastener 5 of the outer fabric 1. As shown in FIG. 4, the contact surface fastener 5
An engaging portion 12 made of a large number of raised piles is provided with which the raised hooks 6 engage.

In the above configuration, the outer cloth 1 and the heater unit 7
When fixing, as shown in FIG. The string 4 is passed through the fixing hole 10 of the heater unit 7 and tied and fixed. And outer cloth 1
and part of the long side and short side of the heater unit 7,
It is fixed by the engagement of the contact surface fasteners 5 and 11. In this case, since the contact surface fastener 11 is sewn and fixed across the long sides and one short side of the heater unit 7, the ends of the heater unit 7 can be reinforced, and Even if there are variations in the mounting position of the contact surface fastener 5 provided on the outer fabric 1 side or dimensional changes occur due to washing of the outer fabric 1, both can be securely fixed without any problem.

In the above embodiment, the contact surface fastener 5 was provided on the outer fabric 1 side, and the contact surface fastener 11 with a raised pile was provided on the unit 7 side.
On the contrary, it goes without saying that a contact fastener with a raised pile may be provided on the outer fabric 1 side, and a contact fastener with a raised hook may be provided on the unit 7 side so that the two are engaged. In addition, the heater unit 7 and the outer fabric 1 have fasteners 3 and 9 on one side.
Although it was fixed in a fixed position by the engagement of the buttons and hooks, it may also be fixed by the engagement of the buttons and hooks.

As described above, the present invention includes a substantially rectangular heater unit and a substantially rectangular outer fabric that houses the heater unit, and includes mounting means on one short side of each of the heater unit and the outer fabric. A contact surface fastener is fixed to almost the entirety of two long sides and one short side of this heater unit, and a contact surface is also attached to two long sides and one short side of the above-mentioned outer fabric facing the contact surface fastener. Since the fasteners are provided, the heater unit and the outer fabric can be firmly fixed all around, and one short side and two long sides of the heater unit can be reinforced with contact surface fasteners. Even if there are variations in the mounting position of the contact surface fastener on the outer fabric side or dimensional changes due to washing, both can be fixed without any problems.
